Description

La présente invention est relative à une machine pour le tirage aléatoire de boules, du genre de celles utilisées, par exemple, pour le tirage des loteries.The present invention relates to a machine for the random drawing of balls, of the kind used for example, for drawing lotteries.

Ces machines comportent de petites boules, repérées par un numéro,placées dans un réceptacle comportant des moyens pour les agiter et les extraire une à une, de façon aléatoire.These machines include small balls, identified by a number, placed in a receptacle comprising means for agitating and extracting them one by one, randomly.

Ces machines doivent remplir trois critères.These machines must meet three criteria.

En premier lieu, elles doivent être fiables et le tirage doit être parfaitement aléatoire.First, they must be reliable and the draw must be perfectly random.

En second lieu, comme les tirages sont publics, elles doivent présenter un intérêt visuel.Second, since the prints are public, they must be of visual interest.

Enfin,pour des raisons liées à la psychologie des partici­pants à la loterie,il est essentiel que chaque joueur qui assiste au tirage n'ait aucun doute sur l'origine de la boule extraite. En d'autres termes, dès qu'une boule est saisie, de façon aléatoire, par le mécanisme d'extraction de la machine, celle-ci doit toujours rester parfaitement visible par les spectateurs.Finally, for reasons related to the psychology of the lottery participants, it is essential that each player who attends the draw has no doubt about the origin of the ball extracted. In other words, as soon as a ball is grabbed, randomly, by the machine's extraction mechanism, the machine must always remain perfectly visible to the spectators.

Les machines existantes ne permettent pas de remplir ces trois critères de façon satisfaisante.Existing machines do not allow these three criteria to be satisfactorily fulfilled.

La machine de l'invention qui remédie à ces inconvénients est du genre de celles dans lesquelles les boules sont agitées par une soufflerie et elle est remarquable en ce que les boules sont placées dans un réceptacle sphérique et transparent,comportant une pluralité d'orifices de sortie d'air pulsé.The machine of the invention which overcomes these drawbacks is of the kind in which the balls are agitated by a blower and it is remarkable in that the balls are placed in a spherical and transparent receptacle, comprising a plurality of orifices of forced air outlet.

Les jets d'air ainsi produits sont dirigés obliquement par rapport à la verticale et à l'horizontale du lieu.The air jets thus produced are directed obliquely to the vertical and horizontal of the place.

Selon un autre mode de réalisation, la boule peut pénétrer dans un tube qui, à cet effet, présente un diamètre intérieur légèrement supérieur à celui des boules, et être évacuée par un orifice prévu à la partie inférieure du tube, des moyens étant prévus pour que l'introduction d'une boule dans le tube et d'une seule, se produise à l'instant désiré par l'utilisateur et, seulement, à cet instant.According to another embodiment, the ball can enter a tube which, for this purpose, has an inside diameter slightly greater than that of the balls, and be discharged through an orifice provided at the bottom of the tube, means being provided for that the introduction of a ball into the tube and only one, occurs at the instant desired by the user and, only, at this instant.

D'autres caractéristiques ressortiront mieux de la description qui va suivre, faite en se référant aux dessins annexés à titre d'exemple indicatif seulement, sur lesquels:

  • La figure 1 est une vue en coupe verticale d'une machine conforme à l'invention ;
  • La figure 2 est une vue partielle, à plus grande échelle et en perspective montrant,notamment, les orifices de sortie de l'air pulsé.
  • Les figures 3 et 4 sont des vues partielles montrant respectivement la machine en fonctionnement et l'extraction d'une boule;
  • La figure 5 est une vue partielle, en coupe, montrant un autre mode de réalisation de la machine conforme à l'invention;
  • La figure 6 est une vue, à plus grande échelle, du détail A de la figure 5;
  • La figure 7 est une vue, analogue à celle 6, complétée par la partie inférieure du tube mobile.
Other characteristics will emerge better from the description which follows, made with reference to the accompanying drawings by way of indicative example only, in which:
  • Figure 1 is a vertical sectional view of a machine according to the invention;
  • Figure 2 is a partial view, on a larger scale and in perspective showing, in particular, the outlet openings of the forced air.
  • Figures 3 and 4 are partial views respectively showing the machine in operation and the extraction of a ball;
  • Figure 5 is a partial view, in section, showing another embodiment of the machine according to the invention;
  • Figure 6 is a view, on a larger scale, of the detail A of Figure 5;
  • Figure 7 is a view, similar to that 6, supplemented by the lower part of the movable tube.

En se reportant aux dessins, on voit que les boules 1 sont placées dans un réceptacle 2 constitué par une sphère creuse et transparente, reposant sur un bâti 3.Referring to the drawings, it can be seen that the balls 1 are placed in a receptacle 2 constituted by a hollow and transparent sphere, resting on a frame 3.

La partie inférieure de la sphère 2 communique,par l'entremise de volets 4, avec un espace annulaire 5 dans lequel on envoie de l'air pulsé par l'intermédiaire d'un compresseur 6 logé dans le bâti 3.The lower part of the sphere 2 communicates, via flaps 4, with an annular space 5 in which pulsed air is sent by means of a compressor 6 housed in the frame 3.

L'espace annulaire 5 est délimité par une enveloppe tubu­laire 7 et par un tube central 8 dont l'utilité apparaîtra plus loin. Les volets 4 sont articulés chacun autour d'axes s'étendant radialement par rapport à l'espace 5.La commande de l'inclinaison des volets précités ne posant aucun problème particulier,celle-ci n'a pas été représentée; elle peut être manuelle ou télécommandée.The annular space 5 is delimited by a tubular casing 7 and by a central tube 8, the usefulness of which will appear later. The flaps 4 are each articulated around axes extending radially with respect to the space 5. The control of the inclination of the abovementioned flaps poses no particular problem, this has not been shown; it can be manual or remote-controlled.

Lorsque les volets 4 sont ouverts et tous inclinés dans le même sens et qu'on envoie de l'air pulsé, les boules 1 tournent dans la sphère 2 et sont soulevées.On constate alors que toutes les boules se placent selon un anneau diamètral, tel que celui montré en 9 sur la figure 3.When the flaps 4 are open and all inclined in the same direction and pulsed air is sent, the balls 1 rotate in the sphere 2 and are lifted. We then observe that all the balls are placed in a diametric ring, such as that shown at 9 in FIG. 3.

On a constaté, aussi, qu'en fermant certains volets adjacents, on pouvait placer les boules 1 selon un anneau tel que celui 10.It has also been found that by closing certain adjacent flaps, the balls 1 can be placed in a ring such as that 10.

Dans les deux cas, les boules formant les anneaux tournent et on obtient ainsi un effet scénique important qui se trouve accru si les boules présentent des couleurs différentes.In both cases, the balls forming the rings rotate and an important scenic effect is thus obtained which is increased if the balls have different colors.

L'expérience a montré que si le nombre de boules était supérieur à celui admissible pour former un anneau diamétral, lesdites boules se plaçaient spontanément selon deux anneaux parallèles.Experience has shown that if the number of balls was greater than that admissible to form a diametral ring, said balls spontaneously placed in two parallel rings.

On a constaté enfin que si on inversait l'inclinaison de l'un des volets, l'anneau formé par les boules basculait et tendait à se placer dans un plan vertical.Finally, it was found that if the inclination of one of the flaps was reversed, the ring formed by the balls tilted and tended to be placed in a vertical plane.

Le tube 8 est relié par une tubulure souple 11 à un aspira­teur 12 susceptible de créer une brusque dépression dans ledit tube. A l'instant où le tirage d'une boule doit être effectué, on interrompt l'envoi de l'air et, à ce moment, l'anneau "éclate" c'est-à-dire que toutes les boules qui étaient disposées selon cet anneau se déplacent de façon parfaitement imprévisible dans la sphère.The tube 8 is connected by a flexible tube 11 to a vacuum cleaner 12 capable of creating a sudden depression in said tube. At the moment when the drawing of a ball must be carried out, the air is interrupted and, at this moment, the ring "bursts", that is to say that all the balls which were placed according to this ring move in a perfectly unpredictable way in the sphere.

Selon l'invention, on profite de cette phase transitoire pour " capturer" une boule et, à cet effet, on crée une brusque dépression dans le tube 8 ce qui a pour effet d'aspirer la boule qui passe à promixité de l'orifice supérieur du tube 8.According to the invention, we take advantage of this transient phase to "capture" a ball and, for this purpose, we create a sudden depression in the tube 8 which has the effect of sucking the ball which passes near the orifice top of tube 8.

La boule capturée est fermement maintenue par la dépression et les chocs provoqués par les autres boules sont sans effet.The captured ball is firmly held by the depression and the shocks caused by the other balls have no effect.

A ce moment, on actionne, par exemple, un moto-réducteur 13 qui provoque le déplacement axial, selon la flèche F₁ du tube 8. Ce dernier pousse la boule capturée et l'extrait de la sphère, cette dernière présentant à cet effet, à sa partie supérieure, une ouverture 14 ( figure 1).At this moment, a motor-reducer 13 is actuated, which causes the axial displacement, along the arrow F₁ of the tube 8. The latter pushes the captured ball and extracts it from the sphere, the latter having for this purpose, at its upper part, an opening 14 (Figure 1).

L'ouverture 14 ayant nécessairement la section la plus réduite que possible,il est prévu, à la partie supérieure de la sphère, de petits orifices 15 de façon à ce que le débit d'air ne soit pas freiné.The opening 14 necessarily having the smallest section possible, there are provided at the upper part of the sphere, small orifices 15 so that the air flow is not slowed down.

Par mesure de sécurité l'ouverture 14 peut être partiellement obturée par des languettes souples (non représentées) s'opposant à l'éjection intempestive d'une boule mais s'escamotant sous l'action du tube 8.As a safety measure, the opening 14 can be partially closed by flexible tabs (not shown) opposing the untimely ejection of a ball but retracting under the action of the tube 8.

Naturellement, la machine peut être complétée par une goulotte transparente telle que celle 16, permettant d'évacuer la boule tirée à l'aide, par exemple, d'une soufflette non représentée ou d'un autre dispositif.Naturally, the machine can be supplemented by a transparent chute such as that 16, making it possible to evacuate the ball drawn using, for example, a blow gun not shown or another device.

Selon un autre mode de réalisation, on voit que les boules 1 sont placées dans un réceptacle 2,transparent, reposant sur un bâti 3(figure 5)According to another embodiment, we see that the balls 1 are placed in a receptacle 2, transparent, resting on a frame 3 (Figure 5)

La partie inférieure du réceptacle 2 communique par l'entremise de volets 4 avec un espace annulaire 5,délimité par une enveloppe tubulaire 7 et par un tube central 17,mobile axialement et dont le diamètre interne est légèrement supérieur à celui des boules 1.The lower part of the receptacle 2 communicates via flaps 4 with an annular space 5, delimited by an envelope tubular 7 and by a central tube 17, axially movable and whose internal diameter is slightly greater than that of the balls 1.

Le tube 17 présente, vers sa partie inférieure, un orifice latéral 18 susceptible de coïncider avec l'orifice d'entrée 19 d'une tubulure fixe 20 permettant d'évacuer les boules.The tube 17 has, towards its lower part, a lateral orifice 18 capable of coinciding with the inlet orifice 19 of a fixed tube 20 making it possible to evacuate the balls.

Le problème essentiel consiste à :
-empêcher les boules de pénétrer intempestivement dans le tube 17;
-maintenir, à un instant déterminé par l'utilisateur, une boule et une seule à la partie supérieure du tube ;
-évacuer cette boule.The main problem is:
prevent the balls from accidentally entering the tube 17;
-maintain, at a time determined by the user, a ball and only one at the top of the tube;
-evacuate this ball.

Ce résultat est obtenu en prévoyant, à la partie supérieure du tube, deux butées escamotables 21 et 22 susceptibles de faire saillie à l'intérieur du tube 17.This result is obtained by providing, at the upper part of the tube, two retractable stops 21 and 22 capable of projecting inside the tube 17.

La butée 21 est située au plus près de l'orifice d'entrée 17a du tube et elle s'oppose à la pénétration des boules dans le tube et même au maintien d'une boule à l'extrémité dudit tube.The stop 21 is located as close as possible to the inlet orifice 17 a of the tube and it opposes the penetration of the balls into the tube and even the maintenance of a ball at the end of said tube.

La butée 22 est située à une distance H de l'orifice 17a qui est telle que lorsqu'une boule est maintenue par ladite butée, le sommet de ladite boule affleure sensiblement l'extrémité du tube et s'oppose à la pénétration d'une autre boule et même, à son maintien (figure 7).The stop 22 is located at a distance H from the orifice 17 a which is such that when a ball is held by said stop, the top of said ball is substantially flush with the end of the tube and is opposed to the penetration of another ball and even, its maintenance (figure 7).

Lorsque les boules sont agitées dans le réceptacle 2, la butée 21 fait saillie dans le tube.When the balls are agitated in the receptacle 2, the stop 21 projects into the tube.

Pour capturer une boule, on crée une forte aspiration dans le tube 17 pour attirer une boule en regard de l'orifice 17a et, successivement, mais dans un laps de temps très bref, on escamote la butée 21 et on fait saillir celle 22.To capture a ball, we create a strong suction in the tube 17 to attract a ball opposite the orifice 17 a and, successively, but in a very short period of time, we retract the stop 21 and we protrude that 22 .

La boule capturée est ainsi bien visible à l'extrémité du tube qui est réalisé en une matière transparenteThe captured ball is thus clearly visible at the end of the tube which is made of a transparent material

Pour évacuer la boule, on escamote la butée et, simultanément, on fait saillir celle 21, la boule tombe et sort du tube par l'orifice 18.To evacuate the ball, the stop is retracted and, simultaneously, the one 21 protrudes, the ball falls and leaves the tube through the orifice 18.

Selon un mode d'utilisation de la machine, l'orifice 18 ne coïncide pas avec celui 19 de la tubulure 20.Ainsi, comme montré sur les dessins, il faut élever le tube pour faire coïncider les deux orifices, mais l'inverse est également possible.According to a mode of use of the machine, the orifice 18 does not coincide with that 19 of the tubing 20. Thus, as shown in the drawings, it is necessary to raise the tube to make the two orifices coincide, but the reverse is also possible.

Selon un mode de réalisation, les butées 21 et 22 forment les extrémités d'un levier 23,articulé, sensiblement en son milieu, sur un axe 24, ledit levier étant constamment soumis à l'action d'un ressort 25 qui force la butée 21 à faire saillie dans le tube 17.According to one embodiment, the stops 21 and 22 form the ends of a lever 23, articulated, substantially in the middle, on an axis 24, said lever being constantly subjected to the action of a spring 25 which forces the stop 21 to protrude into the tube 17.

Lorsque, par une action extérieure, on force le levier 23 à pivoter selon la flèche F₂ on détermine simultanément l'escamotage de la butée 21 et la sortie de celle 22.When, by an external action, the lever 23 is forced to pivot along the arrow F₂, the retraction of the stop 21 and the output of that 22 are simultaneously determined.

Une telle action peut être réalisée ,par exemple, à l'aide d'un câble 26, fixé sur la partie inférieure du levier 23, en un point qui est déporté vers l'extérieur par rapport à l'axe 24. La tension du câble peut être réalisée par tous moyens connus.Such an action can be carried out, for example, using a cable 26, fixed on the lower part of the lever 23, at a point which is offset towards the outside with respect to the axis 24. The tension of the cable can be produced by any known means.

Bien entendu, la présente invention ne se limite pas aux modes de réalisation décrits et représentés mais s'étend, au contraire, à toutes variantes de formes et dimensions.Of course, the present invention is not limited to the embodiments described and shown but extends, on the contrary, to all variants of shapes and dimensions.

C'est ainsi, par exemple, que le dispositif est complété par une butée déflectrice 27 qui dirige la boule à évacuer vers l'orifice 18.Thus, for example, the device is completed by a deflecting stop 27 which directs the ball to be discharged towards the orifice 18.
