    OBJECT OF THE INVENTION
    The present invention relates to a cartridge detection system in a chamber for firearms that allows detecting the presence or not of a cartridge in the chamber in a reliable way while allowing this information to be supplied intuitively to the user.
    The object of the present invention is a cartridge detection system in a chamber for firearms comprising at least two armor through which it is possible to determine the variation of the electrical capacity between two possible states of the system, when there is no cartridge in the bedroom and when there is a cartridge in the bedroom.
    BACKGROUND OF THE INVENTION
    In virtually all existing weapons, the cartridge must be housed in the bedroom before it is possible to open fire. Thus, as far as safety is concerned, the existence of a cartridge in the bedroom is the most critical situation, since having a cartridge in the bedroom allows it to open fire immediately.
    The user of the weapon is always responsible for knowing the status of the weapon's bedroom. Uncertainty about the existence of a cartridge in the bedroom entails inherently insecurity and can lead to serious accidents.
    Some of the most widespread weapons incorporate mechanical indicators visible from the firing position that inform the situation of the bedroom. However, under conditions of lighting deficit it can be difficult to determine the presence of a cartridge in the bedroom by observing these mechanical indicators, so the uncertainty associated with the presence or not of a cartridge in the bedroom carries risks even greater than the uncertainty itself .
    Systems that allow controlling an electric weapon are known in the state of the art
    detecting the presence of a cartridge in the bedroom, where these systems present

    means for through a supply voltage, determine the impedance of the cartridge in two possible states of the system, when there is no cartridge in the chamber and when there is a cartridge in the chamber, using two reinforcements.
    Among the previous systems is the one described in the US5755056A patent relating to an electronic weapon and the procedure for controlling said weapon, where the armatures are positioned to electrically contact conductive portions of the ammunition cartridge, means to supply current to at least one of the reinforcements, means to measure the resistance between the reinforcements and means to compare the measured resistance with at least one reference.
    The system described in the previous patent comprises a comparator circuit to detect the presence of a cartridge, and in particular to detect ammunition that can be fired electrically. The circuit is formed by the contacts between the reinforcements and a cartridge. If the cartridge is present between the two armors, the current of one of the armors, which can be a firing pin, is transmitted, through the cartridge, to the second frame that can be the gun canon.
    However, the measurement of the impedance may be affected by the presence of the user, since the measurement may be falsified depending on whether the user comes into contact with metal parts of the weapon or not.
    The cartridge detection system for firearms of the present invention has a configuration that allows to solve all the above problems by providing a system that is independent of the situation where the user comes into contact with metal parts of the weapon.
    DESCRIPTION OF THE INVENTION
    The present invention relates to a cartridge detection system in a chamber for firearms that allows detecting the presence or not of a cartridge in the chamber in a reliable way while allowing this information to be supplied intuitively to the user.
    The cartridge detection system for firearms comprises at least
    a first armor, a second armor and a dielectric arranged between the first

    armor and the second armor, and a sensor circuit connected to a microprocessor, where the at least first armor is movable or varies the dielectric between a first position corresponding to the presence of cartridge in the chamber and a second position corresponding to the absence of cartridge in bedroom, or vice versa.
    The microprocessor, through the sensor circuit, detects the capacitive variation between the first reinforcement and the second reinforcement, between the first position corresponding to the presence of cartridge in the chamber and the second position corresponding to the absence of cartridge in the chamber, or vice versa , thus allowing to determine the presence or absence of the cartridge in the bedroom.
    Optionally, the cartridge detection system in the chamber for firearms also includes a motion sensor that activates the cartridge detection system when the weapon is subject to some type of movement.
    Optionally, the cartridge detection system in the chamber for firearms also includes a light indicator that indicates to the user the presence or absence of a cartridge in the chamber, where the indicator light is visible from the user's firing position without averting the gaze of the objective, and where the light intensity of the indicator light is sufficient to be seen by the user in high brightness conditions, but not excessive to dazzle the user.
    Optionally, one of the frames is arranged in the sensor circuit connected to the microprocessor.
    Preferably, in the first position corresponding to the presence of a cartridge in the chamber, the first frame is closer to the second frame than in the second position corresponding to the absence of a cartridge in the chamber, and therefore the capacity associated with the first position is greater than the capacity associated with the second position.
    Alternatively, in the first position corresponding to the presence of cartridge in
    bedroom, the first armor is further away from the second armor than in the
    second position corresponding to the non-presence of cartridge in bedroom, and therefore the
    capacity associated with the first position is less than the capacity associated with the second

    position.
    Also preferably, in the first position corresponding to the presence of the cartridge in the chamber, the area facing between the first frame and the second frame is larger than in the second position corresponding to the non-presence of the cartridge in the chamber, and therefore the capacity associated with the first position is greater than the capacity associated with the second position.
    Alternatively, in the first position corresponding to the presence of a cartridge in the bedroom, the area facing between the first reinforcement and the second reinforcement is smaller than in the second position corresponding to the absence of a cartridge in the chamber, and therefore the capacity associated with The first position is smaller than the capacity associated with the second position.
    Also preferably, in the first position corresponding to the presence of the cartridge in the chamber, the dielectric varies between the first reinforcement and the second reinforcement with respect to the second position corresponding to the non-presence of the cartridge in the chamber, and therefore the associated capacity The first position is different from the capacity associated with the second position.
    Thus, the cartridge detection system for firearms of the present invention allows to determine the capacity between the first reinforcement and the second reinforcement, between the first position corresponding to the presence of cartridge in the chamber and the second corresponding position to the non-presence of cartridge in bedroom, or vice versa.
    In addition, since there is no contact between the first reinforcement and the second reinforcement, the wear of the pieces is avoided, since they are subject to great stress or friction during the execution of a shot, they can suffer deformations, in addition to preventing the appearance of dirt by not There is a continuous contact between pieces.
    The sensor circuit allows converting the capacitive variation into a voltage variation.
    When the system intends to detect if there is a cartridge in the chamber, the microprocessor
    generates a signal with which the capacity of the sensor circuit is loaded which in turn depends

    of the state of the system and the variations of capacity of the sensor circuit can be measured.
    Optionally, the first armor and / or the second armor may / n be an element of the weapon, an element of the modified weapon or an element external to the weapon.
    Optionally, the first armor and / or the second armor can / n be movable or fixed.
    Optionally, the first armor and / or the second armor is located outside the bedroom.
    Thus, the cartridge detection system for firearms of the present invention has the following advantages over systems that have mechanical indicators visible from the firing position that inform the situation of the bedroom. These advantages are as follows:
    - The information can be displayed much more intuitively by means of the indicator light that indicates to the user the presence or not of a cartridge in the bedroom.
    - By having a motion sensor, the information is provided in a timely manner, preventing dangerous situations.
    - The indicator light is much more visible than the position of the mechanical indicator and the user does not need to look away to receive the information in shooting position.
    - Information can be received in low light environments.

    Next, the cartridge detection system for firearms of the present invention will be described in detail.
    In a first example of realization shown in Figures 1 to 3, the system comprises a first armor (1), which in this realization example corresponds to an extractor of the weapon that is in contact with the cartridge, a second armor (2), and a sensor circuit (3) connected to a microprocessor (4), where the first armor (1) or an extractor is movable between a first position corresponding to the presence of cartridge in the chamber and a second position corresponding to the no presence of cartridge in bedroom.
    The microprocessor (4), through the sensor circuit (3), detects the capacitive variation between the first reinforcement (1) or an extractor and the second reinforcement (2), between the first position corresponding to the presence of cartridge in the chamber and the second position corresponding to the non-presence of cartridge in the bedroom, thus allowing to determine the presence or absence of the cartridge in the bedroom.
    The second armature (2) is arranged in the sensor circuit (3) connected to the microprocessor (4).
    In the first position corresponding to the presence of a cartridge in the bedroom, the first reinforcement (1) or an extractor is closer to the second reinforcement (2) arranged in the sensor circuit (3) than in the second position corresponding to the no presence of cartridge in bedroom, and therefore the capacity associated with the first position is greater than the capacity associated with the second position.
    In this first example of realization, the first armor (1) or an extractor is an element of the weapon and the second armor (2) is an element external to the weapon.
    In this first example of realization, the first armor (1) or an extractor and the second armor (2) are located outside the bedroom.
    In a second example of realization shown in Figures 4, 5a and 5b, the system
    it comprises a first armor (101) or plunger arranged in a slide (110) of the

    weapon, a second armor (102), and a sensor circuit (103) connected to a microprocessor (104), where the first armor (101) or plunger is movable between a first position corresponding to the presence of cartridge in chamber and a second position corresponding to the non-presence of cartridge in bedroom.
    The microprocessor (104), through the sensor circuit (103), detects the capacitive variation between the first armor (101) or plunger and the second armor (102), between the first position corresponding to the presence of cartridge in the chamber and the second position corresponding to the non-presence of cartridge in the bedroom, thus allowing to determine the presence or absence of the cartridge in the bedroom.
    The first armor (101) or plunger is in contact with an extractor (111) of the weapon, where the first armor (101) or plunger is arranged in the slide (110) of the weapon. The first reinforcement (101) or plunger passes through a support piece (114) of an elastic element (113) that maintains tension on the first reinforcement (101) or plunger. Preferably, the first reinforcement (101) or plunger, the support piece (114) and the elastic element (113) are arranged in the longitudinal direction of the slide (110) of the weapon.
    When the cartridge is in the chamber, the one extractor (111) pushes the first reinforcement (101) or plunger out of a closure plate (105) through a hole (106) thereof.
    The second armature (102) is arranged in the sensor circuit (103) connected to the microprocessor (104).
    In the first position corresponding to the presence of a cartridge in the chamber, the first reinforcement (101) or plunger is closer to the second reinforcement (102) arranged in the sensor circuit (103) than in the second position corresponding to the non-presence of cartridge in bedroom, and therefore the capacity associated with the first position is greater than the capacity associated with the second position.
    In this second example of realization, the first armor (101) or embolus is an element of the modified weapon and the second armor (102) is an element external to the weapon.

    In this second example of realization, the first armor (101) or plunger and the second armor (102) are located outside the bedroom.
    In a third embodiment example shown in Figures 6, 7a and 7b, the system comprises a first armor (201) arranged in a slide (210) of the weapon, a second armor (202) arranged in the slide (210) of the weapon , and a sensor circuit (203) connected to a microprocessor (204), where the first armature (201) is movable between a first position corresponding to the presence of cartridge in the chamber and a second position corresponding to the absence of cartridge in the chamber .
    The microprocessor (204), through the sensor circuit (203), detects the capacitive variation between the first armor (201) and the second armor (202), between the first position corresponding to the presence of cartridge in the chamber and the second position corresponding to the non-presence of the cartridge in the bedroom, thus allowing to determine the presence or absence of the cartridge in the bedroom.
    The system also comprises a plunger (212) in contact with an extractor (211) of the weapon, where the plunger (212) is arranged in the slide (210) of the weapon, and where the first armor (201) is an element elastic that is in contact with the plunger (212) and maintains the tension on the plunger (212) when in contact with a support piece (214) that is arranged inside the first reinforcement (201) or element elastic, where the second reinforcement (202) is arranged inside the support piece (214).
    Preferably, the first reinforcement (201) or elastic element, the plunger (212), the support piece (214) and the second reinforcement (202) are arranged in the longitudinal direction of the slide (210) of the weapon.
    In the first position corresponding to the presence of a cartridge in the bedroom, the extractor (211) pushes the plunger (212) and consequently compresses the first reinforcement (201) or elastic element towards the support piece (214), so that the capacity between the number of turns of the first reinforcement (201) or elastic element facing the second reinforcement (202) arranged inside the support piece (214) is greater than in the second position corresponding to the no presence of cartridge in bedroom.
    In this third example of realization, the first armor (201) or elastic element is an element of the weapon itself and the second armor (202) is an element external to the weapon.
    5 In this third example of realization, the first armor (201) and the second armor (202) are located outside the bedroom.
    In a fourth realization example shown in Figures 8 and 9, the first reinforcement (101) or plunger of the second realization example becomes a first cylinder-shaped armor (301) 10, while the support piece (114 ) of the second embodiment example becomes a second reinforcement (302) in the form of a hollow cylinder, second reinforcement (302) which is the support piece of an elastic element (not shown) that maintains the tension on the first reinforcement (301) ) in the shape of a cylinder, so that two opposing armors (301, 302) are generated whose capacity depends on the area 15 facing between the two armors (301, 302).
