Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
200 words
In an electrical panel including an enclosure with front edges defining a front opening and wherein said enclosure has separate compartment areas exposed through said front opening, a front cover assembly for closing said front opening, said assembly comprising: first and second cover sections each closing a separate one of said compartment areas; said first and second cover sections having mutually engaging side surfaces detachably connecting the cover sections together; One of said side surfaces extending rearward from the face of said second cover section so as to terminate at an inturned edge directed toward said enclosure; the other of said side surfaces being formed by a channel recessed into the face of said first cover section such that said other side surface terminates at a front edge directed away from said enclosure, said channel receiving said one side surface so that the face of said second cover section covers said front edge of said other side surface; and removable fastener means securing said first and second cover sections together along said side surfaces such that said second cover section is detachable from said first cover section so as to open the compartment area closed by the second cover section.
Claim 2
Dependent Claim
200 words
In an electrical panel including an enclosure with front edges defining a front opening and wherein said enclosure has separate compartment areas exposed through said front opening, a front cover assembly for closing said front opening, said assembly comprising: first and second cover sections each closing a separate one of said compartment areas; said first and second cover sections having mutually engaging side surfaces detachably connecting the cover sections together; One of said side surfaces extending rearward from the face of said second cover section so as to terminate at an inturned edge directed toward said enclosure; the other of said side surfaces being formed by a channel recessed into the face of said first cover section such that said other side surface terminates at a front edge directed away from said enclosure, said channel receiving said one side surface so that the face of said second cover section covers said front edge of said other side surface; and removable fastener means securing said first and second cover sections together along said side surfaces such that said second cover section is detachable from said first cover section so as to open the compartment area closed by the second cover section.
Claim 3
Dependent Claim
55 words
The electrical panel of claim 1 wherein said enclosure includes a partition separating said compartment areas and said recessed channel of said first cover section extends parallel and adjacent to said partition so as to maintain the front edge of said partition covered when said second cover section is detached from said first cover section.
Claim 4
Dependent Claim
52 words
The electrical panel of claim 2 wherein said panel is a multimeter center with one of the compartments having supported therein plural watthour meter socket bases and being closed by said first cover section and with another of the compartments including circuit breaker receptacles and being closed by said second cover section.
Claim 5
Dependent Claim
25 words
The electrical panel of claim 3 wherein said first cover section includes plural openings for receiving watthour meter devices mountable on said meter socket bases.
Claim 6
Dependent Claim
68 words
The electrical panel of claim 2 wherein said side surface of said first cover section includes integral laterally outward extending projections defining a screw lance for receiving a screw, said second cover section includes a hole aligned with each screw lance, and said removable fastener means includes a screw received by the last named hole and aligned screw lance to clamp said first and second cover sections together.
Claim 7
Dependent Claim
81 words
The electrical panel of claim 4 wherein plural bracket members are fixedly attached at one end to said first cover section so that the other end extends rearwardly thereof and is exposed through the face of said first cover section by one of the meter openings, and a screw removably fastening said other end of said bracket to said enclosure within said one compartment such that said first cover section is secured to said enclosure independently of said second cover section.
