Patent number: 5458179Abstract: 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.Type: GrantFiled: August 29, 1994Date of Patent: October 17, 1995Inventors: Glen Magaldi, Gregory Weeks

Patent number: 5097883Abstract: A novel folding storm shutter system includes an overhead header presenting a track and a pair of laterally spaced abutment surfaces. The system includes a plurality of trolley supported shutter members which are rotatable about a vertical axis. The system further includes a sill having a guide slot which is disposed beneath the track in alignment therewith. The sill also has a pair of laterally spaced abutment surfaces. An abutment contacting element is disposed at each corner of each shutter member so that when the shutter system is deployed the contact elements come into contact with the abutment surfaces to rigidify the structure. Trolley mechanisms are provided for supporting the trolley supported shutter members from a location midway between the edges of the shutter member so that the entire assembly is evenly balanced to facilitate maneuvering and deployment of the system.Type: GrantFiled: April 30, 1991Date of Patent: March 24, 1992Assignees: James W.

Patent number: 4443035Abstract: 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.Type: GrantFiled: November 20, 1981Date of Patent: April 17, 1984Assignee: Deere & CompanyInventor: Karl L.

Patent number: 4386645Abstract: 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.Type: GrantFiled: February 10, 1981Date of Patent: June 7, 1983Assignee: Cornell Iron Works, Inc.Inventors: James E.

Patent number: 4328853Abstract: 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.Type: GrantFiled: December 21, 1979Date of Patent: May 11, 1982Inventors: George R. Gall, Charles R. Gates

Patent number: 4284118Abstract: 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.Type: GrantFiled: August 14, 1979Date of Patent: August 18, 1981Inventor: Sergio Ceron

Patent number: 4274467Abstract: 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.Type: GrantFiled: April 5, 1979Date of Patent: June 23, 1981Assignee: Kenney Manufacturing CompanyInventor: Paul E. Comeau

Patent number: 4228841Abstract: 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.Type: GrantFiled: June 4, 1975Date of Patent: October 21, 1980Assignee: Panelfold Doors, Inc.Inventor: Guy E. Dixon

Patent number: 3972365Abstract: 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.Type: GrantFiled: April 13, 1972Date of Patent: August 3, 1976Assignee: Panelfold Doors, Inc.
