Abstract

A band is disclosed which attaches to a portable electronic device. The band includes a flexible length of material which forms a loop into which a pin is inserted. In one embodiment, the loop has an insert with a protrusion therein. The protrusion frictionally contacts the pin. In another embodiment the pin includes an elastomeric surface. The elastomeric surface may include O-rings between two pin portions such that the amount of the elastomeric surface extending beyond the pin may be adjusted. In another embodiment, the elastomeric surface includes a sleeve on the pin.

Claims

1. An attachment mechanism for a watch, the attachment mechanism comprising:

a securement mechanism removably attachable to a body of the watch;

a pin attached to the securement mechanism;

a band forming a loop through which the pin passes; and

a frictional insert within the loop, and engaging the pin and the band;

wherein;

the frictional insert is shaped to occupy a space defined by the pin and the band;

the frictional insert tapers along its length from a first end abutting the pin to a second, smaller end that is opposite the first end; and

the frictional insert is configured to increase friction between the pin and the band, thereby reducing motion of the band with respect to the pin.

2. A watch comprising:

a watch body; and

the attachment mechanism of claim 1, wherein the securement mechanism is removably attached to the watch body.

3. The attachment mechanism of claim 1, wherein the frictional insert is formed on the band.

4. The attachment mechanism of claim 3, wherein the frictional insert is made from polyurethane.

5. The attachment mechanism of claim 1, wherein the frictional insert comprises:

an insert body having a first dimension and abutting the band; and

a neck having a second dimension and abutting the pin;

wherein

the first dimension is less than the second dimension.

6. The attachment mechanism of claim 5, wherein the neck is a rib formed unitarily with the insert body.

7. The attachment mechanism of claim 5, wherein the insert body is formed from a separate material from the neck.

8. The attachment mechanism of claim 1, wherein the frictional insert is an elastic collar.

9. The attachment mechanism of claim 8, wherein:

the elastic collar is received within a seam of the pin; and

a surface of the elastic collar is offset by an offset distance from a surface of the pin.

10. The attachment mechanism of claim 9, wherein the offset distance is controlled by compressing the elastic collar.

11. A method for controlling motion of a band with respect to a securement mechanism of an electronic device, comprising:

adjusting an offset distance between a securement mechanism and the band;

in response to adjusting the offset distance, increasing a friction between an elastic element and the band; and

in response to increasing the friction between the elastic element and the band, maintaining a spatial relationship between the securement mechanism and the band.

12. The method of claim 11, wherein the elastic element encircles a pin of the securement mechanism.

13. The method of claim 11, wherein the elastic element is received in a seam of the securement mechanism.

14. The method of claim 13, wherein of adjusting the offset distance comprises moving a first pin section relative to a second pin section, thereby changing a compression of the elastic element.

15. The method of claim 14, wherein the offset distance corresponds to a distance between an outer surface of the elastic element and an outer surface of the pin.

16. The method of claim 15, wherein maintaining a spatial relationship between the pin and the band comprises maintaining a translational and a rotational alignment between the pin and the band.

17. The method of claim 15, further comprising maintaining translational and rotational alignment of the electronic device with respect to the band.

18. An attachment mechanism for a watch, the attachment mechanism comprising:

a securement mechanism comprising;

a body; and

a pin affixed to the body;

an elastic collar about the pin;

a flexible strap; and

a frictional device;

wherein;

the flexible strap defines a gap;

the frictional device is positioned within the gap;

the frictional device engages the flexible strap; and

the frictional device frictionally engages the elastic collar.

19. The attachment mechanism of claim 18, wherein the frictional device affixed to the flexible strap.

20. A watch comprising:

a watch body; and

the attachment mechanism of claim 18, wherein the securement mechanism is removably attached to the watch body.
