Definitions

  • the invention relates to a respiratory half mask comprising a mask body equipped with front or side filters, a headband support with two sidebands extending therefrom and a band guide element fixed to the mask body for displacing the mask body along the sidebands from a use position into one includes the face releasing position.
  • Respiratory half-masks are used to cover the user's mouth and nose with a mask body formed with side filters or a front filter to protect the mask wearer from airborne pollutants and at least one exhalation valve.
  • the half mask is held by means of a bandage connected thereto, consisting of side bands connected to a head support, on the head of the user.
  • the harness and its connection to the mask body should be designed so that the respirator half-mask can be easily and quickly applied and removed or adjusted and beyond reliably sealing and with high comfort, even under the aspect of heavy filter elements and a high physical stress of the user, is held on the face of the mask wearer.
  • a respirator half-mask with a tape guide member attached to the mask body in which the two sidebands attached to a head support are each guided in an upper guide and a lower guide and are passed crossing from the upper guide to the obliquely opposite lower guide.
  • the four guides form an advantageous four-point mount of the mask body on the user's face.
  • the mask body can be displaced from the position covering a mouth and nose of the user to a position lying below the face or also in the opposite direction along the sidebands guided in the upper and lower guides. This means that the half mask can be put on or taken off relatively quickly and in a simple manner, without having to remove a protective helmet worn over the head support.
  • the secure fit of the mask body and the reliable seal on the face are limited insofar as the mask body slip due to the weight caused by the filter and high physical stress of the user, especially in conjunction with between the mask body and face moisture forming on the face can and thus a reliable seal is not guaranteed.
  • the sidebands adjustably mounted on the head support must be tensioned. The loosely suspended from the head support, intended for tightening the respirator half mask to the user's face ends of the sidebands are perceived by the user as disturbing.
  • One in the EP 0 808 641 B1 described respirator half mask has on the two outer sides in each case a tape guide element for each one connected to a head support sideband, the free ends of which have a closure element to connect the two ends behind the head can.
  • the two tape guide elements have an elongated, arcuate slot in which the respective sideband can slide and in which it assumes the curved structure of the slot to frictionally engage the tape guide element but still being slidably movable.
  • the half mask can be adjusted by overcoming the frictional forces from a position adjacent to the face in a nose and mouth releasing position below the face. The frictional forces are intended to prevent an automatic slippage of the half mask from the face.
  • a respirator half-mask which also permits rapid adjustment from a mouth and nose sealingly covering position to a face-releasing, drooping position.
  • To the Mask body is a tape guide member releasably attached to the two lower connection points each a length-adjustable neck band is attached, the free ends are connected to each other behind the neck of the user.
  • Two side straps connected to a head support and running in lateral guides are attached to the lower edge of a locking flap pivotally connected to the strap guide member at the opposite edge. In the lowered, locked on the mask body position of the mask body is located on the face of the user. The sidebands can still be tightened on the headrest.
  • the two neck bands are connected behind the neck and can also be re-tensioned. Swinging up the locking flap lengthens the length of the sidebands so that the respirator half mask can be removed from the face or - with the neck bands underneath the face suspended from the head support.
  • This respirator half mask is disadvantageous, as well as the side bands neck bands must be provided and each must be tightened when creating the mask.
  • the locking flap can easily solve, so that the respiratory protection is not guaranteed safe.
  • the invention has the object of providing a respiratory half mask of the type mentioned in such a way that a simple, quick donning and removal of the mask, a high level of comfort and a safe respiratory protection are guaranteed.
  • the basic idea of the invention consists in a respiratory half mask with a tape guide part provided on the mask body for adjusting the mask body along the sidebands, in that a movable or adjustable clamping element is attached to the tape guide part in order to move the sidebands by actuating the clamping element in the mouth and nose to clamp the covering position of the mask body to the tape guide member and thereby fix the mask body in the use position.
  • a movable or adjustable clamping element is attached to the tape guide part in order to move the sidebands by actuating the clamping element in the mouth and nose to clamp the covering position of the mask body to the tape guide member and thereby fix the mask body in the use position.
  • the downwardly protruding from the tape guide part ends of the sidebands behind the neck of the user are connected together, so that the half mask at four connection points, namely two upper tape entry points and two lower tape exit points of the two - a single belt loop forming - sidebands on the tape guide part, reliably sealing held on the user's face.
  • band friction webs are formed in the band guide part, with the aid of which the band guide part can be fixed to the side bands in a position corresponding to the position of use of the mask body.
  • the tape guide part comprises two of its outer sides to the center extending upper tape guide channels and two of these preferably at an acute angle obliquely downwardly extending lower tape guide channels.
  • the tape guide between the successive, each outside and inside of the tape guide part formed band guide channels via a Bandumlenkkante on which attack the clamping element and can fix the tape guide part with the mask body on the side bands.
  • the running on the outer surface of the tape guide part upper band guide channels have at the outer, the Bandumlenkkante opposite end each having a guide slot which defines the upper attachment point of the respective sideband, while the lower attachment points are formed by the tape outlet opening from the inside - lower - band guide channels.
  • the inner, lower band guide channels are each bounded by a cover plate formed by the tape guide member and an integrally formed on the tape guide member mounting cylinder.
  • the two Bandumlenkkanten are arranged opposite each other at a distance and form a clamping opening, in which a single clamping element can be moved to clamp both sidebands simultaneously at the respective Bandumlenkkante.
  • the clamping element is a pivotally mounted on the tape guide part clamping lever, which is adapted in length and width to the size of the clamping opening.
  • clamping grooves are formed, which engage in the clamping position on the guided around the rounded Bandumlenkkante sideband and cause a locking of the clamping lever and a secure jamming of the sidebands.
  • the clamping lever is designed as a pivotable about a rotation axis plate, in the side edge surfaces of the clamping grooves are formed and on the upper side of a handle for actuating the clamping lever is formed.
  • the above-mentioned, integrally connected to the tape guide part, serving as a tape guide element mounting cylinder is provided with locking elements and attachable to a mounted on the mask body connecting cylinder and can be locked with this.
  • the terminal cylinder surrounds an exhalation valve integrated into the mask body, the outwardly facing open side of the mounting cylinder is covered with a protective grid.
  • the connection cylinder can also be designed for attachment of a front filter. In this case, of course, the protective grid is missing.
  • two recessed gripping recesses are formed in the outer surface of the tape guide part, which allow easy handling of the respiratory half mask when creating or removing the face.
  • the respirator half-mask comprises a mask body 1 covering the face of a user in the area of the mouth and the nose, a detachably fastened on the mask body 1 Tape guide member 2 and a band consisting of a head support 3 and two side straps 4 attached thereto for holding the respirator half mask in a use position on the face or in a lowered or hanging down position below the face.
  • the mask is removed from the face without removing the protective helmet, but can be quickly re-applied if necessary.
  • a connecting cylinder 5 is provided, the - only in accordance with the in Fig. 4 illustrated embodiment - also for releasable attachment of a respirator front filter (not shown) is used.
  • two lateral exhalation valve seats 6 are integrated into the mask body 1.
  • respirator half-masks with two side filter ports 7 of a centrally formed in the mask body 1 exhalation valve (not shown) surrounding the connecting cylinder is not visible.
  • the sidebands 4 connecting means 8, 9 are mounted in order to connect the adjustable in a desired length elastic sidebands 4 behind the head or neck of the user to a single band loop (single-loop).
  • the two side bands 4 are guided in the tape guide part 2 attached to the mask body 1 for applying and removing the mask or held in the use position.
  • the fastening of the tape guide part 2 takes place with the aid of an integrally formed on this fastening cylinder 10, which is plugged onto the connecting cylinder 5 on the mask body 1 and on integrally formed locking means can be latched thereto ( Fig. 4 ).
  • the connecting cylinder (not shown) a centrally formed in the mask body 1 exhalation valve (not shown) surrounds
  • the mounting cylinder 10 is covered at the facing away from the mask body 1 air outlet side with a protective grid 11.
  • cover plates 12, 13 of the tape guide part 2 form each with the spaced opposite outer surface of the mounting cylinder 10 an inner, lower - left and right - tape guide channel 14, 15.
  • Nach at the top closes to the cover plates 12, 13 respectively an upper - left and right - lying on the outer surface of the tape guide part band guide channel 16, 17 with formed at its end guide slot 18, 19 at.
  • the upper band guide channel 16, 17 is in the band guide surface in each case a slot opening 20, 20 'formed in this arranged first band friction web 21, 21'.
  • the transition between the upper, outer band guide channel 16 or 17 and the respectively angled abstrebenden lower, inner band guide channel 14 and 15 form two spaced parallel opposite rounded Bandumlenkkanten 23, 24 which define a clamping opening 25.
  • an adjustable clamping element 26 here in the form of a pivotable, two lateral clamping grooves 27 and a handle 28 having clamping lever arranged.
  • grip recesses 29 are formed on the outer surface, which allow easy handling of the respiratory half mask.
  • the band guide channels 14, 15 and 16, 17, the above-mentioned first and second band friction ribs 21, 21 'and 22, 22' are formed, around which the sidebands 4 can be placed so that the sidebands due to the frictional engagement between the Sideband and the pointed or edged frictional rib (s) are fixed to the tape guide part 2 and the mask can not be removed from the face even with dissolved clamping element 26 (non-drop-down position).
