Abstract
Description
La présente invention vise les installations de couverture de piscines comprenant à une extrémité de la piscine un puits dans lequel s'étend un arbre horizontal sur lequel s'enroule un tapis, le puits et la piscine étant en communication par une fente horizontale pour le passage du tapis, l'arbre étant entraîné par un moteur, sélectivement dans un sens et dans l'autre et, le tapis étant formé de lames de matière plastique creuses qui flottent à la surface de l'eau et permettent, d'une part, de maintenir l'eau à sa température pendant les heures froides et, d'autre part, de chauffer ladite eau durant les heures ensoleillées par effet de serre. The present invention relates to swimming pool cover installations comprising at one end of the swimming pool a well in which extends a horizontal shaft on which a carpet is rolled up, the well and the swimming pool being in communication by a horizontal slot for the passage of the carpet, the shaft being driven by a motor, selectively in one direction and in the other and, the carpet being formed of hollow plastic blades which float on the surface of the water and allow, on the one hand, to maintain the water at its temperature during cold hours and, on the other hand, to heat said water during sunny hours by greenhouse effect.
Comme le tapis enroulé présente une certaine épaisseur, on est obligé de prévoir un arbre ayant un diamètre important. As the rolled-up carpet has a certain thickness, it is necessary to provide a tree having a large diameter.
On a constaté que lorsque le tapis était enroulé quelque soit le matériau employé pour réaliser l'arbre, du fait de la poussée verticale exercée par le tapis qui tend à remonter la surface, l'arbre prenait une flèche importante ce qui, bien entendu, gênait considérablement le fonctionnement. It was found that when the carpet was rolled up whatever the material used to make the tree, due to the vertical thrust exerted by the carpet which tends to go up the surface, the tree took a significant arrow which, of course, greatly hampered operation.
La présente invention a pour but notamment de remédier à cet inconvénient. The object of the present invention is in particular to remedy this drawback.
Les perfectionnements, selon l'invention, s'appliquent à des installations de couverture de piscines du type comprenant un puits disposé à l'une des extrémités de la piscine, un arbre tourillonné horizontalement dans le puits, des moyens pour entraîner, sélectivement, en rotation l'arbre dans un sens et dans l'autre, un tapis constitué de lames creuses de matière plastique, monté sur l'arbre et traversant une fente de mise en communication du puits et de la piscine pour flotter sur l'eau de celleci et la recouvrir, ledit arbre étant formé d'un élément tubulaire solidaire à chacune de ses extrémités d'un embout supportant un axe lesdits perfectionnements étant caractérisés en ce que dans l'élément tubulaire est logé un profilé affectant en section la forme d'une croix de Saint André et dont les extrémités des ailes portent contre la surface interne dudit élément tubulaire. The improvements according to the invention apply to swimming pool cover installations of the type comprising a well disposed at one end of the pool, a shaft journalled horizontally in the well, means for selectively driving in rotation of the tree in one direction and in the other, a carpet made up of hollow plastic blades, mounted on the tree and crossing a communication slot of the well and the pool to float on the water of this and cover it, said shaft being formed of a tubular element integral at each of its ends with a nozzle supporting an axis, said improvements being characterized in that in the tubular element is housed a profile which affects in section the shape of a cross of Saint Andrew and the ends of the wings of which bear against the internal surface of said tubular element.
L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels
Figure 1 est une vue en coupe schématique montrant une piscine pourvue d'une installation de couverture,
Figure 2 est une vue à plus grande échelle en élévation partiellement en coupe de l'arbre sur lequel s'enroule la couverture,
Figure 3 est une vue en coupe suivant la ligne
III-III de la figure 2.The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which
FIG. 1 is a schematic sectional view showing a swimming pool provided with a cover installation,
FIG. 2 is an enlarged view in partially sectioned elevation of the tree on which the cover is wound,
Figure 3 is a sectional view along the line
III-III of figure 2.
A la figure 1, on a représenté schématiquement en coupe une piscine 1 qui comporte à une extrémité un puits 2 dans lequel s'étend un arbre 3, celui-ci étant guidé dans des paliers horizontaux et relié à des moyens moteurs (non représentés) afin de le faire tourner sélectivement dans un sens et dans l'autre. In Figure 1, there is shown schematically in section a swimming pool 1 which has at one end a well 2 in which extends a shaft 3, the latter being guided in horizontal bearings and connected to motor means (not shown) in order to rotate it selectively in one direction and in the other.
Sur l'arbre 3 est enroulé un tapis 4 formé de lames creuses de matière plastique imbriquées les unes dans les autres, le tapis traversant une ouverture 5 pratiquée dans une paroi 11 séparant la piscine 1 du puits 2. On the shaft 3 is wound a carpet 4 formed of hollow plastic blades nested one inside the other, the carpet passing through an opening 5 made in a wall 11 separating the swimming pool 1 from the well 2.
L'arbre 3 (voir figures 2 et 3) est formé d'un élément tubulaire 6, en aluminium par exemple, à chaque extrémité duquel sont fixés des embouts 7 supportant des axes 8 destinés à être guidés dans des paliers et dont l'un est destiné à être relié au moteur par une liaison cinématique convenable. The shaft 3 (see Figures 2 and 3) is formed of a tubular element 6, of aluminum for example, at each end of which are fixed end pieces 7 supporting axes 8 intended to be guided in bearings and one of which is intended to be connected to the engine by a suitable kinematic link.
A l'intérieur de l'élément tubulaire 6 est logé un profilé 10 à section en croix de Saint André. Inside the tubular element 6 is housed a section 10 with a cross section of Saint Andrew.
Grâce à ce profilé 10 qui est simplement engagé dans l'élément tubulaire 6, on donne à l'arbre 3 une rigidité telle, qu'il ne fléchit pas vers la surface de l'eau malgré la poussée du tapis 4 qui étant constitué d'éléments flottants tend par conséquent à amener l'arbre vers la surface de l'eau. Thanks to this profile 10 which is simply engaged in the tubular element 6, the shaft 3 is given a rigidity such that it does not bend towards the surface of the water despite the thrust of the mat 4 which being made up of floating elements therefore tend to bring the tree towards the surface of the water.
Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représente. Of course, the invention is not limited to the embodiment which has just been described and represents.
On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention. Many modifications of detail can be made without departing from the scope of the invention.
