Abstract

THE OBJECT OF THE INVENTION CONCERNS A FLEXIBLE AND DEFORMABLE WATERPROOF CLOSING DEVICE. IT IS CONSTITUTED BY A SHAFT CLOSED AT ITS TWO ENDS, AND WHOSE BODY IS SHAPED BY TWO SEPARATE SECTORS 1, 2 CONSTITUTING A HALF CAPACITY EACH CONTAINING A SEALING GASKET 5, 6. THESE TWO SECTORS ASSEMBLED OR SEPARATED BY THE MANEUVER OF TWO ZIPPER CLOSURES 7, 8, 9, 10 ARE CLOSE WITH EQUAL TENSION. IT IS INTENDED FOR EQUIPMENT OF PROTECTIVE CLOTHING, SCAPERS AND MAY APPLY TO ALL INFLATABLE STRUCTURES FOR BOATS, TENTS AND OTHERS.

Description

25010 20

  The subject of the invention relates to a device for closing

  Waterproof and deformable.

  It is intended for the equipment of protective clothing

  and suits can be applied to all inflatable structures for boats, tents and others. In known devices, the closures were sealed along the path of the elements of the zippers and the back of the slider which itself played the role of shutter at the end of the race. This resulted in a precarious seal around the cursor. Moreover the maneuver of the slider was hard because it had to ensure the forced jointing of the two lips to be brought together made up with enough materials

  consistent and hard. Finally, during deformations, the surfaces

have to deviate.

  The device according to the invention eliminates these drawbacks.

  nients and allows for a total and flexible closure with

easy handling.

  It is constituted by a sheath closed at its two ends, and whose body is formed by two separate sectors constituting a half capacity each containing a filling

  sealing. These two sectors assembled or separated by

  Two zippers are brought together with a

equal tension.

  of one of the embodiments of the object of the invention.

  The device, FIG. 1, 2, 3, consists of an oven

  formed by enclosing sectors 1 and 2, whose assem-

  3, 4 retain the seals 5, 6.

  Each edge of the sheath sectors is secured to the elements of zippers 7, 8 and 9, 10 with sliders

outside 11, 12.

  The seals are formed by elements

  cylindrical members 5, 6, in the example given, fixed over the entire length of the sheath formed by a flexible sheet of synthetic resin. This filling capacity can be filled by such a material (expanded foam, liquid or gaseous fluids) as by an integral monobloc element or independent of

sheath.

  These tubes can be glued, welded to the sheath and maintained in their functional position by any appropriate means.

  In order to facilitate the upper closure,

  13, 14 are provided at the upper part of the elements, 6, or 13 ', 14' at the bottom to clear the slider 11, By bringing the edges 9, 10 and 7, 8 closer, the sheath, closed at its ends 17, 18, very strongly squeezes the linings, 6, over their entire length 15. The latter by their continuous contact over a wide range 16 will ensure an absolute seal

along the entire length 15, fig 3.

  It is specified that the seals 5, 6, do not

  are not filled by the filling material at their ends.

  so that their envelopes 5 ', 6' can be assembled together

  with each end of the sheath.

  The sheath, FIG. 3, is connected to the surfaces to be sealed. This flexible and elastic closure retains its tightness.

  whatever the deformations suffered. Sliding closures

  are also protected against wreckage and

  efforts that may be greater than their resistance.

  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents as well as the materials used for their manufacture without changing for this the general design of the invention which has just been described.

Claims (3)

  1 sealing device, flexible and deformable   intended for the equipment of protective clothing, scaphan-   and all inflatable structures consisting of a closed sleeve at the ends (17, 18) whose body is provided with two opposite longitudinal openings (11, 12), and which   one or more longitudinal sealing elements (5, 6).   2 Device according to claim 1, characterized   in that each half sector (1, 2) of the outer sheath   carries on their edges elements (7, 8 and 9, 10) closing   with sliders with sliders (11, 12).   Device according to Claim 1, characterized   in that the or the sealing elements (5, 6) are each constituted by a cylindrical envelope (5 ', 6') filled (all or part) with a compressible elastic material,   a gas or a liquid depending on the applications, or any   monoblock equivalent to this assembly (envelope + fill wise).   4 Device according to claim 1, characterized   the fact that it is possible to connect by welding or   ge two sealing elements (5, 6) on one hand between them, beyond the opening and in their mutual contact surface,   on the other hand in the sheath on an outer peripheral zone.   Device according to Claim 1, characterized   in that spacer linings (13, 14) are posi-   at the upper part of the flexible and elastic linings (5, 6) which by their forced approximation at equal pressure,   form wide jointing areas (16).
