Drop down diffuser frame for a ceiling light fixture

A ceiling light comprising light fixture means adapted for mounting on a ceiling, said light fixture means including a portion projecting generally downward from the ceiling and a lip projecting upward at an edge thereof, and a diffuser frame for suspending a diffuser under said light fixture mean,, the diffuser frame comprising a plurality of frame members disposed in the form of a closed geometric shape such as a rectangle the having an open bottom and an open top, spring latch means mounted on an inner surface of a first one of said frame members, and support means mounted on an inner surface of a second one of said frame members, said spring latch means being adapted for latching connection to said light fixture means for holding the diffuser frame in a closed position in which the diffuser and diffuser frame substantially enclose said light fixture means with said frame members generally abutting the ceiling, said support means including a ramp portion and a catch portion, said ramp portion being adapted to rest on said light fixture means lip generally at its upper edge for supporting he diffuser frame at one side thereof in said closed position with said catch portion being disposed above and inward of said lip, the diffuser frame being adapted for movement to an open position by disconnecting said spring latch means from said light fixture means thereby permitting the diffuser frame to drop generally downwardly with respect to said light fixture means with said ramp portion of said support means sliding on the upper edge of said lip of said light fixture means in a direction generally transverse to the upper edge of said lip thereby spacing said frame members from the ceiling, said catch portion being engageable with said lip thereby to stop the sliding of said ramp portion on said lip, the diffuser frame then being adapted to swing to said open position with said support means pivoting on said lip and with said frame members having sufficient clearance from the ceiling to allow the diffuser frame to swing to said open position.

A ceiling light comprising a reflector, means mounting the reflector to a ceiling, the reflector including a portion projecting generally downward from the ceiling and a lip projecting upward at an edge thereof, means for mounting a lamp on the reflector, a diffuser, and a diffuser frame for suspending the diffuser under the lamps mounted on the reflector, the diffuser frame comprising a plurality of frame members disposed in the form of a closed geometric shape such as a rectangle having an open bottom and an open top, spring latch means mounted on an inner surface of a first one of said frame members, and support means mounted on an inner surface of a second one of said frame members, said spring latch means being adapted for latching connection to the reflector for holding the diffuser frame in a closed position in which the diffuser and diffuser frame substantially enclose the reflector and lamps mounted thereon with said frame members generally abutting the ceiling, said support means including a ramp portion and a catch portion, said ramp portion being adapted to rest on the reflector lip generally at its upper edge for supporting the diffuser frame at one side thereof in said closed position with said catch portion being disposed above and inward of the lip, the diffuser frame being adapted for movement to an open position by disconnecting said spring latch means from the reflector thereby permitting the diffuser to drop generally downward and laterally with respect to the reflector with said ramp portion of said support means sliding on the upper edge of the lip of the reflector in a direction generally transverse to said upper edge of the lip thereby spacing said frame members from the ceiling, said catch portion being engageable with the lip thereby to stop the sliding of said ramp portion on the lip, the diffuser frame then being adapted to swing to said open position with said catch portion pivoting on the lip and with said frame members having sufficient clearance from the ceiling to allow the diffuser frame to swing to said open position.

A ceiling light comprising a reflector, means mounting the reflector to a ceiling, the reflector including a portion projecting generally downward from the ceiling and a lip projecting upward at an edge thereof, means for mounting a lamp on the reflector, a diffuser, and a diffuser frame for suspending the diffuser under the lamps mounted on the reflector, the diffuser frame comprising a plurality of frame members disposed in the form of a closed geometric shape such as a rectangle having an open bottom and an open top, spring latch means mounted on an inner surface of a first one of said frame members, a plurality of tongues mounted at intervals along an inner surface of a second one of said frame members, each tongue having a section forming a ramp portion sloping generally upward and inward from the inner surface of said second frame member generally in a plane intersecting the inner surface at an acute angle, and a hook-shaped section at the distal end of the tongue forming a catch portion, said ramp portion being adapted to rest on the reflector lip generally at its upper edge for supporting the diffuser frame at one side thereof in said closed position with said catch portion being disposed above and inward of the lip, the diffuser frame being adapted for movement to an open position by disconnecting said spring latch means from the reflector thereby permitting the diffuser to drop generally downward and laterally with respect to the reflector with said ramp portion of said support means sliding on the upper edge of the lip of the reflector in a direction generally transverse to said upper edge of the lip thereby spacing said frame members from the ceiling, said catch portion being engageable with the lip thereby to stop the sliding of said ramp portion on the lip, the diffuser frame then being adapted to swing to said open position with said catch portion pivoting on the lip and with said frame members having sufficient clearance from the ceiling to allow the diffuser frame to swing to said open position.
