Description

La présente invention a pour objet un tourniquet de sécurité, permettant le passage de personnes dans un sens et l'interdisant en sens contraire.The present invention relates to a safety turnstile, allowing the passage of people in one direction and prohibiting it in the opposite direction.

De tels tourniquets sont couramment installés à l'entrée de magasins, de stades ou autres lieux publics pour canaliser les visiteurs.Such turnstiles are commonly installed at the entrance to shops, stadiums or other public places to channel visitors.

Ce tourniquet comprend une tête à laquelle sont fixés des bras s'étendant radialement, et qui est montée rotativement sur un pivot placé sur le sommet d'un poteau de support.This turnstile includes a head to which are attached radially extending arms, and which is rotatably mounted on a pivot placed on the top of a support post.

Pour des raisons de sécurité, en cas de panique, le passage dans le sens de la sortie normalement interdite doit pouvoir être utilisé pour une éventuelle évacuation des lieux. De ce fait, la tête tournante du tourniquet doit pouvoir être enlevée relativement aisément.For security reasons, in the event of panic, the passage in the direction of the normally prohibited exit must be able to be used for a possible evacuation of the premises. Therefore, the rotating head of the turnstile must be able to be removed relatively easily.

Pour satisfaire à cet impératif, le tourniquet est pourvu, dans une réalisation connue, d'une bague pouvant être fixée amoviblement à la base de la tête rotative et autour du sommet du poteau pour maintenir la tête sur le pivot, ce dernier débordant en surplomb au-dessus du sommet du poteau. Cette bague comporte un épaulement fileté, au moyen duquel elle est visée par le bas à la partie inférieure de la tête cylindrique tournante, pour empêcher que cette tête ne puisse s'enlever. Pour dégager la tête, il faut dévisser cette bague qui se désolidarise ainsi dela tête tournante et la libère de son pivot.To meet this requirement, the turnstile is provided, in a known embodiment, with a ring which can be removably fixed at the base of the rotary head and around the top of the post to hold the head on the pivot, the latter overhanging in overhang. above the top of the post. This ring has a threaded shoulder, by means of which it is aimed from below at the lower part of the rotating cylindrical head, to prevent this head from being able to be removed. To disengage the head, it is necessary to unscrew this ring which thus separates from the rotating head and releases it from its pivot.

Cette réalisation présente l'inconvénient provenant du fait que le vissage et le dévissage nécessitent généralement de faire exécuter plusieurs tours complets à la bague. Cette opération prend donc nécessairement un temps plus long qu'il ne serait souhaitable pour dégager la tête tournante s'il se produit un mouvement de panique vers la sortie contrôlée par le tourniquet.This embodiment has the drawback that the screwing and unscrewing generally require the ring to be made several full turns. This operation therefore necessarily takes a longer time than would be desirable to disengage the rotating head if there is a panic movement towards the outlet controlled by the turnstile.

Suivant l'invention, une couronne est fixée ou ménagée à la base de la tête en réservant un passage annulaire entre, d'une part, le sommet du poteau, et d'autre part la couronne et la base de la tête, et dans cette couronne sont ménagées des encoches dans lesquelles peuvent venir s'encliqueter des tétons saillants correspondants de la bague de telle sorte que cette dernière puisse prendre deux positions angulaires dans la couronne: une première position dans laquelle la bague est désolidarisée de la couronne et par conséquent de la tête qui peut être enlevée du poteau, et une seconde position dans laquelle la bague est solidaire de la couronne et retient la tête sur le pivot et le poteau, ces deux positions étant séparées d'un intervalle angulaire prédéterminé.According to the invention, a crown is fixed or formed at the base of the head by reserving an annular passage between, on the one hand, the top of the post, and on the other hand the crown and the base of the head, and in this crown are provided with notches in which the corresponding projecting studs of the ring can snap in so that the latter can take two angular positions in the crown: a first position in which the ring is detached from the crown and consequently of the head which can be removed from the post, and a second position in which the ring is integral with the crown and retains the head on the pivot and the post, these two positions being separated by a predetermined angular interval.

Cet intervalle peut être par exemple de 45 degrés, de telle sorte que pour passer de la position d'enclenchement de la bague sur la couronne à sa position de libération permettant le dégagement de la tête tournante du tourniquet, il suffit d'une rotation de 45 degrés. Cette opération de libération de la tête par rapport au pivot peut donc être effectuée beaucoup plus rapidement qu'avec la réalisation antérieure à bague filetée.This interval can be for example 45 degrees, so that to pass from the position of engagement of the ring on the crown to its release position allowing the release of the rotating head of the turnstile, it suffices to rotate 45 degrees. This operation of releasing the head relative to the pivot can therefore be carried out much more quickly than with the previous embodiment with a threaded ring.

Dans un mode de réalisation de l'invention, la bague comporte une collerette intérieure saillante coaxiale au poteau, apte à être introduite dans le passage annulaire entre la tête et le poteau, et pourvue d'au moins deux tétons adaptés pour s'engager dans deux encoches associées formées dans la couronne, et au moins deux crans sont agencés dans ladite collerette à des intervalles angulaires prédéterminés des encoches correspondantes, par exemple 45 degrés, afin de recevoir les tétons de la bague après une rotation correspondante de cette dernière, des moyens d'encliquetage élastique étant prévus pour bloquer les tétons dans les cranset par suite pour solidariser la bague avec la couronne et la tête.In one embodiment of the invention, the ring has a projecting inner flange coaxial with the post, capable of being introduced into the annular passage between the head and the post, and provided with at least two pins adapted to engage in two associated notches formed in the crown, and at least two notches are arranged in said flange at predetermined angular intervals of the corresponding notches, for example 45 degrees, in order to receive the pins of the ring after a corresponding rotation of the latter, means elastic snap being provided to block the pins in the cranset as a result to secure the ring with the crown and the head.

Ces moyens d'encliquetage maintiennent donc normalement la tête fixée au pivot et au poteau, mais ils sont agencés de manière à pouvoir s'effacer sous l'effet d'une force antagoniste exercée sur la bague, ce qui permet alors de faire exécuter à ces éléments une rotation relative de 45 degrés jusqu' à la position de libération de la tête.These latching means therefore normally keep the head fixed to the pivot and to the post, but they are arranged so as to be able to disappear under the effect of an opposing force exerted on the ring, which then makes it possible to cause the these elements a relative rotation of 45 degrees to the release position of the head.

On a représenté à la figure 1 un tourniquet de sécurité susceptible d'être installé à l'entrée d'un magasin, d'un stade ou autres lieux pour canaliser les visiteurs.There is shown in Figure 1 a security turnstile may be installed at the entrance of a store, stadium or other places to channel visitors.

Ce tourniquet comprend une tête 1, de forme cyclindrique, à laquelle sont fixés des bras 2 s'étendant radialement, au nombre de quatre disposés à angle droit, et qui est monté rotativement sur un poteau 3 vertical de support, par l'intermédiaire d'un pivot non visible sur la figure 1.This turnstile comprises a head 1, of cylindrical shape, to which are fixed arms 2 extending radially, four in number arranged at right angles, and which is rotatably mounted on a vertical support post 3, by through a pivot not visible in Figure 1.

De façon connue en soi, la tête rotative 1 est agencée de manière à autoriser s'entrée des clients ou des visiteurs dans un sens de rotation, et à interdire la sortie dans le sens opposé, la rotation de la tête 1 et des bras 2 étant automatiquement empêchée dans le sens de la sortie.In a manner known per se, the rotary head 1 is arranged so as to allow the entry of customers or visitors in a direction of rotation, and to prohibit the exit in the opposite direction, the rotation of the head 1 and of the arms 2 being automatically prevented in the direction of exit.

Les bras 2 sont fixés à la tête 1 de la façon illustrée à la figure 2, connue en soi. La tête cylindrique 1 présente un logement intérieur 4, de forme générale cyclindrique, et à l'intérieur duquel vient prendre place un pivot cylindrique 5 correspondant, qui prend appui sur le sommet du poteau vertical 3 auquel il est fixé par une série de vis 6. Celles-ci traversent donc le pivot 5 et viennent se visser à l'intérieur d'une douille 7 encastrée à l'intérieur du sommet du poteau 3 et solidaire de celui-ci.The arms 2 are fixed to the head 1 in the manner illustrated in FIG. 2, known per se. The cylindrical head 1 has an internal housing 4, of generally cyclindrical shape, and inside which a corresponding cylindrical pivot 5 takes place, which rests on the top of the vertical post 3 to which it is fixed by a series of screws 6 These therefore pass through the pivot 5 and are screwed inside a socket 7 embedded inside the top of the post 3 and integral with the latter.

A sa partie supérieure, le logement 4 présente un épaulement annulaire 8 contre lequel le pivot 5 vient en butée. D'autre part, le pivot 5 a un diamètre supérieur à celui du poteau 3, au-dessus duquel il déborde donc en surplomb comme on le voit clairement à la figure 2. La partie inférieure de la tête 1 s'étend au-dessous de la base du pivot 5, et délimite donc avec ce dernier et le sommet du poteau 3 un volume ou passage annulaire 9.At its upper part, the housing 4 has an annular shoulder 8 against which the pivot 5 abuts. On the other hand, the pivot 5 has a diameter greater than that of the post 3, above which it therefore overhangs, as can be clearly seen in FIG. 2. The lower part of the head 1 extends below of the base of the pivot 5, and therefore delimits with the latter and the top of the post 3 an annular volume or passage 9.

Une couronne 11 est fixée à la base annulaire de la tête 1 en laissant libre le passage annulaire 9, la fixation à la tête 1 pouvant être réalisée par tous moyens appropriés tels que des vis 12. La couronne 11 comporte une collerette intérieure saillante 13 coaxiale au poteau 3, apte à être introduite dans le passage annulaire 9 et plus précisément agencée pour s'encastrer dans un logement annulaire 9a formé sur le pourtour intérieur de la base de la tête 1 (figure 2). La collerette 13 est pourvue de deux encoches 14 diamétralement opposées, s'étendant sur toute la hauteur de ladite collerette, ainsi que de deux crans 15 également diamétralement opposés, distants angulairement chacun de 45° de l'encoche 14 contiguë, et s'étendant sur seulement une partie de la hauteur de la collerette 13. Les crans 15 sont séparés des encoches 14 par deux redans ou ressauts saillants 16.A ring 11 is fixed to the annular base of the head 1, leaving the annular passage 9 free, the fixing to the head 1 can be achieved by any appropriate means such as screws 12. The ring 11 has a projecting inner collar 13 coaxial to the post 3, adapted to be introduced into the annular passage 9 and more precisely arranged to fit into an annular housing 9a formed on the inner periphery of the base of the head 1 (FIG. 2). The flange 13 is provided with two diametrically opposite notches 14, extending over the entire height of said flange, as well as two notches 15 also diametrically opposed, angularly spaced each 45 ° from the contiguous notch 14, and extending over only part of the height of the collar 13. The notches 15 are separated from the notches 14 by two protruding steps or projections 16.

Le tourniquet comprend également une bague 17 présentant un diamètre intérieur sensiblement égal à celui du poteau 3 afin de pouvoir être emboîté sur celui-ci. La bague 17 comporte un collet intérieur saillant 18, coaxial au poteau 3, et dont le diamètre est sensiblement inférieur à celui de la collerette 13 afin de pouvoir venir s'introduire dans l'espace annulaire 9 réservé entre la collerette 13 et le sommet du poteau 3. Le collet 18 est pourvu de deux tétons 19 diamétralement opposés, qui s'étendent radialement vers l'extérieur et sont adaptés pour pouvoir s'engager dans les deux encoches correspondantes 14 lorsqu'on fait coulisser le collet 18 dans la bague 11, les tétons 19 étant placés en correspondance avec les encoches 14. Dans cette position relative de la bague 17 et de la couronne 11, ces deux pièces ne sont pas solidarisées ensemble, et par conséquent la tête 1 peut être enlevée sans obstacle du sommet du poteau 3.The turnstile also comprises a ring 17 having an internal diameter substantially equal to that of the post 3 so that it can be fitted thereon. The ring 17 has a protruding inner collar 18, coaxial with the post 3, and whose diameter is substantially less than that of the collar 13 so as to be able to be introduced into the annular space 9 reserved between the collar 13 and the top of the post 3. The collar 18 is provided with two diametrically opposed nipples 19 which extend radially outwards and are adapted to be able to engage in the two corresponding notches 14 when the collar 18 is slid in the ring 11 , the pins 19 being placed in correspondence with the notches 14. In this relative position of the ring 17 and the crown 11, these two parts are not secured together, and therefore the head 1 can be removed without obstacle from the top of the post 3.

Si maintenant, à partir de cette position, on fait tourner la bague 17 de façon que les tétons 19 glissent sur les redans 16, les tétons 19 viennent s'encastrer dans les crans 15 après une rotation de 45 degrés par rapport à la couronne 1. Du fait que les crans 15 ne s'étendent que sur une partie de la hauteur de la couronne 11, celle-ci est solidarisée dans cette position des tétons 19 avec la bague 17, qui fixe par conséquent la tête 1 sur le poteau 3.If now, from this position, the ring 17 is rotated so that the pins 19 slide on the notches 16, the pins 19 come to be embedded in the notches 15 after a rotation of 45 degrees relative to the crown 1 Because the notches 15 only extend over part of the height of the crown 11, the latter is secured in this position of the studs 19 with the ring 17, which consequently fixes the head 1 on the post 3 .

L'invention prévoit également des moyens d'encliquetage élastique pour bloquer la bague 17 sur la couronne 11 lorsque les tétons 19 sont encastrés dans les crans 15. Dans l'exemple de réalisation décrit, ces moyens sont constitués par deux organes élastiques 21 formés de deux languettes diamétralement opposées sur le corps 17a de la bague 17, et plus précisément dans la plage annulaire 17b entourant le collet 18 (figures 3 et 6). Ces languettes 21 peuvent être réalisées d'une seule pièce avec le reste de la bague 17 au moment du moulage de celle-ci, par exemple en une matière plastique appropriée, et elles font normalement légèrement saillie par rapport à la surface de la plage annulaire 17b, tout en pouvant s'abaisser en s'introduisant dans des logements correspondants 22 lorsqu'elles subissent une poussée vers le bas. Dans ces conditions, lorsqu'on emboîte les tétons 19 dans les encoches 14, la couronne 11 repose sur les languettes élastiques 21, qui peuvent s'effacer dans les logements 22 en appliquant avec une force suffisante la couronne 1 et la bague 17 l'une contre l'autre. Une fois cet effacement réalisé, on peut faire pivoter la bague 17 sur les redans 16 jusqu'à encliquetage des tétons 19 dans les crans 15. Dans cette position, lorsqu'on relâche la pression sur la bague 17, les languettes 21 se redressent et appliquent une force élastique sur la couronne 11, qui tend maintenir celle-ci solidarisée avec la bague 17.The invention also provides elastic latching means for locking the ring 17 on the crown 11 when the pins 19 are embedded in the notches 15. In the embodiment described, these means consist of two elastic members 21 formed of two diametrically opposite tongues on the body 17a of the ring 17, and more precisely in the annular region 17b surrounding the collar 18 (Figures 3 and 6). These tongues 21 can be made in one piece with the rest of the ring 17 at the time of molding thereof, for example in a suitable plastic, and they normally project slightly from the surface of the annular area 17b, while being able to be lowered by introducing into corresponding housings 22 when they are subjected to a downward thrust. Under these conditions, when the nipples 19 are fitted into the notches 14, the crown 11 rests on the elastic tongues 21, which can disappear in the housings 22 by applying the crown 1 and the ring 17 with sufficient force. one against the other. Once this erasing has been carried out, the ring 17 can be pivoted on the steps 16 until the studs 19 click into the notches 15. In this position, when the pressure on the ring 17 is released, the tongues 21 straighten out and apply an elastic force to the crown 11, which tends to keep the latter secured to the ring 17.

La mise en oeuvre du tourniquet de sécurité qui vient d'être décrit se comprend aisément et est la suivante.The implementation of the security turnstile which has just been described is easily understood and is as follows.

On engage la bague 17 sur le poteau 3, puis on fixe sur celui-ci le pivot central 5 au moyen des vis 6. On met ensuite en place la tête tournante 1, munie de la couronne 11, sur le pivot central 5. On engage les tétons 19 de la bague 17 dans les encoches 14. Dès que ces tétons arrivent en butée contre l'épauelement annulaire 9a, on fait pivoter la bague 17 de manière à faire glisser les tétons 19 sur les redans 16, et à venir les encastrer dans les crans 15, après rotation de 45 degrés. L'engagement des tétons 19 dans les encoches 14 est illustré à la figure 4, tandis que leur encliquetage dans les crans 15 est représenté à la figure 5. Dans cette seconde position, on lâche la bague 17, et les languettes 21, qui jusque là avaient été escamotées dans leurs logements 22, se redressent élastiquement en exerçant sur la couronne 11 une force dirigée vers le haut, qui maintient la bague 17 bloquée sur la couronne 11 par appui contre la face inférieure de cette dernière. La bague 17 est donc ainsi rendue solidaire de la tête tournante 1, qui ne peut plus être enlevée du poteau 3 sans une manoeuvre particulière de déblocage.The ring 17 is engaged on the post 3, then the central pivot 5 is fixed thereon by means of the screws 6. The rotary head 1, fitted with the crown 11, is then placed on the central pivot 5. engages the pins 19 of the ring 17 in the notches 14. As soon as these pins arrive in abutment against the annular spalling 9a, the ring 17 is pivoted so as to slide the pins 19 on the steps 16, and to come the embed in notches 15, after rotation of 45 degrees. The engagement of the pins 19 in the notches 14 is illustrated in FIG. 4, while their engagement in the notches 15 is shown in FIG. 5. In this second position, the ring 17 and the tongues 21 are released, which up to there had been retracted into their housings 22, straighten elastically by exerting on the crown 11 an upwardly directed force, which keeps the ring 17 locked on the crown 11 by pressing against the underside of the latter. The ring 17 is thus made integral with the rotating head 1, which can no longer be removed from the post 3 without a particular release operation.

Pour exécuter ce déblocage, il suffit d'appliquer une poussée verticale vers le haut sur la bague 17.To execute this release, it suffices to apply a vertical upward thrust on the ring 17.

Cette poussée dégage les tétons 19 des crans 15, après quoi on fait tourner la bague 17 de 45 degrés jusqu'à ce que les tétons 19 viennent dans les encoches 14. A ce moment, la bague 17 est libérée de la couronne 11 et de ce fait la tête 1 peut être enlevée du poteau 3. Ce mouvement de rotation est signalé sur la face extérieure de la bague 17 par des flèches 23 (figure 6).This thrust releases the pins 19 from the notches 15, after which the ring 17 is rotated 45 degrees until the pins 19 come into the notches 14. At this time, the ring 17 is released from the crown 11 and this fact the head 1 can be removed from the post 3. This rotational movement is indicated on the outer face of the ring 17 by arrows 23 (Figure 6).

Dans ces conditions, la tête 1 peut être très aisément et rapidement séparée du poteau 3 par une simple poussée verticale suivie d'une rotation de 45 degrés, ce qui constitue un avantage appréciable en cas de panique dans le magasin ou le bâtiment dont l'entrée est contrôlée par le tourniquet selon l'invention, afin de faciliter la sortie.Under these conditions, the head 1 can be very easily and quickly separated from the post 3 by a simple vertical push followed by a rotation of 45 degrees, which constitutes an appreciable advantage in the event of panic in the store or the building whose entry is controlled by the turnstile according to the invention, in order to facilitate exit.

On pourrait prévoir un nombre de tétons 19, d'encoches 14 et de crans 15 supérieur à deux, par exemple trois, séparés par des intPrvalles angulaires de 120°. De même, on peut am&r'ager plus de deux languettes élastiques 19, ou les remplacer par tous autres organes d'encliquetage élastique équivalents.One could provide a number of pins 19, notches 14 and notches 15 greater than two, for example three, separated by int P rvalles angular of 120 °. Similarly, we can & r am ager more than two elastic tongues 19, or replaced by any other equivalent resilient snap organs.

Claims (4)

1. Safety turnstile to be installed at the entrance of a store, of a stadium, or of any other location for guiding the influx of visitors, comprising a head (1) to which arms (2) are attached and which is rotatably mounted on a pivot (5) placed on the top end of a supporting post (3), as well as a ring (17) which can be removably attached to the base of the rotary head (1) and around the top end of the post (3) in order to maintain the head (1) on the pivot (5), this latter being disposed in a projecting and overhung position above the top of the post (3), characterized in that an annular member (11) is fixed or arranged beneath the base of the head (1) so as to provide an annular passage (9) between on the one hand the top of the post (3) and on the other hand the annular member (11) and the base of the head (1), provision being made in this annular member (11) for slots (14) in which corresponding projecting lugs (19) of the ring (17) are capable of resilient snap-action engagement, with the result that this latter is capable of taking up two angular positions within the annular member (11); a first position in which the ring (17) is disengaged from the annular member (11) and consequently from the head (1) which can be detached from the post (3), and a second position in which the ring (17) is rigidly fixed to the annular member (11) and retains the head (1) on the pivot (5) and the post (3), these two positions being separated by a predetermined angular interval.
2. Turnstile in accordance with claim 1, characterized in that the ring (17) is provided with a projecting internal annular collar (18) which is coaxial with the post (3), which can be introduced within the annular passage (9) between the head (1) and the post (3), and which is provided with at least two lugs (19) adapted to engage within two associated slots (14) formed in the annular member (11), and at least two recesses (15) are formed in said annular collar (11) at predetermined angular intervals such as 45 degres, for example, with respect to the corresponding slots (14) in order to receive the lugs (19) of the ring (17) after a corresponding rotation of this latter, resilient snap-action engagement means being provided for locking the lugs (19) within the recesses (15) and consequently for coupling the ring (17) with the annular member (11) and the head (1) in interlocked relation.
3. Turnstile in accordance with claim 2, characterized in that the slots (14) extend to the full height of an annular collar (13) whose diameter exceeds that of the annular collar (18) of the ring (17) in order to permit free introduction of the lugs (19) within these latter whilst the recesses (15) for retaining the lugs (19) are formed only in the upper portion of the annular collar (13) and are separated from the slots (14) by intercalary stepped projections (16), and resilient members are arranged on the ring (17) around the annular collar (18) in order to exert a resilient thrust on the ring (11) with the result that a pressure must first be exerted by the ring (17) on the annular member (11) in order to move the lugs (19) from the slots (14) into the recesses (15) and in order to overcome the oppositely-acting thrust of these resilient members, whereupon the ring (17) can be displaced in pivotal motion with respect to the annular member (11) by causing the lugs (19) to slide over the stepped projections (16), the lugs (19) being then engaged by resilient snap-action within the recesses (15) in which they are resiliently maintained by means of the retaining members, the ring (17) being then locked in the annular member (11) and the head (1) of the turnstile being consequently maintained in the second position aforesaid.
4. Turnstile in accordance with claim 3, characterized in that the retaining members are constituted by at least two resilient tongues (21) secured to the ring (17) and capable of engaging within recesses (22) of this latter under the thrust exerted by the ring (17) on the annular member (11).
