Abstract: A window or door fitting for actuation of a mechanism integrated in a window or a door has a stop body that can be attached to the window or the door, a handle, that is rotatably mounted on the stop body in an axially fixed manner, a polygonal element for the mechanical coupling of the fitting to the mechanism integrated in the window of the door, and a coupling configuration formed between the handle and the polygonal element, with which a torque transference from the handle to the polygonal element can be effected, but can be blocked in the direction from the polygonal element to the handle. The coupling configuration has two driving elements for this, wherein a first diving element is connected to the handle in a rotationally locked manner, while a second driving element accommodates the polygon in a rotationally fixed manner.

Abstract: The invention relates to a lock assembly (10) of a planar component (22) displaceably mounted in frame (30). Said assembly (10) comprises an engaging element (40) which, in said planar component's closed position, can be fixed in place in a latching system (50). Said latching system is designed in a manner that, in its blocked position, the engaging element, for instance a bar affixable by compression and/or friction in the latching system (50), can be inserted into latter in a first direction (R) opposite the direction of closing (X) of the planar component (20), whereas such insertion is blocked in a second direction (S) which is opposite said planar component's direction of opening (O). This design allows almost noiselessly operating the lock assembly. The planar component also may be closed when the latching system is in the blocked position already when the planar component is open.

Abstract: An actuating handle for a window or door including a fixing element coupled to a socket, the socket being selectively rotatable relative to a stop plate. The fixing element will allow insertion of a polygonal driver coupled to a handle from one direction through the socket, thereby rotationally coupling the handle and the socket, but will not allow the polygonal driver to be withdrawn in the opposite direction.

Abstract: A detent assembly—namely of pairs of sub-assemblies of which the individual ones comprise spatially directly associated surfaces at which projecting elements cooperate with engaging elements in prestressed manner—comprises at least one detent element within a detent sub-assembly, said detent element being retained prestressed within an obliquely directed guide in a manner that it projects beyond a detent sub-assembly outer surface and that it enters an aperture sub-assembly while being obliquely prestressed into a recess of an opposite aperture outer surface and rests only unilaterally and point-wise against associated rim sites of the mutually associated interlocking zones. A preferred application relates to a handle being supported rotatably but in axially fixed position by a stop fitted with a disk connected to a handle extension and comprising circumferential interlocking recesses, for instance notches.

Abstract: An operating mechanism for building components such as windows, doors and the like comprises at least one handle and an actuating element that ca be made to engage the handle in a mutually non-rotational manner. A blocking device is situated between the handle and the actuating element and is designed so that the actuating element is insertable in a first direction into the handle whereas its displacement in the opposite direction is blocked.

Abstract: An operating device for doors, windows, etc. comprises a rosette (20) for holding a rotating handle (10) whose head (12) contains a lock cylinder (18) with an axially displaceable locking bolt (44) that is axially spring-loaded and automatically assumes an engaging position at a defined angle of rotation of the handle (10) by sliding over a stepped locking sleeve (30) of the rosette (20). The lock cylinder (18) has a core (40) with a radial opening (50) in a non-rotating wall (58) for controlled movement of a spindle (48) that radially extends from the locking bolt (44) which engages the locking sleeve in defined angular positions of the handle (10). The opening (50) extends over a peripheral angle of e.g. 180° to 220°, and is a contoured window having a lower flat segment (52), a depression (54) and a steeper segment (flank 56).

Abstract: A handle (10) supported pivotably but axially tight on an installation body (20) has a polygonal bar (30) mounted for rotation within a handle neck (12) for actuating a closing mechanism. Two drivers (15, 35) movable relative to each other are engageable in a non-positive and/or a positive way between neighboring surfaces (17, 37) either directly or by means of coupling elements (36, 40, 42) so that a torque transmission from the handle (10) to the polygonal bar (30) is free but is blocked from the polygonal bar (30) to the handle (10) as at least one coupling element (36) is displaced in the direction of the attack. A main portion of a polygonal driver (35) may be concentrically enclosed by a two-shell handle driver (15) having wings (52) with front faces (19) which drive e.g. pairs of spring-loaded roller pins (36) held in a wedge-shaped confining zone (55). Corner areas of indentations (31) of the polygonal driver (35) serve to attack the roller pins (36).

Abstract: For mounting the hollow ends (H) of a curved handle (G) in an orifice (B) on a contact face (A), a guide member (30) for a screw (29) has a base flange (31) which can be connected to expanding parts (39, 40, 60, 64) or a securing member (47) and on which there rests a tubular supporting member (12) which overlaps the hollow end (H). A cap nut (20) having a peripheral groove (24) for fixing the hollow end (H) through a setscrew V and wrench faces (33 and 23) like the head (32) can be screwed on to a head (32) of the guide member (30). A shank (37) of the guide member (30) with a conical end (39) or conical nut (64) directed against it can be pulled into an expanding nut (40) or an expanding tube (60) by means of the screw (29), enlarging an expanding basket (42, 62). A door handle (50) can be fixed, for example, on a multi-chamber profile (M), with the securing of a polygonal pin (47), the guide member (30) being secured externally by a flange ring (55).

Abstract: A multi-point locking system (10) has a lock case (11) with a door front edge (20), a latch (65), a blocking bolt (80) and two longitudinally movable push rods (30, 31) connected to one another by a connecting element (40) with locking elements such as eccentrically mounted roller pins (33) engaging in striking plates (34). The connecting element (40) has an engagement recess (46), is arrestable by a spring-loaded engaging element (52) against a compression spring (48) in a pretensioned opening position, and is releasable from this arrested position by direct operation of the locking elements (33) in the longitudinal direction of the door front edge. The striking plates (34) in the entry area (36) of the locking elements (33) have inclined stop surfaces (37) exerting a force (F) on the roller pins (33) in the closing direction (Y). The slidingly guided bolt (80) blocks the locking system (10) indirectly via a flexibly mounted rocker (91) using a closing element (81), for example a locking cylinder.

Abstract: A drive type operating mechanism for locking gates, windows, double-wing doors and the like includes push rods which are movable longitudinally in opposite directions to effect locking of the upper and lower ends of the door with the surrounding framework. The mechanism is connected for actuation by a lever handle through an arrangement of follower elements that are slidable supported in a lock case. A nut sleeve follower which is rotatable by the lever handle has one claw which cooperates with a groove in one longitudinally movable follower, and a second claw which cooperates with a transversely slidable intermediate follower which in turn cooperates with a groove in the second longitudinal follower, this arrangement ensuring that upon rotation of the handle the followers (and hence the locking bolts) move in opposite directions. A lock mechanism ensures that the longitudinally movable followers are not inadvertently moved from their end limiting positions.
