Definitions
- the present invention relates to a rotating bezel for a watch case, in particular a rotating bezel provided with a locking mechanism to prevent rotation of the bezel in one of the two directions of rotation.
- a frequent application of rotating glasses consists in indicating a residual diving time.
- the telescope is in this case provided with a graduation corresponding to minutes. traversed by the minute hand of the watch; colored segments on the bezel are sometimes used which allow the diver, for example, to quickly detect that it is time to go back up when the hand points to a range of red color.
- Locking means are often provided to prevent rotation of the telescope in one of the two directions of rotation, generally clockwise.
- the bezel can however pivot in the other direction. It sometimes happens during a diving session that the telescope accidentally turns without the diver realizing it. Even if the allowed rotation always goes in the direction of a decrease in the displayed immersion time, this results in insecurity for the diver who cannot entirely trust the position of the telescope. In an extreme case, a succession of shocks or involuntary contacts could cause the telescope to rotate by more than 180 °, which could bring the telescope back into a position indicating a longer residual immersion time than it is in reality.
- CH503306 describes a watch case comprising a bezel comprising a locking mechanism to prevent its rotation.
- the telescope is mounted on three pistons actuated by springs pushing the telescope up (glass side).
- a radial toothing on the middle prevents any rotation of the bezel in this position.
- it is necessary to press it against the action of the springs in order to release it from this toothing and thus allow its rotation.
- this glasses is not yet entirely satisfactory. It is indeed relatively easy to rotate it by pressing on any portion of the telescope while simultaneously exerting a tangential force.
- the angular position of the bezel can be changed when the watch case rubs against a surface, for example against a rock or against the suit of the diver.
- An object of the present invention is therefore to propose a rotating bezel system which offers greater security than the systems of the prior art.
- a rotating bezel comprising a locking mechanism, for example a notching system, to prevent rotation of the bezel in at least one of the two directions of rotation.
- the locking mechanism can only be released by a voluntary action of the user of the telescope by pressing on a determined angular segment of the telescope.
- the telescope comprises at least a first angular segment and at least a second angular segment, and the locking mechanism can be released only by pressing on the first angular segments, but not by pressing on the second angular segments.
- the telescope comprises alternating first angular segments and second angular segments.
- the angular position of the telescope can then only be modified by pressing simultaneously on a predetermined minimum number of first segments, for example by simultaneously pressing on at least two first distinct segments.
- the present invention thus also relates to a rotating bezel for a watch case comprising a first locking mechanism for, 0 • ⁇ . block the rotation of the telescope in au; less. a first direction of,, rotation, in which the first locking mechanism can be released so as to allow the rotation of the bezel in the first direction of rotation only by acting simultaneously on at least two distinct points of said rotating bezel.
- the second angular segments on which a pressure has no effect are in a preferred variant salient with respect to the first angular segments. This further reduces the risk of accidentally releasing the bezel during an impact or friction of the watch with an external object.
- Figure 1 a perspective view from above of a watch case provided with a bezel according to the invention.
- Figure 2 a perspective view from below of a watch case provided with a bezel according to the invention.
- the watch case of the invention comprises a middle part 23 shown in a simplified manner and a bezel 2 consisting of two elements 20, 21.
- the first element 21 comprises a set of six first angular ring segments 211, separated from each other by intervals 210.
- the first mechanism for locking the telescope counterclockwise can be released by pressing simultaneously on at least two segments 211.
- the underside of the first element 21 comprises a serrated notch 212.
- This notch is intended to cooperate with a set of elastic stops 220 (third stop, or pawl) on a ring 22 described below to prevent rotation of the telescope only clockwise.
- a set of elastic stops 220 third stop, or pawl
- the second element 20 of the bezel 2 comprises six second angular segments 200 arranged on a ring 201.
- the shape and the arrangement of the second angular segments 200 correspond to those of the intervals 210 of the first element 21, so that the second element 20 can s '' fit practically without play over the first.
- the second segments 200 are however substantially higher than the first segments 211.
- the assembled bezel 2 thus comprises an alternation of six first segments 211 and six second segments 200 shorter and projecting.
- the second segments 200 further comprise teeth 203, visible more particularly in FIG. 2, directed radially outward and constituting second stops cooperating with a radial toothing 221 (first stop) described below to prevent rotation of the telescope 2 counterclockwise.
- each segment 200 comprises a tooth 203.
- the number of teeth 203 is limited to three and certain segments 200 are devoid of teeth.
- the bezel further comprises a ring 22 of metal or synthetic material participating in the locking mechanism in the first and in the second direction of rotation.
- the ring 22 is provided with feet 222 engaged in openings not shown in the middle part 23, so as to prevent the rotation of the ring 22 relative to the middle part.
- the ring is free to move vertically over several millimeters between the middle part 23 and the bezel 2; one or more springs, not shown, between the middle part and the ring 22 make it possible to push the latter against the bezel 2 in the rest position.
- the vertical elastic force is exerted by portions 223 of the ring 22 in elastic abutment against the middle part 23.
- the internal radial toothing 221 on the ring 22 constitutes a: r first stop.
- the teeth 203 of the second element 20 are engaged in the toothing 221, so that the rotation of this bezel is blocked.
- the first angular segments 211 it is possible, by acting against the action of the aforementioned spring, to push the ring 22 against the middle part 23, so as to release the toothing 221 from the teeth 203. It is then possible to make rotate the telescope 2 counterclockwise only, the teeth 212 remaining in contact with the stops 220 of the ring 22 to prevent rotation in the clockwise direction.
- the ring 22 thus fulfills three distinct functions:
- First stop function 221 to prevent any rotation of the telescope 2 when the ring 22 is raised to the upper position
- Second stop 220 cooperating with the teeth 212 of the bezel to prevent rotation of the bezel clockwise even when the user presses on the portions of the bezel allowing it to be released. Rotating the bezel counterclockwise is possible.
- Spring function for raising the ring 22 and the first element 21 in the raised position above the middle.
- these three functions are carried out using a single piece 22 of synthetic or possibly metallic material. It may be preferable in other alternative embodiments of the invention to carry out these three functions using two or even three separate parts. For example, in order to limit wear on the toothing 221, it is possible to make it using a metal piece. A synthetic ring 220 can then be molded over this toothing to perform the two other functions above.
- the elastic force raising the ring 22 and the bezel can also be exerted by one or more separate springs, for example a metallic corrugated spring.
- the ratchet function (teeth 220) can also be achieved by a metal and / or synthetic part different from that used for the first stop and / or, for the spring.
- the clearance between the ring 22 and the middle part 23 as well as the clearance between the two elements 20, 21 are chosen to be sufficiently small, so that the first element 21 can only move along a perfectly vertical axis.
- By pressing on a single first angular segment 211 one tends to tilt the plane of the first element 21, which blocks its movement. In order to move the first element 21, it is therefore necessary to press simultaneously on at least two first distinct segments 211. This characteristic offers additional security, since it is thus impossible to release the telescope 2 by acting on a single first angular segment 21 1.
- the bezel 2 is fixed to the middle part 23 in a conventional manner using a not shown spring slid in an internal groove 204 of the second element 20 and in an external groove 230 of the middle 23.
- the box spring is dodecagonal, an angle of the spring being engaged in each second segment 204. The box spring therefore holds the second element 20 by above the middle part 23, the first spectacle element 21 and the ring 22 being held in sandwich between the second element 20 and the middle part 23.
- the pan spring is open and therefore occupies an angular segment of less than 360. At least one of the two ends of the pan spring is then folded outwards so as to cooperate with two lateral faces of the segments 200 and thus preventing rotation of the spring with respect to the second element 20. It goes without saying that the spring with sides can pivot around the middle part 23 when the bezel 2 is actuated.
- the illustrated embodiment includes an alternation of six first segments 211 and six second segments 200.
- Other arrangements are however possible, involving: a different number of first and / or second segments.
- the number of first segments can be different from the number of second segments.
- the marking and the color of the different segments can be chosen so as to leave no doubt as to the operations to be carried out to operate the telescope.
- the first counterclockwise rotation blocking mechanism and the second clockwise rotation blocking mechanism use, in the preferred example described, a common ring 22 comprising both first stops 221 and thirds stops 220. It would however be possible to arrange these stops on separate elements.
