Abstract

A locking device (10) for securing a portable object to an immovable object (18) by a cable (16). The locking device comprises at-least two simultaneously rotatable T-shaped heads (24a; 24b), adapted to be inserted through at-least two complementary slots (22a; 22b) formed in a side wall (20) of the portable object and rotated by about 900 in the inserted position thus preventing the separation of the device from said side-wall. The slots extend in parallel or non-parallel directions.

Claims

1. An anti-theft arrangement for securing a portable object to an immovable object by a cable fastened at one end thereof to a key-operated locking device adapted to become selectively locked against, and unlocked from, a side-wall of said portable object, the arrangement comprising:

A. A first pair of slots formed in said side-wall;

B. a lock body having a flat wall formed with a second pair of slots configured to overlap the said first pair of slots;

C. said locking device being accommodated within said lock, body, the device comprising;

a pair of elements having each a stem and a T-shaped head, each head projecting through one of said second pair of slots by a distance exceeding the width of said side-wall, said stems extending parallel to each other;

a rotor rotatable by a key into a first, locked position and a second, unlocked position;

means for coupling the said stems to the rotor for rotating both stems in unison; and

D. means for securing one end of said cable to the said lock body.

2. The arrangement as claimed in claim 1, wherein the said rotor forms a part of a push-button type lock installed at a side of said lock body opposite the said flat wall thereof.

3. The arrangement as claimed in claim 2, wherein each of the said stems extend from one of a pair of meshing gear-wheels, at least one of the gear-wheels being coupled to said rotor.

4. The arrangement as claimed in claim 3, wherein the said T-shaped heads extend in crossing directions,

5. The arrangement as claimed in claim 3, wherein the said T-shaped heads extend in parallel directions.

6. The arrangement as claimed in claim 2, wherein one of the gear-wheels is coupled to the said rotor and the other is freely rotatable.

7. The arrangement as claimed in claim 6, wherein said one gear-wheel is coupled to the rotor by a rotatably supported cylindrical member axially connected to the gear-wheel.

8. The arrangement of claim 1, wherein each of said pair of elements comprises a gear-wheel mounted to said stem at the side opposite to the T-shaped head, meshing with each other and carrying driving pins, the driving pins being coupled to a first disc drivingly coupled to said rotor.

9. The arrangement as claimed in claim 8, wherein said driving pins are eccentrically mounted to a surface of their respective gear-wheels.

10. The arrangement as claimed in claim 9, wherein the gear-wheels are rotatively supported by a second disc.

11. The arrangement as claimed in claim 10, wherein the gear-wheels are seated within shallow circular cavities formed in a surface of said second disc.

12. A locking device for securing a portable object to an immovable object by a cable, the locking device comprising at-least two simultaneously rotatable T-shaped heads, adapted to be inserted through at-least two complementary slots formed in a side wall of the portable object and rotated by about 90°

in the inserted position thus preventing the separation of the device from said side-wall.

13. The locking device as claimed in claim 12, wherein the said slots extend in parallel directions.

14. The arrangement as claimed in claim 12, wherein the said slots extend in non-parallel directions.

15. The arrangement as claimed in claim 12, wherein the T-shaped heads are each extended by a stem with meshing gear-wheels configured to impart simultaneous rotational movement to the T-shaped heads.

16. The arrangement as claimed in claim 15, wherein the said rotational movement is generated by a key-operated locking mechanism.

17. The arrangement as claimed in claim 16, wherein the key-operated locking mechanism is drivingly coupled to at-least one of said gear-wheels.
