Abstract

Parallel strips (15) of flexible material are stretched in front of the walls on which the balls end their travel, that is to say particularly the back walls (14) of the court and/or the tennis net (12) itself. The tennis balls cross the barrier consisting of the strips (15) and accumulate in the space (16) left between these strips and the vertical stopping surface (14). <IMAGE>

Description

L'invention concerne une installation de récupération de balles destinée notamment à équiper un court de tennis.The invention relates to a ball recovery installation intended in particular to equip a tennis court.

Le tennis compte de plus en plus d'adeptes, mais le ramassage des balles par les joueurs amateurs est une opération fastidieuse qui interrompt régulièrement la partie ou l'entraînement, lorsqu'un ramasseur n'est pas disponible. D'autre part, lorsque les joueurs disposent d'une réserve de balles importante, il se pose alors un problème de sécurité, en raison du grand nombre de balles qui finissent par joncher le sol du court de tennis, et qui peuvent gêner l'évolution des joueurs, voire provoquer des accidents (entorses, fractures) résultant de mauvaises chutes.Tennis has more and more fans, but the collection of balls by amateur players is a tedious operation that regularly interrupts the game or training, when a pickup is not available. On the other hand, when the players have a large reserve of balls, there is then a safety problem, because of the large number of balls which end up strewn on the ground of the tennis court, and which can hinder the evolution of the players, even causing accidents (sprains, fractures) resulting from bad falls.

L'invention a pour but de permettre une récupération automatique de la quasi totalité des balles de tennis, au cours du déroulement du jeu, principalement pour éviter les accidents; elle découle de la constatation que la plupart des balles viennent heurter soit la paroi de fond du court, soit le filet de tennis lui-même.The invention aims to allow automatic recovery of almost all tennis balls, during the course of the game, mainly to avoid accidents; it stems from the observation that most of the balls hit either the back wall of the court or the tennis net itself.

Dans cet esprit, l'invention concerne donc une installation de récupération de balles, notamment pour un court de tennis, caractérisée en ce qu'elle comporte une pluralité de bandes souples, sensiblement parallèles, tendues,de préférence sensiblement horizontalement, en regard d'une surface verticale d'arrêt.In this spirit, the invention therefore relates to a ball recovery installation, in particular for a tennis court, characterized in that it comprises a plurality of flexible bands, substantially parallel, stretched, preferably substantially horizontally, opposite a vertical stop surface.

On entend plus particulièrement par "surface verticale d'arrêt" soit une paroi de fond du court de tennis, souvent matérialisée par un grillage, soit le filet de tennis lui-même.The term "vertical stopping surface" is understood to mean more particularly either a bottom wall of the tennis court, often materialized by a mesh, or the tennis net itself.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront mieux à la lumière de la description qui va suivre, de plusieurs modes de réalisation possibles d'une installation de récupération de balles conforme à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés, dans lesquels :

  • - la figure 1 est une vue partielle en perspective d'un court de tennis équipé d'une installation conforme à l'invention, tant au niveau du grillage du fond de court que du filet de tennis lui-même;
  • - la figure 2 est une vue schématique en coupe de l'installation agencée le long de la paroi de fond du court de tennis;
  • - la figure 3 est une vue partielle de face de la partie inférieure de l'installation de la figure 2;
  • - les figures 4a à 4c sont des vues de profil d'un système de regroupement des balles, dans différentes positions de fonctionnement successives;

The invention will be better understood and other advantages thereof will appear better in the light of the description which follows, of several possible embodiments of a bale recovery installation in accordance with its principle, given solely by way of example and made with reference to the accompanying drawings, in which:
  • - Figure 1 is a partial perspective view of a tennis court equipped with an installation according to the invention, both at the level of the base of the court and the tennis net itself;

En se reportant aux dessins, la figure 1 représente un court de tennis 11 comportant un filet 12 et entouré d'un grillage 13 à périmètre rectangulaire. Selon l'invention, au moins les deux surfaces verticales d'arrêt constituées par les parois grillagées de fond de court 14, parallèles au filet,sont en partie tapissées par une installation de récupération de balles comportant une pluralité de bandes souples 15 sensiblement parallèles. Ces bandes souples sont tendues horizontalement de façon à laisser subsister un espace 16 entre elles et la paroi grillagée 14. Comme le montre la figure 2, les bandes 14 sont disposées de façon à se chevaucher sur leur longueur, le bord inférieur de chaque bande étant engagé en retrait entre le bord supérieur de la bande inférieure voisine et la paroi grillagée 14. De plus, la partie supérieure de chaque bande retombe librement sur ladite bande elle-même. Les bandes sont tendues à leurs extrémités au moyen de crochets 18 fixés par exemple aux mailles des deux parois grillagées 19 perpendiculaires aux parois 14. Des oeillets (non représentés) fixés aux extrémités des bandes souples permettent leur fixation et leur mise en tension entre les deux parois grillagées 19, en éliminant les risques de déchirure. Les points d'accrochage des extrémités des bandes sont symbolisés en 20 sur la figure 2. C'est essentiellement la position de ces points d'accrochage le long des petits côtés d'une bande qui détermine la courbure de la partie supérieure libre de celle-ci. Comme le montrent les figures 2 et 3, la bande 15a la plus proche du sol est plus étroite que les autres, et son bord inférieur 22 est situé à une faible distance d au-dessus du sol, inférieure au diamètre d'une balle de tennis. En outre, la bande 15a comporte des échancrures verticales 23 facilitant la rentrée des balles roulant au sol à faible vitesse, dans l'espace 16. La hauteur des échancrures et la valeur de la distance d dépendent essentiellement de la souplesse et de la nature du matériau employé pour matérialiser les bandes 15. On peut, par exemple, utiliser de la toile plastifiée, des matériaux synthétiques souples, ou même de la toile de bâche. Les éléments d'une même bande peuvent être raccordés entre eux par couture ou même au moyen de boutons-pressions. Compte-tenu de la longueur des bandes et notamment lorsque le matériau employé est assez dense, il peut être nécessaire de soutenir lesdites bandes entre les deux groupes de crochets 18. Pour cela, on prévoit un câble 25 (figure 1) tendu parallèlement et au voisinage de la bande supérieure et les différentes bandes sont raccordées à ce câble au moyen de liaisons élastiques 26, en un ou plusieurs points le long de la paroi grillagée 14. On peut aussi faire en sorte que chaque bande souple soit soutenue par des crochets 27 rattachés à la paroi grillagée 14 (figure 8).Referring to the drawings, FIG. 1 represents a tennis court 11 comprising a net 12 and surrounded by a mesh 13 with a rectangular perimeter. According to the invention, at least the two vertical stop surfaces constituted by the mesh walls of the court bottom 14, parallel to the net, are partly upholstered by a bale recovery installation comprising a plurality of flexible bands 15 substantially parallel. These flexible bands are stretched horizontally so as to leave a space 16 between them and the mesh wall 14. As shown in FIG. 2, the bands 14 are arranged so as to overlap along their length, the lower edge of each band being engaged in withdrawal between the upper edge of the neighboring lower strip and the mesh wall 14. In addition, the upper part of each strip falls freely on said strip itself. The bands are stretched at their ends by means of hooks 18 fixed for example to the meshes of the two mesh walls 19 perpendicular to the walls 14. Eyelets (not shown) fixed to the ends of the flexible bands allow their fixing and their tensioning between the two mesh walls 19, eliminating the risk of tearing. The attachment points of the ends of the strips are symbolized at 20 in FIG. 2. It is essentially the position of these attachment points along the short sides of a strip which determines the curvature of the free upper part of that -this. As shown in Figures 2 and 3, the strip 15a closest to the ground is narrower than the others, and its lower edge 22 is located a short distance d above the ground, less than the diameter of a bullet. tennis. In addition, the strip 15a has vertical notches 23 facilitating the re-entry of the balls rolling on the ground at low speed, in space 16. The height of the notches and the value of the distance d depend essentially on the flexibility and the nature of the material used to materialize the strips 15. One can, for example, use plasticized canvas, materials soft synthetics, or even tarpaulin. The elements of the same strip can be connected together by sewing or even by means of press studs. Taking into account the length of the strips and in particular when the material used is dense enough, it may be necessary to support said strips between the two groups of hooks 18. For this, a cable 25 (FIG. 1) is provided stretched parallel and at in the vicinity of the upper strip and the various strips are connected to this cable by means of elastic connections 26, at one or more points along the screen wall 14. It is also possible to ensure that each flexible strip is supported by hooks 27 attached to the mesh wall 14 (Figure 8).

Selon une autre particularité de l'invention, un profilé de récupération 28,ayant essentiellement une section en L, est posé au sol le long de la paroi grillagée 14, au bas de l'espace 16 séparant cette dernière de l'agencement de bandes parallèles 15. De plus, des moyens de levage 29, visibles à la figure 5, permettent d'incliner le profilé par rapport à l'une de ses extrémités longitudinales pour rassembler les balles qui s'y sont accumulées vers un emplacement choisi. Selon l'exemple, on prévoit deux profilés 28 bout à bout le long de la paroi grillagée 14. Les extrémités opposées de ces profilés sont reliées à des câbles 30 associés à un système de poulies, de façon à pouvoir être tirées ensemble à partir d'un emplacement situé au milieu de la paroi 14. Une traction sur les câbles 30 permet d'incliner les deux profilés par rapport à leurs extrémités longitudinales voisines pour rassembler les balles vers le milieu de la paroi grillagée 14, c'est-à-dire précisément à l'emplacement où se trouve celui qui actionne les câbles 30. La figure 4 montre que l'extrémité de chaque câble 30 est reliée à un profilé 28 par deux tronçons de longueur inégale, le plus court étant fixé au bord de la partie horizontale du profilé, et le plus long étant fixé au bord de la partie verticale du même profilé. Ce mode de fixation permet de redresser le profilé vers l'arrière avant de le soulever, ce qui maintient les balles dans celui-ci.According to another feature of the invention, a recovery profile 28, having essentially an L-shaped section, is placed on the ground along the screen wall 14, at the bottom of the space 16 separating the latter from the arrangement of strips. parallel 15. In addition, lifting means 29, visible in FIG. 5, make it possible to tilt the profile relative to one of its longitudinal ends to collect the bales which have accumulated therein towards a chosen location. According to the example, two profiles 28 are provided end to end along the mesh wall 14. The opposite ends of these profiles are connected to cables 30 associated with a pulley system, so that they can be pulled together from 'a location in the middle of the wall 14. A pull on the cables 30 allows to tilt the two sections relative to their adjacent longitudinal ends to collect the balls towards the middle of the screen wall 14, that is to say tell precisely where the cable actuator 30 is located. FIG. 4 shows that the end of each cable 30 is connected to a profile 28 by two sections of unequal length, the shortest being fixed to the edge of the horizontal part of the profile, and the longest being fixed to the edge of the vertical part of the same profile. This method of fixing makes it possible to straighten the profile backwards before lifting it, which keeps the bales in it.

Le système de regroupement des balles qui vient d'être décrit peut faire l'objet de nombreuses variantes. Par exemple, le profilé 28a peut avoir une section en forme de goulotte (figure 6) pour que les balles ne puissent ressortir de l'espace 16. Pour les courts de tennis équipés d'origine des moyens de l'invention, on peut aussi prévoir de creuser une simple rigole 28b le long de chaque paroi grillagée 14 (figure 7), cette rigole étant de profondeur continuement variable, augmentant vers le milieu de la paroi 14, ou étant équipée du système de la figure 5.The bale grouping system which has just been described can be the subject of numerous variants. For example, the section 28a may have a section in the form of a chute (FIG. 6) so that the balls cannot come out of the space 16. For tennis courts originally equipped with the means of the invention, it is also possible plan to dig a simple channel 28b along each mesh wall 14 (FIG. 7), this channel being of continuously variable depth, increasing towards the middle of the wall 14, or being equipped with the system of FIG. 5.

Tout ce qui vient d'être décrit comme étant installé le long des parois de fond de court 14 est valable pour les deux autres parois 19 qui leur sont perpendiculaires, et aussi pour le filet 12, des bandes analogues aux bandes 15 pouvant être tendues de part et d'autre de celui-ci. Pour ce dernier cas, on utilisera de préférence un matériau transparent pour réaliser les bandes, en vue de conserver la visibilité au travers du filet de tennis. On pourra aussi découper les bandes dans du filet.All that has just been described as being installed along the end walls of the court 14 is valid for the two other walls 19 which are perpendicular to them, and also for the net 12, strips similar to the strips 15 which can be stretched by on either side of it. For the latter case, preferably a transparent material will be used to make the bands, in order to maintain visibility through the tennis net. We can also cut the strips in a net.

Avec l'agencement qui vient d'être décrit, toute balle projetée contre le grillage de fond de court 14 ou le filet de tennis lui-même traverse le rideau constitué par l'ensemble des balles et retombe au bas de l'espace laissé entre ce rideau et la surface verticale d'arrêt correspondante. Le moment venu, l'actionnement du système de regroupement des balles permet de les faire converger vers un point précis le long de ladite surface verticale d'arrêt.With the arrangement which has just been described, any ball projected against the bottom of the court 14 or the tennis net itself crosses the curtain formed by the set of balls and falls at the bottom of the space left between this curtain and the corresponding vertical stop surface. When the time comes, actuation of the bale grouping system allows them to converge at a specific point along said vertical stopping surface.

Bien entendu, l'invention n'est pas limitée au mode de réalisation des moyens décrits. De nombreuses autres variantes sont possibles. En particulier, si les bandes sont suffisamment étroites, voire filiformes, on peut envisager de les tendre verticalement. C'est dire que l'invention couvre tous les équivalents techniques des moyens mis en jeu, si ceux-ci le sont dans le cadre des revendications qui suivent.Of course, the invention is not limited to the embodiment of the means described. Many other variations are possible. In particular, if the strips are sufficiently narrow, or even threadlike, it is possible to consider tensioning them vertically. This means that the invention covers all the technical equivalents of the means involved, if these are within the scope of the claims which follow.
