Abstract

In an aeration mat for a whirlpool bath, a mat-like supporting body is provided which forms a support surface for the body of the person to be treated, formed for example by sectional rods and support elements (7). Protruding supporting projections (10) are provided on this support surface or on the support elements (7), and are designed in the manner of resilient plates and inserted into apertures (19) in the support surface, so that they form an advantageous bearing surface for the body of the person with a relatively flat spring characteristic. All the supporting projections (10) of a support element (7) can in a simple manner be designed integrally with one another in that they are jointly moulded directly onto the support element (7) in the form of plastics injection mouldings and are connected to one another on the underside of the support element via a ribbon-shaped connecting section (14). Edge-protection strips (25) can also be moulded on in a similar manner. <IMAGE>

Description

Die Erfindung betrifft eine Luftverteiler-Unterlage für eine Sprudel-Badeeinrichtung gemäß Oberbegriff des Anspruchs 1.The invention relates to an air distributor underlay for a bubble bath device according to the preamble of claim 1.

Eine derartige Unterlage bzw. ein solcher für die körpernahe Anordnung zur zu behandelnden Person bestimmter Anlageteil weist zur Erzielung günstiger Wirkungen einen rost- bzw. mattenartigen Tragkörper auf, der mit einer dem Körper der zu behandelnden Person zugekehrt anzuordnenden Seite, wie einer Körper-Anlageseite und mit Luft-Austrittsöffnungen so versehen ist, daß die austretende Luft stimulierende Reize bei der zu behandelnden Person bewirkt.Such a support or such a plant part intended for the body-close arrangement to the person to be treated has a rust-like or mat-like supporting body for achieving favorable effects, which has to be arranged with a side facing the body of the person to be treated, such as a body contact side and is provided with air outlet openings so that the air exiting stimulates the person to be treated.

Bei bekannten Luftverteiler-Unterlagen ist die Anlageseite durch die Oberfläche relativ harter Bauteile, beispielsweise im wesentlichen formstabiler Tragelemente gebildet, was trotz des im Badewasser auf den Körper der Person wirkenden Auftriebes vorallem dann zu einem relativ unbequemen Liegen führen kann, wenn lange Behandlungszeiten erwünscht sind. So sind gemäß der FR-A-398 060 Tragekörper aus Porzellan oder Hartholz vorgesehen, die keinerlei Nachgiebigkeit besitzen. In der WO 84/04253 ist eine als Matte ausgebildete Unterlage offenbart, bei der Magnete in Öffnungen von Tragelementen eingesetzt werden können. Das Problem des Liegekomforts für den Benutzer ist in dieser Druckschrift nicht angesprochen. Auch ergibt sich bei vielen bekannten Unterlagen eine relativ großflächige Anlage des Körpers, wobei die anliegenden Bereiche den Reizimpulsen des Behandlungsmediums nicht oder wesentlich weniger als die nicht anliegenden Bereiche ausgesetzt sind.In known air distribution underlays, the contact side is formed by the surface of relatively hard components, for example essentially dimensionally stable supporting elements, which, despite the buoyancy acting on the body of the person in the bathing water, can lead to a relatively uncomfortable lying position if long treatment times are desired. So In accordance with FR-A-398 060, supporting bodies made of porcelain or hardwood are provided which have no flexibility. WO 84/04253 discloses a base designed as a mat, in which magnets can be used in openings in support elements. The problem of lying comfort for the user is not addressed in this document. Many known documents also result in a relatively large area of contact with the body, with the adjacent areas not being exposed to the stimulus impulses of the treatment medium or being exposed to less than the areas not adjacent.

Der Erfindung liegt des weiteren die Aufgabe zugrunde, eine Luftverteiler-Unterlage der genannten Art zu schaffen, durch welche Nachteile bekannter Ausbildungen vermieden sind und welche insbesondere eine verhältnismäßig weiche Anlage des Körpers der zu behandelnden Person selbst dann gewährleistet, wenn die Anlagefläche im Verhältnis zur Gesamtfläche relativ klein ist.The invention is furthermore based on the object of creating an air distributor underlay of the type mentioned, by means of which disadvantages of known designs are avoided and which, in particular, ensures a relatively soft contact of the body of the person to be treated even if the contact surface is in relation to the total area is relatively small.

Diese Aufgabe wird durch eine Luftverteiler-Unterlage mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by an air distributor pad with the features of claim 1.

Es sind Tragvorsprünge vorgesehen, die wenigstens einen Teil der Anlageseite bzw. Anlagefläche bilden und durch die Formgebung ihrer Anlageflächen und/oder durch eigene Elastizität mindestens teilweise federnd ausgebildet sind. Bevorzugte Ausführungsformen der Unterlage gemäß der Erfindung ergeben sich aus den abhängigen Ansprüchen.Support projections are provided which form at least part of the contact side or contact surface and are at least partially resilient due to the shape of their contact surfaces and / or due to their own elasticity. Preferred embodiments of the base according to the invention result from the dependent claims.

Die Tragvorsprünge sind in Öffnungen des Tragkörpers angeordnet, so daß eine sichere Verbindung selbst dann gewährleistet ist, wenn die Tragvorsprünge sehr flach bzw. niedrig ausgebildet sind. Beispielsweise nur in der Größenordnung von etwa einem bis wenigen Millimetern oder in der Größenordnung der Wandungsdicke des Tragkörpers vorstehen. Die Öffnungen können auch für einen Teil des Federweges der Tragvorsprünge zur Verfügung stehen, so daß diese mit einer relativ flachen Federkennlinie ausgebildet werden können. Für die Aufnahme der Tragvorsprünge ist es denkbar, diese lediglich kraftschlüssig mit dem Tragkörper zu verbinden bzw. in die Öffnungen eingreifen zu lassen oder aber eine formschlüssige Verbindung, beispielsweise durch Hintergreifen vorzusehen. Dabei können die Tragvorsprünge quer zur Anlageseite formschlüssig gesichert in die Öffnungen eingreifen und dabei insbesondere jeweils mit einer Ringnut den Rand der zugehörigen, als Durchbruch ausgebildeten Öffnung beiderseits umgreifen.The support projections are arranged in openings of the support body, so that a secure connection is ensured even if the support projections are very flat or low. For example, only in the order of magnitude protrude from about one to a few millimeters or in the order of the wall thickness of the support body. The openings can also be available for part of the spring travel of the support projections, so that they can be formed with a relatively flat spring characteristic. For the reception of the support projections, it is conceivable to merely connect them to the support body in a non-positive manner or to have them engage in the openings, or to provide a positive connection, for example by reaching behind. In this case, the support projections can engage in the openings in a positively locking manner transversely to the contact side and, in each case, in each case encompass the edge of the associated opening designed as an opening in each case with an annular groove.

Damit jeder Tragvorsprung keine zu hohen Punktbelastungen ausübt, sind die Tragvorsprünge zweckmäßig flächig, insbesondere mit balliger Anlagefläche ausgebildet, wobei ihre Höhe zweckmäßig mehrfach kleiner als ihre Weite bzw. ihr Durchmesser ist.So that each support projection does not exert excessive point loads, the support projections are expediently flat, in particular designed with a spherical contact surface, their height usefully being several times smaller than their width or diameter.

In Weiterbildung können die Tragvorsprünge rasterartig im wesentlichen gleichmäßig über die Anlageseite verteilt sein.In a further development, the support projections can be distributed in a grid-like manner essentially uniformly over the contact side.

Eine besonders vorteilhafte Weiterbildung des Erfindungsgegenstandes besteht darin, daß mehrere Tragvorsprünge eines Tragkörpers bzw. eines Tragelementes, insbesondere solche, die benachbart zueinanderliegen, einteilig miteinander verbunden sind, so daß sich einerseits eine einfache Herstellung und andererseits auch bei kleinen Querschnitten eine sichere Verbindung mit dem Tragkörper ergibt. Dabei können vorteilhaft zum Beispiel alle Tragvorsprünge eines Tragelementes bzw. eines Tragkörpers einteilig miteinander verbunden sein bzw. es können Tragvorsprünge, die in mindestens einer Reihe hintereinander liegen, über einen bandförmigen Verbindungsabschnitt miteinander verbunden sein, über den die Tragvorsprünge zur Anlageseite vorstehen. Besonders vorteilhaft ist es, wenn die einteilige Verbindung bzw. der Verbindungsabschnitt nicht an der Anlageseite des Tragkörpers, sondern gegenüber dieser zurückversetzt, insbesondere an dessen Unterseite liegt. Auch in diesem Fall sind dann die Öffnungen, die sacklochartige Vertiefungen an der Anlageseite des Tragkörpers sein könnten, vorteilhaft als Durchbrüche bzw. Durchgangsöffnungen ausgebildet, die zweckmäßig über ihre gesamte Axialerstreckung konstante Querschnitte haben und deren Axialerstreckung etwa in der Größenordnung der Dicke des Verbindungsabschnittes bzw. des Maßes liegen kann, um welches die Tragvorsprünge über die Anlageseite vorstehen.A particularly advantageous development of the subject matter of the invention is that a plurality of supporting projections of a supporting body or a supporting element, in particular those which are adjacent to one another, are integrally connected to one another, so that on the one hand simple manufacture and on the other hand a secure connection to the supporting body even with small cross sections results. In this case, for example, all the support projections of a support element or of a support body can advantageously be connected to one another in one piece, or support projections that are in at least one Row are one behind the other, connected to each other via a band-shaped connecting section, over which the support projections protrude to the contact side. It is particularly advantageous if the one-piece connection or the connection section is not set back on the contact side of the support body, but rather in relation to the latter, in particular on its underside. In this case, too, the openings, which could be blind-hole-like depressions on the contact side of the supporting body, are advantageously designed as openings or through-openings which expediently have constant cross sections over their entire axial extent and whose axial extent is approximately in the order of magnitude of the thickness of the connecting section or of the dimension by which the support projections protrude beyond the contact side.

Bevorzugt ist eine erfindungsgemäße Unterlage so ausgebildet, daß eine Seitenflanke einer einen jeweiligen Tragvorsprung des Tragkörpers quer zur Anlageseite sichernden Nut durch die Unterseite eines Vorsprungtellers des Tragvorsprunges und eine gegenüberliegende Seitenflanke durch die im wesentlichen ganzflächig an der Unterseite des Tragelementes anliegende Oberseite eines Verbindungsabschnittes für die Tragvorsprünge gebildet ist.An underlay according to the invention is preferably designed such that a side flank of a groove securing a respective support projection of the support body transversely to the contact side through the underside of a projection plate of the support projection and an opposite side flank through the upper side of a connecting section for the support projections, which lies essentially over the entire surface on the underside of the support element is formed.

Es ist denkbar, den jeweiligen Tragvorsprung so als Vollquerschnitt-Teil auszubilden, daß er praktisch nur aufgrund seiner druckelastischen Eigenschaften oder aufgrund einer geschlossen zelligen Schaumstruktur federnd ist. Vorzugsweise ist der Tragvorsprung membranartig druckelastisch ausgebildet bzw. in seiner Federbewegung wenigstens teilweise auf Biegung beanspruchbar. Hierzu kann der Tragvorsprung zum Beispiel an seiner Unterseite bzw. an der Unterseite des Verbindungsabschnittes kugelkalottenförmig oder ähnlich so ausgehöhlt sein, daß seine Wandungsdicke im Bereich seines Zentrums wesentlich kleiner als seine Gesamthöhe ggf. einschließlich des Verbindungsabschnittes ist, wobei diese Wandungsdicke etwa in der Größenordnung desjenigen Maßes liegen kann, um welches der Tragvorsprung über die Anlageseite vorsteht. Von dieser Zone bzw. diesem Zentrum geringster Wandungsdicke nimmt die Wandungsdicke des Tragvorsprunges zweckmäßig radial nach außen progressiv zu. Als Werkstoffe für den Tragvorsprung eignen sich Weichpolyurethan, Weichpolyvinylchlorid, Gummi o.dgl..It is conceivable to design the respective support projection as a full cross-section part in such a way that it is only resilient in practice only because of its pressure-elastic properties or because of a closed-cell foam structure. The supporting projection is preferably designed to be pressure-elastic in the form of a membrane or can at least partially be subjected to bending in its spring movement. For this purpose, the support projection can, for example, be hollowed out in the shape of a spherical cap or the like on its underside or on the underside of the connecting section in such a way that its wall thickness is in the region of its center is substantially smaller than its total height, including the connecting section, where appropriate, this wall thickness can be approximately in the order of the dimension by which the supporting projection protrudes beyond the contact side. The wall thickness of the support projection expediently increases progressively radially outward from this zone or this center of minimal wall thickness. Suitable materials for the supporting projection are soft polyurethane, soft polyvinyl chloride, rubber or the like.

Für günstige Federungseigenschaften ist es auch vorteilhaft, wenn die Wandungsdicke des Tragvorsprunges kleiner als die lichte Weite bzw. der Innendurchmesser der Öffnung im formstabilen Element ist. Die Außenweite bzw. der Außendurchmesser der vorzugsweise kreisrunden Tragvorsprünge liegt zweckmäßig in der Größenordnung zwischen 10 bis 30 mm und die Weite der Öffnung ist demgegenüber nur wenige Millimeter kleiner.For favorable suspension properties, it is also advantageous if the wall thickness of the support projection is smaller than the clear width or the inner diameter of the opening in the dimensionally stable element. The outer width or the outer diameter of the preferably circular support projections is expediently in the order of magnitude between 10 to 30 mm and the width of the opening is only a few millimeters smaller.

Durch die beschriebene Ausbildung kann die Wandung des Tragvorsprunges so gestaltet werden, daß dieser im Axialschnitt kuppelförmig ist. Die Form des Tragvorsprunges bzw. die Kuppelform ist zweckmäßig so gewählt, daß der Tragvorsprung monostabil elastisch stets in seine Ausgangslage, nämlich in seine über die Anlageseite vorspringende Traglage zurückspringt und in der eingedrückten Lage nicht eine weitere selbsthaltende Stellung findet.Due to the design described, the wall of the support projection can be designed so that it is dome-shaped in axial section. The shape of the supporting projection or the dome shape is expediently chosen so that the supporting projection always springs back monostably elastically into its starting position, namely into its supporting position projecting over the contact side, and does not find another self-retaining position in the pressed-in position.

Der Tragkörper bzw. die Tragelemente können zweckmäßig wenigstens teilweise luftführende bzw. luftleitende Hohlräume bilden, wie z.B. Leitungen etwa konstanten Querschnittes, wofür die Tragelemente als Kassetten, Profile o.dgl. ausgebildet sein können, die im Querschnitt über den Umfang, ggf. bis auf die Austrittsöffnungen und Einlaß-Anschlüsse geschlossen sind.The support body or the support elements can advantageously at least partially form air-guiding or air-guiding cavities, such as lines of approximately constant cross-section, for which the support elements as cassettes, profiles or the like. can be formed in cross-section over the circumference, if necessary, are closed except for the outlet openings and inlet connections.

Es ist auch denkbar, unmittelbar benachbart zu den Tragvorsprüngen bzw. in deren Bereich oder sogar an diesen Luft-Austrittsöffnungen vorzusehen, wodurch auch die Polsterwirkung der Tragvorsprünge erhöht werden kann. Insbesondere dann, wenn mindestens eine Austrittsöffnung die Wandung des Tragvorsprunges selbst durchsetzt, ist es vorteilhaft, wenn die Oberflächen der Tragvorsprünge Strukturierungen, insbesondere Noppen und/oder Vertiefungen aufweisen, wobei dann die Austrittsöffnungen zweckmäßig zwischen den Noppen bzw. in den Vertiefungen liegen. Luft-Austrittsöffnungen können beispielsweise in einem Kranz um die Mittelachse des jeweiligen Tragvorsprunges in diesem und/oder unmittelbar benachbart zu dessen Peripherie vorgesehen sein.It is also conceivable to provide directly adjacent to the support projections or in their area or even at these air outlet openings, as a result of which the cushioning effect of the support projections can also be increased. In particular, if at least one outlet opening passes through the wall of the support projection itself, it is advantageous if the surfaces of the support projections have structuring, in particular knobs and / or depressions, in which case the outlet openings are expediently located between the knobs or in the depressions. Air outlet openings can, for example, be provided in a ring around the central axis of the respective support projection in this and / or directly adjacent to its periphery.

Der Tragkörper bzw. das jeweilige Tragelement kann einteilig platten-, rost-, gitterförmig oder ähnlich ausgebildet sein. Zweckmäßig sind insbesondere formstabile Tragelemente vorgesehen, die einen oberen, die Tragvorsprünge aufnehmenden Tragsteg und vorzugsweise mindestens einen von diesem nach unten abstehenden Profilschenkel aufweisen, wobei diese Tragelemente jeweils U-profilförmig beispielsweise mit einer Breite ausgebildet sein können, die größer als ihre Schenkelhöhe ist. Dabei kann mindestens ein Profilschenkel des jeweiligen Tragelementes nach unten weiter als die Tragvorsprünge, insbesondere als ein Verbindungsabschnitt der Tragvorsprünge vorstehen. Aus den beschriebenen Tragelementen, die ihrerseits Luftführungen bilden, mit eingelegten bzw. eingeformten Luftkanälen versehen oder mit gesonderten, beispielsweise zwischen ihnen liegenden Luftkanälen zu dem Tragkörper verbunden sind, läßt sich die Roststruktur des Tragkörpers besonders einfach herstellen. Das jeweilige Tragelement kann zwar nur eine einzige, etwa in der Mitte seiner Breite liegende Reihe von Tragvorsprüngen aufweisen, wobei beispielsweise der Durchmesser der Tragvorsprünge des Tragkörpers größer als ein Drittel der Breite eines zugehörigen Tragelementes sein kann. Es ist jedoch auch denkbar, zwei oder mehr benachbarte bzw. parallele Reihen von Tragvorsprüngen an demselben Tragelement vorzusehen, wobei dann die Tragvorsprünge benachbarter Reihen zweckmäßig auf Lücke gegeneinander versetzt sind.The supporting body or the respective supporting element can be designed in one piece in the form of a plate, rust, lattice or the like. In particular, dimensionally stable supporting elements are expediently provided, which have an upper supporting web, which receives the supporting projections, and preferably at least one profile leg projecting downward therefrom, wherein these supporting elements can each be U-shaped, for example, with a width that is greater than their leg height. At least one profile leg of the respective support element can protrude further downward than the support projections, in particular as a connecting section of the support projections. The rust structure of the support body can be produced particularly easily from the support elements described, which in turn form air ducts, are provided with inserted or molded air channels or are connected to the support body with separate air channels, for example between them. The respective The support element can only have a single row of support projections approximately in the middle of its width, it being possible for example for the diameter of the support projections of the support body to be greater than one third of the width of an associated support element. However, it is also conceivable to provide two or more adjacent or parallel rows of support projections on the same support element, in which case the support projections of adjacent rows are expediently offset from one another with a gap.

Statt der beschriebenen Ausbildung mit Tragvorsprüngen oder zusätzlich hierzu lassen sich Längskanten des Tragkörpers bzw. der Tragelemente sehr einfach zur Vermeidung scharfer Kanten, zur Erzielung weicher Stützflächen gegenüber der Badewanne o.dgl. verkleiden, wenn an mindestens einer Längskante ein Kantenschutzprofil angeordnet ist, das vorzugsweise als den zugehörigen Rand umgreifendes Längsprofil ausgebildet ist, welches mit Ansätzen aneinander zugekehrten Profilschenkeln in Öffnungen bzw. Löcher des zugehörigen Randes eingreift.Instead of the design described with support projections or in addition to this, longitudinal edges of the support body or the support elements can be very easily to avoid sharp edges, to achieve soft support surfaces compared to the bathtub or the like. Dress up if an edge protection profile is arranged on at least one longitudinal edge, which is preferably designed as a longitudinal profile encompassing the associated edge, which engages with openings facing profile legs in openings or holes in the associated edge.

Sowohl die Tragvorsprünge, die teilweise unterschiedlich oder vorzugsweise alle gleich ausgebildet sein können, wie auch die Kantenschutzprofile sind zweckmäßig durch Spritzgußteile aus Kunststoff gebildet, die unmittelbar an den Tragkörper bzw. das jeweilige Tragelement, beispielsweise in einem Arbeitsgang gemeinsam, angeformt sind, so daß sich bei einfacher Herstellung eine besonders enge und spielfreie Befestigung des jeweiligen Spritzgußteiles ergibt.Both the support projections, which can be partially different or preferably all the same, as well as the edge protection profiles are expediently formed by injection molded parts made of plastic, which are attached directly to the support body or the respective support element, for example in are molded together in one operation, so that there is a particularly tight and play-free attachment of the respective injection molded part with simple manufacture.

Die Luftverteiler-Unterlage 1 gemäß den Fig. 1 bis 4, die auch als reine Fußunterlage für eine Fußbehandlung oder für die Behandlung anderer begrenzter Körperbereiche bemessen sein kann, dient zur Anordnung auf dem Boden einer wassergefüllten Badewanne, wobei sie sich zweckmäßig im wesentlichen über die gesamte Länge des Wannenbodens erstreckt und auch einen Rückenanlageteil für die Anordnung an der schräg ansteigenden Rückenwand der Badewanne aufweisen kann. Die Unterlage 1 ist im wesentlichen durch einen rost- bzw. mattenförmigen, jedoch in sich im wesentlichen formstabilen Tragkörper 2 gebildet, der einteilig ausgebildet oder aus in Längsrichtung gelenkig aneinanderschließenden Mattenglieder 3 etwa gleicher Größe zusammengesetzt sein kann, so daß sich die Unterlage zur Aufbewahrung paketartig, winkel- bzw. U-förmig oder ähnlich zusammenfalten läßt. Im dargestellten Beispiel sind für den Boden der Badewanne drei Mattenglieder 3 vorgesehen.The air distribution pad 1 according to FIGS. 1 to 4, which can also be dimensioned as a pure foot pad for a foot treatment or for the treatment of other limited body areas, is used for arrangement on the floor of a water-filled bathtub, whereby it is expedient essentially over the stretches the entire length of the tub floor and also a backrest part for the arrangement on the inclined slope Back wall of the bathtub can have. The base 1 is essentially formed by a rust or mat-shaped, but essentially dimensionally stable support body 2, which is formed in one piece or can be composed of mat members 3 which are hinged to one another in the longitudinal direction and can be composed of approximately the same size, so that the base is stored in a packet-like manner , can be folded in an angle or U-shape or similar. In the example shown, three mat members 3 are provided for the bottom of the bathtub.

Am Fußende 4 des Tragkörpers 2 ist etwa in der Mitte von dessen Breite ein Lufteintritts-Anschluß 5 für den Anschluß eines flexiblen Luftschlauches vorgesehen, der die Unterlage 1 mit einem außerhalb der Badewanne stehenden, ein Druckluftgebläse aufweisenden Grundgerät für die Luftversorgung verbindet. Der Tragkörper 1 ist mit im wesentlichen über seine Länge durchgehenden und sich ebenfalls im wesentlichen in seiner Längsrichtung erstreckenden, beispielsweise geradlinigen Luftkanälen 6 versehen, die durch Rohrprofile gebildet oder in den Tragkörper 1 eingeformt sein können. Die Luftkanäle 6 sind mit beispielsweise zwischen ihnen und an den äußeren Längsseiten des Tragkörpers 2 liegenden Tragelementen 7 zu dem Tragkörper 2 verbunden, wobei die Tragelemente 7 durch gesonderte Bauteile gebildet oder einteilig mit den Luftkanälen 6 ausgebildet sein können. Jedes Mattenglied 3 bildet dabei einen in sich geschlossenen Tragkörper, wobei jedoch die Luftkanäle 6 einteilig über die gesamte Länge der Unterlage 1 durchgehen können. Die Tragelemente des Tragkörpers 2 bzw. des jeweiligen Mattengliedes 3 können, wie dargestellt, stabförmig geradlinig und beispielsweise durch gesonderte Strangprofilabschnitte gebildet oder an ihren Enden durch entsprechend gesonderte oder einteilig mit ihnen ausgebildete Querzargen gitterartig miteinander verbunden sein oder aber ihre Verbindung kann ausschließlich nur über die Luftkanäle 6 erfolgen.At the foot end 4 of the support body 2, an air inlet connection 5 is provided approximately in the middle of the width thereof for the connection of a flexible air hose, which connects the base 1 to a base unit for the air supply which is located outside the bath tub and has a compressed air blower. The support body 1 is provided with substantially continuous lengthways and also essentially in its longitudinal direction, for example rectilinear air channels 6, which can be formed by tubular profiles or molded into the support body 1. The air channels 6 are connected to the support body 2, for example, with support elements 7 lying between them and on the outer longitudinal sides of the support body 2, wherein the support elements 7 can be formed by separate components or can be formed in one piece with the air channels 6. Each mat member 3 forms a self-contained support body, but the air channels 6 can pass in one piece over the entire length of the base 1. The support elements of the support body 2 or of the respective mat member 3 can, as shown, be linear and linear, for example formed by separate extruded sections or at their ends by correspondingly separate or in one piece cross frames formed with them can be connected to one another like a grid, or their connection can only take place via the air channels 6.

Der Tragkörper 2 bzw. die Mattenglieder 3 bilden eine im Gebrauch im wesentlichen oben liegende Anlageseite 8 für die die Unterlage benutzende Person. Durchtritte für die der Unterlage 1 zugeführte Gebläseluft sind in dieser Anlageseite im wesentlichen über die gesamte Grundfläche der Unterlage 1 gleichmäßig verteilt vorgesehen, wobei im dargestellten Ausführungsbeispiel diese Durchtritte unmittelbar durch Luft-Austrittsöffnungen 9 gebildet sind, die nach Art von Perforationen die oberen Wandungen der Luftkanäle 6 durchsetzen. An der Anlageseite 8 sind des weiteren rasterartig gleichmäßig verteilte Tragvorsprünge 10 vorgesehen, die wesentlich größer als die Austrittsöffnungen 9 und alle gleich ausgebildet sind, obwohl auch Gruppen mit unterschiedlich ausgebildeten Tragvorsprüngen je nach zu tragender Körperpartie denkbar sind. Die Tragvorsprünge 10 liegen zwischen benachbarten Längsreihen von Austrittsöffnungen 9 und können ebenfalls in solchen Längsreihen mit einem Zwischenabstand vorgesehen sein, der etwa in der Größenordnung ihrer Außenweite bzw. ihres Außendurchmessers liegt.The support body 2 or the mat members 3 form a plant side 8 which is essentially at the top for the person using the base. Passages for the blower air supplied to the underlay 1 are provided in this plant side essentially uniformly distributed over the entire base area of the underlay 1, in the exemplary embodiment shown these passages being formed directly by air outlet openings 9 which, in the manner of perforations, form the upper walls of the air ducts 6 enforce. On the plant side 8 there are also grid-like support projections 10 which are substantially larger than the outlet openings 9 and all of the same design, although groups with differently designed support projections are also conceivable depending on the body part to be worn. The support projections 10 lie between adjacent longitudinal rows of outlet openings 9 and can also be provided in such longitudinal rows with an intermediate distance which is approximately in the order of magnitude of their outside width or outside diameter.

Jeder Tragvorsprung 10, der im dargestellten Ausführungsbeispiel in Draufsicht kreisrund ist, aber auch oval, angenähert rechteckig bzw. quadratisch, dreieckförmig oder ähnlich ausgebildet sein kann, bildet einen über die Anlageseite 8 des zugehörigen Tragelementes 7 verhältnismäßig flach vorstehenden Vorsprungsteller 11, der mit seinen einen Stirnseite im wesentlichen ganzflächig die zweckmäßig nach oben ballig gekrümmte Anlagefläche 31 für den Körper der zu behandelnden Person bildet. An die untere Stirnfläche des Vorsprungstellers 11 schließt unmittelbar ein im Außendurchmesser nur geringfügig reduzierter und sehr kurzer Schaft 12 an, der mit seinem Außenumfang die Bodenfläche einer radial nach außen offenen Ringnut 13 bildet und an seinem vom Vorsprungsteller 11 abgekehrten Ende in einen ebenfalls einteilig mit ihm ausgebildeten, jedoch bandförmigen Verbindungsabschnitt 14 übergeht. Die Unterseite des Vorsprungstellers 11 bildet somit eine ringförmige Schulter zur Abstützung am Tragelement 7 und als obere bzw. nach unten weisende Seitenflanke 15 der Ringnut 13, während die im wesentlichen durchgehend ebene Oberseite des im Querschnitt rechteckig flachbandförmigen Verbindungsabschnittes 14 die andere Seitenflanke 16 der Ringnut 13 sowie in Längsrichtung des Verbindungsabschnittes 14 daran anschließende, zwischen benachbarten Tragvorsprüngen 10 liegende Oberflächenabschnitte für die Anlage des Verbindungsabschnittes 14 an der Unterseite des Tragelementes 7 bildet.Each support projection 10, which in the illustrated embodiment is circular in plan view, but also oval, approximately rectangular or square, triangular or similar, forms a projection plate 11 projecting relatively flat over the contact side 8 of the associated support element 7, with its one The end face forms essentially the entire surface, which expediently upwardly curved contact surface 31 for the body of the person to be treated. The lower end face of the projection plate 11 is immediately followed by a shaft 12 which is only slightly reduced in outer diameter and is very short which, with its outer circumference, forms the bottom surface of a radially outwardly open annular groove 13 and at its end facing away from the projection plate 11 merges into a connecting section 14 which is also formed in one piece with it but is band-shaped. The underside of the projection plate 11 thus forms an annular shoulder for support on the support element 7 and as an upper or downward-facing side flank 15 of the ring groove 13, while the essentially continuous flat top side of the connecting section 14 with a rectangular flat cross section has the other side flank 16 of the ring groove 13 as well as in the longitudinal direction of the connecting section 14 adjoining surface sections lying between adjacent supporting projections 10 for the contact of the connecting section 14 on the underside of the supporting element 7.

Jeder Tragvorsprung 10 ist dadurch nach Art einer kuppelartigen Federmembran ausgebildet, daß er von seiner von der Anlagefläche 31 abgekehrten Seite her mit einer annähernd kugelkalottenförmigen Aushöhlung 17 versehen ist, deren Krümmungsradius wesentlich kleiner als derjenige der Anlagefläche 31 ist. Dadurch bildet der Tragvorsprung 10 eine membranartige Stirn-Wandung 18 unterschiedlicher, nämlich vom Zentrum der Anlagefläche 31 radial nach außen zunehmender Dicke, welche in ihrem dünnsten Bereich etwa der Dicke des Tellervorsprunges 10 gleich ist, während sie im Bereich des Schaftes 12 der Gesamtdicke aus Vorsprungsteller 11, Schaft 12 und Verbindungsabschnitt 14 entspricht. Die den Verbindungsabschnitt 14 und den hohlen Schaft 12 durchsetzende Aushöhlung 17 weist an der im wesentlichen ebenen Unterseite des Verbindungsabschnittes 14 ihre größte Weite auf.Each support projection 10 is designed in the manner of a dome-like spring membrane in that it is provided from its side facing away from the contact surface 31 with an approximately spherical cap-shaped cavity 17, the radius of curvature of which is substantially smaller than that of the contact surface 31. As a result, the support projection 10 forms a membrane-like end wall 18 of different thickness, namely increasing radially outwards from the center of the contact surface 31, which is approximately the same in its thinnest area as the thickness of the plate projection 10, while in the area of the shaft 12 it is the total thickness of the projection plate 11, shaft 12 and connecting section 14 corresponds. The hollow 17 passing through the connecting section 14 and the hollow shaft 12 has its greatest width on the essentially flat underside of the connecting section 14.

Für die Aufnahme bzw. für den Durchtritt des jeweiligen Tragvorsprunges 10 ist im Tragelement 7 eine zweckmäßig gleiche Grundform wie der Vorsprungsteller 11, nämlich beispielsweise kreisrunde bzw. zylindrische Grundform aufweisende Öffnung 19 vorgesehen, deren Rand 20 in die Ringnut 13 radial und/oder axial im wesentlichen spielfrei eingreift. Sämtliche Tragvorsprünge 10 des jeweiligen Tragelementes 7 sind einschließlich ihrer Schäfte und des oder der Verbindungselemente 14 in einem einzigen Spritzguß-Arbeitsgang unmittelbar an dieses Tragelement angeformt, so daß das Tragelement selbst, nämlich wenigstens im Bereich der Öffnung 19 bzw. des Randes 20 die Spritzgußform bildet und sich eine sehr feste Verbindung ergibt. Die Tragelemente 7 bestehen selbst zweckmäßig aus Kunststoff, jedoch aus einem wesentlich härteren Werkstoff als die Tragvorsprünge 10, nämlich beispielsweise aus Hart-PVC, PA, PP oder ABS. An die Tragvorsprünge 10 bzw. an den Verbindungsabschnitt 14 können noch zusätzliche Funktionsteile der Unterlage 1 angeformt sein, nämlich zum Beispiel nach unten vorstehende Standfüße, Saugnäpfe für die Verbindung mit dem Wannenboden o.dgl. Diese Funktionsteile liegen dann zweckmäßig zwischen benachbarten Tragvorsprüngen 10. Ist gemäß den Fig. 1 bis 4 nur eine Längsreihe von Tragvorsprüngen 10 je Tragelement 7 vorgesehen, so ist die Weite bzw. der Durchmesser des jeweiligen Tragvorsprunges 10 zweckmäßig größer als ein Drittel der Breite des Tragelementes.For the reception or for the passage of the respective support projection 10, the support element 7 is expediently the same basic shape as the projection plate 11, namely, for example circular or cylindrical basic shape opening 19 is provided, the edge 20 engages in the annular groove 13 radially and / or axially substantially without play. All of the support projections 10 of the respective support element 7, including their shafts and the connection element (s) 14, are molded directly onto this support element in a single injection molding operation, so that the support element itself, namely at least in the region of the opening 19 or the edge 20, forms the injection mold and there is a very firm connection. The support elements 7 themselves suitably consist of plastic, but from a much harder material than the support projections 10, namely, for example, from hard PVC, PA, PP or ABS. Additional functional parts of the base 1 can be integrally formed on the supporting projections 10 or on the connecting section 14, namely, for example, feet protruding downwards, suction cups for the connection to the tub floor or the like. These functional parts are then expediently located between adjacent support projections 10. If, according to FIGS. 1 to 4, only one longitudinal row of support projections 10 is provided per support element 7, the width or the diameter of the respective support projection 10 is expediently greater than a third of the width of the support element .

Die die Tragvorsprünge 10 aufweisenden Tragelemente 7 können unterschiedlich oder alle im wesentlichen gleich ausgebildet sein. Im dargestellten Ausführungsbeispiel ist das jeweilige Tragelement 7 als U-Profil ausgebildet, dessen U-Quersteg einen oben etwa parallel zur Mattenebene liegenden und annähernd ebenen Tragsteg 22 bildet, von dem die unterschiedlich oder gleich hohen Profilschenkel 23 annähernd rechtwinklig nach unten stehen und abgerundet in den Tragsteg 22 übergehen. Die Höhe der Profilschenkel 23 ist wesentlich größer als die Dicke des Verbindungsabschnittes 14, so daß der die Tragvorsprünge 10 bildende Spritzgußteil 21 an der Unterseite vollständig versenkt innerhalb des Tragkörpers 2 bzw. des jeweiligen Tragelementes 7 liegt.The supporting elements 7 having the supporting projections 10 can be designed differently or all of them essentially the same. In the illustrated embodiment, the respective support element 7 is designed as a U-profile, the U-transverse web forms an approximately flat support web 22 lying approximately parallel to the mat plane at the top, from which the profile legs 23 of different or equal height are approximately at right angles downwards and rounded into the Pass over the web 22. The height of the profile leg 23 is much greater than the thickness of the connecting portion 14, so that the Injection molded part 21 forming support projections 10 is completely sunk on the underside within the support body 2 or the respective support element 7.

Der Rand jedes Profilschenkels 23 des Tragelementes 7 ist mit einem Kantenschutzprofil 25 versehen, das in gleicher Weise wie der Spritzgußteil 21 unmittelbar an das Tragelement 7 angeformt ist. Jedes Kantenschutzprofil 25 weist einen an der Längskante des zugehörigen Randes 24 eng anliegenden Profilquersteg 26 auf, der einteilig mit zwei im Abstand zueinander gegenüberliegenden und beiderseits an der Außenseite und an der Innenseite des Profilschenkels 23 eng anliegenden Profilschenkeln 27, 28 ausgebildet ist, welche gleich oder unterschiedlich hoch sein können. Die Profilschenkel 27, 28 und der Profil-Quersteg 26 weisen etwa gleiche Dicke auf, die annähernd in der Größenordnung der Wandungsdicke des Tragelementes 7 liegt. Der Rand 24 ist zwischen den Profilschenkeln 27, 28 mit einer über seine Länge durchgehenden Reihe von rasterartig eng beieinanderliegenden Löchern 29 versehen, deren Weite bzw. Innendurchmesser etwa in der Größenordnung der Wandungsdicke des Tragelementes 7 bzw. des Kantenschutzprofiles 25 liegen kann. In jedes Loch 29 greift ein dieses eng ausfüllender Sicherungszapfen 30 ein, der einteilig mit dem Kantenschutzprofil 25 ausgebildet ist und vorzugsweise mit beiden Enden einteilig in beide einander zugekehrten Innenseiten der beiden Profilschenkel 27, 28 übergeht, so daß er praktisch eine Verbindungsbrücke zwischen diesen beiden Profilschenkeln 27, 28 sowie eine formschlüssige Sicherung gegen Abziehen des Kantenschutzprofiles 25 vom Tragelement 7 bildet.The edge of each profile leg 23 of the support element 7 is provided with an edge protection profile 25, which is molded directly onto the support element 7 in the same way as the injection molded part 21. Each edge protection profile 25 has a profile crosspiece 26 closely fitting on the longitudinal edge of the associated edge 24, which is formed in one piece with two profile legs 27, 28 which are opposite one another and spaced closely on both sides on the outside and on the inside of the profile leg 23, which are the same or can be of different heights. The profile legs 27, 28 and the profile crossbar 26 have approximately the same thickness, which is approximately in the order of magnitude of the wall thickness of the support element 7. The edge 24 is provided between the profile legs 27, 28 with a continuous row of holes 29 closely spaced along its length, the width or inner diameter of which may be of the order of magnitude of the wall thickness of the support element 7 or the edge protection profile 25. In each hole 29 engages this tightly filling locking pin 30, which is formed in one piece with the edge protection profile 25 and preferably integrally with both ends in both facing inner sides of the two profile legs 27, 28, so that it practically a connecting bridge between these two profile legs 27, 28 and form-fitting securing against pulling off the edge protection profile 25 from the support element 7.
