Definitions

the invention relates to respiratory masks with front lenses that can be attached as light filters in front of the viewing windows provided in the mask body.
the mask body made of a flexible material of respiratory masks viewing windows are inserted at eye level of the user.
front lenses made of a material that filters the rays of light, if necessary, in front of the lenses A holding frame is provided on the mask body in the circumferential area of the viewing panes to fasten the front screens, while the front screens are embedded in a rubber sleeve on the peripheral edge.
the attachment of the front lenses, in which the rubber sleeve is put over the holding frame, is tedious and time-consuming and involves considerable difficulties when wearing protective gloves.
the invention is therefore based on the object of designing a respirator mask and the attachment lenses for light filtering which can be temporarily attached to it in such a way that a fast attachment of the attachment lenses and beyond is possible independently of outside help in use, that is to say with a mask attached in addition, the space occupied by the front lenses and the fastening system and protruding beyond the mask body is small.
the object is achieved with a breathing mask with front lenses designed according to the features of claim 1.
the basic idea of the invention is that the flexible elastic lens, which is identical both in the outer contours and in the curvature with the lens, is fixed directly on the lens to locking means integrated in the opposite side edges thereof, for fast, correct positioning Arrangement of the front lens on the lens, a guide means is molded.
the front lens When attaching the front lens, it is first aligned on the lens using the guide means, then held in the first locking means and then - with slight elastic bending - finally fixed in the opposite second locking means, tightly on the lens.
Both the viewing window and the front lens are simple and therefore inexpensive to manufacture.
the attachment of the front lenses can be done without tools or outside help when the respirator mask is on. in no time.
the front lens is securely fixed, but removing it is not difficult.
Another advantage is the small space requirement, since the overall height is only increased by the thickness of the front lens.
the guide means is formed by a stop web which is formed in a corner region of the viewing window and defines a guide pocket on the edge thereof.
locking hooks are formed on two opposite edges of the lens, each consisting of a vertical web and a horizontal holding web. In the area in which the attachment disc lies under the latching hook in the assembled state, depressions are formed in each case in the attachment disk such that the upper edge of the latching hook is flush with the surface of the attachment disk.
the front lens - viewed towards the viewing window - is concavely curved, so that the slight elastic bending of the front lens required for assembly or disassembly is possible in a simple manner.
a finger recess is formed in the edge area of the cover plate. This makes handling the front lens easier during assembly and disassembly.
FIG. 1 is a top view in perspective view of a viewing window and a front lens partially held thereon shortly before
FIG. 2 is a front view of the lens and front lens system of Fig. 1;
FIG. 3 shows a plan view of the viewing window and front lens system with the front lens completely attached
FIG. 4 shows a front view of the system according to FIG. 3.
the lens 1 is curved and has a circumferential groove 2, via which it is connected to the mask body of a respirator (not shown).
a guide pocket 4 is formed for the correct arrangement of a front pane 5 on the viewing pane 1.
the guide pocket 4 is formed by a stop web 6 which rises vertically from the surface of the lens.
First and second locking hooks 7 and 8 are formed on the opposite side edges of the lens 1, each of which consists of an elongated web 7a or 8a extending perpendicularly from the windshield surface and a holding bar 7b or 8b pointing horizontally to the lens center. From Fig. 4 it can be seen that the stop web 6 merges into the web 7a of the first locking hook 7.
the shape of the front lens 4 corresponds essentially to that of the viewing window 1 in terms of the edge shape and the curvature of the lens surface.
the front lens 5 In the edge region, in which the front lens 5 lies under the first locking hook 7 and the second locking hook 8 in the assembled state, the front lens 5 a first and a second sales recess 9, 10 (material weakening) molded in, the length and width of which is slightly greater than that of the horizontal webs 7b and 8b of the latching hook in question.
a finger recess 11 is formed on the lens 1 in front of the second depression 10.
the front lens 5 is slightly deformable in one direction due to the curved design, but is nevertheless slightly elastically deformable.
Attaching the front lens 5 to the lens 1 is carried out as follows:
the front lens 5 is inserted with its angled (pointed) side into the guide pocket 4 up to the stop web 6 and thereby automatically assumes its correct position with respect to the lens 1.
the first recess 9 slides in the front lens 5 under the first locking hook 7, so that the front lens 5 is already locked on one side of the lens 1.
the front lens 5 is curved somewhat more so that the second recess in the front lens 5 also comes under the second latching hook 8, the front lens being located 5 stretches again due to its inherent elasticity and the second recess 10 slides under the second latching hook 8.
the front lens 5 is thus securely locked perpendicular to the surface of the lens, but is fixed in all lateral horizontal directions due to the curved shape of the holding web 8a and the stop web 6.
the front lens 5 can easily be removed again from the viewing window 1 by the front lens 5 being elastically curved more strongly by lateral pressure on the finger recess 11, so that it can slide out of the second latching hook 8 and then be removed upwards. Due to the design of the lens with guide pocket and stop bar as well as the two latching hooks located opposite each other on the side edges of the lens, it is possible to attach the lenses easily, quickly and safely with the respirator mask on without outside help.
the front lens lies essentially on the viewing window, so that the height of the structure in front of the viewing window is determined solely by the thickness of the front window and is therefore extremely low.
