Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to bicycle brake levers.
In particular, the present invention relates to a brake lever attached to a drop handle that improves the reliability and safety of its operation.

[Prior art and its problems]

Among bicycle brake levers, the brake lever attached to the drop handlebar is designed to extend downward from the upper part of the brake bracket, which is attached to the front of the U-shaped curved portion at both ends of the drop handlebar in a forward-protruding manner. It is mounted so that it can rotate. Furthermore, in general, conventional brake levers have a smooth finish on the surface where the fingers rest, in order to avoid hurting the hands and fingers due to the reaction force of gripping when braking suddenly. . For the above reasons, there has been a problem in that when attempting to perform a braking operation while the vehicle is running with a hand placed on the brake bracket, the hand tends to slip off the surface of the brake lever. In order to solve this problem of slippage, it is possible to form irregularities on the surface of the brake lever itself, but as mentioned earlier, these irregularities dig into the skin during sudden braking operations, making it difficult to use the brake lever. This is not a very good solution as it may make you feel uncomfortable and cause pain in your hands and fingers. This idea was devised based on the above-mentioned circumstances, and effectively prevents fingers from slipping while maintaining the smoothness of the surface and not causing a worsening of the usability during sudden braking. The object of the present invention is to provide a brake lever that can perform reliable and safe braking operations by preventing the above-mentioned problems.

[Means to solve the problem]

In order to solve the above problem, this invention takes the following technical measures. The brake lever is rotatably supported at the upper part of the brake bracket attached to the handlebar, and a retaining hole is formed on the surface of the tip of the brake lever, and a rubber or soft synthetic resin material is inserted into the retaining hole. It is characterized in that the anti-slip member is buried so that its surface portion is flush with the surface of the brake lever or is slightly raised.

[Effect]

The anti-slip member made of rubber or soft synthetic resin itself has high frictional resistance against the skin. Furthermore, even when wet, the frictional resistance against the skin is greater than that of smooth metal. Moreover, it can be easily compressed and deformed by receiving a pressing force. In the present invention, such a non-slip member is buried so that its surface portion is flush with the surface of the brake lever or is slightly raised. As a result, the anti-slip member is exposed at the tip of the brake lever, either flat or with a slight protuberance, thereby forming an anti-slip part that has high frictional resistance against the skin and can compress and deform under pressure. be done. According to the present invention, even if the finger slides from the proximal surface of the lever toward the tip, the above-mentioned non-slip portion effectively prevents the finger from sliding further, and the finger attempting to operate the brake is prevented from sliding. Not only does it have the effect of preventing the driver from leaving the lever, but it can also be expected to have the following unique effects. First, since the anti-slip member is embedded in the holding hole provided in the brake lever, even if the anti-slip member receives a dragging force toward the tip of the lever while it is acting to prevent fingers from slipping, It can resist this and remain in the holding hole. The same can be said of the case where strong braking is performed by placing one's fingers on the area where the anti-slip portion is formed. That is, the anti-slip member according to the present invention does not come off easily even if the braking operation is repeated, compared to, for example, a case where the anti-slip member is attached to a lever. Next, since the anti-slip member is embedded in the holding hole, the thickness of the anti-slip member itself can be increased. In this way, even if the lever is slightly protruded from the surface of the lever in its natural state, it can be sufficiently compressed and deformed during sudden braking operations to be buried in the holding hole. Therefore, there is no discomfort or pain when gripping strongly due to the presence of the protrusions.
Very easy to use. Furthermore, in the present invention, since the anti-slip member is embedded flush with the lever surface or in a slightly raised shape, the anti-slip member does not greatly affect the appearance of the brake lever itself, which is preferable in the past. Appearance can be maintained. As described above, according to the brake lever of the present invention, it is possible to effectively prevent fingers from slipping from the brake lever without deteriorating the usability or appearance of the brake lever, allowing safe and reliable brake operation. There are effects that can be done.

[Explanation of Examples]

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view of a brake lever to which the present invention is applied. The brake lever 1 is rotatably attached to a brake bracket 6 that is attached to the front of the U-shaped curved portion at both ends of the drop handle so as to protrude forward. . The brake lever 1 itself is made of a light metal such as aluminum, and has a smooth surface. A pair of elongated holding holes 4, 4 formed at the tip 2 of the brake lever are fitted with an anti-slip member 3 made of rubber or soft synthetic resin, the surface of which is slightly raised from the surface of the brake lever. It is buried in such a way. 2 and 3 show a first embodiment of the embedding structure of the anti-slip member 3. FIG. That is, in this example,
This is an example in which the invention of the present application is applied to a brake lever 1 whose cross section at the tip end is approximately U-shaped. Both end portions 3a, 3a of the anti-slip member 3 are respectively fitted into the pair of holding holes 4, 4 from the back side of the brake lever, and its surface portion is slightly raised from the holding holes 4, 4. 4 and 5 show a second embodiment of the embedding structure of the anti-slip member 3. FIG. That is, in this example,
This is an example in which the present invention is applied to a brake lever 1 whose tip end has a closed cross section. In such a brake lever, as shown in phantom lines in FIG. 4, the narrow portion 2a between the holding holes 4, 4 is curved and raised outward when the lever is formed, and the anti-slip member 3 is After inserting it between the holding holes 4, 4 so that both ends 3b, 3b are exposed, the narrow part 2
By pressing and deforming a to the general surface of the lever, the anti-slip member 3 is fixed in a deformed state. In the above configuration, since the anti-slip member 3 itself is made of rubber or soft synthetic resin that has a high frictional resistance against the skin, the anti-slip member 3 is flush with or slightly flush with the retaining holes 4 of the brake lever. The exposed raised anti-slip portion provides an effective anti-slip effect for fingers touching the brake lever. In addition, even if a strong dragging force is applied during sudden braking, the anti-slip member can resist this and remain in the holding hole, so it can be used even if the passenger's fingers are frequently touched by a strong pressing force. Regardless, inconveniences such as when the anti-slip member comes off the lever cannot occur. In addition, the anti-slip member 3, which has a large portion embedded in the holding hole, has a relatively large thickness and can be sufficiently compressed and deformed even when compressive force is applied. It can be deformed by compressing force so as to be embedded in the holding hole. Therefore, the occupant does not feel any discomfort as if being hit by a protruding object, nor does he feel any pain, making it extremely comfortable to use. Furthermore, the anti-slip member does not adversely affect the appearance of the brake lever. Of course, the invention is not limited to the embodiments described above. For example, the formation position of the holding hole is not limited to the illustrated example, but may be formed at the tip of the brake lever,
That is, it may be formed at any location located toward the distal end of the longitudinal center of the lever. Also,
Of course, the shape of the holding hole is not limited to the pair of elongated holes as shown in the illustrated example.
