Abstract

A battery operated device includes a housing, an operating mechanism and an internal battery disposed within the housing, and an access member assembled with the housing and movable between first and second positions. The operating mechanism includes first and second sets of electrical contacts for transmitting power to the operating mechanism, with the internal battery being electrically connectable with the first set of electrical contacts for powering the operating mechanism. The access member is movable between a first position blocking external access to the second set of electrical contacts and connecting the first set of electrical contacts to the internal battery, and a second position permitting external access to the second set of electrical contacts and disconnecting the internal battery from the first set of electrical contacts.

Claims

1. A battery operated device comprising:

a housing;

an operating mechanism disposed within the housing, the operating mechanism including first and second sets of electrical contacts for transmitting power to the operating mechanism;

an internal battery disposed within the housing, the internal battery being electrically connectable with the first set of electrical contacts for powering the operating mechanism; and

an access member assembled with the housing and movable between a first position blocking external access to the second set of electrical contacts and connecting the first set of electrical contacts to the internal battery, and a second position permitting external access to the second set of electrical contacts and disconnecting the internal battery from the first set of electrical contacts.

2. The device of claim 1, wherein the access member retains the internal battery, such that movement of the access member to the second position moves the internal battery out of engagement with the first set of electrical contacts.

3. The device of claim 1, wherein the battery access member is further movable to a third position permitting external access to the internal battery for replacement of the internal battery.

4. The device of claim 3, further comprising a latch member movable between a latching position in which the latch member prevents movement of the access member to the third position, and a releasing position in which the latch member permits movement of the access member from the second position to the third position.

5. The device of claim 4, wherein the operating mechanism is operable to move the latch member from the latching position to the releasing position.

6. The device of claim 5, wherein the operating mechanism includes a user operable interface for entry of an authorized access code to restrict unauthorized operation of the operating mechanism.

7. The device of claim 6, wherein the user operable interface includes an electronic keypad.

8. The device of claim 4, wherein the operating mechanism comprises a locking mechanism including an access restricting structure movable between locked and unlocked positions, wherein the latch member is secured in the latching position when the access restricting structure is in the locked position.

9. The device of claim 8, wherein the access restricting structure comprises a shackle, and further wherein a portion of the shackle blocks movement of the latch member to the releasing position when the access restricting structure is in the locked position.

10. The device of claim 1, wherein the second set of electrical contacts is configured for electrical connection with an external battery when the access member is in the second position, the external battery being substantially identical to the internal battery.

11. A battery operated device comprising:

a housing;

an operating mechanism disposed within the housing, the operating mechanism including first and second sets of electrical contacts for transmitting power to the operating mechanism;

an internal battery disposed within the housing, the internal battery being electrically connectable with the first set of electrical contacts for powering the operating mechanism; and

an access member assembled with the housing and movable between a first position blocking external access to the internal battery and blocking external access to the second set of electrical contacts, a second position blocking external access to the internal battery and permitting external access to the second set of electrical contacts, and a third position permitting external access to the internal battery for replacement of the internal battery.

12. The device of claim 11, further comprising a latch member disposed within the housing and movable between a latching position in which the latch member prevents movement of the access member to the third position, and a releasing position in which the latch member permits movement of the access member to the third position.

13. The device of claim 12, wherein the operating mechanism comprises a locking mechanism including an access restricting structure movable between locked and unlocked positions, wherein the latch member is secured in the latching position when the access restricting structure is in the locked position.

14. The device of claim 13, wherein the access restricting structure comprises a shackle, and further wherein a portion of the shackle blocks movement of the latch member to the releasing position when the access restricting structure is in the locked position.

15. The device of claim 12, wherein the operating mechanism is operable to move the latch member from the latching position to the releasing position.

16. The device of claim 11, wherein the operating mechanism includes a user operable interface for entry of an authorized access code to restrict unauthorized operation of the operating mechanism.

17. The device of claim 16, wherein the user operable interface includes an electronic keypad.

18. An electronic padlock comprising:

a lock body;

a shackle assembled with the lock body and movable between locked and unlocked positions;

an electronic lock interface assembled with the lock body;

an electromechanical locking mechanism disposed within the body and operable to permit movement of the shackle from the locked position to the unlocked position in response to proper user manipulation of the electronic lock interface, the electromechanical locking mechanism including first and second sets of electrical contacts for transmitting power to the operating mechanism;

an internal battery disposed within the lock body and electrically connectable with the electromechanical locking mechanism by the first set of electrical contacts; and

an access member assembled with the lock body and movable between a first position blocking external access to the internal battery and blocking external access to the second set of electrical contacts, a second position blocking external access to the internal battery and permitting external access to the second set of electrical contacts, and a third position permitting external access to the internal battery for replacement of the internal battery.

19. The padlock of claim 18, wherein movement of the access member to the second position disconnects the internal battery from the first set of electrical contacts, thereby preventing simultaneous power supply to the operating mechanism through both the first and second sets of electrical contacts.

20. The padlock of claim 18, wherein the access member retains the internal battery, such that movement of the access member to the second position moves the internal battery out of engagement with the first set of electrical contacts.

21. The padlock of claim 18, further comprising a latch member disposed within the lock body and movable between a latching position in which the latch member prevents movement of the access member to the third position, and a releasing position in which the latch member permits movement of the access member to the third position.

22. The padlock of claim 21, wherein the latch member is secured in the latching position when the shackle is in the locked position.

23. The padlock of claim 21, wherein a portion of the shackle blocks movement of the latch member to the releasing position when the shackle is in the locked position.
