Abstract

Abstract A recessed incandescent lighting fixture has a faceplate and a wireway spaced from the faceplate for holding a bulb socket and for effecting the electrical connections to the fixture. A substantially cylindrical thermal protector is connected to the wireway by a wireway extension comprising a flexible metallic conduit; and a bracket is disposed on the rear surface of the faceplate for releasably retaining the protector and conduit thereat. The bracket comprises a base member, a first mounting member having a first slot therein for releasably retaining the thermal protector, a second mounting member having two arms forming a second slot for releasably receiving the minor root diameter of the conduit, and a spacing member disposed in the slots for deflecting the two arms relative to each other at an angle substantially equal to the pitch of the conduit thread.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 204 words
In a recessed incandescent lighting fixture having a faceplate and a wireway spaced from said faceplate for holding a bulb socket and for effecting the electrical connections to the fixture, the improvement comprising: a substantially cylindrical thermal protector connected to said wireway by a wireway extension comprising a flexible metallic conduit; and a bracket for releasably retaining the protector and cable on the rear surface of the faceplate, the bracket comprising a base member mounted on the rear surface of the faceplate, a first mounting member extending outwardly from the base member and having means forming a first slot therein for releasably retaining the thermal protector, a second mounting member extending outwardly from the base member and spaced apart from the first mounting member, the second mounting member having means including two bendable arms forming a second slot for releasably receiving the minor root diameter of the conduit, and a spacing member having end portions disposed in the slots between the base member and the protector and conduit and having deflecting means disposed at the one end portion received in the second slot for deflecting the two arms relative to each other at an angle substantially equal to the pitch of the conduit thread.
Claim 2
Dependent Claim 204 words
In a recessed incandescent lighting fixture having a faceplate and a wireway spaced from said faceplate for holding a bulb socket and for effecting the electrical connections to the fixture, the improvement comprising: a substantially cylindrical thermal protector connected to said wireway by a wireway extension comprising a flexible metallic conduit; and a bracket for releasably retaining the protector and cable on the rear surface of the faceplate, the bracket comprising a base member mounted on the rear surface of the faceplate, a first mounting member extending outwardly from the base member and having means forming a first slot therein for releasably retaining the thermal protector, a second mounting member extending outwardly from the base member and spaced apart from the first mounting member, the second mounting member having means including two bendable arms forming a second slot for releasably receiving the minor root diameter of the conduit, and a spacing member having end portions disposed in the slots between the base member and the protector and conduit and having deflecting means disposed at the one end portion received in the second slot for deflecting the two arms relative to each other at an angle substantially equal to the pitch of the conduit thread.
Claim 3
Dependent Claim 32 words
The fixture according to claim 1, wherein the base and mounting members comprise planar metal material and the mounting members extend perpendicularly from the base member and are parallel to each other.
Claim 4
Dependent Claim 20 words
The fixture according to claim 2, wherein the base and mounting members are formed from one integral sheet of metal.
Claim 5
Dependent Claim 54 words
The fixture according to claim 1, wherein the first slot comprises a first portion receptive of the protector a reduced width second portion thereabove to retain said protector in place, a seat below the first portion upon which the spacing member rests, and a narrow slit extending below the seat towards the base member.
Claim 6
Dependent Claim 35 words
The fixture according to claim 4, wherein the protector has parallel surfaces at the connected end thereof, and wherein the first portion of the first slot is formed by parallel straight edges on the arms.
Claim 7
Dependent Claim 54 words
The fixture according to claim 1, wherein the second slot comprises a circular first portion having a reduced width at the top thereof to retain the conduit in place, a seat below the first portion on which the spacing member rests, and a narrow slit extending below the seat and towards the base member.
Claim 8
Dependent Claim 47 words
The fixture according to claim 1, wherein the spacing member has a planar portion, and said deflecting means comprises two slots in opposite sides of the planar portion disposed perpendicular to the direction between the first and second members and offset relative to each in said direction.
Claim 9
Dependent Claim 35 words
The fixture according to claim 7, wherein the spacing member further comprises a portion bent toward the base at the end portion received in the first slot to facilitate proper placement of said spacing member.
Claim 10
Dependent Claim 21 words
The fixture according to claim 1, wherein the base member has mounting holes therein for mounting the bracket on a faceplate.
