L'état connu de la technique propose ce type de matériel, objet de plusieurs brevets dont les brevets français n° 2538437 et n° 2741901 et les brevets américains n° 2964293 et n° 3314553.The known state of the art proposes this type of material, object of several patents whose French Patent No. 2538437 and n ° 2741901 and U.S. Patent Nos. 2964293 and 3314553.

La présente invention a pour objet de supprimer certains inconvénients sous la forme d'améliorations apportées aux appareils existants, de façon à faciliter leur mise en oeuvre, leur manipulation et leur efficacité opérationnelle.The present invention aims to remove some disadvantages in the form of improvements to existing devices, so as to facilitate their implementation, handling and operational efficiency.

A cette fin, l'appareil de levage, composé dans sa partie principale d'un mât télescopique dont le déploiement est obtenu au moyen d'un système de mouflage d'un câble activé par un treuil, est caractérisé en ce que le mât est articulé à sa base sur le piétement repliable, de façon à obtenir un appareil totalement replié offrant un encombrement réduit et une parfaite compacité facilitant le transport et le stockage de l'appareil.For this purpose, the hoisting apparatus, consisting in its main part of a telescopic mast whose deployment is obtained by means of a hoisting system of a cable activated by a winch, is characterized in that the mast is articulated at its base on the folding base, so as to obtain a fully folded device offering a small footprint and perfect compactness for easy transport and storage of the device.

Selon une autre disposition, le mât se rabat au niveau et en prolongement des trois pieds composant le piétement et sur l'un desquels il vient se verrouiller. Le même système de verrouillage prévu dans une autre pièce du piétement permet de maintenir le mât en position verticale.According to another arrangement, the mast is folded at the level and extension of the three legs composing the base and on one of which it comes to lock. The same locking system provided in another part of the base makes it possible to keep the mast upright.

Selon une disposition particulière, la base non télescopique du mât comporte un dispositif de verrouillage de tous les éléments télescopiques du mât, de façon à solidariser l'ensemble et faciliter ainsi le transport ou les différentes manipulations de l'appareil de levage avant ou après son utilisation.According to one particular arrangement, the non-telescopic base of the mast includes a device for locking all the telescopic elements of the mast, so as to secure the assembly and thus facilitate the transport or the various manipulations of the hoist before or after its use.

Selon une disposition avantageuse, deux des trois pieds de piétement sont orientables horizontalement, avec toutefois la possibilité de les immobiliser suivant trois positions au moyen d'un verrou à ressort s'engageant dans l'un des orifices prévus dans une platine solidaire du piétement. Ces trois positions permettent de régler l'écartement des deux pieds orientables, soit dans la position écartée au maximum pour obtenir une bonne stabilité de l'appareil de levage en utilisation, soit dans la position écartement minimum pour permettre le passage dans les portes, soit dans la position dite repliée pour le transport et le stockage de l'appareil de levage.According to an advantageous arrangement, two of the three legs are horizontally adjustable, with the possibility, however, to immobilize them in three positions by means of a spring latch engaging in one of the orifices provided in a plate secured to the base. These three positions make it possible to adjust the spacing of the two steerable feet, that is to say in the most widely spaced position in order to obtain good stability of the lifting device in use, or in the minimum spacing position to allow passage through the doors, or in the so-called folded position for transporting and storing the lifting apparatus.

Selon une disposition particulière, l'embase du mât est équipée sur sa face inférieure d'un rouleau en matière semi-rigide, non agressive, de façon à éviter le contact des pièces métalliques sur les sols, tout en facilitant le déplacement de l'appareil replié.According to a particular provision, the base of the mast is equipped on its underside with a roller of semi-rigid material, non-aggressive, so as to avoid contact of the metal parts on the ground, while facilitating the movement of the device folded.

Selon une dernière disposition particulière, le préréglage de l'inclinaison du pupitre amovible support de plaque en appui sur l'extrémité supérieure du mât, est obtenu suivant le positionnement d'une poignée mobile immobilisée au moyen d'un ensemble écrou papillon et un axe-vis avec levier excentrique assurant un serrage efficace.According to a last particular provision, the presetting of the inclination of the removable plate support plate resting on the upper end of the mast, is obtained according to the positioning of a movable handle immobilized by means of a butterfly nut and an axle assembly. -vis with eccentric lever for efficient clamping.

Suivant les figures 1, 2, 4, 5, 13 et 15, l'appareil de levage se compose d'un piétement (1), d'un mât télescopique (2) et d'un pupitre support de plaque amovible (3). Le piétement (1) est constitué d'une chape (4) enveloppant sur trois faces la partie basse du mât télescopique (2) et réunissant deux platines (7) (37) tenant lieu de chapes d'articulation, elles-mêmes reliées par un axe (42) autour duquel tourne un fourreau (41) reliant les deux barres constitutives de chacun des deux pieds (5) orientables horizontalement, alors que les deux barres constitutives du pied (5a) fixe sont solidaires de la chape (4). Les trois pieds sont équipés d'une roue pivotante à frein (38).According to Figures 1, 2, 4, 5, 13 and 15, the lifting apparatus consists of a base (1), a telescopic pole (2) and a removable plate support (3). . The base (1) consists of a yoke (4) wrapping on three sides the lower part of the telescopic mast (2) and joining two plates (7) (37) in lieu of hinge clevises, themselves connected by an axis (42) around which turns a sheath (41) connecting the two constituent bars of each of the two feet (5) orientable horizontally, while the two bars constituting the fixed foot (5a) are integral with the yoke (4). The three legs are equipped with a brake swivel wheel (38).

Toujours suivant les figures 1, 2, 4, 5, 7, 13 et 15, chacun des deux pieds (5) orientables est pourvu d'un verrou à ressort (6) qui vient s'engager dans les orifices (7a) (7b) (7c) de la platine (7) de façon à immobiliser les deux pieds (5) orientables dans chacune des trois positions définies suivant la position des orifices de la platine (7). C'est ainsi que lorsque le verrou à ressort (6) est engagé dans l'orifice (7a), l'appareil de levage est en position repliée pour son transport ou son stockage comme en figure 4. Lorsqu'il est engagé dans l'orifice (7b), les pieds (5) orientables sont écartés au maximum conférant ainsi une bonne stabilité pour l'appareil de levage en utilisation et lorsqu'il est engagé dans l'orifice (7c), les deux pieds (5) orientables sont moins écartés de façon à permettre le passage de l'appareil dans les portes.Still according to FIGS. 1, 2, 4, 5, 7, 13 and 15, each of the two steerable legs (5) is provided with a spring latch (6) which engages in the orifices (7a) (7b). ) (7c) of the plate (7) so as to immobilize the two feet (5) orientable in each of the three positions defined according to the position of the orifices of the plate (7). Thus, when the spring latch (6) is engaged in the hole (7a), the hoist is in the folded position for transport or storage as in FIG. orifice (7b), the feet (5) are adjustable at the maximum distance thus providing good stability for the lifting device in use and when engaged in the orifice (7c), the two feet (5) orientable are less distant so as to allow the passage of the apparatus in the doors.

Suivant les figures 1, 2, 4, 5, 6, 7 et 13, le mât télescopique (2) est articulé (en 36) sur la platine (7) du piétement (1) et peut être verrouillé sur ce même piétement suivant deux positions : l'une dite de transport comme montré principalement par la figure 4 ; l'autre dite d'utilisation comme montré par les figures 1, 2, 7 et 13. La position dite de transport est obtenue à l'aide du verrou à ressort (8) qui s'engage automatiquement dans l'orifice (10) de la plaque (9) solidaire du pied (5a) fixe et d'un berceau support (39), également solidaire du pied (5a) fixe sur lequel le mât télescopique (2) replié vient prendre appui. Lorsque l'appareil est en utilisation, le mât télescopique (2) est maintenu dans sa position verticale au moyen du même verrou à ressort (8) alors engagé automatiquement dans l'orifice (12) du plat (11) solidaire de la platine (37) du piétement (1). Une pente est donnée avantageusement au plat (11) et à la plaque (9) de façon à assurer une entrée d'engagement au verrou à ressort (8) permettant un verrouillage automatique lors du passage de la position repliée à la position d'utilisation et vice-versa.According to Figures 1, 2, 4, 5, 6, 7 and 13, the telescopic mast (2) is articulated (36) on the plate (7) of the base (1) and can be locked on the same base following two positions: one called transport as shown mainly in Figure 4; the other said use as shown in Figures 1, 2, 7 and 13. The so-called transport position is obtained by means of the spring latch (8) which engages automatically in the orifice (10) the plate (9) secured to the fixed foot (5a) and a support cradle (39), also integral with the fixed foot (5a) on which the telescopic mast (2) folded bears. When the device is in use, the telescopic mast (2) is held in its vertical position by means of the same spring latch (8) then automatically engaged in the orifice (12) of the plate (11) integral with the plate ( 37) of the base (1). A slope is advantageously given to the plate (11) and to the plate (9) so as to ensure an engagement input to the spring lock (8) allowing automatic locking when changing from the folded position to the use position and vice versa.

Suivant les figures 1, 8 et 9, la base non télescopique (13) du mât (2) comporte le support (14) du treuil (15). Sur ce support est monté un verrou à ressort (16) guidé par un canon (17) solidaire du support (14). Comme montré principalement sur la figure 9, l'extrémité (19) du verrou à ressort (16) s'engage dans l'orifice (18) du support (14) et dans l'orifice (13a) de l'élément (13) du mât télescopique (2) puis dans les orifices (20) (21) (22) pratiqués respectivement dans les parties télescopiques (23) (24) (25) ; l'ensemble de ces orifices étant placés dans le même alignement lorsque les parties télescopiques du mât sont en position basse. Ce verrouillage permet d'obtenir un blocage total des différentes parties télescopiques du mât avec sa base non télescopique (13) de façon à solidariser l'ensemble et faciliter ainsi le transport ou les différentes manipulations de l'appareil de levage.According to Figures 1, 8 and 9, the non-telescopic base (13) of the mast (2) comprises the support (14) of the winch (15). On this support is mounted a spring lock (16) guided by a barrel (17) integral with the support (14). As shown mainly in FIG. 9, the end (19) of the spring latch (16) engages in the orifice (18) of the support (14) and in the orifice (13a) of the element (13). ) of the telescopic mast (2) then in the orifices (20) (21) (22) respectively formed in the telescopic parts (23) (24) (25); all of these orifices being placed in the same alignment when the telescopic parts of the mast are in the low position. This locking allows to obtain a total blocking of the various telescopic parts of the mast with its non-telescopic base (13) so as to secure the assembly and thus facilitate the transport or the various manipulations of the hoist.

Suivant les figures 1, 2, 4, 13 et 14, la platine (7) est équipée sur sa face inférieure d'un rouleau (26) qui a pour double fonction de protéger contre les chocs de la platine (7) les sols plus ou moins fragiles et de faciliter le roulement et par conséquent le déplacement de l'appareil de levage replié qui peut, par ailleurs, être aisément tiré par l'utilisateur en utilisant la tête (27) du mât télescopique (2).According to FIGS. 1, 2, 4, 13 and 14, the plate (7) is equipped on its underside with a roller (26) which has the dual function of protecting against impacts of the plate (7) the more or less fragile and facilitate the rolling and therefore the displacement of the folded hoist which can, moreover, be easily pulled by the user using the head (27) of the telescopic mast (2).

Suivant la figure 3, une pièce (40) en forme de U renversé du pupitre support de plaque amovible (3) vient coiffer la tête (27) qui termine le haut du mât télescopique (2).According to FIG. 3, an inverted U-shaped part (40) of the removable plate support plate (3) caps the head (27) which terminates the top of the telescopic mast (2).

Suivant les figures 1, 10, 11 et 12, le pupitre support de plaque amovible (3) ainsi positionné, doit pouvoir être utilisé soit horizontalement, soit incliné à des degrés divers, de façon à s'adapter aux différentes pentes des plafonds à équiper de plaques. Ce réglage de la position du pupitre est obtenu au moyen d'une poignée mobile (28) qui vient en butée sur la languette (43) du pupitre support de plaque amovible (3) et guidée dans son déplacement entre deux ouvertures (29) (30) de forme circulaire, pratiquées respectivement dans les deux flasques (31) (32) solidaires de la tête (27) du mât télescopique (2). Le maintien en position désirée est obtenu par serrage de ladite poignée mobile (28) au moyen d'un blocage à serrage rapide par excentrique constitué d'un axe-vis (33) comportant, à son extrémité filetée, un écrou (34) et à son autre extrémité, une manette à excentrique (35). L'écrou (34) permet d'obtenir, en le vissant ou en le dévissant, un serrage plus ou moins fort de la poignée mobile (28) entre les flasques (31) (32) sous l'effet de la manette à excentrique (35).According to FIGS. 1, 10, 11 and 12, the removable plate support panel (3) thus positioned must be able to be used either horizontally or inclined to varying degrees, so as to adapt to the different slopes of the ceilings to be fitted. of plates. This adjustment of the position of the desk is obtained by means of a movable handle (28) which comes into abutment on the tongue (43) of the removable plate support panel (3) and guided in its displacement between two openings (29) (30) of circular shape, made respectively in the two flanges (31) (32) integral with the head (27) of the telescopic mast (2). Maintaining the desired position is obtained by clamping said movable handle (28) by means of an eccentric quick-clamping block consisting of a screw shaft (33) having, at its threaded end, a nut (34) and at its other end, an eccentric lever (35). The nut (34) makes it possible to obtain, by screwing or unscrewing it, a more or less strong clamping of the movable handle (28) between the flanges (31) (32) under the effect of the eccentric lever (35).
