Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method and an apparatus of counting steps for a treadmill, and more particularly to a method and an apparatus of measuring a step count of an exerciser on a treadmill by an instant load.

2. Description of the Related Art

When users are doing exercises, they usually keep track of the time and quantity of the exercises and the exercise time is generally measured by a regular stopwatch. However, it is not objective to evaluate the quantity of exercise per day simply by the exercise time, and it is not easy to evaluate the quantity of exercise by the exercise time either, because every user may do exercise in different ways. Therefore, it is more objective to measure the quantity and time of exercise for the same kind of exercises.

As to the common exercises: jogging and walking, a general pedometer available in the market can be used to count the steps of an exerciser's walking or jogging, so as to let exercisers know about their physical conditions and the quantity of exercises.

However, it is necessary to wear a pedometer on an exerciser's body for counting the steps of walking and jogging, and thus it causes inconvenience to exercisers. Furthermore, an exerciser may not feel comfortable or get used to the wearing of a pedometer while doing exercises, and thus the prior art requires improvements.

For general treadmills, users can select their desired exercise modes (including exercise time, exercise type, and exercise speed, etc), but users still cannot be aware of the quantity of their exercise.

SUMMARY OF THE INVENTION

In view of the shortcomings of the prior art, the inventor of the invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally invented a method and an apparatus of counting steps for treadmill in accordance with the present invention.

Therefore, it is a primary objective of the present invention to provide a feasible solution and overcome the foregoing problems by providing a method and an apparatus of counting steps for a treadmill, such that exercisers no longer need to wear a pedometer, but directly read the step count of their walking or jogging from the treadmill. When exercisers are using the treadmill, they can control the quantity of exercises on their own.

A secondary objective of the present invention is to provide a procedure of determining the load of a treadmill, such that the motor will stop operating, either there is no load in predetermined discrete time or during continuous load of the treadmill.

To achieve the foregoing objectives, the present invention provides a method of counting steps for a treadmill that comprises the steps of using an existing treadmill with a motor and a treadmill belt as a basis, and the motor drives the treadmill belt to operate, and the treadmill belt is provided for a user to pedal; measuring a load exerted on the treadmill, and detecting the number of times of an instant load of the motor caused by applying a force by an exerciser's legs for each time of the exercise, and counting the steps performed by the exerciser's exercise, and displaying the step count of the user's legs.

The present invention also provides a treadmill that comprises:

a treadmill body, having a base, a motor and a treadmill belt installed at the base, and the motor is installed at a side of the base and has two tracks, and the treadmill belt is wound circularly between the two tracks of the base, and the treadmill belt is driven to rotate by the motor;

a load detection unit, for detecting a load exerted on the motor and recording the number of instant loads of the motor in the same time; and

a display unit, electrically coupled to the load detection unit, for outputting the number of loads of the motor.

The present invention also provides a load determination step that measures a load exerted on said treadmill, and separately defines a continuous load and a discrete load;

a continuous load is exerted onto the motor by a user, such that the motor will be controlled to stop operating, if the load is determined as a continuous load; and

a discrete load, exerted onto the motor, such that a predetermined discrete time will be used to determine whether or not the user stops moving if the load is determined as a discrete load; the motor will keep on operating if another load shows up in the motor within a discrete time; and the motor will be controlled to stop operating if no more load is in the motor within a discrete time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 for a method of counting steps for a treadmill in accordance with this embodiment, the method comprises the steps of using an existing treadmill with a motor and a treadmill belt as a basis (and the treadmill, motor, and treadmill belt will be described in the structure of a treadmill) and the motor drives the treadmill belt to operate, and the treadmill belt is provided for a user to pedal. The user just follows the general sequence of exercising on the treadmill directly for counting the steps.

In FIG. 1, the motor will cause an intermittent load when a user is exercising his/her legs on a treadmill. The load exerted on the treadmill is measured and the number of instant loads caused by the user applying a force by the legs on the treadmill belt of the treadmill is detected when the user is exercising for each time, and the number of leg exercises is calculated when the user is exercising.

The number of loads is defined as a step count of a user stepping on the treadmill belt. The step count in a numeric form is outputted on a display panel.

The method of measuring the load exerted on the treadmill is one selected from the collection of a voltage feedback of the motor, a current feedback of the motor and an optical disk installed in the motor.

Therefore, users need not to wear a pedometer while doing exercise, but they can know about the step count directly from the treadmill while jogging on the treadmill. The invention not only provides convenience and avoids discomfort, but also saves the trouble of wearing a pedometer while doing exercises. In the meantime, it is not necessary for users to specially learn how to operate the treadmill or preset the treadmill, and thus the operation is very convenient.

Referring to FIGS. 2 and 3, the present invention also provides a treadmill, comprising: a treadmill body 1, a load detection unit, and a display unit 3.

The treadmill body 1 has a base 11, a rail 12 connected to the base 11, and an operating panel 13 connected to the rail 12 (for installing a load detection unit). The base 11 has a motor 2 and a treadmill belt 21. The motor 2 is installed on a side of the base 11, and the base 11 has two tracks 111, and an axle 112 is disposed separately at the front and the rear of the two tracks 111. The treadmill belt 21 is wound circularly between the two tracks 111 of the base 11 and also wound around the axle 112 of the two tracks 111, and the treadmill belt 21 is driven to rotate by the motor 2.

The load detection unit (this embodiment adopts a current detection circuit of the motor as a load detection unit which is not shown in the figure) is provided for detecting a load exerted on the motor 2, and recording the number of instant loads of the motor 2 at the same time.

The display unit 3 is electrically connected to the load detection unit and outputs the number of loads of the motor 2. The display unit 3 of this embodiment is a screen installed at the operating panel 13, and the load of the motor 2 is displayed in a numeric form on the screen.

The load detection unit is one selected from the collection of a voltage feedback detector of the motor, a current feedback detector of the motor, and an optical disk installed at the motor for detecting the load of the motor.

Referring to FIGS. 3 and 4, the invention further comprises a load determination step that measures the load exerted on the treadmill and defines a continuous load and a discrete load.

A continuous load is exerted on a motor by a user, such that the motor will be controlled to stop operating, if a load is determined as a continuous load; a discrete load is exerted onto the motor, such that a predetermined discrete time will be used to determine whether or not the user stops moving if a load is determined as a discrete load; the motor will keep on operating if another load shows up in the motor within a discrete time; and the motor will be controlled to stop operating if no more load is in the motor within a discrete time.

If a load is determined as a continuous load, it shows that the user has stopped jogging and stands on the treadmill belt or the treadmill belt gets stuck (by the user's bottom of a trouser leg, a shoelace or the user's body) and thus the motor 2 will stop immediately to prevent accidents.

If a load is determined as a discrete load, it shows that the user is using the treadmill. If the user stops jogging at this point, then there will be no more load within the suspended time and it shows that the user has left the treadmill, and thus preventing children or other people from standing on the treadmill suddenly and also preventing accidents.
