Abstract

The holder is for the banding of respieratory masks, and comprises a connecting boss with insertion passage. The boss (2), formed on the body of th mask (1), has an insertion passage of increasing cross-section. The insertion restriction for the lug at the end of the band has oblique or curved faces, so that when the lug bears against them some pivoting to either side is possible. The shape of the lug can be arranged to match that of th faces.

Description

The invention relates to the fastening of ribbons of full-mask diffusers, located on the mask body and consisting mainly of the ratio of the first nozzle with the transmission opening. Fastening of full-mask res ribbons is known, consisting mainly of rigid nozzles. The latter has a large and soy, a small recess that is connected to it, in which a locking pin of the double button connected to the mask is inserted. The side of the nozzle, turned away from the mask case, is provided with a fastening fungus, in a specially provided recess of which the earring is strengthened. In addition, the insertion of the protrusion, Hcd, 1c is approximately in the region of that part of the earring around which the ribbon is circled. When the ribbons are tightened, this part of the earring, and thus the ribbon in this place, is pressed against the protrusion, so that the ribbon is held due to the clamping. The detachment of the fastening of the straps is performed only by raising the fastening fungus on the nozzle, as a result of which the clamping is stopped. This attachment of the attachment to the mask body maintains its clamping effect even when the tape is not stretched. Circled by a ribbon and a part of the earring located between the bend and the mask body is clamped as a result of the integral design of the nozzle. Known mount, in the form of a molded to the body of the mask connecting nozzle with a stopper. This fastening excludes clamping with a relaxed ribbon. The nozzle on the mask body is made bridge-like: with a buckle detachable into two parts with a coupling element. One part of the buckle is a connecting part with a nozzle, the cross section of which approximates the lumen of the bridge on the mask body. This connecting part advances under the bridge in the direction of the tapes until the complete packing is provided as a bridge. The connecting part of the dream is a wife at the front end with an upwardly directed thickening and an opening open downwards into which the spike of the other part of the buckle is inserted. If the two parts of the buckle are connected to each other, it is possible to turn upwards for the tape-connected part of the buckle. This part of the buckle is made with holes in which the mask ribbon is threaded and set to a certain length. In this way, the additional tension of the straps is eliminated and their disconnection from the mask body can be made only by unhooking both parts of the buckle, i.e. just by pushing the spike out. the holes of the connecting part, ty. The fitting of the connecting part to the bridge also does not allow the fastener fastenings to be in a position deviating from the direction of insertion, as, for example, it is possible with the fastener fastened with a double button. The purpose of the invention is to create a simple attachment of cumbersome, cumbersome and expensive parts, as well as improving the replaceability of respirator tapes with a full mask, ensuring the mobility of the tapes in the outer and inner directions, as well as up and down. down while at the same time eliminating the negative effect of tension on the straps on the: edge of the mask body and its seal. This goal is achieved by the fact that the fastener mounted on the housing is made in the form of a connecting nozzle with a hole / gradually increasing in cross section, while the bearing surface of the connecting nozzle with a stop limiter formed by a narrowed edge of the through hole. coming out on this surface, facing the nozzle attached to the end of the ribbon, and the supporting surfaces of the connecting nozzle 2 and the nozzle 4 are made with a form, which allows the ribbon to rotate relative to the axis of the orifice. The supporting surface of the connecting nozzle 2 is made in the shape of a truncated cone, and the supporting surface of the nozzle 4 is made flat. The supporting surface of the connecting nozzle 2 is made spherically concave, and the supporting surface of the nozzle 4 is made spherically curved. The supporting surface of the connecting nozzle 2 is made flat and the supporting surface of the nozzle 4 is made in the shape of a truncated cone. To prevent accidental slipping of unstuck semes from the connecting nozzle in front of the nozzle 4, a stopper 9 is located at the end of the webbing, with the average cross section of it and the web or its width is less than the average cross section of the through hole
