DESCENDING WINDOW OPENING AND CLOSING AUXILIARY TOOL
To provide a descending window opening and closing auxiliary tool capable of designing a thickness to be compact and improving durability.SOLUTION: A descending window opening and closing auxiliary tool 1 includes: a body 2 arranged below a descending window; and an arm 4 capable of revolving vertically with a roller 4a on its tip. The body 2 includes a link unit 6, a spring unit 8, and a support unit 12 inside. The link unit 6 is composed in a both-lever mechanism with a part of the body 2 as a fixed joint. The arm 4 is attached to a prime mover joint 6a of the both-lever mechanism to be capable of revolving integrally. The spring unit 8 has coupling metal fittings 8b, 8c coupled to both ends of coil springs 8a arranged in parallel. The coupling metal fitting 8b on one end of the spring unit 8 is coupled to a coupling point 6cc on a follower joint 6c of the both-lever mechanism and a coupling joint 8c on the other end is supported by the support unit 12 through a spring fixing pin 10. A virtual straight line which is in parallel with a stretching direction of the spring unit 8 and passing through the coupling point 6 cc is configured to always pass through in between the joints on both ends of the follower joint 6c.SELECTED DRAWING: Figure 1
【課題】厚さをコンパクトに設計できると共に、耐久性の向上が可能な下降窓開閉補助具を提供する。【解決手段】下降窓開閉補助具１は、下降窓の下方に配置される本体２と上下に旋回可能であり先端にローラ４ａを有するアーム４を備えている。本体２は、内側にリンク部６、バネ部８及び支持部１２を備える。リンク部６は、本体２の一部を固定節とする両てこ機構で構成されている。両てこ機構の原動節６ａにはアーム４が一体回動可能に取り付けられている。バネ部８は並列に配置されたコイルバネ８ａの両端に連結金具８ｂ、８ｃが連結されている。バネ部８の一端の連結金具８ｂが、両てこ機構の従動節６ｃ上の連結点６ｃｃに連結され、他端の連結金具８ｃは、バネ固定ピン１０を介して支持部１２に支持される。バネ部８の伸縮方向に平行であって、連結点６ｃｃを通る仮想直線は、常に、従動節６ｃの両端のジョイントの間を通るように構成される。【選択図】図１
