Abstract

The rear door 6 pivots about a horizontal spindle 7 supported by the upper ends of the rear uprights 5 of the side walls 4, at least at the height of the upper edge of the side walls. The spindle 7 passes slightly below the upper end of the lateral sides of the door 6 and a point 8 of at least one of these ends is connected to a point 10 of the chassis situated in front of the pivoting axis 2 of the skip. One of the rear uprights 5 at least, comprises on its outer face, very close to its base, a catch 11 whose branch 13, directed towards the rear and curved at its end traps a stud 14 of the door 6. The catch comprises a small rod 15, perpendicular to the branch 13, the free end of which is connected to a point 17 of the chassis in front of the axis 2.

Description

La présente invention concerne un système d'ouverture et de fermeture automatiques de la porte arrière d'une benne basculante. The present invention relates to an automatic opening and closing system for the rear door of a tipper body.

En général, les portes arrière de bennes basculantes sont des panneaux rectangulaires soutenus par leurs deux coins supérieurs aux coins supérieurs arrière des ridelles ou aux montants arrière de fixation desdites ridelles. Elles sont montées pivotantes autour de ces points de liaison et sont maintenues fermées à l'aide de taquets solidaires des ridelles, ou des montants arrière, ou du côté arrière du plateau de la benne. In general, the rear doors of tipping bodies are rectangular panels supported by their two upper corners at the rear upper corners of the drop sides or at the rear mounting posts of said drop sides. They are pivotally mounted around these connection points and are kept closed by means of cleats secured to the drop sides, or to the rear uprights, or to the rear side of the bucket platform.

Un objet de la présente invention consiste à prévoir un système qui libère automatiquement les taquets de fermeture dès que la benne commence à se lever et qui les referme quand la benne revient à l'horizontale. An object of the present invention is to provide a system which automatically releases the closing lugs as soon as the body begins to lift and which closes them when the body returns to horizontal.

Un autre objet de l'invention consiste à prévoir un système qui ouvre automatiquement la porte, une fois que les taquets sont libérés, quand la benne se lève, ladite porte revenant en position fermée par gravité quand la benne revient à l'horizontale. Another object of the invention is to provide a system which automatically opens the door, once the cleats are released, when the bucket lifts, said door returning to the closed position by gravity when the bucket returns to the horizontal.

Selon une caractéristique de l'invention, la porte arrière pivote autour d'un axe horizontal supporté par les extrémités supérieurs des montants arrière des ridelles, lesdites extrémités se trouvant au moins à la hauteur du bord supérieur des ridelles, ledit axe passant légèrement au-dessous de l'extrémité supérieure des côtés latéraux de la porte, un point d'au moins un côté latéral de la porte, au-dessus de l'axe de rotation, étant relié par une tige rigide ou souple à un point du côté correspondant du châssis situé en avant de l'axe de pivotement de la benne. According to a characteristic of the invention, the rear door pivots about a horizontal axis supported by the upper ends of the rear uprights of the drop sides, said ends being at least at the height of the upper edge of the drop sides, said axis passing slightly at below the upper end of the lateral sides of the door, a point of at least one lateral side of the door, above the axis of rotation, being connected by a rigid or flexible rod to a point on the corresponding side of the chassis located in front of the pivot axis of the bucket.

Selon une autre caractéristique de l'invention, au moins un des montants arrière de fixation des ridelles, ou la partie arrière de la ridelle elle-meme, comporte sur sa face extérieure, très près de sa base, un axe horizontal dirigé vers l'extérieur sur lequel est monté pivotant un taquet comportant une branche dirigée vers l'arrière, recourbée à son extrémité, et sensiblement horizontale quand la benne est abaissée, le taquet comportant également une biellette dirigée vers le haut par rapport à ladite branche, l'extrémité libre de la biellette étant reliée par une tige rigide ou souple à un point du côté correspondant du châssis qui se trouve en avant de l'axe de rotation de la benne, le côté correspondant de la porte arrière comportant un ergot qui est pris dans la courbure de la branche dudit taquet quand la benne est abaissée.  According to another characteristic of the invention, at least one of the rear uprights for fixing the side panels, or the rear part of the side panel itself, has on its external face, very close to its base, a horizontal axis directed towards the exterior on which is pivotally mounted a cleat comprising a branch directed towards the rear, curved at its end, and substantially horizontal when the bucket is lowered, the cleat also comprising a link directed upwards relative to said branch, the end free of the link being connected by a rigid or flexible rod to a point on the corresponding side of the chassis which is in front of the axis of rotation of the bucket, the corresponding side of the rear door having a lug which is caught in the curvature of the branch of said cleat when the bucket is lowered.

Les caracteristiques de l'invention, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:
la Fig. 1 est une vue de côté de l'arrière d'une benne selon l'invention, la benne étant abaissée, et
la Fig. 2 est une vue de côté de l'arrière de la benne de la Fig.The characteristics of the invention, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
Fig. 1 is a side view of the rear of a bucket according to the invention, the bucket being lowered, and
Fig. 2 is a side view of the rear of the bucket of FIG.

1, la benne étant levée.1, the bucket being lifted.

La benne 1 pivote autour d'un axe horizontal 2 solidaire d'un châssis 3. Chacun des côtés latéraux de la benne 1 est fermé par une ridelle 4. La ridelle 4 est fixée au plateau de la benne par des montants, les montants arrière portant la référence numérique 5. Les montants 5 dépassent au-dessus des bords supérieurs des ridelles 4. The bucket 1 pivots about a horizontal axis 2 secured to a chassis 3. Each of the lateral sides of the bucket 1 is closed by a side panel 4. The side panel 4 is fixed to the platform of the bucket by uprights, the rear uprights bearing the reference numeral 5. The uprights 5 protrude above the upper edges of the drop sides 4.

L'arrière de la benne 1 est fermé par une porte 6. Celle-ci est un panneau rectangulaire monté pivotant autour d'un axe horizontal 7 passant un peu au dessous des extrémités supérieures de ses côtés latéraux et porté par les extrémités supérieures des montants 5. Un point 8 d'au moins un côté latéral de la porte 6, situé au-dessus de l'axe 7, est relié par une tige rigide ou souple 9 à un point 10 du châssis 3, situé en avant de l'axe de rotation 2 de la benne 1.The rear of the bucket 1 is closed by a door 6. This is a rectangular panel mounted pivoting about a horizontal axis 7 passing a little below the upper ends of its lateral sides and carried by the upper ends of the uprights 5. A point 8 of at least one lateral side of the door 6, located above the axis 7, is connected by a rigid or flexible rod 9 to a point 10 of the chassis 3, located in front of the axis of rotation 2 of the bucket 1.

Un taquet 11 est monté pivotant autour d'un axe horizontal 12 sur la face extérieure d'au moins un montant 5, très près de la base dudit montant. Le taquet 11 comporte une branche 13 dirigée vers l'extérieur, l'extrémité libre de la branche 13 étant recourbée vers le bas. A la
Fig. 1, le côté de la porte 6 comporte un ergot 14 emprisonné dans la courbure de la branche 13 qui est sensiblement horizontale. A hauteur de l'axe 12, une biellette 15, dirigée vers le haut, est solidaire de la branche 13. Son extrémité libre est reliée par une tige rigide ou souple 16 à un point 17 du châssis situé en avant de l'axe de pivotement 2 de la benne i. En pratique, le point 17 et le point 10 peuvent être confondus.A cleat 11 is pivotally mounted about a horizontal axis 12 on the outer face of at least one upright 5, very close to the base of said upright. The cleat 11 has a branch 13 directed outwards, the free end of the branch 13 being bent downwards. To the
Fig. 1, the side of the door 6 has a lug 14 trapped in the curvature of the branch 13 which is substantially horizontal. At the height of the axis 12, a link 15, directed upwards, is integral with the branch 13. Its free end is connected by a rigid or flexible rod 16 to a point 17 of the chassis located in front of the axis of pivot 2 of the bucket i. In practice, point 17 and point 10 can be confused.

Quand la benne est abaissée, la porte 6 est verticale et elle est maintenue fermée par l'ergot 14 emprisonné dans la courbure de la branche 13 du taquet 11. Quand la benne se relève, le point supérieur de la biellette 15 passe en avant de l'axe 12 et relève donc la branche 13 qui libère l'ergot 14. En même temps, le point 8 est attiré en avant de l'axe 7 de pivotement de la porte 6 par la tige 9 et la porte 6 se relève.  When the bucket is lowered, the door 6 is vertical and it is kept closed by the lug 14 trapped in the curvature of the branch 13 of the cleat 11. When the bucket is raised, the upper point of the link 15 passes in front of the axis 12 and therefore raises the branch 13 which releases the lug 14. At the same time, the point 8 is attracted in front of the pivot axis 7 of the door 6 by the rod 9 and the door 6 is raised.

Quand la benne s'abaisse à nouveau, le point 8 est relâché et la porte 6 retourne à sa position verticale par gravité. En arrivant à la position verticale, la branche 13 du taquet 11 reprend position au-dessus de l'ergot 14 et l'emprisonne. La porte est bloquée. When the bucket lowers again, point 8 is released and door 6 returns to its vertical position by gravity. Arriving at the vertical position, the branch 13 of the cleat 11 takes up position above the lug 14 and traps it. The door is blocked.

Bien que le système monté sur un seul côté du véhicule puisse être suffisant pour faire fonctionner la porte automatique, en pratique, le système est monté sur les deux côtes du véhicule.  Although the system mounted on one side of the vehicle may be sufficient to operate the automatic door, in practice, the system is mounted on both sides of the vehicle.
