Abstract:
1. A restraint device comprising a first bracelet having a pivot and an upper section having a series of ratchets at an end thereof which is opposite the pivot; a central holder; and a second bracelet, wherein the central holder contains a locking/unlocking mechanism having pawls which interlock with the ratchets of the first bracelet, a pivotable press lever mechanism having a first side which abuts with the first bracelet's ratchets, a pivotable one-way locking mechanism having a pawl, and a retraction/extension mechanism having gears and a first end of a line having first and second ends operatively attached thereto, wherein the second end of the line is operatively attached to the second bracelet, and wherein the parts are so arranged that (1) when the first bracelet is open the ratchets of the first bracelet do not operatively engage with the pawls of the locking/unlocking mechanism and the ratchets of the first bracelet do not urge the press lever mechanism, the press lever mechanism pivots in response to a spring action to press downwardly on the one-way locking mechanism to cause the one-way locking mechanism to pivot and disengage the pawl of the one-way locking mechanism from the gears of the refraction/extension mechanism, and the retraction/extension mechanism may either retract or extend the line and (2) when the first bracelet is closed, the ratchets of the first bracelet operatively engage with the pawls of the locking/unlocking mechanism and the ratchets of the first bracelet urge the press lever mechanism, the press lever mechanism is pivoted away from the one-way locking mechanism, the one-way locking mechanism pivots by spring action so that the pawl of the one-way locking mechanism engages with the gears of the retraction/extension mechanism preventing extension of the line but allowing refraction of the line.
