<p>A viewing assembly includes a piece of transparent material (1) which is to be mounted within a door. A reflective surface (23) is mounted on the outer side of the transparent material (1), such that it can be seen by a person on the inside of the door, who is then able to see objects on the ground near the outside of the door. A bar extends horizontally across the inside of the transparent material to define a boundary between an image seen in the reflective and an image seen through the transparent material alone. A flap (50) is pivotably mounted to the inside of the door and includes a viewing slot and an angle protrusion (52) which is at generally the same horizontal level as the slot when the slot is in its rest position, but allows the user to see out through the slot when the flap is pivoted slightly. A plate is provided between the transparent material and the flap, with the plate defining a viewing aperture (42), the area of which is substantially less than the surface area of the transparent material. These features assist in one-way viewing through the transparent material. Also disclosed are features allowing the device to be mounted in a door such that it cannot be removed from the outside of the door.</p> |
