Description

La plupart des machines à coudre connues comprennent dans leur partie inférieure un mécanisme de prise de boucle placé sous un couvercle formé par une plaque et permettant l'accès à ce mécanisme, ce couvercle étant engagé dans un logement d'une plaque de base formant une partie de la surface de travail.Most known sewing machines include in their lower part a loop-taking mechanism placed under a cover formed by a plate and allowing access to this mechanism, this cover being engaged in a housing of a base plate forming a part of the work surface.

L'invention a pur but de faciliter pour l'usager la manoeuvre d'ouverture et de fermeture de ce couvercle.The object of the invention is to make it easier for the user to open and close this cover.

A cet effet, la machine à coudre selon l'invention est caractérisée en ce que le couvercle est relié à la plaque de base par un dispositif à pivot dont l'axe de pivotement est sensiblement perpendiculaire à la plaque du couvercle et passe à proximité d'une portion de la périphérie du couvercle, ce dispositif permettant un coulissement suivant son axe de pivotement, un organe de rappel élastique sollicitant le couvercle vers l'intérieur du logement, un organe de commande manuelle permettant de déplacer le couvercle contre l'action de l'organe de rappel pour extraire le couvercle de son logement.For this purpose, the sewing machine according to the invention is characterized in that the cover is connected to the base plate by a pivot device whose pivot axis is substantially perpendicular to the cover plate and passes close to it. '' a portion of the periphery of the cover, this device allowing sliding along its pivot axis, an elastic return member urging the cover towards the interior of the housing, a manual control member making it possible to move the cover against the action of the return member for extracting the cover from its housing.

La machine représentée à la figure 1 est constituée de façon classique par un socle 1 supportant un bras inférieur 2 et une colonne 3 portant un bras supérieur 4, à l'extrémité duquel se trouve la barre porte-aiguilles 5.The machine shown in FIG. 1 is conventionally constituted by a base 1 supporting a lower arm 2 and a column 3 carrying an upper arm 4, at the end of which is the needle holder bar 5.

Comme le montre la figure 2, la face supérieure du bras libre 2 porte une plaquette 6 recouvrant le mécanisme du transporteur dont les griffes 7 sont visibles, tandis qu'un couvercle 8 muni d'une fenêtre transparente 9 recouvre le mécanisme de prise de boucle, qui n'est pas représenté. L'ouverture de ce couvercle 8 est commandée par une simple pression sur un bouton de commande 10.As shown in FIG. 2, the upper face of the free arm 2 carries a plate 6 covering the conveyor mechanism, the claws 7 of which are visible, while a cover 8 provided with a transparent window 9 covers the loop-taking mechanism , which is not shown. The opening of this cover 8 is controlled by a simple pressure on a control button 10.

Comme on le voit à la figure 3, le couvercle 8 est constitué par une plaque qui est engagée dans un logement 11 prévu dans une plaque de base 12. Le couvercle 8 est relié à la plaque de base 12 par un dispositif à pivot dont l'axe de pivotement est sensiblement perpendiculaire à la plaque du couvercle et passe à proximité d'une portion de la périphérie de ce dernier. Ce dispositif permet un coulissement du couvercle suivant son axe de pivotement. A cet effet, un pivot 13 est solidaire du couvercle 8 et passe dans deux alésages ou paliers 14 et 15 prévus dans la plaque de base 12 et respectivement dans une pièce 16 en forme d'équerre qui est solidaire de cette plaque 12. Le pivot 13 peut ainsi tourner et coulisser dans les alésages 14 et 15.As seen in Figure 3, the cover 8 consists of a plate which is engaged in a housing 11 provided in a base plate 12. The cover 8 is connected to the base plate 12 by a pivot device whose the pivot axis is substantially perpendicular to the cover plate and passes close to a portion of the periphery of the latter. This device allows the cover to slide along its pivot axis. For this purpose, a pivot 13 is integral with the cover 8 and passes through two bores or bearings 14 and 15 provided in the base plate 12 and respectively in a part 16 in the form of a square which is integral with this plate 12. The pivot 13 can thus turn and slide in the bores 14 and 15.

Le pivot 13 est soumis à l'action d'un ressort à boudin 17 qui agit simultanément en compression et en torsion. Les spires de son extrémité inférieure ont un diamètre plus petit que celui du pivot, de façon à enserrer ce dernier pour en être rendu solidaire par friction. La partie supérieure du ressort présente des spires espacées entre elles et dont le diamètre intérieur est plus grand que celui du pivot. L'extrémité supérieure du ressort prend appui contre la plaque de base 12 pour exercer sur le pivot une poussée axiale dirigée vers le bas et contre la pièce 16 en équerre pour exercer sur le pivot une torsion tendant à ouvrir le couvercle 8 dans le sens de la flèche f de la figure 2.The pivot 13 is subjected to the action of a coil spring 17 which acts simultaneously in compression and in torsion. The turns of its lower end have a smaller diameter than that of the pivot, so as to enclose the latter to be made integral by friction. The upper part of the spring has spiers spaced apart and whose inner diameter is larger than that of the pivot. The upper end of the spring bears against the base plate 12 to exert an axial downward thrust on the pivot and against the piece 16 at right angles to exert a twist on the pivot tending to open the cover 8 in the direction of arrow f in Figure 2.

Pour ouvrir le couvercle 8 il faut le dégager du logement 11 de la plaque 12, ce qui est réalisé à l'aide d'un levier 18 articulé par un pivot 19 sur la plaque 12 et dont une extrémité constitue le bouton 10, son autre extrémité étant formée par un bec 20 prenant appui contre la face inférieure du couvercle 8, à proximité immédiate du pivot 13. Une pression exercée sur le bouton 10 fait basculer le levier 18 et soulève le couvercle 8 contre l'action du ressort 17. Dès que le couvercle est dégagé de son logement, la torsion exercée par le ressort 17 sur le pivot fait tourner le couvercle pour ouvrir l'accès à la canette.To open the cover 8 it must be released from the housing 11 of the plate 12, which is achieved using a lever 18 articulated by a pivot 19 on the plate 12 and one end of which constitutes the button 10, its other end being formed by a spout 20 bearing against the underside of the cover 8, in the immediate vicinity of the pivot 13. A pressure exerted on the button 10 switches the lever 18 and lifts the cover 8 against the action of the spring 17. As soon as the cover is released from its housing, the torsion exerted by the spring 17 on the pivot rotates the cover to open the access to the bobbin.

Comme montré à la figure 2, une butée 21 solidaire de la face inférieure 8 est destinée à coopérer avec un bord 22 du logement prévu dans la plaque 12 afin de déterminer l'angle d'ouverture du couvercle 8.As shown in FIG. 2, a stop 21 integral with the lower face 8 is intended to cooperate with an edge 22 of the housing provided in the plate 12 in order to determine the opening angle of the cover 8.

Un bossage 23 solidaire du couvercle ou du bord du logement sert à fixer la position de fermeture du couvercle de façon à obtenir le parallè- lisme entre les bords du couvercle et ceux du logement.A boss 23 integral with the cover or the edge of the housing serves to fix the closed position of the cover so as to obtain parallelism between the edges of the cover and those of the housing.

Les figures 4 et 5 illustrent une variante d'exécution qui permettent une plus grande facilité du réglage du couple exercé par le ressort 17.FIGS. 4 and 5 illustrate an alternative embodiment which makes it easier to adjust the torque exerted by the spring 17.

L'éxtrémité inférieure du pivot 13 est toujours engagée dans un palier de la pièce 16. Par contre la partie supérieure de ce pivot tourne et coulisse dans une pièce 24 en matière plastique, qui est vissée sur la pièce 16. Comme le montre la figure 4, le pivot 13 porte un téton 25 qui est engagé dans une encoche 26 de la pièce 24, en position de fermeture du couvercle 8.The lower end of the pivot 13 is always engaged in a bearing of the part 16. On the other hand, the upper part of this pivot turns and slides in a plastic part 24, which is screwed onto the part 16. As shown in the figure 4, the pivot 13 carries a stud 25 which is engaged in a notch 26 in the part 24, in the closed position of the cover 8.

Un mécanisme à rampe permet d'éviter que pendant le mouvement d'ouverture la face inférieure frotte contre le bord supérieur de la plaque 12. A cet effet la pièce 24 présente une rampe arquée 27 formée par une première portion 28 de faible inclinaison, puis d'une seconde portion 29 de plus forte inclinaison et en fin d'une portion 30. Lorsqu'on presse le bouton 10, le téton 25 est tout d'abord dégagé de son encoche 26 et à ce moment la face inférieure du couvercle 8 a été soulevée au-dessus du niveau de la face supérieure de la plaque 12. Sous l'effet du ressort de torsion, le téton 25 coopère avec la faible rampe 28, ce qui permet une accélération facile du mouvement de rotation du couvercle 8. Ensuite. le téton 25 doit franchir la rampe 29 pour arriver sur la portion 30, ce qui freine un peu le mouvement de rotation.A ramp mechanism makes it possible to prevent the lower face from rubbing against the upper edge of the plate during the opening movement. To this end, the part 24 has an arcuate ramp 27 formed by a first portion 28 of slight inclination, then a second portion 29 of greater inclination and at the end of a portion 30. When the button 10 is pressed, the stud 25 is first released from its notch 26 and at this time the underside of the cover 8 has been raised above the level of the upper face of the plate 12. Under the effect of the torsion spring, the stud 25 cooperates with the weak ramp 28, which allows easy acceleration of the rotation movement of the cover 8. Next. the stud 25 must cross the ramp 29 to reach the portion 30, which slightly slows down the rotational movement.

L'extrémité inférieure du ressort 17 est engagé dans une encoche d'une bague 31 présentant des créneaux 32 pour être retenus par une goupille 33 du pivot 13. L'extrémité supérieure 34 du ressort 17 est engagé dans une encoche 35 de la pièce 24. Cette disposition permet un réglage facile de la torsion initiale du ressort 17, ceci en soulevant la bague 31 pour la dégager du têton 33 et la laisser prendre position sur cette goupille par le créneau 32, qui correspond à la tension désirée.The lower end of the spring 17 is engaged in a notch of a ring 31 having slots 32 to be retained by a pin 33 of the pivot 13. The upper end 34 of the spring 17 is engaged in a notch 35 of the part 24 This arrangement allows easy adjustment of the initial torsion of the spring 17, this by lifting the ring 31 to disengage it from the pin 33 and let it take position on this pin by the slot 32, which corresponds to the desired tension.
