Description

Die Erfindung betrifft einen Schwingboden für Sporthallen oder dergleichen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a vibrating floor for sports halls or the like according to the preamble of patent claim 1.

Ein Schwingboden gemäß dem Oberbegriff des Patentanspruchs 1 ist aus der DE-A-12 55 900 bekannt. Bei diesem Schwingboden wird die untere Gurtbrettlage durch Klötze aus Holz gegenüber dem Unterboden abgestützt. Zwischen der oberen Gurtbrettlage und der unteren Gurtbrettlage befinden sich Distanzstücke aus Holzstücken, derart, daß die Distanzstücke zwischen der oberen und der unteren Gurtbrettlage etwa mittig zwischen benachbarten Klötzen vorgesehen sind. Das Schwingverhalten eines solchen Schwingbodens wird im wesentlichen durch die Elastizität der oberen und unteren Gurtbrettlage bestimmt. Die Belastung der oberen Gurtbrettlage wird durch die Distanzstücke direkt auf die untere Gurtbrettlage übertragen, wobei die Steifigkeit der unteren Gurtbrettlage durch den Abstand der Lagerklötze festgelegt ist, so daß das Schwingverhalten der oberen Gurtbrettlage durch das Schwingverhalten der unteren Gurtbrettlage wesentlich mitbestimmt wird. Die Distanzelemente und/oder die Klötze tragen dagegen nicht zu dem Schwingverhalten des gesamten Schwingbodens bei.A vibrating floor according to the preamble of claim 1 is known from DE-A-12 55 900. With this vibrating floor, the lower belt board layer is supported against the sub-floor by wooden blocks. Spacers made of pieces of wood are located between the upper belt board layer and the lower belt board layer, such that the spacers between the upper and lower belt board layers are provided approximately centrally between adjacent blocks. The vibration behavior of such a vibrating floor is essentially determined by the elasticity of the upper and lower belt board layer. The load on the upper belt board layer is transferred directly to the lower belt board layer by the spacers, the rigidity of the lower belt board layer being determined by the spacing of the bearing blocks is fixed so that the vibration behavior of the upper layer of the belt board is substantially determined by the vibration behavior of the lower belt board layer. The spacer elements and / or the blocks, on the other hand, do not contribute to the vibration behavior of the entire vibrating floor.

Aus der DE-A-19 07 190 ist ein Schwingboden bekannt, bei dem zwischen der oberen und unteren Gurtbrettlage jedes Schwingträgers elastische Distanzelemente vorgesehen sind, während die untere Gurtbrettlage durch Klötze aus Holz auf dem Unterboden abgestützt ist. Die obere Gurtbrettlage weist dabei jeweils Trennfugen oberhalb jedes zweiten Distanzelements auf. Das Schwingverhalten eines solchen Schwingbodens wird hierbei zum einen bestimmt durch die elastischen Distanzelemente zwischen oberer und unterer Gurtbrettlage und zum anderen durch die Elastizität der unteren Gurtbrettlage zwischen zwei die untere Gurtbrettlage abstützenden Klötzen. Um die Elastizität der unteren Gurtbrettlage zu begrenzen, kann jeder Schwingträger zwischen benachbarten Klötzen Zusatzklötze aufweisen, die aus Holz bestehen und eine geringere Dicke haben als die benachbarten Klötze. Auf diese Weise wird erreicht, daß sich die untere Gurtbrettlage nur über einen bestimmten Bereich zwischen den beiden Klötzen durchzubiegen vermag und damit das Schwingverhalten des Schwingträgers in vorbestimmter Weise begrenzt wird.From DE-A-19 07 190 an oscillating floor is known in which elastic spacer elements are provided between the upper and lower belt board layer of each oscillating support, while the lower belt board layer is supported by wooden blocks on the sub-floor. The upper belt board layer has separating joints above every second spacer. The vibration behavior of such a vibrating floor is determined on the one hand by the elastic spacer elements between the upper and lower belt board layer and on the other hand by the elasticity of the lower belt board layer between two blocks supporting the lower belt board layer. In order to limit the elasticity of the lower belt board layer, each vibrating support can have additional blocks between adjacent blocks, which are made of wood and have a smaller thickness than the adjacent blocks. In this way it is achieved that the lower belt board layer is only able to bend over a certain area between the two blocks and thus the vibration behavior of the vibration carrier is limited in a predetermined manner.

Das DE-U-83 29 011 bezieht sich auf einen Schwingträger für Schwingböden, dessen untere Gurtbrettlage durch elastische Klötze auf dem Unterboden abgestützt ist. Oberhalb jedes Klotzes befinden sich auf der unteren Gurtbrettlage Distanzelemente aus Holz. Die obere Gurtbrettlage ist so angeordnet, daß jeweils oberhalb jedes Distanzelements die obere Gurtbrettlage unterteilende Trennfugen liegen. Ein solcher Schwingträger verwendender Schwingboden weist über die Gesamtfläche des Bodens keine gleichmäßige Elastizität auf. Vielmehr weist ein solcher Schwingboden in den Bereichen, in welchen die Distanzelemente direkt über den elastischen Klötzen liegen, gegenüber dem übrigen Bereich des Schwingbodens prägnant harte Federeigenschaften auf, d.h. der Schwingboden ist durch über seine gesamte Fläche verteilt ausgebildete Punkte mit besonders harter Federeigenschaft charakterisiert. Dieser Schwingboden hat ferner den Nachteil, daß die obere Gurtbrettlage jeweils oberhalb der Distanzelemente mit Trennfugen zu versehen ist, was zur Vermeidung einer Übertragung von Schwingungen im Nachbarbereich des Bodens erforderlich ist und mit hohem Arbeitsaufwand verbunden ist.DE-U-83 29 011 relates to an oscillating support for oscillating floors, the lower belt board layer of which is supported by elastic blocks on the sub-floor. Above each block there are spacer elements made of wood on the lower layer of the belt board. The upper belt board layer is arranged in such a way that separating joints dividing the upper belt board layer lie above each spacer element. A vibrating floor using such a vibrating support has none over the total area of the floor uniform elasticity. Rather, in the areas in which the spacer elements lie directly above the elastic blocks, such a vibrating floor has strikingly hard spring properties compared to the remaining area of the vibrating floor, ie the vibrating floor is characterized by points with a particularly hard spring property which are formed over its entire surface. This vibrating floor also has the disadvantage that the upper belt board layer is to be provided with separating joints above the spacer elements, which is necessary to avoid the transmission of vibrations in the adjacent area of the floor and is associated with a great deal of work.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, einen Schwingboden zu schaffen, der über den gesamten Bodenbereich ein gleichmäßiges Schwingverhalten aufzeigt und insbesondere keine punktuellen Bereiche mit wesentlich geringeren Federeigenschaften hat.In contrast, the invention is based on the object of creating a vibrating floor which exhibits a uniform vibration behavior over the entire floor area and in particular has no selective areas with significantly lower spring properties.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.This object is achieved by the features of the characterizing part of patent claim 1.

Weitere Ausgestaltungen des Schwingbodens ergeben sich aus den Unteransprüchen.Further designs of the oscillating floor result from the subclaims.

Die Entwicklung von Schwingböden hat sich gemäß dem aufgezeigten Stand der Technik derart entwickelt, daß zuerst die Schwingeigenschaft durch die Elastizität der oberen und/unteren Gurtbrettlage allein festgelegt wurde. Es hat sich dann gezeigt, daß eine Verbesserung des Schwingverhaltens erreichbar ist, wenn die Distanzelemente zwischen oberer und unterer Gurtbrettlage aus elastischem Material hergestellt werden und zudem eine Trennung der oberen Gurtbrettlage vorgenommen wird, um einen Übertragung von Schwingungen in die umgebenden Bereiche zu vermeiden.The development of vibrating floors has developed in accordance with the prior art shown in such a way that first the vibrating property was determined solely by the elasticity of the upper and / or lower belt board layer. It has then been shown that an improvement in the vibration behavior can be achieved if the spacer elements between the upper and lower belt board layer are made of elastic material and in addition a separation of the upper belt board layer is carried out in order to avoid the transmission of vibrations into the surrounding areas.

Schließlich wurde nach dem DE-U-83 29 011 vorgesehen, die Klötze aus elastischem Material herzustellen, während gegenüber der DE-A-19 07 190 Klötze aus Holz benutzt wurden, wodurch bei Gurtbrettlagen, die im Bereich der Distanzelemente Trennfugen aufweisen, das Schwingverhalten des durch solche Schwingträger gebildeten Schwingbodens als optimiert angesehen wurde. Überraschenderweise wurde nunmehr festgestellt, daß gemäß vorliegender Erfindung der Einsatz elastischen Materials sowohl für die Distanzelemente als auch für die Klötze mit der Maßgabe zu einem über den gesamten Bodenbereich hinweg gleichmäßigen Schwingverhalten führt, wenn im Gegensatz zu der DE-A-19 07 190 und dem DE-U-83 29 011 die Distanzelemente und die die untere Gurtbrettlage lagernden Klötze nicht in vertikal übereinander liegender Anordnung vorgesehen sind, sondern in seitlicher Richtung zueinander versetzt sind. Bei einem solchen Schwingboden treten die beim Stand der Technik gemäß der DE-A-19 07 190 und
DE-U-83 29 011 auftretenden "Punkte" äußerst harter Federeigenschaft im Bereich der übereinander liegend vorgesehenen Distanzelemente und Klötze nicht auf, vielmehr wird die Nachgiebigkeit bzw. Elastizität des Schwingbodens gegenüber diesem Stand der Technik über den gesamten Bereich des Schwingbodens hinweg vergleichmäßigt .Finally, according to DE-U-83 29 011, the blocks were made of elastic material, while compared to DE-A-19 07 190 blocks of wood were used, which caused the vibration behavior in the case of belt board layers which had separating joints in the area of the spacer elements of the vibrating base formed by such vibrating supports was regarded as optimized. Surprisingly, it has now been found that, according to the present invention, the use of elastic material both for the spacer elements and for the blocks leads to a vibration behavior which is uniform over the entire floor area, if in contrast to DE-A-19 07 190 and the DE-U-83 29 011 the spacer elements and the blocks supporting the lower belt board layer are not provided in a vertically superimposed arrangement but are offset in the lateral direction to one another. In such a vibrating floor occur in the prior art according to DE-A-19 07 190 and
DE-U-83 29 011 "points" of extremely hard spring properties in the area of the spacer elements and blocks provided one above the other, rather the resilience or elasticity of the vibrating floor compared to this prior art is evened out over the entire area of the vibrating floor.

Die überraschende Wirkung des erfindungsgemäßen Schwingbodens ergibt sich damit nicht durch die in letzter Zeit angestrebte Anordnung von übereinander liegenden Distanzelementen und Klötzen, sondern ausgehend von dem Schwingboden gemäß der DE-A-12 55 900 durch den Ersatz der dort verwendeten Klötze und Distanzelemente aus Holz durch Distanzelemente und Klötze aus elastischem Material. Die Lösung gemäß vorliegender Erfindung entspricht damit nicht der Entwicklung, wie sie durch die DE-A-12 55 900, die DE-A-19 07 190 und das DE-GM 83 29 011 fortgeführt wurde, sondern liefert eine Konstruktion, die gerade gegensätzlich ist zu Schwingböden gemäß der DE-A-19 07 190 und dem DE-U-83 29 011.The surprising effect of the oscillating floor according to the invention thus does not result from the arrangement of spacer elements and blocks lying one above the other, which has been sought recently, but rather from the oscillating floor according to DE-A-12 55 900 by replacing the blocks and spacer elements made of wood used there Spacers and blocks made of elastic material. The solution according to the present invention therefore does not correspond to the development as it was continued by DE-A-12 55 900, DE-A-19 07 190 and DE-GM 83 29 011, but rather provides a construction which is just opposite is according to the DE-A-19 07 190 and DE-U-83 29 011.

Ein weiterer Vorteil der Erfindung ergtibt sich gemäß einer bevorzugten Ausführungsform dadurch, daß die Stoßstellen zwischen oberer und unterer Gurtbrettlage symmetrisch ausgebildet sind, d.h. daß die Stoßstelle der oberen Gurtbrettlage seitlich versetzt zur Stoßstelle der unteren Gurtbrettlage vorgesehen ist und damit eine Überlappung zwischen der oberen und unteren Gurtbrettlage geschaffen wird.According to a preferred embodiment, a further advantage of the invention results from the fact that the joints between the upper and lower belt board layer are symmetrical, i.e. that the joint of the upper belt board layer is laterally offset from the joint of the lower belt board layer and thus an overlap between the upper and lower belt board layer is created.

Soll der erfindungsgemäße Schwingboden auch als Allzweckboden verwendet werden, z.B. für Ausstellungszwecke usw., ist es vorteilhaft, wenn zwischen den die untere Gurtbrettlage abstützenden Klötzen mittige Zusatzklötze vorgesehen werden, deren Stärke kleiner ist als die Stärke der Klötze. Auf diese Weise wird die Durchbiegung der unteren Gurtbrettlage zwischen den Klötzen begrenzt. Bei einem Schwingboden bzw. Allzweckboden mit einem Schwingträger der vorstehend beschriebenen Art sind die beiden Gurtbrettlagen gegenüber einer starken Belastung abgesichert, während für einen reinen Sport- oder Turnhallenboden die Zusatzklötze vorteilhafterweise weggelassen werden, um eine höhere Elastizität des Schwingbodens sicherzustellen.If the vibrating floor according to the invention is also to be used as a general-purpose floor, e.g. for exhibition purposes etc., it is advantageous if central additional blocks are provided between the blocks supporting the lower belt board layer, the thickness of which is smaller than the thickness of the blocks. In this way, the deflection of the lower belt board layer between the blocks is limited. In the case of an oscillating floor or all-purpose floor with an oscillating support of the type described above, the two belt board layers are secured against heavy loads, while for a pure sports or gym floor the additional blocks are advantageously omitted in order to ensure a higher elasticity of the oscillating floor.

Mit dem vorstehend beschriebenen Aufbau eines Schwingbodens kann die obere Gurtbrettlage eine geringere Stärke haben als die untere Gurtbrettlage. Dies hat zum Vorteil, daß der Schwingboden eine höhere Ansprechempfingdlichkeit hat gegenüber geringeren Belastungen, z.B. gegenüber dem Gewicht von Kindern oder Jugendlichen, während bekannte Schwingböden eine Ansprechempfindlichkeit haben, die auf höhere Belastungen, nämlich das Gewicht von erwachsenen Personen, abgestellt ist.With the above-described structure of an oscillating floor, the upper layer of the belt board can have a lower thickness than the lower layer of the belt board. This has the advantage that the vibrating floor has a higher sensitivity to lower loads, e.g. to the weight of children or adolescents, while known swing floors have a sensitivity that is geared to higher loads, namely the weight of adults.

Ein wesentlicher Vorteil des erfindungsgemäßen Schwingbodens ist auch darin zu sehen, daß die teilweise beim Stand der Technik erforderliche Trennung der oberen Gurtbrettlagen durch die Vornahme von Trennfugen entfällt und damit der Arbeitsaufwand verringert wird.A major advantage of the vibrating floor according to the invention can also be seen in the fact that some of the prior art the necessary separation of the upper layers of the seat belt by making separation joints is eliminated and the workload is reduced.

Die Erfindung schafft damit einen Schwingboden, insbesondere einen Sportboden für Turnhallen oder dergleichen, der sich durch eine bereits bei geringeren Belastungen bemerkbar machende Federeigenschaft auszeichnet.The invention thus creates an oscillating floor, in particular a sports floor for gyms or the like, which is characterized by a spring characteristic that is noticeable even at lower loads.

Im folgenden wird eine bevorzugte Ausführungsform des erfindungsgemäßen Schwingbodens anhand von Fig. 1 erläutert.A preferred embodiment of the vibrating floor according to the invention is explained below with reference to FIG. 1.

Auf einem Unter- oder Rohboden 1 befinden sich eine Mehrzahl von im wesentlichen parallel zueinander angeordneten und zueinander beabstandeten Schwingträgern 2a, 2b usw. Jeder Schwingträger 2a, 2b ist durch Klötze 4a, 4b usw. bzw. 5a, 5b usw. gegenüber dem Unterboden 1 abgestützt. Jeder Schwingträger besteht aus einer oberen Gurtbrettlage 7 und einer unteren Gurtbrettlage 8, zwischen welchen zueinander beabstandete Distanzelemente 9a, 9b usw. vorgesehen sind. Auf den Schwingträgern 2a, 2b usw. sind in einer zur Richtung der Schwingträger 2a, 2b etwa senkrechten Lage Bretter 10 vorgesehen, die einen Blindboden bilden. Auf den den Blindboden festlegenden Brettern 10 ist gemäß der dargestellten Ausführungsform eine Lastverteilungsschicht 11 vorgesehen, z.B. in Form von Span- oder Sperrholzplattenplatten, auf welchen ein Bodenbelag 12, z.B. in Form einer PVC-Schicht, angeordnet ist. Zwischen dem Blindboden 10 und den Spanplatten 11 kann eine Folie vorgesehen sein, die als Schutz gegen ein Durchdringen von Feuchtigkeit dient. Die den Blindboden 10 ergebenden Bretter und die Spanplatten 11 mit der Verschleißschicht 12 ergeben einen Bodenaufbau, der gegebenenfalls abgeändert werden kann, ohne daß die nachstehend beschriebene Funktion der Schwingträger für den gesamten Schwingboden verändert wird.A plurality of vibration carriers 2a, 2b, which are arranged essentially parallel to one another and spaced apart from one another, are located on a sub or raw floor 1. Each vibration carrier 2a, 2b is supported by blocks 4a, 4b etc. or 5a, 5b etc. relative to the underbody 1. Each oscillation carrier consists of an upper belt board layer 7 and a lower belt board layer 8, between which spaced-apart spacer elements 9a, 9b etc. are provided. Planks 10 are provided on the vibrating beams 2a, 2b etc. in a position approximately perpendicular to the direction of the vibrating beams 2a, 2b, which form a blind floor. According to the embodiment shown, a load distribution layer 11 is provided on the boards 10 defining the blind floor, for example in the form of chipboard or plywood board, on which a floor covering 12, for example in the form of a PVC layer, is arranged. A film can be provided between the blind base 10 and the chipboard 11, which serves as protection against moisture penetration. The boards which result in the blind floor 10 and the chipboard 11 with the wear layer 12 result in a floor structure which can be modified, if necessary, without changing the function of the vibrating carrier described below for the entire vibrating floor.

Bei dem in Fig. 1 gezeigten Ausführungsbeispiel sind die Klötze 4a, 4b mit einem Abstand Mitte-Mitte zu 50 cm zueinander vorgesehen, während die Distanzelemente 9a, 9b jeweils zwischen oberer und unterer Gurtbrettlage 7, 8 etwa mittig zwischen und oberhalb der Klötze 4a, 4b usw. vorgesehen sind. Dadurch wird erreicht, daß in Längsrichtung jedes Schwingträgers 2a, 2b gesehen ein Klotz 4a, das Distanzelement 9a, ein Klotz 4b usw. in dieser Reihenfolge hintereinander liegend angeordnet sind. Eine auf die obere Gurtbrettlage wirkende Belastung wirkt damit vorerst auf das oder die Distanzelemente 9a, 9b und die Belastung wird auf die untere Gurtbrettlage 8 übertragen. Die Distanzelemente 9a, 9b, die gemäß der Erfindung aus elastischem Material bestehen, haben eine dämpfende Charakteristik. Damit wird nur ein Teil, jedoch der überwiegende Teil der auf die obere Gurtbrettlage 7 wirkenden Belastung über die Distanzelemente 9a, 9b auf die untere Gurtbrettlage 8 übertragen. Die untere Gurtbrettlage 8 ist gleichfalls durch Klötze 4a, 4b aus elastischem Material abgestützt, wodurch die Klötze 4a, 4b ebenfalls das Schwingverhalten des betreffenden Schwingträgers mitbestimmen.In the exemplary embodiment shown in FIG. 1, the blocks 4a, 4b are provided with a center-center distance of 50 cm from one another, while the spacer elements 9a, 9b each between the upper and lower belt board layers 7, 8 approximately centrally between and above the blocks 4a, 4b etc. are provided. It is thereby achieved that, seen in the longitudinal direction of each vibrating support 2a, 2b, a block 4a, the spacer element 9a, a block 4b etc. are arranged one behind the other in this order. A load acting on the upper belt board layer thus initially acts on the spacer element (s) 9a, 9b and the load is transmitted to the lower belt board layer 8. The spacer elements 9a, 9b, which according to the invention consist of elastic material, have a damping characteristic. This means that only a part, but the predominant part, of the load acting on the upper belt board ply 7 is applied to the spacer elements 9a, 9b transfer lower belt board layer 8. The lower belt board ply 8 is also supported by blocks 4a, 4b made of elastic material, whereby the blocks 4a, 4b also determine the vibration behavior of the vibration carrier in question.

Da die Klötze und Distanzelemente in zueinander abwechselnder Weise in Längsrichtung der Schwingträger vorgesehen sind, d.h. die Distanzelemente 9a, 9b jeweils seitlich gegenüber den Klötzen 4a, 4b versetzt vorgesehen sind, ergibt sich eine Vergleichmäßigung hinsichtlich des Schwingverhaltens jedes einzelnen Schwingträgers im Gegensatz zu einem Schwingträger, bei dem entsprechend der DE-A-19 07 190 bzw. dem DE-U-83 29 011 die Distanzelemente direkt oberhalb der Klötze vorgesehen sind.Since the blocks and spacers are provided in an alternating manner in the longitudinal direction of the vibrating beams, i.e. the spacer elements 9a, 9b are each laterally offset with respect to the blocks 4a, 4b, there is an equalization with regard to the vibration behavior of each individual vibration carrier in contrast to a vibration carrier in which according to DE-A-19 07 190 and DE-U -83 29 011 the spacer elements are provided directly above the blocks.

Gemäß vorstehender Ausführungsform sind bei dem erfindungsgemäßen Schwingboden vorzugsweise die Distanzelemente 9a, 9b so angeordnet, daß jeweils ein Distanzelement bei seitlicher Betrachtung des Schwingträgers etwa mittig oberhalb zweier Klötze 4a, 4b usw. angeordnet ist. Gemäß einer weiteren Abwandlung des Schwingbodens können oberhalb zweier benachbarter Klötze 4a, 4b zwei oder mehrere Distanzelemente 9a, 9b vorgesehen sein, die ihrerseits zueinander Abstand einhalten. Die etwa mittige Anordnung eines Distanzelementes oberhalb zweier benachbarter Klötze 4a, 4b wird aber bevorzugt.According to the above embodiment, the spacer elements 9a, 9b are preferably arranged in the oscillating floor according to the invention in such a way that a spacer element is arranged approximately centrally above two blocks 4a, 4b etc. when the oscillating support is viewed from the side. According to a further modification of the vibrating floor, two or more spacer elements 9a, 9b can be provided above two adjacent blocks 4a, 4b, which in turn maintain a distance from one another. However, the approximately central arrangement of a spacer element above two adjacent blocks 4a, 4b is preferred.

Weiter wesentlich ist gemäß vorliegender Erfindung, daß sowohl die obere als auch die untere Gurtbrettlage 7, 8 durchgehend verlaufen, d.h. keine Trennfugen weder im Bereich der Distanzelemente 9a, 9b, noch im Bereich der Klötze 4a, 4b erwünscht sind.It is further essential according to the present invention that both the upper and the lower belt board layer 7, 8 run continuously, i.e. no joints are desired neither in the area of the spacer elements 9a, 9b, nor in the area of the blocks 4a, 4b.

Gemäß einer bevorzugten Ausführungsform des erfindungsgemäßen Schwingbodens hat die obere Gurtbrettlage 7 die Abmessung 16, 5 x 95 x 3500 mm, die untere Gurtbrettlage 8 die Abmessung 20,5 X 95 X 3500mm (Stärke-Breite-Länge). Die Distanzelemente 9a, 9b haben die Abmessung 60 x 100 x 5 mm, während die Klötze 4a, 4b mit 60 x 100 x 14 mm bemessen sind.According to a preferred embodiment of the vibrating floor according to the invention, the upper belt board layer 7 has the dimensions 16.5 × 95 × 3500 mm, the lower belt board layer 8 has the dimensions 20.5 × 95 × 3500 mm (thickness-width-length). The spacer elements 9a, 9b have the dimensions 60 x 100 x 5 mm, while the blocks 4a, 4b are dimensioned with 60 x 100 x 14 mm.

Die Distanzelemente 9a, 9b usw. des erfindungsgemäßen Schwingbodens haben vorzugsweise eine gegenüber der Stärke der Klötze 4a, 4b geringere Stärke, wodurch sichergestellt ist, daß eine zu starke Durchbiegung der oberen Gurtbrettlage 7 durch die Berührung mit der unteren Gurtbrettlage 8 verhindert wird. Sowohl die Distanzelemente 9a, 9b als auch die Klötze 4a, 4b haben gemäß einer weiteren Ausführungsform vorzugsweise eine größere Breite im Vergleich zur Breite der Gurtbrettlagen, so daß eine volle Abstützung der Gurtbrettlagen auf den Distanzelementen 9a, 9b und/oder den Klötzen 4a, 4b sichergestellt ist.The spacer elements 9a, 9b, etc. of the vibrating floor according to the invention preferably have a thickness that is less than the thickness of the blocks 4a, 4b, which ensures that excessive deflection of the upper belt board layer 7 is prevented by contact with the lower belt board layer 8. According to a further embodiment, both the spacer elements 9a, 9b and the blocks 4a, 4b preferably have a larger width than the width of the belt board layers, so that the belt board layers are fully supported on the spacer elements 9a, 9b and / or the blocks 4a, 4b is ensured.

Die obere und untere Gurtbrettlage 7, 8 sind, wie Fig. 2 zeigt, in einer zueinander überlappenden Weise vorgesehen. Dies bedeutet, daß die Stoßstellen der oberen Gurtbrettlage 7 gegenüber den Stoßstellen der unteren Gurtbrettlage 8 seitlich versetzt liegen. Aus Fig. 2 ist ersichtlich, daß die Stoßstelle 13 der oberen Gurtbrettlage 7 im Bereich eines der Distanzelemente 9a, 9b usw. liegt, während eine Stoßstelle 14 der unteren Gurtbrettlage 8 im Bereich des daneben befindlichen Klotzes 4a vorgesehen ist. Bei einem Abstand von 50 cm zwischen Mitte des Klötzes 4a und Mitte des Klotzes 4b bedeutet dies, daß die Stoßstellen 13, 14 etwa um einen halben Abstand zwischen benachbarten Klötzen 4a, 4b zueinander versetzt sind.The upper and lower belt board ply 7, 8 are provided in an overlapping manner as shown in FIG. 2. This means that the joints of the upper belt board layer 7 are laterally offset from the joints of the lower belt board layer 8. From Fig. 2 it can be seen that the joint 13 of the upper belt board layer 7 is in the area of one of the spacers 9a, 9b etc., while a joint 14 of the lower belt board layer 8 is provided in the area of the block 4a located next to it. At a distance of 50 cm between the center of the block 4a and the center of the block 4b, this means that the joints 13, 14 are offset by approximately half a distance between adjacent blocks 4a, 4b.

Es hat sich gezeigt, daß die Verwendung von Distanzelementen 9a, 9b und die Verwendung von Klötzen 4a, 4b in Form von elastischem Material überraschenderweise zu einem sehr guten Schwingverhalten des gesamten Schwingbodens führen, wobei durch die Vermeidung von vertikal übereinander angeordneten Klötzen 4a usw. und Distanzelementen 9a usw. ein gleichmäßiges Schwingverhalten bzw. eine gleichmäßige Elastizität des gesamten Schwingbodens gewährleistet ist und keine punktuellen Bereiche mit äußerst hartem Federvermögen auftreten. Die Stärke der Distanzelemente 9a usw. beträgt bei den dargestellten Ausführungsformen vorteilhafterweise 30 % oder 35 bis 36 % gegenüber der Stärke der Klötze 4a usw.It has been shown that the use of spacer elements 9a, 9b and the use of blocks 4a, 4b in the form of elastic material surprisingly lead to very good vibration behavior of the entire vibrating floor, with the avoidance of blocks 4a, etc. arranged vertically one above the other Spacers 9a etc. ensures a uniform vibration behavior or a uniform elasticity of the entire vibrating floor and there are no isolated areas with extremely hard resilience. The thickness of the spacer elements 9a etc. in the illustrated embodiments is advantageously 30% or 35 to 36% compared to the thickness of the blocks 4a etc.

Der erfindungsgemäße Schwingboden läßt sich mittels einer geringfügigen Abwandlung auch als Allzweckboden verwenden, der höheren Belastungen aussetzbar ist. Gemäß dieser Abwandlung des erfindungsgemäßen Schwingbodens sind zusätzliche Klötze 20a, 20b aus elastischem Material vorgesehen, die etwa mittig zwischen z.B. den Klötzen 4a, 4b eingesetzt werden. Die Zusatzklötze haben eine geringere Stärke als die Klötze 4a, 4b, vorzugsweise etwa die halbe Stärke gegenüber den Klötzen 4a, 4b. Diese Zusatzklötze 20a, 20b dienen der Begrenzung der Durchbiegung der unteren Gurtbrettlage 8.The vibrating floor according to the invention can also be used by means of a slight modification as an all-purpose floor which can be exposed to higher loads. According to this modification of the vibrating floor according to the invention, additional blocks 20a, 20b made of elastic material are provided, which are located approximately in the middle between e.g. the blocks 4a, 4b are used. The additional blocks have a smaller thickness than the blocks 4a, 4b, preferably approximately half the thickness compared to the blocks 4a, 4b. These additional blocks 20a, 20b serve to limit the deflection of the lower belt board layer 8.

Die Distanzelemente 9a, 9b und/oder die Klötze 4a,4b und/oder die Zusatzklötze 20a, 20b können mit den zugehörigen Gurtbrettlagen fest verbunden sein, beispielsweise durch Verkleben oder Verschrauben.The spacer elements 9a, 9b and / or the blocks 4a, 4b and / or the additional blocks 20a, 20b can be firmly connected to the associated belt board layers, for example by gluing or screwing.

Als elastische Materialien für die Klötze 4a, 4b und/oder die Distanzelemente 9a, 9b findet vorzugsweise Anwendung Polyurethanschaum oder kunststoffgebundene Gummifasern mit einer Rohdichte von beispielsweise ~ 500 kg/m³ und einem Druckverformungsmodul von beispielsweise ~ 0,50 N/mm², wodurch ein hoher Elastizitätsgrad und ein gutes Rückstellvermögen beim Sportboden erreicht wird.As elastic materials for the blocks 4a, 4b and / or the spacer elements 9a, 9b, use is preferably made of polyurethane foam or plastic-bonded rubber fibers with a bulk density of, for example, ~ 500 kg / m³ and a compression modulus of, for example, ~ 0.50 N / mm², which results in a high Degree of elasticity and good resilience is achieved with sports floors.

Der Zwischenraum zwischen den einzelnen Schwingträgern 2a, 2b usw. einerseits und dem Rohboden 1 und dem durch die Bretter 10 gebildeten Blindboden andererseits wird vorzugsweise zumindest teilweise durch Matten 25 aus Kunststoff oder auch aus atmungsfähigem Material ausgefüllt, wobei die Schicht 25 vorzugsweise unter Einhaltung eines vorgegebenen Abstandes zum Blindboden 10 eingesetzt wird, um eine Ventilation des Blindbodens zu ermöglichen.The space between the individual vibrating beams 2a, 2b etc. on the one hand and the unfinished floor 1 and the blind floor formed by the boards 10 on the other hand is preferably at least partially filled by mats 25 made of plastic or also of breathable material, the layer 25 preferably is used in compliance with a predetermined distance to the blind floor 10 to allow ventilation of the blind floor.

Bei der Darstellung nach Fig. 3a wird der Fall angenommen, daß eine Kraft F auf die obere Gurtbrettlage im Bereich des Distanzelements 9b wirkt. Hierbei spielt die Elastizität der oberen Gurtbrettlage 7 keine die Betrachtung beeinflussende Rolle. Die Kraft F wird hierbei durch die Elastizität des Distanzelements 9b beeinflußt und durch das Federverhalten der unteren Gurtbrettlage 8 im Bereich des Distanzelements 9b sowie durch die Elastizität der beiden elastischen Klötze 4b, 4c aufgenommen. Bei der Darstellung nach Fig. 3b wirkt die Kraft F auf die obere Gurtbrettlage 7 etwa in der Mitte zwischen den beiden Distanzelementen 9b, 9c, wodurch das Schwingverhalten des Schwingträgers durch die Elastizität der oberen Gurtbrettlage bestimmt wird sowie durch die Elastizität der beiden elastischen Distanzelemente 9b, 9c und den elastischen Distanzklotz 4c sowie zusätzlich durch die Elastizität der unteren Gurtbrettlage 8 infolge der Kraftverteilung und der damit im Bereich der Distanzelemente 9b, 9c auf den darunter befindlichen freischwingenden Abschnitt der unteren Gurtbrettlage 8 wirkenden Kraftkomponenten. In beiden Fällen gemäß Fig. 3a und 3b wird somit das Schwingverhalten durch die untere Gurtbrettlage mitbestimmt. In beiden Fällen wird das Schwingverhalten des Schwingbodens gleichfalls mitbestimmt durch ein oder zwei der Distanzelemente und durch zwei oder eines der elastischen Distanzklötze.In the illustration according to FIG. 3a, the case is assumed that a force F acts on the upper belt board layer in the area of the spacer element 9b. The elasticity of the upper belt board layer 7 does not play a role influencing the consideration. The force F is influenced here by the elasticity of the spacer element 9b and absorbed by the spring behavior of the lower belt board layer 8 in the region of the spacer element 9b and by the elasticity of the two elastic blocks 4b, 4c. 3b, the force F acts on the upper belt board layer 7 approximately in the middle between the two spacer elements 9b, 9c, as a result of which the vibration behavior of the vibration carrier is determined by the elasticity of the upper belt board layer and by the elasticity of the two elastic spacer elements 9b , 9c and the elastic spacer block 4c and additionally by the elasticity of the lower belt board layer 8 as a result of the force distribution and the force components acting on the free-floating section of the lower belt board layer 8 in the area of the spacer elements 9b, 9c. In both cases according to FIGS. 3a and 3b, the vibration behavior is thus also determined by the lower layer of the belt board. In both cases, the vibration behavior of the vibrating floor is also determined by one or two of the spacer elements and by two or one of the elastic spacer blocks.

Demgegenüber wird bei einem bekannten Schwingboden der in Verbindung mit dem DE-U-83 29 011 beschriebenen Art das Schwingverhalten des Schwingträgers praktisch nicht mit beeinflußt durch die untere Gurtbrettlage, wie die Fig. 4a,4b zeigen. Gemäß Fig. 4a wirkt die Kraft auf die obere Gurtbrettlage 7′ etwa in der Mitte zwischen den beiden Distanzelementen 9′b und 9′c, so daß eine Kraftverteilung auftritt, welche durch die nichtelastischen Distanzelemente 9′b, 9′c nicht beeinflußt wird, ebenso nicht durch die darunter befindliche Gurtbrettlage 8′, da diese im Bereich der Distanzelemente 9′b, 9′c jeweils unmittelbar mittels der elastischen Stützklötze 4′c und 4′b abgestützt ist. Damit wird das Schwingverhalten bei einem Schwingträger der in Fig. 4a gezeigten Weise ausschließlich bestimmt durch die elastischen Stützklötze 4′b und 4′c. Tritt die Kraft bei diesem bekannten Schwingträger auf die obere Gurtbrettlage 7′ im Bereich eines Distanzelements 9′c oder 9′b auf, so wird das Schwingverhalten dieses Schwingträgers weder durch die obere Gurtbrettlage noch durch die untere Gurtbrettlage bestimmt, sondern wiederum ausschließlich durch den unteren elastischen Stützklotz 4′c.In contrast, in a known vibrating floor of the type described in connection with DE-U-83 29 011, the vibrating behavior of the vibrating carrier is practically not influenced by the lower belt board layer, as shown in FIGS. 4a, 4b. 4a, the force acts on the upper belt board layer 7 'approximately in the middle between the two spacer elements 9'b and 9'c, so that a force distribution occurs, which is not influenced by the non-elastic spacer elements 9'b, 9'c, nor by the underlying belt board layer 8 ', since these in the area of the spacer elements 9'b, 9'c each directly by means of the elastic support blocks 4'c and 4'b is supported. Thus, the vibration behavior in a vibration carrier of the type shown in Fig. 4a is determined exclusively by the elastic support blocks 4'b and 4'c. If the force occurs in this known vibration carrier on the upper belt board layer 7 'in the area of a spacer 9'c or 9'b, the vibration behavior of this vibration carrier is determined neither by the upper beltboard layer nor by the lower beltboard layer, but again exclusively by the lower one elastic support block 4'c.

Vorstehende Ausführungen zeigen, daß gemäß vorliegender Erfindung das Schwingverhalten eines Schwingbodens mit dem erfindungsgemäß benutzten Schwingträger auf optimale Weise abgestimmt werden kann und zwar durch mehrere Komponenten, nämlich die elastischen Distanzelemente, die untere Gurtbrettlage und die Stützklötze sowie auch durch die obere Gurtbrettlage selbst.The above explanations show that, according to the present invention, the vibration behavior of a vibration floor can be optimally coordinated with the vibration carrier used according to the invention, namely by means of several components, namely the elastic spacer elements, the lower belt board layer and the support blocks, and also by the upper belt board layer itself.

Bei den in Verbindung mit Fig. 1 bis 3 beschriebenen Ausführungsformen haben die Distanzelemente 9 jeweils eine Breite, die etwa der Breite der Klötze 4 entspricht und die nur einen Bruchteil der Gesamtlänge der Gurtbretter beträgt, wobei die Gurtbretter vorzugsweise eine Länge von etwa 3 m oder 3,5 m haben. Gemäß einer Abwandlung ist vorgesehen, daß die Distanzelemente 9 und/oder die Abstützklötze 4 eine gegenüber der Darstellung nach Fig. 1 bis 3 wesentlich größere Breite haben, mithin in Form von Streifen parallel zu den Gurtbrettlagen verlaufend vorgesehen sind. In einem solchen Fall wird das Material für die Distanzelemente 9 und/oder die Klötze 4 mit einer höheren Nachgiebigkeit gewählt als in Verbindung mit den klotzförmigen Distanzelementen 9 und 4 bei den Ausführungsformen nach Fig. 1 bis 3 beschrieben wurde, so daß das Schwingverhalten des Schwingträgers in der beschriebenen Weise durch die Elastizität der oberen und/oder unteren Gurtbrettlage 7, 8 mitbestimmt wird.In the embodiments described in connection with FIGS. 1 to 3, the spacer elements 9 each have a width which corresponds approximately to the width of the blocks 4 and which is only a fraction of the total length of the belt boards, the belt boards preferably having a length of approximately 3 m or 3.5 m. According to a modification, it is provided that the spacer elements 9 and / or the support blocks 4 have a width which is substantially greater than that shown in FIGS. 1 to 3, and are therefore provided in the form of strips running parallel to the belt board layers. In such a case, the material for the spacer elements 9 and / or the blocks 4 is selected with a higher flexibility than in connection with the block-shaped spacer elements 9 and 4 has been described in the embodiments according to FIGS. 1 to 3, so that the vibration behavior of the vibration carrier is determined in the manner described by the elasticity of the upper and / or lower belt board layer 7, 8.

Nach den DIN-Normen gemäß DIN 18032 Teil 2 gelten folgende Anforderungen für einen flächenelastischen Sportboden der erfindungsgemäßen Art:

For the main criteria of power reduction and standard deformation, tests have shown the following values determined at the usual six measuring points of a moving floor, again in comparison with a moving floor according to DE-U-83 29 011:
Figure imgb0003

Aus vorstehender tabellarischen Aufstellung geht hervor, daß der erfindungsgemäße Schwingboden die nach den DIN-Vorschriften vorgegebenen Mindestwerte mehr als erfüllt und die Maximalwerte weit unterschreitet.The table above shows that the vibrating floor according to the invention more than meets the minimum values specified in accordance with the DIN regulations and falls well below the maximum values.

Wenn die Klötze und Distanzelemente aus elastischem Material bestehen, ergibt sich eine höhere Elastizität und eine Verminderung der Ausbreitung der Mulde, da durch die elastischen Distanzelemente eine seitliche Verschiebung der Gurtbrettlagen möglich ist.If the blocks and spacer elements are made of elastic material, there is a higher elasticity and a reduction in the spreading of the trough, since the elastic spacer elements make it possible to shift the belt board layers laterally.
