Description

本考案は、車両の窓ガラス等の拭掃に使用するワイパー装置において、先端がＵ字形状に湾曲して形成されたワイパーアームに対するワイパーブレードの結合機構に関する。 The present invention relates to a wiper blade coupling mechanism to a wiper arm having a tip curved in a U shape in a wiper device used for wiping a window glass or the like of a vehicle.

実公平３−４９０８１号公報では、図１５に示すように先端がＵ字形をなすワイパーアーム１がワイパーブレード１０１に設けた第１のピン１０２によって回動可能に支持され、前記ワイパーアーム１のＵ字形部１１の内面に補完的な支持表面を有する支持部材１０３と、ワイパーアーム１の長手方向前方に前記第１のピン１０２から間隔をおかれた第２のピン１０４によって回動可能に支持され前記支持部材１０３に支持されたワイパーアーム１のＵ字形部１１の外面湾曲部１２にほぼ補完的な抑留表面１０５を有し、前記抑留表面１０５の一部が弾性的に前記外面湾曲部１２から離れる方向に屈撓可能となされている抑留部材１０６（蓋部材）と有する構成が開示されている。 In Japanese Utility Model Publication No. 3-49081, a wiper arm 1 having a U-shaped tip is rotatably supported by a first pin 102 provided on the wiper blade 101 as shown in FIG. A support member 103 having a complementary support surface on the inner surface of the character-shaped portion 11 and a second pin 104 spaced from the first pin 102 in the longitudinal direction of the wiper arm 1 are rotatably supported. A retaining surface 105 that is substantially complementary to the outer curved portion 12 of the U-shaped portion 11 of the wiper arm 1 supported by the support member 103 is provided, and a part of the retaining surface 105 elastically extends from the outer curved portion 12. The structure which has the restraining member 106 (lid member) made to be able to bend in the direction to leave | separate is disclosed.

しかしながら、前記ワイパーアームは、複数の規格サイズ（９×４：Ｕ字形状部の幅９ｍｍ、上下方向の内寸法１０．７ｍｍ、肉厚４ｍｍ、９×３．５：Ｕ字形状部の幅９ｍｍ、上下方向の内寸法６．７ｍｍ、肉厚３．５ｍｍ、９×３：Ｕ字形状部の幅９ｍｍ、上下方向の内寸法６．７ｍｍ、肉厚３ｍｍ）が存在するため、従来の支持部材と抑留部材（蓋部材）を使った固定方法では、１つの支持部材で９×３の規格サイズと９×３．５の規格サイズだけ対応するか、あるいは各々、前記ワイパーアームのＵ字形部分のサイズに対応した専用の支持部材を必要としており、図１６に示す９×４の規格のサイズのワイパーアーム１ａを固定する９×４の規格サイズ用の支持部材１０３ａに、９×３の規格サイズのワイパーアーム１ｃを固定しようとすると、図１７に示すようにワイパーアーム１ｃのＵ字形部１１ｃの内面寸法の高さが足りず、逆に図１８に示す９×３の規格のサイズのワイパーアーム１ｃを固定する９×３の規格サイズ用の支持部材１０３ｃに、９×４の規格のサイズのワイパーアーム１ａを固定しようとすると、図１９に示すようにワイパーアーム１ａのＵ字形部１１ａの内面寸法の高さが余ってしまい、更に抑留部材１０６（蓋部材）とワイパーアーム１ａのＵ字形部１１ａの外面が干渉してしまうため、このような従来の構造では、１種類の支持部材で、少なくとも９×３の規格サイズのワイパーアームと９×４の規格のサイズのワイパーアームの両方に適合させることができなかった。 However, the wiper arm has a plurality of standard sizes (9 × 4: U-shaped portion width 9 mm, vertical inner dimension 10.7 mm, wall thickness 4 mm, 9 × 3.5: U-shaped portion width 9 mm. , The inner dimension in the vertical direction is 6.7 mm, the wall thickness is 3.5 mm, 9 × 3: the width of the U-shaped portion is 9 mm, the inner dimension in the vertical direction is 6.7 mm, and the wall thickness is 3 mm. And a fixing method using a detention member (lid member), a single support member supports only a standard size of 9 × 3 and a standard size of 9 × 3.5, or each of the U-shaped portions of the wiper arm. A special support member corresponding to the size is required, and the 9 × 4 standard size support member 103a for fixing the 9 × 4 standard size wiper arm 1a shown in FIG. Trying to fix the wiper arm 1c Then, as shown in FIG. 17, the inner dimension of the U-shaped portion 11c of the wiper arm 1c is insufficient, and conversely, the 9 × 3 standard size wiper arm 1c shown in FIG. 18 is fixed. When trying to fix the wiper arm 1a having the standard size of 9 × 4 to the support member 103c for the standard size, the height of the inner surface of the U-shaped portion 11a of the wiper arm 1a is excessive as shown in FIG. In addition, since the retaining member 106 (lid member) and the outer surface of the U-shaped portion 11a of the wiper arm 1a interfere with each other, in such a conventional structure, a standard size of at least 9 × 3 is required with one type of support member. And a 9 × 4 standard size wiper arm could not be adapted.
