Description

Die Erfindung bezieht sich auf ein handbetätigtes Werkzeug mit einem gegenüber einem Gehäuse verschwenkbaren Handgriff mit den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a hand-operated tool with a pivotable handle relative to a housing with the features of the preamble of patent claim 1.

Handbetätigte Werkzeuge mit einem gegenüber einem pistolenartigen Gehäuse des Werkzeuges verschwenkbaren Handgriff, durch welchen eine im Gehäuse gelagerte Schubstange schrittweise und axial verstellbar sind, sind in verschiedenen Ausführungsformen bekannt geworden. Solche handbetätigte Werkzeuge sind beispielsweise in den nachstehend angeführten Veröffentlichungen dargestellt und beschrieben: GB-PS 703 780; US-PS 4 135 644; US-PS 5 052 243; EU-OS 108 584; WO 89/01322.Hand-operated tools with a pivotable handle relative to a pistol-like housing of the tool, by means of which a push rod mounted in the housing can be gradually and axially adjusted, have become known in various embodiments. Such hand-operated tools are shown and described, for example, in the publications listed below: GB-PS 703 780; U.S. Patent 4,135,644; U.S. Patent 5,052,243; EU-OS 108 584; WO 89/01322.

Handbetätigte Werkzeuge dieser Art dienen in der Regel dazu mit der Schubstange, die an ihrem einen Ende einen Kolben trägt eine in einer Kartusche befindliche Masse auszupressen, wobei die Kartusche im bzw. am Gehäuse des Werkzeuges festlegbar ist. Durch die Betätigung des Handgriffes wird die Schubstange mit ihrem Kolben schrittweise in die Kartusche hineingedrückt und dabei die in ihr befindliche Masse ausgepreßt. Solche Werkzeuge werden beispielsweise in der Bauindustrie verwendet zur Verlegung von Dichtmassen, doch auch für andere Einsatzzwecke sind solche Werkzeuge mit diesem Aufbau bekannt.Hand-operated tools of this type are usually used with the push rod, which carries a piston at one end, to press out a mass located in a cartridge, the cartridge being fixable in or on the housing of the tool. By actuating the handle, the push rod with its piston is gradually pushed into the cartridge and the mass in it is squeezed out. Such tools are used, for example, in the construction industry for laying sealing compounds, but such tools with this structure are also known for other purposes.

Um die Schubstange durch die periodische Bewegung des verschwenkbaren Handgriffes axial zu verschieben, ist an der Schubstange eine Zahnung vorgesehen (EU-OS 108 584; US-PS 4 135 644), in welche eine mit dem Handgriff verbundene Klinke eingreift. Da an dieser Eingreifstelle doch erhebliche Kräfte wirksam sind, verschleißen die miteinander kämmenden Teile sehr rasch, so daß dann das Werkzeug unbrauchbar wird. In der Weiterentwicklung solcher Werkzeuge wurde dazu übergegangen die Schubstange glatt auszubilden und an ihr einen Kantkloben anzusetzen (GB-PS 703 780; US-PS 5 052 243; WO 89/01322), der vom Handgriff direkt oder über eine Übersetzung betätigbar ist. Dieser Kantkloben wird dabei von einer von der Schubstange durchsetzten Schraubenfeder gegen einen Anschlag gedrückt, beispielsweise an den in seiner Ruhestellung befindlichen Handgriff. Wird nun der Handgriff verschwenkt, so wird der Kantkloben gegenüber der Achse der Schubstange schräggestellt, er verklemmt sich an der Schubstange und zieht diese in der Folge mit. Diese Mechanik ist zwischen zwei die Schubstange tragenden Lagern vorgesehen. Im Grunde hat sich diese Verstellmöglichkeit für die Schubstange durchaus bewährt, doch ist hier zu beachten, daß bei der Betätigung des Handgriffes und die dadurch bedingte Beanspruchung der miteinander in Wirkverbindung stehenden Bauteile eine erhebliche Biegebeanspruchung auf den zwischen den beiden Lagern befindlichen Teil der Schubstange ausgeübt wird und die dadurch hervorgerufenen Reaktionskräfte in den Lagern müssen manuell überwunden werden, so daß ein beächtlicher Teil der manuell aufgebrachten Kraft zur Überwindung von Reibungskräften und Verformungskräften aufgezehrt wird was ohne Zweifel nachteilig ist und die Effizienz des Werkzeuges beeinträchtigt.In order to axially move the push rod by the periodic movement of the pivotable handle, a toothing is provided on the push rod (EU-OS 108 584; US Pat. No. 4,135,644) into which a pawl connected to the handle engages. Since considerable forces are effective at this point of engagement, the intermeshing parts wear out very quickly, so that the tool is then unusable. In the further development of such tools, the push rod has been smoothly designed and a square block has to be attached to it (GB-PS 703 780; US-PS 5 052 243; WO 89/01322), which can be actuated by the handle directly or via a translation. This square block is pressed against a stop by a helical spring penetrated by the push rod, for example against the handle in its rest position. If the handle is now pivoted, the square block is opposite the axis of the Push rod tilted, it jams on the push rod and pulls it with it as a result. This mechanism is provided between two bearings that support the push rod. Basically, this adjustment option for the push rod has proven itself, but it should be noted here that when the handle is actuated and the resulting stress on the components in operative connection, a considerable bending stress is exerted on the part of the push rod located between the two bearings and the resulting reaction forces in the bearings must be overcome manually, so that a considerable part of the manually applied force is overcome to overcome frictional and deforming forces, which is undoubtedly disadvantageous and affects the efficiency of the tool.

Ziel und Aufgabe der Erfindung ist daher, diese vorbekannte Konstruktion dahingehend zu verbessern, daß die manuell aufgebrachten Kräfte möglichst effizient, also vollständig als Vorschubkraft für die Schubstange wirksam wird, was erfindungsgemäß durch jene Maßnahmen gelingt die Inhalt und Gegenstand des kennzeichnenden Teiles des Patentanspruches 1 sind.The aim and object of the invention is therefore to improve this known construction in such a way that the manually applied forces are as efficient as possible, that is to say fully effective as a feed force for the push rod, which, according to the invention, is achieved through those measures, the content and subject of the characterizing part of claim 1 .

Um die Erfindung zu veranschaulichen, wird sie anhand eines schematisch dargestellten Ausführungsbeispieles näher erläutert, ohne sie dadurch auf das gezeigte Anwendungsbeispiel einzuschränken. Es zeigen:
Fig. 1 die für den Antrieb der Schubstange wesentlichen Bauelemente in Draufsicht und Fig. 2 in Seitensicht.In order to illustrate the invention, it is explained in more detail with the aid of a schematically illustrated exemplary embodiment, without thereby restricting it to the application example shown. Show it:
Fig. 1 shows the essential components for driving the push rod in plan view and Fig. 2 in side view.

Das Werkzeug, mit dem beispielsweise aus Kartuschen Dichtmassen auspreßbar sind, besitzt ein pistolenartiges Gehäuse 1, in welchem eine Schubstange 2 mit einem Kolben 3 axial verschiebbar gelagert ist. Diese Schubstange 2 ist von drei gehäuseseitigen Lagern 4, 5 und 6 getragen. Zur Aufnahme und Festlegung der die auszupressende Dichtmasse beinhaltenden, hier nicht dargestellten Kartusche dient ein gehäuseseitiger Rahmen 7.The tool, with which sealing compounds can be pressed out of cartridges, for example, has a pistol-like housing 1 in which a push rod 2 with a piston 3 is axially displaceably mounted. This push rod 2 is supported by three bearings 4, 5 and 6 on the housing side. A frame 7 on the housing side serves to receive and fix the cartridge, which is not shown here, which contains the sealing compound to be pressed out.

Innerhalb des Gehäuses 1 durchsetzt die Schubstange 2 zwei - bezüglich ihrer Achse - symmetrisch zueinander angeordnete Kantkloben 8. Jeder Kantkloben 8 ist im wesentlichen als quaderförmiges Plättchen ausgebildet, welches in seinem einen Abschnitt eine Öffnung oder Bohrung 9 besitzt, deren Durchmesser um ein geringes Maß größer ist als der Durchmesser der Schubstange 2. In jenem Abschnitt dieser Kantkloben 8, in dem die Bohrung 9 für den Durchtritt der Schubstange 2 vorgesehen ist und mit welchem sie sich gegenseitig überlappen, sind diese quaderförmigen Plättchen stufenförmig abgesetzt und besitzen hier eine geringere Stärke als in jenem Abschnitt, der der Schubstange 2 abgewandt ist. Eine im Gehäuse 1 abgestützte Schraubenfeder 10, die von der Schubstange 2 durchsetzt liegt mit ihrem anderen Ende am einen Kantkloben 8 an. Auf der dieser Feder 10 abgewandten Seite, und zwar an den äußeren Abschnitten dieser beiden Kantkloben 8 liegen die Gabelarme 11 des um die Achse 13 schwenkbaren Handgriffes 12 an. Eine gedachte Verbindungslinie der beiden Anlagepunkte liegt im wesentlichen parallel zur Schwenkachse 13 des Handgriffes 12.Within the housing 1, the push rod 2 passes through two square blocks 8 which are arranged symmetrically with respect to one another with respect to their axis. Each square block 8 is essentially designed as a cuboid plate which has an opening or bore 9 in its one section, the diameter of which is slightly larger is than the diameter of the push rod 2. In that section of this square block 8 in which the bore 9 is provided for the passage of the push rod 2 and with which they overlap one another, these are cuboid The platelets are stepped and have a lower thickness here than in the section facing away from the push rod 2. A helical spring 10 which is supported in the housing 1 and which is penetrated by the push rod 2 rests with its other end on an edge block 8. On the side facing away from this spring 10, specifically on the outer sections of these two square blocks 8, the fork arms 11 of the handle 12 pivotable about the axis 13 rest. An imaginary connecting line between the two contact points lies essentially parallel to the pivot axis 13 of the handle 12.

Um die Schubstange 2 in ihrer jeweiligen, vorgeschobenen Lage gegen die auf sie einwirkende axiale Reaktionskraft zu halten, sind noch Bremskloben 14, ebenfalls in paarweiser - bezogen auf die Achse der Schubstange 2 - symmetrischer Anordnung vorgesehen, die in ihrer Ruhelage durch eine Schraubenfeder 15 gehalten sind, die sich einerseits an einem der Bremskloben 14 und andererseits an einem Teil des Gehäuses 1 abstützt. Diese Bremskloben 14 sind identisch geformt wie die Kantkloben 8. Mit ihren äußeren Abschnitten liegen sie an gehäuseseitigen Lagern an. Parallel zur Schubstange 2 ist ein Schaltstift 16 gegen die Kraft einer Feder 17 verschiebbar gelagert, der mit seinem inneren Ende am einen der paarweise vorgesehenen Bremskloben 14 anliegt.In order to hold the push rod 2 in its respective advanced position against the axial reaction force acting on it, brake blocks 14 are also provided, also in pairs - with respect to the axis of the push rod 2 - in a symmetrical arrangement, which are held in their rest position by a coil spring 15 are supported on the one hand on one of the brake blocks 14 and on the other hand on a part of the housing 1. These brake blocks 14 are shaped identically to the square blocks 8. With their outer sections, they rest on bearings on the housing side. Parallel to the push rod 2, a switching pin 16 is displaceably mounted against the force of a spring 17, the inner end of which rests on one of the brake blocks 14 provided in pairs.

Wenn im gezeigten Ausführungsbeispiel die Gabelarme 11 des Handgriffes 12 direkt auf die Kantkloben 8 einwirkt und an diesen angreift, so liegt es im Rahmen der Erfindung, zwischen Handgriff 12 und Kantkloben 8 ein Übertragungsmechanismus vorzusehen, eventuell mit einer geeigneten Übersetzung.If, in the exemplary embodiment shown, the fork arms 11 of the handle 12 act directly on the square block 8 and act on it, it is within the scope of the invention to provide a transmission mechanism between the handle 12 and the square block 8, possibly with a suitable translation.

In der Ausgangslage befindet sich der Kolben 3 bzw. die Schubstange 2 - bezogen auf die Fig. 1 und 2 - links. Wird der Handgriff 12 des pistolenartigen Gehäuses 1 verschwenkt (Pfeil 18) gegen die Kraft der Feder 20, so werden über die Gabelarme 11 die Kantkloben 8 gegen die Kraft der Feder 10 verkantet, sie legen sich reibungsschlüssig an der Schubstange 2 fest und die Schubstange 2 wird nun um ein Maß nach rechts geschoben, das der Sehnenlänge des Schwenkbogens der Gabelarme 11 entspricht. Die nur durch die Feder 15 belasteten Bremskloben 14 behindern diese Bewegung nicht. Wird der Handgriff 12 losgelassen, der aufgrund der auf ihn einwirkenden Kraft der Feder 20 in seine Ausgangslage zurückkehrt, so werden die Kantkloben 8 durch die vorgespannte Feder 10 in ihre aus Fig. 1 ersichtliche Lage zurückgedrückt. Die auf den Kolben 3 einwirkende Reaktionskraft (Pfeil 19) der in der nicht dargestellten Kartusche befindlichen Masse, versucht die Schubstange 2 zurück, nach links zu schieben. Diese Bewegung wird aber durch die unter der Wirkung der Kraft der Feder 15 stehenden Bremskloben nun blockiert, die ja durch die Kraft dieser Feder gegenüber der Schubstange 2 verkantet sind und diese reibungsschlüssig festhalten. Durch periodische Bewegungen des Handgriffes 12 wird die Schubstange 2 bzw. der Kolben 3 schrittweise nach rechts bewegt. Soll der schlußendlich in der rechten Endlage befindliche Kolben wieder in seine Ausgangslage zurückgebracht werden, so werden durch Drücken des Schaltstiftes 16 die Bremskloben 14 gegen die Kraft der Feder 15 etwas verschwenkt, so daß der Reibungsschluß zwischen den Bremskloben 14 und der Schubstange 2 aufgehoben ist und dadurch die Schubstange 2 manuell zurückgezogen werden kann.In the starting position, the piston 3 or the push rod 2 - based on FIGS. 1 and 2 - is on the left. If the handle 12 of the pistol-like housing 1 is pivoted (arrow 18) against the force of the spring 20, the claw clamps 8 are tilted against the force of the spring 10 via the fork arms 11, they fix frictionally on the push rod 2 and the push rod 2 is now pushed to the right by an amount that corresponds to the chord length of the swivel bow of the fork arms 11. The brake block 14 loaded only by the spring 15 does not hinder this movement. If the handle 12 is released, which returns to its starting position due to the force of the spring 20 acting on it, the claw clamps 8 are pushed back into their position shown in FIG. 1 by the prestressed spring 10. The reaction force acting on the piston 3 (arrow 19) of the mass in the cartridge (not shown) tries to push the push rod 2 back to the left. But this movement is caused by the under the action of the force of the spring 15 standing brake block now blocked, which are tilted by the force of this spring relative to the push rod 2 and hold it frictionally. Periodic movements of the handle 12 gradually move the push rod 2 or the piston 3 to the right. If the piston, which is finally in the right end position, is to be returned to its starting position, the brake block 14 is pivoted somewhat against the force of the spring 15 by pressing the switching pin 16, so that the frictional engagement between the brake block 14 and the push rod 2 is canceled and thereby the push rod 2 can be withdrawn manually.

Durch die symmetrische Anordnung der Kantkloben 8 und der Bremskloben 14 wirken auf die Schubstange 2 praktisch nur achsparallele Kräfte ein, wodurch nicht nur die Verformung der Schubstange, sondern auch die ungleichmäßige Belastung der Lager verhindert wird und so die manuell über den Handgriff 12 aufgebrachten Kräfte effizient zum Verschub der Schubstange 2 einsetzbar sind.Due to the symmetrical arrangement of the square block 8 and the brake block 14, practically only axially parallel forces act on the push rod 2, which not only prevents the deformation of the push rod, but also the uneven loading of the bearings and thus the forces applied manually via the handle 12 efficiently can be used to move the push rod 2.

Die Längsachsen der beiden Kantkloben 8, das sind die in Fig. 1 zur Zeichenebene parallel liegenden Achsen derselben, schließen beim gezeigten Ausführungsbeispiel miteinander einen gestreckten Winkel von 180° ein. Es liegt im Rahmen der Erfindung, diese paarweise vorgesehenen Kantkloben 8 so zueinander anzuordnen, daß ihre Achsen einen stumpfen oder gar spitzen Winkel miteinander einschließen. Der durch die Erfindung angestrebte Zweck, die Schubstange 2 von Biegekräften so weit wie möglich freizuhalten, wird in diesem Falle allerdings nur in beschränktem Umfang erreicht.The longitudinal axes of the two cantilever blocks 8, that is, the axes thereof lying parallel to the plane of the drawing in FIG. 1, enclose an extended angle of 180 ° with one another in the exemplary embodiment shown. It is within the scope of the invention to arrange these claw clamps 8, which are provided in pairs, so that their axes enclose an obtuse or even acute angle with one another. The aim of the invention to keep the push rod 2 free of bending forces as far as possible is achieved in this case only to a limited extent.
