Description

La présente invention concerne un dispositif de protection s'adaptant sur une dégauchisseuse à bois, avec un pont protecteur mobile disposé au-dessus de la table de la machine et permettant de couvrir la partie de l'arbre porte-outils située à l'avant du guide-pièce, des moyens étant prévus pour régler le pont en hauteur pour le passage du bois à dégauchir et pour lui permettre de se déplacer verticalement en restant parallèle à la table.The present invention relates to a protective device adapting to a wood jointer, with a movable protective bridge arranged above the machine table and making it possible to cover the part of the tool-holding shaft located at the front. of the workpiece guide, means being provided for adjusting the height of the bridge for the passage of the wood to be planed and for allowing it to move vertically while remaining parallel to the table.

Lorsqu'une pièce de bois doit être dégauchie sur ce genre de machine, on la fait passer sous le pont protecteur qui doit donc occuper une position réglée en hauteur en fonction de l'épaisseur de la pièce de bois. Lorsque cette pièce est ramenée en arrière afin de subir ensuite un deuxième passage sur les outils, elle passe sur le pont en appliquant ce dernier sur la table de la machine, donc en l'abaissant. Le pont protecteur doit ensuite revenir à la hauteur pré-réglée pour permettre le deuxième passage de la pièce de bois.When a piece of wood must be planed on this kind of machine, it is passed under the protective bridge which must therefore occupy a position adjusted in height according to the thickness of the piece of wood. When this part is brought back in order to then undergo a second passage on the tools, it passes over the bridge by applying the latter on the machine table, therefore by lowering it. The protective bridge must then return to the preset height to allow the second passage of the piece of wood.

Les dispositifs de protection connus, du type ici considéré, utilisent pour contrôler le déplacement du pont protecteur soit des parallélogrammes déformables ou des compas, soit des guidages rectilignes qui n'assurent pas à eux seuls, et séparément, une rigidité suffisante et un bon contrôle du-déplacement automatique du pont en direction verticale.Known protection devices, of the type considered here, use to control the movement of the protective bridge either deformable parallelograms or compasses, or rectilinear guides which do not alone and separately provide sufficient rigidity and good control automatic displacement of the bridge in vertical direction.

La présente invention remédie à ces inconvénients, en fournissant un dispositif procurant une grande rigidité, une construction compacte et simple, et un bon contrôle du déplacement automatique du pont protecteur en direction verticale.The present invention overcomes these drawbacks by providing a device providing great rigidity, a compact and simple construction, and good control of the automatic movement of the protective bridge in the vertical direction.

A cet effet, dans le dispositif de protection pour dégauchisseuse selon la présente invention, le pont protecteur est maintenu par un élément comportant un guidage rectiligne en direction sensiblement verticale, combiné à un guidage par au moins deux leviers reliés entre eux par au moins un axe d'articulation intermédiaire, un levier étant articulé par un axe mobile à l'élément de maintien du pont et un autre levier étant articulé par un axe fixe à un support solidaire du bâti de la dégauchisseuse.To this end, in the protection device for a jointer according to the present invention, the protective bridge is held by an element comprising a straight guide in a substantially vertical direction, combined with a guide by at least two levers connected to each other. by at least one intermediate articulation axis, a lever being articulated by a movable axis to the bridge holding element and another lever being articulated by a fixed axis to a support integral with the frame of the jointer.

Le dispositif selon l'invention se caractérise ainsi par la combinaison d'un guidage rectiligne et d'un guidage complémentaire au moyen de leviers articulés, assurant une liaison entre l'élément mobile qui maintient le pont et un support fixe.The device according to the invention is thus characterized by the combination of a rectilinear guide and a complementary guide by means of articulated levers, ensuring a connection between the mobile element which holds the bridge and a fixed support.

Selon une forme de réalisation préférentielle, le pont protecteur est fixé, par l'intermédiaire de son élément de maintien, au sommet d'une colonne déplaçable verticalement dans un guide de coulissement appartenant au support solidaire du bâti de la dégauchisseuse.According to a preferred embodiment, the protective bridge is fixed, by means of its holding element, at the top of a column movable vertically in a sliding guide belonging to the support integral with the frame of the jointer.

- Dans ce cas les leviers peuvent comprendre simplement un premier levier articulé par un premier axe soit directement à l'élément de maintien du pont protecteur, soit à l'extrémité inférieure de la colonne, et un second levier articulé au premier levier par un deuxième axe et articulé au support précité par un troisième axe ; les deux leviers forment ainsi une disposition en "compas". Dans une variante, le levier articulé par un axe à l'élément de maintien du pont et le levier articulé par un axe au support solidaire du bâti de la dégauchisseuse sont liés entre eux au moyen de deux autres leviers articulés aux-premiers, et constituant avec ceux-ci un système articulé genre "parallélogramme déformable".- In this case the levers may simply comprise a first lever articulated by a first axis either directly to the holding element of the protective bridge, or at the lower end of the column, and a second lever articulated to the first lever by a second axis and articulated to the aforementioned support by a third axis; the two levers thus form a "compass" arrangement. In a variant, the lever articulated by an axis to the bridge holding element and the lever articulated by an axis to the support integral with the frame of the jointer are linked together by means of two other levers articulated to the former, and constituting with these an articulated system like "deformable parallelogram".

Les leviers permettent en outre un contrôle aisé du réglage en hauteur du pont protecteur, en prévoyant une came-butée rotative munie d'un levier de manoeuvre et coopérant avec l'un des leviers précités de manière à limiter le déplacement vers le haut du pont sous l'effet d'un ressort de rappel. Ce ressort de rappel du pont peut être logé dans la colonne mobile verticalement de manière à tendre à la faire monter avec le pont. il peut aussi appliquer son effort, dans le sens convenable, sur l'un des leviers ou sur l'un des axes d'articulation.The levers also allow easy control of the height adjustment of the protective bridge, by providing a rotary stop cam provided with an operating lever and cooperating with one of the aforementioned levers so as to limit the upward movement of the bridge. under the effect of a return spring. This return spring of the bridge can be housed in the vertically movable column so as to tend to raise it with the bridge. he can also apply his effort, in the proper direction, on one of the levers or on one of the axes of articulation.

De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, quelques formes de réalisation de ce dispositif de protection pour dégauchisseuse :

  • Les figures 1 et 2 représentent, en vue de profil, un dispositif de protection conforme à l'invention, dans deux positions de réglage distinctes ;
  • Les figures 3 à 8 sont des vues très schématiques illustrant des variantes de ce dispositif, avec diverses dispositions de leviers et d'axes.
  • Le dispositif représenté sur les figures 1 et 2 comporte un support (1) fixé au bâti de la dégauchisseuse dont sont indiqués, très sommairement, la table (2) et l'arbre porte-outils (3) affleurant la table (2).
  • Le support (1) comporte une partie (4) servant de guide en coulissement pour une colonne (5) mobile verticalement. Le pont protecteur (6) est fixé au sommet de la colonne (5) par une pièce intermédiaire (7).
In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing showing, by way of nonlimiting examples, some embodiments of this protection device for jointer:
  • Figures 1 and 2 show, in side view, a protective device according to the invention, in two separate adjustment positions;
  • Figures 3 to 8 are very schematic views illustrating variants of this device, with various arrangements of levers and axes.
  • The device shown in Figures 1 and 2 comprises a support (1) fixed to the frame of the jointer which are indicated, very briefly, the table (2) and the tool shaft (3) flush with the table (2).
  • The support (1) comprises a part (4) serving as a sliding guide for a column (5) movable vertically. The protective bridge (6) is fixed to the top of the column (5) by an intermediate piece (7).

Une extrémité d'un premier levier (8) est articulée par un axe horizontal (9) à l'ensemble colonne (5) - pont (6) - pièce intermédiaire (7). L'autre extrémité du premier levier (8) est articulée par un axe horizontal (10) à une extrémité d'un second levier (11), dont la deuxième extrémité est articulée par un axe horizontal (12) au support (1).One end of a first lever (8) is articulated by a horizontal axis (9) to the column (5) - bridge (6) - intermediate piece (7) assembly. The other end of the first lever (8) is articulated by a horizontal axis (10) to one end of a second lever (11), the second end of which is articulated by a horizontal axis (12) to the support (1).

Un ressort de rappel (13), logé dans la colonne (5), tend à faire monter cette colonne avec le pont (6).A return spring (13), housed in the column (5), tends to raise this column with the bridge (6).

Une came-butée (14) est montée tournante sur le support (1) autour d'un axe (15) situé à l'intérieur de l'angle formé par les deux leviers (8,11). Un levier de manoeuvre (16) solidaire de la came-butée (14) permet sa commande en rotation.A stop cam (14) is rotatably mounted on the support (1) around an axis (15) located inside the angle formed by the two levers (8,11). An operating lever (16) integral with the cam-stop (14) allows its rotation control.

Si le passage d'une pièce de bois au retour, ou une autre cause accidentielle, tend à appuyer sur le pont (6), celui-ci viendra plaquer sur la table (2) de la dégauchisseuse, la colonne (5) descendant par rapport à son guide (4) en comprimant le ressort de rappel (13). Ensuite le pont (6) reprend sa position initiale sous la poussée de ce ressort (13) qui relève l'ensemble colonne (5) - pont (6) - pièce intermédiaire (7) jusqu'à ce que le second levier (11) soit arrêté par la came-butée (14).If the passage of a piece of wood on the return, or another accidental cause, tends to press on the bridge (6), it will come to press on the table (2) of the jointer, the column (5) descending relative to its guide (4) by compressing the return spring (13). Then the bridge (6) returns to its initial position under the thrust of this spring (13) which raises the column (5) - bridge (6) - intermediate piece (7) assembly until the second lever (11) either stopped by the cam-stop (14).

La figure 1 montre cette came-butée (14) arrêtée dans une position angulaire permettant un réglage du pont protecteur (6) en position basse. Au contraire, la figure 2 montre la même came-butée (14) arrêtée dans une position.angulaire permettant un réglage du pont (6) en position haute. Un système à friction, disposé entre le support (1) et la came-butée (14), maintient ladite came-butée dans la position angulaire choisie. Par manoeuvre du levier (16), l'opérateur peut évidemment obtenir toute position intermédiaire souhaitée pour le pont (6).Figure 1 shows this stop cam (14) stopped in an angular position allowing adjustment of the protective bridge (6) in the low position. On the contrary, Figure 2 shows the same stop cam (14) stopped in an angular position allowing adjustment of the bridge (6) in the high position. A friction system, disposed between the support (1) and the stop cam (14), maintains said stop cam in the angular position chosen. By operating the lever (16), the operator can obviously obtain any desired intermediate position for the bridge (6).

Dans la forme de réalisation décrite jusqu'ici en référence aux figures 1 et 2, le premier levier (8) est articulé par l'axe (9) à la pièce intermédiaire (7) qui sert à maintenir le pont protecteur (6), et l'axe d'articulation fixe (12) liant le second levier (11) au support (1) est situé au-dessous de l'axe (9),- à proximité de la colonne (5). Diverses variantes peuvent concerner la position de l'axe d'articulation (9) du premier levier (8) sur l'ensemble colonne (5) - pont (6) - pièce intermédiaire (7) et la position de l'axe d'articulation fixe (12) du second levier (11), ainsi que l'angle formé par les deux leviers (8,11), comme l'illustrent les figures 3 à 6 :In the embodiment described so far with reference to FIGS. 1 and 2, the first lever (8) is articulated by the axis (9) to the intermediate piece (7) which serves to maintain the protective bridge (6), and the fixed articulation axis (12) connecting the second lever (11) to the support (1) is located below the axis (9), - near the column (5). Various variants may relate to the position of the articulation axis (9) of the first lever (8) on the column (5) - bridge (6) - intermediate piece (7) assembly and the position of the axis of fixed articulation (12) of the second lever (11), as well as the angle formed by the two levers (8,11), as illustrated in FIGS. 3 to 6:

La figure 3 montre une forme de réalisation dans laquelle le second levier (8) a son axe fixe (12) d'articulation au support (1) situé en un point relativement éloigné de la colonne (5). La variante de la figure 4 comporte la même particularité en ce qui concerne l'axe fixe (12), mais l'angle formé par les deux leviers (8, 11) se trouve inversé.Figure 3 shows an embodiment in which the second lever (8) has its fixed axis (12) of articulation to the support (1) located at a point relatively distant from the column (5). The variant of Figure 4 has the same feature with regard to the fixed axis (12), but the angle formed by the two levers (8, 11) is reversed.

Dans la forme de réalisation selon la figure 5, le premier levier (8) est articulé par l'axe (9) à l'extrémité inférieure de la colonne (5) qui dépasse sous la partie guide (4) du support (1). L'axe d'articulation (12) liant le second levier (11) au support (1) est ici situé au-dessus de l'axe précité (9), à proximité de la colonne (5).In the embodiment according to FIG. 5, the first lever (8) is articulated by the axis (9) at the lower end of the column (5) which projects under the guide part (4) of the support (1) . The articulation axis (12) connecting the second lever (11) to the support (1) is here located above the aforementioned axis (9), near the column (5).

Dans une variante, l'axe d'articulation fixe (12) peut être situé en un point relativement éloigné de la colonne (5), comme l'illustre la figure 6.In a variant, the fixed articulation axis (12) can be located at a point relatively distant from the column (5), as illustrated in FIG. 6.

Dans la forme de réalisation de la figure 7, le levier (8) articulé par l'axe (9) à l'ensemble colonne (5) - pont (6) - pièce intermédiaire (7) et le levier (11) . articulé par l'axe (12) au support (1) sont toujours articulés entre eux par un axe (10), mais ils sont en outre liés l'un à l'autre par deux autres leviers articulés (17,18) qui forment avec les premiers leviers (8, 11) un parallélogramme déformable.In the embodiment of FIG. 7, the lever (8) articulated by the axis (9) to the column (5) - bridge (6) - intermediate piece (7) and the lever (11) assembly. articulated by the axis (12) to the support (1) are always articulated to each other by an axis (10), but they are also linked to each other by two other articulated levers (17,18) which form with the first levers (8, 11) a deformable parallelogram.

Enfin, dans la forme de réalisation de la figure 8, le levier (8) articulé par l'axe (9) à l'ensemble colonne (5) - pont (6) - pièce intermédiaire (7) n'est pas directement articulé au levier (11) articulé par l'axe (12) au support (1). Ces leviers (8,11) sont liés l'un à l'autre au moyen de deux autres leviers articulés (19, 20) qui forment avec les premiers un parallélogramme déformable.Finally, in the embodiment of FIG. 8, the lever (8) articulated by the axis (9) to the column (5) - bridge (6) - intermediate piece (7) assembly is not directly articulated to the lever (11) articulated by the axis (12) to the support (1). These levers (8,11) are linked to each other by means of two other articulated levers (19, 20) which form with the first a deformable parallelogram.

Le fonctionnement des diverses variantes selon les figures 3 à 8 est identique à celui du dispositif décrit de façon détaillée avec référence aux figures 1 et 2.The operation of the various variants according to FIGS. 3 to 8 is identical to that of the device described in detail with reference to FIGS. 1 and 2.

Il va de soi, et il résulte de ce qui précède, que l'invention ne se limite pas aux seules formes de réalisation de ce dispositif de protection pour dégauchisseuse qui ont été décrites ci-dèssus, à titre d'exemples ; elle en embrasse, au contraire, toutes les variantes comportant des moyens équivalents.It goes without saying, and it follows from the foregoing, that the invention is not limited to the sole embodiments of this protection device for jointer which have been described above, by way of examples; on the contrary, it embraces all the variants comprising equivalent means.
