  • Patent number: 7413456
    Abstract: The present invention relates to an electrical socket for a standard light bulb. The socket is configured to allow the bulb to be pushed into and pulled from the socket. The sockets are provided with spring members where the spring members have ridges thereon to engage the threaded end of the light bulb. The spring members are unevenly spaced about the circumference of the socket and the spring members are provided with an upper end that can move vertically away from the bottom of the socket. When a bulb is pushed into the socket, the force of the bulb on ridges on the spring members cause the spring members to elongate and allow the bulb to slide into the socket. When the bulb is pulled from the socket the spring members elongate allowing the bulb to slide from the socket.
