Abstract
Abstract A connecting device for securing a vertically suspended lighting fixture to the housing of an electrical junction (wiring) box in such a manner that the lighting fixture can be pivoted to an open position to enable interconnection of the fixture's and junction box's electrical wiring in a safe, facile manner. The device includes a safety means to prevent accidental removal (separation) of the fixture and junction box while in the pivoted, open position. In a preferred embodiment, the invention includes a pair of planar, substantially rectangular plate members. A first of these members is designed for being attached to the junction box and the second for being secured to the lighting fixture. Located on the second plate is a pair of upwardly projecting tab members adapted for being inserted within a corresponding pair of elongated openings located within the first plate member. The safety means is in the form of an upwardly projecting segment located on an upper surface of the first plate, said segment designed for being engaged by one of the projecting tab members during the described, pivoted position of the lighting fixture.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
250 words
A device for connecting a substantially vertically oriented lighting fixture to an electrical junction housing, said device comprising: a first plate member for being secured to said electrical junction housing and including at least one elongated opening therein; a second plate member for being secured to said lighting fixture and for being removably connected to said first plate member, said second plate member including at least one projecting tab member located thereon or forming part thereof and adapted for being inserted within said elongated opening of said first plate member in a first direction and thereafter moved in a second direction to engage said first plate member, said second plate member adapted for occupying a first, closed position against said first plate member and for pivoting to a second, open position located at a predetermined angle from said first plate member; means for detachably securing said first and second plate members when said second plate member occupies said first, closed position against said first plate member, and safety means for preventing accidental removal of said second plate member from said first plate member when said second plate member occupies said second, open position with respect to said first plate member, said safety means including a projecting segment located on or forming part of said first plate member, said tab member engaging said projecting segment when said second plate member occupies said second open position to prevent said tab member from moving in a direction substantially opposite to said second direction.
Claim 2
Independent Claim
250 words
A device for connecting a substantially vertically oriented lighting fixture to an electrical junction housing, said device comprising: a first plate member for being secured to said electrical junction housing and including at least one elongated opening therein; a second plate member for being secured to said lighting fixture and for being removably connected to said first plate member, said second plate member including at least one projecting tab member located thereon or forming part thereof and adapted for being inserted within said elongated opening of said first plate member in a first direction and thereafter moved in a second direction to engage said first plate member, said second plate member adapted for occupying a first, closed position against said first plate member and for pivoting to a second, open position located at a predetermined angle from said first plate member; means for detachably securing said first and second plate members when said second plate member occupies said first, closed position against said first plate member, and safety means for preventing accidental removal of said second plate member from said first plate member when said second plate member occupies said second, open position with respect to said first plate member, said safety means including a projecting segment located on or forming part of said first plate member, said tab member engaging said projecting segment when said second plate member occupies said second open position to prevent said tab member from moving in a direction substantially opposite to said second direction.
Claim 3
Dependent Claim
21 words
The connecting device according to claim 1 wherein said first plate member is substantially planar and of a substantially rectangular configuration.
Claim 4
Dependent Claim
21 words
The connecting device according to claim 2 wherein said second plate member is substantially planar and of a substantially rectangular configuration.
Claim 5
Dependent Claim
45 words
The connecting device according to claim 3 wherein said first and second plate members each include a wire passage aperture therein, said apertures being aligned with each other when said second plate member occupies said first, closed position with respect to said first plate member.
Claim 6
Dependent Claim
48 words
The connecting device according to claim 3 wherein said means for detachably securing said first and second plate members comprises a screw member for being positioned through a first hole located within said second plate member and threaded into a second hole located within said first plate member.
Claim 7
Dependent Claim
79 words
The connecting device according to claim 5 wherein said first and second plate members each include an angled segment, said angled segments being oriented in an abutting relationship when said second plate member occupies said first, closed position, said first hole located within said second plate member being positioned within said angled segment of said second plate member, and said second hole located within said first plate member being positioned within said angled segment of said first plate member.
Claim 8
Dependent Claim
30 words
The connecting device according to claim 1 wherein said second plate member is substantially planar, said projecting tab member projecting in a substantially perpendicular manner from said second plate member.
Claim 9
Dependent Claim
52 words
The connecting device according to claim 1 wherein the number of said elongated openings is two and the number of said projecting tab members is two, each of said tab members adapted for being inserted with a respective one of said elongated openings to effect said engagement with said first plate member.
Claim 10
Dependent Claim
26 words
The connecting device according to claim 1 wherein said first plate member is substantially planar, said projecting segment projecting substantially perpendicular from said first plate member.
