Description

Support de feuillure autoréglable pour machine à couper en onglet notamment de moulures d'encadrement.Self-adjusting rebate support for miter cutting machines, in particular for frame moldings.

L'invention se situe dans le domaine technique de l'encadrement et vise à perfectionner une machine à couper en onglet des moulures grâce à un support de feuillure autoréglable .The invention lies in the technical field of framing and aims to improve a miter cutting machine for moldings using a self-adjusting rebate support.

Il est bien connu d'équiper de telles machines avec des supports de feuillures montés coulissant sur deux guides orientés à 45° par rapport au plan de la moulure. Ces supports qui se glissent sous la feuillure ont pour fonction de soutenir la moulure lors de l'opération de coupe, afin d'éviter son basculement et une coupe imparfaite. Mais il faut pour cela que le talon horizontal du support de feuillure soit ajusté sous l'angle rentrant de la feuillure et contre celle-ci, aussi parfaitement que possible sans soulever la moulure. Jusqu'à présent des boutons moletés associés au mécanisme mobile que constitue le support de feuillure, permettent de lever ou d'abaisser le talon du support pour le placer à la bonne place contre la moulure. Cette opération n'est pas toujours aisée pour l'utilisateur qui, si la moulure n'est pas correctement maintenue sur une table de travail, se traduira par son soulèvement au-dessus de la table. Ce mécanisme manque donc de sensibilité et impose à l'utilisateur des tâtonnements avant de bloquer le support de feuillure à bonne hauteur.It is well known to equip such machines with rebate supports mounted to slide on two guides oriented at 45 ° relative to the plane of the molding. These supports which slide under the rebate have the function of supporting the molding during the cutting operation, in order to avoid its tilting and an imperfect cut. But for this it is necessary that the horizontal heel of the rebate support is adjusted under the re-entrant angle of the rebate and against it, as perfectly as possible without lifting the molding. Until now knurled buttons associated with the movable mechanism that constitutes the rebate support, allow to raise or lower the heel of the support to place it in the right place against the molding. This operation is not always easy for the user who, if the molding is not properly maintained on a work table, will result in its lifting above the table. This mechanism therefore lacks sensitivity and requires the user to trial and error before locking the rebate support at the correct height.

La Demanderesse entend remédier à ces inconvénients en proposant un support de feuillure autoréglable, de maniement simple, grâce auquel le support est toujours correctement placé par rapport à la feuillure, sans déplacement de celle-ci .The Applicant intends to remedy these drawbacks by proposing a self-adjusting rebate support, of simple handling, by means of which the support is always correctly placed relative to the rebate, without displacement of the latter.

L'invention a donc pour objet un support de feuillure pour machine à couper en onglet notamment de moulures d'encadrement, comportant une butée de fond de feuillure en forme d'équerre montée sur une tige déplaçable sur ledit support et comportant des moyens de verrouillage en hauteur de la tige sur le support . L'invention se caractérise par le fait que laThe subject of the invention is therefore a rebate support for a miter cutting machine, in particular for framing moldings, comprising a right-angled rebate bottom stop mounted on a rod movable on said support and comprising locking means. in height of the rod on the support. The invention is characterized in that the

-tige est montée coulissante sur le support de feuillure et associée à un ressort de rappel placé entre son extrémité et la base du support, la tige étant verrouillée en hauteur sur ledit support par un mécanisme de blocage .rod is slidably mounted on the rebate support and associated with a return spring placed between its end and the base of the support, the rod being locked in height on said support by a blocking mechanism.

Plus précisément, le mécanisme de blocage est constitué d'un collier de - serrage coulissant sur la tige dont les deux ailes sont percées d'orifices pour le passage de l'axe d'une manette de blocage. Le fonctionnement du support de feuillure et les avantages qu'il procure ressortiront de la description qui va suivre d'un mode préférentiel de réalisation dans lequel il est fait référence aux dessins annexés qui représentent : Figure 1, une vue en perspective d'une machine à couper en onglet équipée de supports de feuillure selon 1 ' invention .More precisely, the blocking mechanism consists of a clamping collar sliding on the rod, the two wings of which are pierced with orifices for the passage of the axis of a blocking handle. The operation of the rebate support and the advantages which it provides will emerge from the description which follows of a preferred embodiment in which reference is made to the appended drawings which represent: FIG. 1, a perspective view of a machine to be cut into a miter fitted with rebate supports according to the invention.

Figure 3, une vue en coupe à plus grande échelle selon III-III de la figure 2,FIG. 3, a sectional view on a larger scale according to III-III of FIG. 2,

Figures 4 à 6 des vues en élévation de la machine dans des phases successives de fonctionnement.Figures 4 to 6 are views in elevation of the machine in successive operating phases.

La figure 1 montre une table de travail 6 connue en soi, portant un jeu de butées pivotantes 2 servant d'appui à la moulure 3 devant être coupée d'onglet. Pour cela des fers de coupe non représentés sont placés le long de deux guides horizontaux 4 orientés à 45° par rapport aux butées 2. Chacun de ces guides 4 est creusé d'une gorge 5 servant au coulissement d'un support de feuillure désigné dans son ensemble par la référence 1 et représenté plus en détail à la figure 2. le support de feuillure 1 est monté sur un coulisseau 10 qui se place dans la gorge 5, coulisseau auquel il est fixé par une vis 11. Le support 1 se développe verticalement au-dessus du coulisseau et sert de logement à une tige coulissante 12 solidaire d'une butée de fond de feuillure 13 en forme d'équerre. Un ressort de rappel 14 est intercalé entre l'extrémité de la tige 12 et la base du support 1. A la partie supérieure dudit support est monté et •fixé par une vis 19 un collier de serrage 15 également visible à la figure 3, collier dont les deux ailes (15a, 15b) sont percées d'orifices 16 pour le passage de l'axe d'une manette de blocage 17 visible à la figure 1. L'extrémité du collier est pourvue d'une ouverture 18 qui est engagée sur la tige 12. Celle-ci se déplace librement dans l'ouverture tant que les deux ailes (15a, 15b) du collier n'ont pas été serrées par la manette. Dans la position illustrée aux figures 1 et 4, la moulure 3 est en appui contre les butées 2 et les supports de feuillure 1 en sont écartés .Figure 1 shows a work table 6 known per se, carrying a set of pivoting stops 2 serving to support the molding 3 to be cut miter. For this, cutting irons not shown are placed along two horizontal guides 4 oriented at 45 ° relative to the stops 2. Each of these guides 4 is hollowed out with a groove 5 used for sliding a rebate support designated in its assembly by the reference 1 and shown in more detail in Figure 2. the rebate support 1 is mounted on a slide 10 which is placed in the groove 5, slide to which it is fixed by a screw 11. The support 1 develops vertically above the slide and serves as a housing for a sliding rod 12 secured to a rebate bottom stop 13 in the form of a square. A return spring 14 is interposed between the end of the rod 12 and the base of the support 1. At the upper part of said support is mounted and • fixed by a screw 19 a clamp 15 also visible in Figure 3, collar whose two wings (15a, 15b) are pierced with holes 16 for the passage of the axis of a locking lever 17 visible in FIG. 1. The end of the collar is provided with an opening 18 which is engaged on the rod 12. The latter moves freely in the opening as long as the two wings (15a, 15b) of the collar were not tightened by the lever. In the position illustrated in FIGS. 1 and 4, the molding 3 bears against the stops 2 and the rebate supports 1 are spaced therefrom.

La première opération pour l'utilisateur consiste à desserrer la manette de blocage 17 qui autorise l'écartement des ailes du collier de serrage 15 et libère ainsi la tige coulissante 12.The first operation for the user consists in loosening the locking handle 17 which allows the wings of the clamp 15 to spread apart and thus releases the sliding rod 12.

On peut alors enfoncer cette tige 12 à l' encontre de la force du ressort de rappel 14, comme le montre la figure 5. Ainsi la butée de fond de feuillure 13 vient en position basse, et en agissant horizontalement dans le sens de la flèche, on déplace le support de feuillure 1, pour que la butée 13 se glisse sous la moulure 3. Durant ce mouvement, on maintient manuellement la moulure contre les butées 2. Puis on relâche la pression sur la tige 12, que le ressort 14 repousse vers le haut jusqu'à ce que la butée 13 vienne s'appliquer contre la partie supérieure de la feuillure, la moulure étant toujours maintenue en place manuellement. Il reste alors à l'utilisateur à bloquer la tige 12 dans cette position à l'aide de la manette de blocage 17, comme le représente la figure 6. Bien entendu on manipule les deux supports de feuillure 1 de la même façon.We can then push this rod 12 against the force of the return spring 14, as shown in Figure 5. Thus the rabbet bottom stop 13 comes in the low position, and acting horizontally in the direction of the arrow , the rebate support 1 is moved, so that the stop 13 slides under the molding 3. During this movement, the molding is manually held against the stops 2. Then the pressure is released on the rod 12, that the spring 14 pushes back upwards until the stop 13 comes to bear against the upper part of the rebate, the molding still being held in place manually. It then remains for the user to lock the rod 12 in this position using the locking handle 17, as shown in FIG. 6. Of course, the two rebate supports 1 are handled in the same way.

On a ainsi un moyen automatique de régler à bonne hauteur un support de feuillure par rapport à une moulure d'encadrement, sans que l'utilisateur soit amené à des ajustements particuliers et fastidieux. There is thus an automatic means of adjusting the rebate support to the correct height with respect to a frame molding, without the user having to make any particular and tedious adjustments.
