Abstract
A convertible lock structure includes a main body including a lock core received therein and a latch rod extending from an end thereof. The main body includes a transverse hole defined therein for receiving an end of a spring-biased control latch. A casing receives the main body and includes an end wall through which the latch rod extends. The casing further includes at least two positioning holes one of which is selected to receive the second end of the control latch. A second end of the control latch is operable by a proper key so as to move between a retracted position inside the main body which allows the main body to move in the casing and an extended position beyond the transverse hole to retain the main body in position.

A convertible lock structure, comprising:
- a main body (1) including a lock core (11) received therein and operable by a proper key, the main body including a transverse hole (14) defined therein, a spring-biased control latch (12) having a first end received in the transverse hole (14) and a second end, the main body further including a latch rod (15) extending from an end thereof,
- a casing (2) for receiving the main body and including an end wall with an opening (25) through which the latch rod (15) extends, the casing further including a first positioning hole (22) and a set of positioning holes comprising two second positioning holes (23a and 23b;
- 24a and 24b), the second end of the control latch (12) being operable by the proper key so as to move between a retracted position inside the main body (1) which allows the main body to move in the casing and an extended position beyond the transverse hole (14) to retain the main body in position, and
- means (26) for returning the main body to initial position thereof,
- wherein one of the first positioning hole (22) and the second positioning holes is selected to receive the second end of the control latch (12), and wherein
- when the first positioning hole (22) is selected, the lock structure is in a locked status when the second end of the control latch (12) is received in the first positioning hole (22), and
- when the second positioning holes is selected, the lock structure is in a locked status when the second end of the control latch (12) is received in one of the second positioning holes (23b;
- 24b), and the lock structure is in an unlocked status when the second end of the control latch (12) is received in the other of the second positioning holes (23a;
- 24a).

- a positioning element (17) having a first end secured to the main body (1) and a second end, and the casing (2) including a first guiding slot (21a), a second guiding slot (21b), and a third guiding slot (21c) defined in a periphery thereof, the second end of the positioning element (17) being received in one of the first guiding slot (21a), the second guiding slot (21b), and the third guiding slot (21c) corresponding to the selection of the first positioning hole (22), the second positioning holes (23a and 23b), and the third positioning holes (24a and 24b) to guide rectilinear movement of the main body (1) in the casing (2), and
- means (26) for returning the main body to initial position thereof,
- wherein one of the first positioning hole, and the second positioning holes, and the third positioning holes is selected to receive the second end of the control latch, and
- wherein when the first positioning hole (22) is selected, the lock structure is in a locked status when the second end of the control latch (12) is received in the first positioning hole (22),
- when the second positioning holes (23a and 23b) is selected, the lock structure is in a locked status when the second end of the control latch (12) is received in one of the second positioning holes (23b), and the lock structure is in an unlocked status when the second end of the control latch (12) is received in the other of the second positioning holes (23a), and
- when the third positioning holes (24a and 24b) is selected, the lock structure is in a locked status when the second end of the control latch (12) is received in one of the third positioning holes (24b), and the lock structure is in an unlocked status when the second end of the control latch (12) is received in the other of the third positioning holes (24a).
