Definitions

  • the invention relates to a protective helmet with a strapless breathing mask in a detachable connection according to the preamble of claim 1.
  • Such a protective helmet is known from US-A-3,990,757.
  • the detachable connection is formed by interlocking and lockable connecting elements arranged on both sides of the helmet and on the mask, namely as a connector receiving part on the helmet and as a connector part on the mask.
  • a movably resilient toothed member is arranged in the plug receiving part for connection to the plug part as a latching element, in which a toothed latch arranged in the plug part engages.
  • the detachable and / or fixed connection of the connector part in the connector receptacle takes place by means of the interlocking locking elements.
  • the disadvantage here is that, with such a connection, due to the possible double fits that result, not all tooth locks could interlock with one another, so that a secure connection is adversely affected thereby.
  • a detachable connection is also known from DE-A-26 40 701 on the side surfaces of the protective helmet and the respiratory mask by means of retaining means which can be plugged and locked into one another.
  • the holding means each consist of a cocking slide arranged on the protective helmet with an oval-funnel-shaped receiving part fixed thereon and a coupling pin arranged on the respirator mask.
  • the coupling pins which are equipped with unlockable locking balls, are inserted into the funnel-shaped receiving parts and locked there the respiratory mask is locked in a corresponding position on the protective helmet wall by means of a roller pressed along an inclined plane.
  • the invention is therefore based on the object of providing a protective helmet with a strapless respiratory mask in a detachable connection, the connection between the mask and protective helmet ensuring a permanent secure sealing of the mask on the face when worn and also compensating for all movements occurring between the mask and protective helmet is able to record.
  • the advantages achieved by the invention are, in particular, that when the protective helmet is put on, a quick and uncomplicated connection or connection of the mask to the protective helmet can take place, the individual adaptation and sealing of the mask on the face being automatically adjustable by the means provided in the connecting element, and can harmonize all movements of the detachably joined parts harmoniously.
  • the connecting element A is composed essentially of two parts, namely a connector part 3 articulated on the respiratory mask 2 on the lens frame 2a and a connector receiving part 4 arranged on the protective helmet 1 (cf. FIG. 2).
  • the connector receptacle part 4 consists of a housing 4a which is U-shaped in cross section and in which a slide 4b which is displaceable in the longitudinal direction against the force of a spring 10 is arranged and which can optionally be moved into predetermined positions and is positively fixed there (cf. Figures 3 to 6).
  • the key 11 is L-shaped and is supported at one end of the long leg piece 11a at the bearing point 12, while a pin 13 projecting therefrom is fixedly arranged to the short leg piece 11b.
  • the pin 13 interacts with an obliquely machined elongated hole 6b in the locking element 6.
  • a leaf spring 14 cooperating with the key is arranged in the slide 4b.
  • the leaf spring 14 clamped in the carriage 4b at one end 14a resiliently presses with the free end 14b against the short leg piece 11b of the button 11 and holds it in a rest position.
  • a pin 15 is arranged near the clamped end 14a, on which the plug part 3 engages for connection to the plug receiving part 4 by means of a tongue-like plug element 3d.
  • the plug-in element 3d has a through-hole 3d 'into which the spring-loaded pin 15 snaps into place, namely when the plug-in element 3d is inserted through an opening 4b' worked into the slide 4b.
  • connection of the plug part 3 to the plug receptacle part 4 made in this way can be released by depressing the spring-loaded button 11.
  • the pin 15 arranged on the leaf spring 14 then moves out of the through hole and thus releases the plug element of the plug part 3.
  • the plug part 3 consists in each case of a two-part bracket arm 3a and 3b, the parts of which can be plugged into one another and pulled out against the force of a spring 7 connecting the two parts, and of a on the lens frame 2a of the respiratory mask 2 by means of a pin 17 rotatably arranged base 3c, on which one bracket arm 3b is articulated to a pin 16 and from the plug element 3d movably arranged at the free end of the other bracket arm 3a by means of a pin 19.
  • the rotatable mobility of the plug-in element 3d around the pin 19 is limited by two stops incorporated in the plug-in element 3d ⁇ , which abut against a pin 20 arranged in the bracket arm 3a and surrounded by an elastic ring 9 (see FIG. 6).
  • a torsion spring 8 is arranged on the pin 16, which interacts with the bracket arm 3 and automatically swings it towards the mask body 2.
  • the side arms 3 are inevitably placed close to the mask body when the respirator is not connected to the protective helmet by the wearer.
  • the bracket arms 3 are thus protected on the one hand from damage and on the other hand can not cause any injuries even to the wearer.
  • the connector receptacle part 4 which is recessed laterally in a recess on the protective helmet 1 (not shown), is covered by a cap 18, which is provided with a grip part 18a, on which the wearer, for example, grips his hand fingers when the mask 2 is placed on the helmet 1, in order to be able to adapt the mask worn on the protective helmet close to the face.
  • the connecting element A The function of the connecting element A is described below:
  • the strapless respirator 2 is connected to the protective helmet 1 in such a way that the wearer, with the protective helmet on, introduces the tongue-like plug-in elements 3d of the respirator mask to be put into the connector receptacle part 4.
  • the leaf spring 14 arranged in the slide 4b is pressed down with the pin, and the pin snaps resiliently into the through hole 3d 'of the plug-in element 3d.
  • the breathing mask 2 is thus first connected to the protective helmet 1.
  • the breathing mask 2 coupled to the movable carriage 4b must be pushed backwards from the face for the tight adaptation of the respirator mask rim 2b to the head and face shape of the wearer, the carriage in the housing 4a of the connector receptacle part 4 in a corresponding position by means of the latching element 6 is locked automatically. This locking is non-positive.
  • the plug part 3 has a certain elasticity and rotatability. This is achieved on the one hand by the fact that the nested two-part bracket arms 3a and 3b of the plug part 3 are extendable against the force of the spring 7 and can be resiliently lengthened when the respirator mask 2 is adjusted, and on the other hand by the fact that the plug element 3d can be rotated to a limited extent and against the elastic stop 9 strikes damping, and that the base 3d of the plug part 3 on the viewing window frame 2a of the respiratory mask 2 can also be rotated to a limited extent. From this it is clear that the movements between the respiratory mask 2 and the protective helmet 1 are correspondingly balanced for the wearer and comfortable wearing of the two different components which are detachably joined to form a carrying unit is advantageously ensured.
  • the connector part 3 with the respiratory mask 2 is released from the connector receptacle part 4 of the protective helmet 1 by depressing the two spring-loaded keys 11.
  • the slide 4b in the housing 4a of the connector receptacle part 4 is released from its detent position and is released by the force of the spring 10 in pressed an end position forward, while on the other hand the arranged on the leaf spring 14 pin 15 moves out of the through hole 3d 'of the plug element 3d and releases it. From this it is clear that the key 11 triggers two functions simultaneously when depressed.
