Description

[Detailed description of the invention] This invention is an improvement on the rim brake foot holder for bicycles, and its purpose is to finely adjust the position of the rim brake adjustment plate into which the rim brake foot is inserted. The purpose of this is to prevent scratches caused by using a mounting band to attach the rim brake footrest to the front fork.

The rim brake is suspended by a rod supported by the handle at the upper end, and the rim brake foot located below the brake shoe at the lower end is inserted into the hole in the rim brake foot holder so that the brake shoe contacts the appropriate surface of the rim. It can be positioned to

Conventional rim brake foot rests are fixed to the left and right front forks with mounting bands, so when tightening the mounting bands or fine-tuning the position of the rim brake foot rests, you need to operate the tightening screw on the mounting band each time. It was necessary to do so, and there was a risk of damage to the front hawk.

Here, the present invention prevents scratches caused by the mounting band by welding the rim brake foot rest to the front fork, and also allows the adjustment of the proper position of the brake shoe of the rim brake by welding the rim brake foot rest to the front fork. The problem was solved by dividing the problem, and an example thereof will be described below with reference to the drawings.

In FIG. 1, 1 is a front fork, and 2 is a rim brake. Like the conventional product, the rim brake is supported by a lever supported by a handle (not shown) and a rim brake foot holder 4 into which a rim brake foot 3 is inserted. It is something to do.

The feature of the present invention is that the rim brake foot rest 4 is composed of two members, namely, a base 5 and an adjustment plate 6, of which the base 7 of the base 5 is welded and fixed to a predetermined position of the front fork 1.

The pedestal 5 consists of an upper plate 5a and a lower plate 5b, and has a U-shaped cross section, with a gap 8 and a screw hole 9 in the center passing through the upper and lower plates.
is provided.

Reference numeral 10 denotes a protruding portion extending forward from the upper and lower plates 5a and 5b, and this portion extends substantially orthogonally to the upper and lower plates 5a and 5b located in the horizontal direction, and has a hole 12 into which the adjustment bolt 11 is screwed.
is provided.

The adjustment plate 6 has an elongated plate shape, and has a hole 13 at one end into which the rim brake foot 4 is inserted, and the other end is inserted into the gap 8 of the pedestal 5 described above, and has an upper plate 5a and a lower plate. There are screw holes 14 corresponding to the screw holes 9 passing through 5b, and these screw holes 9
, 14 are screwed with connecting bolts 15 to rotatably connect the adjustment plate 6 to the base 5.

The positional relationship between the adjustment plate 6 and the protrusion 10 of the pedestal 5 is that of the protrusion 1
The tip of the adjustment bolt 11 screwed into the hole 12 of 0 faces and contacts the side surface 16 of the adjustment plate 6. By screwing in this adjustment bolt 11, the adjustment plate 6 is pushed and connected to the pedestal 5. It can be rotated laterally around a connecting bolt 15, which is a section.

The present invention is more powerful than the above structure, so when assembling, insert the rim brake foot 3 into the hole 13 of the adjustment plate 6, insert the adjustment plate 6 into the gap 8 of the pedestal 5, and then tighten the connecting bolt 15.
Fix both.

Then, by operating the brake lever, the position of the adjustment plate 6 is finely adjusted by fixing the adjustment bolt 11 screwed into the protrusion 10 so that the brake shoe contacts the proper position of the rim.

Therefore, with this invention, even if the pedestal is fixed to the front fork by welding, it is possible to finely adjust the position of the hole where the rim brake foot is inserted, and it is possible to prevent the front fork from being scratched by the mounting band. Since the adjustment plate can be moved laterally, assembly and adjustment of the rim brake can be easily performed.
