Description

Die Erfindung betrifft einen Seifen-Spender für Flüssigseifen, mit einer Kolbenpumpe, in deren Zylinderlaufbahn im Bereich der vorderen Seite des Kolbens eine Einlaßöffnung aus einem Seifenspeicher mündet und deren, einen am vorderen Kolbenende offenen Längskanal aufweisender, mit dem vorderen Ende einen Schlitzschieber für die Einlaßöffnung bildender, Kolben weiter hinten eine zur Zylinderwandung führende Mündung des Längskanales aufweist, in deren Bewegungsbereich die Eingangsöffnung eines von der Zylinderlaufbahn ausgehenden Auslaßkanales vorgesehen ist.The invention relates to a soap dispenser for liquid soaps, with a piston pump, in the cylinder track in the region of the front side of the piston an inlet opening from a soap reservoir and whose, having a longitudinal channel open at the front end of the piston, with the front end of a slit slide for the inlet opening forming piston further back has a mouth of the longitudinal channel leading to the cylinder wall, in the range of movement of which the inlet opening of an outlet channel starting from the cylinder raceway is provided.

Seifenspender dieser Art können den Nachteil haben, daß die je Pumphub ausgebrachte Seifenmenge nicht der der jeweiligen Benutzungsart bzw. dem Aufstellungsort angepassten Seifenmenge entspricht.Soap dispensers of this type can have the disadvantage that the amount of soap applied per pump stroke does not correspond to the amount of soap adapted to the respective type of use or the place of installation.

Der Erfindung liegt die Aufgabe zugrunde, einen Seifen-Spender der eingangs genannten Art zu schaffen, welcher auf einfache Weise hinsichtlich der je Pumpenhub austretenden Seifenmenge verstellt werden kann, wobei insbesondere eine Verringerung der je Pumpenhub ausgebrachten Menge möglich sein soll.The invention has for its object to provide a soap dispenser of the type mentioned, which in a simple manner with regard to the amount of soap exiting per pump stroke can be adjusted, in particular a reduction in the amount applied per pump stroke should be possible.

Diese Aufgabe wird bei einem Seifen-Spender der eingangs genannten Art gemäß der Erfindung dadurch gelöst, daß im Bereich des Zylinderdeckels ein etwa in Längsrichtung des Kolbens verstell- und festsetzbarer Mengenregulier-Anschlag für die Kolbeneinheit vorgesehen ist. Es hat sich gezeigt, daß dadurch bei raumsparender kompakter Ausbildung eine sehr genaue Regulierung der je Pumpenhub ausgebrachten Seifenmenge möglich ist.This object is achieved in a soap dispenser of the type mentioned at the outset according to the invention in that a quantity regulating stop which can be adjusted and fixed approximately in the longitudinal direction of the piston is provided for the piston unit in the region of the cylinder cover. It has been shown that this enables very precise regulation of the amount of soap applied per pump stroke with space-saving compact design.

In manchen Fällen ist es vorteilhaft, wenn der Anschlag am Ende des Pumphubes in Anschlagstellung steht, wenn also der Pumphub durch den Anschlag veränderbar begrenzt wird. Stattdessen, vorzugsweise aber zusätzlich hierzu kann es auch sehr vorteilhaft sein, wenn der Anschlag in Ausgangsstellung des Kolbens in Anschlagstellung steht, wenn also der Rückhub veränderbar begrenzt wird. Es hat sich gezeigt, daß bei einer solchen Anschlagausbildung in einer Mittelstellung die maximale Seifenmenge je Pumpenhub ausgebracht wird und durch Verstellen des Anschlages in beiden Richtungen jeweils zunehmend eine Verringerung der je Pumpenhub ausgebrachten Menge erfolgt.In some cases it is advantageous if the stop at the end of the pump stroke is in the stop position, ie if the pump stroke is limited by the stop. Instead of this, but preferably in addition to this, it can also be very advantageous if the stop in the starting position of the piston is in the stop position, that is if the return stroke is variably limited. It has been shown that with such a stop design, the maximum amount of soap per pump stroke is applied in a central position and that the amount applied per pump stroke is increasingly reduced by adjusting the stop in both directions.

Nach einem weiteren Merkmal der Erfindung ist der Anschlag als doppelseitiger Anschlag ausgebildet, so daß ein einziger Anschlag sowohl für die Begrenzung des Pumphubes wie auch für die Begrenzung des Rückhubes geeignet ist und somit die Gesamtlänge des Hubes bei jeder Anschlagstellung gleich ist. Es ist aber auch denkbar, zur Begrenzung des Rückhubes einen gegenüber dem Zylinderdeckel feststehenden Anschlag vorzusehen, so daß dann die Ausgangsstellung des Kolbens stets die gleiche ist.According to a further feature of the invention, the stop is designed as a double-sided stop, so that a single stop is suitable both for the limitation of the pump stroke and for the limitation of the return stroke and thus the total length of the stroke is the same for every stop position. However, it is also conceivable to provide a stop that is fixed relative to the cylinder cover in order to limit the return stroke, so that the initial position of the piston is then always the same.

Bei einer besonders raumsparenden und einfachen Ausbildung ist der Anschlag am Zylinderdeckel gelagert und dem inneren Ende des Anschlages ein Gegenanschlag des Kolbens und/oder dem äußeren Ende ein Gegenanschlag der Handhabe zugeordnet.In a particularly space-saving and simple design, the stop is mounted on the cylinder cover and a counter stop of the piston is assigned to the inner end of the stop and / or a counter stop of the handle is assigned to the outer end.

Ein Gegenanschlag ist zweckmäßig durch einen benachbart zu einer hinteren Kolbendichtung liegenden Anschlagring gebildet, so daß bei einfacher Montage eine direkte Anschlagbelastung der Kolbendichtung vermieden ist.A counterstop is expediently formed by a stop ring lying adjacent to a rear piston seal, so that a direct stop load on the piston seal is avoided with simple assembly.

Zur einfachen Verstellung weist der Anschlag ein Stellgewinde auf, das, um den Anschlag einfach festsetzen zu können, zweckmäßig ein selbsthemmendes Außengewinde ist.For easy adjustment, the stop has an adjusting thread which, in order to be able to simply fix the stop, is expediently a self-locking external thread.

Eine sehr sichere, in der Regel über das hintere Ende des Zylinderdeckels hinausreichende Führung des Kolbens wird erreicht, wenn der Anschlag eine das Zwischenstück umgebende Hülse ist, in der das Zwischenstück vorzugsweise verschiebbar geführt ist.A very safe guidance of the piston, which generally extends beyond the rear end of the cylinder cover, is achieved if the stop is a sleeve surrounding the intermediate piece, in which the intermediate piece is preferably displaceably guided.

Zur weiteren Vereinfachung der Herstellung, der Montage und der Einstellung des Anschlages weist dieser durchgehend gleiche Querschnitte auf, wobei er insbesondere durch einen Rohrabschnitt gebildet ist.To further simplify the manufacture, assembly and setting of the stop, the stop has the same cross-sections throughout, it being in particular formed by a pipe section.

Es ist denkbar, das Zwischenstück einstückig mit dem Kolben und/oder der Handhabe auszubilden. Zur einfachen Montage und Wartung der Kolbenpumpe ist es jedoch vorteilhaft, wenn das Zwischenstück lösbar am Kolben befestigt ist, wobei vorzugsweise zwischen das hinter Ende des Kolbens und eine Schulter des Zwischenstückes eine Kolbendichtung und/oder ein Gegenanschlag eingespannt ist.It is conceivable to form the intermediate piece in one piece with the piston and / or the handle. For simple assembly and maintenance of the piston pump, however, it is advantageous if the intermediate piece is detachably attached to the piston, a piston seal and / or a counterstop being preferably clamped between the rear end of the piston and a shoulder of the intermediate piece.

The invention is explained in more detail below with further details with reference to the embodiment shown in the drawings. They are shown in
  • 1 is a soap dispenser according to the invention in vertical axial section and in the starting position,
  • 2 the soap dispenser in a representation according to FIG. 1, but at the end of the pump stroke,
  • Fig. 3 shows the piston unit of the soap dispenser according to Figures 1 and 2 in an enlarged view.

Wie die Figuren 1 bis 3 zeigen weist ein erfindungsgemäßer Seifen-Spender 1 ein Gehäuse 2 auf, das im oberen Bereich einen im wesentlichen zylindrischen, flachen Seifenspeicher 3 bildet. Der obere Stirndeckel 4 des topfförmigen Seifenspeichers 3 weist ein in dessen Mittelachse liegendes Innengewinde 5 auf, in das der entsprechend gestaltete Hals 6 einer Vorratsflasche 7 für Flüssigseife kopfstehend derart eingeschraubt werden kann, daß die Halsöffnung in den Seifenspeicher 3 mündet.As shown in FIGS. 1 to 3, a soap dispenser 1 according to the invention has a housing 2, which forms an essentially cylindrical, flat soap store 3 in the upper region. The upper end cover 4 of the pot-shaped soap store 3 has an internal thread 5 lying in its central axis, into which the appropriately designed neck 6 of a storage bottle 7 for liquid soap can be screwed upside down in such a way that the neck opening opens into the soap store 3.

In die untere Stirnwand des Seifenspeichers 3 ist der einstückig mit diesem ausgebildete Zylinder 8 einer Kolbenpumpe 10 eingeformt, die in einer Axialebene des Seifenspeichers 3 derart liegt, daß ihre Mittelachse die Mittelachse des Seifenspeichers 3 rechtwinklig schneidet.In the lower end wall of the soap reservoir 3, the cylinder 8 formed integrally therewith is one Piston pump 10 is molded in, which lies in an axial plane of the soap reservoir 3 such that its central axis intersects the central axis of the soap reservoir 3 at a right angle.

In der Zylinderlaufbahn 11 des Zylinders 8 ist ein Kolben 9 verschiebbar geführt, der an seinem vorderen Ende und bis zu seiner vorderen Stirnfläche als Paßzylinder ausgebildet und dadurch dichtschließend an der Zylinderlaufbahn 11 geführt ist. Hinter dem Paßzylinder weist der Kolben 9 einen im Durchmesser reduzierten Abschnitt 12 auf, hinter dem sich eine weitere Kolbendichtung 13 anschließt. Diese Kolbendichtung 13 liegt mit zwei Ringlippen dichtend und gleitbar an der Zylinderlaufbahn 11 an. An das hintere Ende des Kolbens 9 schließt sich ein beispielsweise zylindrisches Zwischenstück 14 an, das durch einen Zylinderdeckel 15 am hinteren Ende des Zylinders 8 aus diesem herausgeführt ist und an seinem äußeren Ende eine Handhabe 16 in Form eines Druckknopfes trägt.A piston 9 is displaceably guided in the cylinder race 11 of the cylinder 8, which piston is designed as a fitting cylinder at its front end and up to its front end face and is thus guided in a tight-fitting manner on the cylinder race 11. Behind the fitting cylinder, the piston 9 has a reduced diameter section 12, behind which a further piston seal 13 is connected. This piston seal 13 rests with two ring lips sealingly and slidably against the cylinder race 11. At the rear end of the piston 9 is connected, for example, a cylindrical intermediate piece 14, which is led out of the cylinder 8 through a cylinder cover 15 at the rear end and carries a handle 16 in the form of a push button at its outer end.

Der Kolben 9 ist durch hülsenförmige Ausbildung mit einem von seinem vorderen Ende ausgehenden, in seiner Mittelachse liegenden Längskanal 17 versehen, der bis in den Abschnitt 12 reicht. Am Obergang zwischen dem Kolben 9 und dem Abschnitt 12 sind im Abschnitt 12 zwei diametral liegende Querbohrungen vorgesehen, welche Mündungen 18 zu dem Ringspalt 19 bilden, welcher durch die Zylinderlaufbahn 11 und den Abschnitt 12 begrenzt ist. Die Mündungen 18 stellen den hinteren Austritt des Längskanales 17 dar. Der mit dem Abschnitt 12 einstückig ausgebildete Kolben 9 ist durch einen gegenüber dem Zwischenstück 14 gesonderten Bauteil gebildet, wobei die beiden Bauteile mit einer in ihrer Achse liegenden Schraube 20 lösbar gegeneinander verspannt sind. Der Kopf der Schraube liegt am Grund des Längskanales 17 derart,daß erdie Mündungen 18 frei läßt, wobei der Gewindeschaft der Schraube 20 in einen im Durchmesser reduzierten Endabschnitt des Zwischenstückes 14 eingreift, der zentriert in eine entsprechende Sacklochbohrung am hinteren Ende des Abschnittes 12 eingreift. Zwischen die hintere Stirnschulter 21 des Abschnittes 12 des Kolbens 9 und die an den vorderen Endabschnitt des Zwischenstückes 14 anschließende Ring-Schulter 22 ist die Kolbendichtung 13 eingespannt. Die Kolbendichtung liegt dabei an der Stirnschulter 21 unmittelbar an und ist an der Schulter 22 unter Zwischenlage eines ringscheibenförmigen Gegenanschlages 23 abgestützt, wobei dieser Gegenanschlag 23 einen Außendurchmesser aufweist, der etwa gleich demjenigen des Abschnittes 12 ist. In den Längskanal 17 greift des weiteren eine Rückstellfeder 24 in Form einer Schraubendruckfeder ein, deren eines Ende am Kopf der Schraube 20 anliegt und deren anderes Ende an der geschlossenen vorderen Stirnwand 25 des Zylinders 8 unter Vorspannung abgestützt ist. An der Innenseite dieser Stirnwand 25 ist ein kegelförmiger Zentriervorsprung 26 vorgesehen, durch welchen das zugehörige Ende der Rückstellfeder 24 auf die Achse des Zylinders 8 dadurch ausgerichtet bleibt, daß dieser Zentriervorsprung 26 in dieses Ende der Rückstellfeder 24 eingreift. Die Rückstellfeder 24 steht ständig unter Vorspannung.The piston 9 is provided with a sleeve-shaped design with a longitudinal channel 17, which extends from its front end and lies in its central axis and extends into section 12. At the transition between the piston 9 and the section 12, two diametrically located transverse bores are provided in the section 12, which form openings 18 to the annular gap 19, which is delimited by the cylinder raceway 11 and the section 12. The orifices 18 represent the rear exit of the longitudinal channel 17. The piston 9, which is formed in one piece with the section 12, is formed by a component separate from the intermediate piece 14, the two components being releasably braced against one another by a screw 20 lying in their axis. The head of the screw lies at the bottom of the longitudinal channel 17 such that it leaves the mouths 18 free, the threaded shaft of the screw 20 engages in a reduced-diameter end portion of the intermediate piece 14, which engages centered in a corresponding blind hole at the rear end of the section 12. The piston seal 13 is clamped between the rear end shoulder 21 of the section 12 of the piston 9 and the ring shoulder 22 adjoining the front end section of the intermediate piece 14. The piston seal lies directly on the forehead shoulder 21 and is supported on the shoulder 22 with the interposition of an annular disk-shaped counter stop 23, this counter stop 23 having an outer diameter which is approximately equal to that of section 12. In the longitudinal channel 17 also engages a return spring 24 in the form of a helical compression spring, one end of which rests against the head of the screw 20 and the other end of which is pretensioned on the closed front end wall 25 of the cylinder 8. On the inside of this end wall 25, a conical centering projection 26 is provided, through which the associated end of the return spring 24 remains aligned with the axis of the cylinder 8 in that this centering projection 26 engages in this end of the return spring 24. The return spring 24 is constantly under tension.

Mit verhältnismäßig geringem Abstand benachbart zum vorderen Ende des in Ausgangsstellung befindlichen Kolbens 9 ist im Zylinder 8, der gleichzeitig den zugehörigen Abschnitt der Bodenwand des Seifenspeichers 3 bildet, eine Einlaßöffnung 27 vorgesehen, die als Obertrittsöffnung zwischen dem Seifenspeicher 3 und dem vor dem Kolben 9 liegenden Zylinderraum 28 dient. Die in der Ebene der vorderen Stirnfläche liegende äußere Ringkante des Kolbens 9 bildet einen Schlitzschieber 29, welcher beim Vorschieben des Kolbens 9 die Einlaßöffnung 27 verschließt, so daß die im Zylinderraum 28 befindliche Flüssigseife beim weiteren Vorschub des Kolbens 9 nur noch durch den Längskanal 17 und die Mündungen 18 in den Rinrgspalt 19 verdrängt werden kann.At a relatively small distance adjacent to the front end of the piston 9 in the starting position, an inlet opening 27 is provided in the cylinder 8, which at the same time forms the associated section of the bottom wall of the soap reservoir 3, which acts as an overflow opening between the soap reservoir 3 and the one in front of the piston 9 Cylinder chamber 28 is used. The outer ring edge lying in the plane of the front face of the piston 9 forms a slot slide 29, which closes the inlet opening 27 when the piston 9 is advanced so that the liquid soap in the cylinder space 28 can only be displaced by the longitudinal channel 17 and the orifices 18 into the annular gap 19 when the piston 9 is advanced further .

Unmittelbar hinter dem in Ausgangsstellung befindlichen Kolben 9 und daher in das vordere Ende des Ringspaltes 19 mündet die Eingangsöffnung 30 eines Auslaßkanales 31 für die Flüssigseife, welcher durch einen Austragnippel an der Unterseite-des Zylinders 8 gebildet ist. Der Austragnippel 32 ist schräg nach unten zur Vorderseite des Seifen-Spenders 1 hin geneigt und weist in seinem Inneren ein im Auslaßkanal 31 liegendes Rückschlagventil 33 in Form eines federbelastenden Kugelventiles auf, das bei Oberdruck in Austragrichtung öffnet. Bei der beschriebenen Verdrängung der Flüssigseife in den Ringspalt 19 tritt die Flüssigseife durch die Mündung 30 unter öffnung des Rückschlagventiles 33 aus dem Austragnippel 32 aus.Immediately behind the piston 9 in the starting position and therefore in the front end of the annular gap 19, the inlet opening 30 of an outlet channel 31 for the liquid soap opens, which is formed by a discharge nipple on the underside of the cylinder 8. The discharge nipple 32 is inclined downwards towards the front of the soap dispenser 1 and has in its interior a non-return valve 33 in the outlet channel 31 in the form of a spring-loaded ball valve which opens in the discharge direction at top pressure. When the liquid soap is displaced into the annular gap 19 as described, the liquid soap emerges from the discharge nipple 32 through the mouth 30 while opening the check valve 33.

Im Zylinderdeckel 15 ist ein hülsenförmiger Mengenregulier-Anschlag 34 mit Außengewinde 35 geführt, der in der Achse des Kolbens liegt, in dessen Innenumfang das Zwischenstück 14 gleitbar geführt ist und dessen Außengewinde 35 in ein entsprechendes Innengewinde im Zylinderdeckel 15 eingreift. Der Außendurchmesser des Anschlages 34 ist nur geringfügig kleiner als der Durchmesser der Zylinderlaufbahn 11, wobei der Kerndurchmesser des Außengewindes 35 geringfügig größer als der Gegenanschlag 23 ist. Der Gegenanschlag 23 ist der inneren Endfläche 36 des Anschlages 34 zugeordnet, während dessen äußerer, ringförmiger Endfläche 37 ein am Zwischenstück 14 vorgesehener, innerhalb der Handhabe 16 liegender ringförmiger Gegenanschlag 38 zugeordnet sein kann. Wie Figur 3 zeigt,umfasst die Kolbeneinheit 39 den Kolben 9, den Abschnitt 12, die Kolbendichtung 13, den Gegenanschlag 23, das Zwischenstück 14 und die Handhabe 16, wobei die Kolbeneinheit mit dem Zylinderdeckel 15 und dem Anschlag 34 eine Baueinheit bildet.In the cylinder cover 15, a sleeve-shaped quantity regulating stop 34 with an external thread 35 is guided, which lies in the axis of the piston, in the inner circumference of which the intermediate piece 14 is slidably guided and whose external thread 35 engages in a corresponding internal thread in the cylinder cover 15. The outside diameter of the stop 34 is only slightly smaller than the diameter of the cylinder race 11, the core diameter of the outside thread 35 being slightly larger than the counter-stop 23. The counter-stop 23 is assigned to the inner end surface 36 of the stop 34, during the outer, annular end surface 37 of which is provided on the intermediate piece 14 and lies within the handle 16 Counterstop 38 can be assigned. As FIG. 3 shows, the piston unit 39 comprises the piston 9, the section 12, the piston seal 13, the counter stop 23, the intermediate piece 14 and the handle 16, the piston unit forming a structural unit with the cylinder cover 15 and the stop 34.

Durch den Anschlag 34 kann sowohl die Lage der Ausgangsstellung des Kolbens 9 gegenüber dem Zylinder 8 wie auch dessen Endstellung am Ende des Pumphubes gemäß Figur 2 festgelegt und somit verändert werden. Das Außengewinde 35 ist als selbsthemmendes Gewinde ausgebildet, so daß gesonderte Mittel zum Festsetzen des Anschlages 34 in der jeweils eingestellten Stellung nicht erforderlich sind.The stop 34 allows both the position of the initial position of the piston 9 relative to the cylinder 8 and its end position at the end of the pump stroke according to FIG. 2 to be determined and thus changed. The external thread 35 is designed as a self-locking thread, so that separate means for fixing the stop 34 in the respectively set position are not required.
