Abstract
Abstract The invention provides a viewing device, eye ''''glasses'''' or spectacles of such inexpensive construction that it lends itself to expendable use, as when fitted with orthogonally related polarized plastic lens elements, to enable 3-dimensional movie viewing. The lens elements are held in aligned and spaced relation by a compliant yet permanently deformable channel, which, in one form, is locally bent to define integral temples or ear pieces, which extend rearwardly of the general plane of orientation of the lens elements. A second and shorter length of what may be the same channel material is used as a bridge element, embracing corresponding other edges of the lens elements and also permanently and locally bent for comfortable support by the nose. The channel sidewalls are locally crimped at the bent localities to secure permanent assembly to the lens elements, and the channel section may be so devised that the indicated crimping is the inherent result of permanent bending.

Claim 1
Independent Claim
152 words
A spectacles construction, comprising an elongated channel of relatively stiff material selected for limited compliant deformability transverse to the elongation direction of said channel, said material being permanently deformably yieldable for bending deflections beyond the region of limited compliant deformability, optical-viewing lens means having an elongatededge portion received in a central part of the length of said channel and overlapped on both sides by the respective sidewalls of the channel, whereby non-overlapped portions of said channel extend longitudinally beyond both ends of the region of overlap of said edge portion, said channel being permanently bent in both non-overlapped portions adjacent the ends of said region of overlap and in the same general direction away from the general plane of orientation of said lens means, whereby the channel side walls in the bent non-overlapped portions are drawn together in permanently deformed enhanced retention of both ends of said edge of said lens means.

Claim 3
Dependent Claim
39 words
A construction according to claim 1, in which the non-overlapped portions project substantially equal distances beyond the bent portions and converge toward their ends, thus defining ear pieces which are spread against compliant resilient loading when worn for viewing.

Dependent Claim
71 words
A construction according to claim 4, in which said sheet material is characterized along said edge with a section thickness greater than that by which it is connected to the remainder of said lens means, said greater thickness being substantially wholly received in said channel, whereby the crimping of side walls inherent in the permanent bending deformation causes the side walls to envelop the greater-thickness region at least near said bends.
Claim 7
Dependent Claim
42 words
A construction according to claim 5, in which said greater-thickness edge is defined by an elongated surface groove parallel to said edge and formed in otherwise uniform-thickness lens material, the ends of the channel side walls substantially registering with the said groove.
Claim 8
Dependent Claim
26 words
A construction according to claim 5, in which the channel is one of two registering channels each formed on an opposite side of said sheet material.
Claim 9
Dependent Claim
63 words
A construction according to claim 1, in which said channel is of generally rounded U-shape, the outer ends of the side walls of the channel being converged toward each other to an extent exceeding the maximum separation of said sidewalls, whereby the inserted edge of said lens means is engaged in compliantly preloaded compression by said side walls along the region of overlap.
Claim 10
Dependent Claim
32 words
A construction according to claim 8, in which said channel comprises a U-shaped metal core, and a continuous coating of plastic material on both the inside and the outside of said core.
Claim 11
Dependent Claim
42 words
A construction according to claim 1, in which said lens means comprises two lens elements of plastic sheet material, each element having an edge received in said channel with the lens elements spaced to provide normal binocular viewing through the respective elements.
Claim 12
Dependent Claim
35 words
A construction according to claim 10, in which said channel is gently arched along the part which receives said channel, said arch being concave in the general direction in which said non-overlapped ends are bent.
