Abstract

一种窗叶自动扣,它主要由扣座和扣片组成,扣 座上有一L形弹片,可由弹簧钢制成。扣座和扣片 分别用木螺钉固定在窗框和窗叶上,当需关闭窗叶 时,只需将其向内拉拢,L形弹片被扣片压下后再自 动弹回即扣合。本窗叶自动扣设计精巧、结构简单、 制作极易、成本低廉、安装和使用均极为方便,特别是 忘记挂上风钩而遇大风时,能实现窗叶自动关闭,达 到保护窗叶和玻璃的目的。原料可选用边角余料,更 能降低成本、废物利用。

Description

本实用新型是一种固定窗叶的紧扣装置,特别涉及到一种自动窗扣。
目前,人们一般采用插销结构来固定窗叶,关窗时一手拉窗叶,一手按插销。由于有时或因插销弯损和插销与插孔错位,或因未上风钩导致窗叶敞开时,一遇大风极易使玻璃受损。
本实用新型的目的在于提供一种结构简单、制造容易、使用方便、成本低廉,遇到大风时能使未上风钩的窗叶自动关闭的窗叶自动扣。
本实用新型的技术方案:参看附图来说明,从图二可以看出,窗叶自动扣是由扣座(1)和扣片(2)两部分组成,其中扣座(1)是由L形弹片与底板构成一个整体,即底板上的L形弹片是由座板一侧延伸部分经三次褶压成L形弹片,弹片末端包扣底板的另一侧,以防L形弹片受损,松驰时,L形弹片与底板夹角为10°~20°。扣座(1)和扣片(2)上都有上木螺钉的安装孔。安装由外向内关的窗叶(图一)时,扣座装于窗框下边的横木上(单页窗可装在竖木上),扣座下的横木上备有一槽,以不阻挡L形弹片向下弹动;扣片装于窗叶上,扣片下也开有弧形木槽,供开窗伸手指用。关窗时,将窗叶向内拉拢,扣片(2)与扣座(1)相接触。迫使扣座上的L形弹片向下弹动,当扣片(2)通过后,L形弹片回弹复位,扣片与扣座相扣合,实现其自动关闭扣紧窗叶的目的。如遇大风,未上风钩的窗叶可借风力自行关窗,达到保护窗户与玻璃之目的。开窗时,只需将手指从弧形木槽处伸进压下弹片外推即成。安装由内向外关的窗叶时,扣座装于窗叶上而扣片装于窗框上亦成。扣片(2)用钢片制作,扣座(1)用弹簧钢片制成。
综上所述,本实用新型具有结构简单、制造容易、成本低廉,安装和使用均很方便的特点。特别是在遇大风时,未上好风钩的窗叶可随风自行关窗,可防窗户和玻璃受损。同时,它可用金属边角废料作原料,可降低成本、节省用材。
