Description

Protective helmet for sandblasting workers The invention relates to. a hard hat for sandstralil workers.

The invention consists in that a foldable frame is attached to a box that is firmly connected to the helmet and is at the level of the eyes, in which two glass panes are arranged one behind the other, of which the outwardly lying glass pane absorbs the impact of the grains and easily is exchangeable, while the inwardly lying glass pane, airtight ge , is sealed against the inside of the protective helmet.

The frame can be hinge-like around an am Zus, atzl, - asten; an, -, ebrac'bt.cii flat pin rotatable, and the hinge can be one-zn. have a flat slot, through which the pen home. Lifting the box is inserted through it.

There are already protective masks known in which the, windows order from two glass panes one behind the other, each of which faces outwards disc is easily exchangeable, while the inner one is gas-tight is inserted into the mask body. However, these known masks serve as protective devices for welders. It is also known in Gasschultzmasken, the window in one to arrange hinged box, which by means of a hinge in a mit-t the mask body firmly connected attachment box is attached.

In contrast, through. The invention of a protective hood for sandblasting workers can be created, in which the outwardly lying glass pane, which absorbs the impact of the sand grains and has to be renewed relatively often, because it is blinded by the: aufpra, - Ilenderi sand grains, can easily be exchanged, so that a comfortable handling of the protective device is achieved. Furthermore, if the air supply fails, the entire frame should be easily released and, d # a. it is also strongly subject to wear and tear from the fine grains of sand. can. The drawing shows an embodiment of the new protective helmet.

Fig. I is a view of the hard hat. Fig. 2 shows a section along the line AB in Fig. I, and Fig. 3 also shows: a section along the line AB in Fig. I, but with the attachment box folded down.

An attachment box b is attached to the helmet a, to which the hinged frame c, which holds the replaceable window pane! and the tightly fitting window pane, under the interposition of the seal 9, which closes gas-tight, is articulated by means of the hinge /.
