A corner structure is provided for impact-resisting handrail installations. The design of the structure is such that the same principal components may be employed in constructing outside corners, inside corners and returns. The corner structure includes a molded tubular shell of arcuate configuration, for connection to each of two right angularly related straight handrail sections or from one handrail to an adjacent wall. An internal skeletal support member is mounted within the hollow tubular shell, by closure panels secured to and closing the opposite ends of the shell. The skeletal support member includes an arcuate central portion arranged in confronting and supporting relation to the outwardly facing wall of the shell. Connecting elements project outward through each of the closure panels for rigid connection to the adjacent straight handrail sections. By substitution of two different internal skeletal supports, the corner structure can be configured for inside and outside corners. The skeletal supports themselves are adapted to be inexpensively produced by extrusion processes. Substantial savings in manufacturing costs are realized.

Corner/return construction for impact-resistant handrails

A resiliently mounted and constructed rigid floor grate assembly is disclosed, in which a series of metallic tread rails of T-shaped cross section, placed side by side and connected by tie rods, are separated by individual, resilient spacing and supporting elements. The spacing and support elements are placed between each pair of tread rails, underneath the tread portions thereof, and are held under compression by the tie rods to form a rigid assembly. In addition, the height of the spacing and support elements is slightly greater than the height of the vertical web portions of the tread rails, to support the metallic elements slightly above the hard surface of a floor recess in which the grate assembly is placed. Significantly reduced metallic noise and clatter is an important benefit.

Resiliently mounted rigid floor grating

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. Adjacent slot-like sections are secured tightly together either by way of the tongue and groove structure, or by separate means.

Rigid grating mat with unidirectional elements

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.
