There is provided a hinge arm damper mechanism that reliably achieves a damper effect corresponding to a braking force of an elastic member. The hinge arm damper mechanism is configured to include a pinion gear, a pair of racks and, two sets of heavy load springs and, a pair of slide bars and, and a housing. The housing includes a box-shaped case and a plate-shaped cover. The case accommodates the pinion gear, the pair of racks and, the two sets of heavy load springs and, and the pair of slide bars and. A rotational torque applied to a hinge arm is transmitted to the racks and via a rotational motion of the pinion gear, and is converted into a linear motion of the racks and. The linear motion of the racks and is reliably braked by the respective springs and.

A device for opening and closing a pivoting wing, comprising: a stationary support intended to be attached to a fixed frame, a slide movable relative to the stationary support along a rectilinear direction between an open wing position and a closed and locked wing position, a pivoting arm articulated to the stationary support about an articulation axis, and having a distal end intended to be connected to the wing, a transmission mechanism associated with the slide and the arm, comprising an essentially L-shaped cam engaged by a control pin, the transmission mechanism being configured to transform the rectilinear movement of the slide along said rectilinear direction into a pivoting movement of the arm about said pivot axis.

A door system designed for buildings that store large objects such as airplanes or farm, marine, and other heavy equipment. The door system is comprised of a door, a lift frame, and a brake system disposed within the lift frame and coupled with the door. Furthermore, an articulating arm system connects to the lift frame and the door and a drive system connects to the brake system. The drive system moves the brake system within the lift frame such that the brake system and the articulating arm system guide the door between an open and a closed position.

A projection window operator providing horizontal displacement of a window relative to a vertical plane of the frame of the window. With at least one projection window operator installed on each of opposing sides of a window, the window can be actuated between a first closed position and second open position in which trickle ventilation is provided around the window. The projection window operators installed on a window can be interconnected for simultaneous actuation, or actuated individually, providing selective ventilation on either side.

A window including a window frame and a casement, the latter being mounted in the frame with the aid of a link-arm mechanism. The casement is pivotable from a closed position within the frame, through 180.degree. to a closed, fully reversed position in the frame. From the latter position, it is pivotable further in the same direction or reversely in the opposite direction.

A window stay assembly for fitment between a window frame member and a window sash member and having two preferably elongate window stays extending directly or indirectly between the window frame member and the window sash member. Those ends pivotably mounted preferably through a mounting plate to preferably the window frame member directly or indirectly interengaged by direct or indirect gearing so that the movement of one gives rise to some predetermined proportional or identical movement of the other. The distal ends of the window stays are themselves pivotably mounted directly or indirectly to the window sash member with at least on of the pivotal mounts being through a friction slide mechanism. The arrangement enables a reproducible opening of a window from its frame using a thin window stay assembly.

A stay generally indicated at 10 comprises a base 11, a window support 12 and a link 13. The link 13 is releasably and pivotally connected at 20 to the base 11. The connection at 20 is formed between a projection 22 and an end cap 23, which defines a through passage 25 for receiving the projection 22. The end cap 23 has an annular projection 26 which is dimensioned to snap fit into a circular groove 27 in the projection 22.

Hinge for a door, window or the like, the sash of which is partially overlapping the sash-frame and outwardly tiltable about a horizontal spindle located at the height of its upper rail including a) hinged lower compass arms imparting to the sash, at the very beginning of its opening, a path with vertical components, b) and upper hinge elements capable of simultaneously outwardly projecting the upper rail of the sash during the substantially vertical movement thereof. The hinge includes an assistance mechanism to push back, vertically and upwards, the sash at the end of closing, and to simultaneously position and center the sash with respect to the sash-frame.

A casement hinge is provided having a track mounted to a window frame, a sash arm mounted to a window sash and connected to a track pivot at one end, and a support arm pivotally connected to the sash arm at one end and having a track pivot at the other end. A block with a serrated surface defines one of the track pivots, and a rack secured to the track includes cooperating serrated surfaces for fixing the block to a selected position on the track. The rack and the block include cooperating surfaces allowing sag correction by wedging a tool between the cooperating surfaces. A tab and slot interconnection for centering the block relative to the rack during installation is provided where the tab is breakable from the member to which it is fixed when correcting sag. The track is formed with a longitudinal section mounted to the window frame, the longitudinal section having a guide portion on which a shoe slides and a mounting portion spaced from the window frame so as to be offset from the guide portion. The track further includes an upright section along one side of the longitudinal section and extending away from the window frame, an overhanging section supported on the upright section spaced from the longitudinal section, and a flange extending upright from the longitudinal section. The shoe defines the other of the track pivots and includes a guide member which slides along and between the longitudinal, upright, and overhanging sections and the track flange. The sash arm overlies the overhanging section when the window is closed.

A snap stud usable in window hardware, such as window operators and window hinges, for releasably pivotally interconnecting a pair of members. The snap stud has a stud extending from a first of the members and provided with an external peripheral groove which mounts a C-ring of spring music wire. The C-ring has a retention position partially extending beyond the periphery of the stud for overlying a second of the members and a compressed release position substantially entirely within the periphery of the stud, with the movement of the C-ring to the compressed release position occurring automatically in assembly and disassembly of said members.
