Description

Outil pour couper une feuille de matière.Tool for cutting a sheet of material.
La présente invention concerne un outil spécialement destiné à couper une feuille de matière quelconque dans un angle, par exemple pour couper une feuille de revêtement mural dans les angles d'une pièce d'habitation ou d'un local. Il peut s'agir de feuilles de matière telles que fibres de verre et revêtements à dossier vinylique mais plus particulièrement du papier peint.The present invention relates to a tool specially intended for cutting any sheet of material in a corner, for example for cutting a sheet of wall covering in the corners of a living room or room. It can be sheets of material such as glass fibers and vinyl-backed coverings, but more particularly wallpaper.
Il est connu d'utiliser un couteau de type CUTTER pour découper des feuilles de revêtement mural lors d'un tapissage ou d'une décoration. Un inconvénient de ce type de couteau est que son emploi dans un angle de deux murs nécessite de se munir d'une palette pour maintenir la feuille de revêtement dans l'angle durant la découpe car sinon le revêtement serait arraché ou du moins coupé de façon imprécise.It is known to use a CUTTER type knife to cut sheets of wall covering during an upholstery or decoration. A disadvantage of this type of knife is that its use in a corner of two walls requires having a pallet to keep the covering sheet in the corner during cutting because otherwise the covering would be torn off or at least cut so imprecise.
L'invention a notamment pour but d'éviter l'emploi de plusieurs outils simultanément pour découper des feuilles de matière souple dans un angle.The object of the invention is in particular to avoid the use of several tools simultaneously for cutting sheets of flexible material at an angle.
Cet objectif est atteint grâce à l'invention qui propose un outil de coupe qui permet de découper de manière aisée, régulière et précise une feuille de matière souple quelconque, plus particulièrement du papier peint mural, dans un angle.This objective is achieved thanks to the invention which proposes a cutting tool which makes it possible to cut easily, regularly and precisely a sheet of any flexible material, more particularly mural wallpaper, in a corner.
Selon un aspect de l'invention, la tête du corps de l'outil présente deux faces obliques situées dans deux plans qui s'étendent de part et d'autre de la fente précitée à partir de la tête, lesdites faces obliques se joignant suivant une arête qui s'étend longitudinalement au plan de la lame, la lame coupante sortant obliquement de ladite tête exactement à une extrémité de l'arête précitée et de l'alignement de celle-ci. Lesdites faces obliquent forment de préférence un angle variant de 25 à 50°.According to one aspect of the invention, the head of the tool body has two oblique faces located in two planes which extend on either side of the slot above from the head, said oblique faces joining along an edge which extends longitudinally to the plane of the blade, the cutting blade leaving obliquely from said head exactly at one end of the aforementioned edge and the alignment of that -this. Said oblique faces preferably form an angle varying from 25 to 50 °.
Avec l'outil suivant l'invention, les faces obliques précitées servent d'éléments d'appui qui obligent une feuille de matière souple à épouser correctement le profil de l'angle avant le passage de la lame coupante dans l'alignement de l'arête d'appui. La feuille de revêtement peut ainsi être découpée de manière précise et régulière sans devoir recourir à un outil supplémentaire quelconque. Bien entendu l'outil suivant l'invention peut également être utilisé contre une surface de support simple comme un couteau (cutter) classique.With the tool according to the invention, the abovementioned oblique faces serve as support elements which force a sheet of flexible material to correctly match the profile of the angle before the cutting blade passes in alignment with the support edge. The covering sheet can thus be cut precisely and evenly without having to resort to any additional tool. Of course the tool according to the invention can also be used against a simple support surface like a conventional knife (cutter).
Selon un mode de réalisation particulier de l'invention, l'arête est à cet effet tronquée pour fournir une face plate allongée parallèlement à l'arête primitive et perpendiculaire au plan de l'outil.According to a particular embodiment of the invention, the edge is for this purpose truncated to provide a flat elongated face parallel to the original edge and perpendicular to the plane of the tool.
Selon un autre aspect de l'invention, pour la découpe de papier de revêtement mural, il est particulièrement important de pouvoir sortir la lame à travers la fente de manière progressive, la lame pouvant émerger de la tête d'une longueur aussi réduite que souhaitée par exemple 1 mm ou moins. Cette possibilité n'est possible qu'en prévoyant une lame à expulsion sans cran d'arrêt. La lame est alors maintenue par effet de friction, de préférence par friction dans une glissière ou coulisse, d'un chariot-curseur auquel elle a été solidarisée de manière connue. De manière surprenante l'expérience montre que la lame peut être sortie d'une portion variable, parfaitement controllable avec un doigt actionnant le curseur-chariot, et avec un positionnement stable durant les opérations de découpe.According to another aspect of the invention, for cutting wallcovering paper, it is particularly important to be able to extend the blade through the slot gradually, the blade can emerge from the head as short as desired for example 1 mm or less. This possibility is only possible by providing an expulsion blade without stopper. The blade is then held by friction effect, preferably by friction in a slide or slide, of a slider carriage to which it has been secured in known manner. Surprisingly, experience shows that the blade can be taken out of a variable portion, perfectly controllable with a finger actuating the slider-carriage, and with stable positioning during the cutting operations.
De préférence la glissière comprendra des rainures avec nervures, p.e. latérales, aptes à enserrer ou à être enserrées par un élément longitudinal du curseur. Les dimensions des gorges, nervures et rainures seront donc prévues très précises et stables. Selon une variante préférée ledit curseur comprendra un élément élastique, p.e. un ressort à lame, apte à exercer une pression suffisante sur un élément de la rainure, p.e. sur une nervure latérale, pour maintenir par friction la lame en utilisation, tout en permettant son réglage précis par coulissement du curseur. On peut cependant prévoir un élément de blocage de la lame, plus particulièrement pour un blocage en position de sécurité, ou un arrangement de repère visuel permettant de s'assurer que la lame ne sort pas du tout de la tête de l'outil.Preferably, the slide will include grooves with ribs, e.g. lateral, capable of enclosing or being gripped by a longitudinal element of the cursor. The dimensions of the grooves, ribs and grooves will therefore be provided very precise and stable. According to a preferred variant, said slider will comprise an elastic element, eg a leaf spring, capable of exerting sufficient pressure on an element of the groove, eg on a lateral rib, to frictionally maintain the blade in use, while allowing its adjustment precise by sliding the cursor. However, it is possible to provide a blade locking element, more particularly for locking in the safety position, or an arrangement of visual cues making it possible to ensure that the blade does not come out at all from the head of the tool.
La gorge comprenant la rainure et les nervures est de préférence ouverte à l'extrémité libre du manche, permettant ainsi le retrait du curseur et éventuellement de la lame y solidarisée, hors du corps allongé plat. Avantageusement, la fente de sortie de la lame peut être prévue d'une épaisseur juste inférieure à l'épaisseur d'une lame de telle sorte que cette fente joue également le rôle de guide.The groove comprising the groove and the ribs is preferably open at the free end of the handle, thus allowing the withdrawal of the cursor and possibly of the blade therein secured, outside the elongated flat body. Advantageously, the outlet slot of the blade can be provided with a thickness just less than the thickness of a blade so that this slot also acts as a guide.
Selon un mode particulier de l'invention, le corps comprenant le manche, la tête, les rainures et nervures est entièrement en matière plastique, avantageusement d'une seule pièce, éventuellement même moulé d'une seule pièce. Seule la formation de la fente constituerait éventuellement une opération séparée. Les autres éléments de l'outil sont connus et se trouvent communément dans la commerce (lames, curseur) .According to a particular embodiment of the invention, the body comprising the handle, the head, the grooves and ribs is entirely made of plastic, advantageously in one piece, possibly even molded in one piece. Only the formation of the slot would possibly constitute a separate operation. The other elements of the tool are known and are commonly found on the market (blades, slider).
Selon un aspect de l'invention, lorsque la lame est à segments séparables comme connu en soi, on prévoit aussi un casse-lame qui a la particularité de pouvoir être inséré et glissé dans la glissière du curseur qui comme indiqué, est de préférence ouverte à une extrémité. Le casse-lame peut lui-même coulisser dans la coulisse ou glissière derrière le curseur de réglage de la lame.According to one aspect of the invention, when the blade is with separable segments as known per se, there is also provided a blade breaker which has the particularity of being able to be inserted and slid into the slide of the cursor which, as indicated, is preferably open at one end. The breaker can itself slide in the slide or slide behind the blade adjustment slider.
Selon encore un autre aspect de l'invention, le profil de l'élément plat allongé formant manche présente , à la partie supérieure, opposée à l'arête, un évidement ou une dépression antérieure, plus ou moins courbe ou progressive, susceptible de recevoir un doigt de l'utilisateur tenant en main ledit outil. Ce doigt sera généralement l'index ou le pouce. L'index sera plus précisément utilisé lorsque l'outil est maintenu à bout de bras, par exemple pour effectuer une très longue ligne de coupe. L'outil est ainsi d'une forme particulièrement ergonomique. Le profil de la tête est en continuité avec le profil du manche, l'extrémité antérieure, du côté de la fente de la lame, étant approximativement perpendiculaire à l'arête.According to yet another aspect of the invention, the profile of the elongated flat element forming a handle has, at the upper part, opposite the edge, a recess or an anterior depression, more or less curved or progressive, capable of receiving a user's finger holding said tool in hand. This finger will usually be the index or thumb. The index finger will be used more precisely when the tool is held at arm's length, for example to make a very long cutting line. The tool is thus particularly shaped ergonomic. The profile of the head is in continuity with the profile of the handle, the anterior end, on the side of the slot of the blade, being approximately perpendicular to the edge.
Un mode de réalisation de l'invention est décrit dans ce qui suit à titre d'exemple à l'aide des dessins joints.An embodiment of the invention is described in the following by way of example with the aid of the accompanying drawings.
La figure 1 est une vue de côté d'un outil suivantFigure 1 is a side view of a following tool

La figure 2 est une vue en élévation de l'outil de la figure 1.Figure 2 is an elevational view of the tool of Figure 1.
La figure 3 montre la tête de coupe de la figure l en action durant la découpe d'une feuille de revêtement mural dans l'angle formé par deux surfaces de support.FIG. 3 shows the cutting head of FIG. 1 in action during the cutting of a wall covering sheet in the angle formed by two support surfaces.
La figure 4 montre la tête de l'outil de la figure 1 en action durant la découpe d'une feuille de revêtement contre une surface de support simple. La figure 5 est une vue de l'arrière de l'outil selon la figure 1.Figure 4 shows the head of the tool of Figure 1 in action during the cutting of a coating sheet against a simple support surface. FIG. 5 is a view of the rear of the tool according to FIG. 1.
La figure 6 représente le chariot curseur.Figure 6 shows the slider carriage.
La figure 7 représente un casse-lame.Figure 7 shows a breaker.
Comme le montrent les figures l et 2, l'outil 10 suivant l'invention, d'une longueur totale de 15 cm environ et d'une épaisseur de 1 cm environ, comprend un corps il dont la tête 12 est profilée pour présenter deux faces obliques 13 s'étendant de part et d'autre d'une fente 14 pour le passage de l'extrémité d'une lame 16 logée dans une rainure intérieure du corps 11. La fente 14 est positionnée de manière que la lame sorte exactement obliquement à l'extrémité frontale de l'arête 15 formée par la jointure des faces obliques 13 et dans l'alignement de cette arête. La lame 16 est du type à expulsion sans cran d'arrêt : elle est mue par un chariot curseur 17 et est avantageusement à segments séparables. Ces segments peuvent être cassés à l'aide du chariot 30 placé à l'arrière de l'outil. Le chariot curseur peut être déplacé dans une coulisse ouverte à un côté latéral du manche et parallèle à ce manche.As shown in Figures 1 and 2, the tool 10 according to the invention, with a total length of about 15 cm and a thickness of about 1 cm, comprises a body il whose head 12 is profiled to present two oblique faces 13 extending on either side of a slot 14 for the passage of the end of a blade 16 housed in an internal groove of the body 11. The slot 14 is positioned so that the blade comes out exactly obliquely at the front end of the edge 15 formed by the joining of the oblique faces 13 and in alignment with this edge. The blade 16 is of the expulsion type without stop notch: it is moved by a slider carriage 17 and is advantageously with separable segments. These segments can be broken using the carriage 30 placed at the rear of the tool. The slider carriage can be moved in a slide open to a lateral side of the handle and parallel to this handle.
On notera aussi, au niveau du manche, la présence d'un profil supérieur 20 essentiellement droit avec une dépression progressive 21 menant à une autre portion 22 droite antérieure, adjacente à la tête. Par ailleurs l'extrémité libre du manche présente avantageusement des arrondis 23. L'ensemble est ainsi particulièrement ergonomique.It will also be noted, at the level of the handle, the presence of an essentially straight upper profile 20 with a progressive depression 21 leading to another straight front portion 22, adjacent to the head. Furthermore the free end of the handle advantageously has rounded 23. The assembly is thus particularly ergonomic.
Lors de l'utilisation dans un angle les faces obliques 13 et l'arête 15 servent d'appuis qui permettent en un premier temps de marquer la feuille à découper dans l'angle et ensuite de maintenir la feuille entre elle et les surfaces de support durant la découpe.When used in a corner, the oblique faces 13 and the edge 15 serve as supports which firstly mark the sheet to be cut in the corner and then hold the sheet between it and the support surfaces. during cutting.
En effet, lorsque l'utilisateur fait glisser l'outil 10 dans l'angle formé par deux surfaces de support 18 et 19 comme représenté en figure 3, les faces d'appui 13 et l'arête d'appui 15 obligent la feuille de revêtement 25 à épouser correctement le profil de l'angle avant le passage de la lame coupante 16 dans l'alignement de l'arête d'appui 15. La feuille de revêtement peut ainsi être découpée de manière précise et régulière sans devoir recourir à un outil supplémentaire quelconque.In fact, when the user slides the tool 10 into the angle formed by two support surfaces 18 and 19 as shown in FIG. 3, the bearing faces 13 and the bearing edge 15 force the sheet of coating 25 to properly match the angle profile before the cutting blade 16 passes in alignment with the support edge 15. The covering sheet can thus be cut precisely and regularly without having to resort to any additional tool.
La figure 5 est une vue schématique de l'arrière de l'outil selon la figure 1. On distingue le casse-lame 30 sous la forme d'un curseur libre introduit dans la glissière, avec une fente 31 apte à recevoir un bout de lame pour la casser par pliage.FIG. 5 is a diagrammatic view of the rear of the tool according to FIG. 1. The blade breaker 30 can be distinguished in the form of a free cursor introduced into the slide, with a slot 31 capable of receiving a piece of blade to break it by folding.
La figure 6 représente le chariot curseur vu de côté (fig. 6a) , en plan (fig 6b) et, à la fig. 6c, selon la coupe AA. Le profil latéral est en I comme celui du coupe lame 30. Une face supérieure 29 est partiellement cannelée afin de faciliter le mouvement latéral du chariot à l'aide d'un doigt.Figure 6 shows the slider carriage seen from the side (fig. 6a), in plan (fig 6b) and, in fig. 6c, according to section AA. The lateral profile is in I like that of the blade cutter 30. An upper face 29 is partially grooved in order to facilitate the lateral movement of the carriage using a finger.
On distingue le tenon 26, prévu sur un bras s'étendant vers la tête de l'outil, qui s'adapte dans un trou prévu à l'extrémité intérieure de la lame afin de rendre le mouvement de la lame solidaire de celui du chariot curseur. On distingue également un ressort à lame 27 dont le centre arrondi est destiné à exercer une pression latérale sur une nervure (28, fig. 5) prévue dans la gorge, pression résultant en une friction suffisante pour stabiliser la position de la lame.There is a pin 26, provided on an arm extending towards the head of the tool, which fits into a hole provided at the inner end of the blade in order to make the movement of the blade integral with that of the carriage cursor. There is also a leaf spring 27 whose rounded center is intended to exert lateral pressure on a rib (28, fig. 5) provided in the groove, pressure resulting in sufficient friction to stabilize the position of the blade.
La figure 7 représente un casse-lame 30 avec une fente 31 , qui peut être retirée de la gorge. La fente 31 est destinée à recevoir la lame à couper par pliage selon des lignes de faiblesse prévues sur la lame. Bien entendu l'outil suivant l'invention peut également être utilisé contre une surface de support simple comme un couteau (cutter) classique. C'est ce que représente la figure 4.Figure 7 shows a breaker 30 with a slot 31, which can be removed from the groove. The slot 31 is intended to receive the blade to be cut by folding along lines of weakness provided on the blade. Of course the tool according to the invention can also be used against a simple support surface like a conventional knife (cutter). This is shown in Figure 4.
En outre le profil de la tête de l'outil suivant l'invention permet son utilisation aisée dans tous les sens de coupe (de gauche à droite, de droite à gauche, de haut en bas, de bas en haut) .In addition the profile of the head of the tool according to the invention allows its easy use in all cutting directions (from left to right, from right to left, from top to bottom, from bottom to top).
En résumé, l'invention propose notamment :In summary, the invention notably proposes:
- un outil pour découper une feuille de matière, , la tête du corps présentant deux faces obliques situées dans deux plans qui s'étendent de part et d'autre de la fente précitée à partir de la tête, lesdites faces obliques se joignant suivant une arête qui s'étend longitudinalement au plan de la lame, la lame coupante sortant obliquement de ladite tête à une extrémité de l'arête précitée et dans l'alignement de celle-ci.a tool for cutting a sheet of material, the head of the body having two oblique faces situated in two planes which extend on either side of the aforementioned slot from the head, said oblique faces joining in a edge which extends longitudinally to the plane of the blade, the cutting blade extending obliquely from said head at one end of the aforementioned edge and in alignment with the latter.
