Through this, a user can easily and safely control the exercise loads without separate manipulation for input.

Description

Technical Field

The present disclosure relates generally to a muscle exercise device using a cable. More particularly, the present disclosure relates to a muscle exercise device with which a user can perform a muscle exercise by using a cable.

BACKGROUND ART

In general, a muscle exercise device used for increasing muscular strength is designed to repeat muscle relaxation and contraction while a lever connected to a weight of a predetermined unit of weight is pushed or pulled.

Such an exercise device includes various types of exercise devices, such as an arm curl machine for biceps exercises, a chest press or butterfly machine for exercises for chest, such as pectoralis major, and a pull-up device for a muscle exercise.

Recently, as part of self-management, a home workout, which is exercise for health management at home which is my own resting place without jogging or visiting a fitness center has become an issue. In response to this issue, various types of exercise devices for a home workout have been proposed, and a new phrase called a home workout group has been created.

As one example of a muscle exercise device for a home workout, a muscle exercise device using a cable is being used. Inside the muscle exercise device, a drive motor which provides an exercise load is installed, and an exercise load supplied from the drive motor is transmitted to a user through the cable so that the user performs a muscle exercise by pulling or releasing the cable.

In the case of muscle exercise using a muscle exercise device, a normal muscle exercise device using weights and a muscle exercise device using a drive motor are both required to provide a safe exercise environment while an exercise load is provided from the weights or the drive motor.

For example, there may occur the situation that while exercising with an exercise load provided from the drive motor, a user urgently wants to remove the exercise load due to lack of strength.

In this situation, in the case of a typical muscle exercise device using weights, for example, in a muscle exercise using a bench press, a barbell may be placed on a support to remove an exercise load caused by weights.

However, the muscle exercise device using a drive motor optimized for a home work is required to have a simplified structure, and thus it is not realistic to apply a structure such as a support of a bench press to the device.

In order to solve this problem, an exercise device disclosed in U.S. Pat. No. 10,589,163 has an acceleration sensor installed therein and enters a stop mode when acceleration measured by the acceleration sensor is equal to or greater than a threshold value.

However, in the case of the exercise device disclosed in the U.S. Pat. No. 10,589,163, when the acceleration exceeds the threshold value, it may be seen that a user's movement situation has already entered an unsafe state. In this case, in a normal muscle exercise device, removal of an exercise load by a user placing a barbell on a support, that is, removal of an exercise load by a user during exercise, cannot be realized.

In addition, in the event of an emergency that a user did not intend, for example, when the body leans to one side, it is impossible to prevent accidents which may occur due to the imbalance of posture since the exercise device enters the stop mode only when acceleration is equal to or greater than the threshold value.

For another example, recently, products that remove an exercise load of a drive motor through the manipulation of a button switch by installing the button switch capable of performing short-distance communication such as Bluetooth on a handle grip or a handle bar connected to a cable are being released.

However, in the case of the button switch installed on the handle bar, in an emergency situation, for example, in a situation where a user is struggling with a current exercise load, it is difficult for the user to find the button switch, and the user may fall down or have one hand falling off from the handlebar in the process of pressing the button switch.

This is because the position of a hand gripping the handle bar may vary for each user, so it is difficult to change the position of the hand gripping the handle bar in a state in which an exercise load is applied depending on the position of the button switch, and the hand may fall off from the handle bar in the process of changing the position of the hand

Voice recognition technology may also be applied due to the high utilization of voice recognition technology in recent years. However, when a user exercises in ambient noise, for example, while music or TV is on, a voice recognition rate is significantly lowered, making the use of the voice recognition technology difficult.

DISCLOSURE OF INVENTION

Technical Problem

The present disclosure is intended to propose a muscle exercise device using a cable in which an exercise load supplied from a drive motor can be easily and stably controlled by a user.

In addition, the present disclosure is intended to propose a muscle exercise device using a cable in which when a user is intended to remove an exercise load in a state in which the exercise load supplied from the drive motor is too high to be handled by the user, a convenient user interface for the removal of the exercise load can be provided.

Furthermore, the present disclosure is intended to propose a muscle exercise device using a cable in which an emergency situation unintended by a user is detected such that an exercise load can be removed.

Additionally, the present disclosure is intended to propose a user interface through which an exercise load is easily and stably increased to a target load desired by a user at the initial stage of an exercise load.

In addition, the present disclosure is intended to propose a muscle exercise device using a cable in which an exercise load can be easily and stably removed in an emergency situation or a situation in which the exercise load is too high for a user while the exercise load is increased to the target load.

Furthermore, the present disclosure is intended to propose a muscle exercise device using a cable in which an exercise process can be visually recognized while a muscle exercise is performed by using a cable.

Additionally, the present disclosure is intended to a mat-type muscle exercise device using a cable in which an accident can be prevented when a user steps on the upper surface of the device.

Solution to Problem

In the muscle exercise device using a cable according to an embodiment of the present disclosure, exercise loads provided by a pair of load supply modules may be controlled based on a combination of moving-out positions of a pair of cables.

For example, the pair of load supply modules may be installed in a device body and may each provide exercise loads.

Each of the pair of cables may extend outside the device body while the pair of cables is connected respectively to the load supply modules. In addition, the cables may respectively transmit the exercise loads of the load supply modules to the outside.

The muscle exercise device according to the embodiment of the present disclosure may include a device control part. The device control part may control an exercise load provided by each of the load supply modules according to the combination of moving-out positions detected by a pair of position detection parts.

For example, the device control part may control each of the load supply modules to reduce an exercise load when deviation between the moving-out positions detected by the pair of position detection parts exceeds a preset reference deviation.

For example, when the deviation between the moving-out positions exceeds the reference deviation while the device control part controls each of the load supply modules to increase an exercise load to a preset target load, the device control part may control each of the load supply modules to reduce the exercise load.

For example, when the deviation between the moving-out positions exceeds the reference deviation, the device control part may control each of the load supply modules to reduce the exercise load to a preregistered base load.

The device control part according to the embodiment of the present disclosure may control the pair of load supply modules according to any one of a first exercise type, a second exercise type, and a third exercise type.

Here, the first exercise type may, for example, be an exercise in which the pair of cables is moved in and out in the same directions. The second exercise type may, for example, be an exercise in which the pair of cables is moved in and out in directions different from each other. In addition, the third exercise type may, for example, be an exercise in which any one of the pair of cables is moved in and out.

For example, when the deviation between the moving-out positions exceeds the reference deviation while the device control part controls the pair of load supply modules according to the first exercise type, the device control part may control each of the load supply modules to reduce the exercise load.

In the embodiment of the present disclosure, when it is recognized that a pre-registered exercise resuming condition is satisfied after the device control part reduces the exercise load of each of the load supply modules, the device control part may control each of the load supply modules to increase the exercise load.

For example, when the deviation between the moving-out positions is within a preset normal deviation and at least one cycle of exercise is detected based on the moving-out positions detected by the pair of position detection parts, the device control part may recognize that the exercise resuming condition is satisfied.

When a preregistered load application condition is satisfied during a user's initial movement, the device control part according to the embodiment of the present disclosure may control each of the pair of load supply modules to increase the exercise load to the target load.

Here, the device control part may determine whether the load application condition is satisfied based on the combination of the moving-out positions detected by the pair of position detection parts.

For example, the load application condition may include an exercise preparation condition and a preparation completion condition.

The exercise preparation condition may be a state in which the outward movements of the pair of cables are detected based on the moving-out positions detected by the position detection parts during the initial movement. In addition, the preparation completion condition may be a state in which the moving-out positions of the pair of cables are maintained for a preset period of preparation completion time based on the moving-out positions detected by the position detection parts, respectively.

The muscle exercise device according to the embodiment of the present disclosure may include a speed calculation part. The speed calculation part may calculate the speed of each cable based on the moving-out position detected by each of the position detection parts.

For example, when the speeds of the cables calculated by the speed calculation part are maintained within a preset completion speed range for the period of preparation completion time after it is recognized that the exercise preparation condition is satisfied, the device control part may recognize that the preparation completion condition is satisfied.

For example, while the deviation between the moving-out positions detected by the position detection parts is maintained within the preset normal deviation, the device control part may determine that the preparation completion condition is satisfied.

For example, while each of the load supply modules increases the exercise load to the target load, the device control part may calculate the deviation between the moving-out positions detected by the position detection parts. In addition, when the calculated deviation exceeds the preset reference deviation, the device control part may control each of the load supply modules to reduce the exercise load.

In the embodiment of the present disclosure, the pair of cables may be moved outside the device body from the respective opposite edges of the device body in a longitudinal direction thereof.

For example, the muscle exercise device may further include a plurality of LED modules disposed along a longitudinal direction thereof on at least one portion of opposite edge portions of the device body in a width direction thereof.

Here, the device control part may control blinking of the plurality of LED modules in accordance with the moving-out positions detected by the position detection parts, respectively.

For example, the plurality of LED modules may include a plurality of first column LED modules disposed at a first side from a center of the device body in the longitudinal direction thereof, and a plurality of second column LED modules disposed at a second side from the center of the device body.

Here, the device control part may control the blinking of the plurality of first column LED modules and the plurality of second column LED modules in accordance with the moving-out positions detected by the associated position detection parts by matching the position detection parts to the plurality of first column LED modules and the plurality of second column LED modules, respectively.

For example, the device control part may light some LED modules among the plurality of LED modules so that the number of the some LED modules corresponds to the moving-out positions in any one direction from the center of the device body in the longitudinal direction.

The muscle exercise device according to the embodiment of the present disclosure may include a plurality of wheel modules and a wheel detection part.

For example, the plurality of wheel modules may be installed on the lower surface of the device body so that the plurality of wheel modules can be moved in and out of the device body. In addition, the wheel detection part may detect whether each of the wheel modules is in a state capable of being moved out.

Here, when it is detected by the wheel detection part that at least one of the plurality of wheel modules is in a state capable of being moved out of the device body, the device control part may light the plurality of LED modules in any one of a preset light emitting color and a preset light emitting pattern.

The device control part according to the embodiment of the present disclosure may control the pair of load supply modules according to any one of a plurality of exercise levels. Here, the plurality of exercise levels may include an exercise load for each different level and cable speed for each level.

For example, when the speed of the cable calculated by the speed calculation part is faster than the speed of the cable for each level of a present exercise level, the device control part may control each of the load supply modules so that an exercise load is reduced when the cable is moved in.

Here, when the speed of the cable calculated by the speed calculation part is faster than the speed of the cable for each level of the present exercise level, the device control part may transmit a level changeable signal. In addition, when receiving a level change request signal from an external device, the device control part may control each of the load supply modules for an exercise level corresponding to the level change request signal.

Advantageous Effects of Invention

The muscle exercise device using a cable according to the present disclosure may have at least one of the following effects.

First, exercise loads provided from load supply modules may be controlled based on the moving-out positions of the pair of cables, thereby enabling a user to easily and stably control the exercise loads without separate manipulation for input.

Second, in a state in which an exercise load is too high for a user, when the user intends to rapidly remove the exercise load, the user may remove the exercise load only by the simple movement of a handle bar which the user grips, thereby providing a convenient user interface.

Third, an emergency situation unintended by a user may be detected through the moving-out position of a cable to remove an exercise load, thereby enabling safe muscle exercise

Fourth, when an exercise load is increased to a target load desired by a user at an initial stage of exercise, it may be detected that a user is preparing to exercise, based on the moving-out position of a cable, and the exercise load may be provided as the target load, thereby providing an easy and stable user interface.

Fifth, when an emergency situation or an excessively high exercise load occurs in the process of increasing an exercise load to a target load, a user may remove the exercise load by simply moving the handle bar gripped by the user, thereby providing an easy and safe user interface.

Sixth, the blinking of the plurality of LED modules may be performed in accordance with the moving-out positions of the cables, thereby enabling the process of performing a muscle exercise to be visually recognized and concentration on the muscle exercise to be increased.

Seventh, a state in which the wheel modules can be moved out may be visually recognized by a user through the LED modules, thereby preventing the risk of accidents.

The present disclosure relates to a muscle exercise device using a cable.

In the muscle exercise device according to the embodiment of the present disclosure, exercise loads provided by a pair of load supply modules may be controlled based on the combination of moving-out positions of a pair of cables.

Advantages and characteristics of the present disclosure, and methods for achieving them will become clear with reference to embodiments described later in detail in con-junction with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below and may be implemented in a variety of different forms. However, these embodiments are provided to make the disclosure of the present invention complete and to completely inform those skilled in the art of the scope of the invention to which the present disclosure belongs, and the present disclosure is only defined by the scope of the claims. The same reference numbers designate the same elements throughout the specification.

FIG. 1 is a perspective view of a muscle exercise device 10 using cables 210 and 220 according to an embodiment of the present disclosure.

As illustrated in FIG. 1, the muscle exercise device 10 according to the embodiment of the present disclosure may include a device body 110. In the embodiment of the present disclosure, the device body 110 may have the shape of a mat.

For example, with the device body 110 seated on an indoor or outdoor floor, a user steps on the device body 110 and exercises by using the pair of cables 210 and 220 extending from the device body 110 to the outside (see FIG. 4).

The pair of cables 210 and 220 may extend from the inside of the device body 110 to the outside. In the embodiment of the present disclosure, each of the cables 210 and 220 is moved outside the device body 110 from opposite edges of the device body 110 in a longitudinal direction L thereof. As illustrated in FIG. 1, cable guide modules 181a and 181b which guide the inward and outward movements of the cables 210 and 220 may be installed at the opposite edges of the device body 110 in the longitudinal direction L thereof.

In addition, a gripping instrument for a user to grip and exercise may be connected to the pair of cables 210 and 220. In FIG. 4, the cables 210 and 220 are respectively connected to the opposite ends of a handle bar. In addition, a grip such as a D-type grip may be connected to each of the cables 210 and 220 at opposite sides, and various types of gripping instruments for exercise may be connected thereto.

FIG. 2 is a control block diagram of the muscle exercise device 10 using the cables 210 and 220 according to the embodiment of the present disclosure.

The muscle exercise device 10 according to the embodiment of the present disclosure may include the pair of load supply modules 111 and 112. Hereinafter, for convenience of explanation, the pair of load supply modules 111 and 112 is defined respectively as a first load supply module 111 and a second load supply module 112. In addition, in the pair of cables 210 and 220, a cable 210, 220 which is connected to the first load supply module 111 and transmits an exercise load may be defined as a first cable 210, and a cable 210, 220 connected to the second load supply module 112 may be defined as a second cable 220.

As illustrated in FIG. 3, the first load supply module 111 according to the embodiment of the present disclosure may include a first drive motor 111a, a first output pulley 111b, and a first timing belt 111c.

The first drive motor 111a may be installed inside the device body 110 to generate an output load according to clockwise/counterclockwise rotation. In the embodiment of the present disclosure, a user may receive an exercise load when pulling the first cable 210. In addition, when a user moves the first cable 210 in a direction in which the first cable 210 is moved in the device body 110, the first cable 210 may be moved relatively easily due to the exercise load.

The first timing belt 111c according to the embodiment of the present disclosure may connect the first drive motor 111a with the first output pulley 111b such that the first drive motor 111a and the first output pulley 111b can rotate in cooperation with each other.

In the embodiment of the present disclosure, a first bobbin on which the first cable 210 is wound may be coaxially coupled to the first output pulley 111b so as to rotate in synchronization with the rotation of the first output pulley 111b, so the first drive motor 111a and the first cable 210 may operate in cooperation with each other.

The second load supply module according to the embodiment of the present disclosure may correspond to the configuration of the first load supply module, and may include a second drive motor 112a, a second output pulley 112b, a second timing belt 112c, and a second bobbin. The output load of the second drive motor 112a may be transmitted through the second cable 220 wound on the second bobbin, and detailed description thereof will be omitted.

The muscle exercise device 10 according to the embodiment of the present disclosure may include a pair of position detection parts 121 and 122.

The position detection parts 121 and 122 may respectively detect the moving-out positions of the first cable 210 and the second cable 220. Hereinafter, a position detection part 121, 122 which detects the moving-out position of the first cable 210 is defined as a first position detection part 121, and a position detection part 121, 122 which detects the moving-out position of the second cable 220 is defined as a second position detection part 122.

In one embodiment, as illustrated in FIG. 3, the first position detection part 121 may detect the position change of the first timing belt 111c of the first load supply module 111, and may detect the moving-out position of the first cable 210 according to the inward and outward movements of the first cable 210. For example, the first position detection part 121 may include an encoder capable of detecting the position change of the first timing belt 111c.

Here, the second position detection part 122 may correspond to the configuration of the first position detection part 121, and detailed description thereof will be omitted.

In the embodiment illustrated in FIG. 3, the first position detection part 121 and the second position detection part 122 respectively detect the moving-out positions of the first cable 210 and the second cable 220 through the movements of the first timing belt 111c and the second timing belt 112c, but the technical idea of the present disclosure is not limited thereto.

For another example, the first position detection part 121 and the second position detection part 122 may be configured to detect the rotations of the first drive motor 111a and the second drive motor 112a, respectively, or to detect the rotations of the first output pulley 111b and the second output pulley 112b, respectively. For still another example, the first position detection part 121 and the second position detection part 122 may respectively detect the rotations of the first bobbin and the second bobbin or detect the movements of the first cable 210 and the second cable 220.

Hereinafter, a moving-out position detected by the first position detection part 121 is defined as a first moving-out position P1, and a moving-out position detected by the second position detection part 122 is defined as a second moving-out position P2.

Meanwhile, the muscle exercise device 10 according to the embodiment of the present disclosure may include a device control part 130. In one embodiment, the device control part 130 may control exercise loads provided by the first load supply module 111 and the second load supply module 112 according to the combination of the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122, respectively.

That is, when controlling exercise loads provided from the first load supply module 111 and the second load supply module 112, the device control part 130 may use the first moving-out position P1 and the second moving-out position P2 to actively perform load control without using an input method such as a conventional button switch or a voice recognition method.

Accordingly, immediate response to an emergency situation to be described later can be performed without separate manipulation or input, and the hassle of input or manipulation can be eliminated, and description thereof will be described in detail in embodiments to be described later.

In the embodiment of the present disclosure, the device control part 130 may control exercise loads provided by the first load supply module 111 and the second load supply module 112 based on deviation between the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122, respectively.

In the embodiment, the device control part 130 may control the first load supply module 111 and the second load supply module 112 to reduce exercise loads when deviation between the first moving-out position P1 and the second moving-out position P2 exceeds a preset reference deviation DR.

Referring to FIG. 4, when in a process in which a user exercises by holding the handle bar, the user's posture is unbalanced since exercise loads provided from the first load supply module 111 and the second load supply module 112 are too high for the user or for other reasons regardless of the exercise loads, the handle bar may be tilted as illustrated in FIG. 4.

When such an emergency occurs, deviation between the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122 may occur, and when the deviation between the first moving-out position P1 and the second moving-out position P2 exceeds the reference deviation DR, the device control part 130 may recognize this situation as an emergency situation and may control the first load supply module 111 and the second load supply module 112 to reduce exercise loads so that accidents occurring while the exercise loads are supplied can be prevented.

In addition, according to the muscle exercise device 10 according to the embodiment of the present disclosure, when during exercising, a user wants to remove a current exercise load since the user wants to stop the exercising or the current exercise load is excessively high for the user, the user, without separate manipulation, may remove the exercise load by artificially increasing deviation between the first moving-out position P1 and the second moving-out position P2 by tilting the handle bar as illustrated in FIG. 4.

Accordingly, without movement for separate input such as a button switch or a voice recognition method, a user may remove an exercise load only by tilting the handle bar which the user grips currently.

Hereinafter, the control process of the muscle exercise device 10 according to the embodiment of the present disclosure will be described with reference to FIGS. 5 to 7.

In the muscle exercise device 10 according to the embodiment of the present disclosure, exercise may be performed in a state in which an exercise load is increased to a target load LT and is applied at S40.

In the embodiment of the present disclosure, the muscle exercise device 10 may include a load input part through which the target load LT is input. In the embodiment, the load input part may include a device communication module 140 illustrated in FIG. 2.

The device communication module 140 may be connected to an external device 30 through a communication network 50 such as Bluetooth or Wi-Fi. For example, the external device 30 may include a mobile device such as a tablet or a smartphone.

A user may connect the muscle exercise device 10 according to the embodiment of the present disclosure and the external device 30 to each other through the communication network 50 through an application installed in the external device 30, and may input a target load LT by using the external device 30.

For another example, the load input part may include a device input part 170. The device input part 170 may be formed in the form of a button on the outside of the device body 110. Accordingly, a user may input a target load LT through the device input part 170.

As described above, when the target load LT is input through the load input part, the device control part 130 may control each of the first load supply module 111 and the second load supply module 112 to increase an exercise load to a target load LT.

The upper side of FIG. 6 is an example of a graph illustrating the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122, and the lower side of FIG. 6 is an example of a graph illustrating an exercise load provided by the first load supply module 111 or the second load supply module 112.

Referring to FIG. 6, when a user pulls the handle bar after a target load LT is input, the first moving-out position P1 and the second moving-out position P2 increase as illustrated in the upper side of FIG. 6.

Next, when a user prepares for exercise with the handle bar located at a predetermined position, for example, the user may prepare for exercise at the predetermined position from time t1 to time t2. In this case, the first moving-out position P1 and the second moving-out position P2 may be maintained at predetermined moving-out positions from time t1 to t2.

Here, when a state in which the first moving-out position P1 and the second moving-out position P2 are maintained at the predetermined positions is maintained until pre-registered preparation completion time, for example, when it is detected that the first moving-out position P1 and the second moving-out position P2 are maintained at the predetermined positions from time t1 to t2, the device control part 130 may increase an exercise load to the target load LT from time t2.

In the embodiment of the present disclosure, the device control part 130 may control each of the first load supply module 111 and the second load supply module 112 to supply a base load LB as an initial value of an exercise load. The base load LB may be preset as a value other than 0. Through this, the first cable 210 and the second cable 220 may be prevented from being suddenly pulled by a user's pulling force.

Here, the process of increasing an exercise load to the target load LT as illustrated in FIG. 7 is an example, and the technical idea of the present disclosure is not limited thereto. As in an embodiment to be described later, the target load LT may be applied based on the speed of the cable 210, 220 in addition to the first moving-out position P1 and the second moving-out position P2, and detailed description thereof will be described later.

Referring back to FIG. 5, in a state in which a target load LT is applied as an exercise load, while a user is performing muscle exercise, the first moving-out position P1 and the second moving-out position P2 of the first cable 210 and the second cable 220 may be detected respectively by the first position detection part 121 and the second position detection part 122 at S41.

In addition, the device control part 130 may calculate deviation between the first moving-out position P1 and the second moving-out position P2 detected respectively by the first position detection part 121 and the second position detection part 122 and may determine whether the deviation exceeds a preregistered reference deviation DR at S42.

Here, when the deviation between the first moving-out position P1 and the second moving-out position P2 does not exceed the reference deviation DR, the device control part 130 may recognize this situation as a normal exercise process, and may continuously compare the deviation between the first moving-out position P1 and the second moving-out position P2 with the reference deviation DR.

On the other hand, as illustrated in FIG. 4, when the handle bar is tilted due to a user's intention or other causes, deviation between the first moving-out position P1 and the second moving-out position P2 exceeds the reference deviation DR.

As illustrated in FIG. 6, from time prior to time t4, deviation between the first moving-out position P1 and the second moving-out position P2 increases and exceeds the reference deviation DR at time t4.

In this case, when it is determined that the deviation between the first moving-out position P1 and the second moving-out position P2 exceeds the reference deviation DR, the device control part 130 may control the first load supply module 111 and the second load supply module 112 to reduce exercise loads at S43.

In the embodiment of the present disclosure, the device control part 130 reduces an exercise load to the base load LB, but the exercise load may be preset to be decreased to be different from the base load LB. For example, the exercise load may be preset to be greater than the base load LB or to be smaller than the base load LB in con-sideration of an emergency situation.

As described above, when an exercise load is intended to be decreased in an emergency situation or according to a user's intention while the user is exercising by gripping the handle bar, an exercise load may be easily and stably reduced without a separate button manipulation or voice recognition process.

Meanwhile, when it is recognized that a preregistered exercise resuming condition is satisfied after the device control part 130 according to the embodiment of the present disclosure reduces exercise loads of the first load supply module 111 and the second load supply module 112, the device control part 130 may increase the exercise loads of the first load supply module 111 and the second load supply module 112. For example, the exercise loads of the first load supply module 111 and the second load supply module 112 may be increased back to the target load LT.

Here, the exercise resuming condition may be satisfied when it is recognized that a user restarts exercising after the exercise loads are reduced in a state illustrated in FIG. 4.

For example, when deviation between the first moving-out position P1 and the second moving-out position P2 is within a preset normal deviation DN and at least one cycle of exercise is detected based on the first moving-out position P1 and the second moving-out position P2, the device control part 130 may recognize that the exercise resuming condition is satisfied.

Here, in a muscle exercise having a cyclical characteristic such as a squat, a movement of standing up and sitting in a low position may be defined as one cycle.

Here, the device control part 130 may recognize one cycle based on an inflection point of each of the first moving-out position P1 and the second moving-out position P2, that is, a changing point of the moving-out and moving-in.

More specifically, referring to FIGS. 5 and 7, after an exercise load is reduced to the base load LB at S43, the device control part 130 may determine whether the first moving-out position P1 and the second moving-out position P2 move to initial positions thereof at S44.

In a situation as illustrated in FIG. 4, a user may stop exercising or may resume exercising after correcting the posture of the user's body.

When a user stops exercising, the user slowly puts down the handle bar, and the first cable 210 and the second cable 220 are moved to initial positions of the inside of the device body 110, so the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122 may be respectively measured as initial positions.

When each of the first moving-out position P1 and the second moving-out position P2 is recognized as an initial position at S44, the device control part 130 can stop exercise at S49. In FIG. 6, at time t5, each of the first moving-out position P1 and the second moving-out position P2 is recognized as the initial position, and the device control part 130 may recognize this as the end of exercise.

For example, at time t4 of FIG. 6, in a process in which the device control part 130 reduces an exercise load, when the first moving-out position P1 and the second moving-out position P2 are recognized as the initial positions before the exercise load is reduced to the base load LB, the device control part 130 may reduce the exercise load to the base load LB even after time t5. In addition, when the first moving-out position P1 and the second moving-out position P2 are recognized as the initial positions after the exercise load is reduced to the base load LB, the device control part 130 may maintain the base load LB as it is.

Meanwhile, at S44 of FIG. 5, when the first moving-out position P1 and the second moving-out position P2 are not recognized as the initial positions, the device control part 130 may determine whether deviation between the first moving-out position P1 and the second moving-out position P2 is within a preregistered normal deviation DN at S45. Through this, whether or not a user has corrected tilted posture illustrated in FIG. 4 may be first determined.

In this case, after the user has corrected the posture, a situation in which exercise is stopped may be assumed as described above. In the embodiment of the present disclosure, the device control part 130 may determine whether at least one cycle of exercise is in progress based on the first moving-out position P1 and the second moving-out position P2 detected respectively by the first position detection part 121 and the second position detection part 122 at S46, and when the handle bar is lowered without the progress of at least of exercise, as described above, the first moving-out position P1 and the second moving-out position P2 may be recognized as the initial positions at S44, and the exercise may be stopped at S49.

On the other hand, as illustrated in FIG. 7, in a process in which the device control part 130 reduces an exercise load since deviation between the first moving-out position P1 and the second moving-out position P2 exceeds the reference deviation DR at time t1 of FIG. 7, it may be recognized that the deviation is within the range of the normal deviation DN at time t2.

In addition, when the progress of one cycle of exercise is recognized based on the first moving-out position P1 and the second moving-out position P2 between time t2 and time t3 at S46, the device control part 130 may increase the exercise load to the target load LT again from time t3 at S47 to resume the exercise at S48.

Through the process, when a tilted posture occurs intentionally or for other reasons as illustrated in FIG. 4, the exercise load may be automatically reduced, and then when a user resumes exercise after correcting his or her posture, the exercise load may be automatically increased again, thereby enabling response to an emergency situation and resuming of exercise without separate manipulation.

Hereinafter, the control process of the muscle exercise device 10 using the cables 210 and 220 according to the another embodiment of the present disclosure will be described with reference to FIGS. 8 to 10. The embodiment illustrated in FIGS. 8 to 10 illustrates a process in which during initial movement for exercise, an exercise load reaches a target load LT and the exercise is performed.

Here, the upper side of FIG. 10 is a graph illustrating the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122, the middle side of FIG. 10 is a graph illustrating a speed V1 of the first cable 210 and a speed V2 of the second cable 220 calculated on the basis of the first moving-out position P1 and the second moving-out position P2, and the lower side of FIG. 10 is a graph illustrating an exercise load provided by the first load supply module 111 or the second load supply module 112.

In order to calculate the speed V1 of the first cable 210 and the speed V2 of the second cable 220, the muscle exercise device according to the embodiment of the present disclosure may further include a speed calculation part 150 as illustrated in FIG. 2. The speed calculation part 150 may calculate the speed V1 of the first cable 210 based on the first moving-out position P1 detected by the first position detection part 121. Likewise, the speed calculation part 150 may calculate the speed V2 of the second cable 220 based on the second moving-out position P2 detected by the second position detection part 122.

Referring to FIG. 8, during the initial movement, the target load LT may be input through the load input part at S80. As described above, the target load LT may be input from the external device 30 through the device communication module 140, and may be input through the device input part 170 according to a user's manipulation.

In the embodiment of the present disclosure, when a preregistered load application condition is satisfied after the target load LT is input, the device control part 130 may control each of the first load supply module 111 and the second load supply module 112 to increase an exercise load to the target load LT.

Here, the device control part 130 may determine whether the load application condition is satisfied based on the combination of the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122.

More specifically, when the exercise preparation condition and the preparation completion condition are sequentially satisfied, the device control part 130 may increase the exercise load to the target load LT.

Referring to FIG. 8, when the target load LT is input at S80, the first position detection part 121 and the second position detection part 122 may respectively detect the first moving-out position P1 and the second moving-out position P2 of the first cable 210 and the second cable 220 at S81.

Here, when it is detected that the first cable 210 and the second cable 220 are moved out by a user pulling the handle bar at S82, the device control part 130 may recognize that the exercise preparation condition is satisfied. For example, when the first cable 210 and the second cable 220 are moved out 1 Cm or more, it may be recognized that the first cable 210 and the second cable 220 are moved out (see time t1 of FIG. 10).

For example, when the moving-out positions of the first cable 210 and the second cable 220 are maintained at specific positions for a period of preparation completion time, based on the moving-out positions detected by the first position detection part 121 and the second position detection part 122, the device control part 130 may determine that the preparation completion condition is satisfied at S87.

In the embodiment of the present disclosure, when the speed V1 of the first cable 210 and the speed V2 of the second cable 220 calculated by the speed calculation part 150 are maintained within a preset completion speed range for the period of preparation completion time, the device control part 130 may determine that the preparation completion condition is satisfied.

More specifically, the speed calculation part 150 may calculate the speed V1 of the first cable 210 and the speed V2 of the second cable 220 based on the first moving-out position P1 and the second moving-out position P2 at S83.

In addition, the device control part 130 may determine whether the speed V1 of the first cable 210 and the speed V2 of the second cable 220 are within the completion speed range at S84.

Referring to FIG. 10, when the first cable 210 and the second cable 220 are moved out by a user pulling the handle bar, the device control part 130 may recognize that the exercise preparation condition is satisfied at time t1 as described above.

In addition, when the user continues to pull the handle bar and takes a posture to prepare for exercise at time t2, the first moving-out position P1 and the second moving-out position P2 may be maintained at associated positions, respectively.

Here, the speed V1 of the first cable 210 and the speed V2 of the second cable 220 calculated by the speed calculation part 150 may increase at an initial state between time t1 and time t2, and may decrease gradually toward the position of the posture to prepare for exercise, and while the associated posture is maintained, the speed V1 of the first cable 210 and the speed V2 of the second cable 220 are maintained close to 0. Accordingly, in the embodiment of the present disclosure, when the completion speed range is preset to a range close to 0, it is recognized that a user has taken a posture to prepare for exercise.

Meanwhile, when the speed V1 of the first cable 210 and the speed V2 of the second cable 220 are maintained within the completion speed range for the period of preparation completion time at S87 while deviation between the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122 is maintained within the normal deviation DN at S85, the device control part 130 according to the embodiment of the present disclosure may determine that the preparation completion condition is satisfied.

When it is detected that the deviation between the first moving-out position P1 and the second moving-out position P2 is outside the normal deviation DN at S85, the device control part 130 may output an alarm for posture correction to a user at S86.

Here, the normal deviation DN may have the same size as the size of the normal deviation DN according to the above-described embodiment, but may be preset to other values suitable for posture correction.

On the other hand, when the period of preparation completion time has elapsed while the posture is maintained within the completion speed range, the device control part 130 may control each of the first load supply module 111 and the second load supply module 112 to increase an exercise load at time t3 of FIG. 10 at S80 so that the exercise load reaches a target load LT.

FIG. 10 is a graph illustrating a process in which a user performs exercise normally when the exercise load reaches the target load LT at time t4.

On the other hand, when it is detected that a user's posture is unbalanced while the exercise load is increasing at S80, the device control part 130 may stop the increase of the exercise load and may reduce the exercise load.

Referring to FIG. 9, in the process of increasing the exercise loads, the device control part 130 may determine whether deviation between the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122 exceeds the reference deviation DR at S90. Here, the size of the reference deviation DR at S90 and the size of the reference deviation DR in the above-described embodiment may be preset to be the same or different from each other.

In addition, when it is detected that the deviation exceeds the reference deviation DR at S90, the device control part 130 may reduce the exercise loads at S91. The device control part 130 may output an alarm for posture correction to a user at S92.

In the embodiment of the present disclosure, in the process of increasing an exercise load, that is, in the process of increasing the exercise load to the target load LT, when it is detected that a user's posture is unbalanced as described above, determination on whether the preparation completion condition is satisfied is initialized and is performed again. That is, the steps of S83 to S90 are performed.

On the other hand, when the exercise load reaches the target load LT at S93 while the deviation is maintained in a state not exceeding the reference deviation DR at S90, the device control part 130 may control exercise to be started at S94.

Here, in the process of exercise initiation at S94, the device control part 130 may output an exercise initiation guide to a user. For example, the actual initiation of a user's exercise may be performed before the target load LT is reached, and when a user's posture is unbalanced after the exercise initiation, entrance into S90 may be performed. In addition, after the target load LT is reached, as described above, load control may be applied under the target load LT.

According to the above configuration, after a user inputs the target load LT, a user may pull out the first cable 210 and the second cable 220 without separate manipulation, and only by a user taking a posture to prepare for exercise, an exercise load may be stably increased to a target load LT desired by the user, and exercise may be started.

Meanwhile, the muscle exercise device 10 according to the embodiment of the present disclosure may include a plurality of LED modules 160.

Referring to FIGS. 2 and 11, a plurality of LEDs is disposed along the longitudinal direction L on at least one portion of the opposite edge portions of the device body 110 in a width direction S thereof. In FIG. 11, the plurality of LED modules 160 is illustrated to be disposed along the longitudinal direction L at the opposite sides of the width direction S.

Here, the device control part 130 may control the blinking of the plurality of LED modules 160 in accordance with the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122.

For example, the plurality of LED modules 160 may include a plurality of first column LED modules 161 disposed at a first side in the longitudinal direction L from the center of the device body 110 in the longitudinal direction L thereof, and a plurality of second column LED modules 162 disposed at a second side from the center of the device body 110 in the longitudinal direction L thereof.

In addition, the device control part 130 may control the blinking of the plurality of first column LED modules 161 in accordance with the first moving-out position P1 detected by the first position detection part 121, and may control the blinking of the plurality of second column LED modules 162 in accordance with the second moving-out position P2 detected by the second position detection part 122.

For example, the device control part 130 may light some LED modules 160 among the plurality of LED modules 160 so that the number of the some LED modules 160 corresponds to the moving-out positions in any one direction (in an LS or RS direction of FIG. 11) from the center of the device body in the longitudinal direction L.

More specifically, based on the first moving-out position P1 detected by the first position detection part 121, the device control part 130 may sequentially light the LED modules as much as the moving-out length from the first column LED modules 161 positioned at the center of the device body 110 in the longitudinal direction L, and may sequentially turn off the LED modules in the opposite direction when the cables are moved in, thereby providing an animation effect in accordance with the inward and outward movements of the first cable 210. The device control part 130 may control the second column LED modules 162 to provide an animation effect in cooperation with the second position detection part 122.

Meanwhile, the muscle exercise device 10 according to the embodiment of the present disclosure may include a plurality of wheel modules 182 as illustrated in FIG. 12. The plurality of wheel modules 182 may be installed on the lower surface of the device body 110. In the present disclosure, four wheel modules 182 may be installed in pairs by being spaced apart from each other in the width direction S of the device body 110 at the opposite sides of the device body 110 in the longitudinal direction thereof.

Each of the wheel modules 182 according to the embodiment of the present disclosure may be installed to be moved in and out of the device body 110. Accordingly, when a user moves the device body 110, the wheel modules 182 may be moved out of the device body 110 to provide convenience of the movement of the device body 110.

On the other hand, when exercise is performed in a state in which the device body 110 is positioned at a specific position, the wheel modules 182 may be moved in the device body 110 so that the exercise can be more safely performed.

Here, the wheel modules 182 may be maintained to be pressed by elastic members (not shown) from moving-in positions of the wheel modules 182 to the moving-out positions thereof so that the wheel modules 182 can be easily moved out of the device body 110. On the other hand, the moving-in positions of the wheel modules 182 may be preferably maintained by a locking structure (not shown). Accordingly, for the movement of the muscle exercise device, a user may release the locking structure to move the wheel modules 182 out of the device body, and then may move the muscle exercise device.

However, even when the locking structure is released, the elastic force of the elastic members may be overcome due to the weight of the device body 110, and thus it may be recognized that the device body 110 is recognized as being in contact with a floor. That is, the wheel modules 182 may be in a state capable of being moved out from the device body 110.

In this state, when a user steps on the device body 110, the device body 110 may move due to the wheel modules 182 in contact with the floor, which may cause an accident.

Accordingly, the muscle exercise device 10 according to the embodiment of the present disclosure may include a wheel detection part as illustrated in FIG. 2.

For example, the wheel detection part may detect whether the wheel modules 182 is in a state capable of being moved out. That is, the wheel detection part may detect whether the wheel modules 182 is in the state capable of being moved out due to the release of the locking structure instead of due to whether the wheel modules 182 are moved out.

For example, whether the locking structure holds the wheel modules 182 may be detected by using a contact sensor. For another example, whether the wheel modules 182 are not completely moved in to be held in the locking structure and are moved out of the device body 110 more than the complete moving-in state may be detected by an infrared sensor.

Here, when it is detected by the wheel detection part that at least one of the plurality of the wheel modules 182 is in a state capable of being moved out of the device body 110, the device control part 130 may light the plurality of LED modules 160 in a preset light emitting color or a preset light emitting pattern so that a user can recognize the same.

For example, in the case of lighting in cooperation with the outward movement of the first cable 210 and the second cable 220 as described above, the LED modules may be lit in a green color, and when the outward movements of the wheel modules 182 are detected, the LED modules may be lit in a red color. In addition, even when the LED modules are lit in red colors, the LED modules may repeat blinking or may have an animation effect so that a user can recognize the light more easily.

Meanwhile, the device control part 130 according to the embodiment of the present disclosure may control the first load supply module 111 and the second load supply module 112 according to any one of the plurality of exercise levels.

Here, the exercise level may include information about an exercise load for each different level and a cable speed for each level. For example, three exercise levels may be applied, and as an exercise level increases, an exercise load for each level and a cable speed for each level may be preset to increase. For example, an exercise level may be registered to the external device 30.

When the speed V1 of the first cable 210 and the speed V2 of the second cable 220 calculated by the speed calculation part 150 are faster than the speeds of cables for each level of the present exercise level, the device control part 130 may control the first load supply module 111 and the second load supply module 112 so that the exercise loads of the first load supply module 111 and the second load supply module 112 are reduced when the first cable 210 and the second cable 220 are moved in.

That is, when the first cable 210 and the second cable 220 are moved into the device body 110 in a case in which a user is exercising faster than a preset exercise level, the first cable 210 and the second cable 220 may be moved into the device body 110 at higher speeds due to exercise loads.

This situation may cause a user to have an unbalanced posture or to fall down. Accordingly, when the first cable 210 and the second cable 220 are moved in, exercise loads may be reduced to decrease moving-in speeds thereof.

In addition, when the speeds of the cables 210 and 220 calculated by the speed calculation part 150 are faster than the speeds of the cables of each level of the present exercise level, the device control part 130 may perform an action to change an exercise level.

For example, the device control part 130 may transmit a level changeable signal through the device communication module 140 to the external device 30. In addition, the external device 30 may display a plurality of exercise levels on a screen and inform that the level can be changed, allowing a user to select a different exercise level.

When a user changes an exercise level through the external device 30, the external device 30 may transmit the level change request signal to the device control part 130, and the device control part 130 receiving the level change request signal from the external device 30 may control the first load supply module 111 and the second load supply module 112 based on a changed exercise level.

Here, an exercise load for each level of the exercise level of a first stage among the plurality of exercise levels may be registered as the target load LT. In addition, when the exercise load of the exercise level of the first stage is preset as the target load LT, an exercise load with a value greater than the target load LT may be registered step by step as an exercise level of a next stage.

In the embodiment described above, the case of the exercise type in which with the first cable 210 and the second cable 220 connected respectively to the opposite sides of the handle bar, the first cable 210 and the second cable 220 are moved in and out in the same directions has been described as an example.

On the other hand, in another embodiment of the present disclosure, it is possible to realize the movement of an exercise type in which with a D-type grip connected to each of the first cable 210 and the second cable 220, the first cable 210 and the second cable 220 are moved in and out in different directions. In addition, it is possible to exercise by using a D-type grip of only one of the first wire 210 and the second wire 220

Accordingly, a user may select the type of exercise before starting the exercise, and a case in which the device control part 130 controls exercise by using deviation between the first moving-out position P1 and the second moving-out position P2 detected by the first position detection part 121 and the second position detection part 122 may be applied only to an exercise type in which the first cable 210 and the second cable 220 are moved in and out in the same directions.

On the other hand, blinking control of the plurality of LED modules 160 may be applied to all of the above-described exercise types.

Although the embodiments of the present disclosure have been described above with reference to the accompanying drawings, the muscle exercise device of the present disclosure is not limited to the above embodiments, but may be manufactured in various different forms. Those skilled in the technical field to which the present disclosure belongs will be able to understand that the muscle exercise device of the present disclosure may be configured in other specific forms without changing the technical idea or essential characteristics of the present disclosure. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
