FIELDThe present disclosure relates to the technical field of fitness equipment, and more particularly, to a smart wall pulley for fitness.
BACKGROUNDA smart wall pulley for fitness can help people in exercising muscles, body-shaping, and effectively improving physical quality, therefore it is highly popular with the majority of fitness enthusiasts. A common smart wall pulley is composed of two handles and an elastic rope. Since the smart wall pulley for fitness has the characteristics of small floor space and portability, it can help an exerciser to do all-around exercises any time any where, including for example a strength exercise, a flexibility exercise, a pulling exercise, a stretching exercise and the like, and therefore it is an indoor fitness equipment having a very high degree of freedom. However, an existing smart wall pulley for fitness cannot perform data statistics for the exercise process of the exerciser while the exerciser is doing exercises, thus it has a low degree of intelligence. Furthermore, when the length of the elastic rope is adjusted, an adjusting buckle applies a shear force on the elastic rope, which would easily cause the elastic rope to be broken after a long-term use.
SUMMARYThe present disclosure aims to solve at least one of technical problems existing in the prior art.
A smart wall pulley for fitness according to an embodiment of the present disclosure includes an elastic rope, a motion sensing detection device, a fixed pulley assembly, and an adjuster. The elastic rope is elastic. The motion sensing detection device is provided at one end of the elastic rope. A battery, a circuit board and a tension sensor are provided within the motion sensing detection device. The battery and the tension sensor are electrically connected to the circuit board. The adjuster includes a shell and a winding post located within the shell. The other end of the elastic rope passes into the shell, then is wound around the winding post, then passes out from the shell. The other end of the elastic rope is fixedly connected to the shell after being wound around the fixed pulley assembly.
In the smart wall pulley for fitness according to the embodiment of the present disclosure, the winding post is provided within the shell and the elastic rope is wound around the winding post. Therefore, when a user delivers a part of the elastic rope into the shell of the adjuster, the elastic rope may be moved relative to the winding post. Further, Due to the limited space in the shell, another part of the elastic rope will be extruded out of the shell under the drive of the elastic rope, therefore the distance between the adjuster and an end of the elastic rope can be adjusted and thus the length of the smart wall pulley can be adjusted. In addition, when the smart wall pulley is used, both the two parts of the elastic rope may each are subjected to a pulling force, and as the pulling force increases, the elastic rope applies a larger winding force to the winding post, such that the winding post can fix the elastic rope. In addition, by providing the tension sensor at one end of the elastic rope, a pulling force bore by the elastic rope can be detected, therefore a user's training condition can be monitored and recorded, thereby facilitating the user to perform a detailed planning on the training.
The above and/or additional aspects and advantages of the present disclosure will become apparent and readily appreciated from the description of embodiments in conjunction with the following figures, in which:

DETAILED DESCRIPTIONEmbodiments of the present disclosure will be described in detail below, examples of which are shown in the drawings in which the same or similar reference numerals denote same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the figures are exemplary, merely used to explain the present disclosure, and cannot be construed as limiting the present disclosure.
A smart wall pulley 100 for fitness according to embodiments of the present disclosure is described below with reference to
As shown in
Specifically, the elastic rope 110 is elastic, and the motion sensing detection device 10 is provided at one end of the elastic rope 110. A battery 121, a circuit board 16 and a tension sensor 124 are provided within the motion sensing detection device 10, and the battery 121 and the tension sensor 124 are electrically connected to the circuit board 16. It should be noted that, the tension sensor 124 may be configured to detect a pulling force the elastic rope 110 is bearing, and transmits detected data to an electric component on the circuit board 16. And then, the corresponding electric component converts, through data conversion, information detected by the tension sensor 124 into a form of information that can be read by a user, such that the user can know the pulling force being applied to the smart wall pulley 100. In addition, the tension sensor 124 may be further configured to adjust an overall length of the smart wall pulley 100 in consideration of elastic resistance of the elastic rope 110, such that the smart wall pulley 100 can satisfy needs of different users for different lengths. In addition, it should be noted that the battery 121 may supply power to the tension sensor 124 and electric components on the circuit board 16.
As shown in
It can be understood that, the adjuster 140 can divide the elastic rope 110 into two parts. Here, one part of the elastic rope is from the one end of the elastic rope 110 to the adjuster 140, and is provided with the motion sensing detection device 10 thereon. During a physical training, a user can apply a pulling force to the elastic rope 110 by pulling the motion sensing detection device 10, and at the same time, the motion sensing detection device 10 can detect the magnitude of the pulling force. The other part of the elastic rope is from the other end of the elastic rope 110 to the adjuster 140. On the other part, the elastic rope 110 is wound around the fixed pulley assembly 130, and the user can apply a pulling force to the elastic rope 110 by pulling the fixed pulley assembly 130 during the physical training.
When the smart wall pulley 100 is used, both two parts of the elastic rope 110 may each are subjected to a pulling force. Under the action of the pulling force, the elastic rope 110 is wound around the winding post 142, and as the pulling force increases, the elastic rope 110 applies a larger winding force to the winding post 142, such that a relative position between the elastic rope 110 and the winding post 142 cannot be easily changed and the winding post 142 can play a role of fixing the elastic rope 110. When the smart wall pulley 100 is in a natural state, the elastic rope 110 is not subjected to an external force and can be wound around the winding post 142 in a natural state, and there is no acting force between the elastic rope 110 and the winding post 142. When a user delivers a part of the elastic rope 110 into the shell 141 of the adjuster 140, the elastic rope 110 can be moved relative to the winding post 142. Due to the limited space in the shell 141, another part of the elastic rope 110 will be extruded out of the shell 141 under the driving of the elastic rope 110. Thus, a distance between the adjuster 140 and an end of the elastic rope 110 can be adjusted, thereby the length of the smart wall pulley 100 can be adjusted.
Of course, it can also be understood that, when the smart wall pulley 100 is in a natural state, the user can drive the adjuster 140 to move along the elastic rope 110 by applying a force to the elastic rope 110 on one side of the adjuster 140. At this point, the elastic rope 110 can be moved around the winding post 142, and both a length of the elastic rope 110 located on one side of the adjuster 140 and a length of the elastic rope 110 located on the other side of the adjuster 140 can be changed, that is, the overall length of the smart wall pulley 100 may be adjusted at this time.
In the smart wall pulley 100 for fitness according to the embodiment of the present disclosure, the winding post 142 is provided within the shell 141 and the elastic rope 110 is wound around the winding post 142. Therefore, when the user delivers a part of the elastic rope 110 into the shell 141 of the adjuster 140, the elastic rope 110 may be moved relative to the winding post 142. Further, Due to the limited space in the shell 141, another part of the elastic rope 110 will be extruded out of the shell 141 under the driving of the elastic rope 110, therefore the distance between the adjuster 140 and an end of the elastic rope 110 can be adjusted and thus the length of the smart wall pulley 100 can be adjusted. In addition, when the smart wall pulley 100 is used, both the two parts of the elastic rope 110 may each are subjected to a pulling force, and as the pulling force increases, the elastic rope applies a larger winding force to the winding post, such that the winding post can fix the elastic rope 110. In addition, by providing the tension sensor 124 at one end of the elastic rope 110, a pulling force bore by the elastic rope 110 can be detected, therefore a user's training condition can be monitored and recorded, thereby facilitating the user to perform a detailed planning on the training.
As shown in
According to some embodiments of the present disclosure, as shown in
As shown in
In some embodiments, in order to facilitate fixing the upper shell 143 and the lower shell 144 together, as shown in
It should be noted that, as long as the upper shell 143 and the lower shell 144 can be fixedly connected together, the fixing manner of the upper shell 143 and the lower shell 144 is not limited the above example. For example, in some examples, as shown in
According to some embodiments of the present disclosure, as shown in
As shown in
In order to conveniently connect the protective shell 11 and the connecting shell 125 together, in the example as shown in
Further, in order to prevent the protrusion 1251 from disengaging from the groove 1264, as shown in
The adjuster 140 further includes a winder. The elastic rope 110 is wound in the winder. The other end of the elastic rope 110 passes into the shell 141, passes out from the shell 141 after being wound in the winder, then is wound around the fixed pulley assembly 130, and then is fixedly connected to the shell 141.
The winder is adapted to control the elastic rope 110 of the smart wall pulley 100 to be received into the winder or to be released from the winder to adjust a natural length of the smart wall pulley 100. It should be noted that, the winder may receive or release the elastic rope 110, and when it needs to adjust the overall length of the smart wall pulley 100, the elastic rope 110 may be released or received by controlling the winder, so that the overall length of the smart wall pulley 100 may be adjusted. Thus, it can not only simplify the structure of the adjuster 140, but also prevent the elastic rope 110 from wearing under the action of any clamping member, such that the elastic rope 110 can be protected and the service life of the elastic rope 110 can be extended. In addition, the winder may be selected as having a grade adjustment structure. For example, the winder may release or receive the elastic rope 110 according to a predetermined length ratio, that is, when the winder adjusts the length of the elastic rope 110, it releases or receives a same length of the elastic rope 110 per level.
According to some embodiments of the present disclosure, as shown in
To facilitate mounting the elastic rope 110 inside the shell 141, in some embodiments, the shell 141 includes an upper shell 143 and a lower shell 144. The upper shell 143 is connected to the lower shell 144 to define an installation cavity 1443. The winder may be disposed within the installation cavity 1443. Thus, when the winder is mounted inside the shell 141, the winder may be first placed in the lower shell 144, then the upper shell 143 is arranged on the lower shell, and then the upper shell 143 and the lower shell 144 are fixedly connected to each other, such that the winder may be fixed inside the shell 141.
Referring to
As shown in
As shown in
For example, each of the ratchet 432 and the gear 431 has a plurality of teeth arranged at intervals. When the toggle handle 433 is in an initial state, at least one tooth of the ratchet 432 is located between and abuts against two adjacent teeth of the gear 431, and at least one tooth of the gear 431 is located between and abuts against two adjacent teeth of the ratchet 432. In this way, the ratchet 432 and the gear 431 may restrict each other. At this point, the winding post cannot rotate either, because the gear 431 rotates coaxially with the winding post 142. The toggle handle 433 is configured to disengage the gear 431 from the ratchet 432 or disengage the ratchet 432 from the gear 431. In this way, the winding post can be rotated so as to adjust the length of the smart wall pulley 100. With the arrangement of the gear 431 and the ratchet 432, a stepwise adjustment of the smart wall pulley 100 is achieved. Of course, in other embodiments, the ratchet gear assembly 43 may further include a pawl or the like to achieve a stepless adjustment of the ratchet gear assembly 43. In the description of the present disclosure, the term “a plurality of” means two or more.
In some embodiments, the ratchet gear assembly 43 further includes a restoration member 434 connected to the ratchet 432, so as to drive the ratchet 432 to mesh with the gear 431 constantly. In this way, it may be not necessary for a user to, after adjusting the length of the smart wall pulley 100, control the toggle handle 433 to be reset by himself, thereby reducing operation steps of the user. For example, the restoration member 434 may be provided with a mounting post. The restoration member 434 may be connected to the mounting post to drive the ratchet 432 to mesh with the gear 431 constantly.
According to an embodiment of the present disclosure, as shown in
The restoration member 434 is a torsion spring with which the connecting post 50 is sleeved. One end of the torsion spring abuts against the shell 141, and the other end of the torsion spring abuts against the toggle handle 433. By the arrangement of the torsion spring, the toggle handle 433 can restore slowly under the acting force of the torsion spring, thereby reducing operation steps of adjusting the smart wall pulley 100 performed by a user. For example, the torsion spring may have a mounting part 4341 extending towards the shell 141, the shell 141 may have a mounting hole or a mounting groove, and the mounting part 4341 may extend into the mounting hole or the mounting groove to improve the reliability of mounting the torsion spring to the shell 141.
For example, when the toggle handle 433 is in the initial state, referring to
In some embodiments, the toggle handle 433 includes a connecting part 4331 and a toggling part 4332 connected to the connecting part 4331. The connecting part 4331 is connected to the ratchet 432. The toggling part 4332 is in a shape of a long strip so as to facilitate the toggling by the user. Further, the connecting part 4331 can be in a circular shape which is different from that of the ratchet 432, thereby facilitating user operation.
For example, the smart wall pulley 100 may be provided with a pull ring 90 at each of its two ends. The user may grasp the pull ring 90 at one end by his/her hand, and may tie the pull ring 90 at the other end on his/her ankle to perform physical exercises. Alternatively, the user may grasp the pull ring 90 at one end by his/her hand, and mount the pull ring 90 at the other end to an object with a heavier weight to perform physical exercises. Of course, the smart wall pulley 100 may have a plurality of use ways, which are not limited herein.
In some examples, as shown in
According to an embodiment of the present disclosure, the ratchet 432 and the toggle handle 433 are integral with each other, so as to simplify the steps, facilitate the assembly, improve the assembly efficiency, and improve structure stability and reliability. Alternatively, the ratchet 432 may be connected to the toggle handle 433 by a screw. Any of the above manners can effectively ensure the movement consistency of the ratchet 432 and the toggle handle 433. Of course, there may be a plurality of manners for the fitting of the ratchet 432 and the toggle handle 433, which are not limited herein.
In some embodiments, referring to
The upper shell 143 may have a positioning groove (not shown), and the other end of the winding post 142 is located in the positioning groove, such that the reliability of the connection between the winding post 142 and the upper shell 143 can be improved. Of course, the upper shell 143 or the lower shell 144 may also include a positioning post 4111 sleeved with the winding post 142. In this way, on one hand, positioning and mounting may be facilitated and the connection is stable. On the other hand, when the winding post 142 rotates, the positioning post 4111 may prevent the winding post 142 from displacing in an axial direction, which would otherwise cause the winding post 142 to be disengaged from the upper shell 143.
In some embodiments, a plurality of screw posts 4112 are provided in the upper shell 143, and extend towards the lower shell 144. The upper shell 143 and the lower shell 144 may be connected by screws which are connected to the screw posts 4112. For example, the lower shell 144 may also be provided with a plurality of screw posts 4112, so as to further improve the installation reliability. The screws may pass into the screw posts 4112 of the upper shell 143 and the screw posts 4112 of the lower shell 144 to fix the upper shell 143 and the lower shell 144 together. Alternatively, the upper shell 143 and the lower shell 144 are connected in a snap-fit manner. Of course, in other embodiments, the upper shell 143 and the lower shell 144 may be mounted to each other by a plurality of manners, which are not limited herein.
