Description

1. Domaine de l'invention 1. Field of the invention

Le domaine de l'invention est celui des engins de tonte du gazon ou de toute autre surface herbacée, et de leurs accessoires.The field of the invention is that of lawn mowing machines or any other herbaceous surface, and their accessories.

Plus précisément, l'invention concerne un dispositif permettant de basculer sur le côté une tondeuse autoportée, une tondeuse thermique ou une tondeuse électrique, ou tout autre engin analogue, pour procéder au nettoyage des lames de coupe et/ou au débourrage du carter de protection, à des opérations d'entretien, et par exemple à l'affutage des lames, ou à des réparations.More specifically, the invention relates to a device for tilting a lawn mower, a mower or an electric lawn mower, or any other similar machine, for the cleaning of the cutting blades and / or the breaking of the protective casing. , to maintenance operations, and for example sharpening blades, or repairs.

2. Etat de la technique 2. State of the art

Il est connu d'utiliser un appareil de levage pour accéder sous une tondeuse afin de nettoyer les lames de coupe ou de les remplacer.It is known to use a hoist to access under a mower to clean the cutting blades or replace them.

Le plus souvent, ces appareils présentent une structure porteuse basculante permettant de soulever au moins deux roues de la tondeuse. Deux types de structures porteuses basculantes connues sont très classiquement mises en oeuvre : les structures à bras pivotant unique et les structures en parallélogramme, constituées de deux bras pivotants reliés par une table horizontale.Most often, these devices have a tilting carrier structure for lifting at least two wheels of the mower. Two types of known tilting load bearing structures are very conventionally used: single pivot arm structures and parallelogram structures, consisting of two pivoting arms connected by a horizontal table.

On connaît ainsi, par exemple, des appareils munis d'un levier, prolongé par un bras porteur, que l'on actionne et bloque en position relevée à l'aide d'une barre d'extension.Thus known, for example, devices with a lever, extended by a support arm, which is actuated and blocked in the raised position with the aid of an extension bar.

Pour relever le bras pivotant, on a également proposé de mettre en oeuvre une béquille de relevage formée par une vis sans fin, qui traverse un écrou à l'extrémité du bras et est actionnée par une manivelle, ou encore un treuil à actionnement mécanique.To raise the pivot arm, it has also been proposed to implement a lifting stand formed by a worm, which passes through a nut at the end of the arm and is actuated by a crank, or a winch mechanically actuated.

Un inconvénient de ces techniques connues est qu'elles requièrent de la force physique pour lever ou basculer la tondeuse, notamment si le poids de la tondeuse est important. Elles ne conviennent donc pas à des usagers frêles ou affaiblis, et/ou dans le cas où la tondeuse est lourde. Elles sont plus généralement d'un usage pénible, et/ou sont peu ergonomiques, ce qui n'est pas satisfaisant.A disadvantage of these known techniques is that they require physical force to lift or tilt the mower, especially if the weight of the mower is important. They are therefore not suitable for frail or weak users, and / or in the case where the mower is heavy. They are generally of a heavy use, and / or are not very ergonomic, which is not satisfactory.

Pour limiter les efforts de l'usager, on a pensé à actionner l'appareil de levage à l'aide d'un vérin.To limit the efforts of the user, it was thought to operate the hoist with a jack.

Le document FR-A-2 873 107 décrit un tel exemple de technique mettant en oeuvre un vérin souple ou un vérin à tige de piston rigide exerçant une poussée sous le bras pivotant du châssis pour assurer son basculement.The document FR-A-2,873,107 describes such an example of technique using a flexible jack or a rigid piston rod jack exerting a thrust under the pivoting arm of the frame to ensure its tilting.

Cette technique présente cependant de nombreux inconvénients.This technique, however, has many disadvantages.

Elle offre en effet un accès limité au dessous de la tondeuse, du fait de la présence d'un vérin. Par ailleurs, un autre inconvénient de cette technique réside dans son encombrement résiduel en hauteur après que le bras pivotant, venant en butée sur le corps du vérin, ait été rabattu.It offers limited access to the underside of the mower, due to the presence of a cylinder. Furthermore, another disadvantage of this technique lies in its residual height space after the pivoting arm, abutting on the cylinder body, has been folded.

Un autre inconvénient de cette technique est qu'elle nécessite la mise en oeuvre de vérins spécifiques, et par exemple un vérin à tige de grande dimension ou un vérin à tige télescopique.Another disadvantage of this technique is that it requires the implementation of specific cylinders, and for example a large rod cylinder or a telescopic rod cylinder.

Encore un inconvénient de cette technique est que l'usager est susceptible d'actionner par mégarde la baisse du vérin lorsqu'il intervient sous la tondeuse, ce qui n'est pas acceptable en termes de sécurité.Another disadvantage of this technique is that the user is likely to inadvertently actuate the decline of the cylinder when it comes under the mower, which is not acceptable in terms of safety.

On connait également du document US-B1-6 345 807 un appareil de levage d'une tondeuse autoportée équipé d'un vérin permettant de faire pivoter une plateforme sur laquelle on monte la tondeuse afin de la basculer vers l'arrière. Dans le document US-B1-6 345 807 , la plateforme se range à l'intérieur élément de châssis reposant sur le sol, lorsqu'elle est abaissée.We also know of the document US-B1-6,345,807 a hoist of a riding mower equipped with a jack for pivoting a platform on which the mower is mounted to tilt backwards. In the document US-B1-6,345,807 , the platform is stowed inside chassis member resting on the ground, when lowered.

3. Objectifs de l'invention 3. Objectives of the invention

L'invention a donc notamment pour objectif de pallier les inconvénients de l'art antérieur cités ci-dessus.The invention therefore particularly aims to overcome the disadvantages of the prior art mentioned above.

Plus précisément l'invention a pour objectif de fournir un dispositif de basculement proposant une assistance efficace au levage.More specifically, the invention aims to provide a tilting device offering effective assistance to lifting.

Un objectif de l'invention est également de fournir une telle technique qui dégage un accès important sous la tondeuse.An object of the invention is also to provide such a technique which releases a significant access under the mower.

Un autre objectif de l'invention est de fournir une telle technique qui soit simple à mettre en oeuvre, et d'un coût de fabrication réduit.Another object of the invention is to provide such a technique that is simple to implement, and a reduced manufacturing cost.

Un objectif de l'invention est également de proposer une telle technique qui soit compacte, et aisée à stocker.An object of the invention is also to provide such a technique which is compact and easy to store.

Encore un objectif de l'invention est de fournir une telle technique qui soit fiable, sûr et sans danger pour l'utilisateur.Yet another object of the invention is to provide such a technique which is reliable, safe and safe for the user.

4. Exposé de l'invention 4. Presentation of the invention

Ces objectifs, ainsi que d'autres qui apparaitrons par la suite sont atteints à l'aide d'un dispositif de basculement d'un engin de tonte d'herbe, notamment une tondeuse autoportée, comprenant un élément de châssis fixe, destiné à reposer sur le sol, et un élément de châssis apte à recevoir au moins une roue dudit engin, mobile autour d'un axe porté par ledit élément de châssis fixe, entre une position de rangement dans lequel ledit élément de châssis mobile s'étend sensiblement dans le plan formé par ledit élément de châssis fixe, et au moins une position relevée dans lequel ledit élément de châssis mobile est écarté dudit élément de châssis fixe.These objectives, as well as others that will appear thereafter are achieved by means of a tipping device of a grass mowing machine, including a riding mower, comprising a fixed frame member, intended to rest on the ground, and a frame member adapted to receive at least one wheel of said machine, movable about an axis carried by said fixed frame member, between a storage position in which said movable frame member extends substantially in the plane formed by said fixed frame member, and at least one raised position wherein said movable frame member is spaced from said fixed frame member.

Selon l'invention, un tel dispositif comprend un vérin, présentant un corps solidaire dudit élément de châssis fixe et une tige mobile par rapport audit corps, solidaire dudit élément de châssis mobile, monté de sorte à s'étendre sensiblement à l'extérieur de la zone délimitée par lesdits éléments de châssis fixe et mobile dans ladite position relevée.According to the invention, such a device comprises a jack, having a body secured to said fixed frame member and a rod movable relative to said body, integral with said movable frame member, mounted so as to extend substantially outside the the area delimited by said fixed and mobile frame members in said raised position.

Ainsi, de façon inédite, l'invention propose de mettre en oeuvre un vérin pour faciliter le basculement de l'engin sur le côté, qui n'empiète pas sur la zone utile à l'utilisateur pour intervenir sous l'engin. Par ailleurs, on a un accès convenable à la commande du vérin.Thus, in a novel way, the invention proposes to implement a jack to facilitate the tilting of the machine on the side, which does not impinge on the area useful to the user to intervene under the machine. In addition, there is adequate access to the cylinder control.

Selon un mode de réalisation particulièrement avantageux de l'invention, ledit élément de châssis mobile est configuré pour s'emboiter dans ledit élément de châssis fixe, dans ladite position de rangement.According to a particularly advantageous embodiment of the invention, said movable frame member is configured to fit into said fixed frame member, in said storage position.

Ainsi, le dispositif forme un ensemble compact dans la position de rangement, ce qui facilite son stockage. Par ailleurs, la hauteur réduite du châssis dans la position de rangement, encore appelée position basse, facilite la montée des roues de l'engin sur le châssis mobile.Thus, the device forms a compact assembly in the storage position, which facilitates its storage. Furthermore, the reduced height of the chassis in the storage position, also called low position, facilitates the rise of the wheels of the machine on the mobile frame.

Selon un aspect particulier de l'invention, ledit axe est monté sensiblement au-dessus du plan formé par ledit élément de châssis fixe.According to a particular aspect of the invention, said axis is mounted substantially above the plane formed by said fixed frame member.

Ainsi, on libère astucieusement un espace sous axe, et par conséquent sensiblement au dessous de l'élément de châssis mobile, dans lequel on peut monter le vérin, de façon à ce qu'il pousse sur la face inférieure de l'élément de châssis mobile.Thus, cleverly free space under axis, and therefore substantially below the movable frame member, in which one can mounting the jack, so that it pushes on the underside of the movable frame member.

Dans au moins un mode de réalisation avantageux de l'invention, ledit élément de châssis mobile présente une forme d'équerre en « L », dont l'angle est tronqué.In at least one advantageous embodiment of the invention, said movable frame member has an "L" square shape, whose angle is truncated.

Ainsi, on peut faire reposer l'élément de châssis à plat sur le sol. Selon l'invention, ledit vérin est solidarisé à proximité dudit axe auxdits éléments de châssis fixe et mobile.Thus, the chassis member can be rested flat on the ground. According to the invention, said jack is secured near said axis to said fixed and movable frame members.

Ainsi, on peut assurer un angle de relevage important, et par exemple de 50°, en utilisant un vérin ordinaire, et notamment sans qu'il soit nécessaire de prévoir un vérin à tige télescopique.Thus, it is possible to provide a large lifting angle, for example 50 °, using an ordinary jack, and in particular without the need to provide a telescopic rod cylinder.

Selon un aspect avantageux de l'invention, un tel dispositif présente au moins une béquille escamotable solidaire dudit élément de châssis mobile et prenant appui sur ledit élément de châssis fixe pour verrouiller le élément de châssis mobile dans au moins une desdites positions relevées.According to an advantageous aspect of the invention, such a device has at least one retractable stand secured to said movable frame member and bearing on said fixed frame member to lock the movable frame member in at least one of said raised positions.

Ainsi, on peut intervenir en toute sécurité, sans risque qu'un accident, provoqué par un abaissement brutal de l'élément de châssis mobile, survienne.Thus, one can intervene safely, without risk that an accident, caused by a sudden lowering of the movable frame member, occurs.

De façon avantageuse, ledit élément de châssis mobile comprend un cadre configuré pour recevoir ladite ou lesdites roues, et une butée s'étendant sensiblement perpendiculairement audit cadre.Advantageously, said movable frame member comprises a frame configured to receive said wheel or wheels, and a stop extending substantially perpendicularly to said frame.

L'engin est ainsi maintenu efficacement lors du levage, grâce au cadre qui forme un berceau pour les roues et à la butée sur laquelle on peut appuyer le côté le plus bas de l'engin. En outre, un tel dispositif est adapté ou du moins adaptable, par exemple à l'aide de rallonges, à différentes tailles d'engins.The machine is thus effectively maintained during lifting, thanks to the frame which forms a cradle for the wheels and the stop on which one can press the lower side of the machine. In addition, such a device is adapted or at least adaptable, for example by means of extensions, to different sizes of gear.

Préférentiellement, ledit vérin est actionné par une pédale ou un levier.Preferably, said cylinder is actuated by a pedal or a lever.

L'utilisateur n'a ainsi pas à se baisser pour actionner le vérin, et il conserve une ou les mains libres pour retenir l'engin, le cas échéant.The user does not have to stoop to operate the cylinder, and he keeps one or both hands free to hold the machine, if any.

Selon un aspect avantageux de l'invention, ledit vérin est à simple effet.According to an advantageous aspect of the invention, said jack is single acting.

Ainsi, le coût du dispositif reste faible.Thus, the cost of the device remains low.

Selon l'invention, ledit vérin appartient au groupe comprenant au moins :

  • vérin hydraulique ;
  • vérin pneumatique ;
  • vérin électrique.
According to the invention, said jack belongs to the group comprising at least:
  • hydraulic cylinder ;
  • pneumatic jack ;
  • electric cylinder.

Comme déjà indiqué, le principe de l'invention repose notamment sur le montage d'un vérin de relevage de l'élément de châssis pivotant d'un dispositif « lève-tondeuse » à l'extérieur de la zone délimitée par les éléments de châssis fixe et mobile d'un dispositif « lève-tondeuse », de façon à gêner le moins possible l'utilisateur lorsqu'il intervient sous la tondeuse.As already indicated, the principle of the invention is based in particular on the mounting of a lift cylinder of the pivoting frame member of a device "lawn mower" outside the area delimited by the frame members fixed and movable device "lawn mower", so as to interfere as little as possible when the user intervenes under the mower.

6.2 Exemple de mode de réalisation de l'invention 6.2 Example of embodiment of the invention

On a illustré sur la figure 1, un premier mode de réalisation d'un dispositif de basculement 10 selon l'invention d'une tondeuse autoportée 11, dans une vue en perspective.We illustrated on the figure 1 , a first embodiment of a tilting device 10 according to the invention of a riding mower 11, in a perspective view.

Ce dispositif 10 comprend un élément de châssis fixe 12, reposant sur le sol portant un axe 13, surélevé par rapport au sol, par exemple de dix-sept centimètres dans ce mode de réalisation de l'invention, autour duquel est articulé en rotation un élément de châssis mobile 14, représenté dans une position relevée sur la figure 1.This device 10 comprises a fixed frame element 12, resting on the ground carrying an axis 13, elevated with respect to the ground, for example seventeen centimeters in this embodiment of the invention, around which is articulated in rotation a movable frame member 14, shown in a raised position on the figure 1 .

Comme on peut le voir sur la figure 1, la tondeuse autoportée 11, dont les roues arrière 111 reposent sur une portion du cadre 141 de l'élément de châssis mobile 14, est basculée sur le côté dans cette position relevée. On a ainsi un large accès sous la tondeuse, pour nettoyer les lames de coupe et débourrer le carter de coupe 112, par exemple.As can be seen on the figure 1 , the riding mower 11, whose rear wheels 111 rest on a portion of the frame 141 of the movable frame member 14, is tilted to the side in this raised position. There is thus a wide access under the mower, to clean the cutting blades and to break the cutting deck 112, for example.

Par ailleurs, on remarque qu'aucune pièce du dispositif 10 n'empiète de façon significative sur la zone 15 délimitée par les éléments de châssis fixe 12 et mobile 14. Cette spécificité avantageuse de l'invention permet, par exemple, de s'allonger sans difficulté sous la tondeuse, de poser ses outils au sol, de faire cheminer un tuyau d'arrosage ou la lance d'un nettoyeur haute pression sous la tondeuse, sans rencontrer d'obstacle, et plus généralement de ne pas être gêné dans ses mouvements.Moreover, it is noted that no part of the device 10 impinges significantly on the area 15 delimited by the fixed frame members 12 and mobile 14. This advantageous feature of the invention allows, for example, to lie down without difficulty under the mower, to put his tools on the ground, to run a garden hose or the lance of a pressure washer under the mower, without encountering any obstacle, and more generally not to be embarrassed in his movements.

L'élément de châssis fixe 12 comprend un cadre métallique 121 mécano-soudé dans ce mode de réalisation de l'invention, définissant un plan pour l'élément 12. Ce cadre 121 se prolongeant verticalement par deux pattes 21 soutenant le palier tubulaire 22, dans lequel est logé l'axe 13, tel qu'il apparait plus clairement sur la figure 2, vu de l'arrière. Il convient de noter que la longueur du cadre 121 doit être suffisante pour assurer la stabilité du dispositif 10.The fixed frame member 12 comprises a welded metal frame 121 in this embodiment of the invention, defining a plane for the element 12. This frame 121 extending vertically by two tabs 21 supporting the tubular bearing 22, in which is located the axis 13, as it appears more clearly on the figure 2 , seen from the back. It should be noted that the length of the frame 121 must be sufficient to ensure the stability of the device 10.

L'élément de châssis mobile 14 présente une forme d'équerre en « L ». Il est obtenu par soudure, ou par tout autre procédé d'assemblage approprié connu, d'un cadre 141 formant un berceau pour les roues arrière de la tondeuse, avec deux cornières 23 métalliques, orientées sensiblement perpendiculairement au cadre 141 et qui forment une butée latérale supportant la roue la plus basse.The movable frame member 14 has an "L" square shape. It is obtained by welding, or by any other suitable method known assembly, a frame 141 forming a cradle for the rear wheels of the mower, with two metal angles 23, oriented substantially perpendicular to the frame 141 and which form a stop side supporting the lowest wheel.

L'articulation de l'élément de châssis mobile 14 sur l'élément de châssis fixe 12 est réalisée en boulonnant les extrémités de l'axe 13 sur les cornières 23, qui forment une fourche pour l'axe 13.The articulation of the movable frame member 14 on the fixed frame member 12 is achieved by bolting the ends of the pin 13 to the brackets 23, which form a fork for the pin 13.

Dans ce mode de réalisation de l'invention le cadre 141 est à ossature tubulaire, afin de ne pas endommager les roues lorsqu'on fait rouler la tondeuse sur celui-ci. Par ailleurs, la longueur du cadre 141 a été déterminée en fonction de l'empâtement des roues arrière.In this embodiment of the invention the frame 141 is tubular frame, so as not to damage the wheels when rolling the mower on it. Furthermore, the length of the frame 141 was determined according to the impasto of the rear wheels.

Un vérin à simple effet 24 actionnable à l'aide d'une pédale 25 est monté entre l'élément de châssis fixe 12 et l'élément de châssis mobile 14, en passant sous l'axe 13. Le corps 241 de ce vérin est fixé à l'élément de châssis fixe, à proximité de l'axe 13, et l'extrémité de la tige 242 de piston de ce vérin est monté pivotante autour d'un axe 210 logé dans une fourche s'étendant à partir du cadre 141. On comprend donc à la simple vue de cette figure 2, que la tige de ce vérin exerce une poussée sur la face inférieure de l'élément de châssis mobile 14, ce qui permet de le faire pivoter vers le haut ou vers le bas par un simple actionnement du vérin 24 (dont l'effet est de faire avancer ou respectivement reculer la tige 242 par rapport au corps 241 du vérin).A single-acting cylinder 24 actuable by means of a pedal 25 is mounted between the fixed frame member 12 and the movable frame member 14, passing under the axis 13. The body 241 of this jack is attached to the fixed frame member, near the axis 13, and the end of the piston rod 242 of this jack is pivotally mounted about an axis 210 housed in a fork extending from the frame 141. We can therefore understand at the mere sight of this figure 2 , that the rod of this jack exerts a thrust on the lower face of the movable frame member 14, which allows it to be pivoted upwards or downwards by a simple actuation of the jack 24 (the effect of which is to advance or respectively back the rod 242 relative to the body 241 of the cylinder).

Deux béquilles latérales 27 ont été prévues pour verrouiller l'élément de châssis mobile 14 dans cette position relevée maximale, dans laquelle le cadre 141 de l'élément de châssis mobile 14 est écarté d'un angle d'environ 49° par rapport au cadre 121 (voir la figure 3, qui est une vue de côté du dispositif 10), et empêcher un abaissement brutal de celui-ci. Une première extrémité de ces béquilles est montée pivotante sur l'une ou l'autre des cornières 23. Leur deuxième extrémité prend appui sur la traverse arrière 26 du cadre 121, ce qui assure le verrouillage. Cette deuxième extrémité présente dans ce mode de réalisation de l'invention une encoche biseautée afin de renforcer l'appui sur la traverse 121, obtenue à partir d'un profilé de section carré.Two side stands 27 have been provided to lock the movable frame member 14 in this maximum raised position, in which the frame 141 of the movable frame member 14 is spaced at an angle of about 49 ° from the frame. 121 (see the figure 3 which is a side view of the device 10), and prevent a sharp lowering thereof. A first end of these stands is pivotally mounted on one or the other angles 23. Their second end is supported on the rear cross member 26 of the frame 121, which ensures the locking. This second end presents in this embodiment of the invention a notched notch to strengthen the support on the cross 121, obtained from a section of square section.

Ces béquilles sont en outre reliées par un arceau de sécurité formant poignée 28, afin de pouvoir facilement escamoter les béquilles 27 avant de commencer à abaisser l'élément de châssis mobile 14 à partir de la position relevée maximale.These crutches are further connected by a rollbar forming a handle 28, in order to easily retract the crutches 27 before begin lowering the movable frame member 14 from the maximum raised position.

On a également prévu des roulettes 29, montées sur l'élément de châssis fixe 12 pour pouvoir déplacer aisément le dispositif 10 sur le sol.There are also provided rollers 29, mounted on the fixed frame member 12 to easily move the device 10 on the ground.

Sur les figures 4 et 5, le dispositif 10 est représenté de côté dans sa position de rangement (position basse), suite au basculement dans le sens de la flèche 41 de l'élément de châssis mobile 14 jusqu'au niveau du sol, obtenu en relâchant le vérin. On constate sur la coupe verticale de la figure 4, que la face inférieure du cadre 141 de l'élément de châssis mobile repose complètement sur le sol, après qu'il soit venu s'emboiter, du fait de sa largeur, dans le cadre 121 de l'élément de châssis fixe (voir le dispositif en vue de dessus figure 5). Le cadre 141 ne dépassant pas au dessus du cadre 121, le dispositif 10 présente ainsi un aspect particulièrement compact et plat dans la position de rangement, appréciable en considération du stockage du dispositif et facilitant la montée des roues de l'engin sur le cadre 141.On the Figures 4 and 5 , the device 10 is shown from the side in its storage position (low position), following the tilting in the direction of the arrow 41 of the movable frame member 14 to the ground level, obtained by releasing the cylinder. We see on the vertical section of the figure 4 , that the lower face of the frame 141 of the movable frame member rests completely on the ground, after it has come to fit, because of its width, in the frame 121 of the fixed frame member (see the device in top view figure 5 ). The frame 141 does not protrude above the frame 121, the device 10 thus has a particularly compact and flat appearance in the storage position, appreciable in view of the storage of the device and facilitating the rise of the wheels of the machine on the frame 141 .
