Abstract: A goggle has a replaceable plastic lens mounted in a flexible frame containing several air vents for passing external air through the goggle interior. The lens is formed of thermoplastic materials to provide spherical and cylindrical versions of the lens. The thermoplastic resins incorporate dyes which tint the lens to create a transmission curve with a broad flattened peak above a 50% transmission level and steep slopes to couple with the response characteristics of the rods of the human eye retina so as to improve contrast in very low light conditions such as night skiing under artificial light. Inlet and outlet air vents are covered by porous foam to reduce fogging in an outdoor environment.

Abstract: A motorcycle goggle includes a supply magazine and a take-up magazine mounted to opposite sides of a goggle frame and contain a transparent film which moves across the outer surface of a main lens to protect the main lens from mud or external matter. The main lens includes a plurality of projections attached to the lens to raise the transparent film off the main lens surface. The projections can be formed by transparent ink droplets which are printed by a silk screen process onto the outer surface of the main lens, and consist in one form of two types of ink forming each raised ink droplet.

Abstract: A goggle has a replaceable lens mounted in a flexible frame containing several large air vents facing forwardly to input external air into the goggle interior. The inlet air vents have converging and angled walls. A first porous foam of particular porosity covers the inlet air vents and is located in an upper air channel with a curved deflector wall to disperse the external air into the interior space. Exit vents located in the bottom of the frame are covered with a second porous foam of different characteristics than the first porous foam. The sides of the goggle frame include curved slots with curved retention bars around which a stretchable headband strap is secured to create uneven load forces on the sides of the goggle frame.

Abstract: A goggle has a replaceable plastic lens mounted in a flexible frame containing several air vents for passing external air through the goggle interior. The lens is formed of thermoplastic materials to provide spherical and cylindrical versions of the lens. The thermoplastic resins incorporate dyes which tint the lens to create transmission curves having peaks and valleys which approximate or enhance certain response characteristics of the retina of the human eye. Inlet air vents are covered by porous foam located in an upper air channel to disperse downwardly the external air into the interior space behind the lens. Outlet vents located in the bottom of the frame are covered with a porous foam to exit air from the interior space.

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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A motorcycle boot includes a lower vamp shell having a front tongue and rear tapering flaps which extend into an upper shell assembly formed by a hinged front door and a rear cuff. The door, of impact resistant plastic to protect the wearer's shin, interleaves with the cuff and is closed by overlying flexible straps. A closure system includes wire bales, longitudinally adjustable within holes spaced along the straps, and received with toothed latched receivers. The side legs of each wire bale snap-fits under locking flanges when the bale is closed over center. A connector hinge assembly includes a slotted plate, attached to the vamp shell, through which extends a freely movable pivot pin journalled in the upper shell to allow forward and rearward motion, rockable sideways motion, and lateral twisting of the shells. A replaceable sole insert, formed by a resilient pad molded to a carrier plate, is mechanically locked within a base recess on the bottom of the shell.

Abstract: A sports boot such as used for skiing has an upper shell interconnected in the ankle region to a lower vamp shell by a pair of side primary pivots. The lower edge of the upper shell has an integrally molded front receptacle which faces a front receptacle integrally molded into the upper edge of the lower vamp shell. The receptacles hold a replaceable resilient insert, the vertical extent of which determines the forward lean angle of the upper shell, and the resiliency of which controls the flex characteristics of the upper shell when pivoted relative to the lower shell. The ends of the receptacles form overlapping stop flanges which abut a replaceable bumper having a vertical extent which controls the maximum rear lean angle of the upper. Rear entry into the boot is provided by a rear door connected by a pair of side door pivots to the upper, and which overlaps a separate replaceable heel door with interior padding for holding down the wearer's heel.

Abstract: A ski glove or mitt capable of interlocking engagement with an extension on a strapless ski pole grip has a protective covering with a thumb stall and a finger stall for containing one or more fingers of the skier's hand. An interlock layer, stitched to the back of the protective covering, has a raised padding which surrounds a recess having a shape conforming to the shape of the grip extension for snugly seating the grip extension. A palmar layer of anti-slip fabric impregnated with a vinyl is stitched to the palm of the protective covering and has a stippled texture which mates with stipples on the grip body. Shock absorption is provided by a padded heel stitched to the heel of the protective covering where the bottom of the skier's hand engages a platform on the ski pole grip.

Abstract: A motorcycle boot has an upper wrap-around shell, closed by a buckle and strap, which overlaps a lower vamp shell having a plurality of forward and rear tapering fingers which extend into the upper shell to allow hinging movement of the upper shell. Flexible liners are inserted into the vamp to custom fit the vamp shell to a wearer's foot. An interconnecting hinge assembly includes a pivot pin, journalled in the upper shell, and slidably mounted within a slotted plate attached to the lower shell, to allow the upper shell to pivot forwardly and rearwardly and rock sideways. The base of the lower shell, with a steel plate embedded in the instep arch, is covered by a replaceable sole attached by adhesive which forms a rupturable seal. To waterproof the boot, a flexible cylindrical liner is sealed to the lower vamp and extends through the upper shell, with the liner top being folded down and externally attached to the upper shell.

Abstract: A strapless ski pole grip includes an elongated body having an axial bore for receiving the shaft of a ski pole. The elongated body includes a radially extending, palm engaging stop which terminates in a wide base to support the entire palm of the skier's hand, back to his wrist. The ends of the elongated body project outwardly and sideways to form side fingers which are located to lie against the back of the skier's hand. The pair of fingers are resilient and move sideways when the ski pole becomes captured to allow sliding withdrawal of the skier's hand.

Abstract: A goggle frame includes air vents spaced along its periphery and covered with a fibrous lining to vent the goggle interior while preventing entry of foreign matter. A detachable partial-face shield has snap-in posts which mate with apertures spaced along a bottom rim of the goggle frame. When the shield is attached to the rim, a shield nose section rests on a nose bridge of the frame, and shield side sections curve behind adjacent air vents in the frame to force frontal air therethrough. A main lens has locking projections received in a peripheral groove around the frame. One or more auxiliary lenses have edge regions received in the same peripheral groove, each auxiliary lens having an offset tab to allow a wearer to detach the auxiliary lens while the goggle is being worn.
