  • Patent number: 4355440
    Abstract: A wallet guard is disclosed for use with a wallet and adapted to be used when placed in a pocket having a lower seam and a pair of side seams defining the width thereof to prevent removal therefrom. The wallet guard comprises a base at one end of the guard having a front edge and a rear edge with a support member integrally formed with the base and extending upwardly therefrom and adapted to be slipped into the wallet. A pair of arms extending upwardly from the base is provided with each arm including a lower section integrally coupled to the base and an upper section terminating in a free end. The arms are movable between an open position and closed position. In the open position the distance between the free ends is normally greater than the width of the pocket such that the arms will be biased inwardly by the side seams when inserted into the pocket with the base adjacent the lower seam to provide the upper portion of the pocket in tension.
