Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a brake lever that is attached to a bicycle handlebar or the like.

<Conventional technology> Conventionally, as a bicycle brake lever,
As shown in Japanese Patent No. 58-49903, there was one constructed by a combination of a metal plate and a synthetic resin.
That is, by drawing a metal plate, an operating section arm section having a substantially C-shaped cross section and a pivot joint section having a substantially U-shaped cross section are integrally formed into a substantially L-shape; It was constructed by fitting an insert member made of synthetic resin.

<Problems to be solved by the invention> According to the above configuration, the metal plate must be drawn into a complicated shape, and correspondingly, the shape of the insert member made of synthetic resin is also complicated. The disadvantage was that it became difficult to process.

Therefore, in view of the above-mentioned problems, the present invention aims to provide a device that has a simple structure and is easy to manufacture.

<Means for solving the problem> The technical means includes pivot parts 11, 15, 16 rotatably connected via a pivot to a mounting housing 1 fixed to a handle at one end. , operation arm parts 12, 17, 18 for rotation operation at the other end.
In the substantially L-shaped brake lever 6, the brake lever 6 is made of synthetic resin and has a connecting part to which the fixed terminal 24 at the end of the inner wire 23 of the Bowden wire 4 is connected and supported at the intermediate corner parts 10, 13, 14. The lever body 7 formed in the substantially L shape is overlapped with both sides of the pivot portion 11 of the lever body 7, and is fitted into the recesses 29 formed on both sides of the operating arm portion 12 of the lever body 7, respectively. Pivot holes 20, 21, 22 through which the pivot shaft 19 passes are formed in both the reinforcing metal plates 8, 9 and the lever body 7, Support holes 25 and 26 for supporting both ends of the fixed terminal 24 are formed in the plates 8 and 9, respectively.

<Embodiment> Hereinafter, an embodiment of the present invention will be described based on the drawings. In FIGS. 1 to 4, reference numeral 1 denotes a mounting housing fixed to the handle;
An outer holder 3 is supported by a boss 2 formed on the front wall of the holder, and an end portion of an outer wire 5 of a Bowden wire 4 is received by the outer holder 3.

Reference numeral 6 denotes a brake lever, which includes a lever main body 7 formed of synthetic resin into a substantially L-shape, and reinforcing metal plates 8 and 9 formed into a substantially L-shape by metal plates such as iron plates provided on both sides of the lever main body 7. It consists of

The lever body 7 has one corner portion 10 as a pivot portion 11 which is pivotally connected to the housing 1;
The other end is configured as an operating arm section 12 for rotational operation. In addition, each of the reinforcing metal plates 8 and 9 similarly connects one of the corner portions 13 and 14 to the pivot portions 15 and 16.
The other is configured as operating arm portions 17 and 18. And the lever body 7 and each reinforcing metal plate 8,
Pivot holes 20, 21, 22 are formed in each of the pivot parts 11, 15, 16 of 9, through which a pivot shaft 19 such as a mounting bolt passes. Further, in the corner portions 13 and 14 of each of the reinforcing metal plates 8 and 9, support holes 2 are provided as connecting portions for relatively rotatably supporting both ends of the fixed terminal 24 provided at the end of the inner wire 23.
5 and 26 are formed. An insertion groove 27 for inserting the inner wire 23 is formed in the support hole 25 of one reinforcing metal plate 8 in a continuous manner. Furthermore, an avoidance notch 28 is formed in the corner portion 10 of the lever body 7 in order to avoid the fixed terminal 24. In addition, in order to fit the operating arms 17 and 18 of each reinforcing metal plate 8 and 9 into both sides of the lever body 7,
Recesses 29 are respectively formed. and each recess 2
The bottom surface of 9 and the side surface of the pivot portion 11 are on the same plane. Then, reinforcing metal plates 8 and 9 are superposed on both sides of the lever body 7, respectively, and reinforcing metal plates 8,
Each of the operating arm parts 17 and 18 of 9 is fitted into each recessed part 29, and each of the operating arm parts 12, 17, 18
It is integrally fixed by a fixing member 33 such as a rivet that is inserted through insertion holes 30, 31, and 32 formed in the.

The embodiment of the present invention is constructed as described above, and each reinforcing metal plate 8, 9 on both sides is flat plate-like, and approximately L
It is shaped like a letter, has a simple shape and structure, does not require complicated processing, and can be easily manufactured by simple punching or the like. Furthermore, the lever main body 7 has a simple shape and structure, and can be easily manufactured. From the above, the brake lever 7 can be easily manufactured and provided at low cost. In addition, the reinforcing metal plate 8,
The nine edges do not touch the hands directly, making it safe and giving a good feel to the hands. Furthermore, by exposing the outer surfaces of the operating arms 17, 18 of the reinforcing metal plates 8, 9 on both sides of the brake lever 7, the design can be improved.

<Effects of the invention> According to the invention, the brake lever is made of a synthetic resin and is formed into a substantially L-shaped lever body, which is superimposed on both sides of the pivoting part of the lever body. Consisting of approximately L-shaped reinforcing metal plates fitted into recesses formed on both sides,
Both reinforcing metal plates and the lever body have a pivot hole through which the pivot shaft passes, and both reinforcing metal plates have support holes that support both ends of the fixed terminal, so the shape and structure are simple. , it does not require any complicated processing, can be easily manufactured by simple processing, and can be provided at low cost. Furthermore, it has the advantage of improving safety and design.
