Abstract

A cable combination lock includes: a lock body (1) having a plurality of dials and sleeves rotatably mounted in the lock body, a locking bolt (2) insertable and lockable in the lock body (1), a cable (3) having a first cable end (31) secured with the locking bolt (2) and a second cable end (32) formed as a cable ring (33), and at least a fastener (4) secured on a portable computer or the other object to be locked; whereby upon insertion of the locking bolt (2) through the fastener (4) and through the cable ring (33) of the cable (3) to be locked in the lock body (1), and upon fastening of the cable (3) on a fixture, the computer or the object will be safely locked and fastened to the fixture.

Claims

1. A cable combination lock comprising;

a lock body (1) having a plurality of dials (14) and sleeves (13) rotatably mounted in said lock body (1);

a locking bolt (2) insertable and lockable in said lock body (1) by operating said dials (14) and sleeves (13) to a locking combination;

a cable (3) having a first cable end (31) secured with said locking bolt (2) and having a second cable end (32) formed with a cable ring (33); and

at least a fastener (4) fixed on an object (P) to be locked;

whereby upon direction of said locking bolt (2) and said cable (3) to pass through said fastener (4) of the object (P) and to pass said locking bolt (2) through said cable ring (33) to form a loop of said cable (3) around a fixture (F) to finally lock said locking bolt (2) in said lock body (1) to thereby lock the object (P) to said fixture (F).

2. A cable combination lock according to claim 1, wherein said lock further includes said fastener (4) secured on the fixture (F) to allow said cable (3) operatively passing through said fastener (4) secured on the fixture (F) for fastening said cable (3) on said fixture (F).

3. A cable combination lock according to claim 1, wherein said fastener (4) includes a base (41) fixed on an object or a fixture, and a staple portion (42) formed with the base (41), having a locking aperture formed through said staple portion (42) for passing said locking bolt (2) and said cable (3) through said aperture in said staple portion (42).

4. A cable combination lock according to claim 1, wherein said lock body (1) has a diameter or width larger than that of the cable ring (33) of said cable (3) and larger than that of a locking aperture formed in said fastener (4);

and said locking bolt (2) having a diameter smaller than that of the cable ring (33) and smaller than that of said locking aperture in said fastener (4).

5. A cable combination lock according to claim 1, wherein said lock body (1) includes:

a housing (11), a hollow spindle (12) protruding from a bottom portion (1a) of said housing (11) towards a free end plate (1b) of said housing (11) for rotatably mounting said dials (14) and said sleeves (13) on said spindle (12), a tension spring (15) resiliently urging said sleeves (13) from said bottom portion (1a) towards said free end plate (1b) for resiliently engaging said sleeves (13) with said dials (14), and a thrusting disk (16) held on a retaining plate (17)retained in the free end plate (1b) of said housing (11), with said thrusting disk (16) provided for a combination changing means.

6. A cable combination lock according to claim 5, wherein said housing (11) includes a display window (111) longitudinally formed in said housing (11) for reading a combination of said dials (14);

and a pair of dialing windows (112) disposed on opposite sides of said housing (11) for rotating the dials (14) through said dialing windows (112).

7. A cable combination lock according to claim 5, wherein said spindle (12) is formed with a central hole for inserting therein said locking bolt (2), said locking bolt (2) including a plurality of projections (22) longitudinally formed on said bolt (2);

each said projection (22) operatively engaging with an annular retarding ring (132) annularly formed in each said sleeve (13) for locking said bolt (2) in said lock body (1); and

each said projection (22) operatively engaging with a notch (133) formed through said annular retarding ring (132) of said sleeve (13) for unlocking said bolt (2) from said lock body (1).

8. A cable combination lock according to claim 5, wherein said housing (11) further includes a cover (10) for covering said free end plate (1b) of said housing (11), said locking bolt (2) having an outer portion thereof formed as a handle portion (21) insertable and rotatably in said cover (10) on said housing (11).

9. A cable combination lock according to claim 1, wherein said lock further includes a plurality of fasteners (4), each said fastener (4) fixed on a portable object (P) to be locked to allow said cable (3) operatively respectively passing through said plurality of fasteners (4) respectively fixed on said portable objects for locking said objects by said cable (3).

10. A cable combination lock according to claim 5, wherein said thrusting disk (16) is formed as a combination-changing means, said thrusting disk (16) held between the retaining plate (17) adjacent the free end plate (1b) of the housing (11) and an outermost sleeve (13), with the retaining plate (17) secured on the hollow spindle (12);

said thrusting plate (16) including;

a central opening (161) engaging with the hollow spindle (12), a pair of pushing rods (162) respectively formed on a pair of arcuate sloping portions (163) arcuately formed on opposite ridge portions (164) of the thrusting disk (16), each said pushing rod (162) protruding outwardly through an arcuate guiding slot (172) with two said arcuate guiding slots (172) respectively arcuately formed in opposite side portions of the retaining plate (17), and each said pushing rod (162) protruding outwardly through an outer arcuate guiding slot (1d) with two said outer arcuate guiding slots (1d) respectively arcuately formed in opposite side portions of the free end plate (1b) of the housing (11);

whereby upon rotation of the thrusting disk (16) by biasing the two pushing rods (162), each said sloping portion (163) of the thrusting disk (16) will be tangentially thrusted by an end wall of the arcuate guiding groove (172) of the retaining plate (17), thereby axially driving the sleeves (13) inwardly towards the bottom portion (1a) of the housing (11) for disengaging the sleeves (13) from the dials (14) for free rotation of the dials (14) for resetting a new combination.
