Abstract

A bicycle handle includes a holding rod middle piece, pivotally connected to a front frame of a bicycle. A first holding portion and a second holding portion corresponding to the first holding portion exist at left and right sides of the holding rod middle piece. The first holding portion and the second holding portion bend and extend towards a forward direction of the bicycle to form forward bending arc portions. The forward bending arc portions extend towards a backward direction of the bicycle to form backward bending arc portions. The backward bending arc portions extend towards the backward direction of the bicycle to form a rear rod section. A relative distance between the two backward bending arc portions is greater than a relative distance between the two forward bending arc portions, so as to expand a turning radius of the bicycle handle, thereby meeting human engineering and being beneficial to smoothness of rotary operations.

Description

Bicycle handle

The present invention relates to a handle, and more particularly to an ergonomic bicycle handle that is easy to rotate.

According to the conventional bicycle handle, as shown in FIGS. 1A and 1B, a hollow tube body made of a metal material or a carbon fiber material mainly comprises a grip 1 which is disposed laterally in front of the rider and in the middle thereof. A pivot hole (not shown) is provided, a screw 2 is inserted into the front frame 3 of the bicycle to be pivoted to the front frame 3 of the bicycle, and the bicycle handle is pivotally connected to the front frame 3, and the rod is gripped. Each of the left and right sides of the 1 extends toward the forward direction of the bicycle and bends a bow-shaped grip portion 4.

In this way, the rider's hands can be held on the left and right sides of the grip 1 or on the grip portion 4, thereby allowing the body riding posture to be changed, thereby avoiding fatigue in the same posture for a long time. Especially when riding a bicycle on a smooth road, it is easier to climb the slope, and the riding speed will be faster than climbing. At this time, the rider's hands will be held on the left and right sides of the grip, although the rider is quite fit. Straight, causing a large wind resistance, but it is not laborious because the road is flat. On the other hand, if the situation is climbing, in order to reduce the wind resistance, the bicycle is pushed forward, the rider's hands will be changed to the position of the grip portion 4, and the body will reduce the wind resistance in a posture of lowering the height, thereby facilitating the bicycle to advance. .

However, the distance between the two grip portions 4 of the conventional bicycle handle is the same as the width of the grip bar 1. When the rider grips the left and right sides of the grip bar 1 during the turn, the center of the hand and the grip bar The distance is small and the relative radius of gyration is small. However, because the body is straight, the proportion of the hands to bear the weight of the body is less, and the operation has no effect. If the climber is in the climbing condition, the rider's hands will be held in the grip portion 4. Since the grip portion 4 is lower than the grip 1, the rider's body is bent and tilted, and both hands bear most of the weight of the front end of the body. And because the radius of rotation r is small, it is not only not conducive to the bending operation, but also more It is easy for the front wheel to deflect too much and get out of control because of the excessive bending operation. It is also known that the grip portion 4 is a straight line, which does not conform to the ergonomic angle of the human hand with the four fingers and the thumb grip, and affects the smoothness of the rider's hand operation.

The main object of the present invention is to solve the problem that the conventional bicycle handle has a small radius of rotation when it is bent, and fails to conform to ergonomics, resulting in insufficient smooth operation.

In order to achieve the above object, the present invention discloses a bicycle handle, which comprises a middle portion of a grip for pivoting with a front frame of the bicycle, and a left and right sides of the middle portion of the grip respectively have a first grip portion and a second grip corresponding to the first grip. The first and second grip portions are bent toward the forward direction of the bicycle and extend to form a forward curved portion, and the forward curved portion further extends a backward curved portion toward the bicycle receding direction, and the backward curved portion The portion further extends a rear rod segment toward the bicycle receding direction, and the distance between the rear curved portions is greater than the distance between the forward curved portions to facilitate the operation of the bicycle turning.

Further, the distance between the rear curved portions is greater than the distance between the rear rear rod segments.

Further, the rearward curved portion is an arcuate outer shape that protrudes outward in a direction parallel to the bicycle handle.

Further, the center of the backward curved portion is collinear with the center line of the rear rod segment and is outwardly offset from the center line of the forward curved portion.

Further, the surface of the backward curved portion is provided with at least one anti-slip plane for hand-held contact.

Further, the first grip portion and the second grip portion are not in line with the middle portion of the grip.

Thereby, the distance between the rearward curved portions is greater than the relative two of the forward curved portions. The distance between the rotation of the present invention is greater than that of the conventional bicycle handle when the hand is bent in the backward curved portion, so that the hand-operated bicycle can be bent less than the conventional bicycle handle. To solve the problem that the conventional operation is not smooth enough, and the rearward curved portion is provided with a non-slip plane for grasping the hand to prevent the hand from sweating.

And the rearward curved portion is just for the palm to be held by the four fingers, the thumb is placed against the forward curved portion, and the backward curved portion is expanded outwardly from the forward curved portion to make the forward curved portion The angle position for the thumb to hold the hand is just ergonomic and provides a comfortable grip.
