Roll seal assembly

Abstract

A roll seal assembly for use on a dry suit for diving and other applications where water-tight sealing of garments is demanded. The seal joins a first tubular body to a second tubular body. The first tubular body has an extension comprising a third tubular body. The second tubular body has an extension comprising a fourth tubular body. The roll seal is formed by connecting the open ends of the third and fourth extensions using a fastener and then rolling the fastened ends over a stiff but pliable band.

1 . A roll seal assembly for joining a first tubular body open end to a second tubular body open end, said roll seal assembly comprises a third tubular body fixed to said first tubular body open end and a fourth tubular body fixed to said second tubular body open end, wherein: (1) said third tubular body comprises: (i.) an outside surface and an inside surface; (ii.) a first open end fixed in a fluid-sealed relationship to the first tubular body open end; (iii.) a second free open end adapted for roll sealing; (iv.) a first band of first fastening means disposed around said
 outside surface of said first open end; (v.) a second band of first fastening means disposed around the outside surface of said second free open end; and wherein, (2.) said fourth tubular body comprises: (i.) an outside surface and an inside surface; (ii.) a first free open end adapted for roll sealing; (iii.) a second open end fixed in said fluid-sealed relationship to the second tubular body open end; (iv.) a first band of second fastening means disposed around said outside surface of said second open end; (v.) a second band of second fastening means disposed around said inside surface of said first free open end; and wherein, (3.) said first band of first fastening means is adapted to join said first band of second fastening means, and wherein, (4.) said second band of first fastening means is adapted to joint said second band of second fastening means.   
     
     
         2 . The roll seal of  claim 1  further comprising a resilient sealing band disposed within the free open end of the third tubular body and fixed to said
 inside surface thereof. 
 
     
     
         3 . The roll seal of  claim 2  wherein the first band of the second fastening means is disposed over the second band of the first fastening means in a press-fit relationship forming a first releasable joint between the free end of the fourth tubular body and the free end of the third tubular body. 
     
     
         4 . The roll seal of  claim 3  wherein said releasable joint is disposed over said sealing band.

         6 . The roll seal of  claim 5  further comprising a second turn of the sealing band towards the first tubular body thereby placing the second band of second fastening means proximate to said first band of first fastening means. 
     
     
         7 . The roll seal of  claim 6  wherein the second band of second fastening means is disposed over the first band of first fastening means in a press-fit relationship forming a second releasable joint between the first tubular body and the second tubular body. 
     
     
         8 . The roll seal of  claim 7  wherein the third tubular body and the fourth tubular body are made from an elastic waterproof material. 
     
     
         9 . The roll seal of  claim 8  wherein the third tubular body and the fourth tubular body are made from one of latex, PVC and silicone. 
     
     
         10 . The roll seal of  claim 9  wherein the first fastening means comprises a plurality of loop fasteners of a hook and loop fastening system. 
     
     
         11 . The roll seal of  claim 10  wherein the second fastening means comprises a plurality of hook fasteners of said hook and loop fastening system. 
     
     
         12 . The roll seal of  claim 11  wherein the first tubular body comprises one of the sleeve, the leg and the neck of a garment. 
     
     
         13 . The roll seal of  claim 12  wherein the second tubular body comprises a garment attachment. 
     
     
         14 . The roll seal of  claim 13  wherein said garment attachment comprises one of a glove, a boot and a hood. 
     
     
         15 . The roll seal of  claim 11  wherein said garment is a dry suit. 
     
     
         16 . The roll seal of  claim 11  wherein the garment is a survival suit. 
     
     
         17 . The roll seal of  claim 11  wherein the garment is a pair of fish waders. 
     
     
         18 . The roll seal of  claim 11  wherein the garment is a dry suit jacket having interchangeable neck and wrist seals. 
     
     
         19 . The roll seal of  claim 10  wherein the first tubular body and the second tubular body comprise a conduit for a non-compressible fluid. 
     
     
         20 . The roll seal of  claim 10  wherein the first tubular body and the second tubular body comprise a conduit for a compressible fluid. 
     
     
         21 . The roll seal of  claim 10  wherein the first tubular body is a tubular container having a first open end and a second closed end. 
     
     
         22 . The roll seal of  claim 21  wherein the second tubular body is a tubular cover for said tubular container, wherein said tubular cover has a first open end for closing over said tubular container first open end and a second closed end.
