Description

Wäscheschirm Rotary Dryer
Die Erfindung betrifft einen Wäscheschirm mit einem Mast und mit einem entlang des Mastes verschiebbaren Gleitgelenk an dem die Wäscheleine tragende Arme schwenkbar gelagert sind, wobei Spreizarme vorgesehen sind, welche jeweils einerseits gelenkig mit dem Mast und andererseits gelenkig mit den Armen verbunden sind,The invention relates to a laundry screen with a mast and with a slidable along the mast sliding joint on the clothesline supporting arms are pivotally mounted, wherein spreading arms are provided, which are each hinged on the one hand articulated to the mast and on the other hand hinged to the arms,
Bei bekannten Wäscheschirmen dieser Art (z.B. US-PS 2 289 450) erfordert das Aufspannen des Wäscheschirms in der Anfangsphase einen verhältnismäßig hohen Kraftaufwand, bis die Arme eine gewisse Winkellage erreicht haben. Man hat bereits versucht, durch Verwendung einer flaschenzugartig geführten Aufzugsleine diesen Missstand zu verbessern. Aber auch einer derartige Einrichtung kann das Aufspannen des Wäscheschirms erst dann erleichtern, wenn die Arme um einen gewissen Winkelbetrag aus ihrer senkrechten Ruhelage heraus verschwenkt sind, was von Hand erfolgen muss.In known laundry umbrellas of this type (e.g., U.S. Patent No. 2,289,450), the tensioning of the laundry screen in the initial phase requires a relatively high amount of force until the arms have reached a certain angular position. Attempts have already been made to improve this malady by using a pulley-like elevator cord. But even such a device can only facilitate the clamping of the laundry screen when the arms are pivoted by a certain angle from its vertical rest position out, which must be done by hand.
Durch die EP 0 649 935 B1 wurde ein Wäscheschirm mit einer Aufspreizeinrichtung bekannt, bei der an dem Mast unterhalb der Halteachsen längs verschiebbar ein Spreizkörper angebracht ist, der mit an den Spreizarmen angebrachten Stützelementen zusammenwirkt und bei einer Längsverschiebung die Spreizarme aus ihrer eingeklappten Ruhelage herausschwenkt. Dabei ist es erforderlich, eine umfangreiche Mechanik im Mast anzuordnen, die über das Zugseil beaufschlagt wird. Zudem sind Durchbrüche im Mast erforderlich, in die die Stützelemente eingreifen. Der Bauaufwand ist erheblich.EP 0 649 935 B1 discloses a laundry screen with a spreading device in which a spreader body is mounted longitudinally displaceably on the mast below the holding axes, which cooperates with supporting elements attached to the spreader arms and pivots the spreader arms out of their retracted rest position during a longitudinal displacement. It is necessary to arrange an extensive mechanism in the mast, which is acted upon by the pull rope. In addition, openings in the mast are required, in which engage the support elements. The construction cost is significant.
Weiter ist durch die EP 0 898 006 A2 ein Wäscheschirm mit einer Aufspreizeinrichtung bekannt, bei dem die Aufspreizvorrichtung eine dem Haltestern benachbarte, erste Hülse besitzt, die durch stabförmige Spreizorgane mit einer vom Gleitgelenk entfernten, zweiten Hülse verbunden ist, die durch Ziehen am Zugseil zum Auslenken der Spreizorgane zur ersten Hülse hin verschiebbar ist. Auch bei dieser Ausführungsform sind bewegliche, separat zu montierende Teile erforderlich, die den Fertigungsprozess verteuern und zu Störungen, bedingt unter anderem aus Witterungseinflüssen, führen können.Furthermore, EP 0 898 006 A2 discloses a laundry screen with a spreading device, in which the spreading device forms a washing screen Holding star adjacent, first sleeve has, which is connected by rod-like spreading organs with a remote from the sliding joint, the second sleeve, which is displaceable by pulling the pull cable for deflecting the spreading members to the first sleeve. Also in this embodiment, movable parts to be mounted separately are required, which make the manufacturing process more expensive and can lead to disruptions, inter alia, due to the effects of weathering.
Eine wesentliche Verbesserung in dieser Hinsicht wird bei dem Wäscheschirm gemäß der EP-B1-0 113 789 dadurch erreicht, dass bei eingeklappten Wäscheschirm die Anlenkachsen der Spreizarme an den Armen deutlich außerhalb der gedachten Verbindungslinie zwischen den Schwenkachsen der Arme und den Halteachsen der Spreizarme liegen. Diese Anordnung ergibt beim Zug an der Aufzugsleine immer eine ausreichende, vom Mast weggerichtete Kraftkomponente, um die Arme aus ihrer senkrechten Ruhelage zu verschwenken. Das anfängliche Spreizen der Arme von Hand ist daher nicht mehr erforderlich. Allerdings können die Anlenkachsen der Spreizarme an den Armen wiederum nicht zu weit nach Außen verlegt werden, da sonst die Arme im eingeklappten Zustand in einem relativ großen Abstand vom Mast zum Liegen kommen, womit der Platzbedarf des zusammengeklappten Wäscheschirmes vergrößert würde.A significant improvement in this regard is achieved in the scrubbing screen according to EP-B1-0 113 789 in that, when the laundry umbrella is folded, the articulation axes of the spreader arms on the arms are clearly outside the imaginary line connecting the pivot axes of the arms and the support axes of the spreader arms. This arrangement results in train on the elevator line always sufficient, directed away from the mast force component to pivot the arms from its vertical rest position. The initial spreading of the arms by hand is therefore no longer necessary. However, the articulation axes of the spreader arms on the arms turn can not be laid too far outward, otherwise the arms come to rest in the folded state at a relatively large distance from the mast, so that the space requirement of the folded laundry umbrella would be increased.
Schließlich ist durch die EP-A2-0 898 007 ein Wäscheschirm bekannt, bei dem die Stützarme über Schwenkarme mit den Tragarmen verbunden sind. Diese Ausführungsform verbessert das Öffnen zumindest aus der Ruhephase nicht wesentlich.Finally, EP-A2-0 898 007 a laundry screen is known in which the support arms are connected via pivot arms with the support arms. This embodiment does not significantly improve the opening, at least from the resting phase.
Aufgabe der Erfindung ist es, einen Wäscheschirm zu schaffen, der beim Aufspannen insbesondere in der Anfangsphase nur einen geringen Kraftaufwand erfordert.The object of the invention is to provide a laundry screen, which requires only a small amount of effort during clamping, especially in the initial phase.
Die Aufgabe wird durch einen Wäscheschirm gelöst, der dadurchThe task is solved by a laundry screen, which thereby

Die erfindungsgemäße Wäschespinne hat den Vorteil, dass sie sich besonders leicht aufspannen lässt.The rotary clothes dryer according to the invention has the advantage that it can be clamped particularly easily.
Durch die Führung entsteht beim Aufwärtsbewegen des Gleitgelenks beispielsweise durch ein Zugseil eine vom Mast weg gerichtete Kraftkomponente, so dass der Aufspreizvorgang durch Überwinden des Todpunktes eingeleitet wird.As a result of the guidance, a force component directed away from the mast, for example, by means of a pull cable, arises during the upward movement of the sliding joint, so that the spreading process is initiated by overcoming the dead center.
Es sind vorteilhafter wies kaum zusätzlichen Bauteile erforderlich.There are advantageously showed hardly any additional components required.
Zudem tritt im geschlossenen Zustand des Wäscheschirms eine Selbsthemmung ein. Dadurch, dass keine beweglichen Teile verwendet werden, entsteht keine zusätzliche Reibung, so dass der Kraftaufwand zum Öffnen des Wäscheschirms auf ein Minimum reduziert wird.In addition, a self-locking occurs in the closed state of the laundry screen. The fact that no moving parts are used, there is no additional friction, so that the force required to open the screen is reduced to a minimum.
In einer Ausführungsform des Wäscheschirms ist das einen Arm und einen Spreizarm verbindende Gelenk und/oder das den Mast und einen Spreizarm verbindende Gelenk und/oder das jeweils einen Arm und das Gleitgelenk verbindende Gelenk in jeweils einer Führungsvorrichtung geführt ist. Die Führungsvorrichtung kann beispielsweise als Linearführung und/oder als Langlochführung und/oder als Schrägkeilführung ausgebildet sein.In one embodiment of the laundry umbrella, the joint connecting an arm and a spreader arm and / or the joint connecting the mast and a spreader arm and / or the joint connecting one arm and the sliding joint are each guided in a respective guide device. The guide device may be formed, for example, as a linear guide and / or as a slot guide and / or as a wedge guide.
In einer Aufführung weist die Schrägkeilführung Magnete auf. In einer Aufführungsform sind die Führungsbahnen gerade ausgebildet. In einer anderen Aufführungsform sind die Führungsbahnen gekrümmt. Durch die Form der Führungsbahn lässt sich der Kraftverlauf beim Aufziehen der Wäschespinne optimal einstellen.In one performance, the oblique wedge guide has magnets. In a performance form, the guideways are straight. In another embodiment, the guideways are curved. Due to the shape of the guideway, the force curve when mounting the rotary dryer can be optimally adjusted.
In einer vorteilhaften Aufführungsform steht die Führungsbahn in einem spitzen Winkel zum Mast.In an advantageous embodiment, the guideway is at an acute angle to the mast.
Die Führungsvorrichtung kann jeweils in und/oder an einem Arm und/oder in und/oder an einem Spreizarm und/oder in und/oder an dem Gleitgelenk angeordnet sein.The guiding device can be arranged in and / or on an arm and / or in and / or on a spreading arm and / or in and / or on the sliding joint.
In einer vorteilhaften Aufführungsform weist die Führungsbahn der Führungsvorrichtung des jeweils das einen Arm und einen Spreizarm verbindende Gelenks einen von Null Grad verschiedenen Winkel zur Führungsbahn den Arm und den Mast verbindenden Gelenks aufweist.In an advantageous embodiment, the guideway of the guide device of the respective joint connecting an arm and a Spreizarm has an angle different from zero degrees to the guideway of the arm and the mast connecting joint.
In einer weiteren Aufführungsform verlaufen die Führungsbahn der Führungsvorrichtung des jeweils das einen Arm und einen Spreizarm verbindende Gelenks weitgehend parallel zur Führungsbahn der Führungsvorrichtung des den Arm und den das Gleitgelenk verbindenden Gelenks.In a further embodiment, the guideway of the guide device of the joint respectively connecting the one arm and a spreading arm extend substantially parallel to the guideway of the guide device of the joint connecting the joint and the joint.
In einer weiteren Aufführungsform ist am Gleitgelenk - vorzugsweise von diesem axial beabstandet - zumindest eine Keilführung vorgesehen, die mit einer Gegenkeilführung an dem Arm bzw. den Armen zusammen wirkt.In a further embodiment, at least one wedge guide is provided on the sliding joint-preferably axially spaced therefrom-which cooperates with a counter-wedge guide on the arm or arms.
Durch die Ausbildung der Führung als Langlochführung eine besonders einfache Fertigung möglich.By forming the guide as a slot guide a particularly simple production possible.
Um die Abspreizstrecke zu vergrößern, ist es vorteilhaft, die Langlochführungen sowohl an den Anlenkachsen als auch an den Trag- und Halteachsen vorzusehen, wobei die Langlochführungen an den Anlenkachsen von innen nach außen, die Langlochführungen der Tragachsen und/oder der Halteachsen von außen nach innen gerichtet sind. Dadurch wird die Kraftkomponente beim Aufspreizvorgang weg vom Mast deutlich vergrößert.In order to increase the Abspreizstrecke, it is advantageous to provide the slot guides on both the pivot axes and the support and support shafts, the slot guides on the pivot axes from the inside out, the slot guides the support shafts and / or the support shafts from outside to inside are directed. As a result, the force component during Aufspreizvorgang away from the mast is significantly increased.
In eine Ausgestaltungsform ist die Führungsvorrichtung als Schrägkeilführung ausgebildet. Es sind sowohl am Mast, als auch an den Stützarmen oder Tragarmen gegeneinander laufende Keilflächen vorgesehen, die beim axialen Anheben des Gleitgelenkes gegeneinander laufen und eine Kraftkomponente weg vom Mast zum Überwinden des Todpunktes beim Aufspreizvorgang bewirken.In one embodiment, the guide device is designed as a diagonal wedge guide. There are both on the mast, as well as on the support arms or Supporting arms provided against each other running wedge surfaces, which run against each other during the axial lifting of the sliding joint and cause a force component away from the mast to overcome the dead center in Aufspreizvorgang.
Schließlich kann die Schrägkeilführung durch zumindest ein Magnetpaar am Mast und ein gegenpoliges Magnetpaar am Trag- beziehungsweise Stützarm gebildet sein. Dadurch wird eine sichere Verriegelung im Ruhezustand und eine zusätzliche Unterstützung beim Aufspreizvorgang gewährleistet.Finally, the inclined wedge guide can be formed by at least one pair of magnets on the mast and a pair of opposite polarity on the support or support arm. As a result, a secure locking at rest and additional support during Aufspreizvorgang is guaranteed.
Eine Erleichterung des Aufspannvorganges wird in einer besonderen Ausführung dadurch erreicht, dass die Tragarme relativ zu den Anlenkachsen der Spreizarme verschiebbar gelagert sind. Dadurch ist es möglich, beim Aufspannvorgang die Tragarme zunächst etwas anzuheben, so dass sie in eine selbstöffnende Winkellage gelangen.A facilitation of Aufspannvorganges is achieved in a particular embodiment in that the support arms are slidably mounted relative to the pivot axes of the spreader arms. This makes it possible, during the clamping operation, first lift the support arms slightly so that they get into a self-opening angular position.
Die Möglichkeit des Anhebens wird in einfacher Weise dadurch erreicht, dass die Anlenkachse in einem Langloch am Tragarm gelagert ist. Es wird damit weder ein zusätzliches Bauteil, noch ein erhöhter Montageaufwand erforderlich.The possibility of lifting is achieved in a simple manner, that the pivot axis is mounted in a slot on the support arm. It is thus neither an additional component, nor an increased installation effort required.
In weiterer Ausgestaltung der Erfindung sind am oberen Ende der Tragarme Rasthaken, die mit - vorzugsweise im und/oder am Haltestern angeordneten - Rastausnehmungen zusammenwirken, vorgesehen. Dadurch wird eine absolut sichere Verriegelung der Tragarme am Mast in der Ruhestellung gewährleistet.In a further embodiment of the invention are at the upper end of the support arms latching hooks, which cooperate with - preferably arranged in and / or on the holding star - recesses provided. This ensures a completely secure locking of the support arms on the mast in the rest position.
Vorzugsweise sind die Rasthaken mit einer Anlaufschräge versehen, so dass sie beim Zusammenfalten des Wäscheschirms automatisch in die Rastausnehmungen gleiten können. Um ein sicheres Einrasten zu gewährleisten können die Rasthaken vorteilhafter Weise mit einer Feder vorgespannt sein.Preferably, the latching hooks are provided with a run-on slope, so that they can automatically slide into the latching recesses during folding of the laundry umbrella. In order to ensure a secure engagement, the latching hook can advantageously be biased by a spring.
Andererseits ist diese Verrastung durch das Anheben der Tragarme aufgrund der Langlöcher problemlos zu lösen. Die Lösung erfolgt praktisch automatisch ohne zusätzlichen Handgriff. In der Zeichnung ist der Erfindungsgegenstand schematisch dargestellt und wird anhand der Figuren nachfolgend beschrieben, wobei gleich wirkende Elemente mit denselben Bezugszeichen versehen sind. Dabei zeigt:On the other hand, this locking is easily solved by lifting the support arms due to the slots. The solution is virtually automatic without additional handle. In the drawing, the subject invention is shown schematically and will be described below with reference to the figures, wherein like-acting elements are provided with the same reference numerals.

Auf einem Mast 1 ist ein Gleitgelenk 2 bezüglich eines Haltesterns 3 verschiebbar, aber arretierbar gelagert. Am Gleitgelenk 2 sind vier Arme 4 über Schwenkachsen 5 schwenkbar gelagert. Zwischen den Armen 4 ist eine nicht dargestellte Wäscheleine gespannt. Die Arme 4 sind über Spreizarme 6 gegen den Haltestern 3 abgestützt. Die Spreizarme 6 sind mittels Anlenkachsen 7 an den Armen 4 und mittels Halteachsen 8 an dem Haltestern 3 gelagert. Durch Verschieben des Gleitgelenkes 2 nach oben werden die Arme 4, wie aus Fig. 2 ersichtlich, gespreizt und der Wäscheschirm wird aufgespannt.On a mast 1, a sliding joint 2 with respect to a holding star 3 slidably but lockable stored. At the sliding joint 2, four arms 4 are pivotally mounted via pivot axes 5. Between the arms 4, a washing line, not shown, is stretched. The arms 4 are supported by spreading arms 6 against the holding star 3. The spreading arms 6 are by means of articulation axes 7 on the arms 4 and by means of holding axles 8 on the holding star 3 stored. By moving the slide joint 2 upwards, the arms 4, as shown in FIG. 2 can be seen spread and the screen is stretched.
Die Anlenkachse 7 läuft in einer Führung 9, die als Langloch im Arm 4 ausgebildet ist. Die Führung 9 ist in einem spitzen Winkel 10 zum Mast 1 angeordnet. Zum Aufspannen des Wäscheschirms ist ein Zugseil 11 vorgesehen, das am Haltestern 3 befestigt ist und über eine Umlenkung 12 am Gleitgelenk 2 läuft.The pivot axis 7 runs in a guide 9, which is formed as a slot in the arm 4. The guide 9 is arranged at an acute angle 10 to the mast 1. For clamping the clothes screen, a pull cable 11 is provided, which is attached to the holding star 3 and runs over a deflection 12 on the sliding joint 2.
Durch Zug in Richtung 13 an diesem Zugseil 11 wird das Gleitgelenk 2 in Richtung 14 angehoben, wodurch der Arm 4 eine Spreizbewegung 15 ausführt, weil der Arm 4 durch die im Winkel angeordnete Führung 9 auf der Anlenkachse 7 gleitend nach außen gedrückt wird. Die Todlage des Spreizgestells 16 wird damit ohne weiteres Zutun und ohne besondere Kraftanstrengung überwunden.By train in the direction of 13 on this pull cable 11, the slide joint 2 is raised in the direction 14, whereby the arm 4 performs a spreading movement 15, because the arm 4 is pressed by the angled guide 9 on the pivot axis 7 sliding outward. The death of the Spreizgestells 16 is thus overcome without further action and without any special effort.
In Fig. 3 ist eine Alternativlösung entsprechend einer Ansicht nach Fig. 1 dargestellt, bei der im Arm 4 eine untere Schrägführung 17 in Form eines Langloches um die Schwenkachse 5 und eine obere Schrägführung 18 im Spreizarm 6 um die Halteachse 8 vorgesehen ist. Dadurch wird beim Zug in Richtung 13 am Zugseil 11 , wie in Fig. 4 dargestellt, eine intensivere Spreizbewegung 15 erzielt. Das Spreizgestell 16 wird noch weiter aus seiner Todlage herausgedrückt.In Fig. 3, an alternative solution according to a view of FIG. 1 is shown, in which a lower oblique guide 17 is provided in the arm 4 in the form of a slot around the pivot axis 5 and an upper inclined guide 18 in the spreading arm 6 about the holding axis 8. As a result, when pulling in the direction 13 on the traction cable 11, as shown in FIG. 4, a more intensive spreading movement 15 is achieved. The Spreizgestell 16 is further pushed out of his death.
In dem Ausführungsbeispiel nach Fig. 5 ist als Führung eine Schrägkeilführung 19 mit einem schrägen Keil 20 am Mast und einem Gegenkeil 21 am Arm 4 vorgesehen. Durch Zug in Richtung 13 am Zugseil 11 wird das Gleitgelenk 2 mit den Armen 4 angehoben. Keil 20 und Gegenkeil 21 gleiten gegeneinander, so dass der Arm 4 die Spreizbewegung 15 ausführt. Diese Bewegung wird durch die Führung 9', wie vorab ausgeführt, weiter unterstützt.In the embodiment of FIG. 5 is provided as a guide a Schrägkeilführung 19 with a sloping wedge 20 on the mast and a counter-wedge 21 on the arm 4. By train in the direction 13 on the traction cable 11, the slide joint 2 is raised with the arms 4. Wedge 20 and counter wedge 21 slide against each other, so that the arm 4 performs the spreading movement 15. This movement is further supported by the guide 9 ', as stated previously.
Nach dem Ausführungsbeispiel gemäß Fig. 6 ist die Schrägkeilführung 19 durch Magnete 22 am Mast und Gegenmagnete 23 an den Armen 4 gebildet. Dabei ist der Magnet 22 in einen Nordpol 24 und Südpol 25 aufgeteilt, während der Magnet 23 eine umgekehrte Aufteilung von Südpol zu Nordpol hat. Dadurch werden die Arme 4 in der Ruhestellung über die gegenpoligen Magnetpaare 22, 23 zusammengehalten, während beim Anheben des Gleitgelenkes 2 in Richtung 14 (Fig. 6) die Magnete 22 und 23 durch das Verschieben in die abstoßende gleichpolige Stellung gleiten. Der Spreizvorgang, ausgelöst durch die Schrägkeilführung 19, wird durch die Magnete zusätzlich unterstützt.According to the embodiment of FIG. 6, the inclined wedge guide 19 is formed by magnets 22 on the mast and counter magnets 23 on the arms 4. In this case, the magnet 22 is divided into a north pole 24 and south pole 25, while the magnet 23 is a reverse division of south pole to north pole Has. Characterized the arms 4 are held together in the rest position on the opposite pole pairs of magnets 22, 23, while lifting the slide joint 2 in the direction 14 (Fig. 6), the magnets 22 and 23 slide by shifting in the repulsive gleichpolige position. The spreading process, triggered by the inclined wedge guide 19, is additionally supported by the magnets.
Nach dem Ausführungsbeispiel gemäß Fig. 7 und Fig. 8 ist die Schrägkeilführung 19 durch eine mit dem Gleitgelenk 2 verbundene Keilführung 26 und eine Gegenkeilführung 27 an den Armen 4 gebildet. Zur Ermöglichung der Axialbewegung in Richtung 14 ist eine Langlochführung 28 im Gleitgelenk 2 für die Schwenkachse 5 vorgesehen.According to the embodiment of FIG. 7 and FIG. 8, the inclined wedge guide 19 is formed by a wedge guide 26 connected to the sliding joint 2 and a counter-wedge guide 27 on the arms 4. To enable the axial movement in the direction 14, a slot guide 28 is provided in the sliding joint 2 for the pivot axis 5.
