Description

Horizontale Verlängerung für Betätigungswerkzeuge mit Mehrkantan¬ triebHorizontal extension for actuating tools with polygon drive
Die vorliegende Erfindung bezieht sich auf Verlängerungen für Betätigungs¬ werkzeuge mit Mehrkantantrieb insbesondere mit Sechs- oder Vierkantantrieb nach Maßgabe des Oberbegriffes des Patentanspruches 1.The present invention relates to extensions for actuating tools with a polygonal drive, in particular with a hexagonal or square drive, in accordance with the preamble of claim 1.
Ein bekanntes Problem bei der Verwendung von Betätigungswerkzeugen mit Vierkantantrieb, insbesondere Ratschen oder Knarren, ist das Anziehen oder Lösen von Schrauben, die an derartig ungünstigen Positionen angeordnet sind, daß sie durch das eigentliche Grundwerkzeug nicht zugänglich sind. Dement¬ sprechend sind axiale Verlängerungen zwischen dem Antriebskopf eines derarti¬ gen Betätigungswerkzeuges und dem Steckschlüssel in verschiedenen Längen und Ausführungen entwickelt worden. Sogar für Schrauben, die abweichend von der Werkzeugachse positioniert sind, existieren derartige axiale Verlängerungen, wobei hier Kardangelenke zum Einsatz kommen. Die Verwendung dieser Ver¬ längerungen mit Kardangelenken für Schrauben, die abweichend von der Werk- zeugachse positioniert sind, setzt aber einen ausreichenden vertikalen Spielraum zum Werkzeugeinsatz voraus. Dieser Spielraum entspricht dabei etwa der Ent¬ fernung zwischen Werkzeugachse und Schraube zuzüglich der Gelenkverlänge¬ rung. Steht dieser vertikale Spielraum nicht zur Verfügung, ist der Einsatz der Verlängerungen nicht möglich.A known problem when using actuating tools with a square drive, in particular ratchets or creaking, is the tightening or loosening of screws which are arranged in such unfavorable positions that they are not accessible by the actual basic tool. Accordingly, axial extensions between the drive head of such an actuating tool and the socket wrench have been developed in various lengths and designs. Even for screws that are positioned differently from the tool axis, there are such axial extensions, whereby universal joints are used here. The use of these extensions with universal joints for screws that differ from the factory tool axis are positioned, but requires sufficient vertical scope for tool use. This margin corresponds approximately to the distance between the tool axis and the screw plus the joint extension. If this vertical scope is not available, the extensions cannot be used.
Die Aufgabe der vorliegenden Erfindung ist es, eine Verlängerung für Betäti¬ gungswerkzeuge mit Mehrkantantrieb vorzusehen, die eine Bewegung von Schrauben zuläßt, die abweichend von der Werkzeugachse positioniert sind und bei denen kein ausreichender vertikaler Spielraum für den Einsatz von mit Kar¬ dangelenken versehenen axialen Verlängerungen vorhanden ist.The object of the present invention is to provide an extension for actuating tools with a polygonal drive, which permits the movement of screws which are positioned differently from the tool axis and in which there is insufficient vertical clearance for the use of axial extensions provided with cardan joints is available.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Schutzanspruches 1 gelöst, wobei zweckmäßige Ausführungsformen durch die Unteransprüche ge¬ kennzeichnet sind.This object is achieved by the characterizing features of the protection claim 1, expedient embodiments being characterized by the subclaims.
Erfindungsgemäß ist eine rechtwinklig zur Betätigungsachse eines Werkzeuges mit Mehrkantantrieb aufsteckbare horizontale Verlängerung vorgesehen. Diese besteht aus einem vorzugsweise aus zwei Schalen aufgebauten Schaft mit daran angeordneten Antriebsköpfen, in denen jeweils ein Antriebsrad, vorzugsweise ein Zahnrad angeordnet ist, die über eine Kette, einen Zahnriemen, Schubglieder oder etwas ähnliches verbunden sind. Bevorzugterweise ist eines der Antriebsrä¬ der mit einer Mehrkantöffnung ausgestattet, die das Einstecken des Betäti¬ gungswerkzeuges erlaubt, während das zweite Antriebsrad mit einem Mehr¬ kantzapfen ausgerüstet ist, der der Aufnahme des Steckschlüssels dient. Ebenso ist es auch denkbar, beide Antriebsräder mit einer Mehrkantöffnung auszustat¬ ten, wobei die Steckschlüsselaufnahme in diesem Falle mittels handelsüblicher Mehrkantverbindungsstücke erfolgt. Je nach Einsatzbedingungen und Ausfüh¬ rungsform können die einzelnen Elemente der horizontalen Verlängerung aus Metall, Kunststoff oder jedem anderen geeignet erscheinenden Material herge¬ stellt sein. Mit der horizontalen Verlängerung ergibt sich auf überraschend einfache Weise die vorteilhafte Möglichkeit, Schraubarbeiten auch an schwer zugänglichen Stel¬ len, etwa bei Maschinen, Motorräumen sowie allgemeinen Montagearbeiten durchzuführen. Es werden dabei Schraubverbindungen an Stellen möglich, die der Verschraubung bisher nicht zugänglich waren oder erst durch eine geänderte Konstruktion verschraubbar gemacht werden konnten. Die erfindungsgemäße Verlängerung ist dabei mit allen üblichen Betätigungswerkzeugen und dem ent¬ sprechenden Zubehör kombinierbar.According to the invention, a horizontal extension that can be plugged on at right angles to the actuation axis of a tool with a polygonal drive is provided. This consists of a shaft, preferably constructed from two shells, with drive heads arranged thereon, in each of which a drive wheel, preferably a gearwheel, is arranged, which are connected via a chain, a toothed belt, thrust links or something similar. One of the drive wheels is preferably equipped with a polygonal opening which allows the actuating tool to be inserted, while the second drive wheel is equipped with a polygonal pin which serves to receive the socket wrench. It is also conceivable to equip both drive wheels with a polygonal opening, in which case the socket wrench receptacle takes place by means of commercially available polygonal connecting pieces. Depending on the conditions of use and the embodiment, the individual elements of the horizontal extension can be made of metal, plastic or any other suitable material. With the horizontal extension, there is a surprisingly simple way of carrying out screwing work even in hard-to-reach places, for example in machines, engine compartments and general assembly work. Screw connections are possible at locations that were previously not accessible to the screw connection or that could only be made screwable by a modified construction. The extension according to the invention can be combined with all the usual actuating tools and the corresponding accessories.

In der Fig. 1 ist eine horizontale Verlängerung mit zwei Schalen 1 und 2 darge¬ stellt, die zusammen die Antriebsköpfe 3 und 4 sowie den Schaft 5 zwischen den Köpfen 3 und 4 bilden. Die Schalen 1 und 2 sind im dargestellten Ausführungs¬ beispiel miteinander verschraubt, wobei aber auch jede andere mögliche Verbin¬ dungsweise denkbar ist. In den Antriebsköpfen ist jeweils ein Antriebsrad, hier ein Zahnrad angeordnet, wobei in dem Ausfuhrungsbeispiel nach Fig. 1 eines der Zahnräder mit einer Vierkantöffnung 6 ausgestattet ist, während das andere Zahnrad am gegenüberliegenden Antriebskopf mit einem Vierkantzapfen 7 ver¬ sehen ist, der zur Steckschlüsselaufnahme dient.1 shows a horizontal extension with two shells 1 and 2, which together form the drive heads 3 and 4 and the shaft 5 between the heads 3 and 4. The shells 1 and 2 are screwed together in the embodiment shown, but any other possible connection is also conceivable. A drive wheel, here a gearwheel, is arranged in the drive heads, one of the gearwheels in the exemplary embodiment according to FIG. 1 being equipped with a square opening 6, while the other gearwheel on the opposite drive head is provided with a square pin 7, which is used to hold the socket wrench serves.
Die Fig. 2 zeigt ein Zahnrad 8, das mit einer Vierkantöffnung 6 versehen ist und einen Zahnkranz 9 trägt. Das Zahnrad des gegenüberliegenden Kopfes der hori¬ zontalen Verlängerung ist vorzugsweise identisch ausgebildet, abgesehen davon, daß anstelle der Vierkantöffnung ein Vierkantzapfen 7 vorgesehen sein kann.Fig. 2 shows a gear 8, which is provided with a square opening 6 and carries a ring gear 9. The gear wheel of the opposite head of the horizontal extension is preferably of identical design, apart from the fact that a square pin 7 can be provided instead of the square opening.
Die Fig. 3 zeigt eine Draufsicht auf die horizontale Verlängerung nach Fig. 1 wo¬ bei über die bereits bekannten Merkmale hier insbesondere die Schrauben 10 zur Verbindung der die Verlängerung bildenden Schalen zu erkennen sind.FIG. 3 shows a top view of the horizontal extension according to FIG. 1, although the screws 10 for connecting the shells forming the extension can be seen here in particular via the features already known.
Die Fig. 4 zeigt die Draufsicht auf ein Zahnrad wie in Fig. 2 dargestellt.FIG. 4 shows the top view of a gear wheel as shown in FIG. 2.
Wie sich aus den Fig. 5 und 6 ergibt, sind durch entsprechende Ausnehmungen in den Schalen 1 und 2 Kanäle 11 gebildet, in denen eine (nicht gezeigte) Kette läuft, die die beiden Zahnräder 8 miteinander verbindet. Die Kanäle können da¬ bei entweder durch spanende Bearbeitung oder durch entsprechendes Verformen hergestellt sein. 5As can be seen from FIGS. 5 and 6, channels 11 are formed by corresponding recesses in the shells 1 and 2, in which a chain (not shown) runs which connects the two toothed wheels 8 to one another. The channels can be produced either by machining or by appropriate shaping. 5
Die Fig. 7 und 8 zeigen ein weiteres Ausführungsbeispiel einer horizontalen" Verlängerung für Betätigungswerkzeuge mit Vierkantantrieb, wobei hier eine gekröpfe Version dargestellt ist. Diese unterscheidet sich von der geraden Ver¬ längerung durch zwei unterschiedliche Abwinklungen im Schaft 5 und dadurch, daß zur optimalen Nutzung beide Zahnräder 8 mit einer Vierkantöffnung 6 aus¬ gestattet sind. Die Steckschlüsselaufnahme geschieht hierbei mit Hilfe von Vier¬ kantverbindungsstücken, die als handelsübliches Zubehör für Betätigungswerk¬ zeuge erhältlich sind. 7 and 8 show a further exemplary embodiment of a horizontal " extension for actuating tools with square drive, a cranked version being shown here. This differs from the straight extension by two different bends in the shaft 5 and in that for optimum use both gear wheels 8 are equipped with a square opening 6. The socket wrench is taken up here with the aid of square connectors, which are available as commercially available accessories for actuating tools.
