Description

 The invention relates to the field of locking devices and can be used in handcuffs attached to the limbs of an offender (or suspected of an offense).

 To limit the freedom of action of offenders, handcuffs are widely used, made on the basis of bracelets fastened to the offender's limbs (arms, legs). A large number of designs of such mechanical handcuffs are known. Known, for example, handcuffs containing a housing having an arched groove, cheeks connected to it, an arched grip with ratchet teeth mounted to rotate between the cheeks and moved along the arched groove of the housing, and a gripping fixation tool (RU 2005871 C1, E 05 B 75 / 00, 1994).

 However, in case of unforeseen actions of the offender, situations are possible when the handcuffs cannot ensure the unconditional safety of others and prevent the wrongful actions of the offender.

 There are known handcuffs containing two bracelets connected to each other by a hinge connected to each other by a hinge, connected to the corresponding case, inside one of which there is a power source, a receiver and an electric shock device, the output terminals of which are connected to bracelets (US 4089195, Е 05 В 75/00, 1978).

 In this device, an electric shock tool is built into traditional handcuffs. In this case, the escort can control the inclusion of the stun device. However, the inclusion of stun devices only escort limits the operational and tactical capabilities of handcuffs. In addition, such a device does not work in the mode of simple handcuffs, since it turns on as soon as the bracelets are fixed on the extremities of the offender. The device has no display elements signaling the escort, the device is turned on or off.

 Of the known devices, the closest to the claimed one is handcuffs containing two bracelets fixed to the offender’s extremities and a case connected to them with a removable cover, in the inner cavity of which there is a locking mechanism and a power supply, an electroshock device and a control unit are located (US 4811775, Е 05 В 75/00, 1989). Through the control unit, which includes the receiver, the escort can remotely control the inclusion (using the remote control located in it) of the electroshock device, which provides an electric shock through metal bracelets. The device also contains a buzzer that gives a warning sound signal at the moment of switching on the electroshock device. This increases the likelihood of the escort being safe and preventing the offender from escaping or committing violent acts against the escort and other people around him (if only because the offender is aware of their actions who was warned about the peculiarities of such handcuffs).

 However, the effectiveness of such handcuffs is also low. This is due to their limited operational and tactical capabilities, for example, when the escort was distracted, lost consciousness, or when the offender was at a distance at which the wireless connection was interrupted. Another drawback of these handcuffs is the almost impossibility of working in the mode of simple mechanical handcuffs, since the device turns on as soon as the bracelets are fixed on the hands (feet) of the offender. In addition, the absence of indication elements on the external surface of the device that could signal the mode of operation of the handcuffs at any time, can lead to the fact that the escort will not know whether the device is operating in electric mode or not.

 The objective of the invention is the creation of handcuffs, devoid of the disadvantages of the prototype. The technical result provided by the invention is to increase their efficiency by automatically turning on the electric shock mode, even if the escort for some reason does not respond to the danger (aggression) from the offender or when he tries to get rid of the handcuffs, as well as by the possibility of the device operating in the mode of simple mechanical handcuffs, when the escort does not pose a real danger to others. In addition, the invention may further enable the escort to know whether the device is ready for electric shock at a given time.

 This is achieved by the fact that in handcuffs containing two bracelets fixed on the offender’s extremities and connected to them, a case equipped with a removable cover, in the inner cavity of which there is a locking mechanism and a power source, an electric shock device and a control unit are placed, a sensor placed in the internal cavity of the case is inserted position included between the power source and the stun device, and the control unit is made in the form of an electric switch mechanically connected to a ball mechanism and connected between the power source and the stun device. The position sensor can be made in the form of a liquid electrically conductive material located in a dielectric casing, equipped with two single-level electrical contacts. The stun device can be made in the form of a pulse shaper and a step-up transformer connected to the power supply, the output terminals of which are connected to bracelets made of electrically conductive material. The handcuffs may further comprise a mode indicator located in the inner cavity of the housing, connected between the electrical switch and the position sensor.

 The above technical result is provided by the totality of the essential features.

 Figure 1 shows the structural block diagram of the inventive device; figure 2 is a structural diagram of an embodiment of a control unit with a locking mechanism; figure 3.4 - design of the position sensor (in two spatial positions); 5 is a structural block diagram of an embodiment of an electroshock device; 6 is a design of an embodiment of one part of the handcuffs (case with one of the bracelets).

 In one of the preferred structural options, the handcuffs contain a housing 1 made of a durable material, mainly steel. The housing 1 is equipped with a removable cover 2 and is mechanically connected, for example, by means of a swivel connection with bracelets 3 and 4, made mainly of alloy steel. A power supply 5, for example, a battery, an electroshock device 6, a position sensor 7, a mode indicator 8, and a control unit 9 in the form of an external key 10, for example, a mechanical switch, an electric switch 11, and a lock mechanism 12, are located 12. The lock mechanism 12 can be made both mechanical and electronic or electromechanical, including code, while the key 10 can also be made not only mechanical, but also electronic, electromagnetic, in the form of a “proximity card”, etc. The sensor is put Iya 7 is mainly made in the form of a liquid electrically conductive material 13, for example mercury, placed in a dielectric casing 15 provided with two single-level contacts 14. The electroshock device 6 is mainly made in the form of a pulse signal driver 16, consisting, for example, of a blocking generator 17, a rectifier 18 and bit block 19, and step-up transformer 20, the output terminals of which are connected to bracelets 3, 4, which are the working electrodes of the stun device 6, as well as to the protective electrodes 21, 22. The mode indicator 8 is connected between the electric switch 11 of the control unit 9 and the position sensor 7 and consists, for example, of an indication element, for example an LED, which is in optical contact with an optical element, for example, a transparent glass or plastic plate, and connected to the indication element by a control circuit ( not shown). The mechanical part of the handcuffs and the connection of the bracelets 3, 4 with the case 1 and between each other can be very different - hinged, a chain with the corresponding electric wires, etc. In this case, it is possible to use either one case 1 or two.

 The device operates as follows. After the escort puts on the bracelets 3 and 4 on the limbs of the offender, he turns on the control unit 9 by turning the key 10 or in another way, for example, using a magnetic key, entering code signals and so on. In this case, the voltage of the power supply 5 is supplied to one of the inputs of the stun device 6, while its second input remains inactive, since the position sensor 7 is in the initial (open) state (Fig. 3), which is provided at a certain (passive) position hands or feet of the offender. Hands, for example, are at the same time behind the back or in front, but always lowered down - this pose eliminates the possibility of aggressive actions. When attempting aggressive actions or the offender’s escape, his hands inevitably make sudden movements, which leads to the operation of the position sensor 7 (Fig. 4). The stun device 6, being fully connected to the power supply 5, generates a high voltage at its outputs, which is transmitted to the bracelets 3, 4 and provides an electric shock that paralyzes the offender. The parameters of the stun device circuit are selected in such a way that damage is not caused to the offender’s temporary damage to his health and life. The protective electrodes 21, 22 provide a "discharge" of electrical energy when the device is idling, so that the step-up transformer 20 and other circuit elements do not fail. If the device has a mode indicator 8 during a trial (preliminary) turning on of the device, indicator 8 indicates whether the device is ready for operation or, for example, it is necessary to replace the power supply 5. In the future, the working mode indicator 8 indicates the operating mode of the handcuffs.

 Implementation example. The handcuffs are made with a body 1 having dimensions of 100x66x26 mm. The discharge voltage between bracelets 3, 4 is 2000 V, the discharge repetition rate is 50 Hz, the discharge duration is 1 ms, and the supply voltage is 6 V. A stable electroshock effect without threatening the offender’s health is achieved with an exposure time of about 0.3 s.

 The invention provides an increase in the effectiveness of handcuffs, expanding their operational tactical capabilities, which helps prevent the offender from aggressive actions or his escape. If necessary, the handcuffs can work in the usual mechanical mode.
