| Abstract: |
The exchangeable lens eyeglasses of the present invention include a frame including a front preferably formed as a one-piece molded plastic part having a pair of spaced rims each having an upper end and a lower end with a bridge interconnecting the rims. The bridge defines an opening. The eyeglasses further include a pair of lenses with each lens supported by a corresponding rim. Each rim has an abutment surface disposed on one side of its lens and a support rib extending on the other side of its lens and cooperating with the abutment surface to seat that lens. The support rib is discontinuous between the lower end the upper end of its rim adjacent the bridge. The eyeglasses further include a retainer preferably formed as a one-piece molded plastic part which is releasably held by the front and has a component received in the opening. The retainer overlaps both lenses and cooperates with the abutment surface of the rims to capture the lenses. Release of the retainer permits removal of the lenses from the front.

What is claimed is:
1. Eyeglasses of the type having removal lenses comprising:
- a pair of lenses,
- a frame including a one-piece plastic front defining a pair of support rims having grooves formed therein with portions of the lenses positioned in the grooves and held thereby,
- bridge means on the front interconnecting the support rims at a central location therebetween,
- a pair of nose pads carried by said front and which diverge behind said lenses to partially overlap the lenses,
- said grooves releasably supporting the lenses on the front, and a one-piece retainer having a snap fit interconnection with the front at said bridge means and having portions sufficiently overlapping and engaging adjacent portions at the front of the lenses in the respective rims that said lenses cannot be removed from said front when said retainer is mounted on said front, said portions of said lenses being disposed inwardly of the peripheries of said lenses, said retainer having sufficient rigidity that it can be pushed from said front,
- said retainer being movable between a first retaining position in which the retainer engages the corners of the lenses so as to lock the lenses in the front and to prevent removal of the lenses from the front and a second position in which the retainer is removed from the front which permits removal of the lenses from the rims,
- an interlocking pin is formed on one of said bridge means and said retainer and a receiving opening for the pin is formed on the other of said bridge means and said retainer and said pin and said opening provide the snap fit to interlock the retainer to the front, said pin being bifurcated, having a pair of prongs spaced by a slot, the distal end of each prong being tapered, having a ramp surface for reception in said opening, said prongs being resiliently inwardly deflectable so that by pushing the retainer toward the bridge means with the pin aligned in the opening, the material of the bridge means defining the opening bears against the ramp surfaces causing the prongs to deflect together permitting full reception of the pin into the opening.
