US 12,433,790 B2 · Tear-off lens capture

Abstract

A tear-off capture system includes an eye protector with a base lens. The eye protector has a retention mechanism mounted on one side, and a support mechanism that supports the eye protector on the head of a wearer. A two-tabbed stack of laminated tear-off lenses mounts to the eye protector via an adhesive. The stack mounts so that the first tab of the stack aligns with the first side of the eye protector and the second tab engages with the retention mechanism. Via the second tab and the retention mechanism, released tear-off layers are directed toward the second side of the eye protector away from the base lens. A capturer helps hold the initially released tear-off layer to the eye protector. An exposed tacky surface on each released tear-off helps hold the subsequently removed tear-off layers.

Dependent claims

A tear-off lens capture system for use with an eye protector having a base lens and a frame supporting the base lens, the system comprising:

a retainer configured to be mounted to an outward facing side of the eye protector so that the retainer extends away from the base lens, the retainer including an inner side facing towards the eye protector and an outer side;
and
a lens stack configured to be mounted to the outward facing side of the eye protector, the lens stack formed of at least one releasable lens layer, the lens stack comprising:
a central viewing area;
a first tab extending from a first edge of the central viewing area;
and
a second tab extending from a second edge opposite the first edge of the central viewing area, the second tab having an inner surface, a first portion of the inner surface facing the inner side of the retainer while a second portion of the inner surface faces the outer side of the retainer, the second tab folds over the outer side of the retainer when the lens stack is mounted to the eye protector and extends at least partly around the inner side of the retainer to retain the second tab on the eye protector when the first tab is released from the eye protector.

A tear-off lens capture system for use with an eye protector having a base lens and a frame supporting the base lens, the system comprising:

a retainer configured to be mounted to an outward facing side of the eye protector so that the retainer extends away from the base lens, the retainer including an inner side facing towards the eye protector and an outer side;
and
a lens stack configured to be mounted to the outward facing side of the eye protector, the lens stack formed of a plurality of releasable lens layers, the lens stack including a central viewing area, an intermediary adhesive layer between each of the releasable lens layers, a first tab extending from a first edge of the central viewing area, and a second tab extending from a second edge opposite the first edge of the central viewing area, the second tab having an inner surface, a first portion of the inner surface facing the inner side of the retainer while a second portion of the inner surface faces the outer side of the retainer, the second tab folds over the outer side of the retainer when the lens stack is mounted to the eye protector and extends at least partly around the inner side of the retainer whereby the second tab and one of the intermediary adhesive layers maintain a released lens layer on the eye protector.
