Sloped ceiling adaptor
First Claim
1. An adaptor mounting plate for mounting a slope angle extension cover to a ceiling having a slope greater than 32 degrees, said extension cover having a top end to be positioned parallel to said mounting plate and a bottom end at an angle to said top end, said mounting plate comprising:
- a body,a portion of said body including a set of radial slots adapted to receive screw means for attaching said body to a junction box mounted in a recess in said ceiling so that a rotational position of said body can be easily adjusted for alignment of a pair of said slots with screw receiving holes provided on said junction box; and
a pair of deformations of said body each having a side wall portion and a bottom wall portion extending at oblique angles to the portion of said body which includes said radial slots for alignment of said bottom wall portions of said deformations parallel to said bottom end of said extension cover when said cover is mounted on said body, holes being provided through said bottom wall portions of said deformations for receiving screw means for attaching said extension cover to said body in such a manner that the mounting angle of the ceiling is reduced and the top end of the extension cover extends substantially parallel to said portion of said body including said radial slots and the bottom end of the extension cover extends substantially parallel to said bottom wall portions of said deformations.

Abstract
An adaptor assembly makes it possible to mount an electric fixture, such as a ceiling fan or electric lighting fixture, to a ceiling with a slope greater than 32°. The adaptor assembly includes a slope angle extension cover formed as a truncated conical surface with a bottom end lying in a first plane adapted for attachment to a standard fixture canopy and a top end lying in a second plane at an angle of 26° to the first plane and adapted to be attached through an adaptor mounting plate to a junction box mounted in a recess in the ceiling.
The mounting plate has a plurality of radial slots and is rotated to bring a pair of slots in alignment with screw holes in mounting lugs on the junction box for attachment with screws. The mounting plate has a pair of deformations providing flat wall portions which, when the mounting plate is installed are in parallel to the bottom end of the extension cover. A pair of screws each extend through the flat wall portion of a deformation and a screw hole provided through the bottom end of the cover to mount the cover with the top end confronting and parallel to the sloped ceiling. An insulation disk is sandwiched between the mounting plate and the ceiling and is secured to the mounting plate by a pair of adhesive tabs.

2. A slope angle extension cover comprising:
-
a circular shaped bottom end defining a planar surface including a reduced diameter opening adapted for suspending an electrical fixture below said bottom end from a ceiling having a slope of greater than 32 degrees, said bottom end lying in a first plane; an oval shaped top end for being positioned on the ceiling and extending parallel to the ceiling, said top end lying in a second plane at an angle to said first plane; and a truncated conical wall extending between said bottom and top ends.

3. An adaptor assembly for suspending an electric fixture from a junction box disposed within a ceiling having a slope greater than 32 degrees, said electric fixture having wiring which connects with a source of electricity, said adaptor assembly comprising:
-
an extension cover having a truncated conical side wall with a top edge and a bottom edge and a bottom end with an outer perimeter and an inner perimeter spaced inwardly from said bottom edge of said side wall, the inner perimeter of said bottom end and the top edge of said side wall defining openings for receiving said wiring, the bottom edge of said side wall being adjoined to the outer perimeter of said bottom end, the top edge of said side wall lying in a first plane for extending said top edge parallel to the slope of said ceiling when the extension cover is mounted below the ceiling and said bottom end lying in a second plane which is at an angle to said first plane; and a mounting plate including at least one first opening for connecting the mounting plate to the junction box and a plurality of second openings defined in wall portions extending parallel to said second plane when said extension cover is mounted on said mounting plate for adjustably connecting the mounting plate to the extension cover, said first and second openings cooperating in such a manner that the extension cover is alignable with the slope of the ceiling to reduce the mounting angle of the ceiling whereby the electric fixture is suspended from the ceiling in a substantially vertical position. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. An adaptor assembly for suspending a ceiling fan having an extension rod from a junction box disposed within a ceiling having a slope greater than 32 degrees, said ceiling fan having and wiring which connects with a source of electricity, said adaptor assembly comprising:
-
an extension cover having a side wall with a top edge and a bottom edge and a bottom end with an outer perimeter and an inner perimeter spaced inwardly from said bottom edge of said side wall, the inner perimeter of said bottom end and the top edge of said side wall defining openings for receiving said wiring, the bottom edge of said side wall being adjoined to the outer perimeter of said bottom end, the top edge of said side wall lying in a first plane for extending parallel to the slope of said ceiling when the extension cover is mounted below the ceiling and said bottom end lying in a second plane which is at an angle of 26 degrees to said first plane; a mounting plate including at least one first opening for connecting the mounting plate to the junction box and a plurality of second openings defined in wall portions extending parallel to said second plane when said extension cover is mounted on said mounting plate for adjustably connecting the mounting plate to the extension cover, said first and second openings cooperating in such a manner that the extension cover is alignable with the slope of the ceiling to reduce the mounting angle of the ceiling whereby the ceiling fan is suspended from the ceiling in a substantially vertical position; a flat insulating disk fitting within said top edge of said extension cover for mounting between the mounting plate and the junction box; and an adhesive for securing the insulating disk to the mounting plate.
