Description

  • The present invention relates to a watch comprising complementary means for ensuring the holding and instantaneous locking / unlocking of at least one of the ends of a link, such as a bracelet, said means being integral with two elements of said watch arranged to rotate relative to each other.
  • An important element of the clothing of a wristwatch is the bracelet allowing to fix it around the wrist, in the same way for a medallion watch it is the chain by which it is suspended around the neck or for the watches of the type brooch suspended by a flexible link intended to be hung on a garment, the chain or the flexible link constitutes one of the aesthetic elements of the watch. The evolution of manners and fashion has created new needs, in particular with regard to changing the bracelet or even the flexible link of a pin watch, or the chain of a medallion watch to adapt it, i.e. to circumstances or clothing, either fashionable. Apart from the fancy watches which are often sold with bracelets of different colors associated with a bezel or other means allowing a rapid change of the bracelet and the bezel which has a color matching the bracelet, watches of a certain quality always use conventional strap fixing means, namely horns or protrusions with a housing for the end of the strap which is made of leather or metal and the strap cannot be changed instantly by the user. Often the user must contact either the technician to change the bracelet or he must use one or more suitable tools to do the same job.
  • Another element of the strap of a watch which sometimes poses problems is the buckle, in particular concerning the metallic bracelets, because during the lengthening according to the turn of the wrist of the user, it is necessary to take care to shorten the two strands of the bracelet of the same length so that the buckle is always positioned in the right place. Regarding leather bracelets, the fact of having each time that we put or take off a watch to unhook the end of a strand and slide it into the loop causes some wear of this end which is annoying especially when it is a quality and expensive bracelet.
  • In FR-A-709 518, a watch or jewelry has been proposed mounted so as to be able to pivot on a plate, connected to one end of a bracelet and comprising on the opposite side, a hook in which one can engage a loop secured to the other end of the bracelet. The watch or the central jewelry has a shape such that in a certain angular position the hook is released, allowing the bracelet to be unhooked and in another position, the hook is blocked ensuring the locking of the bracelet.
  • In CH-A-216 721, a watch has been proposed, the frame of the case having a diameter smaller than the bottom making it possible to house a support ring provided at two diametrically opposite points with two hooks. At two diametrically opposite points, the telescope is also provided with two noses. The support ring is grooved to allow the winder to pass and allow the watch to rotate to release the noses in which the ends of a bracelet are housed.
  • In FR-A-1 151 234, a watch case has been proposed which has, in its cylindrical side wall, a groove and a slot in which a semi-cylindrical intermediate piece provided with a tongue extending outwards of the box can move freely. The tongue leaving the box through the slot is capable of covering or uncovering the clasp of the bracelet which is formed by a hook secured to the watch box.
  • The devices proposed in these three documents make it possible either to quickly change the strap of a watch, or they offer clasps for wristwatches and require special manufacturing and intermediate parts whose placement and function can have harmful consequences. on certain qualities of a watch, for example accessibility. inside the box or sealing.
  • In CH-A-371 055, a wristwatch has been proposed formed from two independent parts, one comprising a middle part with a base and the other comprising a horn support constituted by a flat circular ring. In each horn a housing intended to receive a ball and a spring is formed. The middle part has for its part two recesses intended to come opposite the housings of the horns, thus the balls pushed by the springs can enter there. An anti-shock mounting is obtained for the middle part suspended in the horn support.
  • In EP-A-270 947, a watch with a metallic rotating bezel has been proposed, provided with a toothed ring in synthetic material and fixed to the notch with the rotating bezel and mounted to notch on the middle by means of a ring. The toothing of the ring cooperates with a pawl mounted in a groove of the middle part.
  • The present invention proposes to overcome the drawbacks of existing constructions concerning the rapid change of a bracelet or any other link of a watch as well as to eliminate the problems caused by conventional loops of a wristwatch by combining constructions which are known and mastered by those skilled in the art but never with the aim of obtaining a rapid change of bracelet or as a loop of a wristwatch.
  • The watch case according to the invention is characterized in that one of said elements is a rotating bezel and the other the middle part of the watch.
  • The advantage of the watch case according to the invention, which mainly concerns a wrist watch box, but also a pin watch suspended by a flexible link or even a medallion watch is that the holding of one of the ends of the flexible link and locking with the box are provided by means complementary to the rotating bezel and the middle arranged to allow instant unlocking and locking. Thus, to achieve this result, the rotating bezel and the middle are assembled so that the bezel can rotate at least a few degrees around an axis perpendicular to the plane of the watch dial. This assembly thus allows the locking and unlocking of the end of the link by simple rotation of the telescope by a few degrees, this rotation allowing the removal of the complementary means or their bringing together to unlock respectively lock the holding of the end of the link, in particular of the bracelet.
  • Several alternative embodiments can be carried out, always remaining in the spirit of the invention, that is to say holding and locking the end of a flexible link are ensured by the collaboration of complementary means being found in on the one hand, on the middle and on the other hand, on the bezel. Their arrangement as well as the assembly of these two parts being designed to allow instant locking and unlocking.
  • Different exemplary embodiments will now be described with the aid of the accompanying drawings.
  • Figure 1 is a schematic plan view of a watch case and the ends of a bracelet in the unlocked position.
  • Figures 2 and 3 are views similar to the previous of an alternative embodiment.
  • Figure 4 is a view similar to the preceding of a wristwatch with two pairs of horns.
  • FIG. 5 is a view of an alternative embodiment of FIG. 4.
  • Figure 6 is a view similar to the others of another alternative embodiment.
  • Figure 7 is a 12h - 12h sectional view mainly showing the bezel-middle part assembly.
  • In all of the embodiments which we will describe below, the bezel is rotatably mounted on the middle in a known manner. An example of such an assembly will be described using FIG. 7.
  • In FIG. 1 is shown schematically a watch middle 1 provided with two lateral protuberances 2 and 3 each being provided with a groove 4, 5 intended to receive the rod 6 of a strand of bracelet 7. On the middle 1 is mounted a rotating bezel 8 by means which we will describe later. The bezel 8 is also provided with two lateral protuberances 9, 10 whose shape is complementary to the two protuberances 2 and 3 of the middle part.
  • To hang the strand of a bracelet 7 on the watch, the bezel 8 is rotated a few degrees so as to release the two protrusions and in particular the two grooves 4 and 5, the rods 6 are engaged in the grooves and this for the two strands and the bezel 8 is turned in the opposite direction to superimpose the protrusions 9 and 10 on the protrusions 4 and 5, so the ends of the bracelet are held, on the one hand, by the grooves 2 and 3 and, on the other part, locked by protrusions 9 and 10.
  • By this simple means, that is to say by turning the bezel a few degrees, it is very quickly possible to change a bracelet whether it is a leather bracelet or a metallic bracelet provided that its ends are provided with 'a rod 6. In order to avoid untimely unlocking, a means has been provided between the bezel 8 and the middle part 1 preventing the bezel 8 from inadvertently turning, which will be described with the aid of FIG. 7 later. When one wants to obtain the unlocking of the ends of the bracelet, it is necessary to apply to the bezel a relatively high moment of rotation at least compared to that which can occur inadvertently or accidentally.
  • In order to prevent the rods 6 of the bracelet from being able to disengage very easily when the bezel 8 is in the unlocked position, said grooves can be made so that their walls are oblique, that is to say that they fall into the thickness of the protrusions towards their free ends.
  • In Figures 2 and 3 we have shown the same watch case and used the same references to indicate the same elements. In this case, the bezel is provided with an intermediate protuberance 11 which can easily correspond to the protuberance that is found in certain cases protecting the crown of the winding or time-setting stem. This protuberance 11 is useful when one wants to avoid the use of a conventional buckle, so to remove a watch worn on the wrist, it suffices to turn the bezel 8 by 90 ° so that the protuberance 11 comes opposite the protuberance 3 or possibly 2 so as to ensure the locking of one of the two protrusions and release only one of the two, in this case the one bearing the reference 2, in order to be able to unhook the bracelet. We therefore proceed in this way to remove or replace a wristwatch around the wrist without having to use a buckle.
  • It is obvious that one could also imagine a bezel 8 provided with a single protuberance allowing only one end of the strap to be unlocked, thus the rotation of the bezel 8 corresponds to the opening or closing of a watch loop. bracelet.
  • In FIG. 4 we have shown a watch case 12 provided with two pairs of conventional horns 13, 14, 15 and 16, each being provided with a notch 17 provided for receiving the rod 18 of a watch strap 19. A bezel 20 is mounted in the same way as above on the middle part and it is also provided with four projections 21, 22, 23 and 24 of a shape complementary to that of the horns 13 to 16 of the middle part. After having put the rod 18 in the notches 17 of the four horns, the bezel 20 is turned so that the projections 21, 22, 23 and 24 are superimposed on the horns 13, 14, 15 and 16 thus obtaining the locking of the ends of the bracelet. Here too, a device prevents inadvertent rotation of the bezel 20 to avoid accidental unlocking.
  • It is also possible to have a bezel provided with only two projections, either 21, 22 or 23, 24, so that the bezel takes the place of a loop and not of an element allowing the rapid change of a bracelet.
  • In FIG. 5, we have represented another alternative embodiment similar to that described in FIG. 4, that is to say that the watch case 30 is also provided with two pairs of horns 31, 32, 33 and 34 but this time the diametrically opposite horns 31 and 34 are provided with a notch 35, 36 while the horns 32, 33 are provided with a hole, blind or not, 37, 38. A bezel 39 is mounted on the middle as before and it is provided only with two projections 40, 41 of complementary shape to the horns 31 and 34 provided with notches 35, 36. Here to change the bracelet, slide one end of each rod into the hole 38, respectively 37 and place the other end in the notch 35, respectively 36 which will be locked by turning the bezel 39 so that the projections 40 and 41 are superimposed on the horns 31 and 34.
  • In FIG. 6, we have shown a last alternative embodiment of a watch case 50 provided with two lateral protrusions 51 and 52 provided with a recess in the form for example of a dovetail 53, 54 intended to receive the end of a bracelet strand 59 of corresponding shape, while a rotating bezel 55 is provided with two projections 56, 57 which are superimposed on the protrusions 51, 52 to lock the end of the bracelet as before. From the examples described above, it is possible to imagine several variants which do not depart from the spirit of the invention.
  • In Figure 7 is shown a 12h-12h sectional view of an embodiment of the invention, this view is mainly presented to show a possible execution of the assembly of the rotating bezel on the middle bezel as well as a means preventing the rotating bezel to rotate inadvertently.
  • The watch case comprises a bezel middle 100, closed by a bottom 101, which can be screwed on, or driven off, housing a movement 103 and closed on the upper part of a glass 104. A rotating bezel 105 is mounted on the middle bezel 100, assembly is provided by a spring 106 forming a polygonal line and housed in two grooves 107 and 108 facing each other provided on the bezel 105 and the rotating middle 100.
  • The middle part of the bezel 100 is provided with a protuberance 109 provided with a recess 109a (like for example that of FIG. 1) intended to accommodate the rod 110 of a strand of bracelet 111 (similar to that of FIG. 1). The bezel 105 is also provided with a complementary protuberance 105a making it possible to lock the rod 110 in the recess 109a.
  • Of course, this execution of the rotating bezel can be applied to any execution of the preceding figures (horns, protuberances, dovetail, etc.).
  • To prevent inadvertent unlocking of the end of a link, one or more balls or nipples with a spherical head 112 can be provided each housed in a socket 113 set in the middle of the bezel and comprising an elastic means (for example a spring ) to push the ball or the nipple into a depression 114 in the telescope. Thus, when the depression 114 is facing the ball or the stud 112, the bezel 105 cannot be inadvertently rotated. A greater moment of rotation is necessary to close the bezel 105 and cause the ball or the stud 112 to exit from the depression 114. Of course, other means for locking the bezel in rotation can be used.
  • Although we have mainly described wristwatches here, it is obvious that the invention can be used for pin watches suspended by a flexible link and in this case instead of having two protrusions or two pairs of horns etc. just have one. The object of the invention is to be able to change the link, for example to accord it to the clothing or circumstance. Similarly, one could instead of a brooch watch have a medallion watch and use the invention in the same way.
  • Depending on the clothing of the watch, alternative embodiments are possible, for example the rotating bezel can be provided with two notches, instead of two protrusions, which must be positioned facing the housing provided in the middle by the ends. of the bracelet to unlock the bracelet.
