Abstract
Abstract A skeletal open-frame case providing protective covers for objective and ocular lenses of a binocular. The case has lenscovering caps or panels which are connected by a flexible strap, or which are made of magnetic material to be attracted to the binocular and to each other. The case collapses into a compact pocket-storable configuration when not in use.

A skeletal lens-protecting case for a binocular having a body supporting a pair of spaced-apart telescopes with objective and eyepiece lenses, the case comprising: an objective cover panel and a smaller eyepiece cover panel, the panels being elongated to fit over and cover both objective lenses and both eyepiece lenses respectively, the panels being substantially flat and each having a narrow peripheral wall extending therefrom to seat against the binocular body to prevent sideways slippage of the panel which would expose the lenses; and a flexible coupling means secured to and extending between the panels to prevent the panels from lifting away from the lenses; the case being collapsible into substantially flat form when removeD from the binocular by nesting the eyepiece cover panel within the objective cover panel, the case including securing means comprising a plurality of ribs on the wall of one panel and a matching plurality of grooves on the wall of the other panel to guide the panels into a nested position, the ribs having lips extending therefrom to grip the other panel in the nested position; panel including a tab extending therefrom for attachment to the flexible coupling means, the tabs being offset from centerlines of the panels so the tabs nest side by side when the panels are nested.
