Abstract

A watch band includes a strap and a clasp mechanism integrated with an end of the strap. The clasp mechanism includes a concave member defining a channel at the end of the strap and a cover plate. The cover plate is configured to move between (i) a first position in which the cover plate covers the channel, and (ii) a second position in which the cover plate is retracted to leave at least part of the channel uncovered by the cover plate.

First claim

The invention claimed is:

1. A watch band comprising:
a strap; and
a clasp mechanism connected with the strap at a proximal end of the clasp mechanism, the clasp mechanism comprising:
a member defining a channel at a distal end of the clasp mechanism,
a pivot member held in a fixed position with respect to the member defining the channel;
a rocker member configured to rotate about a pivot point defined by the pivot member, the rocker member having a first portion that extends generally away from the pivot member toward the distal end of the clasp mechanism and a second portion that extends generally away from the pivot member toward the proximal end of the clasp mechanism, the rocker member further configured to pivot between:
(i) a first position in which the rocker member covers a portion of the channel sufficient to prevent a spring pin of a watch module from being removed from the channel, and
(ii) a second position in which an end of the rocker member is positioned sufficiently far away from the channel to allow a spring pin of a watch module to be removed from the channel; and

a button affixed to the rocker member, wherein the button is configured to cause the rocker member to pivot from the first position to the second position when pressed.

2. The watch band of claim 1 , wherein the clasp mechanism further comprises a spring configured to bias the rocker member toward the first position and away from the second position.

3. The watch band of claim 2 , wherein the clasp mechanism further comprises a fixed member connected to the member defining the channel; and
wherein the spring comprises a cantilever spring in contact with a portion of the fixed member and a portion of the rocker member.

4. A watch band comprising:
a strap; and
a clasp mechanism connected with the strap at a proximal end of the clasp mechanism, the clasp mechanism comprising:
a member defining a channel at a distal end of the clasp mechanism,
a pivot member held in a fixed position with respect to the member defining the channel; and
a rocker member configured to rotate about a pivot point defined by the pivot member, the rocker member having a first portion that extends generally away from the pivot member toward the distal end of the clasp mechanism and a second portion that extends generally away from the pivot member toward the proximal end of the clasp mechanism, the rocker member further configured to pivot between:
(i) a first position in which the rocker member covers a portion of the channel sufficient to prevent a spring pin of a watch module from being removed from the channel, and
(ii) a second position in which an end of the rocker member is positioned sufficiently far away from the channel to allow a spring pin of a watch module to be removed from the channel;

wherein the clasp mechanism further comprises a spring configured to bias the rocker member toward the first position and away from the second position;
wherein the clasp mechanism further comprises a fixed member connected to the member defining the channel;
wherein the spring comprises a cantilever spring in contact with a portion of the fixed member and a portion of the rocker member; and

wherein at least a portion of the spring at least partially encircles the pivot member.

5. The watch band of claim 2 , wherein the clasp mechanism further comprises:
a housing member connected to the member defining the channel;
wherein a portion of the button extends through the housing member.

6. The watch band of claim 2 , wherein a portion of the button extends through the strap.

7. The watch band of claim 2 , wherein the button is configured to cause the rocker member to pivot, when the button is pressed, in a radial direction that is opposite the radial direction in which the spring biases the rocker member.

8. A watch comprising:
a watch module comprising first and second bars; and
first and second watch bands, each of the first and second watch bands comprising:
a strap; and
a clasp mechanism connected with the strap at a proximal end of the clasp mechanism, the clasp mechanism comprising:
a member defining a channel at a distal end of the clasp mechanism,
a pivot member held in a fixed position with respect to the member defining the channel; and
a rocker member configured to rotate about a pivot point defined by the pivot member, the rocker member having a first portion that extends generally away from the pivot member toward the distal end of the clasp mechanism and a second portion that extends generally away from the pivot member toward the proximal end of the clasp mechanism, the rocker member further configured to pivot between:
(i) a first position in which the rocker member covers a portion of the channel sufficient to prevent the first or second bar of the watch module from being removed from the channel, and
(ii) a second position in which an end of the rocker member is positioned sufficiently far away from the channel to allow the first or second bar of the watch module to be removed from the channel; and

a button affixed to the rocker member, wherein the button is configured to cause the rocker member to pivot from the first position to the second position when pressed.

9. The watch of claim 8 , wherein the clasp mechanism further comprises a spring configured to bias the rocker member toward the first position and away from the second position.

10. The watch of claim 9 , wherein the clasp mechanism further comprises a fixed member connected to the member defining the channel; and
wherein the spring comprises a cantilever spring in contact with a portion of the fixed member and a portion of the rocker member.

11. The watch of claim 10 , wherein at least a portion of the spring at least partially encircles the pivot member.

12. The watch of claim 9 , wherein the clasp mechanism further comprises:
a housing member connected to the member defining the channel;
wherein a portion of the button extends through the housing member.

13. The watch of claim 9 , wherein a portion of the button extends through the strap.

14. The watch of claim 9 , wherein the button is configured to cause the rocker member to pivot, when the button is pressed, in a radial direction that is opposite the radial direction in which the spring biases the rocker member.
