Abstract:
A restraint device having a tubular body with a handle at one end and a telescopic extension rod at the other end which allows the overall length of the body to be selectively adjusted. A cuff is attached to a tether at the end of the rod in a non-deployed position. The tether can be released so a law enforcement officer can loosely control a detainee. Electrical circuitry in the body is connected to electrodes on the lower end of the handle and on the cuff so a disabling charge can be delivered. The device is also useful to civilians as a protective device when jogging, walking, bicycling or the like.

     TECHNICAL FIELD 
       [0002]    This description relates generally to a restraint device and more specifically to a device for physically restraining an individual as well as for selectively applying an electrical shock to control a combative or resistive individual or to deter or repel an attack by an individual or an animal. The device may be utilized by law enforcement personnel as well as by joggers, hikers, bicyclists, animal control officers and others. 
       BACKGROUND 
       [0003]    There are various non-lethal control, defensive or restraining devices used by law enforcement and others to restrain and control detainees or to ward off an attacker. The simplest of these restraint devices are handcuffs, manacles or shackles which have been available and have been used for many years. Manacles are placed about the wrists of an individual or, in some cases, also placed about the ankles to restrict freedom of motion. While handcuffs and manacles are effective, an individual or detainee, in some instances, can free himself or herself from these devices either by disabling the lock or by manipulation in a manner to free the wrists or ankles. 
         [0004]    More recently other devices have been developed to either restrain or temporarily incapacitate an individual. Aerosol defense sprays containing Capsicum or tear gas are well known. Stun guns use batteries to supply electricity to a circuit which includes multiple transformers which boost the voltage and reduce the amperage and which charge is stored in a capacitor. The capacitor builds up and stores the electrical charge and, upon activation, releases the charge to electrodes which is placed in contact with an individual, causing temporary interference with the individual&#39;s nervous system and muscular control to incapacitate the individual. 
         [0005]    A variation of the stun gun is the more recently developed TASER® gun. TASER® devices work in the same basic way as stun guns, except the electrodes are positioned on the end of conductive wires attached to the electrical circuit of the TASER® device. When activated, gas pressure launches the electrodes and the attached wires. Small barbs are affixed to the electrodes so that they will attach to the individual&#39;s body or clothing. Electrical current travels through the conductive wires, stunning the individual in basically the same way as a conventional stun gun. 
         [0006]    A main advantage of a TASER® device is that individuals can be brought under control at distances of up to 20 feet. Being able to maintain a distance or space between a detainee or would-be assailant, significantly decreases the risk to law enforcement personnel or intended victims. 
         [0007]    While, as mentioned above, devices such as handcuffs, manacles, shackles, aerosol spray, stun guns and TASER® guns are effective in many situations, they all inherently have certain disadvantages. Accordingly, there exists a need for an effective restraint and control device which law enforcement and other individuals can use to restrain an individual while maintaining a space between the individual and law enforcement personnel. Further, there exists the need for a device of this type which can both provide physical restraint without electrical shock or in the case of more extreme resistance by a detainee, can also apply electrical shock to temporarily disable the individual. While the device has principal application to law enforcement, the device may also be used by civilians as a protective safety device in the event of an attack or threatened attack, as well as by animal control personnel. 
         [0008]    Many of the attendant features will be more readily appreciated as the same becomes better understood by reference to the following detailed description considered in connection with the accompanying drawings. 
       SUMMARY 
       [0009]    The following presents a simplified summary of the disclosure in order to provide a basic understanding to the reader. This summary is not an extensive overview of the disclosure and it does not identify key/critical elements of the example or delineate the scope of the example. Its sole purpose is to present some concepts disclosed herein in a simplified form as a prelude to the more detailed description that is presented later. 
         [0010]    The present example provides a restraint and control device having an insulated handle at the upper or proximal end and a rod at the distal end which rod is telescopic within the handle so that the overall length of the restraint device can be adjusted. A lockable manacle or cuff is secured to the end of a tether. The manacle or cuff has a fixed arcuate section and a pivotal arm which is engageable in a lock on the fixed section to encircle the limb of an individual. The tether is a wire of stainless steel or other strong material which also serves as an electrical conductor. The end of the tether opposite the cuff is secured to a retractor within the handle. In the retracted position, the cuff is secured at the end of the telescopic rod so that the cuff and the restraint device are an integral, rigid assembly and the tether is fully retracted on to the retractor. In this position, the restraint and control device is rigid and can be attached to the limb of an individual at the cuff or manacle so the movements of the individual can be restrained and controlled by a law enforcement or other individual using the handle while still maintaining the restrained individual at a safe distance. 
         [0011]    The tether can be released to free the cuff from the end of the rod. In this deployed position, the restrained individual will have more freedom of movement, but can still be controlled while maintained at a greater distance from the law enforcement or other individual. 
         [0012]    The upper end of the handle of the restraint and control device houses a battery, transformer, capacitor and circuitry common to stun devices. This circuitry is connected to electrodes on the exterior of the distal end of the rod, as well as electrodes located within the cuff. A trigger, preferably within a trigger guard on the handle, can be operated to cause a high voltage, low amperage discharge to the electrodes which will deliver a disabling or stunning shock to the individual. The electrodes on the distal end of the rod will deter a detainee from attempting to grab the rod to wrestle it away from law enforcement personnel or other user.

       DETAILED DESCRIPTION 
       [0026]    The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functions of the example and the sequence of steps for constructing and operating the example. However, the same or equivalent functions and sequences may be accomplished by different examples. 
         [0027]    The examples below describe a restraint device. Although the present examples are described and illustrated herein as being implemented in a ankle restraint system, the system described is provided as an example and not a limitation. As those skilled in the art will appreciate, the present examples are suitable for application in a variety of different types of restraint systems applicable to various extremities, and portions of those extremities. 
         [0028]      FIG. 1  is a partial perspective view showing the cuff on the distal end of the restraint device secured about the limb of a detainee. The manacle  20 , may be secured about a limb L such as an arm or a leg. Advantageously the manacle  20  may be applied without an officer, or other user having to be in close proximity either in attaching the manacle, or after it is applied. The manacle may be made in various sizes for us with humans and animals of various sizes. Use of eh restraint and control device advantageously allows an electrical stunning device to be used without having to apply electrodes to a torso. Such electrode placement away from the torso should greatly reduce risk of heart attack in those who have had a electrical stun applied to them. 
         [0029]      FIG. 2  is a perspective view of the restraint device of the present example shown in a retracted, rigid position. The restraint and control device of the present example is shown and is generally designated by the numeral  10 . 
         [0030]    The restraint device  10  has an elongate, generally tubular body  12  having a handle  14  at its upper proximal end and a lower, distal end  16 . The handle  14  may be a strong, lightweight non-conductive material such as a fiberglass or a polymeric composite, or the like. The tubular shape may be round as shown, but this is not limiting as the tube could have a square, elliptical, rectangular or other shaped outline. 
         [0031]    At an upper end of the body  12  a handle may be disposed. The upper end of the handle  14  may be contoured having recesses  18  to receive the fingers of the user. The handle  14  may also be provided with a resilient covering, both for comfort of the user and which covering is insulated to protect the user from electrical shock. 
         [0032]    A manacle or cuff  20  is positioned at the lower end  16  of the body  12 . The manacle  20  may include a lock body  22 , preferably of the double locking type, which has internal ratchet teeth  24  operable by a key (not shown) inserted in the lock opening  26  and rotated to open the ratchet teeth  24  and release the bolt of a double locking type lock. A fixed, generally arcuate arm  30  extends from one side of the lock body and is pivotally secured to arm  32  at pivot  36 . A torsion spring  38  may be provided at pivot  36  to bias or urge the arm  32  to the open position when the arm  32  is unlocked. The distal end of arm  32  is provided with teeth  35  which are engageable with the ratchet teeth within the lock body and, in the locked position, the arm is prevented from opening and also prevented from further tightening. Handcuff locks of this type are known to those skilled in the art. 
         [0033]    When the cuff  20  is placed about the limb of an individual, as shown in  FIG. 1 , and locked, the restraint device is rigid and can be used to restrain and control the movements of an individual. The cuff  20  can be opened at key lock  26  and the arm  32  will move to the open position under the influence of the spring  38 . The user can engage the fixed arcuate section  30  about the limb of an individual and a quick, smart “snapping” wrist action will cause the locking arm  32  to be engaged in the lock so that the user does not have to bend down or come into close proximity with a restrained individual. Being able to maintain a distance from the individual to be restrained is a safety precaution and diminishes the possibility that the restrained individual can, in some manner, overcome or successfully resist restraint. 
         [0034]    The restraint device  10  can be a unitary piece, but it may advantageously be constructed as two pieces coupled by a tether that provides additional advantages in use. In the two piece unit described herein, the manacle  20  couples to the body  12  by being shaped to fit in a receiving aperture disposed in the lower end of the body  12 . The device  10  may remain rigid during application, and afterwards, if desired separated into two coupled pieces, coupled by a tether (not shown) to allow greater mobility. Separation may be accomplished by depressing a release  95 , disposed in the body  12 . 
         [0035]      FIG. 3  is a partial perspective view showing the distal end of the restraint device of the present example secured about the limb of an individual in a position with the tether deployed. Another feature of the present example is that the restraint allows the handle or body  12  to be loosely tethered to the restrained individual. In this way, the law enforcement officer or other user may maintain a greater distance from the detained individual, but still may maintain control of the detained individual. 
         [0036]    A strong tether cable  80  is connected to the cuff  20 . The cable may be a stainless steel or other wire that extends through the lower tubular elongate body  12  into the upper handle. The cable may incorporate electrical conductors  70  coupled to the electrodes  50 ,  50 A, and activated by the officer in alternative examples of the restraint and control device including a TASER®, or other equivalent stunning device. 
         [0037]    Before activation the cuff  20  may be held against a flush cut end of the tube  12 , by the cable tension, as its retraction mechanism may be under spring bias. Being held against the flush cut tube by cable tension may also be augmented by other equivalent coupling mechanisms. For example a cone may be disposed on the manacle so that it retracts and centers when pulled into the hollow center of the tube  12 . Alternatively any sort of aperture may be disposed in either the manacle  20  or tube  12  to recievabally couple to a mating surface provided on the component that will mate with it. 
         [0038]      FIG. 4  is a perspective view of the restraint device of the including a telescopic extension of the rod and of the cuff from the handle. The device may be extensible so the user may adjust the length of the body  12 . A lower rod end  16  is slidable within the tubular body  12 . The lower rod end  16  defines a longitudinally extending slot  40  in which a plurality of bores  42  are provided. A spring-loaded detent pin  46  is provided at the lower end of the handle portion which is engageable in one of the bores to lock the rod at a selected position. 
         [0039]      FIG. 5  is a perspective view of an alternative example of the restraint and control device similar to  FIG. 4 . The restraint device of the present example may also be provided with the capability of applying a high voltage, low amperage electrical charge to an individual to assist in restraining or stunning an individual who is resistive or combative. 
         [0040]    The figure shows the distal rod end retracted and the tether and cuff deployed, and further includes the rod being provided with electrodes  50  for applying a stun or electrical shock to a detainee. To provide a shock a conventional circuit such as used in an electric fence, stun gun, or TASER® may be utilized, as in this example by including it in the body  12 . 
         [0041]    The electrical circuit  60  is connected via at least two conductors  70  to the electrodes  50  and, upon discharge, activated by a trigger  55  on the handle will send the electrical charge to the electrodes. The conductors  70  are contained within tether  80  or the tether  80  itself may serve as the conductor between the electrical circuit and the electrodes. 
         [0042]    Additional electrodes  50 A may also be located on the inner side of the arms of the cuff and are shown as fixed arms  30 . A safety may be provided to lock the trigger  55  and prevent inadvertent discharge. The safety is conventionally constructed like a pushbutton safety on a firearms, as is well known to those skilled in the art. Alternatively other types of trigger locks may be used as safety&#39;s including bales latches and the like. The charge delivered to the electrodes  50 A on the cuff from the circuit  60  will stun the restrained detainee. The electrodes  50  on the lower end of the body  12  of the device can be placed in contact with an unrestrained individual to subdue the individual. The electrodes  50  will also hold to fend off a restrained individual from attempting to grab the device and wrest it from law enforcement personnel or other user. 
         [0043]      FIG. 6  is a sectional view taken along line  6 - 6  of  FIG. 4  and shows the detent pin  46  in an engaged position in one of the bores  42 . The telescopic lower rod end  16  may also be adjusted by other convenient mechanisms such as an adjustable locking slip collar or the like. The body may also be non-adjustable having a fixed length either longer for law enforcement personnel or shorter for civilian use. 
         [0044]      FIG. 7  is a sectional view taken along line  7 - 7  of  FIG. 5  and shows electrodes  50  disposed on the body  12 . The body  12  can be provided with two or more pairs of electrodes  50 . However, any number of electrodes, and patterns of electrodes are contemplated, two electrodes typically being a minimum number provided. 
         [0045]      FIG. 8  is a schematic diagram showing the components of the electrical circuit  60  that may be housed within the handle of the restraint device shown in  FIG. 5 . The electrodes previously shown may be coupled to an electrical circuit  60  within the handle. The electrical is a stunning circuit, conventionally constructed and may include a battery  62 , voltage amplifier  64  and a capacitor  66  or their equivalents, which are conventional to stun guns and other devices such as TASER® devices. In addition a conventionally constructed wireless receiver and antenna  67  and associated circuitry may be included in the circuit to allow remote activation of the stunning circuit  60 . 
         [0046]      FIG. 9  is a detail view of the handle broken away to illustrate the retractor in the handle of the device for deploying and taking up the tether. The spool can be unlocked allowing the spring-biased spool to rewind the cable to return the cuff to the position shown in  FIG. 2 . The user can allow the spool to fully rewind the tether, placing the cuff in a secured position at the lower end of the body. 
         [0047]    The upper end of the body ( 12  of  FIG. 2 ) houses a spring-loaded retractor spool  90  upon which the cable  80  is wound. Spring  92  will urge the spool in a direction to wind the cable on the spool. When the law enforcement officer or other user wishes to deploy the cable, a shaft acting as a release  95  will disengage the teeth on the ratchet  98  from the teeth  96  on the spool, allowing the spring-biased spool to freely rotate to pay out or deploy cable  80  when the handle is pulled and the tether cuff engaged about the limb of an individual. Thus, the user can allow the connecting tether cable to extend to a desired length at which point the spool will be locked by ratchet teeth  98  engaging the release maintaining the cable at the desired length in a taut condition. 
         [0048]    Tether  80  is unwound from spool  90 , which may include spring bias by biasing spring  92 . Spring bias is conventionally supplied for taking up the tether, or otherwise retracting it. A ratcheting mechanism is provided by teeth  86  on the edge of spool  90 . Spool teeth may engage with a toothed spool  98 , so that as the tether  80  is extended it is not automatically retracted. The tether may be retracted by pushing an exposed end of shaft  95  that is slidebally disposed in apertures in the handle  12 . Spring bias (not shown) may be provided to return the spool  98  to position. Other equivalent structures for deploying and retracting the tether  80  may be provided that function as described herein. 
         [0049]    The tether  80  may have the conductors  70  disposed on it, or otherwise coupled to it, along its length so that when the tether plays off of the spool the conductors go with it. The conductors may be on the inside, or outside of the tether, or may be incorporated in the tether itself. For example with conductors on the interior the tether may be a woven tubular cable with the insulated conductors included in its core. If on the outside the conductors may be bonded or otherwise coupled to the tether. The tether may be made from any suitable conductive material like a steel braided cable, nonconductive material such as nylon cord, or a combination of materials or their equivalent. 
         [0050]    Conductors  70  may be wound on a spool behind spool  90 , and wound in the opposite direction to the tether  80  so that they unwind into the hollow handle when the tether is extended. This maintains the high voltage connection to the electronics ( 60  of  FIG. 8 ) disposed in the handle. Alternatively a contactor arrangement, with brushes or the like may couple the electrical signals from the electronics ( 60  of  FIG. 8 ) to the conductors  70  that have been incorporated into the tether  80 . 
         [0051]    Alternatively the conductors  70  may deploy separately from the tether  80  with their own deployment mechanism such as spring wire wound under tension so that the wires tend to quickly play off of a spindle upon which they are wound. Other known equivalent retractor mechanisms including a manually windable retractor spool can be used in alternative examples. 
         [0052]      FIG. 10  shows an alternative example of a wireless controlled restraint and control device. In this example a need for conductors extending from the handle is eliminated as the electronic circuit  60  is part of the previously described cuff  20 . Electrodes  50 A are activated by the trigger  55  activating conventionally constructed transmitter electronics in the body  12  that are coupled wirelessly  1001  to an antenna and receiver electronics that are coupled to the electronic circuit  60 . Optionally electrodes  50  may be incorporated into the body, with an additional electronic circuit (not shown, but as previously described) to create a stun baton after deployment of the cuff  20 . The previously described tether release  94  may be used in this example to release the cuff  20  from the body  12 . Alternatively the tether ( 80  of  FIG. 3 ) may be included to provide added control. 
         [0053]    In another alternative example, in the case of a detachable cuff having a wireless ling as shown in  FIG. 10 , two cuffs may be included in the device-one at each end, increasing it usefulness for example in riots and crowd control. Controls and circuitry are duplicated as needed to control the additional cuff. 
         [0054]      FIG. 11  is a perspective view of the restraint device of the including a compound telescopic extension of the rod and of the cuff from the handle. The device may be extensible so the user may adjust the length of the body  12 . A lower rod end  16  is slidable within the tubular body  12  in two locations allowing quick deployment. The lower rod end  16  longitudinally extends, and the piece having the catch  46 , also moves away from the body  12  as it extends to an open position. 
         [0055]    It will be obvious to those skilled in the art to make various changes, alterations and modifications to the example described herein. To the extent such changes, alterations and modifications do not depart from the spirit and scope of the appended claims, they are intended to be encompassed therein. 
         [0056]    Those skilled in the art will realize that the process sequences described above may be equivalently performed in any order to achieve a desired result. Also, sub-processes may typically be omitted as desired without taking away from the overall functionality of the processes described above.
