Description

DISPOSITIF PRESSE-ETOFFE DANS UNE MACHINE A COUDRE PRESS-FABRICATION DEVICE IN A SEWING MACHINE
Dans les machines à coudre, il est connu de prévoir un dispositif presse-étoffe comprenant un support muni de moyens pour la retenue et la libération d'un pied presse-étoffe.In sewing machines, it is known to provide a stuffing device comprising a support provided with means for retaining and releasing a stuffing foot.
Il est aussi connu de prévoir différents accessoires de couture pouvant être utilisés avec une machine à coudre, accessoires qui sont souvent fixés à la barre presse-étoffe.It is also known to provide various sewing accessories which can be used with a sewing machine, accessories which are often attached to the press bar.
L'invention a pour but de faciliter la mise en place et l'enlèvement de ces accessoires. Ce but est atteint grâce au fait que le support de la barre presse-étoffe présente au moins une rainure formant glissière de guidage pour un accessoire de couture.The invention aims to facilitate the installation and removal of these accessories. This object is achieved thanks to the fact that the support of the stuffing bar has at least one groove forming a guide rail for a sewing accessory.
Le dessin annexé montre schématiquement et à titre d'exemple une forme d'exécution de l'objet' de l'invention.The accompanying drawing shows schematically and by way of example an embodiment of the object ' of the invention.
La figure 1 est une vue en perspective de la partie inférieure d'une barre presse-étoffe et montre divers accessoires de couture pouvant être fixés à cette barre.Figure 1 is a perspective view of the bottom of a press bar and shows various sewing accessories which can be attached to this bar.
La figure 2 est une coupe du support solidaire de l'extrémité infé¬ rieure de la barre presse-étoffe prise dans la direction de déplacement du tissu.Figure 2 is a section of the support integral with the lower end of the stuffing bar taken in the direction of movement of the fabric.
La figure 3 est une vue de la face supérieure de ce support.Figure 3 is a view of the upper face of this support.
La figure •-> es: une vue de ace de ce supoor:. La figure 1 représente en perspective une partie d'une barre presse- étoffe 1 dont l'extrémité inférieure est munie d'un support 2. Ce support présente une encoche 3 permettant la fixation d'un pied presse-étoffe k qui est muni d'une barrette transversale 5. Comme on le voit à la figure 2, le pied presse-étoffe est retenu dans l'encoche 3 au moyens d'une lame coulis¬ sante 6 qui peut être rétractée pour libérer le pied en agissant sur un levier de commande 7 présentant une plaque de fixation 8 auquel il est relié par une lame souple 9. La lame 6 présente une tête 10 reliée à une partie du levier 7. Une pression exercée sur ce levier 7 exerce un retrai t de la lame 6 pour dégager l'encoche 3 grâce à une flexion du bras 9. Comme le montrent les figures I et , le support 2 présente 2 rainures parallèles 1 1 et 12 ménagées sur deux faces latérales opposées du support. Ces rainures permettent de fixer sur le support divers accessoires de couture présentant une portion munie de languettes 13 et \ k venant s'engager dans lesdites rainures. Deux exemples de la forme de ces portions sont indiqués en 15 et 16 de la figure 1.Figure • -> es: an ace view of this supoor :. Figure 1 shows in perspective part of a press bar 1 whose lower end is provided with a support 2. This support has a notch 3 allowing the fixing of a press foot k which is provided with 'a transverse bar 5. As seen in Figure 2, the presser foot is retained in the notch 3 by means of a coulis¬ health blade 6 which can be retracted to release the foot by acting on a lever control 7 having a fixing plate 8 to which it is connected by a flexible blade 9. The blade 6 has a head 10 connected to a part of the lever 7. A pressure exerted on this lever 7 exerts a withdrawal of the blade 6 for release the notch 3 by bending the arm 9. As shown in Figures I and, the support 2 has 2 parallel grooves 1 1 and 12 formed on two opposite side faces of the support. These grooves make it possible to fix on the support various sewing accessories having a portion provided with tabs 13 and \ k coming to engage in said grooves. Two examples of the shape of these portions are indicated in 15 and 16 of FIG. 1.
Le support 2 présente encore un perçage 17 permettant la fixation d'accessoires muni d'une tige tel le que 1 8 ou 19 venant s'engager dans le perçage 17, qui est orthogonal à l 'axe de la barre 1.The support 2 also has a bore 17 allowing the attachment of accessories provided with a rod such as 1 8 or 19 coming to engage in the bore 17, which is orthogonal to the axis of the bar 1.
Le support 2 est muni d'un disposi tif coupe-fil 20. par exemple du genre de celui décrit dans le brevet suisse N'° 635.803.The support 2 is provided with a wire cutter 20, for example of the type described in Swiss patent N ° 635.803.
Dans le cas de la portion 15, qui présente une échancrure 21 venant s'engager sur la base de la barre I , il est prévu une tige de verrouillage 22 destinée à s'engager dans une ouverture 23 prévue sur la base supérieure du support 2 pour constituer un cran pour maintenir en place l 'accessoi re combiné avec la portion 15.In the case of the portion 15, which has a notch 21 coming to engage on the base of the bar I, there is provided a locking rod 22 intended to engage in an opening 23 provided on the upper base of the support 2 to form a notch to hold in place the accessory combined with the portion 15.
Le support présente encore sur ses faces avant et arrière deux rainures 7k et 25, de sorte qu'il est possible de fixer simultanément sur le support 2 des accessoires de couture différents, par exemple ur, Died part . - cul ier. notamment un pied pour le reprisage et un écran protecteur transparent destiné à éviter que l'usager puisse introduire ses doigts dans la zone de aι : de l 'aiguille. La face avant du support 2 est munie d 'une fenêtre 26 translucide derrière laquelle se trouve une ampoule électrique 27 (figure 2) montée dans la partie inférieure de la barre 1, qui facilite l'opération d'introduction du fil dans le chas de l'aiguille.The support also has on its front and rear faces two grooves 7k and 25, so that it is possible to fix simultaneously on the support 2 different sewing accessories, for example ur, Died part. - cul ier. in particular a darning foot and a transparent protective screen intended to prevent the user from being able to introduce his fingers into the aι: needle. The front face of the support 2 is provided with a translucent window 26 behind which there is an electric bulb 27 (FIG. 2) mounted in the lower part of the bar 1, which facilitates the operation of introducing the wire into the eye of the needle.
En vue d'obtenir une commande automatique du mode de fonction¬ nement de la machine, il est possible de prévoir un ou plusieurs contacts électriques sur le support 1 , ces contacts étant destinés à être rendus actifs par la mise en place d'un accessoire déterminé sur le support. Ces contacts pourraient être placés dans une ou plusieurs des rainures 1 1 , 12, 2k et 25. ou encore à l 'intérieur de l 'alésage 17 ou au dessous de l 'ouverture 23. Il est évident que ces contacts devraient être reliés à au moins un conducteur isolé passant dans la barre i . cette dernière présentant une portion conduc¬ trice séparée coopérant avec une prise de contact faisant partie de la machine à coudre. Ainsi, lorsqu'on utilise un accessoire de couture demandant une vitesse plus basse ou au contraire plus élevée que la gamme de vitesse habi¬ tuelle, la fermeture d'un contact correspondant pourrait être utilisé pour commander le changement de vitesse approprié. Ce ou ces contacts pourraient aussi être prévus pour alimenter au moins un moteur ou un dispositif faisant partie d'un accessoire. A titre d'exemple, on peut prévoir un moteur électrique pour actionner un accessoire coupe-tissu, ou même deux moteurs pour com¬ mander des déplacements prédéterminés d'un ouvrage de broderie.In order to obtain an automatic control of the operating mode of the machine, it is possible to provide one or more electrical contacts on the support 1, these contacts being intended to be made active by the fitting of an accessory. determined on the support. These contacts could be placed in one or more of the grooves 1 1, 12, 2k and 25. Or else inside the bore 17 or below the opening 23. It is obvious that these contacts should be connected to at least one insulated conductor passing through the bar i. the latter having a separate conductive portion cooperating with a contact making part of the sewing machine. Thus, when using a sewing accessory requiring a lower speed or on the contrary higher than the usual speed range, the closing of a corresponding contact could be used to control the appropriate change of speed. This or these contacts could also be provided to supply at least one motor or a device forming part of an accessory. By way of example, an electric motor can be provided to actuate a fabric cutter accessory, or even two motors to control the predetermined movements of an embroidery work.
Le support décrit permet de fixer à la barre presse-étoffe des acces¬ soires de couture tel qu'un pied à repriser , un pied fronceur, un piedboucie . un guide tissu universel, un guide monogame , etc.The support described makes it possible to fix sewing accessories such as a darning foot, a gathered foot, a soft foot to the presser bar. a universal fabric guide, a monogamous guide, etc.
Il est bien entendu que l'on pourrait prévoir di verses modif ications ou simplifications. Notamment, le support 2 pourrai t ne présenter qu 'une seule rainure, cel le-ci pouvant être par exemple en queue d'aronde et être munie d 'une vis de serrage pour bloquer la par tie introduite dans cette rainure . It is understood that provision could be made for various modifications or simplifications. In particular, the support 2 could only have one groove, this may for example be in dovetail and be provided with a clamping screw to block the part introduced in this groove.
