Ammunition supply indicator device

Abstract

An ammunition supply indicator device installable in a firearm (11) the weapon (11) comprising a magazine (21) that includes several moveable means (22, 23) that slide in a longitudinal axial direction of the magazine (21); the device (12) comprising a specific number of receptor means (41) of the magnetic field generated by several actuator means (24) attached to the moveable means (22, 23), the level of the electrical signal depending on the relative distribution of the receptor means (31) in relation to the magazine (21), the type of material used to make the firearm (11), the magazine (21) and the position of the moveable means (22, 23).

Description

SCOPE OF THE INVENTION[0001]This invention refers, in general, to a system that indicates the supply of ammunition and, in particular, to a device for a portable firearm that is able to communicate the number of cartridges with bullets in a magazine and to a system that includes the magazine and a portable firearm.STATE OF THE ART[0002]With portable firearms it is difficult to determine the number of cartridges with bullets left in a magazine to be fired and, therefore; to be prepared to replace the magazine.[0003]Ammunition supply systems that include means for visually displaying the cartridges left in the magazine of a weapon are known in the prior art.[0004]Document U.S. Pat. No. 5,303,495 details an alarm device for when the ammunition in a magazine is finished, where the handle of a weapon includes, in the direction of forward movement of the floor plate of the magazine, a plurality of Hall-effect sensors, the number of which corresponds exactly to the maximum number of cartri...

AI Technical Summary

Benefits of technology

[0056]The indicator device 12 includes an on / off switching element 51 to minimize the electrical energy drawn by the device 12, see detail in FIG. 5.

[0057]The switching element 51 may be a pushbutton that activates the indicator device 12, via the power supply of the Hall-effect sensors 41. The push button 51 can be actuated by the shooter's finger when holding the weapon 11, without him having to make any additional movements.

[0064]The warning means or indicator will be located within the shooter's field of vision, such that he does not have to stop looking at the target to see the indicator. The light emitted by the LED is emitted outwards so that it can be seen by the shooter through a prism so that an LED of lower power may be used.

Problems solved by technology

With portable firearms it is difficult to determine the number of cartridges with bullets left in a magazine to be fired and, therefore; to be prepared to replace the magazine.
