Abstract

The apparatus for the manual removal of snow from various surfaces is composed of a front blade "A" and an arm "B" which pushes the blade. The blade is in the shape of stem the two branches of which (2a,2b) are connected by a cross member (8) on which the lower angled end of the arm is pivoted about a horizontal transverse axis. Each branch has a sloping U-shaped transverse section with the webs (4,5) inclined downwards. The lower web (5) is longer than the upper web and is extended by a return angled upwards to form a ground support flap. Projecting from the back of the cross member are two spaced tabs each passed through by a bore (10) constituting the pivot bearing.

Description

L'invention est relative à un appareil pour le déneigement manuel de surfaces diverses tels que chemin de circulation piétonne, aire de stationnement.The invention relates to an apparatus for manual snow removal from various surfaces such as pedestrian traffic, parking area.

Traditionnellement le déblayage de la neige s'effectue au moyen d'une pelle et de ce fait s'avère très fatigant.Traditionally snow removal is done with a shovel and therefore is very tiring.

Il existe cependant des appareils de déblaiement qui, par exemple comme décrit dans la demande de certificat d'utilité FR-A-2 692 296, sont composés d'un châssis sur roues portant une lame antérieure, articulée sur le châssis pour pouvoir être orientée en fonction de la résistance rencontrée.However, there are clearing machines which, for example as described in the request for utility certificate FR-A-2 692 296, are composed of a chassis on wheels carrying an anterior blade, articulated on the chassis to be able to be oriented according to resistance encountered.

Ces appareils sont onéreux et encombrants lorsqu'ils ne sont pas utilisés.These devices are expensive and bulky when not in use.

A cela, il faut ajouter que bien souvent le bord inférieur de leur lame se bloque sur les aspérités de la surface du sol en cours de déneigement, ce qui donne des à-coups et impose d'exécuter des manoeuvres consistant soit à surélever temporairement la lame, comme dans le document ci-dessus, soit à la retirer vers l'arrière pour échapper à l'obstacle.To this we must add that very often the edge bottom of their blade hangs on the rough edges of the ground surface being cleared of snow, which gives jerks and requires performing consistent maneuvers either to temporarily raise the blade, as in the above document, either remove it backwards to escape the obstacle.

En raison de ces inconvénients, l'application de ce type d'appareil est limitée, alors même que la demande est de plus en plus forte, en particulier dans les villes, par les commerçants et les collectivités.Because of these drawbacks, the application of this type of device is limited, even though demand is getting stronger, especially in cities, by traders and communities.

La présente invention a pour objet de fournir un appareil de déneigement qui remédie à ces inconvénients et soit simple, maniable, et peu onéreux tout en occupant un faible encombrement en position de rangement.The object of the present invention is to provide a snow clearing machine that overcomes these disadvantages and be simple, handy, and inexpensive while occupying a small footprint in storage position.

L'appareil selon l'invention est composé d'au moins une lame antérieure "A" et d'au moins un bras "B" permettant de pousser cette lame. Dans cet appareil de déneigement selon l'invention, la lame est en forme d'étrave, dont les deux branches, d'une part, sont reliées par une traverse, sur laquelle l'extrémité inférieure du bras de poussée est articulée autour d'un axe horizontal transversal, et, d'autre part, présentent, chacune et en section transversale, la forme d'un "U" couché à ailes inclinées vers le bas et dont l'aile inférieure est plus longue que celle supérieure et est prolongée par un retour coudé formant bavette d'appui au sol.The apparatus according to the invention is composed of at least at least one anterior blade "A" and at least one arm "B" allowing to push this blade. In this device of snow removal according to the invention, the blade is shaped bow, of which the two branches, on the one hand, are connected by a cross, on which the lower end of the push arm is articulated around a horizontal axis transverse, and, on the other hand, present, each and in cross section, the shape of a "U" lying on wings inclined downwards and whose lower wing is more longer than the upper one and is extended by a return angled forming a ground support flap.

Lorsque l'étrave est posée sur le sol, elle repose par sa bavette d'appui qui, formant un "V" comme l'étrave, donne une excellente stabilité à la lame, tout en empêchant qu'elle ait tendance à s'enfoncer, comme c'est le cas avec les lames portées par un châssis sur roues.When the bow is placed on the ground, it rests by its support flap which, forming a "V" like the stem, gives excellent stability to the blade, while preventing it from sinking, as it is the case with the blades carried by a chassis on wheels.

Lors d'une rencontre avec une aspérité, la bavette se soulève plus aisément qu'un bord franc, ce qui réduit les blocages de l'appareil et permet d'effectuer un déneigement continu sans avoir besoin de procéder à des mouvements de retrait vers l'arrière.During a meeting with an asperity, the bib lifts more easily than a straight edge, which reduces device locks and allows for a continuous snow removal without the need to carry out backward withdrawal movements.

En cas de blocage, la forme en "V" de l'étrave va naturellement déplacer celle-ci par rapport à l'aspérité, sans pour autant qu'il y ait arrêt d'avancement, donc d'à-coups fatigants et perturbant le déneigement.In case of blockage, the "V" shape of the bow will naturally move it in relation to the roughness, without stopping progress, therefore tiring jolts and disturbing snow removal.

D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé, représentant à titre d'exemple une forme d'exécution de l'appareil selon l'invention.Other features and benefits will emerge from the description which follows with reference to attached schematic drawing, showing by way of example an embodiment of the apparatus according to the invention.

Figure 1 est une vue en perspective de l'appareil.Figure 1 is a perspective view of the device.

Figure 2 en est une vue en élévation par l'arrière.Figure 2 is an elevational view through the back.

Figure 3 est une vue de face en élévation de l'appareil lorsqu'il est en position suspendue de rangement.Figure 3 is a front elevation view of the appliance when in the suspended position of storage.

Cet appareil est essentiellement constitué par une lame de déneigement "A" et par une barre de poussée "B". La lame de déneigement est en forme d'étrave 2, c'est-à-dire est composée de deux branches 2a et 2b formant un "V" convergent vers l'avant. Chacune des branches présente en section transversale la forme d'un "U" couché à ailes inégales, c'est-à-dire est composée d'une âme 3 sensiblement verticale et de deux ailes, respectivement supérieure 4 et inférieure 5, qui ne sont pas perpendiculaires à la lame, mais inclinées vers le bas par rapport à celle-ci, d'une valeur de l'ordre de 5 à 10°.This device essentially consists of a snow plow "A" and a push bar "B". The snow plow is in the shape of a bow 2, that is to say is composed of two branches 2a and 2b forming a "V" converging forward. Each of branches present in cross section the shape of a "U" lying with unequal wings, that is to say is composed a substantially vertical core 3 and two wings, respectively upper 4 and lower 5, which are not not perpendicular to the blade, but tilted downwards compared to this, with a value of the order of 5 to 10 °.

L'aile inférieure 5 est plus grande que l'aile supérieure 4 et est prolongée par un retour 6, coudé vers le haut par rapport à elle, de manière à être sensiblement perpendiculaire à la lame 3.The lower wing 5 is larger than the wing upper 4 and is extended by a return 6, angled towards the top with respect to it, so as to be substantially perpendicular to the blade 3.

La figure 1 montre que les différentes parties de chaque branche 2a, 2b sont liées par soudure en 7 de leurs extrémités antérieures. Les âmes 3 de l'étrave sont liées l'une à l'autre par une traverse transversale 8, qui, par exemple, est soudée sur le dos de ces lames. La traverse est solidaire de deux pattes postérieures 9, formées par exemple par découpage et pliage de la paroi arrière de cette traverse. Chaque patte 9 est traversée par un alésage circulaire 10, qui est aligné avec l'alésage de l'autre patte. Comme montré aux figures, ces deux alésages sont destinés à recevoir l'extrémité inférieure coudée 12 de la barre de poussée "B" qui, en position d'utilisation, est horizontale et transversale. Une goupille 13 assure le calage en translation de la partie coudée 12 par rapport aux pattes 9. L'extrémité supérieure de cette barre est coudée et contre-coudée pour former une poignée facilitant la transmission de l'effort à la barre de poussée.Figure 1 shows that the different parts of each branch 2a, 2b are linked by welding in 7 of their anterior extremities. The 3 souls of the bow are linked to each other by a transverse cross member 8, which, by example, is welded on the back of these blades. The crossing is integral with two hind legs 9, formed by example by cutting and folding the rear wall of this cross. Each leg 9 is crossed by a circular bore 10, which is aligned with the bore of the other leg. As shown in the figures, these two bores are intended to receive the bent lower end 12 push bar "B" which, in the use position, is horizontal and transverse. A pin 13 ensures the wedging in translation of the bent part 12 relative to legs 9. The upper end of this bar is angled and counter-angled to form a handle facilitating the transmission of the force to the push bar.

Les deux éléments de l'appareil peuvent être réalisés à partir de tôles et de tubes d'acier, mais il est avantageux qu'ils soient réalisés à partir de tôle et de tubes d'un alliage d'aluminium, afin de réduire leurs poids.Both parts of the device can be made from steel sheets and tubes, but it it is advantageous that they are made from sheet metal and aluminum alloy tubes to reduce their weight.

Lorsque l'appareil est utilisé, il est dans la position représentée à la figure 1, avec son étrave bien à plat sur le sol, par appui de sa bavette 6. Dans ces conditions, la bavette peut se soulever légèrement du sol lorsqu'elle rencontre une aspérité offrant une faible résistance et, en conséquence, ne pas être sans arrêt bloquée. Lorsqu'elle rencontre une aspérité ne pouvant pas passer sous elle, telle celle 11 représentée à la figure 1, la forme inclinée du côté correspondant de l'étrave crée une composante transversale de réaction qui chasse cette étrave transversalement, et lui permet de continuer d'avancer sans assurer un blocage complet.When the device is in use, it is in the position shown in Figure 1, with its stem well flat on the ground, by pressing its flap 6. In these conditions, the mud flap may lift slightly from the ground when it encounters an asperity offering a weak resistance and, therefore, not be constantly blocked. When it encounters an asperity that cannot pass under it, such as that 11 shown in the figure 1, the inclined shape of the corresponding side of the bow creates a transverse reaction component which drives out this bow transversely, and allows it to continue to advance without ensuring complete blocking.

Au fur et à mesure de l'avancement, la neige est chassée latéralement, de sorte que le déneigement laisse une surface déneigée ayant une largeur égale à la plus grande largeur de l'étrave. L'usage montre que cet appareil permet de réaliser sans grand effort un déneigement efficace dans une couche de neige allant jusqu'à trente à quarante centimètres.As you go along, the snow is driven sideways, so that snow removal leaves a snow-cleared surface with a width equal to the most large width of the bow. The practice shows that this device allows to realize without great effort a effective snow removal in a snow layer going up to thirty to forty centimeters.

La figure 3 montre que grâce à l'articulation du bras de poussée sur la lame "A", lorsque l'appareil est suspendu pour son rangement, l'étrave se met dans son prolongement en occupant ainsi un volume réduit.Figure 3 shows that thanks to the articulation of the push arm on blade "A", when the device is suspended for storage, the bow is placed in its extension thus occupying a reduced volume.
