Abstract: A transparent structure provided with a transparent support wall and a transparent mobile wall. The mobile wall is articulated on the support wall by at least one hinge mechanism. Each hinge mechanism has an immobile element as well as a mobile element and a pivot which articulates the immobile element on the mobile element, the pivot extending according to an axis of rotation, the axis of rotation being offset relative to the seal transversely, while being situated on a plane orthogonal to a immobile second face and not passing via the seal, the axis of rotation being offset relative to the seal in elevation, and not being incorporated in the opening which can be closed by the mobile wall.

Abstract: A frame for a window intended to serve either as a stationary frame or as a sash frame according to the invention comprises an insulating abutment list on a side surface of at least one of the top, bottom or side members intended to face a side surface of another frame of the window. The insulating abutment list is made from a material having a thermal conductivity of less than 0.08 W/(m·k), preferably less than 0.04 W/(m·K). Preferred materials for the insulating abutment list are expanded polystyrene (EPS) or extruded polystyrene (XPS). In a window with such a frame, an insulating abutment list on the sash frame preferably extends from hinge part to the bottom member of the sash frame and an insulating abutment list on the stationary frame preferably extends from a hinge part to the top member of the stationary frame.

Abstract: In a tiltable or pivotal window in which the frame and sash side members that are perpendicular to the axis of rotation have oppositely facing abutment surface sections on either side of the axis area, said abutment surface sections merge smoothly into each other through an abutment surface section formed as a helical surface of about 180.degree.. A continuous weather strip may be provided on one or both of the abutment surfaces. If such strips are provided on both surfaces, they may be magnetic with opposite transverse polarization to improve tightness and minimize sliding contact between the strips in the helical surface area.

Abstract: A door system of the swinging type to neutralize air draft effects on the door, which is conceived to allow panic exit and to psychologically induce the user to pivot the latter in a predetermined direction. This door system includes a pair of wings or panels having a releasable magnetic connection allowing normal bodily pivoting of the two wings as a simple swinging door and also allowing, for instance under panic, outward opening of the wing which normally opens inwardly. This door system includes a stopper and a door frame relatively arranged to define an oblique closing position for the door, and also includes a resilient strip of adjustable resilience engaging the stopper to prevent inadvertent opening of the panic wing.

Abstract: An annular outer frame mounts the assembly in a vehicle. A pair of pivots rotatably support an inner frame (which mounts a window) for rotation about an offset axis between open and closed positions. The pivots can support a frameless window. One of the pivots has a spring-like arm actuated by manually twisting a handle. The arm grips a pivot stud which locks the inner frame or window in a desired position or by proper setting, the gripping pressure exerted by the arm on the stud can provide for a clutch action.

Abstract: A vent window assembly having a seal with both side and edge sealing surfaces; pivot means support the glass and are spaced away from the opening so that no part pierces the seal which allows the seal to be an extruded piece continuous in the opening; the construction of the pivot means provided for the same to be used as a lock to hold the glass in the closed or in any open position or used as a clutch as by holding the glass in an open position but permitting the glass to yield upon impact.
