Definitions

  • the present invention relates to a mouthpiece for the regulator of an underwater breathing apparatus.
  • the regulator second stage is provided with a mouthpiece made of rubber, or other elastomeric material, formed by a tubular element that ends at one end in means for insertion into the mouth.
  • This tubular element is fitted onto the supply line and fixed to it by suitable clamping means, such as a hoop or suchlike means.
  • the subject of the present invention is therefore a mouthpiece for the regulator of an underwater breathing apparatus, comprising a tubular pipe, for attachment at one end to the supply line of the regulator, and having at the other end means for insertion into the mouth, these being made integrally with the said pipe of elastomeric material, the mouthpiece being characterized in that attached to the said pipe is a stiffener providing stiffening along the axial direction of the said pipe.
  • the said stiffener is preferably elastically compliant along its radial components; in particular it has at least one at least partial discontinuity along a direction parallel to the axis of the said pipe.
  • the said stiffener may comprise one or more elements of relatively stiffer material located on the outer lateral wall of the said pipe, or embedded in it; the stiffener and the tubular pipe preferably being connected to each other by overmoulding the relatively softer material onto the relatively stiffer material.
  • Figure 1 shows a first embodiment of the mouthpiece according to the present invention
  • the number 1 denotes the tubular pipe made of elastomeric material connected to the supply line 10 of a regulator (not shown in the figure) by the clamping means represented by the ring 3.
  • the sleeve 101 of relatively stiffer material On the tubular pipe 1 is the sleeve 101 of relatively stiffer material, which in the portion nearest the line 10 of the regulator has the cutouts 121 that separate the fingers 111 from each other; it is in these cutouts that the elements 201 of the pipe 1 are positioned.
  • the means 2 held in the mouth are formed integrally with the pipe 1.
  • FIG 2 the mouthpiece of Figure 1 is illustrated in an exploded drawing. This view shows more clearly that the elements 201 actually project from the wall of the pipe 1 and fit into the cutouts 121 formed in the sleeve 101. Also visible is the flange 131, which was not shown in Figure 1, running around the perimeter of the sleeve.
  • FIG 3 illustrates a second embodiment of the mouthpiece of the invention, with identical parts being given the same numbers.
  • the tubular pipe 4 of elastomeric material contains internally the stiffener, which consists of a tubular element 104 (depicted in perspective in Figure 4) which has the longitudinal cutouts 114 and 124. Near the outlet edge of the pipe 4, the latter has an annular relief 134 against which the outlet flange of the supply line 10 of the regulator abuts.
  • the sleeve 101 is made in such a way as to give the mouthpiece greater stiffness along its axial component, thus saving the diver from having to make unnecessary efforts to grip the regulator between his or her lips.
  • the sleeve 101 must allow the pipe 1 to be clamped efficiently to the line 10 of the regulator; it is for this purpose that the longitudinal cutouts 121 are formed in the portion of the sleeve nearest the line 10 so as to give the sleeve a certain degree of elastic deformability in its radial components.
  • the pipe and the sleeve 101 are assembled by overmoulding the two materials; in practice, after the sleeve 101 has been produced, it is inserted in the mould of the pipe 1, and the latter is then moulded to the sleeve 101.
  • the elements 201 When inserted into the cutouts 121 of the sleeve, the elements 201 not only give elasticity but also ensure the structural cohesion between the two components of the mouthpiece according to the invention.
  • connection between the pipe and the means for insertion into the mouth on the one hand, and the sleeve on the other, is made still more complete by the flange projecting radially from the end of the sleeve 101 nearest the means 2 for insertion into the mouth, this flange being designed to be embedded in these means at the production stage.
  • the stiffener represented by the tubular element 104 exhibits greater simplicity of construction, which simplifies the production of the mouthpiece according to the invention.
  • This tubular element can be completely embedded in the pipe 4 of elastomeric material, or can project inside or outside of the thickness thereof.
  • the mouthpiece set forth herein adopts a simpler structure and in so doing efficiently solves the problem of the loads which the user has to put up with in gripping the mouthpiece. Also, the mouthpiece according to the invention is more resistant to external stresses and better designed for clamping on the supply line of the regulator.
