Abstract

Casing for electric jack presenting a maximum tightness, more particularly intended for automatic steering in boats. This casing (1), formed by a hollow metal section extending longitudinally, incorporates a means (2) deformable under the action of pressure variation inside the housing in which the jack rod (4) moves so as to balance the pressure inside said housing with that of the environment air in order to prevent water from coming inside by a pumping effect. The electrical switchings are provided by means of flexible strip switches controlled by magnet through a non-magnetic wall of the casing. There are also provided original means for fixing and guiding elements effecting relative motions.

Description

VERIN ETANCHE POUR PILOIE AUTOMATIQUE DE BATEAU. WATERPROOF JACK FOR AUTOMATIC BOAT PILOTING.
On sait que le développement de la navigation de plaisance a suscité la création d'un certain nombre de types de pilotes automatiques. Le modèle le plus répandu est constitué par un vérin électrique asservi à un compas magnétique qui, à partir d'un point fixe situé sur le bateau, agit directement sur labarre franche.We know that the development of pleasure boating has led to the creation of a certain number of types of automatic pilots. The most widespread model is constituted by an electric actuator controlled by a magnetic compass which, from a fixed point located on the boat, acts directly on the straight line.
Ces dispositifs sont de toute évidence placés obligatoirement à l'extérieur et de ce fait exposés aux embruns et paquets de mer, ce qui nécessite de prendre des précautions toutes spéciales pour les rendre étanches. Un tel vérin comprend des éléments mécaniques et électriques fragiles pour lesquels une protection efficace est indispensable.These devices are obviously placed outside and therefore exposed to sea spray and packets, which requires taking special precautions to make them waterproof. Such an actuator includes fragile mechanical and electrical elements for which effective protection is essential.
Suivant la technique antérieure des imperfections subsistent concernant principalement l'étanchéité du boîtier et l'effet de pompage résultant des mouvements alternatifs de la tige du vérin , desquels résultent des variations de volume, donc de pression,à l'intérieur du boîtier.According to the prior art, imperfections remain, mainly concerning the tightness of the housing and the pumping effect resulting from reciprocating movements of the cylinder rod, which result in variations in volume, and therefore in pressure, inside the housing.
Le dispositif suivant la présente invention permet de remédier efficacement aux inconvénients précités, au moyen notamment d'un élément deformable assurant l'équilibre entre la pression existant à l'intérieur du boîtier et la pression extérieure.The device according to the present invention makes it possible to effectively remedy the aforementioned drawbacks, in particular by means of a deformable element ensuring the balance between the pressure existing inside the housing and the external pressure.
L'invention concerne également des moyens se rapportant à la liaison réglable entre le bateau et le corps du vérin ainsi qu'à la liaison entre la tige et le corps de ce dernier.The invention also relates to means relating to the adjustable connection between the boat and the body of the jack as well as to the connection between the rod and the body of the latter.
L'invention concerne en outre des moyens électriques de commutation constitués par des lames en matériau magnétique souples, tels que des interrupteurs Reed, asservies à la position d'un aimant disposé à l'extérieur du boîtier, de telle sorte que les seuls points à rendre parfaitement étanches sont ceux par lesquels passent les fils de liaison à la source de courant..The invention further relates to electrical switching means constituted by blades of magnetic material. flexible, such as Reed switches, slaved to the position of a magnet disposed outside the housing, so that the only points to be made completely sealed are those through which the connecting wires pass to the current source. .
Le boîtier du vérin peut être favorablement formé d'un profilé creux développé longitudinalement et feimé à chacune de ses extrémités par des bouchons qui peuvent être déterminés de manière standard quel que soit le développement longitudinal donné au corps du boîtier.The cylinder housing can be favorably formed of a hollow profile developed longitudinally and feimé at each of its ends by plugs which can be determined in a standard manner whatever the longitudinal development given to the body of the housing.
Cette disposition permet d'obtenir beaucoup plus facilement une étanchéité parfaite puisqu'en effet il ne subsiste de joints qu'entre le corps du boîtier et les deux bouchons obturant respectivement les deux extrémités de celui-ci.This arrangement makes it possible to obtain a perfect seal much more easily since in fact there remain only seals between the body of the housing and the two plugs respectively closing the two ends of the latter.
On décrira ci-après un mode de réalisation suivant l'invention ainsi que des variantes en se référant aux figures annexées à titre d'exemple non limitatif.An embodiment according to the invention will be described below, as well as variants, with reference to the appended figures by way of nonlimiting example.
Les figures 1 et 1A représentent un mode de réalisation de l'élément deformable.Figures 1 and 1A show an embodiment of the deformable element.
Les figures 2 et 2A en représentent une variante de réalisation.Figures 2 and 2A show an alternative embodiment.
Les figures 3, 3A et 3B représentent une forme de réalisation d'un boîtier de vérin selon l'invention et ses moyens de réglage et de fixation en position.Figures 3, 3A and 3B show an embodiment of a cylinder housing according to the invention and its means of adjustment and fixing in position.
Les figures 4 et 4A représentent des moyens électriques de commutation prévus pour la commande de fonctionnement du vérin.FIGS. 4 and 4A represent electrical switching means provided for controlling the operation of the jack.
La figure 5 rappelle schématiquement comment est établie la liaison du vérin du pilote respectivement à la barre franche et au bateau. Elle permet une meilleure compréhension de la figure 3 et des figures 6 et 7 qui représentent des variantes des moyens de réglage et de fixation en position représentés sur la figure 3.FIG. 5 schematically recalls how the connection between the pilot cylinder and the tiller and the boat is established respectively. It allows a better understanding of the FIG. 3 and FIGS. 6 and 7 which represent variants of the adjustment and fixing means in position shown in FIG. 3.
La figure 1 représente schématiquement en coupe un vérin dont le boîtier est désigné par la référence 1 et à l'intérieur duquel est logé un élément deformable 2 en forme de soufflet. Ce volume deformable est en liaison avec l'air ambiant par un orifice 3. La référence 4 désigne la tige de vérin rendue solidaire du filetage 5 asservi à l'ensemble de commande de mouvement classique (non représenté).Figure 1 shows schematically in section a cylinder whose housing is designated by the reference 1 and inside which is housed a deformable element 2 in the form of a bellows. This deformable volume is connected to the ambient air through an orifice 3. The reference 4 designates the jack rod made integral with the thread 5 slaved to the conventional movement control assembly (not shown).
La figure LA. représente en perspective le volume défoimable 2 en forme de soufflet.Figure LA. shows in perspective the demountable volume 2 in the form of a bellows.
Les figures 2 et 2A représentent une variante suivant laquelle l'élément deformable est constitué par une membrane souple 6 logée dans une découpe 7 pratiquée dans le boîtier 1. Cette membrane est protégée par une grille 8.FIGS. 2 and 2A represent a variant according to which the deformable element consists of a flexible membrane 6 housed in a cutout 7 made in the housing 1. This membrane is protected by a grid 8.
La figure 3 représente un boîtier de vérin réalisé conformément à l'invention et ses moyens de réglage en position et de fixation.FIG. 3 represents a jack housing produced in accordance with the invention and its means for adjusting the position and fixing.
Le boîtier 1 est constitué par un profilé creux développé longitudinalement, fermé à ses extrémités par des bouchons 1a et 1b . Dans ce boîtier sont pratiqμées de part et d'autre des rainures 9 (dont une seule est visible sur la figure). Le support pivot 10 du vérin en forme d'U est pourvu à l'extrémité de chacune de ses branches d'un tenon de coulissement 11 mobile le long de la rainure 9 formant coulisse. Bien entendu une disposition symétrique existe sur la partie non visible du boîtier.The housing 1 is constituted by a hollow section developed longitudinally, closed at its ends by plugs 1a and 1b. In this housing are practiqμées on either side of the grooves 9 (of which only one is visible in the figure). The pivot support 10 of the U-shaped cylinder is provided at the end of each of its branches with a sliding pin 11 movable along the groove 9 forming a slide. Of course a symmetrical arrangement exists on the non-visible part of the housing.
Les figures 3A et 3B représentent à des échelles différentes, respectivement en perspective et en coupe, le mode de montage des tenons coulissants et la liaison avec le boîtier.FIGS. 3A and 3B show on different scales, respectively in perspective and in section, the method of mounting the sliding studs and the connection with the housing.
Le tenon 11 est solidaire de la plaque 12, elle-même solidaire de la plaque coulissante 13 au moyen des vis 14. Le déplacement longitudinal de la plaque 13 est limité par les bouchons la et 1b du boîtier. Le serrage de la plaque 12 sur la plaque 13 au moyen des vis 14 assure le blocage en position de l'ensemble.The pin 11 is integral with the plate 12, itself integral of the sliding plate 13 by means of the screws 14. The longitudinal movement of the plate 13 is limited by the plugs 1a and 1b of the housing. The tightening of the plate 12 on the plate 13 by means of the screws 14 ensures the locking in position of the assembly.
Les figures 4 et 4A représentent,à échelle différente,des moyens commutateurs-interrupteurs à lames souples, tels que des interrupteurs Reed, asservis à un aimant. Une pluralité de ces commutateurs-interrupteurs et aimants correspondants peut être prévue pour assurer la mise en fonctionnement, l'arrêt aussi bien que différentes autres commutations.Figures 4 and 4A show, on a different scale, switch-switch means with flexible blades, such as Reed switches, slaved to a magnet. A plurality of these switch-switches and corresponding magnets can be provided to ensure start-up, shutdown as well as various other switches.
Sur le boîtier de vérin 1 est fixé un capot 18 dans lequel un évidement de fo^me appropriée 19-19' est pratiqué de manière à permettre l'insertion et le maintien du bouton 20 et de l'aimant 21 solidaires entre eux.On the jack housing 1 is fixed a cover 18 in which a suitable form of recess 19-19 'is made so as to allow the insertion and maintenance of the button 20 and the magnet 21 integral with each other.
A l'intérieur du boîtier 1 est disposé le commutateur - interrupteur à lames 22 dont les deux lames portent respectivement les références 23 et 24. Cet élément de commutation es fixé sur une plaquette, telle que de circuit imprimé 25, la dite plaquette étant elle-même fixée à l'intérieur du boîtie Suivant que l'aimant 21 solidaire du bouton 20 est en regard ou non en superposition de l'interrupteur 22, le contact entr les lames 23 et 24 est assuré ou non. Il est évident que la commutation peut être inversée suivant la disposition correspondante.Inside the housing 1 is arranged the switch-switch with blades 22, the two blades of which bear the references 23 and 24 respectively. This switching element is fixed on a plate, such as on a printed circuit 25, said plate being -Even fixed inside the box Depending on whether the magnet 21 integral with the button 20 is facing or not superimposed on the switch 22, the contact between the blades 23 and 24 is ensured or not. It is obvious that the switching can be reversed according to the corresponding provision.
La figure 5, destinée à rappeler les mouvements relatifs des différents organes, indique schématiquement comment est établie la liaison du vérin du pilote respectivement à la bar et au bateau. Sur cette figure, la référence 26 désigne la ba franche et la référence 26& l'axe de rotation du safran qu'el entraîne. La tige du vérin 27 dont le boîtier est désigné par la référence 28 est reliée en 2βb à la barre, tandis que le pivot articulé 29 support du vérin est en rotation dans le support 30 solidaire du bateau. Dans ces conditions, lorsque la tige 27 sort du boîtier 28 ou rentre à l'intérieur de celui-ci, la barre est déplacée dechaque cδté par rapport à l'axe médian (position barre à zéro).FIG. 5, intended to recall the relative movements of the various members, schematically indicates how the connection of the pilot cylinder is established respectively to the bar and to the boat. In this figure, the reference 26 designates the frank ba and the reference 26 & the axis of rotation of the rudder that it drives. The rod of the jack 27 whose housing is designated by the reference 28 is connected in 2βb to the bar, while the articulated pivot 29 support of the jack is rotated in the support 30 secured to the boat. Under these conditions, when the rod 27 leaves the housing 28 or returns inside the latter, the bar is moved decently each side relative to the median axis (bar position at zero).
D'autre part, il est bien connu qu'en fonction des conditions de navigation (vent de travers, couple de l'hélice, ... ), il est souvent nécessaire de maintenir un angle permanent de barre. Cela est facile à obtenir si l'on déplace le pivot articulé 29 longitudinalement par rapport au boîtier du vérin 28 dans le sens indiqué par les flèches.On the other hand, it is well known that depending on the navigation conditions (crosswind, propeller torque, ...), it is often necessary to maintain a permanent rudder angle. This is easy to obtain if the articulated pivot 29 is moved longitudinally relative to the casing of the jack 28 in the direction indicated by the arrows.
La figure 3 représente un moyen coulissant permettant d'obtenir ce résultat, il en est de même des figures 6 et 7.FIG. 3 represents a sliding means making it possible to obtain this result, the same is true of FIGS. 6 and 7.
Sur la figure 6, la référence 31 désigne le boîtier du vérin (référencé 28 sur la figure 1), et la référence 32 désigne la vis de commande pénétrant dans la tige tubulaire 33 taraudée du vérin (référencée 27 sur la figure l).In FIG. 6, the reference 31 designates the casing of the jack (referenced 28 in FIG. 1), and the reference 32 denotes the control screw penetrating into the threaded tubular rod 33 of the jack (referenced 27 in FIG. 1).
A l'intérieur du boîtier 31 est disposé un élément 34 solidaire du tube 33 et pourvu d'oreilles 35 et 36 formant respectivement des coulisseaux logés dans les glissières que constituent respectivement les nervures 37 et 3d d'une part, 39 et 40 d'autre part, disposées longitudinalement sur les parois intérieures du boîtier 31.Inside the housing 31 is disposed an element 34 integral with the tube 33 and provided with ears 35 and 36 respectively forming slides housed in the slides which constitute the ribs 37 and 3d respectively on the one hand, 39 and 40 d ' on the other hand, arranged longitudinally on the interior walls of the housing 31.
Cet élément 34 interdit donc la rotation axiale de la tige rubulaire 33, ce qui provoque le coulissement de cette dernière pour produire les effets requis lorsque la vis 32 est mise en rotation.This element 34 therefore prohibits the axial rotation of the rod 33, which causes the latter to slide to produce the effects required when the screw 32 is rotated.
Suivant une autre caractéristique, le boîtier 31 est pourvu d'une saillie longitudinale 41 à section en T. La pièce 42 constituant le pivot articulé support du vérin (référencée 29 dans la figure 5) pourvue à sa partie supérieure d'une chape 43 est solidaire du bateau. Les moyens de liaison entre la pièce 42 et le boîtier 31 comprennent les deux pièces 44 et 45 dans lesquelles sont pratiquées des rainures 46 et 47 prévues pour permettre le coulissement de ces pièces le long de la saillie 41 .According to another characteristic, the housing 31 is provided with a longitudinal projection 41 with a T-section. The part 42 constituting the articulated pivot supporting the jack (referenced 29 in FIG. 5) provided at its upper part with a yoke 43 is attached to the boat. The connecting means between the part 42 and the housing 31 include the two parts 44 and 45 in which are formed grooves 46 and 47 provided to allow the sliding of these parts along the projection 41.
Les pièces 44 et 45 sont percées pour permettre le passage du boulon fileté 48 sûr lequel pivote lobrement la chape 43, et elles sont immobilisées sur le boîtier 31 au moyen de l'écrou moleté 49 et du boulon fileté 48.The parts 44 and 45 are drilled to allow the threaded bolt 48 to pass, which rotates the yoke 43 loosely, and they are immobilized on the housing 31 by means of the knurled nut 49 and the threaded bolt 48.
Les pièces 44 et 45 sont pourvues à leur partie inférieure de saillies complémentaires en forme de L, de telle sorte que les dites pièces puissent être immobilisées sur la saillie 41 avec un effet de pinçage, ce qui permet de diminuer considéra blement l'effort de serrage au moyen du boulon 48 et de l'écrou 49. Afin d'autoriser un certain pivotement du boîtier 31 autour d'un axe horizontal les pièces 44 et 45 sont embrèvées en 50 et 51, embrèvements dans lesquels la pièce 42 peut se déplacer.Parts 44 and 45 are provided at their lower part with additional L-shaped projections, so that said parts can be immobilized on projection 41 with a pinching effect, which makes it possible to considerably reduce the effort of tightening by means of the bolt 48 and the nut 49. In order to allow a certain pivoting of the housing 31 around a horizontal axis the parts 44 and 45 are dimpled at 50 and 51, dimples in which the part 42 can move .
Lorsque l'on desserre l'écrou moleté 49 les pièces 44 et 45 sont libérées et peuvent coulisser sur la partie en saillie 41, permettant ainsi de pouvoir choisir sur le boîtier la position appropriée pour prendre l'angle de barre permanent correspondant aux meilleures conditions de navigation.When the knurled nut 49 is loosened, the parts 44 and 45 are released and can slide on the projecting part 41, thus making it possible to be able to choose on the housing the appropriate position to take the angle of permanent bar corresponding to the best conditions. navigation.
Sur la figure 7 qui représente une variante de disposition, au boulon 48 de la figure 6 est substitué un axe désigné par la référence 52. Cet axe est fileté à une de ses extrémités pour recevoir l'écrou 53» tandis que son autre extrémité est formée par la partie 54 dans laquelle une perforation est pratiquée. La fixation en place de cet axe est déterminée de la façon suivante : une vis ou une clavette 55 est prévue pou réunir l'extrémité 54 de l'axe 52 à la pièce 56 dans laquelle est ménagé un évidement pour le logement de la partie 54 de l'axe 52. Un trou excentré 58 est pratiqué dans la pièce 56, dont la position de verrouillage est représentée en traits pleins. Le déplacement de 902 en rotation du levier de la pièce 56 permet d'obtenir le serrage ou le desserrage immédiat des pièces 44 et 45,sous réserve que l'on ait au préalable réglé la position de l'écrou 53. I1 est rappelé que le boîtier du vérin peut être réalisé favorablement dans un profilé , tel qu'extrudé, en alliage léger par exemple.In FIG. 7 which represents an alternative arrangement, the bolt 48 of FIG. 6 is replaced by an axis designated by the reference 52. This axis is threaded at one of its ends to receive the nut 53 "while its other end is formed by the part 54 in which a perforation is made. The fixing in place of this axis is determined as follows: a screw or a key 55 is provided for joining the end 54 of the axis 52 to the part 56 in which is formed a recess for the housing of the part 54 of the axis 52. An eccentric hole 58 is made in the part 56, the locking position of which is shown in solid lines. The movement of 902 in rotation of the lever of the part 56 makes it possible to obtain the immediate tightening or loosening of the parts 44 and 45, provided that the position of the nut 53 has been previously adjusted. I1 is reminded that the cylinder housing can be made favorably in a profile, such as extruded, in light alloy for example.
