Abstract

PURPOSE:To extend the operating range of a wiper blade, by constituting it with an expandable arm, and controlling the wire cable connected to this arm. CONSTITUTION:A windshield wiper 2 consists of the part locked to a movable arm and another part housed in a blade guide 4, and a cable 3 for the movable arm and another cable 5 for the blade guide are connected. These cables 3 and 5 are designed so as to e expansively adjustable by a driver 18. Therefore, with these cables 3 and 5 adjusted, the overall length of a blade of the wiper 2 is adjusted. With this constitution, since a windshield an be wiped clean while expanding the wiper blade properly, raindrops sticking to the whole windshield of an automobile are sweepable away, thus any unwiped parts are eliminable.

Description

【発明の詳細な説明】 （Ａ）産業上の利用分野 この発明は、自動車の窓面に付着する雨滴を目的とする
窓全面に対し、ワイパーブレードを、伸縮させながら、
拭き払う装置に関するものです。DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Field of Application This invention is directed to a wiper blade that is extended and contracted to remove raindrops that adhere to the window surface of an automobile.
It's about a wiping device.

（Ｂ）従来の技術 これまでの自動車用ワイパーは、ワイパーブレードの長
さが、固定された状態で運動をすることにより、雨滴の
拭き払いをしておりまず。(B) Conventional Technology Conventional automobile wipers wipe away raindrops by moving the wiper blade while keeping it fixed in length.

（Ｃ）発明が解決しようとする問題点 現在のワイパーは、ワイパーブレードの長さが、固定さ
れているために、扇状の範囲を越える部分の拭き残りが
あり、このため視界不良の部分が生じる。(C) Problems to be solved by the invention In the current wiper, the length of the wiper blade is fixed, so there is a portion left unwiped beyond the fan-shaped area, resulting in areas with poor visibility. .

（Ｄ）問題点を解決するための手段 窓面の形状に対し、伸縮しながら、雨滴を拭き払う可動
ワイパーの腕と、ワイパーブレードを、伸縮させる駆動
装置。(D) Means for solving the problem A drive device that expands and contracts a movable wiper arm and a wiper blade to wipe away raindrops while expanding and contracting according to the shape of the window surface.

ワイパーブレードは可動腕に固定した部分と窓面に対し
、伸びる量に追随すべく、ブレード・ガイドに収容した
部分がある、このブレードの全長は可動腕が伸びきった
量を保有し、そこから先はワイヤーケーブルに接続し、
可動腕をコントロールするワイヤーケーブルと、一対に
して、駆動装置の偏芯コマへ取り付ける。The wiper blade has a part fixed to the movable arm and a part accommodated in the blade guide to follow the amount of extension relative to the window surface. Connect the tip to the wire cable,
Pair it with the wire cable that controls the movable arm and attach it to the eccentric piece of the drive device.

この偏芯コマは二枚を一組とし、窓面の形状に合わせた
偏芯の量をコマの巻着は面に加工する、偏芯コマの運動
は、ワイパーの駆動部から採り、偏芯コマに取り付けた
歯車を回す、偏芯コマは、歯車ラックの行きで二回転、
帰りで二回転をする、このことは、ワイパーが行きの時
に偏芯コマ（Ａ）？こ巻着いたワイヤ４−ケーブルを伸
ばし、偏芯コマ（Ｂ）に巻着けて縮める、ワイヤーケー
ブルは伸縮するブレードが窓面に対し、一番伸びた所を
０位置とし、二組の偏芯コマは、回転を支えるシャフト
に対し往復するようネジ加工を施し、回転に応じ、往復
しながらワイヤーケーブルの長さをコントロールする。These eccentric pieces are made into a set of two pieces, and the amount of eccentricity that matches the shape of the window surface is processed on the surface.The movement of the eccentric pieces is taken from the drive part of the wiper, and The eccentric top rotates the gear attached to the top, and the gear rack rotates twice,
Does this mean that the wiper rotates twice on the way back, or is the wiper eccentric when going back? Stretch the wrapped wire 4-cable, wrap it around the eccentric piece (B), and shrink it. The top is threaded so that it reciprocates on the shaft that supports rotation, and controls the length of the wire cable as it reciprocates according to the rotation.

尚、冬期の凍結が予想されるため、可動腕の部分に熱線
ヒーターを組み込みスムーズな可動ができるようにする
。In addition, since freezing is expected in the winter, hot wire heaters are installed in the movable arms to ensure smooth movement.

又、ワイパーの取り付は数は窓面の形状に応じ一本から
複数にし、取り付は位置に対しても−、この構成は応用
できる。Further, the number of wipers to be installed can be changed from one to a plurality according to the shape of the window surface, and this configuration can also be applied to the installation depending on the position.

（Ｅ）発明の効果 本発明の効果は、窓面に付着する雨滴にたいし、窓全面
を拭き払うことができ、降雨時の視界不良を改善し、安
全運転の確保になります。(E) Effects of the invention The effects of the invention are that raindrops that adhere to the window surface can be wiped off the entire surface of the window, improving poor visibility during rain and ensuring safe driving.
