  • Figure 4 is a cross section of one embodiment of a roll seal of the present invention.
  • Figure 5 is a view of a dry suit having an entry portal sealed by one embodiment of the present invention.
  • the invention is best explained with reference to a single example of its application. Therefore, the example used is a dry suit garment and the attachment of a glove or boot to the dry suit. As previously noted and claimed herein, the invention can be used to close and seal in a water-tight relationship a variety of tubular bodies.
  • FIG. 1 there is shown a diver 10 wearing a dry suit 12.
  • the dry suit generally has connecting garments which require sealing at the neck 14, wrist 16 and ankle 18. These garments can comprise gloves, mitts, boots and hoods.
  • FIG 2 there is shown, as an example, the sleeve of a dry suit 12 connected to a mitt at the wrist 16 using the roll seal 22 of the present invention.
  • Figure 3A and Figure 3B illustrate how a wrist roll seal 22 is assembled.
  • FIG. 3A there is shown the roll seal disassembled into a cuff portion 31 and a sleeve portion 33.
  • the sleeve portion 33 is fixed to the end of arm 35 of the diving garment 12 by water proof stitching.
  • the attachment point would be inside the distal end of sleeve 35 around the base 37 of the sleeve portion 33 of the roll seal assembly 22.
  • the seal can be replaced to suit a desired size change, that is, a larger or smaller seal.
  • the sleeve portion 33 comprises a first band of fastening hooks 34 disposed around the outside of the sleeve portion 33 just above the base 37 of the sleeve portion where it joins the end of the arm 35 of the diving garment 12.
  • a second band of fastening hooks 40 is disposed around the outside of the sleeve portion at the distal end 42 of the sleeve portion 33.
  • the sealing band is of necessity harder than the material used for the rolled sections as described below in order to form a base for the rolled seal.
  • Sealing band 30 retains the distal end 42 of the sleeve portion 33 open and in a generally circular shape and facilitates rolling the seal as more fully explained below.
  • the sealing band must have some stiffness but remain flexible as well.
  • the sleeve 35 of the dry suit 12 may terminate in a latex (or PVC or silicone) sleeve extension 47.
  • An extended latex section 28 can be attached by stitching 36 so that there is sufficient rolling material between the first band of fastening hooks 34 and the second band of fastening hooks 40.
  • the cuff portion 31 comprises a wrist sealing section 26 which comprises a section of latex shaped in the form of a truncated cone. The distal end 44 of the wrist sealing section 26 fits around the wrist in a water tight compression seal.
  • first band of loop fasteners 32 Around the base of the wrist sealing section 26 there is a first band of loop fasteners 32.
  • a second section of latex 37 is located between the first band of loop fasteners 32 and the base 41 of the cuff portion.
  • a second band of loop fasteners 39 is disposed on the inside surface of the base 41 of the cuff portion 31. It is to be understood that zipper fasteners, can be used instead of hook and loop fasteners.
  • the first step in creating the roll seal is to join the cuff portion 31 to the sleeve portion 33 of the roll seal assembly 22.
  • the band of fastening loops 39 is brought into overlapping contact with the second band of fastening hooks 40.
  • the hooks and loops interact to form a joint at line 46 to hold the two portions together in a stable configuration while the seal is rolled into formation.
  • Sealing band 30 is disposed beneath the hook and loop joint to prevent the now joined first and second latex extensions from collapsing.
  • the second step in forming the roll seal is to roll the first band of loop fasteners 32 towards the sleeve 35.
  • the sealing band 30 is rolled a first time over second latex section 37 as shown in Figure 3C and then a second time as shown in Figure 3D.
  • the loop and hook fastener will absorb any axial stress between the sleeve 12 of the dry suit and the seal assembly 22.
  • the loop and hook fasteners can be replaced by adhesive tape, a zipper fastener, magnetic fasteners and snap fasteners.
  • a boot, glove or hood can be attached to the cuff portion 31 of the seal assembly to provide a water-tight seal between the dry suit sleeve and the boot, glove or hood.
  • FIG. 4 there is shown a cross-section of the completed roll seal assembly 22 which forms a water-tight, seamless and continuous seal between the sleeve 35 of the dry suit 12 and the garment attached over the wrist sealing section 26.
  • the resilient sealing band 30 forms the core of the seal.
  • the hook and loop fastener combinations (39 and 40) and (32 and 34) resist any axial forces between the sleeve of the dry suit and the attached garment.
  • the rolled latex (or PVC or silicone) extension 28 wrapped around the sealing band provides a water-tight seal.
  • FIG. 5 there is shown a view of a dry suit having an entry portal 90 that is sealed by a roll seal 92.
  • the roll seal could replace the use of a dry zipper seal as shown in Figure 1.
