Rotatable Interlocking Pin System

Abstract

A rotatable interlocking pin system to secure a plurality of fabrics together. The system includes a decorative first member, a second decorative member, and a coupling pin for rotatably joining the first and second members together to secure the plurality of fabrics. The first end is rotatably and captively received by the first member's shaft hole, while the second end pierces through the fabrics and is frictionally received by the second member's shaft hole. The members and the coupling pin are free to rotate, thus preventing the fabric from being torn, distorted, or severely damaged by the pin system. The first and second members may be constructed of a variety of decorative or simulative appearances creating coordinating or contrasting members.

1 . A rotatable interlocking pin, comprising in combination:
 a first and second member, each having a body defining an outward facing side, an inward facing side, and a shaft hole extending through said inward facing side and terminating at position within said body, said shaft hole having an inner diameter;   a coupling pin having opposed first and second ends, and a shaft extending therebetween, said shaft having a first shaft portion and a second shaft portion, said first and second shaft portions being conjoined at an intermediate location along said shaft, said first shaft portion extending to said first end, and said second shaft portion extending to said second end, said first shaft portion having a first diameter and said second shaft portion having a second diameter, said first diameter of said first shaft portion being less than said second diameter of said second shaft portion;   said first end of said coupling pin being captively receivable by and being freely rotatable about a long axis of said coupling pin within said shaft hole of either of said first and second members; and   said second end of said coupling pin being frictionally receivable by said shaft hole of the opposite member of said first and second members.   
     
     
         2 . The rotatable interlocking pin of  claim 1 , wherein said first end of said coupling pin is enlarged. 
     
     
         3 . The rotatable interlocking pin of  claim 2 , wherein said first end of said coupling pin is conically shaped and tapers from narrow to wide in a direction from said first end to said shaft, and shaft hole of each of said members defining a shoulder narrower than the wide end, thereby preventing withdrawal of said coupling pin from said shaft hole. 
     
     
         4 . The rotatable interlocking pin of  claim 1 , wherein each outward facing side of said body of each of said first and second members has a decorative appearance; and further wherein the decorative appearance of each outward facing side is different from the other. 
     
     
         5 . The rotatable interlocking pin of  claim 1 , wherein said first diameter is less than the inner diameter of said shaft hole, and wherein said second diameter is greater than the inner diameter of said shaft hole. 
     
     
         6 . A system for securing a plurality of fabrics together, the system comprising:
 multiple layers of adjacent fabrics to be secured together;   a first and second member, each having an inward facing side, an inward facing side, and a shaft hole extending through said outward facing side and terminating at position within said body, said shaft hole having an inner diameter;   a cylindrical coupling pin having opposed first and second ends, and a shaft extending therebetween, said shaft having a first shaft portion and a second shaft portion, said first and second shaft portions being conjoined at an intermediate location along said shaft, said first shaft portion extending to said first end, and said second shaft portion extending to said second end, said first shaft portion having a first diameter and said second shaft portion having a second diameter, said first diameter of said first shaft portion being less than said second diameter of said second shaft portion;   said first end of said coupling pin being captively receivable by and being freely rotatable about a long axis of said coupling pin within said shaft hole of either of said first and second members; and   said second end piercing completely through said plurality of layers of adjacent fabrics, and being frictionally received by said shaft hole of the opposite member of said first and second members such that said first and said second members are rotatably connected together.   
     
     
         7 . The system of  claim 6 , wherein each outward facing surface of each of said first and second members has a decorative appearance; and further wherein the decorative appearance of each outward facing surface is different from the other. 
     
     
         8 . The system of  claim 6 , wherein said first and said second members are free from fixed engagement with said plurality layers of adjacent fabrics such that said first and said second members are free to rotate about said plurality of layers of adjacent fabrics. 
     
     
         9 . The system of  claim 6 , wherein said shaft is of a length such that said inward facing sides of each of said first and second members are disposed in a spaced relationship of a distance that is greater than the thickness of said plurality layers of adjacent fabrics.
