Description

bicycle auxiliary handle

The present invention is a bicycle auxiliary handle with an ergonomic design of expanding outwards first and then shrinking inwards, with a diversion design of high inside and low outside, and a unique wind-breaking design.

With the rise of most people's awareness of environmental protection, energy saving and carbon reduction, bicycles have been widely used in sports, commuting, professional racing and other purposes. For high riding efficiency, it is often set on both sides of the bicycle handlebar near the center to generally include a pair of auxiliary handles and a pair of cushions, so that the rider's arms can rest on the auxiliary handles or cushions during long-distance riding. Lean on the pad to support the weight of the body part for proper rest and relaxation, so that the rider can maintain better physical fitness during long-distance racing or sports.

Commonly used bicycle auxiliary handles, such as the patent No. 542168 of the Republic of China Announcement No. 542168 "Bicycle Handle Positioning Improvement Structure by Cushion", can be seen from its various drawings, and each auxiliary handle is a round tube, which usually has a straight section and an upward curved section, providing the forearm of the rider's arm against the straight section of the auxiliary handle, while his hand can grasp the upward curved section of the auxiliary handle; The circular tube design is not designed for the structure and external shape of the human arm. As a result, when the rider puts the forearm against the straight section of the auxiliary handle which is a round tube for a long time, the upper surface of the straight section The convex arc surface will be in contact with the forearm of the arm, so that the forearm of the rider's arm is not easy to rest on it, causing fatigue or discomfort easily. And can't satisfy the demand that the rider rests against.

And when the rider participates in a long-distance professional race with a bicycle assembled with this kind of auxiliary handle of the conventional type, the upper surface of the straight section of the auxiliary handle will form a convex arc surface and contact with the forearm of the arm, making the convex arc surface There is a gap between the forearm and the arm, which causes the air flow to be unstable and forms resistance, which relatively reduces the efficiency of the rider's pedaling work, making it a major flaw that needs to be improved in professional racing where every second counts.

In addition, the shoulder width of the general rider is wider than the width of the conventional bicycle auxiliary handle set on both sides of the handlebar near the center, and the arms of the shoulders on both sides of the upper body of the rider extend from the arms to the front end The hands that provide the upward bending section for holding the auxiliary handle are generally in the shape of a triangle, and the auxiliary handle is traditionally located on both sides of the bicycle handle near the center, and is parallel to the front, so that when the rider is on a long distance When riding, the arm can lean against the auxiliary handle or the cushion to support the weight of the body part. It is expected to be used as a proper rest and relaxation. The original triangular shape of the part will be set parallel to the two auxiliary handles because the arms have to be succumbed to the two auxiliary handles, so that the rider's two arms must be retracted toward the bicycle handlebars near the center and placed in a parallel state. Relying on the pair of auxiliary handles causes the rider to easily feel tired or uncomfortable when the forearm rests against the pair of auxiliary handles for a long time, which cannot meet the rider's need for rest.

No. I 719729 "Rest Handle and Bicycle Handle Assembly with the Rest Handle" patent case of the Republic of China Certificate, is that the upper surface of the abutment section of the rest handle is depressed to form an abutment arc surface to provide the rider The outer surface is arc-shaped and the forearm rests on it to improve the conventional bicycle auxiliary handle. Tired easily when holding hands or The absence of discomfort.

And the above-mentioned No. I 719729 patent case of the certificate number of the Republic of China, as shown in its diagram, its rest handle is like a general bicycle auxiliary handle, which is still maintained at the bicycle handle near the central two sides, and is parallel to the front. It is not aimed at the shoulder width of the average rider, but is wider than the rest handles located on both sides of the bicycle handlebars near the center, and the shoulder arms on both sides of the upper body of the rider, and the arms extending from the arms to the front end provide grip assist handles Between the hands of the most forward-bending section is generally in the shape of a triangle, so when the rider is riding for a long distance, he is still like a general bicycle auxiliary handle, and his arms must also be placed parallel to the two rest handles. As a result, the rider's two arms must be retracted towards the bicycle handlebars near the central two sides in order to cooperate, and they are in a parallel state to lean against the rest handle, causing the rider's forearm to rest on the above-mentioned forearm for a long time. When resting on the handlebars, it is easy to feel tired or uncomfortable, which cannot meet the needs of the rider to lean against and rest.

Therefore, how to design a bicycle auxiliary handle that can meet ergonomics, effectively improve the flow guide and have a wind-breaking design is what the bicycle auxiliary handle manufacturers are eager to seek and improve.

The present invention is a bicycle auxiliary handle which conforms to ergonomics and is designed to first expand outwards and then shrink inwards, has a diversion design with high inside and low outside, and has a unique wind-breaking design.

In order to achieve the aforementioned purpose, the present invention provides a bicycle auxiliary handle, which is designed in pairs and combined on the two sides of the bicycle handle near the center; each auxiliary handle includes: a combining section, a supporting section, and a holding section ; Wherein, the joint section is combined with the bicycle handle, the upper surface of the supporting section is a concave arc surface and is located at the front end of the joint section, and the supporting section starts from its rear end to its front end The direction has an outwardly expanding section, an inwardly retracting upwardly inclined section, and a downwardly inclined section in sequence, and the holding section is located at the front end of the downwardly inclined section of the supporting section.

In addition, a pair of rest seats can be respectively combined with the joint sections of the pair of auxiliary handles, and the elbows of the rider can rest on them.
