Apparatus For Converting A Pistol Into A Weapon Simulator
US Patent:
8602784, Dec 10, 2013
Filed:
Dec 4, 2009
Appl. No.:
13/132965
Inventors:
Vojtech Dvorak - Tulsa OK, US
International Classification:
F41A 33/00
US Classification:
434 18, 434 11
Abstract:
An apparatus for non-permanent conversion of a semiautomatic pistol into a compressed gas powered weapon simulator. The apparatus replaces the pistol's barrel, recoil spring and magazine with no modification of the pistol, which allows retaining the operational functions of the pistol's remaining components. Compressed gas, from the simulation magazine unit, is used in the compressed gas valve means, in the barrel unit, to operate the slide mechanism, to compress the simulation recoil spring, and to emit a laser pulse beam on a target when activated by the firing mechanism; and battery power, from the simulation magazine unit, is used to count the number of shots, lock the slide after a predetermined number of shots and transmit information from the weapon simulator to a remote data system. The compressed simulation recoil spring returns the slide mechanism back to its original position, unless locked open by the apparatus.
Trigger Analyzer
US Patent:
5761954, Jun 9, 1998
Filed:
Jan 21, 1997
Appl. No.:
8/785383
Inventors:
Vojtech Dvorak - Tulsa OK
International Classification:
G01L 514
US Classification:
73167
Abstract:
A device for measuring the entire profile of a firearm's trigger performance. This device may be either hand held or permanently mounted. The device may be connected to a sensor for sensing strike of the firing pin and connected to a computer for graphically and numerically displaying data relating to the firearm's performance. The device is capable of calculating key firearm performance parameters, including lock time and roughness of the trigger profile.
