Abstract
Abstract A filler for an unused panelboard location is a one-piece unit constructed of relatively stiff resilient plastic material. Tablike formations at opposite ends of the unit define recesses that receive opposed edges of the face-plate opening. An integrally formed deflected arm transmits forces maintaining the filler in its operative position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
152 words
A filler for an opening in a trim plate, said filler including an elongated rectangular plate-like portion having first and second relatively short edges at opposite ends of said portion, first retaining formation means at said first edge defining a relatively shallow plate receiving first recess means at one of said ends and having an opening facing said first edge, second retaining formation means at said second edge defining a relatively deep plate receiving second recess means at the other of said ends and having an opening facing said second edge, an element mounted to said portion and positioned to engage a trim plate edge entered into said second recess means, biasing means acting on said element to create a reaction force which urges said filler away from a trim plate edge entered into said second recess means whereby another trim plate edge becomes more deeply positioned in said first recess means.
Claim 2
Dependent Claim
152 words
A filler for an opening in a trim plate, said filler including an elongated rectangular plate-like portion having first and second relatively short edges at opposite ends of said portion, first retaining formation means at said first edge defining a relatively shallow plate receiving first recess means at one of said ends and having an opening facing said first edge, second retaining formation means at said second edge defining a relatively deep plate receiving second recess means at the other of said ends and having an opening facing said second edge, an element mounted to said portion and positioned to engage a trim plate edge entered into said second recess means, biasing means acting on said element to create a reaction force which urges said filler away from a trim plate edge entered into said second recess means whereby another trim plate edge becomes more deeply positioned in said first recess means.
Claim 3
Dependent Claim
26 words
A filler as set forth in claim 1 in which the plate-like portion, the first and second retaining formation means, and the element are integrally formed.
Claim 4
Dependent Claim
19 words
A filler as set forth in claim 2 in which the biasing means is formed integrally with the element.
Claim 5
Dependent Claim
13 words
A filler as set forth in claim 3 constructed of resilient plastic material.
Claim 6
Dependent Claim
23 words
A filler as set forth in claim 1 in which there are depending lips along the relatively long edges of the plate-like portion.
Claim 7
Dependent Claim
26 words
A filler as set forth in claim 5 in which the element extends from one of the lips stopping short of the other of the lips.
Claim 8
Dependent Claim
24 words
A filler as set forth in claim 6 in which the second retaining formation means is part of said lips at one end thereof.
Claim 9
Dependent Claim
44 words
A filler as set forth in claim 7 in which the first retaining formation means is inboard of the lips and the other ends of the lips limit movement of said filler by engaging a trim plate edge entered into the first recess means.
Claim 10
Dependent Claim
31 words
A filler as set forth in claim 7 in which the plate-like portion, the first and second retaining formation means, the lips, the biasing means, and the element are integrally formed.
Claim 11
Dependent Claim
13 words
A filler as set forth in claim 9 constructed of resilient plastic material.
