Sustainable composite materials for interior spaces and related methods of manufacture are provided. In one aspect of the invention, the sustainable composite materials include a load-bearing stud. The load-bearing stud includes a plurality of woven burlap layers impregnated with a magnesium oxide resin. The load-bearing stud is formed by creasing a woven burlap sheet to form multiple foldable panels, wetting the foldable panels with a curable resin, layering the foldable panels to achieve a multi-layered prepreg, pressing the multi-layered prepreg to distribute the resin therethrough, compacting the multi-layered prepreg within a mold cavity having the exterior shape of the load-bearing stud, and curing the multi-layered prepreg, wherein the resin includes a mixture of mono-potassium phosphate and magnesium oxide. The load-bearing stud provides a lightweight, dimensionally stable, and environmentally-friendly composite structure to replace lumber studs and metal studs in building constructions.

Sustainable composite building materials and related methods of manufacture

A floor tile for a raised floor. The floor tile is defined by a shallow upwardly-opening metal pan defining a shallow compartment in which a main preformed one-piece concrete block is secured. The main concrete block is preferably formed from a plurality of one-piece preformed concrete sub-blocks which are adhesively adhered in sideward abutting relationship to define a plan profile corresponding to the main concrete block. The main concrete block is then adhesively secured within the compartment of the metal pan.

Cover pads for use on upright walls, wherein the pad provides an improved internal support which is of simplified construction, for example the center support and the surrounding frame being made of a one-piece monolithic support structure which permits a flexible covering to be attached to the center support and the exterior side surfaces of the edge frame while the covering and support structure are in a flat and planar condition, following which the edge frame is folded and secured into position around the center support. The internal support structure for the pad, when in a flat condition, has voids at the corners so that the covering can be tucked into the corners prior to the edge frame being folded into its frame-defining position.

Pad for wall panel and forming process

A cover pad for an upright wall having an improved support for simplifying attachment of a flexible covering such as fabric. The support includes a flat substrate sized to closely conform to the assembled cover pad. A ringlike frame defined by frame elements extend along edges of the substrate. Each frame element has a first elongate part engaged with the respective edge of the substrate, and a second elongate part joined to the first part by a lengthwise hinge. The second part functions as a hinging flange which is initially in an open position generally aligned with a front face of the substrate so that a flexible covering can be secured, as by adhesive, to an exposed surface of the flange while maintaining the fabric positioned across the face of the substrate. The hinging flanges of the frame elements are folded inwardly to overlie respective edges of the substrate, thereby securing the fabric across the face of the substrate and wrapped around the edges thereof.

Covered pad for wall panel and manufacturing process

Cover pads for use on upright walls, wherein the pad provides an improved internal support which is of simplified construction, for example the center support and the surrounding frame being made of a one-piece monolithic support structure which permits a flexible covering or fabric to be attached to the center support and the exterior side surfaces of the edge frame while the fabric and support structure are in a flat and planar condition, following which the edge frame is folded and secured into position around the center support. The internal support structure for the pad, when in a flat condition, has voids at the corners so that the fabric can be easily tucked into the corners prior to the edge frame being folded into its closing or frame-defining position.

Method of forming a fabric covered pad for wall panel

An instruction card assembly which includes a spacer plate and a card including printed or pictorial instructional information thereon. The spacer plate is sandwiched between the underside of a worksurface and an elongate track utilized for slidably mounting an arm assembly of a keyboard pad arrangement such that a sidewardly opening recess is defined. The card is disposed in this recess and is slidably movable between a retracted storage position wherein the card is positioned substantially beneath the worksurface and an extended use position for displaying operational instructions for reference by a user.
