Abstract

A cable lock includes a body and a cable. A latch hole and an elongated hole are respectively defined at two sides of the body. The cable has a latch head secured in the latch hole, and a fixed head extending through the elongated hole. A button is received in the body and located between the latch hole and the elongated hole. A hook is pivotally mounted in the body. The hook has a straight end pushed by a resilient member, and a curved end clasping the cable in the elongated hole. A shaft with a dial is connected with the button. When the dial is turned to a correct sequence, the latch head can be released from the latch hole, and the cable can be freely moved in the elongated hole to release the locked item.

Claims

1. A cable lock comprising:

a body (2) being composed of a first housing and a second housing, the body (2) having a latch hole (21) defined at a first side of the body (2), an elongated hole (22) defined through the body (2) and at a second side of the body (2), a button (4) received in a button hole (23) between the latch hole (21) and the elongated hole (22), a slot (24) defined between the button hole (23) and the latch hole (21), a ball (26) received in the slot and extending in the latch hole (21) in a locked status, the button (4) having a step (42) formed at a side facing the latch hole (21) and in alignment with the slot (24) for receiving the ball (26) in a unlocked status and a cutout (43) defined at another side facing the elongated hole (22), a hook (27) pivotally mounted on a pin (25) formed in the body (2) and adjacent the elongated hole (22), the hook (27) having a straight end (29) abutting the cutout (43) and a curved end (20) extending in the elongated hole (22), a shaft (50) of a dial (5) received in the body (2) and connected with the button (4); and

a cable (3) having a latch head (31) secured in the latch hole (31) by the ball (24) engaged in a ring notch (33) defined on the latch head (31), and a fixed head (32) extending through the elongated hole (22),

whereby, when a sequence of the dial (5) is incorrect, the latch head (31) and the fixed head (32) can not be released from the latch hole (21) and the elongated hole (22) but the fixed head (32) can be pulled to shorten a length of the cable (3) between the latch hole (21) and the elongated hole (22);

when the dial (5) is turned to a correct sequence, the latch head (31) can be released from the latch hole (21), and the cable (3) can be freely moved in the elongated hole (22).

2. The cable lock as claimed in claim 1, wherein the fixed head (32) of the cable (3) has a second latch head (34).

3. The cable lock as claimed in claim 1, wherein the fixed head (32) of the cable (3) has a cord (35).

4. The cable lock as claimed in claim 1, wherein the button (4) has a bottom inclined surface (44), and the shaft (50) has an upper inclined surface (53) formed at a top thereof and engaged with the bottom inclined surface (44), and a resilient member (36) provided thereon.
