Description

Exercise bike{FITNESS BIKE}

The present invention relates to an exercise bike in which a side case is installed detachably to facilitate maintenance work.

In general, indoor exercise equipment to strengthen muscle strength, weight equipment to strengthen muscle strength, and aerobic exercise equipment to strengthen cardiopulmonary function are widely used as fitness equipment.

Aerobic exercise equipment includes a treadmill that allows users to walk or run on a crawler track, an exercise bike that rotates the pedals to strengthen leg muscles while doing cardiopulmonary exercise, and a stepper that provides the effect of climbing stairs. It is broadly divided into:

The exercise bike is installed in a designated area, and the wheel rotates when you pedal, allowing you to exercise. These exercise bikes can be divided into spinning bikes that allow you to perform spinning exercises, and indoor bikes that rotate the wheels by rotating the pedals in the forward direction like a bicycle.

In an exercise bike, the rotating parts connected to the pedals are exposed to the outside of the exercise bike. Therefore, when turning the pedal, a safety accident may occur in which foreign substances get caught in the parts that rotate with the pedal or a child's hand gets caught.

The second mounting hole portion 122 forms a hole in the second cover body 121 facing the disk portion 50 so that the disk portion 50 is located. The second mounting hole portion 122 has an inner diameter that is larger than or equal to the outer diameter of the second outer disk 54 so that the second outer disk 54 is positioned.

The second extension panel 123 extends upward from the second cover body 121 and shields the other side of the first frame 23 in the width direction (W). The second extension panel 123 has a plate shape like the second cover body 121 and is formed integrally with the second cover body 121.

The lower frame 25 is bolted to the lower part of the second frame 24, and the upper frame 26 is bolted to the upper part of the first frame 23. In addition, the upper cover part 31 is bolted to the upper part of the upper frame 26, and the lower cover part 34 is bolted to the lower part of the lower frame 25.

The wheel cover part 37 is bolted to the upper cover part 31 and the lower cover part 34, and the front case 38 and the protective case 39 are bolted to the first frame 23.

And the first side cover part 110 and the second side cover part 120 are attached to one side and the other side of the support frame part 20 and the exterior case 30 in the width direction (W), respectively.

The wheel portion 130 is located inside the side frame 100, and various modifications are possible within the technical concept of being rotatably installed on the second frame 24 of the support frame portion 20. The wheel unit 130 rotates together with the disk unit 50.

The wheel unit 130 is rotated by the rotation of the pedal 70, and an electromagnet is installed inside the wheel unit 130. By adjusting the strength of the electromagnet provided in the wheel unit 130, the amount of force required to rotate the wheel unit 130 can be adjusted, and thereby the exercise intensity of the exercise bike 1 can be adjusted.

The wheel unit 130 provided on the exercise bike 1 can be operated in freewheel mode and non-freewheel mode. The operation of the wheel unit 130 is switched between freewheel mode and non-freewheel mode by the operation of the drive unit using a motor.

Since the wheel portion 130 of the exercise bike 1 uses a one-way clutch bearing, power is transmitted only when rotating in the forward direction. In addition, since the driving unit provided in the wheel unit 130 operates and the gear that transmits power moves, power is transmitted even when the pedal 70 rotates in the reverse direction, and the wheel unit 130 operates in a non-freewheel mode in which the wheel unit 130 rotates in the reverse direction. It can be.

The outer shape of the wheel portion 130 is disk-shaped, and is rotatably supported on the second frame 24.

A handle 140 that the user can hold is installed on the first frame 23. A display unit 150 is installed on the first frame 23 adjacent to the handle 140 to easily check the operating status and exercise records of the exercise bike 1.

The display unit 150 may output exercise information such as the speed of the exercise bike 1, rotational load, etc. on the screen.

A seat post 162 is installed on the upper side of the post 21 to support the lower side of the seat 160. The seat post 162 may be installed inside the post 21 to have an adjustable height. Of course, the seat post 162 can be fixed to the inside of the post 21. The cross section of the seat post 162 may be formed in various ways depending on the shape of the post 21.

Since the seat post 162 is installed to be height-adjustable inside the post 21, the height of the seat 160 can be appropriately adjusted according to the user's height, physical condition, and exercise tendency.

In the exercise bike 1 as described above, no empty space is formed between the side frame 100 and the disc unit 50, so the phenomenon of a child's hand being caught around the rotating disc unit 50 and foreign substances are prevented. It can reduce the risk of safety accidents by preventing jamming.

On the other hand, when repair or replacement work is required for parts installed on the inside of the exercise bike 1, the time and cost required for maintenance work on the parts located inside the side frame 100 due to the detachable structure of the side frame 100 can be reduced.

As described above, the present invention has been described with reference to the illustrative drawings, but the present invention is not limited to the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformation can occur. In addition, although the operational effects according to the configuration of the present invention were not explicitly described and explained while explaining the embodiments of the present invention above, it is natural that the predictable effects due to the configuration should also be recognized.
