Description

exercise 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 parts that are connected to the pedals and rotate 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.

Additionally, when parts that rotate with the pedals of an exercise bike are shielded with a case, it becomes difficult to separate the case, increasing the time and cost required for maintenance of internal parts. Therefore, there is a need to improve this.

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 drive 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.
