Claims28
A time limited restraint device for restraining a person, comprising:
- an elongated and flexible restraint member that is constructed and arranged as an annular member of a desired circumference to restrain a person by sliding an end of said elongated and flexible restraint member through an attachment member of said elongated and flexible restraint member in a first direction, whereupon reversal of the direction of sliding of said first end relative to the attachment member is inhibited as said attachment member grasps said elongated and flexible restraint member and holds the elongated and flexible restraint member in position upon attempted reversal of direction of sliding of said elongated and flexible restraint member from said first direction, and wherein, when the elongated and flexible restraint member is formed as an annular member, the elongated and flexible restraint member is constructed and arranged to retain a wrist or ankle of a restrained person, a cutter that is positioned in proximity to the elongated and flexible restraint member when the elongated and flexible restraint member is positioned to retain the wrist or ankle of the restrained person, wherein the restraint member is threaded through the cutter
- a timer, and
- an actuator that forces said cutter against said elongated and flexible restraint member upon receiving a signal from said timer, whereupon said cutter severs said elongated and flexible restraint member.
A time limited restraint device for restraining a person, comprising:
- an elongated and flexible restraint member that is formed as an annular member and said annular member is constructed and arranged to receive and retain a wrist or ankle of a restrained person therein,
- a slidable cutter comprising a blade on an end thereof, wherein said blade is positioned proximally to said elongated and flexible restraint member when said annular member is constructed and arranged to receive and retain a wrist or ankle of a restrained person therein, wherein the restraint member is threaded through the cutter
- a timer, and
- an electrically actuated explosive charge that, upon receiving an electrical signal initiated by said timer, explodes said explosive charge and advances said slidable cutter to slide against and through said elongated and flexible restraint member upon receiving a signal from said timer, whereupon said blade of said cutter severs said elongated and flexible restraint member as said cutter slides against and through said elongated and flexible restraint member.
