Description
La présente invention concerne un racleur de déneigement en métal pour déblayer des rues ou places fortement verglacées, lequel est disposé élastiquement au bord inférieur de la lame d'un chasse-neige. The present invention relates to a metal snow removal scraper for clearing heavily icy streets or squares, which is disposed elastically at the lower edge of the blade of a snow plow.
De tels racleurs de déneigement sont déja connus de l'état de la technique. Par exemple, dans le brevet français 1 243 526 est décrit un racleur en métal, qui est fixé, au moyen d'une baguette en caoutchouc, au bord inférieur de la lame d'un chasse-neige. De cette façon, on obtient une jonction élastique entre le racleur et la lame.Cette proposition est désavantageuse, cependant, par le fait que lors d'une forte sollicitation, par exemple pour un déblaiement de rues fortement verglacées, la baguette en caoutchouc se détruit rapidement et le racleur en métal se détache de la lame
Dans le brevet français nO 1 255 480 est révélé un racleur ou une baguette en combinaison, qui, selon l'encombrement de la rue, peut déblayer au moyen d'une baguette ou d'un racleur en caoutchouc ou bien d'un racleur en métal pouvant être replié sur la baguette en caoutchouc. Dans ce but, la baguette ou le racleur en métal est maintenu, sur des charnières, par des boulons filetés, qui sont introduits dans des manchons rembourrés de caoutchouc.Cette proposition présente un inconvénient par l'effet défavorable de levier de la baguette en métal qui, sur une rue ou route rugueuse peut conduire à une séparation des boulons filetés et des manchons. De plus, un tel mode de construction est assez coûteux et sujet à perturbations. Par ailleurs, le montage lache du racleur en métal sur la baguette en caoutchouc est une source importante de bruit lorsque l'on déblaie des rues fortement verglacées.Such snow removal scrapers are already known from the state of the art. For example, in French patent 1,243,526 describes a metal scraper, which is fixed, by means of a rubber rod, to the lower edge of the blade of a snow plow. In this way, an elastic junction is obtained between the scraper and the blade. This proposal is disadvantageous, however, by the fact that during a heavy load, for example for clearing heavily icy streets, the rubber strip is destroyed quickly and the metal scraper comes off the blade
In French Patent No. 1,255,480 is disclosed a combination scraper or rod, which, depending on the size of the street, can be cleared by means of a rubber rod or scraper or a metal can be folded over the rubber strip. For this purpose, the metal rod or scraper is held, on hinges, by threaded bolts, which are introduced into rubber-padded sleeves. This proposal has a disadvantage due to the unfavorable lever effect of the metal rod. which on a rough street or road can lead to separation of threaded bolts and sleeves. In addition, such a construction method is quite expensive and subject to disturbances. Furthermore, the loose mounting of the metal scraper on the rubber strip is a significant source of noise when clearing heavily icy streets.
La présente invention a par conséquent pour tâche de configurer un racleur de déneigement du type ci-dessus de façon qu'il soit résistant au cisaillement et amorti contre les bruits, et peu sujet aux perturbations malgré une construction simple. The present invention therefore has the task of configuring a snow removal scraper of the above type so that it is resistant to shearing and damped against noise, and little subject to disturbance despite a simple construction.
Cette tâche est résolue par la présente invention par le fait que le racleur en métal est vulcanisé par son bord supérieur, dans une couche de caoutchouc protégée de chaque côté par des plaques en métal. This task is solved by the present invention by the fact that the metal scraper is vulcanized by its upper edge, in a layer of rubber protected on each side by metal plates.
De cette façon, le racleur en métal peut éviter les irrégularités. Par la vulcanisetion dans une couche de caoutchouc entre deux plaques en métal, on obtient un déblaiement agressif sur des rues et places fortement verglacées. Mais il n'y a pas les conditions de levier ci-dessus décrites, car la force du levier du racleur métallique est absorbée par la couche en caoutchouc et les plaques en métal qui l'entourent. In this way, the metal scraper can avoid irregularities. By vulcanizing in a layer of rubber between two metal plates, aggressive clearance is obtained on heavily icy streets and squares. But there are not the lever conditions described above, since the force of the lever of the metal scraper is absorbed by the rubber layer and the metal plates which surround it.
Etant donné que, pour rendre la meilleure possible la durée de vie d'un tel racleur en métal, il faut avantageusement utiliser des alliages d'acier très dur, qui cepen dantpr0entent l'inconvénient d'être cassants , il est avantageux que l'ensemble du racleur se compose de plusieurs pièces courtes disposées les unes à côté des autres sur la lame du chasse-neige. Les pièces d'un tel racleur sont mobiles indépendamment les unes des autres et ont quelque peu l'effet d'un balai et les pièces détruites du racleur peuvent facilement être échangées. Dans le cas d'un racleur en une pièce, des fissures peuvent se former par suite de la fragilité de l'acier, qui s'étendent sur toute la longueur du racleur. Cela a pour suite que tout le racleur doit être échangé. Since, to make the life of such a metal scraper as good as possible, it is advantageous to use very hard steel alloys, which however have the drawback of being brittle, it is advantageous for the The scraper assembly is made up of several short pieces arranged next to each other on the plow blade. The parts of such a scraper are movable independently of each other and have somewhat the effect of a brush and the destroyed parts of the scraper can easily be replaced. In the case of a one-piece scraper, cracks may form due to the brittleness of the steel, which extend over the entire length of the scraper. As a result, the entire scraper must be replaced.
Pour qu'à l'échange des pièces détruites, les diffe- rences de longueur du racleur métallique dues à l'usure puissent être compensées, il est avantageux que les perçages prévus pour la réception des boulons filetés de fixation présentent, dans le racleur de déneigement, la forme de trous allongés. To compensate for the exchange of destroyed parts, the differences in length of the metal scraper due to wear can be compensated for, it is advantageous that the holes provided for receiving the threaded fixing bolts have, in the scraper snow removal, the shape of elongated holes.
L'invention sera miteux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence au dessin schématique illustrant un mode de réalisation de l'invention, et dans lequel
La figure unique montre, en vue en perspective, une coupe faite à travers un racleur de déneigement.The invention will be seedy, and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the schematic drawing illustrating an embodiment of the invention, and in which
The single figure shows, in perspective view, a section made through a snow removal scraper.
Sur une lame désignée par le chiffre de référence 1 est disposé, à son bord inférieur 2, à l'aide de boulons filetés 3 et d'écrous 4, un racleur de déneigement 5. Ce racleur de déneigement 5 se compose d'une baguette 6 en métal, de préférence en un alliage d'acier très dur, qui est vulcanisée, par son bord supérieur 7 quelque peu rétreci, dans une couche en caoutchouc 8. La couche en caoutchouc 8 est, de son côté, vulcanisée entre deux plaques en métal 9 et 10 parallèles l'une à l'autre. Les boulons filetés 3 sont introduits dans l'ensemble métal-caoutchouc-metal par des perçages 11 ayant la forme de trous allongés, lequel ensemble est de cette façon relié au bord inférieur 2 de la lame 1 en butée. Comme, dans le cas d'un acier très cassant de la baguette 6, le danger de formation de fissures n'est pas à exclure, des pièces courtes du racleur 5 sont disposées les unes à côté des autres sur la lame 1. De cette façon, seules des pièces isolées de tout le racleur sont endommagées, qui peuvent être rapidement changées à faible prix. Comme les perçages 11 prévus pour la réception des boulons filetés 3 ont la forme de trous allongés, on peut compenser, lors de l'échange des pièces détruites, les différences de longueur dues à l'usure dans la baguette métallique. On a blade designated by the reference numeral 1 is disposed, at its lower edge 2, using threaded bolts 3 and nuts 4, a snow removal scraper 5. This snow removal scraper 5 consists of a strip 6 made of metal, preferably of a very hard steel alloy, which is vulcanized, by its slightly shrunk upper edge 7, in a rubber layer 8. The rubber layer 8 is, for its part, vulcanized between two plates metal 9 and 10 parallel to each other. The threaded bolts 3 are introduced into the metal-rubber-metal assembly by holes 11 having the form of elongated holes, which assembly is in this way connected to the lower edge 2 of the blade 1 in abutment. As, in the case of a very brittle steel of the rod 6, the danger of cracking is not to be excluded, short pieces of the scraper 5 are arranged next to each other on the blade 1. From this this way, only parts isolated from the entire scraper are damaged, which can be quickly changed at low cost. As the holes 11 provided for receiving the threaded bolts 3 have the form of elongated holes, it is possible to compensate, during the exchange of the destroyed parts, for the differences in length due to wear in the metal rod.
