【考案の詳細な説明】
本考案は、車輪用リム、特にオートバイに用い
られるリムにおけるタイヤ滑止め装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tire anti-slip device for a wheel rim, particularly a rim used for a motorcycle.
従来、オートバイ用リム１は、第１図に示すよ
うに、両耳部１ａの内側面に多数の条痕２を刻設
し、該条痕２によりタイヤの滑りを防止してい
た。しかし、該条痕２は、平坦素材面にロールに

故が発生することがあつた。 Conventionally, motorcycle rims 1, as shown in Fig. 1, have numerous grooves 2 engraved on the inner surface of both ears 1a, and these grooves 2 prevent the tire from slipping. However, because these grooves 2 are formed by pressing the flat material surface with a roll, as shown in Fig. 2, their depth d is shallow and the groove surface is smooth, and furthermore the grooves 2 are formed recessed into the ear reference surface A having a predetermined width W. For this reason,
The streaks 2 do not bite into the tire sufficiently, and when a large sliding force acts between the rim 1 and the tire, as in motocross, the tire cannot withstand the sliding force and slips, losing tire torque, or the tire easily falls off in the event of a puncture, causing an accident.
そこで、本考案は、リム耳部内側面に所定長さ

有する駒を嵌合して、該爪をリム耳部基準面から
所定高さ突出して構成し、もつて前述欠点を解消
した車輪用リムにおけるタイヤ滑止め装置を提供
することを目的とするものである。 Therefore, in the present invention, a hole having a predetermined length is formed on the inner surface of the rim ear, and a piece having a claw with a sharp tip is fitted into the hole, and the claw is raised to a predetermined height from the reference plane of the rim ear. It is an object of the present invention to provide a tire slip prevention device for a wheel rim which has a protruding structure and eliminates the above-mentioned drawbacks.
以下、第３図ないし第５図に沿つて、本考案に
よる実施例を説明する。 Embodiments of the present invention will be described below with reference to FIGS. 3 to 5.

を穴６に嵌合した際、爪７ａが耳部基準面Ａから
所定高さｈ内方に突出する。 As shown in FIG. 3, the wheel rim 1 is made of aluminum alloy and includes an ear portion 1a, a bead seat portion 1b, and a drop portion 1c. And both ears 1a
A large number of tire anti-slip devices 5 are provided on the inner surface of the ear portion 1a at predetermined intervals to protrude inward, and the anti-slip devices 5 are provided on the inner surface of the ear portion 1a, as shown in FIG. It is composed of a rectangular hole 6 having a predetermined depth a and a predetermined length b, and a piece 7 that can fit into the hole 6. One end of the piece 7 has a rectangular shape that can be fitted into the hole 6, and the other end has claws 7a, 7a with sharply protruding tips, and the height H thereof is equal to that of the hole 6. The depth a is larger than the depth a by a predetermined amount, and therefore, as shown in FIG.
When fitted into the hole 6, the claw 7a protrudes inward from the ear reference plane A by a predetermined height h.

り所定高さｈ突出し、かつ鋭く突出している駒７
の爪７ａがタイヤビード部外側面に喰込む。 The piece 7 is formed by press punching a steel plate, and is further manufactured by subjecting it to a predetermined heat treatment. On the other hand, a large number of rectangular holes 6 are formed at predetermined intervals on the inner surface of the rim ear portion 1a in the manner of marking during rolling, and by fitting the pieces 7 into the holes 6, a tire anti-slip device 5 is constructed. be done. Then, when a tire (not shown) is mounted on the rim 1 and air is put into the tire, the outer surface of the bead of the tire is pressed against the rim ear 1a by the air pressure, and at this time, the outer surface of the bead of the tire is pressed against the rim ear 1a, at a predetermined height from the ear reference plane A. hProtruding and sharply protruding piece 7
The claw 7a bites into the outer surface of the tire bead.
なお、穴６への駒７の嵌合はかたい嵌合でな
く、弛い嵌合でも良い。この場合、駒７が穴６に

イヤと共に相対移動することはない。 Note that the fitting of the piece 7 into the hole 6 is not a hard fit, but may be a loose fit. In this case, since the piece 7 is fitted into the hole 6 to a predetermined depth a and the piece 7 has a predetermined width b', the piece 7 is pressed into the hole 6 by the tire, and the tire and rim 1 Even if a large sliding force acts between them, the piece 7 will not slip out of the hole 6 and move relative to the tire.

止め装置５を施すことができる。 As explained above, according to the present invention, a hole 6 having a predetermined length b is formed on the inner surface of the rim ear portion 1a, and a piece 7 having a sharp tipped claw 7a is fitted into the hole. Since the claw is configured to protrude by a predetermined height h from the rim ear reference plane A, the protruding height of the claw 7a can be increased and its shape can be formed sharply.
Coupled with the fact that the rim protrudes into the reference plane A of the rim ear, that is, the outside surface of the reference tire, the pawl 7a of the piece 7 is reliably bitten into the tire, and furthermore, the piece 7 does not come out from the hole 6. Even under severe usage conditions, the tire is surely prevented from slipping on the rim 1, tire torque can be maintained at all times, and the tire can be prevented from falling off the rim due to a puncture. Also,
The piece 7 can be easily manufactured by pressing or the like, and the hole 6 can be easily formed, and furthermore, when the piece 7 is fitted into the hole 6 made in the rim ear part 1a, it can be easily done by loose fitting etc. , the tire anti-slip device 5 can be provided extremely easily and inexpensively.
