Description
La présente invention est relative aux tourniquets utilisés pour assurer le contrôle de l'accès à un lieu déterminé, tel que magasin, salle d'exposition, salle de spectacle, etc...The present invention relates to turnstiles used to control access to a specific place, such as a store, exhibition hall, performance hall, etc.
Plus précisément l'invention concerne les tourniquets de ce genre qui sont constitués par une série de bras horizontaux rayonnant autour d'un moyeu monté rotatif autour d'un noyau fixe porté par un poteau, et qui comporte des organes mobiles de blocage n'autorisant la rotation de ce moyeu que dans un seul sens. Ces organes, consistent en général en des rouleaux verticaux disposés à l'intérieur d'encoches prévues sur la périphérie du noyau, et qui sont soumis à l'action de moyens élastiques de poussée agissant sur chacun d'eux.More specifically, the invention relates to turnstiles of this kind which are constituted by a series of horizontal arms radiating around a hub rotatably mounted around a fixed core carried by a post, and which comprises movable blocking members not allowing the rotation of this hub only in one direction. These members generally consist of vertical rollers arranged inside notches provided on the periphery of the core, and which are subjected to the action of elastic pushing means acting on each of them.
Cependant, les tourniquets actuels, de ce genre comportent des mécanismes relativement compliqués et coûteux. Par ailleurs, leur fonctionnement est peu fiable.However, current turnstiles of this kind have relatively complicated and expensive mechanisms. Furthermore, their operation is unreliable.
Ainsi, le brevet US 3 559 341 décrit un tourniquet du type en cause dans lequel il est prévu un noyau central comportant, à sa périphérie, plusieurs encoches servant chacune de logement à un rouleau de blocage et à des moyens élastiques agissant sur ce rouleau. Mais la structure du mécanisme de ce tourniquet est relativement compliquée et coûteuse.Thus, US Pat. No. 3,559,341 describes a turnstile of the type in question in which there is provided a central core comprising, at its periphery, several notches each serving as a housing for a locking roller and for elastic means acting on this roller. However, the structure of the mechanism of this turnstile is relatively complicated and expensive.
C'est pourquoi, la présente invention a pour objet un tourniquet du même genre qui est conçu de façon à présenter une structure très simple et à comporter un fonctionnement très fiable.This is why, the present invention relates to a turnstile of the same kind which is designed so as to have a very simple structure and to include a very reliable operation.
Ce tourniquet qui est constitué par une série de bras horizontaux rayonnant autour d'un moyeu creux monte rotatif autour d'un noyau fixe porté par un poteau et pourvu de rouleaux de blocage n'autorisant la rotation de ce moyeu que dans un seul sens, ces rouleaux étant disposés dans des encoches de la périphérie de ce noyau de même que chacun des organes élastiques agissant sur un tel rouleau, est caractérisé en ce que les rouleaux de blocage comportent des tourillons à leurs extrémités, et les organes élastiques agissant sur ces rouleaux de blocage consistent en des bâtonnets en matière plastique, et en ce que les tourillons des rouleaux de blocage ainsi que les extrémités des bâtonnets élastiques sont montés coulissants dans des rainures de guidage prévues sur les faces en regard des deux disques de retenue rapportés de part et d'autre du noyau fixe.This turnstile which is constituted by a series of horizontal arms radiating around a hollow hub rotates around a fixed core carried by a post and provided with locking rollers allowing the rotation of this hub only in one direction, these rollers being arranged in notches on the periphery of this core as well as each of the elastic members acting on such a roller, is characterized in that the blocking rollers have pins at their ends, and the elastic members acting on these rollers of locking consist of plastic sticks, and in that the trunnions of the blocking rollers as well as the ends of the elastic sticks are slidably mounted in guide grooves provided on the opposite faces of the two retaining discs attached in part and on the other of the fixed core.
Ainsi les rouleaux de blocage se trouvent retenus sur le corps du noyau du fait de l'engagement de leurs tourillons d'extrémité à l'intérieur des rainures prévues sur les faces en regard des deux disques disposés de part et d'autre du corps de ce noyau. En conséquence les éléments constitutifs de ce mécanisme forment un ensemble pouvant être aisément manipulé lors des opérations de montage et de démontage et ce, sans aucun risque de détérioration.Thus the locking rollers are retained on the body of the core due to the engagement of their end journals inside the grooves provided on the opposite faces of the two discs arranged on either side of the body of this core. Consequently, the constituent elements of this mechanism form an assembly which can be easily manipulated during assembly and disassembly operations, without any risk of deterioration.

- La figure 1 est une vue en élévation avec arrachement, d'un tourniquet selon l'invention ;
- La figure 2 est une vue en perspective des différents éléments constitutifs du noyau fixe de ce tourniquet ;
- Les figures 3 et 4 sont des vues en coupe selon la ligne III-III de la figure 1, respectivement lors du blocage du tourniquet et lors de la rotation libre de celui-ci.
- Figure 1 is an elevational view with cutaway, of a turnstile according to the invention;
- Figure 2 is a perspective view of the various components of the fixed core of this turnstile;
- Figures 3 and 4 are sectional views along line III-III of Figure 1, respectively during the locking of the turnstile and during the free rotation thereof.
Le présent tourniquet comporte une série de bras horizontaux 1 rayonnant autour d'un moyeu creux 2 dont ils sont solidaires. Ce moyeu comporte une cavité 3 débouchant à sa partie inférieure. A l'intérieur de celle-ci est disposé un noyau cylindrique, désigné par la référence générale 4, et qui est destiné à constituer le pivot de rotation du moyeu 2, ce noyau étant porté par un poteau 5 susceptible d'être fixé au sol.The present turnstile comprises a series of
Conformément à l'invention, le noyau fixe de ce tourniquet est constitué par un corps cylindrique 6 disposé entre deux disques supérieur 7 et inférieur 8. Ces trois pièces sont solidarisées entre elles par exemple par deux goupilles élastiques fendues 9, engagées dans des alésages complémentaires 10 prévus à la fois dans le corps cylindrique 6 et dans les deux disques 7 et 8.According to the invention, the fixed core of this turnstile is constituted by a cylindrical body 6 disposed between two upper 7 and lower 8 discs. These three parts are joined together for example by two split
A sa périphérie, le corps cylindrique 6 présente trois encoches 11 servant de logement à trois rouleaux de blocage 12. La largeur de ces encoches est telle que chacun de ces rouleaux puisse être déplacé entre une position d'escamotage dans la partie centrale de chaque encoche (voir figure 4) et une position de saillie partielle dans laquelle ces rouleaux se trouvent placés près de l'extrémité de plus faible profondeur de ces encoches (voir figure 3).At its periphery, the cylindrical body 6 has three
Chacun de ces rouleaux porte, à l'une et l'autre de ses extrémités, un tourillon 13 qui est engagé dans une rainure de retenue 14 pratiquée dans la face en regard de l'un ou l'autre disque 7 ou 8. L'axe de ces rainures est disposé dans une orientation angulaire identique à celle du fond des encoches 11 de façon à guider convenablement les rouleaux de blocage 12 dans leurs déplacements.Each of these rollers carries, at both of its ends, a
Les moyens élastiques de rappel agissant sur les rouleaux de blocage consistent en des bâtonnets élastiques ou des petits tubes élastiques 15 dont les extrémités sont également engagées dans les rainures de retenue 14. Ces bâtonnets ou tubes élastiques sont disposés dans l'extrémité la plus profonde des encoches 11 afin de repousser les rouleaux de blocage vers l'extrémité opposée.The elastic return means acting on the locking rollers consist of elastic rods or small
Le noyau ainsi constitué est fixé sur l'extrémité supérieure du poteau 5 au moyen de trois vis 16 engagées à travers des alésages complémentaires 17 pratiqués dans les différents éléments constitutifs de ce noyau. Les extrémités de ces vis sont alors vissées dans des trous taraudés 18 prévus sur la tête supérieure 19 du poteau 5.The core thus formed is fixed to the upper end of the
Les rouleaux de blocage se trouvent maintenus sur le corps cylindrique 6 du présent noyau du fait de l'engagement de leurs tourillons d'extrémité 13 à l'intérieur des rainures 14 des deux disques 7 et 8 rapportés de part et d'autre de ce corps. Néanmoins ces rouleaux sont en mesure d'effectuer les déplacements nécessaires entre leur position de blocage représentée à la figure 3, et leur position d'escamotage permettant la libre rotation du tourniquet, laquelle position est représentée à la figure 4. Le noyau fixe ainsi constitué peut être aisément monté et démonté sans risque de détérioration, car ses différents éléments constitutifs sont parfaitement assemblés les uns avec les autres et forment un ensemble homogène.The locking rollers are held on the cylindrical body 6 of the present core due to the engagement of their
Le présent tourniquet n'est pas limité à l'exemple de réalisation indiqué ci-dessus. Les moyens de rappel élastiques des rouleaux de blocage pourraient être réalisés différemment. Par ailleurs la solidarisation du corps cylindrique 6 avec les deux disques 7 et 8 pourrait être réalisée de façon différente.The present turnstile is not limited to the exemplary embodiment indicated above. The elastic return means of the locking rollers could be produced differently. Furthermore, the attachment of the cylindrical body 6 with the two
