Description

BREVET D'INVENTION
La présente invention se rapporte à un dispositif de blocage automatique d'une benne basculante sur les fourches d'un chariot élévateur lorsque celles-ci sont engagées dans les supportsfourreaux du chassis porteur de ladite benne.PATENT
The present invention relates to an automatic locking device of a tilting skip on the forks of a forklift when the latter are engaged in the fork supports of the carrying frame of said skip.

Il est fréquent que ce type de benne, qui est solidaire d'un chassis porteur, soit enfourchée dans les supports-fourreaux, et soulevée sans aucun système de blocage, ce qui n'empêche pas à la benne de glisser lorsque les fourches présentent un certain angle d'inclinaison vers l'avant, et/ou lorsqu'elles sont humides.It is common that this type of bucket, which is integral with a carrying frame, is straddled in the sheath supports, and raised without any locking system, which does not prevent the bucket from slipping when the forks have a certain tilt angle forward, and / or when wet.

La présente invention a pour but de remédier à cet inconvénient, et de proposer un dispositif qui permet le blocage automatique des fourches du chariot élévateur dans les supports-fourreaux du chassis porteur lorsque celles-ci sont complêtement engagées, et que la benne est soulevée.The object of the present invention is to remedy this drawback, and to propose a device which allows the automatic locking of the forks of the forklift in the sleeve supports of the carrying frame when these are fully engaged, and the bucket is raised.

Le dispositif de blocage automatique de la benne, selon l'invention, confère une plus grande sécurité lors des manoeuvres.The automatic blocking device of the bucket, according to the invention, provides greater security during maneuvers.

Le dispositif de blocage automatique de la benne, selon l'invention, est constitue d'un étrier pivotant monté sur l'un des supports-fourreaux du chassis porteur.The automatic blocking device of the bucket, according to the invention, consists of a pivoting stirrup mounted on one of the sleeve supports of the carrying frame.

Un axe de basculement est monté entre les deux bras de l'étrier, et passé à travers un trou oblongue amenagé dans le support-fourreau ou est monté l'étrier, de telle sorte que le débattement de cet axe puisse jouer librement entre la position basse de l'étrier et la position haute, lorsque la benne est soulevée.A tilting axis is mounted between the two arms of the stirrup, and passed through an oblong hole made in the sheath support or the stirrup is mounted, so that the movement of this axis can play freely between the position lower of the caliper and the high position, when the bucket is raised.

L'étrier se trouve en position basse lorsque la benne repose sur le sol, les fourches du chariot peuvent alors être engagées dans les supports-fourreaux et l'axe de basculement se trouve en contact avec la partie supérieure de la fourche ou est situé l'étrier.The stirrup is in the low position when the bucket rests on the ground, the forks of the trolley can then be engaged in the sheath supports and the tilting axis is in contact with the upper part of the fork or is located l 'stirrup.

Lorsque les fourches du chariot élévateur remontrent, la fourche où est situé l'étrier remonte avec elle l'axe de basculement, ce qui a pour effet de faire remonter la partie arrière l'étrier et d'enserrer la fourche.When the forks of the forklift go up, the fork where the caliper is located goes up with it the tilting axis, which has the effect of raising the rear part of the caliper and enclosing the fork.

Lorsque la benne est reposée sur le sol, les fourches descendent dans la partie basse des supports-fourreaux, et l'étrier descend en position basse sous l'effet de son propre poids, ce qui permet de retirer les fourches du chariot élévateur.When the bucket is resting on the ground, the forks descend into the lower part of the fork supports, and the stirrup descends into the low position under the effect of its own weight, which allows the forks to be removed from the forklift.

L'invention sera mieux comprise à la suite de la description et des dessins annexés dans lesquels - la planche 1 représente la benne en perspective, - la planche 2 représente l'étrier monté sur le support-fourreau en vue de profil, - la planche 3 représente.l'étrier monté sur le support-fourreau en vue de dessus.The invention will be better understood following the description and the appended drawings in which - the board 1 represents the bucket in perspective, - the board 2 represents the stirrup mounted on the sheath support in profile view, - the board 3 represents the stirrup mounted on the sheath support in top view.

La benne basculante 1 est solidiaire d'un chassis porteur 2 muni de supports-fourreaux 3, destinés à recevoir les fourches 4 d'un chariot élévateur.The tilting skip 1 is made up of a carrying frame 2 provided with sheath supports 3, intended to receive the forks 4 of a forklift.

Sur l'un de ces supports-fourreaux 3, est fixé un palier 7, qui permet une articulation angulaire de l'étrier 6, entre les points
A' et A", autour d'un axe 5.On one of these sheath supports 3, a bearing 7 is fixed, which allows an angular articulation of the stirrup 6, between the points
A 'and A ", around an axis 5.

Dans cet étrier 6, est engagé un axe de basculement 8, monté entre les deux bras 9 de l'étrier 6, et bloqué de chaque côté à l'aide de goupilles.In this stirrup 6, is engaged a tilting axis 8, mounted between the two arms 9 of the stirrup 6, and locked on each side using pins.

Cet axe de basculement 8 est passé à travers un trou oblongue 10 aménagé dans le support-fourreau 3 de telle sorte que le debattement dudit axe puisse jouer librement entre la position basse de l'étrier en A" et sa position haute en A', lorsque la benne est soulevée. This tilting axis 8 is passed through an oblong hole 10 arranged in the sleeve support 3 so that the movement of said axis can play freely between the low position of the stirrup at A "and its high position at A ', when the bucket is raised.

Lorsque la benne 1 repose sur le sol, l'étrier 6 descend sous l'effet de son propre poids en position basse en A", les fourches 4 peuvent alors hêtre engagées dans les supports-fourreaux 3.When the bucket 1 rests on the ground, the stirrup 6 descends under the effect of its own weight in the low position at A ", the forks 4 can then be engaged in the sheath supports 3.

Lorsque les fourches 4 sont engagées, la fourche où est situé l'étrier 6 se retrouve en contact avec l'axe de basculement 8.When the forks 4 are engaged, the fork where the stirrup 6 is located finds itself in contact with the tilting axis 8.

Les fourches 4 du chariot élévateur peuvent alors être actionnées pour remonter la benne.The forks 4 of the forklift can then be actuated to raise the bucket.

La fourche 4 où est situé l'étrier 6 remonte avec elle l'axe de basculement 8 en B', ce qui a pour effet de faire remonter la partie arrière de l'étrier 6, et de bloquer liarriere de la fourche par un axe 10 monté sur les bras 9 de l'étrier 6.The fork 4 where the stirrup 6 is located rises with it the tilting axis 8 in B ', which has the effect of raising the rear part of the stirrup 6, and blocking the rear of the fork by an axis 10 mounted on the arms 9 of the stirrup 6.

Lorsque la benne 1 est reposée sur le sol, les fourches 4 descendent dans la partie basse des supports-fourreaux 3 en B", ce qui a pour effet de faire redescendre l'axe de basculement 8 avec l'étrier 6 qui se retrouve en position d'ouverture en A", sous l'effet de son propre poids, en libérant la fourche 4 de l'axe 11.When the bucket 1 is resting on the ground, the forks 4 descend into the lower part of the sheath supports 3 at B ", which has the effect of lowering the tilting axis 8 with the stirrup 6 which is found in open position in A ", under the effect of its own weight, freeing the fork 4 from the axis 11.

Les fourches 4 peuvent alors être retirées.The forks 4 can then be removed.

La présente invention n'est limitée à la forme de réalisation telle qu'elle ressort de la description et des dessins annexés, elle couvre toutes les variantes du mode de réalisation de l'étrier et de ses éléments constituants. The present invention is not limited to the embodiment as it emerges from the description and the appended drawings, it covers all the variants of the embodiment of the stirrup and of its constituent elements.
