Definitions

• the present invention relates to the field of watchmaking, more particularly to a device for attaching a bracelet to a watch.
• This solution is applicable to watches with horns and is largely inspired by the classic fixing of bracelets by means of a bar.
• This bar is integrated into the bracelet and the spring effect of the latter is replaced by the closings of the notches of the horns of the watch.
• CH 250 701 Another document, referenced under CH 250 701, describes a system very close to the previous document, that is to say that it also comprises locking means integrated into the watch horns to trap the two bars of the T which form the end of the bracelet.
• Document GB 2 264 222 describes a clasp mounted on the watch horns and composed of two parts, one rotating between the watch horns and the other rotating at the end of the first part and closing on it, creating a space between the two pieces where the bracelet fits.
• the clasp is part of the watch and cannot therefore participate in the desired aesthetic personalization.
• the "baguette” type watch includes a plate articulated on one of the ends of the watch (at 6 o'clock), so as to trap the loops at the ends of the bracelet when the plate is closed against the watch.
• the watch described has a double back, which thickens it and is only suitable if the presence of a visible joint is desired. In no case can this solution be considered universal for the purpose of easily exchanging the strap of a watch.
• the object of the present invention is to be able to have a strap attachment for a watch making it possible to obtain a continuous link between the watch case and the strap, which is easy to use and reliable.
• the object of the invention is achieved by a watch case having on its bottom at least one groove in which is housed the corresponding part of the bracelet, as well as by locking means integral with the watch case and coming seal the throat.
• the U shape of the groove plane is the preferred form of the invention (the two branches of the U ending on the outside of the housing), this plane can have different shapes, for example in the shape of a T (with the T bar which ends on the edge of the case). It is important that the bracelet has a part retained on the bottom of the watch and one or more arms for the connection between this part and the bracelet. According to a preferred form of the invention, the end of the bracelet is in the form of a loop.
• this closure is provided by a flap whose axis is at the edge of the housing. Once closed, this flap is pressed against the bottom of the watch and creates only a slight or no excess thickness. The tensile forces of the bracelet do not apply to the flap but to the edges of the groove.
• This flap comprises a clipping means which can be placed on its axis or along the "gripping" part and which ensures its maintenance in the closed position.
• Figure 1 is a bottom view of the connection device between a watch and a leather strap in its closed position
• Figure 2 is a sectional view of the connection device of Figure 1.
• the strap 2 (in our example, a leather strap) is terminated by a loop 20, 21.
• This loop is housed in a groove 11 formed directly in the back of the watch 1.
• This loop is locked by a flap 3 secured to the watch and whose axis 12 is located inside the strap buckle when the latter is in place.
• the closing of the shutter 3 encloses the external part of the loop 21 in the groove 1 1.
• a closing pad 13 facilitates the grip by the nail of the shutter 3 for easy opening.
• Figure 2 is a section along line AA as shown in Figure 1. It shows in detail the connection between strap 2 and watch 1.
• the leather 23 of strap 2 is mounted in a first part 24 of the loop and is held in a conventional manner, for example curved around the axis 22 and then sewn.
• This first part 24 of the loop 20, 21 is extended by two arms 20 at its ends then is closed by a bar 21. It is the latter which is housed in the groove 1 1 of the bottom of the watch 1 and comes to bear on the outer face 10 of this groove. Thus the tensile forces of the bracelet are completely distributed over the back of the watch.
• An example of means for clipping the shutter 3 could be between the edge of the inner face 14 of the groove and a corresponding boss on the shutter 3 (not shown). Although locked by the clips described above, the position of the flap 3 under the watch keeps it naturally closed and forces the user to turn it over to access the interchangeability mechanism.
• Figures 1 and 2 are shown with a leather strap, other types of bracelets are also suitable.
• the part 24 of the loop 20, 21 of the bracelet can be completed by a decorative element to link it visually with the watch case.
