Definitions

• the present invention relates to a wrist watch with interchangeable strap.
• the invention finds a particularly advantageous application in the field of the watch industry.
• Various types of interchangeable strap wristwatches have already been proposed in the past.
• a watch is known in particular whose bracelet in two parts can be mounted and dismounted by tilting a horn allowing access to a fixing rod, integral with the watch, along which can slide in one direction or in the another each of the parts of said bracelet.
• This mode of interchangeability of the bracelet has the disadvantage of being delicate and impractical to use, which in the long term results in wear and deterioration of the horns and of the fixing rods.
• a wristwatch is also known, the bracelet of which, in a single piece, is provided with a central cutout intended to be engaged around a chimney body on the middle of the watch.
• this type of watch has the disadvantage that the bracelet can easily escape from the chimney body and detach from the middle as soon as it is no longer closed against the user's wrist.
• the technical problem to be solved by the object of the present invention is to propose a wristwatch with interchangeable bracelet, comprising a middle part comprising a chimney body, and a bracelet in one piece, provided with a central cutout intended to be engaged around said chimney body, which would ensure, in all circumstances, a positive maintenance of the bracelet on the middle of the watch, without otherwise being detrimental to the general aesthetics of the watch.
• said wristwatch comprises a cover which can be folded down on the bracelet by rotation around a hinge provided on the middle, said cover and said middle carrying closure means and means for opening the cover on the middle.
• the invention also provides that the chimney body is surmounted by a gouge, said central cutout of the bracelet being able to be engaged around said chimney body by flexible deformation in the passage of said gouge. , and vice versa.
• the bracelet is retained on the middle of the watch by the gouge which prevents any movement of involuntary withdrawal of the bracelet.
• the gouge which prevents any movement of involuntary withdrawal of the bracelet.
• This interchangeability process is therefore very easy to use and requires no complex mechanical parts, which guarantees reliability.
• the invention provides that the cutout is carried out through a central reinforcing core provided in said bracelet.
• said central reinforcing core is constituted by Kevlar (registered trademark).
• the design of the wristwatch, object of the invention is such that it completely integrates the bracelet with the aesthetics of the watch, which, in addition to its nominal function, becomes an essential element of decoration which justifies its interchangeability.
• the closure means are constituted by a notch formed in the cover, cooperating with a spring hook disposed on the middle part, while said opening means consist of a pusher of said hook -spring.
• said pusher is integrated into a crown of the watch winder.
• Figure 1 is a half side view in section of a wristwatch according to the invention.
• Figure 2a is a top view of the wristwatch of Figure 1 with the cover open.
• FIG. 2b is a top view of the wristwatch of Figure 1 with the cover closed.
• FIG. 3 is a sectional view of the winder of the wristwatch of FIG. 1.
• Figure 4a is a bottom view of the frame forming the cover of the wristwatch of Figures 1, 2a and 2b.
• Figure 4b is a side view of the frame of Figure 4a.
• Figure 5 is a schematic perspective view of the wristwatch of Figure 2a with the cover open.
• FIG. 1 shows in half-section a wristwatch with interchangeable bracelet 10 comprising a middle part 20 comprising a chimney constituted by a chimney body 21, for example cylindrical, surmounted by a circular gouge 22 having a diameter substantially greater than that of the body 21 of chimney.
• the wristwatch of Figure 1 also includes a bracelet 10, in one piece, which can also be seen in Figures 2a, 2b and 5.
• the bracelet 10 is provided with a central cutout 11 to the dimensions of the body 21 chimney. In the case of a cylindrical chimney, the cutout 11 of the bracelet is, of course, circular with a diameter equal to that of the body 21 of the chimney.
• the bracelet 10 is thus able to be pressed against the middle part 20 by introduction of the said central cutout 11 around the chimney body 21 by flexible deformation in the passage of the said gouge 22. Due to the obstacle to withdrawal presented by the gouge 22, the bracelet 10 is held in place in the middle part 20 by the cutout 11.
• the interchangeability of the bracelet is ensured thanks to the possibility of releasing the bracelet 10 from the middle part 20 in a limited effort. reverse movement to that which allowed the introduction of the bracelet on the middle.
• the window 23 of the wristwatch of Figure 1 is preferably made of sapphire.
• the bottom 24 of the middle part 20 is a round screw bottom.
• the water resistance of the watch is guaranteed up to 3 x 105 Pa (3 atm).
• Figures 1, 2a, 2b and 5 indicate that the wristwatch of the invention further comprises a cover 30 which can be folded down on the strap 10 which, in the proposed embodiment, is a frame shown in more detail in Figures 4a and 4b, comprising an upright 31, called a closing amount, parallel to the axis of the bracelet 10, and two lateral uprights 32, 33 perpendicular to the closing amount 31 and connected to a hinge 40 arranged on the middle part 20, around which the frame-cover 30 can rotate at least 90 °.
• a cover 30 which can be folded down on the strap 10 which, in the proposed embodiment, is a frame shown in more detail in Figures 4a and 4b, comprising an upright 31, called a closing amount, parallel to the axis of the bracelet 10, and two lateral uprights 32, 33 perpendicular to the closing amount 31 and connected to a hinge 40 arranged on the middle part 20, around which the frame-cover 30 can rotate at least 90 °.
• a hinged cover in the form of a frame is in no way limiting, it could just as easily be full, for example.
• This folding cover whatever its shape, allows, on the one hand, to positively maintain the bracelet 10 on the middle part 20, and, on the other hand, to add to the aesthetics of the watch. It can be made of steel, solid gold, gold and steel, or gold set with diamonds. Similarly, the bracelet can be made of leather, gold and steel or all of gold.
• the frame 30 and the middle part 20 respectively comprise means for closing the frame of the middle part, constituted in the embodiment presented by a notch 51 made in the upright 31 for closing the frame 30, cooperating with a spring hook 52 disposed on the middle part 20.
• the closing of the frame is therefore very easily obtained by simple pressure on the frame 30 so as to elastically engage the spring hook 52 in the notch 51.
• the opening of the frame 30 is effected by the actuation of opening means constituted, for example, by a pusher 60 of the spring hook 52, integrated into the crown 71 of the watch winder 70 of the watch.
• opening means constituted, for example, by a pusher 60 of the spring hook 52, integrated into the crown 71 of the watch winder 70 of the watch.
• the pusher 60 drives a barrel 61 which comes to bear against the hook-spring 52 in order to release the latter from the notch 51, thus freeing the frame 30.
• the opening of the frame can be facilitated by the presence inside the lateral uprights 32, 33 of the frame 30, of springs 34, 35 of lamella release.
• this central reinforcement core is constituted by Kevlar (registered trademark).
