Abstract

The subject of the invention concerns a blade-guide device for a mitre box or similar. It is constituted by an independent detachable guide adapting to the saw blade 5 and to its frame and integrating with its devices for rolling and stabilising on the guide grooves of the receiving mitre box. It is intended for obtaining cutting regularity and for preserving the guidance cut-outs from clumsy saw cuts.

Description

L'objet de l'invention concerne un dispositif de guide lame pour boîte à onglets ou similaires. The object of the invention relates to a blade guide device for a miter box or the like.

Il est destiné à obtenir une régularité de coupe et à préserver les entailles de guidage, des coups de scie malencontreux. It is intended to obtain a regularity of cut and to preserve the notches of guide, of the inadvertent saws.

Les boites à onglets Courantes comportent des canaux de guidage constitués par des fentes dont la largeur doit être supérieure à l'épaisseur de la lame de scie qui doit se déplacer sans frottement gênant son maniement, cet entregent provoque alors l'usure rapide des parois, un certain flottement de direction, et parfois même suivant la résistance de la pièce à séparer un flambage de la lame. The current miter boxes have guide channels formed by slots whose width must be greater than the thickness of the saw blade which must move without friction hampering its handling, this air gap then causes rapid wear of the walls, a certain floating direction, and sometimes even depending on the resistance of the part to separate buckling of the blade.

Le dispositif suivant l'invention supprime ces inconvénients en permettant la suppression des frottements de la lame contre les parois des fentes de guidage et tout mouvement susceptible, soit de freiner la lame, soit d'endommager les rainures de guidage ou encore de nuire à la netteté et la régularité du trait de coupe. The device according to the invention eliminates these drawbacks by allowing the friction of the blade against the walls of the guide slots to be eliminated and any movement liable either to brake the blade or to damage the guide grooves or even to harm the sharpness and regularity of the cutting line.

Il est constitué par un guide amovible indépendant s'adaptant à la lame de la scie ainsi qu'à sa monture et s'inté; grant avec ses organes de roulement et de stabilisation sur les rainures de guidage de la boite à onglets réceptrice. It consists of an independent removable guide which adapts to the saw blade as well as its frame and is integrated; grant with its rolling and stabilizing members on the guide grooves of the receiving miter box.

Sur les dessins annexés, donnés à titre d ' exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 montre vu en perspective le support de lame.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows a perspective view of the blade support.

La figure 2 représente vu en coupe longitudinale et en plan le même objet. Figure 2 shows seen in longitudinal section and in plan the same object.

Les figures 5, 6 montrent vu en per#spective et en plan la boîte à onglets adaptée au porte lame. Figures 5, 6 show seen in per # spective and plan the miter box adapted to the blade holder.

Le guide lame figures 1, 2, 3, 4 est constitué par une monture formée par les faces symétriques 1, 2.  The blade guide in Figures 1, 2, 3, 4 is constituted by a frame formed by the symmetrical faces 1, 2.

Chaque élément de monture comporte une partie supérieure horizontale avec évidements internes 3, 4 formant logement 4', dans lequel coulisse la monture 5 de scie. Each frame element has a horizontal upper part with internal recesses 3, 4 forming a housing 4 ′, in which the saw frame 5 slides.

Le parement supérieur est muni de moyen de fixation 6, 7, 8, 9 du guide lame étant précisé que la partie inférieure est également immobilisée par des éléments équivalents. The upper facing is provided with fixing means 6, 7, 8, 9 of the blade guide, it being specified that the lower part is also immobilized by equivalent elements.

Les montants verticaux solidaires des parties supérieures 1, 2 comportent des rouleaux de guidage 10, 11, 12, 13. The vertical uprights integral with the upper parts 1, 2 comprise guide rollers 10, 11, 12, 13.

La base forme un évasement 14 libérant la partie coupante ou denturée de la scie. The base forms a flare 14 freeing the cutting or serrated part of the saw.

Des tenons 15, 16 débordent les parements externes des montants arrières 17, 18. Ils sont destinés à pénêtrer dans les fentes latérales 19, 20 situées de part et d'autre des rainures de guidages 23, 24,etc... des boîtes à onglets 21 (Fig 5, 6) Ils constituent des talons d'ancrage positionnant et immobilisant dans sa position fonctionnelle le guide lame. Tenons 15, 16 extend beyond the outer facings of the rear uprights 17, 18. They are intended to penetrate into the lateral slots 19, 20 located on either side of the guide grooves 23, 24, etc. of the boxes tabs 21 (Fig 5, 6) They constitute anchoring heels positioning and immobilizing in its functional position the blade guide.

La monture figures 1, 2, 3, 4 a une section en U ou étrier avec longeron 9 et montant 17, 18, 17', 18' jointifs à leur base 22 obturant l'espace de débattement 14 où se déplace la partie coupante de la scie. The frame in Figures 1, 2, 3, 4 has a U-shaped section or stirrup with spar 9 and upright 17, 18, 17 ', 18' contiguous to their base 22 closing the clearance space 14 where the cutting part of the the saw.

La boîte à onglets adaptée au porte lame (Fig 1) est formée par une superstructure verticale comportant les fentes de guidage 23, 24 orientées suivant les dispositions classiques, mais avec rainures latérales 19, 20 recevant les tenons de guidage et d'ancrage 15, 16. The miter box adapted to the blade holder (FIG. 1) is formed by a vertical superstructure comprising the guide slots 23, 24 oriented according to the conventional arrangements, but with lateral grooves 19, 20 receiving the guide and anchoring studs 15, 16.

Sa surface de travail est munie de traits de séparation 25, 26, 27, 28 situés sous le niveau de la partie portante de la pièce à séparer pour permettre le passage de la lame en fin de sciage. Its working surface is provided with separation lines 25, 26, 27, 28 located below the level of the bearing part of the part to be separated to allow the blade to pass at the end of sawing.

Des séries de perforations orientées 29, 30 reçoivent les plots d'immobilisation des pièces à séparer formés par un corps cylindrique 31 avec axe excentré 32 et bras de pression 33.  Series of oriented perforations 29, 30 receive the immobilization pads of the parts to be separated formed by a cylindrical body 31 with eccentric pin 32 and pressure arm 33.

Des encoches 34, 35 reçoivent des pièces de fixation de la boîte sur une table de travail.La monture 1, 2 peut être
métallique ou en résine synthétique et, est adaptable à tous types de boîte à onglets qui devront comporter de part et d'autre des fentes de guidage, des rainures perpendiculaires immobilisant la monture pendant le coulissement de la scie.Notches 34, 35 receive fasteners for the box on a work table. The mount 1, 2 can be
metal or synthetic resin and is adaptable to all types of miter box which must have on both sides of the guide slots, perpendicular grooves immobilizing the frame during the sliding of the saw.

Cette dernière stabilisée, guidée sera structurée quelle que soit la souplesse de la lame et permettra d'utiliser quelle que #soit la dureté de la pièce à séparer, un trait de coupe parfaitement régulier. The latter stabilized, guided will be structured regardless of the flexibility of the blade and will allow using whatever the hardness of the part to be separated, a perfectly regular cutting line.

Une précision absolue sera obtenue, ce qui donnera la possibilité même pour des travaux de bricolage de réaliser des travaux les plus délicats avec une régularité totale des faces séparées. Absolute precision will be obtained, which will give the possibility even for DIY work to carry out the most delicate work with total regularity of the separate faces.

L'effort de l'usager sera attenué, de sorte que la précision de l'outil quelle que soit sa qualité s ' ajoute une sou- plesse de mouvement inégalée. The effort of the user will be attenuated, so that the precision of the tool, whatever its quality, adds an unequaled flexibility of movement.

Enfin, les rainures de guidage des boîtes à onglets ne seront plus déformées par les dégradations inévitables provoquées par l'irrégularité de sciage. Finally, the guide grooves of the miter boxes will no longer be deformed by the inevitable degradations caused by sawing irregularity.

Le guide lame indépendant de la boîte à onglets est interchangeable et s ' adapte à toutes les lames de scie, mais préférentiellement à celles pourvues d'une monture. The independent blade guide of the miter box is interchangeable and adapts to all saw blades, but preferably to those provided with a frame.

Toutefois les formes, dimensions et dispositions des différents éléments, pourront varier dans la limite des équivalents, comme d ' ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de 1' inven- tion qui vient d'être décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, like the materials used for their manufacture, without changing the general conception of the invention which has just been described.
