Description

TOUR DE POTIER COMPORTANT UN DISPOSITIF DE GUIDAGE POUR LEPOTIER TOWER COMPRISING A GUIDANCE DEVICE FOR THE
FORMAGEFORMING
La présente invention concerne le domaine de la réalisation des poteries à l'aide de machines appelées "tour", et notamment pour la réalisation de poteries par des enfants.The present invention relates to the field of making pottery using machines called "tower", and in particular for making pottery by children.
La présente invention se rapporte plus particulièrement à un tour de potier pour le façonnage de poteries, composé d'un socle supportant une girelle pouvant être entraînée en rotation selon un axe de rotation.The present invention relates more particularly to a potter's wheel for shaping pottery, composed of a base supporting a girelle which can be rotated along an axis of rotation.
L'art antérieur connaît déjà des tours de potier pour le façonnage de poteries. II existe notamment un dispositif décrit dans la demande de brevet australien N° AU 1 503 477. Ce système permet de centrer une motte de terre par la pression d'un outil unique. Cet outil est mobile le long d'un bras. Ce bras est orientable dans toutes les directions par une poignée située dans le prolongement du bras. L'avantage de ce type de système est de faciliter le centrage de la terre, opération source de grandes difficultés pour le débutant.The prior art already knows potters' turns for the shaping of potteries. There is in particular a device described in Australian patent application No. AU 1 503 477. This system makes it possible to center a clod of earth by the pressure of a single tool. This tool is movable along an arm. This arm can be rotated in all directions by a handle located in the extension of the arm. The advantage of this type of system is to facilitate the centering of the earth, an operation which causes great difficulties for the beginner.
Ce système permet de centrer la motte de terre, mais ne permet pas d'effectuer le façonnage de la poterie à proprement parler, au cours duquel on donne une forme propre à la poterie, et au cours duquel on peut opérer une décoration en relief de la surface extérieure de la poterie . De plus, ce dispositif ne comporte qu'un seul bras de centrage. Ce dispositif est donc mal adapté au modelage d'objets de petite taille. En effet, dans ce cas, la motte de terre est de petite taille et peut se décoller facilement de la girelle. Enfin, ce dispositif ne permet pas à l'utilisateur d'être convenablement guidé lorsqu'il mime le geste que le potier effectue normalement à mains nues et ne permet donc pas de s ' initier facilement aux techniques de l'artisan potier.This system makes it possible to center the clod of earth, but does not make it possible to carry out the shaping of the pottery itself, during which one gives a form specific to the pottery, and during which one can operate a decoration in relief of the outside surface of the pottery. In addition, this device has only one centering arm. This device is therefore ill-suited to the modeling of small objects. Indeed, in this case, the clod of earth is small and can easily come off from the girelle. Finally, this device does not allow the user to be properly guided when he mimes the gesture that the potter normally performs with his bare hands and therefore does not allow him to easily learn the techniques of the artisan potter.
L'art antérieur connaît également la demande de brevet allemand N° DE 3418067 qui porte sur un tour de perçage central comportant un plateau (2) pouvant être entraîné en rotation selon un axe de rotation. Ce dispositif est muni d'un anneau de perçage (6) monté sur un axe parallèle avec l'axe de rotation du plateau (2), permettant de percer une poterie en son centre.The prior art also knows German patent application No. DE 3418067 which relates to a central drilling lathe comprising a plate (2) which can be rotated along an axis of rotation. This device is provided with a piercing ring (6) mounted on an axis parallel with the axis of rotation of the plate (2), making it possible to pierce a pottery in its center.
Ce dispositif comporte en outre des bords (4) fixes de centrage, permettant de prendre appui pour le centrage de la boule ( 3 ) .This device also comprises fixed edges (4) for centering, making it possible to rest on the centering of the ball (3).
Force est de constater que l'anneau de perçage (6) ne permet absolument pas d'aide au façonnage extérieur de la poterie puisque cet anneau est mobile verticalement selon cet axe de rotation.It is clear that the piercing ring (6) absolutely does not allow assistance in the external shaping of the pottery since this ring is movable vertically along this axis of rotation.
L'art antérieur connaît également la demande de brevet britannique N° GB 1 603 708 qui porte sur un tour pour la décoration des poteries. Ce tour est muni d'un plateau (6) pouvant être entraîné en rotation selon un axe de rotation.The prior art also knows British patent application N ° GB 1 603 708 which relates to a lathe for decorating pottery. This lathe is provided with a plate (6) which can be rotated along an axis of rotation.
Ce tour comporte en outre un bras (17) unique présentant une pointe à son extrémité et pouvant être entraîné en balayage au-dessus du plateau (6) par rotation selon un axe parallèle à l'axe de rotation du plateau (6).This turn further comprises a single arm (17) having a point at its end and which can be swept over the plate (6) by rotation along an axis parallel to the axis of rotation of the plate (6).
Ce tour ne permet pas vraiment d'exercer des efforts de façonnage à la manière du façonnage traditionnel. L'art antérieur connaît enfin le brevet américain N° US 5 047 194 qui porte sur un tour de potier pour le façonnage d'une poterie (10), du type comportant un socle (23) supportant une girelle (22) pouvant être entraînée en rotation selon un axe de rotation.This turn does not really allow to exert shaping efforts in the manner of traditional shaping. The prior art finally knows the American patent N ° US 5 047 194 which relates to a potter's wheel for the shaping of a pottery (10), of the type comprising a base (23) supporting a girelle (22) which can be driven rotating along an axis of rotation.
Ce tour est équipé d'un outil de façonnage (24), mobile dans différentes directions, présentant un tube de projection (28) présentant à son extrémité distale une buse de projection (36) par laquelle est projeté un flux d'eau (35).This lathe is equipped with a shaping tool (24), movable in different directions, presenting a projection tube (28) having at its distal end a projection nozzle (36) by which a stream of water is projected (35 ).
Le façonnage n'est donc pas opéré d'une manière traditionnelle par des efforts manuels, mais par une projection d'eau.The shaping is therefore not carried out in a traditional manner by manual efforts, but by spraying water.
La présente invention entend remédier aux inconvénients de 1 ' art antérieur en proposant un tour muni d'un dispositif de guidage qui favorise l'apprentissage des gestes manuels de façonnage, notamment pour la réalisation de poteries de petites tailles. Ce tour est particulièrement, mais non exclusivement destiné à l'apprentissage du façonnage de poteries par des enfants.The present invention intends to remedy the drawbacks of the prior art by proposing a lathe provided with a guiding device which promotes the learning of manual shaping gestures, in particular for making small-sized pottery. This tour is particularly, but not exclusively, intended for children to learn how to make pottery.
La présente invention consiste en un tour de potier pour le façonnage d'une poterie, du type comportant un socle supportant une girelle pouvant être entraînée en rotation selon un axe de rotation, caractérisé en ce qu'il comporte un dispositif de guidage comportant des moyens permettant d'opérer sur ladite poterie des efforts manuels diamétralement opposés par rapport à l'axe de rotation de ladite girelle.The present invention consists of a potter's wheel for shaping a pottery, of the type comprising a base supporting a girelle which can be rotated along an axis of rotation, characterized in that it comprises a guide device comprising means allowing to operate on said pottery manual efforts diametrically opposite with respect to the axis of rotation of said girelle.
Suivant un mode de réalisation préféré, le dispositif de guidage est constitué par au moins un plot présentant un axe sensiblement parallèle à l'axe de rotation de ladite girelle ainsi qu'au moins un bras de guidage d'un outil, ledit bras de guidage étant mobile par rapport audit plot.According to a preferred embodiment, the guide device consists of at least one stud having an axis substantially parallel to the axis of rotation of said girelle as well as at least one arm of guiding a tool, said guide arm being movable relative to said stud.
De préférence, le dispositif de guidage est constitué par un support en forme d'arche formée de deux plots reliés entre eux.Preferably, the guide device consists of an arch-shaped support formed by two studs connected to each other.
Suivant une variante avantageuse, le support est constitué d'une forme cylindrique en U renversé.According to an advantageous variant, the support consists of a cylindrical shape in an inverted U.
Avantageusement, l'outil ou les outils présente(nt) chacun une surface de travail interchangeable. De préférence, chaque outil présente une poignée.Advantageously, the tool or tools each have an interchangeable work surface. Preferably, each tool has a handle.
Suivant un mode de réalisation, ladite poignée est située sur une face opposée à la surface de travail de l'outil. Suivant un autre mode de réalisation, ladite poignée est décalée radialement par rapport à la surface de travail de l'outil.According to one embodiment, said handle is located on a face opposite to the working surface of the tool. According to another embodiment, said handle is offset radially relative to the working surface of the tool.
Suivant une variante avantageuse, le socle présente un évidemment permettant d'accueillir un réservoir d'eau amovible, afin de permettre de recueillir l'eau ayant servie au façonnage et d'évacuer plus facilement cette eau.According to an advantageous variant, the base has a recess making it possible to accommodate a removable water tank, in order to make it possible to collect the water used for shaping and to more easily evacuate this water.
On comprendra mieux l'invention à l'aide de la description, faite ci-après à titre purement explicatif, d'un mode de réalisation de l'invention, en référence aux figures annexées :The invention will be better understood using the description, given below for purely explanatory purposes, of an embodiment of the invention, with reference to the appended figures:
• La figure 1 illustre une vue en perspective d'un tour de potier selon l'invention ;• Figure 1 illustrates a perspective view of a potter's wheel according to the invention;
• La figure 2 illustre une vue de détail d'une variante préférée de réalisation du dispositif de guidage ;• Figure 2 illustrates a detailed view of a preferred embodiment of the guide device;
• La figure 3 illustre une vue de détail d'un outil à surface de travail interchangeable ; et• Figure 3 illustrates a detail view of a tool with interchangeable work surface; and
• La figure 4 illustre une vue de détail du réservoir d'eau amovible. Le tour de potier (1) selon l'invention, illustré figure 1, est du type comportant un socle (3) comportant un moteur électrique permettant d'entraîner en rotation selon un axe de rotation A une girelle (4) supportée par le socle (3).• Figure 4 illustrates a detailed view of the removable water tank. The potter's wheel (1) according to the invention, illustrated in FIG. 1, is of the type comprising a base (3) comprising an electric motor making it possible to drive in rotation about an axis of rotation A girelle (4) supported by the base (3).
De manière préférentielle, une cuvette est positionnée sous le plateau circulaire supportant la poterie en rotation, ou girelle (4), pour la récupération des liquides évacués à la périphérie de la girelle et le plateau est également percé de trous débouchant dans cette cuvette. Les liquides recueillis dans la cuvette s'écoulent ensuite dans un réservoir d'eau (16).Preferably, a bowl is positioned under the circular plate supporting the rotating pottery, or girelle (4), for the recovery of the liquids discharged at the periphery of the girelle and the plate is also pierced with holes opening into this bowl. The liquids collected in the bowl then flow into a water tank (16).
Le tour de potier (1) selon l'invention est caractérisé en ce qu'il comporte un dispositif de guidage (5) comportant des moyens permettant d'opérer sur ladite poterie (2) des efforts manuels diamétralement opposés par rapport à l'axe A de rotation de ladite girelle (4).The potter's wheel (1) according to the invention is characterized in that it comprises a guide device (5) comprising means making it possible to operate on said pottery (2) manual forces diametrically opposite with respect to the axis A of rotation of said girelle (4).
Les opérations de façonnage et de centrage de la poterie s ' effectue par un rapprochement latéral des bras de guidage. De cette façon, les outils exercent une pression sur la poterie, ce qui permet de la mettre plus facilement en forme et de la décorer par marquage de sa surface extérieure.The shaping and centering of the pottery is carried out by a lateral bringing together of the guide arms. In this way, the tools exert pressure on the pottery, which makes it easier to shape and decorate it by marking its outer surface.
Suivant un mode de réalisation de base, le dispositif de guidage est constitué par au moins un plot (6, 6') vertical présentant un axe de préférence sensiblement parallèle à l'axe A de rotation de ladite girelle (4) ainsi qu'au moins un bras (7, 7') et de préférence deux bras (7, 7') de guidage, pour le guidage respectivement d'un outil (8, 8'), ledit ou lesdits bras de guidage (7, 7') étant mobile(s) par rapport audit(s) plot(s) (6, 6'). Suivant une version préférée, le ou les bras (7, 7') de guidage est ou sont fixé(s) de manière amovible sur le ou les plot (s) (6, 6') par exemple par clipage. II est également possible de réaliser des moyens de guidage qui permettent de translater des outils selon des mouvements radiaux diamétralement opposés par rapport à l'axe A de rotation de ladite girelle (4), par exemple grâce à des systèmes de rails. Suivant un mode de réalisation, le dispositif de guidage (5) est constitué par un support (9) en forme d'arche formée de deux plots (6, 6') relié entre eux et sur lequel un ou deux bras (7, 7') sont mobiles.According to a basic embodiment, the guiding device consists of at least one vertical stud (6, 6 ') having an axis preferably substantially parallel to the axis A of rotation of said girelle (4) as well as to at least one arm (7, 7 ') and preferably two guide arms (7, 7'), for guiding a tool (8, 8 ') respectively, said guide arm (s) (7, 7') being mobile (s) with respect to said pad (s) (6, 6 '). According to a preferred version, the guide arm (s) (7, 7 ′) is or are removably fixed on the stud (s) (6, 6 ′) for example by clipping. It is also possible to produce guide means which make it possible to translate tools in radial movements diametrically opposite with respect to the axis A of rotation of said girelle (4), for example by means of rail systems. According to one embodiment, the guide device (5) consists of a support (9) in the form of an arch formed by two studs (6, 6 ') connected to each other and on which one or two arms (7, 7 ') are mobile.
De préférence, le dispositif de guidage est réalisé par deux plots disposés diamétralement opposés selon un plan passant par l'axe A de rotation de la girelle (4).Preferably, the guide device is produced by two studs arranged diametrically opposite along a plane passing through the axis A of rotation of the girelle (4).
Dans une version préférée illustrée figure 2, le dispositif de guidage (5) est constitué d'une arche d'une forme cylindrique en U renversé. Les deux plots constituant cette arche présentent chacun en coupe une forme circulaire et un axe sensiblement parallèle à l'axe A de rotation de ladite girelle. Un ou deux bras (7, 7') de guidage d'un outil (8, 8') est ou sont mobile(s) sur cette arche.In a preferred version illustrated in Figure 2, the guide device (5) consists of an arch of an inverted U-shaped cylindrical shape. The two studs constituting this arch each have in section a circular shape and an axis substantially parallel to the axis A of rotation of said girelle. One or two arms (7, 7 ') for guiding a tool (8, 8') is or are mobile (s) on this arch.
Chaque bras (7, 7') peut effectuer des mouvements de rotation autour du plot (6, 6') selon l'axe vertical du plot, permettant ainsi de travailler la forme de la poterie et de régler son diamètre. Chaque bras (7, 7') peut aussi se déplacer verticalement le long du plot (6, 6'), permettant ainsi de régler la hauteur de façonnage.Each arm (7, 7 ') can perform rotational movements around the stud (6, 6') along the vertical axis of the stud, thus making it possible to work the shape of the pottery and to adjust its diameter. Each arm (7, 7 ') can also move vertically along the stud (6, 6'), thus making it possible to adjust the shaping height.
Suivant une version avantageuse, un bras (7, 7') de guidage peut aussi être placé sur la partie supérieure courbée de l'arche reliant les deux plots (6, 6'), permettant ainsi de façonner la partie supérieure de la poterie.According to an advantageous version, a guide arm (7, 7 ′) can also be placed on the curved upper part of the arch connecting the two studs (6, 6 '), thus making it possible to shape the upper part of the pottery.
Suivant un mode de réalisation préférée, l'arche possède des encoches permettant de supporter les bras et de régler leur hauteur à des valeurs particulières.According to a preferred embodiment, the arch has notches making it possible to support the arms and to adjust their height to particular values.
Avantageusement, l'outil (8, 8') présente une surface de travail (10, 10') interchangeable, fixée de manière amovible, par exemple par clipage, à l'outil (8, 8'), comme illustré figure 3. Au cours de la fabrication, l'utilisateur va donc pouvoir utiliser différents outils selon l'action qu'il désire réaliser : centrage, façonnage ou décoration de la poterie.Advantageously, the tool (8, 8 ') has an interchangeable work surface (10, 10'), fixed in a removable manner, for example by clipping, to the tool (8, 8 '), as illustrated in FIG. 3. During manufacture, the user will therefore be able to use different tools depending on the action he wishes to perform: centering, shaping or decorating the pottery.
De plus, l'outil (8, 8') présente une poignée (12, 12'). Selon un mode de réalisation, cette poignée (12, 12') est située sur une face (11, 11') opposée à une surface de travail (10, 10'). L'utilisateur peut ainsi poser ses mains à plats derrière l'outil et se rapprocher ainsi du geste réalisé à mains nues par le potier. Selon un autre mode de réalisation de l'outil, illustré figure 1, la poignée (12, 12') est décalée radialement selon l'axe A par rapport à une surface de travail (10, 10'). Ce type de poignée permet à l'utilisateur d'appliquer une force plus importante de chaque côté de la poterie.In addition, the tool (8, 8 ') has a handle (12, 12'). According to one embodiment, this handle (12, 12 ') is located on a face (11, 11') opposite a work surface (10, 10 '). The user can thus place his hands flat behind the tool and thus get closer to the gesture made with bare hands by the potter. According to another embodiment of the tool, illustrated in FIG. 1, the handle (12, 12 ') is offset radially along the axis A with respect to a work surface (10, 10'). This type of handle allows the user to apply greater force to each side of the pottery.
Dans cet autre mode, les poignées (12, 12') sont, par exemple en forme de T.In this other mode, the handles (12, 12 ') are, for example in the shape of a T.
Le socle (3) est réalisé en matière plastique et est percé de trous destinés à permettre de ranger des outils. Il présente un évidemment (15) permettant d'accueillir un réservoir d'eau (16) amovible, illustré figure 4. L'invention est décrite dans ce qui précède à titre d'exemple.
