Description

La présente invention concerne un appareil de levage et de manutention de panneaux en matériaux bois, plâtre ou autre, en vue de permettre à un seul ouvrier de hisser la plaque dans sa position définitive pour procéder à sa fixation aux plafonds horizontaux ou inclinés d'une construction.The present invention relates to an apparatus for lifting and handling panels made of wood, plaster or other materials, with a view to enabling a single worker to hoist the plate into its final position in order to fix it to the horizontal or inclined ceilings of a construction.

L'état connu de la technique propose ce type de matériel objet de plusieurs brevets dont ceux du demandeur FR 82 21785 , FR 01 13237 et EP1 302 607 A1 The known state of the art offers this type of material subject to several patents including those of the applicant FR 82 21785 , FR 01 13237 and EP1 302 607 A1

La présente invention a pour but de supprimer certains inconvénients sous la forme d'améliorations apportées aux appareils existants de façon à faciliter leur mise en oeuvre, leur manipulation, leur efficacité opérationnelle et leur transport sur les lieux de travail.The object of the present invention is to eliminate certain disadvantages in the form of improvements made to existing apparatus so as to facilitate their implementation, their handling, their operational efficiency and their transport in the workplace.

L'appareil de levage est composé d'un mât télescopique dont le déploiement est obtenu au moyen d'un système de mouflage de câbles et de sangle activée par un treuil, d'une base pliante et d'un pupitre réglable articulé supportant les plaques. Ce mât peut s'insérer dans la base suivant plusieurs orientations permettant d'améliorer l'ergonomie des différentes positions de travail et d'optimiser la stabilité de façon rapide et facile.The hoist consists of a telescopic mast, the deployment of which is achieved by means of a rope hoisting system and winch-activated webbing, a folding base and an articulated adjustable desk supporting the plates . This mast can be inserted in the base along several orientations to improve the ergonomics of the different work positions and to optimize stability quickly and easily.

L'ajout d'une articulation combinée à un coulissement permet de supporter efficacement des plaques de différentes dimensions et particulièrement les petites (30 à 50 cm) et ce dans des endroits les plus difficiles ou près des murs. Cette disposition permet aussi de rendre le pupitre très compact une fois replié pour faciliter son stockage et son transport.The addition of a hinge combined with a slide makes it possible to effectively support plates of different dimensions and particularly small ones (30 to 50 cm) in the most difficult places or near the walls. This arrangement also makes the console very compact once folded for easy storage and transportation.

Le tube central du pupitre peut se déplacer pour faire descendre la plaque au ras du sol lors de la pose sur des plafonds inclinés dits "rampants" dans des combles.The central tube of the desk can move to bring the plate down to the ground when laying on sloped ceilings called "crawling" in the attic.

Enfin, le système de poulie est conçu à l'aide d'une double poulie particulière pour permettre d'obtenir un ensemble de deux câbles dont un tendu dit de travail et l'autre détendu dit de sécurité, pour ainsi éviter la chute du pupitre sur l'utilisateur en cas de rupture du premier câble de travail.

Selon les figures 1, 2, 3, l'appareil de levage (A) est composé d'une base articulée (B) dans laquelle vient s'insérer le mât télescopique (M) de façon non permanente. Le pupitre (P) vient s'encastrer sur le mât télescopique (M), pouvant prendre plusieurs positions. La base articulée (B) possède deux logements (1, 2) formant une croix, qui peuvent recevoir le mât télescopique (M) et qui permettent deux orientations de celui-ci et de la base articulée (B) différentes de 90° et donc des positions angulaires différentes du pupitre (P) par rapport à la base articulée (B), ce qui facilite l'ergonomie de manipulation et optimise la stabilité du produit dans différents cas de pose de plaques (plafonds, petites plaques, rampants).According to figures 1 , 2 , 3 the lifting apparatus (A) is composed of an articulated base (B) in which the telescopic mast (M) is inserted non-permanently. The console (P) is embedded on the telescopic mast (M), which can take several positions. The articulated base (B) has two housings (1, 2) forming a cross, which can receive the telescopic mast (M) and which allow two orientations of the latter and the articulated base (B) different from 90 ° and therefore different angular positions of the desk (P) relative to the articulated base (B), which facilitates the handling ergonomics and optimizes the stability of the product in different cases of laying plates (ceilings, small plates, crawling).

Selon les figures 2, 4, 5 et 6, la base articulée (B) est composée d'un pied fixe (4) et de deux pieds pivotants (5, 5') par rapport à la platine (6) suivant l'axe défini par les boulons (7) (7'). Chacun des deux pieds pivotants (5, 5') est pourvu d'un verrou à ressort (8, 8') qui vient s'engager dans les orifices (3a, 3b, 3c, 3d, 3a', 3b', 3c', 3d') de la platine (6) de façon à immobiliser les pieds pivotants (5, 5') dans chacune de ces quatre positions définies par ces orifices (3a, 3b, 3c, 3d, 3a', 3b', 3c', 3d') de la platine (6).According to figures 2 , 4 , 5 and 6 , the articulated base (B) is composed of a fixed foot (4) and two pivoting feet (5, 5 ') with respect to the plate (6) along the axis defined by the bolts (7) (7' ). Each of the two pivoting feet (5, 5 ') is provided with a spring latch (8, 8') which engages in the orifices (3a, 3b, 3c, 3d, 3a ', 3b', 3c ' , 3d ') of the plate (6) so as to immobilize the pivoting feet (5, 5') in each of these four positions defined by these orifices (3a, 3b, 3c, 3d, 3a ', 3b', 3c ' , 3d ') of the plate (6).

Selon les figures 4, 5 et 6, lorsque les verrous à ressort (8, 8') sont engagés dans les orifices (3a, 3a') l'appareil est en position repliée pour son transport.According to Figures 4, 5 and 6 when the spring latches (8, 8 ') are engaged in the openings (3a, 3a') the apparatus is in the folded position for transport.

Selon les figures 2, 3 et 4, lorsque les verrous à ressort (8, 8') sont engagés dans les orifices (3c, 3c'), les pieds pivotants (5, 5') sont écartés au maximum conférant une bonne stabilité pour l'appareil de levage (A).According to figures 2 , 3 and 4 when the spring latches (8, 8 ') are engaged in the orifices (3c, 3c'), the pivoting feet (5, 5 ') are spaced apart at a maximum giving good stability for the lifting device (A) .

Selon les figures 4, 5 et 7, lorsque les verrous à ressort (8, 8') sont engagés dans les orifices (3d, 3d'), les deux pieds pivotants (5, 5') sont moins écartés de façon à permettre le passage de l'appareil dans les portes sans démontage du pupitre (P).According to Figures 4, 5 and 7 when the spring latches (8, 8 ') are engaged in the orifices (3d, 3d'), the two pivoting feet (5, 5 ') are less spaced so as to allow the passage of the apparatus in the doors without dismantling the console (P).

Selon les figures 4 et 8, lorsque les verrous à ressort (8, 8') sont engagés dans l'orifice (3b, 3b'), les deux pieds pivotants (5, 5') forment un angle de 150° permettant d'approcher l'appareil de levage (A) au plus près des murs facilitant ainsi la pose de plaques de petites largeurs aux plafonds, le long des murs.According to figures 4 and 8 when the spring latches (8, 8 ') are engaged in the hole (3b, 3b'), the two pivoting feet (5, 5 ') form an angle of 150 ° to approach the lifting apparatus (A) closer to the walls, making it easier to install small slabs on the ceilings along the walls.

Selon les figures 3, 9, 10, 11 et 12, le pupitre (P) est composé de bras pivotants (9, 9'). La rotation de ses bras pivotants (9, 9') est réalisée par l'intermédiaire des platines (11, 11') soudées aux supports de bras (10, 10') et les contre platines (12, 12') liées aux bras pivotants (9, 9') via la rotation autour des axes définis par les boulons (13, 13'). La translation des bras pivotants (9, 9') est réalisée par leur forme en glissière dans laquelle les contre platines (12, 12') glissent. L'immobilisation de ces bras pivotants est réalisée par des verrous à ressort (14, 14') liés aux contre platines (12, 12'). Ces verrous à ressort (14, 14') pénètrent dans les orifices (15a, 15b, 15c, 15a', 15b', 15c') réalisés sur les bras pivotants (9, 9') offrant trois positions possibles par rapport au pupitre (P).According to figures 3 , 9 , 10 , 11 and 12 , the desk (P) is composed of pivoting arms (9, 9 '). The rotation of its pivoting arms (9, 9 ') is effected by means of the plates (11, 11') welded to the arm supports (10, 10 ') and the counter plates (12, 12') connected to the arms pivoting (9, 9 ') via the rotation about the axes defined by the bolts (13, 13'). The translation of the pivoting arms (9, 9 ') is achieved by their slider shape in which the counter plates (12, 12') slide. The immobilization of these pivoting arms is performed by spring latches (14, 14 ') connected to the counter plates (12, 12'). These spring latches (14, 14 ') penetrate into the orifices (15a, 15b, 15c, 15a', 15b ', 15c') made on the pivoting arms (9, 9 ') providing three possible positions with respect to the desk ( P).

Selon les figures 3, 8, 9 et 10, lorsque les verrous à ressort (14, 14') sont positionnés dans les orifices (15c, 15c') des bras pivotants (9, 9') du pupitre (P), ce dernier peut supporter des petites plaques de plâtre de 30 à 50 cm de large en les appuyant sur le tube principal (16).According to figures 3 , 8 , 9 and 10 when the spring locks (14, 14 ') are positioned in the orifices (15c, 15c ') of the pivoting arms (9, 9') of the console (P), the latter can support small plasterboards 30 to 50 cm wide by pressing them on the main tube (16). ).

Selon les figures 3, 9 et 10, les verrous à ressort (14, 14') sont positionnés dans les orifices (15b, 15b') des bras pivotants (9, 9') permettant ainsi au pupitre (P) de supporter les plaques de largeur standard de 1, 2 m.According to figures 3 , 9 and 10 , the spring latches (14, 14 ') are positioned in the orifices (15b, 15b') of the pivoting arms (9, 9 ') thus allowing the desk (P) to support the standard width plates of 1.2 m .

Selon les figures 3, 9 10 et 12, la position des verrous à ressort (14, 14') dans les orifices (15a, 15a') combinée avec la rotation des bras pivotants (9, 9') réalisée par les articulations composées des platines (11, 11') et des contre platines (12, 12') permettent de replier de façon compacte les bras pivotants (9, 9') en diminuant la longueur du pupitre (P).According to figures 3 , 9 10 and 12 the position of the spring latches (14, 14 ') in the orifices (15a, 15a') combined with the rotation of the pivoting arms (9, 9 ') carried by the joints composed of the plates (11, 11') and against platens (12, 12 ') can compactly fold the pivoting arms (9, 9') by decreasing the length of the desk (P).

Selon les figures 12 et 13, le pupitre (P) permet la translation du tube principal (16) par rapport au châssis central (17) via deux chapes (19, 19') solidaires du châssis central (17) ; deux poignées à vis (18, 18') permettent de serrer ou desserrer les chapes (19, 19') libérant ou non la translation du tube principal (16).According to figures 12 and 13 , the console (P) allows the translation of the main tube (16) relative to the central frame (17) via two yokes (19, 19 ') integral with the central frame (17); two screw handles (18, 18 ') make it possible to tighten or loosen the clevises (19, 19'), freeing or not the translation of the main tube (16).

Selon les figures 13, 14 et 15, le pupitre (P) peut prendre différentes configurations suivant la position du tube principal (16) par rapport au châssis central (17). Ainsi le tube principal (16) descendu en translation par rapport au châssis central (17) permet au pupitre (P) de descendre jusqu'au sol pour poser les plaques dans un comble dont le plafond incliné démarre au niveau du sol.According to figures 13 , 14 and 15 , the console (P) can take different configurations depending on the position of the main tube (16) relative to the central frame (17). Thus the main tube (16) lowered in translation relative to the central frame (17) allows the desk (P) to go down to the ground to put the plates in a roof whose inclined ceiling starts at ground level.

Selon les figures 16 et 17, le système de câbles de levage est conçu pour chaque mât de manière identique à celui décrit entre les mâts (20, 21). Deux câbles (23, 23') de longueur identique, fixés à une de leur extrémité dans la partie basse du mât (20) par un axe (24) et à leur autre extrémité au mât (21) par un axe (25), passent autour de la poulie (22). Cette poulie (22) a deux réas (22a, 22b) de profondeurs différentes qui permettent d'avoir un câble (23) en tension et un câble (23') détendu, qui sert de câble de sécurité. Cette conception rend le système économique et simple en montage et en maintenance.According to figures 16 and 17 , the hoisting rope system is designed for each mast in the same manner as that described between the masts (20, 21). Two cables (23, 23 ') of identical length, fixed at one of their end in the lower part of the mast (20) by an axis (24) and at their other end to the mast (21) by an axis (25), pass around the pulley (22). This pulley (22) has two sheaves (22a, 22b) of different depths that allow to have a cable (23) in tension and a cable (23 ') expanded, which serves as security cable. This design makes the system economical and simple in assembly and maintenance.
