Headgear

Abstract

This invention relates to headgear for protecting the wearer against facial injury, especially eye injury, and in particular eye injury caused by flying particulate matter, such as may be ejected or expelled from a work-piece, the headgear comprising a first, transparent and substantially non-porous eye-protecting membrane and a fabric wall which substantially surrounds the first membrane. The wall is preferably flexible and porous and is attached to the first membrane at its periphery so as to support the first membrane in a vision-facilitating position adjacent the eyes of a wearer in use, wherein the first membrane provides eye protection against particulate projectiles while allowing the wearer to see through it, and the wall provides protection to the wearer against ingress of particulate projectiles from around the transparent first membrane.

Description

PRIORITY CLAIM[0001]This application claims priority to Australian application no. AU 2013900066, filed on Jan. 9, 2013, and to Australian application no AU 2013220865, filed on Aug. 26, 2013, both of which are incorporated herein by reference in their entirety.FIELD OF INVENTION[0002]This invention relates to headgear for protecting the wearer against facial injury, especially eye injury, and in particular eye injury caused by flying particulate matter, such as may be ejected or expelled from a work-piece.BACKGROUND TO THE INVENTION[0003]Many forms of eye protection exist Apart from spectacles and glasses such as industrial safety glasses and sunglasses, there are helmets such as welding helmets, biking helmets, skier helmets, goggles and fire-proof hoods. These have in common a hard protective lens and means for locating and holding in position the lens in effective viewing orientation opposite the eye of the wearer. Not all of these have eye protection as a priority, but more as ...

AI Technical Summary

Benefits of technology

The invention is about providing protective headgear for workers who work with abrasive materials that can cause eye injuries. The headgear is made up of two layers: a transparent, non-porous membrane and a flexible, porous membrane wall. The first membrane protects the worker's eyes from particulate matter, while the second membrane provides additional protection to the worker's eyes from ingress of particulate matter. The headgear is low-cost and suitable for mass production. It allows workers to see through it while still being protected from eye injuries.

Problems solved by technology

U.S. Pat. No. 6,880,176 to Timms et al. discloses headgear suitable for equestrian activities, but does not provide for eye protection, concentrating instead on preventing head injuries.

One weakness of safety glasses is that they can tend to lack protection means for particulate matter ricocheting toward the wearer's eyes from above, below and the sides.

Additional side mouldings or shields have been known to be provided with some models, but these add to the cost of these glasses, discouraging purchase, especially by budget-conscious operations.

Another drawback of the above types of safety glasses is that the added side protection means tend to reduce the all-round ability of the glasses to fit all users; one size does not easily fit all.
