Abstract

The cutter (1) consists of a frame with a cutting table (2) that has a lengthwise slot (3) for a blade (4) mounted on a carriage (5) guided over the slot. The carriage is moved by a pair of handles (6, 7) in a single inverted V-shaped configuration that allows the cutter to be used by a right- or left-handed person. The grip sections (6A, 7A) of the handles intersect a plane passing through the cutting blade and slot, and have their centres of gravity in line with the slot. The handle branches (6B, 7B) connecting the grip sections to the blade holder are inclined relative to the plane of the blade.

Description

La présente invention concerne un appareil pour le tranchage de matériaux en plaque, tels qu'ardoise, carrelage, vitre ou carreau.The present invention relates to an apparatus for cutting materials in plate, such as slate, tile, glass or tile.

Elle concerne plus particulièrement un appareil, pour le tranchage de matériaux en plaque, du type comprenant, au moins un bâti incorporant une table de coupe délimitant une fente longitudinale parcourue par une lame de coupe, généralement circulaire, et montée libre à rotation sur un chariot guidé au-dessus de la fente et manoeuvré par une poignée de saisie.It relates more particularly to an apparatus, for slicing materials in plate, of the type comprising, at least one frame incorporating a table cutting delimiting a longitudinal slot traversed by a cutting blade, generally circular, and mounted free to rotate on a carriage guided above from the slot and operated by a grip.

De tels appareils sont bien connus à ceux versés dans cet art. L'opération de tranchage s'effectue par manoeuvre manuelle du chariot tenu par une main de l'opérateur tandis que l'autre main de l'opérateur sert au maintien de l'ardoise sur la table de coupe. L'opérateur est généralement placé à une extrémité de la table de coupe et effectue l'opération de tranchage en déplaçant dans sa direction le chariot muni de la lame de coupe. Jusqu'à présent, les appareils pour le tranchage de matériaux en plaque du type précité sont munis soit d'une poignée unique de manoeuvre du chariot, cette poignée s'étendant perpendiculairement à l'axe de déplacement en va-et-vient du chariot, comme l'illustrent les brevets FR-A-2.528.348 et FR-A-2.497.533, soit de deux poignées dont les parties de saisie disposées de part et d'autre des axes de déplacement du chariot en s'étendant parallèlement à ce dernier comme l'illustre le brevet FR-A-2.414.391. Dans les deux configurations décrites ci-dessus, la position occupée par l'ensemble main/avant-bras de l'opérateur lors de la manoeuvre du chariot est soit une position inconfortable, soit une position qui oblige l'opérateur de fournir un effort musculaire important pour permettre la manoeuvre dudit chariot. Dans le cas du brevet FR-A-2.414.391, les deux poignées sont utilisées simultanément, l'une était saisie par la main gauche, l'autre par la main droite. Comme les parties de saisie de ces poignées s'étendent parallèlement au plan passant par la lame de coupe et de part et d'autre de ce plan, les mains de l'utilisateur s'étendant en position de saisie de part et d'autre du plan passant par la lame de coupe avec les paumes de main en regard.Such devices are well known to those versed in this art. The operation of slicing is carried out by manual operation of the carriage held by a hand of the operator while the other hand of the operator is used to maintain the slate on the cutting table. The operator is usually placed at one end of the cutting table and performs the slicing operation by moving in its towards the carriage fitted with the cutting blade. So far, the devices for slicing plate materials of the aforementioned type are provided with either a single handle for maneuvering the carriage, this handle extending perpendicular to the axis of reciprocating movement of the carriage, as illustrate it by patents FR-A-2,528,348 and FR-A-2,497,533, that is to say two handles with gripping parts arranged on either side of the axes of movement of the carriage extending parallel to it as illustrated by patent FR-A-2,414,391. In the two configurations described above, the position occupied by the operator's hand / forearm assembly when of the cart maneuver is either an uncomfortable position or a position which requires the operator to provide significant muscular effort to allow the operation of said carriage. In the case of patent FR-A-2,414,391, the two handles are used simultaneously, one was grasped by the left hand, the other by the right hand. Like the grip parts of these handles extend parallel to the plane passing through the cutting blade and share and on the other side of this plane, the user's hands extending into the gripping position of on either side of the plane passing through the cutting blade with the palms of the hand opposite.

Un but de la présente invention est donc de proposer un appareil pour le tranchage de matériaux en plaque dont la conception optimisée de la poignée de saisie permet d'une part de limiter l'effort musculaire devant être fourni par l'opérateur pour trancher ledit matériau, d'autre part de permettre à l'ensemble main/avant-bras de cet opérateur d'occuper une position correspondant à une position naturelle de repos, cette position reproduisant au mieux le mouvement naturellement suivi par l'ensemble bras/main lors d'une opération de tranchage.An object of the present invention is therefore to propose an apparatus for slicing of plate materials including optimized handle design on the one hand allows to limit the muscular effort to be provided by the operator to slice said material, on the other hand to allow the whole hand / forearm of this operator to occupy a position corresponding to a natural rest position, this position best reproducing the movement naturally followed by the arm / hand assembly during a slicing operation.

A cet effet, l'invention a pour objet un appareil pour le tranchage de matériaux en plaque, tels qu'ardoise, carrelage, vitre ou carreau, du type comprenant au moins un bâti incorporant une table de coupe délimitant une fente longitudinale parcourue par une lame de coupe montée sur un chariot guidé au-dessus de la fente et manoeuvré par une poignée de saisie, caractérisé en ce que le chariot comporte deux poignées dont les parties de saisie s'inscrivent dans un V de manière telle qu'elles puissent être utilisées alternativement par un gaucher ou un droitier, les parties de saisie de ces poignées coupant le plan passant par la lame de coupe et la fente de circulation de la lame de coupe de manière telle que la main, en position de saisie de la poignée, occupe avec le bras une position correspondant à la position naturelle de repos exempte de contraintes de rotation interne et de rotation externe liées à une pronation et/ou à une supination.To this end, the invention relates to an apparatus for slicing materials in a plate, such as slate, tile, glass or tile, of the type comprising minus a frame incorporating a cutting table delimiting a longitudinal slot traversed by a cutting blade mounted on a carriage guided above the slot and operated by a grip handle, characterized in that the carriage has two handles, the grip parts of which are written in a V of in such a way that they can be used alternately by a left-hander or right-handed, the grip parts of these handles cutting the plane passing through the cutting blade and the cutting blade circulation slot in such a way that the hand, in the grip position of the handle, occupies with the arm a position corresponding to the natural resting position free of constraints internal rotation and external rotation related to pronation and / or supination.

Grâce à la position relative de chacune des parties de saisie des poignées par rapport au plan passant par la lame de coupe et la fente de circulation de la lame de coupe, il en résulte la possibilité pour la main et le bras de l'opérateur d'occuper, pendant toute l'opération de tranchage, une position correspondant à une position naturelle de repos de l'ensemble, c'est-à-dire une position dans laquelle toute contrainte liée à une pronation et/ou à une supination est supprimée. La partie de saisie de chaque poignée s'étend ainsi de part et d'autre du plan passant par la lame de coupe et au-dessus de la lame de coupe.Thanks to the relative position of each of the gripping parts of the handles by relative to the plane passing through the cutting blade and the circulation slot of the cutting blade, this results in the possibility for the operator's hand and arm to occupy, during the whole slicing operation, a corresponding position to a natural rest position of the whole, i.e. a position in which any constraint related to pronation and / or supination is deleted. The grip portion of each handle thus extends on both sides and across the plane passing through the cutting blade and above the cutting blade chopped off.

L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels :

  • la figure 1 représente une vue en perspective d'un mode de réalisation d'un appareil pour le tranchage de matériaux en plaque conforme à l'invention ;

  • la figure 4 représente une vue en coupe de l'ensemble poignée/chariot et
  • la figure 5 représente une vue schématique partielle de face de l'ensemble poignée/chariot.
    • The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:
  • Figure 1 shows a perspective view of an embodiment of an apparatus for slicing plate materials according to the invention;
  • Figure 2 shows a three quarter front view of a handle and a carriage according to the invention;
  • Figure 3 shows a top view of the handle / carriage assembly shown in Figure 2;
  • FIG. 4 represents a sectional view of the handle / carriage assembly and
  • FIG. 5 represents a partial schematic front view of the handle / carriage assembly.

    • Comme mentionné ci-dessus, l'appareil 1, objet de l'invention, est destiné au tranchage de matériaux en plaque, tels qu'ardoise, carrelage, vitre ou similaire. Cet appareil 1 comprend au moins un bâti 9 incorporant une table 2 de coupe délimitant une fente 3 longitudinale parcourue par une lame 4 de coupe montée sur un chariot 5 guidé au-dessus de la fente 3 et manoeuvré par une poignée 6, 7 de saisie. Dans les exemples représentés, le bâti 9 est un bâti métallique présentant une platine destinée à la réalisation de la table 2 de coupe, cette table 2 de coupe étant surmontée de deux longerons 10 affectant par exemple la forme de profilés en U et constituant en particulier des surfaces d'appui pour le déplacement d'éléments de guidage, tels que des galets, équipant le chariot 5. Dans les exemples représentés, le chariot 5 est équipé de deux séries de galets 13, la première série enserrant une branche horizontale du longeron en forme de U, tandis qu'une seconde série de galets vient en appui sur une arête de la branche du U. Les deux longerons 10 sont reliés à chacune de leurs extrémités par des traverses 11 servant à la finalisation du bâti 2.As mentioned above, the device 1, object of the invention, is intended for slicing of sheet materials, such as slate, tiles, glass or the like. This device 1 comprises at least one frame 9 incorporating a cutting table 2 delimiting a longitudinal slot 3 traversed by a mounted cutting blade 4 on a carriage 5 guided above the slot 3 and maneuvered by a handle 6, 7 input. In the examples shown, the frame 9 is a metal frame having a plate intended for the production of the cutting table 2, this 2 cutting table being surmounted by two side members 10 affecting for example the shape of U-shaped profiles and constituting in particular bearing surfaces for the displacement of guide elements, such as rollers, fitted to the carriage 5. In the examples shown, the carriage 5 is equipped with two series of rollers 13, the first series enclosing a horizontal branch of the spar in U-shaped, while a second series of rollers comes to rest on an edge of the U branch. The two longitudinal members 10 are connected to each of their ends by crosspieces 11 used to finalize the frame 2.

    La table 2 de coupe comporte une fente 3 longitudinale parcourue par une lame 4 de coupe constituée ici par une lame circulaire montée libre à rotation à l'intérieur du corps du chariot 5. Ce chariot 5, guidé au-dessus de la fente 3 par les galets 13 mentionnés ci-dessus, est manoeuvré par une poignée 6, 7 de saisie. Dans les exemples représentés, le chariot 5 comporte deux poignées de saisie représentées en 6 et 7 aux figures. Les parties 6A, 7A de saisie de ces poignées s'inscrivent dans un V de manière telle qu'elles puissent être utilisées alternativement par un gaucher ou un droitier. Ainsi, la poignée représentée en 6 aux figures est destinée à un droitier tandis que la poignée représentée en 7 est destinée à un gaucher, l'opérateur étant à chaque fois placé à une extrémité de la table 2 de coupe et déplaçant le chariot en le manoeuvrant dans une direction tendant à le rapprocher de l'utilisateur. Ainsi, dans l'exemple représenté à la figure 1, l'opérateur droitier saisira la poignée 6 et se positionnera à l'extrémité de gauche de la table de coupe tandis que l'opérateur gaucher saisira la poignée 7 et se positionnera à l'extrémité de droite de la table de coupe. L'opérateur tendra, au cours de l'opération de tranchage, de rapprocher le chariot de lui. Ces poignées peuvent être écartées l'une de l'autre de manière à constituer exclusivement une branche du V ou être réunies par une liaison constituant la pointe du V.The cutting table 2 has a longitudinal slot 3 traversed by a cutting blade 4 constituted here by a circular blade mounted free to rotate at inside the body of the carriage 5. This carriage 5, guided above the slot 3 by the rollers 13 mentioned above, is operated by a handle 6, 7 of capture. In the examples shown, the carriage 5 has two handles seizure shown in 6 and 7 in the figures. Parts 6A, 7A for entering these handles fit in a V so that they can be used alternatively by a left-handed or a right-handed person. Thus, the handle shown in 6 in the figures is intended for a right-handed person while the handle shown in 7 is intended for a left-handed person, the operator being each time placed end of the cutting table 2 and moving the carriage by maneuvering it in a direction tending to bring it closer to the user. So in the example shown in Figure 1, the right-handed operator will grab the handle 6 and will position at the left end of the cutting table while the operator left-handed person will grab handle 7 and position himself at the right end of the cutting table. The operator will tend, during the slicing operation, to move the cart closer to it. These handles can be moved away from each other so as to exclusively constitute a branch of V or to be united by a link constituting the point of V.

    Pour optimiser la position de l'ensemble main/bras de l'opérateur, les parties 6A, 7A de saisie de ces poignées coupent le plan passant par la lame 4 de coupe et la fente 3 de circulation de la lame 4 de coupe comme l'illustre la figure 3 où le plan a été représenté par une ligne XX'. Chaque partie 6A, 7A de saisie s'étend ainsi de chaque côté dudit plan au-dessus de la lame 4 de coupe. En effet, chaque partie de saisie comporte au moins une de ses portions s'étendant à l'aplomb de la fente 3 longitudinale. Ainsi, la main, en position de saisie de la poignée 6, 7, occupe avec le bras une position correspondant à la position naturelle de repos de cet ensemble, position dans laquelle le bras et la main sont exempts de contrainte de rotation interne et de rotation externe correspondant à une pronation et/ou à une supination de l'avant-bras. Dans cette position, la paume de la main s'étend sensiblement perpendiculairement au plan de la table de coupe.To optimize the position of the operator's hand / arm assembly, the parts 6A, 7A for gripping these handles cut the plane passing through the blade 4 of cutting and the slot 3 for circulation of the cutting blade 4 as illustrated in Figure 3 where the plane has been represented by a line XX '. Each part 6A, 7A of seizure thus extends on each side of said plane above the blade 4 of chopped off. Indeed, each entry part includes at least one of its portions extending perpendicular to the longitudinal slot 3. So the hand, in handle grip position 6, 7, occupies a position with the arm corresponding to the natural rest position of this set, position in arm and hand are free from internal rotation stress and external rotation corresponding to a pronation and / or a supination of the forearm. In this position, the palm of the hand extends substantially perpendicular to the plane of the cutting table.

    Pour parfaire cet équilibre, le centre de gravité de la partie 6A, 7A de saisie de la poignée 6, 7 s'étend sensiblement à l'aplomb de la fente 3 longitudinale de circulation de la lame 4 de coupe. Cette partie de saisie 6A ou respectivement 7A est renflée dans sa zone médiane pour faciliter sa préhension. Il est à noter que par centre de gravité, on entend le point central d'application des forces exercées par la main de l'utilisateur pour déplacer le chariot.To perfect this balance, the center of gravity of part 6A, 7A of the handle 6, 7 extends substantially in line with the longitudinal slot 3 of circulation of the cutting blade 4. This input part 6A or respectively 7A is swollen in its central zone to facilitate its gripping. Note that by center of gravity is meant the central point of application of the forces exerted by the user's hand to move the cart.

    Comme l'illustrent les figures, les branches 6B, 7B de la poignée 6, 7, qui assurent la liaison entre partie 6A ou 7A de saisie et chariot 5, sont inclinées par rapport au plan passant par la lame 4 de coupe pour entraíner un décalage correspondant des parties 6A, 7A de saisie des poignées 6, 7. Généralement, les parties 6A, 7A de saisie des poignées 6, 7 forment, avec le plan de la lame de coupe, un angle δ compris dans la plage [15 - 60] degrés, de préférence voisin de 30 degrés. Comme mentionné ci-dessus, les poignées 6, 7 portées par le chariot 5 peuvent être distinctes l'une de l'autre ou réalisées à contact jointif. Tel est le cas dans les exemples représentés. Ainsi, les poignées 6, 7 forment alors un ensemble monobloc affectant la forme d'un pont à pilier 8 central. Le sommet du pilier 8 constitue un point d'appui anti-rotation au pouce de l'utilisateur. Les parties 6A, 7A de saisie des poignées s'inscrivant dans un V forment entre elles un angle β compris dans la plage [100 - 140] degrés, de préférence voisin de 120 degrés.As illustrated in the figures, the branches 6B, 7B of the handle 6, 7, which ensure the connection between part 6A or 7A of gripping and carriage 5, are inclined relative to the plane passing through the cutting blade 4 to cause an offset correspondent for parts 6A, 7A for gripping the handles 6, 7. Generally, the grip parts 6A, 7A 6, 7 form, with the plane of the blade cutting angle δ in the range [15 - 60] degrees, preferably close to 30 degrees. As mentioned above, the handles 6, 7 carried by the carriage 5 can be separate from each other or made in contact joined. This is the case in the examples shown. So the handles 6, 7 then form a one-piece assembly affecting the shape of a pillar bridge 8 central. The top of the pillar 8 constitutes an anti-rotation support point for the thumb of the user. Parts 6A, 7A for gripping the handles which are part of a V form an angle β between them in the range [100 - 140] degrees, of preferably around 120 degrees.

    Comme l'illustre la figure 5, les parties 6A ou 7A de saisie des poignées 6 ou 7 forment chacune avec le plan de la table de coupe un angle α compris dans la plage [15 - 60] degrés, de préférence voisin de 30 degrés.As illustrated in FIG. 5, the parts 6A or 7A for gripping the handles 6 or 7 each form with the plane of the cutting table an angle α included in the range [15 - 60] degrees, preferably around 30 degrees.

    Il peut être prévu une poignée supplémentaire 14 dont l'axe longitudinal s'étend perpendiculairement à la lame de coupe. Cette poignée 14 peut être utilisée simultanément avec l'une des poignées 6 ou 7 pour réduire l'effort musculaire à fournir.An additional handle 14 can be provided, the longitudinal axis of which extends perpendicular to the cutting blade. This handle 14 can be used simultaneously with one of the handles 6 or 7 to reduce the muscular effort to provide.

    Par ailleurs et de manière en soi connue, la table de coupe est équipée de guides 12 de coupe permettant un positionnement précis du matériau en plaque à découper.Furthermore and in a manner known per se, the cutting table is equipped with cutting guides 12 allowing precise positioning of the material in cutting plate.
