Definitions
- the present invention relates to the field of waterproof watch cases. It relates more particularly to a box provided with a rotating bezel, of the type frequently used in scuba diving watches.
- the rotating bezel provides a marker next to the hands, especially to define a maximum dive time.
- the object of the present invention is to overcome these drawbacks by providing a watch case equipped with a rotating bezel which turns smoothly and whose sealing remains good, even at high pressures.
- the invention relates to a watch case comprising a middle part, a bezel mounted mobile in rotation on the middle part and defining between them an annular chamber and a gap open towards the outside of the case, a glass mounted so waterproof on the bezel, a seal inserted between the bezel and the middle part and disposed in said chamber.
- the seal comprises:
- a compression member disposed in said chamber on the side of the gap, interposed between and cooperating with the lips to compress them respectively against the bezel and against the middle.
- the lips are connected to each other by an intermediate part. They are arranged so as to form an acute angle between them.
- the chamber is defined by side walls, upper and lower.
- the lips have, on the side of their free end, a contact surface intended to be in abutment on the side walls of the chamber, while the intermediate part is flat and follows the lower wall of the chamber. In order for watertightness to be ensured, the gap must not be closed.
- the compression member comprises an annular spring placed directly in contact with the lips.
- this spring has regular undulations, distributed on either side of a circle of diameter substantially equal to the median diameter of the chamber, the undulations being folded over by the line formed by the median circle, the angle of the fold being slightly greater than or equal to that formed by the lips.
- This spring can advantageously be made of stainless steel.
- the compression member can, moreover, comprise a positioning ring interposed between the spring and one of the walls of the chamber. It is advantageously arranged opposite the telescope and has positioning studs pressing on it so as to keep the intermediate part in abutment against a wall of the chamber.
- the invention also relates to a watch seal.
- a ring of annular shape made of a material of highly elastic deformable type, the section of which has two lips, and a compression member disposed between the lips and cooperating with them to compress them.
- the compression member comprises an annular spring placed directly in contact with the lips and a positioning ring cooperating with the spring to hold it in place.
- FIG. 1 is a simplified view in cross section of the elements of a watch case according to the invention
- FIG. 2 shows, on a larger scale, the structure presented by the box of FIG. 1 at the interface between the bezel and the middle, without the joint at a and with at b, and
- FIG. 1 there is shown, in part, a waterproof watch case 10 according to the invention, having a lower face 12, intended to be in contact with the arm of the wearer and an upper face 14 on the side of which the time display means are visible.
- This box essentially includes:
- the base 20 is fixed to the middle part 16, generally by screwing or by any means known to those skilled in the art, a seal being interposed between them.
- the middle part 16 has a structure arranged so as to ensure the mounting of a watch movement. It further comprises a flat surface 24 and a cylindrical surface 26 ensuring the positioning of a flange 28.
- the flange 28 is fixed to the middle by screws, schematically represented by an axis line 30. It ensures the positioning and the guiding of the bezel 18, thus allowing it to turn on the middle 16.
- the glass 22 can be fixed to the bezel 18 by bonding or by chasing with the interposition of a seal, or by any means known to the skilled person.
- the middle part 16 and the bezel 18 are shaped so as to define an annular chamber 36 having two side walls 36a and 36b, respectively formed by the middle part 16 and the bezel 18 , an upper wall 36c formed by the bezel 18 and a lower wall 36d essentially formed by the middle part 16.
- the chamber 36 is connected to the outside of the box 10 by a gap 40.
- the chamber 36 serves as a housing for a seal 42, comprising a ring 44 with two lips 44a, advantageously made of polyurethane of hardness on the order of 20 to 30 Shore A and a compression member 46.
- the ring 44 is annular and its section has an overall shape of U.
- the lower branch of the U constitutes an intermediate part 44b connecting the two lips 44a.
- the width of the U, at its base, is less than that of the chamber 36, while the lips 44a, constituting the lateral branches of the U, form between them an acute angle of the order of 5 ° to 15 °.
- the compression member 46 Inside the space 48 is housed the compression member 46. It consists of an annular spring 50 placed directly in contact with the lips 44a and a positioning ring 52 interposed between the spring and the upper wall 36c from room 36.
- the annular spring 50 is in the form of a strip of substantially constant width forming regular undulations arranged on either side of a circle of diameter D substantially equal to the median diameter of the chamber 36
- the spring 50 is obtained from a chemically machined stainless steel blade.
- the undulations are folded in V on either side of the line constituting the diameter D.
- the angle formed is slightly greater than that formed by the lips 44a, so that, when it is put in place, it constrains the free ends of the lips 44a against the walls 36a and 36b of the chamber. This angle is typically between 10 ° and 20 °. Its top is rounded. It follows from this conformation that the spring 50 has a high elasticity.
- the positioning ring 52 shown in FIGS. 4a and 4b, has the same median diameter as the ring 44. It is disposed in contact with the spring 50, opposite the bezel 18 and includes positioning pads 58 resting on the bezel 18 so as to maintain the spring 50 in contact with the lips.
- the pads 58 are cylindrical in shape and have a flat surface, intended to be in contact with the telescope.
- the height of the assembly formed by the ring 52 and by the studs 58 is equal to the distance separating the bezel 18 from the annular spring 50.
- the chamber 48 is connected to the external medium by the gap 40 and, thanks to the fact that the positioning pads 58 do not occupy the entire chamber 48, the latter is at the same pressure as the medium outside.
- the water then compresses the positioning ring 52 which presses on the seal 42 and strongly applies the lips 44a against the walls of the chamber 36.
- the higher the external pressure the more the lips 44a are strongly applied against the walls 36a and 36b from the bedroom. Under these conditions, the friction forces then created between the lips 44a and the watch case 10 make it impossible to rotate the telescope 18. There is therefore a diving lock, which increases safety.
- the diver breathes a gas mixture containing helium or hydrogen. These light gases can get inside the watch case. During the ascent to the surface, the external pressure can decrease more quickly than that prevailing inside the watch case. If a valve is not provided to regulate this overpressure, the glass can be expelled from its housing. With a box according to the invention, such a valve is not necessary. Indeed, thanks to the shape of the lips 44a, the gas contained inside the box 10 can escape freely.
- the watch case thus produced is perfectly waterproof when the outside pressure is higher than the inside pressure and it lets out the gas which it contains when the inside pressure is higher than the outside pressure.
- a waterproof watch case with a rotating bezel whose sealing qualities are particularly effective. Furthermore, these qualities are not to the detriment of the flexibility of operation of the rotating bezel.
- the chamber 36 could have a section other than rectangular.
- the seal could be oriented differently, with, for example, the lips in contact with the upper 36c and lower 36d walls, while the intermediate part would be in contact with the side wall 36a formed on the bezel 18.
- the means of assembling the bezel 18 on the middle 16 could also be considerably modified.
- the movable interior part could occupy a much larger space, in order to allow the display of a maximum of information and thus offer better reading conditions.
