Definitions

  • the invention relates to a link bracelet, in particular a watch strap, with link rows made of band links lying next to one another in the cross-band direction, the adjoining band links of a link row forming gaps and projections, each offset by half their length in the longitudinal direction of the tape, and the projections of one link row into the Gaps protrude from the adjacent row of links, with hinge pins which protrude through recesses extending in the transverse direction of the tape in the two ends of the tape links directed in the longitudinal direction of the tape and are secured against axial displacement.
  • the object of the invention is therefore to provide a link belt according to the preamble, which is secured against unintentional detachment of the link belt parts from one another.
  • At least one end of the hinge pins on its area projecting into the recess of the outer band member has at least one radially resilient latching arm with a radially projecting latching cam which can be latched into a corresponding latching recess in the wall of the recess and in the latching position can be blocked.
  • This design enables simple assembly, in that the band links are pushed onto the hinge pins until the latching cam of the latch arm can be latched into the latching recess of the outer band link. The subsequent blocking of the locking cam in this locking position prevents unintentional loosening.
  • Such a connection can either be arranged only on one outer band link of a row of links or else on both outer band links of a row of links.
  • a simple and easy and inexpensive to manufacture is that the end of the hinge pin is provided with a coaxial bore, is tubular and has one or more radial slots, wherein a locking pin of the same outer diameter as the inner diameter of the coaxial bore can be used in the coaxial bore.
  • the latching cam is a projection that runs radially around the cylindrical lateral surface of the end of the pin, it can also be produced in a simple manner.
  • the latching recess is preferably an annular groove in the wall of the recess.
  • the recess of the outer band member can be produced by a simple drilling process if it is a stepped bore, the large step of which is directed towards the free side of the band member and forms the latching recess.
  • the recess of the outer band member can be a stepped bore, in whose large step facing the adjacent band member a sleeve can be used, the bore wall of which has a radially circumferential annular groove.
  • Another inventive design of an object according to the preamble is that at least one end of the hinge pins has an outwardly opening axial recess into which a latching element can be inserted, which has radially resilient latching arms with a radially projecting latching cam which fits into a corresponding latching recess in the wall of the recess can be locked and locked in the locked position.
  • This design also enables simple assembly, in that the band links are pushed onto the hinge pins until the latching cams of the latching elements arranged in the outer band link snap into the latching recesses of the hinge pins. The subsequent blocking of the locking cams prevents unintentional loosening.
  • a simple and easy and inexpensive to manufacture is that the locking element is provided with a coaxial bore, is tubular and a or at its end projecting into the hinge pin has a plurality of radial slots, wherein a locking pin of the same outer diameter as the inner diameter of the coaxial bore can be inserted into the coaxial bore.
  • the locking cam is a radially circumferential extension on the cylindrical outer surface of the end of the locking element which projects into the hinge pin, it can also be produced in a simple manner.
  • the latching recess is preferably an annular groove in the wall of the axial recess of the hinge pin.
  • the individual band links have a perfect guide and cannot tilt transversely to the longitudinal extent of the band link, but can only pivot about the hinge pins. This also prevents premature wear of the hinge pins.
  • annular shoulder is formed on the correspondingly designed hinge pin, on which the outer band link is securely guided, and between the inner band links for easy pivoting ensures required game.
  • the coaxial bore of the hinge pin can either be a blind bore or a continuous bore. If it is continuous, the locking pin and the hinge pin can have approximately the same length. In order to the coaxial bore is neatly closed at its mouths.
  • a simple mounting of the locking pin in its installation position consists in that the locking pin can be inserted into the coaxial bore by means of an interference fit.
  • the coaxial bore of the hinge pin is a threaded bore into which the locking pin provided with a corresponding thread can be screwed. Both versions also allow easy disassembly.
  • the coaxial bore is a stepped bore
  • the large step formed in the region of the outer band member opens out and the small step is designed as a threaded hole.
  • the locking pin can have a head at its end directed towards the edge region of the link belt, through which the preferably opening outward opening of the recess of the outer belt link can be closed, so that there is a closure that is both optically clean and prevents the ingress of dirt .
  • a further inventive design of an object according to the preamble consists in that at least one end of the hinge pins is provided with a coaxial bore and is tubular and has a portion protruding into the recess of the outer band member radially protruding locking cams engaging in a corresponding locking recess in the wall of the recess can be plastically deformed, the locking cam being lockable in the position engaging in the locking recess. In the simplest way, both assembly and securing against unintentional loosening are achieved.
  • the hinge pins has an outward-opening axial recess into which a latching element formed with an axial bore can be latched, which in its area protruding into the recess of the hinge pin has a radially projecting into a corresponding latching recess in the wall of the recess of the hinge pin engaging latching cams is plastically deformable, the latching cam being lockable in the position engaging in the latching recess.
  • the hinge pin or the Rastele element can be plastically deformable by a blocking pin that can be inserted into the coaxial bore or the axial bore, at least partially larger than the inside diameter of the undeformed coaxial bore or axial bore.
  • the section shown in Figure 1 shows a side region of a link belt.
  • the band links 1, 2 and 3 and 1 ', 2' and 3 ' which are adjacent to each other in the band transverse direction each form a row of links.
  • the adjoining band links of a row of links are each offset by half a length in the longitudinal direction of the band to form gaps and protrusions. The protruding jumps of one row of links into the gaps of the other row of links.
  • the band members 1, 1 ', 2, 2', 3 and 3 ' extend in the transverse direction of the band 4 and 5 through which the hinge pins 6 protrude.
  • the hinge pins 6 have continuous coaxial bores 7 into which the locking pins 8 are inserted with an interference fit. As can be seen particularly well in Figures 2 and 3a to 3d, the hinge pins 6 are provided at their ends in the outer band member 1 to 1 'projecting ends with radial slots 9 so that they can spring radially by a certain amount.
  • Figure 3c shows three evenly distributed radial slots 9, while Figure 3d has two continuous radial slots 9 arranged in a cross shape to each other.
  • FIG. 3d corresponds to the configuration in FIG. 2.
  • This locking cam 11th can be snapped into a locking recess 12, which is formed by an annular groove arranged in the wall of the recess 9.
  • the recess 4 of the outer band member 1 is a stepped bore, the large step of which is directed towards the adjacent band member 2 and into which a sleeve 13 e.g. is used under interference fit.
  • the sleeve 13 In its end area facing away from the band member 2, the sleeve 13 has a circumferential annular groove formed in its bore wall, which forms a locking recess 12 'into which the hinge pin 6 can snap with its locking cam 11.
  • the coaxial bore 7 of the hinge pin 6 is designed as a stepped bore.
  • the large step is formed in the area of the outer band link 1, while the small step located in the area of the inner band link 2 is provided with a thread 14.
  • the locking pin 8 ' is designed as a threaded pin with a slot 15 provided with head 16 and screwed into the thread 14.
  • the blocking pin 8 or 8 'inserted or screwed in by press fitting can also be removed again, and thus the belt members can be removed without being destroyed.
  • the locking pin 8 is not continuous, so that after inserting it with a press fit in the coaxial bore 7 can no longer be removed.
  • the locking pin 8 has a head 16 similar to the locking pin 8 ', both the head 16 and the head 16' closes the outward opening of the recess 4.
  • the hinge pin 6 ' projects through only the recesses 5 of the band links 2 and 3.
  • a circumferential annular groove is formed in the coaxial bore 7 thereof, which forms a latching recess 12 ".
  • a latching cam 11 can be snapped in, which is formed at one end of a latching element 17 inserted with its other end in the recess 4 of the outer band member 1 as a radially circumferential projection.
  • the locking element 17 has a coaxial bore 18 and is provided at its in the hinge pin 6 'projecting end with radially continuous slots 9.
  • the radially resilient locking arms formed in this way are blocked by a locking pin 8 ′′′ into their position locked in the locking recess 12 ′′.
  • the locking pin 8 ′′′ has an outer diameter corresponding to the inner diameter of the coaxial bore 18, and at its end projecting into the recess 4 an opening 4 closing this recess 4.
  • the locking pin 8 ′′′ can be press-fitted into the coaxial bore 18.
  • the hinge pin 6 also protrudes through the recesses 4 and 5 and has a coaxial bore 7.
  • the hinge pin 6 In the undeformed state shown in FIG. 8, the hinge pin 6 "projects with its cylindrical end piece into the bore 4.
  • the end region of the hinge pin 6 becomes a radially circumferential shoulder-like Stage 19 of the locking pin 8 "" larger outer diameter than the inner diameter of the coaxial bore 7 plastically deformed radially outwards, so that a locking cam 12 'protruding into the recess 12 is formed.
  • the locking pin 8 "" simultaneously represents a safeguard against unintentional loosening of the link belt parts from one another.
