Abstract
A face shield for a helmet comprises a body with an opening, an inner lens mounted in the body opening and a weather lens releasably mountable over the inner lens. The weather lens has a gasket around its perimeter which spaces the weather lens from the inner lens to form an insulating air gap between the inner lens and the weather lens. The weather lens is made of translucent material to selectively filter the light passing through the lens. The inner lens is recessed in the body so that the weather lens is generally flush with the outer surface of the body. Each side edge of the weather lens is provided with one of a hook and loop fastener and the inner lens has the complimentary fastener portion for mounting the weather lens to the inner lens.
Claims22
A face shield for a helmet comprising:
- a body having an opening;
- an inner lens mounted in said opening so as to have a convex outer surface and a concave inner surface;
- a weather lens overlapping said outer surface and mounted adjacent to said outer surface;
- means to space said weather lens from said outer surface so as to form an appreciable air gap between said weather lens and said outer surface;
- means removably attaching said weather lens to at least one of said inner lens and said body.
A face shield for a helmet comprising:
- a body having an opening;
- an inner lens fixedly mounted in said opening to form a recess;
- and
- a first fastener element on one of said body and said inner lens interengageable with a complementary fastener element of a weather lens of a type which is mountable in overlapping relation to said inner lens adjacent to said inner lens in said recess.
In combination,
- a weather lens and a face shield of a helmet, said weather lens comprising:
- a sheet of flexible plastic;
- a gasket extending from said sheet of plastic along a perimeter and on a first side of said sheet to space said weather lens from an inner lens forming part of said face shield, when said weather lens is mounted on said face shield;
- a first fastener portion, extending from said sheet on said first side, for mounting said sheet to said shield;
- said shield having a convex surface and a complementary fastener portion, comprising:
- a second fastener portion affixed to said convex surface of said face shield;
- an opposite surface for engaging said first fastener portion to mount said weather lens to said face shield in an overlapping relationship with said inner lens;
- whereby said weather lens may be quickly mounted and removed from said face shield, and said complementary fastener position.
