Description

Braking System for Upper Body Exercises {Bicycle for the exercise of the upper part of body}

The present invention relates to a braking device for an upper body exercise bike, and more particularly, to an upper body exercise bike capable of upper body exercise (Registration Utility Model No. 20-0449042 of the present applicant), which has a simple structure and a stable operating braking device. A braking device for an exercise bike.

Normally, the bicycle is limited to the lower body movement by pedaling, and relatively does not provide the upper body movement function including the arm and shoulder. With this in mind, there are known upper body exercise bikes that provide the upper body exercise function as well as the lower body exercise inherent to the bicycle (Korean Patent Publication No. 10-1990-9381 and Korean Patent Registration No. 10-0579530).

However, the above-mentioned bicycles have a limitation in that the driving force of the rotatable steering wheel is transmitted only to the front wheels, so that it is difficult to distribute the effective driving force when climbing the slope. In the process of reciprocating each handle up and down the intersection, there is a risk that the user's balance may collapse temporarily during driving, particularly while driving on a curved road, which has a safety problem.

In addition, the bicycle of the Patent Publication No. 10-1990-16989 adopts a gear driving method instead of a chain driving, but this also has a negligible upper body movement and only transmits the driving force in the rear wheel direction from the pedal drive shaft, which makes it difficult to effectively distribute the 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, and the upper and lower body muscles can be trained in parallel with the lower body motion of the pedal. Invented the upper body exercise bike (Korea Patent No. 10-0840262)

The upper body exercise bike is connected to the upper and lower handles of the upper motion conversion means is a pair of spur gears and coupled to a pair of rotation gears constituting the lower motion conversion means by a link rod to the rotational movement of the handle 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.

Accordingly, the upper body exercise bike was improved, and the exercise conversion unit was formed in a compact structure, and the upper body exercise bike was able to provide a steering function more smoothly and stably. (Korean Registered Utility Model No. 20-0449042)

The present invention is to achieve a braking function with a more convenient usability and stable operability by configuring a braking device on the handle that the rotational drive and steering function for the upper body movement in the applicant's upper body exercise bike.

In the above-described conventional upper body exercise bike, the handle is rotated for the upper body exercise so that a braking lever for braking the bicycle while driving cannot be installed on the handle.

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, the applicant's upper body exercise bike is to perform a steering function at the same time as the steering wheel is rotated for the upper body movement, can be installed a brake lever for pulling the cable of the brake on the handle that is rotated for the upper body movement and the steering function is performed. The brake lever had 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 steering wheel and operating the brake lever installed separately, and it causes serious problems such as safety accidents while driving smoothly and quickly without braking. It could have been.

Accordingly, in the present invention, the brake lever is installed on the handle that performs the rotation drive and steering function for the upper body motion, and the brake lever of the handle does not interfere with the rotation drive and the steering function of the handle in the handle having the upper body motion and the steering function. By controlling the brake to enable the control of the upper body exercise bike to provide a fast and stable braking device.
