Definitions
- the subject of the present invention is a lockable waterproof pusher especially for a watch case that ensures normal sealing operating pressure of approximately 10 bars in the active position and a super-tightness of around 100 bars in the locked rest position.
- Another object of the present invention is to provide a sealed pusher in which the sealing members, generally one or more seals, are located in such a way that they protect not only the inside of the box from shows but also the mechanism of the pusher itself.
- Yet another object of the present invention is to provide a pusher waterproof, especially for watch cases, which is simple, robust, has a reduced number of parts and requires no maintenance.
- a waterproof pusher for document diving watch CH 624 259 which comprises on the one hand a tube screwed into the watch case and on the other hand a pusher head sliding in this tube tightly using a seal, this pusher head being intended to be integrally connected to a thrust member acting on a mechanism.
- the pusher head has a annular recess in which is housed an axially sliding bushing but not angularly on the outside of the tube and cooperating with the pusher head by a screw thread.
- a second seal surrounding the pusher head core can be forcibly applied against the head tube and core when the socket is moved by a rotation of the head towards the tube.
- This device has drawbacks, the main ones being require several moving parts and several seals at several levels of the device, these seals do not protect the pusher mechanism itself since water or dust can get between the head and the socket of the mechanism.
- a rotation of the head is necessary, rotation which also causes a corresponding rotation of the thrust member. This can lead to wear of the watch mechanism actuated by the pusher, which is undesirable.
- the present invention relates to a lockable waterproof pusher allowing achieve the goals set out above and obviate the disadvantages of the devices existing.
- the lockable waterproof pusher according to the present invention is distinguished by the characteristics set out in claim 1. Other characteristics of this lockable waterproof pusher are listed in the claims dependent.
- the attached drawing illustrates schematically and by way of example a shape execution of the lockable waterproof pusher according to the invention.
- Figure 1 is an axial section of the pusher in the locked position.
- Figure 2 is an axial section of the pusher in the service position unlocked but in its inactive position for which it does not operate the mechanism he controls.
- Figure 3 is an axial section of the pusher in the service position unlocked but in its active position activating the mechanism it controls.
- Figure 4 is a sectional view of the pusher along line A-A of the figure 1.
- the pusher waterproof lockable intended to equip in particular a watch case comprises a pusher tube 1 comprising a lower male part of small diameter 2 and an upper male part 3 of larger diameter, separated by a shoulder 4.
- the lower male part 2 is intended to be driven into a hole in the middle of a watch case.
- the upper male part 3 has on its peripheral surface exterior a groove 5 intended to receive one or two seals 6.
- This upper male part 3 has a bore 7 having a shoulder internal 8, circular bore extending into the lower male part 2 and ending with a hexagonal portion 9.
- the pusher further comprises a tubular pusher body 10 having an internal annular rib 11 forming a stop.
- Upper body 11 has a thread 12 on the internal wall of the body while the part bottom of this body has a recess whose inner wall has a cylindrical part 13 and a conical part 14 both cooperating with the joints 6.
- the distance separating the lower face of the rib 11 from the front face lower part of the body 3 corresponds to the distance separating the shoulder 4 from the tube 1 of its upper front face. So when this underside of the rib 11 abuts against the upper front face of the tube 1, the front annular face of the body 10 is located substantially in the same plane as the shoulder 4 of the tube 1.
- the pusher also has a pusher axis 15 whose end upper comprises a head 16 provided on its periphery with a cooperating thread with the internal thread 12 of the body 10 and on its underside with a circular groove 17.
- the lower part of this pusher axis 15 has an end part hexagon socket engaged in the lower end 9 hexagon socket of the tube 1.
- the lower end of the pusher axis 15 has an axial thread 18 intended to receive a retaining screw 19.
- a return spring 20 is arranged around the pusher axis 15 and takes support on the one hand at the bottom of the groove 17 of the head 16 of this pusher axis and on the other hand on the internal shoulder 8 of the pusher tube and tends to move away axially the head 16 of the pusher axis 15 of the pusher tube 1.
- the head of the retaining screw 19 abuts against the lower front face of the tube 1 limits the axial travel of the possible movement of the pusher axis 15 relative to the tube 1 defining the inactive position of the pusher (fig. 1 and 2).
- the pusher further comprises a pusher cap 21 driven out and glued on the upper part of the pusher body 10 practically unremovable.
- the pusher is illustrated in the locked position, the cap 21 and the body 10 forming a whole is screwed onto the head 16 of the pusher axis.
- This axis cannot rotate in push tube 1 due to the six-part sides of its end cooperating with the hexagonal bore of the tube.
- the head of the retaining screw 19 abuts against the free front face of the pusher tube 1.
- the user unscrews the cap assembly 21 and body 10.
- This assembly moves relative to the tube 1 and to the axis of pusher 15 until the head 16 of this pusher axis 15 abuts against the internal rib 11 of the body.
- the seals 6 In this position illustrated in FIG. 2, the seals 6 always seal although they are less compressed since they do not are more in contact with the conical part 14 of the body 10. This seal reduced operating, is of the order of 10 bars.
- the user can activate the push-button function by pressing on the cover 21 causing the axial displacement of the pusher axis 15 relative to the pusher tube 1 against the action of the spring reminder 20 to arrive in the active position illustrated in Figure 3 where the screw holding 16 activates a mechanism.
- This active axial position of the pusher is limited by the contact of the internal rib 11 of the body 10 with the surface top of pusher tube 1.
- This lockable waterproof pusher is particularly advantageous in that it is very simple and robust, that the number of its parts is reduced and its use is simple and reliable.
- this pusher is that the or the seals are placed in one place between the pusher tube 1 and the body of pusher 10. This seal is therefore upstream of the pusher mechanism itself in relation to the flow of water or dust that could penetrate between the tube and body.
- the thread between the head 16 of the pusher axis and the body 10 as well as the return spring 20 are also protected from contamination external, which is not the case in the previous pushers.
- Another advantage of this pusher is that the pusher rod 15 cannot move angularly relative to the pusher tube 1, this which reduces the wear that the mechanism controlled by such a pusher can undergo.
- the axial distance x by which the cap 21 and the body 10 of the pusher relative to the head 16 of the pusher rod 15 is determined to so that it is equal to or greater than the active stroke y of the pusher to perform its function but also equal to or less than the distance z separating the lower shoulder 4 of the tube 1 of the pusher of the lower side wall of the groove 5 receiving the joint (s) 6. In this way these joints 6 are always in active position ensuring sealing at least 10 bar operating about.
- the upper part of the body 10, necessarily open for mounting the push pin 15, could be closed by a screw cap or any other closure member in place of the cap 21.
Abstract
Description
La présente invention a pour objet un poussoir étanche blocable notamment pour boíte de montre qui permette d'assurer une étanchéité normale de fonctionnement d'environ 10 bars en position active et une super-étanchéité de l'ordre de 100 bars en position de repos bloquée.The subject of the present invention is a lockable waterproof pusher especially for a watch case that ensures normal sealing operating pressure of approximately 10 bars in the active position and a super-tightness of around 100 bars in the locked rest position.
Un autre but de la présente invention est de réaliser un poussoir étanche dans lequel les organes d'étanchéités, généralement un ou plusieurs joints, sont situés de telle façon qu'ils protègent non seulement l'intérieur de la boíte de montre mais encore le mécanisme du poussoir lui-même.Another object of the present invention is to provide a sealed pusher in which the sealing members, generally one or more seals, are located in such a way that they protect not only the inside of the box from shows but also the mechanism of the pusher itself.
Un autre but encore de la présente invention est de réaliser un poussoir étanche, notamment pour boíte de montre, qui soit simple, robuste, comporte un nombre de pièces réduits et ne nécessite aucun entretien.Yet another object of the present invention is to provide a pusher waterproof, especially for watch cases, which is simple, robust, has a reduced number of parts and requires no maintenance.
On connaít un poussoir étanche pour montre de plongée du document CH 624 259 qui comporte d'une part un tube vissé dans la boíte de montre et d'autre part une tête de poussoir coulissant dans ce tube de façon étanche à l'aide d'un joint, cette tête de poussoir étant destinée à être reliée solidairement à un organe de poussée agissant sur un mécanisme. La tête de poussoir comporte un évidement annulaire dans lequel est logée une douille coulissant axialement mais non angulairement sur l'extérieur du tube et coopérant avec la tête de poussoir par un pas de vis. Un second joint entourant le noyau de la tête de poussoir peut être appliqué à force contre le tube et le noyau de la tête lorsque la douille est déplacée par une rotation de la tête en direction du tube.We know a waterproof pusher for document diving watch CH 624 259 which comprises on the one hand a tube screwed into the watch case and on the other hand a pusher head sliding in this tube tightly using a seal, this pusher head being intended to be integrally connected to a thrust member acting on a mechanism. The pusher head has a annular recess in which is housed an axially sliding bushing but not angularly on the outside of the tube and cooperating with the pusher head by a screw thread. A second seal surrounding the pusher head core can be forcibly applied against the head tube and core when the socket is moved by a rotation of the head towards the tube.
Ce dispositif présente des inconvénients dont les principaux sont de nécessiter plusieurs pièces mobiles et plusieurs joints à plusieurs niveaux du dispositif, ces joints ne protégeant pas le mécanisme de poussoir lui-même puisque l'eau ou la poussière peuvent s'introduire entre la tête et la douille du mécanisme. De plus, pour passer de la position de service à la position bloquée du poussoir, une rotation de la tête est nécessaire, rotation qui entraíne également une rotation correspondante de l'organe de poussée. Ceci peut amener une usure du mécanisme de la montre actionné par le poussoir, ce qui est indésirable.This device has drawbacks, the main ones being require several moving parts and several seals at several levels of the device, these seals do not protect the pusher mechanism itself since water or dust can get between the head and the socket of the mechanism. In addition, to move from the service position to the locked position of the pusher, a rotation of the head is necessary, rotation which also causes a corresponding rotation of the thrust member. This can lead to wear of the watch mechanism actuated by the pusher, which is undesirable.
La présente invention a pour objet un poussoir étanche blocable permettant d'atteindre les buts énoncés plus haut et d'obvier aux inconvénients des dispositifs existants.The present invention relates to a lockable waterproof pusher allowing achieve the goals set out above and obviate the disadvantages of the devices existing.
Le poussoir étanche blocable selon la présente invention se distingue par
les caractéristiques énoncées dans la revendication 1. D'autres caractéristiques
de ce poussoir étanche blocable sont énumérées dans les revendications
dépendantes.The lockable waterproof pusher according to the present invention is distinguished by
the characteristics set out in
Le dessin annexé illustre schématiquement et à titre d'exemple une forme d'exécution du poussoir étanche blocable selon l'invention.The attached drawing illustrates schematically and by way of example a shape execution of the lockable waterproof pusher according to the invention.
La figure 1 est une coupe axiale du poussoir en position bloquée.Figure 1 is an axial section of the pusher in the locked position.
La figure 2 est une coupe axiale du poussoir en position de service débloquée mais dans sa position inactive pour laquelle il n'actionne pas le mécanisme qu'il commande.Figure 2 is an axial section of the pusher in the service position unlocked but in its inactive position for which it does not operate the mechanism he controls.
La figure 3 est une coupe axiale du poussoir en position de service débloquée mais dans sa position active actionnant le mécanisme qu'il commande.Figure 3 is an axial section of the pusher in the service position unlocked but in its active position activating the mechanism it controls.
La figure 4 est une vue en coupe du poussoir suivant la ligne A-A de la figure 1.Figure 4 is a sectional view of the pusher along line A-A of the figure 1.
Dans la forme d'exécution illustrée à titre d'exemple au dessin, le poussoir
étanche blocable destiné à équiper notamment une boíte de montre comporte un
tube de poussoir 1 comportant une partie mâle inférieure de faible diamètre 2 et
une partie mâle supérieure 3 de plus grand diamètre, séparées par un épaulement
4. La partie mâle inférieure 2 est destinée à être chassée dans un perçage de la
carrure d'une boíte de montre.In the embodiment illustrated by way of example in the drawing, the pusher
waterproof lockable intended to equip in particular a watch case comprises a
La partie mâle supérieure 3 comporte sur sa surface périphérique
extérieure une gorge 5 destinée à recevoir un ou deux joints d'étanchéité 6. Cette
partie mâle supérieure 3 comporte un alésage 7 comportant un épaulement
interne 8, alésage circulaire se prolongeant dans la partie mâle inférieure 2 et se
terminant par une portion hexagonale 9.The
Le poussoir comporte encore un corps de poussoir tubulaire 10 présentant
une nervure annulaire interne 11 formant une butée. La partie supérieure du corps
11 comporte un filetage 12 sur la paroi interne du corps tandis que la partie
inférieure de ce corps comporte un évidement dont la paroi interne comporte une
partie cylindrique 13 et une partie conique 14 toutes deux coopérants avec les
joints 6. La distance séparant la face inférieure de la nervure 11 de la face frontale
inférieure du corps 3 correspond à la distance séparant l'épaulement 4 du tube 1
de sa face frontale supérieure. Ainsi, lorsque cette face inférieure de la nervure 11
bute contre la face supérieure frontale du tube 1, la face annulaire frontale du
corps 10 est située sensiblement dans le même plan que l'épaulement 4 du tube
1.The pusher further comprises a
Le poussoir comporte encore un axe de poussoir 15 dont l'extrémité
supérieure comporte une tête 16 munie sur sa périphérie d'un filetage coopérant
avec le taraudage 12 du corps 10 et sur sa face inférieure d'une gorge circulaire
17. La partie inférieure de cet axe de poussoir 15 comporte une partie terminale
six pans mâle engagée dans l'extrémité inférieure 9 six pans femelle du tube 1.
Ces deux pièces, l'axe 15 et le tube 1, peuvent donc coulisser axialement l'un par
rapport à l'autre, mais toute rotation entre ces deux pièces est interdite.The pusher also has a
L'extrémité inférieure de l'axe de poussoir 15 comporte un taraudage axial
18 destiné à recevoir une vis de retenue 19.The lower end of the
Un ressort de rappel 20 est disposé autour de l'axe de poussoir 15 et prend
appuis d'une part au fond de la gorge 17 de la tête 16 de cet axe de poussoir et
d'autre part sur l'épaulement interne 8 du tube de poussoir et tend à éloigner
axialement la tête 16 de l'axe de poussoir 15 du tube de poussoir 1. La tête de la
vis de retenue 19 venant buter contre la face frontale inférieure du tube 1 limite la
course axiale du déplacement possible de l'axe de poussoir 15 par rapport au tube
1 définissant la position inactive du poussoir (fig. 1 et 2). A
Le poussoir comporte encore une coiffe de poussoir 21 chassée et collée
sur la partie supérieure du corps de poussoir 10 de façon pratiquement
indémontable.The pusher further comprises a
Le montage de ce poussoir s'effectue de la façon suivante :
A la figure 1, le poussoir est illustré en position bloquée, la coiffe 21 et le
corps 10 ne formant qu'un tout est vissé sur la tête 16 de l'axe de poussoir. Cet
axe ne peut pas tourner dans le tube de poussoir 1 du fait de la portion en six
pans de son extrémité coopérant avec l'alésage six pans du tube. De plus, la tête
de la vis de maintien 19 bute contre la face frontale libre du tube de poussoir 1.
Ainsi, en vissant la coiffe 21 et le corps 10 sur la tête 16 de l'axe de poussoir,
l'ensemble coiffe 2 et corps 10 est déplacé en direction du tube de poussoir 1, le
plan incliné 14 comprime le joint 6 et l'on obtient l'étanchéité maximale de l'ordre
de 100 bars entre le corps 10 et le tube de poussoir 1. Dans cette position la
fonction poussoir est bloquée.In FIG. 1, the pusher is illustrated in the locked position, the
Pour pouvoir utiliser la fonction poussoir, l'usager dévisse l'ensemble coiffe
21 et corps 10. Cet ensemble se déplace par rapport au tube 1 et à l'axe de
poussoir 15 jusqu'à ce que la tête 16 de cet axe de poussoir 15 bute contre la
nervure interne 11 du corps. Dans cette position illustrée à la figure 2, les joints 6
assurent toujours l'étanchéité bien qu'ils soient moins comprimés puisqu'ils ne
sont plus en contact avec la partie conique 14 du corps 10. Cette étanchéité
réduite de fonctionnement, est de l'ordre de 10 bars.To be able to use the pusher function, the user unscrews the
A partir de cette position illustrée à la figure 2, l'usager peur activer la
fonction poussoir en appuyant sur la coiffe 21 provoquant le déplacement axial de
l'axe de poussoir 15 par rapport au tube de poussoir 1 contre l'action du ressort de
rappel 20 pour arriver dans la position active illustrée à la figure 3 où la vis de
maintien 16 actionne un mécanisme. Cette position axiale active du poussoir est
limitée par l'entrée en contact de la nervure interne 11 du corps 10 avec la surface
supérieure du tube de poussoir 1.From this position illustrated in FIG. 2, the user can activate the
push-button function by pressing on the
Ce poussoir étanche blocable est particulièrement avantageux en ce qu'il est d'une grande simplicité et robustesse, que le nombre de ses pièces constitutives est réduit et que son utilisation est simple et fiable.This lockable waterproof pusher is particularly advantageous in that it is very simple and robust, that the number of its parts is reduced and its use is simple and reliable.
De plus, un avantage particulier de ce poussoir réside dans le fait que le ou
les joints sont placés à un seul endroit entre le tube de poussoir 1 et le corps de
poussoir 10. Cette étanchéité se trouve donc en amont du mécanisme de poussoir
lui-même par rapport au flux d'eau ou de poussière qui pourrait pénétrer entre le
tube et le corps. Ainsi, le filetage entre la tête 16 de l'axe de poussoir et le corps
10 ainsi que le ressort de rappel 20 sont protégés également des souillures
extérieures, ce qui n'est pas le cas dans les poussoirs antérieurs.In addition, a particular advantage of this pusher is that the or
the seals are placed in one place between the
Un autre avantage de ce poussoir réside dans le fait que la tige de poussoir
15 ne peut pas se déplacer angulairement par rapport au tube de poussoir 1, ce
qui réduit l'usure que peut subir le mécanisme commandé par un tel poussoir.Another advantage of this pusher is that the
La distance axiale x dont peut se déplacer la coiffe 21 et le corps 10 du
poussoir par rapport à la tête 16 de la tige du poussoir 15 est déterminée de
manière à ce qu'elle soit égale ou supérieure à la course active y du poussoir pour
effectuer sa fonction mais également égale ou inférieure à la distance z séparant
l'épaulement inférieur 4 du tube 1 du poussoir de la paroi latérale inférieure de la
gorge 5 recevant le ou les joints 6. De cette façon ces joints 6 sont toujours en
position active assurant l'étanchéité au moins de fonctionnement de 10 bars
environ.The axial distance x by which the
Dans des variantes, la partie supérieure du corps 10, nécessairement
ouverte pour le montage de l'axe de poussoir 15, pourrait être obturée par un
bouchon vissé ou tout autre organe de fermeture à la place de la coiffe 21.In variants, the upper part of the
