  • Patent number: 4907387
    Abstract: A combination of a deck having a plurality of spaced apart wooden deck members on the surface thereof wherein each deck member has a top, sides and a bottom and an apparatus for covering the deck members. The apparatus comprises a plurality of channel shaped members each of which has a flat top portion for covering the entire top of one deck member. The flat top portion has a rough top surface to inhibit persons from slipping on the deck. The channel shaped member also has first and second side portions which extend generally perpendicular to the top portion. The first and second side portions are generally parallel to each other and are spaced apart to receive one deck member therebetween. The side portions of the channel shaped member extend over the sides of the deck member from the top to the bottom thereof.

  • Patent number: 4866808
    Abstract: An improved rollable floor mat comprising a plurality of substantially U-shaped extruded plastic profiles having straps attached to the underside thereof. The profile has a center portion with a cross-sectional area smaller than the cross-sectional area of the bottom portion of the U-shaped profiles. The bottom surface of the bottom portion of the U-shaped profiles are attached to the plastic straps to form the mat into the desired configuration. The plastic profiles, with bristle-like filaments extending from the top thereof, are flexible in two directions about the smaller cross-sectional aread center portion to provide a scraping action in two directions of the bristle-like filaments to the soles of shoes and boots of persons walking on the mat.

  • Patent number: 4804570
    Abstract: An articulated floor mat structure is disclosed, in which a series of rigid, slat-like elements are hinged together and locked to prevent lateral movement, to form a mat structure that can be rolled up. The individual structural elements are shaped to provide for slide-in or snap-in assembly of tread strips, along their upper surfaces, and pad strips, along their lower surfaces. Edge strips are secured along the side edges of the mat assembly in an advantageous manner, to retain the tread strips and pad strips in assembled positions. An arrangement of integral loop tabs on the edge strips and integral hook tabs on the structural members greatly expedites the assembly process and correspondingly reduces the cost of manufacture, without compromising performance.

  • Patent number: 4715743
    Abstract: A tile for positioning on walkways, crosswalks and other areas of pedestrian traffic for providing direction and warning to visually handicapped persons. The tile comprises a flat plate having a chamfered edge and including raised bumps coupled to a top surface of the plate and projecting upward therefrom to a maximum height of less than 8 millimeters. A flowable adhesive used at the chamfered edge provides for a tapered seal around the tile or for formation of an expansion joint between two contiguous tiles. The bumps are configured as truncated structure having a larger base and tapered to a top surface which bears the foot traffic. A bottom surface of the tile includes a uniform adhesive layer which enables attachment of the tile to a street surface. A system of tiles for assisting visually handicapped persons across the street is also disclosed and includes a combination of dot and bar tiles oriented to give direction to the pedestrian.

  • Patent number: 4662972
    Abstract: The present invention defines methods of forming a non-skid surface on a base member, wherein the base member may consist of a wood, plastic, metal or concrete surface structure. One method includes applying one or more coats or layers of epoxy resin to one surface of a wood base member. After the epoxy resin is set, a first coat of polyurethane is applied thereover at a thickness determined by the size of the grit material that is disseminated in the first coat of polyurethane, whereby the upper portion of the grit is exposed so as to be covered by a second polyurethane coat applied over the first coat of polyurethane, the grit being locked within and between the two coats of polyurethane. An additional method includes the step of affixing a fiber/cement panel to the base member and applying the first polyurethane coat to the surface of the fiber/cement panel, followed thereafter by the grit and the second coat of polyurethane, whereby a non-skid surface is established thereon.

  • Patent number: 4272211
    Abstract: A wear-resistant element, particularly in the form of a slab intended to be used as covering in areas exposed to excessive wear. The slab includes a hard wear metal of a hardness exceeding 400 Brinell, said wear-metal being in the form of granules which are embedded into a bonding agent consisting of synthetic resin, ceramic materials, rubber, or a combination of these materials. Preferably, the granules are arranged to agglomerate adjacent the wear face of the slab, whereas the concentration of wear metal towards the bottom of the slab is essentially nil. The resulting slab thus uses less amounts of the expensive wear-resistant material, and at the same time it is lighter than prior-art slabs and easier to manufacture.
