Abstract
The invention is directed towards an apparatus for mounting and retaining a protective film that shields the surface of protective lens from vision-impairing accumulations of dust, mud, or other opaque materials. More particularly, the present invention is directed to a film retaining apparatus for use with a goggle with a renewable protective surface that offers increased film interchangeability. In one embodiment, the apparatus is comprised of spool for retaining the protective film having a spool end that is adapted to engage a film advancing mechanism in a first group of goggles, and an opposing spool end adapted to engage a film advancing mechanism in a second group of goggles. In another embodiment, the spool ends are removably coupled to a center cylindrical spool portion that retains the film to advantageously permit various engagement configurations to be used.
