Description

【考案の詳細な説明】〔産業上の利用分野〕この考案はタイヤチエーン取付装置に関する。[Detailed explanation of the idea] [Industrial application field] This invention relates to a tire chain attachment device.

[Prior art]

自動車が雪上走行する場合、走行安定性を確保
する必要上、車輪にタイヤチエーンを設置するも
のある。 When automobiles drive on snow, tire chains are sometimes installed on the wheels in order to ensure running stability.

従来において、タイヤチエーンを車輪に設置す
るには、第６〜８図に示すような引掛部材１が使
用され、この引掛部材１のチエーン係止部３をサ
イドチエーンＳ（タイヤチエーンの一部）に掛け
止めし、且つ、バンド支持部５を環状弾性バンド
Ｂに掛け止めして、この環状弾性バンドＢの弾性
によりサイドチエーンＳを中心方向に引張ること
により車輪に固定していた。 Conventionally, in order to install a tire chain on a wheel, a hooking member 1 as shown in FIGS. At the same time, the band support part 5 was hooked to the annular elastic band B, and the side chain S was fixed to the wheel by being pulled toward the center by the elasticity of the annular elastic band B.

[Problems with conventional technology]

しかしながら、かかる従来の引掛部材１にあつ
ては、 (1) バンド支持部５の内壁面が滑らかであるた
め、弾性バンドＢがその軸方向に移動しやす
く、この結果、弾性バンドＢをタイヤチエーン
に設置しにくい、 (2) リブ９が基部の背面にあつたにすぎないた
め、引掛部材１の強度を充分に上げることはで
きない、という不都合を有した。 However, in the case of such a conventional hooking member 1, (1) Since the inner wall surface of the band support part 5 is smooth, the elastic band B easily moves in its axial direction, and as a result, the elastic band B is attached to the tire chain. (2) Since the ribs 9 are only attached to the back surface of the base, the strength of the hook member 1 cannot be sufficiently increased.

is connected to the side chain S via a hook member 15, and pulls the side chain S toward the center. In this way, since the elastic band B stretches the side chain S, the tire chain 13 is fixed to the wheel W.

次に、第２図〜第５図に基づいて、前記引掛部
材１５を詳述する。 Next, the hooking member 15 will be described in detail based on FIGS. 2 to 5.

る。 This chain locking portion 23 is a portion that is hooked to the side chain S. Reference numeral 25 denotes a retaining protrusion, which is formed at the tip of the chain locking portion 23. The cross section of this retaining protrusion 25 has a curved convex shape with respect to the side chain S attachment/detachment direction. Moreover, 27 is a band support part, which is integrally formed by curving the rear end of the base part 21. This band support portion 27 is a portion that is hooked onto the elastic band B. This band support part 27
is formed in a curved convex shape with respect to the longitudinal direction of the elastic band B. Therefore, the elastic band B can draw a smooth arc and come into close contact with the band support part 27.

２９は背面リブであり、基部２１の背面におい
てチエーン係止部側２３からバンド支持部２７側
方向に向かつて末広りの状態で一体形成されてい
る。この補強リブ２９は基部２１が長手方向に反

よつて、このタイヤチエーン取付装置を使用す
れば、弾性バンドＢがその軸方向に移動しにくく
なり、この結果、 (1) 弾性バンドＢのタイヤチエーンへの設置作業
がしやすい。 Therefore, if this tire chain attachment device is used, the elastic band B becomes difficult to move in its axial direction, and as a result, (1) the installation work of the elastic band B on the tire chain becomes easier;

(2) 引掛部材１の強度を充分に上げることができ
る。(2) The strength of the hook member 1 can be sufficiently increased.

(3) 弾性バンドはバンド支持部内で補強リブによ
つて押圧されるため、かかるバンド支持部から
