Fittings for at least liftable but preferably also movable leaves of windows or doors

Abstract

The invention relates to an accessory for an at least liftable but preferably also movable leaf of a window or door, which accessory includes a slide rail (16), wherein a vertical mounting is provided inside an accessory groove (20) of the leaf (2). The straight wing beam (23) is provided with a control lever (7), which has a connecting rod (8), which can move downward with the help of the operating mechanism (5) to make the wing leaf (2) is lowered and this movement is transmitted via the angle reversing part (9) to at least one coupled carriage (10), wherein the fitting has a locking device (21) which is fastened by means of the housing (26) The control lever (7) can be coupled to the control lever (7) inside the accessory recess (20) and via a guide (24), wherein the guide (24) can be used to actuate the control lever (7). The connecting rod (8) moves and is controlled by the driver guide (27) on the guide (24) and passes the pivot point (28) on the housing (26) of the locking device (21) The rotatably mounted pivot lock (29) is transferred from the open position covered in the housing (26) inside the operating lever (7) opposite to the direction for lowering the leaf (2) into the locked position. in the free actuating area (30) of the position, wherein the pivot lock (29) has a first link (31) which is form-fittingly engaged when transitioning into the blocking position. The pin (32) fixed to the frame (1) and provided for the locking engagement piece (22) engages, and wherein the pivot lock (29) has a second slide groove (33), which The second slide groove extends almost parallel to the first slide groove (31) and is set by the end (34) far away from the rotation point (28). It engages with the pin (32) to form a gap opening position.

Description

technical field [0001] The invention relates to a fitting for at least a liftable, but preferably also movable, leaf of a window or door. In this context, the invention relates in particular to a locking device with an actuating lever arranged on the leaf, said actuating lever having a linkage, which is displaceable downwards by means of an actuating handle in order to lower the leaf. Background technique [0002] This lowering, due to the own weight of the leaf, thus brings about a hermetic locking of the leaf relative to the frame. [0003] Usually liftable wings are additionally adjusted, in particular moved sideways, after lifting. Thus, eg in the case of a door, the leaves release the access opening. In the closed position, the leaf must be as tight as possible relative to the fixed frame. For this purpose, the leaves are equipped with sealing strips or the like, which bear against corresponding counter-sealing surfaces of the fastening frame when the leaves are lowe...

AI Technical Summary

Problems solved by technology

[0008] Since the known fittings only concern sliding and non-lifting flaps with subsequent movement of the window or door, an automatic lowering device is not realized

Furthermore, the locking device proves to be complex and thus also cost-intensive in production

Furthermore, the locking element is prominently visible on the leaf in the open state, which has a visually disadvantageous effect and creates a possible risk of damage when passing through the opening of the door or also during cleaning.

[0009] No additional gap ventilation is produced by the known device
