Definitions

  • the invention relates to protective clothing such as is worn in hazardous environments to protect the wearer from dangerous fumes and/or liquids.
  • Such protective clothing may comprise a suit which must be worn with gloves, boots and a breathing mask. To obtain a required degree of protection, effective seals must be established between these clothing components and the invention is concerned with the provision of sealing arrangements which are inexpensive to produce and simple to use whilst affording seals of appropriate integrity.
  • US Patent 2994089 describes a protective garment in which a sleeve is received in the gauntlet portion of a mitten which is covered by a dummy cuff attached to the sleeve.
  • the sleeve and cuff have respective elastic bands which grip the user's arm and the unsupported gauntlet portion. The seal afforded-by this arrangement is unreliable and the presence of the dummy cuff on the outside of the sleeve is an encumbrance to the user.
  • the present invention aims to overcome these disadvantages and to provide a reliable glove-to-sleeve seal in protective clothing which is convenient and comfortable in use.
  • Glove-to-sleeve seals according to the invention can be provided simply and cheaply, using components which are easily handled by the user.
  • protective clothing comprising a glove having a gauntlet portion received in the free end portion of a sleeve and an annular sealing member sealing an annular space between the sleeve end portion and the gauntlet portion, in which the annular sealing member is secured to only one of the said portions and forms a seal at its interface with the other portion, at least the one of the surfaces of the sealing member and the said other portion in contact at the interface which is a surface of the member to which the sealing member is not attached being inwardly tapered in the direction outwardly of the sleeve end portion, characterised in that the gauntlet portion is sufficiently stiff for the sealing member to be sealingly compressed in the annular space when the glove is urged outwardly of the sleeve end portion is use.
  • the annular sealing member is advantageously secured to the sleeve end portion.
  • the other one of the surfaces of the sealing member and the said other portion in contact at the interface is inwardly tapered in the direction outwardly of the sleeve end portion.
  • the sealing member comprises an annulus of closed cell material and, advan- tagr J ously, has an inner stiffening annulus covered by the closed cell material.
  • the protective clothing includes an inner sleeve extending inwardly of the sleeve from the annular sealing member to the inner end of the gauntlet portion of the glove, an end portion of the inner sleeve being capable of being turned over to extend within the gauntlet portion.
  • the protective clothing includes an inner glove with a gauntlet portion arranged to secure the or each end portion within the gauntlet portion of the outer glove.
  • the gauntlet portion of the inner glove comprises a further annular reinforcement member which tapers inwardly in the direction outwardly of the sleeve end portion.
  • the or each reinforcement member can be readily collapsed to allow it to be moved outwardly of the sleeve through the sealing member.
  • the protective clothing suit and the related clothing components yet to be described can be made of any suitable liquid and gas impervious sheet material, for example PVC, neoprene or natural rubber, depending on the environment from which protection is required. It is assembled .from appropriately cut panels by bonded seams, which can be reinforced by stitching, and over which sealing strips can be secured by adhesive.
  • suitable liquid and gas impervious sheet material for example PVC, neoprene or natural rubber
  • Figure 1 shows in cross-section the free end portion 21 of a sleeve of the suit.
  • the sleeve portion 21 is constructed so as to taper inwardly towards its free end.
  • the suit is worn with gloves 22 and a seal has to be maintained in use between each of these gloves and the associated sleeve of the suit.
  • a seal is effected by means of a ring 24 the material of which can be a resiliently stretchable flexible closed cell foam material, for example neoprene or rubber, so as to be impervious to liquid and gases.
  • the ring 24 can be of relatively rigid material, for example plastics material, lined over at least its internal face with the resilient material mentioned above, or with other material capable of making a seal.
  • the ring 24 is of circular cylindrical or frusto-conical shape.
  • the glove 22 is provided with a gauntlet portion 25 having secured therein as by adhesive and/or stitching (not shown) a frusto-conical reinforcement member 26 of stiff but resiliently deformable material.
  • the gauntlet portion 25 can but need not be extended beyond the larger diameter end of the member 26 as shown at 28, to be turned inwardly in use and form an elasticated restriction around the wrist of the wearer.
  • the ring 24 is secured either to the gauntlet portion 25 or to the sleeve portion 21 so as to be received by them adjacent the opening of the sleeve portion.
  • the glove 22 can be readily assembled with and disassembled from the sleeve 21 by inward deformation of the member 26 along an axial life so that its effective cross sectional area is less than that of the opening of the sleeve portion 21. In use, outward urging of the glove 22 by the user's hand and arm will tend to compress the ring 24 and so enhance the seal it provides.
  • An effective seal is provided in an economical way in components of protective clothing which are conveniently handled by the user.
  • Figure 2 shows a modified arrangement for effecting a seal between the glove 22 and the sleeve 21.
  • the sleeve 21 is again provided with the ring 24, and the glove 22 again includes within its gauntlet portion 25 the frusto-conical reinforcement member 26.
  • the free end of the inner sleeve 29 extends beyond the larger diameter end of the member 26, so that its end portion 30 can be turned inwardly as shown, in the same way as the end portion 28 of the gauntlet portion 25.
  • the seal is effected as before between the glove 22 and the inner face of the ring 24, but the sealing assembly is locked in place by means of a second hollow frusto-conical member 31, suitably of the same material as the member 26.
  • the member 31 is shaped to be received within the member 26, with the end portions 28 and 30 between the two members.
  • the member 31 is preferably secured within the gauntlet portion 32 of a secondary inner glove 33 for example of thin rubber sheet material, which is received in use within the glove 22, to provide additional protection.
  • Figure 2 arrangement enhances the security of the seal, which can be gas-tight and is consequently suitable for use in a gas-tight suit, fitted with a gas-tight zip fastener.
  • a further member of the same general form as the member 31 can be received within the member 31, in the same way as the member 31 is received within the member 26, the gauntlet portion 32 of the secondary inner glove 33 being then extended beyond the inner end of the member 31 to be folded up to provide an end portion corresponding to the portion 28 of the glove 22.
  • the end portion may be engaged by a further frusto-conical member corresponding to the member 31.
  • This further frusto-conical member can be secured within a tertiary glove if required.
  • sealing arrangements described provide seals which are entirely adequate for a range of conditions under which protective clothing has to be worn, and which are extremely simple and inexpensive to provide.
