  • Patent number: 5102174
    Abstract: A gearing for use in a fitting for a door leaf or window leaf having a frame profile including a guide groove on the movable frame open in the direction of the rabbet space between the movable and stationary frames of the door or window. The positioning rod gearing comprises a partially insertable gearing housing (7) and a guide section (7c). A connecting slide (19) is supported in a longitudinally shiftable manner in the housing guide part (7c) which slide comprises a coupling extension (21) on at least one end for coupling a positioning rod (22). A drive pinion (13) which is rotatably supported in the housing (7) can be rotated by means of an operating handle of the positioning rod gearing and meshes with a cogging (17) of the connecting slide (19).

  • Patent number: 5095583
    Abstract: Folding-arm bearing for an oscillating-swinging leaf of doors, windows or the like, comprises a support inserted on the sash-frame and a square-shaped blade having a wing onto which is pivotally mounted a plate bearing a folding-arm leg by a connector. In order to facilitate the reversibility of this folding-arm bearing without disassembling of components, the wing of the blade is provided, on its upper and lower edges, with a pin engaging into an opening made in the connector, and the plate is mounted onto this wing by means of an eccentric having a rotation which generates a vertical movement of the plate causing the disengagement of a pin from the opening present in the connector.

  • Patent number: 4989428
    Abstract: A locking device such as a lock, espagnolette, espagnolette-lock and the like comprises a headpiece having an inner face onto which is inserted at least one casing comprising two parallel walls. The assembling between the headpiece and the casing or casings is obtained by means of riders in the form of profile lengths with a "U"-shaped cross-section comprised of two parallel wings and a transversal wall made integral with the inner face of said headpiece, both parallel wings of the riders forming means for seizing each of the parallel walls of the casing or casings.

  • Patent number: 4964660
    Abstract: A device for improving the safety and air tightness of doors, casement windows, or the like and is applicable to casement locks, casement bolts, multi-bolt locks, or the like. The device comprises in combination a dead bolt and a mechanism for positioning and urging the leaf of the door, window or the like against its dormant frame. The positioning mechanism and the dead bolt are actuated sequentially by a control member such as a control rod cooperating with the control mechanism of the casement bolt, casement lock, multi-bolt lock or the like.

  • Patent number: 4902056
    Abstract: A locking fitting for the sliding leaf of a window, door, or similar type closure which includes, in its housing, a slide connected to a bolt with a hook. The hook cooperates with a keeper which is fixed against movement with the fixed frame. After the movable closure is opened, the hooked bolt is maintained in its unlocked position by a blocking device having an elastic return. Further, the blocking device is formed by an assembly separate from the slide and includes a support which is clamped in the U-section of the movable closure. The support is fitted with a blocking lever which cooperates with the keeper when the movable closure is closed so as to free the hooked bolt for movement and, in consequence, the slide.

  • Patent number: 4896866
    Abstract: The double-acting shock absorber producing the throttling of a fluid flowing through a constricted passage for damping out a movement in constructed, in combination of, a fixed piston (2) and a fixed cylinder (3) cooperating both with a movable member (4). This movable member has two axially aligned portions, that is, an upper portion (5) and a lower portion (6), the upper portion having a cylindrical cavity in which the fixed piston (2) is slidably fitted, and the lower portion having the configuration of a piston slidably engaged in the fixed cylinder.

  • Patent number: 4864692
    Abstract: A hinge for doors or windows which includes a first blade fitted to a door or window and a second blade attached firmly to the casing of the door or window. One of these blades is provided with a central knuckle placed in the free space between two end knuckles attached firmly to the other blade, and one pin engaged in these knuckles ensures the free rotation of one blade as compared to the other. The aforesaid central knuckle comprises, furthermore, a pore that opens into one or more housings into which are engaged plugs provided with jaws fitted with catches that enter into peripheral grooves made in the pin. These jaws take the shape of a cylinder with an outer diameter equal to the inner diameter of the boring of the housings, less twice, at least, the thickness of the catches.

  • Patent number: 4836588
    Abstract: This automatic double-action casement bolt comprises a pair of locking bars urged by resilient return means to a locking or bolting position in which the bars engage corresponding keepers, these bars being retracted from the keepers and moved to their unbolting position by a set of angular levers fulcrumed at their vertices on the casement bolt casing, each angular lever being connected through one arm to one of the sliding bars, each angular lever comprising, at the end of its other arm, a notch engageable by a catch of at least one control rod movable in a direction across the bars and formed integrally with an operating and control handle urged by other resilient means to its inoperative position, the notch of the other arm of each angular lever being formed in the edge of this arm so as to provide an open clearance of which the bottom constitutes a striking edge adapted, when the casement bolt is unbolted, to co-operate with the catch of the control rod.
