Adjustable length cable lock and package locking device, system, and method

An adjustable length cable lock device, for use with a portable item and a fixed object, comprising:

• a) an elongate first cable having a first securing end portion and a secured end portion, and an elongate second cable having a second securing end portion and a handle end portion, with the first cable and the second cable adapted to together extend in a cable loop about the portable item, and with the handle end portion having a handle adapted to be pulled to tighten the cable loop about the portable item;
• b) a locking mechanism which securely locks the first and second securing end portions to each other in a locked configuration, and which is selectively unlockable to permit removal of the first and second securing end portions from each other;
• c) a cable tightening device which:
• (i) has a selectively actuable release mechanism;
• (ii) securely engages the second cable while still permitting longitudinal movement of the second cable relative thereto, with said longitudinal movement permitted only in a tightening direction unless the release mechanism is selectively actuated;
• and (iii) defines a cable passage therethrough, with the second cable slidably extending through the cable passage and securely engaged by the cable tightening device;
• and
• d) an affixing member secured to the cable tightening device and the secured end portion of the first cable, with the affixing member for securing to the fixed object such that the first cable and, via the cable tightening device, the second cable are then secured to the fixed object;
• wherein, in the locked configuration, said movement in the tightening direction operatively tightens the cable loop about the portable item towards a secured configuration;
• and
• wherein, in the secured configuration, the cable loop engages and secures the portable item against the fixed object, such that the portable item thus secured prevents access to the release mechanism, with the aforesaid selective unlocking of the locking mechanism permitting removal of the portable item from the cable loop and ready access to the release mechanism.
