Abstract: A door is constructed with a separate member joined to the door edge by a tongue-and-groove coupling and screws so as to be readily removable and replaceable. The separate member sustains the impacts imparted to the door by carts or wagons pushed past the door and can be readily replaced when damaged, thus avoiding replacement of the entire door. A flexible cover snaps over the outer surface of the separate member to add impact resistance and aesthetic appeal. Intumescent strips may be inserted inside or outside of the cover to enhance sealing between the door, and as adjacent door or door frame, thereby improving the fire resistance rating of the door. Accent strips or reveals of contrasting or complementary colors may be incorporated to add to the aesthetic appeal of the door. The door construction is of particular utility in schools, health care facilities and other institutions.

Abstract: A rail has an axially extending undercut groove of a uniform generally “C” shape in cross section and is supported by supports attached to the rail in spaced-apart relation. Each support includes a bracket and a lock member attached to the bracket for rotation and against displacement of the lock member relative to the bracket member. The lock member includes a locking cam portion, which is received in the undercut groove and has a size and shape such that it can enter the undercut groove when it is in an unlocked rotational position relative to the undercut groove and such that it frictionally engages walls of the undercut groove in a locked rotational position relative to the undercut groove and thereby retains the rail against displacement relative to a structure that supports the rail.

Abstract: A foot mat has a plurality of elongated rail members (20) arranged closely adjacent each other with a gap between each adjacent pair of rail members. Each rail member is of uniform cross section along its length and includes a body portion (22) and a pair of spaced-apart dependent leg portions (27). An elongated tread member (100, 104, 106, 108 or 110) is received on the upper surface of each rail member. Each adjacent pair of rail members is joined by an extruded plastic connector member (30) that has a connecting web portion (32) and a pair of generally U-shaped socket portions (38). Each leg portion of each rail and each socket portion of each connecting member are configured to snap-fit together and have interengaging shoulders (27s and 38s) that are configured to retain the leg portion in the socket portion.

Abstract: A panel wall system is based on panels, each of which includes a sheet of high density fiberboard, a vapor barrier on the back surface of the fiberboard sheet and a sheet of substantially rigid polymeric material adhesively secured to the front face of the fiberboard sheet, the polymeric sheet having a thickness of not less than about 0.022 inch. The other components of the system are various trims and moldings.

Abstract: A panel wall assembly comprises rectangular pan-like panels mounted close together side by side and end to end. Retainers located at all junctures between the panels are fastened to the building structure, and the panels are fastened to the retainers by clips having arms that extend out through slots in the panel flanges. Troughs on each horizontal retainer drain condensate or water that leaks through seals between adjacent panels to drainage slots in the vertical retainers. Gaskets between the retainers and the panel flanges provide additional control of water flow behind the panel faces.

Abstract: A device for affixing two panels in abutting relationship to a support structure including an elongated base member with two transversely spaced, elongated areas each defining a planar surface for engaging the underside of the panels, an elongated locking projection integral with and extending from the base member with a height greater than the thickness of the panels, and areas for receiving fasteners to secure the base member to the support structure. The device also includes an elongated cap with an integral, elongated slot for engaging the locking projection and elongated panel contacting areas on each side of the slot for contacting the upper surface of the panels.

Abstract: A handrail and crash rail comprises a rigid retainer and a cover of a resilient, impact-resistant plastic mounted on the retainer by means of upper and lower flanges on the cover which engage and are held on corresponding flanges on the retainer. Clearances are left between the impact wall of the cover and the front surfaces of the retainer flanges so that the cover can deflect inwardly toward the retainer upon impact. At least one longitudinally extending, resiliently compressible cushion mounted on the retainer between the retainer flanges engages the impact wall of the cover to control the extent of deflection of the cover upon impact, absorb some of the energy of the impact, and restore the cover to its initial position after impact. Additional cushions can be included. Special internal and external corner assemblies and an end assembly are used with rail sections to form a complete rail system.

Abstract: A crash rail for mounting on a wall or the like to absorb impacts comprises mounting clips fastened at intervals to the wall, an elongated crash member of a resilient, impact-resistant polymeric material fastened to the clips, and an elongated structural back-up member mounted on the clips between the front wall of the crash member and the wall. A longitudinally continuous impact cushion is interposed between the structural back-up member and the inner face of the front wall of the crash member and permits deformation of the front wall of the crash member, but limits the degree of such deformation, and absorbs part of the energy of an impact to the crash member.

Abstract: A floor mat comprises substantially rigid, elongated rails disposed generally parallel to each other in closely spaced relation. Each rail has a base portion for supporting the mat and a top portion with a tread surface such as a strip of carpet, abrasive or vinyl thereon. Cooperative ball and socket structures along opposite sides of the rails fixedly space the rails from each other but permit rotational movement of the rails relative to each other whereby the floor mat may be rolled up or adjust itself to irregular floor surfaces.
