Abstract: An electrical wiring box with outer dimensions specifically sized and shaped to match a standard architectural component is disclosed. The disclosed electrical wiring box is of a minimum size corresponding to industrial standards and configured to accept standard electrical wires and fittings. The outer dimensions of the disclosed electrical wiring box are selectively larger than the standard box. The invention discloses an electrical wiring box which is the size of a standard fired clay building brick, or fraction thereof, thus simplifying installation in a wall of brick and mortar construction. The invention further discloses a cover which simulates a brick surface thus providing for improved appearance when installed in a brick wall. The electrical wiring box disclosed in this invention can take a number of different configurations and be used in different orientations to provide simplified installation and improved aesthetics.

Abstract: A wall outlet box for a dryer exhaust conduit. The box includes a plurality of substantially planar integral walls defining an enclosure open at the front thereof. The enclosure includes a back surface, a pair of opposing side surfaces, a top surface, and a bottom surface. The opposing side surfaces, back surface and top surface include forward facing edges collectively defining a front periphery. The front periphery preferably has a perimeter greater than the perimeter of the back surface. The bottom surface preferably extends downwardly from the back surface to the front periphery. The wall outlet box further includes at least one port in the enclosure adapted to engage with a dryer exhaust conduit. A mounting lip, which can include mounting structures, extends outwardly from the forward facing edges. The mounting lip can be configured in an L-shape to provide a shoulder which abuts the edges of a wall surface.

Abstract: A fastening assembly is constituted by a plate-like member provided with a plurality of laterally extending projections which can be pushed into position between and then turned into engagement with respective slots formed in protrusions. In one aspect, at least one of the projections and/or at least one of the slots is adapted to give a wedging effect. In another aspect, the protrusions are located around an inner periphery of otherwise circular outline presented by a hollow member, and the projections are formed as arcuate sectors located around the plate-like member which presents an outer periphery of circular outline other than at recesses for receiving the respective protrusions.

Abstract: A box, in particular for electrical devices, is built into a wall of any kind by fitting into an opening therein. The box includes a transverse flange which bears in the manner of a guard against the wall to be equipped and, beyond the flange, at least one elastically deformable lug projecting laterally to cooperate with the wall. The elastically deformable lug has two branches with a common root and extending in respective different directions, namely, referred to the insertion direction, a first or front branch extending globally away from the flange and a second or rear branch extending globally towards the flange. Applications include electrical devices, for example infrared radiation receiving cells.

Abstract: A generally planar electrical box mounting bracket is securable to a convenient wall stud and is supported by a wall spacer. The bracket defines an aperture and a pair of countersunk recesses diagonally positioned with respect to the aperture. A pair of flushmounting fasteners are received within the countersunk recesses and threadably engaged the tabs of an electrical box to secure the electrical box against the interior or rear face of the bracket. A second pair of fasteners are positioned diagonally at opposite corners with respect to the center aperture and are used to secure an electrical box ring upon the front face of the bracket. The attachment of the electrical box ring is independent of the attachment of the electrical box to the bracket thereby facilitating the removal and assembly of the electrical box ring to the bracket without disturbing the attachment of electrical box.

Abstract: A double divisible connector frame for use as a support member for mounting return grilles and louvers in a building structure which is rectangular in shape and having a planar surface on one side and a pair of precisely-similar spaced-apart continuous rectangular flanged frames on the other side, and a lineal line of severance equidistant between said smaller flanged frames for dividing said double frame into a pair of similar smaller frames for mounting said grilles and louvers.

Abstract: A foldable, electrical box kit for on-site assembly and installation in wallboard, with at least two opposing panels each having a pair of spaced apart front face flanges and respective, laterally centered on the panel, center-bored, retaining screw and rotating retainer clip assemblies. The unfolded box is configured with living hinge lines to permit easy folding and snap assembly of adjacent sidewall edges to form a rigid enclosure. Retainer clips are retracted by their retaining screws into clip slots in the panels for clearance. The box is inserted through wallboard as far as the front face flanges permit, then the retaining screws are rotated, the first quarter turn of which rotates their respective retaining clips from the retracted position to an extended position behind the wallboard. Further clockwise rotation of each screw brings its retaining clip forward into a firm, three point grip with its respective pair of flanges on the wallboard.
