Abstract: A periscope-type rear view mirror for automobiles which has a planar objective mirror positioned above an aperture formed through the roof of the driver's compartment of the automobile body for reflecting the light rays coming from behind the automobile forwardly and downwardly into the driver's compartment. A planar reflecting mirror is positioned substantially parallel to the objective mirror in the driver's compartment for reflecting the light rays reflected from said objective mirror forwardly and upwardly to a planar eye-piece mirror positioned close to said reflecting mirror and having a mirror surface crossing obliquely at an acute angle for reflecting the light rays reflected from said reflecting mirror into the driver's eye position. Said reflecting mirror is fixed to a stay, and said eye-piece mirror is pivotally secured to said stay which, in turn, is pivotably secured to the inner wall of the automobile at a position close to said aperture.

Abstract: A periscope-type rear view mirror apparatus for automobiles is disclosed. The apparatus includes a roof-top planar objective mirror positioned above an aperture formed in the roof of the driver's chamber of an automobile for reflecting forwardly and downwardly the light rays coming from the rear of the automobile into the driver's chamber, a first planar reflecting mirror positioned in the driver's chamber for reflecting forwardly and upwardly the light rays reflected by the objective mirror, and a second planar reflecting mirror positioned close to the first reflecting mirror for reflecting the light rays reflected by the first reflecting mirror to the eyes of the driver. The first reflecting mirror is supported by a pivotably hinged holder to allow the vertical angular adjustment of the holder, whereby the first reflecting mirror can be used as an ordinary rear view mirror of the type normally installed in the driver's chamber.
