JPH04104001U - Spoke wheels for tubeless tires - Google Patents

Abstract

(57) [Summary] [Purpose] A tubeless tire that can maintain airtightness between the nipple hole of the rim and the nipple even if the spokes become bent or damaged, preventing air from escaping and making the tire unusable. Getting spoke wheels for. [Structure] The nipple is sealed with an O-ring into the nipple hole of the rim, and the nipple is inserted, the tip of the spoke is screwed into the screw hole of the nipple, and the nut screwed around the outer circumference of the nipple is crimped onto the rim.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was applied to spoke wheels for tubeless tires used on motorcycles, etc. related.

0002

[Conventional technology]

Spoke wheels, which connect the rim and hub with spokes, are inserted into the nipple holes of the rim. There is a gap between the nipple to be inserted and the threaded part of the spoke that screws into the nipple, so Generally, tires with tubes are used. Trying to use tubeless tires Then, seal between the nipple hole of the rim and the nipple with an O-ring, and tighten the nipple screw. Closing one end of the hole to make it airtight allows the air injected into the tubeless tire to flow from the rim side. I try not to leak it. For example, see Japanese Patent Application Laid-Open No. 60-38201.

0003

[Problem that the idea aims to solve]

A spoked wheel has a rim supported by many spokes. And even just one spot If the rim becomes loose due to bending or damage, a gap will form between the nipple hole in the rim and the nipple. This causes air to leak, resulting in a problem that makes it unusable.

0004 In view of this, this invention is designed to prevent spokes from bending or breaking. However, the airtightness between the nipple hole of the rim and the nipple can be maintained, allowing air to escape and making it usable. The aim is to obtain spoked wheels for tubeless tires that can prevent them from becoming loose. target

[0005]

[Means to solve the problem]

In order to achieve the above purpose, this invention is aimed at spoke wheels for tubeless tires. Insert the nipple into the nipple hole of the rim by sealing it with an O-ring, and then tighten the nipple screw. Screw the tip of the spoke into the nipple hole, and crimp the nut screwed onto the outer circumference of the nipple to the rim. It's what I did.

[0006]

[Effect]

Even if the spoke is bent or damaged by a flying stone, the nipple can be replaced with a nut. Since it is fixed to the rim, it is possible to maintain an airtight seal between the rim and the nipple. Air in the breath tire can be prevented from leaking.

【Example】

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. The rim 1 is provided with a nipple hole 2 in its center. Nipple 3 is bolt-shaped The screw hole 4 is bottomed to prevent air from passing through. Ni The pull 3 is sealed by sandwiching the O-ring 5 between it and the nipple hole 2 of the rim 1. into hole 2. Then, insert the screw 7 at the tip of the spoke 6 into the screw hole 4 of the nipple 3. Screw on and tighten. Pass the nut 8 through the spoke 6 in advance, and then After screwing onto the nipple 3, screw the nut 8 onto the screw 9 provided on the outer periphery of the nipple 3. and press the nut 8 onto the rim 1. Nipple 3 can also be turned with a wrench from the tip side. A width across flats of 10 is provided as shown in FIG.

[0008] Even if the spokes 6 become loose or broken, the nipples 3 are attached to the nuts 8. Since it is fixed to rim 1, O seals nipple 3 and nipple hole 2. The ring 5 part does not loosen and maintains airtightness, eliminating the air inside the tubeless tire. It will not leak and become unusable.

[0009]

[Effect of the idea]

As explained above, since this invention is constructed as described above, the nipple is The spokes are fixed to the rim with a nut screwed around the outer circumference of the spokes, so there is no chance of the spokes coming loose. The nipple is fixed to the rim even if it breaks, ensuring an airtight seal between the rim and the nipple. This will prevent the air inside the tubeless tire from leaking and making it unusable. can be prevented.
