Patent number: 4571353Abstract: An improved carpet tile for commercial, industrial or home use. The carpet tile has two straight first and second edges. Its third and fourth edges each have a portion removed to form key sections at the ends and a channel indentation in the middle. The tile when installed registers diagonally with like tiles because key sections from two tiles having adjacent straight edges are received by a channel indentation of each side edge of the tile. Movement of the tile in relation to other tiles is reduced and unsightly continuous edge lines across the carpet surface are eliminated. This invention is particularly useful when applied to free-lay carpet tiles, which use no adhesive to hold them to the underlying surface, because it prevents such tiles from delaminating, curling or warping. The simple shape of the tile allows it to be manufactured and installed quickly and inexpensively.Type: GrantFiled: April 26, 1984Date of Patent: February 18, 1986Assignee: Interface Flooring Systems, Inc.Inventor: Carl I. Gable, Jr.

Patent number: 4546024Abstract: An array of gravity-held-in-place-load-bearing-horizontal-modular-accessible-tiles, composite-modular-accessible-tiles, and resilient-composite-modular-accessible-tiles with flexible joints between adjacent modular-accessible-tiles in which the flexible joints are cuttable, accessible and resealable to provide accessibility to conductors disposed above or below one or more horizontal-disassociation-cushioning-layers, requiring fluidtight-flexible-assembly-joints between adjacent modular-accessible-tiles to assemble the modular-accessible-tiles by gravity, friction, and accumulated-interactive-assemblage into a floating finished floor array without adhering the modular-accessible-tiles to the horizontal-base-surface. A horizontal-disassociation-cushioning-layer provides accommodation for the thickness variations caused by termination and crossing over of layers of conductors and also provides improved impact sound isolation.Type: GrantFiled: June 24, 1982Date of Patent: October 8, 1985Inventor: J.

Patent number: 4536427Abstract: A light-weight contourable core of high strength for inclusion in boat hulls in which the core is sandwiched between facing sheets of resin-reinforced fiberglass. The core is formed by a planar array of block-like modules made of end-grain balsa wood or other material having acceptable properties whose adjacent edges are held together by flexible adhesive joints that have a short elastic limit, such that when the planar core is pressed against a contoured surface for lamination thereto, the resultant stresses cause the joints to stretch beyond their elastic limit to an extent necessary to permit the modules to conform to this surface. There is no spring back when the pressure is released, and the modules, therefore, maintain their conformed positions.Type: GrantFiled: March 26, 1984Date of Patent: August 20, 1985Assignee: Baltek Corp.Inventor: Henri-Armand Kohn

Patent number: 4535015Abstract: A large water and air impervious textile panel suitable for use as a pond liner, tarpaulin, or the like, is constructed from a plurality of smaller panels. Each small panel comprises a weft inserted warp knit fabric having reinforcing substrate strips disposed at the selvedge edges thereof, and the strips spaced from each other along the width of the fabric. The small panels are chemically finished by first applying an adhesive system such as an isocyanate, and then a thermoset or thermoplastic polymer coating. The selvedge edges are prepared for attachment to each other by buffing and then applying an adhesive cement. The buffing does not extend along the width of each small panel any further than the width of the selvedge reinforcing substrate strip. Adjacent selvedge edges of the small panels are overlapped, and then attached to each other with the cement adhesive. Alternatively the overlapped small panel edges may be ultrasonically or thermally bonded to each other.Type: GrantFiled: March 2, 1984Date of Patent: August 13, 1985Assignee: Burlington Industries, Inc.Inventors: Jeffrey W.

Patent number: 4436779Abstract: A modular surface having an important use as a sports deck, and particularly for ball sports like tennis. The surface is built up of a number of generally square tiles in which the play surface is supported by a large number of support pegs intended to rest on an undersurface. The tiles are flexible so that the support pegs can remain in contact with the undersurface even if it is not perfectly plane, assuring consistent ball bounce. A special arrangement of expansion joints gears the ability of the tile to absorb expansion and contraction resulting from temperature changes to the geometry of the tile to: (a) keep the pegs on the ground even in the presence of temperature changes to assure consistent ball bounce, and (b) keep the play field itself from expanding or contracting without the need for anchoring it to the undersurface.Type: GrantFiled: July 2, 1982Date of Patent: March 13, 1984Inventors: K. Anthony Menconi, Joseph F. Gribauskas, Jr.
