Abstract

In one aspect, the subject matter of the disclosure features a watch band. The 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, the clasp mechanism comprising: a member defining a channel, and
a substantially planar flat cover plate configured to move in a direction parallel to a plane defined by a flat surface of the substantially flat cover plate 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;
wherein the clasp mechanism further comprises:
first and second walls; and
a pair of spring arms attached to respective sides of the cover plate, each of the spring arms biased in a direction against a respective one of the first and second walls.

2. The watch band of claim 1 , wherein the cover plate extends through an aperture in a wall that forms at least a portion of the member that defines the channel when the cover plate is in the first position.

3. The watch band of claim 1 , wherein the pair of spring arms are configured to retain the cover plate in the first position when the cover plate has been moved to the first position, and to retain the cover plate in the second position when the cover plate has been moved to the second position.

4. The watch band of claim 3 , wherein the cover plate and the pair of spring arms are rigidly fixed and substantially coplanar in the plane defined by the flat surface of the substantially flat cover plate.

5. The watch band of claim 1 , wherein the cover plate and the spring arms are substantially coplanar.

6. The watch band of claim 1 , wherein the cover plate and the spring arms are formed of one piece.

7. The watch band of claim 1 , wherein the first and second walls have a first and a second pair of corresponding retaining members;
wherein each of the spring arms comprises a protrusion configured to engage with the retaining members in the respective one of the first and second walls, and
wherein the first pair of retaining members are positioned along the first and second walls to retain the cover plate in the first position when the protrusions of the spring arms are engaged with the first pair of retaining members, and
wherein the second pair of retaining members are positioned along the first and second walls to retain the cover plate in the second position when the protrusions of the spring arms are engaged with the second pair of retaining members.

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, the clasp mechanism comprising:
a member defining a channel, the channel configured to receive one of the first and second bars of the watch module,
a substantially planar cover plate 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, and
a slider mechanism coupled to the cover plate and configured to cause the cover plate to move between the first and the second positions;
wherein the clasp mechanism further comprises:
first and second walls; and
a pair of spring arms attached to respective sides of the cover plate, each of the spring arms biased in a direction against a respective one of the first and second walls.

9. The watch of claim 8 , wherein the cover plate extends through an aperture in a wall that forms at least a portion of the member that defines the channel when the cover plate is in the first position.

10. The watch of claim 8 , wherein the cover plate and the spring arms are substantially coplanar.

11. The watch claim 8 , wherein the cover plate and the spring arms are formed of one piece.

12. The watch of claim 8 , wherein the first and second walls have a first and a second pair of corresponding retaining members;
wherein each of the spring arms comprises a protrusion configured to engage with the retaining members in the respective one of the first and second walls, and
wherein the first pair of retaining members are positioned along the first and second walls to retain the cover plate in the first position when the protrusions of the spring arms are engaged with the first pair of retaining members, and
wherein the second pair of retaining members are positioned along the first and second walls to retain the cover plate in second position when the protrusions of the spring arms are engaged with the second pair of retaining members.
