Estimating the term…
A sliding binocular body has two optical assemblies which slide on an intermediate plate to adjust for intraocular distance and which slide closed. Two shells are joined to form one assembly. Front and back contour plates cover the assembly. A field and eye lens holder slides into the box through the back plate. An eye piece is attached to the lens holder. Inward horizontal surfaces have inward extending rails, which engage outward facing grooves on the intermediate plate. The two shells are secured together and joined to the intermediate plate before mirrors are slid and clamped into place. The objective lenses are placed in position, and the contour plates are sealed in place. The eye lens and field lens are inserted in the holders before the holders are inserted in the assemblies. The assemblies hold and clamp mirrors against fixed reference surfaces. Objective lens holders formed in the assemblies permit vertical or horizontal adjustment of an objective lens before its fixing. The intermediate plate has vertical projections on opposite ends which fit into recesses in the inward surfaces of the assemblies to limit outward travel and to hold the assemblies in closed position. The contour cover plates have projections to trap, or transparent extensions to cover, graphic skins or advertising paper boards or wraps.
A housing apparatus for an optical instrument, comprising a shell assembly having mirror mounts and an objective lens mount, and cover plates connected to the shell assembly, the cover plates having projections projecting into the shell assembly and engaging mirrors in the shell assembly, the shell assembly comprises first and second interconnected shells, the first shell having two mirror mounts for receiving angularly related mirrors, and the second shell having two mirror mounts for mounting two other angularly related mirrors, and the second shell having the objective lens mount for receiving an objective lens, the first shell further comprises a receiver for receiving an eyepiece holder, an eyepiece holder mounted on said receiver, the holder having a mount for receiving an ocular lens and a mount for holding a field lens, one of the cover plates comprises a rear contour plate connected to the first shell opposite the second shell, the rear contour plate having an opening for receiving the eyepiece holder, and having edges sealed to corresponding edges of the first shell for preventing ingress of light to the first shell, and the rear contour plate has projections which extend into the first shell for contacting backs of mirrors mounted in the first shell and supporting the mirrors against movement in said first shell.
