US Patent 7174607 Card attachment

The present invention relates to a card attachment for holding cards. The jaws of the card attachment can be locking in a closed position to ensure a secure grip on a card. Plastic gripping pads are included to increase the friction between the card and the jaws. Side walls are included to limit the distance a card may be inserted into the card attachment. Limiting the insertion of a card in this manner allows a card to be held without covering large amounts of the card. The ratio of an insertion length to the length of the side wall is selected to allow a card to be held securely without covering excessive amounts of the card. Thus a card can be held without covering pictures, words, or indicia on the card.
