La présente invention repose sur l'idée simple mais non moins inventive de prévoir une barrière de sécurité montée rotative autour d'un axe longitudinal, qui pivote sur elle-même si une personne, notamment un enfant, cherche à s'y agripper.The present invention is based on the simple but no less inventive idea to provide a security barrier rotatably mounted about a longitudinal axis, which pivots on itself if a person, including a child, tries to grip it.
En relation avec le problème de sécurité des enfants exposé plus haut, une application principale de l'invention est d'empêcher un enfant de monter sur le rebord d'une fenêtre. Une telle application est illustrée sur la figure 1, où l'on aperçoit un dispositif 10 selon l'invention agencé sur une baie 1 de fenêtre. Le dispositif 10 comprend un élément formant barrière 11 agencé horizontalement en travers de la baie et fixé à ses deux extrémités à des boîtiers muraux 15, 16 représentés ici apparents mais pouvant être intégrés dans le mur. L'élément formant barrière 11 est ici de forme cylindrique (des formes complexes peuvent toutefois être prévues) et présente de préférence un diamètre suffisant pour ne pas pouvoir être saisi à pleines mains par un enfant.In relation to the above-mentioned child safety problem, a main application of the invention is to prevent a child from climbing on a window sill. Such an application is illustrated in Figure 1, where we see a device 10 according to the invention arranged on a window bay 1. The device 10 comprises a barrier element 11 arranged horizontally across the bay and fixed at both ends to wall housings 15, 16 shown here visible but can be integrated into the wall. The barrier element 11 is here cylindrical in shape (complex shapes may however be provided) and preferably has a diameter sufficient to not be grasped by a child in full hands.
La figure 2 est une vue en coupe simplifiée de l'élément 11. Celui-ci est monté rotatif autour d'un axe longitudinal 12 et présente un sens de rotation autorisé Sl et un sens de rotation interdit S2. L'axe 12 représenté est un axe mathématique et n'est pas nécessairement un axe réel car, comme on le verra par la suite, l'obtention d'un tel axe de rotation ne nécessite généralement pas de prévoir un axe matériel traversant l'élément 11 de part en part.FIG. 2 is a simplified sectional view of the element 11. This element is rotatably mounted around a longitudinal axis 12 and has an allowed direction of rotation S1 and a forbidden direction of rotation S2. The axis 12 shown is a mathematical axis and is not necessarily a real axis because, as will be seen later, obtaining such an axis of rotation does not generally require to provide a material axis traversing the element 11 from side to side.
La rotation de l'élément 11 dans le sens Sl empêche un enfant de grimper sur la fenêtre en s'agrippant à l'élément 11. En effet, dans ce cas, l'élément 11 tourne dans le sens Sl et les mains de l'enfant sont renvoyées vers l'intérieur. En d'autres termes, l'élément 11 se "défausse" lorsqu'on cherche à s'y agripper.The rotation of the element 11 in the direction Sl prevents a child from climbing on the window by gripping the element 11. Indeed, in this case, the element 11 rotates in the direction Sl and the hands of the child. child are returned to the interior. In other words, the element 11 "discards" when one tries to grip it.
La prévision du sens de rotation interdit S2 se justifie pour des raisons de sécurité. En effet, en supposant qu'un enfant parvienne à grimper sur le rebord de la fenêtre sans s'agripper à l'élément formant barrière 11 et qu'il s'appuie ensuite sur celui-ci, le fait que l'élément 11 puisse tourner dans le sens de rotation S2 pourrait s'avérer très dangereux car l'enfant pourrait être entraîné vers l'avant. Toutefois, si la prévision du sens de rotation interdit S2 apparaît comme indispensable dans l'application décrite ici, elle peut n'être pas nécessaire voire n'être pas souhaitable dans d'autres applications dont certaines seront évoquées plus loin.The prediction of the direction of rotation forbidden S2 is justified for safety reasons. Indeed, assuming that a child manages to climb on the window sill without clinging to the barrier element 11 and then leans on it, the fact that the element 11 can turning in the direction of rotation S2 could be very dangerous as the child could be dragged forward. However, if the prediction of the direction of rotation prohibits S2 appears essential in the application described here, it may not be necessary or even be undesirable in other applications, some of which will be discussed later.
La rotation de l'élément 11 dans le sens Sl peut être une rotation libre ou une rotation forcée, c'est-à-dire avec intervention d'un moteur. La prévision d'un dispositif à rotation libre est avantageuse en terme de prix de revient et la prévision d'un dispositif à rotation forcée peut être avantageuse dans certains cas au plan de la sécurité. Par exemple, si le rebord de la fenêtre est bas relativement au sol et qu'un enfant peut facilement atteindre l'élément 11 au moyen d'une chaise ou en étant aidé par un autre enfant, l'enfant sera tôt ou tard amené à s'appuyer sur l'élément 11 en prenant le risque de passer par-dessus. Une solution à cette éventualité est donc de motoriser le dispositif de manière que l'élément 11 se mette à tourner dès qu'un appui est exercé, de sorte que l'enfant sera renvoyé vers l'intérieur. Une autre solution, décrite plus loin, est de surélever l'élément 11 autant que possible.The rotation of the element 11 in the direction Sl can be a free rotation or a forced rotation, that is to say with intervention of a motor. The provision of a device with free rotation is advantageous in terms of cost and the provision of a device for forced rotation can be advantageous in some cases in terms of safety. For example, if the window sill is low relative to the floor and a child can easily reach the element 11 by means of a chair or assisted by another child, the child will sooner or later be brought to rely on item 11 taking the risk of going over it. A solution to this eventuality is to motorize the device so that the element 11 starts to rotate as soon as a support is exercised, so that the child will be returned to the inside. Another solution, described later, is to raise element 11 as much as possible.
On décrira maintenant deux exemples de réalisation du dispositif, l'un à rotation libre, l'autre à rotation forcée. Il sera noté que ces exemples ne sont décrits qu'à titre purement exemplatif et non limitatif car il est en soi à la portée de l'homme de l'art de réaliser un cylindre rotatif (ou toute autre forme de l'élément formant barrière) motorisé ou non.We will now describe two embodiments of the device, one free rotation, the other forced rotation. It will be noted that these examples are described only by way of example and not limitation because it is within the reach of those skilled in the art to make a rotating cylinder (or any other form of the barrier element ) motorized or not.
Le dispositif 20 représenté en coupe sur la figure 3 est du type à rotation libre et comprend un élément formant barrière 11 ayant comme précédemment la forme d'un cylindre, un boîtier mural latéral gauche 22 et un boîtier mural latéral droite 23, et deux roulements 24, 25 qui relient respectivement les extrémités gauche et droite du cylindre 11 aux boîtiers latéraux 22, 23 correspondants.The device 20 shown in section in FIG. 3 is of the free rotation type and comprises a barrier element 11 having as before in the form of a cylinder, a left lateral wall box 22 and a right lateral wall box 23, and two bearings. 24, 25 which respectively connect the left and right ends of the cylinder 11 to the corresponding side housings 22, 23.
L'élément formant barrière 11 est ici un cylindre creux qui peut être en matière plastique ou en métal. Il peut être revêtu d'une couche antidérapante, tel un film de matière en caoutchouc» Son diamètre est par exemple de l'ordre de 10 à 30 cm.The barrier element 11 is here a hollow cylinder which may be plastic or metal. It can be coated with a non-slip layer, such as a film of rubber material. Its diameter is for example of the order of 10 to 30 cm.
Les roulements 24, 25 sont des roulements à un seul sens ("one way bearings"), par exemple des roulements à aiguilles d'un type courant dans le commerce. Leur structure est représentée très schématiquement en coupe dans un cercle en traits pointillés. Chaque roulement 24, 25 comprend une bague externe 200 et une bague interne 201 séparées par une gorge 202 dans laquelle est agencée une rangée d'aiguilles 203 qui permet à la bague externe 200 de tourner relativement à la bague interne 201 (ou vice-versa). Bien que la structure complète des roulements ne soit pas représentée, il sera rappelé que les aiguilles d'un roulement à un seul sens sont agencées dans une cage d'entretoisement qui comprend des logements recevant chacun une aiguille. Chaque logement de la cage d'entretoisement présente un premier bord où l'aiguille peut rouler librement et un second bord comportant une paroi inclinée qui coince l'aiguille et l'empêche de tourner librement. Une lame élastique pousse l'aiguille vers le premier bord mais lorsque le roulement est entraîné dans le sens de rotation interdit, l'aiguille se loge dans le second bord et se coince contre la paroi inclinée de sorte que le roulement ne peut pas tourner.The bearings 24, 25 are one-way bearings, for example needle bearings of a type commonly used in the trade. Their structure is shown very schematically in section in a dashed circle. Each bearing 24, 25 comprises an outer ring 200 and an inner ring 201 separated by a groove 202 in which is arranged a row of needles 203 which allows the outer ring 200 to rotate relative to the inner ring 201 (or vice versa ). Although the complete structure of the bearings is not shown, it will be recalled that the needles of a one-way bearing are arranged in a spacer cage which comprises housing each receiving a needle. Each housing of the spacer cage has a first edge where the needle can roll freely and a second edge having an inclined wall which wedges the needle and prevents it from rotating freely. An elastic blade pushes the needle towards the first edge but when the bearing is driven in the direction of rotation prohibited, the needle fits into the second edge and jams against the inclined wall so that the bearing can not rotate.
La bague externe 200 de chaque roulement 23, 24 est emmanchée dans l'extrémité correspondante du cylindre 11 où elle est maintenue par coincement ou par un moyen de fixation quelconque, par exemple une clavette ou une colle de fixation. La bague interne 201 de chaque roulement comporte un axe 204 formant moyeu qui s'étend axialement. L'axe 204 présente une extrémité 205 filetée (le filetage n'est pas représenté sur la figure) sur laquelle est vissée et bloquée (si nécessaire au moyen d'un contre-écrou) une pièce d'extrémité 206 de forme carrée ou polygonale.The outer ring 200 of each bearing 23, 24 is fitted into the corresponding end of the cylinder 11 where it is held by wedging or by means of any fastener, for example a key or a fixing glue. The inner ring 201 of each bearing has a hub axis 204 which extends axially. The axis 204 has a threaded end 205 (the thread is not shown in the figure) on which is screwed and locked (if necessary by means of a lock nut) a end piece 206 of square or polygonal shape .
Chaque boîtier mural 22, 23 (Cf. vue détaillée dans un cercle en traits pointillés) comprend un logement 210 de forme correspondante (carrée ou polygonale) qui reçoit la pièce d'extrémité 203, de sorte que la bague interne 201 du roulement est bloquée en rotation tandis que la bague externe 200 et le cylindre 11 solidaire de celle-ci peuvent tourner dans le sens de rotation autorisé par les roulements 23, 24.Each wall box 22, 23 (see detailed view in a dashed circle) comprises a housing 210 of corresponding shape (square or polygonal) which receives the end piece 203, so that the inner ring 201 of the bearing is blocked. in rotation while the outer ring 200 and the cylinder 11 secured thereto can rotate in the direction of rotation permitted by the bearings 23, 24.
Chaque boîtier mural 22, 23 comprend un logement 211 pour recevoir l'extrémité correspondante du cylindre 11, tant pour des raisons esthétiques que pour éviter qu'un enfant se pince les doigts entre les bords du cylindre et les boîtiers muraux. Chaque boîtier mural 22, 23 se présente en deux parties, à savoir une partie inférieure 220 comportant des orifices 212 de fixation du boîtier sur le mur, et une partie supérieure 221 qui vient coiffer la partie inférieure 220. Ainsi, après avoir fixé les boîtiers muraux, les extrémités du cylindre 11 et les pièces d'extrémité 206 sont engagées dans les logements 210, 211 en passant par le haut, puis les logements 210, 211 sont refermés en vissant la partie supérieure 221 sur la partie inférieure 220.Each wall housing 22, 23 comprises a housing 211 to receive the corresponding end of the cylinder 11, both for aesthetic reasons that to prevent a child pinches his fingers between the edges of the cylinder and the wall housings. Each wall box 22, 23 is in two parts, namely a lower portion 220 having holes 212 for fixing the housing on the wall, and an upper portion 221 which caps the lower part 220. Thus, after having fixed the housings wall, the ends of the cylinder 11 and the end pieces 206 are engaged in the housing 210, 211 through the top, then the housing 210, 211 are closed by screwing the upper part 221 on the lower part 220.
Il va de soi que divers autres types de roulements peuvent être utilisés, notamment des roulements à billes ou à cylindre. Par ailleurs, il est suffisant qu'un seul des roulements 24, 25 soit à sens unique pour empêcher le cylindre 11 de tourner dans le sens de rotation interdit. Egalement, une variante de réalisation sans roulement peut être prévue, en utilisant un axe de rotation comprenant un palier à coussinets lisses et un système anti-retour à cliquet pour empêcher le cylindre 11 de tourner dans le sens de rotation interdit. Il est ainsi possible de réaliser un dispositif de sécurité selon l'invention à faible prix de revient, commercialisable à un prix attractif pour inciter les parents à installer le dispositif sur toutes fenêtres potentiellement dangereuses pour les enfants.It goes without saying that various other types of bearings can be used, including ball bearings or cylinder. Furthermore, it is sufficient that only one of the bearings 24, 25 is one-way to prevent the cylinder 11 from rotating in the direction of rotation prohibited. Also, an alternative embodiment without a bearing can be provided, using a rotational axis comprising a plain bearing bearing and a ratchet non-return system to prevent the cylinder 11 from rotating in the direction of rotation prohibited. It is thus possible to achieve a safety device according to the invention at low cost, marketable at an attractive price to encourage parents to install the device on all windows potentially dangerous for children.
Le dispositif 30 représenté en coupe sur la figure 4 comprend en sus du précédent un moteur électrique 40 et un détecteur d'appui qui active le moteur 40 lorsqu'on s'appuie sur le cylindre 11.The device 30 shown in section in FIG. 4 comprises, in addition to the preceding one, an electric motor 40 and a bearing detector which activates the motor 40 when it is supported on the cylinder 11.
Le moteur 40 est disposé ici à l'intérieur du cylindre 11 et est plus particulièrement agencé dans un fourreau 50 ayant une enveloppe cylindrique qui est logée à l'intérieur du cylindre 11, le cylindre 11 étant libre de tourner autour fourreau 50. A l'arrière du moteur 40, correspondant ici à l'extrémité droite du cylindre 11, le fourreau 50 présente une terminaison 51 de section carrée ou polygonale qui s'étend en dehors du cylindre 11. A l'avant du moteur 40, le fourreau 50 reçoit également un réducteur planétaire 41 formant avec le moteur 40 un motoréducteur d'un type disponible dans le commerce sous forme de composant standard. A l'avant du réducteur 41 se trouve l'axe 42 du motoréducteur qui s'étend au-delà du fourreau 50 et est couplé à un galet 43 d'entraînement du cylindre 11. Le cylindre 11 est rendu solidaire en rotation du galet 43 par une goupille 44 qui traverse le cylindre et le galet. A l'extrémité droite du cylindre 11, se trouve un boîtier mural latéral droit 60 qui comporte un logement 61 de réception de la terminaison 51 du fourreau 50, de même forme que celle-ci. Ainsi, le logement 61 empêche le fourreau 50 et par conséquent le moteur 40 de tourner autour d'eux-mêmes. Le boîtier mural 60 est coiffé par une partie supérieure amovible 62 suivant le principe décrit plus haut, la partie 62 étant vissée sur le boîtier 60 pour fermer le logement 61 après que la terminaison 51 du fourreau 50 a été engagée dans le logement 61.The motor 40 is disposed here inside the cylinder 11 and is more particularly arranged in a sleeve 50 having a cylindrical envelope which is housed inside the cylinder 11, the cylinder 11 being free to rotate around the sleeve 50. rear of the engine 40, corresponding here to the right end of the cylinder 11, the sleeve 50 has a termination 51 of square or polygonal section which extends outside the cylinder 11. At the front of the engine 40, the sleeve 50 also receives a planetary gear 41 forming with the motor 40 a geared motor of a type commercially available as a standard component. At the front of the gearbox 41 is the axis 42 of the geared motor which extends beyond the sleeve 50 and is coupled to a roller 43 for driving the cylinder 11. The cylinder 11 is made integral in rotation with the roller 43 by a pin 44 which passes through the cylinder and the roller. At the right end of the cylinder 11, there is a right lateral wall housing 60 which has a housing 61 for receiving the end 51 of the sleeve 50, of the same shape as this one. Thus, the housing 61 prevents the sleeve 50 and therefore the motor 40 from rotating around themselves. The wall box 60 is capped by a removable upper portion 62 according to the principle described above, the portion 62 being screwed on the housing 60 to close the housing 61 after the termination 51 of the sleeve 50 has been engaged in the housing 61.
A l'extrémité gauche du cylindre 11 se trouve un système de fixation identique à celui du dispositif 20 précédemment décrit, comprenant le boîtier mural 22 déjà décrit, dont les références sont conservées, ainsi que le roulement 24 emmanché dans le cylindre 11, qui s'engage dans le boîtier mural 22 de la manière déjà décrite.At the left end of the cylinder 11 is a fastening system identical to that of the device 20 previously described, comprising the wall housing 22 already described, whose references are retained, and the bearing 24 fitted into the cylinder 11, which engages in the wall box 22 in the manner already described.
La figure 5A représente de façon plus détaillée la structure du boîtier mural latéral droit 60. La fonction d'alimentation électrique du moteur et la fonction de détection des appuis sur le cylindre 11 sont réalisées ici par un système commun aux deux fonctions qui comprend un ressort à spires 70, une bille 71, deux balais électriquement conducteurs 72, 72' et deux lames métalliques 73, 73'.FIG. 5A shows in more detail the structure of the right side wall box 60. The power supply function of the motor and the function of detecting the supports on the cylinder 11 are realized here by a system common to both functions which comprises a spring 70, a ball 71, two electrically conductive brushes 72, 72 'and two metal blades 73, 73'.
La partie basse du logement 61 comporte un orifice vertical dans lequel le ressort 70 et la bille 71 sont disposés. La terminaison 51 du fourreau 50 est en appui sur la bille 71 qui, sous l'effet du ressort, forme une sorte de suspension qui s'enfonce lorsqu'un appui est exercé sur le cylindre 11.The lower part of the housing 61 has a vertical orifice in which the spring 70 and the ball 71 are arranged. The end 51 of the sheath 50 is supported on the ball 71 which, under the effect of the spring, forms a kind of suspension which sinks when a support is exerted on the cylinder 11.
Les balais 72, 72' sont solidaires du flasque arrière du moteur 40 et sont reliés électriquement au moteur. Ils s'étendent horizontalement dans le logement 61 et leurs extrémités se trouvent en regard et sensiblement au-dessus des extrémités distales des lames métalliques 73, 73', qui sont également horizontales. Les lames 73, 73' sont coudées et présentent chacune une partie proximale verticale qui est fixée sur une paroi arrière 64 de la cavité 61, les parties proximales étant isolées l'une de l'autre par une rondelle 74 électriquement isolante. Des conducteurs traversent la paroi arrière 64 et relient électriquement les lames 73, 73' à des languettes 75, 75' qui s'étendent dans une cavité 65 située derrière la cloison 64. Lors du montage du dispositif, les languettes 75, 75' sont reliées à des fils d'alimentation électriquement et reçoivent une tension d'alimentation électrique du moteur.The brushes 72, 72 'are integral with the rear flange of the motor 40 and are electrically connected to the motor. They extend horizontally in the housing 61 and their ends are opposite and substantially above the distal ends of the metal blades 73, 73 ', which are also horizontal. The blades 73, 73 'are bent and each have a vertical proximal portion which is fixed on a rear wall 64 of the cavity 61, the proximal portions being isolated from each other by an electrically insulating washer 74. Conductors pass through the rear wall 64 and electrically connect the blades 73, 73 'to tongues 75, 75' which extend into a cavity 65 located behind the partition 64. During assembly of the device, the tongues 75, 75 'are connected to power supply wires electrically and receive a power supply voltage of the engine.
La figure 5B illustre le fonctionnement du système de détection d'appui. Lorsqu'un appui est exercé sur le cylindre 11, le jeu mécanique conféré au cylindre à son autre extrémité lui permet de s'incliner un petit peu en enfonçant la bille 71 dans son logement, comme représenté. Le balai 72 vient au contact de la lame 73 et le balai 72' vient au contact de la lame 73'. Le moteur 40 est alors alimenté électriquement, entraînant ainsi le cylindre dans le sens de rotation autorisé. A noter que le système est très sensible et que le débattement vertical de la bille est faible, ainsi que la distance entre les balais 72, 72' et les lames 73, 73', de préférence de l'ordre du millimètre. Ainsi, si une personne et notamment un enfant s'appuie un tant soi peu sur le cylindre 11, celui-ci se met immédiatement à tourner. La vitesse de rotation est de préférence faible, par exemple de l'ordre de 10 tours par minute. II apparaîtra clairement à l'homme de l'art que le dispositif qui vient d'être décrit est susceptible de diverses variantes de réalisation et perfectionnements. Notamment, en figure 4, l'extrémité gauche du cylindre 11 peut être équipée d'un système de détection d'appui identique à celui qui se trouve à son extrémité droite, avec les contacts connectés au moteur en parallèle avec ceux qui se trouvent dans la partie droite. Une telle double détection symétrique est notamment envisageable lorsque le cylindre présente une grande longueur (par exemple plus d'un mètre et jusqu'à plusieurs mètres de long).Figure 5B illustrates the operation of the support detection system. When a support is exerted on the cylinder 11, the mechanical play imparted to the cylinder at its other end allows it to tilt a little bit by depressing the ball 71 in its housing, as shown. The brush 72 comes into contact with the blade 73 and the brush 72 'comes into contact with the blade 73'. The motor 40 is then powered electrically, thus driving the cylinder in the direction of rotation allowed. Note that the system is very sensitive and the vertical movement of the ball is low, as well as the distance between the brushes 72, 72 'and the blades 73, 73', preferably of the order of one millimeter. Thus, if a person and especially a child relies a little bit on the cylinder 11, it starts immediately to turn. The rotation speed is preferably low, for example of the order of 10 revolutions per minute. It will be clear to those skilled in the art that the device which has just been described is capable of various alternative embodiments and improvements. In particular, in FIG. 4, the left end of the cylinder 11 may be equipped with a support detection system identical to that at its right end, with the contacts connected to the motor in parallel with those which are in the right part. Such symmetrical double detection is particularly conceivable when the cylinder has a great length (for example more than one meter and up to several meters long).
Comme autre perfectionnement, le galet d'entraînement 43 peut être remplacé par un roulement à un seul sens qui assure le couplage en rotation du cylindre 11 et de l'axe 42 du moteur, tout en permettant au cylindre 11 de tourner librement dans le sens autorisé, en cas de panne du moteur ou de panne d'alimentation électrique.As another improvement, the drive roller 43 can be replaced by a one-way bearing which rotates the cylinder 11 and the motor shaft 42, while allowing the cylinder 11 to rotate freely in the direction authorized, in case of engine failure or power failure.
Egalement, le système de détection d'appui peut être utilisé pour déclencher une alarme sonore, offrant ainsi un degré de sécurisé supplémentaire. Ainsi, le système de détection d'appui peut aussi être intégré dans le mode de réalisation à rotation libre décrit en relation avec la figure 3, uniquement pour déclencher une alarme.Also, the support detection system can be used to trigger an audible alarm, thus providing an additional degree of security. Thus, the support detection system can also be integrated in the free rotation embodiment described in connection with Figure 3, only to trigger an alarm.
L'élément rotatif formant barrière peut présenter diverses formes, y compris des formes de fantaisie, par exemple une section en forme d'étoile, de triangle, etc..The rotary barrier element may have various shapes, including fancy shapes, for example a star-shaped, triangle-shaped section, etc.
Par ailleurs, au lieu d'être à libre rotation selon le sens autorisé ou selon les deux sens de rotation possibles ("libre rotation" signifiant qu'il peut tourner plusieurs fois sur lui-même) l'élément peut être agencé de manière à seulement pivoter autour de son axe longitudinal selon un angle de rotation limité, par exemple 180°, et être équipé d'un ressort de rappel dans sa position angulaire originelle. Pour des raisons de sécurité, la vitesse angulaire de rappel élastique de l'élément pivotant est de préférence lente et le rappel de l'élément dans la position de repos est effectué avec une force de rappel faible.Furthermore, instead of being free rotation in the allowed direction or in the two possible directions of rotation ("free rotation" meaning that it can rotate several times on itself) the element can be arranged to only rotate about its longitudinal axis at a limited angle of rotation, for example 180 °, and be equipped with a return spring in its original angular position. For safety reasons, the angular speed of elastic return of the pivoting element is preferably slow and the return of the element in the rest position is performed with a low restoring force.
Le dispositif selon l'invention est également susceptible de diverses applications et agencements.The device according to the invention is also capable of various applications and arrangements.
La figure 6 illustre une variante de l'agencement représenté sur la figure 1 dans laquelle la baie 1 de fenêtre est basse par rapport au sol et dans lequel des barrières 13, 14 conventionnelles sont agencées entre le cylindre 11 selon l'invention et le rebord de la fenêtre. Ces barrières 13, 14 peuvent par ailleurs être remplacées par des rouleaux selon l'invention, pour former une barrière infranchissable formée par une pluralité de rouleaux pivotants empilés les uns sur les autres.FIG. 6 illustrates a variant of the arrangement shown in FIG. 1 in which the window bay 1 is low with respect to the ground and in which conventional barriers 13, 14 are arranged between the cylinder 11 according to the invention and the rim from the window. These barriers 13, 14 may also be replaced by rollers according to the invention, to form an impassable barrier formed by a plurality of pivoting rollers stacked on each other.
La figure 7 illustre une application où un cylindre 11 selon l'invention est agencé en haut d'un mur 17, pour empêcher des intrus de franchir le mur. Le cylindre 11 présente de préférence un diamètre sensiblement égal à l'épaisseur du mur 17, et peut être à rotation libre dans les deux sens, à titre dissuasif, cela rendant son franchissement hasardeux avec risque de chute de l'autre coté du mur.Figure 7 illustrates an application where a cylinder 11 according to the invention is arranged at the top of a wall 17, to prevent intruders from crossing the wall. The cylinder 11 preferably has a diameter substantially equal to the thickness of the wall 17, and can be freely rotated in both directions, as a deterrent, which makes its crossing risky with the risk of falling on the other side of the wall.
La figure 8 illustre une application à la réalisation de barrières périphériques pour la protection des abords de piscines, de préférence en utilisant le mode de réalisation à rotation libre qui est peu coûteux à réaliser et permet de fabriquer des barrières de grande longueur à moindre coût. Par exemple, une unité de barrière élémentaire telle que représentée comprend quatre cylindres à rotation libre d'un diamètre de 20 cm, agencés les uns au-dessus des autres avec un intervalle de l'ordre de 10 cm entre chaque cylindre et en laissant 10 cm entre le sol et le cylindre le plus bas, soit une barrière d'une hauteur de 120 cm quasiment infranchissable pour un enfant (la hauteur minimale selon la norme française étant de 1,10 m en ce qui concerne les barrières de protection de l'accès aux piscines privées). Dans une telle application, la prévision d'un seul sens de rotation peut être considérée comme moins cruciale, et peut éventuellement être abandonnée pour réaliser des barrières à cylindres à faible prix de revient. De même, la rotation des cylindres peut être assurée par des axes à palier lisse peu coûteux à réaliser, et l'ensemble du dispositif peut ne comprendre que des matériaux plastiques résistants aux intempéries.FIG. 8 illustrates an application to the production of peripheral barriers for the protection of swimming pool approaches, preferably using the free rotation embodiment which is inexpensive to produce and makes it possible to manufacture barriers of great length at a lower cost. For example, an elementary barrier unit as shown includes four free-rolling cylinders with a diameter of 20 cm, arranged one above the other with an interval of the order of 10 cm between each cylinder and leaving 10 cm between the ground and the lowest cylinder, either a barrier of a height of 120 cm almost impassable for a child (the minimum height according to the French standard being 1.10 m with regard to the barriers of protection of access to private pools). In such an application, the prediction of a single direction of rotation may be considered less crucial, and may possibly be abandoned to achieve low cost cylinder barriers. Likewise, the rotation of the rolls can be ensured by inexpensive sliding bearings to be carried out, and the entire device can comprise only weather-resistant plastic materials.
Bien entendu, et comme représenté en figure 9, une barrière de piscine selon l'invention peut également comprendre une barrière conventionnelle (par exemple en lieu et place des trois cylindres inférieurs) surmontée par un élément 11 pivotant ou rotatif selon l'invention qui empêche son franchissement. Of course, and as represented in FIG. 9, a swimming pool barrier according to the invention may also comprise a conventional barrier (for example in place of the three lower rolls) surmounted by a pivoting or rotating element 11 according to the invention which prevents his crossing.
