Consistently-tight watch band
First Claim
1. A watch band, comprising:
- a first end for connecting to a watch body;
a second end for connecting to the watch body,repetitive compliant mechanisms along the watch band between the first end and the second end, each of the repetitive compliant mechanisms being movable between a non-extended position and an extended position, each of the repetitive compliant mechanisms comprising two opposing spring segments connected at a pivot point, wherein the opposing spring segments form an angle less than 180 degrees in the non-extended position, wherein the opposing spring segments form an angle greater than 180 degrees in the extended position.

Abstract
A watch band is disclosed. The watch band maintains a substantially constant tension throughout changes in its length while worn by a user. Such changes in length may occur automatically to accommodate changes in the size and circumference of a user'"'"'s wrist as they move their wrist normally. By maintaining a constant tension, the watch band also maintains a constant force on the user'"'"'s wrist, and causes a watch body attached to the watch band to also maintain a constant force on the user'"'"'s wrist. This can increase a user'"'"'s comfort, since the watch will not get tighter or constrict their wrist as they straighten and bend their wrist. It can also help optimize operation of any sensors in the watch band or watch body that benefit from being held against the user'"'"'s wrist with a constant force, such as some physiological sensors.

1. A watch band, comprising:
-
a first end for connecting to a watch body; a second end for connecting to the watch body, repetitive compliant mechanisms along the watch band between the first end and the second end, each of the repetitive compliant mechanisms being movable between a non-extended position and an extended position, each of the repetitive compliant mechanisms comprising two opposing spring segments connected at a pivot point, wherein the opposing spring segments form an angle less than 180 degrees in the non-extended position, wherein the opposing spring segments form an angle greater than 180 degrees in the extended position. - View Dependent Claims (2, 3, 4, 5)

6. A watch band, comprising:
-
repetitive compliant mechanisms, wherein each repetitive compliant mechanism is movable between a non-extended position and an extended position, and wherein the repetitive compliant mechanisms sequentially move between the non-extended position and the extended position as a length of the watch band is changed, wherein each repetitive compliant mechanism is formed by at least one discontinuity through the watch band, wherein within each repetitive compliant mechanism the at least one discontinuity forms two opposing spring segments connected at a pivot point, and wherein the two opposing spring segments pivot relative to each other and compress against each other as a tension is applied at the pivot point to move the repetitive compliant mechanism from the non-extended position to the extended position, wherein the opposing spring segments of each repetitive compliant mechanism are connected to each other at an angle less than 180 degrees when in the non-extended position, wherein the angle increases as the two opposing spring segments pivot relative to each other and compress against each other as the tension is applied, and wherein as the angle increases vast 180 degrees, the opposing spring segments extend. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A watch band, comprising:
-
a first end for connecting to a watch body; a second end for connecting to the watch body, repetitive compliant mechanisms along the watch band between the first end and the second end, each of the repetitive compliant mechanisms comprising two opposing spring segments each comprising; a first end connected to one of a pair of ground joints; and a second end connected to a pivot point that joins together the two opposing spring segments; wherein each of the repetitive compliant mechanisms is movable between a non-extended position and an extended position, wherein the pivot point is on a first side of the pair of ground joints in the non-extended position, wherein the pivot point is on a second side of the pair of ground joints in the extended position, the first side being opposite the second side. - View Dependent Claims (15, 16, 17, 18)
