Rotatable and removable auxiliary eyewear system with snap alignment
The present invention discloses a unique and novel system for attaching an auxiliary lens assembly to a primary lens assembly in which the attachment includes two alternative positions, a lowered position and a raised position. In the lower position, the person wearing the eyewear system views through both the primary lenses and auxiliary lenses. In the raised position, the person wearing the eyewear system views only through the primary lenses. As a further option, the auxiliary lens assembly is easily removable from the primary lens assembly, allowing for separate storage of the auxiliary lens assembly when not needed. Slotted extensions on the primary lens frame receive retainers attached to auxiliary extensions on the auxiliary lens assembly. Each auxiliary extension has a rocker pivotally attached to a keyseat. An internal spring urges the rocker into snap alignment with the surfaces of the keyseat.
1. An eyewear system comprising:
a primary lens assembly having:
a primary frame for retaining a pair of primary lenses; and,
a pair of slotted extensions attached to the primary frame;
an auxiliary lens assembly including:
an auxiliary frame for retaining a pair of auxiliary lenses; and,
a pair auxiliary extensions attached to the auxiliary frame, each auxiliary extension having:
a bracket attached to the auxiliary frame;
a rocker pivotally attached to the bracket;
an arm extending from the rocker;
a retainer attached to the arm;
compressible bushing located in the retainer; and,
whereas the retainer is locatable within the slotted extension.
2. The eyewear system of claim 1 , the slotted extension further comprising:
a front extension portion;
a rear extension portion partially conjoined to the front extension; and
a slot formed between the non-joined portions of the front extension portion and the rear extension portion.
3. The eyewear system of claim 1 , further comprising:
a leg portion attached to each slotted extension.
4. The eyewear system of claim 1 , further comprising:
the bracket attached to the auxiliary lens frame on one end, and having a keyseat on its opposite end;
the keyseat having a top, and a substantially flat end face;
the rocker having an internal spring with a substantially flat end cap;
whereas the end cap engages the top of the keyseat when the auxiliary lens assembly is in the raised position; and,
whereas the end cap engages the end face when the auxiliary lens assembly is in the lowered position.
5. The eye wear system of claim 4 , further comprising:
the top of the keyseat is substantially perpendicular to the end face.
6. The eyewear system of claim 1 , further comprising:
the primary lenses are corrective lenses; and,
the auxiliary lenses are safety lenses.
7. An eye wear system comprising:
a primary lens assembly having:
a primary frame for retaining a pair of primary lenses;
a pair of slotted extensions attached to the primary frame; and,
an auxiliary lens assembly including:
an auxiliary frame for retaining a pair of auxiliary lenses; and,
a pair auxiliary extensions attached to the auxiliary frame, each auxiliary extension having:
a bracket attached to the auxiliary frame;
a rocker pivotally attached to the bracket;
an arm extending from the rocker;
a compressible retainer attached to the arm; and,
whereas the retainer is locatable within the slotted extension.
8. An eye wear system comprising:
a primary lens assembly having:
a primary frame for retaining a pair of primary lenses;
