Abstract

A lock contains: an attachment member and a fixing device. The attachment member includes a base, a first movable connection part and a second movable connection part which are rotatably connected on the base can expandable outward and retractable inward. The first movable connection part has a first extension, a first post opposite to the first extension, and a first tab. The second movable connection part has a second extension, a second post opposite to the second extension, and a second tab. The fixing device includes a case and a locking mechanism. The case is configured to fit with the base and has a retaining groove. The locking mechanism is arranged in the case and includes a movable rod configured to separate the first movable connection part from the second movable connection part.

First claim

What is claimed is:

1. A lock configured to be coupled to a locking orifice of a portable device, the lock comprising:
an attachment member configured to be coupled to the locking orifice of the portable device, the attachment member including
a base, and
a first movable connection part and a second movable connection part which are coupled to the base, wherein the first movable connection part has a first extension configured to be coupled to the locking orifice, a first post opposite to the first extension, and a first tab formed on an outer wall of the first post and disposed outside the base, wherein the second movable connection part has a second extension configured to be coupled to the locking orifice, a second post opposite to the second extension, and a second tab formed on an outer wall of the second post and disposed outside the base; and

a fixing device including:
a case configured to be coupled to the base and having a retaining groove formed in the case; and
a locking mechanism arranged in the case and including a movable rod configured to move between the first post of the first movable connection part and the second post of the second movable connection part when the first post and the second post move away from each other so that the first tab of the first post and the second tab of the second post are retained in the retaining groove, the first post of the first movable connection part and the second post of the second movable connection part being movable toward each other so that the first tab of the first post and the second tab of the second post are removed from the retaining groove.

2. The lock as claimed in claim 1 , wherein the base is a circular column.

3. The lock as claimed in claim 1 , wherein the first post of the first movable connection part has a first recess formed on an inner wall thereof, and the second post of the second movable connection part has a second recess formed on an inner wall thereof.

4. The lock as claimed in claim 3 , wherein the first post further has a first tilted guide face arranged on an edge thereof, and the second post further has a second tilted guide face arranged on an edge thereof.

5. The lock as claimed in claim 1 , wherein the locking mechanism is a key locking mechanism.

6. The lock as claimed in claim 1 , wherein the locking mechanism is a combination locking mechanism.

7. The lock as claimed in claim 1 , wherein the case is in connection with a flexible chain.

8. The lock as claimed in claim 1 , wherein the first extension and the second extension move away from each other when the first post and the second post move away from each other and the first extension and the second extension move toward each other when the first post and the second post move toward each other.

9. The lock as claimed in claim 3 , wherein the movable rod is configured to move in the first recess and the second recess when the first post and the second post move away from each other.

10. The lock of claim 4 , wherein the movable rod is further configured to move between the first post and the second post along the first tilted guide face and the second tilted guide face.

11. The lock as claimed in claim 1 , wherein the case is further formed with a protrusion on an inner wall thereof configured to abut the first post and the second post during coupling of the case to the base to move the first post and the second post toward each other.

12. The lock as claimed in claim 1 , wherein the case is further formed with a protrusion on an inner wall thereof configured to be disposed between the base and the first tab when the case is coupled to the base.

13. The lock as claimed in claim 1 , wherein the case surrounds the base when the case is coupled to the base.

14. An attachment member configured to be coupled to a locking orifice of a portable device, the attachment member comprising:
a base; and
a first movable connection part and a second movable connection part which are coupled to the base, wherein the first movable connection part has a first extension configured to be coupled to the locking orifice, a first post opposite to the first extension, and a first tab formed on an outer wall of the first post and disposed outside the base, wherein the second movable connection part has a second extension configured to be coupled to the locking orifice, a second post opposite to the second extension, and a second tab formed on an outer wall of the second post and disposed outside the base.

15. The attachment member as claimed in claim 14 , wherein the base is a circular column.

16. The attachment member as claimed in claim 14 , wherein the first post further has a first tilted guide face arranged on an edge thereof, and the second post further has a second tilted guide face arranged on an edge thereof.

17. The attachment member as claimed in claim 14 , wherein each of the first and second tabs has a first sidewall facing the base and an inclined second sidewall opposite the first sidewall.

18. The attachment member as claimed in claim 14 , wherein the first extension and the second extension move away from each other when the first post and the second post move away from each other and the first extension and the second extension move toward each other when the first post and the second post move toward each other.

19. The attachment member of claim 14 , wherein the first and second posts abut a sidewall of the base when the first and second posts move away from each other.

20. The attachment member of claim 14 , wherein the first and second posts move away from a sidewall of the base when the first and second posts move toward each other.
