Description

Die Erfindung betrifft eine Stütze für das Abstützen eines Bodens gegenüber einer darunter liegenden Fläche.The invention relates to a support for supporting a floor against an underlying surface.

Die Stütze besteht aus einem an der unten liegenden Fläche anliegenden Fußteil, einem davon nach oben ragenden Vertikalteil und einem daran befestigten Trageteil, welcher als Auflagefläche und/oder Verankerung des Bodens dient. Der metallische Vertikalteil besteht aus einem schlanken Schaft und einem unten liegenden, gegenüber dem Schaft verbreitert ausgeführtem Kopf. Der Kopf liegt auf einer Fläche des üblicherweise aus Kunststoff ausgeführten, noch breiteren Fußteils auf. Über jene ringförmige Fläche des Kopfes, welche sich zwischen der äußeren Umfangslinie des Kopfes und dem unteren Ende des Schaftes erstreckt, kragen Vorsprünge des Fußteils von der Umrahmung des Kopfes des Vertikalteils auf den Schaft des Vertikalteils zu. Der Schaft ist als Gewindebolzen ausgeführt. Der gesamte Vertikalteil ist um seine vertikal ausgerichtete Längsachse gegenüber dem Fußteil drehbar. Der Trageteil ist mit dem Außengewinde des Schaftes des Vertikalteils über ein Mutterngewinde in Eingriff und somit durch Drehung des Vertikalteils um dessen Achse vertikal verschiebbar.The support consists of a voltage applied to the underlying surface foot part, one of which upwardly projecting vertical part and a support member attached thereto, which serves as a support surface and / or anchoring of the soil. The metallic vertical part consists of a slender shaft and a lower, compared to the shaft widened executed head. The head rests on a surface of the usually made of plastic, even wider foot part. About that annular surface of the head, which extends between the outer peripheral line of the head and the lower end of the shaft, collar projections of the foot part of the framing of the head of the vertical part to the shaft of the vertical part to. The shaft is designed as a threaded bolt. The entire vertical part is rotatable about its vertically oriented longitudinal axis relative to the foot part. The support member is with the external thread of the shank of the vertical part via a nut thread engaged and thus by rotation of the vertical part about its axis vertically displaceable.

Stützen mit diesen Merkmalen sind aus den Schriften AT 504275 B1 , DE 2147745 A1 und DE 102004005764 A1 bekannt. Das Herstellen der Verbindung zwischen Vertikalteil der Stütze und Fußteil der Stütze erfolgt dabei, indem der Vertikalteil von oben her mit dem Kopfteil voran auf die richtige Auflagefläche am Fußteil zu gedrückt wird, wobei die zuvor erwähnten kragenden Vorsprünge elastisch zur Seite gedrückt werden, bis der Kopfteil an ihnen vorbei abgleitet. Die untere Fläche des Kopfteils ist als nach außen gewölbte Teilkugelfläche ausgebildet, wodurch dieses Abgleiten erleichtert wird. Fallweise kann das Eindrücken des Vertikalteils in die richtige Position am Fußteil auch durch Schwenken des Vertikalteils gegenüber dem Fußteil erleichtert werden. Die besagten kragenden Vorsprünge sind erforderlich um Fußteil und Vertikalteil während der Montagearbeiten aneinander zu halten. Damit der Kopf des Vertikalteils in die passende Lage am Fußteil eingedrückt werden kann, müssen diese Vorsprünge elastisch ausgeführt bzw. gehalten sein. Als nachteilig hat sich herausgestellt, dass zufolge dieser erforderlichen Elastizität der Vorsprünge der Vertikalteil der Stütze gegenüber dem Fußteil sehr leicht kippt wodurch vor allem der Montagevorgang des Bodens erschwert wird.Supports with these features are from the scriptures AT 504275 B1 . DE 2147745 A1 and DE 102004005764 A1 known. The connection between the vertical part of the support and the foot part of the support takes place by pressing the vertical part from above with the head part forward to the correct support surface on the foot part, wherein the aforementioned cantilever projections are pressed elastically to the side until the head part sliding past them. The lower surface of the head portion is formed as a convex part spherical surface, whereby this sliding is facilitated. In some cases, the impressions of the vertical part in the correct position on the foot part can also be facilitated by pivoting the vertical part relative to the foot part. The said cantilevered projections are required to hold footboard and vertical part during assembly work together. So that the head of the vertical part can be pressed into the appropriate position on the foot part, these projections must be made or held elastically. A disadvantage has been found that due to this required elasticity of the projections of the vertical part of the support with respect to the foot part very easily tilts, which especially the assembly process of the soil is difficult.

Die EP 1916356 A2 zeigt eine Stütze, welche einen Fußteil und einen Vertikalteil aufweist, wobei der Vertikalteil an seinem unteren Ende einen verbreiterten Kopf aufweist und durch eine seitliche Bewegung unter elastischer Verformung eines Teils des Fußteils am Fußteils montierbar ist, sodass er im montierten Zustand gegenüber dem Fußteil translatorisch nicht mehr bewegbar ist, wohl aber noch um seine Längsachse drehbar ist. Anders als bei den zuvor besprochenen Stützen wird der Vertikalteil am Fußteil montiert, indem er mit seinem verbreiterten, unten liegenden Kopfteil normal zu seiner vertikalen Längsachse, also seitlich in eine Umfassung am Fußteil eingeschoben wird, wobei eine Rastzunge, die an der Öffnung der Umfassung am Fußteil angeordnet ist, erst elastisch ausgebogen wird und dann wieder zurückfedert, sodass sie mit ihrer Stirnseite gegen Herausgleiten des Kopfteils des Vertikalteils aus der Umfassung am Fußteil einen Anschlag darstellt. Die Rastzunge ist Teil des Fußteils; bei ihrer bestimmungsgemäßen elastischen Verformung bewegt sich ihre als Anschlagfläche zum Vertikalteil dienende Oberfläche parallel zu sich selbst. Das führt zu zwei Nachteilen. Die besagte Oberfläche kann bei montiertem Vertikalteil nicht weichelastisch an den Vertikalteil andrücken, womit Möglichkeit Toleranzen auszugleichen verspielt werden. Der Vertikalteil kann nicht vom Fußteil weg demontiert werden, indem er einfach in die Richtung gedrückt wird, aus welcher er aus der Umfassung von Teilen des Fußteils herausgleiten kann; stattdessen ist ein jedenfalls ein separates Werkzeug erforderlich mit dem die Rastzunge niedergedrückt werden muss.The EP 1916356 A2 shows a support, which has a foot part and a vertical part, wherein the vertical part has a widened head at its lower end and is mountable by a lateral movement with elastic deformation of a part of the foot part on the foot part, so that it does not translationally in the mounted state relative to the foot part is more movable, but is still rotatable about its longitudinal axis. Unlike the supports previously discussed, the vertical part is mounted on the foot part by being inserted with its widened, lower headboard normal to its vertical longitudinal axis, ie laterally into a enclosure on the foot, wherein a latching tongue, at the opening of the enclosure on Foot part is arranged, is first bent out elastically and then springs back so that it represents with its front side against slipping out of the head portion of the vertical part of the enclosure on the footboard a stop. The latching tongue is part of the foot part; at their intended elastic deformation their serving as a stop surface to the vertical part surface moves parallel to itself. This leads to two disadvantages. The said surface can not soft elastic press on the vertical part with mounted vertical part, whereby possibility to compensate for tolerances playful. The vertical part can not be disassembled away from the foot part simply by pushing it in the direction from which it can slide out of the enclosure of parts of the foot part; instead, one is a separate tool required with the latching tongue must be depressed.

Von diesem Stand der Technik ausgehend hat sich der Erfinder die Aufgabe gestellt, eine Stütze mit den eingangs genannten Merkmalen zu schaffen, bei welcher der Vertikalteil gegenüber dem Fußteil besser richtungsstabil gehalten ist, wobei Vertikalteil und Fußteil aber dennoch einfach und werkzeuglos aneinander montierbar sein sollen und auch einfach werkzeuglos voneinander demontierbar sein sollen.Based on this state of the art, the inventor has taken on the task of creating a support with the features mentioned, in which the vertical part is held better directionally stable relative to the foot, but vertical part and foot should still be easy and without tools to mount each other and should also be easy to dismantle each other without tools.

Zum Lösen der Aufgabe wird von einer Bauweise ausgegangen bei welcher der verbreiterte Kopf des metallischen Schaftes am Fußteil aufliegt und durch Teile des Fußteils umfasst und gegen translatorische Bewegung gehalten ist und in diese Umfassung durch eine Bewegung zu bringen ist, bei der Teile des Fußteils vorübergehend elastisch verformt werden, wobei diese Bewegung wie bei der EP 1916356 A2 normal zur vertikalen Längsrichtung des Vertikalteils erfolgen soll.To solve the problem, it is assumed that a construction in which the widened head of the metallic shaft rests on the foot part and is encompassed by parts of the foot part and is held against translational movement and is to be brought into this enclosure by a movement in which parts of the foot part temporarily elastic be deformed, this movement as in the EP 1916356 A2 should take place normal to the vertical longitudinal direction of the vertical part.

In erfindungsgemäßer Weiterentwicklung der vorbekannten Bauweise wird vorgeschlagen, die Begrenzung der seitlichen Öffnung der Umfassung des Kopfes des Vertikalteils am Fußteil durch solchen einen elastisch verformbaren Teil des Fußteils vorzusehen, welcher bei montiertem Vertikalteil eine solche Oberfläche dem Vertikalteil zuwendet, welche bei bestimmungsgemäßer elastischer Verformung des elastisch verformbaren Teils vorwiegend normal zu sich selbst bewegt wird und nicht parallel zu sich selbst.In inventive development of the prior art construction is proposed to provide the limitation of the lateral opening of the enclosure of the head of the vertical part at the foot by such an elastically deformable part of the foot part, which faces such a vertical surface of the vertical part when mounted vertical part, which at the intended elastic deformation of the elastic deformable part is moved predominantly normal to itself and not parallel to itself.

Dadurch wird erreicht:This achieves:

Der bestimmungsgemäß elastisch zu verformende Teil des Fußteils kann trotz aller unvermeidbaren Maßtoleranzen von Fußteil und Vertikalteil immer mit sanftem elastischen Druck an dem zu haltenden Vertikalteil anliegen. Dadurch ist der Vertikalteil wackelfrei gehalten aber dennoch in der erforderlichen Weise um seine vertikale Achse drehbar.The intended elastic to be deformed part of the foot can always rest with gentle elastic pressure on the vertical part to be held, despite all unavoidable dimensional tolerances of foot and vertical part. As a result, the vertical part is held wobble-free but still rotatable in the required manner about its vertical axis.

Der Vertikalteil kann durch bloßes starkes Andrücken an den elastisch verformbaren Teil der Umfassung durch Teile des Fußteils werkzeug- und zerstörungsfrei aus der Umfassung und damit vom Fußteil gelöst werden.The vertical part can be solved by merely strong pressing against the elastically deformable part of the enclosure by parts of the foot part tool and nondestructive from the enclosure and thus the foot.

Durch diese Maßnahme bleibt es möglich, Fußteil und Vertikalteil durch eine einfache Schnappbewegung miteinander zu verbinden und trotzdem jene Vorsprünge des Fußteils, welche über die ringförmige Fläche des Kopfes, welche sich zwischen der äußeren Umfangslinie des Kopfes und dem unteren Ende des Schaftes erstreckt, kragen, gegen Bewegung in vertikale Richtung so steif und eng am Kopf anliegend auszuführen, dass der Vertikalteil gegen Schwenkbewegung aus der Vertikalen heraus sicher gehalten ist.By this measure, it remains possible to connect the foot part and the vertical part by a simple snap movement and yet those projections of the foot part, which over the annular surface of the head, which extends between the outer circumference of the head and the lower end of the shaft, collar, perform against movement in the vertical direction so tight and tight to the head fitting that the vertical part is held securely against pivotal movement out of the vertical.

Mit "bestimmungsgemäßer elastischer Verformung des elastisch zu verformenden Teils" ist jene elastische Verformung gemeint, die an einem die Öffnung der Umfassung des Kopfteils des Vertikalteils am Fußteil begrenzenden Teil des Fußteils zwangsweise vorgenommen werden muss, um den Kopfteil in die Umfassung hineinbewegen zu können, oder aus der Umfassung herausbewegen zu können und wobei durch konstruktive Maßnahmen gewährleistet ist, dass diese Verformbarkeit im elastischen Bereich auch gegeben ist.By "proper elastic deformation of the part to be elastically deformed" is meant that elastic deformation which must be forcibly made on a part of the foot part delimiting the opening of the skirt of the vertical part on the foot part in order to move the head part into the enclosure, or to be able to move out of the enclosure and being ensured by constructive measures that this deformability is also given in the elastic range.

In einer vorteilhaften Weiterentwicklung der Erfindung ist die seitliche Öffnung am Fußteil schmäler ist als der Durchmesser des Vertikalteils in dieser Höhe, aber durch elastische Verformung zumindest bis auf das Maß des Durchmessers des Vertikalteils in dieser Höhe aufweitbar.In an advantageous further development of the invention, the lateral opening on the foot part is narrower than the diameter of the vertical part at this height, but can be expanded by elastic deformation at least to the extent of the diameter of the vertical part at this height.

Die dargestellte erfindungsgemäße Stütze besteht aus einem Fußteil 1, einem Vertikalteil 2 und einem Trageteil 3. Der Fußteil 1 ist typischerweise als Kunststoffspritzgussteil gefertigt. Vertikalteil 2 und Trageteil 3 bestehen typischerweise aus Stahl.The illustrated support according to the invention consists of a foot part 1, a vertical part 2 and a support part 3. The foot part 1 is typically manufactured as a plastic injection molded part. Vertical part 2 and support member 3 are typically made of steel.

Der Vertikalteil 2 hat einen schlanken, vertikal ausgerichteten Schaft 2.1 und einen demgegenüber breiteren, flachen untenliegenden Kopf 2.2. Der Schaft 2.1 weist am überwiegenden Teil seiner Länge ein Außengewinde auf. Der untere Teil seines Längsbereiches ist beispielsweise sechskantförmig für den Eingriff eines Schraubschlüssels ausgeführt. An seiner oberen Stirnfläche weist er eine strukturierte Vertiefung für den Eingriff eines Schraubendrehers auf.The vertical part 2 has a slender, vertically oriented shaft 2.1 and a comparatively broader, flat, downwardly lying head 2.2. The shaft 2.1 has an external thread over most of its length. The lower part of its longitudinal region is, for example, hexagonal shaped for the engagement of a wrench. At its upper end face it has a structured recess for the engagement of a screwdriver.

Der Vertikalteil 2 ist am Fußteil 1 um die gemeinsame vertikale Achse drehbar geführt gehalten, indem der kreisrunde Kopf 2.2 des Vertikalteils 2 durch Teile des Fußteils locker umfasst ist. Diese umfassenden Teile sind eine Wand 1.1, welche die Mantelfläche des Kopfes umfasst, eine Bodenfläche 1.5, welche die Auflage für den Kopf an dessen Unterseite darstellt und drei Vorsprünge 1.2, welche von der Mantelfläche 1.1 aus auf die obere ringförmige Stirnfläche des Kopfes 2.2 ragen.The vertical part 2 is rotatably guided guided on the foot part 1 about the common vertical axis by the circular head 2.2 of the vertical part 2 is loosely encompassed by parts of the foot part. These comprehensive parts are a wall 1.1, which comprises the lateral surface of the head, a bottom surface 1.5, which represents the support for the head on its underside and three projections 1.2, which project from the lateral surface 1.1 on the upper annular end face of the head 2.2.

Die Wand 1.1, welche die Mantelfläche des Kopfes 2.2 umfasst, weist eine Öffnung 1.3 auf, deren Breite ausreichend groß ist, dass der Kopf 2.2 des Vertikalteils durch eine Bewegung des Vertikalteils normal zu seiner Achse durch diese Öffnung hindurch bewegt werden kann. Auch der Abstand zwischen den beiden Vorsprüngen 1.2, welchen beidseits der Öffnung 1.3 von der Wand 1.1 abstehen ist ausreichend groß, dass der in dieser Höhe befindliche Abschnitt des Vertikalteils durch eine Bewegung des Vertikalteils normal zu seiner Achse zwischen diesen Vorsprüngen durchgleiten kann.The wall 1.1, which comprises the lateral surface of the head 2.2, has an opening 1.3, the width of which is sufficiently large that the head 2.2 of the vertical part can be moved through this opening by a movement of the vertical part normal to its axis. Also, the distance between the two projections 1.2, which on both sides of the opening 1.3 protrude from the wall 1.1 is sufficiently large that the located at this height portion of the vertical part can slide through a movement of the vertical part normal to its axis between these projections.

Die Öffnung 1.3 in der Wand 1.1 und/oder der Abstand zwischen den Vorsprüngen 1.2 ist knapp enger als der Durchmesser des Vertikalteils in der jeweiligen Höhe bemessen, sodass zwangsweise ein bevorzugt ausschließlich elastisches Aufweiten des Fußteils in diesem Höhenbereich erfolgt, wenn der Vertikalteil durch die Öffnung 1.3 hindurch bewegt wird.The opening 1.3 in the wall 1.1 and / or the distance between the projections 1.2 is dimensioned just narrower than the diameter of the vertical part in the respective height, so forcibly one preferred Only elastic expansion of the foot in this height range takes place when the vertical part is moved through the opening 1.3 therethrough.

Die Öffnung bzw. der Abstand ist einerseits so eng zu bemessen, dass der Vertikalteil sicher gegen unerwünschte translatorische Bewegung gehalten ist, andererseits so weit, dass die einzige erwünschte translatorische Bewegung, nämlich das Einschnappen des Vertikalteils in den Fußteil, mit möglichst geringem Kraftaufwand von Hand aus durchführbar ist. Das richtige Bemessen der Weite der Öffnung bzw. des Abstandes zwischen den Vorsprüngen ist im Rahmen des fachmännischen Handelns durch Näherungsüberlegungen und Versuche einfach durchführbar. Je weichelastischer das Material des Fußteils ist, je genauer die einzelnen Abmessungen der Teile bei der Fertigung eingehalten werden und je besser gleitfähig die Materialien der Teile aneinander sind, desto einfacher und sicherer wird dieses Bemessen.The opening or the distance is on the one hand so tightly dimensioned that the vertical part is securely held against undesirable translational movement, on the other hand so far that the only desired translational movement, namely the snapping of the vertical part in the foot, with the least possible effort by hand is feasible. The correct dimensioning of the width of the opening or the distance between the projections is within the scope of professional action by approximate considerations and experiments easily feasible. The more elastic the material of the foot part is, the more accurately the individual dimensions of the parts are adhered to during production and the better lubricious the materials of the parts together, the easier and safer this dimensioning becomes.

Die Vorsprünge 1.2 brauchen in vertikaler Richtung so gut wie gar nicht verformbar bzw. verschiebbar zu sein. Damit können sie so steif ausgeführt werden, dass sie den Vertikalteil sicher und steif gegen Schwenken um horizontale Achsen halten.The projections 1.2 need in the vertical direction as well as not deformable or displaceable. They can be made so stiff that they hold the vertical part securely and rigidly against pivoting about horizontal axes.

Bevorzugt ist nur die Öffnung in der Wand 1.1 derart eng bemessen, dass sie beim Einschieben des Vertikalteils elastisch aufgeweitet werden muss. Damit können die kragenden Vorsprünge 1.2 so kurz bemessen werden, dass sich jener Längsbereich des Schaftes 2.1, welcher eine Eingriffsfläche für einen Schraubenschlüssel aufweist, beim bestimmungsgemäßen Drehen des Vertikalteils um seine vertikale Achse zwischen Vorsprüngen 1.2 sicher nicht verkantet.Preferably, only the opening in the wall 1.1 is dimensioned so narrow that it must be elastically expanded during insertion of the vertical part. Thus, the cantilevered projections 1.2 can be dimensioned so short that that longitudinal region of the shank 2.1, which has an engagement surface for a wrench, when tilted the vertical part about its vertical axis between projections 1.2 certainly not tilted.

Die erforderliche elastische Verformbarkeit von Bereichen der Wand 1.1 kann gut hergestellt werden, indem an den an die Öffnung 1.3 angrenzenden Längsbereichen der Wand 1.1, jeweils eine Öffnung 1.4 von der Unterseite des Fußteils her an die Wand 1.1 reicht, sodass diese Wand in diesem Längsbereich einen frei kragenden Biegeträger darstellt. Derartige Öffnungen 1.4 sind auch aus spritzgusstechnischen Gründen vorteilhaft um die Vorsprünge 1.2 ausbilden zu können.The required elastic deformability of areas of the wall 1.1 can be made well by extending to the adjacent to the opening 1.3 longitudinal portions of the wall 1.1, respectively an opening 1.4 from the bottom of the foot forth to the wall 1.1, so this wall in this longitudinal area a freely cantilevered Bending carrier represents. Such openings 1.4 are also advantageous for injection molding reasons to be able to form the projections 1.2.

Wie in Fig. 2 erkennbar ist die Unterseite des Kopfes 2.2 als flache, nach außen gewölbte Teilkugelschale ausgebildet. Die zugehörige Auflagefläche 1.5 des Fußteils 1 ist - abgesehen von den Unterbrechungen durch Öffnungen 1.4 - aus einer äußeren ebenen kreisringförmigen Fläche und einer inneren teilkugelflächenförmigen Mulde gebildet, deren Kugelradius kleiner ist als der Kugelradius der Unterseite des Kopfes 2.2.As in Fig. 2 recognizable the bottom of the head 2.2 is formed as a flat, outwardly curved part ball shell. The associated bearing surface 1.5 of the foot part 1 is - apart from the interruptions through openings 1.4 - formed from an outer flat annular surface and an inner teilkugelflächenförmigen trough whose ball radius is smaller than the ball radius of the underside of the head 2.2.

Indem somit der Kopf 2.2 an seiner Unterseite nur an einer ringförmigen Linie mit relativ kleinem Durchmesser am Fußteil aufliegt, entsteht an dieser Auflagefläche bei Drehung des Vertikalteils um seine vertikale Achse nur sehr wenig Reibung. Gegenüber einem Kopf 2.2 mit ebener Unterseite ist ein Kopf mit flach teilkugelschaliger Ausführung der Unterseite leichter in die Umfassung durch den Fußteil einschnappbar. Indem die untere Fläche des Kopfes 2.2 und die Auflagefläche 1.5 am Fußteil weitgehend parallel zueinander ausgerichtet sind, ist die Verbindung trotz der Linienauflage des Kopfes am Fußteil robust gegen vertikal ausgerichtete Belastungen der Stütze.By thus the head 2.2 rests on its underside only on an annular line with a relatively small diameter on the foot part, arises at this bearing surface upon rotation of the vertical part about its vertical axis only very little friction. Compared to a head 2.2 with a flat underside, a head with flat Teilkugelschaliger version of the bottom is easier snaps into the enclosure by the footboard. By the lower surface of the head 2.2 and the support surface 1.5 are aligned substantially parallel to each other on the foot, the connection is robust despite the line support of the head on the foot against vertically aligned loads on the support.
