Abrégé

A locking device for a firearm having a firing chamber and an extractor, comprising: a cartridge-mimicking member configured to be inserted into the firing chamber and having a cartridge wall with an outer surface, a distal portion, and a proximal portion formed with an extraction rim, said extraction rim being configured to engage said extractor so as to allow pulling the cartridge-mimicking member at an extracting direction along a longitudinal axis extending between said proximal portion and said distal portion; a tightening mechanism comprising a resilient tube integrated in said cartridge wall, said tightening mechanism being configured for outwardly expanding said tube from a non-expanded state to at least one expanded state in which an outermost face of the tube protrudes with respect to said outer surface to an extent greater than at said non-expanded state; a locking mechanism switchable between an unlocked state in which said tube is at said non-expanded state so that pulling said extraction rim in the extracting direction allows extraction of said cartridge-mimicking member from the firing chamber, and a locked state in which pulling said extraction rim at the extracting direction relative to said tube entails expansion of said tube by said tightening mechanism to at least said one expanded state; and a processor in communication with the locking mechanism for switching the state of the locking mechanism at least from said locked state and said unlocked state.

Abrégé

Some aspects of the invention are related to a locking device for a firearm and a method of controlling such a locking device. The locking device may include a locking cartridge adapted to be inserted into a firing chamber of the firearm, the locking cartridge may include a cartridge-like housing and a locking mechanism located in the cartridge- like housing. In some embodiments, when the locking mechanism is in an unlocked state, the locking mechanism may be extractable from the firearm's firing chamber, by cocking the firearm and when the locking mechanism is in a locked state, cocking the firearm may fasten the locking mechanism in the firearm's firing chamber. The locking device may further include an actuator adapted to change the state of the locking mechanism between the locked state and the unlocked state and a controller, in active communication with the actuator, configured to operate the actuator according to a signal received from an input device. In some embodiments, the locking cartridge, the actuator and the controller are extricable from the firearm together as a single unit.
