Description
La présente invention vise un dispositif de levage par sangles et cales d'appui orientables pour véhicules automobiles. The present invention relates to a lifting device by straps and adjustable support wedges for motor vehicles.
I1 est connu de lever les véhicules automobiles, en vue de leur entretien ou réparation au moyen de sangles reliées à un palonnier accroché à un palan, monte sur rail-support. Ce mode de levage s'effectue soit de par le pavillon du véhicule soit encore de par le bas de la caisse. I1 is known to lift motor vehicles, for their maintenance or repair by means of straps connected to a lifting beam attached to a hoist, mounted on support rail. This lifting mode is carried out either from the roof of the vehicle or from the bottom of the body.
Dans le premier cas, les portières doivent être démontées pour autoriser le passage des sangles et les habitacles sont souvent déformés lors du levage avec toutes les conséquence de montage des pièces adjacentes.Deplus le moteur doit être retiré. In the first case, the doors must be dismantled to allow the passage of the straps and the cockpits are often deformed during lifting with all the consequences of mounting adjacent parts. In addition, the engine must be removed.
Dans le deuxième cas, les sangles passant au-dessous de la caisse provoquent l'écrasement des bas de caisse, des tringleries, tuyau d'échappement ou autre organe tandis que les portières fermées ne peuvent pas être ouvertes tout en subissant des dépréciations. In the second case, the straps passing under the body cause crushing of the rocker panels, linkages, exhaust pipe or other body while the closed doors cannot be opened while undergoing depreciation.
C'est donc pour obvier à ces inconvénients qu'il est apparu nécessaire de réaliser un dispositif de levage par sangles et cales d'appui orientables pour véhicules automobiles. It is therefore in order to overcome these drawbacks that it appeared necessary to produce a lifting device by straps and adjustable support wedges for motor vehicles.
Selon une première caractéristique, ce dispositif comprend un moyen de levage proprement dit tels que des palonniers renforcés, avec moyen de dégagement des chaînes des palans de suspension et d'accrochage des extrémités de chacune des sangles qui entourent transversalement le bas de caisse, tandis que des cales transversales déportées, à serrage et pivotement automatique, adaptables sur les longerons du chassis ou sur le profil de la coque, autorisent le guidage et le déport tant inférieur que transversal des sangles par rapport au profil du véhicule en évitant toute-détérioration. According to a first characteristic, this device comprises a lifting means proper such as reinforced lifting beams, with means for disengaging the chains from the suspension hoists and for hooking the ends of each of the straps which transversely surround the rocker panel, while offset transverse wedges, with automatic tightening and pivoting, adaptable to the frame rails or to the profile of the hull, allow the guiding and the offset, both lower and transverse of the straps relative to the profile of the vehicle, avoiding any deterioration.
Selon une autre caractéristique, chaque palonnier est établi avec une poutretubulaire solidaire à ses extrémités dlune barre de levage formant triangulation et crochets débordants à ses extrémités pour l'engagement des boucles de la sangle, tandis que des étriers transversaux avec gaine de protection permettent l'appui des chaînes de manoeuvre du palan. According to another characteristic, each lifter is established with a tubular beam integral at its ends with a lifting bar forming a triangulation and protruding hooks at its ends for engaging the loops of the strap, while transverse stirrups with protective sheath allow the support of the hoist operating chains.
Selon une autre caractéristique, chaque cale transversale profilée avec joues inférieures de guidage de la sangle, forme à sa partie supérieure un mors fixe, disposé en regard d un mors mobile rappelé par ressort en vue d'assurer le pinçage et la fixation de ladite cale sur le longeron du châssis ou sur le profil de la coque de la voiture, en autorisant un léger pivotement de cale lors de la mise en tension de la sangle et du levage ; un moyen manuel par levier assurant l'ouverture du mors mobile à l'encontre du ressort. According to another characteristic, each profiled transverse wedge with lower cheeks for guiding the strap, forms at its upper part a fixed jaw, disposed opposite a movable jaw returned by spring in order to pinch and fix said wedge on the chassis beam or on the profile of the car hull, allowing slight wedge pivoting when tensioning the strap and lifting; manual means by lever ensuring the opening of the movable jaw against the spring.
Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description. These characteristics and others will emerge clearly from the following description.
Pour fixer l'objet de l'invention, sans toutefois le limiter, dans les dessins annexés

La figure 6 est, à petite échelle, une vue transversale illustrant la fixation et l'adaptation de la cale sur le châssis ou coque du véhicule, mais avant l'effort de levage. Figure 6 is, on a small scale, a transverse view illustrating the fixing and adaptation of the wedge on the chassis or hull of the vehicle, but before the lifting effort.
La figure 7 est une vue semblable à la figure 6, mais après l'effort de levage engendrant un pivotement - de la cale. Figure 7 is a view similar to Figure 6, but after the lifting effort causing a pivoting - of the wedge.
Ce dispositif de levage par sangles et cales d'appui orientables pour véhicules automobiles comporte au moins deux palonniers identiques (P) de longueurs supérieures à celle du gabarit transversal du véhicule avec respectivement une poutre tubulaire (1) travaillant-au flambage et dont les extrémités supérieures sont solidaires par soudure ou autrement d'une barre de levage (-2) formant, triangulation de par ses membrures axiales de renforcement (3)jet crochets extrêmes (2a) pour 1' engagement des boucles (4a) de la sangle correspondante (4). This lifting device by straps and adjustable support wedges for motor vehicles comprises at least two identical lifting beams (P) of lengths greater than that of the transverse gauge of the vehicle with respectively a tubular beam (1) working-buckling and whose ends upper are secured by welding or otherwise to a lifting bar (-2) forming, triangulation by its axial reinforcing members (3) jet extreme hooks (2a) for 1 engagement of the loops (4a) of the corresponding strap ( 4).
Des guides (5) fixés aux extrémités de la poutre (1), forment respecivement des boucles débordantes et espacées < Sa) reliées par une section droite (5b) de manière à autoriser le guidage transversal et l'appui des brins de la chaîne (Ca) du palan (C) monté à la façon connu sur rail.Guides (5) fixed to the ends of the beam (1), respectively form protruding and spaced loops <Sa) connected by a straight section (5b) so as to allow transverse guidance and support of the strands of the chain ( Ca) of the hoist (C) mounted in the known manner on a rail.
I1 faut considérer que les guides (5) reçoivent un gai nage n matière souple de protection contre la carrosserie du véhicule. I1 must be considered that the guides (5) receive a coating n flexible material of protection against the vehicle body.
Chaque sangle (4) entoure le profil transversal du véhicule et exerce l'effort de levage au moyen de cales appui orientables (6) fixées sur les longerons du châssis ou sur le profil (L) de la coque du véhicule. Chaque cale (6) est destinée à éloigner la sangle (4) tant du profil transversal (portières) que du dessous de la caisse et de ses organes inhérents. Each strap (4) surrounds the transverse profile of the vehicle and exerts the lifting force by means of adjustable support shims (6) fixed on the frame rails or on the profile (L) of the vehicle hull. Each wedge (6) is intended to move the strap (4) away from both the transverse profile (doors) and the underside of the body and its inherent members.
A cet effet, chaque cale profilée (6) forme à sa partie inférieure un profil extérieur arrondi muni de joues parallèles (6a) pour autoriser le guidage et l'appui de la section de la sangle (4) et son dégagement au moyen d'entretoises (7). A sa partie supérieure, la cale (6) forme un bossage (6b) se raccordant à un dégagement penté (6c), tout en constituant transversalement un mors fixe (6d). Un mors mobile (8) disposé en regard du mors fixe (6d) coulisse librement par l'intermédiaire d'un guide axial (9) engagé dans un trou correspondant (6e), et est rappelé en permanence en position de fermeture par des ressorts à badin (10) disposés latéralement dans des dégagements du corps fle ladite cale (6). To this end, each profiled wedge (6) forms at its lower part a rounded external profile provided with parallel cheeks (6a) to allow the guide and the support of the section of the strap (4) and its release by means of spacers (7). At its upper part, the wedge (6) forms a boss (6b) connecting to a sloping clearance (6c), while transversely constituting a fixed jaw (6d). A movable jaw (8) disposed opposite the fixed jaw (6d) slides freely by means of an axial guide (9) engaged in a corresponding hole (6e), and is permanently returned to the closed position by springs with baffle (10) arranged laterally in recesses of the body fle said wedge (6).
Un carter (11) solidaire du mors mobile (8) assure de par sa section en U, le chevauchement de la section du corps (6) tout en assurant le recouvrement et la protection des ressorts (in). A casing (11) integral with the movable jaw (8) ensures, by its U-shaped section, the overlapping of the body section (6) while ensuring the recovery and protection of the springs (in).
I1 faut considérer que le mors mobile (8) est commandé en position d'ouverture maximum d'engagement, sur le profil (7) du châssis ou de la coque, au moyen de deux tiges latérales (12) engagées à pivotement de par leurs extrémités recourbées (12a)- et accouplées à l'opposé en (12b) aux branches (13a) d'un étrier (13). Ces branches (13a) reliées par une entretoise (13b) formant poignée de manoeuvre chevauchent la section transversale du corps (6) et s'articulent sur un axe surbaissé (14) constituant de chaque côté l'un des sommets d'une triangulation formée par les extrémités (12a) et l'accou- plement (12bu de manière à obtenir un verrouillage en position d'ouverture de rabattement de la poignée. I1 must be considered that the movable jaw (8) is controlled in the maximum open engagement position, on the profile (7) of the chassis or the shell, by means of two lateral rods (12) pivotally engaged by their curved ends (12a) - and coupled opposite (12b) to the arms (13a) of a stirrup (13). These branches (13a) connected by a spacer (13b) forming an operating handle overlap the cross section of the body (6) and are articulated on a lowered axis (14) constituting on each side one of the vertices of a triangulation formed by the ends (12a) and the coupling (12bu so as to obtain a locking in the opening position of folding of the handle.
L'ouverture de la cale (6) permet ainsi d'adapter l'ouverture de ses mors (6d et 8) sur le profil (L) et sur les emplacements prévus, et d'agir ensuite vers le haut sur la pour gnée (13b) pour obtenir le serrage immédiat et automatique de la dite cale en position de levage, tout en éloignant la sangle (4) des deux faces adjacentes du véhicule comme indiqué et illustré figure 6. The opening of the wedge (6) thus makes it possible to adapt the opening of its jaws (6d and 8) on the profile (L) and on the locations provided, and then to act upwards on the for 13b) to obtain the immediate and automatic tightening of said wedge in the lifting position, while moving the strap (4) away from the two adjacent faces of the vehicle as shown and illustrated in FIG. 6.
Lors du levage du véhicule de par l'intermédiaire des palonniers (P), les sangles (4) sont mises en tension et les cales (6) pivotent légèrement vers l'extérieur, suivant flèche
F de la figure 7, en engendrant un effort de tension sur le profil (L) du châssis ou de la coque, qui est immédiatement annulé en comprimant les ressorts (10), pour obtenir l'ouverture proportionnelle du mors mobile (8).When lifting the vehicle through the lifting beams (P), the straps (4) are tensioned and the wedges (6) pivot slightly outwards, according to arrow
F of Figure 7, generating a tension force on the profile (L) of the chassis or the shell, which is immediately canceled by compressing the springs (10), to obtain the proportional opening of the movable jaw (8).
Cette ouverture du mors mobile (8) permet également de repousser les tiges (12) qui commandent en position inverse le rabattement automatique de la poignée (13b) solidaire des branches (13a) en position verticale d'effacement. Cette disposition intéressante évite tout débordement pouvant être cause d'accident. This opening of the movable jaw (8) also makes it possible to push back the rods (12) which control in the reverse position the automatic folding of the handle (13b) integral with the branches (13a) in the vertical erasing position. This interesting arrangement avoids any overflow that could cause an accident.
Les avantages ressortent bien de la description. The advantages are apparent from the description.
On souligne en particulier - La facilité de montage des cales sur le châssis ou coque de tout véhicule par une seule personne. In particular, we emphasize - The ease of mounting wedges on the chassis or hull of any vehicle by one person.
- L'élimination de toute déformation, par écrasement sur le fond de caisse, ou encore sur les organes fixes au-dessous du véhicule.- The elimination of any deformation, by crushing on the bottom of the body, or on the fixed components below the vehicle.
- La possibilité d'ouverture de portières lorsque le véhicule est levé.- The possibility of opening doors when the vehicle is lifted.
L'invention ne se limite aucunement à celui de ses modes d'application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plues spécialement été indiquées elle en embrasse au contraire toutes les variantes. The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts having been specially indicated, it on the contrary embraces all variants.
