Description

Verstellvorrichtung, insbesondere für einen Stellfuß eines Haushaltsgeräts Adjusting device, in particular for a leveling foot of a household appliance
Die Erfindung betrifft eine Verstellvorrichtung, insbesondere für einen Stellfuß eines Ge¬ genstands, bestehend aus einem in einem Stellgehäuse gelagerten axial verstellbaren Gewindeschaft oder -bolzen. Die Erfindung betrifft weiterhin ein Haushaltsgerät mit einer Verstellvorrichtung der oben genannten Art.The invention relates to an adjusting device, in particular for a leveling foot of a Ge genständen, consisting of a mounted in a control housing axially adjustable threaded shaft or bolt. The invention further relates to a household appliance with an adjusting device of the type mentioned above.
Es ist beispielsweise bei Haushaltsgeräten seit langem bekannt, diese mit Stellfüßen zu versehen, von denen wenigstens einer zur Anpassung des aufzustellenden Haushaltsge- rätes an die örtlichen Gegebenheiten in der Höhe verstellbar ist. Um die Höheneinstellung der Stellfüße für einen Benutzer zu erleichtern, ist aus dem Stand der Technik eine Viel¬ zahl an unterschiedlichen Lösungen bekannt.For example, in household appliances it has long been known to provide them with adjustable feet, at least one of which can be adjusted in height for adapting the household appliance to be installed to the local conditions. In order to facilitate the height adjustment of the adjustable feet for a user, a multitude of different solutions is known from the prior art.
Die DE 196 06 460 A1 beschreibt eine Höhenverstellvorrichtung für einen Stellfuß aus einem in einem gehäusefesten Verstellgehäuse geführten, senkrechten Gewindeschaft mit Fußteller, wobei über den Gewindeschaft eine in dem Verstellgehäuse drehbar gela¬ gerte Mutter geschraubt ist, die an ihrem Außenumfang als Schneckenrad ausgebildet ist und über eine mit einer Verstellstange verbundene, in dem Verstellgehäuse drehbar gela¬ gerte Schnecke angetrieben wird. Dabei ist der Gewindeschaft des Stellfußes im Verstell- gehäuse formschlüssig geführt. Durch die formschlüssige Führung des Gewindeschaftes des Stellfußes wird der Stellfuß bei einer Betätigung der Höhenverstellvorrichtung nicht mitgedreht. Der Formschluss wird durch eine Abflachung entlang des Gewindes bzw. we¬ nigstens eine axial verlaufende Nut erzielt, wobei die Abflachung an dem Verstellgehäuse an wenigstens einer Stelle anliegt bzw. das Verstellgehäuse in die axial verlaufende Nut eingreift. Durch die Verwendung eines Getriebes weist die beschriebene Anordnung den Nachteil auf, dass aufgrund des Getriebes ein verhältnismäßig großes Verstellgehäuse benötigt wird.DE 196 06 460 A1 describes a height adjustment device for a leveling foot out of a guided in a housing-fixed adjustment, vertical threaded shaft with foot plate, being screwed over the threaded shank in the adjustment rotatably gela¬ siege nut, which is formed on its outer circumference as a worm wheel and is driven via a connected to an adjusting rod, in the adjusting rotatably gela¬ siege worm. The threaded shank of the adjustable foot is positively guided in the adjustment housing. Due to the positive guidance of the threaded shank of the adjustable foot of the adjustable foot is not rotated when operating the height adjustment. The positive connection is achieved by a flattening along the thread or at least one axially extending groove, wherein the flattening rests against the adjusting housing at least one point or the adjusting housing engages in the axially extending groove. By using a transmission, the arrangement described has the disadvantage that due to the transmission, a relatively large adjustment is needed.
Eine ähnliche Anordnung ist in der DE 94 21 684 U1 beschrieben. Eine der DE 196 06 460 A1 ähnliche Anordnung ist weiterhin in der DE 295 12 662 U1 beschrieben, bei der die Schnecke darüber hinaus mit einer Rutschkupplung versehen ist, um Beschädigungen am Getriebe zu vermeiden.A similar arrangement is described in DE 94 21 684 U1. A DE 196 06 460 A1 similar arrangement is further described in DE 295 12 662 U1, in which the screw is also provided with a slip clutch to prevent damage to the gearbox.
Ein weiteres Haushaltsgerät mit höhenverstellbaren Stützfüßen ist aus der DE 33 36 375 C2 bekannt. Die Stützfüße bestehen aus einem im Geräteboden schraubbar gelagerten Gewindeschaft mit einem Fußteller. Weiterhin ist eine als Getriebe ausgebildete Vorrich¬ tung zum Verstellen der hinteren Geräte-Stützfüße mittels einer Stellstange von der Vor¬ derseite des Haushaltsgerätes aus vorgesehen. Der fest mit dem Gewindeschaft verbun¬ dene Fußteller ist als Schneckenrad ausgebildet, in das eine Schneckenwelle eingreift. Die Schneckenwelle ist Bestandteil der Stellstange und aus Draht durch wendeiförmiges Aufwickeln gefertigt. Die Belastbarkeit einer derartigen Konstruktion ist prinzipbedingt ge¬ ring.Another household appliance with height-adjustable support legs is known from DE 33 36 375 C2. The support feet consist of a threaded shaft mounted in a screw-down manner in the device base with a foot plate. Furthermore, a device designed as a transmission is provided for adjusting the rear appliance support feet by means of an actuating rod from the front of the household appliance. The foot plate, which is firmly connected to the threaded shank, is designed as a worm wheel into which a worm shaft engages. The worm shaft is part of the control rod and made of wire by helical winding. The load capacity of such a construction is inherently ring.
Bei dem in der DE-GM 74 35 483 beschriebenen Haushaltsgerät ist das Getriebe zur Stützfußverstellung innerhalb des Gerätegehäuses angeordnet, wozu der Stützfuß bzw. dessen verlängerter Gewindeschaft innerhalb des Gerätegehäuses formschlüssig mit ei¬ nem Schneckenrad als Teil des Getriebes verbunden ist. Mit einer zur Frontseite des Ge¬ rätes hingeführten Stelleinrichtung in Form einer Stellstange kann der Stützfuß vertikal bewegt werden. Die Stellstange trägt hierfür eine Schnecke, die mit dem Schneckenrad in Eingriff steht. Im Bereich der Maschinenfrontseite ist die Stellstange in einem Gummiele¬ ment gelagert, das in einen Durchbruch des Gehäuseblechs der Maschine eingesetzt ist. Der Stützfuß mit dem im Gehäuseboden schraubbar gelagerten Gewindeschaft ist unter¬ seitig mit einem Gummibelag versehen, wobei das bodenseitige Ende drehbar in dem Fußteller lagert. Nachteil dieser Anordnung ist, dass sämtliche zum Getriebe gehörigen Teile innerhalb des Gerätegehäuses in Bereichen angeordnet sind, die sowohl fertigungs¬ technisch als auch zu Wartungszwecken schlecht zugänglich sind, so dass sich ein derart angeordnetes Getriebe negativ auf die Kosten der Herstellung auswirkt.In the domestic appliance described in DE-GM 74 35 483 the transmission is arranged for Stützfußverstellung within the device housing, including the support leg or its extended threaded shank is positively connected within the device housing with egg nem worm wheel as part of the transmission. The support foot can be moved vertically by means of an adjusting device guided in the direction of the front of the appliance in the form of an adjusting rod. The control rod carries for this purpose a worm, which is in engagement with the worm wheel. In the area of the machine front, the control rod is mounted in a rubber element which is inserted into an opening in the housing of the machine. The support leg with the threaded shank which is screwed in the housing bottom is provided on the underside with a rubber coating, wherein the bottom end rotatably supports in the foot plate. Disadvantage of this arrangement is that all belonging to the gear parts are arranged within the device housing in areas that are both fertigungs¬ technically difficult to access and for maintenance purposes, so that such a transmission has a negative effect on the cost of manufacturing.
Aus der US 1 ,632,383 ist es schließlich bekannt, zur Höhenverstellung eines Tischbeins ein in dem Tischbein untergebrachtes Kegelradgetriebe zu verwenden.Finally, it is known from US Pat. No. 1,632,383 to use a bevel gearbox housed in the table leg for height adjustment of a table leg.
Der Erfindung liegt daher die Aufgabe zugrunde, auf einfache Art und Weise eine Höhen- verstellvorrichtung, insbesondere für einen Stellfuß eines Gegenstands, wie ein Haus- haltsgerät oder Möbel sowie auch auf anderen Gebieten, z. B. im Automobibau, zu schaf¬ fen, die bei einfachem Aufbau eine hohe Stabilität gewährleistet und kostengünstig her¬ stellbar ist.The invention is therefore based on the object in a simple manner a height adjustment device, in particular for a leveling foot of an object, such as a house or furniture as well as in other areas, such. As in automobile construction, schaf¬ fen, which ensures a high stability with a simple structure and is producible at low cost.
Es soll weiterhin ein Haushaltsgerät angegeben werden, bei dem sich zumindest einzelne Stellfüße auf möglichst einfache und kostengünstige Weise in der Höhe verstellen lassen.It should continue to be given a household appliance, in which at least individual feet can be adjusted in the simplest and most cost-effective manner in height.
Diese Aufgaben werden mit einer Verstellvorrichtung mit den Merkmalen des Anspruches 1 sowie mit einem Haushaltsgerät mit den Merkmalen des Anspruches 13 gelöst. Vorteil¬ hafte Ausgestaltungen ergeben sich jeweils aus den abhängigen Ansprüchen.These objects are achieved with an adjusting device having the features of claim 1 and with a household appliance having the features of claim 13. Advantageous embodiments emerge in each case from the dependent claims.
Erfindungsgemäß ist der Gewindeschaft oder -bolzen derart ausgestaltet, dass dieser mit einer in dem Verstellgehäuse drehbar gelagerten Schnecke in Eingriff bringbar ist, um über eine Drehbewegung der Schnecke unmittelbar eine Drehung des Gewindeschafts oder -bolzens herbeizuführen. Hierdurch ist mit Vorteil ein Getriebe geschaffen, das ge- genüber den aus dem Stand der Technik bekannten Anordnungen weniger Bauteile auf¬ weist, wodurch die Verstellvorrichtung insgesamt weniger Platz benötigt. Erzielt wird dies insbesondere dadurch, dass die Schnecke und der Gewindeschaft oder -bolzen in unmit¬ telbarem Eingriff stehen. Möglich wird dies dadurch, dass der Gewindeschaft oder - bolzen gegenüber dem Verstellgehäuse drehbar gelagert ist. Über die mit dem Gewinde- schaft oder -bolzen in Verbindung stehende Schnecke wird dann eine Drehung des Ge¬ windeschafts bewirkt, um diesen axial in die gewünschte Richtung zu verstellen.According to the invention, the threaded shank or bolt is configured in such a way that it can be brought into engagement with a worm rotatably mounted in the adjusting housing, in order to bring about a rotation of the threaded shank or bolt directly via a rotary movement of the worm. As a result, a transmission is advantageously provided which has fewer components than the arrangements known from the prior art, as a result of which the adjusting device requires less space overall. This is achieved in particular by the fact that the worm and the threaded shank or bolt are in direct engagement. This is made possible by the fact that the threaded shaft or bolt is rotatably mounted relative to the adjusting housing. The worm shaft is then rotated via the worm connected to the threaded shaft or bolt in order to adjust it axially in the desired direction.
Um eine Verstellung des Gewindeschafts oder -bolzens in dessen axialer Richtung auch von der Vorderseite eines zu verstellenden Gegenstands bewirken zu können, ist es vor- teilhaft, wenn sich gemäß einer Ausgestaltung der Erfindung die Achsen der Schnecke und des Gewindeschafts oder -bolzens in einem Winkel, bevorzugt einem 90°-Winkel, kreuzen.In order to be able to effect an adjustment of the threaded shaft or bolt in its axial direction also from the front of an object to be adjusted, it is advantageous if, according to one embodiment of the invention, the axes of the worm and of the threaded shaft or bolt are at an angle , preferably at a 90 ° angle, intersect.
Zur Herbeiführung einer Drehung des Gewindeschafts oder -bolzens durch eine Schne- cke, die mit dem Gewindeschaft oder -bolzen in unmittelbarem Eingriff steht, ist gemäß der Erfindung vorgesehen, dem Gewinde des Gewindeschafts oder -bolzens eine Ver¬ zahnung zu überlagern, um den direkten Eingriff der Schnecke in den Gewindeschaft oder -bolzen zu ermöglichen. - A -In order to bring about a rotation of the threaded shaft or bolt by a worm, which is in direct engagement with the threaded shank or bolt, it is provided according to the invention to superimpose a serration on the thread of the threaded shank or bolt in order to prevent the direct To allow engagement of the screw in the threaded shaft or bolt. - A -
Die Verzahnung kann durch eine Mehrzahl von in den Gewindeschaft oder -bolzen ein¬ gebrachte Nuten gebildet werden, die sich im Wesentlichen parallel zueinander verlau¬ fend erstrecken. Der Verzicht auf ein weiteres Schneckenrad, das bei Betätigung der Schnecke eine axiale Verstellung des Gewindeschafts oder -bolzens im Stand der Tech¬ nik bewerkstelligt, wird mit anderen Worten dadurch möglich, dass dem Gewinde des Gewindeschafts eine weitere Verzahnung überlagert wird, die derart ausgestaltet ist, dass sie an das Schneckengewinde der Schnecke angepasst ist. Bevorzugt verlaufen die Nu¬ ten dabei schraubenförmig, wobei gegenüber der Achse des Gewindeschafts oder - bolzens ein spitzer Winkel gebildet ist.The toothing can be formed by a plurality of grooves formed in the threaded shank or bolt, which grooves extend essentially parallel to one another. The omission of a further worm wheel, which accomplishes an axial adjustment of the threaded shaft or bolt in the prior Tech¬ technology when operating the screw, in other words, it is possible that the thread of the threaded shaft, a further toothing is superimposed, which is configured in that it is adapted to the worm thread of the worm. In this case, the grooves preferably run helically, an acute angle being formed with respect to the axis of the threaded shaft or bolt.
Bevorzugt übergreift das Verstellgehäuse den Gewindeschaft oder -bolzen, so dass das Gewinde des Gewindeschafts oder -bolzens in ein entsprechendes Gewinde einer Boh¬ rung des Verstellgehäuses eingreift. Anders ausgedrückt, bedeutet dies, dass das Ver¬ stellgehäuse selbst ein Gewinde aufweist, so dass der Gewindeschaft oder -bolzen mit seinem Gewinde in dieses eindrehbar ist. Das Verstellgehäuse kann auch über ein sepa- rates Bauteil, das mit diesem formschlüssig verbunden ist, aufweisen, welches dann mit einem Gewinde versehen ist, in welches der Gewindeschaft oder -bolzen eindrehbar ist. Das Verstellgehäuse kann auch durch einen Teil des zu verstellenden Gegenstands selbst gebildet sein.Preferably, the adjusting housing engages over the threaded shank or bolt, so that the thread of the threaded shaft or bolt engages in a corresponding thread of a bore of the adjusting housing. In other words, this means that the Ver¬ adjusting housing itself has a thread, so that the threaded shaft or bolt with its thread can be screwed into this. The adjusting housing can also have a separate component, which is positively connected thereto, which is then provided with a thread into which the threaded shaft or bolt can be screwed. The adjustment can also be formed by a part of the object to be adjusted itself.
Nach einer weiteren vorteilhaften Ausgestaltung ist die Schnecke einer Buchse des Ver¬ stellgehäuses drehbar gelagert. Besonders bevorzugt ist es dabei, wenn die Buchse formschlüssig lösbar im Verstellgehäuse angeordnet ist. Diese Vorgehensweise ermög¬ licht es, bei der Fertigung der Verstellvorrichtung wahlweise eine Schnecke in der Ver¬ stellvorrichtung vorzusehen oder auch nicht. Dadurch, dass der Gewindeschaft oder - bolzen drehbar in einem Gewinde der Verstellvorrichtung gelagert ist, ist es auch möglich, den Gegenstand durch unmittelbares Verdrehen des Gewindeschafts oder -bolzens zu verstellen. Eine komfortablere Verstellmöglichkeit ist dann gegeben, wenn die axiale Ver¬ schiebung des Gewindeschafts oder -bolzens mittels der dann in der Verstellvorrichtung vorgesehenen Schnecke erfolgen kann. Die bevorzugte Verstellvorrichtung mit Schnecke kann beispielsweise während der Fertigung Gegenständen einer höheren Preiskategorie vorbehalten bleiben, während Gegenstände einer unteren Preiskategorie lediglich durch direktes Verdrehen des Gewindeschafts oder -bolzens einstellbar sind, da die Schnecke bei diesen weggelassen ist. In einer weiteren zweckmäßigen Ausgestaltung ist die Schnecke 1- oder 2-gängig aus¬ gebildet. Die Wahl, mit wie viel Gängen das Gewinde der Schnecke ausgebildet wird, hängt davon ab, mit welchem Verdrehwinkel der Schnecke welcher axiale Weg des Ge¬ windeschafts oder -bolzens betätigt werden soll, bzw. welche Kräfte auf die Verzahnung auf den Gewindeschaft bzw. -bolzen einwirken dürfen, ohne dass dieser im Einsatz be- schädigt wird. Die geeignete Wahl hängt letztendlich davon ab, welcher Gegenstand mit¬ tels der erfindungsgemäßen Verstellvorrichtung verstellt werden soll.According to a further advantageous embodiment, the screw of a bushing of the adjusting housing is rotatably mounted. It is particularly preferred if the socket is arranged releasably releasably in the adjustment. This procedure makes it possible to optionally provide a screw in the adjusting device during production of the adjusting device or else not. Because the threaded shank or bolt is rotatably mounted in a thread of the adjusting device, it is also possible to adjust the object by direct rotation of the threaded shaft or bolt. A more comfortable adjustment is given when the axial Ver¬ shift of the threaded shaft or bolt can be done by means of the then provided in the adjustment screw. The preferred screw adjustment device may, for example, be reserved for articles of a higher price category during manufacture, while articles of a lower price category can only be adjusted by direct rotation of the threaded shaft or bolt since the screw is omitted therefrom. In a further expedient embodiment, the screw is formed 1 or 2-course aus¬. The choice of how many gears the thread of the screw is formed depends on which angle of rotation of the screw which axial path of the Ge threaded stem or bolt is to be actuated, or which forces on the toothing on the threaded shaft or bolt may act without this being damaged in use. The suitable choice ultimately depends on which object is to be adjusted by means of the adjusting device according to the invention.
Wahlweise kann der Gewindeschaft oder -bolzen und/oder die Schnecke aus einem Kunststoff, insbesondere mittels eines Spritzgussverfahrens, oder einem Metall gefertigt werden. Der Gewindeschaft kann vorzugsweise einteilig oder mehrteilig, insbesondere zweiteilig aus einem Rohrelement und einer Gewindestange, ausgebildet sein. Die Ver¬ wendung von Metall ermöglicht dabei besonders langlebige Verstellvorrichtungen, da auch häufige Betätigung nicht zu einem nennenswerten Verschleiß führen wird.Alternatively, the threaded shaft or bolt and / or the worm can be made of a plastic, in particular by means of an injection molding process, or a metal. The threaded shaft may preferably be formed in one or more parts, in particular in two parts, of a tubular element and a threaded rod. The use of metal in this case allows particularly long-lived adjusting devices, since frequent operation will not lead to significant wear.
Es ist weiter bevorzugt, wenn die Verstellvorrichtung eine Höhenverstellvorrichtung für einen Stellfuß eines Haushaltsgeräts, wie z. B. ein Herd, eine Waschmaschine, ein Wä¬ schetrockner oder eine Geschirrspülmaschine, darstellt und der Gewindeschaft oder - bolzen an einem bodenseitigen Ende mit einem Teller versehen ist.It is further preferred if the adjusting device is a height adjustment device for a leveling foot of a household appliance, such. As a stove, a washing machine, a Wä¬ schetrockner or a dishwasher, and the threaded shaft or bolt is provided at a bottom end with a plate.
Um zu vermeiden, dass durch eine Drehung des Gewindeschafts oder -bolzens und dem mit diesem verbundenen Teller eine Beschädigung des Untergrunds herbeigeführt wird, sind gemäß einer weiteren bevorzugten Ausgestaltung der Gewindeschaft oder -bolzen und der Teller gegeneinander verdrehbar miteinander verbunden.In order to avoid that a damage of the substrate is caused by a rotation of the threaded shaft or bolt and the plate connected thereto, according to a further preferred embodiment, the threaded shaft or bolt and the plate against each other rotatably connected to each other.
Ein erfindungsgemäßes Haushaltsgerät der oben genannten Art ist dadurch gekenn¬ zeichnet, dass dieses zumindest eine Verstellvorrichtung nach einer der oben beschrie¬ benen Ausgestaltungen aufweist.An inventive household appliance of the type mentioned above is characterized gekenn¬ characterized in that it has at least one adjusting device according to one of the above beschrie¬ surrounded embodiments.
Nach einer vorteilhaften Ausführungsform der Erfindung ist das Haushaltsgerät mit zu- mindest drei Stellfüßen ausgestattet, wobei zwei Stellfüße frontseitig an dem Haushalts¬ gerät und ein Stellfuß rückseitig an dem Haushaltsgerät angeordnet sind, und wobei der rückseitig angeordnete Stellfuß mit der Verstellvorrichtung von einer Seitenwand des Haushaltsgeräts aus in der Höhe verstellbar ist. Mit der Anordnung nur eines Stellfußes mit einer von einer Gehäuseseitenwand aus bedienbaren Verstellvorrichtung wird der Aufwand bei einem Haushaltsgerät und damit die Kosten gesenkt.According to an advantageous embodiment of the invention, the household appliance is equipped with at least three adjustable feet, wherein two adjustable feet front of the Haushalts¬ device and a leveling foot are arranged on the back of the household appliance, and wherein the rear-mounted adjustable foot with the adjustment of a side wall of the household appliance is adjustable in height. With the arrangement of only one adjustable foot with an operable from a side wall of housing adjustment of the cost of a home appliance and thus the cost is reduced.
Nach einer bevorzugten Ausführungsform der Erfindung ist der rückseitig an dem Haus¬ haltsgerät angeordnete Stellfuß etwa in der Mitte der unteren rückseitigen Gehäusekante des Haushaltsgerätes angeordnet. Durch die Anordnung des rückseitig angeordneten Stellfußes etwa in der Mitte der unteren rückseitigen Gehäusekante ist eine Auflage mit dem Grundriss eines etwa gleichschenkeligen Dreiecks, das die stabilste Auflageform einer Dreipunktauflage darstellt, geschaffen.According to a preferred embodiment of the invention, the adjusting foot arranged on the rear side of the household appliance is arranged approximately in the middle of the lower rear housing edge of the household appliance. Due to the arrangement of the rear foot arranged approximately in the middle of the lower rear housing edge is a support with the floor plan of an approximately isosceles triangle, which represents the most stable support form of a three-point support created.
Vorteilhafterweise weist zumindest die Verstellvorrichtung des rückseitig angeordneten Stellfußes die in den Gewindeschaft oder -bolzen eingreifende Schnecke auf, die über eine mit ihr in Wirkverbindung stehende und in dem Haushaltsgerät drehbar gelagerte, von der Vorderseite des Haushaltsgeräts bedienbare Verstellstange betätigbar ist.Advantageously, at least the adjusting device of the adjusting foot arranged on the rear side engages the worm engaging in the threaded shank or bolt, which can be actuated via an adjusting rod that is operatively connected to it and rotatably mounted in the household appliance and can be operated by the front of the household appliance.
Zur Erweiterung der Verstellmöglichkeit ist nach einer weiteren vorteilhaften Ausführungs¬ form der Erfindung zumindest einer der frontseitig an dem Haushaltsgerät angeordneten Stellfüße in der Höhe verstellbar.To expand the adjustment is according to a further advantageous Ausführungs¬ form of the invention, at least one of the front of the household appliance arranged adjustable feet in height adjustable.
Die Erfindung wird nachstehend anhand des in der Zeichnung dargestellten Ausführungs- beispiels erläutert. Es zeigen:The invention will be explained below with reference to the embodiment example shown in the drawing. Show it:

Fig. 4 eine weitere Darstellung des Gewindeschafts oder -bolzens, aus der die Ll- berlagerung einer Verzahnung besser ersichtlich ist. Ein Gehäuse 1 eines nicht näher erläuterten Haushaltsgeräts ist im gezeigten Ausfüh¬ rungsbeispiel mit fünf Stellfüßen 2, 10 ausgestattet, die in der Höhe verstellbar sind. Vier Stellfüße 2 sind jeweils in dem Bereich der äußeren, unteren Gehäusekanten angeordnet. Diese Stellfüße 2 sind in an sich bekannter Weise mittels ihres Gewindebolzens in ein nicht näher beschriebenes Innengewinde eines Verstellgehäuses der Verstellvorrichtung eingeschraubt und durch manuelles Ein- und/oder Herausdrehen in der Höhe verstellbar.4 shows a further illustration of the threaded shank or bolt, from which the overlay bearing of a toothing can be better seen. A housing 1 of a domestic appliance, which is not described in any more detail, is equipped with five adjustable feet 2, 10 in the embodiment shown, which are adjustable in height. Four adjustable feet 2 are each arranged in the region of the outer, lower housing edges. This leveling feet 2 are screwed in a conventional manner by means of its threaded bolt in an unspecified described internal thread of an adjustment of the adjustment and adjustable by manual input and / or unscrewing in height.
Der fünfte Stellfuß 10 ist etwa in der Mitte der unteren rückseitigen Gehäusekante ange¬ ordnet und mittels einer erfindungsgemäßen Verstellvorrichtung 20, im gezeigten Ausfüh¬ rungsbeispiel von der Frontseite 3 des Haushaltsgerätes aus, in der Höhe verstellbar. Dieser Stellfuß 10 besteht aus einem Gewindeschaft oder -bolzen, der ebenfalls in ein in dieser Figur nicht erkenntliches Innengewinde eingeschraubt ist, und einem gegenüber dem Gewindeschaft oder -bolzen drehbaren Teller 36.The fifth adjustable foot 10 is arranged approximately in the middle of the lower rear housing edge and can be adjusted in height by means of an adjusting device 20 according to the invention, in the exemplary embodiment shown, from the front side 3 of the household appliance. This adjustable foot 10 consists of a threaded shaft or bolt, which is also screwed into a not recognizable in this figure internal thread, and a relative to the threaded shaft or bolt rotatable plate 36th
Der Gewindeschaft 30 kann bei beiden Varianten in einem gehäusefesten Verstellgehäu- se 21 der Verstellvorrichtung 20 senkrecht geführt sein. Obwohl lediglich im Falle des fünften Stellfußes 1 das Verstellgehäuse 21 dargestellt ist, könnte dieses prinzipiell bei jedem der Stellfüße 2, 10 eingesetzt werden. Bei den mit dem Bezugszeichen 2 versehe¬ nen Verstellfüßen ist beispielhaft auf den Einbau einer Schnecke in das Verstellgehäuse verzichtet worden, so dass eine Höhenverstellung dieser Verstellfüße 2 lediglich durch unmittelbares Drehen des Gewindeschafts oder -bolzens oder, sofern der Teller fest mit dem Gewindeschaft verbunden ist, des Tellers, verdreht werden kann. Die Höhenverstel¬ lung des Verstellfußes 10 dagegen wird unter Verwendung einer (in Fig. 1 nicht ersichtli¬ chen) Schnecke 32 bewirkt, die über eine Stellstange 24 von der Frontseite 3 des Gerätes aus bedienbar ist.The threaded shank 30 can be guided vertically in both variants in a housing-fixed adjusting housing 21 of the adjusting device 20. Although only in the case of the fifth adjustable foot 1, the adjusting housing 21 is shown, this could in principle be used in each of the adjustable feet 2, 10. In the case of the adjusting feet denoted by the reference numeral 2, the installation of a worm into the adjusting housing has been omitted by way of example, so that a height adjustment of these adjusting feet 2 only by directly turning the threaded shaft or bolt or if the plate is firmly connected to the threaded shaft , of the plate, can be twisted. By contrast, the height adjustment of the adjusting foot 10 is effected by using a worm 32 (not shown in FIG. 1) which can be operated via an actuating rod 24 from the front side 3 of the device.
Der Aufbau der erfindungsgemäßen Verstellvorrichtung wird aus den Figuren 2 bis 4 bes¬ ser ersichtlich.The construction of the adjustment device according to the invention will be apparent from FIGS. 2 to 4.
In Fig. 2 ist in einer Schnittdarstellung eine Seitenansicht der erfindungsgemäßen Ver- Stellvorrichtung 20 dargestellt. In einem nicht näher ausgeführten Verstellgehäuse 21 , das mit einem Innengewinde 38 versehen ist, ist der Gewindeschaft 30 eingeschraubt. In un¬ mittelbarem Eingriff mit dem Gewindeschaft 30 steht die Schnecke 32, die in der Darstel¬ lung der Fig. 2 in der Draufsicht erkennbar ist. Die Achsen der Schnecke 32 und des Ge- windeschafts 30 verlaufen vorzugsweise in einem 90°-Winkel zueinander, wobei eine Schrägstellung in einem beliebigen Winke ebenso möglich ist. Die Verstellung der Schne¬ cke 32 erfolgt beispielsweise über einen Schlitz 39, in den ein Schraubendreher von einer Gehäuseseite her einführbar ist.FIG. 2 shows a sectional view of a side view of the adjusting device 20 according to the invention. In a non-detailed adjustment housing 21 which is provided with an internal thread 38, the threaded shaft 30 is screwed. In direct engagement with the threaded shank 30 is the screw 32, which can be seen in the illustration of FIG. 2 in plan view. The axes of the worm 32 and the Windeschafts 30 preferably extend at a 90 ° angle to each other, with an inclination in any angle is also possible. The adjustment of the wedge 32 takes place, for example, via a slot 39, into which a screwdriver can be inserted from one side of the housing.
Aus der Draufsicht der Fig. 3 ist besser ersichtlich, wie die mit einem Gewinde 37 verse¬ hene Schnecke 32 mit dem Gewindeschaft 30 in unmittelbarem Eingriff steht. Dem Ge¬ windeschaft 30 ist eine Verzahnung in Form von parallel zueinander verlaufender Nuten 34, die sich schraubenförmig in axialer Richtung erstrecken, überlagert. Das Gewinde 37 der Schnecke 32 und der Abstand sowie die Größe der Nuten 34 sind derart bemessen, dass eine Verdrehung des Gewindeschaftes durch Drehen der Schnecke erfolgen kann. Aus der Darstellung der Fig. 4 geht dieser Zusammenhang noch einmal in deutlicherer Weise hervor, wobei der Gewindeschaft bzw. -bolzen lediglich zu Zwecken der besseren Übersichtlichkeit halber in einem Umfangsabschnitt mit den Nuten versehen ist. In der Praxis erstrecken sich die Nuten über den gesamten Umfang des Gewindeschafts bzw. - bolzens.From the plan view of FIG. 3 it can be seen more clearly how the worm 32, which is provided with a thread 37, is in direct engagement with the threaded shank 30. The Ge threaded shank 30 is a toothing in the form of mutually parallel grooves 34 which extend helically in the axial direction, superimposed. The thread 37 of the screw 32 and the distance and the size of the grooves 34 are dimensioned such that a rotation of the threaded shaft can be done by rotating the screw. From the illustration of Fig. 4, this relationship is shown again in a clearer way, the threaded shaft or bolt is provided only for purposes of clarity in a peripheral portion with the grooves. In practice, the grooves extend over the entire circumference of the threaded shaft or bolt.
In einer weiteren, nicht dargestellten Ausführungsform kann der Gewindeschaft 30 auch zweiteilig ausgeführt sein. Der Gewindeschaft 30 besteht aus einem Rohrelement mit Gewinde 31 an der Außenseite und einem entsprechendem Teller an der Unterseite. Im zylinderförmigen Hohlraum des Rohrelements befindet sich eine vorzugsweise festste¬ hende Gewindestange. Die Rotationsbewegung wird somit vorzugsweise nur vom Rohr¬ element ausgeführt. An der Gewindestange ist das Haushaltsgerät befestigt.In another embodiment, not shown, the threaded shaft 30 may also be made in two parts. The threaded shaft 30 consists of a tubular element with thread 31 on the outside and a corresponding plate on the bottom. In the cylindrical cavity of the tubular element is a preferably festste¬ rising threaded rod. The rotational movement is thus preferably carried out only by Rohr¬ element. The appliance is attached to the threaded rod.
Um eine Höhenverstellung eines Stellfußes zu bewerkstelligen, ist die Schnecke 32 nicht unbedingt notwendig, da durch unmittelbares Drehen an dem Gewindeschaft 30 eine Ver¬ stellung in axialer Richtung möglich ist. Die Schnecke 32 wird deshalb bevorzugt in einer Buchse (nicht dargestellt) gelagert, welche das optionale Vorsehen der Verstellvorrichtung erlaubt. Dadurch kann die erfindungsgemäße Verstelleinrichtung zur Ausbildung eines „einfachen" Stellfußes 2 oder eines „komfortablen" Stellfußes 10 verwendet werden.In order to accomplish a height adjustment of a leveling foot, the worm 32 is not absolutely necessary, since an adjustment in the axial direction is possible by direct rotation on the threaded shank 30. The worm 32 is therefore preferably mounted in a bushing (not shown) which allows the optional provision of the adjustment device. As a result, the adjustment device according to the invention can be used to form a "simple" adjustable foot 2 or a "comfortable" adjustable foot 10.
Durch die Überlagerung der Verzahnung im Außengewinde des Gewindeschafts 30 ist es in vorteilhafter Weise möglich, auf das im Stand der Technik bislang verwendete Sehne- ckenrad zu verzichten, das die Drehbewegung der Schnecke in eine axiale Vorschubrich¬ tung des Gewindeschafts herbeiführt. Due to the superimposition of the toothing in the external thread of the threaded shaft 30, it is advantageously possible to adapt to the tendon hitherto used in the prior art. To dispense with ckenrad, which causes the rotational movement of the screw in an axial feed direction of the threaded shaft.
