Definitions

  • the present invention relates to a self-locking expansion device for a watch, more particularly to a self locking expansion device which can for example be hidden under the back of a watchcase in a locked position.
  • Deployable closure devices are part of the prior art. Such devices are generally made up of three hinged parts, namely a central body at each end of which a shorter side part is connected. These side parts are able to be folded or pivoted back onto the outer face of the central body, and immobilized on the body by cooperating locking means provided on the body and on each side part.
  • CH 689 931 discloses a mechanism which prevent unwanted opening of said closure device.
  • the aim of the present invention is to propose a reliable self-locking expansion device for a watch, said device being originally concealed or arranged in an aesthetic manner either on the back, or front, or on the periphery of a watchcase as to improve the aesthetics of the watch.
  • This device which connects a watchcase to two ends of a strap or bracelet, comprises a first and a second deployable elements, each having one end pivotally connected, or arranged to be pivotally connected, to an end of the strap or the bracelet and another end pivotally connected directly or indirectly to the watchcase between an unlocked position and a locked position.
  • Said deployable elements are so shaped that in the locked position they are confined under the back of the watchcase, or lie either against the circumference of the watchcase, or over the front of the watchcase.
  • the deployable elements are movable between the locked and the unlocked position by turning the watchcase while the ends of the strap or bracelet move together or apart.
  • the self-locking expansion device for connecting the watchcase (1) to two ends of a strap or bracelet (2) comprises first and second deployable elements (3, 4).
  • the first and the second deployable elements (3, 4) have one end pivotally connected to a hook element (5) connected to one end of the strap or the bracelet (2) on a first and on a second axis (11, 12) and another end pivotally connected to a disc (6) fixed under the back of the watchcase (1) on a third and on a fourth axis (13,14).
  • the deployable elements (3, 4) are made up of 3 different parts (7, 8, 9) articulated to each other by hinges as to allow said elements (3, 4) to be fully deployed in the extension of the strap or bracelet (2) ( Figure 10) when the self-locking expansion device is completely unlocked.
  • the deployable elements (3, 4) are so shaped that in the locked position they are confined under the back of the watchcase (1).
  • a decorative element (10) is located in the center of the back of the watchcase (1), the contours of said decorative element (10) and of said deployable elements (3, 4) ensure that said elements (3, 4) are nested adjacent to the decorative element (10) in the locked position.
  • the deployable elements (3, 4) are movable between the locked and the unlocked position by turning the watchcase (1).
  • the watchcase (1) must be rotated 180 degrees counter clockwise in order to ensure that the elements (3, 4) are fully deployed, assuring both an easy placement of the watch on the wrist and an easy removal of the watch from the wrist.
  • These deployable elements (3, 4) are retracted and completely confined under the back of the watchcase (1), when the watchcase (1) is rotated 180 degrees clockwise in order to bring both hook elements (5), which are connected to each end of the strap or the bracelet (2), against a portion of the circumference of the watchcase (1) to ensure that the bracelet securely holds the wrist.
  • Said hook elements (5) are shaped as to rest firmly against said portion of the circumference of the watchcase (1) when the deployable elements (3, 4) are confined under the back of the watchcase (1) and to assure that said elements (3, 4) stay retracted and completely confined under the watchcase (1) even when the latter is pulled along a vertical axis as shown in Fig. 9.
  • each deployable element (3, 4) is pivotally connected to the hook element (5) about the first and the second axis (11, 12), said axes being parallel to and spaced from each other when said elements (3, 4) are confined under the back of the watchcase (1) in the locked position causing tension line holding said elements (3, 4) in a stable position.
  • deployable elements (3, 4) are rotatably deployed when the watchcase (1) is turned counter clockwise such that the third axis (13) moves below a tension line (15), while a fourth axis (14) moves above said tension line (15), the elements (3, 4) being completely deployed and stable when the first, second, third and fourth axis (11, 12, 13, 14) are parallel to each other on said tension line (9) holding deployable elements (3, 4) in the unlocked position.
  • first and the second deployable elements (3, 4) are two hook shaped plates which are nested adjacent each other in a "Yin Yang" position in the locked position.
  • An element (17) is partially covering the top of the two deployable elements (3, 4) as shown by Figure 11 to assure that said elements (3, 4) stay retracted and completely confined under the watchcase (1) even when the latter is pulled along a vertical axis as shown in Fig. 12.
  • the deployable elements (3, 4) are so shaped that in a retracted position they lie against the totality of the circumference of the watchcase (1), the extension and retraction of the deployable elements (3, 4) being realized by turning the watchcase as described in the first embodiment.
  • Each deployable element (3, 4) is made up of a first and a second part (18, 19).
  • One end of each first part (18) is pivotally connected to a lug (20) around a first vertical axis (21) ( Figure 16), the lug (20) being situated on the periphery of the watchcase (1), while the other end of said first part (18) is pivotally connected to the end of the second part (19) around a second horizontal axis (22).
  • the second part (19) of one of the two deployable elements (3, 4) comprises at least one hole (23) adjustable around at least one crown of the watch when said part (19) lies against a portion of the circumference of the watchcase (1) in the retracted position.
  • each deployable element (3, 4) rotates around the first vertical axis (21) on the lug (20) while the end of the second part (19) rotates around the second horizontal axis (22) to the other end of the first part (18).
  • the described self-locking expansion device is suitable for watches, it can be used for other applications where the invention can be contemplated without departing from the scope of the invention as defined in the appended claims.
  • it can be adapted for a belt.
