Abstract: An assembly includes a bracket mountable directly to a wall. An inner periphery of the bracket defines an opening in the wall substrate. A resilient element, cantilevered from an outer side surface of the sleeve, is retained by a barbed element at the inner periphery of the bracket.

Abstract: A plug housing includes an ejector mechanism and a controller electrically coupled to the ejector mechanism for detaching electrical conductive blades of the plug from a mated connection with a female connector. In response to a switch signal from the controller, a solenoid is activated to release a latch in the mechanism, thereby permitting the force of a compressed spring to impel a structure outwardly from the plug. The controller may be located remotely from the plug and superimpose control signals to the plug over the power lines within the cord.

Abstract: An assembly includes a box and a removable sleeve that is engageble with the box and with a wall substrate to secure tight contact between the wall substrate and the box structure, irrespective of the thickness of the wall substrate. The sleeve is configured to be coupled to an electrical device having a corresponding configuration for insertion in the box.

Abstract: A ceiling support system includes a bracket mechanism that can be attached to ceiling joists. An upwardly extending flange arrangement provides support for a ceiling fixture while allowing adjustment of its position before being secured to the support system. The flange arrangement may be flexible and secured to the ceiling structure via resilient hangers.

Abstract: An assembly includes a bracket mountable directly to a wall. An inner periphery of the bracket defines an opening in the wall substrate. A removable sleeve is engageable with the bracket and the wall substrate to secure tight contact between the wall substrate and a device interior of the wall, irrespective of the thickness of the wall substrate. A resilient element, cantilevered from an outer side surface of the sleeve, is retained by a barbed element at the inner periphery of the bracket.

Abstract: A self-supporting apparatus can be placed in an opening in an existing wall substrate. A frame assembly is configured with a perimeter that can be adjusted to correspond to the opening of the wall substrate. Opposing frame portions are movable in opposite directions with respect to each other to be expandable for contact with the opening. Each frame portion comprises a first side having a detent on one surface and a second side with at least one groove on a surface thereof. The surfaces of the opposing frame portions face each other. The detents and grooves are dimensioned to provide engagement, respectively, between grooves and dents of facing frame portion surfaces.

Abstract: A self-supporting apparatus can be placed in a pre-set opening in an existing wall substrate. A frame assembly is configured with a perimeter that corresponds to the thickness of the wall substrate. The edge of the frame thus can be in fitting contact with the substrate opening. Flanges on opposite sides of the frame extend in the planar direction of the wall substrate to be in contact with the inner and outer surfaces of the substrate to maintain the frame in position in the wall and to strengthen the structure. The frame can include appropriate mounting portions for mounting electrical boxes or low voltage devices within the wall.

Abstract: An opening in a vapor barrier membrane interior to a ceiling can be sealed by a flexible enclosure. A planar member of the enclosure can be bonded to the inner side of the membrane. The enclosure is formed with a cavity that can encompass a ceiling mounted electrical device. A fastener is joined to the planar member permits bonding thereof with an interior surface of the membrane by manual application of a compressive force. The fastener may comprise a removable release liner covering an adhesive.

Abstract: A bracket assembly includes first and second frame portions movable with respect to each other between a retracted bracket position to an expanded bracket position for contact with opposing portions of a perimeter of an opening in an existing building wall substrate. A flange extends in a planar direction from each frame portion for contact with an outer surface of the wall substrate. A resilient retainer is spaced on the frame from the flange member by a thickness of the wall substrate. The retainer exerts a compressive force on an inner surface of the wall substrate when the bracket assembly is moved to its expanded position.

Abstract: An electrical device support assembly that includes a bracket member that can be mounted on a building wall stud during new construction, and a frame, external to the wall substrate, that is engageable with the bracket member through an opening in the wall substrate. The bracket member may have a plurality of flange elements extending from the perimeter edge of the opening in an internal direction from the wall substrate.

Abstract: A ceiling fixture support arm includes a rotational mechanism for interfacing the arm with ceiling support system structure. An extended member of the support arm and a member perpendicular thereto may include a rotational mechanism integral thereto as a hinged portion, or tab, thereof. One or more channels of the ceiling support structure may contain a plurality of flexible sections spaced at intervals along the length of two upper flanges that are separated by a channel width. Each section comprises a cantilevered tab formed in the flange material.
