Abstract

A sleeve for use in an assembly for coupling a wristworn device to a first end of a strap. The sleeve has a first end dimensioned to be received in the recess in the inner face of the first lug of a wristworn device, an inner cavity dimensioned to receive therein the first end of a conventional spring bar, and a retractor coupled to the sleeve for urging the first end of the spring bar towards the second end of the spring bar. The second end of the spring bar is coupled to the second lug, the spring bar is coupled to the strap, the first end of the spring bar is positioned in the inner cavity of the sleeve and the first end of the sleeve is coupled to the first lug. A removable retractor for use with a spring bar, which allows for the use of a plurality of spring bars and therefore, lends itself to widespread use and retrofitting of an assembly that couples a strap to a wristworn device, is also provided.

Claims

1-8. -8. (canceled)

9. An assembly for coupling a wristworn device to a first end of a strap, wherein the wristworn device comprises a first lug and a second lug spaced from the first lug, wherein the first lug includes a recess in an inner face thereof and the second lug includes a recess in an inner face thereof, and wherein the assembly is coupleable to the first end of the strap, wherein the assembly comprises:

a spring bar comprising a first end and a second end, wherein the first end is dimensioned to be received in the recess in the inner face of the first lug, and the second end is dimensioned to be received in the recess in the inner face of the second lug, and a biasing member for permitting the first end of the spring bar to be biased towards and away from the second end of the spring bar; and

a retractor, the retractor being removably coupled to the first end of the spring bar, the retractor being engagable for urging the first end of the spring bar towards the second end of the spring bar;

whereby when the second end of the spring bar is positioned in the recess in the inner face of the second lug and the first end of the spring bar is positioned in the recess in the inner face of the first lug, urging the first end of the spring bar toward the second end of the spring bar by engaging the retractor causes the first end of the spring bar out of the recess of the inner face of the first lug.

10. The assembly as claimed in claim 9, wherein at least the first end of the spring bar comprises at least a first and second rip, wherein the retractor is removably coupled between the first and second rip.

11. The assembly as claimed in claim 9, wherein the retractor is ring-shaped.

12. The assembly as claimed in claim 9, wherein the retractor is half ring-shaped.

13. The assembly as claimed in claim 9, wherein at least the first end of the spring bar comprises at least a first and second rip, wherein the retractor is in the shape of a full ring or half ring, and wherein the retractor is removably positioned between the first and second rip.
