Description

Fitness device function conversion device

This creation is a kind of fitness machine, especially a function conversion device of an exercise machine.

Due to the increasing emphasis on physical health and the continuous improvement of living standards, the use of sports equipment has become more and more extensive, and a large number of exercise equipments for exercising different parts of the human body have appeared. For example, the kick trainer, the traditional kick trainer directly passes the fixed pulley. Steering and transmitting force are carried out, and the moving arm does not change during rotation, and the user's need to change the force when kicking the leg and closing the leg cannot be satisfied.

In view of the above, in order to solve the above-mentioned shortcomings, the present invention provides a function conversion device for a fitness device whose leg strength and leg strength can be changed, including:

An eccentric wheel set consisting of a lower cam having an equal radius and an upper cam having a contoured gradient, the upper cam being fixedly mounted on a top surface of the lower cam, the lower cam and the upper cam being coaxial cams; a front belt connected at one end a heavy block and the other end of which is connected to the lower cam below the eccentric wheel set; a rear belt, one end connected to a seat cushion carriage and the other end connected to the upper cam on the eccentric wheel set; a main rotating shaft, the eccentric wheel The central portion of the group is rotatably sleeved on the main shaft.

According to the above technical features, the following effects can be achieved:

1. Since the eccentric wheel set is composed of a contoured upper cam and a lower radius lower cam, the upper cam is fixedly mounted on the top surface of the lower cam, and the contour of the upper cam is changed, directly affecting the length of the moving arm during the movement, The rear belt on the upper cam is connected with the seat cushion frame, and the athlete sits on the seat cushion, and the two feet are stepped on the foot pedal, so that when the two legs are in the process of switching between the leg extension and the flexion leg, the movement is smoother, smoother and safer.

In combination with the above technical features, the main functions of the function conversion device of the present exercise machine will be clearly presented in the following embodiments.

Please refer to the first to third figures. The preferred embodiment of the present invention is a function conversion device for an exercise machine, including:

a main frame (1), a pedal (2), a cushion carriage (3), a guide rod (4), a positioning plate (5), a main rotating shaft (6), and a positioning shaft (7) An eccentric wheel set (8), a front belt (9), a rear belt (10), a weight group (20), and a weight frame (30).

The foot pedal (2) is mounted at one end of the main frame (1), the guiding rod (4) is mounted in the middle of the main frame (1), and the seat cushion carriage (3) is slidably connected to the guiding rod (4) The positioning plate (5) is fixed on the main frame (1), the lower end of the main rotating shaft (6) is vertically fixed on the main frame (1), and the middle part of the eccentric wheel set (8) is rotatable Attached to the main rotating shaft (6), the positioning shaft (7) is fixed at the bottom of the eccentric wheel set (8), and the weight group (20) is mounted on the weight frame (30), the weight frame (30) Mounted on one side of the main frame (1).

The eccentric wheel set (8) consists of a lower cam (81) of equal radius and an upper cam (82) of contoured gradation. The upper cam (82) is fixedly mounted on a top surface of the lower cam (81), the lower cam (81) and the upper cam (82) are coaxial cams; one end of the front belt (9) is connected to the weight group ( 20) and the other end thereof is connected to the lower cam (81) below the eccentric wheel set (8), one end of the rear belt (10) is connected to the seat cushion carriage (3) and the other end thereof is connected to the eccentric wheel set (8) The upper cam (82) above.

The working principle of this creation is as follows:

The lower cam (81) of the eccentric wheel set (8) and the upper cam (82) belong to a coaxial cam, and rotate at the same speed; the lower cam of the lower radius (81) ensures a constant load, and the upper contour changes. The cam (82) constantly changes the resistance torque during the movement. The positioning shaft (7) on the eccentric wheel set (8) acts as a limit.

Please refer to the third figure to the fifth figure, the eighth figure to the tenth figure, and the user sits on the seat cushion carriage (3) during the leg stretching process, the seat cushion carriage (3) along the guide rod (4) Sliding backward, the eccentric wheel set (8) is rotated counterclockwise.

Please refer to the sixth, seventh, and eleventh to thirteenth drawings. When the return stroke is performed, the eccentric wheel set (8) rotates clockwise. The use of double cam torque adjustment conversion mechanism eliminates the idle stroke, the structure is simple, and the purpose of the two-way exercise of the same fitness equipment is achieved, which brings great convenience and sports fun, and finally achieves the purpose of two-way muscle training of the same part. The focus of this creation is on the use of eccentric wheels.

In view of the above description of the embodiments, the above-described embodiments are merely a preferred embodiment of the present invention, and the implementation of the present invention is not limited thereto. The scope, that is, the simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the creation of the creation, are within the scope of this creation.
