Total Claims: 8
Claim 1
Independent Claim
288 words
A snap-together light fixture comprising: a wall or ceiling pan having a generally flat front wall, and having means for supporting said front wall in spaced relationship to a junction box; a metal cup having an open top and a bottom wall, said bottom wall thereof being releasably supported by the front surface of said front wall of said pan; said front wall of said pan and said bottom wall of said cup having formed therein congruent circular openings and congruent pairs of opposed cutouts in the circumferential edges of said openings; a bulb socket having a generally cylindrical body, the bulb-receiving end of said body being open to form a socket and being internally threaded, and the base end of said socket body being closed and having a pair of electrical terminals thereon for energizing said socket and also having the central portion of a generally U-shaped spring steel strap attached thereto with the legs of said strap extending along the sides of said body and toward said open end thereof; said open end of said socket body being received within said metal cup, said base end thereof having a reduced exterior diameter forming a circumferential shoulder about mid-way of the length of said socket body, said base end of said socket body extending through said congruent circular openings of said metal cup and pan wall and therebeyond with said shoulder removably engaging the inner surface of said metal cup bottom wall; and the extremities of said strap legs having outwardly opening hooks formed therein, said strap legs being inwardly flexed and said hooks thereof engaging said cutouts of both said pan and said cup for securing the same to each other and said socket to them.

A snap-together light fixture comprising: a wall or ceiling pan having a generally flat front wall, and having means for supporting said front wall in spaced relationship to a junction box; a metal cup having an open top and a bottom wall, said bottom wall thereof being releasably supported by the front surface of said front wall of said pan; said front wall of said pan and said bottom wall of said cup having formed therein congruent circular openings and congruent pairs of opposed cutouts in the circumferential edges of said openings; a bulb socket having a generally cylindrical body, the bulb-receiving end of said body being open to form a socket and being internally threaded, and the base end of said socket body being closed and having a pair of electrical terminals thereon for energizing said socket and also having the central portion of a generally U-shaped spring steel strap attached thereto with the legs of said strap extending along the sides of said body and toward said open end thereof; said open end of said socket body being received within said metal cup, said base end thereof having a reduced exterior diameter forming a circumferential shoulder about mid-way of the length of said socket body, said base end of said socket body extending through said congruent circular openings of said metal cup and pan wall and therebeyond with said shoulder removably engaging the inner surface of said metal cup bottom wall; and the extremities of said strap legs having outwardly opening hooks formed therein, said strap legs being inwardly flexed and said hooks thereof engaging said cutouts of both said pan and said cup for securing the same to each other and said socket to them.
Claim 3
Dependent Claim
20 words
A light fixture as in claim 1 wherein said bottom end of said metal cup directly engages said pan wall.
Claim 4
Dependent Claim
44 words
A light fixture as in claim 1 which additionally includes an ornamental plate disposed between said pan front wall and said cup bottom end, and also having a congruent circular opening and opposed cutouts; said spring hooks securing said pan, plate, and cup together.
Claim 5
Dependent Claim
80 words
A snap-together light fixture including a bulb receiving socket having associated spring means for releasably locking the socket in a support, a metal cup for receiving and enclosing the socket, and a base member adapted to fit upon a wall or ceiling, the cup and base member cooperatively supporting the socket by means of openings through which the socket extends, while the spring means of the socket releasably grasps the edges of the openings for holding all three parts together.
Claim 6
Dependent Claim
80 words
A snap-together light fixture including a bulb receiving socket having associated spring means for releasably locking the socket in a support, a metal cup for receiving and enclosing the socket, and a base member adapted to fit upon a wall or ceiling, the cup and base member cooperatively supporting the socket by means of openings through which the socket extends, while the spring means of the socket releasably grasps the edges of the openings for holding all three parts together.
Claim 7
Dependent Claim
137 words
A snap-together light fixture comprising: a plurality of bulb-receiving sockets each having associated spring means for releasably locking the socket in a support; a plurality of metal cups for receiving and enclosing respective ones of said sockets, each of said cups having a bottom wall with a central opening therein; and a base member adapted to fit upon a wall or ceiling and having a plurality of openings therein for receiving respective ones of said sockets; each of said cups having its bottom wall supported upon said base member with the central opening thereof aligned with a corresponding opening of said base member, the associated socket being disposed within said cup and extending through said aligned openings, and the spring means of the socket releasably grasping the edges of the openings for holding all three parts together.
