Definitions

  • the invention relates to a sewing machine according to the preamble of Claim 1.
  • a spring serving as a low-mass coupling element is arranged in between the linear motor drive rod and the presser bar .
  • the linear motor is vertically above arranged the presser bar and the spring is designed as a coil spring. Due to the comparatively large dimensions of the linear motor in terms of its diameter and length, it might not be within, but only be arranged outside the housing head. This would however not only the handling of the sewing machine, but also its Affect appearance.
  • the linear motor is lateral Distance to the presser bar and the spring arranged as a distance leaf spring bridging between the drive and presser bar educated. With this construction it seems rather possible that To accommodate the linear motor inside the machine housing. Because with one such an arrangement of a leaf spring but apart from the vertically directed forces Large horizontal force components also occur, are the drive and the Presser bar and its bearing large tilting forces and one exposed to increased wear.
  • the invention is therefore based on the object, one with a linear motor To create operated presser device, which together with the Linear motor at least largely housed within the machine housing can be and works with little wear.
  • the task is performed by the characterizing features of claim 1 solved.
  • the linear motor By arranging an angle lever and the measure, the spring record in a holder, on the one hand with the angle lever and on the other hand, connected to the presser bar, the linear motor be accommodated at least partially within the housing arm, so that he does not affect the handling of the sewing machine and beyond is largely protected against damage.
  • connection between the drive rod and one arm of the Angle lever and the other arm of the angle lever and the spring holder can be formed according to claim 2 as an elongated hole-pin connection or be accomplished according to claim 3 by a handlebar.
  • a presser bar 4 is mounted, which is at its lower end a presser foot 5 carries.
  • the presser bar 4 and the presser foot 5 together form a presser device.
  • a holding piece 6 is clamped, that is part of a spring holder 7.
  • the spring holder 7 contains another holding piece 8 above the holding piece 6.
  • a helical compression spring 9 is added between the two Holding pieces 6, 8, a helical compression spring 9 is added.
  • the two Holding pieces 6, 8 are connected by a screw 10, wherein the spring 9 located between them is biased. That way the lower holding piece 6 under spring force in contact with the screw head 11 held.
  • the two holding pieces 6, 8 can be further Compress the spring 9 to move towards each other.
  • the upper end of the upper holding piece 8 is by means of an elongated hole pin connection 12 articulated with a first arm 13 of an angle lever 14 connected.
  • the angle lever 14 is pivotable on a bearing plate 15 stored, which in turn on a comparatively much larger carrier plate 16 is screwed on.
  • a second arm 17 of the angle lever 14 is via a further slot-pin connection 18 with the drive rod 19 one with its longitudinal axis horizontally extending linear motor 20 articulated.
  • the linear motor 20 corresponds in structure and function to that in the beginning mentioned DE 199 45 443 A1 linear motor shown in Fig. 5.
  • the linear motor 20 is fastened to the carrier plate 16 with the aid of a holder 21.
  • the linear motor 20 extends together with its drive rod 19 within a recess 22 of the carrier plate 16.
  • the carrier plate 16 with the linear motor 20, the angle lever 14 and the upper holding piece 8 form a preassembled installation unit 23.
  • Das Installation unit 23 is mounted on the sewing machine in such a way that the support plate 16 is screwed onto the outside of the arm 2.
  • the spring 9 is between the two holding pieces 6, 8 inserted. After that, the two holding pieces 6, 8 connected with the help of the screw 10, wherein - how already mentioned - the spring 9 is biased. Now the drive rod is 19 of the linear motor 20 with the presser bar 4 in terms of drive connected.
  • the bias of the spring 9 can be set to a predetermined value adjust, if the screw 10 not against a stop, but only as far as screwed in to achieve the desired spring preload becomes. In this case, the screw-in position of the screw 10 can be done with the help secure a cross-set screw, not shown.
