- plaster, cement or ceramic tiles are used as building or finishing elements, fiber cement cladding boards, medium density cellulose fiber boards as cladding boards or finishing and laminated sheets as elements of a floating floor. Due to the nature of the mixture of components from which the plates are made or because of the use for which the plates are made, they have two characteristics in common: the hardness of the plate, or at least its face of use, and its thickness.
- Such a tool is for example described in the documents WO2006095065 and EP2083972 . It is a cutting tool for cutting a plate made of a reconstituted material, the tool comprising a support on which a blade is pivotally mounted by a pivot, between an open position to receive, between the support and the blade , the plate to be cut, and a closed position at the end of a cut.
- the blade has a flat, curved edge and is provided with a handle.
- the hardness of the plates to cut is generally important, a lever arm is generally provided between the handle and the blade to allow to apply a greater force.
- the carrier includes a slot for receiving at least a portion of the blade during cutting.
- the blade performs, in cooperation with the edges of the slot, a double shear: the flat sharp edge of the blade slides along the longitudinal edges of the blade, like two scissors.
- This double shear has the effect that the blade does not penetrate, during cutting, in the usual manner in the cutting plate to split it, but removes a strip of the material of the plate, band whose width corresponds substantially to that of the blade.
- the tool described in the aforementioned documents comprises a support having a large contact surface with the plate to be cut.
- This surface having the slot for receiving the blade, it is necessary to provide a relatively wide support.
- This support is then generally made of an inverted U-shaped sheet (folded or welded), to present two wings and a core.
- the slot is cut into the soul of the inverted U.
- the width of the core must be large enough so that the plate does not tilt during cutting.
- This price is also increased by the use of cutting accessories, such as a support consisting of a trestle to be arranged or the plate before cutting, and / or an angularly adjustable stop to allow transverse cuts of the plates according to selected angles.
- cutting accessories such as a support consisting of a trestle to be arranged or the plate before cutting, and / or an angularly adjustable stop to allow transverse cuts of the plates according to selected angles.
- the documents WO2006095065 and EP2083972 propose to provide on the support a fixed stop at the end of the slot opposite to the pivot axis of the blade.
- This stop has a straight edge intended to be in contact with the cutting plate.
- the stop is either provided with cooperation means with angular cutting accessories, or pivotally mounted.
- the stop can slide in the slot to reduce the distance between the stop and the pivot of the blade. Once the distance is set, the stop is screwed into position.
- the objective of the present invention is to provide a plate cutting tool in a reconstituted material economic, efficient, easily transportable, limiting the cutting dust that can hinder a quality and versatile installation.
- the cut must be precise, at least on one of the faces (the cut according to the thickness of the plate may be less accurate when this thickness is not visible on the final assembly).
- the cut must be sharp on at least one of the faces, and the cutting angle must be constant.
- the tool must allow the cutting of rectangular plates both in the transverse direction (depending on the width of the plate), but also in the longitudinal direction (depending on the length of the plate).
- a cut in the transverse direction will be called a section (this section may be parallel to the width of the plate or angular with respect to the width of the plate).
- a cut in the longitudinal direction will be called a delineation.
- the invention provides an economic stop, allowing the cutting and edging of plates, while allowing to design a tool of reduced dimensions compared to the usual practice.
- this stop although removable between the cutting position and the edging position, remains constantly on the tool, so there is no risk of losing it during edging.
- the figure 1 illustrates a cutting tool 100 of a plate made of reconstituted material, the tool comprising a support 10 and a blade 20 pivotally mounted on the support by a pivot 21, between an open position to receive, between the support 10 and the blade 20, the plate to be cut, and a closed position at the end of a cut,
- the support 10 comprises a leg portion 1 and a support portion 2 on which the blade 20 is fixed.
- the support portion 2 has a slot 3 intended to receive at least a portion of the blade 20 during cutting.
- the slot 3 is visible on the figures 3 , 8 and 11 . It comprises a proximal end 3a close to the pivot 21 and a distal end 3b, remote from the pivot,
- the portion of the support 2 comprising the slot 3 may be constituted by an inverted U-folded sheet in the core of which the slot has been cut.
- the portion of the support 2 comprising the slot 3 may also be constituted by two sheets folded in inverted L, parallel to each other.
- the slot is bordered by a wide flange (greater than the thickness of the sheets used) to allow transverse support (that is to say, perpendicular to the cutting direction, it is that is, with respect to the slot 3) of the cutting plate during cutting.
- the portion of the support 2 comprising the slot 3 is constituted by two flat sheets, parallel to each other.
- the slot 3 is bordered by a narrow rim formed by the wafer (the thickness) of each sheet 3c-3d.
- the tool comprises a notch 13 opening into the slot 3 in the vicinity of the distal end 3b.
- This notch 13 is intended to receive a stop 200 according to the invention, as illustrated, in particular, in the figure 2 .
- the abutment according to the invention makes it possible not only to wedge the plate in the cross-sectional position but also to support the plate during a cross-section or deliming.
- the stop 200 comprises a central wall 201 intended to be inserted into force in the notch 13, in the direction of the arrow F1 (see figure 3 ).
- This central wall 201 is provided, on a first plane face 202, called “contact”, with a lip 203, called “support”, extending in a first plane P1 perpendicular to the contact face 202 and positioned flush with the slot 3 in the cut position (see figure 8 ).
- a lip 205 On a second plane face 204 of the central wall 201, opposite to the contact face 202, is arranged a lip 205, called "edging", extending perpendicularly to the second plane face 204 in a second plane P2 parallel and offset relative to the first plane P1 of the support lip 203.
- the offset between the two planes P1 and P2 is chosen so that the deliming lip 205 is flush with the slot 3 in the edger utilization position (see figure 11 ).
- the support lip 203 supports the plate transversely to the cutting direction, whether the operation is a cross-section of the plate or a delineation of the plate. This avoids, when this plate is long, it breaks or tears during cutting.
- the abutment 200 further comprises a lip 206, called a "holding" lip, arranged perpendicularly to the contact face 202 in a third parallel plane P3 and offset by a determined distance d relative to the first plane of the support lip 203.
- the retaining lip 206 prevents the plate from bending V upwards when the blade crosses the plate transversely.
- the distance between the holding lip and the support lip can be chosen so that, in the use position, a space just below, equal to or greater than the thickness of the plate to be cut is formed between the support lip (flush at the slot) and the retaining lip. If the distance d is just smaller than the thickness of the plate to be cut, the latter must be inserted in force between the retaining lip 206 and the support lip 203, which prevents the user from holding the plate during the cutting.
- the figure 3 illustrates a stop 200 according to the invention being mounted on a tool according to the invention partially illustrated.
- the support lip 203 and the edging lip 205 each comprise a recess, respectively 203a and 205a, just smaller width, equal to or greater than the width Ls of the portion 2 of the support bearing the slot 3.
- the width of the indentations is of width just smaller than the width of the portion 2 of the carrier carrying the slot 3.
- the retaining lip 206 has a notch 206a to allow the insertion of the stop into the notch 13 in the edging position (see Figures 11 to 13 ).
- the notch 206a has a width just smaller than the width Ls of the support portion carrying the slot.
- the holding lip is inserted in force on either side of said portion 2.
- the stopper can be inserted into the notch 13, the notches 203a and 205a must be aligned perpendicular to the position of use.
- the notch 206a must be aligned with the notches 203a and 205a of the support lips 203 and deliming 205.
- the abutment further comprises, on the second plane face 204, a shim 210a, 210b, 210c.
- This wedge is perpendicular to the second plane face 204 and perpendicular to the edging lip 205.
- the shim is intended to be inserted into the slot 3 of the portion of the support in the use position.
- this wedge has a thickness just greater than the width of the slot 3 so that it must be inserted forcefully in the slot.
- the wedge 210a, 210b, 210c thus contributes to maintaining the stop in the position of use and prevents the stop from pivoting in the notch 13.
- the shim 210a, 210b, 210c stiffens the abutment 200 according to the invention.
- the tool comprises a support 10 on which a blade 20 is pivotally mounted by a pivot 21.
- the support comprises a leg portion 1 and a portion 2 provided with a slot 3 for receiving at least a portion of the blade 20 during cutting.
- the slot comprises at its distal end 3b, remote from the pivot 21, a notch 13 in which is inserted a stop according to the figure 7 .
- the stop is positioned in the cutting use position by inserting the medial wall 201 in the notch 13, so that the contact face 202 and the support lip 203 are directed towards the slot 3 .
- the deliming lip 205 is directed opposite the slot 3.
- the deliming lip 205 is located below the support lip 203 and the latter is flush with the slot 3.
- the plane P2 on which the edging lip 205 extends is located below the plane P1 on which the support lip 203 extends.
- the plane P1 on which the support lip 203 extends is located below the plane P3 on which the holding lip 206 extends.
- the figure 9 illustrates the tool in the open position and in which a plate A, illustrated in dotted lines, is brought into position along the arrow F2 between the blade 20 and the portion 2 of the support carrying the slot 3.
- the plate A is then inserted between the retaining lip 206 and the support lip 203 on which it rests transversely. The plate A is thus placed against the contact face 202 of the abutment and on the support lip 203.
- the blade 20 is pivoted about the pivot 21 to bring it in the closed position in the direction of the arrow F3.
- the blade is then in the closed position as illustrated in FIG. figure 10 .
- FIGS. 11 to 13 illustrate the use of the abutment according to the invention for the edging of a plate A.
- the abutment 200 is positioned in the edging utilization position by inserting the medial wall 201 in the notch 13 so that the contact face 202 and the support lip 203 are directed. towards the slot 3.
- the deliming lip 205 is, for its part, directed opposite the slot 3.

- the blade 20 is pivoted about the pivot 21 to bring it in the closed position, in the direction of the arrow F5, as shown in FIG. figure 12 .
- the dimensions of the tool are insufficient to allow edging of the plate A in a single operation.
- the blade 20 is repositioned in the open position in the direction of the arrow F6 ( figure 13 ) and the plate A is pushed in the direction of the arrow F7 towards the pivot 21, always resting on the deliming lip 205.
- the blade 20 is then pivoted about the pivot 21 to bring it into the closed position.
- the present invention therefore makes it possible to provide a stop capable of ensuring both the cross-sectional function and the longitudinal edging of a plate.
- the abutment according to the invention allows transverse support of the plate whether in cross section or edging. It is therefore possible to manufacture the support portion 2 comprising the slot 3 with two single unfolded metal plates, thereby having a low transverse support capacity of the plate.
- the tool according to the invention is as efficient as a tool whose portion 2 has a width Ls sufficiently large to support the plate transversely.

Description
L'invention concerne une butée à double fonction pour un outil de découpe de plaque, notamment une plaque faite en un matériau reconstitué, ainsi qu'un outil de découpe comportant une telle butée à double fonction et un procédé de coupe et de délignage d'une plaque à l'aide d'un outil muni d'une telle butée.The invention relates to a dual function stop for a plate cutting tool, in particular a plate made of a reconstituted material, as well as to a cutting tool comprising such a double-function stop and a cutting and edging method. a plate using a tool provided with such a stop.
Dans le domaine de la construction, moderne, on utilise souvent des éléments de construction formés ou reconstitués à partir de matériaux qui se présentent ou qui sont réduits en poudre, en fibres, en granulés ou en copeaux. Ainsi, à titre d'exemples non limitatifs, on utilise des carreaux de plâtre, de ciment ou de céramique comme éléments de construction ou de finition, des plaques de bardage en fibrociment, des plaques en fibres cellulosiques de densité moyenne comme plaques de revêtement ou de finition et des plaques stratifiées comme éléments d'un parquet flottant. En raison de la nature du mélange de composants à partir duquel les plaques sont faites ou en raison de l'utilisation pour laquelle les plaques sont faites, elles ont deux caractéristiques en commun : la dureté de la plaque, ou pour le moins de sa face d'utilisation, et son épaisseur.In the modern construction field, structural elements formed or reconstituted from materials which are present or which are reduced to powder, fibers, granules or chips are often used. Thus, by way of non-limiting examples, plaster, cement or ceramic tiles are used as building or finishing elements, fiber cement cladding boards, medium density cellulose fiber boards as cladding boards or finishing and laminated sheets as elements of a floating floor. Due to the nature of the mixture of components from which the plates are made or because of the use for which the plates are made, they have two characteristics in common: the hardness of the plate, or at least its face of use, and its thickness.
Lorsque les plaques sont faites en un matériau reconstitué réunissant dureté et épaisseur, il faut disposer d'un outil capable de surmonter ces deux difficultés de coupe.When the plates are made of a reconstituted material combining hardness and thickness, it is necessary to have a tool capable of overcoming these two difficulties of cutting.
Il existe de nombreux outils capables de couper de telles plaques. Néanmoins, la pose de ces plaques se faisant sur le chantier, l'outil doit être adapté à une utilisation sur le chantier, c'est-à-dire hors d'un atelier.There are many tools that can cut such plates. However, since these plates are laid on site, the tool must be suitable for use on site, that is to say outside a workshop.
Un tel outil est par exemple décrit dans les documents
Le support comprend une fente destinée à recevoir au moins une partie de la lame au cours de la coupe.The carrier includes a slot for receiving at least a portion of the blade during cutting.
La lame effectue, en coopération avec les bords de la fente, un cisaillement double : le tranchant plat et net de la lame glisse le long des bords longitudinaux de la lame, comme deux ciseaux. Ce cisaillement double a pour effet que la lame ne pénètre pas, au cours de la découpe, de manière habituelle dans la plaque à découper pour la fendre, mais enlève une bande du matériau de la plaque, bande dont la largeur correspond sensiblement à celle de la lame.The blade performs, in cooperation with the edges of the slot, a double shear: the flat sharp edge of the blade slides along the longitudinal edges of the blade, like two scissors. This double shear has the effect that the blade does not penetrate, during cutting, in the usual manner in the cutting plate to split it, but removes a strip of the material of the plate, band whose width corresponds substantially to that of the blade.
Pour garantir que les découpes des plaques soient régulières, l'outil décrit dans les documents précités comprend un support présentant une surface de contact importante avec la plaque à découper. Cette surface comportant la fente de réception de la lame, il est nécessaire de prévoir un support relativement large. Ce support est alors constitué, généralement, d'une tôle en U inversé (pliée ou soudée), afin de présenter deux ailes et une âme. La fente est découpée dans l'âme du U inversé. La largeur de l'âme doit être suffisamment importante pour que la plaque ne bascule pas lors de la découpe.To ensure that the blanks of the plates are regular, the tool described in the aforementioned documents comprises a support having a large contact surface with the plate to be cut. This surface having the slot for receiving the blade, it is necessary to provide a relatively wide support. This support is then generally made of an inverted U-shaped sheet (folded or welded), to present two wings and a core. The slot is cut into the soul of the inverted U. The width of the core must be large enough so that the plate does not tilt during cutting.
Ceci nécessite généralement d'utiliser plus de matière première, ce qui augment le poids de l'outil et, bien entendu son prix.This generally requires the use of more raw material, which increases the weight of the tool and, of course, its price.
Ce prix est aussi augmenté par l'utilisation d'accessoires de coupe, tel qu'un support constitué par un tréteau à disposer soit la plaque avant la découpe, et/ou qu'une butée réglable angulairement pour permettre des découpes transversales des plaques selon des angles choisis.This price is also increased by the use of cutting accessories, such as a support consisting of a trestle to be arranged or the plate before cutting, and / or an angularly adjustable stop to allow transverse cuts of the plates according to selected angles.
Ainsi, les documents
Si ces outils permettent le réglage de l'angle de coupe, la butée est perfectionnée et munie de nombreuses options coûteuses en poids et en matière première.If these tools allow the adjustment of the cutting angle, the stop is improved and provided with many expensive options in weight and raw material.
L'objectif de la présente invention est de proposer un outil de découpe de plaques en un matériau reconstitué économique, performant, facilement transportable, limitant la poussière de coupe qui peut gêner une pose de qualité, et polyvalent.The objective of the present invention is to provide a plate cutting tool in a reconstituted material economic, efficient, easily transportable, limiting the cutting dust that can hinder a quality and versatile installation.
Par performant, on entend que la coupe doit être précise, au moins sur l'une des faces (la coupe selon l'épaisseur de la plaque peut être moins précise lorsque cette épaisseur ne se voit pas sur le montage final). Ainsi la coupe doit être nette sur au moins l'une des faces, et l'angle de coupe doit être constant.By performing, it is meant that the cut must be precise, at least on one of the faces (the cut according to the thickness of the plate may be less accurate when this thickness is not visible on the final assembly). Thus the cut must be sharp on at least one of the faces, and the cutting angle must be constant.
Par polyvalent, on entend que l'outil doit permettre la découpe de plaques rectangulaires à la fois dans le sens transversal (selon la largeur de la plaque), mais également dans le sens longitudinal (selon la longueur de la plaque).By polyvalent means that the tool must allow the cutting of rectangular plates both in the transverse direction (depending on the width of the plate), but also in the longitudinal direction (depending on the length of the plate).
Dans la suite de la présente description, une découpe dans le sens transversal sera appelée une coupe (cette coupe peut être parallèle à la largeur de la plaque ou anguleuse par rapport à la largeur de la plaque). Une découpe dans le sens longitudinal sera appelée un délignage.In the remainder of the present description, a cut in the transverse direction will be called a section (this section may be parallel to the width of the plate or angular with respect to the width of the plate). A cut in the longitudinal direction will be called a delineation.
Or, pour permettre le délignage de plaque relativement longues, il a toujours été considéré que l'outil devait lui-même avoir des dimensions importantes pour permettre le soutien de la plaque pendant le délignage.However, to allow relatively long plate delimbing, it has always been considered that the tool itself had to have significant dimensions to allow the support of the plate during edging.
Ceci nécessite donc l'utilisation de plus de matière première, ce qui augment le poids et le prix de ces outils.This requires the use of more raw material, which increases the weight and price of these tools.
L'invention propose une butée économique, permettant les coupes et le délignage de plaques, tout en permettant de concevoir un outil de dimensions réduites par rapport à la pratique habituelle. En outre, cette butée, bien qu'amovible entre la position de coupe et la position de délignage, reste constamment sur l'outil, de sorte qu'il n'y a plus de risque de la perdre pendant le délignage.The invention provides an economic stop, allowing the cutting and edging of plates, while allowing to design a tool of reduced dimensions compared to the usual practice. In addition, this stop, although removable between the cutting position and the edging position, remains constantly on the tool, so there is no risk of losing it during edging.

Le support 10 comporte une portion de piètement 1 et une portion de support 2 sur laquelle est fixée la lame 20. La portion de support 2 comporte une fente 3 destinée à recevoir au moins une partie de la lame 20 au cours de la coupe. La fente 3 est visible sur les
La portion du support 2 comprenant la fente 3 peut être constituée par une tôle pliée en U inversé dans l'âme duquel la fente a été découpée.The portion of the
La portion du support 2 comprenant la fente 3 peut également être constituée par deux tôles pliées en L inversé, parallèles entre elles.The portion of the
Dans ces deux modes de réalisation, la fente est bordée par un rebord large (supérieur à l'épaisseur des tôles utilisée) pour permettre un soutien transversale (c'est-à-dire perpendiculairement par rapport à la direction de découpe, c'est-à-dire par rapport à la fente 3) de la plaque à découper pendant la découpe.In these two embodiments, the slot is bordered by a wide flange (greater than the thickness of the sheets used) to allow transverse support (that is to say, perpendicular to the cutting direction, it is that is, with respect to the slot 3) of the cutting plate during cutting.
Avantageusement, pour limiter la quantité de matière utilisée, la portion du support 2 comprenant la fente 3 est constituée par deux tôles planes, parallèles entre elles.Advantageously, to limit the amount of material used, the portion of the
Dans ce mode de réalisation, illustré partiellement à la
Selon l'invention, l'outil comprend une encoche 13 débouchant dans la fente 3 au voisinage de l'extrémité distale 3b.According to the invention, the tool comprises a
Cette encoche 13 est destinée à recevoir une butée 200 selon l'invention, telle qu'illustrée, notamment, à la
La butée selon l'invention permet non seulement de caler la plaque en position de coupe transversale mais également de supporter la plaque pendant une coupe transversale ou un délignage.The abutment according to the invention makes it possible not only to wedge the plate in the cross-sectional position but also to support the plate during a cross-section or deliming.
Ainsi, la butée 200 selon l'invention, et illustrée en
Cette paroi médiane 201 est munie, sur une première face plane 202, dite « de contact », d'une lèvre 203, dite « de soutien », s'étendant dans un premier plan P1 perpendiculaire à la face de contact 202 et positionnée de manière à affleurer au niveau de la fente 3 en position d'utilisation de coupe (voir
Sur une seconde face plane 204 de la paroi médiane 201, opposée à la face de contact 202, est agencée une lèvre 205, dite « de délignage », s'étendant perpendiculairement à la seconde face plane 204 selon un deuxième plan P2 parallèle et décalé par rapport au premier plan P1 de la lèvre de soutien 203. Le décalage entre les deux plans P1 et P2 est choisi pour que la lèvre de délignage 205 affleure au niveau de la fente 3 en position d'utilisation de délignage (voir
La lèvre de soutien 203 supporte la plaque transversalement par rapport à la direction de découpe, que l'opération soit une coupe transversale de la plaque ou un délignage de la plaque. Ceci évite, lorsque cette plaque est longue, qu'elle ne se casse ou se déchire pendant la découpe.The
Ceci est particulièrement avantageux car il est possible de réaliser un support très économique, tout en assurant un soutien de la plaque à découper pendant la coupe.This is particularly advantageous because it is possible to achieve a very economical support, while providing support for the cutting plate during cutting.
Avantageusement, la butée 200 selon l'invention comprend, en outre, une lèvre 206, dite « de maintien », agencée perpendiculairement à la face de contact 202 selon un troisième plan P3 parallèle et décalé d'une distance déterminée d par rapport au premier plan de la lèvre de soutien 203.Advantageously, the
La lèvre de maintien 206 évite que la plaque ne se plie en V vers le haut lorsque la lame coupe transversalement la plaque.The retaining
La distance entre la lèvre de maintien et la lèvre de soutien peut être choisie pour que, en position d'utilisation, un espace juste inférieur, égal ou supérieur à l'épaisseur de la plaque à découper soit ménagé entre la lèvre de soutien (affleurant au niveau de la fente) et la lèvre de maintien. Si la distance d est juste inférieure à l'épaisseur de la plaque à découper, cette dernière devra être insérée en force entre la lèvre de maintien 206 et la lèvre de soutien 203, ce qui évite à l'utilisateur de tenir la plaque pendant la découpe.The distance between the holding lip and the support lip can be chosen so that, in the use position, a space just below, equal to or greater than the thickness of the plate to be cut is formed between the support lip (flush at the slot) and the retaining lip. If the distance d is just smaller than the thickness of the plate to be cut, the latter must be inserted in force between the retaining
La
Dans cette vue en perspective, la lèvre de soutien 203 et la lèvre de délignage 205 comportent chacune une échancrure, respectivement 203a et 205a, de largeur juste inférieure, égale ou supérieure à la largeur Ls de la portion 2 du support portant la fente 3.In this perspective view, the
Ces échancrures 203a et 205a permettent d'insérer la paroi médiane 201 de la butée dans l'encoche 13.These
De préférence, la largeur des échancrures est de largeur juste inférieure à la largeur de la portion 2 du support portant la fente 3. Ainsi, il y a un frottement supplémentaire entre la portion 2 du support et les lèvres de soutien 203 et de délignage 205, de telle sorte que les lèvres de soutien 203 et de délignage 205 doivent être insérées en force de part et d'autre de la portion 2 du support. Ceci contribue à maintenir la butée dans l'encoche 13 et à éviter que la butée ne pivote dans l'encoche.Preferably, the width of the indentations is of width just smaller than the width of the
De la même manière, la lèvre de maintien 206 comporte une échancrure 206a pour permettre l'insertion de la butée dans l'encoche 13 en position de délignage (voir
Avantageusement, comme pour les échancrures 203a et 205a, l'échancrure 206a présente une largeur juste inférieure à la largeur Ls de la portion de support portant la fente.Advantageously, as for the
Ainsi, lors du positionnement de la butée, la lèvre de maintien est insérée en force de part et d'autre de ladite portion 2.Thus, during the positioning of the stop, the holding lip is inserted in force on either side of said
Bien entendu, pour que la butée puisse être insérée dans l'encoche 13, les échancrures 203a et 205a doivent être alignées perpendiculairement par rapport à la position d'utilisation.Of course, for the stopper can be inserted into the
De la même manière, lorsque la butée comporte une lèvre de maintien 206, l'échancrure 206a doit être alignée avec les échancrures 203a et 205a des lèvres de soutien 203 et de délignage 205.In the same way, when the stop has a retaining

Sur ces figures, la butée comporte, en outre, sur la seconde face plane 204, une cale 210a, 210b, 210c.In these figures, the abutment further comprises, on the
Cette cale est perpendiculaire à la seconde face plane 204 et perpendiculaire à la lèvre de délignage 205.This wedge is perpendicular to the
La cale est destinée à être insérée dans la fente 3 de la portion du support en position d'utilisation.The shim is intended to be inserted into the
Avantageusement, cette cale présente une épaisseur juste supérieure à la largeur de la fente 3 de telle sorte qu'elle doit être insérée en force dans la fente.Advantageously, this wedge has a thickness just greater than the width of the
La cale 210a, 210b, 210c contribue ainsi au maintien de la butée dans la position d'utilisation et évite à la butée de pivoter dans l'encoche 13.The
En outre, la cale 210a, 210b, 210c rigidifie la butée 200 selon l'invention.In addition, the
La forme de la cale 210a, 210b, 210c est arbitraire mais doit être adaptée au support 10 en ce sens qu'elle ne doit pas empêcher l'insertion de la butée dans l'encoche 13 du support 2.

L'outil comporte un support 10 sur lequel une lame 20 est montée pivotante par un pivot 21.The tool comprises a
Le support comprend une portion de piètement 1 et une portion 2 munie d'une fente 3 destinée à recevoir au moins une partie de la lame 20 au cours de la coupe.The support comprises a leg portion 1 and a
La fente comprend à son extrémité distale 3b, éloignée du pivot 21, une encoche 13 dans laquelle est insérée une butée conforme à la
Dans ce mode de réalisation, la butée est positionnée en position d'utilisation de coupe en insérant la paroi médiane 201 dans l'encoche 13, de telle sorte que la face de contact 202 et la lèvre de soutien 203 soient dirigées vers la fente 3.In this embodiment, the stop is positioned in the cutting use position by inserting the

La plaque A est alors insérée entre la lèvre de maintien 206 et la lèvre de soutien 203 sur laquelle elle repose transversalement. La plaque A est ainsi placée contre la face de contact 202 de la butée et sur la lèvre de soutien 203.The plate A is then inserted between the retaining
Puis la lame 20 est pivotée autour du pivot 21 pour l'amener en position fermée dans le sens de la flèche F3.Then the
La lame est alors en position fermée comme illustré à la
Dans cette position, la plaque A a été coupée dans le sens transversal.In this position, the plate A has been cut in the transverse direction.

Dans ce mode de réalisation, la butée 200 selon l'invention est positionnée en position d'utilisation de délignage en insérant la paroi médiane 201 dans l'encoche 13 de telle sorte que la face de contact 202 et la lèvre de soutien 203 soient dirigées vers la fente 3.In this embodiment, the
La lèvre de délignage 205 est, quant à elle, dirigée à l'opposé de la fente 3.The
La lèvre de délignage 205 est située au dessus de la lèvre de soutien 203 et affleure au niveau de la fente 3.The edging
Autrement dit, le plan P2 selon lequel s'étend la lèvre de délignage se situe au dessus du plan P1 selon lequel s'étend la lèvre de soutien 203. Le plan P2 est dans le prolongement de la fente 3.In other words, the plane P2 along which the edging lip extends is above the plane P1 along which the
Ce mode de réalisation de la butée comprenant une lèvre de maintien 206, le plan P3 selon lequel s'étend la lèvre de maintien 206 s'étend en dessous du plan P1 selon lequel s'étend la lèvre de soutien 203.This embodiment of the abutment comprising a retaining
La lèvre de délignage 205 affleurant au niveau de la fente 3, la plaque A est positionnée sur la portion 2 du support comprenant la fente 3 dans le sens de la flèche F4, en appui sur la lèvre de délignage 205 qui supporte la plaque A transversalement.The
Puis la lame 20 est pivotée autour du pivot 21 pour l'amener en position fermée, dans le sens de la flèche F5, comme illustré à la
Généralement, les dimensions de l'outil sont insuffisantes pour permettre un délignage de la plaque A en une seule opération.Generally, the dimensions of the tool are insufficient to allow edging of the plate A in a single operation.
Dans ce cas, la lame 20 est repositionnée en position ouverte dans le sens de la flèche F6 (
La lame 20 est alors pivotée autour du pivot 21 pour l'amener en position fermée.The
Ces opérations sont répétées jusqu'à ce que la plaque soit complètement délignée.These operations are repeated until the plate is completely sliced.
La présente invention permet donc de proposer une butée capable d'assurer à la fois la fonction de coupe transversale et de délignage longitudinal d'une plaque.The present invention therefore makes it possible to provide a stop capable of ensuring both the cross-sectional function and the longitudinal edging of a plate.
En outre, cette butée n'est jamais laissée de côté pendant les opérations de sorte qu'il n'y a aucun risque de la perdre sur le chantier ou de l'abîmer.In addition, this stop is never left out during operations so there is no risk of losing it on the site or damage.
Par ailleurs, la butée selon l'invention permet un support transversal de la plaque que ce soit en coupe transversale ou en délignage. Il est donc possible de fabriquer la portion 2 de support comprenant la fente 3 avec deux simples plaques métalliques non pliées, présentant de ce fait une faible capacité de soutien transversal de la plaque.Furthermore, the abutment according to the invention allows transverse support of the plate whether in cross section or edging. It is therefore possible to manufacture the
Un tel support est donc beaucoup plus économique à la fois en matière première et en opération de fabrication. Néanmoins, la butée assurant le soutien transversal en coupe et en délignage, l'outil selon l'invention est aussi performant qu'un outil dont la portion 2 présente une largeur Ls suffisamment importante pour supporter transversalement la plaque.Such a support is therefore much more economical both in raw material and in manufacturing operation. Nevertheless, since the abutment provides transverse support in section and edging, the tool according to the invention is as efficient as a tool whose
