DE1069493B - Catch for the sash, in particular for the lifting sash of doors, windows or the like - Google Patents

Description

The invention relates to a catch for the sashes, in particular lifting sashes, of doors and windows od. The like., With a snap roller or snap ball, which in a locking opening in a direction of movement the catch roller or ball extending strike plate engages.

There are catches of this type are known in which the locking device is formed by a strike plate which is fastened flat on the face of the fixed frame and with pushed out protrusions is provided.

The part forming the locking device is proportionate awkwardly designed and stands over the surface of the sash frame receiving the latching device forward, with the locking roller sliding over the projection with a resilient push back, before it reaches the locking position limited by the projection in the opening direction.

In contrast, the invention aims above all to provide a particularly simple, inconspicuous attachment Locking device in which the catch roller or ball is held particularly securely in the locking position, and consists in that a partially cut out of the strike plate to form the latching opening Tabs of the strike plate Z-shaped out of the plane of the same and parallel to this at such a distance is bent from the plane of the locking plate that he as a depth of engagement of the catch roller or -ball-determining stop is used for this.

In contrast to the known design, the catch roller or ball undercuts the plane of the strike plate, the bend directly limiting the detent depth behind the plane of the strike plate. It is thereby achieved in the simplest way that the entering into the locking opening of the strike plate Roll is actually only at such a depth in the locking opening that jamming the role in the opening is excluded.

Preferably, the locking edge over which the catch roller or the like is raised when the sash is opened must be, through a sharp edge, especially the cut edge of the not bent Sheet metal part, formed. In this way, a particularly firm engagement can be achieved even without a larger engagement depth. +5

Fixed frame referred to, the wing is assumed to be a lifting sash.

The catch device is inserted into the casement. This includes one screwed into the casement Base plate 12 to which a support bracket 13 is riveted or screwed. In a Opening of the base plate 12, the catch roller 15 is used, which by means of pin 16 with a vertical Axis is mounted in a frame fork 17. This is axially guided on a screw bolt 18, which in turn is screwed into a guide bushing or sleeve 19. One against the storage fork 17 on the one hand, and the support bracket 13 on the other hand, the spring 24 supporting the bearing bracket 17 also seeks here to press the roller 15 outwards until the collar of the sleeve 19 rests on the bracket 13.

The catch roller 15 works together with a locking plate 27 which is screwed to the frame 11 by means of screws 31 and has a locking opening 32 corresponding to the stroke of the sash. The locking opening is formed in that a tab 33 is cut out of the locking plate 27 on three sides and bent by an amount t corresponding to the desired locking depth of the roller 15, and on the one hand by the rounded portion 34 of the bent tab 33 and on the other hand by the sharp edge 35 of the not bent part of the flap is limited.

When the sash is open - as already mentioned - ■ the roller 15 with the bearing bracket 17 pressed by the spring 24 outward, so that the collar of the sleeve 19 on Bracket 13 is applied. If the wing is closed, the roller 15 is at the outer rounded edge 36 of the Locking plate 27 is printed inwards and then snaps into place

the opening 32 under the action of the spring 24. The sharp edge 35 also ensures that it snaps firmly into place, so that the wing is prevented from opening under the action of a draft of air or other smaller forces. On the other hand, however, the engagement depth is limited to such a value that disengagement under a normal, more or less strong opening pressure P is ensured under all circumstances, in that the roller 15 is pushed back by the wedge action on the edge 35 against the action of the spring 24 and thereby over the edge 35 is lifted out of the latching opening 32. The engagement depth t is also independent of any loosening of the screw 18. Patent claims 1. Catch for the sash, in particular lifting sash, of doors, windows or the like. With a Snap roller or snap ball, which in a locking opening in one direction of movement the catch roller or ball extending strike plate engages, characterized in that a tab of the partially cut out of the strike plate to form the locking opening Striking plate Z-shaped from the same plane and parallel to it at such a distance is bent from the plane of the locking plate that it is used as a depth of engagement of the catch roller or -ball-determining stop for this is used. 2. catch according to claim 1, characterized in that that the locking edge over which the catch roller od. Like. When opening the wing must be raised by a sharp edge, especially the cut edge of the not bent Sheet metal part is formed. Considered publications:
