Definitions

  • the invention relates a closure for zipper ends of at least one liquid or gas tight zipper.
  • the zipper or zippers is/are used for connecting at least two sheet material portions so that they can be taken apart if wanted.
  • the closure comprises two plates capable to cover the zipper ends, when said sheet material portions with the zipper(s) are between said plates, a sealing ring of an elastomeric material, and a clamp for tightening said plates towards each other, whereupon the sealing ring seals against the sheet material portions and said zipper(s)
  • Patent publication US 2,753,609 discloses a double slide fastener sealing closure, which include a reinforcing member or an insert of metal or other resilient material positioned in the extremity of the sealing strip for the nest thereof.
  • the nest receives the diamond of the slider, whereupon the outer periphery of the diamond has an improved fluid-tight contact with the nest, while the angular tips of the nest spring back towards each other behind the diamond.
  • Patent publication US 4,604,775 discloses an alternative fluid-tight sealing slide fastener, which includes a pair of rows of coupling elements mounted respectively on inner opposite edges of a stringer tape, an elastomeric top stop mounted on the stringer tape around a terminal opening at ends of the rows of coupling elements, and a slider for taking the rows of coupling elements into and out of intermeshing engagement.
  • the slider includes a slider body having a pair of upper and lower plates interconnected by a diamond, a presser having a plurality of pins extending through the upper plate, and a screw having a threaded shank threaded in a cylindrical body on the upper plate of the slider body and a head acting on the presser.
  • Patent publication US 4,782,563 discloses an end stop for slide fasteners, which include a rectangular block molded on a portion of folded inner longitudinal tape edges including a plurality of coupling elements mounted thereon, and an integral peripheral seat attached to opposed stringer tapes.
  • the block has an end wall engageable with the slider, and a recess extending in the end wall and defined by and between the block and a portion of the peripheral seat.
  • the portion of the peripheral seat terminates slightly short of the end wall of the block with the result that the slider is brought into abutment with the block without interference with the peripheral seat.
  • the recess serves to absorb shock force which would otherwise be transmitted directly to the peripheral seat when the slider impinges on the block.
  • Patent publication US 5,231,736 discloses a cover for the ends of at least one zipper in combination with at least one zipper having ends, comprising: a lower plate and an upper plate between which the ends of at least one zipper may be clamped; a seal disposed between said lower plate and said upper plate said seal being made of an elastomeric material; disengageable connecting means for securing said upper plate to said lower plate, which permits said cover to be completely disassembled and reassembled, said connecting means comprising a screw and a sleeve, and said sleeve being formed as one piece with said lower plate; wherein the ends of the at least one zipper have chains that extend toward each other; said at least one zipper having a zipper slide; wherein said cover which extends toward the zipper chains, is adapted for bridging over and sealing off in a gas tight or liquid tight manner, gaps between the zipper chains that are dimensioned to be large enough to allow the zipper slide to be inserted or removed; by said upper plate, lower plate and said screw being capable of completely covering on
  • This cover construction for zipper ends provide a sealing effect only if very high forces can be attained with the disengageable connecting means for securing said upper plate to said lower plate.
  • zippers with interlocking teeth having upper and/or lower surfaces or surface sections in level(s) different from the tape surfaces and/or above mentioned sheet material surfaces are problematic when sealing is aimed using this cover construction.
  • a closure for zipper ends that are terminals of at least one liquid or gas tight zipper, said at least one zipper comprising two chains each adapted to interlock with some other chain by use of a slider, and said chains of the at least one zipper being fixed to at least two sheet material portions for detachable connection thereof, whereupon there is a gap between said ends;
  • said closure comprising: a first plate and a second plate having lengths and widths to cover said zipper ends, when said sheet material portions with said chains of zipper(s) in interlocked state are positioned between said first and second plate; a sealing ring of an elastomeric material disposed between said first and second plate; a clamp for tightening said first plate and said second plate towards each other, said sealing ring against said sheet material portions and said chains of zipper(s).
  • Said sealing ring has a seal length and a seal width to surround said zipper ends, said sealing ring comprising: at least a continuous inner loop-ridge, and at least a continuous outer loop-ridge both extending along said sealing ring; at least first join-ridges, each of which bridging two points of said outer loop-ridge; and a first groove between said inner loop-ridge and said outer loop-ridge together with said first join-ridges, and second grooves between said first join-ridges and said outer loop-ridge; whereupon said sealing ring is seated on said first plate in a position, where said loop-ridges together with said join-ridges are to press at least against said chains of zipper(s), and said loop-ridges within said seal length are to press against said sheet material portions.
  • said ridges of the sealing ring have a height from bottoms of the grooves and a width between neighboring bottoms of the grooves, whereupon the ratio of said height to said width is between 1:0.7 and 1:2; and/or said ridges with substantially linear sides in cross-section thereof have an acute angle at least 45° and at maximum 135°, or at least 60° and at maximum 120°, or between 70° and 110°. This dimensioning prohibits the ridges to fall over or buckle under tightening of the closure, which otherwise could be possible because of the high elasticity of the sealing material.
  • said elastomeric material of the sealing ring has a hardness at least 5 Shore A and at maximum 30 Shore A, or at least 10 Shore A and at maximum 20 Shore A. Accordingly, the material of the sealing ring has very high elasticity, which provide effective sealing of the zipper chains also in direction of the zippers.
  • chains of the zipper(s) having a chain module the breadths of at least the second and/or fourth grooves are larger than said chain module, but deviates from value attained by multiplying said chain module by an integer. Under these circumstances at least one of the ridges is always in a proper position to make a good seal against the zipper chains.
  • Figure 2 shows a combination of two sheet material portions 8a and 8b, which are attached to each other by using either one zipper 9 or two zippers 9.
  • the sheet material portions can be e.g. clothing parts, like water tight or air tight parts of suits or garments, or any other parts of flexible material, like water tight or air tight sections of tents, tarpaulins etc. It shall be understood there can be more than two sheet material portions, and more than two zippers, which are attached to each other so that the portions can be connected to form a continuous product and disconnected whereupon the portions are totally or at least partly off.
  • These at least two sheet material portions 8a, 8b are preferably of a flexible, liquid or gas tight laminate having one or several textile layers, but the sheet material might have also other known or new structure, which provides the necessary degree of tightness for each application or use.
  • the zipper or zippers 9 are also liquid tight or gas tight and have ends 7a, 7b, i.e. terminals, arranged close to each other so that there is a gap Lg between the ends.
  • the water tight or gas tight zipper 9 extends around the suit from the start end 7b of the zipper to the stop end 7a of the zipper, whereupon the user of the suit can dress and undress the suit when the zipper is open, and the suit is tight when the zipper with the closure according to the invention is closed.
  • the sheet material portions 8a, 8b have a discontinuation 14 or cut in the area of said gap Lg extending between the ends 7a, 7b of the zipper(s), the sheet material portions can be total separated from each other.
  • the zipper or zippers comprise two chains 9a and 9b each adapted to interlock with some other chain by use of a slider 13, and the chains 9a, 9b of the at least one zipper is fixed to the at least two sheet material portions 8a and 8b for detachable connection thereof.
  • the zipper(s) 9 can be any known or new construction having good enough tightness properties, high enough strength properties and required use properties, so that the zipper(s) are not explained in detail.
  • Their fixing to the sheet material portions can be made using any known or new material(s) and method, which are not explained in detail.
  • the zipper or zippers come to the terminal area, i.e. area between and around the ends 7a, 7b in directions Z1, Z2 parallel to each other, but they can come also in deviating directions or curved route, i.e. non-parallel direction(s) Z1, Z2, shown by phantom line only in the figures.
  • the zipper or zippers come to the terminal area, i.e. area between and around the ends 7a, 7b in directions Z1, Z2 parallel to each other, but they can come also in deviating directions or curved route, i.e. non-parallel direction(s) Z1, Z2, shown by phantom line only in the figures.
  • the zippers come in deviating or curved direction.
  • the closure 1 for sealing the terminal area between and around the zipper ends comprises a first plate 11 and a second plate 12 having lengths L1, L2 and widths W1, W2 to cover said zipper ends 7a, 7b, when the chains 9a, 9b of zipper(s) 9 fixed to the sheet material portions 8a, 8b are in interlocked state, i.e. closed state, and the zipper(s) with their ends together with those parts of the sheet material portions that surround zipper ends are positioned between said first and second plate.
  • the closure 1 also comprise a sealing of an elastomeric material disposed between said first and second plate, and a clamp 10 for tightening the first plate 11 and the second plate 12 towards each other, whereupon the sealing is pressed against the sheet material portions 8a, 8b and the chains 9a, 9b of zipper(s).
  • the sealing is a sealing ring 2 which has a seal length L4 and a seal width W4, more precisely the inner length and inner width of the sealing ring 2, which seal length and seal width are great enough so that the sealing ring surround said zipper ends, but not run on top of them. With these dimensions the sealing ring sets against the interlocked chains 9a, 9b of the zipper(s) and the outer surface of the sheet material portions 8a, 8b.
