Definitions

  • the subject of the invention is an articulated bracelet with links, in particular an articulated bracelet for watches, composed of a first set of articulated elements and a second set of elements framing the elements of said first set.
  • the invention also relates to an extension link suitable for use with this bracelet.
  • articulated bracelets of the kind indicated, namely those which include a first set of elements articulated to each other, forming the internal elements, also called “connecting links or” wagons •, and a second set of elements.
  • external called “locking elements or called, depending on their configuration," frames or “tunnels •, the elements of the two sets having substantially the same dimension in the direction of the length of the bracelet, the external elements surrounding or enclosing the internal elements.
  • the bracelet according to CH-A 630 789 comprises a first series of internal elements of generally parallelepiped shape each having a groove of circular section, opening on one of the transverse sides of each element and, on the opposite transverse side, a projection of circular section also.
  • the joint is formed by the introduction of the projection of an element in the groove of the adjacent element.
  • the bracelet comprises a second series of elements, namely the external elements, in the form of stirrups which are juxtaposed and cover the internal elements which they maintain assembled, preventing them from moving transversely.
  • the elements of the two series are bevelled on their transverse sides to allow limited movement around the axis of the projection.
  • the articulated bracelet described in CH-A 633 170 and, in an identical manner, in EP-A1 / 0 030 705, is formed of a chain of internal elements each having two transverse projections of straight cross section in L, oriented in direction reverse, and these elements are articulated to each other by reciprocal engagement of their projections.
  • the bracelet comprises a second set of elements in the form of frames which are juxtaposed and each engaged on one of the internal elements which they maintain assembled, preventing their projections from coming off from each other.
  • Said clearance between two external elements is, on the one hand, inevitable by the manufacturing data and, on the other hand, necessary so that two adjacent elements can form a small angle - generally of the order of 5 to 10 ° - allowing the bracelet, by folding, to follow the shape of the wrist, see figs. 2 and 3 of the cited patent.
  • the first object of the invention is to find a solution to the stated problems and to eliminate them. Another goal is to create a new construction of such a bracelet with 'links and tunneis ' . namely comprising a series of internal elements articulated to each other, and external elements ensuring the cohesion of the assembly and giving it its desired final shape and limiting the angle of bending between two adjacent internal elements. Yet another object of the invention is to develop this new construction with a view to a special execution of bracelets which are particularly decorative and which surprise the public by the appearance of a mechanical paradox in that they have the appearance the impossibility of conforming to a wrist because the shape of the ornament does not seem to lend itself to articulation. These include “wave” bracelets for which the applicant has protection by registered model.
  • a special object of the invention is the construction of the extension links allowing easy and problem-free adaptation of the length of the bracelet, without the whole bracelet running the risk of falling apart.
  • any element described or drawn and any combination of elements which is not technically proficient, can present an invention or contain inventive characters and can thus constitute without being said expressly, the base of additional claims .
  • this external element is joined, to form the "tunnel", by a special welding technique described and claimed in patent no. (Swiss patent application no. 5234/82, filed on 03.09.82) developed by one of the inventors of the bracelet according to the invention.
  • this technique allows welding between identical or different metals, and a solid, durable, robust bond that is relatively unassailable by corrosion is obtained.
  • the problem of the external elements being able to slide freely on the internal elements and being able to free the place of a hinge pin by accumulation of the clearance is solved according to the invention by a measure which prevents this free sliding but which not prevent disassembly of individual components even by an untrained person.
  • This measure consists in providing a partial frictional resistance between an internal element and the external element. In this way, the elements are held in place, and the limited longitudinal movement of each external element relative to its internal element is ensured, but this resistance must be overcome when one wants to mount and dismount the bracelet.
  • the extension links have a different construction.
  • the bracelet shown in Figure 1 is only one half, the other half being symmetrical to the first and connected to the latter by a special middle piece not shown.
  • a connecting piece to a watch case is also provided at the end of each half (not shown either).
  • elements 40 extending from elements 12 towards the middle part of the bracelet reveal screw heads which belong to threaded pins 13. These elements are then easily removable and serve, by their removal or by adding others, adapting the bracelet to a wrist given. These elements 40 are described below.
  • the detail of a link 14 is shown, in an enlarged perspective view, in Figure 3.
  • the body of the link 14 comprises four millings 16 which are distributed at an offset on the link so as to be able to receive the remaining tongues 18 of the next link, exactly like a hinge.
  • the meeting between two links is ensured by the pin 20.
  • This pin can have a diameter such that there will be friction in the bores 22 of the link, or a diameter such that there is a small clearance because the tunnel to be described prevents anyway the lateral exit of the pins. The latter execution is preferred.
  • the underside of the link 14 includes a narrowing portion 24 whose purpose will be described below.
  • FIG. 4 represents a clear perspective view of the two constituent parts of the tunnel 12; the external element 10 (FIG. 1) is constructed in the same way.
  • Bridge 26 is first prepared by machining and internal milling. The lower parts are bevelled at an angle A of between 5 ° and 10 °, generally around 8 °. This angle A will determine the degree of radial flexibility of the bracelet. An angle A exceeding 10 ° will result in an unaesthetic play between two elements when folding the bracelet, and an angle less than 5 ° is not enough for the bracelet to completely conform to the shape of certain wrists.
  • the upper faces 28 of the bridge are welded according to the method described in Swiss patent application no. 5234/82, to the cover piece called "wave 30, the underside of which is flat.
  • the wave can consist of noble metal, plated metal, or stainless steel for example. (It is obvious that according to the nature of the metals, when noble metal is used, it can have restrictions due to certain national legalizations.)
  • the interior of the tunnel thus formed is delimited at the bottom by a curved face 32 convex (it that is to say curved) which reflects the shape of a milling head during the machining of the bridge 26, or else this convex shape can be obtained by an adequate deformation of the lower part of the bridge which is preferred.
  • the dimensions and the lumen of the tunnel and of the link 14 are chosen such that the link 14, when it is introduced into the tunnel 12 or 10, finds a certain resistance as a result of the contact of the respective horizontal surfaces.
  • the face 32 of the tunnel is opposite and inside the recess 24 of the link, and the latter can move freely relative to the tunnel, however within the limits imposed by the width of the recess 24.
  • FIG. 5 represents a perspective view of a blank of the link 14. It is obtained by driving out a meniscus 34 in a rounded flat bush 36, or by welding or sticking it inside the bush 36. Milling according to the arrows 38 directly supplies the link 14.
  • FIGS. 4 and 5 have been introduced to demonstrate the great simplicity of the manufacture of the constituent elements of the bracelet according to the invention compared to that of similar previous bracelets.
  • the pins 20 When mounting the bracelet, the pins 20 (Figure 3) are inserted between two adjacent links 14.
  • the pins can be crimped or welded but this is generally not necessary because the pins 20 are prevented from leaving their housings by the presence from tunnel 12 (or 10).
  • the links 14 can make a pivoting movement, driving the tunnel, around the axis of their pins, thanks to the bevel A of the tunnel. With angles A of 8 °, the maximum pivot angle is therefore 16 °.
  • Figure 6 shows a perspective view of an extension link 40. (There is also a connecting link - between the last element according to Figure 4 and this extension link 40 - whose construction will be obvious to humans of career.)
  • This link 40 has a general shape similar to the element 12 ( Figure 4) except as regards the articulation.
  • a wave-shaped part 30 is welded to the upper planar faces 28 of the bridge 26A.
  • the surface 32 is flat, so it is not curved.
  • the upper part of the bridge 26A comprises two projections 42, 42A, symmetrical with respect to the vertical vertical plane.
  • the projection 42 is pierced by a bore 44 while the projection 42A comprises a threaded blind bore 44A.
  • Grooves 46 are provided on the rear faces of the bridge 26A, intended to receive the projections 42, 42A of the neighboring link 40.
  • a connecting link 14 (see FIG. 3) is inserted into the opening of the connecting link 40 which has just been described, and the dowel 13 is introduced first into the bore 44, then into the bore 22 of a connecting link, then in a bore 22 of the connecting link of the adjacent element, and finally the pin 13 is screwed into the blind bore 44A.
  • This execution therefore includes the simultaneous attachment of the external element and the internal element, which greatly facilitates the adaptation of the bracelet to a given wrist even by a low-skilled person.
  • the ornamental piece 30 can take other forms.
  • the angle A can be progressive, namely that the sides of the bridge 26 forming this angle can be rounded. All parts can be surface treated, chrome plated, plated etc.
  • the curved surface 32 of the part 26 (FIG. 4) can be concave instead of convex, which gives the same effect from the point of view of limited mobility with respect to the tunnel when the connecting link 14 has the lower face corresponding curved.
