Description
Die vorliegende Erfindung betriff eine Hochdruckspritzpistole gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a high pressure spray gun according to the preamble of claim 1.
Solche Hochdruckspritzpistolen dienen vorwiegend der Reinigung von Oberflächen mittels Druckwasser, wobei ihr Einsatz vorwiegend im gewerblichen Bereich erfolgt. Dabei sind vielfach größere Flächen zu reinigen, die eine entsprechend lange Betätigungsdauer der Hochdruckspritzpistole erfordern, in der der Griffhebel gegen den Druck einer Feder, mit der ein Ventil in Schließstellung gehalten wird, betätigt werden muss.Such High-pressure spray guns are mainly used to clean surfaces using pressurized water. their use is predominantly in the commercial sector. there are often larger areas too clean, the correspondingly long operation duration of the high-pressure spray gun require in which the handle lever against the pressure of a spring, with the one valve in the closed position is held pressed must become.
Die Schaltung des Ventils kann mechanisch oder elektrisch erfolgen, wobei bei einer mechanischen Schaltung eine stärkere Feder zum Einsatz kommt.The Switching of the valve can be done mechanically or electrically, wherein in a mechanical circuit, a stronger spring is used.
In jedem Fall muss, um das Ventil geöffnet zu halten, der Griffhebel dauerhaft betätigt, das heißt gezogen werden.In In any case, to keep the valve open, the handle lever must permanently activated, that is pulled become.
Hierbei kommt es durch den Gegendruck der Feder zu großen Fingerbelastungen, die zu gesundheitlichen Problemen führen können, insbesondere zu ausgeprägten Muskelschädigungen. Überdies besteht die Gefahr bei einem längeren Halten des Griffhebels, dass die Finger erlahmen und den Griffhebel unkontrolliert freigeben.in this connection it comes by the back pressure of the spring to large finger loads, the lead to health problems can, especially too pronounced Muscle damage. moreover there is a risk of a prolonged Hold the handle lever so that the fingers go off and the handle lever is uncontrolled release.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Hochdruckspritzpistole der gattungsgemäßen Art so weiter zu entwickeln, dass der Griffhebel mit geringem Kraftaufwand in einer Funktionsstellung gehalten werden kann.Of the The present invention is therefore based on the object, a high-pressure spray gun of the generic type to develop so that the handle lever with little effort can be kept in a functional position.
Diese Aufgabe wird durch eine Hochdruckspritzpistole mit den Merkmalen des Anspruchs 1 gelöst.These Task is by a high-pressure spray gun with the features of claim 1.
Durch den in gezogener Stellung des Griffhebels an dessen freien Ende anliegenden Druckhebel wird die auf den Griffhebel aufzubringende Kraft, die ja, wie erwähnt, abhängig ist von der zu überwindenden Kraft der Ventilfeder, minimiert.By in the pulled position of the handle lever at the free end adjacent pressure lever is applied to the handle lever Force, which, as mentioned, dependent is from the to be overcome Force of the valve spring, minimized.
Üblicherweise ist die Griffseite des Griffhebels konkav ausgebildet, so dass das untere Ende des Griffhebels am Druckhebel anliegt, dessen Länge die Kraft bestimmt, die zur leichten Betätigung des Griffhebels erforderlich ist.Usually the handle side of the handle lever is concave, so that the lower end of the handle lever rests on the pressure lever whose length the Force determined necessary for easy operation of the handle lever is.
Die Länge des Druckhebels ist abhängig von dem zur Verfügung stehenden Raum, innerhalb dessen der Druckhebel verschwenkt werden kann.The Length of the Pressure lever is dependent from the available standing room within which the pressure lever are pivoted can.
Eine Minimierung der aufzubringenden Druckkraft ergibt sich durch die Ausnutzung der Gesamtlänge des Griffhebels als Hebelarm in Verbindung mit der Hebelwirkung des Druckhebels am Angriffspunkt des Griffhebels.A Minimization of applied pressure force results from the Utilization of the total length the handle lever as a lever arm in conjunction with the leverage of the pressure lever at the point of application of the handle lever.
Dadurch ist naturgemäß die Bedienung der Hochdruckspritzpistole vereinfacht bzw. merkbar erleichert, so dass auch längere Betätigungszeiten ermüdungsfrei für die Bedienungsperson möglich sind.Thereby is naturally the operation the high pressure spray gun simplified or noticeably easier, so that longer actuation times fatigue for the Operator possible are.
Diese verbesserte Handhabung führt letztendlich zu einer Minimierung der Kosten, da abzuspritzende Flächen aufgrund der geringeren Unterbrechungszeiten schneller bearbeitet werden können als dies bislang der Fall ist.These improved handling leads ultimately to a minimization of the costs, as to be sprayed surfaces processed faster due to the shorter interruption times can be as this is the case so far.
Daneben werden gesundheitliche Beeinträchtigungen, wie sie bisher zu beklagen waren, vermieden, so dass die Erfindung bezüglich der Handhabung der Hochdruckspritzpistole eine wesentliche Verbesserung gegenüber einer solchen nach dem Stand der Technik darstellt.Besides become health impairments, as they were so far to complain avoided, so that the invention in terms of the handling of the high pressure spray gun a significant improvement across from one of the prior art.
Hierzu trägt auch bei, dass, wie nach einem weiteren Gedanken der Erfindung vorgesehen, der Druckhebel als Verriegelungselement ausgebildet ist, mit dem der Griffhebel in einer Nichtfunktionsstellung gesichert gehalten wird.For this also carries in that, as provided for according to a further aspect of the invention, the pressure lever is designed as a locking element, with the the handle lever held secured in a non-functional position becomes.
Dabei liegt der Griffhebel mit seinem freien Ende in einer Vertiefung des Druckhebels ein, die einen Anschlag für den Griffhebel in Öffnungsrichtung bildet. Erst durch Ausrücken des Druckhebels aus dieser Arretierposition kann der Griffhebel frei betätigt werden.there is the handle lever with its free end in a recess of the pressure lever, which forms a stop for the handle lever in the opening direction. Only by disengagement the pressure lever from this locking position, the handle lever freely operated become.
Sowohl, um den Druckhebel in Verriegelungsstellung zu halten, wie auch, um ihn bei gezogenem Griffhebel in eine Druckstellung zu bringen, ist der Druckhebel federbelastet, vorzugsweise mittels einer Schenkelfeder, die sich einerseits am Griffteil und andererseits am Druckhebel selbst abstützt.Either, to hold the pressure lever in the locked position, as well, to bring him to a pressure position with the handle lever pulled the pressure lever is spring-loaded, preferably by means of a leg spring, on the one hand on the handle part and on the other hand on the pressure lever supports itself.
Nach einem weiteren Gedanken der Erfindung ist vorgesehen, dass an das Griffteil ein Stützbügel angeschlossen ist, der am Körper der Bedienungsperson anlegbar ist und durch den insbesondere Rückstoßkräfte, wie sie beim Einschalten der Hochdruckspritzpistole auftreten, aufgefangen werden. Dabei kann der Stützbügel im Bereich seiner Körperanlage konkav oder konvex ausgebildet sein, je nach Erfordernis.To Another idea of the invention is that to the Handle part connected to a support bracket is that on the body the operator can be applied and by the particular recoil forces, such as they occur when switching on the high-pressure spray gun, collected become. Here, the support bracket in the area his body be concave or convex, as required.
Auch diese Ausführungsvariante trägt zu einer Arbeitserleichterung der Hochdruckspritzpistole bei, wobei der Stützbügel vorzugsweise mit dem Griffteil verschraubt ist.Also this embodiment contributes a labor relief of the high-pressure spray gun, wherein the support bracket preferably is bolted to the handle.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.
