Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to improvements in a brake lever mounting device used for bicycles.

Conventionally, as shown in FIG. 6, in a mounting device for mounting a bicycle brake lever on a handlebar, a brake lever 1 is rotatably attached to a housing 4 with bolts 2, nuts 3, etc. The handle 7 was held by the arcuate mounting base 5 and the semicircular band member 6, and was configured to be tightened with bolts 8 and nuts 9. However, the locking portion 1 where one end of the band body 6 is locked on one circumferential end side of the mounting base 5 of the housing 4
0 and a flange portion 11 that is secured to the other end of the band body 6 and bolts 8 and nuts 9 at the other end in the circumferential direction, making it an asymmetrical shape. The disadvantage was that production efficiency was poor.

Therefore, in view of the above problems, the present invention aims to improve the productivity of the housing by making the housing compatible with both the left and right sides.The features of this invention are as follows.
In a brake lever mounting device in which a housing in which a brake lever is rotatably mounted is fixed to a handle using a dedicated mounting member, the mounting member is inserted through an insertion hole formed in a mounting base of the housing to attach the handle. A band body to be held, a connecting body connecting both ends of the band body, and a cover body that covers the connecting body and comes into contact with the outer circumferential side of the handle;
The pulling body is screwed onto the connecting body from the outside of the cover body and pulls the connecting body radially outward of the handle by rotating the outer portion of the pulling body.

Hereinafter, embodiments of the present invention will be described based on the drawings. In FIGS. 1 to 4, reference numeral 20 denotes a brake lever, which is formed of a light alloy into a substantially L-shape. Then, the base 21 of the brake lever 20 is inserted into the housing 22, and the bolt 23
It is rotatably connected to the housing 22 by a nut 24. Further, an outer support 26 is supported by a boss 25 formed on the front wall of the housing 22,
The outer wire 28 end of the Bowden wire 27 is received by the outer receiver 26 . In addition, the inner wire 29 of the Bowden wire 27 is
A fixed terminal 30 is inserted into the housing 22 through the wire 6 and provided at the end of the inner wire 29.
is supported in a mounting hole 31 formed in the brake lever 20 so as to be relatively rotatable.

As shown in FIGS. 2 and 3, band members 33 are provided on both side walls of the mounting base 32 of the housing 22.
An insertion hole 34 is formed through which the handle 35 is inserted, and the edges of the attachment base 32 are widened from each other so as to be attached along the outer peripheral surface of the handle 35. The band body 33 is a band-shaped body made of a thin steel plate, and is inserted through both insertion holes 34, 34 of the housing 22 to hold the handle 35. Also, the band body 33
A locking hole 37 is formed in both ends 36, 36 of the band body 33, and a locking protrusion 39 is formed protrudingly at both ends of a nut body 38 serving as a connecting body that connects both ends 36, 36 of the band body 33. , 39 are each locking hole 3
7 and 37, respectively. A box-shaped metal cover body 40 is provided to cover both ends 36, 36 of the band body 33 and the nut body 38, and is inserted into a fitting hole 42 formed in a bottom wall 41 of the cover body 40 as a pulling body. The shaft portion 44 of the bolt body 43 is fitted, and the male thread 45 of the shaft portion 44 and the nut body 3
8 female screws 46 are screwed together. Then, by rotating the bolt body 43, the nut body 38 is pulled toward the bottom wall 41 of the cover body 40, that is, toward the outside in the radial direction of the handle 35, thereby tightening the band body 33 onto the handle 35. The housing 22 is then fixed to the handle 35. The band body 33, nut body 38, cover body 40, and bolt body 43 constitute a mounting member for fixing the housing 22 to the handle 35.

The embodiment of the present invention is constructed as described above, and the band body 33 and the nut body 38 form an annular shape that holds the handle 35, and the band body 33 is tightened by rotating the bolt body 43. If the bolt body 40 is loosened, the position of the cover body 40 etc. can be freely moved in the circumferential direction of the handle 35, as shown by the imaginary line arrows in FIGS.
3 can be rotated to tighten the band body 33. Therefore, the cover body 4 should be placed in a position that will not interfere with the installation or operation of bicycle accessories such as a buzzer.
0, the position of the bolt body 43, etc. can be set, and it is easy to use. Moreover, by rotating the bolt body 43 on the outside of the cover body 40, tightening and loosening can be easily performed from the outside, resulting in good operability. In addition, the housing 22 has through holes 3 on both side walls of the mounting base 32.
4, 34, and a second
As shown in the figure, since the cover body 40 etc. can be set at any position in the circumferential direction of the handle 35, the housing 22 and the band body 3 have the same shape.
3. Nut body 38, cover body 40 and bolt body 4
All three components can be used commonly for both the left and right sides, which improves productivity and can be provided at low cost. Furthermore, since the structure is such that both ends 36, 36 of the band body 33 and the nut body 38 are covered with the cover body 40, collisions from the outside can be prevented, and damage to the both ends 36, 36 and the nut body 38 can be prevented. The aesthetic appearance can be improved compared to the conventional structure in which the bolts 8 and nuts 9 are exposed to the outside. Also, normally, these cover bodies 40 and the like are installed below the handle 35 so as not to cause any trouble, but if they are installed above the handle 35, dirt and dust will not enter into the cover body 40. can be prevented and durability can be improved.

In the above embodiment, the nut body 38 and the band body 33 are shown as separate bodies, but the nut body 38 may be integrated with the band body 33 by welding or the like. Further, as shown in FIG. 5, a bolt body 47 is used as a connecting body connecting both ends 36, 36 of the band body 33, and a nut body 4 is used as a pulling body.
It may have a structure of 8. Furthermore, cover body 4
0 may be formed of resin, and its shape is not limited to the shape of the embodiment.

As described above, the present invention includes a mounting member that fixes a housing to which a brake lever is pivotally mounted, a band body that inserts through an insertion hole formed in a mounting base of the housing and holds a handlebar, and a band body that holds a handlebar by passing through an insertion hole formed in a mounting base of the housing. A connecting body that connects both ends, a cover body that covers the connecting body and comes into contact with the outer circumferential side of the handle, and a connecting body that is screwed onto the connecting body from the outside of the cover body and is rotated by rotating the outer portion of the cover body. and a traction body that pulls the handle radially outward. The position of the cover body etc. can be set at the desired position in the circumferential direction of the handle.
Easy to use. In addition, the structure is such that the portion of the traction body located outside the cover body is rotated, so that tightening and loosening can be easily performed outside the cover body, resulting in good operability. In addition, each mounting member and housing can be used commonly for the left and right sides, so productivity can be improved and the product can be provided at low cost. Further, there are advantages in that it is possible to prevent damage to both ends of the band body and the connecting body, and also to improve aesthetic appearance.
