Abstract
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.
Claims42
A goggle comprising:
- a lens having right and left eye portions, the lens defining at least one slot;
- a frame selectively engaging a perimeter of the lens, the frame comprising an upper portion extending across an upper perimeter of the right and left eye portions and a lower portion extending across a lower perimeter of the right and left eye portions;
- a mounting structure disposed on one of the upper and lower portions, the combined mounting structure and the one of the upper and lower portions on which it is disposed being substantially more rigid than the other of the upper and lower portions;
- strap mounts pivotally mounted to the frame and a strap secured to the strap mounts;
- and
- a fastener disposed on the mounting structure and including a shaft rotatably secured to the frame, the shaft having a portion configured to be rotatable within the at least one slot and to selectively engage the at least one slot to retain the lens in engagement with the frame.
3 more elements
Eyewear comprising:
- at least one lens having an upper perimeter and a lower perimeter, the lens defining at least one slot proximate one of the upper and lower perimeters, the lens defines an opening extending from the perimeter of the lens to the slot, the slot being wider than the opening;
- a frame selectively engaging a perimeter of the lens, the frame comprising at least one of an upper portion extending across the upper perimeter and a lower portion extending across the lower perimeter;
- and
- a fastener having a lever and mounted to the at least one of the upper and lower portions, the fastener selectively engaging the at least one slot to retain the lens in engagement with the frame by moving the lever, the fastener further having an elongate member having a first end and a second end, the second end being wider than the first end.
1 more element
A method for assembling a goggle comprising:
- latching a lower perimeter of a lens with a lower frame portion of a frame;
- flexing the lower portion of the frame away from an upper frame portion of the frame;
- flexing the lower frame portion toward the upper frame portion while moving an upper perimeter of the lens into engagement with a rotatable fastener secured to the upper frame portion;
- and
- fastening the upper perimeter of the lens to the upper frame portion.
2 more elements
Eyewear comprising:
- a frame having at least one rotatable fastener;
- a strap mount pivotally mounted to the frame;
- a strap secured to the strap mount;
- and
- a lens having an outer perimeter, the lens defining at least one slot proximate the outer perimeter, the frame being removeably secured to the lens by selectively engaging each of the at least one fastener with a respective one of the at least one slot by rotating the fastener, the lens defines an opening extending from the perimeter of the lens to the slot, the slot being wider than the opening.
2 more elements
Eyewear comprising:
- a frame having at least one locking mechanism, the locking mechanism including a projection mounted on a shaft rotatably mounted on the frame, the projection having a first end and a second end, the second end being wider than the first end;
- and
- a lens having an outer perimeter, a portion of the outer perimeter of the lens defining at least one recess, the frame being locked to the lens by rotating the locking mechanism so that the projection is positioned in the recess to cause the frame to be secured to the lens, the frame being unlocked from the lens by rotating the locking mechanism so that the projection is positioned away from the frame to allow the lens to be removed from the frame.
