Definitions

  • the invention relates to a winding drum of a winding arrangement, which can be arranged on or on a shaft of the winding arrangement, wherein the winding drum has a lateral surface.
  • Object of the present invention is to develop a winding drum, so that a uniform, controlled winding and unwinding of a string or the like. On the winding drum is made possible.
  • a winding drum of the aforementioned type wherein on the lateral surface at least a flattened area is formed, which extends at least partially in the axial direction along the drum.
  • a winding drum usually has a round cross-section. Now, if at least one area is flattened, the cross-section in a section is no longer completely round. At this point, the diameter of the winding drum is reduced. This has the effect that a cord to be wound onto the winding drum can be displaced particularly well in the axial direction along the winding drum. As a result, already existing windings can be displaced by newly added windings without several windings overlapping one another on the winding drum and without excessive friction occurring. This measure ensures uniform winding and unwinding.
  • the winding drum according to the invention is suitable for use in roller blinds, blinds, Roman blinds, Plisee curtains, etc.
  • the drum has a feed area for a string or the like and ends the at least one flattened area in front of the feed area.
  • This measure facilitates the transport of the cord to be wound or the like away from the feed.
  • an outer cross-section reduction takes place in a section of the winding drum.
  • a similar effect is achieved as in a frustoconical winding drum, in which the axial line transport on the lateral surface is facilitated solely by the conicity of the winding drum.
  • the drum In the area of the line feed, the drum can run around its entire circumference, so that the line can not jam in a gap between a bearing part and the drum and thereby generate increased friction.
  • the drum In the feed area, the drum must be round so that the flattened areas result in a jump in diameter.
  • the windings can reach the area of reduced outer diameter in a particularly simple manner if a flowing transition, in particular a bevel, is provided between the feed area and the flattened area.
  • the transition from the feed region to the flattened region can be designed in a stepped manner. This reliably prevents a winding from unintentionally moving back into the feed area.
  • the flattened portion is formed as a plane which is oriented obliquely to the axis of the winding drum, one end of the plane is broader in the case of a cylindrical winding drum in the basic form than the other end of the plane. It is particularly preferred if the flattened area narrows towards the feed area. This means that the plane extends away from the feed area in the direction of the axis of the drum. Even with a drum having a cylindrical basic shape, a continuous reduction in diameter can be produced in this way, which facilitates the axial transport of the string.
  • a plane as a flattened area attached to her opposite ends is different widths can also be provided in the basic shape conical winding drums. By different deep recesses in the drum at the ends of the plane, the slope of the plane can be adjusted.
  • a plurality of flattened regions may be provided, wherein in each case preferably two flattened regions are opposite each other.
  • flattened regions can be provided on the jacket of the drum on two opposite longitudinal sides.
  • Such a design of the drum is particularly advantageous if it is produced as a plastic injection molded part.
  • the flattened areas can then run the dividing line of the injection mold. At this parting line often arise burrs that could hinder the string in their axial displacement. By providing the flattened areas, however, the occurrence of such burrs is harmless.
  • the winding drum substantially cylindrical or frusto-conical. If the plane is inclined, a cylindrical basic shape may be sufficient. In a frusto-conical basic shape, the plane can also be arranged obliquely to the axis of the frusto-conical shape and thus lie approximately parallel to a tangent or tangential plane of the drum surface.
  • FIG. 1a an embodiment of a winding drum 10 is shown in a perspective view.
  • This drum 10 is designed round, wherein it tapers conically from the end 12 to the end 11.
  • On its longitudinal sides, it has flattened areas 14 which, however, do not extend over the entire length of the drum 10, but end before the actual line feed area 16.
  • the flattened region 14 merges smoothly again by a bevel 15 into the conical lateral surface of the drum 10, which is also illustrated in particular in FIG. 1b, which shows the drum 10 in longitudinal section through the flattened regions 14 and 14 '.
  • the regions 14 and 14 'with the transition regions 15 and 15' are arranged exactly opposite each other. In their area, the dividing line of an injection mold for producing the drum 10 can run.
  • a cover or a housing may be provided for the winding drum 10. To a single-layer winding To ensure a cover, which is spaced about cord thickness of the lateral surface of the feed region 16, in the supply region 16, that is only over a part of the length of the drum 10 may be sufficient.
  • FIG. 2a shows a first side view of a winding drum 20 that is cylindrical in its basic form.
  • a flattened area 21 can be seen, which widens from its left end 22 to its right end 23. This means that the flattened region 21 extends obliquely to the axis of the winding drum 20. The further one moves away from the feed region 24, the wider becomes the flattened region 21.
  • FIG. 2 b it can be seen in the side view rotated by 90 ° that the flattened region 21 runs obliquely to the axis 25 of the drum 20.
  • the transition region is formed as a slope 26.
  • Fig. 3 is a sectional view through the winding drum 20 of Fig. 2a is shown.
  • the lateral surface 27 of a cylindrical basic shape can be seen.
  • the flattened portions 21 ', 21 " are the flattened portions 21 ".
