Abstract

The deflector distributes the compressed-air by means of a rotary plate (2). Two or more sockets (3a,3c) are formed in its underside, and into which the compressed air can flow if desired via the pressure chamber (1e) inside the deflector. These fit onto mating bosses (4,5) formed in the mat (6). In the top of the deflector there can be a further mounting (1a) for the hose union from a fan connected to the pressure chamber. A stop (1d) inside the mounting limits the depth for which the hose can be inserted.

Description

Die Erfindung betrifft eine abnehmbare Luftweiche für Sprudelmatten, bei welcher die Verteilung der Druckluft durch einen Drehschieber erfolgt.The invention relates to a removable air switch for bubble mats, where the distribution of the compressed air by a Rotary valve takes place.

Schon bald nach der Einführung des Luftsprudelmassagebades war man bestrebt, die Sprudelmatte in mehrere möglichst anatomisch geformte Druckräume zu unterteilen und den Luftstrom vom Gebläse durch Luftweichen dorthin zu lenken. Für diese Luftweichen gibt es mittlerweile eine ganze Reihe technischer Lösungen. So offenbart die DE-PS 34 03 735 eine Luftweiche, bei der die Druckluft je nach Stellung einer Drehkulisse auf die beiden seitlichen Kanäle für "Mattenflächen" oder den mittigen Kanal für die "Wirbelsäulenzeile" geschaltet wird. Die Luftweiche ist erkennbar fest in die Sprudelmatte integriert und kann nicht von dieser gelöst, aber auch nicht demontiert werden. Außerdem sind für die Stellung "Mittelzeile" zwei Öffnungen, nämlich die der "Mattenfläche" abzudecken, was an die Verarbeitungspräzision gewisse Anforderungen stellt.Was soon after the introduction of the bubble bath one endeavors to form the bubble mat into several as anatomically as possible to divide shaped pressure chambers and the airflow from the blower to steer there by air switches. For these air switches there are now a whole range of technical solutions. For example, DE-PS 34 03 735 discloses an air switch in which the compressed air depending on the position of a rotating link on the two lateral channels for "mat surfaces" or the central channel is switched for the "spine row". The air switch is clearly integrated into the bubble mat and cannot detached from it, but also not disassembled. Moreover are two openings for the "center line" position, namely the to cover the "mat surface", which affects the processing precision has certain requirements.

Aufgabe der Erfindung ist die Schaffung einer Luftweiche, die von der Sprudelmatte einfach und vorzugsweise ohne Werkzeug abgenommen werden kann. The object of the invention is to provide an air switch which simply and preferably removed from the bubble mat without tools can be.

Diese Aufgabe wird dadurch gelöst, daß die Luftweiche über zumindest zwei Konusaufnahmen an ihrer Unterseite verfügt, in welche die Druckluft über den Weichendruckraum im Innern der Luftweiche wahlweise strömen kann, und die auf entsprechend angeordneten Stutzen, die in die Sprudelmatte eingearbeitet sind, passen.This object is achieved in that the air switch at least has two cone receptacles on its underside which the compressed air over the switch pressure space inside the The air switch can flow selectively, and that can be arranged accordingly Nozzles that are incorporated into the bubble mat, fit.

Im Prinzip handelt es sich bei der erfindungsgemäßen Luftweiche um eine funktionelle Brücke zwischen zwei in die Sprudelmatte eingearbeiteten Stutzen für getrennt zu beaufschlagende Sprudelbereiche. Sie werden von Konusaufnahmen im Unterteil der Luftweiche umfaßt, die sich in den von ihr umschlossenen Weichendruckraum öffnen. Diese Öffnungen werden bei Betätigung eines Drehschiebers wahlweise zugedeckt und freigegeben. In der Mittelstellung des Drehschiebers können demzufolge beide Öffnungen näherungsweise zur Hälfte abgedeckt sein.In principle, it is the air switch according to the invention a functional bridge between two in the bubble mat built-in nozzle for separately charged whirlpool areas. They are made of cone shots in the lower part of the Includes air switch, which is in the switch pressure space enclosed by it to open. These openings are opened when a Rotary valve optionally covered and released. In the The middle position of the rotary valve can therefore both openings approximately half covered.

Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous developments of the invention emerge from the subclaims forth.

In einer bevorzugten Ausgestaltung besitzt das Oberteil der Luftweiche eine z.B. konische Aufnahme für den Schlauchanschluß vom Gebläse, evtl. mit einem Anschlag für denselben. Die auf diesem Wege ankommende Druckluft kann zweckmäßigerweise entweder voll zu einem der Stutzen geleitet oder - je nach Stellung des Drehschiebers - im Verhältnis der Öffnungsflächen aufgeteilt werden. Es gibt dann keine Stellung, in der die Luftverteilung gedrosselt wäre; die Eigenlüftung des Gebläses ist demnach voll gewährleistet. In a preferred embodiment, the upper part of the Air switch e.g. conical receptacle for the hose connection from the blower, possibly with a stop for the same. The on Compressed air arriving this way can expediently either fully directed to one of the sockets or - depending on the position of the rotary valve - divided in the ratio of the opening areas become. Then there is no position in which the air distribution would be throttled; The fan is therefore self-ventilated fully guaranteed.

Ebenso möglich sind aber auch Ausführungsarten ohne direkte Schlaucheinspeisung, z.B. bei solchen mit mehr als zwei von der Luftweiche zusammengefaßten Stutzen. Einer dieser Stutzen kann in diesem Fall die Druckluft liefern, die dann auf die anderen Stutzen - und damit Sprudelbereiche - je nach Stellung des Drehschiebers aufgeteilt wird.However, designs without direct are also possible Hose feed, e.g. for those with more than two of the Air switch combined nozzle. One of these sockets can in this case supply the compressed air, which is then to the others Nozzles - and therefore whirlpool areas - depending on the position of the Rotary valve is divided.

Selbstverständlich sind auch Variationen des Sprudelbildes dadurch möglich, daß die Luftweiche von z.B. 5 möglichen Stutzen jeweils nur 3 zusammenfaßt, z.B. 1 - 3 oder aber 3 - 5, mit dem Ergebnis, daß beispielsweise nur die linke oder die rechte Mattenfläche sprudeln. Denkbar sind natürlich auch mehrere Luftweichen auf einer Sprudelmatte.Of course there are also variations of the sparkling image possible that the air switch from e.g. 5 possible sockets groups only 3 at a time, e.g. 1 - 3 or 3 - 5, with the result that, for example, only the left or the right Bubble the mat surface. Of course, several are also conceivable Air switches on a bubble mat.

Wie schon angedeutet, sollte die Luftweiche vorzugsweise aus zwei Teilen aufgebaut sein, die über eine waagrecht umlaufende Nutverbindung mit Dichtung gegeneinander verspannt sind, z.B. durch eine Schraubverbindung. Diese kann, auch vom Anwender, bei Bedarf gelöst werden, z.B. zum Zwecke der Reinigung.As already indicated, the air switch should preferably be off be built in two parts, one horizontally revolving Groove connection with seal are clamped against each other, e.g. through a screw connection. This can, also by the user, be solved if necessary, e.g. for cleaning purposes.

Das ganze Teil sollte so gestaltet sein, daß es weder eine Stolperfalle in der Badewanne bildet noch durch scharfe Ecken, Kanten oder Absätze den Anwender gefährden kann.The whole part should be designed so that it is neither a Trip hazard in the bathtub is still formed by sharp corners, Edges or shoulders can endanger the user.

Der Drehschieber wird betätigt per Hand, Zehen oder Ferse, zweckmäßigerweise durch einen ergonomisch geformten Wählhebel mit angeformter Griffnase. Diese kann nach vorne heruntergezogen sein, damit sie vom bedienenden Körperteil besser erfaßt wird.The rotary valve is operated by hand, toe or heel, expediently by an ergonomically shaped selector lever with molded handle. This can be pulled down to the front so that it is better grasped by the operating body part becomes.

Der Wählhebel läuft vorzugsweise auf einer durch Begrenzungskanten im Oberteil V-förmig begrenzten Fläche. Liegt er an einer dieser Begrenzungskanten an, verschließt die an der Achse angebrachte Drehkulisse gerade eine der Öffnungen vollständig. Der dichte Abschluß kann dabei von Stützzapfen gewährleistet sein, die die Drehkulisse in der jeweiligen Endstellung gegen die flachrandige Öffnung drücken.The selector lever preferably runs on one through boundary edges V-shaped area in the upper part. Is it due to one this boundary edges closes the on the axis attached rotating backdrop just one of the openings completely. The tight seal can be ensured by support pins be against the rotating backdrop in the respective end position press the flat-edged opening.

Die oben erwähnten Stutzen sind zweckmäßigerweise in die Oberfolie der Sprudelmatte eingearbeitet und stützen sich gegen die Unterfolie mittels Stegen ab. Diese weisen Durchbrüche für die Druckluft auf, so daß auch bei Belastung der Stutzen die Luftzufuhr nie abgedrosselt werden kann.The above-mentioned nozzles are expediently in the top film the bubble mat incorporated and support against the Remove the bottom film using webs. These have breakthroughs for the Compressed air, so that the air supply even when the nozzle is loaded can never be throttled.

Die sich bei verschiedenen Ausführungsbeispielen einstellenden Vorteile der vorgeschlagenen Luftweiche sind unter anderem also folgende:The resultant in different embodiments The advantages of the proposed air switch are among other things the following:

Durch die Tatsache, daß die Luftweiche von der Sprudelmatte abnehmbar ist, kann sie bei Defekten leicht ausgetauscht werden. Bei konventioneller Bauweise ist im Falle eines Fehlers z.B. in der Luftweiche stets die ganze Matte unbrauchbar. Bei einer entsprechenden Ausführung ist die Sprudelmatte sogar ohne Luftweiche eingeschränkt einsatzfähig: Es sprudelt jeweils der Teil, in dessen Stutzen der Schlauchanschluß direkt eingesteckt wurde. Die Luftweiche selbst ist ebenfalls leicht zerlegbar; sie kann folglich vom Benutzer gereinigt und ggfls. repariert werden. Das ist in Zeiten schwindender "Wegwerfmentalität" zweifellos ein Vorteil. Dazu trägt auch bei, daß die Luftweiche sehr einfach, robust und auch kostengünstig aufgebaut ist. Auch ist die Konstruktion gegen allfällige Verschmutzungen relativ unempfindlich, da sie durch die tangentiale Schleifbewegung selbstreinigend arbeitet. Sehr komfortabel ist der Umstand zu werten, daß die Luftweiche leicht auch per Fuß (Zehen, Ferse) zu verstellen ist.Due to the fact that the air switch can be removed from the bubble mat it can be easily replaced in the event of defects. In the case of a conventional design, in the event of a fault, e.g. in the air switch always useless the entire mat. At a Corresponding design is the bubble mat even without air switch Restricted use: The bubbles up Part in the socket of which the hose connection is inserted directly has been. The air switch itself can also be easily dismantled; it can therefore be cleaned by the user and if necessary. repaired become. This is in times of waning "disposable mentality" undoubtedly an advantage. This also helps that the air switch is very simple, robust and also inexpensive. Also the construction against any contamination is relative insensitive because of the tangential grinding movement works self-cleaning. The circumstance is very comfortable too evaluate that the air switch can also be easily carried by foot (toes, heel) is to be adjusted.

Beide Konusaufnahmen 3a, 3c besitzen Öffnungen (3b, 3d) in den vom Oberteil 1 und Unterteil 3 umschlossenen Weichendruckraum le im Innern der Luftweiche. Diese Öffnungen 3b, 3d werden in Abhängigkeit von der Stellung eines Drehschiebers 2 abwechselnd vollständig oder teilweise von einer Drehkulisse 2d abgedeckt. Unterstützend dabei wirkt ein in jeder Endstellung Druck auf die Drehkulisse 2d ausübender Stützzapfen 1c.While the upper part 1 a recording la with stop ld for the Hose connection of the coming from the fan, not shown Hose has a first cone seat in the lower part 3a for a first nozzle 4 of the bubble mat 6 and one second cone holder 3c for a second nozzle 5 of the bubble mat let in. Both cone receptacles 3a, 3c have openings (3b, 3d) in those enclosed by the upper part 1 and lower part 3 Switch pressure room le inside the air switch. These openings 3b, 3d are depending on the position of a Rotary slide valve 2 alternately completely or partially by one Rotating backdrop covered 2d. An in supports this each end position exerting pressure on the rotating link 2d Support pin 1c.

Die Drehkulisse 2d ist Teil des Drehschiebers 2, der außerdem aus einer in einem Lager 1b laufenden Achse 2c und einem außenliegenden Wählhebel 2a besteht. Dieser verfügt über eine nach vorne/unten heruntergezogene Griffnase 2b. Die Stutzen 4, 5 sind zweckmäßigerweise in die Oberfolie 6a der Sprudelmatte 6 eingearbeitet und stützen sich gegen die Unterfolie 6b der Sprudelmatte über Stege 4a mit Durchbrüchen ab.The rotating link 2d is part of the rotary valve 2, which also from an axis 2c running in a bearing 1b and an external one Selector lever 2a exists. This has an after Front / bottom handle tab 2b. The sockets 4, 5 are expediently in the top film 6a of the bubble mat 6 incorporated and are supported against the bottom film 6b Bubble mat over webs 4a with openings.

Figur 2 ist eine Draufsicht auf die Unterseite des Unterteils 3. In dieser Perspektive sichtbar sind Schraubverbindungen 3f durch die das Oberteil 1 und das Unterteil 3 aneinander festgelegt sind. Der Wählhebel 2a ist in Mittelstellung gestrichelt eingezeichnet.Figure 2 is a top view of the underside of the base 3. Screw connections 3f are visible in this perspective through which the upper part 1 and the lower part 3 are fixed to each other are. The selector lever 2a is dashed in the middle position drawn.

Figur 3 verdeutlicht im Querschnitt die Verbindung von Oberteil 1 zu Unterteil 3 durch die Nutverbindung 3e und die zusätzliche Schraubverbindung 3f. Die Druckluft strömt zunächst in die Aufnahme la, dann in den Weichendruckraum le und schließlich durch eine Öffnung, in diesem Falle 3b, letztlich in den zugehörigen Stutzen (nicht dargestellt) der Sprudelmatte 6.Figure 3 illustrates in cross section the connection of the upper part 1 to lower part 3 through the groove connection 3e and the additional Screw connection 3f. The compressed air first flows into the receptacle la, then into the switch printing room le and finally through an opening, in this case 3b, ultimately in the associated Neck (not shown) of the bubble mat 6.

Die Draufsicht auf das Oberteil 1 in Figur 4 vervollständigt die Erläuterungen dieses Ausführungsbeispiels. Neben der Schraubverbindung 3f sind hier erkennbar vor allem der Anschlag 1d für den Schlauchanschluß in der Aufnahme la sowie verschiedene Stellungen des Wählhebels 2a und der Drehkulisse 2d. Steht der Wählhebel 2a z.B. nach "links unten", so befindet sich die Drehkulisse 2d in einer Position ca. zwischen "3 und 6 Uhr", wobei sie die Öffnung 3b der ersten Konusaufnahme 3a abdeckt und die Öffnung 3d der zweiten Konusaufnahme 3c freigibt. Somit sprudelt die "Wirbelsäulenzeile"; die "Mattenfläche" ruht. Ebenfalls eingezeichnet sind Begrenzungskanten lf, die dem Wählhebel 2a als Anschlag dienen.The top view of the upper part 1 in FIG. 4 is completed the explanations of this embodiment. In addition to the The screw connection 3f can be seen here above all the stop 1d for the hose connection in the receptacle la and various Positions of the selector lever 2a and the rotating link 2d. Stands the selector lever 2a e.g. to "bottom left", there is the Rotating scenery 2d in a position between "3 and 6 o'clock", covering the opening 3b of the first cone receptacle 3a and opens the opening 3d of the second cone holder 3c. Consequently bubbles the "spine row"; the "mat surface" rests. Also delineated are boundary edges lf that Selector lever 2a serve as a stop.

Die beispielsgemäße Luftweiche verfügt also über zumindest zwei Konusaufnahmen 3a, 3c an ihrer Unterseite, in welche die vom Gebläse über einen Schlauch herangeführte Druckluft über den Weichendruckraum 1e im Innern der Luftweiche wahlweise strömen kann und die auf entsprechend angeordneten Stutzen 4, 5, die in die Sprudelmatte 6 eingearbeitet sind, passen. Zweckmäßigerweise wird die Luftweiche auf die Stutzen 4, 5 lediglich aufgesteckt, wobei durch die konische Ausgestaltung eine rein kraftschlüssige Klemmung erfolgt, die einen sicheren Halt der Luftweiche gewährleistet und eine Montage und Demontage ohne Werkzeug ermöglicht.The exemplary air diverter thus has at least two Cone receptacles 3a, 3c on their underside, in which the from Blower fed compressed air via a hose over the Flow the switch pressure chamber 1e inside the air switch either can and on appropriately arranged nozzle 4, 5, which in the bubble mat 6 are incorporated, fit. Conveniently the air switch is simply plugged onto the sockets 4, 5, with the conical design a purely frictional Clamping takes place, which holds the air switch securely guaranteed and assembly and disassembly without tools enables.

An der Oberseite der Luftweiche ist eine weitere Aufnahme la für den Schlauchanschluß vom Gebläse eingearbeitet, die mit dem Weichendruckraum le in Verbindung steht.At the top of the air switch there is another photo la for the hose connection from the blower, which is integrated with the Switch pressure space le is connected.

Das Gebläse der Luftweiche ist zweigeteilt und umfaßt ein Oberteil 1 und ein Unterteil 3, die über eine waagrecht verlaufende Nutverbindung 3e mit durchgehender Dichtung unter Vermittlung einer lösbaren Schraubverbindung 3 gegeneinander verspannt sind. Die beiden Konusaufnahmen 3a, 3c sind im Unterteil 3 angeordnet und stehen mit dem Weichendruckraum le über Öffnungen 3b, 3d in Verbindung, die Richtung Weichendruckraum le zweckmäßigerweise flachrandig ausgeführt sind und auf derselben Höhe liegen.The fan of the air switch is divided into two parts and includes an upper part 1 and a lower part 3, which runs over a horizontal Groove connection 3e with continuous seal with mediation a detachable screw connection 3 braced against each other are. The two cone receptacles 3a, 3c are arranged in the lower part 3 and stand with the switch printing space le over openings 3b, 3d in connection, the direction of switch pressure space le expediently are flat-edged and at the same height lie.

Oberteil 1 und Unterteil 3 verfügen über eine glatte, abgerundete, ergonomisch gestaltete Oberfläche ohne scharfe Absätze und Kanten, so daß der Anwender nicht Gefahr läuft, sich zu verletzen.Upper part 1 and lower part 3 have a smooth, rounded, ergonomically designed surface without sharp heels and edges so that the user does not run the risk of becoming too hurt.

Das Oberteil 1 weist ein senkrecht verlaufendes Lager 1b für die Achsen 2c des Drehschiebers 2 auf, das so angeordnet ist, daß die untere an der Achse 2c befindliche Drehkulisse 2d in Extremstellungen ihres Schaltweges gerade eine der Öffnungen 3b, 3d dicht abdeckt und die jeweils andere freigibt. Der Schaltweg des Drehschiebers 2 ist durch die in das Oberteil 1 eingearbeiteten Begrenzungskanten 1f, die näherungsweise ein nach außen offenes "V" bilden, vorzugsweise in der Weise definiert, daß in den Extremstellungen der Drehkulisse 2d der an der Achse 2c angeformte Wählhebel 2a gerade an diesen Begrenzungskanten 1f anliegt. An der Innenseite des Oberteils 1 ist jeweils ein Stützzapfen 1c zum Andrücken der Drehkulisse 2d gegen die Öffnungen 3b, 3d angeformt.The upper part 1 has a vertical bearing 1b for the axes 2c of the rotary valve 2, which is arranged so that the lower rotating link 2d located on the axis 2c in Extreme positions of their switching path just one of the openings 3b, 3d tightly covers and the other releases. The Switching travel of the rotary valve 2 is through the in the upper part 1st incorporated boundary edges 1f, approximately one form "V" open to the outside, preferably defined in such a way that in the extreme positions of the rotating link 2d Selector lever 2a formed on axis 2c just at these boundary edges 1f is present. On the inside of the upper part 1 is each a support pin 1c for pressing the rotating link 2d against the openings 3b, 3d formed.

Die in die Oberfolie 6a der Sprudelmatte 6 eingearbeiteten Stutzen 4, 5 stützen sich über mit Durchbrüchen versehene Stege 4a, 5a im Innern der Sprudelmatte 6 gegen die Unterfolie 6b ab, so daß die Druckluft aus denselben ungehindert in den im Innern der Sprudelmatte 6 definierten Mattendruckraum 7 strömen kann.The worked into the top sheet 6a of the bubble mat 6 Sockets 4, 5 are supported by webs with openings 4a, 5a in the interior of the bubble mat 6 against the lower film 6b, so that the compressed air from them unhindered in the inside the bubble mat 6 can flow defined mat pressure space 7.

Bei der Luftweiche handelt es sich um eine funktionelle Brücke zwischen zwei in die Sprudelmatte 6 eingearbeitete Stutzen (4, 5) für getrennt zu beaufschlagende Sprudelbereiche. Sie werden von Konusaufnahmen 3a, 3c im Unterteil der Luftweiche umfaßt, die sich in den von ihr umschlossenen Weichendruckraum le öffnen. Diese Öffnungen 3b, 3d werden bei Betätigung eines Drehschiebers 2 wahlweise zugedeckt und freigegeben. In der Mittelstellung des Drehschiebers 2 sind demzufolge beide Öffnungen 3b, 3d näherungsweise zur Hälfte abgedeckt. The air switch is a functional bridge between two nozzles incorporated in the bubble mat 6 (4, 5) for whirlpool areas to be charged separately. you will be of cone receptacles 3a, 3c in the lower part of the air switch, that open into the turnout pressure room le enclosed by it. These openings 3b, 3d are when a rotary valve is actuated 2 optionally covered and released. In the middle position of the rotary valve 2 are therefore both openings 3b, 3d approximately covered by half.

Das Oberteil 1 besitzt eine z.B. konische Aufnahme la für den Schlauchanschluß vom Gebläse, evtl. mit einem Anschlag ld für denselben. Die auf diesem Wege ankommende Druckluft wird also entweder voll zu einem der Stutzen 4, 5 geleitet oder - je nach Stellung des Drehschiebers 2 - im Verhältnis der Öffnungsflächen aufgeteilt. Die Luftweiche kann bei Defekten leicht ausgetauscht werden und ist voll zerlegbar. Sie ist einfach und robust gebaut. Durch die tangentiale Schleifbewegung arbeitet sie selbstreinigend. Sie kann bequem auch per Zehen / Fersen bedient werden.The upper part 1 has e.g. conical mount la for the Hose connection from the blower, possibly with a stop ld for the same. The compressed air arriving in this way is thus either fully directed to one of the nozzles 4, 5 or - depending on Position of the rotary valve 2 - in relation to the opening areas divided up. The air switch can be easily replaced in the event of defects and can be fully dismantled. It is simple and robust built. It works through the tangential grinding movement self-cleaning. It can also be operated comfortably by toes / heels become.
