Fixture housing using dog ears
First Claim
1. A fixture housing with dog ears comprising:
- a planar supporting surface;
said planar supporting surface having an opening;
said planar supporting surface having a plurality of tubes extending perpendicular to said planar supporting surface on a first side of said planar supporting surface;
each of said plurality of tubes having a central shaft having a square cross-section, a spring and a slider;
said slider having a square central opening whereby said slide is keyed to said central shaft whereby rotation of said central shaft rotates said slider;
said slider has an ear that extends outside of said tube;
said tube has a linear slot a first radial slot that elevates said ear above said planar supporting surface and at least a second radial slot between said first radial slot and said planar supporting surface, said radial slots both being parallel to said planar supporting surface to allow said ear to move and rotate within said linear slot and said at least two radial slots;
said spring is arranged within said tube and around said central shaft to exhort force on said slider towards said planar supporting surface whereby said ear is adapted to clamp a wall or ceiling between said planar supporting surface and said ear, andwhen said slider is extended to said supporting surface, said central shaft is rotatable within said second radial slot to move said ear off of said wall or said ceiling whereby allowing removal of said fixture housing.

Abstract
Improvements in a fixture housing with dog ears is disclosed that can be installed from one side of a wall or ceiling. This increases the ability of the installer to place the fixture in a desired location as opposed to using a location that provides the best access on stud or joists. Once the ideal location is identified the installer uses a saw to cut an opening in the desired location. The housing is pushed into the opening for installation without requiring access to the back of the wall, ceiling or floor. The fixture housing uses a plurality of spring loaded dogs that are operated from the visible wall or ceiling surface. It is also possible for the fixture to be removed by lifting the locking tabs and sliding securing ears where the entire fixture can then be pulled back through the open hole.

11. A fixture housing with dog ears comprising:
-
a planar supporting surface; said planar supporting surface having an opening; said planar supporting surface having a plurality of tubes extending perpendicular to said planar supporting surface on a first side of said planar supporting surface; each of said plurality of tubes having a threaded central shaft and a slider; said slider is keyed to each said respective tube whereby rotation of said threaded central shaft rotates said slider; said slider has an ear that extends outside of said tube; said tube is movable within said planar supporting surface with said slider and said threaded central shaft; said tube has a linear slot whereby said ear rotates and translates within said linear slots; rotation of said threaded central tube in a first direction rotates said slider to a first stop and further rotation of said threaded central shaft translates said slider on said threaded central shaft; an end of said ear is rotatable over and above said planar supporting surface whereby said ear is adapted to clamp a wall or ceiling between said planar supporting surface and said ear, and when said slider is extended to said supporting surface, said central shaft is rotatable in a second direction, in said second direction of rotation, said ear translates to unclamp said ear off of said wall or said ceiling, and further rotation of said threaded central tube in said second direction rotates said ear clear of said wall or ceiling, whereby allowing removal of said fixture housing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
