本考案は、ワイヤースポークホイールにおける
スポーク抜止め装置に関する。[Detailed Description of the Invention] The present invention relates to a spoke slip-out prevention device for a wire spoke wheel.

イヤースポークホイールが広く用いられている。 In two-wheeled vehicles such as motorcycles, various types of wheels are used to bear the weight of the vehicle, but wire spoke wheels are widely used because they are light and have excellent rigidity.

があつた。 In such a wire spoke wheel, one end of the wire spoke that is held on the hub side is generally bent at a substantially right angle and engaged with a mounting hole. However, in this case, loads are applied to the bent portions during driving, which can easily cause accidents such as loosening or breaking of the spokes. Therefore, a structure can be considered in which the load applied to the bent part of the spoke is reduced by attaching the spoke with a bending angle of about 15 to 35 degrees, but in this case, in the unlikely event that the spoke breaks, Then, the broken spoke is likely to fall off. For example, in the wire spoke wheels shown in FIGS. 1 and 2, a hub 2 that supports the heads 1a of the wire spokes 1 is combined with a panel 3. If the spoke 1 is broken, there is a risk that the broken spoke 1 may fall off from the head 1a side and become entangled with the wheel, or become stuck in the gap A between the hub 2 and the panel 3, causing an accident such as making the vehicle unable to drive. It was hot.

There is a known prior art technique (Japanese Patent Application Laid-open No. 86047/1983) in which the spokes are mounted and sandwiched between the spokes and the hub.
しかし、かかる先行技術では、スポーク穴を形

があり、好ましくない。 However, in this prior art, the presser foot also becomes part of the hub in order to form the spoke holes, so if the presser foot comes off, there is a risk that all the spokes will fall off, which is undesirable.

抜止め装置を提供することを目的とする。 The present invention solves the drawbacks of the prior art and provides a spoke slip-out prevention device for a wire spoke wheel that can prevent the spokes from falling off when they are broken, using only a spoke fixing ring without any special modifications to the hub. The purpose is to
以下、図示の実施例を参照しながら本考案を詳
細に部明する。 Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiments.

状に予め形成されている。 4 is a spoke mounting flange of the hub 2 that supports the head 1a of the wire spoke 1, and this spoke mounting flange 4 has a spoke mounting hole 4a for engaging the head 1a of the spoke 1 on the inside and outside of the spoke mounting flange 4. They are formed at predetermined intervals and at appropriate angles in the circumferential direction. Reference numeral 5 denotes a spoke fixing ring which is screwed onto the hub 2 via a screw 6 so as to lock the head 1a of the spoke 1 on the inner peripheral surface of the spoke attachment flange 4 on the panel 3 side. It is formed in advance into a thin ring shape that follows the shape of the spoke attachment flange 4 using a resin material.
しかして、本考案によると、走行時に、万一、

はない。 However, according to the present invention, when driving,
If the spoke 1 breaks, the head 1a of the spoke 1 is locked by the ring 5, so
There is no risk of spoke 1 falling out from the spoke mounting hole.

ブにそのまま適用することができる。 As described above, according to the spoke slip-out prevention device for wire spoke wheels of the present invention,
Even in the unlikely event that a spoke breaks while driving, there is no risk of the spoke falling out, which prevents accidents such as broken wire spokes becoming tangled in the wheel or caught between the hub and panel. It can be prevented. Furthermore, even if the spoke fixing ring should come off, it will not affect the support of the spokes, so it will have no effect on driving. Furthermore, since no changes are made to the structure of the hub, it can be applied to conventional hubs as is.
