Abstract
A law enforcement restraint device consisting of an implement handle and hollow shaft containing two or more collapsed, deployable, and detachable locking cuffs. The shaft is long enough for a law enforcement officer to safely apply the restraint device to a violent, mentally ill, or non-compliant detainee. A handle trigger allows for the exposure of an uncollapsed open locking cuff at the end of the shaft, ready for deployment to the detainee. Another trigger within the cuff automatically causes the locking of the detachable cuff about the limb of the detainee once the trigger is depressed by contact with the detainee limb. A flexible cable attached to the first locked cuff causes the exposure of a second locking cuff to the deployable position at the end of the shaft when the shaft is pulled away from the detainee. Following the deployment of two cuffs to two limbs of the detainee, pulling the shaft away from the detainee shortens the distance between the cuffs and further restrains the detainee. Pulling the shaft away from the detainee further releases the end of the cable from the handle and shaft. A key is used to release the clamp that tightens the cable and to release the cuffs from the locked position. Following the release of the detainee, the locking cuffs can be collapsed and reloaded along with the connecting cable into the shaft of the device for repeated use.

Detailed Description—FIGS. 1, 2, 3, 4, 5, 6—Preferred Embodiment
[0016] A preferred embodiment of the law enforcement restraint device is depicted in FIG. 1, FIG. 2, FIG. 3, and FIG. 4 (in use), and FIG. 5 and FIG. 6 (telescoped views showing internal components).
[0017] With reference to FIG. 1, the law enforcement officer 10 informs a detainee 12 that the restraint device 14 will be deployed for non-compliance with instructions for being arrested. As with a baton or hand cuffs, the restraint device is meant to be a portable item that can be worn on a belt 16 or otherwise detachably clipped to a uniform. In the preferred embodiment, with reference to FIG. 2, the restraint device consists of a handle 18 with hollow shaft 20 that contains collapsed locking cuffs and is long enough to safely apply the cuffs to the uncooperative detainee. A handle trigger 22 exposes at the end of the hollow shaft an uncollapsed and detachable locking cuff 24 in a deployable open position that can then be applied to a limb 26 of the detainee. With reference to FIG. 3, the applied and detached first cuff is connected by a flexible cable 28 to a second detachable locking cuff 30 that is drawn from a collapsed position within the hollow shaft of the handle to the opened deployable position at the end of the shaft by pulling the handle and shaft away from the detainee, who is already bound by the first detachable locking cuff. The second detachable locking cuff can then be applied to a second detainee limb 32 in the same manner as the first detachable locking cuff. With reference to FIG. 4, pulling the handle away from the detainee after applying the second cuff causes the flexible cable between the two cuffs to be tightened, thereby further binding the detainee.
[0018] With reference to FIG. 5 and a detailed cross-section view of the loaded restraint device, a slot in the handle allows for the trigger to rotate about a hinge pin 34 and is kept in place at rest via a trigger spring 36. When pulled, the trigger releases the barb of a spring catch 38, allowing the main shaft spring 40 to be released from a cocked position. A trigger channel 42 in the handle and hollow shaft ensures that the barbed spring catch does not obstruct other internal components of the cylinder of the hollow shaft. The main shaft spring is attached to the spring catch disc plate 44, and a separate rear spring plate 46 also serves as one wall of the chamber housing the trigger. The length of the main shaft spring is set so that its release results in the forward movement of the entire assembly of locking cuffs through the hollow shaft until the first detachable locking cuff is forced from the first catch position 48 to the second catch position 50. The flexible cable that joins the two locking cuffs has a plunger 52 that connects to the spring catch disc plate via a plunger knob 54 which can be forcibly pushed through the deformable spring catch disc plate, with a plunger rear plate 56 preventing it from being forced past the spring catch disc plate. The plunger front plate 58 is flush to the base of the second collapsed deployable and detachable locking cuff in the assembly when loaded, and in turn the front of the second collapsed deployable and detachable locking cuff is flush to the base of the first collapsed deployable and detachable locking cuff in the assembly when loaded. The front end of the flexible cable is secured to the base of the first collapsed deployable and detachable locking cuff via a front cable knob 60 that prevents its release. A cable stop 62 sets the maximum distance that the two cuffs can be apart, and further ensures that by pulling on the shaft after the first cuff is deployed, that the second cuff will be forcibly moved forward to the front deployable position at the end of the hollow shaft. Two cuff channels 64 in the hollow shaft of the device ensure that the collapsed deployable and detachable locking cuffs are set to the uncollapsed and deployable position at the front of the shaft in a predictable orientation to facilitate use, preferably perpendicular to the trigger shaft (although the trigger channel is shown as synonymous with one of the cuff channels in FIG. 5 for simplicity), and further to accommodate the size of the cuffs without increasing the overall diameter of the shaft to an unmanageable size. The cuff channels also further ensure that the arms of the cuffs are spaced apart correctly and are not accidentally locked closed when loading or reloading the components into the shaft.
[0019] With reference to FIG. 6 and a detailed cross-section view of the locking cuff, a cuff trigger 66 resides within the opened deployable cuff to cause the cuff to be forcibly locked and closed about the limb of the detainee when depressed, and simultaneously activates the release of the cuff from the end of the hollow shaft, via a system of cogs and toothed elements. In the preferred embodiment, each arm of the cuff has a hinged end mounted to a cuff base 68 that houses the internal components of the cuff. A cuff trigger spring 70 causes the forward positioning of the trigger and the simultaneous opening or uncollapsing of the cuff arms when exposed past the end of the hollow shaft. Middle cogs 72 articulate with the cogs of the cuff arms and toothed sections of cuff catches 74 that hold the cuff in the deployable position at the second catch position at the end of the hollow shaft. The second catch position is much larger than the first, so that only a slight expansion of the cuff catches and cuff arms is necessary to secure the first cuff when loading or reloading. Two catch springs 76 on either side of a cylinder containing the cuff trigger spring facilitate the positioning of the cuffs to the deployable position when forced forward by either the handle trigger in the case of the first cuff, or pulling the shaft away from the detainee in the case of the second cuff. The cogs on the cuff trigger articulate with cogs on the end of the cuff arms, so that when the trigger is depressed by forcibly being pushed against the limb of the detainee, the deployable cuff is forced fully closed and locked via a trigger lock 78. When the cable is pulled after the application of the second cuff to the detainee, the distance between the cuffs is shortened and a locking clamp 80 in the second cuff prevents loosening. A key 82 is used to loosen the locking clamp and release the cuffs locked by the trigger lock when appropriate. The unlocked, collapsed cuffs and connecting cord can be reinserted and loaded into the end of the shaft for future redeployment.
[0020] The preferred embodiment of FIGS. 1, 2, 3, 4, 5, and 6 shows aspects of the invention related to ease of use and safe application. Other embodiments could also be derived to accomplish these same goals. In alternative embodiments, more than two cuffs could be available to decrease the potential mobility of the detainee to resist or flee, and could also be used to bind more than one detainee together. Further, instead of a cuff trigger to apply and release the locking cuff, a handle trigger could be used to shoot a cuff towards the detainee as a projectile where a greater need for safety distance is necessary. In the preferred embodiment, the detachable locking cuffs are constructed of a rigid material such as stainless steel, while in the alternative embodiments, a more flexible material effectively serving as a slap bracelet could be used. In the preferred embodiment, an ideal length of the handle shaft is set to provide safety to the law enforcement officer, while alternative embodiments can include retractable or extendable shafts selected for particular arrest situations. In another alternative embodiment, the locking of the cuffs activates an internal GPS device that allows for law enforcement to track the detainee in the event of flight during or after the application of the cuffs. In yet another alternative embodiment, the trigger contains a sedative to further immobilize the uncooperative detainee.
