Description

Upper body exercise bike

The present invention relates to an upper body exercise bike. More specifically, the upper and lower body exercise through the upper body exercise in parallel with the lower body exercise pedaling to simplify the configuration of the exercise conversion unit in the upper body exercise bike to enable the muscles The present invention relates to an upper body exercise bike provided with a braking device on a handle on which an exercise function and a steering function are performed.

Normally, the bicycle was limited to the lower body exercise pedaling, and could not provide the upper body exercise function including the arm and shoulder. In view of this point, the upper body exercise bike that provides the upper body exercise function as well as the lower body exercise inherent to the bicycle is known in Republic of Korea Patent Publication No. 10-1990-9381 and Republic of Korea Patent Registration No. 10-0579530.

The bicycles had a limitation in that the driving force of the rotatable handle is transmitted only to the front wheels, so that it is difficult to effectively distribute the driving force when climbing the slope. The upper body exercise bike of Korean Patent Laid-Open Publication No. 10-1990-9381 handles each of the handles. In the process of reciprocating the handlebars up and down at the intersection, the user's balance may collapse temporarily during driving, particularly while driving on a curved road, and thus there is a safety problem.

In addition, the bicycle of Publication No. 10-1990-16989 adopts a gear driving method instead of a chain driving, but this also neglects the upper body movement and only transmits the driving force in the rear wheel direction from the pedal driving shaft, which makes it difficult to distribute the effective driving force. There is a problem.

In this regard, the present applicant is configured to transmit the driving force of the rotational movement part of the forward and backward reciprocating motion to the rear wheel side through the motion conversion part and the drive transmission part, so that the upper and lower body muscles can be trained in parallel with the lower body motion of pedaling. Invented the upper body exercise bike (Korea Patent No. 10-0840262)

The upper body exercise bike is connected to a pair of spur gears of the upper and lower handles of the upper motion conversion means and coupled to the pair of rotation gears constituting the lower motion conversion means by the link rod, and the rotational movement of the handles through a chain sprocket. The power transmission structure that transmits to the wheel is composed of a motion conversion unit is complicated in structure, the handle of the rotational movement unit is configured to reciprocate back and forth or up and down, it was difficult to perform the steering function smoothly and stably.

In addition, the upper body exercise bike can not be installed on the handle braking lever for braking the bicycle while the handle is rotated for the upper body movement.

In general bicycles, a brake lever that operates the brake by pulling a cable connected to the brakes mounted on the front and rear wheels of the bicycle is installed in the steering wheel, and there is no problem in braking of the bicycle along with steering functions such as change of direction.

However, since the upper body exercise bike cannot be provided with a brake lever for pulling the cable of the brake to the handle that is rotated for steering the upper body and the steering function is provided, the brake lever has to be installed separately from the handle. Therefore, when braking is required during driving, the brake is not performed properly by removing the hand from the handle and operating the brake lever installed separately, and it is not possible to perform the braking smoothly and quickly. It was to cause.

In the present invention, by improving the upper body exercise bike (Korean invention patent No. 10-0840262) to configure a simple structure of the motion conversion unit from it to provide a smoother and more stable steering function, and the rotary drive for the upper body movement and It is intended to provide a braking function with simple and stable operability by constructing a braking device on a handle on which a steering function is performed.

That is, the present invention provides a simple structure to configure the motion change portion and install a brake lever on the handle to perform the rotational drive and steering function for upper body movement of the handle without affecting the rotational drive and steering function of the handle The present invention provides a braking device capable of controlling a brake by operating a brake lever.

The present invention is composed of a rotary movement unit for transmitting power to the pedal drive shaft through the drive transmission unit by rotating the rotary shaft to the rotary drive of the handle of both sides of the rotary shaft, consisting of the upper motion conversion means and the lower motion conversion means interlocked with the rotary motion portion and the movement of the rotary motion portion In the upper body exercise bike composed of a motion conversion unit for transmitting to the drive transmission unit, the rotary motion unit is installed inside the housing to be mounted on the steering rod, to rotate the rotation handles around the axis of rotation, and a pair of bevel gear , Through the lower motion conversion means to transmit the driving force of the rotary handle to the drive transmission,

The handle connected to the rotary shaft of the rotary motion unit is provided with a brake lever to enable the brake mounted on the front and rear wheels of the bicycle.

The present invention can be provided in the upper body exercise bike, the upper body exercise bike (Korean Patent No. 10-0840262) by the simple structure of the motion conversion unit of the structure to provide a compact upper body exercise bike,

In addition, a brake lever is installed on the steering wheel that performs rotational drive and steering function for upper body movement, enabling the brake to be controlled from the handle that performs upper body movement and steering operation, providing a fast and stable braking function to the upper body bicycle. With its smooth and convenient usability and operability, there is an advantage such as to further improve the safety of the upper body exercise bike.
