Waterproof, out-of-round watch case

The invention "relates to a waterproof, non-circular Watch case.

The production of waterproof, out-of-round watch cases are known to pose numerous difficulties in the way, since the best practices in the manufacture of round watch cases not simply transferred to the manufacture of non-round housings permit. -

The invention has a waterproof, non-circular wristwatch case With a glass rim shoulder (lunette) and a capsule fixed in it immovably and encompassing the work to the subject.

Most known watch cases of this type have the capsule the shape of a dome with a flat bottom. The outer edge of the The dome is flush with the side wall of the bezel. She's into that Embedded bezel and attached to it in such a way that a sealing ring is axially compressed, which between the upper Edge of the side wall and a rim of the glass is embedded. The outer edge of the glass itself is turned inside held the bezel. Glass edge and base caps close to this vise. 1 an annulus in which. the sealing ring lies.

This known construction of wristwatch cases has the disadvantage that the fastening means of the base cap are arranged with the bezel on the outside of the ring roughness with the seal,

109838/0580 bad

TJk is already on to hide the fasteners from sight the back of the bottom capsule has a solid false bottom, which fits the bezel inside, but the false bottom increases the thickness of the case considerably. on the other hand it does not protect the fasteners against the attack of the Moisture and against bumps. Over time, water and penetrate Dirt in the space between the bottom dome and the side wall the bezel, attack the fasteners and make it more difficult the dismantling.

In the case of the well-known non-round watch cases mentioned above, it was previously also required the tube for the elevator shaft to attach the bottom capsule. Until the wall of the sod dome the wall of the sealing space is formed, you need to practice hold this wall. So you have to be in the wall of the bezel Provide a relatively large cutout and expand it so that the bottom dome with the work and tube is inserted at an angle and can be fixed by turning, whereby the tube comes to lie in the cutout.

In addition, this construction requires effort to "lock" the winding shaft in the clockwork, because the clockwork is inserted into the bottom dome from above and the. once fixed adjusting screw is then no longer accessible from below, borrowed.

The invention solves the problem of producing a non-round watch case in which the space between the bottom capsule and dkv bezel is sealed on the outside, the tube is attached to the bezel and the fastening means of the assembled parts are protected against moisture by the fact that the fastening means for the closure are supported on the bottom dome and its Press around the bezel using a sealing ring,

The fastener and the fastening means can be seen from the rear the housing must be sealed. This feature allows a recess or opening to be made on the back of the joint.

payment card no. of the watch case according to Pig. I and Pig. 3 is a perspective view of the individual parts from which the watch case is assembled "

In the drawing, 1 is the bezel, 2 is the housing ring, 3 is a Retaining ring, 4 and 5 parts of the clasp, which are also in one piece can be and 6 the cap. The bezel 2 contains the Y / Erk 7 with the. Dial 8 which can be viewed through glass 9 can. The seal is made by three rings 10, 11 and 12 between the glass 9 and the bezel 1, the bezel 1 and the deca closure part 5 and finally between the closure part 4 and the lid 6.

The steady rest 1 comprises a pipe section 13 of square cross-section, which has a re-entrant flange 14 at the top. One of ^T 'Jti.de of Sohrstücks has a bore 15, is in the tube a sixteenth In. In two other hands, the piece of pipe 13 has abutments 17 for fastening the Uiirarra band. On the inside of the four walls there are openings for s. ~~~ 18 in the middle and near the upper edge.

The glass 9 is square. The sides are formed into a pipe section 19 mit'Plansch 2o. The sealing ring 10 lies on the surface 2o. The dial S lies entirely within the pipe section 19. ,

The Gehäusirig 2 consists of ketall. Its interior is adapted to the caliber of the movement, its exterior _profile: interior profile

the; Bezel 1. A _n its upper side, the housing ring 2 has a collar 21, which has a constant thickness over the entire circumference and follows the profile of the wall 13 of the bezel 1. The upper side of the collar 21 rests against the glass flange 2ο and presses it onto the sealing ring 10. On its lower side, the housing ring 2 has a shoulder 25 of varying width. The collar 21 sits on a ring 23 from .dem the work ring 22 protrudes inward. The ring 23 has four straight side surfaces on the outside and a hollow cone 24 on the inside. Its lower circular opening is framed by a rib 26. Because the fiippe 26 is circular, the shoulder 25 has its largest width in the corners and its smallest width in the length of the side surfaces of the ring 23.

The hip 26 extends over the lower surface of the Work, but with another version it can also be arranged so that there is no free space between the bevel of the work and the bezel is created. The inner surface of the rib 26 is threaded.

The shoulder 25 rests against the retaining ring 3, which consists of steel and is provided with flaps 27 that have been cut. The lobes 27 are slightly bent and thus secure the attachment of the housing ring 2 and the pressure on the sealing ring 10 as soon as it is screwed into the cutouts 18. The cutouts 28 are used to Use of a tool with which the ring is rotated for locking can be.

Before defining the housing ring 2 by means of the retaining ring ^{1 to} 3, it is expedient to insert the elevator shaft. The winding shaft passes through the tube 16 in the opening 29 which is provided in the side wall of the housing ring 2. By means of a screwdriver, which is inserted through the opening 30, the adjusting screw 31 can be turned and the shaft can be locked.

The retaining ring 3 is then inserted and the work 7 is thereby finally determined.

Instead of the retaining ring 3 described, you can attach ^, ^ 109839/0580

For the purpose of the housing ring 3, also use screws 32 as shown in FIG. 2. These screws are provided with a collar which surrounds them in a calf circle. The screw is screwed into the threaded hole 35 before the housing ring 2 is inserted, so that the collar 33 is located in the interior of the housing ring. With the bevel ring inserted into the bezel, the collar 33 can be pivoted into the milled recess 18 by turning the screw 32. As a result, the sealing ring 10 is put under pressure. With this form of vibration, the entire movement can be fastened before the winding shaft is locked. '

The closure part 4 is only used for centering and can also ' be in one piece with the closure part 5. The two parts can also be welded together, the square outside of the Closure part 4 lies within the bezel I, its circular one The inside of the rib 26 rests on the outside. The closure part 4 has an inwardly projecting collar 36 that extends from the hip and the thread in the interior of the rib 26 continues with one or two individual threads.

The closure part 5 overlaps the closure part 4, it has an outer rib 37 »which rests against the housing ring 2, that is to say square and also encloses the sealing ring 11.

The closure base 6 is round and has a threaded collar 38 at its top, when inserting the bottom 6 in the Closing parts 5 and 4, the collar 38 initially rotates into the Thread 36 and then into the thread ar, the inside of the rib 26 a. As a result, he first presses the sealing ring 11 together, then the sealing ring 10 and finally the one around the collar 38 put around the seal ring 12. For this purpose, the base 38 has a Edge flange 39, in the Ausseti recesses 40 for the use of a Tool are embedded. The recesses 40 correspond to the recesses 28 in the retaining ring 3, so that c; an for rotating the diode 6 and the retaining ring 3 can use the same tool.

■ As soon as the 3oden. 6 is screwed tight thanks to the locking part 5 all spaces 2.B, between the closure part 4 and the bezel 1 and between the bezel 1 and the bottom 6 through the sealing rings 11 and 12 closed watertight,

Moisture can then still between the closure parts 4 and 5 penetrate. To avoid this, it is advisable to use the To make locking parts 4 and 5 in one piece.

Thanks to the fact that the sealing ring 10 does not lie between the housing ring and the glass rim as in the known designs, but between the bezel 1 and the glass flange 20, are all spaces between the housing ring 2, the bezel 1 and the parts that make up the bottom, tightly sealed. Even the retaining ring 3 or the screws 32 are against the access of Moisture protected.

The means for fastening the movement 7 in the housing 2 are not shown. These means are usually pins which are let into the housing ring. The already mentioned fact that the case ring does not need to form a tightly closed partition wall allows these usual fastening means to be used in the watch case of the invention as well. This constitutes one of the advantages _fe Rossen having the invention. Another great advantage of the invention is the increased watertightness of the construction. Since the housing ring 2 sits firmly in the bezel I, it forms an ir.assive part, so that the glass 9 and the bezel I are completely sealed against each other, even in the event that the glass 9 has a square or rectangular shape.

Thanks to the fact that the bottom 6 is screwed into the housing 2 can be, you can seal the bottom 6 and the locking part 4.5 also well against each other, namely with the same means with which this is done with round watch cases. Finally, the closure parts 4 * 5 also work under the most favorable conditions, as they are in axial sighting through Forces are claimed, polygamy on the inner edge of their 5 ^ "109839/0580

impact. The sealing ring 11 which is axially zusamirengedrüekt, lie _f ~ t very close to the point of action of the axially acting KrLLf te. The construction also allows one of the most difficult problems encountered with square or rectangular watch cases to be solved. Until now, ir.an could not determine whether the ring between the bezel and the base was taut over its entire length. Since, in the construction of the invention, the flange 59 of the base 6 can extend as far as the tangent to the bezel, a compensation of the Konvpressionskrcfte is achieved under ideal conditions. The total height of the watch case can be kept very small.

To simplify the construction, the housing ring 2 and the closure part 4 can be made from plastic. Flat rings or so-called O-hinge can be used for the sealing rises,

In another embodiment, the !! altering 3 can through a corrugated spring washer can be replaced by spring force Jumps into the Ätisf rc sunken IS; you can also do all the other known ones Fasteners such as washers on fitting rings use.
