Description

Boite. Dans les couronnes et poussoirs -etanches de montres, 1e paquetage, en matike 6läs- tique, est d'habitude log & , completement en- toure, de Sorte qu'il agit par compression Sur la pike qu'il enserre. Cette maniere de faire, vu les faibles dimensions du paquetage an- nulaire, presente 1'inconvenient d'exiger une trog grande precision de son trou par rap- port ä la piece qu'il enserre une,difference de quelques centiemes, en plus ou en moins, suffit pour qu'üne couronne, par exemple, tourne trog librement ou trop difficilement, Sur 1e canon ou tube de la boite. Il s'ensuit que 1'etancheit6 risque de ne plus exister ou que la couronne reste bloquee Sur 1e canon ä la fin du remontage de la montre, ce qui pro- cure 1e grave defaut du rebattement du ba- lancier. En outre, si la matiere est dejä com- prim6e par un couvercle, visse ou ajuste ä force, il est tres difficile, pour ne pas dire impossible, d'utiliser celui-ei pour augmen- ter 1e degrä d'.etancheite .du @dispositif en mo- difiant 1e trou du paquetage par krasement. La pr'esente invention a pour but de sup- primer Ges inconvenients. Elle a pour objet une boite, principalement, mais non exclusive- ment, de montre possedant au moins un or- gane de manoruvre qui traverse un organe de guidage, 1'un de Ges organes presentant une noyure fermee par un couvercle et dans la- quelle est loge ün paquetage annulaire elas- ti:que d'encombrement cylindrique. Cette boite est caracterisee en ce qu'au moins une Partie .de l'une au moins des deux surfaces du paquetage, pourtour cylindrique et base adjacente au fond de la noyure, est jointe, de fagon kanche ä. la surface correspondante de cette noyure, et en ce que, entre au moin@ une Partie de l'une au moins des trois sur- faces limitant 1e volume d'encombrement du paquetage, ä savoir 1e pourtour et les deux bases, et Gelle, en regard, -d'une des pieces de 1'organe dans lequel 1e paquetage est en ferm & , est reserve un espace suffisant pour permettre au paquetage de s'kendre libre- ment. Le dessin ei-annexe represente, ä eitre d'exemples, huit formen d'exkution de 1'ob- jet de la presente Invention et deux variantes. Box. In waterproof watch crowns and pushers, the package, made of elastic material, is usually housed and completely surrounded, so that it acts by compression on the pike it encloses. This way of doing things, given the small dimensions of the annular package, has the disadvantage of requiring a very high precision of its hole in relation to the piece it encloses, a difference of a few hundredths, in addition or in less, is enough for a crown, for example, to turn trog freely or too difficultly, On the first barrel or tube of the box. It follows that there is a risk that the water resistance no longer exists or that the crown remains blocked on the barrel at the end of the winding of the watch, which leads to the serious defect of the swinging of the balance wheel. Furthermore, if the material is already compressed by a cover, screwed or adjusted by force, it is very difficult, if not impossible, to use the latter to increase the degree of watertightness of the @device by modifying the 1st hole of the package by krasement. The present invention aims to eliminate these disadvantages. Its subject is a box, mainly, but not exclusively, for a watch having at least one operating member which passes through a guide member, one of these members having a recess closed by a cover and in the what is lodged ün elastic annular package: that of cylindrical size. This box is characterized in that at least a Part .de at least one of the two surfaces of the package, cylindrical periphery and base adjacent to the bottom of the core, is attached, so kanche ä. the corresponding surface of this core, and in that between at least a part of at least one of the three surfaces limiting the bulk volume of the package, namely the periphery and the two bases, and Gelle, opposite one of the parts of the body in which the package is closed, sufficient space is reserved to allow the package to extend freely. The appended drawing represents, by way of example, eight embodiments of the object of the present invention and two variants.

Les fig. 1, 5, 8, 9 et 10 sont cha.cune une coupe axiale dann laquelle 1'organe de ma- noeuvre est une couronne de remontoir et 1'or- gane de guidage, 1e tobe solidaire de 1a boite. Dann tour Ges exemples, Ges organes sont re- present6s coaxiaux et non assembles; 1e tobe est brise et la fig. 5 est une demi-coupe. Figs. 1, 5, 8, 9 and 10 are each an axial section in which the maneuvering member is a winding crown and the guide member is the tube integral with the case. In all the examples, the organs are represented coaxial and not assembled; 1st tobe is broken and fig. 5 is a half cut.

La fig. 2 est une vue en plan Tune pi@ce de la fig. 1. Les fig. 3 et 4 sont des coupes axiales de deux variantes d'execution de la fig. 1. fig. 2 is a plan view Tune pi@ce of FIG. 1. Figs. 3 and 4 are axial sections of two execution variants of FIG. 1.

Les fig. 6 et 7 sont des coupes axiales des pieces de la troisieme forme d'execution, dann laquelle 1'organe de manceuvre est un poussoir d'actionnement d'un mecanisme de chronographe avec son tobe, aussi s#pare, qui est 1'organe de guidage. Figs. 6 and 7 are axial sections of the parts of the third form of execution, in which the maneuvering organ is a pusher for actuating a chronograph mechanism with its tube, also separate, which is the organ guidance.

Dann toutes les formen d'exkution du dessin et les variantes, Beul 1e tobe, qui doit etre solidaire de la boite et sert de support ä la couronne ou au poussoir, est represente. In all the forms of execution of the design and the variants, Beul the first tube, which must be integral with the case and serves as a support for the crown or the pusher, is represented.

Dans ce ca.s, 1a, ba.se 6' du paquetage est serree contre 1a zone 6 du fand de la noyure par la zone exterieure 9' de la rondelle 9, poussk par 1e couvercle 8, et 1e paquetage pänetre evidem- ment un peu Jans les creusures 7 et 10; c'est cette derniere creusure, semblable ä Gelle 7 du fond de la noyure qui eree 1a zone 9' de la rondelle. Ce sont Ges rainures ou degage- ments eirc.ulaires qui permettent de laisser libre en hauteur la plus Brande Partie du pa- quetage; celui-ei est monte dann la couronne avec son trou 11 plus Petit que 1e tobe 12 qu'il doit enserrer de faVon kanche et son diametre extericur 13 plus Petit que celui 14 de la noyure 4. Le tobe 12 montre en poin- tille dann la couronne, doit etre fixe de fa- qon etanche dann la bo%te qui n'est pas re- presentk. Pour clue 1e paquetage soit bieu RTI ID="0002.0274" WI="9" HE="4" LX="1119" LY="626"> place, c'est-ä-dire exactement centre par rap- port au canon 2 de la couronne, an intereale entre Ges deux pieces Pendant 1e montage im tobe dopt 1e diametre et 1e trou correspon- dent respectivement au trou du paquetage et au eanon de 1a couronne; ainsi, il est auto- matiquement centr@ meine si son pourtour n'est pas concentrique au trou. Dann cet exemple, 1e paquetage ast Bone assemble dann 1'organe de commande, la eouronne, de ma- niere que son pourtour soit entierement libre et ses deux bases partielleinent; an n'utilise donc ainsi pour sa fixation qu'une petite Par tie de sa surface, de maniere a 1e laisser aussi libre que possible dann 1'organe et qu'il puisse agir nur la pike qu'il enserre .tont dif- feremment que d'habitude. Comme an peut alors mieux employer les proprietes Masti- ques de la matiere, il est necessaire d'a,ug- menter fortement la difference entre 1e dia- metre du trou du paquetage et eelui de 1'or- gane de guidage ou tobe 12. 0n obtient de ce fait une frietion toute autre, plus douce et c.ollant moins, entre Ges Pements et leur fa- brication en est grandement facilitee tout en realisant une etancheite beaucoup plus du rable. Il est important de faire remarquer, dune Part, qu'avec cette disposihon le pa- quetage est monte fini et que 1'operation dif- ficile de rectifier son trou est exclue et, Tau tre Part, qu'on peut aisement augmenter 1e degre d'i;ta.ncheite du couple, s'il y a lieu, en vissant 1e couverele; celui-ei sera facilement eommande, salis 1'aide d'un outil spkial, puisque 1e paquetage est peu eomprime et nur une Partie seulement. Le couvercle 8 de cette forme d'exkution est montre vu de des- Solls, en. fig. 2, avec une entaille 15 formant Dann 1a First form of execution of fig. 1, the crown 1 door, screwed in its barrel 2, the crown stem 3 of a winding stem in two sections, of which that a, c- couple to the movement is not represented. In a recess 4 of the crown, the package 5 is tightly sealed, for example in the material known under the commercial designation of plexigum, by pressing it, just the necessary quantity, against an area 6 of the bottom of the recess. which is limited by a concentric clearance or recess 7; This result is obtained with precision by screwing the lid 8 which acts through the intermediary of the washer 9, devices protected by Swiss patents Nos. 209888 and 2'16198. In this case, the base 6' of the package is clamped against the zone 6 of the core fand by the outer zone 9' of the washer 9, pushed by the cover 8, and the package obviously enters. a little Jans hollows 7 and 10; it is this last hollow, similar to Gelle 7 of the bottom of the recess which forms the zone 9' of the washer. These are the grooves or circular clearances which make it possible to leave free in height the most Brande Part of the package; this is mounted in the crown with its hole 11 smaller than the tube 12 which it must enclose in a kanche fashion and its external diameter 13 smaller than that 14 of the recess 4. The tube 12 shows a dotted line in the the crown, must be fixed watertight in the box which is not shown. For clue the 1st package is well RTI ID="0002.0274" WI="9" HE="4" LX="1119" LY="626"> place, that is to say exactly centered with respect to the barrel 2 of the crown, an intereal between the two parts During the assembly im tobe dopt the diameter and the 1st hole correspond respectively to the hole of the package and to the eanon of the crown; thus, it is automatically centered if its perimeter is not concentric with the hole. In this example, the package ast Bone is assembled in the control device, the crown, so that its perimeter is completely free and its two bases are partially indented; an therefore only uses for its fixation a small part of its surface, so as to leave it as free as possible in the organ and so that it can act on the pike which it encloses. than usual. As one can then make better use of the mastic properties of the material, it is necessary to greatly increase the difference between the diameter of the hole in the package and that of the guide member or tube 12. 0n thereby obtains a completely different friction, softer and less sticky, between the garments and their manufacture is greatly facilitated while achieving a much more durable seal. It is important to point out, on the one hand, that with this arrangement the package is assembled finished and that the difficult operation of rectifying its hole is excluded and, on the other hand, that one can easily increase the degree tightness of the couple, if necessary, by screwing the cover; this one will be easily ordered, soiled with the help of a special tool, since the package is not very compressed and covers only one part. The lid 8 of this form of execution is shown seen from des-Solls, in. fig. 2, with a notch 15 forming

une languette @elastique 16 qui, un peu d6cen trAe, permet d'obtenir une friction du cou vercle dans la Partie filetee de la noyure de la couronne, pour 1'empecher de se d6visser trop facilement; une encoche 17 permet de 1e commander en rotation. Les fonds des creusures 7 et 10@ sont paralleles entre eux mais, 1'un ou 1'autre ou tous les deux, pour raient evidemment etre coniques; en outre, au lieu d'etre situes dans les pieces rigides composant 1a couronne, un de ces .degage ments au meins peut etre prevu dans 1e pa quetage, surtout si celui-ei est execute par moulage. Avec une telle disposition, la mise en place de la couronne sur 1e tube de la boite est facile parce que 1e paquetage a toute libert6 pour penetrer et se leger dans 1'espace limit6 par les fonds des creusures 7 et 10, respectivement de la couronne et de la rondelle. Il en est tout autrement lorsque 1e paquetage est comprime dans la noyure de la couronne: il se forme alors, 1e plus sou vent, un mince bourrelet annulaire dans 1e treu du couvercle qui procure une resistance appreciable et nuisible lors du montage de la couronne sur 1e tube de la boite et pre sente 1e d'efaut d'etre finalement arrache, ce qui abime 1e paquetage; en outre, 1a Pres sion agissant sur .ce dernier 1e fait glisser, la longue, sur 1e fond de 1a noyure de 1.a couronne, ce qui a pour effet de reduire, dans 1e voisinage, 1e treu du paquetage d'o il en r-6sulte une augmentation exageree du frottement sur 1e tube, lorsqu'on fait tour ner la couronne, pouvant amener la d6t6rio ration du paquetage et, ce qui est .grave egalement, la difficulte de remettre celle-ei en Position de remontage, apr s une mise 1'heure de la montre, parce que 1'extremite retrecie du treu du paquetage, en agissant sur celle arrondie du tube, tend 6loigner la couronne de la boite. an elastic tongue 16 which, slightly off-center, allows friction to be obtained from the neck in the threaded part of the crown recess, to prevent it from unscrewing too easily; a notch 17 makes it possible to order it in rotation. The bottoms of the recesses 7 and 10@ are parallel to each other but one or the other or both could obviously be conical; moreover, instead of being located in the rigid parts composing the crown, one of these .degage ments at least can be provided in the first package, especially if the latter is executed by molding. With such an arrangement, the installation of the crown on the tube of the box is easy because the package has complete freedom to penetrate and lighten up in the space limited by the bottoms of the recesses 7 and 10, respectively of the crown. and washer. It is quite different when the package is compressed in the core of the crown: it then forms, most often, a thin annular bead in the hole of the cover which provides an appreciable and harmful resistance when mounting the crown on the tube of the box and presents the first fault of being finally torn off, which damages the first package; in addition, the pressure acting on the latter causes it to slide, the long one, on the bottom of the groove of the crown, which has the effect of reducing, in the vicinity, the hole of the package from which it this results in an exaggerated increase in friction on the tube, when the crown is rotated, which can lead to damage to the package and, which is also serious, the difficulty of returning it to the winding position, after setting the time of the watch, because the narrowed end of the treu of the package, by acting on the rounded end of the tube, tends to move the crown away from the case.

Dans la variante de la fig. 3, 1e couvercle 18, qui est ajuste librement dans la noyure 1.9 de la couronne 1, y est serti, apres qu'on a fait penetrer, comme il convient pour r6a liser 1'etancheite, une zone @6 du fond de la noyure 19 dann la basa 6' du paquetage 5, In the variant of fig. 3, the first cover 18, which is fitted freely in the recess 1.9 of the crown 1, is crimped there, after having penetrated, as is appropriate to achieve sealing, a zone @6 of the bottom of the recess 19 in the 6' base of package 5,

ceci sous 1'influence dune forte, un poids par exemple, fixee par des essais. Cette zone 6 du fond de 1a noyure est delimitee par une creu sure 7, semblable celle de la fig. 1. Le pa quetage 6tant aussi monte avec un fort jeu dans la noyure, il a une liberte analogue ce lui de 1'exemple precedent. Le .canon 2, de la couronne est prolonge par une petite noyure 20 dans laquelle penetre 1e tube 12, montre en pointille. this under the influence of a strong force, a weight for example, fixed by tests. This zone 6 of the bottom of the recess is delimited by a sour hollow 7, similar to that of FIG. 1. Since the package is also mounted with a lot of play in the core, it has a freedom similar to that of the previous example. The barrel 2 of the crown is extended by a small recess 20 into which the first tube 12 penetrates, shown in dotted lines.

Dans la variante de la fig. 4, 1e couver cle 21 est 6vide et prMente, -concentrique ment sa noyure 2.2., une creusure 23 lais sant libre, en hauteur, la Partie centrale du paquetage; ce dernier Fait joint en s'appli quant contre 1e fond 6 de 1a noyure de la couronne 1, sous la poussee de la zone 22' du couvercle, chasse foree. La precision de ce chassage est obtenue en repassant 1'etampe 1e pourtour du couvercle et la pa roi de 1a noyure de la couronne, tous les deux cylindriques; c'est pour cela que cette paroi est interrompue par une rainure concentri que 24. La liberte relative du paquetage est obtenue ici, gr te au degagement 2-3 du cou verele et au fait qu'il est plus Petit que la noyure de ce dernier. In the variant of fig. 4, the first key lid 21 is hollow and presents, -concentrically its recess 2.2., a hollow 23 leaving free, in height, the central part of the package; the latter Done joined by applying against the first bottom 6 of the recess of the crown 1, under the thrust of the area 22' of the lid, drilled flush. The precision of this driving in is obtained by ironing the stamp around the periphery of the lid and the wall of the crown recess, both cylindrical; this is why this wall is interrupted by a concentrated groove 24. The relative freedom of the package is obtained here, thanks to the 2-3 clearance of the verele neck and the fact that it is smaller than the core of this last.

Dans la deuxieme forme d'execution de la fig. 5", la noyure de la couronne 1 est ana logue celle de la fig. 1 et presente aussi une creusure 7; pour faciliter 1e taraudage de la paroi 25, an y a pratique une rainure 25'. La Base du paquetage- 5 est jointe en. la collant la zone 6 du fond de la noyure; lors de cette operation, il penetrera un peu de tolle dann la creusure 7 et dans 1'espace compris entre 1e paquetage et 1a noyure dopt 1e diametre est reduit, en cet endroh, pour former un epaulement 26 destin retenir 1e ressort-bague 27, de sectiorl rectangulaire, qui entoure 1e paquetage .dans @sa Partie me diane, de fapon exercer sur lui une action , radiale contribuant 1@etancheite avec 1e tube 12. L'epaulement 26 empeche le,deplacement du ressort 27 lorsqu'on met la couronne sur 1e tube de la boite. Pour prot6ger et fixer la Position de ce ressort-bague sur 1e paquetage, s il pourrait eire enrob6 dune mince enveloppe elastique en 1e collant ä ce dernier, par exemple. Dans cette forme d'exkution, 1e couverele 8, par 1'intermediaire de la ron- delle 9, est 1ä surtout pour retenir 1e paque- tage, lorsqu'on met la couronne en Position de mise 'a 1'heure. Le ressort-bague 27 pour- rait etre remplace par un ressort ä boudin ä fil de seetion ronde ou rectangulaire, ayant plusieurs spires. In the second embodiment of FIG. 5", the recess of the crown 1 is analogous to that of FIG. 1 and also has a recess 7; to facilitate the first tapping of the wall 25, there is practice a groove 25'. The Base of the package- 5 is joined by gluing it to zone 6 of the bottom of the recess: during this operation, a little iron will penetrate into the hollow 7 and into the space between the package and the recess adopted, the diameter is reduced at this point. , to form a shoulder 26 destined to retain the first ring spring 27, of rectangular section, which surrounds the first package .in @ its middle part, so as to exert on it a radial action contributing 1 @ tightness with the first tube 12. shoulder 26 prevents the displacement of the spring 27 when the crown is placed on the tube of the box. To protect and fix the position of this spring-ring on the package, if it could be coated with a thin elastic envelope by sticking it to the In this form of execution, the cover 8, through the intermediary of the washer 9, is there above all to retain the package, when the crown is put in the positioning position. 1 hour. Ring spring 27 could be replaced by a wire coil spring of round or rectangular shape, having several turns.

Les fig. 6 et 7 montrent separement les organes de manceuvre 28 et de guidage 29, d'un poussoir de chronographe; dans ce Gas, c'est 1'organe de guidage ou piece tubulaire 29 qui regoit 1e paquetage, dann sa Partie de plus Brand diametre, dans laquelle il est joint de fagon 6tanche par un couverele 30 serti. Ce paquetage, la noyure qui 1e contient et 1e couverele sont semblables ä ceux de la va- riante de 1a fig. 3.. Figs. 6 and 7 show separately the bodies for maneuvering 28 and guiding 29, of a chronograph pusher; in this gas, it is the guide member or tubular piece 29 which receives the first package, in its part of greater diameter, in which it is joined in a sealed fashion by a cover 30 crimped. This package, the core which contains it and the cover are similar to those of the variant of fig. 3..

Dans la forme d'exkution de la fig. 8, la noyure de la couronne 1 presente une creu- sure 7, et un degagement 31 coaxial 5, la noyure, qui limitent les deux zones 6 et 32 auxquelles sont colles la base et 1e pourtour du paquetage 5. Ce degagement 31 permet de coller une Partie de la hauteur du paque- tage seulement et de lui procurer 1'espaee nkessaire pour qu'il puisse fonetionner libre- ment lorsqu'il enserre 1e tube 12. Pour par- faire cette liberte, le couverele 33' est fixe ä la eouronne en laissant un Petit espace jus- qu'ä la base du paquetage; ce dernier est donc libre partout an il n'est pas coll@. In the execution form of fig. 8, the recess of the crown 1 has a recess 7, and a recess 31 coaxial 5, the recess, which limit the two zones 6 and 32 to which the base and the first periphery of the package 5 are glued. This recess 31 makes it possible to only part of the height of the package and to provide it with the necessary space so that it can function freely when it encloses the tube 12. To perfect this freedom, the cover 33' is fixed to the crown leaving a small gap to the base of the package; the latter is therefore free everywhere an it is not coll@.

Dans la forme d'exkution de la fig. 9; 1e pourtour 34 du paquetage 5 est colte ä la paroi de la noyure, de la couronne 1, en lais- sant un espace 35 entre Bon Fond 36 et la Base du paquetage; en outre,le couverele 37 est chasse, da-ns ladite noyure, en mbnabeant un intervalle 3-8 jusqu'ä Pautre Base du pa- quetage. Ce dernier a ainsi toute liberte en hauteur; bien entendu, il pourrait encore etre joint de facon kanche ä la couronne en 1e forgant un peu dans sa noyure qui serait exe- cut6e, de pr6ference, de maniere que Beule une Partie de la hauteur du paquetage soit ajustee. Enfin, dans la forme d'exeeution de la fig. 10, 1e paquetage 5 est represente joint sans Pression ä une rondelle intermediaire 39, en matiere elastique egalement, ajustee dans la noyure 4 de la couronne 1 et, de prefe- rence, collee au fond de ladite noyure, sem- blable ä Gelle de la fig. 1; cette rondelle a Bon trou plus Brand que celui du paquetage, pour procurer ainsi l'espace 40 entre la Partie centrale de la base de celui-ei et 1e fond de la noyure. Le joint etanche entre le paque- tage et cette rondelle s'obtiendra avec une tres faible Pression realisee au moyen du couverele 8, agissant par l'intermediaire de la zone 9' de la rondelle creusee 9, ceci du fait que ce contact s'effectue entre des surfaces en mauere elastique. Dans cet exemple, 1e couverele possede seulement 1'entaille 15, formant la languette elastique 16, de celui represente en fig. 2. C'est par 1e fond de cette entaille qu'on pourra le monter et 1e faire tourner au moyen de la saillie d'un outil perce dans lequel penetrera, pour 1e guider, la tige de remontoir ou 1e canon de la cou- ronne, lorsqu'il s'agira de renforeer 1'effet d'etancheite, an 1e fera tourner tout simple- ment avec un tournevis. In the execution form of fig. 9; the periphery 34 of the package 5 is glued to the wall of the core, of the crown 1, leaving a space 35 between Bon Fond 36 and the Base of the package; moreover, cover 37 is forced into said core by a gap of 3-8 to the other base of the package. The latter thus has complete freedom in height; of course, it could still be joined in a kanche way to the crown by forging it a little in its recess which would be executed, preferably, in such a way that only a part of the height of the package is adjusted. Finally, in the embodiment of FIG. 10, the package 5 is shown joined without pressure to an intermediate washer 39, also made of elastic material, fitted in the core 4 of the crown 1 and, preferably, glued to the bottom of the said core, similar to Gelle of fig. 1; this washer has a hole larger than that of the package, thereby providing space 40 between the central portion of the base thereof and the bottom of the core. The tight seal between the package and this washer will be obtained with a very low pressure achieved by means of the lid 8, acting through the intermediary of the zone 9' of the hollow washer 9, this because this contact is carried out between elastic mauer surfaces. In this example, the cover has only the notch 15, forming the elastic tongue 16, of that represented in FIG. 2. It is through the bottom of this notch that it can be mounted and rotated by means of the projection of a drilled tool into which the winding stem or the barrel of the crown will penetrate to guide it. rone, when it is a question of reinforcing the sealing effect, an 1e will simply turn it with a screwdriver.

Par les dimensions du paquetage, sa hau- teur et 1'epaisseur de la rondelle, il est evi- demment possible de modifier un peu la puis- sance avec laquelle il enserre de faqon etan- che la pike accoupl,ee. En outre, lorsque, pour de petites couronnes ou poussoirs, Ges dimensions deviennent un peu faibles, an pourra diminuer 1'espace entre 1e pourtour du paquetage et 1a noyure qui 1e contient jus- qu'ä Wen plus laisser meme; de cette fa@on, ce pourtour vient buter plus ou moins forte- ment contre la noyure, sous 1'effet de la pike qu'il enserre, et contribue ainsi ä 1'etancheite du cou.ple, par reaction. By the dimensions of the package, its height and the thickness of the washer, it is obviously possible to slightly modify the power with which it tightly encloses the coupled pike. Furthermore, when, for small crowns or pushpieces, the dimensions become a little small, the space between the periphery of the package and the core which contains it can be reduced until we are no longer left even; in this way, this periphery abuts more or less strongly against the core, under the effect of the pike that it encloses, and thus contributes to the tightness of the couple, by reaction.

Le paquetage qui, dans tous les exemples dkrits, est cylindrique est donc facile ä, exe- cuter par decoupage ou par moulage; en me- nageant une Borge en sa Partie mediane, cela permettrait d'obtenir plus facilement, en vis- sant 1e couvercle, un trou qui se retrecit en s'olivant, du fait que 1e paquetage cede mieux à sa partie faible pour se bomber à l'opposé. Cette gorge pourrait être aussi obtenue par la réunion de trois rondelles dont le diamètre de celle du milieu serait un peu plus petit; il conviendrait alors bien que cette rondelle soit entourée par la bague-ressort de la fig. 5. Ce ressort pourrait aussi être de section ronde et avoir plus d'un tour par exemple. The package which, in all the examples described, is cylindrical is therefore easy to produce by cutting or by molding; by arranging a Borge in its middle part, it would make it possible to obtain more easily, by screwing the cover, a hole which shrinks as it opens, because the package yields better to its weak part to bulge at the opposite. This groove could also be obtained by the union of three washers whose diameter of that of the middle would be a little smaller; it would then be appropriate for this washer to be surrounded by the spring ring of FIG. 5. This spring could also be of round section and have more than one turn, for example.

Le collage du paquetage peut se faire aisément, sans outillage particulier, lorsque le paquetage est figé dans la noyure de l'or gane le contenant au moyen d'un couvercle qui donne, en même temps, la pression néces saire. The gluing of the package can be done easily, without special tools, when the package is fixed in the core of the organ containing it by means of a cover which gives, at the same time, the necessary pressure.

Une petite rainure ou une petite saillie circulaire, que posséderait le fond de la noyure contre lequel une zone du paquetage est jointe de façon étanche, contribuerait à cette étanchéité. Le vide compris entre le pourtour du paquetage et les pièces de l'or gane dans lequel il est logé pourrait rece voir une matière appropriée, de la graisse consistante par exemple, augmentant l'étan chéité. A small groove or a small circular projection, which would have the bottom of the core against which an area of the package is sealed, would contribute to this sealing. The space between the circumference of the package and the parts of the organ in which it is housed could receive a suitable material, consistent grease for example, increasing the seal.

On utilisera, pour le paquetage, une ma tière possédant le mieux les qualités sui vantes: élastique dans le sens de la résistance des matériaux avec un faible module d'élas ticité pour ne pas avoir besoin de trop serrer les tolérances de fabrication, suffisamment plastique pour que ses surfaces puissent être jointes de façon étanche, sous l'effet -de la pression élastique, à des surfaces métalliques rigides même si celles-ci ne sont pas parfaite ment lisses, stable dans le temps, non corro sive et inaltérable. We will use, for the packing, a material having the best the following qualities: elastic in the sense of the resistance of the materials with a low modulus of elasticity so as not to need to tighten the manufacturing tolerances too much, sufficiently plastic so that its surfaces can be joined in a sealed manner, under the effect of elastic pressure, to rigid metal surfaces even if these are not perfectly smooth, stable over time, non-corrosive and unalterable.

Claims

CLAIM: Box, mainly, but not exclusively, for a watch, having at least one maneuvering member which passes through a guide member, one of these members having a recess closed by a cover and in which is housed an annular package rubber band of cylindrical size, characterized in # that at least a part of at least one of the two surfaces of the package - periphery -cylindrical and base - adjacent to the bottom of the recess, is joined, so sealed, to the corresponding surface of this core, and in that, between at least a part of at least one of the three surfaces limiting the bulk volume of the package, namely the periphery and the two bases, and that , in, look, one of the parts of the body in which the package is closed, is reserved sufficient space to allow the package -to extend freely ment. SUB-CLAIMS 1. Box according to claim, characterized in that the aforementioned space is reserved between at least one of the bases of the package and the surface of the piece facing it, and extends circularly over the major part of the radius - of this base.

2. Box according to claim, characterized in that the package mounted in the recess has its finished hole, smaller than the cylindrical element of the member that it must enclose and its smaller outer diameter than that of said drowning.

3,. Box according to claim, characterized in that the package is joined in a leaktight fashion to the bottom of the core by means of a washer, also made of elastic material, the hole of which is larger than that of the package.

4. Box according to claim da and sub-claims 2 and 3 @, characterized in that the package is applied against the ron delle sealing, at least indirectly, by means of a cover penetrating into the recess.

5. Box according to claim and under claim 2, characterized in that the package is applied sealingly against the bottom of the core by means of a vercle neck penetrating therein and which acts at least indirectly.

6. Box according to claim, characterized in that the package is joined in a sealed manner to the two surfaces of the core by gluing an -exterior zone of one of its bases and its periphery, on part of its height, surfaces which are delimited respectively by circular and concentric recesses of the core, a space being reserved between its other base and the piece opposite.

7. Box according to claim, characterized in that the package is joined in a sealed manner by sticking its periphery to the par- king, cylindrical of the core; a space being reserved between each of its bases and respectively the bottom of the core and the cover.

8. Box according to claim, characterized in that the lid is forced into the recess, to seal.

9. Box according to claim, characterized in that the tightness of the package with the core is ensured by the cover which is screwed and acts on it by means of a thin washer made of rigid material.

10. Box according to claim, characterized in that a peripheral zone of a base of the package is glued to the bottom of the core.

11. Box according to claim and sub-claim 2, characterized in that the package is surrounded, at least over part of its height, by a spring.
