Abstract

A removable automatic guide device for making perfectly straight cuts, comprising a plane guide (1) placed vertically beneath the jigsaw plate along the cutting axis. The base (2) and the plate fit into each other. The guide (1) extends up to the hole (5) and engages the cutting groove directly behind the tool to serve as an automatic rectilinear guide. The device is designed particularly for making self-guided straight-line cuts with a jigsaw.

Description

Dispositif amovible d'autoguidage rectiligne pour machine à scier ou à découper portative Removable rectilinear autoguiding device for portable sawing or cutting machine
La présente invention concerne un dispositif amovible d'autogui¬ dage pour effectuer des coupes rectilignes avec une machine à scier ou à découper portative, notamment avec une scie sauteuse.The present invention relates to a removable autogui¬ dage device for making rectilinear cuts with a portable sawing or cutting machine, in particular with a jigsaw.
Les dispositifs de guidage existants sont fondés sur un principe de barre, de règle ou de dérive.The existing guiding devices are based on a principle of bar, rule or drift.
Les dérives suivant antériorités n° DE 1 278 728 et n° US 4 051 597 du fait de leurs très faible longueurs n'assurent pas la fonction d'auto- guidage parce que la force linéaire nécessaire pour effectuer une coupe est supérieure à la pression que supportent lesdites dérives et par con- séquent n'empêchent pas un mouvement rotatif qui provoque une déviation de la trajectoire escomptée.Drifts following prior art No. 1 278 728 and No. US 4,051,597 by virtue of their very small lengths do not provide self-guiding function because the linear force necessary to perform the cutting is greater than the pressure supported by said drifts and therefore do not prevent a rotary movement which causes a deviation from the expected trajectory.
Les systèmes n° FR 2 490 137 avec barre ou règle guident la machine par maintien parallèle à l'aide d'un patin que l'utilisateur fait coulisser contre une surface parallèle à la trajectoire de l'outil de coupe. Il est par conséquent nécessaire d'exercer une pression sur le patin avec une main et pousser la machine vers l'avant avec l'autre. Cette position de travail pénalise la précision et la qualité du résultat. Par ailleurs il est impossible d'obtenir une coupe droite avec ces systèmes lorsque la surface où s'appuie le patin n'est pas rectiligne. D'autre part,l' écart entre la machine et le patin est sensiblement égal à la longueur de la règle ce qui de ce fait empêche de couper en une seule opération une surface en son centre si ce dernier est supérieur à la longueur de la règle. De plus l'état de surface de la coupe obtenu par l'ensemble des antério- rites est irrégulier et raboteux.Systems no . FR 2 490 137 with bar or rule guide the machine by holding it parallel using a shoe which the user slides against a surface parallel to the path of the cutting tool. It is therefore necessary to apply pressure to the shoe with one hand and push the machine forward with the other. This working position penalizes the precision and quality of the result. Furthermore, it is impossible to obtain a straight cut with these systems when the surface on which the shoe rests is not straight. On the other hand, the distance between the machine and the shoe is substantially equal to the length of the rule which therefore prevents a surface from being cut in a single operation at its center if the latter is greater than the length of the rule. In addition, the surface condition of the cut obtained by all of the forerunners is irregular and rough.
Le dispositif selon l'invention permet de remédier à ces inconvé¬ nients.The device according to the invention overcomes these drawbacks.
Il comporte en effet, selon une première caractéristique préférentielle de réalisation, une pièce plane positionnée perpendiculairement sous leIt indeed comprises, according to a first preferred characteristic of embodiment, a flat part positioned perpendicularly under the
FEUILLE DE REMP.LACE ENT plateau de la machine dans son axe de coupe. Le dispositif est composé d'autre part d'une semelle permettant un montage rapide sur chaque type de scie sauteuse sans modification préalable du plateau. Son fonctionnement consiste en ce que l'amorce de la coupe entraîne le guide directement derrière l'outil de coupe dans la rainure générée. La progression de la machine dans l'axe de coupe permet au guide de mainte¬ nir par autoguidage une trajectoire rectiligne.REPLACEMENT SHEET LACE ENT machine table in its cutting axis. The device is also composed of a sole allowing rapid assembly on each type of jigsaw without prior modification of the plate. Its operation consists in that the initiation of the cut drives the guide directly behind the cutting tool in the generated groove. The progression of the machine in the cutting axis allows the guide to maintain by self-guiding a rectilinear trajectory.
L'autoguidage est obtenu grâce à la longueur du guide qui est supérieure à la moitié de celle du plateau, permettant à l'utilisateur d'effectuer une coupe rectiligne, sans dévier de la trajectoire escomptée tout au long de l'opération. L'épaisseur du guide sensiblement inférieure à celle de la rainure, et la longueur de celui-ci sufisament importante, empêchent la rotation de l'ensemble et assurent la précision de 1'autoguidage.Autoguiding is obtained thanks to the length of the guide which is greater than half that of the plate, allowing the user to make a rectilinear cut, without deviating from the expected trajectory throughout the operation. The thickness of the guide appreciably less than that of the groove, and the length of this sufisament important, prevent the rotation of the assembly and ensure the accuracy of the autoguiding.
Selon des modes particuliers de réalisation : - le guide peut être une seule pièce planeAccording to particular embodiments: - the guide can be a single flat piece
- il peut s'adapter au plateau de la machine par le biais de deux enco¬ ches- it can be adapted to the machine tray by means of two notches
- le guide peut être discontinu- the guide may be discontinuous
- le maintien du guide peut être obtenu à l'aide de rebords sur la se- melle exerçant une pression sur le plateau- the support of the guide can be obtained by means of flanges on the sole exerting pressure on the plate
Les dessins annexés illustrent l'invention:The accompanying drawings illustrate the invention:
- Les figures 1 , 2, 3 et 4 représentent en plusieurs vues le dispositif selon l'invention- Figures 1, 2, 3 and 4 show in several views the device according to the invention
- Les figures 5 et 6 représentent une variante de ce dispositif- Figures 5 and 6 show a variant of this device
En référence aux figures 1, 2, 3 et 4 le dispositif comporte un guide (1) de forme plane positionné perpendiculairement sous le plateau (3) de la machine dans l'axe de coupe.Referring to Figures 1, 2, 3 and 4 the device comprises a guide (1) of planar shape positioned perpendicularly under the plate (3) of the machine in the cutting axis.
FEUILLE DE REMP.LACEMEIMT Le dispositif est composé d'autre part d'une semelle (2) qui permet un montage de l'ensemble sur le plateau (3) par emboîtement. Le guide (1) s'étend jusqu'au trou (5). De ce fait l'amorce de coupe entraîne le guide (1) directement derrière l'outil de coupe dans la rainure (4; générée. La progression du dispositif dans l'axe de coupe permet au guide (1) de maintenir par autoguidage une trajectoire rectiligne. Dans la forme de réalisation selon les figures 5 et 6 le guide (7) composé d'une pièce plane s'adapte au plateau (2) de la machine par le biais de deux encoches (6).REPLACEMENT SHEET LACEMEIMT The device is also composed of a sole (2) which allows mounting of the assembly on the plate (3) by interlocking. The guide (1) extends to the hole (5). Therefore the cutting initiator drives the guide (1) directly behind the cutting tool in the groove (4; generated. The progression of the device in the cutting axis allows the guide (1) to maintain by autoguiding In the embodiment according to FIGS. 5 and 6, the guide (7) composed of a flat part adapts to the plate (2) of the machine by means of two notches (6).
