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.
- the disclosed winding arrangement has a hexagonal bar on which a cord which is connected to the lowermost panel is wound up.
- the hexagonal bar has six flattened areas extending over the entire hexagonal bar.
- 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 at least one flattened area is formed on the lateral surface, which extends at least partially in the axial direction along the drum, wherein the drum has a feed region which extends approximately over the entire circumference of the drum , for a string or the like, and the at least one flattened area ends in front of the feed area.
- 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. On this side is the diameter reduced the winding drum. 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.
- winding drum according to the invention is suitable for use in blinds, blinds, Roman blinds, pleated curtains, etc.
- the drum has a feeding area for a string or the like, and the at least one flattened area ends before the feeding area.
- This measure facilitates the transport of the wound string or the like away from the feed area.
- 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 runs 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 inclined to the axis of the winding drum, one end of the plane is wider than the other end of the plane in a cylindrical winding drum in the basic form. 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 is a perspective view of an embodiment of a winding drum 10 is shown.
- 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 smoothly passes through a bevel 15 back into the conical surface of the drum 10, which is especially in Fig. 1b is clarified, showing 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 is a first side view of a generally cylindrical winding drum 20 is shown.
- 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. 2b can be seen in the rotated by 90 ° side view that the flattened portion 21 extends 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 shown.

Description
Die Erfindung betrifft eine Wickeltrommel einer Aufwickelanordnung, die auf oder an einer Welle der Aufwickelanordnung anordenbar ist, wobei die Wickeltrommel eine Mantelfläche aufweist.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.
Um Behänge kontrolliert abzulassen und wieder nach oben zu ziehen, sind Aufwickelanordnungen bekannt, an denen eine Schnur befestigt ist, die mit ihrem anderen Ende am unteren Ende des Behangs befestigt ist. Beim Auf-und Abwickeln der Schnur ist darauf zu achten, dass die Schnur sich gleichmäßig aufwickelt, ohne Schlaufen zu bilden. Insbesondere sind an einem Behang in der Regel zwei oder mehr Schnüre angeordnet, sodass auch mehrere Aufwickelanordnungen vorgesehen sind. Die Aufwickelanordnungen sollen die Schnüre gleichmäßig auf- und abwickeln, sodass es zu keiner Schräglage des Behangs kommt. Die Aufwickelanordnungen umfassen in der Regel eine Wickeltrommel, die zylindrisch oder kegelstumpfförmig ausgebildet ist.To drape hangings in a controlled manner and pull back up, Aufwickelanordnungen are known to which a cord is attached, which is attached at its other end to the lower end of the curtain. When winding and unwinding the line, make sure that the line winds evenly without forming loops. In particular, two or more cords are usually arranged on a curtain, so that several Aufwickelanordnungen are provided. The Aufwickelanordnungen should evenly unwind and unwind the strings, so there is no tilt of the curtain. The take-up assemblies typically include a winding drum that is cylindrical or frusto-conical in shape.
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Wickeltrommel weiterzubilden, sodass ein gleichmäßiges, kontrolliertes Auf- und Abwickeln einer Schnur oder dergleichen auf der Wickeltrommel ermöglicht wird.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.
Gelöst wird diese Aufgabe durch eine Wickeltrommel der eingangs genannten Art, wobei an der Mantelfläche wenigstens ein abgeflachter Bereich ausgebildet ist, der sich zumindest abschnittsweise in axialer Richtung entlang der Trommel erstreckt, wobei die Trommel einen Zuführbereich, der über den gesamten Umfang der Trommel rund verläuft, für eine Schnur oder dergleichen aufweist und der wenigstens eine abgeflachte Bereich vor dem Zuführbereich endet. Eine Wickeltrommel weist in der Regel einen runden Querschnitt auf. Wenn nun zumindest ein Bereich abgeflacht ist, ist der Querschnitt in einem Abschnitt nicht mehr vollständig rund. An dieser Seite ist der Durchmesser der Wickeltrommel reduziert. Dies bewirkt, dass eine auf die Wickeltrommel aufzuwickelnde Schnur besonders gut in axialer Richtung entlang der Wickeltrommel verschoben werden kann. Dadurch können bereits vorhandene Wicklungen durch neu hinzukommende Wicklungen verdrängt werden, ohne dass sich mehrere Wicklungen auf der Wickeltrommel übereinander legen und ohne dass übermäßige Reibung entsteht. Durch diese Maßnahme wird ein gleichmäßiges Auf- und Abwickeln sichergestellt. Die erfindungsgemäße Wickeltrommel ist für die Verwendung bei Rollos, Jalousien, Raffrollos, Plissee-Vorhängen etc. geeignet.This object is achieved by a winding drum of the aforementioned type, wherein at least one flattened area is formed on the lateral surface, which extends at least partially in the axial direction along the drum, wherein the drum has a feed region which extends approximately over the entire circumference of the drum , for a string or the like, and the at least one flattened area ends in front of the feed area. 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. On this side is the diameter reduced the winding drum. 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 blinds, blinds, Roman blinds, pleated curtains, etc.
Die Trommel weist einen Zuführbereich für eine Schnur oder dergleichen auf und der wenigstens eine abgeflachte Bereich endet vor dem Zuführbereich. Diese Maßnahme erleichtert den Transport der aufzuwickelnden Schnur oder dergleichen weg vom Zuführbereich. Insbesondere erfolgt eine Außenquerschnittsverringerung in einem Abschnitt der Wickeltrommel. Dadurch wird eine ähnliche Wirkung erzielt wie bei einer kegelstumpfförmigen Wickeltrommel, bei der der axiale Schnurtransport auf der Mantelfläche ausschließlich durch die Konizität der Wickeltrommel erleichtert wird. Im Bereich der Schnurzuführung verläuft die Trommel über ihren gesamten Umfang rund, damit sich die Schnur nicht in einem Spalt zwischen einem Lagerteil und der Trommel verklemmen und dadurch eine erhöhte Reibung erzeugen kann. Im Zuführbereich muss die Trommel rund sein, sodass durch die abgeflachten Bereiche quasi ein Durchmessersprung erzielt wird.The drum has a feeding area for a string or the like, and the at least one flattened area ends before the feeding area. This measure facilitates the transport of the wound string or the like away from the feed area. In particular, an outer cross-section reduction takes place in a section of the winding drum. As a result, 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. In the area of the line feed, the drum runs 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. In the feed area, the drum must be round so that the flattened areas result in a jump in diameter.
Die Wicklungen können auf besonders einfache Art und Weise auf den Bereich mit verringertem Außendurchmesser gelangen, wenn zwischen dem Zuführbereich und dem abgeflachten Bereich ein fließender Übergang, insbesondere eine Schräge, vorgesehen ist.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.
Bei einer alternativen Ausführungsform kann der Übergang vom Zuführbereich zum abgeflachten Bereich stufenförmig ausgestaltet sein. Dadurch wird es sicher vermieden, dass sich eine Wicklung unbeabsichtigt wieder in den Zuführbereich bewegt.In an alternative embodiment, 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.
Wenn der abgeflachte Bereich als Ebene ausgebildet ist, die schräg zur Achse der Wickeltrommel ausgelegt ist, ist bei einer in der Grundform zylindrischen Wickeltrommel ein Ende der Ebene breiter als das andere Ende der Ebene. Besonders bevorzugt ist es, wenn der abgeflachte Bereich sich zum Zuführbereich hin verschmälert. Dies bedeutet, dass sich die Ebene vom Zuführbereich weg in Richtung zur Achse der Trommel erstreckt. Auch bei einer Trommel mit einer zylindrischen Grundform kann auf diese Weise eine kontinuierliche Durchmesserverringerung erzeugt werden, die den axialen Schnurtransport erleichtert. Eine Ebene als abgeflachter Bereich, die an ihren gegenüberliegenden Enden unterschiedlich breit ist, kann auch bei in der Grundform kegelförmigen Wickeltrommeln vorgesehen sein. Durch unterschiedlich tiefe Ausnehmungen in der Trommel an den Enden der Ebene kann die Steigung der Ebene eingestellt werden.If the flattened portion is formed as a plane which is inclined to the axis of the winding drum, one end of the plane is wider than the other end of the plane in a cylindrical winding drum in the basic form. 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.
Bei einer bevorzugten Ausgestaltung der Erfindung können mehrere abgeflachte Bereiche vorgesehen sein, wobei sich vorzugsweise jeweils zwei abgeflachte Bereiche gegenüberliegen. Insbesondere können am Mantel der Trommel an zwei sich gegenüberliegenden Längsseiten abgeflachte Bereiche vorgesehen sein. Eine solche Ausgestaltung der Trommel ist insbesondere dann vorteilhaft, wenn diese als Kunststoffspritzgießteil hergestellt wird. In den abgeflachten Bereichen kann dann die Trennlinie der Spritzgießform verlaufen. An dieser Trennlinie entstehen häufig Grate, die die Schnur in ihrer axialen Verschiebung behindern könnten. Durch Vorsehen der abgeflachten Bereiche ist das Entstehen solcher Grate jedoch unschädlich.In a preferred embodiment of the invention, a plurality of flattened regions may be provided, wherein in each case preferably two flattened regions are opposite each other. In particular, 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. In 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.
Es ist denkbar, die Wickeltrommel im Wesentlichen zylindrisch oder kegelstumpfförmig auszubilden. Wenn die Ebene geneigt ist, kann eine zylindrische Grundform ausreichend sein. Bei einer kegelstumpfförmigen Grundform kann die Ebene ebenfalls schräg zur Achse der kegelstumpfförmigen Form angeordnet sein und damit in etwa parallel zu einer Tangente bzw. Tangentialebene der Trommeloberfläche liegen.It is conceivable to form 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.
