Abstract
This invention concerns a supplementary safety device in the form of a false cartridge to be inserted into the chamber of a light firearm barrel, including a radially expandable portion controlled by a lock operated by a specific key for locking/unlocking it in the barrel in which it is housed, so it may be removed only voluntarily.
Claims9
Supplementary safety device that may be inserted into the chamber of light firearms such as shotguns, rifles, handguns and similar, characterised by:
- a first body (10) containing a lock (21) with a rotating part controlled by a specific key,
- a second body (11) linked to the first body and axially moveable, without rotating, between a position of unlocking when distant from and locking when close to the said first body;
- a screw pin (13) driven in rotation without moving axially in the first body, connected to and controlled by the said lock (21) for its rotation and linked directly or indirectly with the second body for the movement thereof between the said positions of unlocking and locking following the turning of the screw pin;
- and
- a flexible element deformable by compression (19, 20) located between the first and second bodies (10, 11) in order to expand radially and project peripherally from the said bodies when the second body (11) is in the lock position, thus creating the locking of the device in the chamber of the barrel in which it is housed.

- and
- a flexible element deformable by compression (19, 20) located between the first and second bodies (10, 11) in order to expand radially and project peripherally from the said associated bodies when the second body (11) is in the lock position, thus creating the locking of the device in the chamber of the barrel in which it is housed.
- a third body (12) associated and in line with the second body (11) and with an expandable winged wall (23) delimiting a conical cavity (24);
- and
- a conical plug (25) located and axially moveable in the conical cavity of the third body to radially expand the said winged wall (23) and additionally lock the device in the barrel if the said plug is subject to thrust in the direction of the chamber in an attempt to eject the device.
Safety device in accordance with the preceding claims in which the third body is independent from, integrated with or integral to the second body.
