Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fixing device for a sludge body and a sludge stay for a bicycle.

[Prior art]

Conventionally, as shown in FIG. 3, the muddy body and the muddy stay stay have a retainer 2 attached to the inner surface of the muddy body 1 and a recess 4a that accommodates a part of the muddy body stay 3. It is fixed by a fixture consisting of a bridge band 4 which is attached to the outer surface of the retainer 2 and connected to the retainer 2 by a machine screw 5 which is attached to the outer surface of the retainer 2, passes through a mounting hole 1a provided in the muddy body 1, and is fixed to a screw hole 2a provided in the retainer 2. ing. Therefore, when fixing (assembling) the muddy body 1 and the muddy stay 3, a great deal of effort is required and work efficiency is poor. In addition, the muddy body 1, retainer 2, muddy bed stay 3, and bridge band 4 are generally made of metal, and if there is a gap between the recess 4a of the bridge band 4 and the muddy bed stay 3, or if the machine screw 5 becomes loose, Abnormal noise due to vibration (metal contact sound)
may occur.

[Purpose of invention]

The present invention was devised in view of the above circumstances, and its purpose is to provide a fixing device for the sludge body and sludge stay that has good assembly workability and does not generate abnormal noises during running.

[Structure of the idea]

In order to achieve such an object, the present invention includes a base plate having a pair of holes corresponding to a pair of mounting holes provided in the bicycle's muddy body, and a base plate having a pair of holes corresponding to the holes of the base plate. a pair of wedge-shaped protrusions that protrude from one side of the substrate, expand outward toward the proximal end, have a wedge-shaped first protrusion capable of pinching the muddy body with the substrate, and expand inward toward the tip, facing each other; a synthetic resin retainer integrally provided with a pair of U-shaped protrusions having second protrusions, and a bridge piece having a recess in an intermediate portion for accommodating a part of a doryoke stay that supports the doyoke body;
A pair of legs protruding from one side of the bridge piece corresponding to the hole in the substrate and having a wedge-shaped third protrusion at the distal end that can be engaged with the second protrusion and expands toward the base end are integrated. It is constructed from a synthetic resin bridge band.

[Functions and effects of the idea]

If you use this fixing tool, first install the retainer into the mounting hole of the bridge band from one side of the pair of U-shaped protrusions, then insert a part of the cage stay into the recess of the bridge band and attach the legs of the bridge band. By inserting the retainer into a hole provided in the substrate of the retainer, the muddy body and the muddy stay can be fixed. Therefore, when attaching the retainer to the muddy body, the U-shaped protrusion temporarily bends inward, causing the first protrusion provided on the outside of the U-shaped projection to pass through the mounting hole of the muddy body. , the first protrusion is prevented from coming off by engaging with the sludge body,
The retainer is temporarily assembled into a loose body. In addition, when inserting the legs of the BridgeBand into the holes provided in the substrate of the retainer, the third protrusions provided on the legs temporarily push open the second protrusions provided on the U-shaped protrusion, and then pass through the second protrusions provided on the U-shaped protrusion. Engage with the protrusion. In such a state, the base plate of the retainer and the flat part of the bridge piece of the bridge band come into contact and clamp a part of the Doroyoke stay, and the legs are prevented from coming off against the U-shaped protrusion, and the U-shaped protrusion The pieces are expanded and prevented from coming off from the mounting hole, and the sludge body is held between the first protrusion provided on the U-shaped protrusion and the base plate, and the retainer is properly fixed to the sludge body and the bridge band to the retainer. be done.

In this manner, by using the fixing tool, it is possible to extremely easily fix the muddy body and the muddy stay, and the workability of assembling the muddy body and the muddy stay can be greatly improved. In addition, when the muddy body and the muddy stay are assembled using the fixing tool, the substrate of the synthetic resin retainer and the bridge piece of the synthetic resin bridge band sandwich the muddy stay and prevent contact between the muddy body and the muddy body. Therefore, problems caused by contact (occurrence of abnormal noise and wear) are prevented.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 shows a bicycle slip-on body 10, a slip-on stay 20, and a fixture 30 for connecting them. The muddy body 10 is made of a steel plate and is painted, and has a pair of mounting holes 10a.
is provided. The doroyoke stay 20 is made of steel rod and is plated, and the doroyoke body 10
It is formed in a U-shape.

The fixture 30 includes a retainer 31 made of synthetic resin and a bridge band 32 made of synthetic resin. The retainer 31 includes a base plate 31a having a pair of holes 31a1 corresponding to the mounting holes 10a of the sludge body 10, and a pair of U-shaped holes protruding from one side of the base plate 31a corresponding to the holes 31a1 of the base plate 31a. The projecting piece 31b is integrally provided. Each U-shaped protrusion 31b has a wedge-shaped first protrusion 31b1 that expands outward toward the base end (substrate 31a side) and can hold the muddy body 10 with the substrate 31a, and extends inward toward the tip. It has a pair of wedge-shaped second protrusions 31b2 that are enlarged and face each other. On the other hand, the bridge band 32 includes a bridge piece 32a which has a recess 32a1 in the middle part for accommodating a part (tip part) 20a of the droyoke stay 20, and this bridge piece 32a.
A pair of legs 32b are integrally provided on one side of the board 31a to protrude in correspondence with the holes 31a1 of the substrate 31a.
Each leg 32b has a wedge-shaped third projection 32b that can engage with the second projection 31b2 at the distal end and expands toward the base end.
