Definitions

  • the invention relates to a link bracelet, in particular for wristwatches, with articulated individual links, with a first single link on its one side facing an adjacent second single link, a lugs formed by mutually parallel, longitudinal directions of the strap, towards the adjacent second single link has an open guide shaft, between the two longitudinal walls of the band extending a guide part of the adjacent second single member projecting into the guide shaft and resting on its two side walls about a pivot axis extending transversely to the longitudinal direction of the belt, which is guided in the region of the guide shaft through holes in the adjacent individual links is passed.
  • the object of the invention is to provide a link bracelet of the type mentioned that is easy to assemble and is removable and has a structure requiring few simple components.
  • a sleeve is arranged in the through bore of the guide member, the outer diameter of which is larger than the diameter of the through bores formed in the lugs, and that the sleeve holds the pivot axis by friction or non-positive engagement on the pivot axis is.
  • a sleeve is inserted into the through bore of the guide part of a second individual element and this individual element is inserted with the guide element into the guide shaft of a first individual element. Now a pivot axis is pushed through the through bores of the lugs and the guide part, whereby it is also passed through the bore of the sleeve.
  • the sleeve is held on the swivel axis by friction or force flow and forms stops with its free ends, which abut the side walls of the guide shaft and thus prevent the swivel axis from moving automatically out of its installed position.
  • the swivel axis only needs to be pushed out of the through bores and the sleeve by means of a mandrel, the holding force of the sleeve on the swivel axis being overcome by the pushing force.
  • Both assembly and disassembly can be carried out easily by hand, but also in a simple manner in one device. This enables automated assembly and disassembly.
  • swivel axes can be used with a length corresponding to the width of the individual links without it can come to a lateral protrusion of the pivot axes from the individual links.
  • the sleeve is a spring pin-like, longitudinally slit tube cylinder which can be arranged on the pivot axis with a radially inward spring tension.
  • the sleeve is arranged with radial play in the through bore of the guide part, then when two individual members pivot relative to one another, there is friction between the cylindrical wall of the through bore of the guide part and the cylindrical outer surface of the sleeve. Since these two surfaces are relatively large due to the large diameter and the long length, the surface pressure between these surfaces and thus the wear are very low. In this way, the susceptibility to defects of the belt is kept low.
  • this design enables the sleeves to expand freely when the pivot axis is inserted.
  • the pivot axis can be connected to a chamfer at its free ends.
  • the sleeve engages when the swivel axis is inserted when the correct installation position is reached.
  • the pivot axis can consist of two partial axes, each of which protrudes through a through bore of the attachment and part of the through bore of the guide part.
  • the individual links are made of titanium and the sleeve and / or the swivel axis are made of silver or if these are silver-plated on their surface, there is only little wear on the link bracelet and thus less susceptibility to defects.
  • a link bracelet consisting of three individual links 1 is shown.
  • the individual links 1 have on their one side facing the adjacent single link 1 a guide shaft 2 which is open towards this single link 1 and is formed by two mutually parallel lugs 3 directed in the longitudinal direction of the link bracelet.
  • a guide part 5 protrudes into the latter, which is formed so as to protrude from the adjacent individual member 1.
  • bores 6 and 7 extending transversely to the longitudinal direction of the band coaxially to one another through the lugs 3 and the guide shaft 2.
  • the bore 7 of the guide lug has a significantly larger diameter than the bores 6.
  • a sleeve 8 Arranged in the bore 7 is a sleeve 8 designed as a dowel-type tubular cylinder with a longitudinal slot 11, the length of which corresponds approximately to the width of the guide part 5 and which has radial play in the bore 7.
  • the outer diameter of the sleeve 8 is larger than the diameter of the bore 6, so that the sleeve 8 is in contact with its end faces on the side walls 4.
  • pivot axis 9 Through the bores 6 and the bore of the sleeve 8, bolt-shaped pivot axes 9 are passed, the length of which corresponds approximately to the width of the individual links 1. In its area located in the bore 8, the pivot axis 9 has a slightly smaller diameter than in its area located in the holes 6. In this area of smaller diameter, the sleeve 8 surrounds the pivot axis 9 with a radially inward spring tension and is thus held non-positively on the pivot axis 9.
  • the pivot axis 9 has a chamfer 10 in its free ends.
  • the individual members 1 have rectangular face plates 12 covering the guide shafts 2 and guide parts 5 on their upper side.
