Description

bicycle auxiliary handle

technical field

The utility model relates to an auxiliary handle for a bicycle, in particular to an auxiliary handle which is assembled at both ends of the bicycle handle and extends obliquely forward.

Background technique

Bicycle is a lightweight and convenient means of transportation. With the improvement of living standards, automobiles and motorcycles have become more and more popular. The rider can change his posture during long-distance riding, so as not to be too stiff. Therefore, the operator will assemble a handlebar (40) (as shown in FIG. Auxiliary handle (41), the axis of auxiliary handle (41) and bicycle handle (40) is perpendicular, and the rider can hold the bicycle handle (40) to ride, or lean on the auxiliary handle (41) to ride, although The rider can change the posture, but the arm still feels tired and sore after a long distance. The reason is that the known auxiliary handle (41) does not conform to ergonomics.

When the hands of the human body are in the natural hanging state, the tiger's mouth and the human body are in an oblique state. This is the most natural and comfortable posture. Assuming that the hand is stretched forward, the tiger's mouth and the palm are still oblique, and the elbow Outward, so is the most natural posture, but the existing auxiliary handle (41) is vertically arranged at the two ends of the bicycle handle (40), so it is necessary to open the tiger's mouth to hold it with the palm, and the holding posture is to turn the palm slightly Make the tiger's mouth face upwards. At this time, the radius and ulna of the forearm are also slightly turned at an angle to straighten the elbow (A). Riding in such an ergonomic condition, it is no wonder that the arm is prone to soreness. In addition, the existing auxiliary handle (41) does not have any design for supporting the palm, so it is necessary to ride with both palms firmly grasped, which makes it very easy to get tired.

Utility model content

The main purpose of the utility model is to provide a bicycle auxiliary handle which has an appropriate inclination and can be leaned against by the palm and conforms to ergonomics.

In order to achieve the above object, the bicycle auxiliary handle provided by the utility model is an auxiliary handle assembled on the two free ends of the bicycle handle. The free ends of the grip part of the handle are inclined towards each other and form an angle with the axis of the bicycle handle, wherein:

On the top surface of the joint part of the auxiliary handle, there is a plane part that can be flattened by the palm. The plane part is also provided with a supporting flange extending toward the free end of the bicycle handle. The free end of the supporting flange is slightly upward.

In the bicycle auxiliary handle, the middle section of the free end of the grip part of the auxiliary handle forms a concave part for fingers to be naturally placed from above, while the left and right sides protrude correspondingly.

In the bicycle auxiliary handle, the free end of the grip part of the auxiliary handle is provided with an end plug, and the concave part is formed on the end surface of the end plug.

In the bicycle auxiliary handle described above, the outer edge of the top support flange and the grip part are connected by an arc edge.

The bicycle auxiliary handle mentioned above, wherein, the top support flange and the plane part of the joint part are integrally arranged.

In the bicycle auxiliary handle mentioned above, the space between the top support flange and the joint part is detachable.

Detailed ways

Please refer to Fig. 1 and Fig. 2, the bicycle auxiliary handle provided by the utility model, the auxiliary handle (10) has a rod-shaped grip part (11), and one end of the grip part (11) forms a joint (12), there is a through hole (13) on the joint portion (12), the peripheral edge of the hole (13) is also provided with a sectional groove (14) that runs through the peripheral wall, so that the hole (13) forms a C shape, and a Pass through the coaxial perforation (141) and the screw hole (142) of the peripheral wall on both sides of the cut groove (14), after the auxiliary handle (10) is placed on the two ends of the bicycle handle (20) by the perforation (13), then with The bolt passes through the perforation (141) and is screwed in the screw hole (142), and it can be clearly seen from the top view of Fig. 2 that the auxiliary handle (10) has an angle of inclination, so that the grips of the two auxiliary handles (10) (11) The free ends are inclined toward each other, so that the angle β between the gripping portion (11) and the bicycle handle (20) is about 80 degrees.

The purpose of the oblique design of the auxiliary handle (10) in the above-mentioned utility model is to make the rider lift his hand in a natural posture with the elbow (A) outward when placing his hand on the auxiliary handle (10), so that The palm of the hand is flatly attached to the grip portion (11) at an inclined angle to conform to the ergonomic design, so that the rider can ride in a more natural and relaxed posture and reduce fatigue.

In addition, an end plug (15) is provided at the free end of the grip portion (11). The middle section of the end plug (15) has a recessed portion (151), and the left and right sides protrude correspondingly for the fingers of the rider. Naturally placed on the concave part (151), as shown in Figure 3, when the palm is placed on the grip part (11), place the thumb on the concave part of the grip part (11), or as shown in Figure 4 The forefinger is buckled in the concave portion (151) (the most natural posture is to buckle in the concave portion with the index finger straight).

As can be seen from Fig. 1, Fig. 2 and Fig. 4, the top surface of the joint portion (12) of the auxiliary handle (10) forms a plane portion (120) connected with the grip portion (11). (120) is provided with a top support flange (16) extending towards the free end of the bicycle handle (20) and the end slightly upwards, the side edge of the top support flange (16) and the grip part (11) form a Arc-shaped connection, the design of the planar part (120) and the top support flange (16) is for the rider's palm to be easily placed on the planar part (120), while the outside of the palm obtains the top support flange (16). ) so as not to make the palm slip off, such a safety design allows the rider not to hold the grip (11) tightly with his hand, and then ride in a safe and relaxed posture to reduce fatigue.

Among the drawings of the above-mentioned utility model, the supporting flange (16) is integrally extended from the plane part (120), and it can also be made detachable, that is, an additional supporting flange (16) with an upturned end is manufactured. This propping flange (16) is assembled on the existing auxiliary handle end face again.

As can be seen from the above, the design of the present utility model has four characteristics, 1. the grip portion (11) that is inclined. 2. The concave part (151) provided at the end of the grip part (11). 3. The flat part (120) provided on the top surface of the joint part (12) of the auxiliary handle (10). 4. The top support flange (16) whose end is slightly upturned. These four design features can provide different effects:

1. Since the grip parts (11) of the two auxiliary handles (10) are set in such a way that the free ends are inclined towards each other, the rider can be placed in a natural posture with the elbows facing outwards and the mouth of the tiger is inclined, so it is ergonomically designed Will reduce arm fatigue.

2. Since the end of the grip part (11) is provided with a recessed part (151), it can be placed naturally for the thumb or forefinger, and allows the rider to change the posture of the arm.

3. The flat part (120) provided at the joint part (12) can be placed by the rider's palm to control the direction of the handlebar in a light way.

4. The top support flange (16) at the end of the joint (12) can prevent the palm from slipping off, so that the rider does not need to deliberately grasp the grip (11) and can be placed flat in an easy and safe manner.

To sum up, the design of the utility model can allow the rider to ride in the most natural and comfortable posture to reduce fatigue, especially for long-distance riders, they can feel the design advantages of the utility model.
