A lock device of a plurality of two-way travel drawers of a support body, comprising in combination:
- a plurality of pegs each disposed on one side of one of the two-way travel drawers;
- a plurality of two two-way travel slides each disposed on an outer surface of either side of one of the two-way travel drawers;
- a lock assembly longitudinally mounted on one side of the support body and comprising a groove member, a sliding member, a biasing member, a lock, and a plurality of snapping members wherein the groove member includes front and rear flanges and an upward bend on an upper portion proximate to the rear flange;
- the sliding member is disposed in the groove member and includes an upper hook, and two opposite upright retaining members on tops of front end rear edges respectively, each of the retaining members having a second through hole;
- the biasing member interconnects the bend and the hook so that the sliding member is capable of sliding about the groove member;
- the lock is disposed on an upper portion of an inner surface of one side of the support body for stopping the sliding member from moving out of its confined range;
- and each of the snapping members includes two latches on front and rear ends respectively, the latches secured to the sliding member, a central trough on a bottom, and two curved surfaces each extending from the trough to either latch;
- and
- a positioning assembly comprising two links, two bending members, two biasing elements, and two triggers wherein the link includes a first enlargement proximate to a first end, an intermediate second enlargement, an extension extending inward from the second enlargement, an inclined section interconnecting the extension and a second end;
- the bending member secured to the inner surface of one side of the support body and includes a vertical section having a third through hole;
- the first end is moveably disposed through a rear surface or a front surface of the support body;
- each of the triggers is disposed on the first end and spaced from the rear surface or the front surface of the support body;
- each of the biasing elements is put on the extension and anchored between the second enlargement and the vertical section of the bending member;
- and the second end passes through the third through hole of the vertical section of the bending member to be proximate to the lock with both the inclined section and a portion of the extension disposed between the vertical section of the bending member and the retaining member;
- and the first enlargement is stopped by the rear surface or the front surface of the support body in an inoperative position;
- wherein the locking device is capable of operation such that, when one trigger is pushed and compresses the corresponding biasing element, the corresponding inclined section inserts through the second through hole of the corresponding retaining member to lift one of the snapping members, and the trough of the snapping member disengages from the corresponding one of the pegs, thereby unlocking one of the two-way travel drawers.
