The invention relates to a glass element (200) including at least one insulating glass panel including at least one first (10) and one second (11) glass sheet combined with one another via a spacer (12) which keeps same spaced apart from one another, said spacer extending along the side, upper and lower edges of said two glass sheets and between said at least two glass sheets, at least one inner space (15) including a layer of an insulating gas and closed by a first (13) and a second (14) peripheral seal arranged around said inner space, and at least one frame (201) which supports said at least one insulating glass panel, said frame including (i) a stationary bracket (21) and (ii) a movable bracket (22) which is hinged on the stationary bracket and which allows the opening and/or the closing of the glass element. Such a glass element includes a spacer (12), the first (13) and the second (14) peripheral seal extending along at least one of the side edges of said at least two glass sheets are formed from a transparent resin, and said movable bracket is devoid of at least one side crosspiece.

A female locking post for the free end of a folding closure section, with an inner side for connecting the post to the free end, and an outer side opposite the inner side. Two opposed connecting walls connect the inner and outer sides together. An interior wall, spaced from both the inner and outer sides, extends between the connecting walls. A post opening, preferably extending the length of the post, is provided in the outer side between the connecting walls providing access to the interior wall. An operator with a lock bolt is movably mounted on the interior wall, the operator movable along the interior wall between an unlocked position where the lock bolt is within the post and a locked position where the lock bolt projects from an end of the post. A folding closure incorporating the female post is also described.

An apparatus including a receiving channel and a locking clip for securing a folding door in a closed configuration. The receiving channel is mounted to a side of a door frame associated with a closed configuration of the folding door. The locking clip is mounted to the leading edge of the folding door. The locking clip includes sides that extend past sides of the leading edge of the folding door so as to create a ledge on each side thereof. The receiving channel includes cleats on inner walls thereof. The cleats engage the ledges to secure the locking clip within the receiving channel in a closed configuration. The locking clip may be mounted to a center of the leading edge. The receiving channel may traverse substantially the height of the door frame.

A door opening/closing device includes a shaft member installed on a first door panel side so that it cannot rotate. Both ends of a torsion spring in the door opening/closing device are latched to a second door panel side via torsion spring latching walls, and a center portion of the torsion spring is latched to the first door panel side via a latched member, a latching portion, and the shaft member. When the first door panel and the second door panel are pulled from the state in which the doorway is closed, the first door panel and the second door panel fold about an outside cylindrical member as center. The outside cylindrical member rotates relative to the shaft member. First and second coil portions deform elastically in the direction that they are each wound tighter, and the first and second door panels are opened and the doorway is opened.

A door operating system or door opening and closing apparatus comprising at least one motive source, a linkage assembly and a door. Preferred door operating systems will include two linkage assemblies, two doors and two motive sources, one for each door. Each motive source is preferably attached to an interior facing surface of a frame of a structure and the door is pivotally attached to an exterior facing surface of the frame of a structure. Each linkage assembly operatively connects the respective motive source to the respective door. By having the motive source attached to the interior facing surface of the frame, doors of the operating system can preferably be opened the full width of the frame opening to maximize available vehicle clearance.

An accordion type folding door system having a plurality of elongated panels hinged together along their longitudinal side edges into a pleated or zig zag arrangement, the folding panels being interconnected by a hinge assembly. The hinge assembly is disposed between and interconnects a pair of adjacent panels, each of the pair of interconnected adjacent panels including a side edge having longitudinal groove and an extension flange, wherein the hinge assembly includes a hinge pin and a plurality of hinge knuckles disposed vertically end-to-end in alternating arrangement on the hinge pin, the hinge knuckle having a tubular central opening for accepting the hinge pin, an outwardly extending tongue for connecting to a corresponding longitudinal groove in an adjacent panel in a tongue and groove connection, and an outwardly flared wedge that extends beyond the extension flanges of the panels, whereby the wedge cooperates with the extension flanges to limit angular folding extension to a maximum desired angle.

An automatic closing structure is disclosed, which is installed between a sash and a corresponding object, wherein the sash is pivotable relative to the corresponding object; the sash includes a frame and a plurality of turnable slats which are arranged in parallel in the frame; the automatic closing structure has a cord which is adapted to automatically close the slats, wherein the cord can be easily assembled into the automatic closing structure, and a tightness thereof can be adjusted.

A powered folding door or window system includes at least two rigid panels that are linked together by at least one vertical hinge/pivot to fold between a closed state, where the panels extend across an opening, to an open state, where they are retracted to one side of the opening and stacked against each other. The system incorporates a motor and a drive belt mechanism as primary means for driving the panels. The system further includes a powered actuator on one of the panels and a co-operative element on a linked adjoining panel; whereby the powered actuator cooperates with the co-operative element on the linked adjoining panel to move the linked adjoining panel and said one panel about the vertical hinge/pivot linking them; whereby the powered actuator may start the opening of the door or window system and/or complete the closing of the system.

A locking post for a closure, the post having front and rear walls joined at their sides by two side walls to form a tubular post having a generally quadratic cross-sectional shape. Each side wall has a groove therein, the groove parallel to the longitudinal axis of the post, and wide enough and deep enough to at least partly receive a locking element carried by the post. The sides of the groove also provide handles which can be gripped to move a closure the post is mounted on.

A barrier door system to control movement of persons through an opening in an interior space of an aircraft. The barrier door system having a frame with outer members that extend around a gap. A barrier door has a first panel and a second panel that are pivotally connected together with the barrier door pivotally connected to the frame. The barrier door is movable between a stowed position and a deployed position. The stowed position includes the first panel and the second panel folded together in an overlapping configuration and positioned in the gap in the frame and away from the opening. The deployed position includes the first panel and the second panel positioned away from the gap and extending across the opening.
