Definitions

  • the invention relates to a removable waterproof assembly for boot, or glove, placed at the free end of the corresponding member: leg or sleeve, of a protective garment; it relates more particularly to the assembly of the type in question produced by means of two semi-rigid rings, each arranged at the flexible open free end of the corresponding member.
  • the invention overcomes these drawbacks. It aims at an assembly of the type in question, which is economical, compact, light, and in which the assembly, while ensuring an excellent seal, remains flexible so as not to impede walking, while guaranteeing absolute safety and in place easy.
  • the invention consists in covering the assembly of the two rings fixed respectively to the end of the member and of the boot or glove, by a flexible rollable skirt, integral with the end of the member, which covers and is pressed tightly on the assembly produced by the two semi-rigid rings, so as to ensure good mechanical support and to participate in the sealing of the assembly.
  • the flexible rollable skirt consolidates the mechanical connection of the two semi-rigid rings and completes the tightness of the assembly without compromising flexibility and comfort.
  • the solution according to the invention facilitates installation on the user.
  • the rings and the skirt are made of the same material as the member to which they are intended to be hung, so as to adhere firmly to this member and to give the whole a homogeneous behavior.
  • Figure 1 is a schematic summary representation of a protective suit suit according to the invention.
  • FIG. 2 is a schematic representation in section of the two semi-rigid rings in accordance with the invention, shown assembled in section in FIG. 4.
  • Figure 3 is a schematic summary perspective view of the characteristic cylindrical skirt of the invention.
  • the top (17) of the boot (15) has a semi-rigid ring designated by the general reference (20) for example of chlorosulfonated polyethylene, that is to say an elastomer of the same kind as that constituting the boots (15) or (16).
  • This first monobloc ring (20) injection molded has on its internal face (21) a radial female groove (22) of twenty millimeters in height and three millimeters in depth.
  • This monobloc ring (20) is fixed on the top (17) of the boot (15) by a cylindrical connection (23) vulcanized on (17), forming an integral part of the ring itself (20).
  • this second monobloc leg ring (30) is made of injection-molded butyl rubber, in particular of isoprene butyl rubber, that is to say in the same material as that of the leg (13), to be able to be easily joined by vulcanization.
  • this leg ring (30) comprises a radial male ring (31), intended to be received in the female groove (22) of the first ring (20).
  • This radial ring has for example a height of the order of four millimeters for a thickness of three millimeters in radius.
  • the free end (32) of the ring (30) has a chamfer directed outwards and inclined downwards, so as to facilitate the introduction of the second ring (30) into the first ring (20), which as already said, has an internal diameter slightly smaller than the external diameter of the leg ring (30), so as to ensure good mechanical assembly male (31) / female (32), by playing on the elasticity of the two materials of the two boot rings (20 / leg (30).
  • the boot ring (20) has a bulge (25) in the middle and outside.
  • the assembly also has a cylindrical skirt, designated by the general reference (50) and shown in FIG. 3, also in a semi-rigid flexible material, joined in particular by vulcanization, on the bottom of the leg (13), for example at (51), just above the leg ring (30).
  • This flexible cylindrical skirt (50) which can be rolled up on itself, is intended to cover and then come to be pressed against the assembly produced by the two leg (30) / boot (20) rings engaged one inside the other.
  • the free end (52) of the ring has a solid O-ring (53), intended to facilitate the operation of placing (or removing) the skirt (50) on the assembly of the two semi-rigid rings (20,30).
  • this skirt which may be made of vulcanized butyl rubber, has a height of eighty millimeters, a thickness of one millimeter and the rod a diameter of five millimeters.
  • the assembly is carried out as follows.
  • the operator After having put on the suit, the operator introduces the leg ring (30) into the boot ring (20) by varying the elasticity of the materials, until the radial ring (31) is perfectly in place in the groove (22). It then unrolls the skirt (50) on the assembly until the solid rod (53) comes to bear on the bulge (25). Thanks to its elasticity, the cylindrical skirt (50) presses perfectly on the assembly of the two rings, giving it good hold and excellent sealing. As the rod (53) rests on the bulge (25), it is difficult to tear off the skirt unexpectedly, for example while walking.
  • the assembly is relatively flexible and therefore does not interfere with walking.
  • connection thus produced is therefore mechanically simple and perfectly sealed. It is economical to make.
  • the assembly obtained is light, flexible and therefore does not hinder walking.
  • this type of assembly can be used for any protective clothing, in particular suit and suit, more particularly for NBC protection (nuclear, biological, chemical) and for any protective clothing where excellent sealing is sought. .
