Definitions

  • This invention relates to apparel and particularly to all dry suits and garment closures and specifically to a roll seal assembly for joining two pieces of a diving suit together in a water-tight relationship.
  • the roll seal assembly of the present invention permits replacement of seals on dry suits in order to change their size or replace worn out or torn seals.
  • Dry suits are used in a variety of applications including underwater sports such as diving, water surface sports such as windsurfing and cold water survival suits.
  • underwater sports such as diving
  • water surface sports such as windsurfing and cold water survival suits.
  • joints between various portions of the suit are water tight able to retain a water seal under pressure and movement of the wearer.
  • Examples of where such seals may be found on a dry suit include glove and wrist seals, ankle and boot seals and hood seals.
  • a variety of solutions have been proposed.
  • This invention describes a combination pant and boot joined by a first and second corrugated connection on the cuffs of the pant and boot.
  • a seal is not suited to a dry suit used in underwater applications where ambient pressures are much higher. Additionally, the body movement of an underwater diver is different and involves a continuous movement of the legs and feet which may stress the type of seal disclosed by Aldridge et al.
  • a second example is U.S. Pat. No. 7,062,786 “Garment with releasable water-tight seal for neck and limbs” issued to Stinton et al on Jun. 20, 2006. Sinton et al discloses a seal system used in a diving suit around the wrist, ankles and neck comprising a first and second annular interlocking seal members.
  • the Stinton design is similar to the Aldridge design but uses a compression seal.
  • the Stinton seal has disadvantages relating to the ability of the seal to withstand axial forces between the two joined garments.
  • the Stinton seal may pull apart under axial loads. Therefore, there is a continued requirement for a releasable seal for a dry suit or similar garment that is water tight, pressure resistant and resistant to diver motion which may cause axial loads sufficient to pull the seal apart.
  • a roll seal assembly for joining a first tubular body open end to a second tubular body open end comprises a third tubular body fixed to the first tubular body open end and a fourth tubular body fixed to the second tubular body open end.
  • the third tubular body comprises an outside surface and an inside surface, a first open end fixed in a fluid-sealed relationship to the first tubular body open end, a second free open end adapted for roll sealing, a first band of first fastening means disposed around the outside surface of the first open end, a second band of first fastening means disposed around the outside surface of the second free open end.
  • the fourth tubular body comprises an outside surface and an inside surface, a first free open end adapted for roll sealing, a second open end fixed in said fluid-sealed relationship to the second tubular body open end, a first band of second fastening means disposed around the outside surface of the second open end, a second band of second fastening means disposed around the inside surface of the first free open end.
  • the first band of first fastening means is adapted to join the first band of second fastening means.
  • the second band of first fastening means is adapted to join the second band of second fastening means.
  • a sealing band disposed within the free open end of the third tubular body and fixed to the inside surface thereof.
  • 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.
  • the releasable joint is disposed over the sealing band.
  • a first turn of the sealing band is made towards the first tubular body.
  • a second turn of the sealing band is made towards the first tubular body thereby placing the second band of second fastening means proximate to the first band of first fastening means.
  • 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.
  • the third tubular body and the fourth tubular body are made from an elastic waterproof material such as latex, PVC or silicone.
  • the first fastening means and the second fastening means comprise a hook and loop fastening system.
  • the hook and loop system can be replaced by zippers, adhesive tape, magnets and snap fasteners.
  • Another object of the present invention is to provide a seal that is seamless.
  • Yet another object of the present invention is to provide a seal that is pliable and continuous.
  • Still another object of the invention is to provide a seal that can joint two garments together.
  • One advantage of the present invention is that it can be used in other applications such as closures for water-tight bags and for joining conduits that carry compressible or non-compressible fluids.
  • Another advantage of the present invention is that it can be use to join two flexible conduits together such as a hose or ducting.
  • Another advantage of the present invention is that the roll seals can be easily replaced on a garment such as a dry suit if the seals are damaged or if the seals need to be increased in size to improve the fit of the garment.
  • Another advantage of the invention is that the roll seal can be used to replace zipper fasteners used on dry suits.
  • FIG. 1 is a drawing of a diver in a dry suit illustrating potential locations of the roll seals of one embodiment of the present invention.
  • FIG. 2 is a view of a diver's arm with diving mitt and a roll seal of one embodiment of the present invention.
  • FIGS. 3A to 3E shows a sequence of steps used to create a roll seal between two garment pieces.
  • FIG. 4 is a cross section of one embodiment of a roll seal of the present invention.
  • FIG. 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.
  • FIG. 3A and FIG. 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.
  • a 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 FIG. 3C and then a second time as shown in FIG. 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 FIG. 1 .
