Les machines à couper les carreaux sont généralement constituées d'un socle pourvu d'une tablette de travail sur laquelle l'utilisateur peut faire reposer le carreau à couper. Elles sont encore constituées de deux barres de guidage montées de manière à se trouver parallèles au plan de la tablette de travail et sur lesquelles peut coulisser un chariot supportant, d'une part, un outil de coupe, généralement une pointe de carbure, prévue pour rayer le carreau à couper et, d'autre part, un pied de casse prévu pour casser le carreau sur la ligne de rayure préalablement tracée par la pointe de carbure.Tile cutting machines generally consist of a base provided with a work table on which the user can rest the tile at cut. They also consist of two guide bars mounted so as to be parallel to the plane of the work table and on which can slide a carriage supporting, on the one hand, a cutting tool, generally a carbide tip, provided to scratch the tile to be cut and, on the other hand, a breaker foot provided for break the square on the stripe line previously drawn by the carbide point.

Il peut être nécessaire de pourvoir une telle machine d'un accessoire pour effectuer d'autres découpes qu'une simple coupe. Ceci est par exemple le cas pour le perçage d'un carreau de céramique pour permettre le passage d'un tube de canalisation. It may be necessary to provide such a machine with an accessory for make other cuts than a simple cut. This is for example the case for the drilling a ceramic tile to allow the passage of a pipe.

Un tel accessoire est par exemple monté sur les barres de guidage et est pourvu d'un outil qui peut prendre deux positions : une position de repos où il est escamoté et une position de travail où il est en appui sur le carreau à percer.Such an accessory is for example mounted on the guide bars and is provided a tool which can take two positions: a rest position where it is retracted and a working position where it rests on the tile to be drilled.

De tels accessoires peuvent être vendus séparément des machines de coupe. En conséquence, ils doivent pouvoir s'adapter à différents types de machines lesquelles diffèrent par leurs dimensions, notamment le diamètre et l'entre-axe des barres de guidage. Elles peuvent également différer par la hauteur relativement à la table de travail des barres de guidage.Such accessories can be sold separately from the cutting machines. In consequently, they must be able to adapt to different types of machines which differ in their dimensions, in particular the diameter and the center distance of the bars guidance. They can also differ in height relative to the table. guide bar work.

Le but de la présente invention est de proposer un accessoire qui puisse être monté sur les barres de guidage d'une machine à couper les carreaux et qui puisse s'adapter à différents types de machines qui diffèrent par le diamètre et l'entre-axe des barres de guidage.The object of the present invention is to provide an accessory which can be mounted on the guide bars of a tile cutter and which can adapt to different types of machines which differ in the diameter and the center distance of the guide bars.

A cet effet, un accessoire selon la présente invention est caractérisé en ce qu'il comporte des moyens pour pouvoir être monté sur différents jeux de deux barres qui sont constitués, pour chaque jeu de deux barres, d'une première gorge pour pouvoir loger une première barre dudit jeu, de moyens pour solidariser ledit accessoire avec ladite première barre en butée dans le fond de ladite première gorge et d'une seconde gorge pour pouvoir loger ladite seconde barre dudit jeu de manière à ce qu'elle soit libre en translation dans ladite gorge, ladite première et ladite seconde gorges s'étendant de manière coplanaire.To this end, an accessory according to the present invention is characterized in that it includes means for being able to be mounted on different sets of two bars which consist, for each set of two bars, of a first groove to be able housing a first bar of said set, means for securing said accessory with said first bar abutting in the bottom of said first groove and a second groove to accommodate said second bar of said game so that it is free in translation in said groove, said first and said second grooves extending coplanarly.

Avantageusement, les premières et les secondes gorges s'étendent toutes de manière coplanaire, les premières gorges communiquant entre elles et les secondes gorges communiquant entre elles.Advantageously, the first and second grooves all extend from coplanar, the first gorges communicating with each other and the second gorges communicating with each other.

De plus, les premières et/ou les secondes gorges peuvent déboucher sur l'extérieur dudit accessoire dans une direction perpendiculaire au plan qui les contient. De même, les premières ou les secondes gorges débouchent sur l'extérieur dudit accessoire dans une direction parallèle au plan qui les contient.In addition, the first and / or second grooves can lead to the outside of said accessory in a direction perpendicular to the plane which contains them. Likewise, the first or second grooves open onto the outside of said accessory in a direction parallel to the plane which contains them.

Afin de pouvoir être monté sur des barres de section circulaire, ledit accessoire est avantageusement caractérisé en ce que lesdites premières et secondes gorges ont leurs fonds respectifs qui sont demi-cylindriques.In order to be able to be mounted on bars of circular section, said accessory is advantageously characterized in that said first and second grooves have their respective bottoms which are semi-cylindrical.

Par ailleurs, lesdits moyens de solidarisation peuvent être constitués de vis dont les axes passent par les axes des parties demi-cylindriques des premières gorges correspondantes. Furthermore, said securing means may consist of screws, the axes pass through the axes of the semi-cylindrical parts of the first grooves corresponding.

Afin que ledit accessoire, qui est du type qui est constitué d'un bloc destiné à être monté sur lesdites deux barres du guidage et qui porte un arbre rotatif dont l'extrémité libre est pourvue d'un outil, puisse être monté sur une machine dont les hauteurs des barres de guidage par rapport à la table travail puissent être différentes, ledit accessoire est caractérisé en ce qu'il comporte un organe de manoeuvre qui repose sur ledit bloc, des moyens pour qu'une partie dudit organe puisse sélectivement se trouver à différentes hauteurs par rapport audit bloc et une butée prévue pour coopérer avec ladite partie dudit organe de manoeuvre et pour arrêter ledit arbre en translation par rapport audit organe de manoeuvre. De plus, il comporte en outre des moyens de rappel tendant à amener ledit arbre dans la position où il est arrêté par ladite butée.So that said accessory, which is of the type which consists of a block intended for be mounted on said two guide bars and which carries a rotary shaft whose the free end is provided with a tool, can be mounted on a machine whose heights of the guide bars in relation to the work table may be different, said accessory is characterized in that it comprises an operating member which rests on said block, means so that part of said organ can selectively be find at different heights with respect to said block and a stop intended to cooperate with said part of said operating member and for stopping said shaft in translation with respect to said operating member.

    • La machine à couper les carreaux qui est représentée à la Fig. 1 est essentiellement constituée d'un socle 1 pourvu d'une tablette de travail 2 sur laquelle l'utilisateur peut faire reposer le carreau à couper. Elle est encore constituée de deux barres de guidage 3 et 4 montées, par l'intermédiaire de pieds 5 et 6, de manière à se trouver parallèles au plan de la tablette de travail 2 et sur lesquelles peut coulisser un chariot (non représenté) supportant l'outil de coupe, généralement une pointe de carbure, prévu pour rayer le carreau à couper et un pied de casse prévu pour casser le carreau sur la ligne de rayure préalablement tracée par la pointe de carbure.The tile cutter shown in Fig. 1 is essentially consisting of a base 1 provided with a work table 2 on which the user can rest the tile to be cut. It still consists of two guide bars 3 and 4 mounted, via feet 5 and 6, so as to be find parallel to the plane of the work table 2 and on which can slide a carriage (not shown) supporting the cutting tool, generally a point of carbide, intended to scratch the tile to be cut and a breaker foot provided to break the square on the stripe line previously drawn by the carbide point.

    L'accessoire 10 de la présente invention est prévu pour être monté sur les deux barres de guidage 3 et 4 et pour y être fixé. Dans l'exemple de réalisation représenté où il s'agit d'un trépan, l'accessoire 10 est pourvu d'un outil de coupe circulaire 11 (non visible à la Fig. 1 mais visible sur les autres Figs) qui est mû en rotation au moyen d'une manivelle 12. Un organe de manoeuvre 13 est prévu pour abaisser l'outil 11 de manière à ce que ce dernier vienne tangenter avec une pression sur la surface du carreau à percer. Ainsi, il est possible de percer dans un carreau de céramique un trou, par exemple pour le passage de tuyau de PVC ou autres.The accessory 10 of the present invention is intended to be mounted on both guide bars 3 and 4 and to be fixed there. In the embodiment shown where it is a drill bit, the accessory 10 is provided with a circular cutting tool 11 (not visible in Fig. 1 but visible in the other Figs) which is rotated at by means of a crank 12. An operating member 13 is provided for lowering the tool 11 so that the latter comes to tangent with a pressure on the surface of the tile to drill. Thus, it is possible to drill a hole in a ceramic tile, for example for the passage of PVC pipe or others.

    Comme on comprendra dans la suite de la description, la présente invention peut être appliquée à un accessoire 10 destiné à un autre usage que celui que l'on vient de mentionner et qui ne l'a été qu'à titre explicatif.As will be understood in the following description, the present invention can be applied to an accessory 10 intended for another use than that which we have just to mention and which was only for explanatory purposes.

    On a représenté à la Fig. 2, un accessoire 10 selon la présente invention. On voit notamment sur cette Fig. 2, l'outil de coupe circulaire 11 qui est entraíné, par l'intermédiaire d'un arbre 14, par une manivelle 12, ou comme cela est figuré dans le médaillon de la Fig. 2, par un bout d'arbre 14a sur lequel peut être monté un moteur, par exemple d'une perceuse électrique.There is shown in FIG. 2, an accessory 10 according to the present invention. We see especially in this Fig. 2, the circular cutting tool 11 which is driven, by through a shaft 14, by a crank 12, or as shown in the medallion of FIG. 2, by a shaft end 14a on which a motor can be mounted, for example an electric drill.

    L'accessoire 10 est constitué d'un bloc 15 qui est pourvu, sur un de ses flancs, d'une première gorge 15a à fond demi-cylindrique d'une première largeur L prolongée, au delà de son fond, par une seconde gorge 15b à fond également demi-cylindrique d'une seconde largeur l inférieure à ladite première largeur.The accessory 10 consists of a block 15 which is provided, on one of its sides, with a first groove 15a with a semi-cylindrical bottom of a first width L extended, beyond its bottom, by a second groove 15b also semi-cylindrical bottom of a second width l less than said first width.

    Dans le même plan que les gorges 15a et 15b mais sur l'autre flanc du bloc 15, le bloc 15 est percé d'une gorge 15c débouchant par la partie inférieure du bloc 15 et, prolongé latéralement, d'une part, en direction des gorges 15a et 15b, par une gorge 15d à fond demi-cylindrique de largeur égale à ladite première largeur L et, d'autre part, en direction opposée aux gorges 15a et 15b, par une gorge 15e à fond demi-cylindrique de largeur égale à ladite seconde largeur l. In the same plane as the grooves 15a and 15b but on the other flank of the block 15, the block 15 is pierced with a groove 15c opening out through the lower part of the block 15 and, extended laterally, on the one hand, in the direction grooves 15a and 15b, by a groove 15d with a semi-cylindrical bottom of width equal to said first width L and, on the other hand, in the opposite direction to the grooves 15a and 15b, by a groove 15e with semi-cylindrical bottom of width equal to said second width l .

    Le bloc 15 comporte des bossages 15f traversés par des vis de fixation 16 et 17. L'axe de la vis 16 passe par l'axe de la partie demi-cylindrique de la gorge 15b qui se trouve tournée vers l'intérieur du bloc 15. De même, l'axe de la vis 17 passe par l'axe de la partie demi-cylindrique de la gorge 15d qui se trouve tournée vers l'intérieur du bloc 15.The block 15 includes bosses 15f crossed by fixing screws 16 and 17. The axis of the screw 16 passes through the axis of the semi-cylindrical part of the groove 15b which is turned towards the inside of the block 15. Similarly, the axis of the screw 17 passes through the axis of the semi-cylindrical part of the groove 15d which is turned towards the inside of the block 15.

    Le bloc 15 de la Fig. 2 est monté sur deux barres 3 et 4 de diamètre égal à la largeur l des gorges 15b et 15e. Elles sont logées dans ces gorges 15b et 15e. La vis 16 est serrée sur la barre 3 et la plaque dans le fond de la gorge 15b. Le bloc 15 est ainsi solidaire de la barre 3. Par contre, la barre 4 est libre en translation dans la gorge 15e si bien que le bloc 15 peut accepter différents entre-axes de barres.Block 15 of FIG. 2 is mounted on two bars 3 and 4 of diameter equal to the width l of the grooves 15b and 15e. They are housed in these grooves 15b and 15e. The screw 16 is tightened on the bar 3 and the plate in the bottom of the groove 15b. The block 15 is thus secured to the bar 3. On the other hand, the bar 4 is free in translation in the groove 15e so that the block 15 can accept different inter-axes of bars.

    On notera que le bloc 15 est d'abord monté avec la barre 3 dans la gorge 15b, puis est pivoté de manière à faire pénétrer la barre 4 dans la gorge 15c qui est alors amenée dans la gorge 15e.It will be noted that the block 15 is first mounted with the bar 3 in the groove 15b, then is pivoted so as to penetrate the bar 4 into the groove 15c which is then brought into the throat 15th.

    Le bloc 15 de la Fig. 3 est montée sur deux barres 3 et 4 de diamètre égal à la largeur L des gorges 15a et 15b. Ces barres 3 et 4 sont respectivement logées dans les gorges 15a et 15d. La vis 17 est serrée sur la barre 4 et la plaque dans le fond de la gorge 15d. Le bloc 15 est ainsi solidaire de la barre 4. Par contre, la barre 3 est libre dans la gorge 15a si bien que le bloc 15 peut accepter différents entre-axes de barres.Block 15 of FIG. 3 is mounted on two bars 3 and 4 of diameter equal to the width L of the grooves 15a and 15b. These bars 3 and 4 are respectively housed in the gorges 15a and 15d. The screw 17 is tightened on the bar 4 and the plate in the bottom of the throat 15d. The block 15 is thus secured to the bar 4. On the other hand, the bar 3 is free in the groove 15a so that the block 15 can accept different center lines of bars.

    Comme précédemment, le bloc 15 est d'abord monté avec la barre 3 dans la gorge 15a, puis est pivoté de manière à faire pénétrer la barre 4 dans la gorge 15c qui est alors amenée dans la gorge 15d.As before, the block 15 is first mounted with the bar 3 in the groove 15a, then is pivoted so as to make the bar 4 penetrate into groove 15c which is then brought into the groove 15d.

    On constate que relativement à un jeu de barres de guidage 3,4 d'un diamètre donné, les gorges 15b et 15d ont même fonction qui est de loger dans leurs fonds une première barre dudit jeu de manière qu'elles puissent s'y trouver solidarisées, notamment avec les vis 16 et 17. Quant aux gorges 15a et 15e, elles ont également même fonction qui est d'assurer un guidage d'une seconde barre dudit jeu afin de pouvoir accepter différents entre-axes.It can be seen that, relative to a set of guide bars 3.4 with a diameter given, the grooves 15b and 15d have the same function which is to accommodate in their funds a first bar of said game so that they can be joined there, in particular with the screws 16 and 17. As for the grooves 15a and 15e, they also same function which is to provide guidance for a second bar of said set in order to be able to accept different inter-axes.

    Le bloc 15 est pourvu d'un bossage 18 percé d'un alésage 18a pour le passage de l'arbre 14 lequel porte, à son extrémité libre inférieure (sur les Figs. 2 à 5), l'outil de coupe circulaire 11. Un ressort de compression 19 est monté entre un épaulement 1 la de l'outil 11 à une extrémité et le fond d'un trou borgne 15h à l'autre extrémité.The block 15 is provided with a boss 18 pierced with a bore 18a for the passage of the shaft 14 which carries, at its lower free end (in Figs. 2 to 5), the circular section 11. A compression spring 19 is mounted between a shoulder 1 la of the tool 11 at one end and the bottom of a blind hole 15h at the other end.

    Le bossage 18 a sa surface supérieure 18b qui présente une pente descendante puis remontante sur environ 90° avec des creux 181, 182 et 183 dont les fonds se trouvent à trois hauteurs différentes par rapport au bloc 15, par exemple la base du bossage 18. La surface 18b constitue une came.The boss 18 has its upper surface 18b which has a downward and then upward slope over approximately 90 ° with recesses 18 1 , 18 2 and 18 3 whose bottoms are at three different heights relative to the block 15, for example the base of the boss 18. The surface 18b constitutes a cam.

    L'organe de manoeuvre 13 est pourvu de moyens qui sont prévus pour coopérer avec la surface supérieure 18b et ses creux 181, 182 et 183 dudit bossage 18. Ces moyens sont, dans l'exemple représenté aux Fig. 2 à 5, constitués d'un pion radial 13a.The operating member 13 is provided with means which are provided to cooperate with the upper surface 18b and its recesses 18 1 , 18 2 and 18 3 of said boss 18. These means are, in the example shown in FIGS. 2 to 5, consisting of a radial pin 13a.

    L'arbre 14 est pourvu, au niveau de la surface supérieure 13b de l'organe de manoeuvre 13 d'une butée qui est constituée d'un arrêtoir 20, par exemple une goupille ou un circlips traversant l'arbre 14, et d'une rondelle qui prend appui sur la surface 13b. Cette butée a pour fonction d'arrêter l'arbre 14 en translation par rapport audit organe de manoeuvre 13.The shaft 14 is provided, at the upper surface 13b of the operation 13 of a stop which consists of a stop 20, for example a pin or a circlip crossing the shaft 14, and a washer which bears on the surface 13b. The purpose of this stop is to stop the shaft 14 in translation with respect to said operating device 13.

    A la Fig. 2, le pion 13a de l'organe de manoeuvre 13 se trouve logé dans le creux inférieur 181. La surface supérieure 13b de l'organe de manoeuvre 13 se trouve donc à une première hauteur basse par rapport au bloc 15. Du fait que l'arbre 14 est en butée, via l'arrêtoir 20 et la rondelle 21, sur cette surface supérieure 13b, l'outil 11 se trouve à une première hauteur basse h1 par rapport à la tablette de travail 2, correspondant à une première hauteur de travail, par exemple pour un premier type de machine à couper les carreaux.In Fig. 2, the pin 13a of the operating member 13 is housed in the lower recess 18 1 . The upper surface 13b of the operating member 13 is therefore at a first low height relative to the block 15. Because the shaft 14 is in abutment, via the retainer 20 and the washer 21, on this upper surface 13b, the tool 11 is at a first low height h 1 relative to the work table 2, corresponding to a first working height, for example for a first type of machine for cutting tiles.

    A la Fig. 4, le pion 13a de l'organe de manoeuvre 13 se trouve logé dans le creux intermédiaire 182. La surface supérieure 13b de l'organe de manoeuvre 13 se trouve donc à une seconde hauteur intermédiaire par rapport au bloc 15. Du fait que l'arbre 14 est en butée sur cette surface supérieure 13b, l'outil 11 se trouve à une seconde hauteur intermédiaire h2 par rapport à la tablette de travail 2, correspondant à une seconde hauteur de travail, par exemple pour un second type de machine.In Fig. 4, the pin 13a of the operating member 13 is housed in the intermediate recess 18 2 . The upper surface 13b of the operating member 13 is therefore at a second intermediate height relative to the block 15. Because the shaft 14 is in abutment on this upper surface 13b, the tool 11 is located at a second intermediate height h 2 relative to the work table 2, corresponding to a second working height, for example for a second type of machine.

    Enfin, à la Fig. 4, le pion 13a de l'organe de manoeuvre 13 se trouve logé dans le creux supérieur 182. La surface supérieure 13b de l'organe de manoeuvre 13 se trouve donc à une troisième hauteur par rapport au bloc 15. L'outil 11 se trouve à une troisième hauteur h3 par rapport à la tablette de travail 2 correspondant à sa position d'escamotage, quelque soit le type de machine.Finally, in FIG. 4, the pin 13a of the operating member 13 is housed in the upper recess 18 2 . The upper surface 13b of the operating member 13 is therefore at a third height relative to the block 15. The tool 11 is at a third height h 3 relative to the work table 2 corresponding to its position retraction, whatever the type of machine.

    On comprendra également que l'organe de manoeuvre permet une sélection de l'une ou l'autre position selon le type de machine utilisée.It will also be understood that the operating member allows a selection of either position depending on the type of machine used.

    On comprendra que le nombre de positions de travail n'est pas limité à deux mais pourrait être supérieur dépendant du nombre de types de machine auxquels on destine l'accessoire.It will be understood that the number of working positions is not limited to two but could be higher depending on the number of types of machine intended for the accessory.
