## Abstract

An auxiliary spectacle frame has a substantially rigid elongate bridge member and dual monocular frames, the respective monocular frames being connected to the ends of the bridge member by spring members, whereby the monocular frames are omni-directionally movable relative to each other.

## Claims

### Claim 1

An auxiliary clip-on spectacle frame for detachable attachment to a conventional spectacle frame comprising: an elongate bridge member having opposite axial ends and which is substantially rigid at least in the plane of said auxiliary spectacle frame;
spring members joined at a first end to the opposite axial ends of said rigid bridge member, each of said spring members extending outwardly from the associated ends of said rigid bridge member;
a monocular frame rigidly attached to a second opposite end of each of said springs whereby each of said monocular frames is freely movable omni-directionally relative to the other and relative to said bridge member; and,
clip members carried by each said monocular frame for securement of said monocular frame to said conventional spectacle frame, said springs providing a resilient bias acting to maintain said clip members in secure engagement on said conventional spectacle frame.

### Claim 2 (depends on 1)

The auxiliary clip-on spectacle frame of claim 1, wherein said elongate bridge member is provided by a strip, which strip terminates at its opposite ends in a section of spring-like material to provide said spring members, said opposite ends being rotated to extend transverse to the plane of said bridge member.

### Claim 3 (depends on 2)

The auxiliary clip-on spectacle frame of claim 2, wherein said ends of said spring members are attached directly to said respective monocular frames.

### Claim 4 (depends on 1)

The auxiliary clip-on spectacle frame of claim 1, wherein each said spring member is a coil spring.

### Claim 5 (depends on 4)

The auxiliary clip-on spectacle frame of claim 4, wherein said elongate bridge member is provided by a rod, said springs are joined by an interference fit on opposite ends of said rod, and said monocular frames each include a projecting rod-like member that internally engages the free end of one of said springs in an interference fit.

### Claim 6 (depends on 4)

The auxiliary clip-on spectacle frame of claim 4, wherein said elongate bridge member is provided by first and second rods extending in substantially parallel relation, and the ends of said first rod are joined to said second rod at positions spaced inwardly from the respective ends of said first rod.
