Description

[Detailed description of the invention] The present invention is a grip cover for a brake lever for a drop bundle, more specifically, a bracket for a brake lever that is attached to a drop bundle of a bicycle. The present invention relates to a grip cover that is attached to a bracket having a rectangular cross section and having a handle portion that allows a driver to operate the bundle by applying his or her weight to the grip portion.

Generally, in a bicycle in which a brake lever is attached to the bent rod part of the drop bundle, when riding in a forward leaning position, the brake lever bracket, which is formed to be larger than the thickness of the bundle, is grasped and the bundle is bundled. It is ready for operation.

Conventionally, a grip cover made of a soft material is attached to the outside of the bracket of the brake lever to soften the contact between the bracket and the hand. When the grip part of this cover is grasped, the shape of the grip part is difficult to fit into the hand, and a large space is created between it and the concave part of the palm, resulting in the above-mentioned Since it is difficult to develop a large grip force unless you squeeze hard until there is no space left, this has the disadvantage that your hands tend to get tired easily, and furthermore, your hands tend to get tired even when driving long distances.

This invention was devised in view of the above-mentioned shortcomings, and its purpose is to be able to generate a large amount of grip force just by lightly squeezing the grip part, and to prevent hand fatigue even when driving long distances. The object of the present invention is to provide a brake lever grip cover for a drop bundle that can reduce the amount of damage caused by the brake lever.

Therefore, the present invention is a brake lever bracket that is attached to a drop bundle of a bicycle, and includes a grip part that the bicycle rider holds in a forward-leaning position, and the bicycle driver's weight is applied to the grip part to bundle the brake lever. In a grip cover that is attached to a bracket having a rectangular cross section to enable operation, a cover body that covers the outer peripheral surface of the bracket has a rectangular cross section and is attached to the drop bundle of the cover body. On the outside of the case, a bulge is provided at a part where the recess of the palm that grips the bracket is located, and which bulges outward relative to other parts of the layer and is adaptable to the recess. It is characterized by the fact that it has been provided.

An embodiment of the grip cover of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a cover body that covers the outer peripheral surface of a brake lever 4 that is attached to a drop bundle 3 of a bicycle and has a rectangular cross section. A main body 1 is formed into a rectangular cross section by opposing side walls 11 and 12, a front wall 13 and a rear wall 14, and an upper wall 15, each having a square bulge.
A recessed portion 1 that fits the outer periphery of the bracket is provided therein.
6 is provided, and a grip portion 17 is formed on the outer periphery.

A notch hole 18 is provided in the earthen wall 15 from the upper part of the rear wall 14, and the lever main body 41 of the brake lever 4 is made to protrude from the notch hole 18.
A cylindrical support part 19 is provided at the corner connecting the two, and the guide tube 6 that guides the operating wire 5 is supported by this support part 19.

On the other hand, as shown in FIG. 8, a plurality of minute protrusions 11a, 13a, 14a are provided on the outside of one of the side walls 11, the front wall 13, and the rear wall 14 among the both side walls 11.12,
With these protrusions 11a, 13a, 14a,
Four parts 7a of the palm 7 that prevent the hand from slipping when gripping the grip part 17 and grip the 7111 part 17 on the outside of the other side wall 12 located on the outside when attached to the drop bundle 3; A bulging portion 2 is provided at a portion where the palm is located, the bulging portion 2 bulging outward relative to other portions around the portion and being adaptable to the recess 7a of the palm 7,
When the grip portion 17 is lightly gripped, the concave portion 7a of the palm fits into the convex portion 2, so that there is almost no space between the convex portion 2 and the concave portion 7a of the palm.

Therefore, the bulging portion 2 increases the degree of bulge from the rear wall 14 side to the front wall 13 side, and also increases the bulge degree from the upper wall 15 side to the lower end opening 20 side, so that the entire bulge portion 2 increases. The grip portion 17 is shaped like a heap so that it can fit into the concave portion 7a of the palm when the grip portion 17 is lightly gripped.

Further, the bulging portion 2 has a higher hardness than the cover main body 1,
When the grip part 17 is gripped and the concave part 7a of the palm fits into the bulge part 2, the concave part 7a of the palm is stimulated to eliminate hand fatigue.

In order to make the hardness of the bulging part 2 higher than that of the cover body 1, the bulge part 2 is formed of a different material that is harder than the cover body 1, and the cover body 1 is made by primary vulcanization. After molding, the bulge 2 is attached to the outer surface of the side wall 12 of the cover main body 1, and then the cover main body 1 and the bulge 2 are attached.
The hardness of only the bulging part 2 can be reduced by secondary vulcanization by integrally bonding the bulging part 2 with the cover main body 1 using a soft material, or by molding the bulging part 2 integrally with the cover body 1 from a soft material. It makes the price higher.

The bulging portion 2 may be fixed using an adhesive or a screw, and a fitting protrusion and a fitting portion that engages with the protrusion may be provided between the bulging portion 2 and the cover main body 1. may be provided and fixed.

As described above, the present invention is a brake lever bracket that is attached to a drop bundle of a bicycle, and includes a grip part that the bicycle rider grips while leaning forward, and the rider's weight is applied to the grip part. In a grip cover that is attached to a bracket having a rectangular cross section and which enables bundle operation, the cover body that covers the outer peripheral surface of the bracket is approximately square in cross section, and the drop bundle of the cover body is substantially rectangular in cross section. A bulging part that bulges outward relative to other parts around the part and is adaptable to the recess at the part where the recess of the palm that grips the bracket is located on the outside when attached to the bracket. Therefore, when a bicycle rider grasps the grip cover attached to the bracket of the brake lever and operates the bundle in a forward leaning posture, there is no space between the grip cover and the recessed part of the palm.
Since the concave part of the palm can be brought into close contact with the bulge, the grip cover fits well in the palm, making it very easy to operate the bundle in a forward-leaning position. The concave part of the palm fits into the bulge in a natural grip state, and the concave part of the palm can be used to transmit force from the bulge of the grip cover to the bracket.
This greatly reduces hand fatigue even when driving long distances.

In other words, when pressing the pedal while leaning forward and applying the weight of the driver to the grip of the bracket, if the pressing load is high, a large pressing force is required, but the force that pulls the bundle toward the driver (so-called Although the reaction force of this bundle pulling force can be transmitted to the bracket via the concave part of the palm of the metacarpal bone located on the + side of the hand, it does not place stress on the fingertips. This allows you to operate the bundle without any hassle, which greatly reduces hand fatigue.
