Patent ID: 8341988

Claim:
A device for securing a structure that includes a mating element comprising: a) an inner body having an inner surface adapted for attachment to a mating element, b) an outer cover located circumferentially about the inner body, the outer cover adapted to freely rotate around the inner body and a central longitudinal axis through the outer cover, the inner body and the mating element, c) a key having an outer shape configured for insertion into a like shaped opening in the outer cover, said key having first and second magnets located in first and second holes in a moveable frame, the frame positioned within a cavity in the key, the first and second holes spaced apart in relationship to each other, such that upon positioning of the key in the opening in the outer cover said first and second magnets are oriented with the south pole of the first magnet and the north pole of the second magnet facing the top of the inner body such that the south pole of the first magnet is adjacent the south pole of a longitudinally moveable magnet and the north pole of the second magnet is adjacent the north pole of the longitudinally moveable magnet such that the first and second magnets function to repel the longitudinally moveable magnet, and d) the longitudinally moveable magnetic comprising one or more magnets located in a central opening within the outer cover such that i. in the absence of the key inserted in the opening in the outer body, the longitudinally moveable magnet is in a first position held away from contact with the inner body by attraction to a magnetic plate within a surface of the cover adjacent to the longitudinally moveable magnet, and ii. with the key inserted into the opening in the outer body the longitudinally moveable magnet relocates to a second position spaced from the magnetic plate with a portion of the longitudinally moveable magnet residing in a bore in the top of the inner body, the outer cover, inner body, key and longitudinally moveable magnet in operative connection such that when the longitudinally moveable magnet is in the first position the outer cover rotates freely around the inner body and with the longitudinally moveable magnet in the second position the outer cover is operatively connected to the inner body such that a rotational force applied to the outer cover is transmitted to the inner body so as to rotate the inner body in relationship to the mating element.
