Eye protection glass for goggles, protective masks and the like.

The present innovation relates to eye protection glasses, as they are used in protective goggles, protective masks and the like - to protect the eye To protect splashes, splinters and, if necessary, also from intense radiation.

It is known to use eye protection glasses for this purpose Use in protective goggles to protect the eyes against splinters, which are made of hardened single-layer glass or uncured multilayer glass. These eye protection glasses protect the eye from large ones

Splinters and are relatively smudge-proof. -On impact from smaller splinters there is a hole in it shown that glass fragments can detach from the side facing the eye, which under certain circumstances the Eye become dangerous.

Perner has already been suggested, eye protection glasses to use made of plastics that do not have this disadvantage. It is known, for example, at Work where small, fast-flying splinters are to be expected, protective glasses made of organic Use polymers. The plastic shields also have advantages over against flying splashes of liquid metals Glass panes insofar as the metal splashes on plastics do not stick while they are underneath Certain circumstances stick to glass panes, which can obstruct the view and destroy the glass pane «

Plastic panes, however, have panes of glass the disadvantage that they are not as smudge-proof, i.e. when wiping away the dust particles adhering to them the surface of the plastic disc is easily scratched.

The innovation is based on the task. " an eye protection glass for goggles, protective masks and the like to indicate the one hand on the to Observing object facing side has a great smudge resistance, but that on the The side facing the eye safely and reliably protects the eye from splinters.

The innovation is in particular that the side of the eye protection glass facing the eye is made of a plastic layer and the side facing away from the eye consists of a sheet of glass.

To achieve a neutral view it is advantageous if both layers are colorless, S ¹ Ur special processes, such as observing welding processes or other observations of highly radiant material, but it can be desirable for at least one layer to be colored β

In some applications, for example on protective masks, it is advantageous if both layers are flat are while using the eye protection glasses

According to the innovation in protective goggles it can be indicated when both layers are arched parallel to one another resulting in a lens with zero refractive power.

To correct eye defects, the plastic disc and / or the glass layer can be on both sides be curved differently, so that the eye protection glass has a certain refractive power or other, for correction receives properties that serve defects of the eyes "

If to achieve a certain filter effect

If a colored layer is to be used, it is advantageously curved plane-parallel or parallel educated.

In the drawing, embodiments of the subject of the innovation are shown, namely shows:

Ι »Example

Clear colorless or colored thermoplastics are made with an injection molding machine or plan domed panes without breaking strength or colorless thermoplastics to domed evenly on both sides Slices sprayed in the known v / ice. Laughter taking it out of the j? Orm is going to affect the eye remote side a colorless or colored, preferably uniformly thick pane of glass without additional Refractive power glued on. Transparent epoxy resins or silicone resins are advantageously used as the adhesive used.

2nd example

Clear colored or colorless thermosetting plastics are molded on a heating press to flat or curved panes without refractive effect or colorless thermosetting plastics to panes with optical Properties processed in a known manner, each dem

Removal from the form is done on the one facing away from the eye Side a colorless or colored, preferably evenly thick, glass pane glued. as Adhesives are advantageously used with clear epoxy resins or silicone resins.

3d example

Clear, colored or colorless monomers of polyesters mixed with appropriate hardeners, preferably Allyl compounds come in forms with elastic Walls, preferably made of silicone rubber, planar or curved panes in a known manner according to one corresponding to the respective resin-hardener system Temperature-time program to plan or polymerized domed panes. After losing weight on the side facing away from the eye, the porm becomes a colorless or colored pane of glass with a corresponding Glued radius of curvature. Clear epoxy resins or silicone resins are advantageously suitable as adhesives.

wise allyl compounds are polished to a Poured glass plate, the edges of which are closed with a frame about 1 cm high and the dimensions of which correspond to the available drying cabinets-r on two edges of the glass plate is about 5 ™ "wider and arbitrarily thicker Glass strips on which a second, somewhat smaller, also polished glass pane lies. The monomer is based on a corresponding temperature-time program polymerized to a solid plate. After removal from the mold, the plate is made with a diamond drill round slices or slices of any shape with a saw or a milling cutter.
