| Abstract: |
A pair of goggles comprises a goggles frame with a pair of eyepiece holders, a nosepiece extending between inner end portions of the eyepiece holders, and a head strap extending between outer end portions of the eyepiece holders. Each eyepiece holder has an opening with an eyepiece unit fitted therein, the eyepiece unit having an overall length less than length of the eyepiece opening to permit relative movement therebetween to vary interocular spacing between the eyepieces to accommodate persons having eyes at different spaces. Guides are provided at outer end portions and intermediate portions of the eyepiece units and eyepiece holders to ensure axial movement of the eyepiece units with respect to the eyepiece holder with negligible rotation therebetween. A locator is provided to limit relative movement between the eyepiece holder and eyepiece unit. The locator can be fitted between adjacent outer end portions of the eyepiece holder and eyepiece unit to prevent movement of the eyepiece unit relative to the eyepiece opening.

We claim:
1. A pair of goggles comprising:
- (a) a goggles frame having a pair of eyepiece holders and a nosepiece extending between the eyepiece holders, each eyepiece holder defining respective eyepiece openings therein having opposite inner and outer end portions spaced apart along an interocular axis to define a length of the respective eyepiece opening, each eyepiece holder having opposite side portions spaced apart transversely of the interocular axis to define a width of the eyepiece opening, the eyepiece holders having inner end portions interconnected to the nosepiece and outer end portions connectable with a head strap,
- (b) a pair of eyepiece units fitted within the respective eyepiece openings of the eyepiece holder, each eyepiece unit having a lens with a respective ocular axis, the ocular axes of the lenses being spaced apart at an interocular spacing along the interocular axis, each eyepiece unit having opposite inner and outer end portions spaced apart along the interocular axis to define a length of the eyepiece unit which is smaller than the length of the eyepiece opening to permit relative movement between each eyepiece unit and the respective eyepiece holder along the interocular axis to permit adjustment of the interocular spacing, each eyepiece unit having opposite side portions spaced apart transversely of the interocular axis to define a width of the eyepiece unit which is approximately equal to the width of the respective eyepiece opening, and
- (c) position adjusters to permit adjustment of the position of each eyepiece unit within the respective eyepiece opening, each position adjuster comprising end and intermediate guides provided adjacent at least one end portion and one side portion of each respective eyepiece unit and associated eyepiece holder so as to be spaced apart at three locations for each eyepiece unit and associated eyepiece holder to provide stability for guiding axial movement of the eyepiece units along the interocular axis, and for preventing rotation of each eyepiece unit relative to the respective eyepiece holder.
