Abstract

An apparatus for the removal of snow which can be rapidly and easily fitted onto a private car. It consists of a slanting blade (1), with three use positions, and of a set of links (7) (8) (9) (10) (11) and (3) (19) (20), ensuring that it is in constant contact with the ground, and a shock-resistant safety device (11) (25). The low weight of the assembly (29) (30) (31) enables it to be picked up manually. An adaptor framework (12) enables it to be used on all vehicles. Intensive use requires a vehicle with integral motor unit.

Description

La présente invention concerne un dispositif de déneigement adapté sur un quelconque véhicule. Toutefois, pour des conditions d'utilisation intensive, un véhicule à motricité intégrale est conseillé.The present invention relates to a snow removal device suitable for any vehicle. However, for conditions of intensive use, a vehicle with all-wheel drive is recommended.

Il existe des dispositifs de montage d'appareils de déneigement qui permettent de compenser des dévers latéraux et longitudinaux, mais la mobilité du soc de déneigement est constituée de systèmes surajoutés formant des blocs indépendants, ce qui a pour conséquence l'augmentation du nombre de pièces, donc du poids et des coûts de fabrication. Ces systèmes conventionnels nécessitent l'adjonction d'appareillages généralement hydauliques imposant par là une mise en oeuvre importante lors des montages et démontages. De plus, le véhicule doit être équipé d'une source d'énergie disponible afin de pouvoir recevoir cet équipement, ce qui entraîne une vocation unique quant à l'utilisation du véhicule.There are mounting devices for snow clearing machines that compensate for lateral and longitudinal cant, but the mobility of the plow share consists of superimposed systems forming independent blocks, which results in an increase in the number of parts. , therefore weight and manufacturing costs. These conventional systems require the addition of generally hydaulic equipment, thereby imposing significant implementation during assembly and disassembly. In addition, the vehicle must be equipped with an available energy source in order to receive this equipment, which creates a unique vocation for the use of the vehicle.

Le dispositif présenté supprime ces inconvénients. En effet, la conception de la lame valide l'homogénéité du dispositif dans son ensemble qui génère simultanément son fonctionnement et sa sécurité propre, selon un système mécanique isostatique. La conception de ce dispositif permet ainsi de limiter le nombre de pièces mécaniques, donc le poids. Elle évite le recours à un appareillage complexe généralement hydraulique.The device presented eliminates these drawbacks. Indeed, the design of the blade validates the homogeneity of the device as a whole which simultaneously generates its operation and its own safety, according to an isostatic mechanical system. The design of this device thus makes it possible to limit the number of mechanical parts, and therefore the weight. It avoids the need for complex, generally hydraulic, equipment.

Le dispositif présenté permet d'une part de garder, quelles que soient les conditions de déclivité, un contact permanent avec le sol, et d'autre part, de ne pas créer une contrainte de torsion sur la structure du véhicule. La conception du dispositif permet un amortissement des chocs éventuels reçus par la lame. Cette même conception préserve la motricité du véhicule puisque repoussant davantage la neige côté évacuation, quel que soit le côté choisi pour l'orientation de la lame, oblique gauche ou oblique droit, ou encore position frontale.The device presented makes it possible on the one hand to keep, whatever the slope conditions, a permanent contact with the ground, and on the other hand, not to create a torsional stress on the structure of the vehicle. The design of the device allows absorption of any shocks received by the blade. This same design preserves the traction of the vehicle since it repels snow more on the evacuation side, whatever the side chosen for the orientation of the blade, left oblique or right oblique, or even frontal position.

Un cadre intermédiaire de fixation permet un montage et démontage rapide et donc une utilisation ponctuelle de l'ensemble. Ce cadre permet de plus une adaptation sur tous les véhicules sans les défigurer, tout en les laissant conformes à. la législation.An intermediate fixing frame allows rapid assembly and disassembly and therefore punctual use of the assembly. This framework also allows adaptation on all vehicles without disfiguring them, while leaving them conform to. the legislation.

La position haute de la lame est obtenue par un relevage manuel que permet la légèreté de l'ensemble.The high position of the blade is obtained by manual lifting which allows the lightness of the whole.
