Abstract
Abstract An electrical connector box adapted to be used in connection with the raised floor concept with a raised floor positioned above the main floor. A plurality of substantially rectangular openings are formed in the raised floor. A frame is positioned in the openings. The electrical connector box is lowered into engagement with the frame and into the space between the raised floor and the main floor. The electrical connector unit includes flange means which is adapted to rest adjacent the raised floor to suspend the electrical connector unit between the floors. The unit further includes flange means engaging the under-surface of the raised floor to maintain the unit in position. A sling or saddle-like structure extends downwardly from the electrical connector box into the space between the raised floor and is adapted to receive wires, cables and the like. There is a hinged top plate movable to a first position providing access to the interior of the electrical connector box and a second closed position. Finger-like openings in the top plate provide access to the electrical connector box when the top plate is in the closed position so that wires, etc. can be connected to various types of electrical equipment.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
174 words
An electrical connector unit adapted for use in combination with a raised floor wherein the raised floor is spaced above the regular floor so that there is a space between the floors for wire and cables to be electrically connected to the electrical connector, there being a plurality of substantially rectangular openings through the raised floor, comprising: a. substantially rectangular frame means adapted to fit within one of the openings in said raised floor; b. sling shaped means extending downwardly from opposing sides of the frame adapted to receive a variety of electrical connections, c. means connected to said frame adapted to rest on the top surface of said raised floor so that the electrical connector is suspended in the space between the regular floor and the raised floor, and d. locking means having a first and a second position connected to said frame adapted to engage said raised floor to maintain the electrical connector unit in plane in a first position and to permit removal of the electrical connector in a second position.
Claim 2
Dependent Claim
174 words
An electrical connector unit adapted for use in combination with a raised floor wherein the raised floor is spaced above the regular floor so that there is a space between the floors for wire and cables to be electrically connected to the electrical connector, there being a plurality of substantially rectangular openings through the raised floor, comprising: a. substantially rectangular frame means adapted to fit within one of the openings in said raised floor; b. sling shaped means extending downwardly from opposing sides of the frame adapted to receive a variety of electrical connections, c. means connected to said frame adapted to rest on the top surface of said raised floor so that the electrical connector is suspended in the space between the regular floor and the raised floor, and d. locking means having a first and a second position connected to said frame adapted to engage said raised floor to maintain the electrical connector unit in plane in a first position and to permit removal of the electrical connector in a second position.
Claim 3
Dependent Claim
64 words
An electrical connector unit as defined in claim 1 having a hinge means and a top cover plate, said hinged means being connected to said frame and said top cover plate so that said top plate has a first position wherein the interior of the electrical connector unit is closed and a second position wherein the interior of the electrical connector unit is open.
Claim 4
Dependent Claim
27 words
An electrical connector unit as defined in claim 1 wherein said locking means connected to the frame is adapted to engage the undersurface of the raised floor.
Claim 5
Dependent Claim
54 words
An electrical connector unit as defined in claim 3 wherein said locking means consists of pivot means attached to said frame, a flange means connected to said pivot means so that the flange means has a first inward position and a second outward position wherein said flange engages the undersurface of the raised floor.
Claim 6
Dependent Claim
173 words
An electrical connector unit particularly adapted for use with a raised floor positioned above a regular floor, forming a space therebetween, comprising, in combination: a. a plurality of substantially rectangular openings extending through the raised floor; b. a substantially rectangular frame for the electrical connector unit; c. sling means extending downwardly from opposing sides of said frame adapted to accommodate different electrical connections; d. flange means extending outwardly from each side of said frame means adapted to rest upon the upper surface of said raised floor; e. locking means connected to said frame means adapted to engage the undersurface of said raised floor whereby said electrical connector unit is removably suspended in the space between said raised floor and the main floor; f. a first hinge means attached to one side of said frame; g. a top plate attached to said first hinge means and adapted to be moved to a first open position whereby desired wiring can be accomplished and a second closed position whereby the top plate serves as a floor.
Claim 7
Dependent Claim
173 words
An electrical connector unit particularly adapted for use with a raised floor positioned above a regular floor, forming a space therebetween, comprising, in combination: a. a plurality of substantially rectangular openings extending through the raised floor; b. a substantially rectangular frame for the electrical connector unit; c. sling means extending downwardly from opposing sides of said frame adapted to accommodate different electrical connections; d. flange means extending outwardly from each side of said frame means adapted to rest upon the upper surface of said raised floor; e. locking means connected to said frame means adapted to engage the undersurface of said raised floor whereby said electrical connector unit is removably suspended in the space between said raised floor and the main floor; f. a first hinge means attached to one side of said frame; g. a top plate attached to said first hinge means and adapted to be moved to a first open position whereby desired wiring can be accomplished and a second closed position whereby the top plate serves as a floor.
Claim 8
Dependent Claim
65 words
An electrical connector unit as defined in claim 5 wherein said locking means comprises a pivot extending along opposing sides of said frame, flange means including a raised floor engaging position attached to said pivot means, said flange means being movable to a first inward out-of-the-way position and a second locking position wherein said raised floor engaging position engages the undersurface of said raised floor.
Claim 9
Dependent Claim
