Abstract
This invention pertains to an adjustable cover for an electrical outlet box.
The cover is configured having a generally planar mounting plate with a collar surrounding an opening through this mounting plate. An extension sleeve moves within this opening and adjacent the collar. At least one fastener is located adjacent the opening and is movable between a locked position and an unlocked position. The fastener operates a locking device that engages wedges against the extension sleeve when the fastener is in the locked position and disengages wedges against the extension sleeve when the fastener is in the unlocked position.
The cover is configured having a generally planar mounting plate with a collar surrounding an opening through this mounting plate. An extension sleeve moves within this opening and adjacent the collar. At least one fastener is located adjacent the opening and is movable between a locked position and an unlocked position. The fastener operates a locking device that engages wedges against the extension sleeve when the fastener is in the locked position and disengages wedges against the extension sleeve when the fastener is in the unlocked position.
Claims (20)
1. An adjustable cover for an electrical outlet box comprising:
(a) a mounting plate having a collar surrounding an opening, said collar having a distal end region remote from said mounting plate, said distal end region including at least one tab protruding into said opening;
(b) an extension sleeve sized to move within said opening adjacent said distal end of said collar;
(c) at least one fastener extending through said tab and movable between a locking and an unlocking position; and (d) at least one locking device operable by said fastener, each of said at least one locking device includes a pair of L-shaped wedges configured to selectively engage and disengage said extension sleeve so as to selectively lock and unlock said extension sleeve with respect to said mounting plate.
(a) a mounting plate having a collar surrounding an opening, said collar having a distal end region remote from said mounting plate, said distal end region including at least one tab protruding into said opening;
(b) an extension sleeve sized to move within said opening adjacent said distal end of said collar;
(c) at least one fastener extending through said tab and movable between a locking and an unlocking position; and (d) at least one locking device operable by said fastener, each of said at least one locking device includes a pair of L-shaped wedges configured to selectively engage and disengage said extension sleeve so as to selectively lock and unlock said extension sleeve with respect to said mounting plate.
2. The adjustable cover as set forth in Claim 1 wherein a first said fastener and a first of said at least one locking device is located through a first said tab, and a second said fastener and a second of said at least one locking device is located through an opposing tab.
3. The adjustable cover as set forth in Claim 1 wherein said fastener extends through said wedge.
4. The adjustable cover as set forth in Claim 3 wherein said at least one tab includes an interior threaded aperture.
5. The adjustable cover as set forth in Claim 4 wherein said wedge is sandwiched between said at least one tab and a head of said fastener.
6. The adjustable cover as set forth in Claim 5 wherein said extension sleeve is configured with mating surfaces for engagement thereof by said wedge.
7. The adjustable cover as set forth in Claim 6 wherein said configuration is a concaved channel extending along a sidewall of said extension sleeve.
8. The adjustable cover as set forth in Claim 1 wherein said pair of wedges are identical and seat upon each other.
9. The adjustable cover as set forth in Claim 8 wherein said each of said wedges includes an upper surface extending between two L-shaped surfaces, each of said upper surfaces are in contact with each other.
10. The adjustable cover as set forth in Claim 9 wherein said upper surface includes a pair of parallel planar surfaces connected to each other by a first angled surface.
11. The adjustable cover as set forth in Claim 10 wherein said wherein said upper surface includes a second angled surface.
12. The adjustable cover as set forth in Claim 11 wherein said second angled surface is smaller than said first angled surface.
13. The adjustable cover as set forth in Claim 12 wherein one of said pair of planar surfaces is smaller than another of said pair of planar surfaces.
14. The adjustable cover as set forth in Claim 13 wherein said first angled surface is parallel to said second angled surface.
15. The adjustable cover as set forth in Claim 1 wherein said fastener includes an end which is larger then an aperture in said tab to prevent said fastener from being removable from said aperture.
16. An adjustable cover for an electrical outlet box comprising:
(a) a mounting plate having an inner rim, said inner rim defining an opening, said inner rim including two opposing tabs on opposite sides of said inner rim and protruding into said opening ;
(b) an extension sleeve extending adjacent to said inner rim and said opening, said extension sleeve extending generally perpendicular to said mounting plate, said extension sleeve being freely movable within said inner rim;
(c) two locking devices, each device including a fastener and a pair of L-shaped wedges, each fastener extending through each of said pair of L-shaped wedges and one of said two tabs, said locking devices configured to selectively engage and disengage said extension sleeve so as to selectively lock and unlock said extension sleeve with respect to said mounting plate.
(a) a mounting plate having an inner rim, said inner rim defining an opening, said inner rim including two opposing tabs on opposite sides of said inner rim and protruding into said opening ;
(b) an extension sleeve extending adjacent to said inner rim and said opening, said extension sleeve extending generally perpendicular to said mounting plate, said extension sleeve being freely movable within said inner rim;
(c) two locking devices, each device including a fastener and a pair of L-shaped wedges, each fastener extending through each of said pair of L-shaped wedges and one of said two tabs, said locking devices configured to selectively engage and disengage said extension sleeve so as to selectively lock and unlock said extension sleeve with respect to said mounting plate.
17. The adjustable cover as set forth in Claim 16 wherein each of said pair of wedges is sandwiched between said mounting plate and a head of said fastener.
18. The adjustable cover as set forth in Claim 17 wherein said extension sleeve is configured with mating surfaces for engagement thereof by said pair of wedge.
19. The adjustable cover as set forth in Claim 16 wherein said each of said wedges includes an upper surface extending between two L-shaped surfaces, each of said upper surfaces are in contact with each other.
20. The adjustable cover as set forth in Claim 19 wherein said upper surface includes a pair of parallel planar surfaces connected to each other by a first angled surface.
