Definitions

  • the invention relates to a new construction making it possible to obtain such an axial unwinding of the wire in combination with a handle.
  • the handle according to the invention is characterized in that it has, at each of its ends, an arm which can be moved from a retracted position to a deployed position for use, one of these arms being arranged for carry a spool pin which is substantially parallel to the handle when this arm is in the deployed position, the other arm being provided with a thread guide situated substantially in the axis of the spool pin when the two arms are in their deployed position.
  • a sewing machine 1 of which only the upper part has been shown, is provided with a handle 2, articulated on pivots 3 cooperating with the frame of the machine so as to be able to assume a position deployed, shown in Figure 1, and respectively a retracted position, visible in Figure 2, which is mainly used for storage.
  • the handle comprises a middle part 4 which has at each of its ends a curved portion 5 carrying the pivot 3. These two pivots 3 are coaxial and parallel to the middle part of the handle.
  • the handle has housings 6 and 7 in which two arms 8 and 9 can be retracted, pivotally mounted along an axis parallel to the middle part 4.
  • the housings 6 and 7 have guide grooves 10 in which it is possible to slide the tongues 11 secured to a base 12 carrying a reel holder rod 13.
  • this reel holder rod 13 constitutes an accessory which is not used only when you want to sew with two threads.
  • the base 12 and the rod 13 are removed from the housing 6, so that the latter can receive the arm 8 to come into the retracted position shown in FIG. 4.
  • the arm 8 is provided a spool holder 14, on which a spool of wire 15 can be placed, shown in phantom.
  • a disc 16, pierced at its center, is engaged in friction on the rod 14 and serves, on the one hand, to axially retain the coil 15 and, on the other hand, to constitute a smooth bearing surface for the wire 17 that we unwind in the reel.
  • This wire 17 passes through a wire guide 18 forming part of the arm 9.
  • This arm 9 with the wire guide are shown in more detail in FIG. 5.
  • This arm 9 can advantageously be made of injected plastic and has a cylindrical hole 19 with a longitudinal slot 20 opening towards the outside of the arm and constituting the active part of the wire guide.
  • a spring hook 21 makes it possible to introduce the wire into the hole 19 by passing it parallel to itself in the slot 20 and then prevents the wire from escaping through this same slot.
  • the spring 21 is fixed to the arm 2 using a tubular rivet 22 which constitutes a second thread guide which can be used when carrying out a sewing job simultaneously using two threads.
  • the wire guide preferably has two hooks 21 disposed respectively on each side of the part 23 of the arm 9.
  • FIG. 5 also shows that the arm 9 has two pins, one of which only 24 is visible in the drawing, allowing the articulation of the arm 9 on the handle.
  • the arm 9 has a boss 25 on each of its sides, these bosses being intended to cooperate with recesses 26 (Fig. 3) to form notches elastically retaining the arm 9 in its deployed position and respectively retracted.
  • FIG. 6 shows a part 27 which serves to retain the pins 24 of the arm 9, as well as those of the arm 8 which is articulated on the handle in the same way as the arm 9.
  • This part 27 has a half bearing 28 for retaining the pins 24 which cooperate with another half bearing provided inside the housings 6 and 7 respectively.
  • This part 27 also has a passage 29 provided for fixing it to the handle by means of a screw. This arrangement is advantageous, because it easily makes it possible to disassemble an arm to replace it with a new one in the event that the user has damaged or broken it.
  • FIG. 7 represents the arm 8 which is provided with the reel-carrying rod 14 and which is constituted in the same way as the arm 9, that is to say that it comprises two pins 24 and a boss 25 for fixing its positions deployed and respectively retracted.
  • the middle part 4 of the handle has a recess 30 in which the rod 14 is housed, when the arm 8 is in the retracted position, as illustrated in FIG. 4.
  • the handle 2 does not necessarily have to be articulated to the machine 1 and that it could be rigidly secured to the latter.
  • the arms 8 and 9 could also be pivoted on the handle along axes which are not parallel to part 4 of the handle, these axes possibly being, for example, vertical.
  • the arms 8 and 9 do not necessarily have to be articulated on the handle and they could very well be placed on the latter by mutual engagement of recessed and raised parts, with possible retaining means by elastic catch or snap-fastening.
