Patent number: 6065255Abstract: A structure for mounting a planar array of photovoltaic panels to a roof is formed from a set of parallel spaced juxtaposed rails which are intersected by a set of parallel spaced juxtaposed runners that extend perpendicular to the rails. Both the runners and the rails are formed of sheet metal and are shaped in cross section so as to partially surround a space. Both the rails and the runners have upwardly opening apertures bordered by flanges. The flanges of the rails are coplanar with the flanges of the runners. The photovoltaic modules rest on the flanges, thereby covering the apertures and enclosing the space within the rails and the runners. This space serves as a protective raceway for the electrical interconnections and wiring. Because the entire structure is a single electrical conductor, grounding of the modules is simplified. Compared to other mounting systems, the structure is lighter in weight, simpler to install, extremely strong, and protective of the electrical interconnections.Type: GrantFiled: December 7, 1998Date of Patent: May 23, 2000Assignee: Kyocera Solar, Inc.Inventors: Michael J Stern, Gilbert Duran, Kevin K.

Patent number: 5157892Abstract: The invention involves a structural interlocking joint system for structural panels used in building construction. A skeleton is formed of interlocking ribs which engage panel skins which are grooved in a pattern to receive the edges of the interlocked ribs. The grooves of each panel skin are formed with their edges angled away from the groove to provide both a wider opening for insertion of the rib skeleton into the grooves, and to provide, after such joining insertion, a reservoir for any excess glue forced out by the joining process. Along the longitudinal edges of the ribs is formed a uniform channel which provides a defined reservoir for glue of substantially even width and depth between the edge of each rib and the bottom of the corresponding groove within the skin. Thus, in the insertion of a rib within a groove, the glue is directed into a substantially uniform strip within the rib edge channel, maximizing strength and minimizing localized glue overflow.Type: GrantFiled: November 22, 1991Date of Patent: October 27, 1992Inventor: Ronald R.

Patent number: 4945689Abstract: Collapsible gridworks for confining fluent materials within cells defined by the gridworks to form stable columns capable of withstanding substantial vertical and horizontal loading are each made up of a plurality of interwoven/intermeshed longitudinal and latitudinal strips. In the preferred embodiment, the strips include slots formed on alternating sides thereof, with the gridworks being formed by interweaving the slots on one side of the longitudinal strips with corresponding slots on the opposite side of the latitudinal strips such that the gridwork is defined by mechanically interlocking joints which permit motion for collapsing the gridwork into both a multilayer strip and a substantially flat sheet. The open state of the grid work and both of its collapsed states are similarly stable and can be freely handled without fear of the gridwork falling apart.Type: GrantFiled: November 9, 1988Date of Patent: August 7, 1990Inventor: Robert H. Johnson, Jr.

Patent number: 4943534Abstract: A tray assembly for a germination floor assembly having a perforation tray sheet affixed to a rectangular frame assembly. The frame assembly includes a pair of parallel side members interconnected by a pair of end cross frame members. A plurality of longitudinal ribs extend parallel to the side members between the cross frame members. Reinforcing cross bars further extend between the side members and the longitudinal ribs. The cross frame members and reinforcing cross bars have a unique configuration to provide unimpeded flow of liquid wash through the tray assembly during cleaning. A tray assembly is attached to an adjacent tray by a bolt assembly. The tray assembly may be attached to supporting I-beams by hold down clamps. In one embodiment risers are employed for enhanced free flow of liquid wash during cleaning.Type: GrantFiled: November 28, 1989Date of Patent: July 24, 1990Inventor: Norman Andreasen

Patent number: 4928471Abstract: An improved grating construction of the type intended for closing or flooring an opening. The construction preferably is formed of aluminum and includes a plurality of spaced, parallel, elongated bearing bars and a plurality of spaced, parallel, elongated, transversely extending crossbars. Each bearing bar has a generally flat, rectangular shape and has a plurality of spaced cutouts formed along a top longitudinal edge thereof. Each cutout comprises an upper rectangular-shaped portion and an outwardly flared lower portion. Each crossbar has a rectangular-shaped top portion and an outwardly flared lower portion, which portions are complementary in shape and size to the upper and lower portions of the bearing bar cutouts. The crossbars are slideably received within a plurality of transversely aligned bearing bar cutouts. The crossbars are deformed or swaged at locations adjacent to and on opposite sides of the cutouts engaged by the crossbars to lock the crossbars in the bearing bars to form the grating.Type: GrantFiled: June 8, 1988Date of Patent: May 29, 1990Assignee: Ohio Gratings, Inc.Inventor: David W. Bartley

Patent number: 4907389Abstract: A lattice consisting of first and second flexible resilient criss-crossed strips each having beveled edges and mating dovetail cutouts oriented in face-to-face relationship with the dovetail cutouts of each of the strips having dovetail sides engaging the beveled edges of the other of the strips. A lattice with criss-crossed strips with one strip having dovetail cutouts with sides which engage mating beveled edges of the other strip. Lattice structures of the foregoing types which utilize hollow strips.Type: GrantFiled: January 22, 1988Date of Patent: March 13, 1990Inventor: Frederick M. Pettit

Patent number: 4903444Abstract: A floor grating assembly is disclosed, which comprises tread rails arranged in closely spaced parallel relation and held by spacer bars. The spacer bars, which are notched, are inserted in alignment openings of preferably triangular shape in the tread rails. After insertion, the spacer bars are rotationally reoriented to a position securing the tread rails in spaced apart relation. Flange means extending along the lower edges of the spacer bars are locally deformable into locking notches formed in the alignment openings. The spacer bars are thus locked against rotation out of their operative positions. Manufacturing economies and structural improvements are realized.Type: GrantFiled: October 3, 1988Date of Patent: February 27, 1990Inventor: Fred P. Berndt, Jr.

Patent number: 4894974Abstract: A structural panel for use in building construction and other applications has an internal rib structure with the ribs interlocked to form a two dimensional matrix. The ribs have tabs that are fitted into openings of facing sheets of the panels. This structure results in a strong prefabricated building panel.Type: GrantFiled: July 5, 1988Date of Patent: January 23, 1990Assignee: Walter J. JaworskiInventors: David Mayhew, E. Nolan Scheid
