Abstract

The cutting guide has a rectangular plate (1) slightly raised on four feet, supporting two rigid slides (4) that support and guide the sole of the saw. The slides are fixed to raised edges (3) on the rectangular plate, square to the plate edges. One slide is fixed and the other can be adjusted to the width of the sole of the saw. The wood to be cut is held between the raised edges of the plate.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un dispositif permettant d'effectuer des coupes rectilignes, notamment à 90 , avec une scie électrique portative ( sauteuse ou circulaire), coupes droites ou obliques (lame inclinée).  The present invention relates to a device for making rectilinear cuts, in particular at 90, with a portable electric saw (jig or circular), straight or oblique cuts (inclined blade).

De nos jours, la plupart des bricoleurs sont équipés de telles scies électriques, mais désespèrent de pouvoir effectuer des coupes précises, rectilignes et d'équerre...  Nowadays, most DIY enthusiasts are equipped with such electric saws, but despair of being able to make precise, rectilinear and square cuts ...

Certains fixent leur scie circulaire sur des tables spécialement conçues, mais ce système présente nombre d'inconvénients : coût important, encombrement, immobilisation de la scie, dangerosité de la lame en saillie...  Some fix their circular saw on specially designed tables, but this system has a number of disadvantages: high cost, size, immobilization of the saw, dangerousness of the projecting blade ...

Le dispositif selon l'invention échappe à tous ces inconvénients.  The device according to the invention escapes all these drawbacks.

La figure 1 représente le dispositif, lequel se compose : - d'un plateau rectangulaire (1), qui peut consister en une plaque de contreplaqué, surélevé de quelques centimètres grâce à quatre pieds (2) -de deux rebords (3) : deux tasseaux de section carrée (par exemple 34x34 mm) collés sur le dessus de ce plateau, le long de ses côtés étroits, -de deux coulisses rigides (4) : par exemple tasseaux rainurés sur leur profil se faisant face de façon à servir de support et de guide à la semelle de la scie électrique, entre lesquels elle coulissera. Ces coulisses sont fixées, à chaque bout du plateau et à 90 , sur les rebords (3) : l'une est fixée à demeure, l'autre par un moyen amovible (par exemple boulons et écrous associés à des trous oblongs) afin de pouvoir s'adapter à la largeur de la semelle de la scie utilisée.  Figure 1 shows the device, which consists of: - a rectangular plate (1), which can consist of a plywood plate, raised a few centimeters by four feet (2) - two ledges (3): two battens of square section (for example 34x34 mm) glued on the top of this tray, along its narrow sides, - two rigid slides (4): for example grooved battens on their profile facing each other so as to serve as a support and guide to the sole of the electric saw, between which it will slide. These slides are fixed, at each end of the tray and 90, to the edges (3): one is fixed permanently, the other by removable means (for example bolts and nuts associated with oblong holes) in order to be able to adapt to the width of the base of the saw used.

La pièce à scier repose sur le plateau (1), plaquée contre l'un des rebords (3) pour une coupe à 90 , et est fermement maintenue par un serrejoint (utilisable grâce à la surélévation du plateau)
Le mode opératoire diffère selon le type de scie utilisée :
SCIE CIRCULAIRE : on engage d'abord la semelle dans les coulisses (4) puis l'on traverse tout le plateau, sciant le premier rebord (3), entamant ensuite superficiellement la surface du plateau, sciant enfin le second rebord (3) : le chemin de coupe est ainsi constitué. La traversée du premier rebord (3) provoque le relèvement du carter inférieur de la lame de scie. The piece to be sawed rests on the plate (1), pressed against one of the flanges (3) for a 90 cut, and is firmly held by a clamp (usable thanks to the elevation of the plate)
The procedure differs depending on the type of saw used:
CIRCULAR SAW: we first engage the sole in the slides (4) then we cross the entire plate, sawing the first edge (3), then surface cutting the surface of the plate, finally sawing the second edge (3): the cutting path is thus formed. The crossing of the first edge (3) causes the raising of the lower casing of the saw blade.

SCIE SAUTEUSE : la lame de scie se déplace d'un rebord (3) à l'autre, mais côtés intérieurs, sans les scier. Le plateau (1) est évidé le long de l'axe de coupe pour ne pas gêner les mouvements verticaux de la lame de scie. Une butée fixée sur le rebord (3) de fin de course empêche le sciage inopiné de

celui-ci (une légère entame permettra toutefois un positionnement précis de la pièce à scier) Le sciage à 450 s'effectue en positionnant la pièce sur la ligne des 45 tracée sur le plateau. On peut aussi imaginer un positionnement à 450 des coulisses (4) pour une spécificité de coupes d'onglets.JIGSAW: the saw blade moves from one edge (3) to the other, but on the inside, without sawing. The plate (1) is hollowed out along the cutting axis so as not to hinder the vertical movements of the saw blade. A stop fixed on the end-of-travel flange (3) prevents unexpected sawing from

the latter (a slight opening will however allow precise positioning of the part to be sawn) Sawing at 450 is carried out by positioning the part on the line of 45 traced on the plate. One can also imagine a positioning at 450 of the slides (4) for a specificity of miter cuts.

Claims (4)

REVENDICATIONS 1) Dispositif permettant d'effectuer des coupes rectilignes, notamment à 900, avec une scie électrique portative (sauteuse ou circulaire), caractérisé en ce qu'il comporte un plateau (1) légèrement surélevé par quatre pieds (2), que traversent deux coulisses rigides (4) destinées à soutenir et guider la semelle de la scie, lesquelles coulisses reposent à chaque extrémité du plateau sur un rebord (3) avec lequel elles forment un angle droit (ou de 45 pour une spécificité de coupe d'onglets). 1) Device for making rectilinear cuts, especially at 900, with a portable electric saw (jig or circular), characterized in that it comprises a plate (1) slightly raised by four feet (2), which two pass through rigid slides (4) intended to support and guide the base of the saw, which slides rest at each end of the plate on a flange (3) with which they form a right angle (or 45 for a specificity of cutting of tabs) . 2) Dispositif selon la revendication 1 caractérisé par le fait que l'une des coulisses (4) est fixée à demeure et que la seconde est fixée par un moyen amovible (boulons et écrous associés à des trous oblongs) permettant un ajustement de l'écartement entre les deux coulisses en fonction de la largeur de la semelle de la scie utilisée.  2) Device according to claim 1 characterized in that one of the slides (4) is fixed permanently and that the second is fixed by removable means (bolts and nuts associated with oblong holes) allowing adjustment of the spacing between the two slides depending on the width of the base of the saw used. 3) Dispositif selon les revendications 1 et 2 caractérisé par le fait que la scie circulaire aménage son chemin de coupe en sciant les deux rebords (3) et en entamant superficiellement la surface du plateau (1) ; la traversée du premier rebord provoquant le relèvement du carter inférieur de la lame de scie.  3) Device according to claims 1 and 2 characterized in that the circular saw arranges its cutting path by sawing the two flanges (3) and by superficially entering the surface of the plate (1); the crossing of the first edge causing the raising of the lower casing of the saw blade. 4) Dispositif selon l'une quelconque des revendications précédentes, caractérisé par le fait que le plateau (1) est évidé le long de l'axe de coupe de la scie sauteuse, entre les rebords (3), pour ne pas gêner les mouvements verticaux de la lame. 4) Device according to any one of the preceding claims, characterized in that the plate (1) is hollowed out along the cutting axis of the jigsaw, between the edges (3), so as not to hinder the movements vertical of the blade.
