Abstract
The invention is an anti-ballistic, wide angle, one-way door viewer. It provides a safe and secure method of viewing through a door or other opaque structure, without placing the eye closely to the eyepiece in the viewer. The eyepiece has the following integral parts: (1) an optical lens barrel having large and smaller diameter lens in positions of reverse Galileo system, (2) a mounting barrel for through mounting to door or other structure and (3) an internal transparent anti-ballistic glass partition, supported by a metallic support sleeve spacer. The smaller of the two lenses is secured from the receiving side by a threaded cap that is fashioned to secure two mirrored prisms. The prisms use the reflecting surfaces to provide an 180° viewing panorama and eliminate the use of any reverse optical device from being used to gain a view in the opposite direction.
Description
ANTI-BALLISTIC WIDE ANGLE ONE-WAY DOOR VIEWER
I. TECHNICAL FIELD
This invention relates to viewing devices, more particularly to door viewers, also referred to as "peep-holes" or "spies" and even more particularly to anti-ballistic (bullet proof) door viewers of the type having an elongated lens holding barrel for installation with a door of a dwelling or more particularly to the door of a motor vehicle such as an aircraft cockpit door, marine vessel, train or similar piloted transit system.
π. BACKGROUND ART
Viewing devices of the type for installation within the outer door of a dwelling to enable the resident thereof to recognize and identify the caller have been in widespread use for many years. The original designs of such viewers being described in U.S. patent numbers to Shackley 878,24; Baner 1,737,291; and Hardt 2,169,874. These devices have been refined to the more popular "barrel" type viewer comprising a main cylindrical housing (barrel) for installation within the door. The front of the barrel being configured with a circular flange for retention of a wide angle lens designed to optimize the field of view. A typical representation being described in U.S. patent no. 2,638,810 to Berleme. Although present designs of "barrel" type viewers have generally accomplished their intended purpose, they are not satisfactory for all applications or conditions of service. Most significantly, the viewers are not anti-ballistic and are easily penetrable by a ballistic projectile such as a bullet. As a consequence, the occupants and items on the viewing side of the viewer are at risk of serious injury, death, or damage if a bullet were shot through the viewers that are currently available.
Another disadvantage of current viewers is the Galileo type lens configuration is easily reversible using a readily available reverse optic device. This allows complete wide angle viewing from the intruder side of the door into the dwelling, cockpit or similar private area. This viewing opportunity provides the would be intruder with the opportunity to attempt access at the most vulnerable moment and/or determine when the occupant will be intending to open the door and the ability to time his forced entry accordingly.
πi. DISCLOSURE OF INVENTION
It is a principal object of the present invention to provide a new and improved design of a door viewer to overcome the disadvantages of the currently available viewers above. This invention provides a new and improved barrel type door viewer that has a transparent, anti-ballistic (bullet proof) internal partition providing anti-ballistic performance not existing in current wide-angle viewers. This invention is a barrel-type viewer of improved design that is suitably constructed to be certified under Federal Aviation Administration regulations for use in the cockpit door of commercial aircraft. The viewer is comprised of an optical lens barrel having large and smaller diameter lens in positions of reverse Galileo system, a mounting barrel for through mounting to door or other surface, an internal transparent anti-ballistic glass partition, supported by a metallic support sleeve spacer. The smaller of the two lenses is secured from the receiving side by a threaded cap that is fashioned to secure two mirrored prisms that use the reflecting surfaces to provide a 180° viewing panorama and eliminate the use of any reverse optical device from being used to gain a view in the opposite direction. IV. BRIEF DESCRIPTION OF DRAWING
In accordance with these and other objectives, the door viewer of the present invention comprises a prism/mirror mount cap (A), prism mirrors (B), prism support sleeve (C), non-frangible trim ring (D) located in front of the receiving lens to provide non-reversible optic performance, and provide 180° wide-angle viewing. Further objectives are accomplished by installing the transparent anti-ballistic partition (E) which is supported by metallic sleeve (F) and retained by joining threaded metallic barrel (H) into metallic barrel (I). The joining of (H) to (I) secures lenses (J) and (K) without bonding so they can be easily replaced if damaged. The viewer is secured with a door or similar opaque structure by means of tightening mounting ring (L) against the occupant side surface of the door/structure.
Further features and benefits will become more readily apparent from the attached cross sectional view of the viewer assembly with components clearly identifiable using corresponding letters A through L.
V. BEST MODE FOR CARRYING OUT THE INVENTION
The best method for carrying out this invention is in the attached design drawings. Prototype units have been assembled in accordance with this drawing, and tested for optical performance as well as ballistic performance in accordance with N.I . level 3a ballistic penetration requirements.
VI. INDUSTRIAL APPLICABILITY
This invention has many industrial applications including aviation for both fixed and rotor winged aircraft, aerospace, various forms of mass transit including trains, buses, ships etc. There are also many applications in other industrial sectors including any building and/or structure in which the resident(s) desire visual verification of visitor(s) and also desire protection from ballistic projectiles, and more specifically from hand held firearms during the verification process. This invention is intended to minimize if not eliminate serious injury or death for the resident.
Claims
(1 ) A viewer; for incorporation in a door such as an aircraft cockpit door, or other opaque structure that will provide wide angle, one-way secure viewing and anti-ballistic protection for the viewee and/or flight instrumentation, or any other items that could be damaged by a ballistic impact.
(2) A viewer: as recited in Claim 1 wherein said construction can be certified for installation in an aircraft cockpit door or other opaque structure, fully compliant with Federal Aviation Administration requirements.
(3) A viewer; as recited in Claim 2 wherein said viewer provides 180° wide angle, one way viewing by means of prism shaped mirrors secured in a metallic cap.
(4) A viewer; as recited in Claim 3 wherein said viewer provides non- reversible viewing by means of prism-shaped mirrors retained behind a metallic cap.
(5) A viewer; as recited in Claim 4 wherein said viewer is constructed using a transparent anti-ballistic (bullet proof) partition supported by a metallic support sleeve.
(6) A viewer; as recited in Claim 5 wherein said viewer provides anti-ballistic (bullet proof) protection and has readily perceptible viewability without closely approaching the eyepiece.
(7) A viewer; as recited in Claim 6 wherein said viewer is constructed using non-flammable materials, suitable for use in commercial aircraft, and marine vessels, trains and other mass transit systems, in which flammability, toxicity, and heat release are of concern.
