摘要:
A releasably attachable face mask that forms a contiguous channel with an attached goggle to improve goggle ventilation. An elongated pocket or duct formed between two surfaces on the face mask mates with the goggle ventilation system to form the contiguous channel.The channel forms a venturi to draw air out from the goggle interior to the atmosphere through the contiguous channel.

A frameless goggle construction including an elongated lens structure having opposed ends formed of a generally planar, semi-rigid, transparent sheet of plastic deformed about its minor dimension to be configured as a simple curve with convex and concave sides. The sheet rigidity is such that the lens structure may flex to move the ends closer to or further from each other and the periphery of the concave side mounts a layer of soft resilient cushioning material of substantial thickness adapted for cushioned contact with and conformance to the face of a wearer of a goggle. An elongated strap is connected to the ends of the lens structure to secure the goggle to the head of the wearer and to provide a face conforming force to the lens. The lens structure is antifogging and formed of a non-rigid spacer sandwiched between inner and outer lenses with air flow passages formed in the spacer and inner lens.

Goggles, goggle attachment systems, and helmets are described. One such goggle attachment system includes an attachment post and a resilient goggle strap tab. The attachment post includes a post portion and a stop and the goggle strap tab includes an opening. The goggle strap tab is configured to be stretched and the opening pulled over the stop and onto to the post portion. The goggle strap tab is retained on the post portion by the stop. An example goggle includes a frame, a resilient strap attached to the frame, and a resilient goggle strap tab attached to the strap. The goggle strap tab having an opening disposed between a strap tab and a tab pull. The goggle strap tab is configured to stretch when pulled by the tab pull along a longitudinal axis and the opening being asymmetrical about an axis substantially perpendicular to the longitudinal axis when stretched.

The invention is directed to a reinforced nose bridge structure, eyeglasses employing the reinforced nose bridge structure, and methods of making reinforced nose bridge structures and eyeglasses. A reinforced nose bridge structure includes an elongated body and a wire extending along the body for most of its length. The ends of the wire project from the body to form a pair of spaced-apart nose pad supports. Respective nose pads are mounted at the ends of the wire forming the nose pad supports. The nose bridge may be attached directly to eyeglass lenses or to complete or partial frames for the lenses.

An anti-fog goggle is provided having a foam frame with a method of manufacturing the goggle. The goggle is composed of generally planar individual members, yet the goggle has a desired degree of self-supporting curvature. The anti-fog goggle has a semi-rigid support member for supporting the goggle's lens, the support member being stamped out of a planar sheet of foam. The foam support member has air channels depressed therein through which air enters and exits the interior of the goggle to prevent condensation from forming on the viewing surface of the lens' interior. The lens is stamped from a planar sheet of transparent plastic which is deformable into a simple curve. The lens is formed with a plurality of apertures therein which are aligned with air channels in the support member when the lends is secured thereto. The lens' apertures form ports through which air may flow into the air channels, the air channels directing the air downward across the inner surface of the lens. To make the goggle, the support member is curved about a form having the generally desired curvature and the lens adhered to the curved support member with an adhesive to deform the lens and support member into the form curvature which is substantially maintained when the lens and support member are removed from the form. The goggle may also include a cushioning foam member which is adhered to the inner surface of the semi-rigid foam support member to cushion contact with the wearer's face.
摘要:
A goggle is disclosed having a frame with upper and lower frame portions with the upper frame portion being substantially more rigid than the lower frame portion. A fastener secures the upper perimeter of a lens to the upper frame portion. The lower portion includes slots receiving tabs extending from opposing sides of a notch in the lens for receiving the wearer's nose. The fastener includes an elongate member insertable within a slot formed in the lens and rotatable to a crosswise position hindering removal of the elongate member from the slot.

This invention provides a stack of tear-off lenses for rapid and easy mounting over a main goggle lens. The invention overcomes the previously discussed disadvantages of excessive mounting time and effort. A method of manufacturing the stack is also provided. In addition, a goggle incorporating the stack of tear-off lenses, as well as a kit for adapting a goggle for tear-off lenses, including the tear-off lens stack and a retaining post member, are disclosed.

Lens assemblies and goggles are disclosed. One example lens assembly includes a lens having a plurality of vent openings and having a button opening elongated in shape. A button configured to fit and slide in the button opening includes a portion that extends through the lens and terminates in a button end. A shutter having a plurality of vent openings and a button attachment opening is attached to the button end at the button attachment opening. The vent openings of the shutter overlap the vent openings of the lens with the button in a first position and the vent openings of the lens covered by the shutter with the button in a second position.
