Abstract

A wristband can comfortably secure an electronic device, such as a wristwatch or fitness/health tracking device, to a wrist of a user. The wristband can include a number of magnets that allow the wristband to be magnetically coupled to itself when folded over or when separate band portions are overlapping. The magnets can include a polymer mixed with a magnetic material to provide magnetic properties and flexibility. The magnets can be joined together by a continuous support structure that extends through opposing pairs of the magnets. The support structure can provide substantial and ability as well as tensile strength. The magnets and the support structure can be surrounded by a flexible cover to protect the components within.

First claim

What is claimed is:

1. A wristband for securing a watch to a user, the wristband comprising:
multiple magnets;
a support structure extending between opposing pairs of the magnets;
a connector positioned at an end of the wristband, the connector being configured to connect the wristband to a side of a watch housing, the connector comprising a first part on a first side of the support structure and a second part on a second side of the support structure, the first part and the second part being joined directly to each other with a portion of the support structure secured between the first part and the second part; and
a cover surrounding the magnets, the support structure, and at least a portion of the connector.

2. The wristband of claim 1 , wherein the cover extends about a terminal end of the connector.

3. The wristband of claim 1 , wherein another portion of the connector is exposed by the cover for engagement with the watch housing.

4. The wristband of claim 1 , wherein widths of the magnets are greater than a width of the support structure, such that the opposing pairs of the magnets are connected to each other outside the width of the support structure.

5. The wristband of claim 1 , wherein the magnets are flexible magnets each comprising a mixture of a polymer and particles of a hard magnetic material, and each of the opposing pairs of the magnets are further connected to each other through the support structure, and at least some of the magnets are configured to magnetically couple to each other when the wristband is folded onto itself.

6. The wristband of claim 1 , wherein the support structure comprises woven fibers.

7. The wristband of claim 1 , wherein the support structure comprises holes, wherein each of the holes is positioned between a corresponding pair of the magnets.

8. The wristband of claim 1 , further comprising a free end opposite the connector, wherein the support structure extends continuously from the connector to the free end.

9. A wristband for securing a watch to a user, the wristband comprising:
multiple magnets;
a support structure extending between opposing pairs of the magnets;
a connector configured to connect the wristband to a watch housing;
a locking element coupled to the connector, wherein the support structure is wrapped around opposing sides of the locking element and between the locking element and the connector; and
a cover surrounding the magnets, the support structure, and the locking element.

10. The wristband of claim 9 , wherein the cover extends about a terminal end of the connector.

11. The wristband of claim 9 , wherein a portion of the connector is exposed by the cover for engagement with the watch housing.

12. The wristband of claim 9 , wherein the support structure comprises woven fibers.

13. The wristband of claim 9 , wherein the support structure comprises holes, wherein each of the holes is positioned between a corresponding pair of the magnets.

14. The wristband of claim 9 , further comprising a free end opposite the connector, wherein the support structure extends continuously from the connector to the free end.

15. A wristband for securing a watch to a user, the wristband comprising:
multiple magnets;
a support structure extending between opposing pairs of the magnets;
a connector configured to connect the wristband to a watch housing, the connector defining a first recess;
a locking element coupled to the connector and defining a second recess;
an anchor element coupled to an end of the support structure and disposed within the first recess and the second recess; and
a cover surrounding the magnets, the support structure, the locking element, and the anchor element.

16. The wristband of claim 15 , wherein the cover extends about a terminal end of the connector.

17. The wristband of claim 15 , wherein a portion of the connector is exposed by the cover for engagement with the watch housing.

18. The wristband of claim 15 , wherein the support structure comprises woven fibers.

19. The wristband of claim 15 , wherein the support structure comprises holes, wherein each of the holes is positioned between a corresponding pair of the magnets.

20. The wristband of claim 15 , further comprising a free end opposite the connector, wherein the support structure extends continuously from the connector to the free end.
