[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a bicycle stand.

[0002]

2. Description of the Related Art Conventionally, when mounting a bicycle stand, a mounting hole is formed in a flat surface of a stand mounting piece of a support fitting fastened to a rear wheel axle portion, and a mounting hole formed in the mounting hole and an end of the stand. The hole and the stud are pivotally connected.

[0003]

However, the stand mounting piece of the prior art described above has only a flat surface provided with a mounting hole, and the flat portion of the stand is slid along the flat hole to caulk the two with studs. It is pivoted freely with swing.
In other words, the stability of the stand and the stand mounting piece depends only on the dimensional accuracy of the stud and the mounting hole for receiving the stud. In use, a shear stress acts directly on the stud, and therefore, the frequent use of the stand. Due to this, the mounting holes of the stand mounting piece and the stand expand due to wear and the operation becomes unstable,
In addition, as the hole diameter increases, the wear rate is synergistically accelerated, and with this, the tack also progresses in wear,
Eventually, they will fall off unintentionally. An object of the present invention is to solve the above-mentioned drawbacks of the conventional example and to provide a stand mounting structure that can operate stably for a long period of time.

[0004]

According to the present invention, there is provided a bicycle stand mounting apparatus comprising: a stand supporting bracket attached to a rear wheel axle of a bicycle; and a rod-shaped stand rotatably attached to the stand supporting bracket with studs. The stand support has a stand mounting hole through which a stud can be inserted at a predetermined position, and an annular protruding edge is formed on one side edge of the stand mounting hole, and the stand has a flat upper end. A recess having an arc-shaped inner surface at which at least a half-peripheral outer surface of the protruding edge is in contact with the flat portion, and a mounting hole through which a rivet can be inserted is provided at the bottom of the recess. And

[0005]

The annular protrusion provided on the stand support and the recess provided on the stand act to position the stand when the stand is fastened to the stand support. After the rivet is fastened, the annular protruding edge acts as a rotating shaft to prevent rattling of the stand and prevent a shear force from being applied to the rivet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the drawings. As shown in FIGS.
By inserting and tightening the axle 13 from zero ,
The support bracket 1 is fixed to the rear wheel axle of the bicycle , a stand mounting hole 3 is formed in the stand mounting piece 2 of the support bracket 1, and an annular protruding edge is formed on one side edge of the mounting hole 3. A U-shaped recess 6 is formed on one side of the flat portion 5 formed at the upper end of the stand 11 which is formed on the other side of the rod and is open toward the upper end, and a mounting hole 7 is formed at the bottom of the recess 6. And the recess 6 is formed in an arcuate inner surface with which the outer surface of the protruding edge 4 contacts.
Shall have a 6a, concave to the flange 4 stand 11
In a state of being located at the 6, tacks 8 is inserted towards the mounting hole 3 and 7 from one side surface of the stand mounting piece 2 as shown in FIG. 2, by crimping one kick the projecting end of該鋲8 The stand 11 is swingably held. In addition, the code | symbol 9 in a figure shows a spring hooking piece, 12 shows a lock fitting.

Next, the operation will be described. Since the stand 11 is stably held on the mounting piece 2 of the supporting bracket 1 by mutual engagement with the annular ridge 4, the stand is not pivotally supported by only the studs, but the studs. Stand mounting piece 2 and stand 1
1, and mainly serves as a center of rotation by the annular protruding edge 4 and the recess 6 of the stand 11,
Since the stand is rotated, no shear stress is directly applied to the studs 8, the wear of the studs is reduced, and the operation is smooth and light because there is no surface contact as before.

Although the U-shaped recess 6 has been described above, the recess 6 has an arcuate inner surface 6a that contacts at least a half-circumferential outer surface of the protruding edge 4 provided on the stand support 1. As long as it has, it may be formed in a circular shape so as to be in contact with the entire outer surface of the protruding edge 4.

[0009]

[Effect of the Invention] In the present invention, the positional relationship between the annular protruding edge protruding from the stand mounting piece and the recess on the stand for receiving the same is determined.
Can be easily positioned, and the assembly workability is improved.
I do. Also, the stand pivots around the protruding edge.
Therefore , the shear force is not directly applied to the studs, and the studs due to the wear of the studs are not generated, and the operation is smooth, and at the same time, the operation is extremely light because there is no surface contact as in the conventional example. Further, the above-mentioned configuration makes it possible to maintain the initial operation characteristics over a long period of time when the wear progresses slowly.
