Description

On sait que sous le nom de "obturateur de parking" on désigne habituellement des dispositifs scellés dans le sol en avant d'un emplacement de parking afin d'interdire à tout véhicule non autorisé d'accéder audit emplacement ou de quitter celui-ci.We know that under the name of "parking shutter" we usually designate devices sealed in the ground in front of a parking space in order to prohibit any unauthorized vehicle from accessing or leaving said location.

Les obturateurs connus comprennent généralement un poteau dont la base est articulée sur un bâti fixé dans le sol, de manière à pouvoir affecter soit une position basse escamotée pour laquelle il permet la circulation d'un véhicule, soit une position verticale pour laquelle il fait obstacle à une telle circulation. A ce poteau escamotable sont associés des moyens de verrouillage à serrure de commande, agencés pour immobiliser ledit poteau à la position verticale, et éventuellement, à la position basse horizontale.Known shutters generally comprise a post whose base is articulated on a frame fixed in the ground, so as to be able to affect either a low retracted position for which it allows the movement of a vehicle, or a vertical position for which it obstructs to such traffic. Associated with this retractable post are locking means with a control lock, arranged to immobilize said post in the vertical position, and possibly in the low horizontal position.

L'utilisation d'un tel obturateur implique un processus quelque peu contraignant. Le conducteur qui désire garer son véhicule doit immobiliser celui-ci devant l'emplacement considéré, descendre, manoeuvrer le dispositif pour escamoter le poteau, remonter dans le véhicule pour occuper l'emplacement, le garer, et manoeuvrer à nouveau le dispositif pour ramener et bloquer le poteau à la position verticale. Une manoeuvre aussi complexe doit être effectuée lorsque le conducteur entend quitter l'emplacement de parking et interdire à tout tiers d'occuper celui-ci jusqu'à son retour.The use of such a shutter involves a somewhat restrictive process. The driver who wishes to park his vehicle must immobilize it in front of the location in question, descend, maneuver the device to retract the post, climb back into the vehicle to occupy the location, park it, and maneuver the device again to bring back and lock the post in the vertical position. Such a complex maneuver must be carried out when the driver intends to leave the parking space and prohibit any third party from occupying it until his return.

Aussi, en vue de simplifier l'utilisation des obturateurs de parking, a-t-on proposé des dispositifs motorisés à actionnement électrique, susceptibles d'être commandés à distance par émission de rayonnements infra-rouges, à la manière des portails, barrières ou similaires. Les constructions proposées font appel à un moto-réducteur qui est logé dans le bâti ou socle scellé dans le sol et qui est agencé pour assurer le pivotement du poteau.Also, in order to simplify the use of parking shutters, have motorized devices with electric actuation been proposed, capable of being controlled remotely by emission of infrared radiation, in the manner of gates, barriers or similar. The proposed constructions use a geared motor which is housed in the frame or base sealed in the ground and which is arranged to ensure the pivoting of the post.

Un tel agencement ne peut donner satisfaction en pratique. En effet, l'implantation du moto-réducteur électrique dans le bâti nécessite de faire comporter à celui-ci une hauteur relativement importante qui implique une excavation profonde. Par ailleurs et surtout, la présence permanente du moto-réducteur dans une excavation du sol accroît de manière considérable les risques d'endommagement du système électrique comme du système mécanique par les écoulements d'eau de pluie et par les dépôts de poussières ou gravillons abrasifs.Such an arrangement cannot give satisfaction in practice. Indeed, the implantation of the electric geared motor in the frame requires to make it comprise a relatively large height which involves a deep excavation. Furthermore and above all, the permanent presence of the gear motor in an excavation of the ground considerably increases the risk of damage to the electrical system as well as to the mechanical system by rainwater flows and by abrasive dust or gravel deposits.

C'est à ces inconvénients qu'entend principalement remédier la présente invention, laquelle consiste dans son essence à loger le moto-réducteur et son système d'alimentation électrique à l'intérieur du profilé qui constitue le poteau escamotable, et à relier l'arbre de sortie dudit moto-réducteur au socle ou bâti au moyen d'un maneton associé à un bras dont l'extrémité libre est articulée dans ledit socle ou bâti, en un point décalé longitudinalement par rapport au pivot du poteau.It is to these drawbacks that the present invention mainly intends to remedy, which consists in its essence in housing the gear motor and its electrical supply system inside the profile which constitutes the retractable post, and in connecting the output shaft of said gear motor to the base or frame by means of a crank pin associated with an arm whose free end is articulated in said base or frame, at a point offset longitudinally relative to the pivot of the post.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

Fig. 1 est une vue en perspective illustrant l'agencement général d'un obturateur de parking établi conformément à l'invention, le poteau étant représenté à la position verticale d'interdiction.Fig. 1 is a perspective view illustrating the general arrangement of a parking shutter established in accordance with the invention, the post being shown in the vertical prohibition position.

Fig. 2 est une coupe longitudinale, le poteau ayant été supposé amené à la position basse escamotée.Fig. 2 is a longitudinal section, the post having been assumed to be brought to the low retracted position.

L'obturateur représenté comprend un poteau 1 constitué par un profilé tubulaire, à section carrée dans l'exemple de réalisation envisagé. L'une des extrémités de ce poteau 1 est agencée pour s'articuler sur un axe horizontal 2 porté par une chape 3 rendue solidaire d'un bâti ou socle 4, lequel est scellé à l'intérieur d'une excavation ménagée dans le sol, en avant de l'emplacement de parking à protéger.The shutter shown comprises a post 1 constituted by a tubular profile, with a square section in the embodiment envisaged. One end of this post 1 is arranged to be articulated on a horizontal axis 2 carried by a yoke 3 made integral with a frame or base 4, which is sealed inside an excavation made in the ground , in front of the parking space to be protected.

A l'opposé de l'axe ou pivot 2, le poteau 1 renferme un moto-réducteur électrique 5 dont l'arbre de sortie 6 est orienté transversalement à l'axe du profilé, en faisant saillie sur l'une des deux faces de celui-ci qui sont orientées perpendiculairement audit pivot 2. Comme montré en fig. 2, sur cet arbre de sortie 6 est engagé le moyeu 7a d'un maneton 7 dont l'extrémité libre est attelée en 8 à un bras 9 à profil contre-coudé. L'extrémité opposée de ce bras 9 s'articule sur un pivot 10 orienté parallèlement au pivot 2 et porté par une chape 11, laquelle est prévue à l'intérieur d'un compartiment latéral 4a du socle ou bâti 4. On observera que le pivot 10 est décalé longitudinalement en avant du pivot 2 du poteau 1.Opposite the axis or pivot 2, the post 1 contains an electric geared motor 5, the output shaft 6 of which is oriented transverse to the axis of the profile, projecting from one of the two faces of the latter which are oriented perpendicular to said pivot 2. As shown in FIG. 2, on this output shaft 6 is engaged the hub 7 has a crank pin 7 whose free end is coupled at 8 to an arm 9 with a bent profile. The opposite end of this arm 9 is articulated on a pivot 10 oriented parallel to the pivot 2 and carried by a yoke 11, which is provided inside a lateral compartment 4 a of the base or frame 4. It will be observed that the pivot 10 is offset longitudinally in front of the pivot 2 of the post 1.

Le calage angulaire du moyeu 7a du maneton 7 sur l'arbre de sortie 6 est opéré à l'aide d'un système de clavette amovible à serrure de condamnation. Ce système comprend un barillet à combinaison 12 associé à une clef amovible de manoeuvre pour la commande angulaire d'un doigt latéral éclipsable 12a, lequel barillet est normalement introduit à l'intérieur d'un manchon 7b solidaire radialement du moyeu 7a ; le doigt 12a est ainsi propre à coopérer par rotation avec une gorge de retenue 7c ménagée à l'intérieur du manchon précité.The angular setting of the hub 7 a of the crank pin 7 on the output shaft 6 is carried out using a removable key system with locking lock. This system comprises a combination barrel 12 associated with a removable operating key for the angular control of an eclipsable lateral finger 12 a , which barrel is normally introduced inside a sleeve 7 b radially integral with the hub 7 a ; the finger 12 a is thus able to cooperate by rotation with a retaining groove 7 c formed inside the aforementioned sleeve.

Le moyeu 7a est maintenu axialement sur l'arbre 6 à l'aide d'une vis terminale 13. On notera en outre que le barillet 12 est pourvu d'une queue longitudinale 12b propre à être introduite dans un trou borgne ménagé radialement dans la périphérie de l'arbre de sortie 6 du moto-réducteur 5.The hub 7 a is axially supported on the shaft 6 by means of a terminal screw 13. It is further noted that the barrel 12 is provided with a longitudinal shank 12b adapted to be inserted into a hole provided radially blind in the periphery of the output shaft 6 of the gear motor 5.

On comprend dans ces conditions que lorsque le barillet 12 est mis en place et retenu à l'intérieur du manchon 7b, la mise en marche du moteur 5 provoque le pivotement angulaire du poteau 1 dans un plan vertical, et ce depuis une position verticale d'interdiction (fig. 1) jusqu'à une position horizontale escamotée (fig. 2) et vice versa. Il convient d'observer que conformément à une disposition avantageuse de l'invention, les axes des organes articulés 6, 8 et 10 sont positionnés pour qu'à la position d'interdiction suivant fig. 1 ils se trouvent en alignement, de façon à assurer l'auto-blocage du système par arc-boutement. Dans ces conditions, un choc appliqué sur le poteau 1 suivant une direction perpendiculaire à celle de l'alignement précité impartit uniquement à l'arbre 6 un effort radial, sans engendrer de couple susceptible d'endommager la transmission mécanique du moto-réducteur 5.It is understood under these conditions that when the barrel 12 is put in place and retained inside the sleeve 7b , the starting of the motor 5 causes the angular pivoting of the post 1 in a vertical plane, and this from a vertical position prohibition (fig. 1) to a horizontal retracted position (fig. 2) and vice versa. It should be observed that in accordance with an advantageous arrangement of the invention, the axes of the articulated members 6, 8 and 10 are positioned so that in the prohibition position according to FIG. 1 they are in alignment, so as to ensure self-locking of the system by bracing. Under these conditions, a shock applied to the post 1 in a direction perpendicular to that of the above-mentioned alignment only imparts to the shaft 6 a radial force, without generating a torque capable of damaging the mechanical transmission of the gear motor 5.

L'alimentation électrique du moto-réducteur 5 peut être opérée soit à l'aide de conducteurs associés au réseau général, soit au moyen d'une batterie ou autre source autonome 14 logée dans ledit poteau, au-dessus du pivot 2. A cette alimentation est associé un système d'interrupteur 15 du type à déclenchement à distance par rayonnements infra-rouges ou similaire. L'utilisateur peut ainsi manoeuvrer à l'abaissement le poteau 1 depuis son véhicule ; de la même manière le redressement de ce poteau ne nécessite aucune manoeuvre manuelle autre que celle de l'émetteur portatif usuel.The power supply of the gear motor 5 can be operated either using conductors associated with the general network, or by means of a battery or other autonomous source 14 housed in said post, above the pivot 2. At this power supply is associated with a switch system 15 of the type triggered remotely by infrared radiation or the like. The user can thus maneuver lowering the post 1 from his vehicle; in the same way the straightening of this pole does not require any manual operation other than that of the usual portable transmitter.

En cas de panne de courant ou autre avarie, il suffit à l'utilisateur de manoeuvrer la serrure du barillet pour retirer celui-ci du manchon 7b. Le moyeu 7a est ainsi libéré de l'arbre 6 du moto-réducteur 5, de sorte que le poteau 1 est susceptible d'être manoeuvré manuellement en dépit du caractère irréversible dudit moto-réducteur.In the event of a power failure or other damage, the user need only operate the barrel lock to remove it from the sleeve 7b . The hub 7 a is thus released from the shaft 6 of the geared motor 5, so that the post 1 is capable of being operated manually despite the irreversible nature of said geared motor.
