  • Patent number: 6601715
    Abstract: A load-bearing plank-like member is adapted to be supported by its ends on support members having peg members engageable with complementary apertures in the plank member. The plank member is of hollow cross-section and incorporates at least one internal longitudinal web disposed parallel to the upper, load bearing surface of the plank member, the web being spaced from the underside of the plank member by a distance less than the length of said peg members. Vertically aligned complementary apertures are formed in the underside of the plank member and in the web, whereby when the plank member is engaged with the support member each of the pegs engages with apertures both in the underside of the member and in the web.

  • Patent number: 6463700
    Abstract: A composite gutter guard is adapted for being positioned at an opening of a longitudinally extending, generally U-shaped gutter used for collecting and distributing rainwater runoff from the roofs of residential homes and other buildings. The gutter guard includes an elongate polymer guard panel defining a plurality of spaced filter openings. The guard panel is adapted to extend laterally across the opening of the gutter and longitudinally along the length of the gutter. A polymer-coated mesh layer overlies the guard panel in an area of the filter openings and cooperates with the guard panel to capture and separate debris from rainwater runoff entering the gutter. A heat weld connects the mesh layer to the guard panel.

  • Patent number: 6412250
    Abstract: An elongate modular post cladding element is adapted for cooperating with at least one other cladding element to cover a post. The cladding element includes a panel for being applied to the post, and having first and second opposed end edges and first and second opposed, longitudinally-extending side edges. A female fastener extends along the first side edge of the panel. A complementary male fastener extends along the opposed second side edge of the panel. The female fastener has spaced-apart surfaces forming a generally U-shaped groove having a depth at least twice as great as its width. The groove defines a position adjustment zone for receiving a selected portion of a male fastener of an adjacent cladding element to adjustably position the adjacent cladding element on the post.

  • Patent number: 6226950
    Abstract: A modular cladding element cooperates with an assembly of cladding elements to clad a surface of an underlying structure. The cladding element includes a cladding panel having opposed inside and outside major surfaces, first and second opposed sides, and first and second opposed ends. A removable male fastener is integrally formed along the first side of the panel, and is adapted for entering a complementary fastener of an adjacent cladding element when positioned on the first side of the panel. The male fastener is removable in the absence of a complementary cladding element positioned on the first side of the panel. A first female fastener is integrally formed along the opposed second side of the panel, and defines a first opening adapted for receiving a complementary fastener of an adjacent cladding element positioned on the second side of the panel. A second female fastener is integrally formed adjacent the male fastener on the first side of the panel.

  • Patent number: 6199340
    Abstract: An elongate modular decking plank is provided for assembly on a supporting subfloor together with a plurality of like planks to form a decking structure. The decking plank has a top wall spaced-apart from a bottom wall, and opposing laterally spaced downwardly converging side walls interconnecting the top and bottom walls. An integrally-formed flange extends outwardly from the bottom wall on one of said sides of the decoding plank. The flange includes a fastening portion for receiving fasteners therethrough to the supporting subfloor to mount the decking plank on the supporting subfloor, and a connecting portion for connecting the plank to an adjacent like plank in a manner which permits limited lateral and angular adjustment between adjacent planks. The plank is preferably extruded from high-impact polymeric material, such as PVC plastic.

  • Patent number: 5237775
    Abstract: A sash window construction comprises an outer frame, at least one sash frame supported for sliding movement relative to the outer frame by locating members on the sash frame engageable with carrier members located in channels formed in the outer frame, components of the carrier members being movable between operative positions in which the carrier members are slidable in the channels and the sash frame is secured against release from the main frame, and release positions in which the carrier members are locked against sliding movement and the sash frame may be disengaged from the outer frame. Preferably the sash frame is arranged to be tiltable relative to the main frame, being retained against engagement in its normal position of use and removable from the main frame in its tilted position.
