Description

L'invention a pour objet un dispositif permettant le recouvrement temporaire de surfaces présentant l'intérêt d'être, grâce à un moyen d'enroulement desmodromique, mis en place ou retiré très rapidement.The invention relates to a device for the temporary recovery of surfaces having the advantage of being, thanks to a desmodromic winding means, put in place or removed very quickly.

On connaît des dispositifs constitués par des rouleaux dévidoirs de toile, axés aux extrémités de la surface à recouvrir. Selon ce moyen, si le réenroulement de la toile n'est pas obtenu par une manivelle commandant le tambour support, la traction exercée manuellement sur l'extrémité de la toile doit permettre à celles-ci d'entraîner le rouleau équipé d'un système de caoutchoucs ou de ressorts qui se trouvent ainsi tendus; lors du réenroulement, l'action de ceux-ci entraînant la rotation en sens inverse du tube supportant la toile.Devices are known which consist of cloth reel rollers, centered at the ends of the surface to be covered. According to this means, if the rewinding of the fabric is not obtained by a crank controlling the support drum, the traction exerted manually on the end of the fabric must allow these to drive the roller equipped with a system. rubbers or springs which are thus stretched; during rewinding, the action of these causing the rotation in the opposite direction of the tube supporting the fabric.

Lors de la mise en oeuvre de ce matériel, il a toutefois été constaté :

  • 1°) - que le réenroulement de la toile, destinée à recevoir l'eau de pluie était, de par la masse d'eau retenue, devenu beaucoup plus difficile.
  • 2°) - que l'obligation d'utiliser une pluralité d'éléments entraînait, outre un laps de temps plus long pour la mise en place, de graves défauts d'étanchéité.
  • 3°) - que le fait d'avoir à disposer ces moyens sur des tambours d'enroulement à une certaine hauteur afin de permettre leur bon fonctionnement déterminait une prise au vent très importante et nécessitait l'utilisation de supports, amovibles certes, mais néanmoins encombrants.
During the implementation of this material, it was however noted:
  • 1 °) - that the rewinding of the canvas, intended to receive rainwater had, by the mass of water retained, become much more difficult.
  • 2 °) - that the obligation to use a plurality of elements resulted, in addition to a longer period of time for the installation, of serious leaks.
  • 3 °) - that the fact of having to have these means on winding drums at a certain height in order to allow their proper functioning determined a very high wind resistance and necessitated the use of supports, certainly removable, but nevertheless bulky.

Selon la présente invention, le dispositif de recouvrement se différencie de ces dispositifs anciens par le fait que le tambour d'enroulement est mobile et que son déplacement est favorisé par l'utilisation de chariots de guidage mobiles également.According to the present invention, the covering device differs from these old devices by the fact that the winding drum is mobile and that its movement is favored by the use of mobile guide carriages also.

L'un ou plusieurs de ces chariots peuvent être avantageusement dotés d'un moyen d'entraînement mécanique ou électrique.One or more of these carriages can advantageously be fitted with mechanical or electrical drive means.

Le fait que le tambour supportant la toile de recouvrement se déplace permet, lors du réenroulement, de chasser l'eau alourdissant celle-ci au fur et à mesure de son avancement, rendant ainsi l'effort à effectuer pratiquement nul.The fact that the drum supporting the covering fabric moves, during rewinding, to expel the water weighing it down as it advances, thus making the effort to be practically zero.

Par ailleurs, le dispositif devient totalement autonome et ne nécessite aucun point d'accrochage sur le terrain à recouvrir.Furthermore, the device becomes completely autonomous and does not require any attachment point on the ground to be covered.

Enfin, la toile et le tambour d'enroulement reposant ou se trouvant à toute proximité du sol, il n'est plus nécessaire d'envisager une pluralité d'éléments de recouvrement et la prise au vent devient nulle.Finally, the fabric and the winding drum resting or being very close to the ground, it is no longer necessary to envisage a plurality of covering elements and the wind resistance becomes zero.

Conformément à l'invention, le dispositif est constitué par une toile fixée par une de ses extrémités temporairement au ras du terrain à protéger, cette toile étant enroulée sur un tambour supporté par un arbre monté dans des paliers prévus sur deux chariots d'extrémité comprenant chacun au moins une roue avant et une roue arrière roulant l'une sur le terrain à protéger et l'autre sur la toile tandis que chaque chariot porte des roues ou galets de tension maintenant le centrage de chaque chariot et de ce fait la tension de la toile lors de l'enroulement ou du déroulement de celle-ci sur le terrain. Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.According to the invention, the device consists of a canvas fixed by one of its ends temporarily flush with the ground to be protected, this canvas being wound on a drum supported by a shaft mounted in bearings provided on two end carriages comprising each at least one front wheel and one rear wheel rolling one on the ground to be protected and the other on the canvas while each carriage carries tension wheels or rollers maintaining the centering of each carriage and therefore the tension of the canvas when winding or unwinding it on the ground. Various other characteristics of the invention will also emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées à titre d'exemples aux dessins annexés.Embodiments of the object of the invention are shown by way of examples in the accompanying drawings.

La fig. 1 représente en perspective une partie d'un cours de tennis sur lequel se trouve installé le dispositif de recouvrement de l'invention.Fig. 1 is a perspective view of part of a tennis court on which the covering device of the invention is installed.

La fig. 2 représente une élévation latérale de l'un des chariots moteurs, sachant que dans cette forme de réalisation, le mouvement est obtenu par un ou plusieurs moteurs situés à l'intérieur du tube d'enroulement de la toile.Fig. 2 shows a side elevation of one of the motor carriages, knowing that in this embodiment, the movement is obtained by one or more motors located inside the winding tube of the fabric.

La fig. 2a est une élévation de face partielle de la fig. 2.Fig. 2a is a partial front elevation of FIG. 2.

La fig. 3 représente une vue d'extrémité de l'un des chariots moteurs, sachant que dans cette forme de réalisation le mouvement est obtenu pour le déplacement du tube d'enroulement par l'intermédiaire de manivelles, de chaînes et de pignons coniques.Fig. 3 shows an end view of one of the motor carriages, knowing that in this embodiment the movement is obtained for the displacement of the winding tube by means of cranks, chains and bevel gears.

La fig. 3a est une élévation de face partielle correspondant à la fig. 3.Fig. 3a is a partial front elevation corresponding to FIG. 3.

La fig. 4 représente en plan l'une des extrémités du dispositif et montre la possibilité d'installer l'un des chariots à une certaine distance de la lisière de la toile de protection afin que malgré l'état du terrain rendu humide et mou hors de la limite de protection les roues du chariot circulent dans une zone protégée de la pluie par la toile.Fig. 4 shows in plan one of the ends of the device and shows the possibility of installing one of the carriages at a certain distance from the edge of the protective fabric so that despite the state of the ground made wet and soft outside the protection limit the wheels of the trolley run in an area protected from rain by the fabric.

A la fig. 1, le sol d'un court de tennis 1 est recouvert partiellement de part et d'autre du filet 2 de toiles 3, 3' déroulées par les tubes 4, 4' reposant sur le sol. Les arbres 5, 5' des moteurs (non représentés) encastrés dans les tubes 4, 4' sont montés non pivotants par l'intermédiaire des bras de chariot 6, 6' maintenus en position sensiblement parallèle au sol par des roues 7, 7' reposant sur la toile et par des roues 8, 8' reposant sur le sol à une certaine distance de la lisière 9, 9' de la toile du fait d'axes-entretoises 10, 10'.In fig. 1, the floor of a tennis court 1 is partially covered on either side of the net 2 of fabrics 3, 3 'unrolled by the tubes 4, 4' resting on the ground. The shafts 5, 5 'of the motors (not shown) embedded in the tubes 4, 4' are mounted non-pivotally by means of the carriage arms 6, 6 'held in position substantially parallel to the ground by wheels 7, 7' resting on the canvas and by wheels 8, 8 'resting on the ground at a certain distance from the edge 9, 9' of the canvas due to spacer pins 10, 10 '.

Des berceaux 11, 11' maintiennent l'écartement à l'autre extrémité du chariot et peuvent avantageusement supporter des roulettes réglables 12, 12' de centrage de l'ensemble.Cradles 11, 11 'maintain the spacing at the other end of the carriage and can advantageously support adjustable rollers 12, 12' for centering the assembly.

L'alimentation électrique des moteurs est obtenue par des fils électriques passant en lisière 9, 9' de la toile. Ces fils souples servent également de raidisseurs. D'autres raidisseurs souples (fil nylon, câblette d'acier, etc...) peuvent également être disposés par tout moyen convenable à certains endroits des toiles.The power supply to the motors is obtained by electric wires passing along the edge 9, 9 ′ of the fabric. These flexible wires also serve as stiffeners. Other flexible stiffeners (nylon thread, steel cable, etc.) can also be arranged by any suitable means in certain places of the fabrics.

Les extrémités opposées aux tubes de déroulage sont avantageusement maintenues au fond du terrain par des sangles 13 accrochées à la toile 3 et à la clôture 14 du terrain.The ends opposite to the unwinding tubes are advantageously held at the bottom of the ground by straps 13 attached to the fabric 3 and to the fence 14 of the ground.

Selon la fig. 2, le tube 4, en position d'enroulement de la toile 3 disposée à même le sol 1 est mu par le moteur encastré, dont l'arbre 5 est monté dans un palier solidaire du bras 6 du chariot. La roue 7 prend alors appui sur la toile 3, faisant ainsi réaction au couple moteur, alors que la roue 8 est dégagée du sol.According to fig. 2, the tube 4, in the fabric winding position 3 disposed on the ground 1 is moved by the built-in motor, the shaft 5 of which is mounted in a bearing secured to the arm 6 of the carriage. The wheel 7 then bears on the fabric 3, thus reacting to the engine torque, while the wheel 8 is released from the ground.

Les roues ou galetsde tension 12, réglables par rapport à leur support 11, maintiennent le centrage du chariot par rapport au tube 4. En vue d'élévation, l'on peut constater la disposition des roues 7 par rapport à l'extrémité du tube 4 et à la lisière 9 de la toile 3 qui, grâce à la longueur des axes-entretoises 10, permet à ces roues de circuler dans la partie recouverte du terrain, donc sèche, la référence 13 désigne l'entrée d'alimentation électrique du moteur.The tension wheels or rollers 12, adjustable relative to their support 11, maintain the centering of the carriage relative to the tube 4. In view of elevation, the arrangement of the wheels 7 can be seen with respect to the end of the tube 4 and at the edge 9 of the fabric 3 which, thanks to the length of the axle-spacers 10, allows these wheels to circulate in the covered part of the ground, therefore dry, the reference 13 designates the entry motor power supply.

Selon la fig. 3, le dispositif d'entraînement du tube 4 est constitué par un jeu de pignons et chaînes 15 placés aux extrémités du tube 4, ces pignons et chaînes étant entraînés par un couple de pignons coniques 16 entraînant un arbre 17 de longueur légèrement supérieure à celle du tube 4. Des biellettes 18 assurent la tension des chaînes 15.According to fig. 3, the device for driving the tube 4 is constituted by a set of sprockets and chains 15 placed at the ends of the tube 4, these sprockets and chains being driven by a pair of bevel sprockets 16 driving a shaft 17 of length slightly greater than that of the tube 4. Rods 18 ensure the tension of the chains 15.

Un système de renvoi et manivelles 19 permet d'obtenir le mouvement de rotation de l'ensemble qui se trouve supporté par des chariots 20 reliés entre eux par une entretoise 21. Dans cette forme de réalisation, les roues 7 et 8 portent également sur la toile 3 et le sol 1.A return system and cranks 19 makes it possible to obtain the rotational movement of the assembly which is supported by carriages 20 connected to each other by a spacer 21. In this embodiment, the wheels 7 and 8 also bear on the canvas 3 and soil 1.

Dans la forme de réalisation de la fig. 3 la rotation de l'arbre moteur 5 entraînant le tube 4 portant la toile de protection 3 peut également être obtenue à l'aide d'un vilebrequin et d'un arbre de transmission ou même, à la place du système de renvoi et manivelles 19, par un moteur électrique thermique ou autre.In the embodiment of FIG. 3 the rotation of the motor shaft 5 driving the tube 4 carrying the protective fabric 3 can also be obtained using a crankshaft and a transmission shaft or even, instead of the deflection system and cranks 19, by an internal combustion engine or the like.

A la fig. 4, la toile 3 dont l'extrémité est accrochée à la cloture 14 par l'intermédiaire de sangles 13 est représentée en début de déroulage.In fig. 4, the fabric 3, the end of which is attached to the fence 14 by means of straps 13, is shown at the start of unwinding.

Dans cet exemple de réalisation, le moteur 22 alimenté par un fil électrique 122 situé en lisière 9 de la toile 3 est extérieur au tube. L'entraînement de celui-ci est alors obtenu par un train d'engrenage 23 situé aux extrémités du tube 4. Là également, apparait la disposition des roues 7 et 8 du chariot tenues à une certaine distance du bord de la toile par les axes 10 et au berceau muni également de roulettes 12.In this exemplary embodiment, the motor 22 supplied by an electric wire 122 located at the edge 9 of the fabric 3 is outside the tube. The drive thereof is then obtained by a gear train 23 located at the ends of the tube 4. Again, there appears the arrangement of the wheels 7 and 8 of the carriage held at a certain distance from the edge of the fabric by the axes 10 and to the cradle also provided with rollers 12.

Il y a lieu également de noter que l'enroulement et le déroulement de la toile 3 peuvent être obtenus par simple poussée ou traction exercée sur le chariot portant la toile de protection 3. Dans ce cas, les roues 7 du chariot deviennent motrices afin d'entraîner directement ou indirectement l'arbre 5 portant le tambour 4 sur lequel s'enroule la toile 3.It should also be noted that the winding and unwinding of the fabric 3 can be obtained by simple pushing or pulling exerted on the carriage carrying the protective fabric 3. In this case, the wheels 7 of the carriage become driving in order to '' directly or indirectly drive the shaft 5 carrying the drum 4 on which the fabric 3 is wound.

Afin d'obtenir une meilleure adhérence au sol l'arbre 5 du tambour 4 qui est en principe constitué par un tube en alliage léger permettant un transport aisé peut être momentanément alourdi par remplissage d'eau, de sable ou autres éléments fluides qui se placent à l'intérieur de la partie creuse étanche du tube formant tambour.In order to obtain better adhesion to the ground, the shaft 5 of the drum 4 which in principle consists of a light alloy tube allowing easy transport can be temporarily weighed down by filling with water, sand or other fluid elements which are placed inside the sealed hollow part of the drum tube.

Bien entendu, lorsqu'il s'agit de recouvrir pour la protéger une zone inaccessible en son milieu par exemple une piscine il est prévu que les chariots moteurs tels que représentés aux fig. 2, 2a, 3, 3a sont disposés de part et d'autre du bassin et on dévide et réenroule la toile 3 de la même façon que ce qui a été expliqué précédemment.Of course, when it comes to covering to protect it an inaccessible area in the middle, for example a swimming pool, it is expected that the motor carriages as shown in FIGS. 2, 2a, 3, 3a are arranged on either side of the basin and the fabric 3 is unwound and rewound in the same way as that which has been explained previously.
