Definitions
- the present invention relates to a blind device mobile, especially for timepieces, according to preamble to independent claims 1, 2 and 4.
- the device comprises two lateral supports, parallel to the plane 6:00 a.m. - 12:00 p.m. and welded on the corresponding sides of a rectangular middle a timepiece, each of these supports being provided with a closed circuit groove made around the trace formed between said face of the middle part and the face inside of the support.
- the blind itself is formed tubular elements interconnected, while the ends of these elements have wires guided in the grooves, the blind being thus movable above ice.
- the means of the device allow an execution relatively flat and are designed to equip in particular a high-end wristwatch.
- the object of the invention is therefore to overcome the disadvantages mentioned above, that is, on the one hand, to obtain a sliding of the curtain which is perfect and reliable, so as to meet the most demanding requirements draconian clientele and, on the other hand, correlatively, to master this function of sliding, so that any untimely movement of the curtain is impossible.
- the blind device being, as as we said, planned more particularly for a high watch range, we can observe that the search for solutions is all the more awkward that account should be taken of specific constraints, in addition to the constraints posed by generally by miniaturization (the implementation in the same way generally encountering problems increasing according to whether the dimensions of it are more reduced).
- the first relates to the choice materials, which cannot be done arbitrarily, rules to be observed for this type of watch; the second relates to the aspect of aesthetics, since, if is essential that the operation of the device be flawless it is no less important than this function not only does not sacrifice imperatives dictated by this component, but on the contrary serves these, allowing to improve and vary the finishes, this at the best cost.
- the box 1 provided with the movable blind or curtain device flexible 2 consists of a middle part 4, a base 5 and a glass 13, these three elements housing a movement 11 at which is connected a crown 12, said device itself comprising two stretchers 3, blind shafts 21 forming the blind and linked together by links 25, bearings 24, a stop device 9 and a protective plate 6 (Fig. 1, 2 and 3).
- Each stretcher 3 is in the symmetrical form of a oblong handle with rounded ends (see Fig. 4).
- a clearance 30 is delimited by a face 301 extending in lengthwise and by two faces 302 perpendicular to it.
- Face 32 facing the inside of the middle part 4 has a guide groove 33 composed of a rectilinear portion 34 extended on both sides and other of a circular portion 35 each opening on the clearance 30.
- Each stretcher finally presents, arranged symmetrically with respect to the plane of symmetry not shown, two internal threads 37, two retaining housings 38 provided for immobilizing the stop device on which we will come back to later and two blind holes 39 for receive the ends of a bar not shown.
- the middle part 4 of generally rectangular shape (Fig. 1 and 5), has two lateral flanks 41 extending in the direction of plan 6:00 a.m. - 12:00 p.m. and two adjacent grooves 42 (see also Fig. 3), the width of which corresponds to the thickness of the stretchers 3.
- a stretcher 3 adjusts against the internal face 421 of the flank 41 and in said groove 42, the length of the recess 30 of the stretcher corresponding to that of the groove 42.
- the bottom shown only in section in Figure 3, has also a generally rectangular shape and adjusts with precision under the middle part 4, to which it is fixed by means of screws (not shown), the middle having on the face from below (not referenced) four tapping 45 (Fig. 5).
- the protection plate 6 consists of a plate rectangular whose edges, raised at 90 °, are parallel at 6:00 am - 12:00 pm and engaged in turn in two corresponding grooves 51 made on the face of below the bottom.
- the protection plate 6 is fixed to the bottom 5 in these grooves by welding or gluing.
- each circuit extends in a plan parallel to the plan 6:00 a.m. - 12:00 p.m. and envelope in some so the middle, the two portions of circular grooves 35 of stretchers 3 opening onto a groove portion straight 63 opposite and parallel to the groove 34 of the stretcher 3 and formed, on the one hand, by a flat 52 of the bottom 5 and, on the other hand, by a flat 61 and a face 62 (perpendicular to the flat 61) of the protective plate 6 (Fig. 1 and 3).
- the awning is made up of juxtaposed awning axes 21 the number of which is of course a function of their diameter and the size of the case.
- These axes 21, which are preferably attached in one piece, have a roller blind 211 each of whose two ends is extended by an axis link 212 whose length corresponds to twice the thickness of a connecting link 25 (see FIG. 3), and a rolling pin 213 whose length corresponds to the thickness of a bearing 24.
- the pins 21 are assembled between them on each side via two rows adjacent connecting links 25 arranged on the axes of link 212 and offset, according to the example, by one step one by compared to the other: the internal row of links 25 allows to form a succession of pairs of blind axes, the outer row allowing, due to this offset, to connect these pairs together. As shown in Figure 2, the two end parts of the outer row of links are completed each time with a half link made up a ring 26.
- bearing 24 made of very high hardness material and with very high self-lubricating power.
- the bearings 24 consist of rubies whose properties meet these requirements.
- the blind can thus evolve above the glass 13 (see Fig. 1), so that you can cover it or leave it totally or partially apparent, at will, the operation being facilitated by a blind button 27.
- the maximum movement is limited by a stop device 9 known, formed by a series of stop axes which are axes similar or identical to the shafts of blind 21, said stop device comprising an opening stop 202 (shown in Figure 1, although not apparent because positioned on the bottom side) and a closing stop 201, positioned on the dial side, the latter being able to cooperate with the button 27 arranged on the first blind axis of the mobile awning to allow it to be locked in the closed position.
- the stop device 9 is secured to stretchers by known means and not described, for example by engagement of the ends of an axis abutment in blind housings 38 arranged in the stretchers 3 (Fig. 3).
- the position of the blind is maintained in any position arbitrary wanted by the wearer, whatever wrist movements, thanks to a brake device 7 (Fig. 2).
- the latter comprises a tubular element 72, of same length as rollers 211, completely housing a elastic member 73 (according to the example a coil spring) and, partially, two brake pins 71 arranged on one side and other of said spring 73.
- Each brake pin 71 has a sliding pin 711 whose diameter corresponds to internal diameter of tube 72, this sliding axis being extended, on one side, by a penetrating spring axis 714 in spring 73, the latter resting on the shoulder formed by the difference in diameters of the axes 711 and 714, and, on the other side, by a connecting axis 712 and a rolling axis 713, equivalent to the connecting axes 212 and the rolling axes 213 respectively.
- This device preferably mounted on the front of the awning, that is to say near the blind axis provided with the button 27.
- the elastic member 73 acts permanently on the two brake pins 711, the latter acting at their tower on 24 A ruby bearings, which exert thus a pressure against the faces parallel to the plane 6:00 am - 12 noon of the grooves 33 of the stretchers 3.
- the characteristics of the elastic member 73 will be chosen and defined according to the desired braking force resulting from said pressure.
- the protective plate 6 can be constituted as a grid, or be openwork, so as to reproduce a logo or a name, for example the name of the manufacturer, or any other sign. It is easy to see that the vision of scrolling of the blind, i.e. rollers 211 (the case if necessary decorated with precious stones), behind the grid or openwork, produce a most refined aesthetic effect.
- the supports comprising the closed circuit groove were welded on the middle.
- the high temperature of this had the effect of softening the material and modify the geometry of the parts, resulting, as we have said in the introduction, a risk of wear, seizure or jamming of the blind.
- the supports in the form of stretchers, are reported screwed.
- they have a higher hardness, this which considerably reduces the risk of wear and increases precision, secondly, access to crimping is simplified, thanks to the possibility of disassembly, finally, the finish can be more neat.

Description
La présente invention concerne un dispositif de store
mobile, notamment pour pièce d'horlogerie, selon le
préambule des revendications indépendantes 1, 2 et 4.The present invention relates to a blind device
mobile, especially for timepieces, according to
preamble to
Un tel dispositif est décrit dans le brevet CH-649.434 de la requérante. Selon ce document, le dispositif comporte deux supports latéraux, parallèles au plan 6H00 - 12H00 et soudés sur les faces correspondantes d'une carrure rectangulaire d'une pièce d'horlogerie, chacun de ces supports étant pourvu d'une rainure en circuit fermé pratiquée autour de la trace formée entre ladite face de la carrure et la face intérieure du support. Le store lui-même est formé d'éléments tubulaires reliés entre eux, tandis que les extrémités de ces éléments comportent des fils guidés dans les rainures, le store étant ainsi déplaçable au-dessus de la glace. Les moyens du dispositif permettent une exécution relativement plate et sont prévus pour équiper notamment une montre bracelet haut de gamme.Such a device is described in patent CH-649,434 of the applicant. According to this document, the device comprises two lateral supports, parallel to the plane 6:00 a.m. - 12:00 p.m. and welded on the corresponding sides of a rectangular middle a timepiece, each of these supports being provided with a closed circuit groove made around the trace formed between said face of the middle part and the face inside of the support. The blind itself is formed tubular elements interconnected, while the ends of these elements have wires guided in the grooves, the blind being thus movable above ice. The means of the device allow an execution relatively flat and are designed to equip in particular a high-end wristwatch.
Toutefois, le store selon cette antériorité présente deux types de lacunes qui réduisent sensiblement son intérêt.However, the blind according to this prior art has two types of gaps that significantly reduce his interest.
En effet, le porteur, lorsqu'il manoeuvre le store au moyen du bouton monté sur le premier élément tubulaire pour recouvrir ou découvrir totalement ou partiellement la glace, doit déplorer les nombreux risques de coincement et de grippage du store, selon le degré de précision de l'ajustement. En tout état de cause, la fréquence de ces inconvénients se trouve rapidement amplifiée du fait d'une usure prématurée des extrémités (fils 17 précités dans CH-649.434 ou rondelles chassées sur ces fils) des éléments tubulaires et des rainures de support. Indeed, the wearer, when he operates the blind by means of the button mounted on the first tubular element for completely or partially cover or uncover the ice, must deplore the numerous risks of jamming and seizure of the blind, depending on the degree of precision of adjustment. In any event, the frequency of these disadvantages is quickly amplified due to a premature wear of the extremities (wires 17 above mentioned in CH-649.434 or washers chased on these wires) elements tubular and support grooves.
D'un autre côté, le déplacement du store dans un sens ou l'autre, suivant les mouvements du poignet, n'est pas contrôlable lorsque ledit store n'est pas verrouillé: ou bien le jeu des fils ou des rondelles dans les rainures de glissement est grand, et des déplacements non souhaités risquent de se répéter pour prendre fin lorsque le rideau coincera. Ou bien le jeu est très fin, et les déplacements du store pourront ne pas être intempestifs lors des mouvements de poignet, mais en revanche, l'on se heurtera aux conséquences d'un grippage qui s'instaurera d'autant plus vite que les éléments de glissement en contact sont en or.On the other hand, moving the blind in one direction or the other, following the movements of the wrist, is not controllable when said blind is not locked: or well the play of the wires or the washers in the grooves of slip is great, and unwanted displacements may repeat themselves to end when the curtain get stuck. Or the game is very fine, and the movements awning may not be untimely during wrist movements, but on the other hand, we will collide to the consequences of a seizure which will be established all the more faster than the sliding elements in contact are in gold.
Dans tous les cas, on constate que le fonctionnement du rideau selon l'art antérieur cité laisse à désirer.In all cases, it can be seen that the functioning of the curtain according to the cited prior art leaves something to be desired.
Aussi le but de l'invention est-il de pallier les inconvénients évoqués plus haut, c'est-à-dire, d'une part, d'obtenir un coulissement du rideau qui soit parfait et fiable, de sorte à satisfaire les exigences les plus draconiennes de la clientèle et, d'autre part, corrélativement, de maítriser cette fonction de coulissement, afin que tout déplacement intempestif du rideau soit impossible. Le dispositif de store étant, comme on l'a dit, prévu plus particulièrement pour une montre haut de gamme, on peut observer que la recherche de solutions est d'autant plus malaisée qu'il convient de tenir compte de sujétions spécifiques, outre les contraintes posées de manière générale par la miniaturisation (la mise en oeuvre d'un même moyen se heurtant en général à des problèmes croissants selon que les dimensions de celui-ci sont plus réduites). En effet, au moins deux difficultés supplémentaires apparaissent: la première porte sur le choix des matériaux, lequel ne peut se faire arbitrairement, des règles devant être respectées pour ce type de montre; la seconde porte sur le volet de l'esthétique, puisque, s'il est fondamental que le fonctionnement du dispositif soit irréprochable, il est non moins important que cette fonction, non seulement ne sacrifie pas les impératifs dictés par ce volet, mais au contraire serve ces derniers, en permettant d'améliorer et de varier les finitions, cela au meilleur coût.The object of the invention is therefore to overcome the disadvantages mentioned above, that is, on the one hand, to obtain a sliding of the curtain which is perfect and reliable, so as to meet the most demanding requirements draconian clientele and, on the other hand, correlatively, to master this function of sliding, so that any untimely movement of the curtain is impossible. The blind device being, as as we said, planned more particularly for a high watch range, we can observe that the search for solutions is all the more awkward that account should be taken of specific constraints, in addition to the constraints posed by generally by miniaturization (the implementation in the same way generally encountering problems increasing according to whether the dimensions of it are more reduced). Indeed, at least two difficulties additional appear: the first relates to the choice materials, which cannot be done arbitrarily, rules to be observed for this type of watch; the second relates to the aspect of aesthetics, since, if is essential that the operation of the device be flawless it is no less important than this function not only does not sacrifice imperatives dictated by this component, but on the contrary serves these, allowing to improve and vary the finishes, this at the best cost.

Le boítier 1 pourvu du dispositif de store mobile ou rideau
souple 2 se compose d'une carrure 4, d'un fond 5 et d'une
glace 13, ces trois éléments abritant un mouvement 11 auquel
est reliée une couronne 12, ledit dispositif comprenant lui-même
deux brancards 3, des axes de store 21 formant le store
et reliés entre eux par des maillons 25, des roulements 24,
un dispositif de butée 9 et une plaque de protection 6 (Fig.
1, 2 et 3).The
On aperçoit à l'appui des figures 1 et 5 que les brancards
3, droit et gauche, tous deux identiques, sont rapportés par
dessus la carrure et fixés à cette dernière par des vis 44.It can be seen in support of Figures 1 and 5 that the
Chaque brancard 3 se présente sous la forme symétrique d'une
poignée oblongue à bouts arrondis (cf. Fig. 4). Un
dégagement 30 est délimité par une face 301 s'étendant dans
le sens de la longueur et par deux faces 302
perpendiculaires à celle-ci. La face 32 tournée vers
l'intérieur de la carrure 4 comporte une rainure de guidage
33 composée d'une portion rectiligne 34 prolongée de part et
d'autre d'une portion circulaire 35 s'ouvrant chacune sur le
dégagement 30. Chaque brancard présente enfin, disposés
symétriquement par rapport au plan de symétrie non
représenté, deux taraudages 37, deux logements de retenue 38
prévus pour l'immobilisation du dispositif de butée sur
lequel on reviendra plus loin et deux trous borgnes 39 pour
recevoir les extrémités d'une barrette non représentée.Each
La carrure 4, de forme générale rectangulaire (Fig. 1 et 5),
présente deux flancs latéraux 41 s'étendant dans le sens du
plan 6H00 - 12H00 et deux rainures adjacentes 42 (voir aussi
Fig. 3), dont la largeur correspond à l'épaisseur des
brancards 3. Ainsi, de chaque côté de la carrure, un
brancard 3 vient s'ajuster contre la face interne 421 du
flanc 41 et dans ladite rainure 42, la longueur de
l'évidement 30 du brancard correspondant à celle de la
rainure 42. The
Le fond, représenté uniquement en coupe à la figure 3, a
également une forme générale rectangulaire et s'ajuste avec
précision sous la carrure 4, à laquelle il est fixé au moyen
de vis (non représentées), la carrure présentant sur la face
de dessous (non référencée) quatre taraudages 45 (Fig. 5).The bottom, shown only in section in Figure 3, has
also a generally rectangular shape and adjusts with
precision under the
La plaque de protection 6 est constituée d'une plaquette
rectangulaire dont les bords, relevés à 90°, sont parallèles
au plan 6H00 - 12 H00 et engagés à leur tour dans deux
rainures correspondantes 51 pratiquées sur la face de
dessous du fond. La plaque de protection 6 est fixée au fond
5 dans ces rainures par soudage ou collage.The
Grâce à cet agencement modulaire, effectué avec précision,
deux circuits fermés de guidage du store se faisant face
l'un l'autre sont constitués. Chaque circuit s'étend dans un
plan parallèle au plan 6H00 - 12H00 et enveloppe en quelque
sorte la carrure, les deux portions de rainures circulaires
35 des brancards 3 débouchant sur une portion de rainure
rectiligne 63 opposée et parallèle à la rainure 34 du
brancard 3 et formée, d'une part, par un méplat 52 du fond 5
et, d'autre part, par un méplat 61 et une face 62
(perpendiculaire au méplat 61) de la plaque de protection 6
(Fig. 1 et 3).Thanks to this modular arrangement, carried out with precision,
two closed blind guide circuits facing each other
each other are made up. Each circuit extends in a
plan parallel to the plan 6:00 a.m. - 12:00 p.m. and envelope in some
so the middle, the two portions of
Le store est composé d'axes de store 21 juxtaposés
dont le nombre est bien sûr fonction de leur diamètre et de
la dimension du boítier. Ces axes 21, qui sont de préférence
rapportés d'une seule pièce, présentent un rouleau de store
211 dont chacune des deux extrémités est prolongée d'un axe
de liaison 212 dont la longueur correspond au double de
l'épaisseur d'un maillon de liaison 25 (voir Fig. 3), et
d'un axe de roulement 213 dont la longueur correspond à
l'épaisseur d'un roulement 24. Les axes 21 sont assemblés
entre eux de chaque côté par l'intermédiaire de deux rangées
adjacentes de maillons de liaison 25 agencés sur les axes de
liaison 212 et décalées, selon l'exemple, d'un pas l'une par
rapport à l'autre: la rangée interne de maillons 25 permet
de former une succession de paires d'axes de store, la
rangée externe permettant, du fait de ce décalage, de relier
ces paires entre elles. Comme on l'aperçoit sur la figure 2,
les deux parties terminales de la rangée externe de maillons
sont complétées chaque fois d'un demi-maillon constitué
d'une bague 26.The awning is made up of juxtaposed
Enfin, sur chacun des deux axes de roulement est monté un
roulement indépendant 24 en matériau à très haute dureté et
à très haut pouvoir auto-lubrifiant. Selon la forme
d'exécution décrite, les roulements 24 sont constitués de
rubis dont les propriétés répondent à ces exigences.Finally, on each of the two rolling axes is mounted a
independent bearing 24 made of very high hardness material and
with very high self-lubricating power. According to the form
of execution described, the
Le store peut ainsi évoluer au-dessus de la glace 13 (voir
Fig. 1), de sorte à pouvoir recouvrir celle-ci ou la laisser
apparente totalement ou partiellement, à volonté, la
manoeuvre étant facilitée par un bouton de store 27. Le
déplacement maximum est limité par un dispositif de butée 9
connu, formé d'une suite d'axes de butée qui sont des axes
semblables ou identiques aux axes de store 21, ledit
dispositif de butée comportant une butée d'ouverture 202
(indiquée à la figure 1, quoique non apparente, car
positionnée du côté fond) et une butée de fermeture 201,
positionnée du côté cadran, cette dernière pouvant coopérer
avec le bouton 27 agencé sur le premier axe de store du
store mobile afin de permettre le verrouillage de ce dernier
en position de fermeture. Le dispositif de butée 9 est
solidaire des brancards selon des moyens connus et non
décrits, par exemple par engagement des extrémités d'un axe
de butée dans des logements borgnes 38 aménagés dans les
brancards 3 (Fig. 3). The blind can thus evolve above the glass 13 (see
Fig. 1), so that you can cover it or leave it
totally or partially apparent, at will, the
operation being facilitated by a
La position du store est maintenue dans toute position
arbitraire voulue par le porteur, quels que soient les
mouvements du poignet, grâce à un dispositif de frein 7
(Fig. 2). Ce dernier comprend un élément tubulaire 72, de
même longueur que les rouleaux 211, abritant totalement un
organe élastique 73 (selon l'exemple un ressort à boudin)
et, partiellement, deux axes de frein 71 disposés de part et
d'autre dudit ressort 73. Chaque axe de frein 71 présente un
axe de coulissement 711 dont le diamètre correspond au
diamètre interne du tube 72, cet axe de coulissement étant
prolongé, d'un côté, par un axe de ressort 714 pénétrant
dans le ressort 73, ce dernier prenant appui sur
l'épaulement formé par la différence de diamètres des axes
711 et 714, et, de l'autre côté, par un axe de liai-son 712
et un axe de roulement 713, équivalant aux axes de liaison
212 et aux axes de roulement 213 respectivement. Ce
dispositif est monté de préférence à l'avant du store,
c'est-à-dire à proximité de l'axe de store pourvu du bouton
27. On comprend que l'organe élastique 73 agit en permanence
sur les deux axes de frein 711, ces derniers agissant à leur
tour sur des roulements de rubis 24 A, lesquels exercent
ainsi une pression contre les faces parallèles au plan 6H00
- 12H00 des rainures 33 des brancards 3. Bien entendu, les
caractéristiques de l'organe élastique 73 seront choisies et
définies en fonction de la force de freinage souhaitée
résultant de ladite pression.The position of the blind is maintained in any position
arbitrary wanted by the wearer, whatever
wrist movements, thanks to a brake device 7
(Fig. 2). The latter comprises a
Enfin, la plaque de protection 6 peut être constituée comme
une grille, ou être ajourée, de sorte à reproduire un logo
ou une dénomination, par exemple le nom du fabricant, ou
tout autre signe. On conçoit aisément que la vision du
défilement du store, c'est-à-dire des rouleaux 211 (le cas
échéant ornés de pierres précieuses), derrière la grille ou
l'ajour, produise un effet esthétique des plus raffinés. Finally, the
Les avantages du dispositif selon l'invention, en comparaison avec l'antériorité citée, peuvent se dégager aisément:The advantages of the device according to the invention, in comparison with the cited prior art, can emerge easily:
D'abord, dans cette antériorité, les supports comportant la rainure en circuit fermé étaient soudés sur la carrure. En plus de l'imprécision du soudage, la température élevée de celui-ci avait pour effet de ramollir la matière et de modifier la géométrie des pièces, entraínant, comme on l'a dit en introduction, un risque d'usure, de grippage ou de coincement du store. A l'inverse, selon l'invention, les supports, en forme de brancards, sont rapportés vissés. De ce fait, en premier lieu, ils ont une dureté supérieure, ce qui diminue considérablement le risque d'usure et augmente la précision, en deuxième lieu, l'accès au sertissage est simplifié, grâce à la possibilité du démontage, enfin, la finition peut être plus soignée.First, in this prior art, the supports comprising the closed circuit groove were welded on the middle. In plus the imprecision of the welding, the high temperature of this had the effect of softening the material and modify the geometry of the parts, resulting, as we have said in the introduction, a risk of wear, seizure or jamming of the blind. Conversely, according to the invention, the supports, in the form of stretchers, are reported screwed. Of this fact, in the first place, they have a higher hardness, this which considerably reduces the risk of wear and increases precision, secondly, access to crimping is simplified, thanks to the possibility of disassembly, finally, the finish can be more neat.
Ensuite, les extrémités du rideau en contact avec les rainures ne sont plus en or. En effet, les rondelles cylindriques chassées sur les fils se déformaient rapidement, de sorte que le fonctionnement devenait de moins en moins satisfaisant et de plus en plus désagréable. Grâce aux roulements en rubis - le rubis se caractérisant par son grand pouvoir de glisse et sa grande résistance à l'usure - le coulissement est d'une qualité optimale et cette qualité reste constante.Then, the ends of the curtain in contact with the grooves are no longer gold. Indeed, the washers cylindrical chased on the wires were deformed quickly, so that the operation became less less satisfactory and more and more unpleasant. grace with ruby bearings - ruby characterized by its great sliding power and high resistance to wear - the sliding is of optimal quality and this quality remains constant.
Enfin, l'aménagement d'un dispositif de frein, d'autant plus nécessaire, justement, que le coulissement est de grande qualité, permet d'assurer efficacement le maintien du rideau dans toute position voulue. De surcroít, ce dispositif est intégré dans le store, si bien qu'il n'est aucunement apparent et ne nuit pas à l'esthétique de l'ensemble.Finally, the development of a brake device, all the more necessary, precisely, that the sliding is of great quality, effectively maintains the curtain in any desired position. In addition, this device is integrated in the blind, so that it is in no way apparent and does not harm the aesthetics of the whole.
