Description

SECURE DEVICE FOR APPLYING AN ELECTRICAL PULSE

The présent invention relates to a device for applying an electrical puise of the type generally used in applications for personal protection and safety. It in particular relates to a défensive 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 puises to attackers or individuals deemed dangerous in order to neutralize them.

Lnfortunately, this type of device generally applies uncontrolled electrical puises 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 électrodes made from conductive fabric connected to an appropriate electrical power supply. These électrodes 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 puise 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 puise application device that makes it possible to modulate the intensity of the electrical puise easily depending on the situation to be controlled.

To that end, the invention relates to a device for applying an electrical puise 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 sélection means for applying a differential electrical puise between the first and second application contacts.

According to another aspect, the device comprises at least one means for securing the electrical puise application.

Advantageously, the securing means is provided to control the application of electrical puises under spécifie conditions and thus to avoid accidents.

According to other aspects considered alone or combined according to ail technically possible combinations:

said securing means comprises alternating terminais on the preferably successive ends; and/or the alternating of terminais is done on at least three successive ends; and/or said securing means comprises a safety coating on the electrical puise application contacts; and/or the safety coating comprises polyuréthane; and/or the safety coating has a thickness on top of 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; still more preferably equal to about 0.75 mm; and/or at least one application contact comprises conductive microfibers; and/or the control unit includes means for applying, on the first application contacts, an electrical puise 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; and/or the control unit includes means for applying, on the second application contacts, a high-voltage electrical puise greater than l ,000 volts, preferably greater than 5,000 volts, more specifically on the order of 20,000 volts;

the device comprises said energy source, which is at least one battery attached on a back face of the glove; and/or 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, in which:

figure l is a planar view of a front face of the device according to one preferred variant of the invention;

figure 2 is a view similar to that of figure l illustrating the electrical assembly of said device; and figure 3 is a spatial view of a back face of the device of figures l and 2.

The invention relates to a device for applying electrical puises. This type of device is generally used in personal protection and safety applications. It is in particular a défensive 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 psychiatrie hospital.

The device comprises at least one glove 1, in particular a pair of gloves 1. Providing a device for applying electrical puises 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 discrétion, 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 puises, 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 ail of the application contacts 5, 5A comprise a coating with conductive fibers, advantageously with conductive microfibers, allowing easy propagation of the electrical puises. 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 puises. Advantageously, the securing means is provided to control the application of electrical puises under spécifie 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 puises.

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 puise 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 15 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 discrétion 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 20 the application contact 5 makes it possible to combine good securing with a sufficient puise. 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 polyuréthane. Advantageously, 25 the polyuréthane makes it possible to achieve the desired thicknesses and is a reinforcing material because it is a tear-resistant polymer. Furthermore, polyuréthane gives an outer appearance of leather, which further strengthens the discrétion 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 30 through a control unit as will appear hereinafter) to the terminais of the battery 4 and make it possible to hâve, 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 35 particular, a bypass point B- of the négative terminal is provided on an outer edge of the palm. An inverse arrangement can be considered. The bypass point B- of the négative 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 40 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 terminais on the ends 3, which are preferably successive. The alternating terminais make it possible to create a différence in potential by a contact of several fingers. Advantageously, alternating terminais allows 45 the user to use a finger without risk of electrocution, for example in case of itching.

In particular, said alternating terminais are done on at least three, preferably ail 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 terminais on more than two fingers make it possible to combine the application of electrical puises with gripping.

The alternating terminais can be positive and négative terminais or a terminal and a ground. The “plus” “minus” terminais are preferred in that they are more secure, since a person in contact with the ground could be grounded and expérience a discharge with a single contact not being grounded.

According to a variant, the device includes a control unit 4B confîgured to apply an electrical puise to the application contacts 5 and/or 5A.

Quite particularly, the control unit 4B includes means for applying, through suitable sélection means 15, a differentiated electrical puise between the first 5 and second 5A application contacts.

Thus, this electrical puise can hâve 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 puise 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 puise that limits damage to the body. A puise 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 puise of more than 1000 volts, preferably more than 5,000 volts, advantageously on the order of 20,000 volts.

Such a high-voltage electrical puise allows a transmission through clothing or haïr 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 accommodâtes the control unit 4B and is preferably equipped, on its upper part, with sélection 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 puise application function. If applicable, the on indicator 10 is active. Through the sélection means 15, the magnitude is chosen of the electrical puise that one wishes to apply through the first 5 and/or second 5A contacts.

Thus, depending on the sélection made, a puise applied for 0.5 seconds causes pain and contracture to be felt and makes it possible to neutralize an attacker. A puise between 1 and 3 seconds makes it possible, in some cases, to topple an attacker and to stun him for l to 2 minutes, with muscle pain. A puise 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.
