Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A cover assembly for use in a panelboard having a cabinet supporting an interior assembly for extending a plurality of electrical connections with said cabinet including a back wall having a peripheral wall formed by side walls transverse to said back wall with each side wall having projecting flanges in spaced overlapping relationship to said back wall, the improvement comprising: a cover adapted to extend past each of said flanges, a plurality of spaced latch lever assemblies, first pivot means for each latch lever assembly pivotally supporting a respective one of said latch lever assemblies for rotation about a respective axis located at a respective position spaced intermediate said flanges for engaging a respective one of said flanges, and second means for each first means for pivotally supporting a respective one of said first pivot means for thereafter rotating each latch lever assembly relative said cover about another respective axis for moving said cover toward said flanges.
Claim 2
Dependent Claim
157 words
A cover assembly for use in a panelboard having a cabinet supporting an interior assembly for extending a plurality of electrical connections with said cabinet including a back wall having a peripheral wall formed by side walls transverse to said back wall with each side wall having projecting flanges in spaced overlapping relationship to said back wall, the improvement comprising: a cover adapted to extend past each of said flanges, a plurality of spaced latch lever assemblies, first pivot means for each latch lever assembly pivotally supporting a respective one of said latch lever assemblies for rotation about a respective axis located at a respective position spaced intermediate said flanges for engaging a respective one of said flanges, and second means for each first means for pivotally supporting a respective one of said first pivot means for thereafter rotating each latch lever assembly relative said cover about another respective axis for moving said cover toward said flanges.
Claim 3
Dependent Claim
151 words
A cover assembly for use in a panelboard having a cabinet supporting an interior assembly for extending a plurality of electrical connections with said cabinet including a back wall having side walls transverse to said back wall with each side wall having projecting flanges in spaced overlapping relationship to said back wall, the improvement comprising: a cover adapted to extend past each of said flanges, and a plurality of sapced latch lever assemblies, each latch lever assembly comprising a U shaped clamp member having side legs transverse to said flanges, a first pivot means extending through said cover and the back leg of said clamp member to provide one axis of rotation spaced intermediate said flanges for rotating each member to a position in registration with said flanges, and second pivot means for rotating each first pivot means and member about a second axis for moving said cover toward said flanges.
Claim 4
Dependent Claim
151 words
A cover assembly for use in a panelboard having a cabinet supporting an interior assembly for extending a plurality of electrical connections with said cabinet including a back wall having side walls transverse to said back wall with each side wall having projecting flanges in spaced overlapping relationship to said back wall, the improvement comprising: a cover adapted to extend past each of said flanges, and a plurality of sapced latch lever assemblies, each latch lever assembly comprising a U shaped clamp member having side legs transverse to said flanges, a first pivot means extending through said cover and the back leg of said clamp member to provide one axis of rotation spaced intermediate said flanges for rotating each member to a position in registration with said flanges, and second pivot means for rotating each first pivot means and member about a second axis for moving said cover toward said flanges.
Claim 5
Dependent Claim
60 words
The improvement claimed in claim 2 in which each lever assembly comprises lever engaged with said clamp member for manually pivoting said clamp member about said axis, and a coil spring between said lever and said clamp member for biasing one end of said side legs from said cover about said other axis transverse to said one axis of rotation.
Claim 6
Dependent Claim
38 words
The improvement claimed in claim 3 in which said pivot means comprises a threaded member threaded through said clamp member for moving said one end of said clamp member side legs against said bias toward a respective flange.
Claim 7
Dependent Claim
18 words
The improvement claimed in claim 4, means for supporting said lever relative said cover at two spaced positions.
Claim 8
Dependent Claim
27 words
The improvement claimed in claim 5, a detent carried by said cover for engaging said lever is response to rotation of said lever between two spaced positions.
Claim 9
Dependent Claim
36 words
The improvement claimed in claim 1 in which said interior assembly is overlapped by a trim assembly having a peripheral flange, and said cover includes a pair of spaced rabbets for nestingly receiving said peripheral flange.
Claim 10
Dependent Claim
27 words
The improvement claimed in claim 4 in which said cover has a flange for engaging one of said cabinet flanges for carrying the weight of said cover.
