Abstract

五折伞骨架省力装置,涉及一种折叠伞的支撑装置。其技术方案为:用活动套环将组成第三折骨架的平行四边形的一边栓套在与其对应的另一边上。本实用新型具有结构简单,开合轻松方便的优点。

Description

五折伞骨架省力装置
本实用新型涉及一种折叠伞的支撑装置。
折叠伞因其小巧灵便,日益受到人们的喜爱。然而,当伞在撑开的过程中,要使用较大的力气,才能将撑开伞面的骨架撑开,这对年老体弱者来说,的确是一件憾事。
本实用新型的目的在于提供一种五折伞骨架省力装置。
本实用新型是通过如下技术方案实现的:在四折杆的端部及二折杆上连接有金属丝,并与铆接在二、四折杆上的三折杆构成平行四边形的两条边,金属丝穿过套环,套环亦套住固定金属丝,固定金属丝的两端固定在三折杆上。
本实用新型具有结构简单,开合轻松灵便的优点。
下面结合附图对本实用新型进一步说明:
附图1为本实用新型结构图
附图2为三折杆3的纵向剖视图
见附图1、2,本实用新型包括一折杆1、二折杆2、三折杆3、四折杆4(五折杆在图中未标),各折杆分别依序铆接,在四折杆4的端部及二折杆2上连接有金属丝31,并与铆接在二、四折杆2、4上的三折杆3构成平行四边形的两条边,金属丝31穿过套环32,套环32亦套住固定金属丝33,固定金属丝33的两端固定在三折杆3上。
使用本实用新型时,用手推动伞杆上的下巢体5,使得一折杆1推动二折杆2向外运动,同时二折杆2推动三折杆3运动,与三折杆3构成平行四边形对应的另一条边为金属丝31,当未推动时,两条边重合;推动发生时;因金属丝31穿套在套环32内,且套环32亦套住固定金属丝33,故金属丝31只能在套环32上滑动,同时也拉扯着金属丝31贴靠在三折杆3上,并且套环32也同时在固定金属丝33上滑动,在推动过程中,平行四边形的两条边之一的金属丝31短于另一边的长度,于是,金属丝31的一端猛拉四折杆4的端部,直至两条边又重合为止,同时套环32在固定金属丝33上滑动,起到了事半功倍的效果,当伞收拢时,亦是同样的道理。
