Abstract
Description
L'objet de l'invention concerne un dispositif de barrière automatique à chaines. The object of the invention relates to an automatic chain barrier device.
I1 est destiné aux accès des résidences, aux entrées de parking et autres interdictions de passages. It is intended for access to residences, parking entrances and other passage restrictions.
Dans les dispositifs connus, on fixait généralement une extrémité de la chaîne à la partie haute d'un potelet, alors que lrautre extrémité était tractée par un pignon entraîné par un moto-réducteur. In known devices, one end of the chain was generally fixed to the upper part of a post, while the other end was pulled by a pinion driven by a gear motor.
Ce montage présentait de nombreux inconvénients, d'abord en position baissée, la chaine fixée à ses deux extrémités formait deux courbes non escamotées dans 1 'affouillement récepteur qui risquaient toujours un arrachement par le véhicule. This assembly had many drawbacks, first in the lowered position, the chain fixed at its two ends formed two non-retracted curves in one receiver scour which always risked being torn off by the vehicle.
Ensuite la chaine tractée par une extrémité fixée sur le potelet provoquait une tension soumettant le potelet à des efforts provoquant souvent sa torsion ou son descellement. Then the chain pulled by one end fixed on the post caused a tension subjecting the post to efforts often causing its twisting or loosening.
Le dispositif suivant l'invention supprime ces inconvénients, évite la tension de la chaîne en permettant son simple soulèvement, ce qui réduit 1 ' effort fourni par le moto-réducteur et ne provoque aucune tension tout en assurant l'escamotage total de la chaîne en position basse où elle conserve un parfait parallélisme avec l'affouillement récepteur. The device according to the invention eliminates these drawbacks, avoids chain tension by allowing its simple lifting, which reduces one effort provided by the gear motor and does not cause any tension while ensuring the total retraction of the chain in low position where it retains perfect parallelism with the receiver scour.
Il est constitué par deux potelets parallèles avec obliquité identique de même sens formant rampe de coulissement, l'une tubulaire guidant un coulisseau relié à une extrémité de la chaîne tractée par un moto-réducteur, l'autre profilée guidant une poulie à gorge montée libre et retenant 1 ' extrémité opposée de la chaîne par un étrier. It consists of two parallel posts with identical obliquity in the same direction forming a sliding ramp, one tubular guiding a slider connected to one end of the chain towed by a gear motor, the other profiled guiding a pulley with free-mounted groove and retaining the opposite end of the chain by a yoke.
Sur les dessins annéxés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention:
La figure 1 représente vu en élévation 1 'ensemble du dispositif.In the appended drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention:
Figure 1 shows an elevational view of the entire device.
la figure 2 montre vue en coupe longitudinale la poulie guide. Figure 2 shows a view in longitudinal section of the guide pulley.
La chaîne 1 a la dimension du passage à protéger. Chain 1 has the dimension of the passage to be protected.
Elle est positionnée entre deux montants 2, 3 qui délimitent la largeur de l'accès. It is positioned between two uprights 2, 3 which delimit the width of the access.
Le pilier 2 supporte le moto-réducteur protégé par le carter 4. The pillar 2 supports the geared motor protected by the casing 4.
Chaque extrémité 5, 6 de la chaîne est reliée à un potelet oblique 7, 8. Each end 5, 6 of the chain is connected to an oblique post 7, 8.
Ces deux potelets sont parallèles et ont une obliquité d'environ 30 à 35 , de façon à former deux rampes. These two posts are parallel and have an obliquity of about 30 to 35, so as to form two ramps.
Le potelet 7, figures 1, 2 est tubulaire, de section carrée et comporte sur sa face 9, une coulisse 10 ouverte sur toute sa hauteur. The post 7, Figures 1, 2 is tubular, of square section and has on its face 9, a slide 10 open over its entire height.
Dans ce profilé se déplace un coulisseau 11 de section parallèlèpipédique, avec anneau 12, relié au câble 13 entraîné par le moto-réducteur qui assure son relèvement. Une attache 14 retient l'extrémité 5 de la chaine 1. In this section moves a slide 11 of parallelepipedic section, with ring 12, connected to the cable 13 driven by the gear motor which ensures its recovery. A fastener 14 retains the end 5 of the chain 1.
Le potelet 8 est de section carrée et sert de guide à la poulie à gorge 15 dont l'étrier 16 avec l'anneau 17 reçoit l'extrémité 6 de la chaîne 1. The post 8 is of square section and serves as a guide for the grooved pulley 15 whose stirrup 16 with the ring 17 receives the end 6 of the chain 1.
Lorsque le coulisseau 11 est tracté, flèche A vers la partie haute, la poulie 15 suit exactement le même déplacement il glisse sans effort, ni à-coups sur le rail 8. When the slider 11 is pulled, arrow A towards the top, the pulley 15 follows exactly the same movement; it slides effortlessly or jerkily on the rail 8.
Par contre, lorsque le câble relâche le coulisseau 11, flèche B, le propre poids de ce dernier, auquel s'ajoute celui de la chaîne 1, entrain la poulie 15, qui suit le même parcours, avec la même amplitude de translation. By cons, when the cable releases the slider 11, arrow B, its own weight, to which is added that of the chain 1, causes the pulley 15, which follows the same path, with the same amplitude of translation.
La chaîne s'escamote dans l'affouillement 18, dans une position parallèle sans dépacement ni saillie. The chain retracts into the scour 18, in a parallel position without separation or projection.
La commande du moto-réducteur 4 peut être téléguidée. The control of the gear motor 4 can be remote-controlled.
La puissance motrice est réduite dans de très grandes proportions et le fonctionnement est d'une régularité parfaite, sans à-coups ni même possibilité de grippage. The engine power is reduced in very large proportions and the operation is of perfect regularity, without jerks or even possibility of seizing.
Tous les organes sont facilement accessibles, et en tout état de cause, en cas de pane de courant maniable à la main, aussi bien pour libérer l'accès en cas de panne de courant, que pour remonter le coulisseau 11. All the organs are easily accessible, and in any event, in the event of a power failure which is handy by hand, both for freeing access in the event of a power failure and for reassembling the slide 11.
Cependant, les formes, dimensions et dispositions des différents éléments, comme d ' ailleurs les matières utilisées pour leur fabrication, pourront varier dans la limite des équivalents, sans changer pour cela la conception générale de 1 'invention qui vient d ' être décrite. However, the shapes, dimensions and arrangements of the various elements, like the materials used for their manufacture, may vary within the limit of the equivalents, without thereby changing the general conception of the invention which has just been described.
