Abstract:
Die vorliegende Erfindung betrifft einen Türschließer mit einem Gehäuse (1) und einem in dem Gehäuse (1) angeordneten Regulierventil (2), wobei das Regulierventil (2) einen hohlzylindrischen Fortsatz (4) aufweist, der mit zumindest einer die Wandung des Fortsatzes (4) radial durchsetzenden Ausnehmung (6) versehen ist, und wobei die Außenseite (9) der Wandung des Fortsatzes (4) im Gehäuse (1) des Türschließers fluiddicht geführt ist.
Abstract:
A glass door hinge having an internal door stop arrangement comprises: a housing; a mount for coupling the housing to a support member; a pair of clamps; an axial spindle; and a plurality of biasing members arranged to engage the spindle to return the clamps to one of a plurality of positions selected from a closed position and one or more opened positions; wherein the spindle has a plurality of centering surfaces; each biasing member being arranged to apply a force to a respective centering surface to centre the clamps in one or more of said positions.
Abstract:
The invention relates to a component (201), in particular a window or door with a pivoted leaf, a top-hung window, pivoted window or sash window, comprising a frame (103, 203) and a leaf (102, 204) which may be pivoted about an essentially horizontal pivot axis (209) or moved in a sliding manner relative to the frame (103, 203), a closing device (1, 101, 217) for the delayed or retarded independent closing of the leaf (102, 204) and a locking system (169, 239) for locking the leaf (102, 204) in the closed position on the frame (103, 203). On closing the leaf (102, 204) the locking system has an independent self-locking design and comprises a locking element (170, 240) with a locking surface (174, 249) which may be fixed to the frame (103, 203) and a locking device (171, 241) which may be fixed to the leaf (102, 204) with a locking body (176, 248) cooperating with the locking surface (174, 249).
Abstract:
A door closer for mounting between a door leaf and a door frame, the door closer comprising: an elongate housing for mounting in one of the door leaf or door frame, a plunger disposed in and movable along the housing, a biasing element disposed in the housing and biasing the plunger inwardly of the housing, and a rigid tension member having a first end pivotally connected at a first pivot to the plunger and a second end, and an anchor element assembly to which the second end is pivotally connected at a second pivot, the first and second pivots having parallel pivot axes, the anchor element assembly comprising a mounting member, for mounting in the other of the door leaf or door frame, and a link member extending from the mounting member, the second pivot being located at a free end of the link member remote from the mounting member, wherein the rigid tension member comprises a central portion between the first and second ends thereof, at least a part of the central portion having a reduced thickness in a direction orthogonal to the axes of the first and second pivots.

Abstract:
In order to simplify the manufacture of the housing of an automatic door-closer with hydraulic shock absorber, the housing is designed as a tubular hollow cylinder (105) with an external overflow channel (121) with one or more tightly fitting covering elements (102).
Abstract:
A door closer capable of securing a large door closing force in a wide range up to a fully closed position or a position immediately before the fully closed position without increasing a load thereon for opening a door. In closing the door, the elastic deformations of springs (8) and (9) produced by a door opening operation are partly maintained in a deformed state until the door is fully closed or immediately before the door is fully closed, and then the deformed state is released to reset the springs (8) and (9) to an initial state before the door opening operation. A boosting piston (10) is moved when the door is opened to elastically deform the springs (8) and (9) in association with a piston (7) so as to maintain and release, as a part of the elastic deformations, the elastically deformed parts of the springs (8) and (9) due to the movement of the boosting piston (10) in s deformed state until the door is fully closed or immediately before the door is fully closed when the door is closed.
