Description

Die Erfindung bezieht sich auf einen Griff für ein Handwerkzeug, insbesondere Schraubendrehergriff, nach dem Oberbegriff des Anspruchs 1, wie er z.B. für diverse Schraubarbeiten Verwendung findet.The invention relates to a handle for a hand tool, especially screwdriver handle, according to Preamble of claim 1 as e.g. for various Screwing work is used.

Es ist bekannt, Schraubendrehergriffe zu verwenden, an deren einen Stirnseite z.B. über eine Spannmuffe, unterschiedliche Werkzeugeinsätze bzw. Werkzeugschäfte mit diversen aktiven Teilen, z.B. Stützschrauber, Kreuzschlitzschrauber, Sechskant/Imbus austauschbar befestigbar ist. Diese Griffe sind in Verbindung mit an sich bekannten Werkzeugenkästen, insbesondere Ratschenkästen, die verschiedene Nüsse und Bits enthalten, nicht verwendbar. Zudem können sie jeweils nur in ihrer klassischen Form als Schraubendreher verwendet werden, also für weniger kraftaufwendige Schraubarbeiten, während für größere Drehmomente zu einem T-Griff oder in platzbegrenzten Situationen zu einem Revolvergriff ausgewichen werden muß. Es sind somit jeweils für drei unterschiedliche Arbeitssituationen drei unterschiedliche Werkzeuge bereitzustellen.It is known to use screwdriver handles one end face e.g. via a clamping sleeve, different Tool inserts or tool shanks with various active parts, e.g. Support screwdriver, Phillips screwdriver, Hexagon / Allen key is interchangeably attachable. These handles are in connection with known Tool boxes, especially ratchet boxes, the various Contains nuts and bits, cannot be used. moreover can only be used in their classic form as Screwdriver can be used, so for less effort Screwdriving work while for larger torques to a T-handle or in space-limited situations a revolver grip must be avoided. So there are three each for three different work situations to provide different tools.

Zwar ist aus der DE-C-36 36 025 ein Schraubendrehergriff bekannt, bei dem ein Werkzeugzubehörteil, wie Inbusschlüssel, in zwei verschiedenen Einstellungen am Griffteil befestigbar ist und zwar in einer längsaxialen Position und einer zu dieser senkrechten, mittigen Position, wodurch sich ein T-Griff ergibt. Für diese verschiedenen Anordnungsweisen weist der Werkzeugeinsatz ein Kopfteil auf, der in einem entsprechenden Schlitz des Griffes in unterschiedlichen Positionen schiebeinsteckbar ist. Abgesehen davon, daß mit diesem bekannten Griff lediglich eine normale Schraubendreherfunktion und eine T-Schrauberfunktion erreicht werden kann, ist er zudem nicht für weitere handelsübliche Werkzeugeinsätze verwendbar, da nur Werkzeugeinsätze mit dem speziellen, für diesen Griff ausgelegten Kopf verwendbar sind.DE-C-36 36 025 is a screwdriver handle known in which a tool accessory, such as an Allen key, Can be attached to the handle in two different settings is in a longitudinal axial position and one too this vertical, central position, which creates a T-handle results. For these different ways of arrangement points the tool insert has a head part that is in a corresponding Slit of the handle in different positions is insertable. Apart from that with this known handle just a normal screwdriver function and a T screwdriver function can be achieved it is also not for other commercially available tool inserts usable as only tool inserts with the special designed for this handle can be used.

Schließlich zeigt die US-A-3,850,056 ein Schraubwerkzeug, dessen Griffkörper ebenfalls einen eine axiale Bohrung und einen axial-radialen Schlitz aufweist, in die bekannte, handelsübliche L-förmige Schraubwerkzeuge, allgemein unter Allen-Schraubendreher bekannt, mit Hilfe von auf den Längenschenkel des L-Schraubendrehers aufgeschobene Muffe, eingesetzt wird. Dabei ragen die beiden Schenkelenden des L-Werkzeugs jeweils axial bzw. radial aus dem Griffkörper heraus, so daß ein Kombinationswerkzeug bereitgestellt ist, das sowohl als normaler Schraubendreher, als auch als T-Griff-Schraubendreher verwendet werden kann. Abgesehen davon, daß stets beide Werkzeugschenkel aus dem Griff herausragen und bei der jeweiligen Arbeit hinderlich sein können, ist dieses bekannte Werkzeug auch jeweils nur in Kombination des leeren Griffkörpers mit Muffen und L-förmigen Werkzeugen verwendbar. Handelsübliche Werkzeuge bzw. Einsätze, Nüsse, Bits, Ratschen usw. können nicht in Kombination mit diesem Werkzeug bzw. dem Griffkörper dieses Werkzeugs verwendet werden, wodurch dessen Einsetzbarkeit sehr begrenzt ist.Finally, US-A-3,850,056 shows a screwing tool whose handle body also has an axial bore and has an axial-radial slot into the known, commercially available L-shaped screwing tools, generally under Allen screwdriver known, with the help of on the long legs of the L screwdriver, inserted sleeve becomes. The two leg ends of the L tool protrude axially or radially out of the handle body, so that a combination tool is provided that both as a normal screwdriver and as a T-handle screwdriver can be used. Apart from that always protrude both tool legs from the handle and can be a hindrance in the respective work, this is known tool only in combination of the empty Handle body can be used with sleeves and L-shaped tools. Commercial tools or inserts, nuts, bits, ratchets etc. cannot be used in combination with this tool or the Handle body of this tool can be used, which its applicability is very limited.

Aufgabe der Erfindung ist es, einen Griff o.g. Gattung anzugeben, der es ermöglicht, diesen in mindestens zwei unterschiedlichen Schraub-Arbeitspositionen, also mindestens als Schraubendreher und als T-Griff-Schrauber zu verwenden, in schneller Kombination, mit handelsüblichen Werkzeugen bzw. Einsätzen, Nüssen, Bits, Ratschen usw. und der zudem einen einfachstmöglichen Aufbau aufweist.The object of the invention is a handle o.g. genus specify that it can be divided into at least two different screwing work positions, at least as a screwdriver and as a T-handle screwdriver use, in quick combination, with commercially available Tools or inserts, nuts, bits, ratchets etc. and which also has the simplest possible structure.

Diese Aufgabe wird durch einen gattungsgemäßen Griff mit den Merkmalen des Anspruchs 1 gelöst. In den abhängigen Ansprüchen 2-15 sind vorteilhafte Ausgestaltungen angegeben.This task is carried out with a generic handle solved the features of claim 1. In dependent claims 2-15 advantageous configurations are specified.

Demgemäß weist der erfindungsgemäße Griff als Vorkehrungen zum Befestigen der diversen Werkzeugeinsätze an seinem Griffkörper mindestens zwei Mehrkant-Aufnahmezapfen auf, auf die die bekannten Werkzeugeinsätze über ihre Aufnahmemuffen aufsteckbar angebracht werden können. Dabei ist ein erster Zapfen an einer Stirnseite des Werkzeugkörpers koaxia1 in Längsausrichtung hervorragend angeordnet, während mindestens ein weiterer, winkelig zum ersten Zapfen ausgerichteter und zu diesem beabstandeter Zapfen, vorgesehen ist. Hierdurch ist in einfacher Weise ein Vielfach- bzw. Multigriff realisiert worden, der in Kombination mit am Markt preiswert angebotenen Zubehörteilen schnell und einfach, ohne besondere Klemmvorkehrungen oder Spezialausführungen, einen multifunktionalen Schraubendreher darstellt.Accordingly, the handle of the invention has precautions to attach the various tool inserts to his Handle body at least two polygonal mounting pins, to the well-known tool inserts via their receiving sleeves can be attached attachable. There is one first pin on an end face of the tool body koaxia1 superbly aligned in the longitudinal direction while at least one further one, oriented at an angle to the first pin and to this spaced pin provided is. As a result, a multiple or Multi handle has been realized, which in combination with Quickly and easily, cheaply offered accessories, without special clamping arrangements or special designs, represents a multifunctional screwdriver.

Besonders vorteilhaft ist, wenn am Griffkörper drei Aufnahmezapfen vorgesehen sind, wobei zusätzlich zum ersten, längsaxial herausragenden Zapfen ein zweiter Zapfen senkrecht zur Längsachse und somit zum ersten Zapfen und gleichzeitig mittig zur Längserstreckung des Griffes, angeordnet ist. Hierdurch kann der Griff als T-Griff verwendet werden. Zudem ist ein dritter Zapfen in der Zone der dem ersten Zapfen entgegengesetzten Stirnseite des Griffes angeordnet und zwar in einem Winkel von 90 bis 120° zur Ausrichtung des ersten Zapfens bzw. zur Griff-Längsachse, wodurch ein Revolvergriff bereitstellbar ist. Dabei ist besonders die 120°-Position vorteilhaft, in der der Zapfen im wesentlichen an der Stirnseitenkante mündet, wodurch ein Schräg-Revolvergriff mit besonders guter Arbeitsweise vorhanden ist. It is particularly advantageous if there are three locating pins on the handle body are provided, in addition to the first, protruding longitudinally axially, a second tenon vertically to the longitudinal axis and thus to the first pin and at the same time arranged centrally to the longitudinal extent of the handle is. This allows the handle to be used as a T-handle become. There is also a third spigot in the zone of face of the handle opposite the first pin arranged at an angle of 90 to 120 ° to Alignment of the first pin or to the longitudinal axis of the handle, whereby a revolver grip can be provided. It is especially the 120 ° position advantageous in which the pin essentially opens at the front edge, whereby an inclined revolver grip with a particularly good working method is available.

Der somit als einfacher Schraubendreher, als T- und als Revolvergriff einsetzbare, erfindungsgemäße Multigriff kann aufgrund der verschiedenen Einsatzmöglichkeiten für unterschiedliche Drehmomente bedarfsweise eingesetzt werden. Auch kann zusätzlich direkt oder über einen kleinen Adaptersteckteil ein Ratschenelement, z.B. eine Freilaufratschennuß gemäß DE-U-297 23 472, verwendet werden, wobei dann an diese Ratsche die Werkzeugeinsätze bedarfsweise ansteckbar sind. Somit kann der Griff in allen drei Verwendungspositionen als Ratschengriff, in Verbindung mit den verschiedensten Werkzeugeinsätzen, Verwendung finden. Der Griff kann somit zusammen mit entsprechenden Zubehörteilen zu einem Set zusammengesetzt werden, z.B. in einem entsprechenden Werkzeugkasten, der neben dem Schraubendrehergriff mindesten ein Ratschenelement, verschiedene Verlängerungen, Nüsse, Bits usw. enthalten kann.So as a simple screwdriver, as a T and Revolver grip usable multi-grip according to the invention can be used for different torques can be used as required. Also can be done directly or via a small one Adapter plug part a ratchet element, e.g. a freewheel ratchet nut according to DE-U-297 23 472, are used, wherein then the tool inserts to this ratchet if necessary are contagious. So the handle can be in all three Use positions as ratchet handle in connection with a wide variety of tool inserts. The handle can be used together with the corresponding accessories can be assembled into a set, e.g. in one corresponding toolbox that next to the screwdriver handle at least one ratchet element, various Extensions, nuts, bits, etc. may contain.

Von Vorteil ist, wenn die Zapfen jeweils ein an sich bekanntes Vielkantprofil aufweisen, wie Vierkant- oder Sechskantprofil, die mit den entsprechenden Vierkant- oder Sechskantinnenprofilen der Aufnahmemuffen der Werkzeugeinsätze oder entsprechender Verlängerungen oder Adapterteilen, zusammenwirken. Es ist selbstverständlich, daß bei Anordnung von Vierkantaufnahmezapfen in einem entsprechenden Werkzeugset mindestens ein Vierkant-/Sechskant-Adapterteil vorgesehen ist, um mit dem gleichen Griff Werkzeugeinsätze mit unterschiedlichen Aufnahmemuffen optimal verwenden zu können. It is advantageous if the cones are each known Have polygonal profile, such as square or Hexagonal profile with the corresponding square or Hexagon internal profiles of the socket sleeves of the tool inserts or corresponding extensions or adapter parts, interact. It goes without saying that at Arrangement of square mounting pins in a corresponding Tool set at least one square / hex adapter part is provided to tool inserts with the same handle optimal with different receiving sleeves to be able to use.

Dabei können die Zapfen am Griffkörper mehr oder weniger versenkt bzw. herausragend angeordnet sein. So können sie komplett aus der Griffaußenfläche herausragen, wobei die jeweils freistehende Zapfenlänge nur geringfügig größer als die Tiefe der Profilaufnahme der Muffe der Werkzeugeinsätze sein sollte.The pins on the handle body can more or less sunk or arranged outstanding. So you can protrude completely from the outer surface of the handle, whereby the each free-standing tenon length is only slightly larger than the depth of the profile socket of the sleeve of the tool inserts should be.

Die Zapfen können aber auch ganz oder teilweise im Griff versenkt sein, wobei um die Zapfen im Körper jeweils eine koaxiale, zylindrische Ausnehmung zum Einführen der Werkzeugaufnahme-Muffen vorgesehen sind. Dabei ist besonders vorteilhaft und bei der Handhabung günstig, wenn alle drei Zapfen ganz im Griff versenkt sind oder zumindest die beiden in die Außenmantelfläche des Griffes sich öffnenden bzw. ragenden Zapfen für die T- und Revolverpositionen. So wird insbesondere in der Verwendung des Griffes als klassischer Schraubendrehergriff, beim Drehen des Griffes um seine Achse, die Hand sich nicht an den hervorstehenden Zapfen einhängen, so daß Verletzungen vermieden werden. Der axiale Zapfen kann dabei ohne weiteres auch aus der Fläche teilweise oder ganz herausragend angeordnet sein, da dieser Zapfen bei der Handhabung des Griffes nicht weiter störend wirkt.The pins can also be fully or partially under control be sunk, one around each of the pins in the body coaxial, cylindrical recess for inserting the Tool holder sleeves are provided. It is special advantageous and inexpensive to handle if all three pins are completely sunk in the handle or at least the both opening into the outer surface of the handle or projecting pins for the T and turret positions. So is particularly classic in the use of the handle Screwdriver handle when turning the handle around its axis, the hand does not stick to the protruding one Hang the pin so that injuries are avoided. The axial pin can also be easily from the Area be partially or completely protruding, since this pin does not move any further when handling the handle is disturbing.

Der Griff kann erfindungsgemäß insgesamt einstückig ausgeführt sein, also im bzw. am Griffkörper sind die Zapfen ein- bzw. angeordnet und werden z.B. gleich bei Fertigung des Griffkörpers mit angegossen oder nachträglich herausgearbeitet. According to the invention, the handle can be made in one piece be in the handle body or the pins arranged or arranged and are e.g. right at the manufacturing stage of the handle body with cast or subsequently worked out.

Der Griffkörper kann jedoch auch aus Kunststoff, Hartgummi, Aluminiumguß oder anderem form-, spritz-, gieß- oder sinterbarem Material gefertigt sein, wobei die Zapfen aus Stahl- oder Gußmaterial gefertigt und in dem Griffmaterial drehfest eingebettet sind.However, the handle body can also be made of plastic, hard rubber, Cast aluminum or other form, injection, casting or sinterable material, the pins made of Steel or cast material made and in the handle material are embedded in a rotationally fixed manner.

Von Vorteil ist, wenn die aus handelsüblichen Vielkantprofilen, wie Vierkant- oder Sechskant-Profilen hergestellten Zapfen in Form von mindestens zwei Zapfen aufweisenden Vielkant-Einlegern und/oder als einzelne Vielkant-Einsätze im Griffkörper eingebettet sind.It is advantageous if the made of commercially available polygonal profiles, like square or hexagonal profiles Cones in the form of at least two cones Polygonal inserts and / or as individual Polygonal inserts are embedded in the handle body.

Dabei können drei einzelne Zapfen-Einsätze vorgesehen sein, die jeweils ein Vielkant-Zapfenende und ein Verankerungsende aufweisen, wobei das Verankerungsende eine flach breitgeschlagene oder axial schwalbenschwanzförmig aufgetrennte bzw. aufgeschnittene und auseinandergedrückte Form aufweist. Durch das flache Breitende oder das auseinandergespreizte Schwalbenschwanzende findet eine gute dreh- und schiebefeste Verankerung des Zapfens im Körpermaterial statt.Three individual tenon inserts can be provided be, each a polygon pin end and an anchoring end have, the anchoring end a flat broad-cut or axially dovetailed or cut open and pressed apart form having. By the flat broad end or the spread apart Dovetail end finds a good turning and non-slip anchoring of the pin in the body material instead of.

Es kann jedoch auch ein einziger, einteiliger Zapfen-Einleger vorgesehen sein, mit drei Zapfen, wobei in Stahlprofil-Ausführung, jeweils zwei Zapfen an einer entsprechend gebogenen, handelsüblichen Profilstange vorgesehen sind, während der dritte Zapfen an einer zweiten Profilstange vorgesehen ist, die an der ersten, gebogenen Profilstange durch Kleben, Schweißen o.ä., befestigt ist. However, it can also be a single, one-piece pin insert be provided with three pins, wherein in Steel profile version, each with two pins on one curved, commercially available profile rod provided are, while the third pin on a second profile bar is provided on the first, curved Profile rod is attached by gluing, welding or the like.

Sinnvoll ist hier, wenn der lange Teil, d.h. der den axialen Zapfen und den am entgegengesetzten Ende befindlichen 90°- bzw. 120°-Zapfen tragende Profilstange eine durchgehend, nur am 120°-Teil gebogene Profilstange ist, während der mittige T-Zapfen eine kurze Stange ist, die an der langen Stange angeschweißt ist. Dabei kann in Höhe des T-Zapfens in der langen Profilstange eine Quernut eingearbeitet sein, in die das innere Ende der kurzen Profilstange formschlüssig eingreift und durch Punktschweißen von der Rückseite her eine Schweißverbindung realisiert werden. So ist zudem eine optimale Drehsicherung vorhanden.It makes sense here if the long part, i.e. the axial Cones and the one at the opposite end 90 ° or 120 ° peg-bearing profile bar a continuous, is only on the 120 ° part bent profile rod, while the central T-spigot is a short rod that is on the long rod is welded on. It can amount to T-pin incorporated a transverse groove in the long profile bar into which the inner end of the short profile bar engages positively and by spot welding a welded connection from the rear become. So there is also an optimal rotation lock.

Es kann jedoch auch eine kürzere, an beiden Ende gebogene Profilstange vorgesehen sein, die den T-Zapfen und den Revolver-Zapfen aufweist, während der axial weisende Schraubendreher-Zapfen ein Einzel-Einsatz ist. Somit sind die stärker drehmomentbelasteten Zapfen, also der T- und der Revolverzapfen optimal belastbar im Körper verankert, während der weniger belastbare Einzel-Einsatz in der Schraubendreher-Position vorgesehen ist, die ein geringeres Drehmoment aufnehmen muß.However, it can also be a shorter one, curved at both ends Profile rod can be provided, the T-pin and the Revolver pin has, while the axially pointing Screwdriver tenon is a single use. So are the more torque-loaded pins, i.e. the T and the turret is optimally anchored in the body, while the less resilient single use in the Screwdriver position is provided, which is a lesser Torque must absorb.

Zur sicheren Aufnahme der Werkzeugeinsätze sind an den Griffzapfen in an sich bekannter Weise jeweils Arretiervorrichtungen, wie federbelastete Kugel oder Bolzen radial eingelassen, die mit entsprechenden Ausnehmungen in den Werkzeugeinsatz-Muffen zusammenarbeiten. To securely hold the tool inserts, the Grip pins each in a manner known per se, locking devices, like spring-loaded ball or radial pin embedded with the corresponding recesses in the Work tool insert sleeves together.

Schließlich besteht die Möglichkeit, den Griffkörper materialmäßig so auszugestalten, daß, insbesondere bei Anordnung von Einzel-Zapfeneinsätzen, in den entsprechenden Einsatzzonen eine Materialverstärkung vorgesehen ist, um in diesen Zonen eine höhere Festigkeit zu erreichen, wodurch ein Ausbrechen der Einzel-Zapfeneinsätze bei höherer Belastung vermieden wird.Finally, there is the possibility of materializing the handle body To be designed so that, especially when arranged of single tenon inserts, in the corresponding A material reinforcement is provided in order to to achieve higher strength in these zones, thereby a breakout of the single pin inserts at higher Load is avoided.

Nachfolgend wird die Erfindung anhand mehrerer Ausführungsbeispiele unter Bezug auf die Zeichnung näher erläutert.The invention is described below using several exemplary embodiments explained in more detail with reference to the drawing.

Wie aus Fig. 1 zu ersehen ist, besteht der erfindungsgemäße Griff 1 aus einem länglichen Griff-Körper 2, an dem drei Aufnahmezapfen 3, 4, 5 angeordnet sind. In der hier dargestellten ersten Ausführungsform sind die Zapfen 3, 4, 5 als Sechskantzapfen ausgebildet, die aus den Außenflächen des Griffkörpers in unterschiedlichen Positionen zueinander und zum Griffkörper, hervorragen. So ist an der einen Stirnseite 6 des Griffkörpers 2, koaxial zur KörperLängsachse 7, der Schraubendreher-Zapfen 3 angeordnet, während im wesentlichen mittig zur Körperlänge und gleichzeitig senkrecht auf die Körpermantelfläche sowie die Längsachse 7, der T-Zapfen 4 angeordnet ist. Zudem ist der Revolver-Zapfen 5 in der Stirnzone 8, also am entgegengesetzten Ende zur Stirnfläche 6 angeordnet und zwar im wesentlichen in gleicher Ebene mit den beiden anderen Zapfen 3 und 4, jedoch in einem Winkel von 120° zum Schraubendreher-Zapfen 3.As can be seen from Fig. 1, there is the inventive Handle 1 from an elongated handle body 2, on the three receiving pins 3, 4, 5 are arranged. In the here illustrated first embodiment are the pins 3, 4, 5 designed as a hexagon pin, which from the outer surfaces of the handle body in different positions to each other and to the handle body. So is the an end face 6 of the handle body 2, coaxial to the longitudinal axis of the body 7, the screwdriver pin 3 arranged while essentially centered to body length and at the same time perpendicular to the body surface as well as the Longitudinal axis 7, the T-pin 4 is arranged. In addition, the Revolver pin 5 in the front zone 8, so on the opposite Arranged end to end face 6 and essentially in the same plane with the other two pins 3 and 4, but at an angle of 120 ° to Screwdriver pin 3.

Bei der in Fig. 2 und 3 dargestellten Ausführungsform sind die drei Zapfen 3, 4, 5 als Vierkant-Zapfen ausgebildet, die zumindest teilweise im Griff eingelassen sind. Dabei sind die Zapfen 3, 4, 5 jeweils mit einer zu den Zapfen konzentrischen, zylindrischen Aussparung 9 umgeben, die bezüglich ihrer Tiefe davon abhängt, wie weit der Zapfen in dem Griffkörper eingesenkt ist, also in wie weit die Stirnfläche des Zapfens über die entsprechende Körperfläche heraussteht oder im Verhältnis zu dieser zurückgesetzt angeordnet ist. So ist hier der Zapfen 3 nur halb versenkt, während die Zapfen 4 und 5 ganz versenkt sind, sogar geringfügig tiefer als die Körper-Mantelfläche, um Verletzungen, insbesondere bei der Handhabung des Griffes als Schraubendrehergriff, zu vermeiden. Es ist zudem zu erkennen, daß in dem Ausführungsbeispiel nach Fig. 2 und 3 der Revolver-Zapfen 5 in einem Winkel von 90° zur Griff-Längsachse angeordnet ist, nahe der Stirnfläche 8.In the embodiment shown in Figs. 2 and 3 are the three pins 3, 4, 5 are designed as square pins, which are at least partially embedded in the handle. there are the pins 3, 4, 5 each with one to the pin concentric, cylindrical recess 9 surround the its depth depends on how far the spigot is sunk in the handle body, i.e. how far the Face of the pin over the corresponding body surface stands out or reset in relation to this is arranged. So here the pin 3 is only half sunk, while the pins 4 and 5 are completely sunk, even slightly deeper than the body surface area, um Injuries, especially when handling the handle as a screwdriver handle to avoid. It is also too recognize that in the embodiment of FIGS. 2 and 3 the turret pin 5 at an angle of 90 ° to the longitudinal axis of the handle is arranged near the end face 8.

In Fig. 2 und 3 sind zudem Werkzeugeinsätze 10, 11, 12 in koaxialer Einsatzrichtung zu den jeweiligen Zapfen zumindest andeutungsweise eingezeichnet und es ist zu erkennen, daß diese jeweils eine Aufnahmemuffe 13 aufweist, die ein Innenprofil entsprechend dem jeweiligen Zapfenprofil aufweist, wobei die Muffen-Profiltiefe 14 und die Zapfenprofil-Höhe 15 annähernd gleich sind. Zudem ist zu erkennen, daß das in Fig. 3 auf den Zapfen 4 über seine Muffe 13 aufzusetzende Ratschenelement 11 an der entgegengesetzten Stirnseite ebenfalls einen Aufnahmezapfen 16 aufweist, an dem z.B. Werkzeugeinsätze 10, 12 befestigbar sind, so daß ein T-Ratschen-Schrauber bereitgestellt wird. 2 and 3 there are also tool inserts 10, 11, 12 in at least coaxial direction of use to the respective pin hinted at and it can be seen that each has a receiving sleeve 13, the one Has an inner profile corresponding to the respective tenon profile, the sleeve profile depth 14 and the Pin profile height 15 are approximately the same. It is also too recognize that in Fig. 3 on the pin 4 on its Sleeve 13 ratchet element 11 to be placed on the opposite End face also a receiving pin 16 on which e.g. Tool inserts 10, 12 attachable are, so that a T-ratchet screwdriver is provided.

Bei den in Fig. 4 bis 6 dargestellten drei Ausführungsformen sind die im Griffkörper 2 angeordneten Zapfen 3, 4, 5 jeweils in gleicher Winkelposition (0°, 90°, 120°) zur Griff-Längsachse 7 angeordnet. Sie weisen jeweils eine Arretiervorrichtung 17 auf, die in an sich bekannter Weise z.B. aus einer radial eingelassenen, federbelasteten Kugel besteht. Alle drei Zapfen 3, 4, 5 sind dabei ganz versenkt vorgesehen und von jeweils gleichtiefen, konzentrischen Aussparungen 9 umgeben. Die Zapfen 3, 4, 5 sind an einem Vielkant-Einleger vorgesehen, der aus einer langen, nur an einem Ende in einem 120°-Winkel abgebogenen Profilstab 19 besteht, der bis auf den abgebogenen, kurzen Teil fast auf die ganze Länge koaxial zur Mittenachse 7 des Griffes angerichtet ist. Ein kurzer Profilstab 20, der einerseits den T-Zapfen 4 aufweist, ist mit seiner anderen Seite an dem langen Profilstab 19 im wesentlichen mittig so angeschweißt, daß die drei Zapfen 3, 4, 5 in der gleichen Mittenebene des Griffkörpers liegen.In the three embodiments shown in FIGS. 4 to 6 are the pins 3, 4 arranged in the handle body 2, 5 each in the same angular position (0 °, 90 °, 120 °) Handle longitudinal axis 7 arranged. They each have one Locking device 17 on, in a manner known per se e.g. from a radially recessed, spring-loaded ball consists. All three pins 3, 4, 5 are completely sunk provided and of equal depth, concentric Surround recesses 9. The pins 3, 4, 5 are on one Polygonal insert provided from a long, just to one end bent at a 120 ° angle profile bar 19 Exists, except for the short, bent part the entire length arranged coaxially to the central axis 7 of the handle is. A short profile bar 20, on the one hand has the T-pin 4 is with its other side the long profile bar 19 is essentially welded in the middle, that the three pins 3, 4, 5 in the same center plane of the handle body.

Bei der Ausführungsform nach Fig. 5 ist ein Zweizapfen-Einleger 21 vorgesehen, der aus einem U-Profilstab 22 besteht, an dessen beiden kurzen 90°- bzw. 120°-T-Schenkeln die Zapfen 4 bzw. 5 vorgesehen sind. Zudem ist ein Einzeleinsatz 23 koaxial an der in der Stirnseite 6 des Griffes eingesetzt, der an seinem einen Ende den Zapfen 3 und an seinem anderen Ende ein flach- bzw. breitgeschlagenes Verankerungsende 24 besitzt. Zur Anfertigung dieses Einzeleinsatzes kann ein kurzer Profilstab, z.B. ein Vierkantprofilstabstück verwendet werden, das an seinem einen Ende zum Verankerungsende 24 einseitig oder symmetrisch zweiseitig zusammengedrückt bzw. geschlagen wird, so daß ein schaufelförmiges Verankerungsteil entsteht. Das andere Ende ist mit einer Arretiervorrichtung 17 versehen und ragt in die konzentrische Aussparung 9 hinein, hier im wesentlichen bündig mit der Stirnfläche 6 abschließend. Es ist zu erkennen, daß der Einleger 21 über seine Zapfen 4, 5 ein größeres Drehmoment übernehmen kann, als der Einzel-Einsatz 23, der jedoch kein so hohes Drehmoment zu übernehmen braucht, da er lediglich den Schraubendreher-Zapfen 3 trägt.5 is a two-peg insert 21 is provided, which consists of a U-shaped bar 22, on its two short 90 ° or 120 ° T legs the pins 4 and 5 are provided. It is also a single assignment 23 coaxially on the front 6 of the handle used the pin 3 and at the other end a flat or broad-cut one Anchoring end 24 has. To make this single use a short profile bar, e.g. a square profile rod piece be used on his one End to the anchoring end 24 one-sided or symmetrical is compressed or beaten on two sides, so that a blade-shaped anchoring part is created. The other End is provided with a locking device 17 and protrudes into the concentric recess 9, here in essentially flush with the end face 6. It it can be seen that the insert 21 via its pins 4, 5 can take on a greater torque than that Single use 23, however, the torque is not so high need to take over, since he only the screwdriver pin 3 wears.

Schließlich ist aus Fig. 6 zu erkennen, wie in weiterer Ausführung im Griffkörper 2 drei Einzel-Einsätze 25 vorgesehen sind, die einen ähnlichen Aufbau aufweisen, wie der Einzel-Einsatz 23 aus Fig. 5. Unterschiedlich ist lediglich die Ausbildung des Verankerungsendes, das hier als schwalbenschwanzförmiges Verankerungsende 26 ausgebildet ist. Es ist dabei zu erkennen, daß das Verankerungsende 26 zwei auseinanderweisende Arme aufweist. Es können jedoch auch drei oder mehr Arme vorgesehen sein, so daß dann das Verankerungsende mehrere Verankerungszacken aufweist bzw. sternförmig aussieht. Diese Zacken können in der gleichen Ebene liegen, jedoch auch, z.B. durch Kreuzeinschnitt, diagonal gegenüberliegend aufgebogen sein. Das Verankerungsteil kann schließlich, in Annäherung an die Ausführungsform als Verankerungsende 24 gemäß Fig. 5 mindestens einseitig eingeschlagene Rillen aufweisen, die ein ungewolltes Herausreißen des Einsatzes verhindern. Finally, it can be seen from Fig. 6, as in another Version in handle body 2 three individual inserts 25 provided are of a similar structure as the individual insert 23 from FIG. 5 is only different the formation of the anchoring end, which here as dovetail-shaped anchoring end 26 is formed is. It can be seen that the anchoring end 26 has two arms pointing apart. However, it can also three or more arms may be provided, so that then Has several anchoring prongs or looks star-shaped. These spikes can be in the same Level, but also e.g. by cross-cutting, be bent diagonally opposite. The anchoring part can finally, in approximation to the embodiment at least as the anchoring end 24 according to FIG. 5 have grooves tucked in on one side, which are unwanted Prevent the insert from being torn out.
