Ledit élément longitudinal 15 comporte, dans l'exemple représenté, une série d'encoches 40 disposées suivant une ligne périphérique droite 41 parallèle à l'axe longitudinal de déplacement dudit élément mobile et en regard des goupilles 17. Ces encoches 40 ont une zone centrale 41 dont la profondeur est maximale et deux zones latérales 42 et 43 en pente rejoignant la zone centrale 41. Elles sont agencées pour coopérer avec les goupilles 17 afin d'assurer une fonction de freinage et/ou de blocage du dispositif en fonction de la position dudit noyau central 13 à l'intérieur du logement cylindrique 12.Said longitudinal element 15 comprises, in the example shown, a series of notches 40 arranged along a straight peripheral line 41 parallel to the longitudinal axis of movement of said movable member and facing the pins 17. These notches 40 have a central zone 41 whose depth is maximum and two lateral zones 42 and 43 in slope joining the central zone 41. They are arranged to cooperate with the pins 17 in order to ensure a function of braking and / or blocking of the device according to the position of said central core 13 inside the cylindrical housing 12.
Les figures 3A et 3B représentent des vues en coupe du dispositif 10 dans différentes phases au cours de son utilisation. La phase de repos, correspondant au libre déplacement de l'élément allongé 15 dans le passage traversant 14 du boîtier 11 est représentée par la figure 3A. Le noyau central 13 est maintenu dans sa position haute à l'intérieur du logement cylindrique 12. De ce fait, les goupilles 17 sont entièrement dégagées des encoches 40 et aucun freinage ni blocage ne peut se faire par engagement des goupilles dans les encoches. Le déplacement de l'élément allongé 15 est entièrement libre.Figures 3A and 3B show sectional views of the device 10 in different phases during its use. The rest phase, corresponding to the free movement of the elongated element 15 in the through passage 14 of the housing 11 is represented by FIG. 3A. The central core 13 is held in its high position inside the cylindrical housing 12. As a result, the pins 17 are completely clear of the notches 40 and no braking or blocking can be done by engagement of the pins in the notches. The displacement of the elongated element 15 is entirely free.
La figure 3B illustre une phase de freinage et/ou de blocage dans laquelle le noyau central 13 est disposé à une distance suffisante de la plaque d'arrêt 20 pour que les têtes des goupilles 17 soient engagées dans les encoches 40. Les ressorts de poussée 18 exercent une force plus ou moins forte sur les goupilles 17 pour assurer un freinage plus ou moins fort lorsque l'élément allongé 15 est entraîné en translation par rapport au boîtier 11. Ce freinage est dû à la friction des têtes de goupilles 17 sur le fond des encoches 40. La double rampe 41 , 42 de ces encoches 40 constitue une rampe d'entrée et une rampe de sortie des goupilles 17 correspondantes. La force de freinage dépend de la force exercée par les ressorts de poussée 18, donc de la distance qui sépare le noyau central 13 de la plaque d'arrêt 20.FIG. 3B illustrates a braking and / or locking phase in which the central core 13 is disposed at a sufficient distance from the stop plate 20 so that the heads of the pins 17 are engaged in the notches 40. The thrust springs 18 exert a more or less strong force on the pins 17 to provide more or less strong braking when the elongate member 15 is driven in translation relative to the housing 11. This braking is due to the friction of the pins 17 on the The double ramp 41, 42 of these notches 40 constitutes an inlet ramp and an exit ramp of the corresponding pins 17. The braking force depends on the force exerted by the thrust springs 18, hence the distance between the central core 13 and the stop plate 20.
Le nombre de lignes 41 d'encoches peut être varié ainsi que le nombre de goupilles 17 qui travaillent sur une même ligne d'encoches selon les résultats que l'on souhaite atteindre.The number of lines 41 of notches can be varied as well as the number of pins 17 which work on the same line of notches according to the results that one wishes to achieve.
Les figures 4, 5A, 5B et 5C illustrent une deuxième forme de réalisation dans laquelle l'élément allongé a la forme d'une barre plate de section rectangulaire et comporte deux lignes d'encoches. Comme le montre en particulier la vue en perspective explosée de la figure 4, le dispositif 50 de l'invention comprend un boîtier 51 dans lequel est ménagé un logement cylindrique 52 contenant un noyau central 53 agencé pour coulisser axialement dans ledit logement 52 selon la double flèche B. Le boîtier 51 comporte un passage traversant 54 dont l'axe est sensiblement perpendiculaire à l'axe du logement cylindrique 52. Ce passage traversant 54 est agencé pour contenir un élément allongé 55 susceptible de coulisser axialement à l'intérieur dudit passage 54. Dans l'exemple représenté, le passage traversant 54 et l'élément allongé 55 ont une section rectangulaire.Figures 4, 5A, 5B and 5C illustrate a second embodiment in which the elongate member is in the form of a flat bar of rectangular section and has two lines of notches. As is shown in particular in the exploded perspective view of FIG. 4, the device 50 of the invention comprises a housing 51 in which is formed a cylindrical housing 52 containing a central core 53 arranged to slide axially in said housing 52 along the double arrow B. The housing 51 has a through passage 54 whose axis is substantially perpendicular to the axis of the housing cylindrical 52. This through passage 54 is arranged to contain an elongate member 55 slidable axially within said passage 54. In the example shown, the through passage 54 and the elongate member 55 have a rectangular section.
Ledit noyau central 53 comporte, dans l'exemple illustré, deux alésages 56 agencés pour recevoir respectivement une goupille 57 sollicitée par un ressort de poussée 58 maintenu dans l'alésage 56 correspondant par une pièce tubulaire 59 également engagée dans ledit alésage 56. Le noyau central 53 est engagé dans le logement cylindrique 52 et recouvert d'une plaque d'arrêt 60 fixée audit boîtier 51 par deux vis 61. Le noyau central 53 est pourvu d'un alésage fileté 62 dans lequel est vissée partiellement une pièce de couplage 63 comprenant un secteur inférieur fileté 64 surmonté d'une collerette 65 définissant un arrêt prenant appui contre la surface supérieure dudit noyau central 53. Dans sa partie supérieure, la pièce de couplage 63 comporte un secteur cylindrique 66 agencé pour traverser un alésage central 67 de la plaque d'arrêt 60, ledit secteur cylindrique 66 étant surmonté d'un embout 68 destiné à solidariser la pièce de couplage 63 et un organe de commande 69, par exemple une manette, dont la fonction sera décrite par la suite. Une goupille (non représentée) est engagée dans une ouverture 70 de la manette de commande 69 et dans une ouverture correspondante 71 de l'embout 68 pour solidariser ladite manette de commande 69 et ladite pièce de couplage 63.Said central core 53 comprises, in the illustrated example, two bores 56 arranged to respectively receive a pin 57 biased by a thrust spring 58 held in the corresponding bore 56 by a tubular piece 59 also engaged in said bore 56. The core central 53 is engaged in the cylindrical housing 52 and covered with a stop plate 60 fixed to said housing 51 by two screws 61. The central core 53 is provided with a threaded bore 62 in which is partially screwed a coupling piece 63 comprising a threaded lower sector 64 surmounted by a collar 65 defining a stop bearing against the upper surface of said central core 53. In its upper part, the coupling piece 63 comprises a cylindrical sector 66 arranged to pass through a central bore 67 of the stop plate 60, said cylindrical sector 66 being surmounted by a tip 68 for securing the coupling piece 63 and a body of e command 69, for example a joystick, whose function will be described later. A pin (not shown) is engaged in an opening 70 of the control handle 69 and in a corresponding opening 71 of the end piece 68 for securing said control handle 69 and said coupling piece 63.
Ledit élément longitudinal 55 comporte, dans l'exemple représenté, deux lignes 41 d'encoches disposées respectivement en regard des deux goupilles 57, ces encoches 40 ayant la même géométrie que les encoches 40 décrites précédemment. Ces encoches sont agencées pour coopérer avec les goupilles 57 afin d'assurer une fonction de freinage et/ou de blocage du dispositif en fonction de la position dudit noyau central 53 à l'intérieur du logement cylindrique 52. Le nombre de goupilles travaillant respectivement avec les encoches 40 de chaque ligne pourrait être augmenté selon la puissance de freinage ou de blocage recherchée. Le nombre de lignes d'encoches pourrait être supérieur à deux. Comme le montre plus particulièrement la figure 5C, le boîtier 51 a une section supérieure inférieure à la section dans la partie inférieure. Toutefois cette géométrie pourrait être changée et le boîtier 51 pourrait avoir une secticn rectangulaire invariable sur toute sa hauteur.Said longitudinal element 55 comprises, in the example shown, two lines 41 of notches respectively arranged opposite the two pins 57, these notches 40 having the same geometry as the notches 40 described above. These notches are arranged to cooperate with the pins 57 in order to ensure a function of braking and / or locking of the device as a function of the position of said central core 53 inside the cylindrical housing 52. The number of pins working respectively with the notches 40 of each line could be increased according to the desired braking or blocking power. The number of lines of notches could be greater than two. As shown more particularly in Figure 5C, the housing 51 has a lower upper section than the section in the lower part. However this geometry could be changed and the housing 51 could have a rectangular secticn invariable on all its height.
Les figures 6, 7A et 7B représentent une troisième forme de réalisation du dispositif 80 qui diffère de celle des figures 1 , 2, 3A et 3B en ce que la ligne d'encoches 40, qui coopère avec les goupilles pour assurer la fonction de freinage et de blocage, est une ligne périphérique circulaire 81 disposée dans un plan radial perpendiculaire à l'axe longitudinal de déplacement de l'élément mobile 15. Les autres composants du dispositif 80 sont identiques aux composants correspondants du dispositif 10 décrit en référence aux figures mentionnées et portent les mêmes numéros de référence.Figures 6, 7A and 7B show a third embodiment of the device 80 which differs from that of Figures 1, 2, 3A and 3B in that the notch line 40, which cooperates with the pins to provide the braking function and locking, is a circular peripheral line 81 disposed in a radial plane perpendicular to the longitudinal axis of movement of the movable member 15. The other components of the device 80 are identical to the corresponding components of the device 10 described with reference to the figures mentioned and bear the same reference numbers.
On notera que l'élément allongé 15 porte deux lignes 81 d'encoches, parallèles entre elles et disposées dans deux plans radiaux qui correspondent aux deux goupilles 17 comme illustré par la figure 7A. Dans ce cas, le but du dispositif 80 est d'assurer un freinage en rotation de l'élément allongé par rapport au boîtier 11 comme illustré par la figure 7B. Une des applications est par exemple un système de commande de vannes où le déplacement en rotation d'un axe doit pouvoir être effectué progressivement et contrôlé dans chaque position. Le nombre de lignes 81 d'encoches n'est pas limité. Il dépend du nombre de goupilles 17 montées dans le noyau central 13.Note that the elongated element 15 carries two lines 81 of notches, parallel to each other and arranged in two radial planes which correspond to the two pins 17 as shown in Figure 7A. In this case, the purpose of the device 80 is to provide rotational braking of the elongate member relative to the housing 11 as shown in Figure 7B. One of the applications is for example a valve control system where the rotational displacement of an axis must be able to be carried out gradually and controlled in each position. The number of lines 81 of notches is not limited. It depends on the number of pins 17 mounted in the central core 13.
Les figures 8A et 8B représentent une forme de réalisation spécifique du dispositif 100 utilisé dans le contexte d'une drisse ou d'un tendeur de câble. Dans cette forme de réalisation, le dispositif comporte un boîtier 101 , identique aux boîtiers 11 et 51 décrits précédemment, mais en outre pourvu de deux prolongements latéraux 102 agencés pour être fixés de manière pivotante à une embase 103, par exemple fixée par vissage sur Ie pont d'un bateau, lorsque le dispositif est conçu pour servir de tendeur d'un câble d'attache d'un mât ou similaire. Le boîtier 101 est pourvu d'un passage traversant de section circulaire agencé pour recevoir un élément allongé cylindrique 15.Figures 8A and 8B show a specific embodiment of the device 100 used in the context of a halyard or cable tensioner. In this embodiment, the device comprises a housing 101, identical to the housings 11 and 51 described above, but also provided with two lateral extensions 102 arranged to be pivotally attached to a base 103, for example fixed by screwing on the deck of a boat, when the device is designed to serve as a tensioner of a mast attachment cable or the like. The housing 101 is provided with a through passage of circular section arranged to receive an elongated cylindrical element 15.
L'élément allongé 15, qui coulisse dans le boîtier 101 , comporte une ligne périphérique droite 41 d'encoches 40 agencées pour coopérer, comme décrit en référence aux figures précédentes, avec des goupilles 17 logées dans le boîtier 101. Cet élément 15 comporte à son extrémité libre un secteur fileté 104 permettant son couplage avec une pièce mécanique, par exemple une pièce (non représentée) qui fixe un câble ou un œillet d'accrochage d'une corde, ou une tringle ou similaire. Lorsque ce dispositif est utilisé pour fixer un câble d'attache d'un mât de bateau par exemple, en cas de tension excessive, c'est-à- dire lorsque, suite à des conditions de navigation extrêmes la tension sur Ie câble dépasse un certain seuil, le dispositif, préalablement réglé à une valeur déterminée, permet de libérer une certaine tension et d'éviter une rupture de câble entraînant un accident. Ce même cas peut se produire sur une structure métallique, telle qu'une grue, dont des montants sont sécurisés par des câbles. Le fait de libérer une certaine tension lorsque celle-ci atteint un seuil critique permet d'éviter des accidents dus à des ruptures de câbles ou de tringles de liaison ou similaires. D'autres applications sont envisageables. Le réglage du seuil de relâchement de la tension est réglable dans chaque cas et selon les besoins spécifiques. The elongated element 15, which slides in the housing 101, comprises a straight peripheral line 41 of notches 40 arranged to cooperate, as described with reference to the preceding figures, with pins 17 housed in the housing 101. This element 15 comprises its free end a threaded sector 104 for coupling with a mechanical part, for example a part (not shown) which fixes a rope or a hooking eyelet of a rope, or a rod or the like. When this device is used to fix a cable for attaching a boat mast, for example, in the event of excessive tension, that is to say when, following extreme navigation conditions, the tension on the cable exceeds one certain threshold, the device, previously set at a determined value, allows to release a certain tension and to avoid a cable break resulting in an accident. This same case can occur on a metal structure, such as a crane, the amounts of which are secured by cables. Releasing a certain voltage when it reaches a critical threshold avoids accidents due to breaks in cables or connecting rods or the like. Other applications are possible. The setting of the voltage release threshold is adjustable in each case and according to specific needs.
