Firearm comprising a magazine detection group

Abstract

Firearm comprising a magazine, fitted with a carrier, and a detection group suitable to detect the presence of the magazine in the magazine housing and the presence of a predefined number of bullets inside it. The detection group comprises a firearm device, housed in the firearm comprising a plurality of primary sensors respectively comprising a switch and a magazine device housed in the carrier of the magazine, comprising at least a secondary sensor; wherein upon the change in height of the carrier the secondary sensor performs an action on the primary sensor proximal to it to perform the closing of the respective switch.

1 . Firearm comprising a magazine, fitted with a carrier, housed in a specially shaped magazine housing which extends along a magazine axis, wherein the firearm comprises a detection group suitable to detect the presence of the magazine in the magazine housing and the presence of a predefined number of bullets inside it comprising:
 i) a firearm device, housed in the firearm, preferably near the walls of the magazine housing, comprising a plurality of primary sensors arranged along the magazine axis;   ii) a magazine device, housed in the carrier of the magazine, comprising at least a secondary sensor;   wherein each primary sensor comprises a mechanical switch, and the secondary sensor comprises a ferromagnetic element;   in which at the change in height along the magazine axis of the carrier the secondary sensor by means of its magnetic field performs an action on the primary sensor proximal to it to perform the closing of the respective switch.   
     
     
         2 . Firearm according to  claim 1 , wherein the mechanical switch is a magnetic switch comprising an active portion, preferably of ferromagnetic material, suitable to close upon the action of the secondary sensor.
