Abstract

Disclosed is a sound insulating container for completely enclosing an electrical appliance. The container includes walls constructed of sound absorbing material and a door attached by hinges for completely closing the container. An electrical outlet is provided inside the container and is connected to a standard wall outlet by a conventional electric cord. A switch provided on the exterior of the container when the door is closed selectively supplies power to the interior outlet.

Claims

a body having at least side walls, a bottom wall, and a rear wall, all constructed of sound absorbing material;

a door constructed of sound absorbing material for forming a sealed enclosure when in a closed position;

an electric cord attached at the exterior of said body;

an electrical outlet inside said body and electrically connected to said electric cord;

an electrical switch located on the exterior of said body when said door is in its closed position and electrically connected to said interior electrical outlet for selectively supplying electrical power to said outlet.

2. The sound insulating container of claim 1 wherein said sound insulating material comprises interior and exterior faces of plastic and plywood, respectively, surrounding a layer of foam rubber adjacent the plastic and a layer of Homasote board sandwiched between the foam rubber and plywood.

3. The sound insulating container of claim 1 wherein said door is pivotal between open and closed positions and is locked in a closed position by a latching mechanism.
