Abstract
Abstract A flush box for plug receptacles, comprising a box means including an open face at one side thereof. A cover element is mounted on the open face of the box means and comprises a plate element having a door element pivotally mounted therein. The door element cooperates with the plate element to form the external peripheral shape of the cover element. The plate element and door element each have a semicircular access opening formed therein opposite to each other and complementary therewith so as to define a circular access opening when the door element is in its closed position. A flexible conduit extends through the circular access opening into the box means and has a first plug element secured thereto which matingly engages a second plug element in the box means. The first plug element is smaller in size than the door element to permit the first plug element to be easily inserted into the box means or withdrawn therefrom when the door element is in its open position. Means is also provided to yieldably maintain the door in its open position. The cover element also includes means to maintain the door element in its proper closed position.

Claim 1
Independent Claim
301 words
In a flush box for plug receptacles, a box means having at least one open face, a first plug element in said box means, a cover element on the open face of said box means, comprising a plate element, means securing said plate element to said box means, a single door element pivotally secured to said plate element, said door element cooperating with said plate element to form a portion of the external peripheral shape of said cover element, a semicircular access opening in said plate element at a position adjacent said door element, a complementary semicircular access opening in said door element opposite said access opening in said plate element, a flexible conduit extending through the adjacent access openings in said cover element and said door element and into said box means, and a second plug element on said conduit within said box means and matingly engaged with said first plug element, said second plug element being smaller than said door element to permit easy ingress and egress thereof with respect to said box means when said door element is pivoted outwardly with respect to said plate element to separate said semicircular access openings and to open a portion of the open face of said box means, a first bracket extending over said open face of said box means, said bracket having a portion intermediate its ends which is offset to one side of said access opening so as to leave the opposite side of said access opening free from obstruction, and said door element having a first screw member extending therethrough which is threadably received by said first bracket to maintain said door element in a closed position to permit said door element to cooperate with said plate element to form the external peripheral shape of said cover element.
Claim 2
Dependent Claim
301 words
In a flush box for plug receptacles, a box means having at least one open face, a first plug element in said box means, a cover element on the open face of said box means, comprising a plate element, means securing said plate element to said box means, a single door element pivotally secured to said plate element, said door element cooperating with said plate element to form a portion of the external peripheral shape of said cover element, a semicircular access opening in said plate element at a position adjacent said door element, a complementary semicircular access opening in said door element opposite said access opening in said plate element, a flexible conduit extending through the adjacent access openings in said cover element and said door element and into said box means, and a second plug element on said conduit within said box means and matingly engaged with said first plug element, said second plug element being smaller than said door element to permit easy ingress and egress thereof with respect to said box means when said door element is pivoted outwardly with respect to said plate element to separate said semicircular access openings and to open a portion of the open face of said box means, a first bracket extending over said open face of said box means, said bracket having a portion intermediate its ends which is offset to one side of said access opening so as to leave the opposite side of said access opening free from obstruction, and said door element having a first screw member extending therethrough which is threadably received by said first bracket to maintain said door element in a closed position to permit said door element to cooperate with said plate element to form the external peripheral shape of said cover element.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
24 words
A flush box according to claim 2 wherein said bracket has opposite ends which are aligned in approximate vertical alignment with said access opening.
Claim 5
Dependent Claim
59 words
The box of claim 1 wherein said cover element has an abutment bracket means secured thereto which is engageable with said door element to limit the inward pivotal movement of said door element with respect to said box means so that said external peripheral shape is maintained when said screw member draws said door element into its closed position.
Claim 6
Dependent Claim
