Description

L'invention concerne un agencement à dispositif pivotant entre deux positions, tel qu'un agencement de barrière pivotant entre une position d'interdiction de l'accès à une zone réservée et une position de dégagement de l'accès, notamment agencement de barrière de parking pour véhicule automobile, du type comprenant un dispositif de barrière à bras pivotant comportant au moins un bras et avantageusement un dispositif à deux bras en forme d'arceau, un dispositif d'entraînement en pivotement dudit dispositif de barrière et des moyens d'actionnement de ce dispositif d'entraînement.The invention relates to an arrangement with a device pivoting between two positions, such as a barrier arrangement pivoting between a position preventing access to a reserved area and a position for releasing access, in particular a barrier arrangement parking lot for a motor vehicle, of the type comprising a barrier device with pivoting arm comprising at least one arm and advantageously a device with two arms in the form of a hoop, a device for pivoting said barrier device and actuating means of this drive device.

On connaît déjà des agencements de barrière de ce type. Tous présentent l'inconvénient majeur que le dispositif d'entraînement présente une structure complexe et encombrante comportant par exemple une tige filetée entraînée en rotation par un moteur électrique et engrènant un écrou non rotatif qui, sous l'effet de la rotation de la tige, effectue un mouvement axial rectiligne de va-et-vient, qui provoque le pivotement de la barrière, par l'intermédiaire d'une tringle articulée à l'écrou et au dispositif de barrière.Barrier arrangements of this type are already known. All have the major drawback that the drive device has a complex and bulky structure comprising for example a threaded rod driven in rotation by an electric motor and engaging a non-rotating nut which, under the effect of the rotation of the rod, performs a rectilinear axial movement back and forth, which causes the pivoting of the barrier, by means of a rod articulated to the nut and to the barrier device.

La présente invention a pour objectif de proposer un agencement qui remédie aux inconvénients de l'état de la technique.The object of the present invention is to propose an arrangement which overcomes the drawbacks of the state of the art.

Pour atteindre ce but, l'agencement selon l'invention est caractérisé en ce que le dispositif d'entraînement comporte un levier à deux bras de longueur différente, qui est monté pivotant autour d'un dispositif pivot fixe, le bras le plus court est relié au dispositif de barrière pour faire pivoter celui-ci lorsque le levier pivote autour dudit dispositif pivot fixe et en ce que le dispositif d'actionnement agit sur l'extrémité du bras le plus long.To achieve this object, the arrangement according to the invention is characterized in that the drive device comprises a lever with two arms of different length, which is pivotally mounted around a fixed pivot device, the shortest arm is connected to the barrier device to pivot the latter when the lever pivots around said fixed pivot device and in that the actuating device acts on the end of the longest arm.

Selon une caractéristique avantageuse de l'invention, le dispositif d'entraînement comporte des moyens pour impartir au levier à deux bras une composante de mouvement axial en direction de l'axe de pivotement du dispositif de barrière, qui se superpose au mouvement de pivotement du levier, de façon que le pivotement du dispositif de barrière s'effectue tout d'abord principalement sous l'effet du pivotement du levier et ensuite sous l'effet dudit mouvement axial de celui-ci.According to an advantageous characteristic of the invention, the drive device comprises means for imparting to the two-armed lever a component of axial movement in the direction of the pivot axis of the barrier device, which is superimposed on the pivoting movement of the lever, so that the pivoting of the barrier device takes place firstly under the effect of the pivoting of the lever and then under the effect of said axial movement thereof.

Selon une autre caractéristique avantageuse de l'invention, le dispositif de barrière comporte au niveau de son axe de pivotement un organe formant came sur lequel agit l'extrémité du bras court du levier d'entraînement en pivotement, et le dispositif pivot est réalisé sous forme d'un dispositif prenant appui sur une surface fixe par une zone de contact avantageusement linéaire et perpendiculaire à l'axe du levier, cette zone de contact étant déplaçable sur la surface de support, dans la direction axiale du levier.According to another advantageous characteristic of the invention, the barrier device comprises at its pivot axis a cam member on which acts the end of the short arm of the pivoting drive lever, and the pivot device is produced under form of a device supported on a fixed surface by an advantageously linear contact area and perpendicular to the axis of the lever, this contact area being movable on the support surface, in the axial direction of the lever.

Selon une autre caractéristique avantageuse de l'invention, le dispositif pivot comporte au moins un galet dont l'axe s'étend perpendiculairement à la direction longitudinale du levier et qui est en contact de roulement avec la surface de support.According to another advantageous characteristic of the invention, the pivot device comprises at least one roller whose axis extends perpendicular to the longitudinal direction of the lever and which is in rolling contact with the support surface.

Selon encore une autre caractéristique avantageuse de l'invention, l'extrémité du bras long du levier est en appui sur une surface inclinée par rapport à l'axe du levier de façon qu'un mouvement de pivotement de l'extrémité de ce bras dans le sens d'entraînement en pivotement du dispositif de barrière vers cette position de blocage produise le déplacement axial précité du levier.According to yet another advantageous characteristic of the invention, the end of the long arm of the lever is supported on a surface inclined with respect to the axis of the lever so that a pivoting movement of the end of this arm in the direction of pivoting drive of the barrier device towards this locking position produces the above-mentioned axial displacement of the lever.

Selon encore une autre caractéristique avantageuse de l'invention, le dispositif d'actionnement du levier comporte un moteur électrique pourvu d'un axe rotatif dont le mouvement angulaire provoque le pivotement du levier.According to yet another advantageous characteristic of the invention, the lever actuation device comprises an electric motor provided with a rotary axis whose angular movement causes the lever to pivot.

Selon encore une autre caractéristique avantageuse de l'invention, le dispositif d'actionnement comporte un électro-aimant pourvu d'un solénoïde dont le déplacement provoque le pivotement du levier.According to yet another advantageous characteristic of the invention, the actuating device comprises an electromagnet provided with a solenoid whose displacement causes the lever to pivot.

L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels:

L'invention sera décrite ci-après, à titre d'exemple, dans son application à un agencement de barrière pour zone de parking pour véhicule automobile.The invention will be described below, by way of example, in its application to a barrier arrangement for a parking area for a motor vehicle.

La figure 1 montre que l'agencement de barrière selon l'invention se présente sous forme d'un boîtier plat parallèlépipédique A comportant un couvercle 1 et une plaque de fond 2 et auquel est articulé un dispositif de barrière B. Le boîtierest implanté dans le sol de la zone de parking, la surface supérieure étant dégagée et au niveau du sol.FIG. 1 shows that the barrier arrangement according to the invention is in the form of a flat parallelepipedal housing A comprising a cover 1 and a bottom plate 2 and to which a barrier device B is articulated. The housing is located in the parking area floor, the upper surface being clear and at ground level.

Comme il ressort des figures 2 à 4, le dispositif de barrière 3 est réalisé sous forme d'un arceau qui est monté pivotant, à l'aide d'un axe 3 dans des paliers 4 fixés sur la plaque de fond 2, de façon à être pivotants entre une position escamotée dans le sol et une position de barrage dans laquelle il bloque l'accès à une zone de parking réservé. L'axe 3 de l'arceau B comporte dans sa partie axialement médiane une partie cylindrique excentrée 5 qui constitue une came d'actionnement en pivotement de l'arceau.As can be seen from FIGS. 2 to 4, the barrier device 3 is produced in the form of a hoop which is pivotally mounted, by means of a pin 3 in bearings 4 fixed on the bottom plate 2, so to be pivoting between a retracted position in the ground and a barrier position in which it blocks access to a reserved parking area. The axis 3 of the arch B has in its axially middle part an eccentric cylindrical part 5 which constitutes an actuating cam for pivoting the hoop.

L'agencement comporte aussi un dispositif d'entraînement en pivotement de l'arceau, qui comporte essentiellement un levier à deux bras 6 de longueurs différentes qui s'étend longitudinalement dans le boîtier. Ce levier comporte un premier bras plus court 7 qui coopère avec l'excentrique 5 de l'axe de pivotement de l'arceau B et un bras long 8 dont l'extrémité porte un dispositif à galets 9 dont les deux galets 10 sont montés sur un axe commun perpendiculaire au sens longitudinal de levier, de part et d'autre de celui-ci. Les galets sont en contact de roulement avec une surface de rampe inclinée 12 monté sur le fond 2 qui présente un angle d'inclinaison a par rapport à une ligne perpendiculaire au fond du boiter 2, qui est relativement faible. Cette surface de rampe est inclinée faiblement dans le sens inverse dans sa zone proche de fond pour produire un effet de blocage du levier lorsque celui-ci occupe sa position enfoncée représentée à la figure 4.The arrangement also comprises a device for pivoting the hoop, which essentially comprises a lever with two arms 6 of different lengths which extends longitudinally in the housing. This lever comprises a first shorter arm 7 which cooperates with the eccentric 5 of the pivot axis of the hoop B and a long arm 8, the end of which carries a roller device 9, the two rollers 10 of which are mounted on a common axis perpendicular to the longitudinal direction of lever, on both sides of the latter. The rollers are in rolling contact with an inclined ramp surface 12 mounted on the bottom 2 which has an angle of inclination a relative to a line perpendicular to the bottom of the box 2, which is relatively small. This ramp surface is inclined slightly in the opposite direction in its region near the bottom to produce a locking effect of the lever when the latter occupies its depressed position shown in FIG. 4.

Le levier 6 comporte un dispositif pivot 13 qui, dans l'exemple représenté, comporte deux galets 14 montés rotatifs sur un même axe perpendiculaire à l'axe du levier et situés de part et d'autre de ce dernier. La position axiale du dispositif pivot 13 est fixe sur le levier 6 car il détermine les deux bras 7 et 8 du levier. Ce dernier prend appui sur la surface supérieure de fond du boiter 2 par l'intermédiaire de ces galets 14. La position axiale du dispositif pivot 13 est variable en position axiale sur le levier 6, due à un évidement oblong 16 pratiqué dans le levier et dans lequel l'axe des deux galets 14 est déplaçable et arrêtable à l'aide de tout moyen connu approprié. Le bras court 7 du levier 6 porte sur sa surface supérieure d'appui de l'exentrique 5 de l'axe de pivotement 3 de l'arceau B un épaulement 19 formé par la face frontale d'une pièce rapportée 20 dont la position axiale sur le bras de levier 7 est réglable grâce à un évidement axial oblong 21 pratiqué dans la pièce 20, traversé par une vis de solidarisation par serrage 22.The lever 6 comprises a pivot device 13 which, in the example shown, comprises two rollers 14 rotatably mounted on the same axis perpendicular to the axis of the lever and located on either side of the latter. The axial position of the pivot device 13 is fixed on the lever 6 because it determines the two arms 7 and 8 of the lever. The latter is supported on the upper bottom surface of the box 2 by means of these rollers 14. The axial position of the pivot device 13 is variable in the axial position on the lever 6, due to an oblong recess 16 formed in the lever and in which the axis of the two rollers 14 can be moved and stopped using any suitable known means. The short arm 7 of the lever 6 carries on its upper bearing surface of the eccentric 5 of the pivot axis 3 of the hoop B a shoulder 19 formed by the front face of an insert 20 whose axial position on the lever arm 7 is adjustable thanks to an oblong axial recess 21 made in the part 20, crossed by a tightening screw 22.

Le dispositif d'actionnement du levier6 comprend essentiellement, dans l'exemple de réalisation représenté, un moteur 25 à arbre rotatif 26. Sur l'extrémité libre de ce dernier est monté solidaire en rotation à une de ses extrémités, un bras radial 27 dont l'extrémité libre porte un tourillon sur lequel est monté librement en rotation un galet 28 qui s'étend parallèlement à l'axe 26 et vient en appui sur la surface supérieure de l'extrémité du bras long 8 du levier 6, dans la partie proche de la rampe 12. Pour compléter la description de l'agencement de barrière selon l'invention, on constate qu'on peut prévoir sur le bras long 8 du levier 6 des contrepoids indiqués schématiquement en 30 qui sont adaptés pour que la force d'actionnement du levier 6 en vue de son pivotement puisse être très faible. Pour pouvoir ajuster l'ensemble à son état d'équilibre, la position axiale du contrepoids 30 pourrait être réglable sur le bras de levier 8.The lever actuation device 6 essentially comprises, in the embodiment shown, a motor 25 with a rotary shaft 26. On the free end of the latter is mounted rotatably mounted at one of its ends, a radial arm 27 of which the free end carries a journal on which a roller 28 is freely mounted in rotation which extends parallel to the axis 26 and bears on the upper surface of the end of the long arm 8 of the lever 6, in the part close to the ramp 12. To complete the description of the barrier arrangement according to the invention, it can be seen that we can provide on the long arm 8 of the lever 6 counterweights indicated diagrammatically at 30 which are adapted so that the force d actuation of the lever 6 for its pivoting can be very low. To be able to adjust the assembly to its equilibrium state, the axial position of the counterweight 30 could be adjustable on the lever arm 8.

Le dispositif d'alimentation en énergie électrique est enfermé dans le boîtier et comporte avantageusement une batterie rechargeable, schématiquement indiquée en 31 et un capteur d'énergie solaire indiqué en 32 sur la figure 1.The electrical energy supply device is enclosed in the housing and advantageously comprises a rechargeable battery, diagrammatically indicated at 31 and a solar energy sensor indicated at 32 in FIG. 1.

L'agencement de barrière de parking selon l'invention peut être télécommandé, par exemple à l'aide d'une télécommande radio à distance. Le dispositif électrique comporte à cette fin un récepteur (non représenté) qui est également alimenté en énergie électrique à partir du capteur solaire de façon à être en service par exemple une seconde sur trois. A cette fin il pourrait être alimenté en énergie électrique pendant une seconde tous les trois secondes. L'énergie produite par le capteur solaire pendant les trois secondes où le récepteur est hors service, pourrait être utilisée pour recharger la batterie constituant la source d'énergie électrique du moteur 25.The parking barrier arrangement according to the invention can be remote-controlled, for example using a radio remote control. To this end, the electrical device comprises a receiver (not shown) which is also supplied with electrical energy from the solar collector so as to be in service for example every second out of three. To this end it could be supplied with electrical energy for one second every three seconds. The energy produced by the solar collector during the three seconds when the receiver is out of service, could be used to recharge the battery constituting the electric energy source of the motor 25.

Le circuit d'alimentation en énergie électrique du moteur comporte un fusible à deux états stables, qui est connu en soi et fonctionne comme un interrupteur qui est fermé à l'état de fonctionnement normal du moteur et s'ouvre lorsque le courant d'excitation du moteur dépasse une valeur de seuil prédéterminée. Cette valeur de seuil est détectable sous forme d'un échauffement au-delà d'une température prédéterminée produite par le courant d'excitation du moteur. Un tel échauffement avec interruption du circuit d'alimentation en énergie électrique du moteur se produira lorsque l'arceau, lors de son mouvement de pivotement, rencontre un obstacle lui opposant une force de réaction dépassant une valeur prédéterminée. Le fusible bi-stable, qui vient d'être décrit et est monté dans le circuit d'alimentation en énergie du moteur 25 accomplit en outre la fonction de butée de fin de course du moteur. En effet, lorsque le levier occupe la position représentée à la figure 4, le mouvement angulaire de l'arbre rotatif 26 du moteur 25 s'arrête, ce que le moteur 25 détecte sous forme d'un couple de réaction dépassant la valeur de seuil prédéterminée susmentionnée et ce qui provoque l'ouverture du fusible interrupteur. Comme le montre la figure 3, lorsque l'arceau occupe sa position escamotée, le galet 28 du dispositif d'actionnement du levier porte contre la surface interne du boîtier. Ainsi lorsque le levier 6 revient à partir de sa position de relèvement de l'arceau (figure 4) dans la position escamotée, le mouvement angulaire de l'arbre 26 du moteur 25 est arrêté lorsque le galet 28 vient en appui contre la surface interne du boîtier, ce qui provoque à nouveau l'ouverture du fusible interrupteur en raison de l'échauffement dû à l'augmentation du couple de réaction qu'oppose le couvercle au mouvement angulaire de l'arbre de sortie 26 du moteur.The electrical power supply circuit of the motor comprises a fuse with two stable states, which is known per se and functions as a switch which is closed in the normal operating state of the motor and opens when the excitation current of the motor exceeds a predetermined threshold value. This threshold value is detectable in the form of overheating beyond a predetermined temperature produced by the excitation current of the motor. Such heating with interruption of the electric power supply circuit of the motor will occur when the hoop, during its pivoting movement, encounters an obstacle opposing a reaction force exceeding a predetermined value. The bi-stable fuse, which has just been described and is mounted in the power supply circuit of the motor 25 furthermore fulfills the function of end stop of the motor. In fact, when the lever occupies the position shown in FIG. 4, the angular movement of the rotary shaft 26 of the motor 25 stops, which the motor 25 detects in the form of a reaction torque exceeding the threshold value above and which causes the fuse switch to open. As shown in Figure 3, when the hoop occupies its retracted position, the roller 28 of the lever actuating device bears against the internal surface of the housing. Thus when the lever 6 returns from its position for raising the hoop (FIG. 4) in the retracted position, the angular movement of the shaft 26 of the motor 25 is stopped when the roller 28 comes to bear against the internal surface. of the housing, which again causes the opening of the switch fuse due to the heating due to the increase in the reaction torque that opposes the cover to the angular movement of the output shaft 26 of the motor.

On décrira ci-après brièvement le fonctionnement de l'agencement de barrière selon l'invention, qui vient d'être décrit et est représenté aux figures qui dans son principe ressort déjà de ce qui précède.The operation of the barrier arrangement according to the invention will be briefly described below. which has just been described and is shown in the figures which in principle already emerge from the above.

Lorsque le conducteur du véhicule automobile, qui est autorisé à stationner son véhicule sur l'aire de parking qu'équipe l'agencement selon l'invention, s'approche de cette zone, il émet à l'aide de son appareil de télécommande un signal dont la durée doit être suffisamment longue pour coïncider avec une période pendant laquelle le récepteur est alimenté en énergie à partir du capteur solaire. Etant donné que dans l'exemple représenté le récepteur est alimenté pendant une seconde sur trois, le conducteur est sûr que le récepteur reçoit le signal émis par l'appareil de télécommande si la durée d'actionnement de cet appareil dépasse la durée de quatre secondes. En réponse à la réception de ce signal de télécommande, le récepteur produit un signal entraînant l'alimentation en énergie électrique du moteur à partir de la batterie. Le moteur sera ainsi alimenté en énergie pour qu'il puisse provoquer le pivotement du levier 6 de sa position de relèvement de l'arceau, représenté à la figure 4 dans la position indiquée à la figure 3 dans laquelle l'arceau dégage l'accès à l'aire de parking. Comme il a été décrit plus haut, dans cette position le fusible interrupteur ouvre le circuit d'alimentation du moteur. Si après le refroidissement le fusible interrupteur ferme à nouveau le circuit d'alimentation, l'alimentation du moteur n'est pas reprise sans nouveau signal préalable en provenance du récepteur. Le même cycle d'opération lorsque le conducteur autorisé souhaite plus tard de commander le relèvement de l'arceau de barrière, il actionnera le mouvement de pivotement approprié s'effectuera à la suite d'un signal de télécommande approprié jusqu'à l'ouverture du circuit d'excitation du moteur quand le levier atteint la position représentée à la figure 4. Le levier est bloqué dans cette position par l'action concomittante de la partie de verrouillage 17 de la rampe 12 et l'arrêt de l'arbre moteur dans la position angulaire de fin de course.When the driver of the motor vehicle, who is authorized to park his vehicle in the parking area provided by the arrangement according to the invention, approaches this area, he emits using his remote control device a signal whose duration must be long enough to coincide with a period during which the receiver is supplied with energy from the solar collector. Since in the example shown the receiver is powered for one second out of three, the driver is sure that the receiver receives the signal emitted by the remote control device if the duration of actuation of this device exceeds the duration of four seconds . In response to the reception of this remote control signal, the receiver produces a signal causing the electric power supply to the motor from the battery. The motor will thus be supplied with energy so that it can cause the lever 6 to pivot from its hoop lifting position, shown in FIG. 4, in the position indicated in FIG. 3 in which the hoop clears the access. at the parking area. As described above, in this position the switch fuse opens the motor supply circuit. If after cooling the switch fuse closes the supply circuit again, the motor supply is not resumed without a new signal from the receiver. The same operating cycle when the authorized driver wishes later to control the raising of the barrier arch, he will activate the appropriate pivoting movement will be carried out following an appropriate remote control signal until the opening of the motor excitation circuit when the lever reaches the position shown in FIG. 4. The lever is locked in this position by the concomitant action of the locking part 17 of the ramp 12 and the stopping of the motor shaft in the angular end position.

Si pendant un mouvement de pivotement l'arceau rencontre un obstacle sur sa course, il est arrêté immédiatement dans sa position de pivotement sous l'effet du fusible interrupteur. En réponse à un nouveau signal de télécommande, le moteur tentera de ramener l'arceau dans la position de départ. Si pendant ce mouvement l'arceau est opposé à un autre obstacle, il s'arrête immédiatement et un nouveau signal de télécommande tentera de ramener l'arceau dans la position visée initialement. Si l'obstacle initial est toujours présent ou si au cours de cette course un autre obstacle s'oppose à l'arceau, il en résulte à nouveau l'arrêt immédiat du mouvement de pivotement de l'arceau. L'organigramme de la figure 5 illustre ce qui vient d'être décrit et la logique de commande du dispositif électrique de l'agencement selon l'invention, qui en est la cause.If, during a pivoting movement, the roll bar encounters an obstacle in its course, it is immediately stopped in its pivoting position under the effect of the switch fuse. In response to a new remote control signal, the motor will attempt to return the roll bar to the starting position. If during this movement the arch is opposed to another obstacle, it immediately stops and a new remote control signal will try to bring the arch back to the position originally intended. If the initial obstacle is still present or if during this race another obstacle opposes the arch, this again results in the immediate stopping of the pivoting movement of the arch. The flowchart of Figure 5 illustrates what has just been described and the control logic of the electrical device of the arrangement according to the invention, which is the cause.

Après la description de la structure de l'agencement de barrière selon l'invention, de son fonctionnement et, à travers celui-ci, du circuit de commande de l'agencement, on comprend aisément les avantages que procure la présente invention. Ces avantages résident notamment dans la structure très simple et ex- trêment peu encombrante de cet agencement. En raison de la composante de déplacement axial du levier, qui se superpose au mouvement de pivotement, l'angle de pivotement peut être maintenu à une valeur relativement faible, ce qui réduit la hauteur du boîtier à une valeur très limitée. L'utilisation du levier, le cas échéant équipée d'un contrepoids, permet de réduire à une valeur relativement faible la force nécessaire pour l'actionnement en pivotement du levier. En raison de ce fait, le moteur consomme peu d'énergie et l'agencement peut être entièrement autonome, lorsque l'on ajoute le capteur d'énergie solaire. Grâce à l'utilisation du fusible interrupteur à deux états, l'agencement selon l'invention ne nécessite pas de moyens de butée de fin de course particulières et d'arrêt spécifique en cas d'obstacle. Toutes ces fonctions sont accomplies par ce fusible interrupteur monté dans le circuit d'alimentation du moteur.After describing the structure of the barrier arrangement according to the invention, its operation and, through it, the control circuit of the arrangement, it is easy to understand the advantages which the present invention provides. These advantages reside in particular in the very simple and extremely space-saving structure of this arrangement. Due to the axial displacement component of the lever, which is superimposed on the pivoting movement, the pivoting angle can be kept at a relatively small value, which reduces the height of the housing to a very limited value. The use of the lever, if necessary equipped with a counterweight, makes it possible to reduce the force required for pivoting actuation of the lever to a relatively low value. Due to this fact, the motor consumes little energy and the arrangement can be completely autonomous, when adding the solar energy collector. Thanks to the use of the two-state switch fuse, the arrangement according to the invention does not require any particular end-of-travel stop means and specific stop means in the event of an obstacle. All these functions are accomplished by this switch fuse mounted in the motor supply circuit.

Bien entendu de diverses modifications peuvent être apportées à l'agencement qui vient d'être décrit et est représenté. Ainsi le moteur électrique pourrait être remplacé par tout autre dispositif d'actionnement approprié, tel que par exemple un électro-aimant par exemple à solénoïde à deux positions stables. On comprend aisément que l'agencement peut également fonctionner sur commande manuelle, en cas d'absence ou défaillance du dispositif d'actionnement moteur.Of course, various modifications can be made to the arrangement which has just been described and is shown. Thus the electric motor could be replaced by any other suitable actuation device, such as for example an electromagnet, for example with a solenoid with two stable positions. It is easily understood that the arrangement can also operate on manual control, in the event of the absence or failure of the motor actuation device.

Pour faire en sorte que l'arceau, dans sa position relevée, s'efface lorsqu'une force supérieure à un seuil prédéterminé agit sur celui-ci, on pourrait relier l'arceau à chaque extrémité de ces bras pivotants à l'axe 3 à l'aide d'une goupille auto-séquante dont le diamètre sera dimensionné en fonction de ce seuil.To ensure that the arch, in its raised position, disappears when a force greater than a predetermined threshold acts on it, we could connect the arch at each end of these pivoting arms to the axis 3 using a self-sequencing pin whose diameter will be sized according to this threshold.

L'invention est applicable de façon générale à tous les agencements comportant un levier et dispositif pivotant. Par exemple l'invention est applicable à des agencements de type monte-charge comportant un dispositif tel qu'une plate-forme qui est amenée à se déplacer entre une position abaissée et une position relevée. Dans ce cas, la plate-forme sera articulée à l'extrémité libre du dispositif à bras pivotant B et à ce dernier sera associé un deuxième bras ou dispositif pivotant parallèle qui forme avec le premier un parallélogramme assurant que la plate-forme exécute un mouvement en translation. L'invention pourrait aussi être appliquée à une benne de camion.The invention is generally applicable to all arrangements comprising a lever and pivoting device. For example, the invention is applicable to arrangements of the freight elevator type comprising a device such as a platform which is caused to move between a lowered position and a raised position. In this case, the platform will be articulated at the free end of the device with pivoting arm B and to the latter will be associated a second arm or parallel pivoting device which forms with the first a parallelogram ensuring that the platform performs a movement. in translation. The invention could also be applied to a truck tipper.
