Abstract
Description
Die Erfindung betrifft ein handbetätigtes Werkzeug mit einem gegenüber einem Gehäuse verschwenkbaren Handgriff, einer Triebstange, welche mittels einer durch den Handgriff betätigbaren Antriebsmechanik achsial verstellbar ist, einer ersten und einer zweiten Schubstange, an deren vorderen Enden erste und zweite Kolben befestigt sind, wobei die Triebstange und die Schubstangen in einer Ebene liegen und die Schubstangen mit der Triebstange im Bereich ihrer hinteren Enden über einen Verbindungsbalken verbunden sind.The invention relates to a hand-operated tool with one versus one Housing swiveling handle, a drive rod, which by means of a is axially adjustable by the handle actuated drive mechanism, one first and a second push rod, at the front ends of which are first and second Pistons are attached, the drive rod and the push rods in one plane lie and the push rods with the push rod in the area of their rear ends are connected via a connecting bar.
Ein derartiges Werkzeug ist z.B. aus der US.A. 5314092 bekannt.Such a tool is e.g. from the UNITED STATES. 5314092 known.
Handbetätigte Werkzeuge mit einem gegenüber einem pistolenartigen Gehäuse des Werkzeuges verschwenkbaren Handgriff, durch welchen eine im Gehäuse gelagerte Schubstange schrittweise und achsial verstellbar ist, 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, wobei der Boden der Kartusche verschoben wird und die in der Kartusche befindliche Masse ausgepreßt wird. Solche Werkzeuge werden beispielsweise in der Bauindustrie verwendet zur Verlegung von Dichtmassen, doch auch für andere Einsatzzwecke sind solche Werkzeuge mit diesem Aufbau bekannt. Solche handbetätigte Werkzeuge sind beispielsweise in den nachstehend angeführten Veröffentlichungen dargestellt und beschrieben: EP-OS 645 194; GB-PS 703 780; US-PS 4 135 644; US-PS 5 052 243; EP-OS 108 584; WO 89/01322.Hand-operated tools with a pistol-like housing of the tool pivotable handle, through which a stored in the housing Push rod is gradually and axially adjustable, usually serve with the push rod, which carries a piston at one end, one in to squeeze a cartridge located mass, the cartridge in or on Housing of the tool can be fixed. By operating the handle the push rod with its piston is gradually pushed into the cartridge, whereby the bottom of the cartridge is moved and that in the cartridge existing mass is squeezed. Such tools are used, for example, in used in the construction industry to lay sealants, but also for others Such tools with this structure are known for their intended use. Such hand-operated Tools are for example in the publications listed below shown and described: EP-OS 645 194; GB-PS 703 780; US-PS 4,135,644; U.S. Patent 5,052,243; EP-OS 108 584; WO 89/01322.
Neben Kartuschen mit einer einzelnen mit einer auspreßbaren Masse gefüllten Hohlkammer werden auch sogenannte Zwillingskartuschen im Handel angeboten, welche zwei Hohlkammern aufweisen, in denen sich zwei verschiedene Komponenten befinden, die gleichzeitig ausgepreßt und dabei vermischt werden können. Verschiedene Ausführungsformen von Werkzeugen, mit denen solche Zwillingskartuschen ausgepreßt werden können, sind bekannt.In addition to cartridges with a single one filled with a squeezable mass So-called twin cartridges are also commercially available, which have two hollow chambers in which there are two different components are that can be squeezed out and mixed at the same time. Different embodiments of tools with which such twin cartridges can be squeezed out are known.
Die US-PS 4 566 610 zeigt ein Werkzeug, bei dem die beiden Schubstangen für die beiden Kammern der Kartusche jeweils einen eigenen Antrieb aufweisen. Nachteilig sind dabei der große Platzbedarf für die beiden getrennten Antriebe und der erhöhte Aufwand bei der Fertigung. The US-PS 4 566 610 shows a tool in which the two push rods for the two chambers of the cartridge each have their own drive. Disadvantages are the large space requirement for the two separate drives and the increased effort in manufacturing.
Um diese Nachteile zu überwinden, werden bei einem anderen vorbekannten Werkzeug für Zwillingskartuschen nicht die Schubstangen direkt angetrieben, sondern eine separate Triebstange, welche mit den beiden Schubstangen an ihrem rückwärtigen Ende über einen Verbindungsbalken verbunden ist, wird achsial verstellt. Um den notwendigen Platz für die Kartusche zu erhalten, sind dabei die Triebstange und die beiden Schubstangen in der Form eines Dreiecks (achsial gesehen) angeordnet. Dies hat aber den schwerwiegenden Nachteil, daß bei der Ausübung eines Drucks auf die Triebstange, um den Widerstand zu überwinden, den die auszupressende Masse den Schubstangen entgegensetzt, es zu seitlichen Verbiegungen aufgrund der auftretenden Hebelkräfte kommt. Dies geht so weit, daß ab einem gewissen Grenzwert der aufgewandten Kraft (z.B. 1200 N) überhaupt keine Vorschubbewegung, sondern nur noch eine seitliche Ausweichbewegung erreicht wird.To overcome these drawbacks, others are known Tool for twin cartridges not directly driving the push rods, but a separate drive rod, which with the two push rods on your rear end is connected via a connecting beam, becomes axial adjusted. To get the necessary space for the cartridge, the are The drive rod and the two push rods in the shape of a triangle (axial seen) arranged. But this has the serious disadvantage that the Exerting pressure on the drive rod to overcome the resistance, which the mass to be pressed opposes the push rods, to the side Bends due to the leverage that occurs. This goes so far that from a certain limit of the applied force (e.g. 1200 N) at all no feed movement, but only a lateral evasive movement is achieved.
Ein Werkzeug der eingangs genannten Art, welches ebenfalls vorbekannt ist, überwindet diese Probleme, indem die beiden Schubstangen und die Triebstange in eine Ebene gelegt werden. Damit sich dabei aber die Kartusche und die Triebstange nicht im Weg sind, ist die Triebstange nicht in der Mitte zwischen den beiden Schubstangen angeordnet, sondern seitlich versetzt davon, und zwar innerhalb des Hüllkreises eines der Kolben (in achsialer Sicht). Beim Auspressen der Kartusche beim Verschieben ihres Bodens mittels des Kolbens kann das freie Ende der Triebstange in den nunmehr hohlen hinteren Bereich der Kartusche eintauchen. Diese Konstruktion ist allerdings aufgrund des Platzbedarfes für die Antriebsmechanik nur beschränkt einsetzbar. Für Kartuschen, deren Durchmesser kleiner ist als 40 mm, ist eine praktische Realisierung der Konstruktion nicht mehr möglich. Ein weiterer Nachteil besteht in der stark unsymmetrischen Belastung des Verbindungsbalkens.A tool of the type mentioned at the beginning, which is also previously known, overcomes these problems by using the two push rods and the push rod placed on one level. So that the cartridge and the drive rod are not in the way, the drive rod is not halfway between the two Push rods arranged, but laterally offset from it, and within of the envelope circle of one of the pistons (in axial view). When squeezing the cartridge when moving its bottom by means of the piston, the free end of the Immerse the drive rod in the now hollow rear area of the cartridge. However, this construction is due to the space required for the drive mechanism can only be used to a limited extent. For cartridges with a smaller diameter than 40 mm, a practical implementation of the construction is no longer possible. Another disadvantage is the highly asymmetrical load on the connecting bar.
Aufgabe der Erfindung ist es, ein verbessertes handbetätigtes Werkzeug der eingangs genannten Art bereitzustellen, welches die Nachteile der bekannten Konstruktionen überwindet.The object of the invention is to provide an improved hand-operated tool Provide mentioned type, which has the disadvantages of the known constructions overcomes.
Erfindungsgemäß gelingt dies bei einem handbetätigten Werkzeug der eingangs genannten Art dadurch, daß der zweite Kolben zusätzlich am vorderen Ende der Triebstange befestigt ist. According to the invention, this succeeds with a hand-operated tool at the beginning mentioned type in that the second piston additionally at the front end of the Drive rod is attached.
Durch die Erfindung wird erkannt, daß Platz für die Antriebsmechanik geschaffen werden kann, wenn die Triebstange ebenfalls mit dem einen Kolben verbunden wird, die somit quasi als "dritte Schubstange" wirkt. Darüberhinaus sind durch die erfindungsgemäße Konstruktion sehr hohe Kräfte aufbringbar, wobei nur geringfügige unsymmetrische Belastungen auftreten.The invention recognizes that space is created for the drive mechanism can be if the drive rod is also connected to the one piston which acts as a "third push rod". Furthermore, through the Construction according to the invention very high forces can be applied, only slight asymmetrical loads occur.
Weitere Vorteile und Einzelheiten der Erfindung werden im folgenden anhand der beiliegenden Zeichnung anhand zweier Ausführungsbeispiele näher erläutert, ohne dadurch die Erfindung auf diese beiden Ausführungsbeispiele einzuschränken. In dieser zeigt:Further advantages and details of the invention are described below with reference to the accompanying drawing explained in more detail using two exemplary embodiments, without thereby restricting the invention to these two exemplary embodiments. In this shows:
Fig. 1 eine schematische Draufsicht auf ein erstes Ausführungsbeispiel der Erfindung, Fig. 2 eine Seitenansicht dieses Ausführungsbeispiels und Fig. 3 eine schematische Darstellung eines zweiten Ausführungsbeispiels der Erfindung.1 is a schematic plan view of a first embodiment of the invention, Fig. 2 is a side view of this embodiment and Fig. 3 is a schematic Representation of a second embodiment of the invention.
Das in den Fig. 1 und 2 gezeigte handbetätigte Werkzeug weist einen gegenüber
einem Gehäuse 1 verschwenkbaren Handgriff 2 auf. Im Gehäuse 1 ist eine in den
Figuren nicht weiter dargestellte Antriebsmechanik vorgesehen, wie sie bei solchen
Werkzeugen verwendet wird und die durch den Handgriff 2 betätigbar ist
und über die eine Triebstange 4 schrittweise achsial verstellbar ist. Da die Antriebsmechanik
nicht Gegenstand dieser Erfindung ist und bereits verschiedene
Formen von hier einsetzbaren Antriebsmechaniken bekannt geworden sind, wird
die Antriebsmechanik an dieser Stelle nicht weiter beschrieben.The hand-operated tool shown in FIGS. 1 and 2 has one opposite
a
Das Werkzeug weist weiters eine erste und eine zweite Schubstange 5, 6 auf, an
deren vorderen Enden erste und zweite Kolben 7, 8 befestigt sind. Die erste
Schubstange 5 kann dabei mittig oder auch außermittig am ersten Kolben 7 angreifen,
wogegen die zweite Schubstange 6 außermittig am zweiten Kolben 8 befestigt
ist. Das vordere Ende der Triebstange 4 ist ebenfalls starr mit dem zweiten
Kolben 8 verbunden. Entsprechend dem Ausführungsbeispiel nach den Fig. 1 und
2 greift die Triebstange 4 außermittig am zweiten Kolben 8 an.The tool also has a first and a
Die Schubstangen 5, 6 und die Triebstange 4 sind parallel zueinander angeordnet
und liegen in einer gemeinsamen Ebene. Im Bereich ihrer hinteren Enden sind die
Schubstangen 5, 6 und die Triebstange 4 über einen Verbindungsbalken 10 miteinander
verbunden. The
Das Werkzeug wird mit einer herkömmlichen Zwillingskartusche verwendet, die
bei zurückgefahrenen Kolben 7, 8 in den Trägerrahmen 9 eingelegt werden kann.
Am Trägerrahmen 9 sind dazu Halteelemente 15, 16 für die Kartusche vorgesehen.
Zum Auspressen der in den Hohlräumen der Kartusche enthaltenen Komponenten
werden die Schubstangen 5, 6 durch eine wiederholte Verschwenkung des
Handgriffs 2 nach vorne verschoben. Die dabei auftretenden Kräfte werden von
der erfindungsgemäßen Konstruktion bei nur geringfügigen unsymmetrischen
Belastungen nahezu verwindungsfrei aufgenommen. Ein erfindungsgemäßes
Werkzeug kann darüberhinaus auch für relativ kleine Kartuschen ausgelegt werden,
wobei die Antriebsmechanik aufgrund der optimalen Platzausnutzung dennoch
zwischen den Schubstangen 5, 6 Platz findet.The tool is used with a conventional twin cartridge that
can be inserted into the
Im Ausführungsbeispiel nach den Fig. 1 und 2 weisen die beiden Kolben 7, 8 die
gleichen Durchmesser bzw. Flächen auf. In Fig. 3 ist nun ein Ausführungsbeispiel
der Erfindung schematisch dargestellt, das für Zwillingskartuschen mit Kammern,
die unterschiedliche Größen besitzen, geeignet ist. Dazu weisen die Kolben 7, 8
unterschiedliche Durchmesser bzw. Flächen F1, F2 auf. Um beim Auspressen eine
günstige Beanspruchung der Konstruktion zu erreichen, kann in diesem Fall die
Anordnung der Triebstange 4 am Verbindungsbalken 10 außermittig sein. Das dabei
heranzuziehende Kriterium ist, daß das Verhältnis zwischen dem Abstand 12
zwischen der ersten Schubstange 5 und der Triebstange 4 und dem Abstand 13
zwischen der Triebstange 4 und der Mittellinie 14 durch den zweiten Kolben 8
möglichst dem Verhältnis zwischen der Fläche F2 des zweiten Kolbens 8 und der
Fläche F1 des ersten Kolbens 7 entsprechen soll. Dadurch werden die geringsten
unsymmetrischen Kräfte auf den Verbindungsbalken 10 ausgeübt. Die Mittellinie
14 durch den zweiten Kolben 8 ist durch die Oberflächennormale auf den zweiten
Kolben 8 definiert, welche durch den Mittelpunkt des zweiten Kolbens 8 führt. Da
die Flächen F1, F2 und der Abstand zwischen dem ersten und dem zweiten Kolben
7, 8 durch das Format der verwendeten Kartusche vorgegeben sind, bleibt als
freier Parameter der Befestigungspunkt 11 der Triebstange 4 am Verbindungsbalken
10, der möglichst entsprechend dem angegebenen Verhältnis gewählt wird. Im
Falle von gleich großen ersten und zweiten Kolben 7, 8, wie im Ausführungsbeispiel
nach den Fig. 1 und 2, kann diese Forderung allerdings nicht exakt erfüllt
werden.In the exemplary embodiment according to FIGS. 1 and 2, the two
Aus ästhetischen Gründen ist es weiters wünschenswert, wenn der Abstand zwischen
der ersten Schubstange 5 und der Triebstange 4 und der Abstand zwischen
der zweiten Schubstange 6 und der Triebstange 4 möglichst gleich sind. Dieser
Wunsch ist allerdings aus Symmetriegründen nicht immer mit der zuvor genannten
Forderung exakt vereinbar. For aesthetic reasons, it is also desirable if the distance between
