Stopper suitable for being installed on top rail of aluminum door and window

Abstract

The invention relates to a stopper which is suitable for being installed on a top rail of aluminum door and window and mainly applied on horizontal-pulled aluminum door and window. The stopper is arranged on an inner window groove rail of a window frame top rail of the aluminum door and window; a detent bolt which is movably telescopic in an accommodating groove of a stopper seat body is utilized, and the detent bolt is arranged in a penetrating hole prearranged by an outer window sash frame body in a penetrating way when extending outwards and blocked to further enable the seat body to form a stop block piece so as to limit an opening gap when an inner window sash is opened; when a window sash is to be unfreezed to recover the completely-opened function, the detent bolt on the seat body only needs to shrink inwards so as to keep out of the blocking of the penetrating hole of the outer window sash frame body.

Description

technical field [0001] The present invention relates to a stopper suitable for installation of upper cross members of aluminum doors and windows. By protruding or retracting the stop bolts on the stopper, the openable positions of the window sashes on both sides are restricted, and it is especially suitable for use in horizontal Pull-type aluminum doors and windows or similar structures. Background technique [0002] By the way, due to the restrictions of the appearance maintenance convention and the consideration of escape and disaster relief in many buildings nowadays, it is impossible to install iron window fences outside the windows of the buildings. Therefore, the safety protection function of aluminum doors and windows has been paid more and more attention. Structural design, because of its architectural planning and use requirements, can be roughly divided into two types: push-out type and horizontal pull-type. Among them, as far as the horizontal-pull aluminum doors ...

Problems solved by technology

[0005] Although the above-mentioned limiter or safety lock can prevent the window sash from fully opening when in use and achieve the effect of child safety protection, but because they are all installed on the inside of the outer window sash, they only have the function of stopping the lateral movement of the window sash. As far as people are concerned, it is still possible to disassemble the window sash only by lifting the outer window sash upwards, so these devices are still insufficient for home security and anti-theft functions.

Furthermore, since these devices all need to be driven by a key to drive the lock unit when in use, and if multi-stage opening spacing adjustments are required, multiple stop members need to be added, so it is difficult to use and install. It is quite inconvenient, and the cost of manufacturing and use is also relatively high, which is still not ideal. Therefore, how to solve the above-mentioned problems and shortcomings is the goal of the relevant industry to strive for breakthroughs in research and development
