Abstract

The device has carrying arms (3) joined to a vertical bearer by a sliding joint and supported at the upper end of the bearer by a second joint via spreading arms that hold a washing line fed as line sides. The spreading arms can be moved from an approximately vertical position to an approximately horizontal position in which the line sides are tensioned and in which they can be fixed by a latching lever in the sliding joint. The latching lever and/or sliding joint housing has a holder acted on by at least one carrying arm for holding the lever in the unlocked state during closing of the rotary line and in the locked position.

Description

Die Erfindung betrifft eine Wäschespinne mit an einem vertikalen Träger über ein Gleitgelenk angelenkte Tragarme, die sich über Stützarme an einem zweiten Gelenk am oberen Ende des Trägers abstützen und eine in Seilecken geführte Wäscheleine aufnehmen, wobei die Tragarme durch Verschieben des Gleitgelenkes von einer etwa senkrechten in eine annähernd waagerechte, die Seilecke spannende Stellung überführbar sind, in der sie über einen Rasthebel im Gleitgelenk am Träger kraftschlüssig festlegbar sind.The invention relates to a rotary clothes dryer with hinged to a vertical support via a sliding support arms, which are supported by support arms on a second joint at the upper end of the carrier and record a guided in rope corners clothesline, the support arms by moving the slide joint from an approximately vertical in an approximately horizontal, the corner rope exciting position can be transferred, in which they are non-positively fixed by a locking lever in the sliding joint on the carrier.

Wäschespinnen weisen im Allgemeinen, um große Wäschemengen aufnehmen zu können, im aufgespannten Zustand, also im Betriebszustand, eine nicht unerhebliche Größe auf. Es ist daher üblich, dass sie nach der Benutzung zusammengeklappt werden, um Platz zu sparen. Dabei tritt bei allen derzeit bekannten Wäschespinnen das gleiche Problem auf. Beim Aufspannen wird das Gleitgelenk am Träger nach oben verschoben und wird im gespannten Zustand der Wäscheleine am Träger beziehungsweise an einem am Träger befestigten Teil eingerastet. Dabei ist es üblich, dass mehrere Raststellungen vorhanden sind, um ein Nachspannen z. B. bei sich dehnenden Wäscheleinen zu ermöglichen. Diese Mehrfachrastungen bringen insofern ein Problem, dass beim Zusammenklappen der Wäschespinne der Rasthebel am Gleitgelenk so lange bedient werden muss, bis dieses über die letzte Rastmöglichkeit nach unten verschoben ist. Dabei fallen aber bereits die Wäscheleinen nach innen, so dass ein lästiges Verschlingen der Leinen mit der Bedienperson häufig nicht ausbleibt.In general, in order to be able to absorb large quantities of laundry, rotary dryers have a not inconsiderable size in the clamped state, that is to say in the operating state. It is therefore common that they are folded after use to save space. This occurs in all currently known spin dryers on the same problem. When clamping the slide joint is moved up the carrier and is locked in the tensioned state of the clothesline on the carrier or on a part attached to the carrier. It is common that several locking positions are available to retighten z. B. to allow for stretching clotheslines. This multiple catching bring a problem in that when folding the rotary clothes dryer the locking lever on the sliding joint must be operated until it is moved over the last possibility of rest down. However, the clothes lines are already falling inwards, so that annoying entanglement of the lines with the operator often does not fail.

Aus CH 388 894 A ist eine Vorrichtung zum Festhalten mindestens einer verschiebbar an einer vertikalen Stange gelagerten Hülse bei schirmartig zusammenklappbaren Wäscheaufhängevorrichtungen bekannt. Die Vorrichtung beinhaltet unter anderem eine an der vertikalen Stange angeordnete Zahnstange, in die ein Greifer zum vorübergehenden Festlegen der Hülse eingreifen kann. Zur Bedienung des Greifers ist ein Bedienhebel vorgesehen. Zum Lösen des Greifers aus der Zahnstange muss der Bedienhebel von Hand bedient werden. Außerdem muss der Bedienhebel dann erneut von Hand bedient werden, um ein Arretieren in einer wieder herbeizuführenden Öffnungsstellung des Wäschetrocknungsgestells zu bewirken.Out CH 388 894 A is a device for holding at least one slidably mounted on a vertical rod sleeve in screen-like collapsible Wäschehhängevorrichtungen known. The device includes, among other things, a rack arranged on the vertical bar into which a gripper can temporarily engage the sleeve. To operate the gripper, an operating lever is provided. To release the gripper from the rack, the operating lever must be operated by hand. In addition, the operating lever must then be operated manually again to effect locking in a re-opening position of the laundry drying rack.

CH 388 240 A offenbart eine Wäscheaufhängevorrichtung, die mit einem unter Federwirkung stehenden Verriegelungsorgan ausgerüstet ist, das unter dem Einfluss eines Betätigungsorgans steht. CH 388 240 A discloses a Wäschehhängevorrichtung, which is equipped with a spring-loaded locking member, which is under the influence of an actuator.

GB 1 411 055 A offenbart eine Wäschespinne, die einen Verriegelungshebel aufweist, der wahlweise in eine Arretierungs- oder Freigabestellung von Hand überführt werden kann. GB 1 411 055 A discloses a clothes dryer having a locking lever which can be selectively transferred to a locking or release position by hand.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Wäschespinne der eingangs genannten Art zu schaffen, die einfacher bedienbar ist.
Diese Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst.The invention is therefore an object of the invention to provide a rotary dryer of the type mentioned, which is easier to use.
This object is solved by the subject matter of patent claim 1.

Durch diese Halteeinrichtung genügt es, daß beim Zusammenklappen der Wäschespinne der Rasthebel nur zum Lösen der Verrastung kurz bedient werden muß und danach stabil in der entriegelten Stellung verharrt, so daß der eigentliche Falt- beziehungsweise Klappvorgang z. B. über einen Tragarm erfolgen kann. Ein Kontakt beziehungsweise ein Verhädem mit der Wäscheleine ist dadurch zuverlässig ausgeschlossen. Eine zusätzliche Bedienungserleichterung wird dadurch erreicht, daß das zweite Gelenk am oberen Ende des Trägers ebenfalls verstellbar ist und zumindest im aufgespannten Zustand der Wäschespinne mit dem Gleitgelenk kraftschlüssig verbunden ist. Dadurch ist es möglich, die Höhe der Wäscheleine im aufgespannten Zustand der Größe der diese bedienenden Person anzupassen. Ein weiterer Vorteil ist darin zu sehen, daß das gesamte Spreizgestell zum Transport der Wäschespinne am Träger verschiebbar ist, so daß der Träger der Wäschespinne die Gesamtgröße des Versandpaketes bestimmt. Die Tragarme stehen im zusammengeklappten Zustand nicht über den Träger über.By this holding device it is sufficient that when folding the rotary clothes dryer the locking lever only to release the latch must be operated briefly and then remains stable in the unlocked position, so that the actual folding or folding operation z. B. can be done via a support arm. A contact or a Verhädem with the clothesline is thereby reliably excluded. An additional ease of operation is achieved in that the second joint at the upper end of the carrier is also adjustable and at least in the clamped state of the rotary clothes dryer is non-positively connected to the sliding joint. This makes it possible to adjust the height of the clothesline in the clamped state of the size of the person using it. Another advantage is the fact that the entire spreading frame for transporting the rotary dryer on the carrier is displaceable, so that the carrier of the rotary dryer determines the total size of the shipping package. The support arms are in the folded state not on the carrier over.

Weitere Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. So ist es besonders vorteilhaft, die Rastung über eine Zahnstange, die im zweiten, also oberen Gelenk befestigt und mit diesem verschiebbar ist, zu verwenden, weil dadurch eine besonders feinstufige Verstellung und Spannung der Wäschespinne möglich wird. Diese Zahnstange ist auch leicht in einer Nut des Trägers zu führen.Further embodiments of the invention can be found in the dependent claims. Thus, it is particularly advantageous to use the detent via a rack, which is mounted in the second, ie upper hinge and slidable with this, because thereby a particularly fine-scale adjustment and tension of the clothes dryer is possible. This rack is also easy to guide in a groove of the wearer.

Eine besonders kostengünstige Lösung wird dadurch erreicht, daß der Rasthebel über ein Langloch am Gleitgelenkgehäuse gelagert ist, wobei um den Lagerbolzen eine Schenkelfeder angeordnet ist, deren beide Schenkel versuchen, den Rasthebel in Eingriffstellung als auch bei einmaliger Handbetätigung in geöffneter Stellung zu halten.A particularly cost-effective solution is achieved in that the locking lever is mounted on a slot on Gleitgelenkgehäuse, wherein about the bearing pin a leg spring is arranged, the two legs try to keep the locking lever in the engaged position and in a single manual operation in the open position.

Natürlich ist es auch möglich, eine quer auf den Träger wirkende Feder und eine zweite längs des Trägers ausgerichtete Feder zu verwenden. Dadurch ist es möglich, unterschiedliche Federstärken für diese beiden unterschiedlichen Aufgaben zu verwenden.Of course, it is also possible to use a spring acting transversely on the carrier and a second spring aligned along the carrier. This makes it possible to use different spring strengths for these two different tasks.

Durch entsprechende Ausbildung der Zahnstange mit waagerechten Zahnflanken wird eine besonders sichere Verrastung erreicht. Dabei ist es auch hilfreich, am Rasthebel mehrere Gegenzähne vorzusehen.By appropriate design of the rack with horizontal tooth flanks a particularly secure locking is achieved. It is also helpful to provide several locking teeth on the locking lever.

Beim oberen Gelenk ist es vorteilhaft, den Bolzenhebel mit einer Winkelkerbe zu versehen, um diesen sicher in den Rastlöchern im Träger zu halten. Diese Rastlöcher sind versetzt zu der Nut für die Zahnstange vorgesehen, um eine Behinderung durch die Stützarme zu vermeiden.In the case of the upper joint, it is advantageous to provide the bolt lever with an angle notch in order to hold it securely in the latching holes in the carrier. These locking holes are offset from the groove for the rack provided to prevent obstruction by the support arms.

Die Fig. 1 zeigt - wie auch alle weiteren Figuren in schematisierter Darstellung - eine Wäschespinne mit einem vertikalen Träger 1, an dem über ein Gleitgelenk 2 Tragarme 3 angelenkt sind, die sich über Spreizarme 4 an einem zweiten Gelenk 5 am oberen Ende 6 des Trägers 1 abstützen und eine in Seilecken geführte Wäscheleine, die hier der Einfachheit halber nicht dargestellt ist, aufnehmen.The Fig. 1 shows - as well as all other figures in a schematic representation - a rotary clothes dryer with a vertical support 1, on which are hinged via a slide joint 2 support arms 3, which are supported by spreading arms 4 at a second joint 5 at the upper end 6 of the support 1 and a in rope corners guided clothesline, which is not shown here for simplicity record.

Fig. 2 zeigt das Gleitgelenk 2 am Träger 1 mit einem Tragarm 3, wobei nur die eine Hälfte dargestellt ist. Das Gleitgelenk 2 nimmt zwischen zwei Wänden 7, zwischen denen ein Bolzen 8 verläuft, einen Rasthebel 9 auf. Der Rasthebel 9 ist als zweiarmiger Hebel ausgebildet und über ein Langloch 10 auf dem Bolzen 8 gelagert. Der untere Hebelarm 11 ist auf der Innenseite mit Zähnen 12 versehen, die in eine Zahnstange 13 eingreifen und sich auf den waagerechten Zahnflanken 14 abstützen. Zusätzlich ist in diesem Hebelarm 11 eine Längsdruckfeder 15 angeordnet, die sich am Bolzen 8 und einem Verbindungssteg 16 zwischen den beiden Wänden 7 abstützt. Fig. 2 shows the sliding joint 2 on the support 1 with a support arm 3, wherein only one half is shown. The sliding joint 2 takes between two walls 7, between which a bolt 8 extends, a locking lever 9. The locking lever 9 is formed as a two-armed lever and mounted on a slot 10 on the bolt 8. The lower lever arm 11 is provided on the inside with teeth 12 which engage in a rack 13 and are supported on the horizontal tooth flanks 14. In addition, a longitudinal compression spring 15 is arranged in this lever arm 11, which is supported on the bolt 8 and a connecting web 16 between the two walls 7.

Der obere Hebelarm 17 des Rasthebels 9 hat beidseitig Nockenansätze 18, die auf der waagerechten Auflagefläche 19, gebildet durch das obere Ende der Wände 7, aufliegt. Die Auflagefläche 19 geht in eine Mulde 20 über, deren Tiefe dem Bolzenspielraum 21 im Langloch 10 entspricht.The upper lever arm 17 of the locking lever 9 has on both sides cam lugs 18 which rests on the horizontal bearing surface 19, formed by the upper end of the walls 7. The support surface 19 merges into a trough 20 whose depth corresponds to the bolt clearance 21 in the slot 10.

Die Zahnstange 13 ist in einer Nute 22 mit Hinterschnitt im Träger 1 eingelegt und geführt und, wie in der Fig. 6 dargestellt, mit dem oberen zweiten Gelenk 5 verbunden. Natürlich ist es auch möglich, bei einer Ausführungsform einer Wäschespinne ohne bewegliches zweites Gelenk die Zahnstange 13 über geeignete Mittel fest mit dem Träger 1 zu verbinden.The rack 13 is inserted and guided in a groove 22 with undercut in the carrier 1 and, as in the Fig. 6 shown connected to the upper second hinge 5. Of course, it is also possible, in one embodiment of a rotary drier without moving second joint, the rack 13 to connect by suitable means fixed to the carrier 1.

Fig. 2 zeigt die verriegelte Stellung des Gleitgelenkes bei aufgespannter Wäschespinne, also in Gebrauchsstellung. Fig. 2 shows the locked position of the sliding joint with clamped clothes dryer, so in the use position.

Zum Zusammenfalten der Wäschespinne betätigt die Bedienungsperson die Taste 23 in Pfeilrichtung 24 gegen die Kraft der Querdruckfeder 25, die sich am Gleitgelenk 2 und dem oberen Hebelarm 17 abstützt und löst die Zähne 12 aus der Zahnstange 13. Dabei gleiten die Nockenansätze 18 in die Mulde 20, gleichzeitig drückt die Längsdruckfeder 15 den Rasthebel 9 in Richtung 26 nach unten und hält ihn in der Mulde 20. Diese Phase ist in der Fig. 3 dargestellt. In dieser entriegelten Stellung der Wäschespinne können die Tragarme 3 beigeklappt werden, was zur Folge hat, daß das Gleitgelenk 2 nach unten fährt. Die Taste 23 muß dabei nicht mehr gehalten werden.For folding the clothes dryer, the operator actuates the button 23 in the direction of arrow 24 against the force of the transverse compression spring 25, which is supported on the sliding joint 2 and the upper lever arm 17 and releases the teeth 12 from the rack 13. The cam lugs 18 slide into the trough 20th , at the same time pushes the Longitudinal compression spring 15, the locking lever 9 in the direction 26 down and holds him in the trough 20. This phase is in the Fig. 3 shown. In this unlocked position of the rotary clothes dryer, the support arms 3 can be folded, with the result that the sliding joint 2 moves down. The key 23 does not have to be held.

In Fig. 4 ist der geschlossene Zustand der Wäschespinne dargestellt. Die Tragarme 3, es sind zwei gegenüberliegende Tragarme dargestellt, liegen annähernd parallel zum Träger 1. In diesem Zustand drückt eine Anlaufschräge 27 am Tragarmgelenk 28 den Rasthebel 9 gegen den Druck der Längsdruckfeder 15 in Richtung 29 nach oben, so daß die Nockenansätze 18 frei werden und durch die Querdruckfeder 25 auf die Auflageflächen 19 geschoben werden. Die Zähne 12 greifen wieder in die Zahnstange ein, wodurch die Wäschespinne wieder verrastet und im Ruhezustand ist.In Fig. 4 the closed state of the rotary dryer is shown. The support arms 3, there are two opposite support arms are shown, are approximately parallel to the carrier 1. In this state, a run-on slope 27 on Tragarmgelenk 28 pushes the locking lever 9 against the pressure of the longitudinal compression spring 15 in the direction 29 upwards, so that the cam lugs 18 are free and be pushed by the transverse compression spring 25 on the support surfaces 19. The teeth 12 engage again in the rack, causing the rotary dryer is locked again and at rest.

Fig. 5 zeigt eine Alternativlösung in einer Darstellungsform gemäß der Fig. 4. Um den Bolzen 8 ist eine Schenkelfeder 30 gelegt, die sich mit einem senkrechten Schenkel 31 an der Rückwand 32 des Gleitgelenkes 2 abstützt und mit ihrem waagerechten Schenkel 33 an einer Zwischenwand 34 im unteren Hebelarm 11. Somit wird durch den waagerechten Schenkel 33 der Schenkelfeder 30 die Funktion der Längsdruckfeder 15 und durch den senkrechten Schenkel 31 die Funktion der Querdruckfeder 25 gemäß Fig. 4 übernommen. Fig. 5 shows an alternative solution in a representation according to the Fig. 4 , To the bolt 8 is a leg spring 30 is placed, which is supported with a vertical leg 31 on the rear wall 32 of the slide joint 2 and with its horizontal leg 33 at an intermediate wall 34 in the lower lever arm 11. Thus, by the horizontal leg 33 of the leg spring 30th the function of the longitudinal compression spring 15 and by the vertical leg 31, the function of the cross-pressure spring 25 according to Fig. 4 accepted.

In Fig. 6 ist das zweite Gelenk 5 am oberen Ende des Trägers 1 dargestellt. Dieses Gelenk 5 ist im vorliegenden Fall ebenfalls verschiebbar ausgebildet. Natürlich ist es möglich, dieses auch fest zu gestalten. Das Gelenk 5 ist über einen Bolzenhebel 35, der ebenfalls als zweiarmiger Hebel ausgebildet ist und um einen Bolzen 39 schwenkt, festgelegt. Dazu sind im Träger 1 Rastlöcher 36 vorgesehen, in die ein am Bolzenhebel 5 eingesetzter Bolzenstift 37 mit Winkelkerbe 38 eingreift. Der Bolzenhebel 35 wird über eine Feder 40 in Raststellung gehalten. Auf den Bolzen 39 wirken beim Spannen des Gleitgelenkes 2 Kräfte in Richtung 41 nach oben und beim Beladen der Wäschespinne Kräfte in Richtung 42 nach unten. Aus diesen Kräften resultieren Kraftkomponenten 43 beim Spannen und 44 beim Beladen.In Fig. 6 the second joint 5 is shown at the upper end of the carrier 1. This joint 5 is also designed to be displaceable in the present case. Of course it is possible to fix this too. The joint 5 is defined by a bolt lever 35, which is also designed as a two-armed lever and pivots about a pin 39. For this purpose, 1 detent holes 36 are provided in the carrier, in which engages a bolt pin 5 inserted on the pin pin 37 with angle notch 38. The bolt lever 35 is held by a spring 40 in the locking position. On the bolt 39, forces act in the direction 41 upwards during the tensioning of the sliding joint 2 and forces in the direction 42 downwards when the clothes dryer is loaded. These forces result in force components 43 during tensioning and 44 during loading.

Die Kraftkomponente beim Spannen über das Gleitgelenk bewirkt ein Lösen des Bolzenhebels 35, was durch die Winkelkerbe 38 verhindert wird.The force component during clamping via the sliding joint causes a release of the bolt lever 35, which is prevented by the angle notch 38.

An diesem Gelenk 5 ist die Zahnstange 13 befestigt und in der Nute 22, die z. B. schwalbenschwanzförmig ausgebildet sein kann, geführt. Die Länge der Zahnstange kann so gewählt werden, daß sie auch im Ruhezustand der Wäschespinne mit dem Gleitgelenk 2 im Eingriff steht. Dadurch wird allerdings der Verstellbereich des Spreizgestelles 45 verringert, sodaß man die Länge der Zahnstange 13 so wählt, daß ihr Eingriff mit dem Gleitgelenk 5 erst im letzten Drittel des Aufspannvorganges erfolgt.At this joint 5, the rack 13 is fixed and in the groove 22, the z. B. may be formed dovetailed out. The length of the rack can be chosen so that it is in the resting state of the rotary clothes dryer with the sliding joint 2 in engagement. As a result, however, the adjustment of the Spreizgestelles 45 is reduced, so that one chooses the length of the rack 13 so that their engagement with the sliding joint 5 takes place only in the last third of the Aufspannvorganges.
