Definitions

  • a mask mask body for a respiratory half-mask the front or side mounted exhalation valve and filter fittings and fastening means for a connected to a harness holder, wherein the filter connection and exhalation valve pieces each having a rigid plastic material surrounded by the soft elastic material of the mask body.
  • Respiratory half-masks are worn in front of a user's face, covering the mouth and nose, to protect against harmful gases, vapors and particles. They consist of a mask body made of soft, elastic material, the shape of the following edge area sealingly rests on the face. In the mask body either two laterally arranged filter connectors and a frontally arranged Ausatemventil laminate or two laterally arranged Ausatemventil stainede and a frontally arranged filter connector are sealingly integrated. On the outside of the mask body consisting of a hard plastic holding device for a brace on the user's head harness is releasably attached. A thick body material mask body has the required rigidity for secure mounting of the filter cartridges and the holding device, but can adapt to the respective face shape insufficient. Although a mask body made of thin material seals better, but can fold under the action of the filter cartridges and the holding device and therefore affect the safety of the user.
  • the U.S. 5,592,937 describes a respirator, in which consisting of a soft elastic material mask body with the filter connection and Ausatemventil foundeden connected stiffening plates made of a hard plastic are involved. Between the opposite side edges of the centrally arranged stiffening plate and the laterally arranged stiffening plates, a joint consisting of the material of the mask body is formed. The mask body is thus sufficiently flexible and yet stiff enough not to be able to fold. In the holding device placed around the mask body, openings are provided which correspond to the openings in the stiffening plates formed by the filter connection and exhalation valve pieces. The handling of this respirator is difficult insofar as a frequent attachment and detachment of the holding device on / from the mask body is expensive and a secure connection between the mask body material and the stiffening plates is not guaranteed.
  • the invention is therefore based on the object to provide a stiffening plates provided mask body made of soft elastic material robust and easy to handle and with high comfort and long life.
  • the basic idea of the invention consists in the integration of a substantially rigid mounting plate in the front region of the mask body consisting of a soft-elastic material.
  • the exhalation valve piece or a filter connection piece is integrated in the mounting plate.
  • An integrally formed on the mounting plate mounting cylinder is used to make a plug connection with the holding device connected to a harness.
  • a formed on the peripheral edge of the mounting plate, surrounded by the mask body material narrow connecting strip is used to make the connection between the mounting plate and the mask body.
  • the mounting plate with the mounting cylinder and formed on these projections for locking and anti-rotation ensure a stable connection between the holding device and the mask body, which can be easily prepared and solved in a simple manner.
  • connection between the mounting plate and the mask body material caused by the connection strip is achieved by openings formed on the edge of the connection strip, which are penetrated by the mask body material and provide a positive connection.
  • a positive connection can also be provided in the laterally arranged stiffening plates in which exhalation valve or filter connecting pieces are integrated.
  • the inventively designed mask body provides a stable easy attachment of the holding device for the harness and ensures a long life and a high level of comfort.
  • the soft elastic part of the mask body consists of a special adhesive containing liquid silicone, so that in addition to the positive connection an improved Adhesive bond with the hard plastic, in particular polyamide or polybutylene terephthalate, existing stiffening plates and the connecting strip is achieved.
  • the fastening cylinder surrounds the exhalation valve piece.
  • the fastening cylinder can also be provided with an internal thread and at the same time serve as a filter connection piece.
  • the lower edge of the stiffening plates, or at least the connection strip formed on the mounting plate, is so far away from the edge of the mask body that a user can move his lower jaw when the mask is applied.
  • the mask body 1 shown in the drawing consists of silicone (liquid silicone) containing special adhesion promoter for chemical combination with polyamide or polybutylene terephthalate.
  • the mask body 1 has two laterally arranged filter connection pieces 2 with bayonet connectors 3 and a centrally arranged, in a mounting plate 4 integrated exhalation valve piece 5.
  • the filter connection pieces 2 and the mounting plate 4 is one of a hard plastic, namely polyamide or Polybutylenterephtalat, existing stiffening plate 6 or - with respect to the mounting plate - a connecting strip 12 integrally connected.
  • the stiffening plates 6 and the connecting strips 12 are completely encased with the silicone of the mask body 1.
  • the connecting strip 12 and the stiffening plates 6 penetrated with silicone breakthroughs 7 are formed so that the existing on both sides of the stiffening plates 6 and the connecting strip 12 silicone layers are connected by webs located in the openings 7 and the silicone form fit in the stiffening plates. 6 or the connection strip 12 is held.
  • the adhesion promoters contained in the liquid silicone furthermore provide an additional adhesive bond with the stiffening plates 6 and the connecting strip 12.
  • the stiffening plates 6 extend partially to close to the edge of the mask body and provide sufficient rigidity and yet the sealing requirements in the edge region sufficient flexibility of the mask body 1 to ensure adequate sealing on the face.
  • the integrally formed on the mounting plate 4 connecting strip 12 has a greater distance from the lower edge of the mask body 1, to allow the user with a respiratory mask applied sufficient movement of the lower jaw.
  • the mounting plate 4 is used for simple and secure releasable attachment of a holding device connected to a harness (each not shown), which in combination with the filter cartridges (not shown) relatively heavy and also exposed during an application significant loads mask body 1 am Face or in the meantime also in a remote from the face, drooping position holds.
  • a fastening cylinder 8 To the mounting plate 4, in which the exhalation valve piece 5 is integrated, a fastening cylinder 8, the upper and lower locking lugs 9 and a Vermosêtsvorsprung 10, integrally formed. At the upper end of the mounting plate 4, a Vermosellessnut 11 is formed. A fixture adapted to the thus formed mounting plate 4 can thus be quickly plugged onto the mounting plate 4 and released from it.
  • the fastening cylinder 8 ensures a secure plug connection and power transmission between the mask body 1 and the holding device.
