Interlocking mechanism for a window or the like

Abstract

An interlocking mechanism for a window or the like consisting of two window parts, in particular a fixed frame (3) and a window wing (4) hingedly mounted on the fixed frame (3), the The fixed frame (3) and the window wing (4) each comprise a flange with side walls (5, 7) and joists (6, 8), characterized in that the interlocking mechanism (2) consists of at least one pin ( 14), the pin can move axially in the side wall (6) on the outer periphery of the window wing (4) or in the longitudinal guide (9) in the joist (8), and the pin can at least partly pass through The distal end of the side wall (6) or joist (8) in an extreme position extends.

Description

technical field [0001] The present invention relates to interlocks for windows or the like, in particular of the so-called anti-theft type. Background technique [0002] It is already known to equip casement and / or tilting windows with an interlocking mechanism consisting, on the one hand, of one or more slats movably arranged in guides on the periphery of the window wing, one of which or a plurality of cross-opposite protrusions are respectively provided on these slats; on the other hand, the interlocking mechanism consists of metal or plastic posts on the inner periphery of the fixed frame, wherein the metal or plastic posts are equipped with safety hooks for By locking the window wing relative to the fixed frame, the above-mentioned protrusion can be retained on the safety hook. [0003] A disadvantage of this known interlocking mechanism is that the aforementioned protrusions can only have a limited length, since to be able to open and close the window, these protrusion...

Problems solved by technology

[0003] A disadvantage of this known interlocking mechanism is that the aforementioned protrusions can only have a limited length, since to be able to open and close the window, these protrusions must fit between the window wing and the window fixing part

[0004] However, this limited length of the protrusions is disadvantageous because they can only engage behind the edge of the fastening hook for a limited length, so that with relatively little effort they can be pushed out of the fastening hook at an oblique angle to the window, thus for For example, burglars, it is relatively easy to open the windows

[0005] Another disadvantage is that the aforementioned protrusions cannot simply be placed at the corner points of the window wing so that, when opening the window with a crowbar, a relatively large leverage is obtained, for example, between the closing side of the window and the aforementioned protrusions, thus, windows are easily pushed open
