Description

Die Erfindung betrifft einen Wäscheschirm gemäß dem Oberbegriff des Patentanspruches 1. Dokument GB 1 325 409 offenbart einen solchen Wäscheschirm.The invention relates to a laundry screen according to the preamble of claim 1. Document GB 1 325 409 discloses such a laundry screen.

Wäscheschirme der gattungsgemäßen Art haben grundsätzlich den Nachteil, dass eine vergleichsweise große Kraft, insbesondere aus der Ruhephase heraus, zum Aufspannen der Arme, die die Wäscheleine tragen, erforderlich ist. Um diesen Nachteil auszugleichen, ist es bekannt, die Aufzugsleine, die am Schiebestem, der die Arme trägt, angreift, über eine Umlenkrolle in der Spitze des Wäscheschirmes zu führen, so dass eine Halbierung der erforderlichen Kraft erfolgt. Damit war allerdings immer noch nicht das Problem gelöst, dass die Arme im Ruhezustand am Mast des Wäscheschirms anliegen und da sie sich natürlich nicht alleine öffnen sollen, mehr oder weniger straff verrastet sind. Die Überwindung dieses Todpunktes erfordert zusätzliche Kraft oder einen zusätzlichen Handgriff, in dem die Arme zunächst von Hand vom Mast ein Stückchen über den Todpunkt hinaus entfernt werden, um dann mit dem eigentlichen Aufspannvorgang zu beginnen.Laundry umbrellas of the generic type generally have the disadvantage that a comparatively large force, in particular from the resting phase, for mounting the arms that carry the clothesline, is required. To compensate for this disadvantage, it is known to guide the elevator line, which acts on the sliding handle, which carries the arms, via a deflection roller in the top of the laundry screen, so that a halving of the required force takes place. However, this still did not solve the problem that the arms lie in the resting state on the mast of the laundry screen and since they are not supposed to open on their own, they are more or less tightly locked. Overcoming this dead center requires additional force or an additional handle in which the arms are first removed by hand from the mast a bit beyond the dead center to then start with the actual Aufspannvorgang.

Durch die EP 0113788 B1 wurde ein Wäscheschirm bekannt, bei dem die Aufzugsleine ebenfalls vom Schiebestern über eine Umlenkrolle in der Mastspitze geführt ist, so dass die Aufzugskraft halbiert ist und bei dem zusätzlich die Spreizarme mit einer Abkröpfung versehen sind, die beim Öffnen eine Vorspreizung der Arme bewirken. Zusätzlich ist eine den Öffnungsvorgang unterstützende Feder um den Mast eingebaut.By EP 0113788 B1, a laundry screen has been known, in which the elevator line is also guided by the sliding star on a pulley in the mast top, so that the elevator force is halved and in addition the spreading arms are provided with an angled portion which opens a pre-spread of the Cause the poor. In addition, a spring supporting the opening process is installed around the mast.

Weiter ist durch die EP 0649935 B ein Wäscheschirm bekannt, bei der im Mast ein Spreizkörper angeordnet ist, der mit Stützelementen zusammenwirkt, die bei einer Längsverschiebung helfen, die Spreizarme aus ihrer eingeklappten Ruhelage herauszuschwenken. Auch diese Maßnahme dient dazu, die Arme beziehungsweise Spreizarme aus dem Ruhezustand in eine Vorab-Spreizung zu bringen, so dass die Kraft an der Aufzugsleine in vertretbaren Grenzen bleibt.Furthermore, EP 0649935 B discloses a laundry screen in which a spreader body is arranged in the mast, which cooperates with supporting elements which, in the event of a longitudinal displacement, help to swivel the spreader arms out of their folded-in rest position. This measure also serves to bring the arms or spreading arms from the idle state into an advance spread, so that the force on the elevator line remains within reasonable limits.

Beide Lösungen sind allerdings vergleichsweise aufwendig und erfordern zusätzliche Bauteile, die mit entsprechender Präzision gefertigt sein müssen.However, both solutions are relatively expensive and require additional components that must be manufactured with appropriate precision.

Aufgabe der Erfindung ist es, eine Möglichkeit zu finden, einen Wäscheschirm mit einfachen Mitteln bereits aus seiner Ruhestellung heraus mit geringem Kraftaufwand und mit einem Handgriff zu öffnen.The object of the invention is to find a way to open a laundry screen with simple means already from its rest position with little effort and with a handle.

Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Die Erkenntnis, gänzlich auf eine Aufzugsleine zu verzichten und wenigstens einen Arm als Aufspannhebel zu verwenden, erlaubt die Nutzung eines äußerst günstigen Hebelverhältnisses, wodurch die aufzuwendende Kraft für den Aufspannvorgang auf 1 bis 2 kp reduziert werden kann. Die Überwindung des Tod- beziehungsweise Beharrungspunktes der Arme im Ruhezustand ist damit total eliminiert. Besonders bemerkenswert ist dabei, dass diese enorme Verbesserung der Bedienung ohne technischen Mehraufwand erreicht werden konnte, im Gegenteil, es wurde durch Einsparung der Aufzugsleine eine drastische Verbilligung erzielt.This object is achieved with the characterizing features of claim 1. The knowledge of completely dispensing with an elevator line and using at least one arm as a clamping lever, allows the use of a very favorable lever ratio, whereby the force to be applied for the Aufspannvorgang can be reduced to 1 to 2 kp. The overcoming of the death or persistence point of the arms at rest is thus totally eliminated. It is particularly noteworthy that this enormous improvement in operation could be achieved without additional technical effort, on the contrary, it was achieved by saving the elevator line a drastic reduction.

Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. Durch einen Griffbereich im äußeren Drittel des Armes wird die Bedienung weiter vereinfacht und insbesondere ist für eine Bedienungsperson, die erstmals einen derartigen Wäscheschirm zu öffnen hat, die neuartige Bedienungsweise sofort klar.Embodiments of the invention are described in the dependent claims. By a grip area in the outer third of the arm, the operation is further simplified and in particular is for an operator who has to open for the first time such a laundry screen, the novel operation immediately clear.

Durch die besondere Geometrie, nach der die Schwenkachse für die Arme über der Anlenkachse für die Spreizarme im geöffneten Zustand liegt, wird eine selbsthemmende Arretierung des Wäscheschirmes in der Gebrauchstellung erreicht. Besonders vorteilhaft ist es dabei, wenn die Arme annähernd waagrecht liegen, so dass von den behängten Wäscheleinen keine Kraftkomponente in Richtung Wäscheschirmschließen ausgeht.Due to the special geometry, according to which the pivot axis for the arms is above the pivot axis for the spreading arms in the open state, a self-locking locking of the laundry screen is achieved in the use position. It is particularly advantageous in this case if the arms are approximately horizontal, so that no force component originates in the direction of the laundry screen closing of the suspended clotheslines.

Durch die Verlegung der Schwenkachsen für die Arme weiter nach Außen, also im größeren Abstand von der Mittellinie des Mastes, werden die Hebelverhältnisse weiter verbessert, so dass ein noch leichteres Öffnen, insbesondere auch bei Wäscheschirmen mit Einzug der Leinen in die Arme, gegeben ist. Zudem hat die zusammenlaufende Anordnung der Arme den Vorteil, dass die Wäscheleinen im Ruhezustand nach innen fallen und somit eine leichte Abdeckung der gesamten Wäschespinne über die verschiedensten Möglichkeiten, wie Klappen, Hauben usw. möglich ist.By laying the pivot axes for the arms farther outward, so at a greater distance from the center line of the mast, the leverage ratios are further improved, so that an even easier opening, especially in linen umbrellas with collection of the lines in the arms, is given. In addition, the converging arrangement of the arms has the advantage that the clotheslines fall in the resting state inside and thus easy coverage of the entire clothes dryer over a variety of ways, such as flaps, hoods, etc. is possible.

Einige Ausführungsbeispiele der Erfindung werden im folgenden anhand der Zeichnungen näher erläutert, wobei die Wäscheschirme jeweils halbseitig in der Ruhe- und in der Arbeitsstellung dargestellt sind.Some embodiments of the invention are explained in more detail below with reference to the drawings, wherein the laundry screens are each half-side shown in the rest and in the working position.

In Fig. 1 ist ein erstes Beispiel eines Wäscheschirmes dargestellt. Dabei ist dieser auf der linken Seite im geschlossenen und auf der rechten Seite im geöffneten Zustand gezeigt.In Fig. 1, a first example of a laundry screen is shown. This is shown on the left side in the closed and on the right side in the open state.

An einem Mast 1 ist ein Schiebestern 2, an dem über Schwenkachsen 3 Arme 4 gelagert sind, geführt.On a mast 1 is a sliding star 2, on which are mounted on pivot axes 3 arms 4, out.

Die Arme 4 sind wiederum über Spreizarme 5, die in Anlenkachsen 6 an den Armen 4 und über Halteachsen 7 in einem Haltestem 8 am Mastende 9 befestigt sind, abgestützt. Der dargestellte Arm 4 ist dabei als Aufspannhebel 10 ausgebildet. Dabei muss der Aufspannhebel so ausgebildet sein, dass die über den Schiebestem 2 auf den Mast 1 wirkende senkrechte Kraftkomponente 36 geringer ist, als die von der Schwenkachse 3 axial zum Mast wirkende Kraftkomponente 23, 37, wobei zusätzlich die Reibung des Schiebesternes 2 zu berücksichtigen ist. Daraus folgt, dass die Gleiteigenschaften Schiebestem 2 zu Mast 1 bei einer entsprechenden Auslegung das Kräfteverhältnis günstig beeinflussen können. In einer bevorzugten Ausführungsform werden diese Verhältnisse dadurch erreicht, dass der Abstand zwischen der Schwenkachse 3 und der Anlenkachse 6 geringer ist, als die Länge des Spreizarmes 5. Dies wird auch dadurch erreicht, dass das Maß 11, also der senkrechte Abstand der Schwenkachse 3 vom Mast 1 geringer ist, als der Abstand 12 der Anlenkachse 6 vom Mast 1. Dabei bewegt sich der Differenzabstand 13 in einer Größenordnung zwischen 3 cm und 15 cm.The arms 4 are in turn supported by spreading arms 5, which are mounted in articulation axes 6 on the arms 4 and on holding axles 7 in a holding eye 8 at the mast end 9. The illustrated arm 4 is designed as a clamping lever 10. In this case, the clamping lever must be designed so that the force acting on the mast 1 over the Schiebestem 2 vertical force component 36 is less than the force acting from the pivot axis 3 axially to the mast force component 23, 37, in addition, the friction of the sliding star 2 is taken into account , It follows that the sliding properties Schiebestem 2 to mast 1 with a corresponding interpretation can affect the balance of power low. In a preferred embodiment, these ratios are achieved in that the distance between the pivot axis 3 and the pivot axis 6 is less than the length of the Spreizarmes 5. This is also achieved in that the dimension 11, ie the vertical distance of the pivot axis 3 of Mast 1 is less than the distance 12 of the pivot axis 6 from the mast 1. In this case, the difference distance 13 moves in an order of magnitude of between 3 cm and 15 cm.

Die Spreizarme 5 sind an den unteren Hälfen 14 auf der Innenseite 15 der Arme 10 über die Anlenkachsen 6 angelenkt.The spreading arms 5 are articulated to the lower half 14 on the inner side 15 of the arms 10 via the pivot axes 6.

Die Arme 4 sind als Aufspannhebel 10 ausgebildet und haben im äußeren Drittel 16 einen Griffbereich 17 zum Aufspannen der Arme 4. Dabei steht zum Aufspannen das Verhältnis des Krafthebels 18 zum Lasthebel 19, sowie zur Lösung aus dem Verharrungspunkt das Verhältnis des Lasthebels 19 zum Differenzabstandshebel 20 zur Verfügung. Dabei wird eine gute Funktion und ein leichtes Spannen der Wäscheleine 21 mit einem Verhältnis Krafthebel 18 zu Lasthebel 19 von etwa 3:1 erreicht. Der Differenzabstand 13 und somit der Differenzabstandshebel zum Lasthebel 19 sollte dabei wenigstens ein Verhältnis von 1:4 haben.The arms 4 are formed as a clamping lever 10 and have in the outer third 16 a handle portion 17 for clamping the arms 4. It stands for clamping the ratio of the power lever 18 to the load lever 19, as well as to solve the point of arrest the ratio of the load lever 19 to the difference distance lever 20th to disposal. In this case, a good function and easy tensioning of the clothesline 21 with a ratio of power lever 18 to load lever 19 of about 3: 1 is achieved. The difference distance 13 and thus the difference distance lever to the load lever 19 should have at least a ratio of 1: 4.

Zum Aufspannen des Wäscheschirmes, also von der Überführung aus der Ruhestellung in die Arbeitsstellung ist es lediglich erforderlich, den Aufspannhebel 10, also den für den Aufspannvorgang vorgesehenen Arm 4, an seinem Griffbereich 17 anzufassen und in Richtung 22 zu ziehen. Dabei wird der Schiebestem 2 nach oben in Richtung 23 gedrückt, der Kraftvektor in Richtung 23 ist größer als der über den Schiebestem 2 senkrecht auf den Mast 1 gerichtete Kraftvektor, bis die auf der rechten Seite dargestellte Lage erreicht und die Wäscheleine 21 gespannt ist. In dieser Stellung wird der Schiebestern 2 am Mast 1 durch eine nicht näher dargestellte Verriegelungseinrichtung 24 verriegelt. Zum Zusammenfalten des Wäscheschirms, also der Überführung aus der Arbeits- in die Ruhestellung ist lediglich die Verriegelung am Mast 1 über eine Verriegelungseinrichtung 24 zu lösen und der Aufspannhebel 10 am Griffbereich 17 hoch zu drücken, wodurch die Arme 4 über den Schiebestem 2 am Mast nach unten in die Ruhestellung gleiten.For mounting the clothes screen, so from the transfer from the rest position to the working position, it is only necessary to touch the Aufspannhebel 10, so provided for the Aufspannvorgang arm 4, at its handle portion 17 and pull in the direction 22. In this case, the Schiebestem 2 is pressed upward in the direction 23, the force vector in the direction 23 is greater than the directed over the Schiebestem 2 perpendicular to the mast 1 force vector until the position shown on the right side reached and the clothesline 21 is stretched. In this position, the sliding star 2 is locked on the mast 1 by a locking device 24, not shown. To fold the laundry umbrella, so the transfer from the working to the rest position is only the lock on the mast 1 via a locking device 24 to release and the clamping lever 10 on the handle portion 17 to push up, causing the arms 4 on the Schiebestem 2 on the mast slide down to the rest position.

Während bei dem Ausführungsbeispiel nach Fig. 1 die Arme 4 in einem spitzen Winkel 25 zum Mast 1 verlaufen, was durch eine Abwinklung 26 am unteren Ende 27 der Arme erreicht wird, sind bei dem Ausführungsbeispiel nach Fig. 2 die Arme 41 parallel zum Mast 1 angeordnet. Um zusätzlich auf eine separate Verriegelungseinrichtung verzichten zu können, wie sie in Fig. 1 durch 24 dargestellt ist, ist bei dem Ausführungsbeispiel nach Fig. 2 die Schwenkachse 3 in einem Abstand 28 in aufgespanntem Zustand des Wäscheschirmes, also in Arbeitsstellung, über der Anlenkachse 6 angeordnet. Die Arme 41 sind dabei waagrecht ausgerichtet.While in the embodiment of FIG. 1, the arms 4 extend at an acute angle 25 to the mast 1, which is achieved by an angling 26 at the lower end 27 of the arms, in the embodiment of FIG. 2, the arms 41 are parallel to the mast arranged. In order to additionally dispense with a separate locking device, as shown in Fig. 1 by 24, in the embodiment of FIG. 2, the pivot axis 3 at a distance 28 in the clamped state of the laundry screen, ie in the working position, on the pivot axis. 6 arranged. The arms 41 are aligned horizontally.

Die übrigen Verhältnisse entsprechen dem Ausführungsbeispiel nach Fig. 1.The other conditions correspond to the embodiment of FIG. 1.

Nach dem Ausführungsbeispiel gemäß Fig. 3 sind die Arme 42 eng anliegend am Mast 1 ausgebildet, während die Anlenkachsen 61 auf der Außenseite 29 der Arme 42 angeordnet sind und somit ebenfalls den Differenzabstandhebel 20 zwischen den Schwenkachsen 3 und den Anlenkachsen 61 erzeugen. Auch der Abstand 28 in Arbeitsstellung des Wäscheschirmes wird dadurch wieder erreicht. Die sonstigen Verhältnisse entsprechen den Ausführungsbeispielen gemäß Fig. 1 und Fig. 2.According to the embodiment of FIG. 3, the arms 42 are formed close fitting on the mast 1, while the pivot axes 61 are arranged on the outer side 29 of the arms 42 and thus also produce the differential distance lever 20 between the pivot axes 3 and the pivot axes 61. The distance 28 in working position of the laundry screen is achieved again. The other conditions correspond to the exemplary embodiments according to FIG. 1 and FIG. 2.

Nach Fig. 4 ist eine Ausführungsform dargestellt, bei der die Spreizarme 51 im Bereich der Anlenkachsen 61 mit einer Abwinklung 30 versehen sind, so dass die Spreizarme 51 im Ruhestand ebenfalls parallel zum Mast 1 des Wäscheschirmes liegen. Dadurch kann eine kompakte Bauweise erreicht werden. Die übrigen Verhältnisse entsprechen wiederum den Ausführungsbeispielen gemäß Fig. 1 bis Fig. 3.4, an embodiment is shown in which the spreading arms 51 are provided in the region of the pivot axes 61 with an angled portion 30, so that the spreading arms 51 are also in retirement parallel to the mast 1 of the laundry screen. This allows a compact design can be achieved. The other conditions again correspond to the exemplary embodiments according to FIGS. 1 to 3.

Nach dem Ausführungsbeispiel gemäß Fig. 5 sind die Arme 43 eng anliegend am Mast 1 ausgebildet und über Spreizarme 5, die in Anlenkachsen 6 auf der Innenseite 15 der Arme 43 und über Halteachsen 7 in dem Haltestem 8 am Mastende 9 befestigt sind, abgestützt.According to the embodiment of FIG. 5, the arms 43 are formed tightly against the mast 1 and supported by spreading arms 5, which are mounted in articulation axes 6 on the inner side 15 of the arms 43 and holding axes 7 in the Haltestem 8 at the mast end 9.

An zumindest einem Arm 43 sind in einem inneren Griffbereich 31 ein axial 32 zum Arm 43 wirkender Griff 33 und im äußeren Griffbereich 17 ein Schwenkgriff 34, der radial 35 zum Arm 43 wirkt, angeordnet. Dabei wird mit dem Griff 33 der Kraftvektor 36 verkleinert entsprechend der auf den Griff 33 ausgeübten Gegenkraft, so dass über den Schwenkgriff 34 der Kraftvektor 37 axial zum Mast 1 größer als der Kraftvektor 36 wird, d.h. , dass zumindest die Reibkraft des Schiebestems 2 überwunden wird, sodass ein Öffnen und Schließen des Wäscheschirmes ohne Aufzugsleine und ohne schwierige Betätigung des Schiebestems 2 in gebückter Haltung auch bei nicht optimalen Hebelverhältnissen ebenfalls nur über den als Aufspannhebel 10 ausgebildeten Arm 43 möglich ist.On at least one arm 43 are in an inner handle portion 31, an axially 32 to the arm 43 acting handle 33 and the outer handle portion 17, a pivoting handle 34 which acts radially to the arm 43 43, respectively. In this case, with the handle 33 of the force vector 36 is reduced in accordance with the force exerted on the handle 33 counterforce, so that via the pivot handle 34, the force vector 37 axially to the mast 1 is greater than the force vector 36, i. in that at least the frictional force of the sliding stop 2 is overcome, so that opening and closing of the laundry screen without an elevator line and without difficult operation of the sliding stop 2 in a stooping posture is also possible, even with non-optimal lever ratios, only via the arm 43 designed as a clamping lever 10.

Schließlich ist in Fig. 6 eine Ausführungsform dargestellt, bei der ein Haltestem 81 mit Halteachsen 7 bis zu einem Anschlag 38, der zur Höheneinstellung des Wäscheleinenverlaufs 21 auch verstellbar sein kann, verschiebbar angeordnet ist. Der Schiebestem 2 ist über einen Grundanschlag 39 nach unten fixiert. Die Hebel- und Kräfteverhältnisse entsprechen den vorab beschriebenen Kriterien.Finally, an embodiment is shown in Fig. 6, in which a Haltestem 81 with holding axles 7 to a stop 38, the height adjustment of the Clotheslines course 21 may also be adjustable, is arranged displaceably. The Schiebestem 2 is fixed via a base stop 39 down. The leverage and power ratios correspond to the criteria described above.

Mit dieser Anordnung ist es möglich, eine Vorspreizung der Arme mit einem noch geringeren Kraftaufwand zu erreichen, wobei je nach Auslegung die Schwerkraft ausreicht.With this arrangement, it is possible to achieve a prespreading of the arms with an even lower expenditure of force, wherein, depending on the design, the force of gravity is sufficient.

Damit kann eine automatische Öffnung des Wäscheschirmes realisiert werden; es ist nur ein Lösen einer nicht dargestellten Verriegelung im Haltestem 81 erforderlich.Thus, an automatic opening of the laundry screen can be realized; it is only a release of a lock, not shown in Haltestem 81 required.
