Stiel für HaushaltsgeräteHandle for household appliances
Technisches GebietTechnical field
Die Erfindung betrifft einen Stiel für Haushaltsgeräte, insbesondere für Bodenpflegegeräte, bei deren Betätigung über den Stiel auch eine Drehbewegung übertragen werden muß.The invention relates to a handle for household appliances, in particular for floor care devices, when they are actuated, a rotary movement must also be transmitted via the handle.
Stand der TechnikState of the art
Die bislang von der Anmelderin verwendeten Stiele fürThe handles previously used by the applicant for
Wischmops weisen eine runde Außenkontur auf und entsprechen damit den allgemein üblichen, gedrehten Holzstielen oder den runden Stielen aus Metall oder Kunststoff für Besen, Schrubber oder ähnliches.Mops have a round outer contour and thus correspond to the commonly used, turned wooden handles or the round handles made of metal or plastic for brooms, scrubbers or the like.
Diese Stiele haben den Nachteil, daß bei Übertragung einer Drehbewegung, entweder isoliert oder mit einer Wischbewegung überlagert, der Benutzer den Kraftschluß allein dadurch herstellt, daß der Stiel entsprechend fest umgriffen und somit ein Reibschluß hergestellt wird. Eine Drehbewegung ist beispielsweise zum Andrücken eines Wischmops in einem über dem Eimer gehängten Sieb erforderlich.These handles have the disadvantage that when a rotary movement is transmitted, either insulated or overlaid with a wiping movement, the user creates the frictional connection only by gripping the handle accordingly and thus producing a frictional connection. A rotary movement is required, for example, to press a mop in a sieve suspended above the bucket.
Besonders beim Einsatz für eine nasse Anwendung konzipier- ten Haushaltsgeräten ist nach einem Auswringen von Hand wegen des Feuchtigkeitsfilms die Reibung stark vermindert, so daß ein zusätzlicher Kraftaufwand erforderlich ist, um die Drehbewegung zu erzeugen.Particularly when used for household appliances designed for wet use, the friction is greatly reduced after wringing out by hand due to the moisture film that additional effort is required to produce the rotary motion.
Darüber hinaus besteht die Gefahr der Blasenbildung an den Händen des Benutzers, der den Stiel durch Reibschluß verdreht, da verschiedene Hautschichten gegeneinander verschoben werden können.In addition, there is a risk of blistering on the hands of the user, who twists the handle by friction, since different layers of skin can be shifted against each other.
Aufgabe der Erfindung ist es, einen Stiel für Haushaltsge- rate zu schaffen, der diese Nachteile vermeidet.The object of the invention is to provide a handle for household appliances which avoids these disadvantages.
Darstellung der ErfindungPresentation of the invention
Mit einer polygonalen Außenkontur, bestehend aus Seitenflä- chen und Kanten, kann sich die Hand des Benutzers auf den Seitenflächen abstützen und im Bereich der Kanten einen gewissen Formschluß herbeiführen. Die erforderliche Greif- kraft zur Erzeugung des Reibschlusses kann verringert werden, wodurch der Gefahr der Blasenbildung entgegengewirkt wird. Der Stiel kann aus Holz, Kunststoff, Metall oder anderem Material bestehen.With a polygonal outer contour, consisting of side surfaces and edges, the hand of the user can rest on the side surfaces and bring about a certain positive fit in the area of the edges. The gripping force required to generate the frictional connection can be reduced, which counteracts the risk of blistering. The handle can be made of wood, plastic, metal or other material.
In vorteilhafter Weise weist die Außenkontur zwei bis vier Seitenflächen und eine entsprechende Anzahl Kanten auf. Als besonders günstig herausgestellt hat sich eine Außenkontur mit drei Seitenflächen und drei Seitenkanten, da hier der Kompromiß zwischen einer guten Greifbarkeit und einer guten Kraftübertragung erreicht wird. Entscheidend ist hier der zwischen zwei benachbarten Seitenflächen eingeschlossene Winkel, der für eine gute Greifbarkeit so stumpf wie möglich und für eine gute Kraftübertragung so spitz wie möglich sein soll. Bei drei Seitenflächen beträgt der eingeschlossene Winkel ungefähr 60°, bei vier Seitenflächen ungefähr 90°. Zur Verminderung des Gewichts ist in dem Stiel eine Höhlung vorgesehen, wobei die Innenkontur des Stiels seiner Außenkontur entspricht. Vorzugsweise wird als Material Metall oder Kunststoff eingesetzt.The outer contour advantageously has two to four side surfaces and a corresponding number of edges. An outer contour with three side surfaces and three side edges has proven to be particularly favorable, since here the compromise between good grip and good power transmission is achieved. The decisive factor here is the angle enclosed between two adjacent side surfaces, which should be as obtuse as possible for good grip and as pointed as possible for good power transmission. With three side surfaces the included angle is approximately 60 °, with four side surfaces approximately 90 °. In order to reduce the weight, a hollow is provided in the handle, the inner contour of the handle corresponding to its outer contour. Metal or plastic is preferably used as the material.
Um die Länge des Stiels verändern zu können weist der Stiel mehrere lösbar miteinander verbundene Stielsegmente gleicher Außenkontur auf, in deren Höhlung Kupplungselemente angeordnet sind. Die Kupplungselemente ragen teilweise über das Stielsegment hinaus, um mit diesem Teil in das nächstfolgende Stielsegment einzugreifen. Diese mehrteilige Ausführung hat auch beim Transport des Stiels Vorteile, nämlich eine deutlich geringere Länge als der zusammengebaute Stiel. Durch die polygonale Innenkontur der Stielsegmente ist das Kupplungselement, welches die polygonale Kontur aufgreift, durch Formschluß gegen Verdrehen gesichert, so daß weitere Sicherungsmaßnahmen zur Übertragung des Drehmomentes, beispielsweise Verkleben, nicht erforderlich sind. Die in dem Kupplungselement vorgesehene Rastmittel zur axialen Festlegung der Stielsegmente gegeneinander werden nicht auf Drehung, sondern nur auf axiale Belastung beansprucht.In order to be able to change the length of the stem, the stem has a plurality of stem segments of the same outer contour which are detachably connected to one another and in whose cavity coupling elements are arranged. The coupling elements protrude partially beyond the stem segment in order to engage with this part in the next stem segment. This multi-part design also has advantages when transporting the handle, namely a significantly shorter length than the assembled handle. Due to the polygonal inner contour of the stem segments, the coupling element, which picks up the polygonal contour, is secured against twisting by positive locking, so that further securing measures for transmitting the torque, for example gluing, are not required. The locking means provided in the coupling element for axially fixing the arm segments against one another are not subjected to rotation, but only to axial loading.
In einer Weiterbildung besteht der Stiel aus einem Füh- rungsrohr und einer darin geführten Teleskopstange, wobei die Teleskopstange eine dem Führungsrohr in der Form entsprechende Außenkontur geringerer Abmessung aufweist und mittels einer Arretiervorrichtung im Führungsrohr in verschiedenen Positionen festgestellt wird. Mit Teleskopspie- geln ist eine variable Veränderung der Stiellänge möglich. Gegenüber bekannten Teleskopstielen besteht der Vorteil darin, daß die Arretiervorrichtung lediglich axiale Kräfte aufnehmen muß, da die Drehbewegung durch Formschluß übertragen wird. Bei bekannten Stielen, bei denen die Verriege- lung der Teleskopstange durch Festdrehen eines Spannkonus erfolgt, besteht die Gefahr, daß der Benutzer bei der Betätigung des Haushaltsgeräts nicht auf die Drehrichtung der Drehbewegung achtet und somit den Spannkonus löst.In a further development, the handle consists of a guide tube and a telescopic rod guided therein, the telescopic rod having an outer contour of smaller shape corresponding to the guide tube and being fixed in different positions by means of a locking device in the guide tube. Telescopic mirrors can be used to vary the length of the handle. The advantage over known telescopic handles is that the locking device only has to absorb axial forces, since the rotary movement is transmitted by positive locking. In known handles in which the telescopic rod is locked by tightening a clamping cone takes place, there is a risk that the user does not pay attention to the direction of rotation of the rotary motion when actuating the household appliance and thus loosens the clamping cone.
Eine andere Weiterbildung besteht darin, daß das dem Benutzer zugewandte Stielende mit einer arretierbaren Kappe versehen ist, welche gegenüber dem Stielende axial verschiebbar geführt und in mindestens zwei Positionen gehalten ist. Dadurch wird eine Veränderung der Stiellänge ermöglicht. Auch hier wird von dem Prinzip des Formschlusses zur Übertragung der Drehbewegung Gebrauch gemacht, um eine aus dem DE GM 94 107 91 bekannte Kappe bezüglich ihrer Drehbelastbarkeit zu verbessern. Die Rastvorrichtung wird auch hier nur auf Längsbelastungen beansprucht.Another development is that the handle end facing the user is provided with a lockable cap which is axially displaceable relative to the handle end and is held in at least two positions. This enables the stem length to be changed. Here, too, use is made of the principle of positive locking for the transmission of the rotary movement in order to improve a cap known from DE GM 94 107 91 with regard to its torsional strength. The locking device is also only stressed on longitudinal loads.
Durch die polygonale Außenkontur des Stiels kann zudem auf zusätzliche, die Reibung erhöhende Reibelemente, beispielsweise Gummiringe, verzichtet werden.The polygonal outer contour of the handle means that additional friction elements, for example rubber rings, which increase the friction can also be dispensed with.
Kurzbeschreibung der ZeichnungBrief description of the drawing
Die Erfindung ist anhand eines Teleskopstiels sowie eines aus mehreren Stielsegmenten zusammenbaubaren Stiels in der Zeichnung dargestellt. Es zeigt die: Fig. 1 einen Teleskopstiel mit verriegelter Arretiervorrichtung, die Fig. 2 einen Schnitt längs der Linie A-A aus Fig. 1, die Fig. 3 den Teleskopstiel mit entriegelter Arretiervorrichtung, die Fig. 4 ein Stielsegment eines aus mehreren Stielsegmenten zusammenbaubaren Stiels, die Fig.5 eine Kappe zum Aufsetzen auf das Stielende, die Fig. 6 einen Schnitt durch das Stielende mit aufgesetzter Kappe längs der Linie B-B aus Fig. 5. Ausführung der ErfindungThe invention is shown in the drawing using a telescopic handle and a handle that can be assembled from several handle segments. 1 shows a telescopic handle with a locked locking device, FIG. 2 shows a section along the line AA from FIG. 1, FIG. 3 shows the telescopic handle with an unlocked locking device, and FIG. 4 shows a handle segment of a handle that can be assembled from several handle segments 5 shows a cap for placing on the stem end, FIG. 6 shows a section through the stem end with the cap attached along the line BB from FIG. 5. Implementation of the invention
In Fig. 1 ist ein Teleskopstiel aus Metall dargestellt, welcher ein Führungsrohr 1 und ein Teleskoprohr 2 umfaßt. Das Teleskoprohr 2 ragt in eine Höhlung la des Führungsrohres 1 hinein und ist in diesem mittels einer Führungsteils 3 geführt. Das Führungsteil 3 ist wiederum in dem hohlen Teleskoprohr 2 festgelegt.In Fig. 1, a telescopic handle made of metal is shown, which comprises a guide tube 1 and a telescopic tube 2. The telescopic tube 2 protrudes into a cavity la of the guide tube 1 and is guided therein by means of a guide part 3. The guide part 3 is in turn fixed in the hollow telescopic tube 2.
Sowohl die Außenkontur 4 als auch die Innenkontur 5 des Führungsrohres 1 bzw. des Teleskoprohres 2 sind als Polygon mit drei schwach konkav gekrümmten Seitenflächen 6 und drei stark konkav gekrümmten Kanten 7 ausgebildet (Fig. 2) .Both the outer contour 4 and the inner contour 5 of the guide tube 1 and of the telescopic tube 2 are designed as polygons with three slightly concave curved side surfaces 6 and three strongly concave curved edges 7 (FIG. 2).
Das Teleskoprohr 2 ist auf einer Kante 7 mit Einbuchtungen 8 versehen, welche in regelmäßigen Abständen angeordnet sind. Dabei ist es beliebig, an welcher Stelle die Einbuchtungen 8 zu liegen kommen. Die Einbuchtungen 8 wirken mit einer in Fig. 1 dargestellten Arretiervorrichtung 9 zusammen.The telescopic tube 2 is provided on an edge 7 with indentations 8 which are arranged at regular intervals. It is arbitrary at which point the indentations 8 come to rest. The indentations 8 interact with a locking device 9 shown in FIG. 1.
Die Arretiervorrichtung 9 ist auf das das Teleskoprohr 2 aufnehmende Ende des Führungsrohrs 1 gesteckt und weist ei- nen ersten Abschnitt 10 auf, welcher das Führungsrohr eng umschließt. Der Abschnitt 10 ist durch Reibschluß mit dem Führungsrohr 1 verbunden. An den Abschnitt 10 schließt sich der zweite Abschnitt 11 an, welcher ein gegenüber dem ersten Abschnitt 10 reduziertes Innenmaß aufweist, so daß zwischen dem ersten und dem zweiten Abschnitt 10, 11 einThe locking device 9 is plugged onto the end of the guide tube 1 receiving the telescopic tube 2 and has a first section 10 which tightly surrounds the guide tube. The section 10 is connected to the guide tube 1 by friction. The section 10 is adjoined by the second section 11, which has a reduced internal dimension compared to the first section 10, so that between the first and the second section 10, 11
Absatz 12 entsteht. Der erste Abschnitt 10 der Arretiervorrichtung 9 ist soweit auf das Führungsrohr 1 geschoben, daß dieses auf dem Absatz 12 aufsitzt. Durch die reibschlüssige Verbindung, die grundsätzlich auch durch Kleben oder in an- derer Weise erfolgen kann, ist damit die axiale Lage der ArretierVorrichtung festgelegt. Der zweite Abschnitt 11 der Arretiervorrichtung 9 weist eine der Außenkontur 4 des Teleskoprohrs 2 entsprechende Innenkontur auf, wobei das Teleskoprohr 2 mit Spiel geführt wird. Um den zweiten Abschnitt 11 herum erstreckt sich eine Hülse 13 , die zwischen zwei Anschlägen 14 , 15 längs des zweiten Abschnitts 11 axial verschiebbar ist.Paragraph 12 is created. The first section 10 of the locking device 9 is pushed so far onto the guide tube 1 that it sits on the shoulder 12. The axial position of the locking device is thus determined by the frictional connection, which can in principle also be done by gluing or in some other way. The second section 11 of the locking device 9 has an inner contour corresponding to the outer contour 4 of the telescopic tube 2, the telescopic tube 2 being guided with play. A sleeve 13 extends around the second section 11 and is axially displaceable along the second section 11 between two stops 14, 15.
Weiterhin ist der zweite Abschnitt 11 mit einer Öffnung 16 zur Aufnahme einer Kugel 17 versehen. Der Durchmesser der Kugel 17 ist so gewählt, daß die Kugel in die Einbuchtung 8 des Teleskoprohrs 2 eingreift und von der Hülse 13 beim Herausgleiten aus der Öffnung 16 gehindert wird.Furthermore, the second section 11 is provided with an opening 16 for receiving a ball 17. The diameter of the ball 17 is chosen so that the ball engages in the indentation 8 of the telescopic tube 2 and is prevented by the sleeve 13 from sliding out of the opening 16.
Die Teleskopstange 2 wird zum einen im Abschnitt 11 geführt, zum anderen durch das Führungsteil 3, welches in das in dem Führungsrohr 1 eingeschobene Ende eingesteckt und reibschlüssig verbunden ist. Gegen unbeabsichtigtes Herausziehen der Teleskopstange 2 aus dem Führungsrohr 1 ist das Führungsteil 3 mit einer Schulter 18 versehen, welche mit dem Anschlag 12 zusammenwirkt. Die Schulter 18 entsteht durch die unterschiedliche Dimension der Innenkontur 5 des Führungsrohrs 1 gegenüber der Außenkontur 4 des Teleskoprohrs 2.The telescopic rod 2 is guided on the one hand in section 11, on the other hand through the guide part 3, which is inserted into the end inserted into the guide tube 1 and connected by friction. To prevent the telescopic rod 2 from being pulled out of the guide tube 1 unintentionally, the guide part 3 is provided with a shoulder 18 which interacts with the stop 12. The shoulder 18 is created by the different dimensions of the inner contour 5 of the guide tube 1 compared to the outer contour 4 of the telescopic tube 2.
Der in Fig. 2 dargestellte Schnitt verdeutlicht die polygonale Außen- und Innenkontur des Stiels, die sich im Teleskoprohr 2, dem zweiten Abschnitt 11 der Arretiervorrichtung 9 sowie der Hülse 13 widerspiegelt. Gestrichelt darge- stellt ist die Innenkontur 5 des Führungsrohrs 1. Die Kugel 17 liegt in einer Einbuchtung 8 des Teleskoprohrs 2 und in der Öffnung 16 im zweiten Abschnitt 11. Zur besseren Greifbarkeit der Hülse 13 ist ein Vorsprung 19 vorgesehen, der sich zumindest teilweise über den Umfang der Hülse 13 er- streckt und im Bereich der Kugel 17 seinen größten Abstand von der Hülse 13 aufweist.The section shown in Fig. 2 illustrates the polygonal outer and inner contour of the stem, which is reflected in the telescopic tube 2, the second section 11 of the locking device 9 and the sleeve 13. The inner contour 5 of the guide tube 1 is shown in dashed lines. The ball 17 lies in an indentation 8 of the telescopic tube 2 and in the opening 16 in the second section 11 the circumference of the sleeve 13 stretches and has its greatest distance from the sleeve 13 in the region of the ball 17.
In Fig. 3 ist die Arretiervorrichtung 9 in einem geöffneten Zustand dargestellt, d.h. die Arretierung ist gelöst, das Teleskoprohr 2 läßt sich in dem Führungsrohr 1 verschieben. Dazu ist die Hülse 13 bis zu dem Anschlag 15 von dem Führungsohr 1 weg axial verschoben worden, wodurch die Kugel 17 aus der Einbuchtung 8 heraustreten kann. Die Hülse 13 weist hierzu einen die Kugel 17 aufnehmenden Bereich 20 auf, der die Kugel 17 gegen Herausfallen sichert. Dabei übt der Bereich 20 eine Federkraft auf die Kugel 17 aus, so daß diese beim Verschieben der Teleskopstange 2 in die Ausbuchtungen 8 gleitet und so der Benutzer die verschiedenen Ar- retierpositionen auf einfache Weise erkennt.In Fig. 3 the locking device 9 is shown in an open state, i.e. the lock is released, the telescopic tube 2 can be moved in the guide tube 1. For this purpose, the sleeve 13 has been axially displaced away from the guide tube 1 up to the stop 15, as a result of which the ball 17 can emerge from the indentation 8. For this purpose, the sleeve 13 has a region 20 which receives the ball 17 and which secures the ball 17 against falling out. The area 20 exerts a spring force on the ball 17 so that it slides into the bulges 8 when the telescopic rod 2 is displaced and the user can easily recognize the various locking positions.
In Fig. 4 ist ein Stielsegment 21 aus Metall eines aus mehreren Stielsegmenten bestehenden Stiels dargestellt. Das Stielsegment 21 weist an seinem einen Ende ein Kupplungse- lement 22 aus Kunststoff auf. Dieses Kupplungselement 22 ist in das Stielsegment 21 eingeschoben und unlösbar mit diesem verbunden, beispielsweise durch Kleben. Ein aus dem Stielsegment herausragender Bereich des hohlen Kupplungsteils 22 ist mit einem Rastknopf 23 versehen, der gegen ei- ne Feder 24 in das Kupplungsteil 22 gedrückt werden kann. An dem anderen Ende des Stielsegments ist dieses mit einer dem Rastknopf 23 entsprechenden Öffnung 24 versehen, wobei die Öffnung 24 so zum Ende des Stielsegments 21 beabstandet ist, daß der herausragende Teil des Kupplungsstückes 22 mit dem Rastknopf 23 aufgenommen werden kann und der Rastknopf 23 in die Öffnung 24 eingreifen kann.4 shows a stem segment 21 made of metal from a stem consisting of a plurality of stem segments. The stem segment 21 has a plastic coupling element 22 at one end. This coupling element 22 is inserted into the stem segment 21 and permanently connected to it, for example by gluing. A region of the hollow coupling part 22 which protrudes from the stem segment is provided with a latching button 23 which can be pressed into the coupling part 22 against a spring 24. At the other end of the stem segment this is provided with an opening 24 corresponding to the locking button 23, the opening 24 being spaced from the end of the stem segment 21 such that the protruding part of the coupling piece 22 can be received with the locking button 23 and the locking button 23 in the opening 24 can engage.
Durch aneinanderfügen mehrerer Stielsegmente 21 kann ein Stiel in verschiedenen Längen zusammengebaut werden. Fig. 5 zeigt eine Stielkappe 26 aus Kunststoff zum Aufstekken auf ein dem Benutzer zugewandtes Ende 31 eines des Stiels. Die Stielkappe 26 ist gegenüber dem Stielende 31 längsverschieblich aufgesteckt und in verschiedenen, durch Öffnungen 27 vorgegebenen Positionen mittels einer aus Rastknopf 28 und Feder 29 bestehenden Rastvorrichtung an diesem arretierbar. Die Rastvorrichtung 28, 29 ist im Stielende 31 untergebracht, wobei das Stielende 31 eine Öffnung aufweist, durch welche der Rastknopf hindurchragt. Die In- nenkontur der Stielkappe 26 entspricht der Außenkontur des Stielendes 31 und ist daher polygonal. Der Kraftschluß der Stielkappe 26 mit dem Stielendes 31 wird beim Drehen der Stielkappe 27 durch den Formschluß hergestellt. Die Stielkappe 26 ist mit weiteren Öffnungen 30 versehen, mittels welcher das Stielende 31 beispielsweise in eine Haken eingehängt werden kann.By joining together several stem segments 21, a stem can be assembled in different lengths. Fig. 5 shows a stem cap 26 made of plastic for plugging onto an end 31 of the stem facing the user. The handle cap 26 is slidably slidable relative to the handle end 31 and can be locked in various positions predetermined by openings 27 by means of a locking device consisting of locking button 28 and spring 29. The locking device 28, 29 is accommodated in the handle end 31, the handle end 31 having an opening through which the locking button projects. The inner contour of the stem cap 26 corresponds to the outer contour of the stem end 31 and is therefore polygonal. The force fit of the stem cap 26 with the stem end 31 is produced when the stem cap 27 is rotated by the positive connection. The stem cap 26 is provided with further openings 30, by means of which the stem end 31 can be hung, for example, in a hook.
Fig. 6 zeigt die Lage der Feder 29 im Stielende 31 bei arretierter Stielkappe 26. Der Rastknopf 28 befindet sich folglich in ausgerückter Stellung. Die Feder 29 stützt sich zum einen im Bereich der stark gekrümmten Kante 7 des Stielendes 31 an der Innenwand ab, zum anderen an der Seitenfläche 6. Durch eine Öffnung in der Seitenfläche 6 und in der Stielkappe 26 ragt der Rastknopf 28 ein Stück weit her- vor. 6 shows the position of the spring 29 in the handle end 31 when the handle cap 26 is locked. The locking button 28 is consequently in the disengaged position. The spring 29 is supported on the one hand in the region of the strongly curved edge 7 of the handle end 31 on the inner wall, and on the other hand on the side surface 6. The latching button 28 protrudes a little way through an opening in the side surface 6 and in the handle cap 26. in front.
