Abstract

An example ring lock generally includes a housing, a shackle, a lock mechanism, and an indicator. The shackle is mounted to the housing for movement between a first position and a second position. The lock mechanism is configured to selectively retain the shackle in at least one of the first position or the second position. The indicator is operable to selectively display an indicium related to an open/closed state of the ring lock. The indicator is configured to display the indicium when the shackle is in the first position, and is configured to not display the indicium when the shackle is in the second position.

First claim

What is claimed is:

1. A ring lock, comprising:
a housing;
a shackle mounted to the housing for movement between a first position and a second position;
a lock mechanism configured to selectively retain the shackle in at least one of the first position or the second position;
an actuator coupled with the shackle and operable to move the shackle between the first position and the second position when the lock mechanism is unlocked; and
an indicator operable to selectively display an indicium related to an open/closed condition of the ring lock, wherein the indicator is configured to display the indicium when the shackle is in the first position, and wherein the indicator is configured to not display the indicium when the shackle is in the second position;
wherein the indicium is not obscured by the actuator when the shackle is in the first position; and
wherein the indicium is obscured by the actuator when the shackle is in the second position.

2. The ring lock of claim 1 , wherein the housing defines an arcuate path along which the actuator is operable to travel; and
wherein the indicator is positioned at one end of the arcuate path.

3. The ring lock of claim 1 , wherein a visible portion of the housing comprises a first color; and
wherein the indicium comprises a second color different from the first color.

4. The ring lock of claim 1 , wherein the first position is a closed position and the second position is an open position.

5. The ring lock of claim 1 , wherein the lock mechanism is operable to selectively retain the shackle in at least the second position.

6. The ring lock of claim 1 , wherein the housing defines a guide path along which an actuator travels during movement of the shackle between the first position and the second position; and
wherein the indicium is positioned at one end of the guide path.

7. A wheeled transportation device comprising the ring lock of claim 1 , the wheeled transportation device further comprising a frame and a wheel rotatably mounted to the frame;
wherein the housing is secured to the frame; and
wherein, with the shackle in a closed position, a portion of the wheel is enclosed within the ring lock.

8. A portable lock apparatus, comprising:
a housing;
a shackle movable relative to the housing between a first position and a second position, wherein one of the first position or the second position is a closed position, and wherein the other of the first position or the second position is an open position;
an actuator operable to move the shackle between the open position and the closed position; and
an indicator configured to selectively display an indicium;
wherein the actuator exposes the indicium when the shackle is in the first position; and
wherein the actuator obscures the indicium when the shackle is in the second position.

9. The portable lock apparatus of claim 8 , wherein the housing defines a guide path along which the actuator travels to move the shackle between the first position and the second position; and
wherein the indicator is positioned at one end of the guide path.

10. The portable lock apparatus of claim 9 , wherein the guide path is arcuate.

11. The portable lock apparatus of claim 8 , wherein the first position is the closed position and the second position is the open position.

12. The portable lock apparatus of claim 8 , further comprising a lock mechanism operable to selectively retain the shackle in the closed position.

13. The portable lock apparatus of claim 8 , wherein at least a portion of the housing is a first color; and
wherein the indicium comprises a second color different from the first color.

14. The portable lock apparatus of claim 8 , wherein the shackle is movably coupled to the housing.

15. A method of operating a ring lock including a housing, a shackle movably mounted to the housing, an actuator coupled with the shackle, and an indicium, the method comprising:
in response to movement of the actuator between a first actuator position and a second actuator position, moving the shackle between a first shackle position and a second shackle position, wherein one of the first shackle position or the second shackle position is a closed position, and wherein the other of the first shackle position or the second shackle position is an open position; and
selectively displaying the indicium, comprising:
exposing the indicium when the actuator is in the first actuator position, thereby displaying the indicium when the shackle is in the first shackle position; and
covering the indicium with the actuator when the actuator is in the second actuator position, thereby obscuring the indicium when the shackle is in the second shackle position.

16. The method of claim 15 , wherein the indicium relates to a closed condition of the ring lock;
wherein the first shackle position is the closed position; and
wherein the second shackle position is the open position.

17. The method of claim 15 , wherein displaying the indicium comprises exposing the indicium; and
wherein not displaying the indicium comprises obscuring the indicium.

18. The method of claim 15 , wherein at least a portion of the housing is a first color; and
wherein the indicium comprises a second color different from the first color.
