The present invention relates to a device for applying an electrical pulse of the type generally used in applications for personal protection and safety. It in particular relates to a defensive device for stunning an assailant.
In the security field, devices are known of the taser type, making it possible, for personal safety, to apply electrical pulses to attackers or individuals deemed dangerous in order to neutralize them.
Unfortunately, this type of device generally applies uncontrolled electrical pulses that may lead to accidents on the wearer or the neutralized person.
Furthermore, this type of device is generally detected quickly by the persons to be neutralized, which limits its effectiveness.
Moreover, a safety device is already known from document CN205037814U in the form of a glove including, on the palm side of the hand, two electrical conductors, one of which extends from the base of the palm to the end of the thumb, the middle finger and the pinky finger, while the other conductor connects the ring finger to the index finger by way of the palm. A power controller connects these conductors to a rechargeable battery.
Document CN204924055U discloses a high-voltage electric shock glove on the order of 10,000 Volts including, at the palm, two types of electrodes made from conductive fabric connected to an appropriate electrical power supply. These electrodes are covered with a first layer in the form of an insulating fabric and a second surrounding insulating layer made from polyester.
A first aim of the invention is to propose a pulse application device that is easier to control and that makes it possible to significantly avoid accidents on the wearer and the person to be neutralized.
A second aim of the invention is to propose a pulse application device that makes it possible to modulate the intensity of the electrical pulse easily depending on the situation to be controlled.
To that end, the invention relates to a device for applying an electrical pulse including at least one glove comprising a glove body ending in glove fingers, at least three of which are provided with first application contacts, connected to an electrical energy source via a control unit, the glove further comprising second application contacts and the control unit comprising selection means for applying a differential electrical pulse between the first and second application contacts.
According to another aspect, the device comprises at least one means for securing the electrical pulse application.
Advantageously, the securing means is provided to control the application of electrical pulses under specific conditions and thus to avoid accidents.

the device comprises a bypass point of the application contacts on a palm opposite a ring finger; and/or a bypass point of the application contacts on an outer edge of a palm.
The invention will be described in more detail through the description of non-limiting embodiments and based on the appended figures.
This invention relates to a device for applying electrical pulses. This type of device is generally used in personal protection and safety applications. It is in particular a defensive device making it possible to stun an assailant. This type of device can be used by law enforcement, security personnel, or even to control dangerous patients in a psychiatric hospital.
The device comprises at least one glove 1, in particular a pair of gloves 1. Providing a device for applying electrical pulses in the form of a glove makes it possible to make it more discreet, since third parties do not know at first glance that it is a device of this type.
The glove 1 comprises a glove body 2 for receiving the base of the hand, namely the back and the palm. This glove body 2 ends in glove fingers 3, in particular at least three, preferably five glove fingers 3.
Adjustable fasteners with self-gripping strips, such as Velcro™ strips, are preferably provided on the body 2, for example at the wrists.
The device comprises an energy source 4, which here is at least one battery attached to the device. This or these batteries 4 can be positioned in a case 4A on the back face of the glove 1, corresponding to the back of a hand. The case can be made from rigid plastic, more particularly making it possible to insulate the battery 4 from water and ambient moisture and to avoid manipulations by unauthorized persons.
Said case 4A, which is preferably prismatic or cylindrical, is implanted on the back face of the glove 1 corresponding to the back of the hand, more specifically at wrist height. Advantageously, this arrangement further increases discretion, since the battery appears to be a watch at first glance. A 3.7 V and 500 mAh lithium battery can be used.
The glove 1 comprises contacts 5, 5A for applying electrical pulses, these contacts 5, 5A being connected to said source 4, more specifically through a control unit 4B.
Thus, the glove 1 includes first application contacts 5 arranged at the glove fingers 3, in particular on a front face of the glove, on the palm side of the hand. It is possible to provide these first contacts 5 at the end of these glove fingers 3, in particular on their front faces or along said front faces. The contact at the end of the glove fingers 3 is preferred, since it makes it possible to limit the size of the dangerous zone.
Advantageously, the glove 1 further includes second application contacts 5A on its front side, at the palm.
According to one variant, at least one, preferably all of the application contacts 5, 5A comprise a coating with conductive fibers, advantageously with conductive microfibers, allowing easy propagation of the electrical pulses. Furthermore, a coating with conductive fibers is easy to attach to a glove assembly, for example by sewing.
According to one aspect, the device comprises at least one, in particular several means for securing the application of electrical pulses. Advantageously, the securing means is provided to control the application of electrical pulses under specific conditions and thus to avoid accidents.
According to one variant, one of said securing means comprises a safety coating 6 on the first contacts 5 and/or the second contacts 5A for applying electrical pulses.
Thus, the device comprises an insulating coating 6 on the application contacts 5 and/or 5A. Advantageously, an insulating coating 6 makes it possible to create a controlled distance between an application contact 5 and/or 5A and the body on which the electrical pulse is applied. Thus, the invention proposes distances making it possible to secure the device by partial insulation.
The invention makes it possible to significantly reduce incidents of electrical shocks in the brain.
Furthermore, the insulating coating 6 makes it possible to hide the application contacts 5 in that they are not visible from the outside, which further improves the discretion of the taser function.
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 on top of the application contact 5 makes it possible to combine good securing with a sufficient pulse. During use with a first preferred application contact 5 with a base of conductive fibers or microfibers, a thickness of less than 0.85 mm and preferably greater than 0.65 mm, preferably equal to about 0.75 mm, yields very good results.
According to one variant, the insulating coating 6 comprises polyurethane. Advantageously, the polyurethane makes it possible to achieve the desired thicknesses and is a reinforcing material because it is a tear-resistant polymer. Furthermore, polyurethane gives an outer appearance of leather, which further strengthens the discretion of the device.
According to one variant, the device comprises at least one, preferably two bypass points 7 at least for the first application contacts 5. The bypass points 7 are connected (in particular indirectly through a control unit as will appear hereinafter) to the terminals of the battery 4 and make it possible to have, at the output, several connections to each terminal, in particular one connection for each of the glove fingers 3.
More specifically, a bypass point A+ of the positive terminal is provided on a palm opposite a ring finger. This zone is generally not very subject to mechanical stresses. Furthermore, in particular, a bypass point B− of the negative terminal is provided on an outer edge of the palm. An inverse arrangement can be considered. The bypass point B− of the negative terminal here is connected to the thumb, the middle finger and the pinky finger. The bypass point A+ of the positive terminal here is connected to the index finger and the ring finger. The bypass points can be coated with reinforcements 8. For example, a protective shell 8, which can be made from carbon fiber, is provided on the outer edge of the palm. A leather reinforcement 8a can be provided on the bypass point, for example on the bypass point A+ of the positive terminal.
According to one variant, one of said securing means comprises alternating terminals on the ends 3, which are preferably successive. The alternating terminals make it possible to create a difference in potential by a contact of several fingers. Advantageously, alternating terminals allows the user to use a finger without risk of electrocution, for example in case of itching.
In particular, said alternating terminals are done on at least three, preferably all of the successive glove fingers 3. 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 following finger, for example the index finger; then the first terminal is connected to the following finger, and so forth. Advantageously, the alternating terminals on more than two fingers make it possible to combine the application of electrical pulses with gripping.
The alternating terminals can be positive and negative terminals or a terminal and a ground. The “plus” “minus” terminals are preferred in that they are more secure, since a person in contact with the ground could be grounded and experience a discharge with a single contact not being grounded.
According to a variant, the device includes a control unit 4B configured to apply an electrical pulse to the application contacts 5 and/or 5A.
Quite particularly, the control unit 4B includes means for applying, through suitable selection means 15, a differentiated electrical pulse between the first 5 and second 5A application contacts.
Thus, this electrical pulse can have a different intensity and/or voltage at the first contacts 5 relative to that applied by the control unit 4B to the second electrical contacts 5A.
According to one preferred embodiment, the control unit 4B includes means for applying, at least to the first application contacts 5, an electrical pulse between 5 and 40 mAh, more specifically between 10 and 30 mAh depending on the charge, and preferably between 220 and 260 V, more specifically about 240 V. These values correspond to a pulse that limits damage to the body. A pulse of 240 V and 10 to 30 mAh, depending on the charge, yields better results under normal usage conditions.
Also 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 1000 volts, preferably more than 5,000 volts, advantageously on the order of 20,000 volts.
Such a high-voltage electrical pulse allows a transmission through clothing or hair of an animal to be neutralized.
The device preferably includes off and on control means 16, as it may also be equipped with a charge level indicator 9 for the battery or batteries 4 and/or an operating indicator 10, for example in the form of LEDs.
Advantageously, said case 4a incorporating the battery or batteries 4 also accommodates the control unit 4B and is preferably equipped, on its upper part, with selection means 15 and the charge level indicator 9 and/or the operating indicator 10 and/or off and on control means 16.
The entire device can weigh about 230 to 300 grams, preferably on the order of 250 to 260 grams.
Additional protective shells, which can be made from carbon fiber, are preferably provided on the glove 1. For example, a protective wrist shell 11 is provided. A protective phalanx shell 12 can also be provided, here with vents 13. Additional protectors 14, for example made from plastic, can be provided for the back part of the end of the fingers.
Also particularly to the invention, at least the glove body 2 is made from a fabric with a base of carbon fibers, withstanding cuts, particularly from poly(p-phenylene terephthalamide) (PPD-T or KEVLAR™).
During use, the glove is worn and turned on prior to using the electrical pulse application function. If applicable, the on indicator 10 is active. Through the selection means 15, the magnitude is chosen of the electrical pulse that one wishes to apply through the first 5 and/or second 5A contacts.
Thus, depending on the selection made, a pulse applied for 0.5 seconds causes pain and contracture to be felt and makes it possible to neutralize an attacker. A pulse between 1 and 3 seconds makes it possible, in some cases, to topple an attacker and to stun him for 1 to 2 minutes, with muscle pain. A pulse of about 5 seconds makes it possible to topple an attacker and stun and disorient him for more than 3 minutes, with muscle pain.
The battery 4 can be recharged in 2 hours for 8 hours of autonomy, for example.
