Definitions

  • the present disclosure relates generally to the field of watchmaking, and in particular the present disclosure relates to a flexible watch strap in one piece provided with devices for attaching to a watch case.
  • the present disclosure also relates to a removable attachment device relative to a watch case.
  • a watch strap whether flexible or formed of metal links, comprises two strands, each connected by one end to the watch case. Their second end cooperates or is intended to cooperate with a clasp buckle, of the pin or folding buckle type.
  • An aim of the present invention is to respond to the drawbacks of the prior art mentioned above and in particular to provide a strap to be attached to a watch case, which makes it possible to attach a single-strand flexible strap, called a flexible strand by following, even if the watch case is not suitable for a flexible one-piece strand.
  • Another object of the invention is to provide a device for attaching a bracelet to a watch case, which is simple to manufacture and to assemble.
  • the passage opening is a slit, preferably closed, but it is also possible to provide an open U-shaped slit.
  • the flexible strand is a single-strand bracelet, or in one piece, comprising at least one pin buckle.
  • the flexible strand is a strap of the “NATO” type, for example made of fiber, and typically has a width of 20 mm, and a length greater than or equal to 250 mm.
  • each fastening device has a length at least greater than 18 mm, and preferably at least greater than 20 mm.
  • a width of the passage opening is greater than or equal to 1.5 mm.
  • At least one passage opening is a slot formed by a second bar removably mounted on one of the fastening devices. It is thus possible to alternately fix a bracelet in two parts or two strands.
  • the first attachment portion is designed to be attached to one of the first bars which has a free length of less than 12 mm.
  • the first attachment portion is designed to be attached to one of the first bars which may have a particular diameter, or a particular shape, such as for example a curved shape.
  • the flexible strand is a fabric strap, preferably of the NATO type.
  • the flexible strand can therefore be made of fibers, such as plastic fibers made of a polymer such as polyamide, or with natural fibers of plant origin, such as cotton for example.
  • fibers such as plastic fibers made of a polymer such as polyamide, or with natural fibers of plant origin, such as cotton for example.
  • an elastomer such as natural or synthetic rubber.
  • a length of the passage opening is at least greater than 18 mm, and preferably at least greater than 20 mm, to allow a flexible NATO type strand to slide into the passage opening.
  • a width of the passage opening is greater than 1.5 mm.
  • the passage opening is a slot formed by a second bar removably mounted on the fastening device.
  • the first attachment portion is designed to be attached to a first bar having a free length of less than 12 mm.
  • the attachment device comprises elastic return means, arranged to return the locking member (the second half-link) to the locking position.
  • the attachment device comprises a first and a second half-link, which makes it possible to limit the number of components. As a result, manufacture and assembly are simplified.
  • first half-link and the second half-link when coupled form a complete link.
  • the first half-link and the second half-link coupled together form the carcass of a complete link, that is to say the framework which allows the complete link to be hooked to two components of the watch to be linked together (the rest of the bracelet, to be linked to the watch case).
  • the first half-link (or the second half-link) cannot perform this linking function on its own, it is necessary that the two half-links are coupled to each other to constitute a complete link capable of connecting them together.
  • two components of the watch (the rest of the bracelet, to be connected to the watch case).
  • a complete link (formed by the first half-link and the second half-link) is typically a component of a chain or a link, and which comprises a first end arranged to be articulated with a first adjacent member to be connected (the watch case), and a second end arranged to be articulated with a second adjacent member to be connected (the bracelet, which may include other links or a ribbon, or a strap, etc.).
  • the complete link formed by the first half-link and the second half-link has two ends each intended to be articulated with an adjacent member to be connected.
  • the first end of the complete link is formed by the first attachment portion, and the second end of the complete link is formed by the second attachment portion.
  • the first attachment portion can be opened or closed by the second half-link.
  • the first attachment portion is provided on the first half-link
  • the second half-link is coupled to the first half-link to close and open the first attachment portion.
  • the feature of removability (disassembly) of the fastening device on the watch case is provided by the second half-link, and not by the hooking portion of the watch case (the first bar of the watch case, which can however also be anchored in a removable manner on the lugs of the watch case for example).
  • the sliding connection of the second half-link on the first half-link provides improved maneuverability at the level of the attachment device itself, which is removable from the watch case independently of the attachment portion (the first bar) .
  • the first half-link comprises the second attachment portion.
  • the figure 1 shows in perspective a flexible strand 200 equipped with a removable attachment device.
  • a device for interchangeability of the bracelet on a watch case is illustrated, and consists of a first half-link 10 and a second half-link 20.
  • the flexible strand 200 is typically a monofilament fabric strap (in one piece) and of sufficient length to attach a watch to the wrist of a user.
  • Such a flexible strand can be called a NATO strap or a G10 strap and generally has a width of 20 mm, and a length of at least 250 mm, for example 280 mm.
  • Such a flexible strand 200 therefore requires that the watch case have an inter-lug distance compatible with the above dimensions, in particular because of the width of the flexible strand 200.
  • the attachment device makes it possible to removably attach the flexible strand 200 to a watch which is not initially intended for this function, for example with a distance between lugs less than 20 mm, or an insufficient width of the slot between the first bars of the watch and the case.
  • the figure 2 shows in perspective an exploded view from above of the fastening device of the figure 1 , which comprises the first half-link 10, the second half-link 20, a second bar 30, a closing plate 40, and two springs 50.
  • the first half-link 10 supports the second bar 30 via horns 14 and comprises a spout 11 opposite the second bar 30, as well as two first lateral slide surfaces 13.
  • the beak 11 forms a groove, visible in a side view, arranged to receive a first bar 101 of a watch case 100 as will be shown in figure 8 .
  • the figure 3 which shows in perspective an exploded view from below of the fastening device of the figure 1 , shows that the first half-link 10 also includes a slot 12 which can receive the closing plate 40 visible on the figures 2 and 3 .
  • the second half-link 20 also visible figures 2 and 3 comprises a clasp portion 21, a notch 24 opposite to the clasp portion 21, a support wall 22 and two second side rails 23.
  • the second slide surfaces 23 are arranged to cooperate with the first slide bearing surfaces 13, so that the second half-link 20 is arranged to be mounted on the first half-link 10 in a sliding connection in order to form a locking member.
  • the term sliding link should be understood in the broad sense, and other means of cooperation in translation of the two half-links can be envisaged.
  • the closure plate 40 is a wall designed to be housed in the slot 12 of the first half-link 10, so as to trap the springs 50 between the closure plate 40 and the supporting wall 22 of the second half-link 20 as show it figure 4 . Provision can be made for the closure plate 40, once mounted in the slot 12, to remain in position due to a tight fitting provided for, or by virtue of an elastic locking element (clipping), or a locking by a pin or a screw, or a dot of glue, or even a solder.
  • clipping an elastic locking element
  • the second half-link 20 is movable in translation with respect to the first half-link 10 and can occupy a locking position ( figure 4 ) or an open position ( figure 5 ).
  • the second half-link 20 forming a locking member, is pushed by the springs 50 into a locking position.
  • the clasp portion 21 of the second half-link 20 is opposite and above the spout 11 of the first half-link 10, so that the groove formed by the spout 11 is closed.
  • the fastening device is thus locked on the watch case if a first bar 101 of the watch case is engaged in the groove formed by the spout 11.
  • the figure 5 shows the cross section of the fastening device of the figure 1 , with the second half-link 20 forming the locking member in an open position. Indeed, under the action of a user, the second half-link 20 has been pushed to the left, compressing the springs 50, which allows the clasp portion 21 to release the groove formed by the spout 11. Accordingly, the user can attach or detach the fastening device from the watch case.
  • the second half-link 20 is in one piece and / or in one piece, and can be ordered directly by the user. There is no need to provide an attached control button, which provides a fastening device with few components, and few assembly operations. In other words, the second half-link 20 is intended to be actuated directly by the user, without intermediate parts, to unlock the fastening device.
  • the figure 6 shows a top view of the fastening device, where it can be seen that the second fastening portion B comprises the slot 60 formed by the second bar 30 and the rest of the fastening device (in particular the horns 14 of the first half link 10 and the notch 24 of the second half-link 20).
  • the slot 60 (hatched to be clearly visible) forms a loop and its dimensions are designed to easily receive the flexible strand 200.
  • the width of the slot 60 is typically greater than or equal to 20 mm, and its width is greater than or equal to 1.5 mm.
  • the width of the first attachment portion A is markedly less than the width of the slot 60, so that the attachment device shown makes it possible to attach a flexible strand 200 of the NATO type. for example on a watch case which cannot itself form a loop for such a type of flexible strand, without deforming or bending the strand.
  • the figure 7 represents a section of the top view of the figure 6 , where we see the springs 50 mounted between the closing plate 40 and the supporting wall 22. Note that the closing plate 40 and the supporting wall 22 both include blind holes 41 and 220 respectively, so that the overall size is reduced and assembly facilitated because the blind holes pre-position the springs 50.
  • first slide bearing surfaces 13 are completely nested with the second slide bearing surfaces 23 when the second half-link 20 is in the locking position.
  • first half-link 10 has a first width L10 and the second half-link 20 has a second similar width L20, with for example: 0.8 ⁇ L 10 ⁇ L 20 ⁇ 1.2 ⁇ L 10
  • the first half-link 10 and the second half-link 20 both have dimensions which allow them to be manufactured by traditional manufacturing technologies.
  • the figure 8 shows a watch case 100 comprising two first bars 101, with an attachment device coupled to each of them via the first attachment portion A, and a flexible strand 200 (single strand) is attached to the two attachment devices via their second attachment portion B.
  • the second half-link 20 of each attachment device forms a locking member that is easy to actuate for the user, since it is accessible directly from above.
  • the two attachment devices provide the possibility of attaching this. type of single-strand strap on the watch case.
  • first bars 101 of the watch case 100 it is possible to envisage designing the first attachment portion A to be compatible with any other attachment interface of the watch case 100: a tenon, or a comb for example ...
  • an interchangeability device on the watch case is not limiting, and other opening - closing systems for attaching - detaching the attachment devices on the watch case can be provided. .
