  • Patent number: 4325609
    Abstract: A two-way mirror device for vehicles, and particularly for use as a side view mirror on heavy duty and medium duty commercial transport vehicles. The device includes a frame for holding mirrors, including a mounting means for mounting the frame on a vehicle. A semi-transparent plane mirror is mounted in the frame and positioned to permit viewing through the mirror and reverse reflected off of the mirror. A semi-transparent convex mirror is mounted in the frame and positioned to permit viewing through the mirror and an enlarged field of view reverse reflected off of the convex mirror. Finally, transparent backing means are attached to the frame for holding the plane mirror and the convex mirror such that forward viewing through the mirrors is also through the backing means. In a preferred embodiment, the vertical axis of the convex mirror is independently adjustable with respect to the plane mirror axis.
