A buckle for a pair of band sections connected to an object at a pair of opposite positions for wearing the object on a user's body includes a frame connected to one band section, a length adjustment chain connected to the other band, a chain folding-back shaft for folding back the chain, and a folding-back shaft position adjuster for moving the position of the folding-back shaft adjustably. When the position of the shaft is changed in the length direction of the frame, the position where the chain is folded back by the shaft changes and a distance between both the band sections is adjusted.

A buckle mechanism (1), for releasably and adjustably connecting an attachment member (3) to a tongue member (5), comprises a fixed buckle member (2) connected to or adapted for being connected to the attachment member (3). A movable element (4) that is adapted to be connected to the tongue member (5) is slidably mounted inside the fixed buckle member (2) between a first stable position and a second stable position for varying a distance along a pulling direction between said tongue member (5) and said attachment member (3). This mechanism further comprises a manually-operable lever system (6, 6′) for moving the movable element (4) between its first and second stable position.

A invention relates to a watch strap, having a strap end link 1 which is connected to a further component such that it can be pivoted about an axis transverse to the longitudinal extent of the wrist strap and which can be adjusted relative to the further component in the direction of the longitudinal extent of the wrist strap. The strap end link 1 is articulated on a pivot element 3 such that it can be pivoted about an adjustment axis 2 which extends, approximately in the strap plane, transversely to the longitudinal extent of the wrist strap, the pivot element being connected to the further component such that it can be pivoted through approximately 180° about a pivot axis 4 which is parallel to the adjustment axis 2. In this case, the pivot element 3 can be arrested in its pivot end positions. The adjustment axis 2 and pivot axis 4 are arranged one behind the other in this case approximately along the longitudinal extent of the wrist strap.

The extensible bracelet clasp is of the unfolding buckle type. It includes a first assembly (1) comprising a cap (3) and a push-piece (5) adapted to slide on a second assembly (2) in order to adjust the length of the clasp. Such second assembly (2) comprises an arrangement (15) on which the push-piece (5) can act in order to open the clasp, such arrangement (15) and such push-piece being respectively provided with indexing means (16) and positioning means (17) in order to permit adjustment in length of the clasp and to retain the memory of such adjustment when the clasp is opened. The clasp can be used for a watch bracelet.
摘要:
An adjustable buckle for a band in which a plate is telescopically held within an open end housing containing a ratchet and a second plate is hinged to and foldable over the first plate and releasably securable thereto in folded over position and is provided with a hook at its end for engagement of the other end of the band. A pawl is secured to the first plate by a resilient arm which normally maintains the pawl out of engagement with the ratchet. The second plates is provided with a projection which engages the pawl to press it into engagement with the ratchet when the second plate is folded against the first plate.
