Abstract: A reinforced material includes a foam layer that has a first side. A pre-stretched laminated oriented mesh fabric is fused to at least a portion of the first side. In a method of making a reinforced material, a pre-stretched laminated oriented mesh fabric is applied to a first side of a foam layer. The pre-stretched laminated oriented mesh fabric is fused to the first side of the foam layer until the pre-stretched laminated oriented mesh fabric becomes bonded to the first side.

Abstract: A folding table has a leg pivotally coupled to a bottom of a tabletop. A pair of links is pivotally coupled together and pivotally coupled in series between the tabletop and the leg. The pair of links, the tabletop and the leg form a four-bar, four-pivot linkage, including four pivots and four bars defined between the pivots. The bars of the linkage are sized and the pivots of the linkage are located to resist movement of the linkage through an intermediate binding configuration between open and closed configurations.

Abstract: A uniquely designed torque wrench having a torque body, the torque body attached to a drive head, the drive head entering a contracted stated during extension of a rod of a hydraulic cylinder, and entering an expanded state during the retraction of the rod of a hydraulic cylinder.

Abstract: A closure strip, for use with a corrugated material, includes an elongated flat thermoplastic sheet member and a plurality of thermoplastic undulations. The elongated flat thermoplastic sheet member has a bottom surface and an opposite top surface. The elongated flat thermoplastic sheet member defines a plurality of linearly disposed and spaced apart openings therethrough. A plurality of thermoplastic undulations is complimentary in shape to the corrugated material. Each undulation extends upwardly from the flat thermoplastic sheet member and defines a void that opens to a different one of the openings defined by the flat thermoplastic sheet member.

Abstract: A folding or stacking chair has a seat and a backrest carried between opposite frame sides each with a backrest support, a front leg and a rear leg. One or both of the seat and the backrest has a continuous sheet of flexible and elastic knitted mesh or patterned open texture plastic held across and substantially covering an opening in an open-end hoop coupled between the frame sides. An open-end of the hoop faces in a front or a back orientation for the seat, or a top or a bottom orientation for the backrest, with sides of the hoop attached to the frame sides. The sheet of mesh or textured plastic has a finished edge spanning the open-end of the hoop.

Abstract: An adjustable door sweep with an upper frame, a lower carrier, and at least one brush is provided. The adjustable door sweep includes diagonally oriented slots in the walls of the upper frame and the lower carrier with attached rotatable rods to assist in vertical adjustment of the extensions, such as brushes. The method of using such an adjustable door sweep is also provided.

Abstract: A clamping joint for a chair includes a joint coupling a front leg and a rear leg to the seat at an overlap with an inner clamp coupled to the seat and an outer clamp coupled to the inner clamp with the front leg and the rear leg clamped between the inner and outer clamps at the overlap. A finger on one of the inner or outer clamps extends towards the other and disposed between the front and rear legs.

Abstract: A stackable chair has a seat and a backrest carried between opposite frame sides each with a backrest support, a front leg and a rear leg. One or both of the seat and the backrest have a continuous sheet of flexible and elastic mesh or patterned open texture plastic held across and substantially covering an opening in an all-plastic hoop fixed between the frame sides.

Abstract: A light-weight, folding table has a plurality of folding legs coupled to a table top. The table top includes a laminate with a plastic sheet bonded to a plywood layer. A perimeter edge channel encloses a perimeter edge of the laminate along the sides without enclosing corners of the laminate. Corner caps cover the corners of the laminate. The corner caps overlap ends of the edge channel at the corner.

Abstract: A shielding material includes a non-conductive sheet, an elongated adhesive strip and a conductive sheet. The elongated adhesive strip is disposed on a first side of the non-conductive sheet. The adhesive strip is spaced apart from a first edge of the non-conductive sheet and includes a removable cover film that protects the elongated adhesive strip until it has been removed. The conductive sheet is adhered to a second side of the non-conductive sheet. A first end of the conductive sheet is spaced apart from the first edge of the non-conductive sheet so that a first portion of the conductive sheet extends beyond the first edge of the non-conductive sheet. The conductive sheet is also disposed relative to the non-conductive sheet so that the second end is parallel to a second edge and so that a second portion of the non-conductive sheet extends beyond the second end.

Abstract: An underlayment material includes a sheet of masticated rubber. A vapor barrier film is extruded onto the sheet of masticated rubber. In one embodiment, a portion of the vapor barrier film extends beyond at least one edge of the sheet of masticated rubber so as to form a flap extending therefrom. An elongated adhesive strip is disposed on a first side of the vapor barrier film. The elongated adhesive strip includes a removable cover film that protects the elongated adhesive strip until the cover film has been removed. The elongated adhesive strip is positioned so as to facilitate sealing of the flap extending from the vapor barrier film of a first unit of the underlayment material to the elongated adhesive strip of a second unit of the underlayment material.

Abstract: A folding mesh chair includes a seat and a backrest carried between opposite frame sides. The chair has an unfolded seating position in which the seat pivots to extend from the frame sides and bottoms of front and rear legs move apart, and a folded position in which the seat pivots toward the frame sides and the front and rear legs move together. One or both of the seat and the backrest have a continuous sheet of flexible and elastic mesh or patterned open texture plastic held across and substantially covering an opening in an all-plastic hoop fixed between the frame sides. The hoop includes inner and outer plastic mating hoops with the mesh extending over an outer perimeter of the inner hoop and into an interface between the inner and outer hoops.
