DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially toFIGS. 1-4, a lock device for a notebook computer in accordance with the preferred embodiment of the present invention comprises a fixing seat10having an inside formed with a receiving chamber11and an end face formed with an elongated slot13connected to the receiving chamber11, two overlapping locking members20pivotally mounted in the receiving chamber11of the fixing seat10and each having a first section formed with a locking portion21protruding outwardly from the elongated slot13of the fixing seat10and a second section formed with a driven portion22, and a lock unit5including a housing50mounted on the fixing seat10and a lock core51rotatably mounted in the housing50and provided with a drive member52engageable with the driven portions22of the locking members20to drive the locking members20so that the drive member52of the lock core51is rotatable between a first position where the driven portions22of the locking members20are pressed by the drive member52of the lock core51, and the locking portions21of the locking members20intersect each other and a second position where the driven portions22of the locking members20are released by the drive member52of the lock core51, and the locking portions21of the locking members20overlap each other.

The end face of the fixing seat10is formed with two outwardly extending protruding plugs12, and the elongated slot13of the fixing seat10is located between the protruding plugs12. The inside of the fixing seat10is formed with two opposite receiving grooves111located at two opposite sidewalls of the receiving chamber11and two receiving channels112each connected between the elongated slot13and a respective receiving groove111. The receiving channels112of the fixing seat10are arranged in a staggered manner, and each of the receiving channels112of the fixing seat10is perpendicular to the respective receiving groove111. Each of the receiving grooves111has a substantially arc-shaped cross-sectional profile and extends in an axial direction of the fixing seat10.

Each of the locking members20has a substantially L-shaped cross-sectional profile and has a mediate section formed with a pivot portion24pivotally mounted in the receiving chamber11of the fixing seat10and formed with a pivot hole23, and the lock device further comprises a pivot shaft14extended through a peripheral wall of the fixing seat10and the pivot hole23of the pivot portion24of each of the locking members20so that the pivot portion24of each of the locking members20is pivotable about the pivot shaft14. The pivot portion24of each of the locking members20is located between the locking portion21and the driven portion22.

The locking portions21of the locking members20are located between the protruding plugs12of the fixing seat10. The locking portion21of each of the locking members20has a distal end formed with a locking hook211which protrudes outwardly from the elongated slot13of the fixing seat10and extends in a direction opposite to that of the driven portion22, and the locking hooks211of the locking members20face each other.

The driven portions22of the locking members20are directed to opposite directions. The driven portion22of each of the locking members20is mounted in a respective receiving channel112of the fixing seat10. The driven portion22of each of the locking members20is perpendicular to the locking portion21and has a first side formed with a protruding driven block221which extends in a direction opposite to that of the locking portion21and is directed toward the drive member52of the lock unit5, and the lock device further comprises two elastic members30each mounted in a respective receiving groove111of the fixing seat10and each biased between the end face of the fixing seat10and a second side of the driven portion22of a respective locking member20to push the driven portion22and the driven block221of the respective locking member20toward the drive member52of the lock unit5.

The lock core51of the lock unit5is operated by a key60to rotate the drive member52. The drive member52of the lock core51is located between the driven blocks221of the locking members20and has a peripheral wall provided with two opposite arc-shaped press portions520and two opposite flattened release portions522located between the press portions520.

Thus, when the drive member52of the lock core51is rotatable to the first position, each of the press portions520of the drive member52is movable to press the driven block221of the respective locking member20and to pivot the respective locking member20so that the locking portions21of the locking members20are movable toward each other to intersect each other, and the locking hooks211of the locking members20are movable toward each other until the locking hooks211of the locking members20are projected outwardly relative to each other as shown inFIG. 5.

On the contrary, when the drive member52of the lock core51is rotatable to the second position, each of the release portions522of the drive member52is movable to release the driven block221of the respective locking member20, and the driven portion22of each of the locking members20is pushed toward the drive member52of the lock unit5by a restoring force of the respective elastic member30to pivot each of the locking members20so that the locking portions21of the locking members20are movable outwardly relative to each other, and the locking hooks211of the locking members20are movable outwardly to overlap each other as shown inFIG. 4.

The housing50of the lock unit5has an end portion formed with a protruding insert500inserted into the receiving chamber11of the fixing seat10and has an outer wall formed with a retaining groove53.

The lock device further comprises a mounting ring40mounted in the retaining groove53of the housing50and clamped between the housing50of the lock unit5and the fixing seat10, and an extension cable42having a first end secured to the mounting ring40by a connector41and a second end provided with a loop43(seeFIG. 6).

In operation, referring toFIGS. 4-6with reference toFIGS. 1-3, the extension cable42is received through a leg81of a table80and passes through the loop43so that the extension cable42is bound onto the leg81of the table80as shown inFIG. 6. Then, the fixing seat10is mounted onto a notebook computer70placed on the table80, and the protruding plugs12of the fixing seat10are inserted into a locking hole71of the notebook computer70.

In such a manner, when the drive member52of the lock core51is rotatable to the first position as shown inFIG. 5by rotation of the key60, each of the press portions520of the drive member52is movable to press the driven block221of the respective locking member20and to pivot the respective locking member20so that the locking portions21of the locking members20are movable toward each other to intersect each other, and the locking hooks211of the locking members20are movable toward each other until the locking hooks211of the locking members20are projected outwardly relative to each other to lock two opposite sides of the locking hole71of the notebook computer70. Thus, the notebook computer70is locked onto the table80by the lock device to prevent the notebook computer70from being stolen.

On the contrary, when the drive member52of the lock core51is rotatable to the second position as shown inFIG. 4by rotation of the key60, each of the release portions522of the drive member52is movable to release the driven block221of the respective locking member20, and the driven portion22of each of the locking members20is pushed toward the drive member52of the lock unit5by a restoring force of the respective elastic member30to pivot each of the locking members20so that the locking portions21of the locking members20are movable outwardly relative to each other, and the locking hooks211of the locking members20are movable outwardly to overlap each other as shown inFIG. 1to unlock the two opposite sides of the locking hole71of the notebook computer70. Thus, the notebook computer70is unlocked from the lock device and can be carried away from the table80.

Accordingly, the notebook computer70is locked onto a fixture, such as a table80or the like, by the lock device to prevent the notebook computer70from being stolen easily. In addition, the notebook computer70is locked by or unlocked from the lock device by rotation of the key60, so that the lock device is operated easily and quickly, thereby facilitating a user operating the lock device. Further, the lock device is used to lock the locking hole71of the notebook computer70so that the lock device will not interfere with operation of the notebook computer70.
