Definitions

  • the subject of the present invention is a clasp for a metallic bracelet made up of elements articulated together, in particular a watch strap, this clasp comprising a first part articulated at one of the ends of the bracelet on which is articulated an intermediate element having one end. angled in the shape of a hook and intended to engage behind a bar of a second part hinged at the other end of the bracelet to be folded back on the first part by pulling the second part of the clasp towards the first part and bringing part of this second part of the clasp engaged with a profile of the first part of the clasp.
  • a clasp of this type is known (LONGINES), the different parts of which consist of pieces cut and milled so as to allow them to be articulated with one another and at the ends of the bracelet.
  • the bar of the second part of the clasp engages in a countersunk groove in the first part when the intermediate element is folded over the first part.
  • This intermediate element being fixed to the notch on the transverse edge of the first part of the clasp, its bent part forms only a slight hook which retains only in an insecure way the second part of the clasp during an accidental opening of the clasp.
  • This clasp requires expensive machining and can only be used for one width of bracelet.
  • the object of the present invention is to produce a clasp without milling, by means of elements capable of being obtained by cutting off a profile and therefore allowing adaptation to any width of bracelet, respectively any width of articulated element of a bracelet.
  • the clasp must also offer better security on the one hand against accidental opening and on the other hand in case of accidental opening.
  • the two parts of the clasp and the intermediate element can be obtained, at the desired width, by cutting a bar, respectively a profiled tube.
  • the two elements respectively forming the first and the second parts are assembled to the bracelet like the articulated elements forming the bracelet.
  • the other end of the intermediate element has a hook which can be relatively deep and in which the bar of the second part of the clasp is securely retained in the event of accidental opening of the clasp.
  • the clasp consists of two parts 1 and 2 (6) respectively connectable to the two ends of a bracelet 3 (FIG. 7) consisting of three rows of metal elements hinged together by means of pins or pins in a known manner, and of an intermediate element 4.
  • Part 1 consists of two segments 5 and 6 identical sections, spaced from one another and connected together by three pins or pins 7, 8, 9 (FIG. 1).
  • an element 10 which connects the clasp to the bracelet 3 and which can be considered either as an element of the clasp or as an element of the bracelet.
  • On the pin 7 is articulated the intermediate element 4 shown in the open position of the clasp in FIG. 6.
  • Part 2 of the clasp consists of two profiled elements 11 and 12 spaced from one another and connected together by two pins 13 and 14, the pin 13 forming a bar.
  • an element 15 identical to the element 10 and also serving for the connection of the part 2 of the clasp to the bracelet.
  • the clasp in the closed position is integrated into the bracelet and shown in Figure 7.
  • the shape of the sections of elements 5 and 6, respectively 11 and 12 is visible in Figures 1 to 3.
  • the elements 5 and 6 of part 1 have, between the pins 7 and 8, a rounded groove 16 open upwards, while that the elements 11 and 12 have a similar groove 17 but open downwards.
  • These grooves 16 and 17 define with the ends of the elements opposite conjugate profiles such that when the ends of parts 1 and 2 are superimposed (FIG. 3), these conjugate profiles interpenetrate and marry perfectly so that the assembly obtained has the same thickness as each of parts 1 and 2.
  • the intermediate element 4 is in the form of a segment of flat tubular profile, that is to say having an oblong internal profile 18.
  • the total thickness of this profile is equal to the thickness of the elements 6 and 12.
  • the width of the internal profile 18 is substantially equal to the diameter of the pin 8.
  • the element 4 is provided with a transverse slot 19 whose width is slightly greater than the diameter of the bar 13 so as to allow easy passage of this bar through this slot.
  • the slot 19 located at a certain distance from the right end of the element 4, further defines a hook 20.
  • the profile 4 also has an auxiliary U-shaped profile welded to the profile 4 and forming a passage for the pin 7 around from which element 4 is articulated.
  • the closure of the clasp operates as follows: the bar 13 of the part 2 is engaged in the intermediate element 4 through the slot 19 and enters the bottom of the hook 20 in which it is retained with relatively great security.
  • the intermediate element 4 is then lifted by its straight end (FIG. 2), which has the effect of sliding the bar 13 in the profile 18 in the direction of part 1 of the clasp until the end of the part 2 comes into abutment with the end of part 1.
  • the profiled end of part 2 is passed over the end of the conjugate profile of part 1 so that these two parts of conjugate profiles fit together as shown in Figure 3.
  • the end of the hook 20 finally abuts against the pin 8 but can however exceed it by being elastically deformed by a slight pressure on the element 4.
  • This element 4 is also supported by its right part on the pins 8 and 13 so as to finally match the profile of the other elements of the clasp and the bracelet.
  • the closed clasp is perfectly integrated into the bracelet and it can be produced in such a way that it is difficult to distinguish these elements from the elements constituting the bracelet.
  • This clasp also has great security against accidental opening. Indeed, the end 22 of the intermediate element 4 is located at a certain distance from the pivot axis of this element 4. In the event of accidental detachment of the hook 20 from the bar 8 and lifting of the element 4 , its end 22 indeed abuts against the wrist of the wearer and a special effort is required to overcome this resistance. If despite everything the element 4 succeeds in tilting more than 90 ° to fall back into the position shown in FIG. 1, the bar 13 is still well retained at the bottom of the hook 20. Despite its simplicity, this clasp is therefore of great security.
  • FIG. 4 represents an alternative embodiment of the profile constituting the intermediate element 4.
  • this alternative 4 the passage for the hinge pin 7 is formed by a folded part 23 from the edge of the slot 19.
  • FIG. 5 A third embodiment of the intermediate element is shown in FIG. 5.
  • This element 4 "here consists of a more solid section segment than in the previous embodiments.
  • the passage for the pin 7 is formed here by two grooves in an arc 24 and 25 forming a partial circle
  • the groove 19 also has inclined faces facilitating the insertion of the bar 13 while having a slot opening as small as possible, which further increases safety.
  • the end of the clasp close to the slot also has a groove 26 facilitating the gripping of the element 4 "by the tip of the finger or by the nail.
  • FIG. 8 illustrates another example of a metallic bracelet made up of relatively very wide central elements 26 and relatively very narrow lateral elements 27 and 28.
  • the corresponding clasp consists of an intermediate element 4 of the same width as the elements 26, while the elements 5, 6, 11 and 12 of the clasp consist of elements of the same width as the elements 27 and 28.
