Patent ID: 8001658

Claim:
A clasp for a band, said clasp comprising: a succession of at least two long arms that are articulated with each other, a locking device for keeping the long arms in a position folded against each other in a locked position of the locking device, transverse connecting members for connecting two of the long arms forming respective ends of the succession of the long arms to respective free ends of a band, and a mechanism for adjusting a longitudinal position of the transverse connecting member connecting one of the free ends of the band to a first one of the two long arms forming the ends of the succession of the long arms, wherein said mechanism comprises (i) a sliding device comprising: two tracks defining two corresponding paths extending laterally in two planes parallel to the longitudinal axis of the first long arm, two stops defining an active length of the tracks, sliding elements integral with respective lateral ends of the transverse connecting member, wherein the sliding elements engage with the respective tracks so as to allow the transverse connecting member to move translationally along the tracks but not rotationally with respect to the tracks, and (ii) a positioning device comprising: a first part including a plurality of longitudinal positioning elements extending along the first long arm, for a length approximately equal to the distance between the two stops, and a second part including an immobilizing element integral with said transverse connecting member, shaped to engage when desired with said plurality of longitudinal positioning elements, wherein a transversally oriented portion of each respective track and a transversally oriented portion of the sliding element engaged with the respective track comprise complementary adjacent surfaces extending in the direction of translational movement defined by the tracks, so as to prevent the transverse connecting member from moving transversally with respect to the tracks, so that said transverse connecting member is allowed to move translationally only along the tracks when said plurality of positioning elements and said immobilizing element of the positioning device are not engaged with each other, and said transverse connecting member is immobilized with respect to said tracks when said plurality of positioning elements and said immobilizing element are engaged with each other.
