  • Patent number: 10060181
    Abstract: An innovative ballistic door is disclosed that is destined for use in schools, offices and building structures. The innovative door comprises a hybrid ballistic core, comprising at least two sections, wherein one section is a heavy impact resistant material rated to NIJ level III strength to resist rounds fired from high-powered rifles, as well as resisting breaches from explosive devices such as pipe bombs and the like. AR500 steel plate having a thickness of ΒΌ inch meets this requirement. The remaining sections of the innovative ballistic hybrid core comprise at least one lighter-weight ballistic sheet material, such as E Glass fiber composite sheet, which at least comply with the NIJ level IIIA standard. This E Glass material is ideally suited to resist the impact of a pipe bomb explosion. The novel ballistic core construction allows a compromise between protective and practical weight requirements.

  • Patent number: 8950114
    Abstract: A blast and projectile resistant gun port is provided with both a roller-slide mechanism and a lever-actuated, spring-loaded, cam mechanism which a shooter operates to open or close a gun-port door over a gun-port opening in a gun-port frame, as well as to translate the gun-port door out of the way of the gun-port opening. The shooter is able to effect these actions by nudging the lever on the cam mechanism with or without placing one or more hands on the lever and is thus able to keep both hands on weaponry. The gun-port door keys into its closed position, and an elastic weather seal is squeezed firmly between the gun-port door and the gun port frame when the gun-port door is closed. The squeezing of the weather seal is effected by springs in the cam mechanism. The gun-port door and the components and subassemblies are easily and rapidly replaceable.

  • Patent number: 5518175
    Abstract: The present invention is directed to a mail slot mounting assembly which can be easily installed onto the cross-bars of an existing door without the need for welding or extensive cutting operations to the door frame. The mounting assembly has upper and lower face plates each having an inner surface to be mated and a first pair of wall members running longitudinally along and substantially perpendicular to each of said inner surfaces. The inner surfaces of the upper and lower face plates are configured so that, upon mating the face plates, the first pair of wall members align to form outer channel regions extending longitudinally along and perpendicular to the face plates, the outer channel members being adapted to receive mounting members located in a door. The mated face plates are then configured to receive a mail slot apparatus.

  • Patent number: 5359795
    Abstract: An insulated door for use in a refrigerator having an ice and water through the door dispenser is made by attaching a liner for housing the dispenser on the rear face of the door in line with a front opening. The liner is secured to the door as are the hinge bearings and a tube extends between the liner and the lower hinge bearing for conducting electrical wires and a water tube. The only opening in the liner is at a point to receive ice cubes from the dispenser in the refrigerator and this opening is covered prior to foaming. The door is placed in a foaming fixture which completely enclosed and supports the door and the liner and foam is injected so that the foam, when expanded and hardened, completely covers the rear face of the door. After the door is removed from the foaming fixture, the thin layer of foam at the inlet opening is cut away and the door is completed by adding the liner and the gaskets and other hardware as well as the dispensing unit itself.

  • Patent number: 5287654
    Abstract: A modular pet access door unit for insertion into a hole cut into a door or wall has exterior frames and spacer frames, fastened together by fasteners extending horizontally through brackets in the spacer frames. The spacer frames have tongue and groove surfaces for nesting with each other. Both exterior frames may carry a pet access door. A security cover mounts on posts with annular grooves, and may be moved horizontally into position to cover the pet opening, where sliders in the security cover with keyhold-shaped holes engage the post annular grooves. The pet door is captured in the frame between the frame and a door or flap holder that is secured to the frame by removably fasteners. An automatically adjustable sill is movable by magnetic attraction to the flap bottom, where its position is secured by fasteners.
