Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel balance weight used for a wheel having a hub and a rim connected by a plurality of spokes.

[0002]

2. Description of the Related Art Generally, a balance weight for a wheel is of a type in which a lead weight is crushed and attached to a wheel.
It is difficult to reuse the lead weight once attached to the wheel. From the viewpoint of resource saving, it is preferable that the balance weight for wheels can be reused.

[0003] As a balance weight for wheels, for example, Japanese Unexamined Utility Model Publication No. Sho 63-22201, "Balance Weight for Wheels" is known. According to FIG. 1 of the publication, the above-mentioned technique is based on a wheel balance weight adapted to be attached to a spoke 5 (hereinafter referred to as a “disk portion”) of an aluminum wheel 4 (the reference numeral is used in the publication). And
It comprises a fixture 6 attached to the disk portion and a balance weight 1 integrally attached to the fixture 6.

[0004]

The above-described wheel balance weight is provided with the fixture 6, so that the balance weight 1 removed from the aluminum wheel 4 can be reused. However, in the above-described wheel balance weight, since the disc portion has a variety of shapes in terms of design, a dedicated mounting tool is required every time the aluminum wheel design changes. Further, the above-described wheel balance weight cannot be attached to a wheel having a rim connected to a hub by a plurality of wire spokes. That is, a versatile wheel balance weight suitable for balancing a wheel having a rim connected to a hub by a plurality of wire spokes is desired.

It is an object of the present invention to provide a versatile wheel balance weight suitable for balancing a wheel having a rim connected to a hub by a plurality of wire spokes.

[0006]

According to a first aspect of the present invention, there is provided a wheel balance weight for connecting a hub and a rim with a plurality of spokes, and attaching a balance weight to one or a few spokes. In order to attach the spokes to the rim, the left half weight and the right half weight, and the left half weight and the right half weight attached to the nipple inserted into the rim to attach the spokes to the rim, And a detachable clip for inserting the clip.

[0007] A left half weight and a right half weight are applied to the spokes or nipples from the left and right, and the left half weight and the right half weight are sandwiched by clips to be stopped by the spokes or the nipples. In a wheel in which a hub and a rim are connected by a plurality of spokes, it is conceivable to attach a balance weight to the spoke or a nipple inserted into the rim to attach the spoke to the rim in order to balance the wheel. Therefore, the balance weight is composed of a left half weight and a right half weight, and a clip for sandwiching the left half weight and the right half weight, for example, even for wheels having different diameters of spokes and nipples. Be ready for mounting.
