Abstract: An ergonomic handrail comprises an elongated metal retainer of substantially uniform cross-section along its length and having a body portion, upper and lower flange portions extending upwardly and downwardly, respectively, from the body portion, an upper web portion extending upwardly from the body portion from a juncture therewith rearwardly of the upper flange portion and defining with the upper flange portion a slot that opens generally upwardly, and upper front and rear arcuate arm portions extending upwardly from a common juncture with an upper edge of the web portion and defining the major portion of substantially circular cylindrical surface except for a space between upper edges thereof. An elongated bumper cover member of an impact resistant substantially rigid polymeric material and of substantially uniform cross-section along its length is received in captured engagement by the flange portions of the retainer.

Abstract: An ergonomic handrail adapted to be mounted on a wall in spaced-apart relation therefrom by means of mounting brackets and comprises an elongated metal retainer of substantially uniform cross-section along its length and having a channel-shaped body portion, upper and lower flange portions extending upwardly and downwardly, respectively, from the body portion, a web portion extending upwardly from the body portion from a juncture therewith rearwardly of the upper flange portion and defining with the upper flange portion a slot that opens generally upwardly, and front and rear arcuate arm portions extending upwardly from a common juncture with an upper edge of the web portion and defining the major portion of substantially circular cylindrical surface except for a space between upper edges thereof. An elongated bumper cover member of an impact resistant substantially rigid polymeric material and of substantially uniform cross-section along its length is received on the retainer.

Abstract: A gasket for a flush expansion joint cover comprises a longitudinally continuous central body portion and two longitudinally continuous side portions, one at either transverse edge of the central body portion. The central body portions and the side portions are comprised of a colorable thermoplastic rubber and are co-extruded to form an integral gasket structure. The side portions, which are adapted to keylock with mating grooves in structural members of the expansion joint cover, are harder than the central body portion to enhance retention of the gasket in place during use. The central body portion has a cellular core structure and a slightly concave upper surface to remain substantially smooth and flush with adjacent surfaces throughout the complete movement cycle of the expansion joint.

Abstract: A floor mat is composed of a multiplicity of rigid elongated rails arranged parallel to each other, each rail having a body portion adapted to receive a tread member and a coupling portion by which it is joined to an adjacent rail. The body and coupling portions are found by extrusion of a rigid high-impact strength thermoplastic polymeric material and are joined by a living hinge of a highly flexible thermoplastic elastomer formed by coextrusion with the body and coupling portions. Each rail includes at least two ribs along its underside laterally spaced apart from each other and adapted to support the rail on a surface, each rib being formed by coextrusion with the body and coupling portions and the living hinge of a soft, compressible thermoplastic polymeric material and serving as a cushion and an anti-slip element of the mat.

Abstract: A panel wall system is composed of a multiplicity of rectangular panels arranged in closely spaced relation in columns and rows such as to define vertical junctures between horizontally adjacent panels and horizontal junctures between vertically adjacent panels and affixed at their upper edges to horizontal support members by mounting clips and joined at each vertical juncture to a vertically continuous vertical track member. Each panel has a peripheral frame composed of a top member, a bottom member and a pair of side members joined at the respective corners and a facing of sheet material adhesively bonded to the frame. A seal is formed along each horizontal juncture by a horizontal gasket on the bottom frame member of the panel above the juncture that engages a flange on the top frame member of the panel below the juncture. A seal is formed at each vertical juncture by vertical gaskets on the vertical track that engage the respective side members of the panels on either side of the juncture.
