Definitions
- the invention relates to a rollable covering device. intended in particular to cover a basin such as a swimming pool, comprising, on the one hand, a flexible covering sheet with dimensions adapted to those of the basin to be covered and suitable for be wrapped around a winding bar of which it is secured to one of its transverse edges and, on the other hand, reinforcement bars arranged transversely and to which is made integral said sheet of recovery, as defined in claim 1.
- the present invention will find its application in the field covers for pools, especially swimming pools.
- a roll-up covering device for containers in particular for swimming pools, comprising a sheet of cover above which are designed, transversely, sheaths capable of accommodating bars reinforcement in the form of circular section tubes. All particularly, one of the transverse borders of this cover sheet receives, inside a sheath, a transverse reinforcement bar, at least one of the ends appear protruding laterally from the longitudinal edge of said cover sheet.
- This projecting end of said reinforcing bar comprises, in in addition, a maneuvering square on which a drive mechanism, such as a bevel gear allowing driving in rotation of said bar in view of the winding of the covering device via a crank.
- This drive mechanism can still be motorized.
- the gorges able to accommodate the transverse rods fitted to the tarpaulin elements are located on both sides and substantially in the horizontal median plane of the profiles constituting said reinforcing bars. Also, at the level of support zones at the edge of the basin, persists between these and the cover sheet a space allowing the passage of waste and others. In addition, these grooved profiles Again, create obstacles transverse to the winding direction of the covering device, obstacles that are particularly difficult to overcome, especially when this result must be obtained by dint of wrist through a crank.
- the present invention proposes to remedy all of the aforementioned drawbacks.
- the invention as defined in claims, solves the problem and consists of a device rollable covering intended in particular to cover a basin, such as a swimming pool, comprising, on the one hand, a sheet flexible cover with dimensions adapted to those of basin to be covered and suitable for being wrapped around a bar winding of which it is integral up to one of its transverse edges and, on the other hand, reinforcement bars arranged transversely and to which is made integral said cover sheet, said reinforcing bars being formed by section profiles approximately triangular comprising, on the one hand, a base by through which these sections are intended for rest on the edge of the basin to be covered and, on the other hand, at least one side, oriented towards said bar when the covering device is deployed, forming an acute angle of less than 70 ° with the base.
- the reinforcement bars are engaged in fitted sleeves transversely on the upper face of the sheet recovery.
- the profile constituting a bar reinforcement is a grooved profile having a groove extending, substantially, along the longitudinal edges of said base of the profile, said grooves being able to receive a rod fitted to each of the transverse edges of sections of cover sheets extending between two successive reinforcement bars.
- the advantages resulting from the present invention consist, basically, in that due to the configuration particular of the transverse reinforcement bars, these do not create, as before, more obstacles than appropriate just to cross. Indeed, the roller that constitutes the length of the already wound cover sheet comes, in this case, in contact with the inclined side of a bar reinforcement and, continuing the winding movement, this roller instead of passing, just above said bar reinforcement, causes the latter to tilt in the winding direction so that it offers only a lesser resistance to the current progression.
- the present invention is relating to a covering device 1 plus particularly intended for pools 2 of the swimming pool type or similar.
- the form of this basin can be arbitrary and that the device for recovery 1 is by no means limited to the form more particularly shown in the figure 1.
- this covering device 1 comprises a sheet of covering 3 of flexible material, for example of a material synthetic, possibly composite.
- cover sheet can have different structures depending on the goal. So she can present herself in the form of a more or less fine mesh net if, at through the covering device, we seek, simply, to avoid dirt, like dead leaves or others fall back into the basin 2.
- This sheet of cover 3 can also be transparent or translucent or, on the contrary, completely opaque. Either way, the present invention is in no way limited, nor to the configuration, neither to materials, nor even to the function plus particular to be completed by said cover sheet 3.
- the covering device 1 further comprises bars reinforcement 4 arranged transversely and to which is joined the covering sheet 3.
- the ends 5, 6, of these reinforcement bars 4 rest, moreover, on the longitudinal edges 7 and 8 of the basin 2.
- one of the transverse borders 10 of the cover sheet 3 is also made integral of a winding bar 12 of generally section cylindrical, on which is intended to roll up the sheet 3. More precisely, this winding bar 12 can be fitted, at at least one of its ends 13, an operating square 14 on which a manually operated drive mechanism (not shown) or motorized. Note that in case of rotation training motorized winding bar 12, the driving means can still take a position inside said bar so that its section is sufficient.
- this winding bar 12 is not necessarily located at the very end of the cover sheet 3.
- a section of tarpaulin can possibly extend this last beyond this winding bar 12, in particular in order to adjust the length of said sheet of overlap 3 to that of basin 2.
- this adjustment in length, of the sheet of recovery 3 is carried out, preferably, at its opposite end 15 with respect to said winding bar 12.
- said covering sheet 3 can be extended by a section of tarpaulins 16 beyond the last bar of transverse reinforcement 4, located at its end 15.
- This length adjustment of this cover sheet 3 by compared to the length of the pelvis 2 can also be obtained by adjusting accordingly, the spacing between two bars of reinforcement 4 successive or between the first bar of reinforcement 4 and the winding bar 12.
- this distance between the reinforcement bars 4 is respected while along the cover sheet 3, except between the two or three last reinforcement bars 4A, 4B, 4C if it is necessary that the spacing between them be changed to adjust the length of the cover sheet 3 to that of the basin 2.
- the bars of reinforcement 4, extending transversely above the cover sheet 3, are formed by profiles of approximately triangular section including a base 20 through which such a reinforcing bar 4 is intended to rest on the edges 7 and 8 of the basin 2.
- this base 20 is preferably planar.
- this profile comprises at least one side 21, facing towards the winding bar 12 when the covering device 1 is deployed forming with said base 20 an acute angle 22 less than 70 °.
- side 23 completing this triangular section of profiles constituting the reinforcement bars 4 its configuration can be any. However for matters of dress mechanical, it will preferentially extend, approximately perpendicular to base 20.
- the inclined side 21 it is not necessarily planar, such as shown in figure 4, but it can also be of concave or convex shape.
- This last solution, more particularly shown in Figure 5 has the advantage to increase the inertia of this profile and, ultimately, to improve its mechanical strength.
- this triangular configuration of the profile can lead to a shift in its center of gravity G with respect to the vertical median plane P.
- it is planned to define the thickness of the walls corresponding to sides 21 and 23 in such a way that their respective weight limits or cancels the offset of said center of gravity G with respect to said vertical plane P.
- the wall corresponding to side 21 is defined significantly thicker, especially in its lower part to obtain the desired result.
- side 23 can also be chosen slightly convex, as shown in Figure 5, to increase this inertia of the profile defining a reinforcing bar 4.
- FIG. 4 there is illustrated a bar of transverse reinforcement according to the invention, engaged in a scabbard 25 sewn transversely over a sheet of covering 3. It can thus be seen that the base 20 of the profile that constitutes a reinforcement bar 4 is thus located substantially in the same horizontal plane as said cover sheet 3. It is obvious, in such a configuration, that it does not no openings remain between the edges 7, 8 of the pool 2 and said covering sheet 3, capable of promoting the littering, like dead leaves or the like.
- a bar reinforcement 4 is constituted by a grooved profile which are joined together the transverse edges 26, 27, equipped a rod 28, sections of cover sheets 29 extending, precisely, between two reinforcing bars 4 successive. More particularly, on both sides, this grooved section has a groove 30, 30A capable of accommodating such a rod 28 and extending, preferably, along each of the longitudinal edges 31, 32 of the base 20. There again, this configuration ensures that the sheet of covering 3 and said base 20 of these sections constituting the reinforcement bars 4, are located substantially in the same horizontal plane, limiting the infiltration of litter or others inside the pool 2.
- said bars of reinforcement 4 rest, directly, at their ends 5, 6, on the borders 7, 8, of the basin 2. Since the reinforcement bars 4 are preferably of the metallic type and, especially, aluminum, it appears desirable to dress, at least their ends 5, 6, at the level of their base 20, of a protective sole 33.
- the present invention responds quite clearly to made effective at all of the problems and drawbacks of covering devices known so far. Also, the invention represents clear progress in the field considered.

Description
L'invention a trait à un dispositif de recouvrement enroulable destiné notamment à recouvrir un bassin tel qu'une piscine, comprenant, d'une part, une feuille de recouvrement souple aux dimensions adaptées à celles du bassin à recouvrir et apte à être enroulée autour d'une barre d'enroulement dont elle est solidaire à hauteur de l'une de ses bordures transversales et, d'autre part, des barres de renfort disposées transversalement et auxquelles est rendue solidaire ladite feuille de recouvrement, comme défini dans la revendication 1.The invention relates to a rollable covering device. intended in particular to cover a basin such as a swimming pool, comprising, on the one hand, a flexible covering sheet with dimensions adapted to those of the basin to be covered and suitable for be wrapped around a winding bar of which it is secured to one of its transverse edges and, on the other hand, reinforcement bars arranged transversely and to which is made integral said sheet of recovery, as defined in claim 1.
La présente invention trouvera son application dans le domaine des couvertures pour bassin, plus particulièrement de piscine.The present invention will find its application in the field covers for pools, especially swimming pools.
L'on connaít déjà un certain nombre de dispositifs de recouvrement correspondant à la description ci-dessus. Notamment, il est connu au travers du document FR-A-2.613.408, un dispositif de recouvrement enroulable pour des récipients, en particulier pour des piscines, comprenant une feuille de recouvrement au-dessus de laquelle sont conçus, transversalement, des fourreaux à même d'accueillir des barres de renfort sous forme de tubes de section circulaire. Tout particulièrement, l'une des bordures transversales de cette feuille de recouvrement reçoit, à l'intérieur d'un fourreau, une barre de renfort transversale dont au moins l'une des extrémités se présente saillante, latéralement, par rapport au bord longitudinal de ladite feuille de recouvrement. Cette extrémité saillante de ladite barre de renfort comporte, en outre, un carré de manoeuvre sur lequel peut être engagé un mécanisme d'entraínement, tel qu'un renvoi d'angle autorisant l'entraínement en rotation de ladite barre en vue de l'enroulement du dispositif de recouvrement par l'intermédiaire d'une manivelle. Ce mécanisme d'entraínement peut encore être motorisé. We already know a number of devices overlap corresponding to the description above. In particular, it is known from document FR-A-2,613,408, a roll-up covering device for containers, in particular for swimming pools, comprising a sheet of cover above which are designed, transversely, sheaths capable of accommodating bars reinforcement in the form of circular section tubes. All particularly, one of the transverse borders of this cover sheet receives, inside a sheath, a transverse reinforcement bar, at least one of the ends appear protruding laterally from the longitudinal edge of said cover sheet. This projecting end of said reinforcing bar comprises, in in addition, a maneuvering square on which a drive mechanism, such as a bevel gear allowing driving in rotation of said bar in view of the winding of the covering device via a crank. This drive mechanism can still be motorized.
Quoi qu'il en soit, en cours de manoeuvre d'enroulement, les différentes barres de renfort transversales, s'étendant au-dessus de la feuille de recouvrement représentent une succession d'obstacles qu'il y a lieu de franchir. En fin de compte, il s'avère particulièrement difficile de faire franchir systématiquement à la partie déjà enroulée du dispositif de recouvrement chacun de ces obstacles constitués par une barre de renfort transversale et il est nécessaire de fournir sur la manivelle constituant les moyens d'entraínement en rotation, un effort particulièrement important. En cas d'enroulement motorisé, il est évident, là encore, qu'il faut prévoir des moyens moteurs suffisamment puissants pour qu'ils soient en mesure de vaincre la résistance à l'enroulement que procurent ces obstacles.Anyway, during the winding maneuver, the different transverse reinforcement bars, extending above of the cover sheet represent a succession of obstacles that need to be overcome. In end of account, it is particularly difficult to get across systematically to the already wound part of the covering each of these obstacles constituted by a bar transverse reinforcement and it is necessary to provide on the crank constituting the rotary drive means, a particularly important effort. In case of winding motorized, it is obvious, again, that it is necessary to provide motor means powerful enough for them to be in able to overcome resistance to winding these obstacles.
Il est encore connu par le document FR-A-2.637.643 un dispositif de recouvrement en tous points similaire à celui qui vient d'être décrit, mais qui prévoit, cependant, de disposer les barres de renfort sous la feuille de recouvrement, dans des fourreaux équipant cette dernière au niveau de sa face inférieure. Cette solution permet de répondre au problème posé dans la mesure où, du côté où s'effectue l'enroulement de la feuille de recouvrement, celle-ci est dépourvue d'obstacles, évitant les franchissements successifs auxquels l'on a fait état préalablement. Cependant, étant précisément disposés sous la feuille de recouvrement, ces barres de renfort viennent s'interposer entre cette dernière et la bordure du bassin, favorisant ainsi le passage de détritus, feuilles mortes ou autres sous le dispositif de recouvrement. Or, en cas d'usage comme couverture d'hivernage, ces dispositifs de recouvrement ont pour fonction principale d'éviter que ces feuilles mortes et autres ne retombent à l'intérieur de la piscine. It is also known from document FR-A-2.637.643 a recovery device in all respects similar to that which has just been described, but which plans, however, to have the reinforcement bars under the cover sheet, in sheaths equipping the latter at its face lower. This solution makes it possible to respond to the problem posed insofar as, on the side where the winding of the cover sheet, it is free of obstacles, avoiding successive crossings that have been made state before. However, being precisely arranged under the cover sheet, these reinforcement bars come to intervene between the latter and the edge of the basin, thus favoring the passage of litter, dead leaves or others under the covering device. However, in case of use as winter cover, these covering devices main function is to prevent these dead leaves and others don't fall back inside the pool.
De manière à répondre à ce problème, il est prévu, selon ce document FR-A-2.637.643, d'équiper les extrémités des profilés tubulaires, constituant les barres de renfort transversales, de parties planes excentrées. A noter, en outre, qu'au niveau de ces zones d'appui du dispositif de recouvrement sur les bordures du bassin, ces extrémités desdites barres de renfort transversales peuvent passer au-dessus de la feuille de recouvrement. Le problème lié à une telle conception est, bien évidemment, son coût. Tout particulièrement, au cas où les extrémités planes des barres de renfort transversales sont obtenues par déformation du profilé qui les constitue, il en résulte des contraintes au niveau de la nature du matériau utilisé ou encore dans l'épaisseur des parois composant le profilé. Naturellement, il est nécessaire de disposer d'un outillage à même de créer cette déformation. Dans certains cas, il est prévu d'aboutir aux extrémités des barres de renfort des embouts, par exemple en matériau synthétique, comportant un méplat excentré. Là encore, la conception et l'assemblage de ces embouts représentent des opérations supplémentaires qui viennent augmenter le coût de revient du dispositif de recouvrement.In order to respond to this problem, it is planned, according to what document FR-A-2.637.643, to equip the ends of the profiles tubular, constituting the transverse reinforcement bars, of eccentric flat parts. It should also be noted that at the level of these support zones of the covering device on the edges of the basin, these ends of said reinforcing bars transverse can pass over the sheet of recovery. The problem with such a design is, well obviously, its cost. In particular, in case the flat ends of the transverse reinforcement bars are obtained by deformation of the profile which constitutes them, there results from constraints in terms of the nature of the material used or in the thickness of the walls making up the streamlined. Naturally, it is necessary to have a tool capable of creating this deformation. In some cases, it is planned to end at the ends of the reinforcement bars of the end caps, for example of synthetic material, comprising a eccentric flat. Again, the design and assembly of these tips represent additional operations which come to increase the cost price of the device recovery.
Finalement, l'on connaít au travers du document FR-A-2.690.943 un dispositif de recouvrement similaire à ceux décrits précédemment, mais dont la feuille de recouvrement est du type modulaire et constituée d'éléments de bâche dont les bords transversaux sont équipés de joncs à même d'être insérés dans des profilés à gorges de section sensiblement circulaire constituant des barres de renfort transversales. Une telle conception qui répond davantage aux inconvénients que représente la feuille de recouvrement en un seul tenant en cas de déchirure ne satisfait pas, pour autant, au problème posé préalablement. Finally, we know through document FR-A-2.690.943 a covering device similar to those described previously, but whose cover sheet is of the type modular and made of tarpaulin elements with edges cross are equipped with rods able to be inserted in grooved sections of substantially circular cross-section constituting transverse reinforcing bars. Such a design that addresses disadvantages more than represents the cover sheet in one piece in case of tear does not, however, satisfy the problem posed beforehand.
Ainsi, les gorges à même d'accueillir les joncs transversaux équipant les éléments de bâche, se situent de part et d'autre et sensiblement dans le plan médian horizontal des profilés constituant lesdites barres de renfort. Aussi, au niveau des zones d'appui en bordure du bassin, persiste entre ces dernières et la feuille de recouvrement un espace autorisant le passage de déchets et autres. En outre, ces profilés à gorges créent, là encore, des obstacles transversalement à la direction d'enroulement du dispositif de recouvrement, obstacles qui sont particulièrement difficiles à franchir, notamment lorsque ce résultat doit être obtenu à force du poignet par l'intermédiaire d'une manivelle.Thus, the gorges able to accommodate the transverse rods fitted to the tarpaulin elements, are located on both sides and substantially in the horizontal median plane of the profiles constituting said reinforcing bars. Also, at the level of support zones at the edge of the basin, persists between these and the cover sheet a space allowing the passage of waste and others. In addition, these grooved profiles Again, create obstacles transverse to the winding direction of the covering device, obstacles that are particularly difficult to overcome, especially when this result must be obtained by dint of wrist through a crank.
La présente invention se propose de remédier à l'ensemble des inconvénients précités. L'invention telle que définie dans les revendications, résout le problème et consiste en un dispositif de recouvrement enroulable destiné, notamment, à recouvrir un bassin, tel qu'une piscine, comprenant, d'une part, une feuille de recouvrement souple aux dimensions adaptées à celles du bassin à recouvrir et apte à être enroulée autour d'une barre d'enroulement dont elle est solidaire à hauteur de l'une de ses bordures transversales et, d'autre part, des barres de renfort disposées transversalement et auxquelles est rendue solidaire ladite feuille de recouvrement, lesdites barres de renfort étant constituées par des profilés de section approximativement triangulaire comprenant, d'une part, une base par l'intermédiaire de laquelle ces profilés sont destinés à reposer en bordure du bassin à couvrir et, d'autre part, au moins un côté, orienté en direction de ladite barre d'enroulement lorsque le dispositif de recouvrement est déployé, formant avec la base un angle aigu inférieur à 70°.The present invention proposes to remedy all of the aforementioned drawbacks. The invention as defined in claims, solves the problem and consists of a device rollable covering intended in particular to cover a basin, such as a swimming pool, comprising, on the one hand, a sheet flexible cover with dimensions adapted to those of basin to be covered and suitable for being wrapped around a bar winding of which it is integral up to one of its transverse edges and, on the other hand, reinforcement bars arranged transversely and to which is made integral said cover sheet, said reinforcing bars being formed by section profiles approximately triangular comprising, on the one hand, a base by through which these sections are intended for rest on the edge of the basin to be covered and, on the other hand, at least one side, oriented towards said bar when the covering device is deployed, forming an acute angle of less than 70 ° with the base.
Selon une autre caractéristique de la présente invention, les barres de renfort sont engagées dans des fourreaux aménagés transversalement sur la face supérieure de la feuille de recouvrement.According to another characteristic of the present invention, the reinforcement bars are engaged in fitted sleeves transversely on the upper face of the sheet recovery.
En outre, selon l'invention, le profilé constituant une barre de renfort est un profilé à gorges comportant une gorge s'étendant, sensiblement, le long des bords longitudinaux de ladite base du profilé, lesdites gorges étant à même de recevoir un jonc équipant chacun des bords transversaux de tronçons de feuilles de recouvrement s'étendant entre deux barres de renfort successives.In addition, according to the invention, the profile constituting a bar reinforcement is a grooved profile having a groove extending, substantially, along the longitudinal edges of said base of the profile, said grooves being able to receive a rod fitted to each of the transverse edges of sections of cover sheets extending between two successive reinforcement bars.
Préférentiellement, au moins les barres de renfort se situant du côté de la première moitié de la feuille de recouvrement, ceci par rapport à la barre d'enroulement, respectent, entre elles, une distance comprise entre 1,2 et 1,3 mètres.Preferably, at least the reinforcement bars lying on the side of the first half of the cover sheet, this with respect to the winding bar, respect, between them, a distance between 1.2 and 1.3 meters.
Les avantages résultant de la présente invention consistent, essentiellement, en ce qu'en raison de la configuration particulière des barres de renfort transversales, celles-ci ne créent plus, comme auparavant, des obstacles qu'il convient simplement de franchir. En effet, le rouleau que constitue la longueur de la feuille de recouvrement déjà enroulée vient, dans ce cas, au contact avec le côté incliné d'une barre de renfort et, en poursuivant le mouvement d'enroulement, ce rouleau au lieu de passer, simplement au-dessus de ladite barre de renfort, provoque le basculement de cette dernière dans la direction d'enroulement de sorte qu'elle n'offre qu'une moindre résistance à la progression en cours.The advantages resulting from the present invention consist, basically, in that due to the configuration particular of the transverse reinforcement bars, these do not create, as before, more obstacles than appropriate just to cross. Indeed, the roller that constitutes the length of the already wound cover sheet comes, in this case, in contact with the inclined side of a bar reinforcement and, continuing the winding movement, this roller instead of passing, just above said bar reinforcement, causes the latter to tilt in the winding direction so that it offers only a lesser resistance to the current progression.
Il est évident dans ces conditions, que les manoeuvres, lorsqu'elles sont exécutées manuellement, s'avèrent plus commodes et, surtout, plus aisées. En cas de motorisation, le moteur est moindrement sollicité à chaque passage au-dessus d'une barre de renfort transversale de sorte que sa puissance et donc son poids peuvent être plus réduits sans compter que la consommation en énergie électrique est, elle aussi, plus faible. Ceci représente un avantage tout particulier en cas d'alimentation en énergie électrique autonome, par exemple, à l'aide d'une batterie.It is obvious under these conditions, that the maneuvers, when executed manually, are more convenient and, above all, easier. In case of motorization, the motor is less stressed each time it passes over of a transverse reinforcement bar so that its power and therefore its weight can be reduced more than the consumption of electrical energy is also higher low. This is a very special advantage in case supply of autonomous electrical energy, for example, to using a battery.
Finalement, en choisissant un écartement bien défini entre les barres de renfort se situant, tout particulièrement, dans la partie amont de la feuille de recouvrement, ceci par rapport à la barre d'enroulement, il est possible d'assurer une meilleure répartition de ces barres de renfort autour de l'arbre d'enroulement, de sorte que le rouleau que forme, progressivement, la feuille de recouvrement en cours de manoeuvre, soit davantage cylindrique. Il est évident, en effet, qu'une forme ovoïde rend, là encore, la manoeuvre difficile en raison d'une progression par à coups.Finally, by choosing a well-defined spacing between the reinforcement bars located, in particular, in the upstream part of the cover sheet, this with respect to the winding bar, it is possible to ensure better distribution of these reinforcement bars around the tree of winding, so that the roll that forms, gradually, the cover sheet being maneuver, or more cylindrical. It is obvious, in effect, that an ovoid shape again makes the maneuver difficult due to jogging.

ou autres ne retombent dans le bassin 2. Cette feuille de
recouvrement 3 peut également être transparente ou translucide
ou, au contraire, totalement opaque. Quoi qu'il en soit, la
présente invention n'est nullement limitée, ni à la
configuration, ni aux matériaux, ni même à la fonction plus
particulière que doit remplir ladite feuille de recouvrement 3.Thus, this covering device 1 comprises a sheet of
covering 3 of flexible material, for example of a material
synthetic, possibly composite. In fact, such
cover sheet can have different structures
depending on the goal. So she can present herself
in the form of a more or less fine mesh net if, at
through the covering device, we seek,
simply, to avoid dirt, like dead leaves
or others fall back into the
Le dispositif de recouvrement 1 comporte, en outre, des barres
de renfort 4 disposées transversalement et auxquelles est
rendue solidaire la feuille de recouvrement 3. Les extrémités
5, 6, de ces barres de renfort 4 reposent, par ailleurs, sur
les bordures longitudinales 7 et 8 du bassin 2. The covering device 1 further comprises
Il convient d'observer que l'une des bordures transversales 10
de la feuille de recouvrement 3 est, en outre, rendue solidaire
d'une barre d'enroulement 12 de section généralement
cylindrique, sur laquelle est destinée à s'enrouler la feuille
de recouvrement 3. Plus précisément, cette barre d'enroulement
12 peut être équipée, à l'une au moins de ses extrémités 13,
d'un carré de manoeuvre 14 sur lequel peut être enfilé un
mécanisme d'entraínement (non représenté) à commande manuelle
ou motorisée. A noter qu'en cas d'entraínement en rotation
motorisé de la barre d'enroulement 12, les moyens moteurs
peuvent encore prendre position à l'intérieur de ladite barre
pour que sa section soit suffisante.It should be noted that one of the
On note, en outre, que, contrairement à la représentation de la
figure 2, cette barre d'enroulement 12 n'est pas nécessairement
située à l'extrémité même de la feuille de recouvrement 3.
Ainsi, un tronçon de bâche peut éventuellement prolonger cette
dernière au-delà de cette barre d'enroulement 12, notamment
dans le but d'ajuster la longueur de ladite feuille de
recouvrement 3 à celle du bassin 2. Toutefois, selon
l'invention, cet ajustement en longueur, de la feuille de
recouvrement 3 s'effectue, préférentiellement, au niveau de son
extrémité opposée 15 par rapport à ladite barre d'enroulement
12. Ainsi, ladite feuille de recouvrement 3 peut être prolongée
par un tronçon de bâches 16 au-delà de la dernière barre de
renfort transversale 4, se situant à son extrémité 15. Cet
ajustement en longueur de cette feuille de recouvrement 3 par
rapport à la longueur du bassin 2 peut également être obtenue
en ajustant en conséquence, l'écartement entre deux barres de
renfort 4 successives ou encore entre la première barre de
renfort 4 et la barre d'enroulement 12.We note, moreover, that, contrary to the representation of the
Figure 2, this
Toutefois, selon l'invention, au moins les barres de renfort 4
se situant, par rapport à la direction d'enroulement et, donc,
par rapport à la barre d'enroulement 12, dans la première
moitié 18 de la feuille de recouvrement 3, respectent entre
elles, un écartement compris entre 1,2 et 1,3 mètres,
préférentiellement entre 1,22 et 1,27 mètres. En définitive,
cette distance entre les barres de renfort 4 est respectée tout
au long de la feuille de recouvrement 3, hormis entre les deux
ou trois dernières barres de renfort 4A, 4B, 4C s'il est
nécessaire que l'écartement entre ces dernières soit modifié
pour ajuster la longueur de la feuille de recouvrement 3 à
celle du bassin 2. Les avantages découlant d'une telle
configuration consistent en ce qu'en cours d'enroulement de la
feuille de recouvrement 3, l'on obtienne, une répartition
approximativement régulière de ces barres de renfort 4 autour
de la barre d'enroulement 12, tel que représenté dans la figure
3, de sorte que le rouleau 19 que crée progressivement ce
dispositif de recouvrement 1 enroulé, présente une forme
générale cylindrique dont les progressions le long des bordures
7, 8, du bassin 2 soient facilitées.However, according to the invention, at least the reinforcing
Précisément, dans le but de faciliter la manoeuvre
d'enroulement de ce dispositif de recouvrement 1, les barres de
renfort 4, s'étendant, transversalement, au-dessus de la
feuille de recouvrement 3, sont constituées par des profilés de
section approximativement triangulaire comprenant une base 20
par l'intermédiaire de laquelle une telle barre de renfort 4
est destinée à reposer sur les bordures 7 et 8 du bassin 2. Par
conséquent, cette base 20 est préférentiellement plane. En
outre et selon l'invention, ce profilé comporte au moins un
côté 21, orienté en direction de la barre d'enroulement 12
lorsque le dispositif de recouvrement 1 est déployé formant
avec ladite base 20 un angle 22 aigu inférieur à 70°. Quant au
côté 23 venant compléter cette section triangulaire des
profilés constituant les barres de renfort 4, sa configuration
peut être quelconque. Cependant pour des questions de tenue
mécanique, il s'étendra préférentiellement, approximativement
perpendiculairement par rapport à la base 20.Specifically, in order to facilitate the maneuver
winding of this covering device 1, the bars of
Quant au côté incliné 21 il n'est pas nécessairement plan, tel
que représenté dans la figure 4, mais il peut également être de
forme concave ou convexe. Cette dernière solution, plus
particulièrement représentée dans la figure 5 a pour avantage
d'augmenter l'inertie de ce profilé et, finalement, d'améliorer
sa tenue mécanique.As for the
En outre, cette configuration triangulaire du profilé, selon
l'invention, peut conduire à un décalage de son centre de
gravité G par rapport au plan médian vertical P. Or, pour
éviter le risque de basculement dudit profilé sous l'impulsion
d'une pression appliquée sur le dispositif de recouvrement 1,
il est prévu, avantageusement, de définir l'épaisseur des
parois correspondant aux côtés 21 et 23 de telle manière que
leur poids respectif limite ou annule le décalage dudit centre
de gravité G par rapport audit plan vertical P. Ainsi, tel que
visible dans la figure 5, la paroi correspondant au côté 21 est
définie sensiblement plus épaisse, tout particulièrement, dans
sa partie inférieure pour obtenir le résultat recherché.In addition, this triangular configuration of the profile, according to
the invention can lead to a shift in its center of
gravity G with respect to the vertical median plane P. Now, for
avoid the risk of tilting said profile under the impulse
of a pressure applied to the covering device 1,
advantageously, it is planned to define the thickness of the
walls corresponding to
De plus, le côté 23 peut, lui aussi, être choisi légèrement
convexe, comme représenté sur la figure 5, pour augmenter cette
inertie du profilé définissant une barre de renfort 4.In addition,
Ainsi, tel que représenté dans la figure 3, au cours de la
progression du rouleau 19 que constitue la partie de la feuille
de recouvrement 3 déjà enroulée autour de la barre
d'enroulement 12, ce rouleau 19 franchit plus aisément une
telle barre de renfort 4, conforme à l'invention, dans la
mesure où ce rouleau 19 n'est plus dans l'obligation de
contourner totalement ladite barre de renfort 4 mais en
s'appuyant sur la pente définie par le côté incliné 21, il
provoque le basculement de cette barre de renfort 4 autour de
l'arrête définie par le côté vertical 23 et la base 20. Cette
manoeuvre d'enroulement du dispositif de recouvrement 1, selon
l'invention s'effectue, en quelque sorte, avec une certaine
continuité rendant les manipulations plus commodes.Thus, as shown in Figure 3, during the
progression of the
Dans le cadre de la figure 4, il est illustré une barre de
renfort transversale conforme à l'invention, engagée dans un
fourreau 25 cousu transversalement au-dessus d'une feuille de
recouvrement 3. L'on voit, ainsi, que la base 20 du profilé que
constitue une barre de renfort 4 se situe, ainsi, sensiblement
dans un même plan horizontal que ladite feuille de recouvrement
3. Il est évident, dans une telle configuration, qu'il ne
persiste pas d'ouvertures entre les bordures 7, 8 du bassin 2
et ladite feuille de recouvrement 3, à même de favoriser le
passage de détritus, du type feuilles mortes ou autres.In the context of FIG. 4, there is illustrated a bar of
transverse reinforcement according to the invention, engaged in a
La configuration selon la figure 5 diffère en ce qu'une barre
de renfort 4 est constituée par un profilé à gorges auquel sont
rendues solidaires les bordures transversales 26, 27, équipées
d'un jonc 28, de tronçons de feuilles de recouvrement 29
s'étendant, précisément, entre deux barres de renfort 4
successives. Plus particulièrement, de part et d'autre, ce
profilé à gorge comporte une gorge 30, 30A à même d'accueillir
un tel jonc 28 et s'étendant, préférentiellement, le long de
chacune des bordures longitudinales 31, 32 de la base 20. Là
encore, cette configuration fait en sorte que la feuille de
recouvrement 3 et ladite base 20 de ces profilés constituant
les barres de renforts 4, se situent sensiblement dans un même
plan horizontal, limitant les infiltrations de détritus ou
autres à l'intérieur du bassin 2.The configuration according to Figure 5 differs in that a
A noter que dans un tel cas de figure, lesdites barres de
renfort 4 reposent, directement, au niveau de leurs extrémités
5, 6, sur les bordures 7, 8, du bassin 2. Etant donné que les
barres de renfort 4 sont préférentiellement du type métallique
et, tout particulièrement, en aluminium, il apparaít
souhaitable d'habiller, au moins leurs extrémités 5, 6, au
niveau de leur base 20, d'une semelle de protection 33.Note that in such a case, said bars of
Celle-ci est conçue, préférentiellement, en un matériau
synthétique et peut être fixée par tous moyens connus par
l'Homme du Métier en applique sur cette base 20 des barres de
renfort 4. Cependant, de manière à limiter les opérations
d'assemblage et, bien sûr, le coût d'un dispositif de
recouvrement 1, lesdites semelles 33 se présentent
avantageusement, sous forme de profilés à même de venir
s'enfiler sur les extrémités 5, 6, de ces barres de renfort 4
en venant s'agripper sur les bords longitudinaux 31, 32 de la
base 20. A noter qu'au niveau de cette dernière peut encore
être aménagée au moins une rainure en «T» 34 à même
d'accueillir une nervure 35 de forme conjuguée dont est pourvue
cette semelle 33 en matière plastique profilée.This is preferably designed from a material
synthetic and can be fixed by any means known by
the skilled person applies on this base 20 bars of
Par conséquent, la présente invention répond de manière tout à fait efficace à l'ensemble des problèmes et inconvénients de dispositifs de recouvrement connus jusqu'ici. Aussi, l'invention représente un net progrès dans le domaine considéré.Consequently, the present invention responds quite clearly to made effective at all of the problems and drawbacks of covering devices known so far. Also, the invention represents clear progress in the field considered.
