Description
Background of the Invention
1. Field of Invention
The present invention relates to an electrical outlet box adapted for positioning over a pair of electrical wall outlets and secured to the wall and having a slotted lockable cover on the box adapted to receive an electrical cord terminating in a plug for registry within an outlet.
2. Description of the Prior Art
The present invention is provided because of the high rate of home and business thefts. In most thefts, articles of an electrical nature are the most sought after such as televisions and radios, etc. At the present time, removal of such articles by a thief is a simple matter of unplugging the item and taking it.
Summary of the Invention
An important feature of the present invention is to provide a locking electrical outlet box to prevent removal of the electrical plug to reduce such losses. The electrical locking outlet box has the further feature of protecting children and preventing unauthorized persons from access to the electrical wall outlet.
A further feature is to provide a metal box of sufficient thickness so as to provide an enclosure strong enough to support a key lock and clip together with a hinged cover for opening and closing the box and including a latch bar registerable with the latch upon the key lock.
Another feature includes easy installation of the box over a pair of electrical outlets by the use of existing screws and the existing face plate with standard hole patterns.
Another feature is to provide upon the hinged cover for the box of aligned outwardly opening slots which are adapted to receive an electrical cord which terminates in an electrical prong plug enclosed within the box and adapted for registry within an electrical wall outlet.
These and other features and objects will be seen from the following specification and claims in conjunction with the appended drawing.

Description of a Preferred Embdodiment of the Invention
Referring to the drawing, the present locking electrical outlet box made of metal, generally designated at 11, FIG. 1 is adapted for positioning over a pair of electrical wall outlets 13 having a conventional face plate 23.
Fastener aperture 15 extends through bottom wall 17 of the box which includes a pair of electrical outlet clearance apertures 19 in registry with electrical outlets 13. Said bottom wall includes a pair of box mount apertures 21 adapted to receive conventional fasteners for securing the box to the wall or to connector portions of the conventional electrical outlets 13.
The conventional or standard face plate 23, FIG. 1, includes outlet apertures 25 and a central fastener aperture 27 adapted to receive the existing fastener by which the face plate is normally mounted upon the wall so as to overlie a pair of electrical outlets in a conventional manner.
The present locking electrical outlet box 11 includes a cover 29 hinged at 31 along one edge to one of the side walls 34 of said box and includes a pair of laterally spaced aligned outwardly opening electrical cord slots 33.
Key lock 35 of a conventional construction normally including a rotatable cylinder is projected through one of the side walls 34 and anchored in position by the lock clip 37, FIG. 2. Key lock 35 normally has a rotatable cylinder which terminates in the transverse latch 39 normally positioned within said box and adapted for retaining registry with a corresponding depending apertured latch bar 41 upon the interior of box cover 29.
In the illustrative embodiment, the dimensions of the locking electrical outlet box for the standard two plug electrical outlet are approximately 11/2 inches in depth, 41/2 inches in length and 23/4 inches wide. It is contemplated that the sides of the box can be enlarged for other multiple outlets.
The present locking electrical outlet box is constructed for easy installation by utilizing existing screws, the existing face plate and standard hole patterns. The three apertures 15 and 21 in bottom wall 17 of said box provide clearance for existing screws by which the box bottom 17 is mounted over a pair of spaced electrical wall outlets 13, FIG. 1. Corresponding apertures 19 in said bottom wall are adapted for clearance registry with said electrical outlets.
The pair of slots 33 in cover 29 provide for assembly and clearance of one or a pair of wires or cords therethrough, FIG. 1, before the cover is moved to a closed position and wherein the respective cords terminate in conventional prong plugs for registry within the corresponding one or a pair of wall outlets 13. The cords, not shown, extend for any electrical appliance, such as a TV, radio, etc.
After such registry, with the cover 29 closed, key operated lock 35 is adjusted so that the corresponding latch 39 moves into interlocking retaining registry with the corresponding apertured latch bar 41 depending from cover 29.
As an alternate use of the present locking electrical outlet box, the corresponding electrical prong plug or plugs of a pair of wires may be lockingly retained within the box 11 and not necessarily projected within the corresponding electrical outlets 13. This provides a means for preventing unauthorized use of the electrical appliance or other unauthorized usage of electrical outlets.
Claims
I claim:
