Definitions

• a wristwatch intended to be worn on the wrist of a user.
• a wristwatch is a watch mounted on a bracelet which can be made, for example, of leather, metal and / or plastic.
• Such a wristwatch is essentially composed of a dial box containing a clockwork movement, as well as a removable bracelet, the ends of which are reversibly attached to the middle of the box.
• the case is generally provided with two pairs of horns, forming connecting elements, which are respectively secured to two opposite sides of the middle part and which extend in the same direction but in opposite directions.
• the free end of each horn generally comprises a blind bore intended to receive the end of a telescopic axis, commonly called a pump, itself secured to one of the ends of the bracelet.
• this type of wristwatch has the disadvantage of not always being very comfortable to wear since it has a part, of relatively large dimensions, the structural rigidity of which does not allow the wristwatch to easily adapt to the user's wrist size.
• This rigid part corresponds to the middle part combined with two pairs of connecting horns. Of course, it is essentially these two pairs of horns, arranged in overhang relative to the middle part, which generate an excessive length in the rigid part of the wristwatch.
• the technical problem to be solved, by the object of the present invention is to propose a wristwatch comprising a middle part and a removable bracelet, each end of the bracelet being secured to the respective free ends of two connecting elements secured to the middle part, wristwatch which would make it possible to avoid the problems of the prior art by being able to adapt as best as possible to the morphology of the wearer, while offering significantly improved user comfort.
• each connecting element is mounted movable in displacement relative to the middle part, the free end of each connecting element being able to be oriented in different directions.
• the invention as defined has the advantage of reducing the dimensions of the rigid part of the wristwatch.
• the cantilever connecting elements are not here rigidly secured to the middle part. Thanks to their relative mobility, each connecting element is able to orient itself naturally in a direction substantially tangent to the curvature of the user's wrist.
• the assembly, formed by the middle part and the connecting elements, thus offers a structure which is flexible enough to be able to best fit the wrist of the user, hence a greatly improved comfort of use.
• the present invention also relates to the characteristics which will emerge during the description which follows, and which should be considered in isolation or according to all their possible technical combinations.
• FIG. 1 is a top view of a wristwatch according to the invention .
• FIG. 2 constitutes an exploded view showing in more detail the middle part and the connecting elements of the wristwatch of FIG. 1.
• FIG. 3 represents, in longitudinal section, the wristwatch of FIG. 1.
• FIG. 4 is a top view of the wristwatch of Figure 1, illustrating certain mobility of the connecting elements when the bracelet is not secured to the middle part.
• FIG. 5 constitutes a bottom view of the wristwatch shown in FIG. 4.
• FIG. 1 illustrates a wristwatch 1 essentially composed of a dial box 2 and a removable strap 3.
• the box 2 comprises a middle part 4 containing a clockwork movement here not shown for reasons of clarity.
• the ends 5, 6 of the bracelet 3 are removably attached to the middle part 4 by means notably of two pairs of connecting elements 10, 30; 20, 40 respectively arranged in opposition on the periphery 7 of said middle part 4.
• a winder 8 We also note the presence of a winder 8.
• each connecting element 10, 20, 30, 40 is mounted movable in displacement relative to the middle part 4.
• the free end 11, 21, 31, 41 of each connecting element 10 , 20, 30, 40 is .so likely to be oriented in different directions.
• each connecting element 10, 20, 30, 40 is articulated so as to be able to extend in any direction included in a cone whose apex would be located in the middle part 4.
• each connecting element 10, 20, 30, 40 comprises a spherical part 12, 22, 32, 42 forming a ball joint, as well as a radial part 13, 23, 33, 43 provided with a first assembly means 14, 24, 34, 44.
• the spherical part 12, 22, 32, 42 is shaped so as to be able to rotate in a hollow housing 15, 25, 35, 45 forming a seat.
• the first assembly means 14, 24, 34, 44 is in turn configured so as to be able to cooperate by fixing with a second assembly means 50, 60 secured to the corresponding free end 5, 6 of the bracelet 3.
• the hollow housing 15, 25, 35, 45 is constituted, on the one hand, by a substantially hemispherical cavity 16, 26,
• 37, 47 also comprises an opening 18, 28, 38, 48 allowing the passage of the radial part 13, 23, 33, 43, and consequently the mobility of the corresponding connecting element 10, 20, 30, 40.
• each clevis 17, 27, 37, 47 is secured to the middle part 4 by fixing screws not shown in the various figures, again for reasons of clarity.
• each connecting element 10, 20, 30, 40 benefits from several mobilities.
• each connecting element 10, 20, 30, 40 is able to tilt vertically over about 90 °.
• each connecting element 10, 20, 30, 40 is more precisely able to tilt vertically with respect to the plane of the wristwatch, from about 30 ° upwards as in the case of the connecting element 40, and up to about 60 ° downwards as for the element of connection 30.
• each connection element 10, 20, 30, 40 is also capable of tilting horizontally over approximately 35 °.
• each connecting element 10, 20, 30, 40 is thus able to tilt horizontally up to 5 ° inwards and 30 ° outwards, relative to a plane P which is orthogonal to the plane of the wristwatch 1 on the one hand, and orthogonal to the sagittal plane S passing through the winder on the other hand.
• This characteristic is particularly advantageous for compensating for possible assembly clearances which may exist between the first assembly means 14, 24, 34, 44 and the second associated assembly means 50, 60.
• each connecting element 10, 20, 30, 40 is furthermore able to rotate axially on itself, that is to say around the direction in which said connecting element 10, 20, 30, 40 extends.
• each first assembly means 14, 24, 34, 44 is constituted by a through bore, forming a bearing 19, 29, 39, 49, which is able to cooperate with a connecting pin 51, 61, forming a second assembly means ⁇ 50 , 60.
• Each connecting axis, 51; 61 is held in two corresponding bearings 19, 39; 29, 49 by means of two locking screws 52a, 52b; 62a, 62b, forming a stop at the respective ends of each connecting axis 51; 61.
• FIG. 5 more specifically shows the lower part of each yoke 17, 27, 37, 47. It also makes it possible to observe the presence of a bottom 9 allowing access to the interior of the box 2, from below. wristwatch 1. This bottom 9 is also fixed to the lower edge of the middle part 4 by a set of fixing screws.
