Definitions

  • the present invention relates to a device for opening a swimming pool enclosure.
  • a telescopic swimming pool enclosure comprises a plurality of modules.
  • One of the modules is fixed relative to the swimming pool, and each other module is movable in translation relative to the fixed module.
  • the swimming pool enclosure can be placed in a closed configuration, in which the modules are deployed so as to cover together a swimming pool, and an open configuration in which the modules are retracted into each other, so as to reveal the swimming pool.
  • telescopic swimming pool enclosures comprising an automatic opening device, comprising a wheel resting on the ground and a gear motor driving the wheel in rotation, so as to automatically tilt the telescopic enclosure from the configuration closed to open configuration.
  • the automatic opening device is an integral part of the swimming pool enclosure, and is arranged so as to be as invisible as possible when the enclosure is closed.
  • swimming pool enclosures may be sold without such an automatic opening device. These pool enclosures are opened manually.
  • a modular opening device could be envisaged in the form of an independent element which can be attached to a manually opened enclosure already installed on a pool.
  • Another difficulty resides in the fact that an automatic opening device fixed to a module of the shelter can come into abutment against another module of the shelter with the consequence of prematurely blocking the opening of the shelter. The shelter can then only be partially opened.
  • An object of the invention is to provide a device for retracting a telescopic structure which is not excessively visible when this structure is deployed, and which does not substantially limit the retraction travel of this structure.
  • the elongated nature and the mobility in rotation of the casing makes it possible to vary the horizontal bulk and the vertical bulk of the casing.
  • the vertical size of the box decreases.
  • the horizontal bulk of the box decreases, the vertical bulk of the box increases.
  • a swimming pool enclosure is a structure whose dimensions in a horizontal plane (length, width) are much greater than its height. Consequently, when the vertical size of the housing is reduced, the housing is less visible to someone located a few meters from the swimming pool.
  • the wheel can move in translation over a greater distance, which promotes opening of the shelter over a greater stroke.
  • the elongated shape of the box and its mobility in rotation makes it possible to reconcile the objectives consisting of reducing the reduction in visibility of the device and of not limiting the opening stroke of the shelter.
  • the device may also include the following optional features, taken alone or in combination when it makes technical sense.
  • the housing has an elongated shape along a longitudinal axis, and the housing is rotatable relative to the fixing element, when the fixing element is fixed to the telescopic structure, in a vertical position. in which the axis is perpendicular to the direction of translation, and in an inclined position.
  • the vertical position has the advantage of allowing the box to reduce the horizontal bulk of the box to a minimum. As a result, the wheel can move in translation over a greater distance, which maximizes the opening stroke of the shelter.
  • the longitudinal axis of the casing forms an angle of less than 45 degrees with respect to the direction of translation when the casing is in the tilted position.
  • Such an inclined position has the advantage of making the housing particularly inconspicuous for someone located a few meters from the swimming pool.

  • the casing has a flat support surface inclined with respect to the direction of translation so as to be simultaneously opposite the ground and the second module when the casing is in the inclined position.
  • the device comprises at least one stop arranged to limit the rotational travel of the casing relative to the fixing element when the fixing element is fixed to the telescopic structure, so as to prevent the casing from touching the ground.

Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne un dispositif pour ouvrir un abri de piscine.The present invention relates to a device for opening a swimming pool enclosure.

ETAT DE LA TECHNIQUESTATE OF THE ART

Conventionnellement, un abri de piscine télescopique comprend une pluralité de modules. L'un des modules est fixe par rapport à la piscine, et chaque autre module est mobile en translation par rapport au module fixe. L'abri de piscine peut être placée dans une configuration fermée, dans laquelle les modules sont déployés de manière à recouvrir ensemble une piscine, et une configuration ouverte dans laquelle les modules sont rétractés les uns dans les autres, de manière à dévoiler la piscine.Conventionally, a telescopic swimming pool enclosure comprises a plurality of modules. One of the modules is fixed relative to the swimming pool, and each other module is movable in translation relative to the fixed module. The swimming pool enclosure can be placed in a closed configuration, in which the modules are deployed so as to cover together a swimming pool, and an open configuration in which the modules are retracted into each other, so as to reveal the swimming pool.

On connaît de l'état de la technique des abris de piscine télescopiques comprenant un dispositif d'ouverture automatique, comprenant une roue reposant sur le sol et un motoréducteur entraînant en rotation la roue, de sorte faire basculer automatiquement l'abri télescopique de la configuration fermée à la configuration ouverte.Known from the state of the art are telescopic swimming pool enclosures comprising an automatic opening device, comprising a wheel resting on the ground and a gear motor driving the wheel in rotation, so as to automatically tilt the telescopic enclosure from the configuration closed to open configuration.

Généralement, le dispositif d'ouverture automatique fait partie intégrante de l'abri de piscine, et est agencé de manière à être le moins visible possible lorsque l'abri est fermé.Generally, the automatic opening device is an integral part of the swimming pool enclosure, and is arranged so as to be as invisible as possible when the enclosure is closed.

Toutefois, certains abris de piscine peuvent être vendus sans un tel dispositif d'ouverture automatique. Ces abris de piscine sont ouverts manuellement.However, some swimming pool enclosures may be sold without such an automatic opening device. These pool enclosures are opened manually.

Pour convertir un abri de piscine à ouverture manuelle en abri de piscine à ouverture automatique, il pourrait être envisagé un dispositif d'ouverture modulaire se présentant sous la forme d'un élément indépendant pouvant être fixé à un abri à ouverture manuelle déjà installé sur une piscine.To convert a manually opened swimming pool enclosure into an automatically opened swimming pool enclosure, a modular opening device could be envisaged in the form of an independent element which can be attached to a manually opened enclosure already installed on a pool.

Pour rendre ce dispositif modulaire invisible, celui-ci pourrait être fixé à l'intérieur de l'abri. Toutefois, il existe des abris de piscine dont la forme ne permet pas de réaliser un tel agencement.To make this modular device invisible, it could be fixed inside the shelter. However, there are pool enclosures whose shape does not allow such an arrangement to be made.

Une autre difficulté réside dans le fait qu'un dispositif d'ouverture automatique fixé sur un module de l'abri peut entrer en buter contre un autre module de l'abri avec pour conséquence bloquer prématurément l'ouverture de l'abri. L'abri ne peut alors n'être que partiellement ouvert.Another difficulty resides in the fact that an automatic opening device fixed to a module of the shelter can come into abutment against another module of the shelter with the consequence of prematurely blocking the opening of the shelter. The shelter can then only be partially opened.

EXPOSE DE L'INVENTIONDISCLOSURE OF THE INVENTION

Un but de l'invention est de proposer un dispositif pour rétracter une structure télescopique qui ne soit pas excessivement visible lorsque cette structure est déployée, et qui ne limite pas de manière substantielle la course de rétractation de cette structure.An object of the invention is to provide a device for retracting a telescopic structure which is not excessively visible when this structure is deployed, and which does not substantially limit the retraction travel of this structure.

Il est à cet effet proposé un dispositif pour rétracter une structure télescopique telle qu'un abri de piscine, le dispositif comprenant :

  • un élément de fixation propre à être fixé à la structure télescopique,
  • une roue montée à rotation sur l'élément de fixation, et propre à reposer sur un sol lorsque l'élément de fixation est fixé à la structure télescopique,
  • un moteur pour entraîner la roue en rotation par rapport à l'élément de fixation lorsque l'élément de fixation est fixé à la structure télescopique, de sorte à translater l'élément de fixation par rapport au sol dans une direction de translation, et ainsi entraîner une rétractation de la structure télescopique,
  • un boîtier contenant le moteur, le boîtier présentant une forme allongée le long d'un axe longitudinal, le boîtier étant mobile en rotation par rapport à l'élément de fixation, lorsque l'élément de fixation est fixé à la structure télescopique.
To this end, a device is proposed for retracting a telescopic structure such as a swimming pool enclosure, the device comprising:
  • a fixing element adapted to be fixed to the telescopic structure,
  • a wheel rotatably mounted on the fixing element, and capable of resting on the ground when the fixing element is fixed to the telescopic structure,
  • a motor for driving the wheel in rotation relative to the fixing element when the fixing element is fixed to the telescopic structure, so as to translate the fixing element relative to the ground in a direction of translation, and so cause retraction of the telescopic structure,
  • a casing containing the motor, the casing having an elongated shape along a longitudinal axis, the casing being rotatable relative to the fixing element, when the fixing element is fixed to the telescopic structure.

Le caractère allongé et la mobilité en rotation du boîtier permet de faire varier l'encombrement horizontal et l'encombrement vertical du boîtier. Lorsque l'encombrement horizontal du boîtier augmente, l'encombrement vertical du boîtier diminue. Inversement, lorsque l'encombrement horizontal du boîtier diminue, l'encombrement vertical du boîtier augmente.The elongated nature and the mobility in rotation of the casing makes it possible to vary the horizontal bulk and the vertical bulk of the casing. When the horizontal size of the box increases, the vertical size of the box decreases. Conversely, when the horizontal bulk of the box decreases, the vertical bulk of the box increases.

Un abri de piscine est une structure dont les dimensions dans un plan horizontal (longueur, largeur) sont bien plus élevées que sa hauteur. En conséquence, lorsque l'encombrement vertical du boîtier est réduit, le boîtier est moins visible pour quelqu'un situé à quelques mètres de la piscine.A swimming pool enclosure is a structure whose dimensions in a horizontal plane (length, width) are much greater than its height. Consequently, when the vertical size of the housing is reduced, the housing is less visible to someone located a few meters from the swimming pool.

A contrario, lorsque l'encombrement horizontal du boîtier est réduit, la roue peut se déplacer en translation sur une plus grande distance, ce qui favorise une ouverture de l'abri sur une course plus grande.Conversely, when the horizontal size of the housing is reduced, the wheel can move in translation over a greater distance, which promotes opening of the shelter over a greater stroke.

Ainsi, la forme allongée du boîtier et sa mobilité en rotation permet de concilier les objectifs consistant à réduire la réduction de visibilité du dispositif et de non limitation de la course d'ouverture de l'abri.Thus, the elongated shape of the box and its mobility in rotation makes it possible to reconcile the objectives consisting of reducing the reduction in visibility of the device and of not limiting the opening stroke of the shelter.

Le dispositif peut également comprendre les caractéristiques optionnelles suivantes, prises seules ou combinées entre elles lorsque cela fait sens techniquement.The device may also include the following optional features, taken alone or in combination when it makes technical sense.

De préférence, le boîtier présente une forme allongée le long d'un axe longitudinal, et le boîtier est mobile en rotation par rapport à l'élément de fixation, lorsque l'élément de fixation est fixé à la structure télescopique, dans une position verticale dans laquelle l'axe est perpendiculaire à la direction de translation, et dans une position inclinée.Preferably, the housing has an elongated shape along a longitudinal axis, and the housing is rotatable relative to the fixing element, when the fixing element is fixed to the telescopic structure, in a vertical position. in which the axis is perpendicular to the direction of translation, and in an inclined position.

La position verticale présente l'avantage de permettre au boîtier de réduire l'encombrement horizontal du boîtier au minimum. En conséquence, la roue peut se déplacer en translation sur une plus grande distance, ce qui maximise la course d'ouverture de l'abri.The vertical position has the advantage of allowing the box to reduce the horizontal bulk of the box to a minimum. As a result, the wheel can move in translation over a greater distance, which maximizes the opening stroke of the shelter.

De préférence, l'axe longitudinal du boîtier forme un angle inférieur à 45 degrés par rapport à la direction de translation lorsque le boîtier est dans la position inclinée. Une telle position inclinée a pour avantage de rendre le boîtier particulièrement peu visible pour quelqu'un situé à quelques mètres de la piscine.Preferably, the longitudinal axis of the casing forms an angle of less than 45 degrees with respect to the direction of translation when the casing is in the tilted position. Such an inclined position has the advantage of making the housing particularly inconspicuous for someone located a few meters from the swimming pool.

De préférence, l'axe de rotation du boîtier par rapport à l'élément de fixation et l'axe de rotation de la roue par rapport à l'élément de fixation sont parallèles, voire confondus.Preferably, the axis of rotation of the housing with respect to the fixing element and the axis of rotation of the wheel with respect to the fixing element are parallel, or even coincident.

De préférence, l'élément de fixation est propre à être fixé à un premier module de la structure télescopique, et le boîtier présente une forme adaptée pour qu'au cours de la translation de l'élément de fixation par rapport au sol, le boîtier dans la position inclinée prenne appui sur un deuxième module de la structure télescopique mobile en translation par rapport au premier module, puis soit sollicité par le deuxième module depuis la position inclinée vers la position verticale par le deuxième module.Preferably, the fixing element is capable of being fixed to a first module of the telescopic structure, and the casing has a shape adapted so that during the translation of the fixing element relative to the ground, the casing in the inclined position bears on a second module of the telescopic structure movable in translation relative to the first module, then is urged by the second module from the inclined position to the vertical position by the second module.

De préférence, le boîtier présente une surface d'appui plane inclinée par rapport à la direction de translation de manière à être simultanément en regard du sol et du deuxième module lorsque le boîtier est dans la position inclinée.Preferably, the casing has a flat support surface inclined with respect to the direction of translation so as to be simultaneously opposite the ground and the second module when the casing is in the inclined position.

De préférence, le dispositif comprend au moins une butée agencée pour limiter la course de rotation du boîtier par rapport à l'élément de fixation lorsque l'élément de fixation est fixé à la structure télescopique, de sorte à empêcher que le boîtier ne touche le sol.Preferably, the device comprises at least one stop arranged to limit the rotational travel of the casing relative to the fixing element when the fixing element is fixed to the telescopic structure, so as to prevent the casing from touching the ground.

De préférence, le dispositif comprend un réducteur mécanique pour transmettre un couple du moteur à la roue.Preferably, the device comprises a mechanical reduction gear to transmit a torque from the motor to the wheel.

De préférence, le moteur comprend un arbre moteur parallèle à l'axe longitudinal, l'arbre moteur étant couplé au réducteur mécanique par un renvoi d'angle.Preferably, the motor comprises a motor shaft parallel to the longitudinal axis, the motor shaft being coupled to the mechanical reduction gear by a bevel gear.

De préférence, le réducteur mécanique comprend un train d'engrenages à axes parallèles à l'intérieur du boîtier, le train d'engrenages comprenant une roue dentée reliée à la roue par un arbre de sortie débouchant à l'extérieur du boîtier.Preferably, the mechanical reducer comprises a gear train with parallel axes inside the casing, the gear train comprising a toothed wheel connected to the wheel by an output shaft emerging outside the casing.

De préférence, l'élément de fixation comprend deux fourreaux sur lesquels la roue est montée à rotation, et une base reliant mutuellement les deux fourreaux, l'un des deux fourreaux étant agencé entre la roue et le boîtier.Preferably, the fixing element comprises two sheaths on which the wheel is rotatably mounted, and a base mutually connecting the two sheaths, one of the two sheaths being arranged between the wheel and the housing.

De préférence, le boîtier est adapté pour être déplacé manuellement de la position inclinée à la position verticale, par rapport à l'élément de fixation.Preferably, the housing is adapted to be moved manually from the inclined position to the vertical position, with respect to the fixing element.

Il est également proposé, selon un autre aspect, un système comprenant une structure télescopique telle qu'un abri de piscine, et le dispositif susmentionné pour rétracter cette structure.There is also proposed, according to another aspect, a system comprising a telescopic structure such as a swimming pool enclosure, and the aforementioned device for retracting this structure.

De préférence, la structure télescopique comprend un premier module auquel le dispositif est fixé, et un deuxième module mobile en translation par rapport au premier module, le premier module étant propre à se rétracter à l'intérieur du deuxième module.Preferably, the telescopic structure comprises a first module to which the device is fixed, and a second module movable in translation relative to the first module, the first module being able to retract inside the second module.

DESCRIPTION DETAILLE D'AU MOINS UN MODE DE REALISATIONDETAILED DESCRIPTION OF AT LEAST ONE EMBODIMENT

On a représenté sur les figures 1 à 5 un système comprenant un dispositif 1 et une structure télescopique 2 formant un abri de piscine.We represented on the figures 1 to 5 a system comprising a device 1 and a telescopic structure 2 forming a swimming pool enclosure.

La structure télescopique 2 comprend une pluralité de modules, dont un module 4 dit « module fixe » car destiné à fixe par rapport à une piscine, et au moins un autre module mobile en translation par rapport au module fixe dans une direction de translation parallèle à un axe X.The telescopic structure 2 comprises a plurality of modules, including a module 4 called "fixed module" because intended to be fixed relative to a swimming pool, and at least one other module movable in translation relative to the fixed module in a direction of translation parallel to an X axis.

De manière générale, la structure télescopique 2 peut être placée dans une configuration fermée, dans laquelle les modules sont déployés de manière à recouvrir ensemble une piscine, et une configuration ouverte dans laquelle les modules sont rétractés les uns dans les autres, de manière à dévoiler la piscine.In general, the telescopic structure 2 can be placed in a closed configuration, in which the modules are deployed so as to cover together a swimming pool, and an open configuration in which the modules are retracted into each other, so as to reveal the swimming pool.

Le module 4 fixe par rapport à la piscine est un module extérieur dans lequel chaque autre module est apte à se rétracter.Module 4 fixed with respect to the swimming pool is an exterior module into which each other module is capable of retracting.

Dans le mode de réalisation représenté sur les figures 1 à 5, le nombre de module de la structure télescopique 2 est de quatre. Outre le module fixe 4, la pluralité de modules comprend un module mobile extrémal 6, un premier module intermédiaire 8 dans lequel le module mobile extrémal 4 est apte à se rétracter, un deuxième module intermédiaire 10 dans lequel le premier module intermédiaire 8 est apte à se rétracter, le deuxième module intermédiaire 10 étant lui-même apte à se rétracter dans le module fixe 4. Bien entendu, le nombre de modules intermédiaires peut être différent ; il est également possible que la structure ne comprenne pas de module intermédiaire, auquel cas cette structure télescopique 2 ne comprend que le module fixe 4 et le module extrémal 6 monté mobile en translation sur le module fixe 4, comme représenté sur les figures.In the embodiment shown in the figures 1 to 5 , the number of modules of the telescopic structure 2 is four. In addition to the fixed module 4, the plurality of modules comprises an extremal mobile module 6, a first intermediate module 8 in which the extremal mobile module 4 is able to retract, a second intermediate module 10 in which the first intermediate module 8 is able to retract, the second intermediate module 10 itself being able to retract into the fixed module 4. Of course, the number of intermediate modules can be different; it is also possible that the structure does not include an intermediate module, in which case this structure telescopic 2 comprises only the fixed module 4 and the extremal module 6 mounted movable in translation on the fixed module 4, as shown in the figures.

Le module mobile extrémal 6 comprend deux montants longitudinaux 12 et un toit 14 reliant les deux montants longitudinaux 12.The extremal mobile module 6 comprises two longitudinal uprights 12 and a roof 14 connecting the two longitudinal uprights 12.

Le toit 14 recouvre une partie du bassin de la piscine lorsque la structure est dans sa configuration fermée. Le toit 14 est sensiblement parallèle aux margelles de la piscine, et plus généralement au sol environnant la piscine.The roof 14 covers part of the pool basin when the structure is in its closed configuration. The roof 14 is substantially parallel to the copings of the swimming pool, and more generally to the ground surrounding the swimming pool.

Les deux montants longitudinaux 12 s'étendent parallèlement à l'axe de translation de la structure télescopique 2.The two longitudinal uprights 12 extend parallel to the axis of translation of the telescopic structure 2.

Un des montants longitudinaux 12 s'étend verticalement entre une première margelle de la piscine et le toit 14. L'autre montant longitudinal 12 s'étend verticalement entre une deuxième margelle de la piscine et le toit 14, la deuxième margelle étant opposée à la première margelle par rapport au bassin de la piscine.One of the longitudinal uprights 12 extends vertically between a first edge of the pool and the roof 14. The other longitudinal upright 12 extends vertically between a second edge of the pool and the roof 14, the second edge being opposite the first edge in relation to the pool basin.

Le module extrémal 6 peut également comprendre un montant transversal 16, qui relie mutuellement les deux montant longitudinaux 12. Le montant transversal 16 est également relié au toit 14. Le montant transversal 16 est destiné à se trouver au-dessus d'une troisième margelle reliant la première margelle à la deuxième margelle. Le montant transversal s'étend perpendiculairement aux deux montants longitudinaux.The extremal module 6 can also comprise a transverse upright 16, which mutually connects the two longitudinal uprights 12. The transverse upright 16 is also connected to the roof 14. The transverse upright 16 is intended to be above a third coping connecting the first curb to the second curb. The transverse upright extends perpendicularly to the two longitudinal uprights.

Les autres modules (le module fixe 4 et les modules intermédiaires, 8, 10) présentent les mêmes caractéristiques que le module extrémal 6, sauf que leurs dimensions sont différentes. En effet, la distance séparant les deux montants longitudinaux 12 de chaque module est propre à ce module. Les deux montants longitudinaux 12 du module mobile extrémal 6 sont situés entre les deux montants longitudinaux du premier module intermédiaire 8 ; les deux montants longitudinaux du premier module intermédiaire 8 sont situés entre les deux montants longitudinaux du deuxièmes module intermédiaire 10 ; et les deux montants longitudinaux du deuxième module intermédiaire 10 sont situés entre les deux montants longitudinaux du module fixe 4. En d'autres termes, le module fixe 4 est le module qui présente la plus grande largeur, mesurée dans une direction transversale perpendiculaire à ses montants longitudinaux, et la plus grande hauteur, mesurée perpendiculairement à un sol sur lequel est posé la structure 2. Cette hauteur et cette largeur décroissent de module en module, lorsque l'on parcourt la structure télescopique 2 du module fixe 4 jusqu'au module mobile extrémal 6.The other modules (the fixed module 4 and the intermediate modules, 8, 10) have the same characteristics as the extremal module 6, except that their dimensions are different. Indeed, the distance separating the two longitudinal uprights 12 of each module is specific to this module. The two longitudinal uprights 12 of the extremal mobile module 6 are located between the two longitudinal uprights of the first intermediate module 8; the two longitudinal uprights of the first intermediate module 8 are located between the two longitudinal uprights of the second intermediate module 10; and the two longitudinal uprights of the second intermediate module 10 are located between the two longitudinal uprights of the fixed module 4. In other words, the fixed module 4 is the module which has the greatest width, measured in a transverse direction perpendicular to its longitudinal uprights, and the greatest height, measured perpendicular to a floor on which the structure 2 is placed. This height and this width decrease from module to module, when the telescopic structure 2 is traversed from the fixed module 4 to the module extremal mobile 6.

Au moins un module mobile peut comprendre au moins une roue (non-illustrée) destinée à rouler sur la margelle ou sur un rail fixé à cette margelle, pour faciliter son déplacement en translation par rapport au module fixe 4.At least one mobile module may comprise at least one wheel (not shown) intended to roll on the coping or on a rail fixed to this coping, to facilitate its movement in translation relative to the fixed module 4.

Le dispositif 1 a pour fonction de rétracter la structure 2, c'est-à-dire la faire passer de sa configuration fermée vers sa configuration ouverte, dans le but de donner accès au bassin de la piscine, et vice-versa.The device 1 has the function of retracting the structure 2, that is to say moving it from its closed configuration to its open configuration, in order to provide access to the pool basin, and vice versa.

En référence aux figures 5 à 7 , le dispositif 1 comprend un élément de fixation 18 propre à être fixé à la structure télescopique 2, plus précisément au module mobile extrémal 6. Dans le mode de réalisation illustré sur ces figures, l'élément de fixation 18 est fixé au montant transversal 16 du module mobile extrémal. Cet élément de fixation 18 peut alternativement être fixé à un bord de l'un des montants longitudinaux 12 de ce module 6.With reference to figures 5 to 7 , the device 1 comprises a fixing element 18 adapted to be fixed to the telescopic structure 2, more precisely to the extremal mobile module 6. In the embodiment illustrated in these figures, the fixing element 18 is fixed to the transverse upright 16 of the extremal mobile modulus. This fixing element 18 can alternatively be fixed to an edge of one of the longitudinal uprights 12 of this module 6.

L'élément de fixation 18 comprend une base 20 et deux fourreaux 22, 24. La base 20 présente une surface plane propre à être plaquée contre le montant transversal 16 du module extrémal 6, et être maintenue dans cette position à l'aide de moyens appropriés, tels que des vis engagées dans des trous formés dans la base 20. La base 20 relie mutuellement les deux fourreaux 22, 24.The fixing element 18 comprises a base 20 and two sheaths 22, 24. The base 20 has a flat surface capable of being pressed against the transverse upright 16 of the end module 6, and to be held in this position using means suitable, such as screws engaged in holes formed in the base 20. The base 20 mutually connects the two sheaths 22, 24.

Les deux fourreaux 22, 24 à distance à l'un de l'autre de manière à définir entre eux un espace. Les deux fourreaux 22, 24 présentent deux orifices traversants coaxiaux 26, 28.The two sleeves 22, 24 at a distance from each other so as to define a space between them. The two sheaths 22, 24 have two coaxial through holes 26, 28.

Le dispositif 1 comprend par ailleurs une roue 30 montée à rotation sur l'élément de fixation 18 autour d'un axe de rotation Y. La roue 30 s'étend dans l'espace défini entre les deux fourreaux 22, 24.The device 1 also comprises a wheel 30 rotatably mounted on the fixing element 18 around an axis of rotation Y. The wheel 30 extends in the space defined between the two sheaths 22, 24.

L'axe de rotation Y de la roue 30 est perpendiculaire à l'axe X, donc à la direction de translation du module mobile extrémal 6 relativement au module fixe 4 (et relativement aux modules intermédiaires 8, 10, si présents).The axis of rotation Y of the wheel 30 is perpendicular to the axis X, therefore to the direction of translation of the extremal mobile module 6 relative to the fixed module 4 (and relative to the intermediate modules 8, 10, if present).

Une fois que l'élément de fixation 18 est fixé à la structure télescopique 2, la roue 30 repose sur une des margelles de la piscine. La roue 30 est orientée de sorte à rouler parallèlement à l'axe X, autrement dit dans la direction de translation des modules mobiles 6, 8, 10 de la structure télescopique 2 au cours de son ouverture.Once the fixing element 18 is fixed to the telescopic structure 2, the wheel 30 rests on one of the copings of the swimming pool. The wheel 30 is oriented so as to roll parallel to the axis X, in other words in the direction of translation of the mobile modules 6, 8, 10 of the telescopic structure 2 during its opening.

La roue 30 est montée à rotation sur les fourreaux 22, 24 grâce à un arbre 32, appelé arbre de sortie 32 dans la suite. Cet arbre de sortie 32 s'étend dans le long de l'axe de rotation Y.The wheel 30 is rotatably mounted on the sheaths 22, 24 by means of a shaft 32, called output shaft 32 below. This output shaft 32 extends along the axis of rotation Y.

La roue comprend un moyeu définissant un alésage à six pans, c'est-à-dire de profil hexagonal. L'arbre de sortie est engagé dans les deux orifices 26, 28 traversants coaxiaux ainsi que dans l'alésage à six pans. L'arbre de sortie 32 présente une section hexagonale complémentaire de l'alésage à six pans.The wheel comprises a hub defining a hexagonal bore, that is to say of hexagonal profile. The output shaft is engaged in the two coaxial through holes 26, 28 as well as in the hexagon bore. The output shaft 32 has a complementary hexagonal section of the hexagonal bore.

Le dispositif 1 comprend également un boîtier 34. Le boîtier 34 présente une forme allongée le long d'un axe longitudinal X1. La longueur du boîtier 34, par convention mesurée parallèlement à cet axe longitudinal X1, et supérieure à ses dimensions dans un plan normal à cet axe X1.The device 1 also comprises a casing 34. The casing 34 has an elongated shape along a longitudinal axis X1. The length of the housing 34, by convention measured parallel to this longitudinal axis X1, and greater than its dimensions in a plane normal to this axis X1.

La longueur du boîtier 34 est en revanche inférieure à la longueur du module mobile extrémal 6 mesurée parallèlement à l'axe X.The length of the housing 34 is on the other hand less than the length of the extremal mobile module 6 measured parallel to the axis X.

Le boîtier 34 s'étend le long de l'axe longitudinal X1 entre deux portions d'extrémité opposées : une première portion d'extrémité 36, et une deuxième portion d'extrémité 38.The housing 34 extends along the longitudinal axis X1 between two opposite end portions: a first end portion 36, and a second end portion 38.

Le boîtier 34 comprend quatre parois longitudinales 40, 42, 44, 46 s'étendant parallèlement à l'axe longitudinal X1, entre les deux portions d'extrémités 36, 38. Les quatre parois et les portions d'extrémité et définissant entre elles une cavité interne du boîtier 34.The housing 34 comprises four longitudinal walls 40, 42, 44, 46 extending parallel to the longitudinal axis X1, between the two end portions 36, 38. The four walls and the end portions and defining between them a internal cavity of the housing 34.

Les quatre parois longitudinales 40, 42, 44, 46 comprennent : deux parois latérales 40, 42 en regard l'une de l'autre, ainsi que des parois respectivement inférieure 44 et supérieure 46. La paroi inférieure 44 et la paroi supérieure 46 relient les parois latérales l'une à l'autre 40, 42. Les parois latérales sont perpendiculaires aux parois inférieure et supérieure, de manière à définir pour le boîtier 34 une section rectangulaire dans un plan normal à l'axe X1.The four longitudinal walls 40, 42, 44, 46 comprise: two side walls 40, 42 facing each other, as well as respectively lower 44 and upper 46 walls. The lower wall 44 and the upper wall 46 connect the side walls to each other 40, 42. The side walls are perpendicular to the lower and upper walls, so as to define for the box 34 a rectangular section in a plane normal to the axis X1.

La dimension du boîtier 34 mesurée perpendiculairement à l'axe X1 de la paroi inférieure à la paroi supérieure est inférieure au diamètre de la roue 30.The dimension of the housing 34 measured perpendicular to the axis X1 from the lower wall to the upper wall is less than the diameter of the wheel 30.

Le boîtier 34 comprend deux parties 34a, 34b formant deux coques destinées à être fixées l'une à l'autre à l'aide de vis ou de moyens équivalents pour fermer le boîtier 34. Ces deux parties 34a, 34b sont représentées à distance l'une de l'autre sur la figure 8.The housing 34 comprises two parts 34a, 34b forming two shells intended to be fixed to each other using screws or equivalent means to close the housing 34. These two parts 34a, 34b are shown at a distance l each other on the figure 8 .

La paroi latérale 40 définit un orifice de sortie entre la cavité interne du boîtier 34 et l'extérieur du boîtier 34. Par convention, on appelle cette paroi latérale 40 « paroi intérieure », et l'autre paroi latérale 42 « paroi extérieure » par opposition.The side wall 40 defines an outlet orifice between the internal cavity of the casing 34 and the exterior of the casing 34. By convention, this side wall 40 is called the "inner wall", and the other side wall 42 "outer wall" by opposition.

L'orifice de sortie est plus proche de la première portion d'extrémité 36 que de la deuxième portion d'extrémité 38.The outlet orifice is closer to the first end portion 36 than to the second end portion 38.

Le boîtier 34 est monté mobile en rotation sur l'élément de fixation 18 autour de l'axe Y (qui est, pour rappel, l'axe de rotation de la roue 30 relativement à l'élément de fixation 18). A cet effet, l'arbre de sortie 32 traverse l'orifice de sortie. Autrement dit, l'axe de rotation du boîtier 34 par rapport à l'élément de fixation 18 et l'axe de rotation de la roue par rapport à l'élément de fixation 18 sont non seulement parallèles, mais encore confondus. Ceci a pour avantage de réduire le nombre de pièces du dispositif 1, comparativement à un dispositif utilisant deux axes de rotation différents.The housing 34 is rotatably mounted on the fixing element 18 around the axis Y (which is, as a reminder, the axis of rotation of the wheel 30 relative to the fixing element 18). To this end, the output shaft 32 passes through the outlet orifice. In other words, the axis of rotation of the housing 34 with respect to the fixing element 18 and the axis of rotation of the wheel with respect to the fixing element 18 are not only parallel, but also coincident. This has the advantage of reducing the number of parts of the device 1, compared to a device using two different axes of rotation.

L'axe longitudinal X1 du boîtier 34 est perpendiculaire à l'axe Y.The longitudinal axis X1 of the housing 34 is perpendicular to the Y axis.

Le boîtier 34 présente une surface extérieure 50 s'étendant autour de l'axe de rotation Y. Cette surface 50 est définie par la paroi inférieure 44, la paroi supérieure 46 et par les deux portions d'extrémité 36, 38. Cette surface extérieure 50 a un profil oblong dans un plan normal à l'axe de rotation Y. On verra dans la suite que cette surface extérieure 50 peut prendre appui sur la structure télescopique 2 au cours de son ouverture, notamment au niveau de la deuxième portion d'extrémité 38 et de la paroi inférieure 44. Cette surface 50 comprend en particulier une portion de surface plane 52 inclinée par rapport à l'axe longitudinal X1. Cette surface plane 52 est définie par la deuxième portion d'extrémité 38 du boîtier 34.The housing 34 has an outer surface 50 extending around the axis of rotation Y. This surface 50 is defined by the lower wall 44, the upper wall 46 and by the two end portions 36, 38. This outer surface 50 has an oblong profile in a plane normal to the axis of rotation Y. It will be seen below that this outer surface 50 can rest on the telescopic structure 2 during its opening, in particular at the level of the second portion of end 38 and of the lower wall 44. This surface 50 comprises in particular a flat surface portion 52 inclined with respect to the longitudinal axis X1. This flat surface 52 is defined by the second end portion 38 of the casing 34.

Le dispositif 1 comprend par ailleurs un pion faisant saillie depuis la paroi intérieure 40 (définissant l'orifice de sortie). Ce pion n'est pas représenté sur les figures 5 à 7, mais est visible sur les figures 1 à 4. Le pion s'étend dans une direction parallèle à l'axe de rotation Y.The device 1 also comprises a pin projecting from the inner wall 40 (defining the outlet orifice). This pawn is not represented on the figures 5 to 7 , but is visible on figures 1 to 4 . The pawn extends in a direction parallel to the axis of rotation Y.

Lorsque l'élément de fixation 18 est fixé au module mobile extrémal 6 de la structure télescopique 2, alors que cette structure 2 est elle-même dans sa configuration fermée couvrant une piscine, le boîtier 34 peut être placé dans différentes positions par rapport à l'élément de fixation 18 (et, par extension, par rapport au module mobile extrémal 6), notamment dans une position verticale et une position inclinée.When the fixing element 18 is fixed to the extremal mobile module 6 of the telescopic structure 2, while this structure 2 is itself in its closed configuration covering a swimming pool, the box 34 can be placed in different positions with respect to the fixing element 18 (and, by extension, relative to the extremal mobile module 6), in particular in a vertical position and an inclined position.

Dans la position verticale, représentée en figure 7, l'axe longitudinal X1 est perpendiculaire à la direction de translation du module extrémal 6, donc perpendiculaire à l'axe X. La première portion d'extrémité se trouve entre le sol et la deuxième portion d'extrémité. Par ailleurs, la deuxième portion d'extrémité peut alors se trouver au-dessus du toit 14 du module extrémal 6.In the vertical position, shown in figure 7 , the longitudinal axis X1 is perpendicular to the direction of translation of the extremal module 6, therefore perpendicular to the axis X. The first end portion is located between the ground and the second end portion. Furthermore, the second end portion can then be above the roof 14 of the extremal module 6.

Dans la position inclinée, représentée sur les figures 1 à 4, l'axe longitudinal X1 forme un angle inférieur à 45 degrés par rapport à la direction de translation, donc par rapport à l'axe X. La deuxième portion d'extrémité du boîtier 34 est alors plus proche des autres modules que ne l'est la première portion d'extrémité. Par ailleurs, le pion repose sur le toit 14 du module mobile extrémal 6, de sorte à empêcher la deuxième portion d'extrémité de toucher le sol. Dans le mode de réalisation représenté sur les figures 1 à 4, cet angle est de l'ordre de 10 degrés. Le pion constitue une butée limitant la course de rotation du boîtier 34 par rapport à l'élément de fixation 18, une fois l'élément de fixation 18 fixé à la structure télescopique 2.In the reclined position, represented on the figures 1 to 4 , the longitudinal axis X1 forms an angle of less than 45 degrees with respect to the direction of translation, therefore with respect to the axis X. The second end portion of the housing 34 is then closer to the other modules than is the first end portion. Furthermore, the pin rests on the roof 14 of the extremal mobile module 6, so as to prevent the second end portion from touching the ground. In the embodiment shown in the figures 1 to 4 , this angle is of the order of 10 degrees. The pin constitutes a stop limiting the rotational travel of the housing 34 relative to the fixing element 18, once the fixing element 18 is fixed to the telescopic structure 2.

Dans la position inclinée, La surface plane 52 est simultanément en regard du sol et du premier module intermédiaire 8. Elle s'étend dans un plan incliné à moins de 90 degrés par rapport à l'axe longitudinal X (indiquant la direction de translation de la structure 2).In the inclined position, the flat surface 52 is simultaneously opposite the ground and the first intermediate module 8. It extends in an inclined plane at less than 90 degrees with respect to the longitudinal axis X (indicating the direction of translation of structure 2).

En référence aux figures 8 à 10 , le boîtier 34 contient un moteur 54 pour entraîner la roue en rotation par rapport à l'élément de fixation 18. Ainsi, lorsque l'élément de fixation 18 est fixé au module extrémal, et que la roue repose sur le sol, la roue peut rouler sur le sol sous l'effet du moteur et entraîner un déplacement en translation de l'élément de fixation 18 par rapport au sol parallèlement à l'axe X, et entraîner conséquemment le module extrémal en translation par rapport aux autres modules.With reference to figures 8 to 10 , the housing 34 contains a motor 54 to drive the wheel in rotation relative to the fixing element 18. Thus, when the fixing element 18 is fixed to the extremal module, and the wheel rests on the ground, the wheel can roll on the ground under the effect of the motor and cause a movement in translation of the fixing element 18 with respect to the ground parallel to the axis X, and consequently cause the extremal module in translation with respect to the other modules.

Le moteur 54 comprend en particulier un arbre moteur 56 s'étendant parallèlement à l'axe longitudinal X1 du boîtier 34. Le fait que le moteur 54 soit orienté de cette manière permet de limiter ses dimensions dans un plan transversal perpendiculaire à l'axe longitudinal X1, donc permet de conférer au boîtier 34 une forme fortement allongée, masquable plus facilement.The motor 54 comprises in particular a motor shaft 56 extending parallel to the longitudinal axis X1 of the housing 34. The fact that the motor 54 is oriented in this way makes it possible to limit its dimensions in a transverse plane perpendicular to the longitudinal axis X1, therefore makes it possible to give the case 34 a greatly elongated shape, which can be masked more easily.

L'arbre moteur 56 comprend une roue dentée conique 58.Motor shaft 56 includes a bevel gear 58.

Le boîtier 34 contient par ailleurs un réducteur 60 agencé pour transmettre un couple depuis le moteur 54 à la roue 30. Grâce au réducteur 60, la vitesse de rotation de la roue 30 par rapport à l'élément de fixation 18 est inférieure à la vitesse de rotation de l'arbre moteur 56 par rapport au boîtier 34.The housing 34 also contains a reduction gear 60 arranged to transmit a torque from the motor 54 to the wheel 30. Thanks to the reduction gear 60, the speed of rotation of the wheel 30 with respect to the fixing element 18 is lower than the speed rotation of motor shaft 56 relative to housing 34.

Le réducteur 60 comprend un train d'engrenages à axes parallèles. Les axes des engrenages sont parallèles à l'axe de rotation Y de la roue 30 par rapport à l'élément de fixation 18.The reducer 60 comprises a gear train with parallel axes. The axes of the gears are parallel to the axis of rotation Y of the wheel 30 with respect to the fixing element 18.

Dans le mode de réalisation illustré sur les figures 8 et 9, le train d'engrenages comprend neuf roues dentées réparties sur cinq axes parallèles à l'axe Y, mais ce nombre de roues dentées ou d'axes peut être différent.In the embodiment illustrated in the figure 8 and 9 , the gear train includes nine cogwheels distributed over five axes parallel to the Y axis, but this number of cogwheels or axes can be different.

Le train d'engrenages comprend notamment une roue dentée d'entrée 62 qui engrène avec la roue dentée conique 58 de l'arbre moteur, de manière à former à un renvoi d'angle. Autrement dit, l'axe de rotation de la roue dentée d'entrée 62 et l'axe de rotation de l'arbre moteur 56 sont perpendiculaires. Ceci contribue à conférer au boîtier 34 une forme fortement allongée, masquable plus facilement.The gear train includes in particular an input toothed wheel 62 which meshes with the conical toothed wheel 58 of the motor shaft, so as to form a bevel gear. In other words, the axis of rotation of the input toothed wheel 62 and the axis of rotation of the motor shaft 56 are perpendicular. This contributes to giving the box 34 a greatly elongated shape, which can be masked more easily.

Le train d'engrenages comprend par ailleurs une roue dentée de sortie 64 fixée à l'arbre de sortie 32 de manière à entraîner cet arbre de sortie 32 en rotation par rapport au boîtier 34 (et donc la roue par rapport à l'élément de fixation 18). A cet effet, la roue dentée de sortie 64 peut comprendre un alésage à six pans du même type que celui de la roue 30.The gear train also comprises an output toothed wheel 64 fixed to the output shaft 32 so as to drive this output shaft 32 in rotation relative to the housing 34 (and therefore the wheel relative to the attachment 18). For this purpose, the output toothed wheel 64 may comprise a hexagonal bore of the same type as that of the wheel 30.

L'ouverture de la structure télescopique 2, c'est-à-dire son passage de sa configuration fermée à sa configuration ouverte peut être réalisée automatiquement une fois le dispositif 1 fixé au module mobile extrémal 6. Cette ouverture peut être réalisée de la manière suivante.The opening of the telescopic structure 2, that is to say its passage from its closed configuration to its open configuration, can be carried out automatically once the device 1 has been fixed to the extremal mobile module 6. This opening can be carried out in the manner next.

On suppose que dans un premier temps la structure télescopique 2 est dans sa configuration fermée. Les modules sont ainsi déployés les uns à côté des autres au-dessus d'une piscine.It is assumed that initially the telescopic structure 2 is in its closed configuration. The modules are thus deployed next to each other above a swimming pool.

Pour éviter que le dispositif 1 ne soit trop visible, le boîtier 34 est placé dans sa position inclinée. Pour cela, un utilisateur peut tourner manuellement le boîtier 34 relativement à l'élément de fixation 18, le moteur 54 étant éteint.To prevent the device 1 from being too visible, the box 34 is placed in its inclined position. For this, a user can manually turn the housing 34 relative to the fixing element 18, the motor 54 being off.

A ce stade, le boîtier 34 se trouve à distance du premier module intermédiaire 8.At this stage, the box 34 is at a distance from the first intermediate module 8.

Le moteur 54 est ensuite mis en route par des moyens appropriés (par exemple un bouton prévu à cet effet sur le boîtier 34). L'arbre moteur 56 est alors mis en rotation relativement au boîtier 34. Par l'intermédiaire du réducteur 60, la rotation de l'arbre moteur 56 entraine une rotation de l'arbre de sortie 32 relativement au boîtier 34 et à l'élément de fixation 18. La roue 30 se déplace alors sur le sol sur lequel elle repose, et entraîne un déplacement en translation de l'élément de fixation 18 et du module extrémal 6 suivant l'axe X, vers le module fixe 4 de la structure télescopique 2. Le module extrémal 6 commence alors à se rétracter dans le premier module intermédiaire 8.The motor 54 is then started by appropriate means (for example a button provided for this purpose on the housing 34). The motor shaft 56 is then rotated relative to the housing 34. Via the reducer 60, the rotation of the motor shaft 56 causes a rotation of the output shaft 32 relative to the housing 34 and to the element fixing 18. The wheel 30 then moves on the ground on which it rests, and causes a movement in translation of the fixing element 18 and of the extremal module 6 along the axis X, towards the fixed module 4 of the structure telescopic 2. The extremal module 6 then begins to retract into the first intermediate module 8.

Au cours du déplacement du module extrémal 6, le boîtier 34 est susceptible de rester dans sa position inclinée. A un certain stade représenté sur les figures 3 et 4, la surface extérieure du boîtier 34 vient en appui sur le premier module intermédiaire 8 (plus précisément, sur le bord d'un des montants longitudinaux de ce premier module intermédiaire 8). Toutefois, le module extrémal 6 continue ensuite à se rétracter à l'intérieur du premier module intermédiaire ; en conséquence, l'axe de rotation Y continue de se rapprocher du premier module intermédiaire. Le premier module intermédiaire contraint alors le boîtier 34 à pivoter vers la position verticale. Au cours de ce pivotement, la surface extérieure 50 du boîtier 34 glisse contre le premier module intermédiaire 8. Il est à noter que le caractère incliné de la surface plane d'appui 52 du boîtier 34 a pour effet de faciliter ce pivotement. Il est à noter que la mise en rotation de l'arbre de sortie 32 relativement au boîtier 34 est susceptible d'entraîner un pivotement résiduel du boîtier 34 vers le bas en cas de frictions. Ce pivotement résiduel est toutefois bloqué par le pion faisant saillie hors du boîtier 34 et reposant sur le toit 14. De manière générale, le pion formant butée permet d'éviter que le boîtier 34 ne racle sur le sol pendant l'ouverture de la structure télescopique 2. Il permet aussi de maintenir le boîtier dans une position inclinée lui permettant de glisser contre le premier module intermédiaire 8.During the displacement of the extremal module 6, the casing 34 is likely to remain in its inclined position. At a certain stage represented on the figures 3 and 4 , the outer surface of the housing 34 comes to rest on the first intermediate module 8 (more precisely, on the edge of one of the longitudinal uprights of this first intermediate module 8). However, the extremal module 6 then continues to retract inside the first intermediate module; consequently, the axis of rotation Y continues to approach the first intermediate module. The first intermediate module then forces the housing 34 to pivot towards the vertical position. During this pivoting, the outer surface 50 of the casing 34 slides against the first intermediate module 8. It should be noted that the inclined nature of the flat bearing surface 52 of the casing 34 has the effect of facilitating this pivoting. It should be noted that the rotation of the output shaft 32 relative to the housing 34 is likely to cause a residual pivoting of the housing 34 downwards in the event of friction. This residual pivoting is however blocked by the pin protruding from the casing 34 and resting on the roof 14. In general, the pin forming a stop makes it possible to prevent the casing 34 from scraping on the ground during the opening of the structure. telescopic 2. It also keeps the box in an inclined position allowing it to slide against the first intermediate module 8.

Une fois que le module extrémal 6 a terminé sa course de rétractation à l'intérieur du premier module intermédiaire 8, le module extrémal 6 entraîne un déplacement en translation du premier module intermédiaire 8 par rapport au deuxième module intermédiaire 10. Le deuxième module intermédiaire 10 est par la suite également entraîné en translation par rapport au module fixe 4, jusqu'à ce que la structure 2 atteigne sa configuration ouverte, représentée notamment en figures 3, 4 et 5.Once the extremal module 6 has completed its retraction stroke inside the first intermediate module 8, the extremal module 6 causes a displacement in translation of the first intermediate module 8 relative to the second intermediate module 10. The second intermediate module 10 is subsequently also driven in translation with respect to the fixed module 4, until the structure 2 reaches its open configuration, represented in particular in figures 3, 4 and 5 .

Bien que le boîtier 34 a la possibilité d'être positionné manuellement dans la position verticale, le boîtier peut être agencé de manière à atteindre, sous l'effet du premier module intermédiaire 8, dans une position relevée qui n'est pas tout à fait verticale, mais proche de celle-ci. Par exemple, dans le mode de réalisation illustré en figure 5, le boîtier 34 est relevé par la structure télescopique 2 dans une position relevée dans laquelle l'axe longitudinal X1 forme un angle compris entre 90 et 80 degrés par rapport à la direction de translation de la structure 2, indiquée par l'axe X.Although the box 34 has the possibility of being positioned manually in the vertical position, the box can be arranged so as to reach, under the effect of the first intermediate module 8, in a raised position which is not quite vertical, but close to it. For example, in the embodiment illustrated in figure 5 , the housing 34 is raised by the telescopic structure 2 in a raised position in which the longitudinal axis X1 forms an angle of between 90 and 80 degrees with respect to the direction of translation of the structure 2, indicated by the axis X.

En définitive, un utilisateur n'a pas besoin de pivoter manuellement le boîtier 34 dans le but d'éviter que ce boîtier 34 ne limite de façon substantielle la course de rétractation du module extrémal 6 dans le premier module intermédiaire 8. Ce pivotement se produit en effet naturellement au cours de l'ouverture de la structure télescopique 2. Il n'est pas non plus nécessaire de prévoir un moteur dédié pour assurer ce pivotement, puisque ce pivotement est provoqué par le roulage du dispositif 1 sur le sol, ce roulage étant lui-même causé par l'action du moteur 54 déjà présent dans le dispositif 1.Ultimately, a user does not need to manually pivot the casing 34 in order to prevent this casing 34 from substantially limiting the retraction travel of the extremal module 6 in the first intermediate module 8. This pivoting occurs indeed naturally during the opening of the telescopic structure 2. It is also not necessary to provide a dedicated motor to ensure this pivoting, since this pivoting is caused by the rolling of the device 1 on the ground, this rolling being itself caused by the action of the motor 54 already present in the device 1.

Il est par ailleurs encore possible de faire pivoter manuellement le boîtier 34 par rapport à l'élément de fixation 18 dans une position couchée, dans laquelle la première portion d'extrémité 36 se trouve entre la deuxième portion d'extrémité 38 et le premier module intermédiaire (pivotement vers la gauche si l'on se réfère à la figure 5).It is furthermore still possible to manually pivot the casing 34 with respect to the fixing element 18 in a lying position, in which the first end portion 36 is located between the second end portion 38 and the first module. intermediate (pivoting to the left if we refer to the figure 5 ).

Pour fermer la structure télescopique 2, le moteur est mis en route de telle sorte que l'arbre moteur 32 tourne par rapport au boîtier 34 dans un sens de rotation opposé à celui utilisé pour l'ouverture de la structure télescopique 2. En conséquence, la roue 30 roule sur le sol dans un sens qui entraîne un éloignement du module extrémal 6 du reste de la structure télescopique 2. Une fois la structure télescopique 2 complètement fermée, un utilisateur peut pivoter manuellement le boîtier 34 dans sa position inclinée, dans laquelle le pion est en butée sur le toit 14, à moins bien sûr que le boîtier n'ait pas naturellement déjà atteint cette position au cours de la fermeture de la structure télescopique 2.To close the telescopic structure 2, the motor is started so that the motor shaft 32 rotates relative to the housing 34 in a direction of rotation opposite to that used for the opening of the telescopic structure 2. Consequently, wheel 30 rolls on the ground in a direction which causes the extremal module 6 to move away from the rest of the telescopic structure 2. Once the telescopic structure 2 is completely closed, a user can manually pivot the casing 34 into its inclined position, in which the pin is in abutment on the roof 14, unless of course the box has not naturally already reached this position during the closing of the telescopic structure 2.

D'autres modes de réalisation que ceux représentés sur les figures peuvent être envisagés. En particulier :

  • Dans ce qui précède, il a été considéré le cas où le boîtier 34 pivote par sollicitation du module immédiatement voisin du module extrémal, à savoir le premier module intermédiaire. En variante, ce pivotement peut être causé par un autre module de la structure télescopique 2
  • Il a été considéré ci-dessus l'exemple d'une structure télescopique 2 formant un abri de piscine. Le dispositif 1 peut toutefois trouver application pour déplacer d'autres types de structures télescopiques.
  • Bien qu'avantageuses, les aptitudes du boîtier à atteindre une position verticale et une position inclinée à 45 degrés par rapport à la direction de translation restent facultatives. Le boîtier pourrait en effet être mobile en rotation sur une angulation inférieure à 45 degrés.
Other embodiments than those shown in the figures can be considered. Specifically :
  • In the foregoing, the case was considered where the casing 34 pivots by stressing the module immediately adjacent to the extremal module, namely the first intermediate module. Alternatively, this pivoting can be caused by another module of the telescopic structure 2
  • It was considered above the example of a telescopic structure 2 forming a swimming pool enclosure. The device 1 can however find application for moving other types of telescopic structures.
  • Although advantageous, the abilities of the box to reach a vertical position and a position inclined at 45 degrees relative to the direction of translation remain optional. The casing could in fact be rotatable over an angulation of less than 45 degrees.
