Description

bicycle assist handle

The new model is a bicycle auxiliary handle with an ergonomically expanding outward and then inwardly retracting design, a high-inside and outside-low diversion design, and a unique wind-breaking design.

With the rise of most people's awareness of environmental protection and energy saving and carbon reduction, bicycles have been widely used in sports, commuting, professional racing and other purposes. For high riding efficiency, the bicycle handlebars are often re-arranged near the center on both sides, and generally include a pair of auxiliary handlebars and a pair of abutting pads, so that the rider's arms can abut against the auxiliary handlebars or abutting pads during long-distance riding. The cushion supports 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.

Conventional bicycle auxiliary handlebars, such as the Patent No. 542168 of the Republic of China "Bicycle Handlebar Pad Positioning Improvement Structure", can be seen from its various drawings that each auxiliary handlebar is a round tube, which usually has a straight and an upwardly curved section, which provides a straight section where the forearm of the rider's arm can abut against the auxiliary handle, and his hand can grasp the upwardly curved section of the auxiliary handle; The round tube design is not designed for the structure and external shape of the human arm, so that when the rider presses the front arm of the arm against the straight section of the auxiliary handle which is a round tube for a long time, the upper surface of the straight section will The convex arc surface is in contact with the forearm of the arm, so that the forearm of the rider's arm is not easy to rest on it, which makes it easy to feel tired or uncomfortable. However, it cannot meet the needs of the rider to rest.

And when the rider participates in a long-distance professional race with a bicycle assembled with this kind of auxiliary handle, the upper surface of the straight section of the auxiliary handle will form a convex surface in contact with the forearm of the arm, so that the convex surface will be in contact with the forearm of the arm. There is a gap with the front arm of 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 defect in professional racing where every minute counts and needs to be improved.

In addition, the width of the shoulders of the general rider is wider than that of the conventional bicycle handlebars located on both sides of the bicycle handlebar near the center, and the arms of the shoulders on both sides of the rider's upper body, and the arms extend from the arms to the front end. The hands that provide the upward bending section for holding the auxiliary handle are roughly in the shape of a triangle, and the conventional auxiliary handle is located on both sides of the center of the bicycle handle, and is parallel to the front. When riding, its arms can rest against the auxiliary handle or on the cushion to support the weight of the body part. It is expected that when it is properly rested and relaxed, its arms and the arms extending from the arms to the foremost end provide the hand that holds the auxiliary handle and bends upwards The original triangular shape between the parts will be set parallel to the two auxiliary handlebars because the arms must be bent, so that the two arms of the rider must be retracted toward the bicycle handlebars near the center on both sides and in a parallel state. Relying on the pair of auxiliary handles causes the rider to easily feel tired or uncomfortable when he presses his forearm against the pair of auxiliary handles for a long time, and cannot meet the needs of the rider for rest.

For example, in the patent case of the Republic of China Certificate No. I 719729 "rest handle and bicycle handlebar assembly with the rest handle", the upper surface of the resting handle of the rest handle is recessed to form an abutting arc surface to provide riders with The outer surface is curved and the forearm is abutted to improve the habitual bicycle auxiliary handle. The circular tube design is not designed for the structure and external shape of the human arm, which causes the rider to press the forearm of the upper arm against the auxiliary for a long time. Tired easily or The absence of discomfort.

In the above-mentioned patent case of the Republic of China No. I 719729, as shown in the drawing, the rest handle, like a general bicycle auxiliary handle, is still located on both sides of the bicycle handle close to the center, and is arranged in parallel to the front. It is not aimed at the shoulder width of the general rider, but is wider than the rest handlebars located on both sides of the bicycle handlebar near the center, and the arms on the shoulders on both sides of the rider's upper body, and the arms extending from the arms to the front end provide grip assist handles Between the hands of the upwardly curved section at the front end is roughly a triangle shape, so when the rider is riding for a long time, it is still like a general bicycle auxiliary handle, and his arms must also bend to the two resting handles and set them in parallel. As a result, in order to cooperate, the two arms of the rider must be retracted toward the two sides of the bicycle handle near the center, and be in a parallel state to abut against the rest handle, causing the rider to press the forearm of the arm against the above-mentioned handle for a long time. When resting on the handlebars, it is easy to feel tired or uncomfortable, and it cannot meet the needs of the rider to rest.

Therefore, how to design a bicycle auxiliary handle which can be ergonomically, can effectively improve the diversion and have a wind-breaking design is what the bicycle auxiliary handle manufacturers are eager to seek and improve.

This new model is a bicycle auxiliary handle with an ergonomic design that first expands outward and then shrinks inward, a diversion design with a high inner and an outer low, and 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 both sides of the bicycle handle near the center; each auxiliary handle includes: a combining section, a supporting section, and a gripping section ; Wherein, the joint section is combined with the bicycle handle, the upper surface of the bearing section is a concave arc surface and is located at the front end of the joint section, and the bearing section starts from its rear end to its front end The direction sequentially has an outwardly expanding section, an inwardly retracting upwardly inclined section, and a downwardly inclined section, and the holding section is located at the front end of the downwardly inclined section of the bearing section.

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