Abstract
Description
Die Erfindung bezeichnet ein Rührwerkzeug bspw. zum Verrühren von Farben oder Estrich im Baugewerbe, das über ein Einsteckende mit einer zumindest teilweise drehenden Handwerkzeugmaschine, insbesondere einem Bohrhammer, verbindbar ist.The invention refers to a stirring tool, for example, for mixing paints or screed in the construction industry, which can be connected via an insertion end to an at least partially rotating hand tool machine, in particular a hammer drill.
Üblicherweise weisen derartige Rührwerkzeuge einen steifen länglichen Schaft auf, an dessen einem Ende ein radial auskragendes Rührmittel (Rührbleche, Rührlamellen, Rührschlingen etc.) ausgebildet ist und an dessen anderen Ende ein zur drehmoment übertragenden Verbindung mit der Werkzeugaufnahme einer drehenden Handwerkzeugmaschine ausgebildetes Einsteckende vorhanden ist. Dazu reicht schon ein zylinderförmiger Teil des Schafts, welcher in ein Dreibackenfutter gespannt werden kann.Usually, such stirring tools on a rigid elongate shaft, at one end of a radially projecting stirring means (stirrers, stirring blades, agitating loops, etc.) is formed and at the other end of a torque transmitting connection formed with the tool holder of a rotary power tool insertion end is present. This is enough already a cylindrical part of the shaft, which can be stretched in a three-jaw chuck.
Nach der
Nachteilig bei derartigen Rührwerkzeugen ist das Anhaften des zu mischenden zähflüssigen Materials am Rührwerk, insbesondere nach beendeter zweckentsprechender Verwendung, wenn das Rührwerkzeug gesäubert werden soll.A disadvantage of such stirring tools is the adhesion of the viscous material to be mixed to the agitator, in particular after completion of appropriate use when the stirring tool is to be cleaned.
Zudem sind bei Schlagbohrwerkzeugen auch Schlagwerkzeug-Einsteckenden vorbekannt, insbesondere die derzeit bei Bohrhammersystemen weltweit meistgenutzten, praktisch standardisierten Einsteckenden bei Schlagbohrern und zugeordneten Werkzeugaufnahmen nach der
Die Aufgabe der Erfindung besteht in der Realisierung eines Rührwerkzeugs, welches die Reinigung desselben nach zweckentsprechender Verwendung besser unterstützt.The object of the invention is the realization of a stirring tool which better supports the cleaning of the same after appropriate use.
Die Aufgabe wird im Wesentlichen durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The object is essentially achieved by the features of
So weist ein Rührwerkzeug einen steifen länglichen Schaft auf, an dessen einem Ende ein radial auskragendes Rührmittel ausgebildet ist und an dessen anderem Ende zur drehmomentübertragenden Verbindung mit einer Werkzeugaufnahme einer drehenden Handwerkzeugmaschine geeignetes Einsteckende ausgebildet ist, wobei dieses zumindest eine axial beidseitig geschlossene Verriegelungsnut aufweist.Thus, a stirring tool on a rigid elongated shaft, at one end of a radially projecting stirring means is formed and at its other end for torque-transmitting connection with a tool holder of a rotary power tool suitable insertion end is formed, which has at least one axially closed on both sides locking groove.
In die axial beidseitig geschlossene Verriegelungsnut kann ein Verriegelungskörper einer passend zugeordneten Schlagwerkzeugaufnahme eingreifen. Das somit als begrenzt axial bewegliches Schlagwerkzeug-Einsteckende ausgebildete Einsteckende eignet sich ebenso gut wie die vorbekannten Einsteckenden zur zweckentsprechenden Verwendung bei der Mischung von zähflüssigen Materialien. Der Schlagantrieb eines antreibenden Bohrhammers sollte dann deaktiviert sein. Zur Säuberung des Rührwerkzeugs, bspw. in klarem Wasser, sollte der Schlagantrieb aktiviert werden, wobei insbesondere bei axialer Bewegung des Rührwerkzeugs (im Wasser) und dadurch bedingter Versetzung des Einsteckendes innerhalb der Schlagwerkzeugaufnahme eine Schlagübertragung auf das Rührwerkzeug stattfindet, wodurch sich das anhaftende zähflüssige Material wesentlich besser ablöst als bei reiner Drehung im Wasser. Ohne axiale Bewegung (im Wasser) hingegen wird auch bei aktiviertem Schlagantrieb praktisch kein Schlag auf das Rührwerkzeug übertragen, wodurch es dann weniger spritzt. Somit ist der Säuberungsprozess manuell intuitiv kontrollierbar.In the axially closed on both sides locking groove can engage a locking body of a suitably associated impact tool holder. The thus formed as a limited axially movable impact tool-Einsteckende trained insertion is as well as the previously known Einsteckenden for appropriate use in the mixture of viscous materials. The impact drive of a driving hammer drill should then be deactivated. To clean the stirrer, eg. In clear water, the percussion drive should be activated, in particular during axial movement of the stirring tool (in the water) and consequent displacement of the insertion inside the impact tool receiving a shock transfer to the stirring takes place, resulting in the adhesive viscous material much better peel off than pure rotation in the water. Without axial movement (in the water), however, practically no impact is transmitted to the stirring tool even when the impact drive is activated, whereby it then injects less. Thus, the cleaning process is manually controlled intuitively.
Vorteilhaft ist das Einsteckende entsprechend handelsüblicher Schlagwerkzeug-Einsteckenden ausgebildet, insbesondere entsprechend des SDS-Plus-Einsteckendes mit 10mm Führungsdurchmesser und je zwei umlaufend gegenüberliegenden, stirnseitig offenen trapezförmigen Drehmitnahmenuten und beidseitig geschlossenen Verriegelungsnuten, oder des SDS-max-Einsteckendes mit 18mm Führungsdurchmesser und mit zwei umlaufend gegenüberliegenden beidseitig geschlossenen Verriegelungsnuten und drei stirnseitig offenen trapezförmigen Drehmitnahmenuten, wodurch das Rührwerkzeug in verbreitete Schlagwerkzeugaufnahmen einsetzbar ist. Zudem ist ein derartiges Einsetzen in eine moderne Schlagwerkzeugaufnahme wesentlich komfortabler und schneller, als jenes in eine reine übliche Drehwerkzeugaufnahme, insbesondere eines Dreibackenfutters.Advantageously, the insertion is designed according to commercial impact tool insertion ends, in particular according to the SDS-Plus-Einsteckendes with 10mm guide diameter and two circumferentially opposite, frontally open trapezoidal rotary drive grooves and locking grooves closed on both sides, or the SDS-max-Einsteckendes with 18mm guide diameter and two circumferentially opposite on both sides closed locking grooves and three frontally open trapezoidal rotary driving grooves, whereby the stirring tool is used in common impact tool receptacles. Moreover, such an insertion into a modern striking tool recording much more comfortable and faster than that in a pure conventional rotary tool holder, in particular a three-jaw chuck.
