    Abstract: An improved method of producing surface seeded exposed aggregate concrete upon a subgrade. The method comprises the initial step of pouring a concrete mixture over the subgrade, which is followed by the step of finishing the exposed surface defined by the concrete mixture with a vibrating metal bull float to dispose a quantity of cement/fines paste derived from the concrete mixture at the exposed surface thereof. Thereafter, a quantity of aggregate is broadcast upon the exposed surface of the concrete mixture and subsequently mixed into the quantity of cement/fines paste thereof via the vibrating metal bull float. The exposed surface of the concrete mixture is then finished with a power trowel to facilitate an even distribution of the quantity of aggregate within the quantity of cement/fines paste, which is followed by the application of a surface retarder to the exposed surface of the concrete mixture.

    Abstract: A floor mat has a slip resistant upper surface intended for foot traffic and a backing layer intended to lay across a surface on which the floor mat is supported. The core of the mat is a woven roving sheet of fiberglass. A layer of polyurethane is bonded to the fiberglass, and beads are projected to impact the polyurethane layer when it is soft and tacky. The beads are sintered ceramic beads having a high coefficient of friction. At first, the beads are partially embedded in the polyurethane layer, then the polyurethane is heated to further embed the beads to 60-90% into the polyurethane. This leaves the crowns of the beads exposed, and in combination with the intervening expanses of polyurethane provides a slip resistant surface.

Each of the rails include a base portion supporting a tread surface and a pair of parallel side members connected to the sides of the base portion. Each of the side members defines a passageway. The coupling members are flexible, resilient, and each including a web with longitudinal side margins. Each web has connected to each side margin an arrangement for engaging the passageway of a side member. When the floor mat is disposed on a flat, horizontal floor, the web is at bottommost position in the floor mat.

  • Patent number: 5475951
    Abstract: A shaped or flat article is described, having a skid resistant surface useful on floors, stairs, ladder rungs, ramps and other locations where a highly durable surface is required. The article is prepared by etching and cleaning a surface of the metallic base followed by adhering and fully covering the base, in the area where the skid resistant surface is required, with a flexible mesh layer embedded in a thermosetting resin such as a flexible epoxy resin. Partially embedded in the resin over the mesh are particles of a grit material. One or more additional layers of a suitable coating such as paint may be applied on top of the cured resin for visibility, luminescence, cleanability, and added protection.

  • Patent number: 5207172
    Abstract: A boat deck surface covering comprising at least two layers which are applied one over the other. The layers contain a slow hardening elastic resin, such as epoxy resin, a hardener or curing agent for the resin, and a solid particulate, finely divided filler material of low density. The underlayer contains a coloring agent or pigment for the simulation of white or black gap material, which is exposed through narrow strips or gaps in the top layer, preferably a wood plank-simulating surface layer, to produce a surface covering simulating a wooden plank pattern.

  • Patent number: 5205092
    Abstract: A threshold mat comprising alternating scraper units and wiper units. The improvement is that the wipers, that is strips of carpeting are carried on extrusion carriers and are gripped by their edges via a tightenable clamp incorporated in the scraper unit. The feature of tightening enables different thicknesses of carpet material to be accommodated.

  • Patent number: 5157804
    Abstract: A foot mat comprises a multiplicity of elongated rail members formed by coextrusion of a substantially rigid polymeric material and a compressible polymeric material. Each rail member has a rigid tread-supporting web portion, at least two rigid leg portions, which are adapted to support the tread-supporting web portion stably on a surface, a cushion portion of the compressible material on the bottom of each leg portion, and a pair of rigid bulbous coupling portions of the substantially rigid material, one on each side of the tread-supporting web portion. Each coupling portion is substantially longitudinally coextensive with the tread-supporting web portion and extends generally laterally outwardly from the tread-supporting web portion. A tread member is received on the top of the tread-supporting web portion of the rail member.

  • Patent number: 5103608
    Abstract: An improved stair nosing device especially useful in temporarily darkened stairways is provided which includes a plate member with an upper surface, at least a portion of which is covered by luminescent material. The stair nosing device includes non-slip material attached to the upper surface to provide increased frictional contact with foot traffic relative to the plate member. The non-slip material is attached as spaced apart strips with an upper surface of the non-slip material being higher relative to the plate member. In this way the luminescent material is protected from damage by foot traffic.

  • Patent number: 5054253
    Abstract: A grating mat assembly is disclosed, which is of a generally rigid construction, as distinguished from an articulated, roll-up construction. Unlike conventional rigid grating mats, the structure of the present invention comprises a plurality of slot-like section joined edge to edge in a manner providing for sufficiently rigidity for manufacture, handling and installation, while eliminating the customary longitudinally extending locking bars, utilized in more conventional grating mat assemblies, which add significantly to the cost of manufacture thereof. The slot-like mat sections of the new design are of extruded construction, formed with a horizontal upper ball, widely spaced vertical end walls, and one or more intermediate vertical walls. The vertical walls support the upper wall substantially above a base surface. The opposite vertical end walls of the slot-like sections are formed with tongue and groove structures, such that a pair of adjacent section interfit to provide positive horizontal alignment.

  • Patent number: 5009045
    Abstract: A plastic plank member, for use with a deck arrangement, having a rigid base portion and a tread portion attached thereto which are integrally extruded of suitable plastics. The rigid portion of the plank member is adapted to be secured to an underlying support structure. The tread portion is formed with protrusions projecting upwardly away from the tread and grooves formed therein. The characteristics of the tread result in a sufficiently high coefficient of friction to reduce the possibility of slipping on the plank member.
