Abstract: A collapsible building element of sheet material comprising four prismatic sides hingedly connected to each other, each side comprising two faces in V-shaped relationship and interconnected by a hinge structure, two adjacent sides having an outwardly extending V-shape, but other adjacent sides having an inwardly extending V-shape.

Abstract: A laminated building panel of the type comprising a metal facing sheet and a backing. The backing is pre-notched and/or cut in the factory to permit field-bending of the panel to produce corner structures. A factory installed splice plate is secured to the building panel to maintain the structural integrity of the panel during handling and shipment to the job site. A method for preparing the panel for shipment to an erection site is described.

Abstract: A process for making an adjustable split door frame is disclosed, the process comprising the steps of cladding the front surface of the board with vinyl, grooving a plurality of parallel grooves of various shapes in the back surface of the board down to but not through the vinyl, folding and gluing the board along the grooves, inserting a support member and attaching a hard board to the back surface of the resulting door frame. In addition, a second board is clad, grooved and folded in a similar manner to provide the other half of the split adjustable door frame.

Abstract: A refrigeration apparatus enclosure and method of forming the same wherein an inner laminate wall is provided in an outer cabinet for providing the sheet liner and insulation portions of the refrigeration apparatus enclosure. The laminate wall is folded along lines cut through the insulation to conform to the configuration of the outer cabinet and insulation is provided for filling the resultant voids to complete the enclosure construction. The voids are filled by foamed-in-place plastic which may further serve to bond the laminate wall to the outer cabinet. The rear wall of the cabinet may comprise a flat laminate wall and a divider wall may be provided within the cabinet for dividing the space therein into separate compartments. The divider wall may comprise another laminate wall.

Abstract: An imitated jalousie door or shutter including a frame having a jalousie block mounted therein and a method of making such a door. The jalousie block is constructed from a base plate of relatively non-bendable material having a thin bendable foil bonded to the front and back surfaces of the plate. A plurality of parallel V-shaped slots are cut in the front and back surface of the plate through one layer of foil and completely through the thickness of the plate but not through the second layer of foil. The block may then be folded in a zigzag or jalousied relation to be received and secured by the frame. A similar method is provided for forming the frame.

Abstract: A sandwich panel multi-sided structure mountable on a vehicle body, as a pick-up truck or trailer. The structure is formed from a single flat sandwich panel comprising a bendable sheet metal facing and a rigid plywood facing bonded to opposite sides of a plastic foam core. The core is a compressible expanded polystyrene foam. The panel is provided with spaced pairs of transverse grooves extended through the rigid plywood facing toward the bendable metal facing. The grooves are along the corner sections and divide the panel into a roof section and opposite side sections. The side sections have openings for receiving window structures. The structure is formed by bending the sheet metal facing and compressing the core along the corner sections to form a roof converging outwardly and downwardly from a longitudinal ridge and upright side walls. The back of the pick-up cover is closed with an end wall having a door.

Abstract: The invention relates to the manufacture of cementitious board, such as gypsum board, faced with paper or other sheets and having an improved accuracy of edge profile. A sheet to be folded at the lateral edges of the board is scored, and quick-setting adhesive, preferably a hot melt adhesive, is applied along the lines of folding. The sheet is then folded to the desired configuration and held until the adhesive has set thus establishing an accurate profile that withstands the action of the aqueous slurry of cementitious material and the application of the other sheet. The invention can be applied to various profiles, including square edge, tapered edge, rebated and tongue-and-groove.

Abstract: An insulating blanket is disclosed in which a semi-rigid mat of glass fibers is bonded on one side to a facing material. Lateral cuts are formed in the mat extending from the opposite side thereof toward the side on which the facing is bonded. Such cuts allow the facing to bend with a hinge-like manner when the insulating blanket is rolled, permitting the lamination of the facing and mat and the rolling of the laminate prior to the setting of the adhesive. The preferred method and apparatus for forming such insulating blanket is also disclosed.

Abstract: Improved forming method permits a flat laminate panel comprising a thin, deep vacuum formed thermoplastic face surface member bonded to a rigid backing member to be bent sharply so as to form the sides and front of a cabinet, for example, in one integral piece. The bends are accommodated by removing material from the back of the panel so as to form V-grooves whose included angles are equal to the angle of bends desired. The grooves extend through the entire thickness of the backing member and a portion of the plastic layer. A small bead of hot melt adhesive placed in the groove serves to soften the plastic so it can be bent without cracking. The panel sections adjacent the V-grooves are then brought into contact and immediately and permanently bonded together by the adhesive, thus eliminating the need for additional bracing while the adhesive sets.

Abstract: The baseboard arrangement includes a fairing unit, which is used in conjunction with a baseboard member of the type comprised of a flat foot portion adapted to lie flat against a floor surface and a vertical wall-facing portion adapted to lie flat against the meeting wall surfaces of a projecting corner of a room or corridor, for example. The flat foot portion of the baseboard member is slitted in direction transverse to the elongation of the baseboard member, with the slit terminating at the vertical wall-facing portion of the baseboard member. Accordingly, the baseboard member, at the region of such slit, can be bent around the projecting corner, thereby causing the slit to spread and form a larger corner gap. The fairing unit includes two flat leg portions adapted to lie flat against the floor surface along the meeting walls of the projecting corner, underneath part of the foot portion of the baseboard member, and these leg portions enclose a substantially right angle.

Abstract: A trim strip of U-section for a marginal edge of an automotive body panel or the like comprises a flexible but relatively stiff core member of U-section formed of metal and having a plurality of longitudinally spaced transverse slots to permit the strip to deform in conformance to the contour of the panel edge. A flexible plastic decorative covering is secured to the core in overlying relation but is outspaced therefrom except along oppositely spaced marginal edges. In a modification a core member of wire mesh is used.

Abstract: A refrigeration apparatus enclosure structure wherein an inner laminate wall portion of the enclosure defines the inner sheet liner and insulation disposed within an outer cabinet portion of the enclosure and is secured to a portion of the cabinet wall with the sheet liner portion maintained spaced from the cabinet wall to provide thermal insulation therebetween. The laminate wall is secured to the cabinet by insulative support means extending through openings in the insulation to the sheet liner and means are provided for securing the sheet liner to the inner end of the insulative supports. The insulating supports may further support other elements within the enclosure inwardly of the sheet liner.
