Definitions

  • the present invention provides a piece of jewellery, such as a bracelet, a necklace or the like, consisting of two hinged arms or bars and spring means keeping the jewels in their locking position.
  • the jewel is characterized by the particular configuration of these spring locking devices, which, besides being aesthetically preferable to the ones known in the art, have the considerable advantage of preventing the skin from being pinched or pricked when locking the jewel.
  • the bracelet of the invention is provided with a spring member which, at one of its ends, is welded to the inside of one of the bars forming the bracelet, gets out of this bar a little before the hinge area and has the second end bent inwards and getting into a corresponding opening in the second bar.
  • a cam member is integral with one of the bars, said cam member having such a configuration that, when the bracelet is opened, the spring acts on this cam member to return the bracelet into its locking position.
  • the assembly has such dimensions that the bent end portion of the spring acts as a stop means to limit the excessive opening of the arms forming the jewel.
  • jewels in particular bracelets, necklaces, ear-rings or the like, comprising two folded arms or bars being hinged with each other at one end and being subject to the action of elastic means which keep them in their locking position, by tightening each against the other.
  • spring devices provide several advantages both for the manufacturer, who no longer needs clips or the like which imply functional problems and higher production costs, and for the user, for whom the jewel is much more practical since, to put it on or off, it is sufficient to open wide the arms which then are closed again due to the force from the spring.
  • a known embodiment which is disclosed, for example, in EP-A-0 375 565 and which is shown in figure 1, utilizes a spring located inside the arms, which are indicated with numerals 1 and 2 in figure 1.
  • the arms are joined by a hinge 3 and a spring 4 is placed inside, said . spring 4 tightening the arms each against the other.
  • a further known embodiment is provided with a spring member, an end of which is fastened, by means of rivets or the like, to the outer surface of one of the arms.
  • This spring member is then passed inside the bar, from which it gets out near the hinge to contact the second arm.
  • the embodiment with the inner spring has the drawback that the two hinged arm ends tend to pinch the user's skin when the jewel is closed and they do not keep opened wide when the user opens the jewel to put it on.
  • the second embodiment with the spring getting out of one of the bars to contact the second arm, is considerably complicated to assemble and it also has some drawbacks since, when the arms are opened, the spring end tends to move slightly away from the arm on which it rests, with the risk, when the jewel gets closed, of pinching or pricking the user's skin.
  • the present invention falls within this field by providing a jewel with improved spring locking devices which can overcome the above mentioned drawbacks.
  • a spring is used an end of which is welded inside one of the bars and gets out a little before the hinge, up to the other arm where the second, bent spring end gets into an opening in the arm wall.
  • a cam is provided which engages the spring whereby, when opening the arms, the spring, by acting on the cam, tends to close the jewel.
  • numeral 10 shows a jewel, specifically a bracelet, comprising a pair of arms or bars 12 and 13 joined by a hinge 14.
  • a spring member 15 acts on the arms 12 and 13 to keep them in their locking position.
  • an end of the spring member 15 is welded at numeral 16 to the inside of the two bars, it goes on inside the bar for a certain length and it gets out of the bar at an opening 17 near the hinge 14, to pass on said hinge and contact the second arm 13.
  • the spring end 18 is bent inwards and it gets into a corresponding opening 19 in the wall of the bar 13.
  • a cam member 20 being engaged by the spring 15 is integral with the bar 13.
  • the cam member 20 has an outline with two opposedly sloping inclinations on which the the spring acts respectively in the opening and closing position, so that the force from the spring tends to keep the bracelet respectively open or closed.
  • the spring tends to keep the bracelet in the opening or closing position by opposing the rotation of the arms 12 and 13 until the dead centre is passed, after which the spring opposes the motion in the opposite direction.
  • This configuration has several advantages with respect to the known embodiments, both from an aesthetic point of view, since only a part of the spring gets out of the arms, and only in the hinge area, and because the risk of skin pinching is considerably reduced, since the spring no longer moves away from the bracelet with the risk of pinching the user's skin when closing the bracelet.
  • jewels comprising a plurality of bars placed side by side a single pin may be provided which joins several bars, one or more of them receiving the springs which act on cams being integral with the pin and the second bar.
  • the dimensions, as well as the materials being used, may change according to the needs.
