Definitions

  • the invention relates to an eyeglass attachment for protective masks according to the preamble of claim 1.
  • DE-OS 19 35 854 describes such an eyeglass attachment in which the eyeglass frame is held in the window of a respirator mask via resilient wire clips.
  • a support block is attached, which enables the eyeglass frame to be moved both in the vertical and in the horizontal direction. This allows a certain adjustment of the glasses to adapt them to the physiognomic conditions of the mask wearer.
  • the known eyeglass attachment has the disadvantage that the correct setting of the eyeglass frame with respect to height and distance from the eyes of the mask wearer often has to be corrected several times if an optimal adjustment is to be achieved with a protective mask attached.
  • the coordination of two shifting directions with one another is known to be time-consuming and requires several adjustment attempts in which the mask has to be removed and put back on again and again.
  • the reference plane for the eyeglass attachment, the mask window and the distance of the eyeglass frame can always be varied relative to this reference plane, a multiple correction of the eyeglass distance is necessary, if the edge of the mask fits closer to the face when the contact pressure is increased and this dips deeper into the mask.
  • the glasses must move along the bridge of the nose. This necessary displacement is hindered because of the frictional pressure generated, and it can even be omitted, so that the mask wearer feels a disturbing pressure.
  • the situation is similar when the distance between the mask body and the face is increased.
  • the function of the deformable bar is limited to pushing the spectacle frame against the nostrils once it is in contact with the pads. That spring pressure would make it more difficult to slide if the distance from the mask wall to the face area changes.
  • the present invention is therefore based on the task of improving a spectacle attachment for protective masks so that they are securely and captively connected to the mask, are not disruptive or easily removable when not in use, and that the spectacle frame can be moved from the mask wearer in the horizontal direction without further adjustment the correct viewing distance to his eyes.
  • the advantage of the invention lies mainly in the fact that when the protective mask is put on, the face is immersed in the mask and pressed against the spacer, which then moves the spectacle frame until the face of the mask wearer is completely and securely in the sealing lips of the protective mask Ligament is held.
  • a horizontal adjustment of the eyeglass frame is not necessary since the face and in particular the forehead-nose area of the device wearer is now taken as a reference surface for the horizontal distance of the eyeglass frame from the eyes.
  • the distance once it has been established even if the head of the mask wearer moves in a horizontal direction relative to the protective mask or if the eyes are brought more or less close to the lenses by different face shapes of different mask wearers.
  • the web for holding the eyeglass frame with the mask body is formed in one piece, there is no need for the eyeglass attachment to be laboriously buttoned into the mask body. This also prevents accidental slipping or loss.
  • the flexible web is not annoying when not in use.
  • the masks can generally be made with the bridge. Later on, the bridge can be removed by simply cutting off those who are definitely to be used without glasses.
  • the frictional sliding bracket is realized in that two parallel square columns are attached to the web as torsion bars.
  • the spacer which is advantageously also designed as an elastic, foldable eyeglass web, has two correspondingly shaped tabs into which the square pillars are pressed in, the eyeglass web being folded so that the eyeglass lenses are folded together. After the glasses are attached, the glasses open and the eyeglass bridge folds up so that the square columns are rotated and thus ensure that the glasses cannot be moved.
  • this arrangement has the advantage that when the protective mask is folded with the glasses buttoned in, the square pillars are not under a torsional tension and thus show hardly any signs of fatigue during use or aging.
  • the eyeglass attachment according to the invention can be used both with full face masks and with full face masks with an inner mask.
  • the web can be attached in the nose area of the mask in continuation of the mask body, if an inner mask is present, preferably on the top thereof, the spacer being attached at right angles to the web.
  • these parts can also be molded onto the mask body in a mold. If the head of the mask wearer dips into the mask, the spacer becomes a mask window through the face of the mask wearer pressed down so that when the protective mask fits, the spacer rests resiliently against, for example, the forehead or the bridge of the nose of the protective mask wearer.
  • the spacer is non-positively held on the web for vertical displacement and adjustment of the glasses.
  • the section through the protective mask shows the mask body (1) with an inner half mask (2), which has a filter connection (3) and a valve stub (4).
  • the strap (5) is attached to the mask body (1) in the area of the sealing lip (6).
  • a web (7) is formed, from which a spacer (8) extends at right angles.
  • the connection between the web (7) and the spacer (8) represents a sliding bracket (10) which is arranged to be movable along the web (7).
  • the eyeglass attachment is arranged on the half mask (2) in such a way that when the protective mask is attached, the web (7) is bent back so far that the eyeglass lenses (9) lie in line of sight with the mask windows (11). This is shown in Fig. 2. Matching details are provided with the same numbers in the two figures.
  • Fig. 3 the web (7) is shown, which carries a spacer (8) designed as a foldable eyeglass web.
  • the web (7) has two square columns (15) which are encompassed by two square tabs (16), the spectacle lenses (9) being folded together. After unfolding, the spacer (8) lies against the face with its inner surface during use.
