Abstract

A watch for providing a digital time display comprises a movement mechanism disposed in a case that includes a number of continuous belts. The belts each have a numerical indicia consistent with hours, minutes and optionally second. The belts mounted over opposed drums, and the drums are rotated through gear engagement motors to move the belts. The arrangement of belts and drums are mounted on a frame separate from the case. The motors are operated to move the belts to cause the numerical indicia of the combined belts to register with one or more windows visible through a transparent cover to provide a time display. The belts may be oriented to overlap one another. The watch includes a microcontroller for controlling the operation of the motors, an optical sensor to determining the position of the belts, and a wirelessly rechargeable battery pack for powering the motors.

Claims

1. A timepiece comprising:

a casing;

a number of belts disposed within the casing, wherein the belts include indicia on an outer surface, and wherein at least one of the belts is arranged to overlap another belt;

means disposed within the case for moving the belts; and

a cover disposed over a front portion of the casing, wherein the indicia on the belts is visible through at least a portion of the cover;

means for providing a time display from the indicia on the belts, the means being disposed adjacent the cover.

2. The timepiece as recited in claim 1 wherein means for providing a time display comprises a window that is positioned to provide an hour display from the indicia on one of the belts.

3. The timepiece as recited in claim 2 wherein the means for providing a time display further comprises a window that is positioned to provide a minute display from the indicia on one or more of the belts.

4. The timepiece as recited in claim 1 wherein the means for providing a time display is interposed between an outside surface of a respective belt and the cover.

5. The timepiece as recited in claim 1 wherein the indicia on one of the belts provides an hour time display.

6. The timepiece as recited in claim 1 wherein the indicia on two of the belts when combined operates to provide a minute time display.

7. The timepiece as recited in claim 1 wherein one of the belts is oriented within the case at an angle relative to another of the belts.

8. The timepiece as recited in claim 1 wherein the belts are of a continuous construction, and wherein the timepiece further comprises means for engaging the belts for movement by the means for moving.

9. The timepiece as recited in claim 1 wherein the means for moving comprises a motor.

10. A time keeping device comprising:

a casing;

a number of belts disposed within the casing and having a printed numerals disposed along an outside surface, wherein one of the belts is oriented within the casing to overlap another one of the belts;

means for moving the belts in a time coordinated manner, the means being disposed within the casing;

one or more windows disposed within the device positioned to provide a time display from the printed numerals on the belts when viewed through the one or more windows.

11. The device as recited in claim 10 wherein one of the belts comprise printed numerals that operate to provide an hour time display when viewed through the one or more windows.

12. The device as recited in claim 10 comprising two belts having printed numbers that operate when combined to provide a minute display when viewed through the one or more windows.

13. The device as recited in claim 10 further comprising means connected with the casing to facilitate wearing the device on a user'"'"'s wrist.

14. The device as recited in claim 10 wherein the means for moving is a motor, and wherein the device comprises more than one motor that is operatively coupled to a respective belt.

15. The device as recited in claim 10 wherein the belts are of a continuous construction.

16. A method for providing a time display from a device comprising the steps of:

moving a number of belts disposed within a casing of the device, wherein the belts include numerals disposed along an outside surface, and wherein two of the belts are oriented within the casing to overlap one another, and wherein the step of moving takes place in a time coordinated manner; and

registering the numerals on the belts with one or more windows of the device to provide a time display of hours and minutes viewed from outside of the device.

17. The method as recited in claim 16 wherein the device comprises means connected with the case to facilitate wearing the device on a user'"'"'s wrist.

18. The method as recited in claim 16 wherein the belts are of a continuous construction, and wherein the device include a motor that operates to move a respective belt in a rotational manner.

19. The method as recited in claim 16 wherein the numerals on one of the belts provides an hour time display when registering with one or more of the windows.

20. The method as recited in claim 16 wherein the numerals provides a minute time display when registering with one or more of the windows.
