Die Erfindung bezieht sich auf ein Mehrzweckgerät mit austauschbarem Werkzeug, insbesondere für den Berg- und / oder Eissport mit den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a multipurpose device with interchangeable tool, especially for mountain and / or ice sports with the characteristics of Preamble of claim 1.

Solche Mehrzweckgeräte sind bekannt (AT 377 917; EU-PS 77 769; AT 460 U1; DE 295 00 975 U1).Such multi-purpose devices are known (AT 377 917, EU-PS 77 769, AT 460 U1; DE 295 00 975 U1).

Insbesondere ist in diesem Zusammenhang auf die FR 2 351 761 A zu verweisen, die ein Mehrzweckgerät vergleichbarer Bauart zeigt und beschreibt. Der Werkzeugkopf ist als stehendes U-Profil ausgebildet, und im Steg dieses U-Profiles sind zwei Bohrungen vorgesehen, von welchen die eine Bohrung als Gewindebohrung und die andere Bohrung als Durchsteckbohrung vorgesehen ist. Die Stärke des Teiles des austauschbaren Werkzeuges, das von diesem Werkzeugkopf aufgenommen wird, ist kleiner als die innere Höhe des U-Profiles. Die hier vorhandene Höhendifferenz wird ausgeglichen durch eine Einlageplatte mit zwei Bohrungen, von denen die eine als Gewindebohrung und die andere Bohrung als Durchsteckbohrung zur Aufnahme eines Schraubenkopfes ausgebildet ist. Zur Festlegung des Werkzeuges sind im Werkzeugkopf zwei parallel zueinander liegende Schrauben vorgesehen, die in die genannten Gewindebohrungen eingedreht sind. Bei dieser Konstruktion ist das austauschbare Werkzeug durch das U-Profil positioniert. Für das Festziehen der Schraube sind Inbusschlüssel erforderlich. Die erwähnte Einlageplatte, die vom U-Profil aufgenommen ist, dient dabei als Mutter für die eine Schraube.In particular, reference should be made in this connection to FR 2 351 761 A, which shows and describes a multipurpose device of comparable design. Of the Tool head is designed as a standing U-profile, and in the web of this U-profile two holes are provided, of which the one hole as a threaded hole and the other bore is provided as a through hole. The Strength of the part of the replaceable tool used by this tool head is smaller than the inner height of the U-profile. This one existing height difference is compensated by an insert plate with two Holes, one of which as a threaded hole and the other hole as Through hole for receiving a screw head is formed. to Fixing the tool are two parallel to each other in the tool head Screw provided, which screwed into said threaded holes are. In this construction, the interchangeable tool is through the U-profile positioned. Hex wrenches are required to tighten the screw. The mentioned insert plate, which is received by the U-profile, serves as a mother for the one screw.

Auch die US 4 476 597 A zeigt und beschreibt ein Mehrzweckgerät. Hier wird der Werkzeugkopf durch einen aus Blech gebogenen U-Teil gebildet, wobei der Stiel des Gerätes zwischen den beiden Wangen dieses U-Teiles liegt. Die austauschbaren Werkzeuge werden in die beiden offenen Seiten des U-Teiles eingesteckt und hier mittels Schrauben und Muttern festgelegt. Die Spannkraft dieser Schrau ben preßt die Wangen des U-Teiles zusammen, zwischen welchen die Werkze ge liegen. Also, US 4,476,597 A shows and describes a multifunction device. Here is the Tool head formed by a bent sheet metal U-part, wherein the stem of the device lies between the two cheeks of this U-part. The interchangeable ones Tools are inserted into the two open sides of the U-part and fixed here by means of screws and nuts. The elasticity of this screw ben presses the cheeks of the U-part, between which the tools ge lie.

Schlußendlich ist noch der Eispickel nach der DE 34 42 933 A1 zu erwähnen. Hier ist der mit dem Stiel verbundene Werkzeugkopf, der gleichzeitig als Hammer ausgebildet ist, geschlitzt gestaltet, wobei die beiden diesen Schlitz begrenzenden Wangen fluchtende Bohrungen aufweisen mit gezahntem Innenrand. In diesen Schlitz wird das austauschbare Werkzeug eingesteckt, das in seinem vom Werkzeugkopf aufnehmenden Teil eine zu den erwähnten Bohrungen korrespondierende Bohrung mit gezahnten Rändern besitzt. Sind Werkzeugkopf und Werkzeug zusammengesteckt, so wird in die erwähnten, deckungsgleich liegenden Bohrungen ein gezahnter Bolzen eingesteckt, der eine zentrale Gewindebohrung aufweist zur Aufnahme einer Spannschraube und der endseitig einen Anschlagbund besitzt. Durch das Anziehen der Schraube wird das Werkzeug mit dem Werkzeugkopf verspannt. Der Fertigungsaufwand für diesen Eispickel ist relativ hoch, was sich auch im Preis für dieses Werkzeug niederschlägt, so daß dieses Werkzeug bislang keinen Eingang auf dem Markt hat finden können.Finally, the ice pick according to DE 34 42 933 A1 should be mentioned. Here is the tool head connected to the handle, which is also a hammer is formed slotted designed, the two limiting this slot Cheeks have aligned holes with serrated inner edge. In these Slot is plugged in the replaceable tool used in his vom Tool head receiving part corresponding to the holes mentioned Has bore with toothed edges. Are tool head and tool put together, is in the mentioned, congruent Holes a toothed bolt inserted, the central threaded hole has for receiving a clamping screw and the end a stop collar has. By tightening the screw, the tool with the Tool head clamped. The manufacturing cost of this ice ax is relative high, which is also reflected in the price of this tool, so this Tool so far has no entrance on the market can find.

Das Mehrzweckgerät besitzt einen Stiel 1, der hier nicht weiters dargestellt ist und an dessen oberem Ende ein Werkzeugkopf 2 festgelegt ist. Dieser Stiel ist herkömmlich gestaltet. Er kann einen runden Querschnitt haben oder einen vieleckigen oder einen Querschnitt, der zwischen diesen beiden Formen liegt. Der Werkzeugkopf 2 ist platten- oder scheibenartig ausgebildet und besitzt zwei ebene, zueinander parallele Anlageflächen 3, 4. In diesem Werkzeugkopf 2 sind zwei nebeneinander liegende Durchsteckbohrungen 5 sowie zwei übereinander liegende, schlitzförmige Öffnungen 6, letztere für die Aufnahme einer Handschlaufe, vorgesehen. Auf diese schlaufenförmigen Öffnungen 6 wird im folgenden nicht weiter eingegangen werden, da sie die Erfindung nicht unmittelbar berühren.The multipurpose device has a handle 1, which is not shown here and further at the upper end of a tool head 2 is fixed. This stalk is conventional designed. It can have a round cross section or a polygonal one or a cross section that lies between these two forms. The tool head 2 is plate-like or disk-like and has two plane, mutually parallel contact surfaces 3, 4. In this tool head 2 are two adjacent through-holes 5 and two superimposed, slit-shaped openings 6, the latter for receiving a wrist strap, intended. On these loop-shaped openings 6 is not in the following be further discussed, since they do not touch the invention directly.

Zwei Werkzeuge, nämlich eine Haue 8 und eine Schaufel 9, wie sie beispielsweise zusammen mit dem Werkzeugkopf 2 verwendet werden, sind in den Fig. 7 bis 10 dargestellt. Unabhängig von der Art des Werkzeuges selbst ist für dieses wesentlich, daß es einen laschenartigen Anlageteil 7 besitzt mit einer schlüssellochartigen Ausnehmung 10. Diese weist einen länglichen Abschnitt auf, der endseitig im vorliegenden Fall in eine sechskantige Erweiterung übergeht.Two tools, namely a haul 8 and a blade 9, as for example are used together with the tool head 2 are shown in Figs. 7 to 10 shown. Regardless of the type of tool itself is for this essential that it has a tab-like system part 7 with a keyhole-like Recess 10. This has an elongated portion, the end in the present case merges into a hexagonal extension.

Zu einem Werkzeugkopf 2 können außer Haue 8 und Schaufel 9 noch andere Werkzeuge vorgesehen werden bzw. können Haue und Schaufel unterschiedlich gestaltet sein. Alle diese zu einem Werkzeugkopf 2 gehörenden Werkzeuge werden als Werkzeugsatz angesehen. Die in den laschenartigen Anlageteilen 7 vorgesehenen schlüssellochartigen Ausnehmungen 10 eines zu einem Mehrzweckgerät gehörenden Werkzeugsatzes sind dabei so angeordnet, daß die Erweiterung der Ausnehmung 10 auf der Seite des eigentlichen Werkzeuges oder diesem Werkzeug abgewandt liegt. Dies ist in den Fig. 7 und 9 veranschaulicht.To a tool head 2 except Haue 8 and 9 bucket other Tools can be provided or handle and shovel different be designed. All of these tools belonging to a tool head 2 become viewed as a toolkit. The measures provided for in the tab-like plant parts 7 keyhole-like recesses 10 a to a multi-purpose device belonging tool set are arranged so that the extension the recess 10 on the side of the actual tool or this Tool facing away. This is illustrated in FIGS. 7 and 9.

In die Durchsteckbohrungen 5 des Werkzeugkopfes 2 (Fig. 4 bis 6) werden Kopfschrauben11 eingesteckt, und zwar zweckmäßigerweise solche handelsüblicher Größe und Form und in der Weise, daß die Köpfe 12 der beiden Kopfschrauben 11 auf verschiedenen Seiten des Werkzeugkopfes 2 liegen. Diese Kopfschrauben 11 sind zweckmäßigerweise am Werkzeugkopf 2 beispielsweise durch eine Verschweißung oder Verklebung festgelegt. Diese Verbindung (Verschweißen oder Verkleben) zwischen Werkzeugkopf 2 und Kopfschrauben 11 wird herstellerseitig vorgenommen, so daß Werkzeugkopf 2, Gewindebolzen und Erhebung einen einheitlichen Bauteil bilden. Die Köpfe 12 bilden nun die Erhebung, die von der Erweiterung der schlüssellochartigen Ausnehmung 10 aufgenommen wird, wenn das Werkzeug montiert ist. Die Weite W des länglichen Abschnittes der Ausnehmung 10 entspricht dem Durchmesser des Gewindebolzens der Kopfschraube 11. Es liegt im Rahmen der Erfindung, anstelle von Kopfschrauben handelsüblicher Größe und Form Spezialschrauben hier einzusetzen.In the through-holes 5 of the tool head 2 (Fig. 4 to 6) head screws 11 inserted, and expediently such commercial Size and shape and in such a way that the heads 12 of the two capscrews 11 lie on different sides of the tool head 2. These capscrews 11 are expediently on the tool head 2, for example by welding or gluing. This connection (welding or Gluing) between the tool head 2 and cap screws 11 is the manufacturer made so that the tool head 2, threaded bolt and survey a form a single component. The heads 12 now form the elevation, of the Extension of the keyhole-like recess 10 is received, if the tool is mounted. The width W of the elongated portion of the recess 10 corresponds to the diameter of the threaded bolt of the cap screw 11. It is within the scope of the invention, commercially available instead of capscrews Size and shape Use special screws here.

Die Fig. 11 bis 13 zeigen die am Werkzeugkopf 2 festgelegten beiden Werkzeuge 8 und 9 in verschiedenen Ansichten. Zur Demontage der Werkzeuge werden die auf die Gewindebolzen der Kopfschrauben 11 aufgeschraubten Hutmuttem so weit hochgedreht, daß sie von der Oberfläche des Kopfes 12 der benachbart liegenden Kopfschraube einen Abstand A aufweisen, der zumindest der Stärke S des laschenartigen Anlageteiles 7 entspricht. Nun kann das Werkzeug von der Anlagefläche 3 bzw. 4 des Werkzeugkopfes 2 abgehoben werden, und zwar so weit, daß die Erweiterung der schlüssellochartigen Ausnehmung 10 außer Wirkverbindung mit dem Kopf 12 der benachbart liegenden Kopfschraube 11 gelangt. Nun wird das Werkzeug seitlich etwas versetzt, so daß die Erweiterung der Ausnehmung 10 und die hochgedrehte Hutmutter 13 deckungsgleich liegen, worauf das Werkzeug abgehoben werden kann. Die Montage wickelt sich in umgekehrter Reihenfolge ab. Zur Betätigung der Mutter 13, sowohl zum Lösen wie auch zum Festziehen, dient ein Werkzeug des Werkzeugsatzes, das zu diesem Mehrzweckgerät gehört.FIGS. 11 to 13 show the two tools fixed to the tool head 2 8 and 9 in different views. To disassemble the tools are the on the threaded bolts of the cap screws 11 screwed Hutmuttem so turned up far enough that they are from the surface of the head 12 of the adjacent Head screw have a distance A, at least the strength of S. corresponds to the tab-like system part 7. Now the tool of the Contact surface 3 and 4 of the tool head 2 are lifted, and so far, that the extension of the keyhole-like recess 10 out of operative connection with the head 12 of the adjacent head screw 11 passes. Now the tool is laterally offset slightly, so that the extension of the recess 10 and the turned-up cap nut 13 are congruent, whereupon the tool can be lifted off. The assembly winds in reverse Order from. For actuating the nut 13, both for loosening as well as for Tightening, a tool of the tool kit that serves to this multifunction device belongs.

Die Fig. 14 bis 16 zeigen Ansichten verschieden gestalteter Werkzeugköpfe, die sich voneinander im wesentlichen dadurch unterscheiden, daß die schlitzförmigen Öffnungen 6 gegenüber den Durchsteckbohrungen 5 unterschiedlich angeordnet sind.Figs. 14 to 16 are views of differently shaped tool heads, the Essentially differ from each other in that the slot-shaped Openings 6 opposite to the through-holes 5 arranged differently are.

Vorstehend ist eine besonders zweckmäßige Ausgestaltung der Erfindung gezeigt und beschrieben. Eine vereinfachte Ausgestaltung besteht beispielsweise darin, daß der Werkzeugkopf 2 nur eine Anlagefläche besitzt. Zur Verdrehsicherung kann auch ein einfacher Bolzen angeordnet werden und anstelle einer einzigen schlüssellochartigen Ausnehmung sind nun im Anlageteil 7 zwei Bohrungen angeordnet, was allerdings die Handhabung gegenüber der vorstehend beschriebenen Ausführungsform erschwert, da in einem solchen Fall beim Werkzeugwechsel die Hutmutter stets abgenommen werden muß. Die Erhebung zur Verdrehsicherung kann eine Umfangskontur besitzen, die von der Rotationssymmetrie abweicht, und auf dieser Erhebung selbst kann ein Gewindebolzen festgelegt sein. Gewindebolzen und Verdrehsicherung oder auch die Durchsteckbohrungen 5 können übereinander angeordnet werden. Alle diese Ausführungsformen sind zwar einfach und damit ohne besonderen Aufwand herstellbar, jedoch ist ihre Handhabung gegenüber dem ausführlich anhand der Zeichnung geschilderten Ausführungsbeispiel erschwert, da in all diesen Fällen die Hutmutter abgenommen werden muß, wenn das Werkzeug gewechselt wird. Dadurch, daß die Ausnehmung 10 schlüsselloch-artig ausgebildet wird, genügt es, daß zum Wechseln der Werkzeuge die Hutmutter nur hochgedreht wird, ohne daß sie vom Gewindebolzen abgenommen werden muß. Vorstehend ist von Hutmuttern die Rede. Es liegt im Rahmen der Erfindung, anstelle einer solchen Hutmutter auch einfache Muttern zu verwenden. Die Werkzeugköpfe 2 der vorstehend gezeigten Ausführungsbeispiele besitzen zueinander parallele Anlageflächen 3 und 4. Es ist denkbar, daß anstelle eines solchen plattenartigen Elementes mit parallelen Anlageflächen 3 und 4 für den Werkzeugkopf 2 dieser als keilartiges Element ausgebildet ist, wobei in diesem Falle die Anlageflächen miteinander und mit der Achse des Stieles des Werkzeuges einen spitzen Winkel einschließen. Bei einem solchen keilartigen Element ist auch eine Ausgestaltung möglich, bei der eine Anlagefläche einen spitzen Winkel mit der Achse des Stieles einschließt und die andere Anlagefläche parallel zur Achse des Stieles liegt. Die Ausgestaltung des Werkzeugkopfes 2 in der vorstehend erörterten Art ist vorwiegend abhängig von der Art des Werkzeuges, das mit dem Werkzeugkopf verbunden werden soll. Above, a particularly advantageous embodiment of the invention is shown and described. A simplified embodiment, for example in that the tool head 2 has only one contact surface. To prevent rotation Also, a simple bolt can be arranged and instead of a single one keyhole-like recess are now in the system part 7 two holes arranged, however, the handling over the above-described Embodiment complicates, since in such a case, the tool change the cap nut must always be removed. The survey for anti-rotation may have a circumferential contour that depends on the rotational symmetry deviates, and on this survey itself can set a threaded bolt his. Threaded bolt and anti-rotation device or the through-holes 5 can be arranged one above the other. All of these embodiments are Although easy and thus produced without any special effort, but is their Handling compared to the detail described with reference to the drawing Embodiment difficult because in all these cases, the cap nut removed must be when the tool is changed. Due to the fact that the recess 10 keyhole-like design, it is sufficient that to change the tools the cap nut is only turned up without them from the threaded bolt must be removed. The above is talked about cap nuts. It is within the scope of the invention, instead of such a cap nut also simple To use nuts. The tool heads 2 of the embodiments shown above have mutually parallel contact surfaces 3 and 4. It is conceivable that instead of such a plate-like element with parallel contact surfaces 3 and 4 for the tool head 2 of this formed as a wedge-like element is, in which case the abutment surfaces with each other and with the axis of the handle of the tool at an acute angle. In such a Wedge-like element is also an embodiment possible in which a contact surface includes an acute angle with the axis of the stem and the other Contact surface is parallel to the axis of the stem. The design of the Tool head 2 in the manner discussed above is mainly dependent on the type of tool to be connected to the tool head.
