SECURE ELECTRICAL PULSE APPLICATION DEVICE

Description

[0001] The present invention relates to an electrical pulse application device of the type generally used in personal protection and safety applications. In particular, it is a defensive device capable of stunning an assailant.

[0002] In the field of security, taser-type devices are known, which allow, for the safety of people, the application of electrical impulses to assailants or individuals deemed dangerous in order to neutralize them.

[0003] Unfortunately, this type of device usually applies uncontrolled electrical pulses that can lead to accidents on the wearer or the person neutralized.

[0004] Furthermore, this type of device is usually quickly detected by the people to be neutralized. This which limits its effectiveness.

[0005] Furthermore, a safety device in the form of a glove is already known from document CN205037814U. This glove has two electrical conductors on the palm side, one extending from the base of the palm to the tips of the thumb, middle, and little fingers, while the other connects the ring and index fingers, passing through the palm. A power controller connects these conductors to a rechargeable battery. Document CN102778173 B describes a glove with application contacts connected to a power source on all fingers, as well as secondary application contacts, all located on the palm side. The power source generates a voltage of 240V.

[0006] Document CN204924055U also describes a high-voltage electric shock glove, capable of withstanding 10,000 volts, featuring two types of conductive fabric electrodes on the palm, connected to a suitable power supply. These electrodes are covered by a first layer of insulating fabric and a second, enveloping insulating layer of polyester.

[0007] A primary objective of the invention is to provide a pulse application device that is easier to control and that significantly reduces accidents involving the wearer and the person to be neutralized.

[0008] A second objective of the invention is to provide a pulse application device that allows the intensity of the electrical pulse to be easily modulated according to the situation to be controlled.

[0009] To this end, the invention relates to an electrical pulse application device comprising at least one glove including a glove body ending in glove fingers, at least three of which are equipped with first application contacts connected to an electrical power source through a control unit, the glove further comprising second application contacts and the control unit comprising means for selecting to apply a differentiated electrical pulse between the first and second application contacts.

[0010] According to another aspect, the device includes at least one means of securing the application of electrical pulses.

[0011] Advantageously, the safety device is designed to control the application of electrical pulses under specific conditions and thus prevent accidents.

[0012] According to other aspects taken individually or combined according to all technically feasible combinations: said safety means comprises an alternation of terminals on preferably successive ends; and / or the alternation of terminals is carried out on at least three successive ends; and / or said safety means comprises a safety coating on the electrical pulse application contacts; and / or the safety coating comprises polyurea; and / or the safety coating has a thickness above said application contact of less than 1 mm and preferably greater than 0.5 mm; more preferably less than 0.85 mm and preferably greater than 0.65 mm; more preferably equal to approximately 0.75 mm; and / or at least one application contact comprises conductive microfibers;and / or the control unit includes means for applying to the first application contacts an electrical pulse of between 5 and 40 mAh, more particularly between 10 and 30 mAh depending on the load, and preferably between 220 and 260 V, more particularly around 240 V; and / or the control unit includes means for applying to the second application contacts a high-voltage electrical pulse exceeding 1000 volts, preferably exceeding 5000 volts, more particularly in the order of 20,000 volts. The device includes said power source, which is at least one battery fixed to a rear face of the glove; and / or the device includes a branch point for the application contacts on a palm opposite a ring finger, and / or a branch point for the application contacts on an outer edge of a palm.

[0013] The invention will be further detailed by describing non-limiting embodiments, based on the accompanying figures, in which: there figure 1 is a plan view of a front face of the device according to a preferred embodiment of the invention; the figure 2 is a view similar to that of the figure 1 illustrating the electrical assembly of said device; and the figure 3 is a three-dimensional view of a rear face of the device figures 1 and 2 .

[0014] The invention relates to a device for applying electrical pulses. This type of device is generally used in personal protection and security applications. In particular, it is a defensive device capable of stunning an assailant. This type of device can be used by law enforcement, security personnel, or even to control dangerous patients in psychiatric hospitals.

[0015] The device includes at least one glove 1, in particular a pair of gloves 1. Providing an electrical pulse application device in the form of a glove makes it more discreet because third parties do not know at first that it is a device of this type.

[0016] The glove 1 comprises a glove body 2 to receive the base of the hand, namely the back and the palm. This glove body 2 terminates in glove fingers 3, in particular at least three, preferably five glove fingers 3.

[0017] Adjustable fasteners with hook and loop fasteners such as Velcro™ strips are preferably provided on body 2, for example at the wrists.

[0018] The device includes a power source 4, which is at least one battery attached to the device. This battery or batteries 4 can be housed in a casing 4A on the back of the glove 1, corresponding to the back of a hand. The casing can be made of rigid plastic, which in particular serves to isolate the battery 4 from water and ambient humidity and to prevent tampering by unauthorized persons.

[0019] The aforementioned 4A housing, preferably prismatic or cylindrical, is mounted on the back of the glove 1, corresponding to the back of the hand, specifically at wrist level. Advantageously, this arrangement further enhances discretion, as the battery initially appears to be a watch. A 3.7V, 500mAh lithium battery can be used.

[0020] The glove 1 includes electrical pulse application contacts 5, 5A, these contacts 5, 5A being connected to said source 4, more particularly through a control unit 4B.

[0021] Thus, glove 1 has initial contact points 5 located at the fingertips 3, specifically on the front face of the glove, the palm side. These initial contact points 5 can also be located at the tips of the fingers 3, particularly on their front faces or along their length. Contact at the fingertips 3 is preferred because it helps to limit the size of the hazardous area.

[0022] Advantageously, glove 1 still has 5A application second contacts on its front side, at the palm level.

[0023] According to one variant, at least one, preferably all, of the 5,5A application contacts comprise a conductive fiber coating, advantageously made of conductive microfibers, enabling the easy propagation of electrical pulses. Furthermore, a conductive fiber coating is easily attached to a glove assembly, for example by sewing.

[0024] In one aspect, the device includes at least one, or in particular several, means of securing the application of electrical pulses. Advantageously, the safety means are designed to control the application of electrical pulses under specific conditions and thus prevent accidents.

[0025] According to one variant, one of said securing means includes a safety coating 6 on the first application contacts 5 and / or the second application contacts 5A of electrical pulse.

[0026] Thus, the device includes an insulating coating 6 on The application contacts 5 and / or 5A. Advantageously, an insulating coating 6 allows for a controlled distance to be created between an application contact 5 and / or 5A and the body to which the electrical pulse is applied. Thus, the invention provides distances that allow the device to be secured by partial insulation.

[0027] The invention makes it possible to significantly reduce incidents of electric shocks to the brain.

[0028] In addition, the insulating coating 6 makes it possible to conceal the application contacts 5 in that they are not visible from the outside, which further improves the discretion of the taser function.

[0029] In particular, depending on the conductivity of an application contact 5 and / or 5A, an insulating coating 6 with a thickness of less than 1 mm and preferably greater than 0.5 mm, placed over the application contact 5, provides a good balance between safety and sufficient impulse. When used with a first application contact 5 preferably made of conductive fibers or microfibers, a thickness of less than 0.85 mm and preferably greater than 0.65 mm, ideally around 0.75 mm, gives very good results.

[0030] In one variant, the insulating coating 6 contains polyurethane. Advantageously, polyurea allows for the achievement of desired thicknesses and serves as a reinforcing material due to its tear resistance. Furthermore, polyurea provides a leather-like exterior appearance, further enhancing the device's discreetness.

[0031] According to one variant, the device includes at least one, preferably two, branch points 7 at least for the first application contacts 5. The branch points 7 are connected, (in particular indirectly through a control unit as will appear below), to the terminals of the battery 4 and allow to have at output several connections at each terminal in particular a connection for each of the thermowell fingers 3.

[0032] More specifically, a branch point A+ of the positive terminal is provided on the palm opposite a ring finger. This area is generally not subject to much mechanical stress. In addition, a branch point B- of the negative terminal is provided on an outer edge of the palm. A reverse arrangement can be considered. The branch point B- of the negative terminal is then connected to the thumb, middle, and little fingers. The branch point A+ of the positive terminal is then connected to the index and ring fingers. The branch points can be covered with reinforcements 8. For example, a protective shell 8, which can be made of carbon fiber, is provided on the outer edge of the palm. A leather reinforcement 8a can be provided on a branch point, for example, on the branch point A+ of the positive terminal.

[0033] According to one variant, one of these safety features comprises alternating terminals on the ends, preferably successive ones. The alternating terminals allow a potential difference to be created by contact between several fingers. Advantageously, alternating terminals allow the user to use a finger without risk of electrocution, for example, in case of an itch.

[0034] In particular, this alternating terminal arrangement is implemented on at least three, preferably all three consecutive glove fingers. In other words, a first terminal, for example B-, is connected to a first finger, for example the thumb; then the other terminal, for example A+, is connected to the next finger, for example the index finger; then the first terminal is connected to the next finger, and so on. Advantageously, alternating terminals on more than two fingers allow the application of electrical pulses to be combined with a grip.

[0035] Alternating terminals can be positive and negative, or a terminal and a ground connection. "Plus" and "negative" terminals are preferred because they are safer, as a person in contact with the ground could be grounded and receive a shock from a single ungrounded contact.

[0036] According to one variant, the device includes a control unit 4B configured to apply an electrical pulse to application contacts 5 and / or 5A.

[0037] In particular, the control unit 4B includes means for applying, through suitable selection means 15, a differentiated electrical pulse between the first 5 and the second application contacts 5A.

[0038] Thus, this electrical pulse may have a different intensity and / or voltage at the first contacts 5 compared to that applied by the control unit 4B to the second electrical contacts 5A.

[0039] According to a preferred embodiment, the control unit 4B includes means for applying, at least at the first application contacts 5, an electrical pulse of between 5 and 40 mAh, more particularly between 10 and 30 mAh depending on the load, and preferably between 220 and 260 V, more particularly about 240 V. These values ​​correspond to a pulse that limits personal injury. A pulse of 240 V and 10 to 30 mAh, depending on the load, gives better results under normal operating conditions.

[0040] Advantageously, the control unit 4B includes means for applying at least to the second application contacts 5A a high voltage electrical pulse of more than 1,000 volts preferably greater than 5,000 volts, advantageously in the order of 20,000 volts.

[0041] Such a high-voltage electrical pulse allows transmission through clothing or even the fur of an animal to be neutralized.

[0042] The device preferably includes stop and start control means 16, as well as it may also be equipped with a charge rate indicator 9 of the battery or batteries 4 and / or an operating indicator 10, for example in the form of an LED indicator.

[0043] Advantageously, said housing 4A integrating the battery or batteries 4 also accommodates the control unit 4B and is preferably equipped on its upper part with the selection means 15 and the charge rate indicator 9 and / or the operating indicator 10 and / or the stop and start control means 16.

[0044] The entire device can weigh approximately 230 to 300 grams, preferably in the range of 250 to 260 grams.

[0045] Additional protective shells, possibly made of carbon fiber, are preferably provided on glove 1. For example, a protective shell 11 for the knuckle is provided. A protective shell for the phalanx 12 may also be provided, here with ventilation 13. Additional protectors 14, for example made of plastic, may be provided for the back of the fingertips.

[0046] Particularly to the invention, at least the glove body 2 is made from a cut-resistant carbon fiber-based fabric, more particularly poly(p-phenyleneterephthalamide), (PPD-T or REVLAR™).

[0047] In use, the glove is worn and switched on prior to using the electrical pulse application function. If so, the operating indicator 10 is active. The strength of the electrical pulse to be applied via the first 5 and / or second 5A contacts is selected using the selection means 15.

[0048] Thus, depending on the selected setting, a pulse applied for 0.5 seconds causes pain and muscle spasms and can neutralize an assailant. A pulse between 1 and 3 seconds can, in some cases, knock an assailant down and stun them for 1 to 2 minutes, causing muscle pain. A pulse of approximately 5 seconds will, in all cases, knock an assailant down and stun and disorient them for more than 3 minutes, causing muscle pain.

[0049] Battery 4 can be recharged in 2 hours for a battery life of 8 hours, for example.
