ABSTRACT:
Disclosed herein is an optical vise used to securely fasten glasses thereto for performing maintenance functions, suitably constructed so that the glasses retained therein will not be marred or otherwise damaged while being repaired. The structure disclosed herein includes a pedestal providing a support for horizontally extending trays that serve to carry tools and parts, a vertically adjustable support structure which carries at its vertical extremity remote from the base and vise proper. The vise is capable of rotation about a horizontal axis and defines a nesting area for securing foam or a similar soft resilient rubber material which serves to constrain the eye glasses disposed in a slit between two such pads. A back portion of the vise is provided with a similarly spongy material provided with slits along one face thereof so that the arcuate portion of the glasses which when in use hook around the ears of the wearer slide within these slits to provide further support. A rearwardly disposed support carries a light thereon to supplement the existing light in the area and the entire structure when assembled can translate laterally from back to forward for additional convenience in use.
