ABSTRACT:
An adjustable spectacle kit article is positioned in the interior of a self-contained breathing mask having a full face plate permitting viewing outside. The kit includes a bracket having an elongated slot for a lug attached to the mask interior. A portion of the lug includes a frame holder for spectacles having a frame for supporting at least one eyeglass lens and bridge. The frame connects with the lug for positionally adjusting within the mask. In one aspect, the lug is composed of polycarbonate polymeric material. A resilient elastomeric grommet inserted in the slot frictionally engages the lug. Another adjustable lug composed of a resilient neoprene polymeric material can replace the grommet. The lug is angular shaped, inserted into the slotted bracket, and frictionally provides for extensively adjusting the frame within the mask. The lug is sized for space utilization in a confined mask.
