Description

L'invention se rattache au secteur technique des appareils de levage et de manutention utilisables notamment dans le bâtiment.The invention relates to the technical sector of lifting devices and handling usable especially in the building.

Il existe différents appareils destinés à élever des plaques ou panneaux en plâtre ou autres matériaux, de grandes dimensions et de poids élevé, depuis une hauteur accessible à l'utilisateur placé au sol jusqu'à proximité des plafonds, que l'on doit revêtir en vue de réaliser des faux-plafonds ou encore des isolations phoniques ou thermiques.There are different devices for raising plates or plaster or other material panels, large and heavy high, from a height accessible to the user placed on the ground up to proximity to ceilings, which must be clad in order to create false ceilings or even phonic or thermal insulation.

Un appareil de levage de ce type a par exemple été décrit dans le brevet français 2.538.437. Il comprend, à partir d'un piétement roulant un mât en plusieurs éléments télescopiques manoeuvrés par un ensemble câble-poulie, mouflés et actionnés par un treuil. L'extrémité supérieure dudit mât est agencée pour recevoir un plateau porte-matériau ou porte-plaques. L'appareil est agencé avec un dispositif de sécurité évitant la descente brutale du plateau en cas de rupture de câble.A lifting device of this type has for example been described in the French patent 2,538,437. It includes, from a rolling base a mast made of several telescopic elements operated by a cable-pulley assembly, hauled up and operated by a winch. The upper end of said mast is arranged to receive a material-holding plate or plate-holder. The device is arranged with a safety device preventing descent abrupt plateau due to cable break.

Le Demandeur a développé un dispositif de sécurité amélioré audit appareil de levage de plaques pour répondre à certains inconvénients de l'art antérieur défini par le brevet français 2.538.437 précité. En particulier, ces inconvénients résultaient de certains effets de coincement du dispositif de sécurité et des moyens qui lui étaient associés. The Applicant has developed an improved security system for auditing plate lifting device to meet certain disadvantages of the art earlier defined by the aforementioned French patent 2,538,437. In particular, these disadvantages resulted from certain jamming effects of the security and the means associated with it.

Le Demandeur a ainsi proposé, dans le brevet français 2 758 150, un dispositif constitué par un double mouflage des colonnes fixes ou coulissantes du mât incluant un treuil agencé pour enrouler ou dérouler séparément deux câbles, des ensembles de renvoi pour les deux câbles indépendamment et des points d'ancrage des câbles distincts et décalés pour chacun d'eux, de manière à ce que l'un des câbles appelés "câble de traction" supporte seul la charge à déplacer dans les conditions normales de fonctionnement, tandis que l'autre câble dit "câble de sécurité" intervient en substitution, en cas de rupture du premier. La mise en oeuvre du fonctionnement de l'appareil s'effectue à l'aide d'un treuil à tambour avec deux gorges, le treuil étant manoeuvrable manuellement par une poignée.The Applicant thus proposed, in the French patent 2 758 150, a device consisting of a double hauling of the fixed columns or sliding of the mast including a winch arranged to wind or unwind two cables separately, return sets for the two cables independently and separate and offset cable anchor points for each of them, so that one of the cables called "pull cable" only supports the load to be moved under normal conditions of operation, while the other cable called "safety cable" intervenes in substitution, in the event of rupture of the first. The implementation of the appliance is operated using a drum winch with two grooves, the winch being manually operable by a handle.

Si la fiabilité du dispositif de sécurité ainsi rappelé est établi, par contre la manipulation manuelle de l'appareil est peu pratique.If the reliability of the safety device thus recalled is established, by against manual manipulation of the device is impractical.

Le but recherché selon l'invention était donc de concevoir un appareil de levage et de manutention pour la pose de plaques au plafond qui soit à la fois utilisable et manoeuvrable rapidement et sans effort, tout en lui assurant les critères de sécurité rappelés précédemment.The aim sought after according to the invention was therefore to design an apparatus of lifting and handling for the installation of plates on the ceiling which is at the both usable and maneuverable quickly and effortlessly, while ensuring the security criteria recalled above.

Un autre but recherché selon l'invention était de concevoir un appareil de levage et de manutention des plaques avec un grand confort d'utilisation par l'opérateur.Another object sought after according to the invention was to design a device for lifting and handling plates with great comfort of use by the operator.

Selon une première caractéristique de l'invention, l'appareil de levage et de manutention de plaques de matériau destinés notamment à la couverture de plafond du type comprenant à partir d'un piétement roulant un mât en plusieurs éléments télescopiques manoeuvrés par un moyen de commande, l'extrémité supérieure dudit mât étant agencée pour recevoir un plateau porte-matériau ou porte-plaques, l'appareil étant agencé avec un dispositif de sécurité évitant la descente brutale du plateau en cas de rupture de câble, caractérisé en ce que l'appareil comprend une structure portante verticale agencé pour recevoir, d'une manière fixe, la colonne inférieure du mât télescopique, et une plate-forme support d'un bloc moteur,
et en ce que ledit bloc moteur est associé par son arbre de sortie à une vis sans fin disposée verticalement et guidée à l'intérieur du mât télescopique,
et en ce que la vis sans fin est accouplée à un palier écrou solidaire de l'élément intermédiaire mobile du mât télescopique,
et en ce que un élément supérieur du mât est susceptible de s'engager dans l'élément intermédiaire,
et en ce que la mise en fonctionnement du bloc moteur entraíne la rotation de la vis sans fin et le déplacement linéaire vertical du palier écrou entraínant le déplacement de l'élément intermédiaire du mât, puis de l'élément supérieur,
et en ce que des câbles de travail et de sécurité sont solidarisés auxdits éléments télescopiques du mât et à la structure portante pour assurer et contrôler lesdits déplacements des éléments mobiles du mât.According to a first characteristic of the invention, the device for lifting and handling sheets of material intended in particular for covering the ceiling of the type comprising, from a rolling base, a mast made of several telescopic elements maneuvered by a control means , the upper end of said mast being arranged to receive a material-carrying plate or plate holder, the apparatus being arranged with a safety device preventing the abrupt descent of the plate in the event of cable breakage, characterized in that the apparatus comprises a vertical supporting structure arranged to receive, in a fixed manner, the lower column of the telescopic mast, and a platform supporting a motor unit,
and in that said engine block is associated by its output shaft with an endless screw arranged vertically and guided inside the telescopic mast,
and in that the worm is coupled to a nut bearing secured to the movable intermediate element of the telescopic mast,
and in that an upper element of the mast is capable of engaging in the intermediate element,
and in that the operation of the engine block causes the rotation of the worm and the vertical linear displacement of the nut bearing causing the displacement of the intermediate element of the mast, then of the upper element,
and in that working and safety cables are secured to said telescopic elements of the mast and to the supporting structure to ensure and control said movements of the mobile elements of the mast.

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle :The advantages are apparent from the description, in particular one underline and remind:

L'appareil et de manutention permettant la pose de plaques ou panneaux (2) de grandes dimensions et référencé dans son ensemble par (1).The device and handling allowing the installation of plates or large panels (2) and referenced as a whole by (1).

Il comprend une structure portante verticale (3) formant colonne agencée dans sa partie inférieure pour recevoir un piétement (4) articulé incluant par exemple quatre bras articulés (5) montés sur des moyens de roulement (6). Lesdits bras (5) sont solidaires de la structure portante par des bridages appropriés et sont destinés à être pivotés pour permettre leur rabattement entre eux, lors de la non utilisation de l'appareil. La structure portante agencée pour recevoir une poignée de manoeuvre (7) pouvant être saisie par l'opérateur. Ladite structure présente, à sa base, des moyens de roulement (8) complémentaires, permettant de déplacer l'appareil en situation pliée, comme représenté figure 1.It includes a vertical supporting structure (3) forming a column arranged in its lower part to receive an articulated base (4) including for example four articulated arms (5) mounted on means of bearing (6). Said arms (5) are integral with the supporting structure by appropriate clamps and are intended to be pivoted to allow their drawdown between them, when the device is not in use. The structure bearing designed to receive an operating handle (7) which can be entered by the operator. Said structure has, at its base, means for bearing (8) complementary, allowing to move the device in folded situation, as shown in figure 1.

Le long de la structure portante est disposé et accolé une colonne fixe (9a) constituant l'élément inférieur du mât télescopique (9) de l'appareil.Along the supporting structure is arranged and attached a fixed column (9a) constituting the lower element of the telescopic mast (9) of the device.

Adjacent à la structure portante et à la colonne fixe (9a), est disposée une plate-forme support (10) d'un bloc moteur (11) avec carter de protection (24). L'arbre de sortie (11a) dudit bloc moteur est accouplé par un ensemble de poulies de renvoi (12) à une vis sans fin (13) disposée verticalement et guidée à l'intérieur du mât télescopique, ainsi qu'il sera précisé par la suite. Le bloc moteur (11) est du type monophasé ou triphasé, et il est commandé en fonctionnement par une commande électrique (14) établie de toute manière connue et pouvant être par exemple "à distance" avec ou sans cordon de liaison. Le guidage des moyens de transmission est établi de toute manière appropriée et connue.Adjacent to the supporting structure and the fixed column (9a), is arranged a support platform (10) of an engine block (11) with protective casing (24). The output shaft (11a) of said engine block is coupled by an assembly return pulleys (12) to a worm (13) arranged vertically and guided inside the telescopic mast, as will be explained later. The motor unit (11) is of the single-phase or three-phase type, and it is controlled in operation by an electrical control (14) established from any known manner and can be for example "remote" with or without connecting cord. The guidance of the transmission means is established in an appropriate and known manner.

La colonne fixe (9a) est fixée par soudure ou autrement à la structure portante. Dans sa partie supérieure, la colonne fixe constituant l'élément inférieur est agencée pour recevoir un moyen d'ancrage (15) d'un couple de câble (16 - 17), l'un de tension (16), l'autre de sécurité (17).The fixed column (9a) is fixed by welding or otherwise to the structure bearing. In its upper part, the fixed column constituting the element lower is arranged to receive an anchoring means (15) of a couple of cable (16 - 17), one of tension (16), the other of safety (17).

Le mât télescopique (9) comprend deux éléments complémentaires (9b - 9c) susceptibles de s'engager l'un dans l'autre et l'ensemble (9b - 9c) dans l'élément inférieur (9a) précité. The telescopic mast (9) comprises two complementary elements (9b - 9c) likely to engage one with the other and the whole (9b - 9c) in the aforementioned lower element (9a).

Selon l'invention, l'élément intermédiaire (9b) est accouplé à au moins un palier (18) formant écrou disposé sur la vis de manoeuvre (13). Ce palier est profilé et solidarisé à l'élément intermédiaire (9b), d'une manière fixe, de manière à permettre son déplacement vertical de haut en bas ou de bas en haut, selon le mode de commande de la motorisation précitée. Ledit élément intermédiaire (9b) est guidé à l'intérieur de la colonne fixe (9a) à l'aide de moyens connus du type patins (20) ou similaires. La partie supérieure (9c) de l'élément intermédiaire (9b) est agencée pour recevoir des moyens de renvoi (21) des deux câbles (16 et 17) précités.According to the invention, the intermediate element (9b) is coupled to the at least one bearing (18) forming a nut arranged on the operating screw (13). This bearing is profiled and secured to the intermediate element (9b), in a way fixed, so that it can be moved vertically up and down or bottom to top, depending on the control mode of the above-mentioned engine. said intermediate element (9b) is guided inside the fixed column (9a) at using known means of the shoe type (20) or the like. The part upper part (9c) of the intermediate element (9b) is arranged to receive return means (21) of the aforementioned two cables (16 and 17).

L'élément supérieur (9c) du mât (9) est susceptible de s'engager à l'intérieur de l'élément intermédiaire (9b) et peut se déplacer par rapport à lui. L'élément supérieur (9c) comprend, à sa base, des moyens d'ancrage (22) des câbles de travail et de sécurité. L'extrémité supérieure dudit élément est agencée pour recevoir, d'une manière connue, la plate-forme réceptrice (23) des panneaux (2) destinés à être posés au plafond.The upper element (9c) of the mast (9) is capable of committing to inside the intermediate element (9b) and can move relative to him. The upper element (9c) comprises, at its base, anchoring means (22) work and safety cables. The upper end of said element is arranged to receive, in a known manner, the platform receiving (23) panels (2) intended to be installed on the ceiling.

Ainsi, lors de l'actionnement du moteur de commande, la vis sans fin (13) est mise en rotation. Elle entraíne de ce fait le déplacement linéaire vertical du palier écrou (18) qui lui est associé entraínant le déplacement correspondant de la colonne intermédiaire (9b). Dans son déplacement, la colonne intermédiaire (9b) exerce un effort sur le câble (16) de travail qui est fixé à la structure portante et au bas de la colonne supérieure (9c) du mât, ce qui permet un déplacement de cette dernière.Thus, when the control motor is actuated, the worm (13) is rotated. It therefore causes linear displacement vertical of the nut bearing (18) associated therewith causing the displacement correspondent of the intermediate column (9b). In its displacement, the intermediate column (9b) exerts a force on the working cable (16) which is attached to the supporting structure and to the bottom of the upper column (9c) of the mast, which allows a displacement of the latter.

Pour assurer un contrôle de la course de déplacement des colonnes mobiles (9b - 9c), il est prévu de disposer des moyens de butée (25 - 26) formant fin de course dans les positions haute et basse de la colonne intermédiaire (9b). Ces fins de course (25 - 26) sont disposés et fixés à partir de la structure portante, ou de la colonne fixe, et débouchent dans l'espace formé entre la colonne fixe (9a) du mât et la colonne intermédiaire (9b). Un moyen de butée (27) fixé extérieurement en saillie sur la colonne intermédiaire (9b) est susceptible de venir en contact avec le ou les fins de course (25 - 26) en limitant ainsi ledit déplacement des éléments télescopiques du mât.To control the travel of the columns mobile (9b - 9c), it is planned to have stop means (25 - 26) forming limit switch in the upper and lower positions of the column intermediate (9b). These limit switches (25 - 26) are arranged and fixed to from the supporting structure, or from the fixed column, and lead into the space formed between the fixed column (9a) of the mast and the intermediate column (9b). A stop means (27) fixed externally projecting from the column intermediate (9b) is likely to come into contact with the end (s) of stroke (25 - 26) thereby limiting said displacement of the elements telescopic mast.

Afin d'assurer une plus grande sécurité de l'appareil de levage précité, il est prévu d'adjoindre des moyens de sécurité. Une première sécurité consiste à la mise en place du câble (17) qui est susceptible de se substituer au câble de travail (16) en cas de rupture de ce dernier.To ensure greater safety of the lifting device mentioned above, it is planned to add security means. A first security consists in the installation of the cable (17) which is likely to be replace the working cable (16) if it breaks.

Sur la commande vis sans fin - palier écrou, on dispose un écrou de sécurité (28) supplémentaire fixé sur la vis sans fin (13) et en dessous du palier écrou associé .à la colonne intermédiaire (9b).On the worm screw - nut bearing order, there is a additional safety (28) fixed on the worm (13) and below the nut bearing associated with the intermediate column (9b).

Ce palier écrou est avantageusement en bronze. Après un usage intensif, son filetage intérieur peut disparaítre pouvant entraíner la chute de la charge. L'écrou de sécurité (28) est ainsi disposé sous le palier écrou à un intervalle (h) correspondant à un jeu de sécurité. En cas de détérioration du palier écrou en bronze, la colonne intermédiaire (9b) peut se déplacer verticalement vers le bas en venant en butée sur l'écrou de sécurité (28) et en actionnant, par une butée supérieure (29), l'interrupteur de fin de course (25). This nut bearing is advantageously made of bronze. After one use intensive, its internal thread may disappear which may cause the fall of load. The safety nut (28) is thus placed under the nut bearing at a interval (h) corresponding to a safety game. In case of deterioration of the bronze nut bearing, the intermediate column (9b) can move vertically downwards in abutment on the safety nut (28) and by actuating, by an upper stop (29), the limit switch (25).

Ainsi, selon l'invention, l'appareil de levage est entièrement motorisé et d'utilisation sans peine pour l'opérateur. La commande de la vis sans fin filetée assure un déplacement progressif et constant de l'élément intermédiaire (9b) puis de l'élément supérieur (9c). Le guidage de la vis sans fin est parfaitement contrôlé à l'intérieur de la colonne intermédiaire (9b). Il peut être envisagé, si besoin est, en fonction de la longueur de la vis, de disposer un deuxième palier de guidage qui serait fixé à la colonne intermédiaire.Thus, according to the invention, the lifting device is fully motorized and ease of use for the operator. The worm control threaded ensures progressive and constant movement of the element intermediate (9b) then of the upper element (9c). The guidance of the screw without end is perfectly controlled inside the intermediate column (9b). he can be considered, if necessary, depending on the length of the screw, have a second guide bearing which would be fixed to the column intermediate.

L'appareil de levage et de manutention de plaques de grandes dimensions, est particulièrement performant en ce qu'il permet un réglage très précis dans l'approche et la présentation des plaques au plafond ou panneaux au plafond ou sur la zone à revêtir.The device for lifting and handling large plates dimensions, is particularly efficient in that it allows adjustment very precise in the approach and presentation of the ceiling plates or panels on the ceiling or on the area to be coated.

L'appareil est d'une manipulation aisée et d'un faible encombrement puisque le mât peut s'escamoter à l'intérieur de son élément fixe, et que certains bras du piétement peuvent être pivotés et rapprochés dans un même plan. Les moyens de roulement solidaires de la structure portante permettent un déplacement de l'appareil, la poignée de préhension solidaire de la structure constituant la poignée de tirage de l'appareil.The device is easy to handle and takes up little space since the mast can retract inside its fixed element, and that certain legs of the base can be swiveled and brought together in the same plan. The rolling means integral with the bearing structure allow a movement of the device, the grip handle integral with the structure constituting the pull handle of the device.

Le bloc moteur est protégé dans un carter approprié (24). Ce bloc moteur est choisi pour correspondre aux besoins de l'appareil et notamment dans la puissance et vitesse d'élévation du mât télescopique.The engine block is protected in a suitable housing (24). This block motor is chosen to correspond to the needs of the device and in particular in the power and speed of elevation of the telescopic mast.

On précise également que le piétement comprenant quatre bras permet un positionnement en alignement deux à deux de ceux-ci, permettant le positionnement de plates-formes (30) d'appui sur les chants supérieurs des bras et permettant ainsi à l'opérateur de se positionner sur l'appareil, pour faciliter le travail de pose des plaques.It is also specified that the base comprising four arms allows positioning in alignment two by two of these, allowing positioning of platforms (30) for support on the upper edges arms and thus allowing the operator to position himself on the device, to facilitate the work of laying the plates.

Pour assurer un grand confort d'utilisation et de sécurité, lesdits éléments constitutifs du mât télescopique sont guidés par les patins précités permettant un meilleur guidage notamment pour le rattrapage des jeux, un glissement en douceur et sans bruit, et une meilleure stabilité de la plaque ou panneau à poser, quand lesdites colonnes sont déployées au maximum.To ensure great comfort in use and safety, said constituent elements of the telescopic mast are guided by the aforementioned pads allowing better guidance especially for catching up on games, a smooth, noise-free sliding and better plate stability or panel to be installed, when said columns are deployed to the maximum.

La charge utile permise par l'appareil de levage selon l'invention est de l'ordre de 100 kilogrammes, à une hauteur de 4 mètres, ce qu'aucun appareil existant sur le marché ne peut proposer.The payload allowed by the lifting device according to the invention is of the order of 100 kilograms, at a height of 4 meters, which none existing device on the market can not offer.
