This system includes a lock with a bolt 13 permanently forced towards its active locking position by an elastic member; this lock is actuated by a cam 15 which can move vertically and which acts on the arm 8 supporting the bolt. The bolt and its manoeuvring system are housed in a reinforcement 4 of the fixed part 1 of the upright.

Description

La présente invention concerne un perfectionnement au systeme de verrouillage des montants télescopiques de véhicules de transport à couverture rehaussable. The present invention relates to an improvement to the locking system of the telescopic uprights of transport vehicles with a cover that can be raised.

Le mouvement de la couverture est assure par les coulisses des montants, lesquelles sont mobiles verticalement sous l'effet, selon le cas, d'une commande individuelle ou d'une commande centralisée ; le verrouillage de ces coulisses étant également manuel ou automatique. The movement of the cover is ensured by the slides of the uprights, which are movable vertically under the effect, as the case may be, of an individual control or of a centralized control; the locking of these slides is also manual or automatic.

Dans le brevet FR A-2 393 692 par exemple, la couverture est rehaussée par étapes successives au moyen d'un levier de manoeuvre qui agit sur la coulisse du montant, pour la placer en position verrouillable grâce à une cheville introduite par l'opérateur. In patent FR A-2,393,692 for example, the cover is raised in successive stages by means of an operating lever which acts on the slide of the upright, to place it in the lockable position by means of a pin introduced by the operator .

Dans la demande de brevet 85 03000 de la demanderesse, la couverture est rehaussable globalement grâce notamment à des montants comportant des coulisses motrices, dont le verrouillage est automatique ; les montants intermédiaires sont verrouillés après coup par l'opérateur au moyen de chevilles. In the applicant's patent application 85 03000, the cover can be raised overall thanks in particular to uprights comprising driving slides, the locking of which is automatic; the intermediate uprights are locked afterwards by the operator by means of dowels.

I1 est apparu que la mise en place de ces chevilles, pour les montants intermédiaires, n'était pas pratique, compte-tenu de leur niveau relativement élevé par rapport au sol. It appeared that the installation of these pegs, for the intermediate uprights, was not practical, given their relatively high level relative to the ground.

L'invention vise à remédier à cet inconvenient en proposant un système de verrouillage des montants, dont la commande est nettement plus accessible, cette commande se situant à la partie basse des montants, à hauteur normale pour un opérateur. The invention aims to remedy this drawback by proposing a system for locking the uprights, the control of which is much more accessible, this control being located at the bottom of the uprights, at normal height for an operator.

Un autre objet de l'invention est de faciliter l'opération de verrouillage des montants, grâce à une action automatique des verrous ; ce verrouillage automatique des verrous facilite le travail de l'opérateur et offre une plus grande sécurité. Another object of the invention is to facilitate the operation of locking the uprights, thanks to an automatic action of the latches; this automatic locking of the locks facilitates the operator's work and offers greater security.

L'invention permet encore de laisser les montants, en toute sécurité, entre deux positions de verrouillage, lorsque par exemple, la couverture du véhicule repose directement sur le chargement. The invention also makes it possible to safely leave the uprights between two locking positions, for example when the vehicle cover rests directly on the load.

Le système de verrouillage selon l'invention comporte un verrou a pène actionné au moyen de deux organes de commande séparés, l'un des organes agissant en permanence sur le verrou, l'autre organe étant mis en oeuvre par un opérateur. The locking system according to the invention comprises a bolt bolt actuated by means of two separate control members, one of the members acting permanently on the lock, the other member being operated by an operator.

Selon une disposition préférentielle de l'invention, le verrou comporte un bras qui est articulé, sur la partie fixe du montant, autour d'un axe horizontal, ledit bras étant muni a l'une de ses extrémités d'un pène s'engageant dans l'un des crantages prévus sur la coulisse, et, a l'autre extrémité, d'un organe élastique en appui sur la partie fixe du montant pour solliciter en permanence le pène vers la position active de verrouillage. According to a preferred arrangement of the invention, the lock comprises an arm which is articulated, on the fixed part of the upright, about a horizontal axis, said arm being provided at one of its ends with an engaging bolt in one of the notches provided on the slide, and, at the other end, of an elastic member bearing on the fixed part of the upright to permanently urge the bolt towards the active locking position.

Selon une autre disposition de l'invention, le bras comporte, entre son axe d'articulation et le pene, une rampe inclinée par rapport a l'axe vertical du montant, qui coopère avec l'organe mis en oeuvre par l'opérateur. According to another arrangement of the invention, the arm comprises, between its hinge axis and the bolt, a ramp inclined relative to the vertical axis of the upright, which cooperates with the member used by the operator.

Selon l'invention, l'organe mis en oeuvre par l'opérateur pour placer le pène en position active de verrouillage, est constitué d'une came guidée verticalement dans la partie fixe du montant, cette came agit sur la rampe inclinée du bras, faisant pivoter ce dernier pour, dans un sens, dégager le pène du crantage de la coulisse, et le mettre en position inactive, et, dans l'autre sens, permettre au pène de se remettre automatiquement en position active de verrouillage dans le crantage prévu sur la coulisse. According to the invention, the member used by the operator to place the bolt in the active locking position, consists of a cam guided vertically in the fixed part of the upright, this cam acts on the inclined ramp of the arm, rotating the latter to, in one direction, release the bolt from the notching of the slide, and put it in the inactive position, and, in the other direction, allow the bolt to automatically return to the active locking position in the provided notching backstage.

Selon une autre disposition de l'invention, la came est actionnée par l'opérateur au moyen d'une poignée à excentrique, disposée en partie basse du montant. According to another arrangement of the invention, the cam is actuated by the operator by means of an eccentric handle, disposed in the lower part of the upright.

Toujours selon l'invention, le système de verrouillage est intégre dans un renfoncement en forme de U qui s'etend, dans la partie mediane, sur toute la hauteur de la partie fixe du montant de façon à ne pas amputer le gabarit du vehicule. Still according to the invention, the locking system is integrated in a U-shaped recess which extends, in the middle part, over the entire height of the fixed part of the upright so as not to amputate the size of the vehicle.

L'invention sera mieux comprise à 3:'aide de la description suivante et des dessins annexes, donnes à titre indicatif, et dans lesquels - la figure 1 est une vue de face externe d'un montant telescopique selon l'invention, - la figure 2 est une vue agrandie et en coupe, selon 2-2, de la figure 1, - la figure 3 est une vue agrandie et en coupe, selon 3-3, de la figure 2, - la figure 4 est une vue agrandie et en coupe, selon 4-4, de la figure 2. The invention will be better understood from 3: 'using the following description and the accompanying drawings, given for information only, and in which - Figure 1 is an external front view of a telescopic upright according to the invention, - the Figure 2 is an enlarged and sectional view, along 2-2, of Figure 1, - Figure 3 is an enlarged and sectional view, along 3-3, of Figure 2, - Figure 4 is an enlarged view and in section, according to 4-4, of FIG. 2.

Tel que represente figure 1, le montant telescopique est constitue d'une partie fixe 1, solidaire à sa partie basse du châssis 2 du vehicule, et d'une coulisse 3 qui apparait à la partie superieure de la partie fixe 1 ; cette coulisse 3, partiellement representee, est solidaire de la couverture, non representee du vehicule. As shown in Figure 1, the telescopic upright consists of a fixed part 1, integral at its lower part with the chassis 2 of the vehicle, and a slide 3 which appears at the upper part of the fixed part 1; this slide 3, partially shown, is secured to the cover, not shown of the vehicle.

Habituellement la partie fixe 1 du montant et la coulisse 3 ont une section rectangulaire ; l'epaisseur du montant entant la plus faible possible pour ne pas limiter le gabarit du véhicule. Usually the fixed part 1 of the upright and the slide 3 have a rectangular section; the thickness of the upright entering as small as possible so as not to limit the size of the vehicle.

Telle qu'elle apparait figures 1, 3 et 4, la partie fixe 1 du montant comporte un renfoncement 4 conformé sur toute la hauteur et au centre de son aile externe 5 ; ce renfoncement, en forme de U ouvert vers l'extérieur, contient tout le système de commande de verrouillage de la coulisse 3 de façon à conserver un gabarit de véhicule identique à celui des véhicules à montants classiques. As it appears in Figures 1, 3 and 4, the fixed part 1 of the upright has a recess 4 shaped over the entire height and at the center of its outer wing 5; this recess, in the form of a U open towards the outside, contains the entire control system for locking the slide 3 so as to maintain a vehicle gauge identical to that of vehicles with conventional uprights.

La coulisse 3 a une section adaptee à celle de la partie fixe 1 ; cette section est en forme de U avec des retours en bout des ailes laterales, orientes vers le renfoncement 4. The slide 3 has a section adapted to that of the fixed part 1; this section is U-shaped with returns at the end of the lateral wings, oriented towards the recess 4.

Le systeme de verrouillage est constitue d'une poignee à excentrique 6, classique, disposee en partie basse du renfoncement 4 ; cette poignee 6 actionne, par l'intermediaire d'une tige de commande 7, le verrou proprement dit dispose à la partie superieure de la partie fixe 1, dans le renfoncement 4. The locking system consists of an eccentric handle 6, conventional, arranged in the lower part of the recess 4; this handle 6 actuates, by means of a control rod 7, the bolt proper has at the upper part of the fixed part 1, in the recess 4.

Le verrou comprend un bras pivotant 8, monte sur un axe horizontal 9. La partie superieure 8b du bras 8, situee au-dessus de l'axe 9, reçoit l'organe elastique 10 pince entre ladite partie superieure 8b et le fond 11 du renfoncement 4, avec un bras de levier très court. The lock comprises a pivoting arm 8, mounted on a horizontal axis 9. The upper part 8b of the arm 8, located above the axis 9, receives the elastic member 10 clamp between said upper part 8b and the bottom 11 of the recess 4, with a very short lever arm.

La partie inferieure 8a du bras 8 comporte tout d'abord une rampe inclinee 12 puis-, à son extremite, un pène 13, oriente vers l'interieur, qui traverse le fond 11 du renfoncement 4, la coulisse 3 et le guide 14 de ladite coulisse ; ce guide 14 constitue la paroi interne de la partie fixe 1 du montant. The lower part 8a of the arm 8 firstly comprises an inclined ramp 12 then-, at its end, a bolt 13, oriented inwards, which crosses the bottom 11 of the recess 4, the slide 3 and the guide 14 of said slide; this guide 14 constitutes the internal wall of the fixed part 1 of the upright.

Entre la partie basse 8a du bras 8 et le fond 11 du renfoncement 4, on trouve la came 15 de manoeuvre dudit bras 8. Cette came 15 est solidaire de la tige de commande i, et comporte une butee 16 à son extremite superieure. La butée 16 agit sur la rampe inclinee 12 du bras 8 pour le faire pivoter autour de l'axe 9. Une traction vers le bas de la came 15 et de sa butee 16, au moyen de la poignee 6, provoque un pivotement du bras 8, ayant pour effet de comprimer l'organe elastique 10 et de degager le pène 13 du crantage 17 de la coulisse 3, en le faisant basculer vers l'exterieur. L'escamotage de la poignee 6, c'est-à-dire sa remise en position dans le renfoncement 4, selon la figure 1, provoque une elevation de la came 15 et de sa butee 16 le bras 8 est sollicite par l'organe elastique 10 de façon à presser le pène 13 qui, selon le cas, se positionne dans un crantage 17 de la coulisse 3 ou reste en appui sur cette dernière. Between the lower part 8a of the arm 8 and the bottom 11 of the recess 4, there is the cam 15 for operating said arm 8. This cam 15 is integral with the control rod i, and has a stop 16 at its upper end. The stop 16 acts on the inclined ramp 12 of the arm 8 to rotate it around the axis 9. A downward pull of the cam 15 and its stop 16, by means of the handle 6, causes the arm to pivot 8, having the effect of compressing the elastic member 10 and releasing the bolt 13 from the notch 17 of the slide 3, by tilting it towards the outside. The retraction of the handle 6, that is to say its repositioning in the recess 4, according to Figure 1, causes an elevation of the cam 15 and its stop 16 the arm 8 is biased by the member elastic 10 so as to press the bolt 13 which, as the case may be, is positioned in a notch 17 of the slide 3 or remains supported on the latter.

Le système de verrouillage est totalement positionne et integre dans le renfoncement 4 de la partie fixe 1 du montant ; le verrou est mis en place et il est maintenu dans le renfoncement 4 au moyen des paliers 18 de l'axe 9. The locking system is fully positioned and integrated in the recess 4 of the fixed part 1 of the upright; the lock is put in place and it is held in the recess 4 by means of the bearings 18 of the axis 9.

Ces paliers 18 sont par exemple, soudes sur les flancs du renfoncement 4, ainsi que le support de la poignee 6. These bearings 18 are, for example, welded on the sides of the recess 4, as well as the support of the handle 6.
