  • Patent number: 6761467
    Abstract: A light beam modifier device for attachment to a light beam generator apparatus such as a flashlight or a weapon light. The light beam modifier includes an easily operable clamp for facilitating securement and removal of the light beam modifier device to and from the light generator. The device provides a positive locking closure between the flip-open door and the clamp, and further includes a spring hinge for permitting at least one and preferably two flip-open positions of the door out of the path of the light beam.

  • Patent number: 6508027
    Abstract: An accessory mount for a firearm, that may be quickly, easily and firmly secured to a firearm, and quickly and easily removed from the firearm. In combination with a firearm including a receiver, a barrel longitudinally extending from the receiver, and a lug secured to the firearm above the barrel, the accessory mount includes a longitudinal mount body positioned along the barrel with the mount body's rear end supported by the receiver, a lever pivotally secured to the mount body's front end about a first transverse axis, the lever pivotally secured to the lug about a second transverse axis spaced along the lever from the first transverse axis, and a longitudinally adjustable member carried by the mount body for urging the lever to pivot about the second transverse axis to rearwardly urge the mount's rear end against the receiver.
