Abstract

The cover has a tarpaulin that freely and completely rests on entire water surface (2), where an edge (5) of the tarpaulin follows and links with an inner edge (4) of a swimming pool. The tarpaulin is made of an open looped fabric, which is constituted of a material e.g. polypropylene, of density lower than that of water, where the tarpaulin edge has a seam (10) and a rectilinear bead (13), which is made of an expanded alveolar material or elastic material.

Description

L'invention a pour objet une couverture de piscine, pour l'hiver parThe subject of the invention is a swimming pool cover, for the winter by

exemple ART ANTERIEUR On connaît l'art et la manière de recouvrir d'une bâche les piscines en plein air pendant la mauvaise saison, pour protéger l'eau que l'on tient généralement à conserver, à l'encontre des chutes de feuilles, de débris divers transportés par le vent, aussi bien que pour la protéger le la lumière solaire engendrant le développement des algues et autre;; micro-organismes.  EXAMPLE PRIOR ART The art and the manner of covering outdoor swimming pools with a tarpaulin during the bad season are known, in order to protect the water which is generally held to preserve, against the falling of leaves, various debris transported by wind, as well as to protect it from sunlight generating the development of algae and other; microorganisms.

La bâche est avantageusement constituée d'un tissu ou toile en monofilaments de polypropylène de couleur sombre (vert, noir), ce tissu a une densité inférieure à celle de l'eau ce qui lui permet de flotter ce tissu est assez ouvert de façon à laisser passer l'eau de pluie et la neige fondue; ce tissu puisque constitué de monofilaments ou crins est assez rigide.  The tarpaulin is advantageously made of a fabric or canvas made of polypropylene monofilaments of a dark color (green, black), this fabric has a density lower than that of water, which allows it to float, this fabric is quite open so as to let rain and melted snow pass; this fabric since made of monofilaments or horsehair is quite rigid.

La bâche est tendue au-dessus de la piscine au moyen de tendeurs, par-dessus la margelle. Un inconvénient de telles couvertures est de se prêter assez mal à la protection des piscines en surélévatio a, car on est contraint de replier la bâche par-dessus la paroi. En outre par vent fort, celui-ci peut s'engouffrer au-dessous de la bâche puisqu'elle se trouve en surplomb de part et d'autre de la margelle ou des bords supérieurs de la paroi L'INVENTION Pour pallier aux inconvénients sus visés, l'idée mère de l'invention consiste à ne laisser la bâche en contact qu'avec la seule sur-face de l'eau mais de préférence avec toute la surface. Ce but est atteint par un plan de la bâche identique au plan de la surface de l'eau de la piscine; cette identité peut être obtenue, lorsque le contour de la surface de l'eau n'est pas régulier (rectangulaire ou rigoureusement circulaire), en tendant la toile au dessus de la surface de la piscine et en traçant, par une sorte de décalquage, le contour in-terne de la margelle; mais on peut encore tracer le contour à partir d'un plan exact. Dores et déjà on peut constater que la bâche en raison de la faible densité du tissu flotte à la surface de l'eau, et que en raison de 2907823 2 sa relative rigidité elle conserve son extension sur toute la surface; cependant on peut craindre que par grand vent celui ci ne la repousse et ne la tasse cDntre un bord en aval par rapport à sa direction; c'est pourquoi il est préférable d'apporter à la bâche les aménagements qui suivent.  The tarpaulin is stretched over the pool by means of turnbuckles, over the coping. A disadvantage of such covers is to lend themselves badly to the protection of the pools in a raised because it is forced to fold the cover over the wall. In addition, in strong winds, it may rush below the sheet since it is overhanging on either side of the rim or the upper edges of the wall The invention to overcome the drawbacks above targeted, the main idea of the invention is to leave the tarpaulin in contact with the only surface of the water but preferably with the entire surface. This goal is achieved by a plan of the tarpaulin identical to the plane of the water surface of the pool; this identity can be obtained when the contour of the surface of the water is not regular (rectangular or rigorously circular), by stretching the fabric over the surface of the pool and tracing, by a sort of trimming, the in-dull contour of the coping; but you can still draw the outline from an exact plane. Already it can be seen that the tarpaulin because of the low density of the fabric floats on the surface of the water, and that due to its relative stiffness it retains its extension over the entire surface; However, it is to be feared that, in strong wind, the latter may push it away, and not cup it, an edge downstream of its direction; that is why it is better to bring to the tarpaulin the following arrangements.

5 D'un part on va exécuter à partir du ;racé du contour sus visé, un second tracé extérieur au premier et distant de lui (le cinq à dix centimètres, de façon à permettre la confection d'un ourlet, sans pour cela réduire la surface de la bâche; la présence de l'ourlet confère par elle-même une certaine rigidité au pourtour de la bâche.On the one hand we will execute from the racé of the contour referred to above, a second trace outside the first and distant from him (the five to ten centimeters, so as to allow the making of a hem, without reducing it. the surface of the sheet, the presence of the hem confers by itself a certain rigidity around the perimeter of the tarpaulin.

10 Cependant l'ourlet peut aussi servir à loger un organe de rigidification dit rigidificateur, du pourtour de la bâche,. L'organe de rigidification est avantageusement un boudin rectiligne de matière élastique de quelques vingt à trente millimètres de diamètre, mais suffisamment souple pour pouvoir suivre, c'est-à-dire êtce incur- 15 vé, le pourtour de la bâche Il résulte de cette disposition que l'organe élastique ayant tendance à retrouver sa rectitude, contraindra la bâche à prendre son expansion maximale Avantageusement encore l'organe de rigidification 20 a aussi une fonction de flotteur; pour cela la matière élastique sus visée sera d'une densité très inférieure à celle de l'eau (par exemple d = 0,5), ce pourra être une matière alvéolaire à cellules fermées telle qu'un polyéthylène alvéolaire (tel que constitutif de certains bouchons replaçant le liège). Avantageusement encore, le bord de la bâche 25 contenant le flotteur dans l'ourlet, est aussi lesté da façon telle qu'il subsiste une flottabilité résiduelle. Le lest peut être une pluralité de poids répartis et suspendus le long de l'ourlet; ce peut-être encore, et avantageusement un lestage continu tel, par exemple, qu'une enfilade de perles de plombs, ou encore une petite chaîne d'acier inoxydable, ce lestage continu pouvant être lui aussi logé dans 30 l'ourlet en même temps que le boudin de matière élastique expansée. Il résulte de cette disposition que le bord le la bâche est alourdi tout en restant flottant, et qu'il n'est pas soulevé par le ve nt 2907823 3 Une bâche formant couverture de piscine comporte ainsi les caractéristiques, prises séparément ou en combinaison, répondant aux définitions suivantes : pour reposer librement et entièrement sur la tota-5 lité de la surface de l'eau, le bord de la bâche suit et épouse le bord intérieur de la piscine; le tissu est un tissu à maille ouvertes constitué d'une matière de densité inférieure à celle de l'eau; le bord de la bâche comporte et est constitué par 10 un ourlet, pylène, organe à fonction de flotteur, 15 le bord de la bâche comporte sur son pourtour un organe à fonction de rigidificateur, l'organe à fonction de flotteur est un boudin de matière alvéolaire expansée, l'organe à fonction de rigidificateur est un boudin 20 rectiligne de matière élastique, l'organe à fonction de flotteur est en même temps l'organe rigidificateur, cet organe étant un boudin rectiligne de matiè:.e alvéolaire expansée et élastique logée dans le dit ourlet, le bord de la bâche comporte en outre un lest, dit lest est un lestage continu lui aussi logé dans l'ourlet en même temps que le boudin de matière élastique expansée. Ces définitions seront mieux comprises à :.'examen des dessins de la figure annexée en relation avec les références qui suivent Sur la fig.l les références suivantes désignent: 1: la piscine, dans le cas présent est une piscine à plan elliptique la matière constitutive de la bâche est le polypro-le bord de la bâche comporte sur son pourtour un 25 30 2907823 4 2 : la surface de l'eau, qui est pratiquement recou-verte, 3 : la margelle de la piscine, 4 : la paroi ou bord intérieur de la piscine, dont 5 n'émerge au dessus de l'eau que la partie supérieure, 5 : le bord de la bâche, 6 : la bâche formant couverture de la piscine, Sur la figure 2, on retrouve certaine des références 10 précédentes désignant les mêmes éléments que ci-dessus; en outre les références suivantes désignent 10 : un ourlet sur le pourtour de la bâche, 11 : des lignes de couture ou de piqure de l'ourlet, 15 : la surface de l'eau normalement recouverte, Sur la figure 2, on retrouve certaines des références précédentes désignant le même élément que ci-dessus; en outre les références suivantes désignent : 13 : un flotteur en boudin de matière élastique al-20 véolaire de faible densité, 14 : un lest représenté schématiquement. Le lest et le flotteur sont visiblement contenus dans l'ourlet; sur les figu: es l'ourlet est montré, pour plus de visibilité, avec sa partie rabattue au-dessus; de façon 25 plus esthétique elle pourrait aussi bien être rabattue par-dessous. On nctera que les organes tels que flotteur-rigidificateur et le lest pourraient aussi bien fixés par soudage ou collage, ou encore être logés dans un ourlet rapporté par soudage ou collage. 15However, the hem may also be used to house a stiffening member said stiffener, around the perimeter of the tarpaulin. The stiffening member is advantageously a rectilinear bead of elastic material some twenty to thirty millimeters in diameter, but sufficiently flexible to be able to follow, that is to say, be curved, the perimeter of the tarpaulin. this arrangement that the elastic member having a tendency to regain its straightness, will force the sheet to take its maximum expansion Advantageously still the stiffening member 20 also has a float function; for this the elastic material referred to above will be of a density much lower than that of water (for example d = 0.5), it may be a cellular material with closed cells such as a cellular polyethylene (as constituting some plugs replacing the cork). Advantageously, the edge of the sheet 25 containing the float in the hem, is also ballasted so that residual buoyancy remains. The ballast may be a plurality of weights distributed and suspended along the hem; this may still be, and advantageously a continuous ballasting such, for example, a row of lead beads, or a small stainless steel chain, this continuous ballast can also be housed in the hem at the same time that the coil of elastic material expanded. It follows from this provision that the edge of the sheet is weighed while remaining floating, and that it is not lifted by the eye 2907823 3 A pool cover tarpaulin thus has the characteristics, taken separately or in combination, having the following definitions: to rest freely and entirely on the entire surface of the water, the edge of the sheet follows and marries the inner edge of the pool; the fabric is an open mesh fabric made of a material of lower density than water; the edge of the sheet comprises and consists of a hem, pylene, float function member, the edge of the sheet has on its periphery a stiffener function member, the float function member is a flange of expanded foam material, the stiffener function member is a rectilinear strand of elastic material, the float function member is at the same time the stiffening member, this member being a rectilinear flange of foamed foam material and resilient housed in said hem, the edge of the tarpaulin further comprises a ballast, said ballast is a continuous ballast also housed in the hem together with the bead of expanded elastic material. These definitions will be better understood on examining the drawings of the appended figure in conjunction with the following references. In FIG. 1, the following references denote: 1: the swimming pool, in this case is an elliptical pool the material The covering of the tarpaulin is polypro-the edge of the tarpaulin has on its periphery a surface of water, which is practically covered with green, 3: the edge of the pool, 4: the wall or inside edge of the pool, 5 of which emerges above the water only the upper part, 5: the edge of the cover, 6: the cover forming the pool cover, In Figure 2, there are some of previous references designating the same elements as above; in addition, the following references denote 10: a hem around the perimeter of the cover, 11: sewing or stitching lines of the hem, 15: the surface of the water normally covered, in FIG. previous references designating the same element as above; in addition, the following references denote: 13: a flotation float of alveolar material of low density, 14: a weight represented diagrammatically. The ballast and the float are visibly contained in the hem; on the figu: es the hem is shown, for more visibility, with its folded part above; in a more aesthetic way it could as well be folded underneath. It will be found that the organs such as float-stiffener and ballast could be fixed by welding or gluing, or be housed in a hem attached by welding or gluing. 15
