Abstract

Abstract A mounting system has a box which is open at one end and a plate dimensioned to cover the opening. A disengagable pivot is positioned at one edge of the box and plate. A hooking mechanical connection is located at the opposite end of the box and plate. The light fixture is attached to the system and the system is in turn attached to an overhead structure. The plate and box engage each other at the pivot so that the plate does not initially cover the open end of the box. Thereafter, the plate may be rotated on the pivot and be secured against the open end of the box by the hooking mechanical connection.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 267 words
A mounting system for suspending fixtures from overhead structures, the system comprising: (a) support means having an open side with first and second opposing ends at the open side; (b) plate means dimensioned to cover and conceal the open side of the support means with its first and second opposing ends covered by correspondingly opposing ends on said plate means; (c) disengageable pivot means adjacent the first ends of said open side and said plate means for disengageable inter-connection of the support and plate means, said disengageable pivot requiring a predetermined sequence of horizontal and vertical movements of said plate relative to said support means in order to disengage said plate means from said support means; (d) hooking means adjacent the second ends of said open side and plate means for latching said plate over said open side, said relationships being such that said plate hangs, but does not fall, from said support if said hooking means is accidentally unlatched; (e) means for attaching a light fixture to the mounting system before said disengageable pivot means is engaged; and (f) means for attaching the mounting system to an overhead structure; whereby the plate means and support means may be attached to each other at the disengageable pivot means without danger that said fixture may fall before the plate is closed against the open side, whereby after the pivot is engaged the plate may swing on the pivot and be secured by said hooking means against the open side, and whereby the lighting fixture must be lifted and shifted in order to disengage it from the support means.
Claim 2
Dependent Claim 267 words
A mounting system for suspending fixtures from overhead structures, the system comprising: (a) support means having an open side with first and second opposing ends at the open side; (b) plate means dimensioned to cover and conceal the open side of the support means with its first and second opposing ends covered by correspondingly opposing ends on said plate means; (c) disengageable pivot means adjacent the first ends of said open side and said plate means for disengageable inter-connection of the support and plate means, said disengageable pivot requiring a predetermined sequence of horizontal and vertical movements of said plate relative to said support means in order to disengage said plate means from said support means; (d) hooking means adjacent the second ends of said open side and plate means for latching said plate over said open side, said relationships being such that said plate hangs, but does not fall, from said support if said hooking means is accidentally unlatched; (e) means for attaching a light fixture to the mounting system before said disengageable pivot means is engaged; and (f) means for attaching the mounting system to an overhead structure; whereby the plate means and support means may be attached to each other at the disengageable pivot means without danger that said fixture may fall before the plate is closed against the open side, whereby after the pivot is engaged the plate may swing on the pivot and be secured by said hooking means against the open side, and whereby the lighting fixture must be lifted and shifted in order to disengage it from the support means.
Claim 3
Dependent Claim 28 words
The mounting system according to claim 1 wherein the disengageable pivot means includes a rod mounted on the support means and a notch formed on the plate means.
Claim 4
Dependent Claim 36 words
The invention according to claim 1 wherein the hooking means include a hooking element formed by an edge of the plate and a ridge formed on the support means which is engaged by the hooking element.
Claim 5
Dependent Claim 73 words
The invention according to claim 3 wherein the plate has a descending vertical wall which abuts a horizontal lip of the support means to prevent movement of the descending wall toward the lip unless the descending wall is first lifted over the lip and the hooking means cannot be moved away from the ridge unless the edge of the plate is lifted so that the hooking means may be moved over the ridge.
Claim 6
Dependent Claim 55 words
The invention according to claim 2 wherein the plate has a descending wall which abuts a horizontal lip of the support means when the plate sets at an oblique angle to the box to prevent the notch from becoming disengaged from the rod by movement of the plate in a direction parallel to its plane.
Claim 7
Dependent Claim 17 words
The invention of any one of the claims 1-5 wherein said support means is a junction box.
Claim 8
Dependent Claim 22 words
The invention of any one of the claims 1-5 wherein said support means is a cover member for closing a junction box.
Claim 9
Dependent Claim 177 words
A fixture support comprising support means having opposing edges, plate means for covering and concealing said support means, said plate means having opposing edges which are individually associated with corresponding opposing edges of said support means, a first pair of said individually associated edges having dismountable hinge means forming an interconnected hinge so that said plate and support means may be hingedly interconnected and then swing between opened and closed positions, said hinged interconnection being concealed by said plate when in said closed position and a second pair of said individually associated edges having latch means for securing said plate and support means while in said closed position, the hinge and latch and latch means being shaped and dimensioned so that said dismountable hinge means cannot become unhinged unless said plate and support means are first uniquely manipulated in both horizontal and vertical directions with respect to each other in a sequential manner which cannot normally occur responsive to a swinging of said plate on said hinge responsive to gravity acting on the weight of said fixture.
Claim 10
Dependent Claim 177 words
A fixture support comprising support means having opposing edges, plate means for covering and concealing said support means, said plate means having opposing edges which are individually associated with corresponding opposing edges of said support means, a first pair of said individually associated edges having dismountable hinge means forming an interconnected hinge so that said plate and support means may be hingedly interconnected and then swing between opened and closed positions, said hinged interconnection being concealed by said plate when in said closed position and a second pair of said individually associated edges having latch means for securing said plate and support means while in said closed position, the hinge and latch and latch means being shaped and dimensioned so that said dismountable hinge means cannot become unhinged unless said plate and support means are first uniquely manipulated in both horizontal and vertical directions with respect to each other in a sequential manner which cannot normally occur responsive to a swinging of said plate on said hinge responsive to gravity acting on the weight of said fixture.
Claim 11
Dependent Claim 50 words
The fixture support of claim 8 wherein said shape and dimension of said hinge and latch include vertical and horizontal walls positioned so that said plate must be slid and lifted simultaneously to enable said vertical and horizontal walls to pass each other before said hinge means may be dismounted.
Claim 12
Dependent Claim 71 words
The system of claim 1 wherein each of said fixtures has associated therewith a closed box containing electrical parts, said plate means being attached to the exterior of said box, and means for enabling at least a pair of wires to be brought out of said box and through said plate means whereby said fixture may be electrically connected to or disconnected from an external circuit without exposing said electrical parts.
