Abstract
Abstract A rotatable floor receptacle mounting unit is provided that includes an electrical receptacle mount that is pivotally supported within an opening in a mounting ring so that electrical receptacles thereon can be rotated to either an exposed position or a concealed position in a recess in the floor. An adjustable seal ring is coupled to form the upper annular surface of the mounting ring. When the seal ring is fastened to the mounting ring flush with the level of the floor, the inner peripheral surface thereof overlaps an annular shoulder formed on the periphery of the mount to enable a sealing gasket to be compressingly engaged therebetween. When it is desired to flip over the receptacle mount the seal ring is released and raised to provide sufficient clearance for enabling the mount to be swung on its pivotal support past the inner peripheral surface of the seal ring. The seal ring is then again lowered and fastened flush with the level of the floor to seal the mount in its new position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
A rotatable floor receptacle mounting unit comprising a mounting ring, an electrical receptacle, a mount for said electrical receptacle, said mount pivotally supported in said mounting ring so that it can be rotated to a position in which the receptacle thereon is exposed for use above the level of the floor or to a position in which the receptacle is concealed below the level of the floor, said mount having an outer peripheral surface, a seal ring forming the upper annular surface of said mounting ring, said seal ring being releasably coupled to said mounting ring such that it is either in a lowered position flush with the level of the floor or in a raised position above the level of the floor, a resilient means, said seal ring having an inner peripheral surface for compressingly engaging said resilient means against the outer peripheral surface of said mOunt when said seal ring is flush with the level of the floor, and means for releasing said seal ring to permit it to be moved to its raised position to enable said mount to be rotated about its pivotal support in said mounting ring from one said position to the other said position.
Claim 2
Dependent Claim
201 words
A rotatable floor receptacle mounting unit comprising a mounting ring, an electrical receptacle, a mount for said electrical receptacle, said mount pivotally supported in said mounting ring so that it can be rotated to a position in which the receptacle thereon is exposed for use above the level of the floor or to a position in which the receptacle is concealed below the level of the floor, said mount having an outer peripheral surface, a seal ring forming the upper annular surface of said mounting ring, said seal ring being releasably coupled to said mounting ring such that it is either in a lowered position flush with the level of the floor or in a raised position above the level of the floor, a resilient means, said seal ring having an inner peripheral surface for compressingly engaging said resilient means against the outer peripheral surface of said mOunt when said seal ring is flush with the level of the floor, and means for releasing said seal ring to permit it to be moved to its raised position to enable said mount to be rotated about its pivotal support in said mounting ring from one said position to the other said position.
Claim 3
Dependent Claim
15 words
The invention in accordance with claim 1 wherein said resilient means is a sealing gasket.
Claim 4
Dependent Claim
35 words
The invention in accordance with claim 2 wherein said seal ring is provided with fasteners for fastening said seal ring to said mounting ring in said lowered position flush with the level of the floor.
Claim 5
Dependent Claim
41 words
The invention in accordance with claim 3 wherein said means for releasing said seal ring includes springs on the undersurface thereof for raising said seal ring to a raised position above the level of the floor when said fasteners are unfastened.
Claim 6
Dependent Claim
64 words
The invention in accordance with claim 4 wherein said seal ring is provided with pins on the undersurface thereof, wherein said mounting ring is provided with an inner flange having openings therein for receiving said pins, and wherein said springs are positioned on said pins so as to bear against the underside of said seal ring and the inner flange of said mounting ring.
Claim 7
Dependent Claim
61 words
The invention in accordance with claim 3 wherein said fasteners extend through openings in said seal ring to locks on the inner flange of the mounting ring, and whereby upon said seal ring being pressed down against said springs, said fasteners can be rotated to lock said seal ring in the said lowered position flush with the level of the floor.
Claim 8
Dependent Claim
49 words
The invention in accordance with claim 2 including an additional sealing gasket, said additional sealing gasket being compressingly engaged between the outer lower surface of said seal ring and the upper surface of said mounting ring when said seal ring is positioned flush with the level of the floor.
Claim 9
Dependent Claim
51 words
The invention in accordance with claim 7 including an outer casing for said mounting ring, and a third sealing gasket, said mounting ring being secured to said casing to compressingly engage said third sealing gasket between the lower surface of said mounting ring and the lower inside surface of said casing.
Claim 10
Dependent Claim
103 words
The invention in accordance with claim 1 wherein said mount is in the form of a cylindrical disc with the receptacle mounted on one face thereof, and wherein the outer peripheral surface of said mount comprises an annular shoulder adjacent each of the faces of the disc, and wherein said seal ring has a central opening in which either face of said mount can be closely fitted when the seal ring is in a lowered position such that the adjoining surfaces of the seal ring and the face of the mount are flush with each other and with the level of the floor.
