Fittings for liftable and/or movable leaves of windows or doors

Abstract

Accessory for an at least liftable and / or tiltable, but preferably also movable, leaf (2) of a window or door, which accessory has a slide rail (16), wherein the accessory of the leaf (2) Inside the slot (20) there is a control lever (7) on the vertical sash (23), which control lever has a transmission rod (8) that can be moved downwards by means of the operating mechanism (5) in order to The leaf (2) is lowered and this movement is transmitted via an angular transmission element (9) to at least one coupled carriage (10), the fitting having a locking device (21) which is secured by means of a housing ( 26) is fixed on the joystick (7) inside the accessory groove (20) and can be coupled to the joystick (7) via a guide (24), wherein the guide (24) can be used to operate the joystick (7) The drive rod (8) moves and the pivot lock (29) is moved from the covered open position inside the operating lever (7) in the housing (26) against the position for lowering the leaf (2). The direction is transferred into the free actuating area (30) of the blocking position, which pivot lock is controlled on the guide (24) by a follower guide (27) and is rotatably mounted on the guide (24) via a pivot point (28). on the housing (26) of the locking device (21), wherein the free end (46) of the pivot lock (29) upon transition into the locking position engages the The pin (32) assigned to the locking insert (22) engages rearwardly, wherein the locking insert (22) has a locking plate (32) which is arranged almost flush with the surface of the door and window frame (1). 62), the locking plate has a cutout (63) for passing the pivot lock (29), and the locking engagement utilizes the free end (63) of the pivot lock (29) 46) engages in the free space (64) between the pin (32) and the locking plate (62) to form the gap open position.

Description

technical field [0001] The invention relates to a fitting of at least a liftable and / or tiltable, 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, which has a transmission rod which can be moved downwards by means of the operating 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] As a rule, liftable wings are additionally adjusted, in particular moved sideways, after lifting. Thus, the flap releases the passage opening, for example in the case of a door. 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 fixed frame when the leav...
