Description

RAMASSE BALLES DE TENNIS TENNIS BALL PICKUP
La présente invention concerne un appareil pour le ramassage des balles de tennis.The present invention relates to an apparatus for collecting tennis balls.
Les appareils existant actuellement sont de trois types : . type manuel dont font partie les paniers ramasse balles qui exigent de la part du ramasseur le positionnement de celui-ci au-dessus de la balle puis une pression sur celle-ci afin de la faire pénétrer dans, le panier, par le fond, à travers un volet anti-retour s ' ouvrant vers l'intérieur du panier ou à travers des mailles légèrement inférieures dans leur plus petite dimension au diamètre de la balle.There are three types of devices currently in existence:. manual type of which the baskets collect bales which require from the picker the positioning of this one above the ball then a pressure on it in order to make it penetrate into the basket, from the bottom, to through a non-return flap opening towards the inside of the basket or through meshes slightly smaller in their smallest dimension than the diameter of the bale.
. type mécanique à volet de ramassage dont le principe est un chariot poussé par l'utilisateur muni à son avant d'un court plan incliné, à l'avant duquel se situe un volet que l'utilisateur rabat sur les balles arrivées au pied du plan incliné afin de les faire pénétrer dans un panier situé immédiatement derrière le dispositif et au niveau de celui-ci . type mécanique à transporteur à bande ou à palle dont le principe est un chariot ou un véhicule moto- propulsé prolongé à son avant d'un système de collecte des balles qui permet de guider celles-ci vers la bande ou les pâlies du transporteur. Le premier type d'appareil cité oblige le ramasseur à exercer une pression sur le panier et à le soulever au- dessus de quasiment chaque balle, ce qui au bout d'un certain temps devient fatigant.. mechanical type with pickup flap, the principle of which is a trolley pushed by the user, equipped at its front with a short inclined plane, at the front of which is a flap that the user folds over the bales arriving at the bottom of the plane tilted to allow them to enter a basket located immediately behind and at the level of the device. mechanical type with belt or paddle conveyor, the principle of which is a trolley or a propelled vehicle extended at its front by a bale collection system which makes it possible to guide them to the conveyor's belt or blades. The first type of apparatus mentioned obliges the collector to exert pressure on the basket and to lift it above almost each ball, which after a certain time becomes tiring.
Le deuxième type d'appareil cité oblige l'utilisateur, en Plus de la poussée du chariot, à manoeuvrer au moment opportun la manette du volet rabatable, ce qui présente l'inconvénient d'avoir à surveiller ce moment' et ce qui amoindrit donc la fiabilité et l'efficacité du ramassage.The second type of device mentioned obliges the user, in addition to the thrust of the carriage, to maneuver at the appropriate moment the lever of the folding shutter, which has the disadvantage of having to monitor this moment 'and which therefore reduces reliability and efficiency of collection.
Le troisième type d'appareil cité est de réalisation complexe donc onéreuse et est encombrant. D'autre part, les problèmes de réglage de l'intervale séparant la bande duThe third type of device mentioned is of complex construction therefore expensive and is bulky. On the other hand, the problems of adjusting the interval separating the band from the
LE DE REMPLACEM NT transporteur du plan incliné sur lequel roulent les balles rendent les appareils utilisant ce procédé peu fiables et potentiellement inefficaces.THE REPLACEM NT carrier of the inclined plane on which the balls roll make the devices using this process unreliable and potentially ineffective.
L'objectif de la présente invention est donc de présenter un appareil :The objective of the present invention is therefore to present an apparatus:
. de réalisation simple c'est-à-dire utilisant la force de la poussée de l'utilisateur pour mettre en oeuvre, à partir des roues, le mécanisme d'un transporteur par un entrainement direct. . fiable dans le ramassage des balles c'est-à-dire évitant le blocage de celles-ci dans le mécanisme mais évitant aussi que les balles puissent se soustraire au ramassage . efficace c'est-à-dire permettant le ramassage et la remontée d'éventuellement plusieurs balles de front dans un panier situé à hauteur d'homme et permettant les marches arrières de l'appareil sans pour autant relâcher les balles éventuellement engagées dans le transporteur.. simple realization that is to say, using the force of the push of the user to implement, from the wheels, the mechanism of a conveyor by a direct drive. . reliable in the collection of bales, that is to say preventing them from blocking in the mechanism but also preventing the bales from being able to evade collection. efficient, that is to say allowing the collection and ascent of possibly several bales in front in a basket located at breast height and allowing the rear steps of the device without releasing any bales engaged in the conveyor .
. de faible encombrement c'est-à-dire pliable après utilisation de façon à pouvoir être installé dans le coffre d'une voiture de tourisme.. compact, that is to say foldable after use so that it can be installed in the trunk of a passenger car.
. léger c'est-à-dire pouvant être transporté à la main à l'aide d'une poignée, une fois l'appareil replié.. light that is to say, can be carried by hand using a handle, once the device folded.
L'invention a donc pour objet un appareil destiné à ramasser les balles de tennis comportant un châssis plan rectangulaire muni de deux joues latérales d'égale longueur fixées perpendiculairement au plan.The invention therefore relates to an apparatus for picking up tennis balls comprising a rectangular flat frame provided with two side cheeks of equal length fixed perpendicular to the plane.
Ce ch ssis est caractérisé en ce qu'il est muni d'une béq.uille escamotable fixée au milieu de la largeur et au tiers de la longueur environ sur la face du plan opposée à celle de fixation des joues. La béquille est terminée par une roue pivotante, quand la béquille est non escamotée et qu'elle repose sur sa roue, elle incline le châssis vers ce que l'on désignera comme l'avant de l'appareil. La roue pivo- tante rend l'appareil maniable, le caractère escamotable deThis ch ssis is characterized in that it is provided with a retractable béq.uille fixed in the middle of the width and about a third of the length on the face of the plane opposite to that for fixing the cheeks. The stand is terminated by a swivel wheel, when the stand is not retracted and it rests on its wheel, it inclines the chassis towards what will be designated as the front of the device. The swivel wheel makes the device handy, the retractable nature of
FEUILLE DE REMPLACEMENT la béquille permet de diminuer fortement l'encombrement pendant une opération de transport manuel ou pour permet¬ tre un rangement facile dans un coffre de voiture.REPLACEMENT SHEET the stand makes it possible to greatly reduce the size during a manual transport operation or to allow easy storage in a car trunk.
Le châssis est caractérisé en ce qu'il comporte à l'avant deux roues, une fixée à l'extérieur de chaque joue. Les roues ont une bande de roulement, cerclée d'un pneuma¬ tique ou d'une matière souple ne détériorant pas la surface sur laquelle est utilisé l'appareil. Lorsque l'appareil est en service, le châssis affleure le sol.The chassis is characterized in that it comprises two wheels at the front, one fixed to the outside of each cheek. The wheels have a tread, surrounded by a pneuma¬ tick or a flexible material that does not damage the surface on which the device is used. When the device is in use, the chassis is flush with the ground.
Le châssis est, en outre, caractérisé en ce qu'il est muni d'un transporteur à barres occupant toute la largeur de l'entre-joue et dont le mouvement qui permet le captage, puis la remontée des balles est obtenu par le déplacement de l'appareil par transmission directe de rotation des roues au transporteur. Le transporteur est constitué de deux courroies cran¬ tées sans fin supportées chacune par deux poulies crantées . Pour chaque courroie, une poulie est fixée sur l'axe de la roue avant, l'autre est fixée sur un axe transversal aux joues à l'extrémité supérieure du châssis celui-ci étant considéré, reposant sur ses roues. Les barres de captage et de remontée sont fixées sur les courroies parallèlement à l'axe des roues. Les diamètres des roues et des poulies sont calculés pour que les barres au cours du captage et de la remontée des balles au-dessus du sol et du châssis incliné soient à une distance sensiblement égale au rayon de la balle de tennis.The chassis is, furthermore, characterized in that it is provided with a bar conveyor occupying the entire width of the crotch and whose movement which allows the capture, then the ascent of the balls is obtained by displacement of the device by direct transmission of wheel rotation to the transporter. The conveyor consists of two endless cran¬ belts each supported by two notched pulleys. For each belt, a pulley is fixed on the axis of the front wheel, the other is fixed on an axis transverse to the cheeks at the upper end of the chassis, this being considered, resting on its wheels. The collecting and lifting bars are fixed on the belts parallel to the axis of the wheels. The diameters of the wheels and pulleys are calculated so that the bars during the collection and ascent of the balls above the ground and the inclined frame are at a distance substantially equal to the radius of the tennis ball.
Les barres portent des galets montés sur paliers. La longueur des galets est au maximum égale au diamètre d'une balle de tennis. Les barres ainsi définies ne peuvent coincer les balles entre le sol et elles-mêmes au moment du captage puisque par le jeu des galets elles sont soit captées et ramassées, soit franchement rejetées.The bars carry rollers mounted on bearings. The length of the pebbles is at most equal to the diameter of a tennis ball. The bars thus defined cannot wedge the balls between the ground and themselves at the time of collection since, by the play of the rollers, they are either captured and picked up, or frankly rejected.
C'est une des poulies crantées montée sur l'axe d'une des roues qui donne le mouvement aux barres de remontée desIt is one of the notched pulleys mounted on the axis of one of the wheels which gives movement to the lifting bars of the
FEUILLE DE REMPLACEMENT balles, de plus cette poulie est équipée d'une roue libre afin d'empêcher la rotation en marche arrière des barres de remontée lors des mouvements de recul de l'appareil notamment en arrivant contre les grillages ou le filet du court. L'autre poulie avant est montée folle sur l'axe de l'autre roue avant.REPLACEMENT SHEET balls, moreover this pulley is equipped with a freewheel in order to prevent the rotation in reverse of the ascent bars during backward movements of the apparatus in particular when arriving against the fences or the court net. The other front pulley is mounted idly on the axle of the other front wheel.
Les deux autres poulies arrières sont clavetées sur un seul et même axe.The other two rear pulleys are keyed on a single axis.
Le châssis est, en outre, caractérisé par la présence d'un dispositif évitant la fuite des balles devant les barres de ramassage. Ce dispositif est constitué d'une série de tubes montés sur un axe au devant des roues avant. Ces tubes d'un diamètre intérieur largement supérieur à l'axe s'escamotent sous la poussée des balles. Si la balle est repoussée par la barre de ramassage, elle vient buter contre les tubes lesquels ne peuvent pas pivoter dans l'autre sens vu la présence d'un deuxième axe qui est extérieur aux tubes et contre lequel ils butent.The chassis is further characterized by the presence of a device preventing the escape of bales in front of the pick-up bars. This device consists of a series of tubes mounted on an axle in front of the front wheels. These tubes with an internal diameter much greater than the axis retract under the thrust of the balls. If the ball is pushed back by the pickup bar, it abuts against the tubes which cannot pivot in the other direction given the presence of a second axis which is external to the tubes and against which they abut.
Le châssis est de plus caractérisé par la présence d'un panier collecteur des balles accroché à sa partie supé¬ rieure et maintenu verticalement par appui sur la béquille décrite plus haut. Les balles remontées par les barres de ramassage y sont déversées lorsqu'elles quittent le contact du châssis incliné. Le châssis est caractérisé en ce qu'il est couvert d'un capot qui cache le mécanisme de remontée. Le capot est pourvu de plusieurs lumières permettant l'accrochage de plusieurs paniers supplémentaires de réserve de balles.The chassis is further characterized by the presence of a bale collecting basket attached to its upper part and held vertically by pressing on the stand described above. The bales brought up by the pick-up bars are dumped there when they leave the contact of the inclined chassis. The chassis is characterized in that it is covered with a cover which hides the ascent mechanism. The hood is provided with several lights allowing the attachment of several additional bale reserve baskets.
Le châssis est caractérisé en ce que ses joues sont chacune équipées d'une poignée située à l'aplomb du centre de gravité de l'appareil et permettant un transport à la main aisé une fois la béquille escamotée.The chassis is characterized in that its cheeks are each equipped with a handle located directly above the center of gravity of the device and allowing easy transport by hand once the stand is retracted.
Le châssis est enfin caractérisé par la présence sur ses joues, d'une barre de poussée située au-dessus du panier collecteur permettant la manoeuvre de l'appareil.The chassis is finally characterized by the presence on its cheeks, of a push bar located above the collecting basket allowing the operation of the device.

FIG. 7 represents a front view, the upper cover with its hooking lights for the reserve baskets.
Le châssis incliné 6 (figure 1 et 4) est muni de joues latérales 24 qui supportent à leurs parties infé- rieures chacune une roue qui permettent le déplacemeent de l'appareil. La roue 11 permet, outre le déplacement de l'appareil, la mise en mouvement des barres 7 de remontée et de ramassage des balles 18. L'autre roue 13 est folle sur son axe pour jouer le rôle de différentiel et éviter la dislocation de l'appareil au cours de la manoeuvre rapide en virage.The inclined chassis 6 (FIGS. 1 and 4) is provided with lateral cheeks 24 which support at their lower parts each a wheel which allows the movement of the device. The wheel 11 allows, in addition to the movement of the device, the setting in motion of the bars 7 for lifting and collecting the balls 18. The other wheel 13 is mad on its axis to play the role of differential and avoid the dislocation of the aircraft during rapid cornering.
L'appareil en fonctionnement est maintenu en posi¬ tion stable par une béquille 20 escamotable terminée à sa partie inférieure par une roue escamotable 16. Cette roue 16 permet un guidage efficace de l'appareil.The device in operation is kept in a stable position by a retractable stand 20 terminated at its lower part by a retractable wheel 16. This wheel 16 allows effective guidance of the device.
La partie supérieure de la béquille 20 est en forme de Té fig. 5. Elle est fixée au châssis 6 par deux chapes 15. Le maintien en position en service ou escamoté de cette béquille 20 est assuré par un ensemble vis écrou 21 fig. 5 dont l'écran est muni d'une poignée de manoeuvre 22.The upper part of the stand 20 is T-shaped fig. 5. It is fixed to the chassis 6 by two yokes 15. Maintaining in position in service or retracted this stand 20 is ensured by a screw nut 21 assembly fig. 5, the screen of which is provided with an operating handle 22.

The movement of the carriage makes it possible to meet the tennis balls and bring them to the p.ièd of the inclined chassis 6. The balls in this position are picked up by the bars 7 fixed on two endless toothed belts 8, which are supported by four toothed pulleys.
La poulie crantée 9 équipée d'une roue libre est asservie à la roue 11. C'est elle qui met en mouvement les barres de remontée et de ramassage des balles.The toothed pulley 9 fitted with a free wheel is slaved to the wheel 11. It is this which sets in motion the ascent and ball collecting bars.
La roue libre de la partie crantée 9 permet le débray¬ age* de la rotation des barres lors des déplacements en marche arrière de l'appareil . Ce dispositif évite aux balles enga¬ gées sur le châssis incliné 6 de redescendre au cours des marches arrières de l'appareil nécessaires lorsque l'on arrive contre les grillages ou le filet du court de tennis au cours du ramassage des balles.The freewheel of the notched part 9 allows the declutching * of the rotation of the bars during reverse movements of the device. This device prevents the balls engaged on the inclined frame 6 from falling back down during the rear steps of the apparatus necessary when one arrives against the fences or the net of the tennis court during the collection of the balls.
Les poulies crantées supérieures 5 sont solidaires de l'axe 27 monté sur palier à billes fixées sur les joues 24. La quatrième poulie crantée 14 est montée folle sur l'axe de la roue 13. Les poulies crantées 9 et 14 sont pro¬ tégées par les déflecteurs 17 qui prolongent les joues 24 dans leur partie inférieure .The upper toothed pulleys 5 are integral with the axis 27 mounted on a ball bearing fixed on the cheeks 24. The fourth toothed pulley 14 is mounted idly on the axis of the wheel 13. The toothed pulleys 9 and 14 are protected by the deflectors 17 which extend the cheeks 24 in their lower part.
De façon à éviter que les balles 18 se dérobent au ramassage, l'avant de l'appareil est équipé d'une rangée de volets anti-retour10. Sous l'effet de la poussée de l'appa¬ reil, les volets montés sur l'axe 28 s'escamotent au contact des balles 18 puis retombent s 'opposant ainsi à la fuite des balles étant donné que ces volets ne peuvent s'escamoter que dans le sens inverse à la marche avant de l'appareil, les volets 10 butant contre l'axe 29.In order to prevent the balls 18 from getting picked up, the front of the device is equipped with a row of non-return flaps10. Under the effect of the thrust of the device, the flaps mounted on the axis 28 retract in contact with the balls 18 and then fall down, thus opposing the escape of the balls since these flaps cannot retract that in the opposite direction to the forward operation of the device, the flaps 10 abutting against the axis 29.
Les balles situées entre les volets anti-retour 10 et le bas du ch ssis incliné sont prises en charge par les barres 7 de ramassage et de remontée.The bales located between the non-return flaps 10 and the bottom of the inclined frame are supported by the pickup and ascent bars 7.

The bars 7 are fitted with rollers 19 intended to considerably improve the collection of bales and to prevent them from being pinched between the bars and the blocking ground. so the mechanism. The bars 7 occupying almost the entire width of the crotch 24 of the ch ssis and therefore allowing the pickup and ascent of several balls per bar.
L'appareil pouvant être réalisé avec des largeurs variables, le nombre de balles ramassées simultanément est lui-même variable. Par ailleurs, le nombre de barres 7 est calculé de façon à permettre un ramassage maximum pour une distance minimum parcourue avec l'appareil sans pour autant gêner par leur nombre l'efficacité du captage des balles au pied du châssis incliné 6.As the device can be made with variable widths, the number of bales picked up simultaneously is itself variable. Furthermore, the number of bars 7 is calculated so as to allow maximum pick-up for a minimum distance traveled with the device without, however, hampering the number of bales at the foot of the inclined chassis 6 by their number.
Les balles prises en charge par les barres sont remontées au sommet du ch ssis incliné et déversées dans le panier collecteur 4 placé suffisamment haut pour éviter au joueur de se baisser au moment où ayant ramassé ses balles il recommence à les utiliser.The balls supported by the bars are raised to the top of the inclined frame and dumped into the collecting basket 4 placed high enough to prevent the player from bending down when he has picked up his balls and begins to use them again.
Le panier 4 est fixé à l'aide de crochets 3 engagés au sommet du châssis incliné.The basket 4 is fixed using hooks 3 engaged at the top of the inclined frame.
Si le joueur le juge utile, il aura la possibilité d'accrocher plusieurs paniers de réserve sur le capot avant 25 lequel comporte des lumières 26 dans lesquelles sont engagés les crochets 3 des paniers supplémentaires 2. Une barre de poussée 1 fixée sur les joues 24 permet la manoeuvre de l'appareil.If the player deems it useful, he will have the possibility of hanging several reserve baskets on the front cover 25 which includes lights 26 in which the hooks 3 of the additional baskets are engaged 2. A push bar 1 fixed on the cheeks 24 allows the operation of the device.
Deux poignées 23 fixées sur chacune des joues laté- raies et situées à l'aplomb du centre de gravité de l'appareil permettent son transport aisé à la main, une fois la béquille escamotée.Two handles 23 fixed to each of the side cheeks and situated directly above the center of gravity of the device allow its easy transport by hand, once the stand is retracted.
