Abstract
Abstract An apparatus is provided for preventing the unauthorized use of an electrical device such as a power tool or television set. The apparatus has an enclosure having bottom and peripherally extending side walls and an open top portion affording an inner chamber. Spaced pairs of apertures are located at the top portion on opposite sides of the enclosure. An electrical plug and its associated cable are inserted into the chambe with the shackle of the lock then being inserted through the apertures so as to encircle the electrical cable when in the locked position to capture the electrical plug within the enclosure, thereby preventing unauthorized use.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
An apparatus for preventing the unauthorized use of an electrical device, the electrical device including an electrical conduit attached at one end to the electrical device, and at its other end to an electrical plug, the apparatus comprising: an enclosure having a bottom and a peripherally extending side wall affording an inner chamber, the enclosure having an open top portion through which the electrical plug can be inserted for positioning in the chamber; aperture means on opposite sides of the top portion of the enclosure; a removable lock provided with a locking mechanism and a shackle, the shackle being selectively movable with respect to the locking mechanism between locked and unlocked positions, the shackle being of a size to pass through said aperture means to restrict the size of said open top portion and to capture the entire electrical plug within the enclosure when the shackle is moved to locked positions; and conduit securing means provided on the enclosure for retaining the electrical conduit and the enclosure in assembled relation.
