Definitions

  • the invention relates to a fastening device for a bracelet on the housing of a wristwatch, with a crosspiece which can be fastened transversely to the longitudinal direction of the band in a connector of the housing and can be inserted into a recess at one end of the bracelet.
  • the crossbars as spring bars, the ends of which are telescopic and can be compressed against a spring force. As a result, the length of the crosspieces can be reduced and the crosspieces can be removed from the recesses. Due to the small size of the crossbars, the assembly and disassembly of the bracelet is difficult. Force applied to the crossbars by the bracelet can easily lead to unintentional loosening of the crossbars.
  • a fastening device for a bracelet on the housing of a wristwatch in which a crosspiece is fastened centrally to a connector of the housing by means of a retaining screw which extends approximately axially to the pointer axis of the watch.
  • the bracelet encircles the areas of the crossbar extending to the right and left of the retaining screw. The tensile forces of the bracelet are transmitted from the ends of the bracelet to the crossbar, which in turn supports these forces via the retaining screw on the connector of the housing.
  • the object of the invention is therefore to provide a fastening device of the type mentioned, which is easy to assemble and disassemble and secured against automatic loosening.
  • the crossbar for transmitting the forces acting on the crossbar from the bracelet, the crossbar can be inserted into a recess coaxial with the recess of the bracelet, the connecting piece of the housing absorbing the forces of the bracelet, the connecting piece being approximately at right angles to the recess of the Connection piece intersecting opening can be used in which a locking piece which secures the transverse web against axial displacement and cannot be loaded by the forces acting on the crossbar of the bracelet, which protrudes through a locking recess formed on the transverse web transversely to the longitudinal direction of the band and within the connecting piece is non-positive, positive or non-positive and positive is connectable to the crossbar or to the connector.
  • the locking piece can have an arm which can be inserted approximately at right angles into the locking recess of the crossbar, the locking recess being a circular groove on the lateral surface of the crossbar in a simple embodiment.
  • the locking piece has two fork-like arms that can be inserted around the crossbar into the ring only, a symmetrical securing of the crossbar is achieved.
  • the arm can be a spring arm which can be snapped into the locking recess.
  • This securing can be further strengthened by the fact that the spring arm on its side facing the crosspiece has a depression approximately corresponding to the contour of the crosspiece in the area of the locking recess, which recess can be snapped onto the crosspiece.
  • the opening can preferably be closed by a closure part of the locking piece on the side facing an observer of the watch.
  • the closure part can also be provided with a decorative ornament. This means that no special devices are required in order to be able to attach the decorative ornaments to the watch.
  • the locking piece is provided on its side facing an observer with a gripping piece, wherein the gripping piece can be formed in a simple manner by an extension projecting toward the observer.
  • a radially circumferential groove on the lateral surface of the attachment enables easy grasping by hand or with a tool, so that the holding forces acting on the locking piece can be easily overcome for disassembly. This also prevents scratching or damaging the watch when the bracelet is disassembled.
  • the locking piece can consist of a sleeve of the same outer contour as the inner contour of the opening, which can be engaged with an area of its wall in the locking recess.
  • the sleeve has a slot which runs transversely to the side facing away from the observer and whose width corresponds approximately to the width of the crosspiece in the region of the locking recess, the two form halves of the sleeve separated by the slot, the two spring arms of the locking piece.
  • the connecting piece can protrude into a receiving groove of the bracelet, which extends centrally in the longitudinal direction of the tape from the free end of the tape, and the transverse web protrudes into the recesses of the bracelet on both sides of the connecting piece.
  • the crosspiece prefferably consist of two identical crosspiece halves which protrude symmetrically from one another into the recess of the connecting piece and each have a locking recess into which a locking piece can be inserted.
  • both cross bar halves are secured by a single securing part.
  • the crossbar has at its ends protruding from the connector an approximately rectangular crossbar with a round cross section of the part projecting into the recess of the connector, the crossbars can pivot in the recess of the connector. Their position relative to the bracelet remains unchanged.
  • Preventing the penetration of dirt into the recesses of the bracelet and protecting the bracelet in the region of the recesses is achieved in that the free ends of the crossbar facing away from the connector are provided with a radial widening.
  • the radial extension of the extension is preferably greater than the diameter of the recess in the bracelet.
  • the extension can be decorated with jewelry be provided and therefore requires no additional devices for attaching the jewelry ornament.
  • the fastening device shown in the figures for a bracelet 1 on the housing 2 of a wristwatch has, opposite to the housing 2, protruding integrally formed with the housing 2 connecting pieces 3, which protrude into receiving grooves 4 of the free band ends of the bracelet 1.
  • the width of the receiving groove 4 corresponds approximately to the width of the connector 3, while the depth of the receiving groove 4 corresponds approximately to the dimension by which the connector 3 protrudes from the housing.
  • Recesses in the bracelet 1 and a recess 5 in the connector 3 are arranged coaxially to one another and extend transversely to the longitudinal direction of the strip.
  • a crosspiece for the pivotable fastening of the bracelet 1, which is preferably designed as a leather bracelet, on the housing 2 is passed through the recesses in the bracelet and connector.
  • the crosspiece consists of two identical crosspiece halves 6.
  • the parts of the crosspiece halves 6 which are inserted into the recess 5 with a sliding fit are cylindrical, while the ends 7 protruding from the connector 3 have a larger, approximately rectangular cross-section.
  • the free ends of the crossbar halves 6 facing away from the connecting piece are provided with radial extensions 8 which have decorative ornaments and whose radial extension is greater than the diameter of the recess of the bracelet 1.
  • the ends of the crosspiece halves 6 facing the connector 3 are hemispherical for easy passage through the recesses of the bracelet 1.
  • radially circumferential annular grooves 9 are formed in the region of these ends on the cylindrical outer surface of the crosspiece halves 6, which form locking recesses.
  • openings 10 of cylindrical cross section are formed, the diameter of which corresponds approximately to the distance between the outer groove walls of the two annular grooves 9 from one another.
  • Locking pieces 11 can be inserted into the openings 10 from the side facing an observer and are formed with sleeves 15 of the same outer diameter as the inner diameter of the openings 10.
  • the sleeve 15 is closed by a closure part 12, which is provided with a decorative ornament.
  • the closure part 12 has a protruding projection 13 serving as a gripping piece, which is formed by a step-like diameter reduction of the end region of the sleeve 15.
  • This approach 13 which is in the installed state in the opening 10, is formed in its cylindrical outer surface with a radially circumferential groove 14, into which for dismantling a hook-shaped tool is engaged and the locking piece 11 can be pulled out of the opening 10.
  • the sleeve 15 of the locking piece 11 has a transverse slot 16, which is open towards the part of the sleeve 15 facing away from the closure part 12.
  • the width of the slots 16 is slightly smaller than the diameter on the groove base of the ring grooves 9, while the wall thickness of the sleeve 15 corresponds approximately to the width of the ring grooves 9.
  • the slots 16 are provided on their slot walls with recesses 17 which are located in the area of the ring grooves 9 when the locking piece 11 is mounted.
  • the depressions 17 have a contour corresponding to the contour of the bottom of the annular grooves 9.
