Abstract
A recessed lighting fixture has a housing sidewall with a lip around a bottom aperture and a vertical T-slot receiving a locking assembly mounting the housing in an opening in a ceiling with the lip around a lower edge of the opening. The locking assembly has a support member with a lower strut portion and an upper attachment portion pivotally connected to a latching member. The strut portion has legs inserted through the slot so that edges of opposite walls and an axial end of a channel section base provide a U-shape line contact with the ceiling upper surface and upper teeth engage friction surfaces on opposite outside edge portions of the slot. The latching member has a handle carrying a tongue wedged between the legs by pivoting to engage locking feet with friction surfaces on opposite inside edge portions of the slot retaining the lighting fixture in the ceiling.
