Abstract
Abstract A dummy fire-arm (1) for training comprising a sighting device (2,3) and housing a laser tube (5). The fire-arm houses a high voltage portion (9) of the laser tube (5) triggering device (25, 30) as well as an optical focusing device (10, 11). This fire-arm (1) is carried by a lower portion (12) having a hand grip (13) housing the electronic control device of the laser as well as an electro-mechanical (25 to 31) shot departure triggering device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
A dummy hand fire-arm emitting a laser beam of short duration, comprising a pistol having a sighting device and housing a laser tube, the laser tube having a firing device having a high voltage portion and an optical focusing device for the laser beam, the pistol having a hand grip housing an electronic control means of the laser as well as an electro-mechanical triggering device for the beam, said triggering device comprising a trigger pulled by a finger of the user of the fire-arm, and means yieldably to resist pulling the trigger, said resisting means comprising a membrane which is displaceable and which acts against movement of the trigger to augment the pull of the trigger.
Claim 2
Dependent Claim
116 words
A dummy hand fire-arm emitting a laser beam of short duration, comprising a pistol having a sighting device and housing a laser tube, the laser tube having a firing device having a high voltage portion and an optical focusing device for the laser beam, the pistol having a hand grip housing an electronic control means of the laser as well as an electro-mechanical triggering device for the beam, said triggering device comprising a trigger pulled by a finger of the user of the fire-arm, and means yieldably to resist pulling the trigger, said resisting means comprising a membrane which is displaceable and which acts against movement of the trigger to augment the pull of the trigger.
Claim 3
Dependent Claim
125 words
A dummy hand fire-arm emitting a laser beam of short duration, comprising a pistol having a sighting device and housing a laser tube, the laser tube having a firing device having a high voltage portion and an optical focusing device for the laser beam, the pistol having a hand grip housing an electronic control means of the laser as well as an electro-mechanical triggering device for the beam, said triggering device comprising a trigger pulled by a finger of the user of the fire-arm, and means yieldably to resist pulling the trigger, said resisting means comprising a spring blade against which a portion of the trigger bears when pulled by the user of the fire-arm, said spring blade yieldably resisting rearward movement of the trigger.
Claim 4
Dependent Claim
125 words
A dummy hand fire-arm emitting a laser beam of short duration, comprising a pistol having a sighting device and housing a laser tube, the laser tube having a firing device having a high voltage portion and an optical focusing device for the laser beam, the pistol having a hand grip housing an electronic control means of the laser as well as an electro-mechanical triggering device for the beam, said triggering device comprising a trigger pulled by a finger of the user of the fire-arm, and means yieldably to resist pulling the trigger, said resisting means comprising a spring blade against which a portion of the trigger bears when pulled by the user of the fire-arm, said spring blade yieldably resisting rearward movement of the trigger.
Claim 5
Dependent Claim
46 words
A dummy fire-arm as claimed in claim 2, and means selectively to adjust the length of the spring blade which is subject to deformation upon rearward movement of the trigger thereby to modify the resistance of the spring blade to said rearward movement of the trigger.
