ABSTRACT:
An automatic electric plug release consisting of a hollow receptacle in which the electrical plug is spring mounted. The spring is held under compression by a rotatable mounting member on which the electrical plug is mounted. The spring is mounted between the rotatable member and an inside flange on the bottom portion of the casing. A cover is removably mounted on the casing and is formed with at least two lugs which engage the rotatable member to hold it in a locked position to compress the spring. In the latter position the terminal prongs project out from the receptacle and may be inserted into an electrical wall socket. The cover has an angled sleeve through which the electrical cord is introduced and connected to the electrical socket in the usual manner. A pull on the electrical cord will rotate the mounting member sufficient to release the member from the locked position and allow the spring action to actuate the member upwards and withdraw the terminal prongs from the socket.
