Abstract

This blade makes it possible, by means of a fork-lift truck, to carry out various jobs, such as levelling, cleaning or snow removal. The actual blade (3) is connected in an articulated manner by means of a frame (4) to a support (2) which is equipped with sleeves (6) for introducing the forks of the fork-lift truck. The support (2) receives, or itself forms, a counterweight (5) which remains applied to the forks during the work and which thus improves the grip of the appliance on the ground. <IMAGE>

Description

La présente invention concerne une lame adaptable à l'avant d'un chariot élévateur classique, avec des fourches portées par un tablier pouvant être levé ou abaissé, cette lame pouvant avoir des usages divers tels que : nivellement, nettoyage, déneigement, etc...The present invention relates to a blade adaptable to the front of a conventional forklift, with forks carried by an apron that can be raised or lowered, this blade being able to have various uses such as: leveling, cleaning, snow removal, etc. .

La possibilité d'adaptation d'une lame sur un chariot élévateur est intéressante, par exemple pour pourvoir disposer d'un moyen de déneigement économique alors que l'achat d'un véritable chasse-neige représenterait un investissement trop coûteux. Ainsi les établissements industriels, les entrepôts ou les supermarchés, dans lesquels les chariots élévateurs sont utilisés de façon habituelle, ont une possibilité de déneigement de leurs cours, de leurs aires de stationnement pour véhicules, de leurs voies d'accès pour véhicules ou pour piétons ou de tout autre zone ou terrain situé à l'air libre.The possibility of adapting a blade on a forklift is interesting, for example to provide an economical means of snow removal while the purchase of a real snow plow would represent an investment too costly. Thus industrial establishments, warehouses or supermarkets, in which forklifts are used in the usual way, have the possibility of clearing snow from their yards, their parking areas for vehicles, their access routes for vehicles or pedestrians. or any other area or land located in the open air.

Les lames pour chariots élévateurs, actuellement connues, sont prévues habituellement pour être montées directement sur le tablier d'un chariot élévateur, les fourches étant retirées. Cette solution présente un inconvénient majeur ; en effet, les chariots élévateurs, surtout ceux n'ayant que deux roues motrices, ont une très mauvaise adhérence au sol à vide, de par leur conception et leur fonction habituelle, puisque la plus grande partie du poids du chariot élévateur se trouve à l'arrière afin d'équilibrer la charge prise par les fourches. De plus, le démontage et le remontage des fourches et des lames nécessitent du temps et de la main-d'oeuvre.The blades for forklifts, currently known, are usually intended to be mounted directly on the deck of a forklift, the forks being removed. This solution has a major drawback; indeed, forklifts, especially those with only two drive wheels, have very poor grip on the ground when empty, by their design and their usual function, since most of the weight of the forklift is rear to balance the load on the forks. In addition, the disassembly and reassembly of the forks and blades require time and labor.

L'invention vise à éliminer ces inconvénients, en fournissant une solution nouvelle améliorant de façon très sensible l'adhérence au sol de l'ensemble formé par le chariot et la lame, tout en facilitant la prise et la dépose de la lame et en permettant à cette lame de suivre les inégalités du terrain.The invention aims to eliminate these drawbacks, by providing a new solution which very significantly improves the adhesion to the ground of the assembly formed by the carriage and the blade, while facilitating the grip and removal of the blade and allowing to this blade to follow the unevenness of the ground.

A cet effet, l'invention a essentiellement pour objet une lame adaptable sur un chariot élévateur, comprenant en combinaison :
    - un support pourvu de fourreaux prévus pour l'introduction des fourches du chariot élévateur, ce support recevant ou constituant lui-même un contrepoids ;
    - une lame proprement dite, située en avant dudit support ; et
    - un châssis porte-lame, reliant la lame proprement dite au support précité.To this end, the invention essentially relates to a blade adaptable on a forklift, comprising in combination:
- A support provided with sleeves provided for the introduction of the forks of the forklift, this support receiving or constituting itself a counterweight;
- a blade proper, located in front of said support; and
- a blade holder frame, connecting the blade itself to the aforementioned support.

Une telle lame est adaptable de façon simple et rapide sur tout chariot élévateur, puisqu'elle est prise directement sur les fourches du chariot, sans transformation ni démontage. Elle possède en outre un avantage bien particulier, qui est l'amélioration de l'adhérence au sol de l'engin constitué par le chariot muni de cette lame, ceci grâce à la présence d'un contrepoids intégré, qui reste en charge sur les fourches pendant le travail de la lame.Such a blade can be quickly and easily adapted to any forklift, since it is taken directly on the forks of the truck, without transformation or disassembly. It also has a very particular advantage, which is the improvement in the grip of the machine constituted by the carriage fitted with this blade to the ground, this being due to the presence of an integrated counterweight, which remains loaded on the forks while working the blade.

De préférence, le châssis porte-lame est relié de façon articulée, notamment autour d'un axe horizontal, au support qui reçoit ou constitue lui-même le contrepoids ; ainsi, en course de travail, la lame proprement dite peut jouer en hauteur pour suivre les inégalités du terrain sur lequel elle est utilisée, tandis que le tablier du chariot est placé à une hauteur qui permet de conserver le contrepoids en charge sur les fourches.Preferably, the blade holder chassis is connected in an articulated manner, in particular around a horizontal axis, to the support which receives or itself constitutes the counterweight; thus, during the working stroke, the blade itself can play at height to follow the unevenness of the terrain on which it is used, while the carriage deck is placed at a height which allows the counterweight to be loaded on the forks.

Avantageusement, le châssis porte-lame est en outre relié au support par des moyens, tels qu'au moins une bielle ou une chaîne, qui limitent le débattement angulaire de l'articulation de ce châssis porte-lame par rapport audit support. Ainsi, lorsque l'on veut relever l'ensemble, il suffit de commander la levée du tablier du chariot élévateur : le support est alors levé par l'intermédiaire des fourches, et ce support entraîne lui-même la lame proprement dite vers le haut, par l'intermédiaire de la ou des bielles ou chaînes prenant en charge cette lame. Advantageously, the blade holder chassis is further connected to the support by means, such as at least one connecting rod or chain, which limit the angular movement of the articulation of this blade holder chassis relative to said support. So, when you want to raise the assembly, you just have to order the lifting of the forklift's deck: the support is then lifted by means of the forks, and this support itself drives the blade itself upwards , via the connecting rod (s) or chains supporting this blade.

De toute façon l'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de cette lame adaptable sur un chariot élévateur :

  • Figure 1 est une vue en perspective d'une lame adaptable sur un chariot élévateur, conforme à l'invention ;
  • Figure 2 est une vue en plan par dessus de la lame selon la figure 1 ;
  • Figure 3 est une vue de côté de la lame des figures 1 et 2, montrée en position de travail ;
  • Figure 4 est une vue de côté similaire à figure 3, mais représentant cette lame en position relevée ;
  • Figure 5 est une autre vue de côté, similaire aux deux précédentes, illustrant la prise de cette lame, ou sa dépose, par le chariot élévateur.
In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of this blade adaptable on a forklift:
  • Figure 1 is a perspective view of a blade adaptable to a forklift, according to the invention;
  • Figure 2 is a plan view from above of the blade according to Figure 1;
  • Figure 3 is a side view of the blade of Figures 1 and 2, shown in the working position;
  • Figure 4 is a side view similar to Figure 3, but showing this blade in the raised position;
  • Figure 5 is another side view, similar to the previous two, illustrating the grip of this blade, or its removal, by the forklift.

La lame, représentée au dessin, est destinée à être adaptée sur les fourches 1 d'un chariot élévateur, non représenté mais d'un type classique, ces fourches 1 étant portées par un tablier pouvant être levé ou abaissé. Les parties principales de la lame sont : un support 2, une lame proprement dite 3 et un châssis porte-lame 4 qui relie la lame proprement dite 3 au support 2.The blade, shown in the drawing, is intended to be adapted on the forks 1 of a forklift, not shown but of a conventional type, these forks 1 being carried by an apron which can be raised or lowered. The main parts of the blade are: a support 2, a blade proper 3 and a blade holder frame 4 which connects the blade proper 3 to the support 2.

Le support 2 possède un corps principal 5 qui constitue un contrepoids, soit par sa propre masse, soit en recevant une matière de lestage relativement pesante et peu coûteuse, telle que du sable. Au-dessous du corps principal 5, sont prévus deux fourreaux parallèles horizontaux 6 prévus pour l'introduction des fourches 1 du chariot élévateur. Le support 2 est encore muni, à sa partie inférieure et vers l'arrière, de deux pieds 7 prévus pour reposer sur le sol et de deux pattes 8 définissant un axe d'articulation horizontal 9, tandis qu'une chape 10 est prévue à l'avant du support 2 et en position centrale.The support 2 has a main body 5 which constitutes a counterweight, either by its own mass, or by receiving a relatively heavy and inexpensive ballasting material, such as sand. Below the main body 5, there are two horizontal parallel sleeves 6 provided for the introduction of the forks 1 of the forklift. The support 2 is also provided, at its lower part and towards the rear, with two feet 7 provided to rest on the ground and with two legs 8 defining a horizontal articulation axis 9, while a yoke 10 is provided at the front of the support 2 and in the central position.

Le châssis porte-lame 4 comprend, notamment, deux longerons 11 dont les extrémités antérieures sont solidarisées, et dont les extrémités postérieures sont articulées au support 2 suivant l'axe 9. La lame proprement dite 3 est portée par la partie avant du châssis 4, d'une manière qui sera précisée plus bas.The blade-holder chassis 4 comprises, in particular, two longitudinal members 11 whose front ends are joined, and whose rear ends are articulated to the support 2 along the axis 9. The blade itself 3 is carried by the front part of the chassis 4 , in a manner which will be specified below.

La partie avant du châssis porte-lame 4 est encore reliée au support 2 par une bielle 12, dont l'extrémité inférieure est articulée suivant un axe 13 à une chape 14 solidaire du châssis 4 et dont la partie supérieure possède une lumière 15 traversée par l'axe 16 de la chape 10 portée par le support 2.The front part of the blade-holder chassis 4 is also connected to the support 2 by a connecting rod 12, the lower end of which is articulated along an axis 13 to a yoke 14 secured to the chassis 4 and the upper part of which has a slot 15 through which the axis 16 of the yoke 10 carried by the support 2.

En position normale d'utilisation, comme le montre la figure 3, les fourches 1 du chariot élévateur sont engagées à fond dans les fourreaux respectifs 6 du support 2, et ces fourches 1 sont placées à une hauteur telle que la lame proprement dite 3 repose librement sur le sol 17, l'axe 16 de la chape 10 se situant vers le milieu de la lumière 15 de la bielle 12. Le contrepoids 5 du support 2 reste ainsi en charge sur les fourches, 1, pour compenser le poids du chariot élévateur concentré vers l'arrière de ce dernier, et la lame 3 peut jouer en hauteur dans les limites permises par la lumière 15 de la bielle 12, pour suivre les inégalités du sol 17, le châssis 4 pivotant alors autour de son axe d'articulation 9 sur le support 2.In the normal position of use, as shown in Figure 3, the forks 1 of the forklift are fully engaged in the respective sleeves 6 of the support 2, and these forks 1 are placed at a height such that the blade itself 3 rests freely on the ground 17, the axis 16 of the yoke 10 lying towards the middle of the lumen 15 of the connecting rod 12. The counterweight 5 of the support 2 thus remains loaded on the forks, 1, to compensate for the weight of the carriage riser concentrated towards the rear of the latter, and the blade 3 can play in height within the limits permitted by the lumen 15 of the connecting rod 12, to follow the unevenness of the ground 17, the chassis 4 then pivoting around its axis of articulation 9 on the support 2.

Comme le montre la figure 4, la lame 3 peut aussi être relevée, de manière à ne plus venir en contact avec le sol 17. A cet effet, les fourches 1 du chariot élévateur sont levées suffisamment haut, avec le tablier, pour que le châssis 4 et la lame 3 restent suspendus à la bielle 12, l'axe 16 de la chape 10 retenant cette bielle 12 par l'extrémité supérieure de la lumière 15. On a indiqué par α , sur cette figure 4, l'angle de débattement de l'articulation en 9 du châssis porte-lame 4.As shown in Figure 4, the blade 3 can also be raised, so as to no longer come into contact with the ground 17. For this purpose, the forks 1 of the forklift are raised high enough, with the deck, so that the chassis 4 and the blade 3 remain suspended from the connecting rod 12, the axis 16 of the yoke 10 retaining this connecting rod 12 by the upper end of the slot 15. It has been indicated by α, in this figure 4, the angle of movement of the articulation at 9 of the blade holder chassis 4 .

Pour la dépose de l'ensemble, il suffit d'abaisser le tablier avec les fourches 1. Comme le montre la figure 5, la lame 3 vient alors se poser sur le sol 17, et le support 2 vient lui-même reposer sur le sol par ses pieds 7. En reculant ensuite le chariot élévateur, les fourches 1 sont retirées des fourreaux 6 suivant la flèche 18. A l'inverse, pour la prise de la lame, les fourches 1 sont introduites dans les fourreaux 6 suivant la flèche 19, en faisant avancer le chariot élévateur, puis ces fourches 1 sont levées pour entraîner le support 2 vers le haut et le prendre ainsi en charge, avec son contrepoids 5.For the removal of the assembly, it suffices to lower the deck with the forks 1. As shown in FIG. 5, the blade 3 then comes to rest on the ground 17, and the support 2 itself comes to rest on the ground by its feet 7. Then moving the forklift back, the forks 1 are removed from the sleeves 6 along the arrow 18. Conversely, for gripping the blade, the forks 1 are introduced into the sleeves 6 along the arrow 19, by advancing the forklift, then these forks 1 are lifted to drive the support 2 upwards and thus take charge of it, with its counterweight 5.

Dans l'exemple considéré, la lame proprement dite 3 est liée à la partie avant du châssis porte-lame 4 par l'intermédiaire d'une plaque 20 et d'un axe d'articulation 21 sensiblement vertical, permettant d'orienter cette lame 3 soit hydrauliquement, soit manuellement, comme le montre notamment la figure 2 ; la lame 3 peut, en outre, être montée oscillante par rapport à la plaque 20 selon les flèches 22 (voir figure 1). Il est bien entendu que divers types de lames, et divers moyens d'orientation et de commande de ces lames, peuvent être utilisés avec le même système d'adaptation sur les fourches 1, selon les applications envisagées : nivellement, nettoyage, déneigement, etc...In the example considered, the blade itself 3 is linked to the front part of the blade-holder chassis 4 by means of a plate 20 and a substantially vertical hinge pin 21, making it possible to orient this blade 3 either hydraulically or manually, as shown in particular in Figure 2; the blade 3 can, moreover, be mounted to oscillate relative to the plate 20 according to the arrows 22 (see FIG. 1). It is understood that various types of blades, and various means of orientation and control of these blades, can be used with the same adaptation system on the forks 1, depending on the applications envisaged: leveling, cleaning, snow removal, etc. ...

Il va de soi, également, que les moyens décrits peuvent être remplacés par tous équivalents. Ainsi, la bielle 12 est remplaçable par une chaîne ou par tout autre dispositif procurant un degré de liberté ou une course nécessaire tout en assurant une retenue. L'articulation du châssis porte-lame 4 par rapport au support 2, illustrée sous la forme particulière d'un axe mécanique 9, peut aussi être de tout type ; en particulier, compte tenu de la faible valeur de l'angle de débattement α , cette articulation peut être réalisée simplement sous la forme d'un ou de plusieurs blocs flexibles, par exemple en caoutchouc.It goes without saying, also, that the means described can be replaced by any equivalent. Thus, the connecting rod 12 is replaceable by a chain or by any other device providing a degree of freedom or a necessary stroke while ensuring retention. The articulation of the blade-holder chassis 4 with respect to the support 2, illustrated in the particular form of a mechanical axis 9, can also be of any type; in particular, given the low value of the angle of movement α, this articulation can be produced simply in the form of one or more flexible blocks, for example made of rubber.
