Definitions

  • the present invention relates to a clasp for a watch strap. More specifically, the present invention relates to a clasp for a watch strap comprising means that allow fine adjustment of the length of the bracelet.
  • Clasps comprising means for a fine adjustment of the length of the wristband of a watch are already known from the state of the art.
  • Clasp for fine adjustment of the length of a bracelet means clasps that allow to adjust the length of a short strap to allow to fit the fairest length for optimal comfort when wearing the bracelet. shows.
  • Such clasps usually include a terminal link through which one of the strands of the bracelet is connected to the lid of the clasp. This terminal link is slidable in a longitudinal direction of the clasp between a first retracted position in which it is housed in the lid of the clasp and a second extended position in which it is disengaged from the clasp. Therefore, the length available for the fine adjustment is determined by the travel of the end link between its first and second positions.
  • the end link cooperates via a toothed element with a toothed rack.
  • the rack can be secured to the lid of the clasp and the toothed element be carried by the terminal link.
  • the permutation of the rack teeth and the toothed element is also possible.
  • the present invention aims to overcome the drawbacks mentioned above as well as others by providing a clasp for the fine adjustment of the length of a watch strap including maintaining the adjustment of the length of the bracelet without risk of losing it inadvertently.
  • the present invention relates to a clasp for a watch strap comprising a cover connected from one side to a first strand of a bracelet and from a second side to a second strand of bracelet, connecting means being interposed between the second strand of bracelet and the clasp cover, these connecting means comprising a sliding terminal link in a longitudinal direction of the clasp between a first position in which the terminal link is at least partially engaged in the clasp cover, and a second position in wherein the end link is disengaged from the clasp cover, the end member comprising a push-button on which it is possible to pass a toothed element from a first position in which the toothed element is engaged with a toothing.
  • the clasp integral with the clasp cover, at a second position in which the toothed element is released from its enga with the rack teeth, the clasp being characterized in that the terminal link comprises a housing in which is arranged at least one spring, this spring being capped by the pushbutton.
  • the present invention provides a watch strap clasp in which the disengagement between the toothed element and the rack teeth is controlled by at least one spring.
  • a spring provides the push button a substantial stroke, this stroke being determined only by the length of the spring.
  • the push button directly controls the passage of the toothed element from its first position in which it is engaged with the rack teeth to its second position in which it is released from its engagement with the rack teeth, the race of the toothed element between its two extreme positions is also larger.
  • the teeth of the rack teeth can be made higher than was the case in the state of the art and therefore the spaces between the deeper teeth.
  • the force of the notching between the toothed element and the rack tooth is therefore higher, so that the position of the end link can not be deindexed, except to destroy the clasp.
  • the manufacturing tolerances are less stringent, which allows for gains in terms of cost.
  • the push button is equipped with a stop means preventing extraction of the end link from the clasp cover.
  • the connecting means between the clasp cover and the second bracelet strand are captive, except to destroy the clasp.
  • the stop means can be dismantled, which makes it possible, if necessary, to replace the end link or the push-button when the wristwatch returns to service afterwards. sale.
  • the present invention proceeds from the general inventive idea of using a spring as an elastic means controlling the uncoupling between a toothed element and a toothed rack of a fine tuning link of a clasp for a watch band.
  • a spring provides a greater stroke to the pushbutton associated therewith, so that the displacement of the toothed element controlled by the push button from its first position in which it is engaged with the rack teeth at its second position in which it is released from engagement with the rack teeth is also more important.
  • the teeth of the rack teeth can therefore be provided higher with deeper teeth recesses, which ensures a better notch of the toothed element and reduces the manufacturing tolerances of the teeth of the rack teeth.
  • the figure 1 is a perspective view in the dissociated state of the clasp according to the invention while the figure 2 is a perspective view of this same clasp in the assembled state.
  • the clasp according to the invention comprises a lid 2 connected on one side to a first strand of bracelet 4, of which only one link is visible in the drawing with the interposition of a clasp closure 6 whose structure is known per se and therefore will not be described further here.
  • the clasp closure system 6 can be omitted and the cover 2 can be connected to the first strand of bracelet 4 directly.
  • the lid 2 is connected on the second side to a second strand of bracelet 8, three links of which are visible in the drawing with the interposition of a terminal link 10 for fine adjustment of the length of the wristband of the watch.
  • the lid 2 has a U-shaped general section and is provided with two flanges 12 facing each other, these flanges 12 each carrying on their inwardly directed face a rack toothing 14. Furthermore, a groove 16 is provided in the bottom of the cover 2 and defines two end stops 18 whose role will be described in detail later. Finally, the terminal link 10 comprises lateral guide surfaces 19 to be slidably guided in the cover 2 between the bottom of the cover 2 and the wings 12.
  • the end link 10 is capable of sliding in a longitudinal direction of the clasp 1 between a first position ( figure 2 ) in which the end link 10 is engaged in the cover 2 of the clasp 1, and a second position ( figure 3 ) in which the end link 10 is disengaged from the cover 2 of the clasp 1.
  • the length available for the adjustment of the bracelet is determined by the travel of the end link 10 between its first and second positions.
  • the end link 10 comprises two end knuckles 20 between which the middle knuckle 22 of the adjoining link of the second strand of bracelet 8 is interlocked.
  • the assembly between the links is ensured by a bar 24 freely traversing the knuckles 20 and 22 and which is held by two end screws 26.
  • the terminal link 10 comprises at least one and, preferably, two cylindrical blind housings 28 in each of which is disposed a helical spring 30, these springs 30 being capped by a push-button 32.
  • This push button 32 is substantially in the form of a rectilinear actuating bar which extends transversely to the longitudinal axis of symmetry of the clasp 1 and which has at each of its ends a toothed element 34 for example in the form of a half-cylinder. These toothed elements 34 are intended to come into engagement with the toothing of the racks 14. It will be understood that when the end link 10 and its pushbutton 32 are slid between the two wings 12 inside the cover 2 of the clasp 1 as illustrated.
  • the coil springs 30 which are mounted force the push button 32 towards the racks 14, so that the toothed elements 34 are engaged with the teeth of the racks 14. Conversely, when the push button 32 is depressed following the arrow A against the elastic return force of the springs 30, the toothed elements 34 are released from their engagement with the toothed racks 14. It will also be understood that the coil springs 30 give the push button 32 and therefore To the toothed elements 34 a large stroke, so that the teeth of the rack teeth 14 can be high and the spaces between these deep teeth. As a result, the toothed elements 34 are perfectly notched in the teeth of the racks 14, so that it is impossible to accidentally lose the setting of the end link 10. In addition, the requirements on the tolerances of the toothed racks 14 are smaller, which allows to realize gains in terms of production costs.
  • a first threaded through hole 36 in which is screwed a screw 38 whose tip projects into the groove 16 formed in the bottom of the lid 2.
  • a stop 18 which marks the bottom of the groove 16
  • the end link 10 of fine adjustment is completely captive once the screw 38 screwed.
  • a second through-hole 40 aligned with the first threaded through hole 36 is machined in the push-button 32.
  • a plug (not shown) is driven or glued into the second through hole 40 to hide the screw 38 and not to reveal a hole in front of the user.
  • the pushbutton 32 is permanently unmountable.
  • a screw 42 is screwed into the second through hole 40. This screw 42 masks the screw 38 with respect to the user. However, the assembly remains removable to the extent that it is sufficient to remove the screw 42 to then be able to remove the screw 38.
  • These two variants are preferred to the variant in which only one screw is provided that is long enough for the head of this screw is flush with the surface of the pushbutton 32. Indeed, in this embodiment, the head of the screw protrudes from the pushbutton 32 when it is pressed against the return force spring elastic 30, which is not aesthetic.
  • cylindrical blind housings 28 there will be noted that at the bottom of the cylindrical blind housings 28 are provided two pins 44 for centering the springs 30. Furthermore, the push-button 32 is provided on its surface facing the end link 10 of fine adjustment of two cylindrical housings 46 coaxial with cylindrical blind housings 28 for guiding and holding springs 30.
