  • Patent number: 4669733
    Abstract: A playing card holder is described in which two plates with diverging inner surfaces form a tapered slot which extends upward from a base section. The inner surface of each plate is lined with a layer of tufted flock material, which may be partially set into recesses in the opposed plate surfaces. The holder retains either a single card or a number of overlapping cards securely in place with a relatively high degree of static friction, and yet permits cards to be easily removed with a substantially lower dynamic friction without dislodging adjacent cards. The remote ends of the holder are provided with a compound curvature which protects the cards from casual visual observation by other players, while enhancing the ability of the player to easily and securely manipulate the cards.

  • Patent number: 4630824
    Abstract: A playing card holder is described in which two plates with diverging inner surfaces extend upward from a base section. The two plates diverge from each other within an angular range of about 1.degree.-8.degree., and preferably about 3.degree.-5.degree., to form a tapered slot within which the playing cards are inserted. The inner surface of each plate is lined with a layer of a flocked material, the layers being partially set into recesses in the opposed surfaces of each plate. The holder retains either a single card or a number of overlapping cards securely in place once they have been inserted into the slot, and yet permits cards to be easily removed without dislodging adjacent cards.

The holder retains either a single card or a number of overlapping cards securely in place once they have been inserted into the slot, and yet permits cards to be easily removed without dislodging adjacent cards. The remote ends of the holder are provided with a compound curvature in a direction generally perpendicular to the plane of the card holder which has been found to secure the cards from casual visual observation by other players, and yet preserves the ability of a flat card holder to easily and securely manipulate the cards.
