Definitions
- the present invention relates to a device for locking a sliding body, and in particular a retractable road terminal, in at least two predetermined positions to which it can be recalled by a control device comprising means of action in rotation acting on a rod.
- locking device which extends parallel to the sliding axis of the sliding body and which can rotate around its longitudinal axis, but cannot move parallel to it: see FR-A-2 621 625.
- a retractable bollard is to temporarily block space for vehicles, while allowing pedestrians to pass, when it is in the high position where it protrudes above the ground, but to allow people authorized to enter their vehicle into the space in question after the bollard has been retracted into the ground, for example by hand.
- Various locking systems are known for blocking such terminals in their high position and / or in their low position, but they are not satisfactory, in particular because of their insufficient reliability, their fragility and the possibility of forcing them by vandalism, however another drawback results from the fact that users can neglect to return the bollard to the high position after their passage.
- An object of the present invention is therefore to provide a locking device of the kind specified above which overcomes these drawbacks of known systems and which, in particular, is solid and reliable, while being relatively inexpensive.
- Another object is to provide such a device which prevents users from leaving the terminal in the retracted position, that is to say in the low position, after the passage of their vehicle.
- An additional aim is to shield a device of this kind from the harmful action of external agents such as surface water, dust, sand and gravel.
- these aims, as well as others which will appear subsequently, such as the automatic take-up of clearances and wear, are achieved by means of a device of the kind specified at the start which is characterized in that said rod has a plurality of transverse notches, the number and the mutual distance along the rod are respectively equal to the number and the mutual distance of the predetermined positions of the sliding body, the bottom of which is convex and connects to the cylindrical lateral surface of the rod and which are angularly spaced from each other around the longitudinal axis of the locking rod when viewed in the direction of the axis of the latter, without overlap between two successive notches; said locking device also comprising a bolt device secured to the sliding body and capable of penetrating into the aforementioned notches under the effect of an elastic force; and means for rotating the locking rod specified above about its axis, in order to bring it successively into predetermined angular positions where, for each of them, one of the transverse notches of the rod, seen in the direction of the axis of the
- the bolt is pushed by an elastic force into a notch in the locking rod according to the invention for each predetermined position of the sliding body, that is to say for example for the high position and for the low position in the case of a retractable road terminal. If the rod in question is then rotated, the point of contact between the bottom of the convex notch and the end of the bolt increases in distance from the axis of the rod and the bolt is pushed back towards the outside by sliding on the bottom of the notch.
- each notch thereof is delimited, in the radial direction, by a bottom formed by a cylindrical surface of revolution whose axis, parallel to the axis of the locking rod, is situated between this axis and the lateral surface of this rod or, and, in the axial direction, by two plane shoulders perpendicular to the axis of the locking rod, these therefore having the shape of a crescent comprised between the arc of a circle of the cylindrical lateral surface of the locking rod and the arc of a circle of the cylindrical surface of the bottom of the notch.
- the imaginary line which connects the two points of intersection of these arcs of circle will be called “chord of the notch" in what follows.
- the locking rod of the device comprises two transverse notches which are, for example, angularly offset by approximately 90 ° relative to one another when they are seen in the direction of the axis of the rod. This means that it is a quarter turn rotation of the rod in one direction or the other which will move from one notch to another or vice versa, that is to say from the position low to the high position or vice versa in the case of a road terminal.
- the bolt device specified above advantageously comprises a guide cylinder mounted on the sliding body perpendicular to the sliding axis thereof, a bolt proper which is slidably mounted inside the guide cylinder and the free end of which has dimensions allowing it to penetrate into the transverse notches of the locking rod, a compression spring inserted between the bottom of the guide cylinder and the bolt itself and a tenon integral with the bolt itself said and sliding in an elongated lumen which is formed in the side wall of the guide cylinder and which extends parallel to the axis of the latter.
- the means specified above which make it possible to rotate the locking rod according to the invention about its axis comprise a prismatic endpiece which projects at one of the ends of this rod and whose edges are parallel to the axis of the latter, as well as an operating key terminated by a female imprint reproducing in hollow the cross-sectional shape of the aforementioned prismatic tip.
- This end piece whose cross section is for example triangular can be made in one piece with the locking rod, but it can also be part of a barrel interchangeably mounted at one of its ends, so that it is easy to periodically change the key model, which reduces the risk use by unauthorized persons.
- an access plate is fixedly mounted beyond the prismatic end piece of the locking rod, in a plane perpendicular to the axis of the latter, this access plate being provided in the extension of the rod. , an opening which is intended for the passage of the operating key and whose shape corresponds to that of the outer periphery of the key in question.
- the locking rod can only be actuated by a key corresponding to the model in service, not only by its internal imprint, but also by its external contour.
- such an access plate largely protects the locking device against the intrusion of tools which would try to force it.
- the outer contour of the operating key when it covers the prismatic end of the locking rod, is not in exact alignment with the opening in the access plate only for one of the predetermined angular positions of the locking rod, and therefore of the sliding body, the key can only be removed through the opening of the access plate if one has previously placed the locking rod in the predetermined position which authorizes this operation.
- the only angular position allowing the extraction of the key is chosen, that which corresponds to the upper position of the terminal, so that the user cannot recover his key only if he has taken care to put the terminal in this high position.
- the protection of the device according to the invention against external agents such as runoff, dust and sand is advantageously ensured by means of a hatch with automatic closure which is arranged above the locking rod at ground level.
- the locking rod according to the invention comprises a notch for retaining and returning to the angular position, the bottom of which is constituted by a plurality of flats, each of these corresponding to one of the predetermined angular positions that the we want to maintain and extending parallel in space to the cord of the corresponding notch, and into which penetrates a branch of an L-shaped lever which is resiliently biased towards the bottom of the notch and the other branch of which is articulated by its end on a fixed element.
- This kind of latching ensures the maintenance of the locking rod in each of its angular positions which corresponds to one of the predetermined positions of the sliding body and also its return to the nearest position.
- the device which controls the movements of the sliding body that is to say for example of the road bollard
- it could be the pneumatic mechanism described in French patent No. 86 05310 of April 4, 1986, but also a simple spring which is compressed by hand by pushing on the terminal in order to bring it to the low position, and which relaxes when the locking device according to the invention allows the terminal to return to its high position .
- the female imprint of the latter comes to cover the prismatic endpiece (19) of the locking rod (7), as mentioned above. He then turns his key a quarter turn in the direction imposed by the stops (20) of the rod (7) and the mechanism constituted by the lever (21), the tension spring (24) and the flats ( 25) causes the rod (7) to jump to its other extreme position. During this time, the free end of the bolt (13) slides on the cylindrical bottom of the notch (17a) and the bolt (13) is pushed outwards against the spring (14).
- the translation carriage (2) When it is completely out of the notch (17a), the translation carriage (2) is free to move downward, under the effect of its control means which can simply consist of a manual push exerted on the road terminal (1) against a compression spring, the free end of the bolt (13) sliding on one of the generatrices of the rod (7) until it enters the lower notch (17b) under the effect of the spring (14), which blocks the downward progression of the translation carriage (2), and therefore of the terminal (1) which is then in the retracted position.
- the assembly of the assembly formed by the terminal (1) and the translation carriage (2) is also prevented by the latching of the bolt (13) in the notch (17b) of the locking rod (7).
- This operation is accompanied by the push of the bolt (13) out of the lower notch (17b) of the rod (7), the sliding of the free end of the latter along a generatrix of the rod ( 7), under the effect of the control mechanism which tends to raise the translation carriage (2) and the terminal (1) and therefore the bolt (13) which is integral therewith, and of its snapping into the upper notch (17a) of the rod (7) which is then in its path.
- this device could include a number of locking positions greater than two, by providing a corresponding number of notches (17) located at the desired locations along the rod (7) and angularly offset relative to the others at an angle such as the bolt (13), when it has left a notch due to the rotation of the rod (7) and it slides on a generator of the latter, necessarily meets the notch targeted in which it can then snap into place.
- the prismatic endpiece (19) which is intended to be capped by the operating key C could be, not in one piece with the rod (7), but formed on an interchangeable barrel.
- the assembly of the latter in the cage (4) could call on other devices only to the clamp (8) and to the bearing (9), and, moreover, the outline of the opening (27) of the access plate (26) could differ from that shown in FIG.
- the number of flats (25) formed in the notch (23) of the rod (7) for the purpose of latching the latter in each of its positions should be equal to that of the locking positions, each flat being parallel in space to the chord of the corresponding notch (17).

Abstract
Description
La présente invention concerne un dispositif permettant de verrouiller un corps coulissant, et notamment une borne de voirie rétractable, dans au moins deux positions prédéterminées vers lesquelles il peut être rappelé par un dispositif de commande comportant des moyens d'action en rotation agissant sur une tige de verrouillage qui s'étend parallèlement à l'axe de coulissement du corps coulissant et qui peut tourner autour de son axe longitudinal, mais non se déplacer parallèlement à celui-ci : voir FR-A-2 621 625.The present invention relates to a device for locking a sliding body, and in particular a retractable road terminal, in at least two predetermined positions to which it can be recalled by a control device comprising means of action in rotation acting on a rod. locking device which extends parallel to the sliding axis of the sliding body and which can rotate around its longitudinal axis, but cannot move parallel to it: see FR-A-2 621 625.
On sait que la fonction d'une borne de voirie rétractable est de barrer provisoirement un espace aux véhicules, tout en laissant passer les piétons, lorsqu'elle est en position haute où elle fait saillie au-dessus du sol, mais de permettre aux personnes autorisées de faire pénétrer leur véhicule dans l'espace en question après que la borne a été rétractée dans le sol, par exemple à la main. On connaît divers systèmes de verrouillage destinés à bloquer de telles bornes dans leur position haute et/ou dans leur position basse, mais ils ne donnent pas satisfaction, notamment à cause de leur fiabilité insuffisante, de leur fragilité et de la possibilité de les forcer par vandalisme, cependant qu'un autre inconvénient résulte de ce que les utilisateurs peuvent négliger de ramener la borne en position haute après leur passage.We know that the function of a retractable bollard is to temporarily block space for vehicles, while allowing pedestrians to pass, when it is in the high position where it protrudes above the ground, but to allow people authorized to enter their vehicle into the space in question after the bollard has been retracted into the ground, for example by hand. Various locking systems are known for blocking such terminals in their high position and / or in their low position, but they are not satisfactory, in particular because of their insufficient reliability, their fragility and the possibility of forcing them by vandalism, however another drawback results from the fact that users can neglect to return the bollard to the high position after their passage.
Un but de la présente invention est donc de proposer un dispositif de verrouillage du genre spécifié plus haut qui pallie ces inconvénients des systèmes connus et qui, en particulier, soit solide et fiable, tout en étant relativement peu coûteux.An object of the present invention is therefore to provide a locking device of the kind specified above which overcomes these drawbacks of known systems and which, in particular, is solid and reliable, while being relatively inexpensive.
Un autre but est de fournir un tel dispositif qui empêche les utilisateurs de laisser la borne en position rétractée, c'est-à-dire en position basse, après le passage de leur véhicule.Another object is to provide such a device which prevents users from leaving the terminal in the retracted position, that is to say in the low position, after the passage of their vehicle.
Un but supplémentaire est de soustraire un dispositif de ce genre à l'action néfaste des agents extérieurs comme les eaux de ruissellement, les poussières, le sable et le gravier.An additional aim is to shield a device of this kind from the harmful action of external agents such as surface water, dust, sand and gravel.
Selon l'invention, ces buts, ainsi que d'autres qui apparaîtront par la suite, comme le rattrapage automatique des jeux et de l'usure, sont atteints grâce à un dispositif du genre spécifié au début qui est caractérisé par le fait que ladite tige présente une pluralité d'encoches transversales dont le nombre et la distance mutuelle le long de la tige sont respectivement égaux au nombre et à la distance mutuelle des positions prédéterminées du corps coulissant, dont le fond est convexe et se raccorde à la surface latérale cylindrique de la tige de verrouillage et qui sont angulairement espacées les unes par rapport aux autres autour de l'axe longitudinal de la tige de verrouillage lorsqu'elles sont vues dans la direction de l'axe de celle-ci, sans qu'il y ait recouvrement entre deux encoches successives ; ledit dispositif de verrouillage comprenant également un dispositif à pène solidaire du corps coulissant et susceptible de pénétrer dans les encoches précitées sous l'effet d'une force élastique ; et des moyens pour faire tourner la tige de verrouillage spécifiée plus haut autour de son axe, afin de l'amener successivement dans des positions angulaires prédéterminées où, pour chacune d'elles, l'une des encoches transversales de la tige, vue dans la direction de l'axe de cette dernière, s'ouvre vers l'extérieur dans la direction du pène qui est destiné à y pénétrer.According to the invention, these aims, as well as others which will appear subsequently, such as the automatic take-up of clearances and wear, are achieved by means of a device of the kind specified at the start which is characterized in that said rod has a plurality of transverse notches, the number and the mutual distance along the rod are respectively equal to the number and the mutual distance of the predetermined positions of the sliding body, the bottom of which is convex and connects to the cylindrical lateral surface of the rod and which are angularly spaced from each other around the longitudinal axis of the locking rod when viewed in the direction of the axis of the latter, without overlap between two successive notches; said locking device also comprising a bolt device secured to the sliding body and capable of penetrating into the aforementioned notches under the effect of an elastic force; and means for rotating the locking rod specified above about its axis, in order to bring it successively into predetermined angular positions where, for each of them, one of the transverse notches of the rod, seen in the direction of the axis of the latter, opens outward in the direction of the bolt which is intended to penetrate there.
On comprend que, dans ce dispositif, le pène est poussé par une force élastique dans une encoche de la tige de verrouillage selon l'invention pour chaque position prédéterminée du corps coulissant, c'est-à-dire par exemple pour la position haute et pour la position basse dans le cas d'une borne de voirie rétractable. Si l'on fait alors tourner la tige en question, le point de contact entre le fond de l'encoche convexe et l'extrémité du pène voit augmenter sa distance par rapport à l'axe de la tige et le pène est repoussé vers l'extérieur en glissant sur le fond de l'encoche. Il arrive alors un moment où il n'est plus retenu par l'encoche, et où il peut glisser le long d'une génératrice de la surface latérale cylindrique de la tige de verrouillage sous l'effet du dispositif de commande qui agit sur le corps coulissant, et ce jusqu'à ce qu'il rencontre l'encoche suivante de la tige, dans laquelle il pénètre, de sorte qu'il se trouve bloqué, ce qui arrête le déplacement du corps coulissant qui en est solidaire.It is understood that, in this device, the bolt is pushed by an elastic force into a notch in the locking rod according to the invention for each predetermined position of the sliding body, that is to say for example for the high position and for the low position in the case of a retractable road terminal. If the rod in question is then rotated, the point of contact between the bottom of the convex notch and the end of the bolt increases in distance from the axis of the rod and the bolt is pushed back towards the outside by sliding on the bottom of the notch. There then comes a time when it is no longer retained by the notch, and when it can slide along a generatrix of the cylindrical lateral surface of the locking rod under the effect of the control device which acts on the sliding body, and this until it meets the next notch of the rod, into which it enters, so that it is blocked, which stops the movement of the sliding body which is integral therewith.
Selon une forme de réalisation de l'invention qui est particulièrement avantageuse, notamment en ce qui concerne l'usinage de la tige de verrouillage, chaque encoche de celle-ci est délimitée, dans le sens radial, par un fond constitué par une surface cylindrique de révolution dont l'axe, parallèle à l'axe de la tige de verrouillage, est situé entre cet axe et la surface latérale de cette tige ou au-delà, et, dans le sens axial, par deux épaulements plans perpendiculaires à l'axe de la tige de verrouillage, ceux-ci présentant donc la forme d'un croissant compris entre l'arc de cercle de la surface latérale cylindrique de la tige de verrouillage et l'arc de cercle de la surface cylindrique du fond de l'encoche. Pour des raisons de commodité, la droite imaginaire qui relie les deux points d'intersection de ces arcs de cercle sera appelée "corde de l'encoche" dans ce qui va suivre.According to an embodiment of the invention which is particularly advantageous, in particular with regard to the machining of the locking rod, each notch thereof is delimited, in the radial direction, by a bottom formed by a cylindrical surface of revolution whose axis, parallel to the axis of the locking rod, is situated between this axis and the lateral surface of this rod or, and, in the axial direction, by two plane shoulders perpendicular to the axis of the locking rod, these therefore having the shape of a crescent comprised between the arc of a circle of the cylindrical lateral surface of the locking rod and the arc of a circle of the cylindrical surface of the bottom of the notch. For reasons of convenience, the imaginary line which connects the two points of intersection of these arcs of circle will be called "chord of the notch" in what follows.
Dans le cas le plus simple où il est seulement prévu deux positions prédéterminées pour le corps coulissant, à savoir par exemple une position basse rétractée et une position haute en saillie au-dessus du sol pour une borne de voirie rétractable, la tige de verrouillage du dispositif selon l'invention comporte deux encoches transversales qui sont, par exemple, décalées angulairement de 90° environ l'une par rapport à l'autre lorsqu'elles sont vues dans la direction de l'axe de la tige. Ceci veut dire que c'est une rotation d'un quart de tour de la tige dans un sens ou dans l'autre qui fera passer d'une encoche à l'autre ou inversement, c'est-à-dire de la position basse à la position haute ou inversement dans le cas d'une borne de voirie.In the simplest case where only two predetermined positions are provided for the sliding body, namely for example a low retracted position and a high position projecting above the ground for a retractable road terminal, the locking rod of the device according to the invention comprises two transverse notches which are, for example, angularly offset by approximately 90 ° relative to one another when they are seen in the direction of the axis of the rod. This means that it is a quarter turn rotation of the rod in one direction or the other which will move from one notch to another or vice versa, that is to say from the position low to the high position or vice versa in the case of a road terminal.
En ce qui concerne le dispositif à pène spécifié plus haut, il comprend avantageusement un cylindre de guidage monté sur le corps coulissant perpendiculairement à l'axe de coulissement de celui-ci, un pène proprement dit qui est monté en coulissement à l'intérieur du cylindre de guidage et dont l'extrémité libre présente des dimensions lui permettant de pénétrer dans les encoches transversales de la tige de verrouillage, un ressort de compression inséré entre le fond du cylindre de guidage et la pène proprement dit et un tenon solidaire du pène proprement dit et coulissant dans une lumière allongée qui est ménagée dans la paroi latérale du cylindre de guidage et qui s'étend parallèlement à l'axe de ce dernier. On comprend que c'est le ressort de compression précité qui est chargé de pousser l'extrémité libre du pène en question dans les encoches respectives de la tige de verrouillage, cependant que le tenon coopérant avec une lumière allongée empêche le pène de tourner dans son cylindre de guidage et délimite sa course axiale. On notera également que cette solution permet de rattraper automatiquement les jeux et l'usure du pène et de la tige de verrouillage, ainsi que de corriger d'éventuels défauts de linéarité de cette dernière, ces défauts pouvant résulter par exemple de flambages de la tige.As regards the bolt device specified above, it advantageously comprises a guide cylinder mounted on the sliding body perpendicular to the sliding axis thereof, a bolt proper which is slidably mounted inside the guide cylinder and the free end of which has dimensions allowing it to penetrate into the transverse notches of the locking rod, a compression spring inserted between the bottom of the guide cylinder and the bolt itself and a tenon integral with the bolt itself said and sliding in an elongated lumen which is formed in the side wall of the guide cylinder and which extends parallel to the axis of the latter. It is understood that it is the aforementioned compression spring which is responsible for pushing the free end of the bolt in question into the respective notches of the locking rod, while the pin cooperating with an elongated light prevents the bolt from rotating in its guide cylinder and defines its axial travel. It will also be noted that this solution makes it possible to automatically make up for the play and wear of the bolt and of the locking rod, as well as to correct possible linearity defects of the latter, these defects being able to result for example from buckling of the rod. .
De préférence, les moyens spécifiés plus haut qui permettent de faire tourner la tige de verrouillage selon l'invention autour de son axe comprennent un embout prismatique qui fait saillie à l'une des extrêmités de cette tige et dont les arêtes sont parallèles à l'axe de cette dernière, ainsi qu'une clef de manoeuvre terminée par une empreinte femelle reproduisant en creux la forme en section transversale de l'embout prismatique précité. Cet embout dont la section transversale est par exemple triangulaire peut être réalisé d'un seul tenant avec la tige de verrouillage, mais il peut aussi faire partie d'un barillet monté de façon interchangeable à l'une des extrêmités de celle-ci, de sorte qu'il est aisé de changer périodiquement de modèle de clef, ce qui diminue le risque d'utilisation par des personnes non autorisées.Preferably, the means specified above which make it possible to rotate the locking rod according to the invention about its axis comprise a prismatic endpiece which projects at one of the ends of this rod and whose edges are parallel to the axis of the latter, as well as an operating key terminated by a female imprint reproducing in hollow the cross-sectional shape of the aforementioned prismatic tip. This end piece whose cross section is for example triangular can be made in one piece with the locking rod, but it can also be part of a barrel interchangeably mounted at one of its ends, so that it is easy to periodically change the key model, which reduces the risk use by unauthorized persons.
Avantageusement, une plaque d'accès est montée fixe au-delà de l'embout prismatique de la tige de verrouillage, dans un plan perpendiculaire à l'axe de celle-ci, cette plaque d'accès étant munie dans le prolongement de la tige, d'une ouverture qui est destinée au passage de la clef de manoeuvre et dont la forme correspond à celle du pourtour extérieur de la clef en question. Ainsi, la tige de verrouillage ne peut être actionnée que par une clef correspondant au modèle en service, non seulement par son empreinte intérieure, mais aussi par son contour extérieur. En outre, une telle plaque d'accès protège largement le dispositif de verrouillage contre l'intrusion d'outils qui tenteraient de le forcer.Advantageously, an access plate is fixedly mounted beyond the prismatic end piece of the locking rod, in a plane perpendicular to the axis of the latter, this access plate being provided in the extension of the rod. , an opening which is intended for the passage of the operating key and whose shape corresponds to that of the outer periphery of the key in question. Thus, the locking rod can only be actuated by a key corresponding to the model in service, not only by its internal imprint, but also by its external contour. In addition, such an access plate largely protects the locking device against the intrusion of tools which would try to force it.
Si en outre, selon une forme de réalisation très avantageuse, le contour extérieur de la clef de manoeuvre, lorsque celle-ci coiffe l'embout prismatique de la tige de verrouillage, n'est dans l'alignement exact de l'ouverture ménagée dans la plaque d'accès que pour une seule des positions angulaires prédéterminées de la tige de verrouillage, et donc du corps coulissant, on ne pourra retirer la clef à travers l'ouverture de la plaque d'accès que si l'on a préalablement placé la tige de verrouillage dans la position prédéterminée qui autorise cette opération. Dans le cas d'une borne de voirie à deux positions, on choisit, bien entendu, pour unique position angulaire permettant l'extraction de la clef, celle qui correspond à la position haute de la borne, de sorte que l'utilisateur ne pourra récupérer sa clef que s'il a pris soin de remettre la borne dans cette position haute.If in addition, according to a very advantageous embodiment, the outer contour of the operating key, when it covers the prismatic end of the locking rod, is not in exact alignment with the opening in the access plate only for one of the predetermined angular positions of the locking rod, and therefore of the sliding body, the key can only be removed through the opening of the access plate if one has previously placed the locking rod in the predetermined position which authorizes this operation. In the case of a road terminal with two positions, of course, the only angular position allowing the extraction of the key is chosen, that which corresponds to the upper position of the terminal, so that the user cannot recover his key only if he has taken care to put the terminal in this high position.
L'association de cette dernière caractéristique avantageuse des diverses formes que l'on peut donner à l'empreinte de la clef et à son contour extérieur, et des diverses positions angulaires relatives qui sont possibles pour la tige de verrouillage et pour l'ouverture de la plaque d'accès permet de multiplier presque à l'infini les combinaisons de confidentialité imaginables, ce qui conduit à une sécurité inégalée jusqu'alors.The association of this last advantageous characteristic of the various forms which can be given to the imprint of the key and to its external contour, and of the various relative angular positions which are possible for the locking rod and for the opening of the access plate makes it possible to multiply almost infinitely the combinations of confidentiality imaginable, which leads to security unmatched before.
La protection du dispositif selon l'invention contre les agents extérieurs comme les eaux de ruissellement, les poussières et le sable est avantageusement assurée grâce à une trappe à fermeture automatique qui est disposée au-dessus de la tige de verrouillage au niveau du sol.The protection of the device according to the invention against external agents such as runoff, dust and sand is advantageously ensured by means of a hatch with automatic closure which is arranged above the locking rod at ground level.
De préférence, la tige de verrouillage selon l'invention comprend une encoche de maintien et de rappel en position angulaire dont le fond est constitué par une pluralité de méplats, chacun de ceux-ci correspondant à l'une des positions angulaires prédéterminées que l'on veut maintenir et s'étendant parallèlement dans l'espace à la corde de l'encoche correspondante, et dans laquelle pénètre une branche d'un levier en L qui est rappelée élastiquement vers le fond de l'encoche et dont l'autre branche est articulée par son extrêmité sur un élément fixe. Cette sorte d'encliquetage assure le maintien de la tige de verrouillage dans chacune de ses positions angulaires qui correspond à l'une des positions prédéterminées du corps coulissant et aussi son rappel vers la position la plus proche.Preferably, the locking rod according to the invention comprises a notch for retaining and returning to the angular position, the bottom of which is constituted by a plurality of flats, each of these corresponding to one of the predetermined angular positions that the we want to maintain and extending parallel in space to the cord of the corresponding notch, and into which penetrates a branch of an L-shaped lever which is resiliently biased towards the bottom of the notch and the other branch of which is articulated by its end on a fixed element. This kind of latching ensures the maintenance of the locking rod in each of its angular positions which corresponds to one of the predetermined positions of the sliding body and also its return to the nearest position.
Quant au dispositif qui commande les déplacements du corps coulissant, c'est-à-dire par exemple de la borne de voirie, il pourrait s'agir du mécanisme pneumatique décrit dans le brevet français N° 86 05310 du 4 avril 1986, mais aussi d'un simple ressort que l'on comprime à la main en poussant sur la borne afin de l'amener en position basse, et qui se détend lorsque le dispositif de verrouillage selon l'invention permet à la borne de revenir à sa position haute.As for the device which controls the movements of the sliding body, that is to say for example of the road bollard, it could be the pneumatic mechanism described in French patent No. 86 05310 of April 4, 1986, but also a simple spring which is compressed by hand by pushing on the terminal in order to bring it to the low position, and which relaxes when the locking device according to the invention allows the terminal to return to its high position .
On constate d'après ce qui précède que les solutions proposées par la présente invention permettent d'atteindre complètement les buts qui étaient visés.It can be seen from the above that the solutions proposed by the present invention make it possible to completely achieve the aims which were aimed at.
Cela étant, la description qui va suivre, et qui ne présente aucun caractère limitatif, permettra de bien comprendre comment la présente invention peut être mise en pratique. Elle doit être lue en regard des dessins annexés, parmi lesquels :

Pour expliquer le mode de fonctionnement du dispositif de verrouillage qui vient d'être décrit, on supposera que la borne rétractable (1) et le chariot de translation (2) se trouvent dans leur position haute et que la position angulaire de la tige de verrouillage (7) est telle que l'encoche supérieure (17a) de cette tige soit dirigée vers le pène (13), comme cela est représenté sur la combinaison des figures 2 et 3, de sorte que l'extrêmité libre de ce pène y pénètre sous l'effet du ressort (14). Si l'on essayait alors de déplacer verticalement la borne de voirie (1), rien ne se passerait, puisque le pène (13) solidaire de la borne (1) par l'intermédiaire du chariot de translation (2) et engagé dans l'encoche (17a) de la tige (7) empêche tout mouvement vertical de l'ensemble constitué par la borne (1) et le chariot de translation (2).To explain the operating mode of the locking device which has just been described, it will be assumed that the retractable terminal (1) and the translation carriage (2) are in their high position and that the angular position of the locking rod (7) is such that the upper notch (17a) of this rod is directed towards the bolt (13), as shown in the combination of Figures 2 and 3, so that the free end of this bolt enters there under the effect of the spring (14). If we then tried to move the road terminal vertically (1), nothing would happen, since the bolt (13) secured to the terminal (1) via the translation carriage (2) and engaged in the 'notch (17a) of the rod (7) prevents any vertical movement of the assembly formed by the terminal (1) and the translation carriage (2).
Si l'utilisateur ouvre alors la trappe (30) et enfonce sa clef à travers l'ouverture (27) de la plaque d'accès (26), l'empreinte femelle de celle-ci vient coiffer l'embout prismatique (19) de la tige de verrouillage (7), comme on l'a dit plus haut. Il fait alors tourner sa clef d'un quart de tour dans le sens imposé par les butées (20) de la tige (7) et le mécanisme constitué par le levier (21), le ressort de traction (24) et les méplats (25) fait sauter la tige (7) dans son autre position extrême. Pendant ce temps, l'extrêmité libre du pène (13) glisse sur le fond cylindrique de l'encoche (17a) et le pène (13) est repoussé vers l'extérieur à l'encontre du ressort (14). Lorsqu'il est complètement sorti de l'encoche (17a), le chariot de translation (2) est libre de se déplacer vers le bas, sous l'effet de ses moyens de commande qui peuvent être tout simplement constitués par une poussée manuelle exercée sur la borne de voirie (1) à l'encontre d'un ressort de compression, l'extrémité libre du pène (13) glissant sur l'une des génératrices de la tige (7) jusqu'à ce qu'elle pénètre dans l'encoche inférieure (17b) sous l'effet du ressort (14), ce qui bloque la progression vers le bas du chariot de translation (2), et donc de la borne (1) qui se trouve alors en position rétractée. La remontée de l'ensemble formé par la borne (1) et le chariot de translation (2) est également empêchée par l'encliquetage du pène (13) dans l'encoche (17b) de la tige de verrouillage (7).If the user then opens the hatch (30) and pushes his key through the opening (27) of the access plate (26), the female imprint of the latter comes to cover the prismatic endpiece (19) of the locking rod (7), as mentioned above. He then turns his key a quarter turn in the direction imposed by the stops (20) of the rod (7) and the mechanism constituted by the lever (21), the tension spring (24) and the flats ( 25) causes the rod (7) to jump to its other extreme position. During this time, the free end of the bolt (13) slides on the cylindrical bottom of the notch (17a) and the bolt (13) is pushed outwards against the spring (14). When it is completely out of the notch (17a), the translation carriage (2) is free to move downward, under the effect of its control means which can simply consist of a manual push exerted on the road terminal (1) against a compression spring, the free end of the bolt (13) sliding on one of the generatrices of the rod (7) until it enters the lower notch (17b) under the effect of the spring (14), which blocks the downward progression of the translation carriage (2), and therefore of the terminal (1) which is then in the retracted position. The assembly of the assembly formed by the terminal (1) and the translation carriage (2) is also prevented by the latching of the bolt (13) in the notch (17b) of the locking rod (7).
L'utilisateur peut alors faire passer son véhicule, mais si par négligence, il laisse les choses en l'état, il ne pourra pas récupérer sa clef qui est bloquée par son ergot latéral (28) au-dessous de la plaque d'accès (26) et il ne pourra la ressortir que moyennant un quart de tour en sens inverse imprimé à la clef, et donc à la tige de verrouillage (7) par l'intermédiaire de l'embout prismatique (19). Cette opération s'accompagne de la poussée du pène (13) hors de l'encoche inférieure (17b) de la tige (7), du glissement de l'extrêmité libre de celui-ci le long d'une génératrice de la tige (7), sous l'effet du mécanisme de commande qui tend à faire remonter le chariot de translation (2) et la borne (1) et donc le pène (13) qui en est solidaire, et de son encliquetage dans l'encoche supérieure (17a) de la tige (7) qui se trouve alors sur son trajet.The user can then pass his vehicle, but if negligently, he leaves things as they are, he will not be able to recover his key which is blocked by his lateral lug (28) below the access plate (26) and it can only come out again by means of a quarter turn in the opposite direction printed on the key, and therefore on the locking rod (7) by means of the prismatic endpiece (19). This operation is accompanied by the push of the bolt (13) out of the lower notch (17b) of the rod (7), the sliding of the free end of the latter along a generatrix of the rod ( 7), under the effect of the control mechanism which tends to raise the translation carriage (2) and the terminal (1) and therefore the bolt (13) which is integral therewith, and of its snapping into the upper notch (17a) of the rod (7) which is then in its path.
L'utilisateur peut maintenant retirer sa clef dont l'ergot (28) est aligné sur le cran de passage (29) de la plaque d'accès (26) et le système est revenu à sa position initiale où la borne (1) est en saillie au-dessus du sol pour empêcher le passage.The user can now remove his key, the lug (28) of which is aligned with the passage notch (29) of the access plate (26) and the system has returned to its initial position where the terminal (1) is protruding above the ground to prevent passage.
IL est clair que, sans sortir du cadre de la présente invention, de nombreuses modifications pourraient être apportées à la forme de réalisation qui vient d'être décrite. C'est ainsi que ce dispositif pourrait comporter un nombre de positions de verrouillage supérieur à deux, en prévoyant un nombre correspondant d'encoches (17) situées aux endroits voulus le long de la tige (7) et décalées angulairement les unes par rapport aux autres d'un angle tel que le pène (13), lorsqu'il a quitté une encoche du fait de la rotation de la tige (7) et qu'il glisse sur une génératrice de cette dernière, rencontre nécessairement l'encoche visée dans laquelle il peut alors venir s'encliqueter.It is clear that, without departing from the scope of the present invention, numerous modifications could be made to the embodiment which has just been described. Thus, this device could include a number of locking positions greater than two, by providing a corresponding number of notches (17) located at the desired locations along the rod (7) and angularly offset relative to the others at an angle such as the bolt (13), when it has left a notch due to the rotation of the rod (7) and it slides on a generator of the latter, necessarily meets the notch targeted in which it can then snap into place.
Dans le cas d'une borne de voirie, il serait alors possible de donner à celle-ci plusieurs positions en hauteur. Par ailleurs, l'embout prismatique (19) qui est destiné à être coiffé par la clef de manoeuvre C pourrait être, non point d'un seul tenant avec la tige (7), mais formé sur un barillet interchangeable. En outre, on pourrait utiliser d'autres mécanismes que l'équerre (20) pour limiter la course en rotation de la tige de verrouillage (7), comme par exemple un doigt fixe pénétrant dans une gorge annulaire ménagée sur 90° dans cette tige (7). Le montage de cette dernière dans la cage (4) pourrait faire appel à d'autres dispositifs qu'à la crapaudine (8) et au palier (9), et, par ailleurs, le contour de l'ouverture (27) de la plaque d'accès (26) pourrait différer de celui représenté sur la figure 9. On notera enfin que, dans le cas où le nombre des positions de verrouillage est supérieur à deux, le nombre de méplats (25) ménagés dans l'encoche (23) de la tige (7) en vue de l'encliquetage de cette dernière dans chacune de ses positions devrait être égal à celui des positions de verrouillage, chaque méplat étant parallèle dans l'espace à la corde de l'encoche (17) correspondante.In the case of a road terminal, it would then be possible to give it several height positions. Furthermore, the prismatic endpiece (19) which is intended to be capped by the operating key C could be, not in one piece with the rod (7), but formed on an interchangeable barrel. In addition, we could use other mechanisms than the bracket (20) to limit the rotational travel of the locking rod (7), such as a fixed finger penetrating into an annular groove formed on 90 ° in this rod (7). The assembly of the latter in the cage (4) could call on other devices only to the clamp (8) and to the bearing (9), and, moreover, the outline of the opening (27) of the access plate (26) could differ from that shown in FIG. finally note that, in the case where the number of locking positions is greater than two, the number of flats (25) formed in the notch (23) of the rod (7) for the purpose of latching the latter in each of its positions should be equal to that of the locking positions, each flat being parallel in space to the chord of the corresponding notch (17).
