Abstract
Abstract A flush box for plug receptacles is disclosed herein which generally comprises 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 first and second plate elements which are pivotally secured together. The plate members cooperate to form the external peripheral shape of the cover element. The plate elements each have a semi-circular access opening formed therein opposite to each other and complementary therewith so as to define a circular access opening when the plate elements are in their normal 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. A flat hinge member pivotally connects the plate elements together to permit one of the plate elements to be moved with respect to the other plate element to permit the first plug element to be easily inserted into the box means or withdrawn therefrom when the one plate element has been pivotaly moved with respect to the other plate element. Means is also provided to yieldably maintain the plate elements in their assembled or closed position. A resilient grommet is positioned in the circular access opening when the plate elements are in their closed position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
262 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 first and second plate elements pivotally secured together, said plate elements being pivotally secured together about an axis which is transverse to the plane of said plate elements, said first and second plate elements having complementary semicircular access openings formed therein which cooperate to form a circular access opening when said plate elements are in a first position, said plate elements cooperating to form the peripheral shape of said cover element when in said first position, said first plate element being pivotally movable from its first position to a second position with respect to said second plate element to separate said semi-circular access openings and to open a portion of the open face of said box means, a flexible conduit extending through the circular access opening in said cover element, 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 the said portion of the open face of said box means to permit easy ingress and egress thereof with respect to the box means when said first plate element has been moved to its said second position, and screw elements extending through each of said plate elements to maintain said cover element on the open face of said box means and to maintain said plate elements in said first position.
Claim 2
Dependent Claim
