Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brake lever device mainly used for bicycles.

As is well known, in this type of brake lever device, a lever is rotatably attached to a bracket fixed to a handle via a pivot shaft, and a rim brake device or the like is interlocked and connected to the lever via a Bowden wire. The brake device is configured to be operated by rotating the lever. However, in recent years, deformed handles with shapes bent at various angles have appeared on the market, and especially in the case of deformed handles with a short grip part, it is necessary to attach a brake lever device to the bent part of the handle. First, it is difficult to align the direction of the lever with the grip of the handle, and the distance between the grip of the handle and the lever becomes wider or narrower, making it difficult to mount the lever in an optimal manner. The drawback was that the state could not be obtained. Therefore, levers and the like are usually bent at different angles to match handles of various shapes. However, production of levers of various shapes has the drawback of poor production efficiency and high costs.

Therefore, in view of the above-mentioned problems, the present invention provides a handle that can be adapted to handles of various shapes.The feature of this invention is that the lever 1 rotates relative to the pivot shaft 4 provided on the bracket 3. A bolt 2 is freely pivoted and is held penetratingly on a pivot shaft 4.
3, a fastening band 1 that holds the circumferential surface of the handle 6;
In a brake lever device in which a bracket 3 is fixed to a handle 6 by screwing the bracket 3 into a nut 21 which is locked across both ends of a lever 9 so as to be reciprocatable, the bracket 3 is attached to a pivot having a pivot shaft 4. The bolts 23 are attached to the receiving side bracket part 13 and the fixed side bracket part 14 on the side fixed to the handle 6.
The two bracket parts 13 and 14 are divided by a plane perpendicular to the axis of the two bracket parts 13 and 14 in order to restrict relative rotation about the axis of the bolt 23 of the pivoting side bracket part 13 with respect to the fixed side bracket part 14. Engaging parts 17 and 18 that engage with the divided parts so as to be able to approach and separate from each other
are respectively provided around the axis of the bolt 23, and by screwing the bolt 23 back and forth freely, the engaging portion 1
7 and 18 are interlocked with each other, and the fixed side bracket part 14 and the pivotable side bracket part 13 are releasably fixed to the handle 6 side.

It consists of a pivoting side bracket part 13 having a pivot shaft 4 to which the lever 1 is pivoted, and a fixed side bracket part 14 fixed to the handle 6, with the divided parts of each bracket part 13 and 14 facing each other. As shown in FIG. 3, each of the opposing surface parts 15 and 16 is formed into a perfect circular shape in a plan view, and has chrysanthemum seats 17 and 18 as engaging parts that engage with each other so as to be able to move toward and away from each other through relative rotation. It is formed. This bracket 3 is fixed to the handle 6 by a fastening band 19. The fastening band 19 is a band-shaped body made of a thin steel plate, and holds the circumferential surface of the handle 6.
A nut 2 is inserted into the locking holes 20, 20 at both ends of the band 19.
Lock the ears 22, 22 at both ends of nut 2,
1, both ends of the band 19 are inserted into the fixed side bracket part 14 through the lower opening 5. A bolt 23 is passed through the pivot shaft 4 of the pivot side bracket part 13 in the diametrical direction, and the bolt 23 is attached to the opposing surface parts 15, 16 of the respective bracket parts 13, 14.
It penetrates through the center and is screwed into the nut 21 so that it can move forward and backward. Here, both the bracket parts 13 and 14 are divided by a plane perpendicular to the axis of the bolt 23. Then, rotate the lever 1, insert a screwdriver into the gap between the lever 1 and the pivot bracket part 13, rotate the bolt 23, screw the bolt 23 into the nut 21, and fix the nut 21. By drawing it into the side bracket part 14, the opposing surface parts 15,1 of each bracket part 13,14
6 are pressed into tight contact with each other, and a band 19 is fastened onto the handle 6.

24 is a bearing member, which connects the pivot shaft 4 and the lever 1.
The lever 1 is interposed between the lever 1 and the base 2 of the lever 1, thereby making the rotation operation of the lever 1 smoother.

The embodiment of the present invention is constructed as described above, and when it is installed, the tightening band 19 is held by the handle 6 and the bolt 23 is screwed into the nut 21, as in the conventional case. At this time, since the bracket 3 is divided into a pivoting side bracket part 13 and a fixed side bracket part 14, the handle 6
In order to make the lever 1 correspond to the bending direction of
As shown by the imaginary line in FIG. 3, the bolt 23 may be relatively rotated around the axis of the bolt 23 and adjusted to a desired orientation, and then the bolt 23 may be fastened. As described above, the direction of the lever 1 can be freely adjusted through the relative rotation of the opposing surfaces 15 and 16 of the fixed side bracket part 14 and the pivotable side bracket part 13.
The optimum mounting condition can be easily obtained depending on the bending direction and the curve of the mounting position, and the lever 1 can be easily operated and safety can be improved. In addition, since the direction of the lever 1 can be adjusted freely, it can also be used as a deformable handle 6 that is bent at various angles.
