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the socket, thereby rotationally coupling the handle and the socket, but will not allow the polygonal driver to be withdrawn in the opposite direction.

Actuating handle

A detent assembly&#x2014;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&#x2014;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. The stop is fitted with guides containing compression springs to prestress balls and to guide them at an angle to the line of symmetry of the notches. To attain play-free interlocking, the guide-supported detent balls act point-wise on the interlocking notches of the disk.

Detent assembly and its application to actuation means

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.

Operating mechanism

Latch and lockset system

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.
