Description

BACKGROUND OF THE INVENTION

[0001]1. Field of the Invention

[0002]The present invention relates generally to exercise and fitness, and more particularly, to an exercise apparatus.

[0003]2. Description of the Related Art

[0004]A conventional exercise apparatus is composed of a counterweight device and an operating device connected with the counterweight device. The counterweight device includes a plurality of weight pieces whose number is adjustable subject to the requirement while a user strengthens his/her muscles in such a way that a proper load of weight can be provided. In other words, the exercise apparatus can help the user strengthen the muscles for different degrees by means of different number of the counterweigh blocks.

[0005]However, people have different physical stamina and require different degrees of muscular strengthening, such that it is not easy to infer the outcome of the user's muscle strengthening. Generally speaking, the muscle strengthening needs more accurate data for procurement of exercise amount and calorie expenditure. For the prior art, the user may though feel that much exercise is taken but fails to know the exact data of performance of the muscular strengthening, such that it is deficient for inconvenient operation to need improvement.

SUMMARY OF THE INVENTION

[0006]The primary objective of the present invention is to provide an exercise apparatus, which can come up with the exact data of performance of the user's muscular strengthening to be convenient for the user.

[0007]The foregoing objective of the present invention is attained by the exercise apparatus composed of a counterweight device, a pulley assembly, a pulley sensor, an operating device, and a control device. The counterweight device includes a frame, a plurality of weight pieces mounted to the frame, and a plurality of electronic switches mounted to the frame for detecting the number of the weight pieces that are moved. The pulley assembly includes at least one pulley mounted to the frame; and a transmission member mounted to the pulley and connected with the weight pieces. The pulley sensor is mounted to the frame for sensing the status of the pulley. The operating device is connected with the transmission member for driving the pulley assembly to move the weight pieces. The control device is electrically connected with the electronic switches and the pulley sensor for calculating, displaying, and recording data of the user's exercise performance.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0014]Referring to FIGS. 1-4, an exercise apparatus 10 constructed according to a preferred embodiment of the present invention is composed of a counterweight device 20, a pulley assembly 30, a pulley sensor 40, an operating device 50, and a control device 60.

[0015]The counterweight device 20 includes a frame 22, a plurality of weight pieces 24 mounted to the frame 22, and a plurality of electronic switches 26 mounted to the frame 22. Each of the weight pieces 24 has a magnetic portion 241. Each of the electronic switches 26 is a photoelectric switch or a reed switch, which is taken in this embodiment as an example only rather than a limitation. The magnetic portions 241 can magnetically activate the electronic switches 26 for detecting the number of the weight pieces 24 that are moved. When the electronic switches 26 detect one of the magnetic portions 241, the electronic switch 26 is triggered.

[0016]The pulley assembly 30 includes a plurality of pulleys 32 and a transmission member 34. The pulleys 32 are mounted to the frame 22. The transmission member 34 is mounted to the pulleys 32 and connected with the weight pieces 24. The transmission member 34 is a belt or a cable wire, which is taken in this embodiment as an example only rather than a limitation.

[0017]The pulley sensor 40 is mounted to the frame 22 and located at one of the pulleys 32 for sensing the status of the pulleys 32. The pulley sensor 40 is a pressure sensor, a photoelectric sensor, or a Hall sensor, which is taken in this embodiment as an example only rather than a limitation.

[0018]The operating device 50 is connected with the transmission member 34 for the user to operate for strengthening the user's muscles. While the operating device 50 is operated, the transmission member 34 is drawn to enable the pulley assembly 30 to drive the movement of the weight pieces 24.

[0019]The control device 60 is electrically connected with the electronic switches 26 and the pulley sensor 40. The control device 60 includes a processor 62, a display panel 64, and a memory module 66. The processor 62 is electrically connected with the electronic switches 26 and the pulley sensor 40, for identifying the number of the moved weight pieces 24 according to the number of the triggered electronic switches and then identifying the status of the pulleys 32 according to output signals of the pulley sensor 40 for inferring data of performance of the user's muscle strengthening. The data include at least one of the information, like load of weight, exercise frequency, exercise time, and calorie expenditure. The display panel 64 is electrically connected with the processor 62 for displaying the data. The memory module 66 is electrically connected with the processor 62 for recording the data.

[0020]Referring to FIGS. 5-6, a method based on the exercise apparatus 10 for inferring the data of performance of the user's muscle strengthening includes the following steps.

[0021]a) Sense the movement of the pulleys 32 by the pulley sensor 40. If the pulleys 32 remain still, repeat this step to identify whether the user has operated the exercise apparatus 10. If the pulleys 32 are moved, indicating that the user begins to pull the transmission member 34 for operating the exercise apparatus, proceed to the next step.

[0022]b) Detect the magnetic portions 241 by the electronic switches 26. The processor 62 acquires the number of the moved weight pieces 24 according to the number of the triggered electronic switches.

[0023]c) The processor 62 acquires the load of weight according to the number of the moved weight pieces 24 to calculate the exercise time and the calorie expenditure.

[0024]d) Detect by means of the pulley sensor 40 as to whether the pulleys 32 are rotated counterclockwise. If the pulleys 32 have not been rotated counterclockwise, indicating that the user has not finished pulling the weight pieces 24, repeat this step. If the pulleys 32 are rotated counterclockwise, indicating that the user has finished pulling the weight pieces 24 to reinstate the weight pieces 24, proceed to the next step.

[0025]e) Accumulate the exercise frequency.

[0026]f) Sense by the pulley sensor 40 as to whether the pulleys are rotated clockwise. If the pulleys 32 are rotated clockwise, indicating that the weight pieces 24 are pulled again, proceed back to the step b). If the pulleys 32 have not been rotated clockwise, indicating that the weight pieces 24 have not been reinstated, proceed back to the next step.

[0027]g) Sense by the pulley sensor 40 as to whether the pulleys 32 stop rotation. If the pulleys 32 do not stop rotation, proceed back to the step f). If the pulleys 32 stop rotation, indicating that the user stops operating the exercise apparatus 10, the processor 62 stops counting the time.

[0028]In conclusion, the exercise apparatus 10 of the present invention can come up with more accurate data, like the load of weight, the exercise frequency, the exercise time, and the calorie expenditure, to further enable the user to know the performance of the muscle strengthening.

[0029]Although the present invention has been described with respect to a specific preferred embodiment thereof, it is no way limited to the details of the illustrated structures but changes and modifications may be made within the scope of the appended claims.
