Abstract

The blade forms a fixed V articulated on a support. The angle of opening of the V is defined along with the angle of orientation of the blade to the left or right to allow side evacuation of snow while retaining surface of the support on the blade. The blade has a fixed flap, and two lateral articulated flaps (6, 6`) retracted by a retraction mechanism that are supported against a frame supported by the support.

Description

La présente invention se rapporte à une lame en V fixe, ouvert vers l'avant, orientable par un système hydraulique ou par un dispositif mécanique. Sa conception, simple et fiable, reste très économique et est adaptable à tout véhicule ou engin pouvant supporter les efforts mécaniques de cette lame.The present invention relates to a fixed V-blade, open towards the front, adjustable by a hydraulic system or by a mechanical device. Her design, simple and reliable, remains very economical and is adaptable to any vehicle or machine that can withstand the mechanical forces of this blade.

De plus, cette lame en V intègre dans sa construction un mécanisme de sécurité par escamotage des volets, permettant ainsi le passage d'un obstacle sans provoquer de dommages sur la lame et l'engin sur lequel elle est fixée.In addition, this V blade incorporates in its construction a safety mechanism by retracting the shutters, allowing the passage of an obstacle without cause damage to the blade and the machine on which it is attached.

Par conséquent, l'enlèvement de la neige ou de tout autre matériau léger (sciure, grains, déchets...) reste une opération bon marché qui ne nécessite pas l'acquisition d'un chasse-neige ou d'un engin spécifique.Therefore, the removal of snow or other light material (sawdust, grain, waste ...) remains a cheap operation that does not require the acquisition of a snow plow or a specific machine.

L'équipement du véhicule avec la lame décrite dans notre invention permet le dégagement de la neige, sur les routes, sur les aires de stationnement, voies d'accès pour véhicules ou piétons ou toutes autres zones de terrains situés à l'air libre.The equipment of the vehicle with the blade described in our invention allows the clearing of snow, on roads, on parking areas, lanes access for vehicles or pedestrians or any other areas of land in the air free.

Le dispositif prévu permet de contenir efficacement la neige par la conformation de la lame en V, ouvert vers l'avant, dans sa position centrale. La neige peut donc être regroupée dans une zone de stockage.
Par ailleurs, un mécanisme d'orientation permet le fonctionnement par évacuation de la neige sur le côté droit ou le coté gauche comme le ferait une lame droite traditionnelle.The device provided can effectively contain the snow by shaping the V-shaped blade, open forwards, in its central position. The snow can therefore be grouped in a storage area.
In addition, an orientation mechanism allows operation by evacuation of snow on the right side or the left side as would a traditional straight blade.

L'art antérieur, par le brevet US6618960, décrit une lame traditionnelle, droite et orientable. Elle permet uniquement l'évacuation de la neige sur les cotés.
On connaít également le brevet US6574890 décrivant une lame concave. Cette lame de conception simple ne peut pas contenir efficacement la neige. De plus, elle ne dispose pas d'un dispositif d'orientation. Cette lame est destinée aux aires de stationnement.
Le brevet US5819444 expose une lame droite, équipée de volets latéraux mobiles. Cette lame met en oeuvre un mécanisme complexe. The prior art, patent US6618960, describes a traditional blade, straight and steerable. It only allows the evacuation of snow on the sides.
Also known is patent US6574890 describing a concave blade. This simple design blade can not effectively contain snow. In addition, it does not have an orientation device. This blade is intended for parking areas.
US 5819444 discloses a straight blade, equipped with movable side flaps. This blade implements a complex mechanism.

On connaít aussi le brevet WO99/61709, décrivant une lame en V ajustable. Cette conception est très complexe tant au niveau mécanique qu'au niveau des asservissements hydrauliques. Par conséquent, elle est plus fragile et par le déport à l'avant trop important, sa maniabilité est restreinte. Par ailleurs, la réalisation du basculement des volets est très complexe et de ce fait, d'un poids important. La réalisation des raccords et des articulations est très difficile à construire et donc onéreuse.We also know the patent WO99 / 61709, describing an adjustable V blade. This design is very complex both mechanically and at the level of hydraulic servo. Therefore, it is more fragile and by the offset too far forward, its maneuverability is restricted. Moreover, the flap tilting is very complex and therefore weighs important. Making joints and joints is very difficult to build and therefore expensive.

Toutes les descriptions de brevets, issues de l'état de l'art antérieur, font référence à des conceptions complexes et d'une faible capacité de retenue de neige.All patent descriptions, from the state of the prior art, refer to complex designs and low snow holding capacity.

L'objet de la présente invention est de proposer une alternative aux lames existantes par une conception efficace et économique rassemblant les avantages d'une lame droite et d'une lame en V.The object of the present invention is to propose an alternative to blades existing by an efficient and economical design bringing together the advantages a straight blade and a V blade.

Afin de faciliter la compréhension de l'invention, des modes de réalisation vont maintenant être décrits à l'aide des figures annexées dans lesquelles on trouve :

  • La figure 1 est une vue d'ensemble de dessus de la lame en V fixe avec dispositif d'orientation hydraulique, représentée en position centrale
  • La figure 2 est une vue d'ensemble de dessous de la lame en V fixe, représentée en position orientée à droite
  • La figure 3 est une vue d'ensemble arrière avec un volet gauche en cours d'escamotage d'un obstacle
    • In order to facilitate understanding of the invention, embodiments will now be described with the aid of the appended figures in which we find:
  • FIG. 1 is a top view of the fixed V-blade with hydraulic orientation device, shown in a central position
  • FIG. 2 is an overall view from below of the fixed V-shaped blade, represented in the right-oriented position.
  • FIG. 3 is a rear view with a left flap during the retraction of an obstacle

    • La figure 1 présente un ensemble poussé par un engin attelé à la plage de fixation (1), Le support (2) grâce à la forme en V de la lame est plus court que celui permis par les autres principes. Le point d'articulation (9), se trouvant ainsi très rapproché de l'engin pousseur, améliore la maniabilité et la motricité de l'engin. Ce support, solidaire de la plage de fixation (1), supporte les deux vérins d'orientation (4) et le point d'articulation du châssis dit fixe (3). Le châssis dit fixe (3) supporte deux volets latéraux articulés (6 et 6') et un volet central fixe (5).
    Les vérins (4) peuvent être actionnés, soit par une centrale autonome électrique ou thermique, soit par une prise hydraulique sur l'engin attelé.     Figure 1 shows an assembly pushed by a machine coupled to the fixing range (1), the support (2) with the V shape of the blade is shorter than that allowed by the other principles. The hinge point (9), thus being very close to the pusher gear, improves the maneuverability and traction of the machine. This support, secured to the fixing surface (1), supports the two orientation cylinders (4) and the hinge point of said fixed frame (3). The so-called fixed frame (3) supports two articulated lateral flaps (6 and 6 ') and a fixed central flap (5).
    The cylinders (4) can be actuated either by an autonomous electric or thermal power plant, or by a hydraulic catch on the coupled machine.

    La figure 2 représente l'un des avantages de la lame en V. Le contact au sol est équivalent à un rectangle imaginaire dont la longueur (L) est la distance entre les deux points extrêmes de la dite lame et la largeur (I) étant la hauteur du triangle isocèle, formé par le V en contact au sol. Cette surface d'appui équivalente empêche l'ensemble de pénétrer dans un sol meuble contrairement à une lame droite traditionnelle, qui, elle, ne demande qu'à descendre dans le sol.
    De même, l'angle d'ouverture du V fixe est défini de telle façon que l'orientation au maximum à droite ou à gauche combine à la fois les avantages d'une lame droite de par l'évacuation latérale de la neige et les avantages de la lame en V pour ce qui est de l'appui au sol.
    La figure 3, par sa vue arrière, représente le mécanisme d'escamotage des volets (6 et 6'). Ce mécanisme comporte un point d'articulation des volets (7) et des ressorts de rappels (8), solidaires du châssis dit fixe (3) d'une part, et des volets (6 et 6'), d'autre part. Ce mécanisme permet d'assurer une sécurité continue pour le basculement du ou des volets (6 et 6') lors de l'accrochage d'un obstacle et revient, à l'aide du ressort (8), en position repos. La continuité de la lame entre les deux volets (6 et 6') est assurée par un volet fixe (5). Celui-ci ne touche pas le sol afin de ne pas être détérioré par un éventuel obstacle.
    Dans une version très peu différente, seule la partie basse des volets latéraux serait escamotable et il n'y aurait alors pas de volet fixe central.    FIG. 2 represents one of the advantages of the V-shaped blade. The ground contact is equivalent to an imaginary rectangle whose length (L) is the distance between the two extreme points of said blade and the width (I) being the height of the isosceles triangle, formed by the V in contact with the ground. This equivalent bearing surface prevents the assembly from penetrating loose soil, unlike a traditional straight blade, which only needs to go down into the ground.
    Likewise, the opening angle of the fixed V is defined in such a way that the maximum orientation on the right or on the left combines both the advantages of a straight blade due to the lateral evacuation of the snow and the advantages of the V-blade when it comes to ground support.
    Figure 3, in its rear view, shows the mechanism of retraction of the flaps (6 and 6 '). This mechanism comprises a point of articulation of the flaps (7) and recoil springs (8), integral with said fixed frame (3) on the one hand, and flaps (6 and 6 '), on the other hand. This mechanism ensures continuous security for the tilting of the or flaps (6 and 6 ') during the attachment of an obstacle and returns, with the aid of the spring (8), in the rest position. The continuity of the blade between the two flaps (6 and 6 ') is provided by a fixed flap (5). It does not touch the ground so as not to be damaged by a possible obstacle.
    In a very little different version, only the lower part of the side flaps would be retractable and there would be no central fixed flap.

    Bien entendu, les modes de réalisation décrits ci-dessus ne présentent aucun caractère limitatif et pourront subir toutes modifications sans sortir du cadre de l'invention.Of course, the embodiments described above have no limiting nature and may be subject to any modifications without departing from the invention.
