Description
Handspritzpistole für ein Hoc druckreinigungsgerätManual spray gun for a Hoc pressure washer
Die Erfindung betrifft eine Handspritzpistole für ein Hochdruckreinigungsgerät, mit einem Rohrstück aus Kunststoff, welches einen Flüssigkeitskanal, eine Schließeinrichtung, einen Zufuhrbereich für die Flüssigkeit zur Schließeinrichtung sowie einen Bereich des Flüssigkeitskanals stromabwärts der Schließeinrichtung aufweist.The invention relates to a hand-held spray gun for a high-pressure cleaning device, with a pipe section made of plastic, which has a liquid channel, a closing device, a supply area for the liquid to the closing device and an area of the liquid channel downstream of the closing device.
Ein Hochdruckreinigungsgerät besteht im allgemeinen aus einer elektro-/ oder benzinmotorisch angetriebenen Pumpe, mit der Flüssigkeit unter hohen Druck gesetzt und über eine Flüssigkeitsabgabeeinrichtung auf die zu reinigende Oberfläche ausgegeben wird. Die Flüssigkeitsabgabeeinrichtung umfasst oftmals eine Handspritzpiεtole wie eingangs beschrieben.A high-pressure cleaning device generally consists of an electric or gasoline-driven pump with which the liquid is put under high pressure and is dispensed onto the surface to be cleaned via a liquid dispenser. The liquid dispensing device often comprises a manual spray gun as described at the beginning.
Handspritzpistolen dieser Art dienen bei Hochdruckreinigungsgeräten dazu, die Abgabemenge zu regeln, insbesondere den Fluss der Flüssigkeit zu unterbrechen. Beim Schließen der Schließeinrichtung in solchen Handspritzpistolen arbeitet in einigen Fällen die Pumpe des Hochdruσkreinigungsge- rätes weiter und es kann dadurch zu erheblichen Druckanstiegen im Bereich zwischen dem Druckauslas3 der Pumpe dee Hochdruckreinigungsgerätes und der Schließeinrichtung kommen. Dabei entstehen in dem Rohrstück einer solchen Handspritzpistole stromaufwärts der Schließeinrichtung im Zufuhrbereich hohe Druckspitzen, so dass die Gefahr besteht, dass gerade der Zufuhrbereich des Rohrstückes erhöhten Belastungen ausgesetzt ist. Bei einem einstückig aus Kunststoff hergestellten Rohrstück sind also im Bereich der Flüssigkeitsabfuhr stromabwärts der Schließeinrichtung geringere Ansprüche an die Festigkeit des Kunststoffes zu stellen, als im Bereich stromaufwärts der Schließeinrichtung. Um das gesamte Rohrstück einstückig aus Kunststoff herstellen zu können, wäre es deshalb notwendig, dieses Rohrstück aus einem widerstandsfähigeren Kunststoff herzustellen. Dieses würde zu erhöhten Herstellungskosten für die Handspritzpistole führen.Handheld spray guns of this type are used in high-pressure cleaning devices to regulate the delivery quantity, in particular to interrupt the flow of the liquid. When closing the locking device in such hand-held spray guns, the pump of the high-pressure cleaning device continues to operate in some cases and this can result in considerable pressure increases in the area between the pressure outlet of the pump of the high-pressure cleaning device and the locking device. This creates high pressure peaks in the pipe section of such a hand-held spray gun upstream of the locking device in the feed area, so that there is a risk that the feed area of the pipe section in particular is exposed to increased loads. In the case of a piece of pipe which is made in one piece from plastic, lower demands are to be made of the strength of the plastic in the area of the liquid discharge downstream of the locking device than in the area upstream of the locking device. In order to be able to manufacture the entire pipe section in one piece from plastic, it would therefore be necessary to produce this pipe section from a more resistant plastic. This would lead to increased manufacturing costs for the hand spray gun.
Die Aufgabe und das Ziel der Erfindung bestehen darin, eine Handspritzpistole mit einstückigem Rohrstück aus Kunststoff herzustellen, bei der ein kostengünstiger Kunststoff verwendet werden kann.The object and the aim of the invention are to produce a hand-held spray gun with a one-piece tube piece made of plastic, in which an inexpensive plastic can be used.
Zur Lösung dieser Aufgabe wird eine Handspritzpistole mit den Merkmalen des geltenden Anspruchs 1 vorgeschlagen. Dadurch, da3s auf den rohrformigen Zufuhrbereich des zentralen Formteiles eine Hülse aufgeschoben ist, die aus einem widerstandsfähigeren Material besteht als das Rohstück, wird erreicht, dass nicht das gesamte Rohrstück aus dem geforderten widerstandsfähigeren Kunststoff herzustellen ist, sondern dass es ausreicht, das Rohrstück aus einem Kunststoff mit geringerem Widerstand gegen Druckbeanspruchungen herzustellen und es nur in den besonders druckbeanspruchten Bereichen stromaufwärts des Schließventils mit einer zusätzlichen Hülse zu verstärken. Auf diese Weise wird in dem besonders beanspruchten Bereich des Rohrstückes eine ausreichende Festigkeit gegenüber den besonderen Druckbeanspruchungen nach dem Schließen der Schließeinrichtung erreicht. Besonders preiswert lässt sich die Hülse aus einem Kunststoff herstellen. Eine noch höhere Festigkeit bei geringerem Preis ergibt sich, wenn die Hülse aus Metall besteht. Eine besonders lange Haltbarkeit ergibt sich, wenn die Hülse aus rostfreiem Stahl hergestellt wird. Eine Hülse aus Aluminium weist ein besonders geringes Gewicht bei hoher Festigkeit auf. Eine besonders einfache Montage der erfindungsgemäßen Hand- spritzpistole ergibt sich, wenn auf dem Zufuhrbereich des Rohstückes am Umfang Vorsprünge zur Halterung der aufgeschobenen Hülse vorgesehen sind. Besonders einfach lässt sich eine Halterung vorsehen, wenn der Außendurchmesser des rohrformigen Zufuhrbereichs von der Zufuhrseite her zunimmt, so dass die Hülse aufgeschoben und in ihrer Endstellung verklemmt werden kann. Ein einfaches Aufschieben bei der Montage ergibt sich, wenn auf dem Umfang des rohrf rmigen Zufuhrbereichs abschnittweise vorstehende Längsrippen vorgesehen sind, so dass die aufgeschobene Hülse durch Verklemmung mit diesen Rippen gehalten wird.To solve this problem, a hand spray gun with the features of the current claim 1 is proposed. As a result of the fact that a sleeve, which consists of a more resistant material than the raw piece, is pushed onto the tubular feed area of the central molded part, it is achieved that the entire tubular piece is not to be produced from the required more resistant plastic, but that it is sufficient to make the tubular piece from one To produce plastic with less resistance to pressure loads and to reinforce it with an additional sleeve only in the particularly pressure-stressed areas upstream of the closing valve. In this way, sufficient strength is achieved in the particularly stressed area of the pipe section against the special pressure loads after the closing device has been closed. The sleeve can be manufactured from plastic in a particularly inexpensive manner. An even higher strength at a lower price results if the sleeve is made of metal. A particularly long durability results if the sleeve is made of stainless steel. An aluminum sleeve has a particularly low weight and high strength. A particularly simple assembly of the hand-held spray gun according to the invention is obtained if projections for holding the pushed-on sleeve are provided on the feed area of the blank. A holder can be provided in a particularly simple manner if the outer diameter of the tubular feed region increases from the feed side, so that the sleeve can be pushed on and clamped in its end position. A simple pushing on during assembly results if longitudinal ribs projecting in sections on the circumference of the tubular feed area are provided, so that the pushed-on sleeve is held by clamping these ribs.
Eine optimale Haltbarkeit wird dadurch erreicht, dass die Hülse den Zufuhrbereich bis zur Höhe der Schließeinrichtung vollständig umfasst, so dass alle vom hohen Druck stromaufwärts der Schließeinrichtung erfassten Bereiche die gewünschte Verstärkung erfahren.Optimal durability is achieved in that the sleeve completely encloses the feed area up to the height of the closing device, so that all areas detected by the high pressure upstream of the closing device experience the desired reinforcement.
Ein zusätzlicher Vorteil der erfindungsgemäßen Handspritz- pistole besteht darin, dass auch in dem besonders beanspruchten Bereich stromaufwärts der Schließeinrichtung das Rohrstück im Zufuhrbereich dünnwandig und damit materialsparend ausgeführt werden kann.An additional advantage of the hand-held spray gun according to the invention is that, even in the particularly stressed area upstream of the closing device, the tube section in the feed area can be made thin-walled and thus saves material.
Besonders vorteilhaft ist es, wenn die Hülse eine zylindrische Innenkontur aufweist. In diesem Fall kann die Hülse aus einem einfachen Rohrabechnitt bestehen, zu dessen Herstellung ein handelsübliches Rohr mit passendem Innen-/ und Außendurchmesser durch einfaches Ablängen in die erforderlichen Abschnitte zerteilt wird. Auf diese Weise können die Hülsen besonders kostengünstig hergestellt werden. Wenn der Handbetätigungshebel in seinem Griffbereich einen U-förmigen Querschnitt aufweist, wobei die Schenkel des U einen größeren Abstand aufweisen, als der Durchmesser der Hülse, so kann bei gezogenem Handhebel der Handgriff so weit zurückgezogen werden, dass die beiden U-Schenkel des Handgriffs die Hülse umschließen. Dabei wird der Handgriff zusätzlich beim Anliegen der U-Schenkel an die Außenkontur der Hülse geführt. Dieses erhöht die Handhabungssicherheit der Handspritzpistole. Die nachfolgende Beschreibung dient der Erläuterung eines bevorzugten Ausführungsbeispieles der Erfindung, dabei zeigen: Figur 1: Einen Querschnitt durch eine erfindungsgemäße Handspritzpistole . Figur 2 : Die Seitenansicht eines erfindungsgernäßen Rohrstückes ohne aufgeschobene Hülse. Figur 3 : Ein Querschnitt durch ein erfindungsgemäßes Rohrstück mit Handgriff im geschlossenen Zustand.It when the sleeve has a cylindrical inner contour is particularly advantageous. In this case, the sleeve can consist of a simple tube processing, for the manufacture of which a commercially available tube with a suitable inside and outside diameter is divided into the required sections by simply cutting to length. In this way, the sleeves can be manufactured particularly inexpensively. If the manual operating lever has a U-shaped cross-section in its grip area, the legs of the U being at a greater distance than the diameter of the sleeve, the handle can be retracted so far when the manual lever is pulled that the two U-legs of the handle hold the Enclose sleeve. The handle is also guided when the U-leg touches the outer contour of the sleeve. This increases the handling safety of the hand spray gun. The following description serves to explain a preferred exemplary embodiment of the invention, in which: FIG. 1: A cross section through a hand spray gun according to the invention. Figure 2: The side view of a pipe piece according to the invention without a sleeve pushed on. Figure 3: A cross section through an inventive pipe piece with a handle in the closed state.
Figur 4 : Ein Querschnitt durch ein erfindungsgemäßes Rohrstück mit Handgriff im geöffneten Zustand bei gezogenem Betätigungshebel.Figure 4: A cross section through a pipe section according to the invention with a handle in the open state with the actuating lever pulled.
Wie aus Figur 1 ersichtlich besteht die Handspritzpiεtole aus einem Rohrstück (1) aus Kunststoff mit einem Flüssigkeitskanal (2) . Dem Flüssigkeitskanal (2) wird über einen Hochdruckschlauch (3) die Hochdruckflüssigkeit von der hier noch nicht dargestellten Hochdruckpumpe her zugeführt und über den Zufuhrbereich (4) bei geöffneter Schließeinrichtung (5) durch einen Bereich (6) stromabwärts der Schließ- einrichtung geleitet und durch ein an das Rohrstück (1) angeschlossene Rohr (7) zu einer weiteren Abgabeeinrichtung (hier nicht dargestellt), z.B. einer Hochdruckdüse für die Hochdruckflüssigkeit geführt.As can be seen from FIG. 1, the hand spray gun consists of a pipe section (1) made of plastic with a liquid channel (2). The high-pressure liquid is supplied to the liquid channel (2) via a high-pressure hose (3) from the high-pressure pump, which is not yet shown here, and is conducted via the supply area (4) with the closing device (5) open, through an area (6) downstream of the closing device and through a pipe (7) connected to the pipe section (1) to a further delivery device (not shown here), for example a high pressure nozzle for the high pressure liquid.
Der Hochdruckschlauch (3) weist an seinem Ende eine Hochdruckkupplung (8) auf, die mit einem Stecknippel (9) in den rohrformigen Zufuhrbereich (4) des Flüssigkeitkanals eingeschoben und mit einer U-förmigen Steckklammer (10) befestigt wird. Die Schließeinrichtung. (5) besteht aus einem Ventilkörper (11) mit einer Betätigungsstange (12), die aus dem Rohrstück (1) herausgeführt und durch den Handbetätigungshebel (13) verschoben wird. Der Ventilkörper (11) ist bei geschlossener Schließeinrichtung durch Federkraft gegen einen Ventilsitz gedrückt und verschließt damit den Flüssigkeitskanal. Zum Öffnen der Schließeinrichtung wird durch den Handbetätigungshebel (13) die Betätigungsstange verschoben und damit der Ventilkörper (11) von seinem Sitz abgehoben, so dass die Flüssigkeit zur Flüssigkeitsabgabeeinrichtung abfließen kann. Nach dem Loslassen des Handbetätigungshebels (15) wird der Ventilkörper durch Federkraft wieder gegen seinen Sitz gedrückt und verschließt den Durchgang durch die Flüssigkeit. Nach dem Ver- schluss der Schließeinrichtung (5) schaltet die Pumpe nicht unmittelbar ab, sondern es entsteht eine Druckerhöhung im Flüssigkeitskanal stromaufwärts der Schließeinrichtung (5) . Die dabei entstehenden Kräfte belasten das Rohrstück (1), welches insgesamt aus Kunststoff hergestellt ist, sehr stark in seinem Bereich stromaufwärts der Schließeinrichtung (5) . Das Rohrstück ist in seinem Zufuhrbereich (4) rohrförmig ausgebildet und auf diesen rohrförmig ausgebildeten Zufuhrbereich (4) ist eine Hülse (14) aufgeschoben, welche aus Metall besteht. Diese Hülse nimmt die nach dem Verschlies- sen der Schließeinrichtung auftretenden hohen Druckkräfte auf und schützt somit das Rohrstück (1) vor Zerstörung.The high-pressure hose (3) has a high-pressure coupling (8) at its end, which is inserted with a plug nipple (9) into the tubular feed area (4) of the liquid channel and fastened with a U-shaped plug clamp (10). The locking device. (5) consists of a valve body (11) with an actuating rod (12) which is led out of the pipe section (1) and moved by the manual actuating lever (13). When the closing device is closed, the valve body (11) is pressed against a valve seat by spring force and thus closes the liquid channel. To open the closing device, the operating rod is moved by the manual operating lever (13) and the valve body (11) is thus lifted from its seat, so that the liquid can flow off to the liquid dispensing device. After releasing the manual control lever (15), the valve body is pressed against its seat by spring force and closes the passage through the liquid. After the closing device (5) has been closed, the pump does not switch off immediately, but there is an increase in pressure in the liquid channel upstream of the closing device (5). The resulting forces place a heavy load on the pipe section (1), which is made entirely of plastic, in its area upstream of the closing device (5). The tube section is tubular in its feed area (4) and a sleeve (14) made of metal is slid onto this tubular feed area (4). This sleeve absorbs the high pressure forces that occur after the closing device is closed and thus protects the pipe section (1) against destruction.
Auf das Rohrstück (1) sind in seinem Zufuhrbereich (4) stromaufwärts der Schließeinrichtung (5), etwa auf Höhe der Schließeinrichtung, vorstehende Längsrippen (15) angebracht, auf denen die aufgeschobene Hülse (14) durch Verklemmung gehalten wird. Das Material der Hülse (14) ist widerstands higer als das Kunststoffmaterial, aus dem das Rohrstück (1) gefertigt ist. Die aufgeschobene Hülse (14) besteht bei dem beschriebenen Ausführungsbeispiel aus rostfreiem Edelstahl. Das Gehäuse (16) der erfindungsgemäßen Handspritzpistole besteht aus zwei Halbschalen. Zur Montage wird in eine geöffnete Halbschale (17) zunächst der Handbetätigungshebel (13) eingelegt. Danach wird das Rohrstück (1), mit vormontierter vo Zufuhrbereich her eingeschobener Schlieeseinrichtung (5) und aufgeschobener Hülse (14) eingelegt. Danach können die Teile der Handspritzpistole durch Aufschrauben der zweiten Halbschale fixiert werden. Wie aus Figur 3 zu erkennen ist, weist der HandbetätigungB- hebel (13) einen ü-förmigen Querschnitt auf. Die Darstellung in Figur 3 zeigt die Stellung bei gelöstem Handgriff und geschlossener Schließeinrichtung. Wie aus Figur 4 zu ersehen ist, kann der Handgriff in gezogener Stellung so weit gezogen werden, dass die seitlichen Schenkel (18, 19) die Hülse (14) umgreifen bzw. von dieser Hülse (14) geführt werden. On the pipe section (1) in its feed area (4) upstream of the closing device (5), approximately at the level of the closing device, projecting longitudinal ribs (15) on which the pushed-on sleeve (14) is held by jamming. The material of the sleeve (14) is more resistant than the plastic material from which the pipe section (1) is made. The pushed-on sleeve (14) consists of stainless steel in the described embodiment. The housing (16) of the hand spray gun according to the invention consists of two half-shells. For assembly, the manual control lever (13) is first inserted into an open half-shell (17). Then the pipe section (1) is inserted, with the locking device (5) and the sleeve (14) pushed in from the feed area. The parts of the hand spray gun can then be fixed by screwing on the second half shell. As can be seen from FIG. 3, the manual actuation lever (13) has a U-shaped cross section. The illustration in FIG. 3 shows the position when the handle is released and the locking device is closed. As can be seen from FIG. 4, the handle can be pulled so far in the pulled position that the lateral legs (18, 19) grip around the sleeve (14) or are guided by this sleeve (14).
