The sleeve and collar have inwardly extending tabs to receive the adjustment screws allow adjustment of the sleeve with respect to the collar.
Claims33
An adjustable electrical box cover plate for coupling to an electrical box, said cover plate comprising:
- a base having an outer face, and an inner face, said base being adapted for coupling to said electrical box;
- a collar defining a central opening having a dimension to receive an electrical device and extending axially from said outer face of said base, said collar having at least two tabs at a bottom edge thereof extending inwardly into said central opening, said tab having an aperture therein;
- a sleeve received in said collar and being movable axially within said collar, said sleeve having at least two tabs at a bottom edge with a threaded hole therein that are aligned with a respective tab of said collar, said sleeve having a side wall with a coupling member for receiving a ground wire;
- and
- a threaded screw received in each said threaded hole of said tab of said sleeve, and said screw having an end rotatably coupled with and axially fixed with respect to said tabs of said collar, wherein rotation of said screw adjusts said sleeve axially with respect to said collar.
An electrical box cover plate comprising:
- a collar having a base for coupling to an electrical box and a side wall extending inward substantially perpendicular to said base, said base having an aperture for capturing a threaded screw to limit axial movement of said screw to said base, said collar defining a central opening;
- and
- a sleeve received in said collar, said sleeve having a bottom edge and a top edge, first and second tabs extending inward from a respective bottom edge and having a threaded aperture to receive the screw, and first and second mounting flanges extending inwardly from said top edge for mounting an electrical device.
An electrical box assembly comprising an electrical box having an open top end and an inner cavity, and an adjustable cover plate coupled to the electrical box, wherein the adjustable cover plate comprises:
- a collar having a base coupled to said electrical box, said collar having a tab extending inwardly from a bottom edge of opposite side of said collar, said tabs having an aperture for capturing a threaded screw, and
- a movable sleeve axially received in said collar, said sleeve having a bottom edge and top edge, first and second tabs extending inwardly form opposite sides of said bottom edge, said tabs having a threaded aperture to receive said screw, and first and second mounting flanges extending inwardly from said top edge for mounting an electrical device.
