Definitions

  • the invention relates to a lighting device for a sewing machine according to the preamble of Claim 1.
  • a lighting device is known from US Pat. No. 4,413,310 become known in which a light bulb inside the Head to the side of the needle and presser foot bar in the Height is arranged adjustable. This light bulb is well able to work in the radiation area of the Illuminate lamp.
  • the disadvantage is that the needle and presser foot shadows arise and specifically in the puncture area of the needle.
  • DE-A1 3525698 is also one Known lighting device, which two rod-shaped Includes filament, the side of the needle bar or Presser foot bar are arranged. With this tandem arrangement you can already get a relatively good illumination reach the job.
  • the attachment of two Luminaires and their electrical supply are very needed a lot of space that is not available on a sewing machine. As a result, the luminaries come very close Job, i.e. to lie on the material support, and it there is a constant risk that the seamstress will slightest carelessness in contact with the hot Surface of the light bulbs arrives and burns suffers. Furthermore, working in the area of large radiant heat of the lamps is not very pleasant.
  • the object of the present invention is to create a Lighting device, on the one hand shadow-free illumination of the work, in particular of the needle insertion area and none Represents a danger to the seamstress.
  • a tubular, curved lamp which the needle and presser foot bar in at least one Angular range of 180 ° surrounds can be done on the smallest Mount the space below the head of the sewing machine and use Supply energy.
  • a cold light cathode fluorescent lamp (CFL lamp) gives a bright pleasant light and only almost does not cause one measurable heat radiation. This enables the lamp to attach very close to the machine housing and also the Lamp in an arc of up to approximately 360 ° around the needle and guide the presser foot bar around.
  • Can be used as reflectors those made of plastic with a reflective Coating can be used. Their manufacture and Assembly are very inexpensive.
  • Figure 1 shows the outline of a sewing machine 1 with a Forearm 3, the gripper system (not shown) records, the top of which forms the work surface 5.
  • the drives and Guided tours are not shown as they are from the state of the Technology are well known and their structure none Has influence on the lighting device.
  • the lower The area of the head 7 of the machine 1 is shown in FIGS. 1 and 2 shown cut away to show the details of the To make lighting device 17 visible. Latter can, if it is not embedded in the head 7, too be placed on top of this.
  • the lighting device 17 comprises at least one Lamp or a lamp 19, which the needle bar 9th and the presser foot rod 13 over an angular range of wraps at least 180 °, preferably approximately 360 °.
  • the lamp 19 is tubular and works preferably on the principle of cold light cathode fluorescence. Such lamps are known and under the Description CFL lamps on the market. You find so far Use in electronic devices as Backlight.
  • the lamp 19 is arranged on a lamp holder 21 which is also reflective above the lamp and Can have areas 23 whose position is adjustable.
  • the two ends 25 of the tubular lamp 19 are with Provide connectors that are perpendicular to Extension of the lamp 19 are arranged and the form electrical connection and at the same time the attachment can serve on the lamp holder 21.
  • the lamp 19 is consequently in a simple, tool-free manner Lamp holder 21 insertable.
  • the lamp holder 21 comprises corresponding plug receptacles (not shown), which are connected to a power source in the sewing machine 1.
  • the ends 25 of the lamp 19 can also be used Be provided connecting lines, which are known Means are connected to the power source.
  • the lamp 19 preferably has a contour of the head 7 shape adapted to the sewing machine 1; therefore it is mostly rectangular, the two ends 25 of the Lamp 19 are just as far apart that when Inserting or replacing the lamp 19 the distance is sufficient, so that the presser foot bar 13 and the needle bar 9 can be passed through.
  • the lamp 19 from two U-shaped or to assemble semicircular parts so that an im substantially continuous circular light output the needle 11 is done around.
  • the adjustable regions 23 can be attached to the lamp holder 21 be articulated to certain parts of the Illuminate work surface 5 more or less strongly.
  • the pivotable areas 23 are Lamp holder 21 by means of film or conventional Hinges connected.
  • FIGS. 5 to 8 A possible embodiment is shown in FIGS. 5 to 8 a hinge 25 shown with which the pivotable areas 23 and the fixed areas 21st are interconnected.
  • a hinge 25 shown with which the pivotable areas 23 and the fixed areas 21st are interconnected.
  • At the ends of the movable, pivotable areas 23 is a cylindrical shell Injection molded section 27, which one cylindrical jacket-shaped section 29, which on fixed area 21 is attached.
  • the two assembled cylindrical jacket-shaped parts 27 and 29 form a pivot bearing for the swiveling area 23.
  • Zum Adjustment of the pivotable area 23 can be done on this lobe-shaped or tab-shaped handle part 31 may be formed.
  • the entire lamp holder 21 can also be articulated be connected to the head 7 of the sewing machine 1 and by means of appropriate adjusting means, e.g. one Set screw, the position of the lamp 19 with respect to Work surface 5 can be adjusted or adjusted.
  • appropriate adjusting means e.g. one Set screw
