Automatic extending member selector

A device for selectively extending one member selected from a plurality of extending members having mounting apertures, when retained in said device said device comprising,

• a frame assembly comprising parallel side plates, including a first side plate and a second side plate, spaced apart from each other, a rear wall connecting said side plates at one longitudinal edge of said side plates and a bottom plate bridging said side plates at a bottom portion of said side plates, said side plates, rear wall, and bottom plate defining an open cavity of sufficient depth to allow for partial enclosure of extending members to be retained, said cavity being open in a frontal position parallel to said rear wall, and in a top position parallel to said bottom plate;
• a hollow shaft extending between said side plates through throughholes, said shaft being capable of mating with mounting apertures of the extending members whereby the extending members can be rotatably mounted on said shaft, said shaft further having an open raceway formed therein;
• a selector capable of selecting one retained extending member, said selector comprising a cylindrical member having a tailpiece extending therefrom, said selector being positioned within said hollow shaft with said tailpiece extending through said raceway to an exterior of said shaft whereby said shaft is capable of contacting a retained extending member selected for extension, said selector being movable within said shaft between said side plates,
• a selector control for controlling said position of said selector,
• a shaft biasing member for biasing said shaft to rotate between a closed position and an extended position, a retarding member preventing said shaft from rotating, and a release member for releasing said retarding member whereby said shaft is rotated by force of said biasing member.
