Abstract: A blade member for use in a shutter curtain assembly. The blade member is of a given height and has a top, a bottom, a first edge and a second edge. A first semi-cylindrical interlocking portion extends along the first edge. The first portion includes a pair of inwardly-directed tangs which extend from opposite sides of the semi-cylinder. A second semi-cylindrical interlocking portion extends along the second edge and is sufficiently smaller in diameter than the first portion. A second interlocking portion of a succeeding blade member may be slidably inserted into the first interlocking portion. The second portion includes a pair of outwardly-directed tangs which abuttingly engage the inwardly-directed tangs of the first interlocking portion. A series of blade portions are thus interconnected and form a continuous shutter curtain which is selectively unfolded or retracted.

Abstract: A novel folding storm shutter system includes an overhead header presenting a track and a pair of laterally spaced abutment surfaces.

Abstract: A window assembly for a vehicle cab having first and second frames and a window horizontally divided into upper and lower sections. The upper section of the window is pivotally mounted to the top rail of the second frame which is totally surrounded by the first frame. The lower window section is hinged to the bottom of the upper window section and has a guide member on its bottom edge which mates with side guide rails formed in the second frame. The window is opened and closed by hydraulic cylinders which positively position and retain the window in a desired position regardless of the vibration or rocking motion experienced by the vehicle as it traverses over uneven terrain. Furthermore, the entire second frame can be opened by pivoting it about the upper edge of the first frame. In so doing, an alternative escape route is provided for leaving the confines of the cab.

Abstract: A closure includes a plurality of vertical panels suspended from an overhead support and successively joined to one another by interlocking, alternate outer and inner pivot elements attached to the panel lateral edges. When the closure is collapsed the panels are folded about the pivot elements into a stacked, parallel diposition. Improved articulation between the panels is achieved by means of unique outer and inner pivot element components including respectively, a curved groove and a curved arm, both describing an arc of approximately 270.degree.. Female elements on the base of each pivot element cooperate with mating male elements joined to each panel lateral edge to allow ready assembly therebetween, with the panels themselves comprising either metal and/or a plastic composition.

Abstract: A folding closure having an emergency folding door therein which has a height less than the height of the closure. A folding top closure section is provided in the closure above the folding door. Means detachably connect the folding door and the folding top closure section together. The arrangement allows the folding top closure section to guide the folding door about corners when folding or unfolding the closure.

Abstract: An improved folding closure consisting of a plurality of panels joined at adjacent vertical sides by hinges. Means are provided on each panel for carrying a sweeper strip across the bottom of the closure. The carrying means include means for strengthening the bottom of each panel.

Abstract: A hanger is provided for suspending a slat of a multi-slat folding partition from an overhead track. The hanger has a shaft with a head at its upper end and a tang at its lower end. The tang is for engaging a hole through the top of the slat. A clip is on the shaft for holding the tang in the hole in the slat when the clip is in its lower position. A bogie is mounted on the shaft between the clip and the head of the shaft. The bogie engages an overhead track for suspending the slat for movement along the length of the track.

Abstract: A panic bar assembly for use with a folding door. The panic bar assembly has a panic bar moveable between an operative, horizontal position, with the door unfolded, and an inoperative diagonal position with the door folded. The panic bar moves between its operative horizontal position and its inoperative, diagonal position simultaneously with the folding and unfolding of the door.

Abstract: A folding screen is formed by a plurality of successively hinged, rigid, radiation-controlling planar panels supported so the screen can be opened (or extended) and closed (or collapsed). Adjacent panels are supported only at their edges, by a hinge member having symmetrical back-to-back tubular channels. The hinge member possesses sufficient rigidity to permit hinged, side-by-side coaction of the panels from a stacked, generally vertical relationship when the screen is collapsed, to an undulating planar relationship when the screen is opened, which relationship is essential if the screen is to be collapsed without binding. The screen is translatable on a pair of parallel, mono-level tracks, and operated by a flexible drive member extending along a rail and connected to the screen's leading ("lead") panel.A novel skylight includes a curb assembly, a "bubble" (or "dome") and a folding screen translatable to-and-fro below the bubble.

Abstract: A folding door, of the kind composed by an array of wooden slats connected by intermediate hinge elements; the intermediate hinge elements are of wood, preferably of the same color and grain of the wood the slats are made of, and a metallic hinge element is hidden within the strips of wood interposed between any two wooden slats so that the external appearance is that of an all-wooden assembly both when the door is outstretched and when it is folded.

Abstract: A drapery and support combination is provided for a slat type ("woven wood") curtain wherein spacers between the slats are connected to the support elements in such a way that, in the fully closed position of the curtain, the spacers hold the slats at the correct angle independently of the looseness of the curtain material which hinges the slats to each other. The spacers are flat and arranged in a vertical plane so as to present an attractive appearance and not to interfere with opening or closing the curtain. The end slats are adapted to pivot on a fixed axis which may be either on the centerline of the slat, or, on the outer margin of the end slat in which latter case, the end slat is supported at a second point which slides relative to the curtain rod along an arcuate path the center of which is on the pivot axis of the end slat. One or more additional slats may be added to the fixed outer margin in order to extend the curtain coverage back to a wall.

Abstract: A folding door or other closure comprising a plurality of panels of extruded material each having a male hinge element along one edge thereof and a female hinge element along the other edge thereof with each panel being of unitary, one-piece construction. The hinge elements are so constructed that interconnection and separation of the panels is attained by longitudinal sliding movement of the male and female hinge elements in relation to each other. A locking means is provided in the form of a projecting means associated with one of the hinge elements which engages with recess means associated with the other hinge element to preclude relative longitudinal movement between adjacent panels while permitting relative pivotal movement between adjacent panels.

Abstract: A door or other closure, partition or the like incorporating a plurality of substantially rigid panels having interengaging hinge structures formed unitarily along each side edge thereof with certain of the panels being supported by roller equipped carriage assemblies adapted to engage an overhead track. The hinge structures include means permitting relative vertical movement between adjacent panels to enable quick assembly and disassembly. An end clip for the hinge structures prevents relative vertical movement between adjacent panels after assembly with the clip being removable for disassembly. The overhead track is connected to a ceiling supported bracket or rail by an insert or latch which enables lateral engagement of the track with the bracket or rail to facilitate quick assembly and also to enable lateral disengagement of the track from the bracket or rail to enable quick removal or disassembly.
