Definitions

  • the present invention relates to the field of fixing straps to watch cases, and more particularly to devices allowing easy change of the strap.
  • watch cases are known in which the strap is fixed by pinching between two parts of the case, whether this strap is formed by two separate strands, or by two strands connected together by a middle part having an opening corresponding to the shape of the box, or the shape of part of the box.
  • patent FR-504,267 Rubattel and Weyermann SA describes a watch whose bracelet made up of a rectangular band in one piece has a round opening which reveals the dial, the inside edge of the opening of the bracelet being enclosed between the middle and an attached bezel. In this way, the bracelet covers the entire box, except for the glass and the dial.
  • Another device of the same kind is presented in patent FR-1,598,983 Ervin Piquerez.
  • the bracelet does not cover the box.
  • the edge of its central opening follows the outside shape of the case, and is pinched between the middle and a ring screwed either on the upper part of the middle or on the bottom.
  • the purpose of these devices is essentially to avoid the presence of horns intended for fixing the bracelet, for mainly aesthetic reasons.
  • the assembly and disassembly of the bracelet from the case, whether done by screwing or even notched, requires a key or a tool and can hardly be done, in practice, except by a professional. This is all the more the case since, in most of the examples given above, disassembly exposes the internal organs of the watch.
  • the known devices cannot therefore apply to watches sold with several interchangeable straps, which must allow the consumer to change the strap himself.
  • the present invention aims to provide a watch case with strap which allows the user to easily change the strap, without special tools, and without the need to provide the box with horns.
  • the watch case with bracelet comprises at least one back with at least one groove 2 in which a part of the bracelet 3 is inserted and at least one closing element 4 which comes to close said groove and hold the bracelet there, and is characterized in that the closing element 4 is fixed to the bottom by means of a bayonet device having at least one lug 5 coming to be inserted in at least one corresponding recess 6.
  • the watch case with bracelet described above is characterized in that the groove 2 is annular and goes around the bottom.
  • the watch case with bracelet is characterized in that at least one housing 7 is formed in the edge 8 of the groove 2 or / and in the upper face 9 of the closure element, said edge 8 and said upper face 9 enclosing the bracelet, a compression seal 10 being placed in said housing and dimensioned so that the closure of the element 4 compresses the bracelet against said seal.
  • the watch case with bracelet according to the invention is characterized in that the recess 6 is continuous and in that at least one cleat 11 is placed in said recess so that at least one lug 5 abuts against said cleat when the closing element 4 is put in place.
  • the watch case with bracelet according to the invention is characterized in that the bracelet 3 is formed of a single part having between the two strands an annular part 12 shaped so as to insert at least partially into the annular groove 2.
  • Figure 1 is a partial vertical section of a box with bracelet according to the invention.
  • Figure 2 is a bottom view of a closure element according to the invention.
  • Figure 3 is a bottom view of the bottom of the box.
  • Figure 4 is a side view of the same bottom of the box.
  • Figure 5 is a perspective view of the closure element.
  • Figure 6 is a perspective view of the box mounted with the bracelet, the latter being shown only partially.
  • the bracelet 3 is in one piece, the two strands being connected to each other by an annular part 12.
  • This annular part has an opening, suitable for receiving a part of the bottom 1 of the box.
  • This part of the bottom is delimited laterally by an annular groove 2.
  • Below this annular groove is formed a recess 6 which, in the embodiment shown here, goes around this part of the bottom 1.
  • a notch 15 is made below the recess 6, at three points of an adjacent flange 14 in the hollow.
  • the annular part 12 of the bracelet is placed in the annular groove 2.
  • a closing element of annular shape, and having radially, directed inwards, three pins 5, comes to close the annular groove, the three pins being introduced into the recess 6 by the notches 15.
  • the annular part 12 of the bracelet is then trapped between the upper face 9 of the closure element 4 and the edge 8 of the groove 2.
  • we rotates the closure element so that the pins move laterally and are fully enclosed between the flange 14 and the other wall 16 of the recess.
  • a cleat 11 is fixed in the recess 6, here in the form of a cylindrical key driven into a radial hole made in the bottom of the recess.
  • the cleat 11 blocks the rotation of the closing element 4 in the closing direction, it has no effect in that of the opening. In order to avoid inadvertent opening, it is therefore necessary to prevent the closing element from sliding in the other direction.
  • compression which must be exactly dosed, requires on the one hand that the bracelet is made of a compressible and / or deformable material, and on the other hand that its thickness is machined very precisely. The first requirement is not met in the case of a metal bracelet, and the second is very difficult to achieve in practice.
  • the closure of the element 4 compresses the seal via the annular part 12 of the bracelet, this part then exerting friction on the upper face 9 of the closure element, preventing the latter from rotating in the direction of the opening.
  • Radial grooves 16 are formed on the underside of the closure element, in order to ensure sufficient grip for the fingers of the user who wishes to change the bracelet.
  • circular notches 13 and 17 are provided respectively in the bottom and on the upper face 9 of the closure element and face each other, so that bulges of corresponding shape of the bracelet come s '' to insert, which gives more firmness to the fixing of the bracelet to the box.
  • the box can have several bottoms, for example superimposed
  • the fixing device can have several annular grooves
  • the bracelet can be formed by two separate strands, case in which there can be two grooves
  • the device can include several elements closing, or a single lug instead of three, in which case the lug must have a sufficient angular dimension; finally, the recess which receives the lugs can be divided into several segments instead of being continuous.
