A restraint device and associated method for securing the wrists of a subject, the device comprising a first wrist restraint and a second wrist restraint, each wrist restraint having a loop with a variable circumference, wherein each wrist restraint transitions between an inserting configuration, and a secure configuration, wherein the circumference of the loop in the inserting configuration is greater than the circumference of the loop in the secure configuration, and a cinching portion couplable to each wrist restraint to removably attach the first wrist restraint and the second wrist restraint, wherein upon increasing a distance between a first wrist of the subject inserted into the loop of the first wrist restraint, and a second wrist of the subject inserted into the loop of the second wrist restraint, the restraint device transitions from the inserting configuration to the secure configuration.

An apparatus and a method of constructing an apparatus are disclosed including a plurality of wristlets, a plurality of handles, a plurality of lines constructed of flexible material and attached to the plurality of wristlets at a first end and attached to the plurality of handles at a second end, and at least one tightening member movably attached to the plurality of lines wherein displacing at least one of the plurality of handles away from each other and with respect to the at least one tightening member moves the plurality of wristlets closer together.

The present invention generally relates to system and method of restraint for use in pulling an uncooperative detainee into and out of a vehicle. The system uses a removable body strap affixed to the detainee, which is then connected to one or more ratcheting straps that are in turn connected to one or more fixed anchors within the interior of a vehicle. When in use the system may be used to pull a detainee into the vehicle and secure the detainee in an upright position for transport.

The proposed handcuff in the invention employs an innovative locking mechanism, which stops further tightening of the handcuff when the force applied on the wrist of hand or ankle of foot is greater than 1.5 lbs (or any preset value), and prevents physical injuries from over-tightening without compromising the restrain. The handcuff is 50% faster in restraining by automatically locking instead of manually push-to-locking. The handcuff has the same shape/size/cost of the handcuffs currently used by police officer, and is compatible with current training procedure or SOP.

A restraint device tailored for law enforcement and military applications. The utility device has a tape section, a handle, and a head. The handle is connected to a proximal end of the tape section and the head is connected to a distal end of the tape section. The restraint device is provided in an expanded state that defines a loop, in which the tape section passes through an aperture in the head. Ideally, the tape section includes a stop that restricts the tape section from freely traveling through the aperture in the head. The handle preferably comprises a fastening point, which accommodates connecting the handle of the restraint device to another object. Some embodiments of the fastening point include a spring-loaded gate. The restraint device is a compact, portable, and versatile tool capable of facilitating a wide range of law enforcement and military practices.

One variation of a self-locking tie cord comprises a) a linear series of a plurality of nodules coupled together by a connective stem; b) a planar lock coupled to one end of the connective stem and comprising a valve configured to allow the nodules to pass through the planar lock in only a first direction orthogonal to the plane of the planar lock; and c) an unlocking mechanism disposed within the planar lock and configured to unlock the valve when activated, such that the nodules are allowed to pass through the planar lock in both the first direction orthogonal to the plane of the planar lock and a second direction orthogonal to the plane of the planar lock and opposite to the first direction orthogonal to the plane of the planar lock.
