Definitions

  • the present invention relates to a device for attaching a respiratory mask to a protective helmet.
  • This device making it possible to adapt, when desired, a removable breathing mask to a protective helmet, belongs to the type of those composed of two lateral mooring arms, each consisting of two elements mounted to slide one relative to the 'other and associated with an internal spring tending to make them penetrate one into the other, one of the elements of each mooring arm being articulated by its anterior end on one side of the respiratory mask, while the other element of said arm is provided, at its rear end, with a hook intended to cooperate with a hooking notch located on one side of the cap of the helmet.
  • the telescopic structure of the mooring arms, and their internal spring, ensure the application of the respiratory mask on the face of the user, with a good seal around the periphery of the mask, without making any preliminary adjustment of arm length.
  • the invention provides simple means which make it possible to modify the tension of each mooring arm and which, in particular, allow a readjustment of this tension during use, without it being necessary. remove the mask.
  • the interior spring of each mooring arm is a helical spring compressed between a bearing face belonging to one of the elements of the arm and a stop belonging to a movable member in the longitudinal direction of the arm, a retaining means being provided on this arm for locking the movable member in any position corresponding to a desired compression of the spring, or for releasing said movable member, thereby allowing adjustment or readjustment of the compression of the spring.
  • the aforementioned movable member is a movable rod, around which the helical spring is wound, the movable rod being provided with a flange for supporting the anterior end of the spring , and this movable rod extending in front of the flange so as to protrude outside the arm.
  • the rear end of the helical spring is supported on a folded tab, provided at the end of an element of each mooring arm, this folded tab having a hole through which the movable rod passes.
  • the retaining means is produced in the form of a pivoting cleat carried by one of the elements of each mooring arm, this cleat having an external part for its operation, and an inner part cooperating with the movable rod to block it in any desired position.
  • the pivoting cleat of angled shape, crosses with a certain clearance a slot made in one of the elements of each mooring arm, the interior part of this cleat being pierced with a hole traversed by the movable rod.
  • the two elements of each mooring arm are both made from cut and folded metal plates.
  • the two elements can in particular be folded so as to each have a "U" section with inclined wings, giving the entire arm a section of trapezoidal shape, the profiles of the two elements fitting into one another to provide sliding guidance.
  • One thus obtains, by simple and inexpensive means, a very resistant complete arm structure, ensuring good protection of the mechanism located inside, and requiring a minimum number of parts.
  • the hook of each mooring arm can be simply formed by a folded portion of the rear end of one of the elements of this arm.
  • the anterior end of the other element also comprises a folded part, on which a clevis is articulated asymmetrically, itself articulated on one side of the respiratory mask; thus, a simple reversal of the yoke makes it possible to mount the same mooring arm either on the right side or on the left side of the respiratory mask, which further contributes to the simplicity, the economy and the convenience of use. of the device.
  • the structure of the mooring arms allows them to be disassembled and reassembled quickly, without tools, thus making maintenance very easy.
  • FIG. 1 and also in FIGS. 5 and 6, there is shown a protective helmet, for example intended for firefighters, which comprises a rigid outer cap 1, inside which is a non-visible deformable cap, allowing adaptation of the helmet on the user's head.
  • This protective helmet is designed to be able to be used at the same time as a respiratory mask 2, covering the entire face of the user and comprising a goggle 3.
  • the cap 1 of the helmet externally comprises, on its sides, two hooking notches 4, one of which is visible in the drawing, the other being symmetrical with the first.
  • the respiratory mask 2 is provided with two lateral mooring arms 5, also arranged symmetrically.
  • each of the mooring arms 5 is more particularly shown in FIGS. 2 to 4.
  • the arm 5 is formed mainly of two elements 6 and 7 of "U" section with inclined wings, one of which 6 is slidably mounted inside the other 7, which gives the arm 5 a telescopic structure, with a trapezoidal section.
  • the two elements 6 and 7 of the arm 5 can each be made in one piece, from a sheet metal plate suitably cut and then folded.
  • the outer element 7 of the arm. 5 has, at its front end, a folded tab 8 on which is articulated, around a substantially horizontal axis 9, a small yoke 10.
  • This yoke 10 is itself articulated, according to a axis 11 perpendicular to the previous one, on one side of the breathing mask 2, near the hoop 12 of the telescope 3. It should be noted that the pivoting mounting of the yoke 10 on the folded tab 8 allows, by turning this yoke 10, d 'use the same mooring arm 5 indifferently on the right side and on the left side, despite the asymmetry of this yoke 10 with respect to its axis of articulation 9.
  • the inner element 6 of the arm 5 comprises, at its rear end, a folded part 13 which forms a hook, intended to cooperate with one of the hooking notches 4 of the cap 1 of the helmet.
  • the hook 13 is itself provided with two opposite notches 14 increasing the security of the attachment, avoiding any separation of the notches 4 even in the event of oblique traction or impact.
  • An elastic connection between the two elements 6 and 7 of each mooring arm 5 is produced by means of a helical spring 15 working in compression, which is housed inside the arm 5, and wound around a movable rod 16.
  • the rear end of the spring 15 is supported on a lug 17 bent at a right angle, provided at the rear end of the external element 7 of the arm 5, the lug 17 comprising a central hole 18 through which the rod 16 passes.
  • the front end of the spring 15 is supported on a flange 19 of the rod 16. This rod 16 extends, in front of the flange 19, so as to protrude outside the arm 5.
  • a slot 20, formed towards the front of the internal element 6 of the arm 5, is crossed with a certain play by an elbow metal cleat 21, which has an external branch 22 forming an operating lever, and an internal branch 23 pierced a hole 24 through which the rod 16 passes, this second branch being capable of ensuring blocking. of the rod 16 in any position.
  • FIG. 3 shows the arm 5 in the retracted state, when it is not hung on the cap of the helmet.
  • the inner element 6 of the arm 5 is pulled out of the outer element 7, until the arm 5 takes a sufficient length to allow the engagement of the hook 13 on the corresponding notch 4 of the cap 1 of the helmet.
  • the spring 15 is then compressed more, and this spring 15, tending to bring the inner element 6 into the outer element 7, ensures the application of the respiratory mask 2 on the face of use.
  • the device described above also makes it possible to prestress the spring 15 as soon as the respiratory mask 2 is put in place. This device also makes it possible, conversely, to reduce the compression of the spring 15, without leaving the mask 2, the branch 23 of the cleat 21 ensuring "self-locking" of the movable rod 16 in any desired position.
