Definitions

  • the invention relates to a link band, in particular for wristwatches, with articulated individual links, each individual link having on its one side facing an adjacent individual link a guide shaft open to the adjacent single link, between which two side walls extending in the longitudinal direction of the band have a protruding, in the guide shaft projecting and resting on its two side walls of the adjacent individual link is pivotally guided a pivot axis extending approximately transversely to the longitudinal direction of the belt.
  • the known link bracelets have the disadvantage that hair of the wearer of the link bracelet can be clamped between the adjacent individual links, which is uncomfortable and painful for the wearer.
  • the object of the invention is to provide a link bracelet according to the preamble, in which wear of the individual links is kept low.
  • the pivot axis can be arranged in a bore extending through the individual links over the entire range.
  • the pivot axis can consist of stub axles which protrude approximately transversely to the longitudinal direction of the tape on the lateral guide surfaces of the guide attachment or the guide shaft and extend into corresponding recesses on the lateral guide surfaces of the guide slot or the guide attachment.
  • the stub axles can preferably be moved counter to a spring force in the direction of their longitudinal axis into axle bores which open into the guide surfaces on the guide shaft or on the guide shoulder.
  • the axis bore can be a through hole that extends transversely to the longitudinal axis of the band through the guide extension, between the out of the mouths a compression spring is arranged in the axle bore.
  • the axle bore can be a bore, on the bottom of which a compression spring is supported, through which the axle stub can be pressurized at its area projecting into the axle bore.
  • the stub axles can be arranged either in the guide shoulder or in the side walls of the guide shaft.
  • the compression spring cannot be lost during assembly and disassembly, it can be fastened in the axle bore, this being done in a particularly simple manner in that the compression spring in its region facing away from the axle stub has a larger outside diameter than the inside diameter of the axle bore and thus with Non-positive connection is held in the axle bore.
  • the compression spring can be attached to the stub axle.
  • the winding of the compression spring resting against the stub axle can enclose a coaxially protruding retaining pin of the stub axle. It is particularly safe here if the retaining pin has a radially circumferential annular groove into which the turn of the compression spring resting on the stub axle can be snapped.
  • stub axles arranged on the guide shoulder in that the mouth of the guide shaft directed in the longitudinal direction of the band with the guide shaft-extending ramp-like inclines is formed.
  • the stub axles are pushed into the shaft bore against the spring force by the bevels when the guide attachment is inserted into the guide shaft.
  • the stub axle is guided in the axle bore in a manner secured against rotation and has a ramp-like slope facing the adjacent individual member at its end protruding from the axle bore.
  • the single link has on its upper side facing away from the arm of a wearer a cover plate protruding in the longitudinal direction of the tape, which covers a guide surface extending approximately in the longitudinal direction of the tape on the upper side of the adjacent one Single link in the system. Due to the large guide surface that is possible, wear is kept very low.
  • the individual member has on its upper side facing away from the arm of a carrier a cover plate which at least partially covers the guide shaft and which is located on a guide surface extending approximately in the longitudinal direction of the band on the upper side of the guide extension of the adjacent one Single link in the system.
  • the guide surface is an arcuate surface which extends from the top of the individual link to the end of the individual link, the arcuate surface preferably having a radius whose radius axis corresponds approximately to the pivot axis.
  • the curved surface can merge into a stop surface approximately tangential to its radius, which extends to the end of the individual link.
  • the pivoting limit of the cover plate comes to rest on this stop surface. This limitation of the pivotability of the individual links makes it possible to make the play between the end faces of the individual links so small that the mutual contact of the end faces of the individual links is just avoided.
  • one or more guide pins protrude in the longitudinal direction of the band, which protrude with play into corresponding recesses on the corresponding end face of the adjacent single link, the recesses preferably being approximately conical, are formed with a cross section widening towards the end face.
  • the extent to which the guide pin can be pivoted in the recess also determines the extent to which the individual members can be pivoted.
  • the single member and the cover plate are in one piece, wherein preferably the single link and the cover plate are an embossed part.
  • the individual links in the area of the swivel axis or the stub axle projecting into the recesses can have decoupling openings extending outwards from the recesses transversely to the longitudinal axis of the swivel axis.
  • a decoupling pin can be inserted into the coupling openings to move the swivel axis or the stub axles.
  • a simply constructed and easy-to-use decoupling tool for a link bracelet of the type described above consists in that a decoupling pin has a width which corresponds approximately to the length with which the pivot axis or the axle stub protrudes into the corresponding recess, and at its one free end is provided with a ramp-like slope.
  • the decoupling pin When the decoupling pin is inserted into the decoupling opening, the swivel axis or the stub shaft is displaced in its axis bore by the ramp-like bevel, so that only the individual links have to be removed from one another.
  • the plate-shaped individual members 1, 1 ', 1' ', 1' ' shown in the figures have on their adjacent individual members 1, 1 ', 1' ', 1' '' facing end faces 2 and 2 'a central, to Adjacent individual link 1, 1 ', 1' ', 1' '' open guide shaft 3 into which a correspondingly formed guide shoulder 4 of the adjacent single link 1, 1 ', 1' ', 1' '' protrudes.
  • the side walls 5 of the guide shaft 3 and guide extension 4 extend parallel to each other in the longitudinal direction 6. While there is a larger game 7 between the end faces 2 and 2 ', the game between the side walls 5 of the guide shaft 3 and guide extension 4 is just so large that d the guide shoulder 4 can be pivoted easily in the guide shaft 3 about a pivot axis.
  • This pivot axis extends in the area of the guide shaft 3 and guide shoulder 4 approximately transversely to the longitudinal direction of the band 6.
  • the stub axles 8 arranged in the axis bores 9, 9 ', 9' 'of the guide shaft 4 and forming the pivot axis protrude from the axis bores 9, 9', 9 ' 'Out and in corresponding transverse to the longitudinal direction 6 extending recesses 10 on the side walls 5 of the guide shaft 3 into.
  • These recesses 10 are open toward the underside of the link bracelet facing an arm (not shown) of a wearer and are partially covered toward the opposite top.
  • the axle bore 9 '' is a continuous recess in which a single compression spring 11 'is arranged, which abuts with its ends on the end faces of the ends of the stub axles 8' in the axle bore 9 ''.
  • axle bore 9 '' to the top of the single member 1 '' ' is open, so that this single member 1' '' can be manufactured as an embossed part.
  • the stub axle 8 shown in FIG. 8 ' has at its end projecting into the axle bore 9 or 9' a coaxial retaining pin 12 with a radially circumferential annular groove 13.
  • the stub axles 8 and the axle bores 9 are inclined in the longitudinal direction of the tape in such a way that the outwardly directed end faces of the stub axle 8 form ramp-like bevels 17 pointing towards the guide shaft 3, through which the guide lug 4 is inserted into the guide shaft 3 as a result Axle stumps 8 are moved into their axle bores 9.
  • FIGS. 1, 2, 4, 5, 6 and 7 have on their upper side on the side of the guide shoulder 4 a cover plate 18 which projects in the longitudinal direction 6 of the belt alongside the guide shoulder 4.
  • the cover plate 18 partially covers the guide shaft 3.
  • This cover plate 18 comes by pivoting the individual members 1, 1 'and 1' '' on stop surfaces 19 and 20 to the system.
  • the stop surfaces 19 and 20 are tangential continuations of arcuate surfaces, not shown, which start from the top of the individual member 1, 1 'or 1' '' and whose radius axis corresponds to the pivot axis.
  • the individual links 1 '' have no cover plates. To limit the pivotability of the individual links 1 '' they have a at their in the longitudinal direction 6 end face 2 '' protruding in the longitudinal direction 6 guide pin 21 which protrudes into a recess 22 on the corresponding opposite end face 2 of the adjacent individual member 2 '.
  • the recess 22 is approximately conical and has a cross section which widens towards the end face. This cone determines the amount by which the individual links 1 '' are pivotable.
  • a decoupling tool 23 which consists of a plate 24 whose thickness is equal to or less than the diameter of the stub axles 8 and 8 '.
  • the plate 24 has two parallel decoupling pins 25 which are arranged at a clear distance from one another which corresponds to the width of the guide projection 4.
  • the width of the decoupling pin 25 corresponds to the dimension which the stub axles 8 and 8 'protrude from their axle bores 9, 9' or 9 ''.
  • the decoupling pins 25 At their free ends, have ramp-like bevels 26 which are inclined against the decoupling movement of the stub axles 8 and 8 '.
