US Patent 7651305 Retractable fitting

A retractable fitting assembly may include a cover that is rotatable around a first axis between closed and open positions, and a fitting that is rotatable around a second axis between closed and open positions. The first and second axes may be spaced apart and generally parallel. The direction of rotation of the fitting from the closed position to the open position may be opposite the direction of rotation of the cover from the closed position to the open position. In the closed position of the cover and the open position of the fitting, at least a portion of the cover abuts the fitting to thereby hinder rotation of the fitting.
