Abstract: A quick-assembly corner protector including an extruded aluminum retainer adapted to be attached to the corner to be protected; decorative wooden panels laterally, slidingly engaged in the retainer adjacent the corner; and a co-extruded vinyl locking member adapted to hold the panels in place and provide a cushion at the corner.

Abstract: A handrail-wall bumper combination which includes improved structural features for the mounting of the handrail above the bumper section, providing a common appearing design for both vinyl and wood handrail portions and accommodating, in the case of either type of handrail, a smoothly contoured gripping surface, including a well-defined and highly visible accent strip. Smooth, tangentially transitioning concave and convex surfaces are provided in front and also in back of the handrail where, although not visible to the eye, such surfaces provide improved comfort and feel and reduce skin abrasions. Improved components are also provided for assembling corners and returns, including providing slightly enlarged support surfaces for longitudinal extensions of plastic cover elements to assure optimum surface alignment at joints.

Abstract: An entrance grating for office buildings is comprised of a series of closely spaced tread rail elements, forming the upper surface of the grating, and a plurality of support elements underneath the tread rail elements and tightly secured thereto at right angles. The tread rails are of extruded construction and include a hollow, tubular spine section for high strength and rigidity per unit of weight. The underlying support elements, also of extruded construction, are in the form of downwardly opening channel-shaped elements. High strength, expandable wall, blind fasteners are employed to secure the support elements to the tread rail elements at each of the crossing points to provide a strong, rigid assembly. The open bottoms of the channel-shaped supports may be closed by plastic pad strips providing resilient support and noise reduction.
