Double clamp card attachment

Abstract

The present invention relates to a card display device that includes two clips rotatably attached. A rivet connects the two clips and allows the clips to rotate with respect to each other. The design of one of the two clips allows it to grasp a card while the other clip grasps a user's clothing. In some embodiments, a suspender style clip serves as the card attachment. In other embodiments, a clothespin type clip serves as the card attachment. In some embodiments the first clip and second clip have only three separate jaws. The card attachment clip may include plastic or rubber gripping pads that aid in providing a secure grip.

What is claimed is:  
     
         1 . A card display device comprising a first clip for retaining a card, a second clip for attaching to a user's clothing without making a hole in the user's clothing, said clips being attached to each other.  
     
     
         2 . The card display device of  claim 1  in which the first and second clips are pivotally attached.  
     
     
         3 . The card display device of  claim 2  including a rivet attaching the first and second clips.  
     
     
         4 . The card display device of  claim 1  in which the first clip is a cam-and-lever type clip.  
     
     
         5 . The card display device of  claim 1  in which the first clip includes two jaws, a hinge, a spring, and two gripping surfaces.  
     
     
         6 . The card display device of  claim 1  in which said first clip includes a first and second jaw; said second clip includes a third and forth jaw; where said second jaw of said first clip and said third jaw of said second clip are a opposite sides of one piece.  
     
     
         7 . The card display device of  claim 1  in which the first clip comprises a pair of jaws pivotally mounted on a hinge axis, each jaw having a gripping surface, a spring urging the jaws into an open position in which said surfaces are positioned to permit insertion of a card, a side wall positioned between said axis and said surfaces, where said surfaces are substantially parallel with respect to one another and said side wall which limits insertion of a card into the attachment.  
     
     
         8 . The card display device of  claim 7  in which the side wall has a length of approximately half of the distance between the hinge axis and a distal tip of the gripping surfaces.  
     
     
         9 . The card display device of  claim 7  in which the ratio of the length of the side wall to the length of the gripping surfaces is approximately two to one.  
     
     
         10 . The card display device of  claim 7  in which the side wall extends away from the hinge pin at least ¼ inch in the direction of the gripping surfaces.  
     
     
         11 . The card display device of  claim 7  in which the side wall prevents a card from being inserted within ¼ inch of the hinge pin.  
     
     
         12 . The card display device of  claim 7  in which a card may be inserted into the attachment no more than ¼ inch.  
     
     
         13 . The card display device of  claim 7  further comprising a closing lever in which said lever locks said jaws in a closed position.  
     
     
         14 . The card display device of  claim 7  in which the jaws in the closed position cover at most approximately ¼ inch by ⅜ inch of a card held between the jaws.  
     
     
         15 . The card display device of  claim 7  in which the spring comprises a leaf spring.  
     
     
         16 . The card display device of  claim 7  in which the gripping surfaces are made of a soft plastic.  
     
     
         17 . The card display device of  claim 7  in which the gripping surface is made from polyvinyl chloride.  
     
     
         18 . The card display device of  claim 17  in which the gripping surface is made from polyvinyl chloride with a Shore A hardness of  65 .  
     
     
         19 . The card display device of  claim 7  in which the gripping surface is made of rubber.  
     
     
         20 . A card display device comprising a first clip for retaining a card, a second clip connected to the first clip, the second clip including a first jaw and a second jaw for gripping a user's clothing.  
     
     
         21 . The card display device of  claim 20  in which the first and second clips are pivotally connected.  
     
     
         22 . The card display device of  claim 21  including a rivet connecting the first and second clips.  
     
     
         23 . The card display device of  claim 20  in which the first clip is a cam-and-lever type clip.  
     
     
         24 . The card display device of  claim 20  in which the first clip includes two jaws, a hinge, a spring, and two gripping surfaces.  
     
     
         25 . The card display device of  claim 20  in which the first clip includes a pair of jaws pivotally mounted on a hinge axis, each jaw having a gripping surface, a spring urging the jaws into an open position in which said surfaces are positioned to permit insertion of a card, a closing device that selectably holds the jaws in a closed position.  
     
     
         26 . The card display device of  claim 25  in which the closing device includes a lever and cam where the cam engages the spring move the jaws to a closed position.
