Abstract: An energy saving window system operates selectively in different seasons and climatic conditions to optimize transfer of the sun's radiation through the window into an interior space. Two sets of diffraction gratings are deployed, with two mode settings--a summer or capture mode and a winter or transmittance mode. In the summer mode, transfer of heat into the interior is undesirable. Unwanted heat rays are redirected to a scupper by additive diffraction through two diffraction gratings in series. The scupper redirects the undesired radiation to a heat sink or back out through the window. In the winter mode, transfer of heat into the interior is desirable. By repositioning the two diffraction gratings so that their deflections are subtractive, the sun's rays are redirected to be essentially undiffracted so as to miss the scupper and enter the room. The essentially undiffracted light rays are acceptable as a view and are effectively unblocked as to solar heat gain.

Abstract: A retractable cover for an opening of an automotive bay pit wherein the retractable cover is formed by movable and stackable panels. The panels are normally positioned adjacent one another. Each panel includes supporting and spanning edges. Positioned on the supporting edges are slide rails. The slide rails are slidable in two horizontal directions in tracks of the automotive bay pit. The ends of the slide rails are inclined, and abutting ends of the slide rails of adjacent panels are parallel to one another. Because the abutting ends are parallel, an operator's application of a strictly horizontal force to a panel causes the panel to wedge under or slide over an adjacent panel. Therefore, the operator is not required to apply any vertical lifting force to a panel to create an opening in the cover. The operator may move any panel in the cover and move it in either horizontal direction to create the opening in the cover.

Abstract: An extendable arm has a first arm portion, a second arm portion extendable and retractable relative to the first arm portion to extend and contract the arm, and a flexible elongated pulling element having opposite ends connected to the second arm portion and passing around a rotatable spool secured in position on the first arm portion. Rotation of the spool causes the second arm portion to extend or retract relative to the first arm portion.

Abstract: The mechanism comprises longitudinal rails and, for each door, a double slide assembly of which a first slide slides along the rails and a second slide, constrained to the door, moves at right angles to the first slide between a retracted position in which the door is closed and an extracted position in which the door is opened, at a distance from said first position at least equal to the thickness of the door or a multiple thereof. A longitudinal traverse of the slide assembly is allowed only when the second slide is in the extracted position with respect to the first. The retracted position is forced by spring means between the second slide and the first slide. The width of the slide assembly is smaller than the width of the door, generally being half, a third or a quarter thereof.

Abstract: A storm shutter for protecting glass windows and doors employs one or more transparent unbreakable panels having edges effectively increased in thickness to be retained in respective tracks in the shutter frame, the track having openings narrower than the thickened panel edges. To accommodate different coefficients of thermal expansion for the panel and frame, the track cross-sectional area is considerably larger than the thickened panel edge, yet the narrowed track opening retains the thickened edges, even if the panel is bowed by applied forces. Edge thickening may be effected by securing strips of the panel material along the panel edges. The shutter frame is pivotably mounted on a casing, and a retainer is slidable on the casing to lock or release the frame for pivoting relative to the casing. If the panel is movable along its tracks, a motor has a drive shaft fixed to the casing and about which support strips are wound to pull on the panel.

Abstract: An apparatus for securing telescoping sliding panels, which are essentially oriented in parallel, vertical planes, against movement perpendicular to their sliding directions, includes a track, parallel first and second carriages which retain the lower edge of each panel and ride along the track, a lip projecting from the first carriage having an upturned free end, a lip projecting from the second carriage, having a downturned free end which extends between the first carriage and the upturned end of its lip. The carriage for each panel preferably includes a body portion which is tubular and has wheels mounted beneath it and gripping members projecting from the top of it for holding a vinyl channel which receives the lower edge of the panel. The track has an upper surface with channels recessed into it for guiding the carriages. An edge of the track is turned upward at a right angle to form a wall for retaining the carriages. The wall is provided with a lip described above.

Abstract: The invention relates to a pivotable glazing for a balcony. There are previously known balcony glazings which comprise four or more panes which move in an overlapping manner on two adjacent tracks. Such a structure requires considerable sealing and frame structures which detract from the outer appearance of the building. Furthermore, the balcony aperture can be opened at maximum 50%, and it is difficult to wash the outer surfaces of the panes. According to the present invention, these disadvantages are eliminated by fitting all the panes of glass adjacently in the same double-rail track. At the upper edge of each movable glass pane (1) there are two slides (3, 4), of which one moves on a straight outer rail and the other on an inner rail, which curves inwards and towards the side wall (13) of the balcony. Within the curved portion (18) of the inner rail the trailing edge of the pane turns inwards and the pane can be opened against the side wall (13) of the balcony.

Abstract: A pair of telescoping panels covers the bed of a pickup truck. An axle member at the trailing end of the rear panel is biased to lift that trailing end upwardly so that it can clear the tailgate of the truck when a latch is released and so that the rear panel can be slid forwardly when so released. A latch at the leading end of the forward panel similarly releases an upwardly biased axle so that the leading end of that panel can clear the forward wall of the truck bed when it is desired to slide the front panel rearwardly. A third axle is positioned at the leading end of the rear panel. All three axles carry wheel members at their opposite ends that are mounted for lateral movement within longitudinally extending tracks mounted to opposite side walls of the truck bed. The lateral moveability allows the structure to be positioned on differing models of pickup trucks. The panels are arched and ribbed for structural strength.

Abstract: A collapsible double door assembly includes a number of serially connected panels each provided with a pair of inwardly and outwardly deviated pivotal suspension rollers, a horizontal guide rail constituted by an inner rail member and an outer rail member arranged in parallel in close proximity for separately guiding the suspension rollers, and one or two door storage areas extending perpendicularly from the guide rail at one or both ends thereof and formed by separating and independently bending the two rail members with different radiuses of curvature each defining an arc of a quarter of a circle. The radius of curvature of the outer rail member is relatively greater than that of the inner rail member. The distance between the two rail members in a door storage area is slightly smaller than the distance between the two suspension rollers of a panel.
