Description

Die Erfindung betrifft einen Werkzeugstiel zur Anbringung an einem Werkzeuggriff, mit einem Verbinder, der einen Schaft zum Einstecken in einen Kanal eines Werkzeuggriffes aufweist, mindestens einer an dem Schaft vorgesehenen flexiblen Zunge, die eine nach außen abstehende Nase zum Eindringen in ein Loch des Werkzeuggriffes aufweist, und mit einem Betätigungselement zum Bewegen der Zunge zum Lösen des Verbinders von dem Werkzeuggriff.The invention relates to a tool handle for attachment to a tool handle, comprising a connector having a shaft for insertion into a channel of a tool handle, at least one provided on the shaft flexible tongue having an outwardly projecting nose for penetrating into a hole of the tool handle and an actuator for moving the tongue to release the connector from the tool handle.

Werkzeuge, wie beispielsweise Tapezierrollen, haben einen Werkzeuggriff, der hohl ist und in seiner Umfangswand zwei einander gegenüberliegende Löcher aufweist. Zur Verlängerung des Werkzeuges kann der Schaft eines Werkzeugstiels in einen Kanal des Werkzeuggriffes eingesetzt und verriegelt werden. Der Stiel ermöglicht dann den Einsatz des Werkzeuges an Stellen, an die der Benutzer ohne eine Verlängerung nicht heranreichen kann.Tools, such as wallpaper rolls, have a tool handle that is hollow and has two opposing holes in its peripheral wall. To extend the tool, the shaft of a Tool handle are inserted and locked in a channel of the tool handle. The handle then allows the tool to be used in places where the user can not reach without an extension.

Ein Werkzeugstiel, von dem der Oberbegriff des Anspruchs 1 ausgeht, ist beschrieben in WO 01/51257 A1 (Anza AB ). Der Verbinder hat einen längslaufenden Schaft mit einer ebenfalls längslaufenden flexiblen Zunge, die mit einer nach außen abstehenden Nase versehen ist. Die Nase ist dazu bestimmt, in das Loch eines Werkzeuggriffes einzudringen, wenn der Schaft in das Loch eingeschoben ist. Die Nase wird in dem Loch des Werkzeuggriffes verrastet und sperrt das Herausziehen des Verbinders aus dem Werkzeuggriff. Zum Lösen dieser Verriegelung ist an dem rückwärtigen Bereich der Zunge ein Knopf vorgesehen, der sich außerhalb des Werkzeughandgriffes befindet und eingedrückt werden kann, so dass er die flexible Zunge mit der daran befindlichen Nase niederdrückt. Dadurch gelangt die Nase außer Eingriff mit dem Loch des Werkzeuggriffs und der Verbinder kann aus diesem Loch herausgezogen werden.A tool handle, from which the preamble of claim 1 proceeds, is described in WO 01/51257 A1 (Anza AB ). The connector has a longitudinal shaft with a likewise longitudinally extending flexible tongue, which is provided with an outwardly projecting nose. The nose is designed to penetrate the hole of a tool handle when the shaft is inserted into the hole. The nose is locked in the hole of the tool handle and locks the extraction of the connector from the tool handle. To release this lock, a button is provided at the rear portion of the tongue, which is located outside the tool handle and can be pressed so that it depresses the flexible tongue with the nose thereon. As a result, the nose is disengaged from the hole of the tool handle and the connector can be pulled out of this hole.

Der Erfindung liegt die Aufgabe zugrunde, den Verbinder eines Werkzeugstieles im Hinblick auf die Sicherheit der Verriegelung und die Einfachheit der Entriegelung zu verbessern.The invention has for its object to improve the connector of a tool handle with regard to the safety of the lock and the simplicity of unlocking.

Der erfindungsgemäße Werkzeugstiel ist durch den Anspruch 1 definiert. Er ist dadurch gekennzeichnet, dass das Betätigungselement ein auf dem Schaft bewegbarer Schieber ist, der über mindestens eine Steuerfläche in Abhängigkeit von seiner Position die Zunge in den Schaft einzieht, derart, dass durch Bewegen des Schiebers auf dem Schaft der Werkzeuggriff von dem Verbinder lösbar ist.The tool handle according to the invention is defined by claim 1. It is characterized in that the actuating element is a slide movable on the shaft, which retracts the tongue into the shaft via at least one control surface depending on its position, such that by moving the slider on the shaft the tool handle is detachable from the connector ,

Dadurch, dass das Betätigungselement ein Schieber ist, der zum Zwecke der Entriegelung verschoben werden muss, ist die Sicherheit gegen unbeabsichtigte Entriegelung erhöht. Andererseits ist die Handhabung der Vorrichtung einfach, weil das Bewegen des Schiebers mit der den Verbinder haltenden Hand im Einhandbetrieb möglich ist, so dass die andere Hand frei bleibt. Das Verschieben des Schiebers erfolgt vorzugsweise als Linearverschiebung in Längsrichtung der Achse des Verbinders bzw. Schafts. Es ist aber auch möglich, den Schieber als Drehschieber auszubilden, der zum Zwecke des Entriegelns um die Achse gedreht wird. Der Schieber ist einer Federwirkung ausgesetzt, die ihn in die Verriegelungsposition treibt. Zum Entriegeln muss die Kraft der Feder manuell überwunden werden.Characterized in that the actuating element is a slide which must be moved for the purpose of unlocking, the security against unintentional unlocking is increased. On the other hand, the handling of the device is simple, because moving the slider with the hand holding the connector is possible in one-handed operation, so that the other hand remains free. The displacement of the slider is preferably carried out as a linear displacement in the longitudinal direction of the axis of the connector or shaft. But it is also possible to form the slide as a rotary valve, which is rotated for the purpose of unlocking about the axis. The slider is subjected to a spring action that drives it into the locking position. To unlock, the force of the spring must be overcome manually.

Eine erste Steuerfläche kann an der Zunge des Verbinders vorgesehen sein und/oder eine schräge zweite Steuerfläche an der Innenseite des Schiebers. Vorzugsweise sind zwei zusammenwirkende Steuerflächen vorgesehen, die kooperieren, um die Bewegung des Schiebers in eine Radialbewegung der Zunge in Bezug auf die Achse des Schafts umzusetzen. Die Verwendung der Steuerflächen bewirkt, dass die Feder, die die Zunge des Schafts in die Verriegelungsposition treibt, zugleich den Schieber in seine Ruheposition treibt, so dass eine separate Feder für diesen Zweck nicht erforderlich ist. Die Zunge bildet eine Blattfeder, die in Verbindung mit mindestens einer Steuerfläche den Schieber in Richtung des vorderen Schaftendes treibt.A first control surface may be provided on the tongue of the connector and / or an oblique second control surface on the inside of the slider. Preferably, two cooperating control surfaces are provided which cooperate to translate the movement of the slider into a radial movement of the tongue with respect to the axis of the shaft. The use of the control surfaces causes the spring, which drives the tongue of the shaft to the locking position, at the same time drives the slider in its rest position, so that a separate spring for this purpose is not required. The tongue forms a leaf spring which, in conjunction with at least one control surface, drives the slider in the direction of the front shaft end.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist an der Zunge ein Anschlagelement für den Schieber vorgesehen, wodurch die Bewegung des Schiebers begrenzt wird. Dadurch ist der Schieber unverlierbar an dem Schaft des Verbinders festgelegt. Zum Entfernen des Schiebers kann allerdings die Zunge eingedrückt werden, so dass der Schieber dann über das freie Ende des Schafts hinweg freikommt.According to a preferred embodiment of the invention, a stop element for the slider is provided on the tongue, whereby the movement of the slider is limited. As a result, the slider is captively fixed to the shaft of the connector. To remove the slider, however, the tongue can be pressed in, so that the slider is then released over the free end of the shaft away.

Gemäß einer bevorzugten Ausgestaltung der Erfindung sind an dem Schaft zwei Zungen vorgesehen, deren Nasen in unterschiedlichen Längspositionen angeordnet sind. Dadurch ist es möglich, den Werkzeugstiel bzw. den Verbinder zusammen mit unterschiedlichen Werkzeuggriffen zu verwenden, deren Löcher unterschiedlich positioniert sind.According to a preferred embodiment of the invention, two tongues are provided on the shaft, the lugs are arranged in different longitudinal positions. This makes it possible, the tool handle or the connector to use together with different tool handles whose holes are positioned differently.

Bei einer bevorzugten Ausführungsform der Erfindung ist der Schieber ein Schiebering, der den Umfang des Schafts vollständig umgibt.In a preferred embodiment of the invention, the slider is a sliding ring which completely surrounds the circumference of the shaft.

Die flexible Zunge kann einen längslaufenden Vorsprung aufweisen, der in eine Nut des Schiebers ragt und ein Drehen des Schiebers auf dem Schaft verhindert.The flexible tongue may have a longitudinal projection which projects into a groove of the slider and prevents rotation of the slider on the shaft.

Die Erfindung bietet eine hohe Sicherheit gegen unbeabsichtigtes Entriegeln der Verbindung. Es sind nur zwei Teile erforderlich, nämlich der Verbinder und der Schieber. Diese Teile können als Kunststoff-Formteile jeweils einstückig hergestellt werden. Ihr Zusammenbau ist sehr einfach. Die Rückstellkraft für den Schieber wird durch die flexible Zunge des Schafts aufgebracht.The invention provides a high level of security against unintentional unlocking of the connection. There are only two parts required, namely the connector and the slider. These parts can be made in one piece as plastic molded parts. Their assembly is very simple. The return force for the slider is applied by the flexible tongue of the shaft.

Im Folgenden wird ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnungen näher erläutert.In the following an embodiment of the invention will be explained in more detail with reference to the drawings.

In Figur 1 ist ein Werkzeug 10 dargestellt, mit einem Werkzeuggriff 11, der hohl ist und einen längslaufenden Kanal 12 aufweist. In der Umfangswand des Kanals 12 befinden sich zwei gegenüberliegende Löcher 13, die primär dazu dienen, das Werkzeug an einem Verkaufsständer oder einer sonstigen Halteeinrichtung aufhängen zu können.In FIG. 1 a tool 10 is shown with a tool handle 11 which is hollow and has a longitudinal channel 12. In the peripheral wall of the channel 12 are two opposing holes 13, which serve primarily to hang the tool on a display stand or other holding device can.

Der Werkzeugstiel 15 besteht aus einer Stange 16, beispielsweise aus einem Metallprofil oder aus Holz, mit einem am vorderen Ende befestigten Verbinder 17. Der Verbinder 17 besteht aus einem einstückigen Teil, das vorzugsweise aus Kunststoff besteht. Er hat an seinem rückwärtigen Ende eine zylindrische Manschette 18 zum Einstecken und Befestigen der Stange 16. Von der Manschette 18 steht nach vorne ein Schaft 19 ab, der vorzugsweise eine geringe Konizität hat und hohl ist. Das vordere Ende des Schafts 19 ist mit einer Stirnwand verschlossen.The tool handle 15 consists of a rod 16, for example of a metal profile or of wood, with a front end attached to the connector 17. The connector 17 consists of a one-piece part, which preferably consists of plastic. He has at its rear end a cylindrical sleeve 18 for insertion and fixing of the rod 16. From the collar 18 projects forward from a shaft 19, which preferably has a small conicity and is hollow. The front end of the shaft 19 is closed with an end wall.

In der Wand des Schaftes 19 befinden sich zwei diametral gegenüberliegende längslaufende Schlitze 20. In jedem Schlitz 20 erstrecken sich zwei Zungen 21, 22, die von der Manschette 18 ausgehen. Diese Zungen sind einstückig mit dem Schaft 19 bzw. der Manschette 18 verbunden und sie sind elastisch, so dass sie radial zur Achse des Schafts 19 federn können. Jede der Zungen 21, 22 hat ein mit der Manschette 18 verbundenes festes Ende und ein freies äußeres Ende 23.In the wall of the shaft 19 are two diametrically opposed longitudinal slots 20. In each slot 20, two tongues 21, 22 extending from the sleeve 18 extend. These tongues are integrally connected to the shaft 19 and the sleeve 18 and they are elastic so that they can spring radially to the axis of the shaft 19. Each of the tongues 21, 22 has a fixed end connected to the collar 18 and a free outer end 23.

In der Nähe des freien Endes 23 befindet sich an jeder Zunge 21, 22 eine nach außen abstehende Nase 24, 25. Die Nasen 24, 25 haben unterschiedliche Abstände von der Manschette 18 und dienen dazu, den Verbinder für unterschiedliche Werkzeuggriffe 11 verwendbar zu machen, bei denen die Löcher 13 sich an anderen Stellen befinden. Die Zungen 21, 22 federn unabhängig voneinander.Near the free end 23 is located on each tongue 21, 22 an outwardly projecting lug 24, 25. The lugs 24, 25 have different distances from the sleeve 18 and serve to make the connector for different tool handles 11 usable, where the holes 13 are in other places. The tongues 21, 22 spring independently of each other.

Jede Zunge 21, 22 hat ein Anschlagelement 26. Das Anschlagelement 26 ist sägezahnförmig und hat eine steile Hinterkante 27 und eine bogenförmige oder rampenförmige Vorderkante 28.Each tongue 21, 22 has a stop element 26. The stop element 26 is sawtooth-shaped and has a steep trailing edge 27 and an arcuate or ramp-shaped leading edge 28.

Hinter den Anschlagelementen 26 befinden sich auf dem Schaft 19 längslaufende Stege 30 mit einer am vorderen Ende vorgesehenen schrägen Steuerfläche 31, die zu der Hinterkante 27 hin abfällt und kurz hinter dem Anschlag endet.Behind the stop elements 26 are located on the shaft 19 longitudinal webs 30 with an opening provided at the front oblique control surface 31, which drops to the trailing edge 27 out and ends shortly behind the stop.

Figur 3 zeigt eine perspektivische Darstellung des auf den Schaft 19 sitzenden Schiebers 35. Dieser besteht aus einem generell zylindrischen Schiebering 36, der zwei diametral gegenüberliegende längslaufende Nuten 37 aufweist, an deren vorderes Ende sich eine schräge Steuerfläche 38 anschließt. Die Nuten 37 dienen als Führungen für die Stege 30 des Schafts und die erste Steuerfläche 31 des Schafts wirkt mit der zweiten Steuerfläche 38 des Schieberinges 36 zusammen, wobei ein axiales Rückziehen des Schieberinges 36 bewirkt, dass die Zungen 21, 22 heruntergedrückt werden. Gleichzeitig bewirken die federnden Zungen eine nach vorne gerichteten Kraft auf den Schiebering 36, der dadurch mit seinem vorderen Rand gegen die Anschlagelemente 26 gedrückt wird. FIG. 3 shows a perspective view of sitting on the shaft 19 slider 35. This consists of a generally cylindrical sliding ring 36 having two diametrically opposed longitudinal grooves 37, at the front end of which an inclined control surface 38 connects. The grooves 37 serve as guides for the webs 30 of the shaft and the first control surface 31 of the shaft cooperates with the second control surface 38 of the sliding ring 36, wherein an axial retraction of the sliding ring 36 causes the tongues 21, 22 are depressed. At the same time the resilient tongues cause a forwardly directed force on the sliding ring 36, which is thereby pressed with its front edge against the stop elements 26.

Figur 4 zeigt die Position des Schiebers 35 in der Ruhestellung. Die Vorderkante des Schiebers wird gegen die Hinterkante der Anschlagelemente 26 gedrückt und die Steuerflächen 31 und 38 liegen gleitend aufeinander. Die federnden Zungen 21 halten die Nasen 24 nach außen gedrückt, so dass die Nasen in den Löchern 13 des Werkzeuggriffes 11 einrasten. FIG. 4 shows the position of the slider 35 in the rest position. The leading edge of the slider is pressed against the trailing edge of the stop members 26 and the cam surfaces 31 and 38 are slidably engaged. The resilient tongues 21 keep the tabs 24 pressed outward, so that the lugs engage in the holes 13 of the tool handle 11.

Figur 5 zeigt die Vorrichtung in der Verriegelungsstellung, also bei an dem Verbinder befestigten Werkzeuggriff 11. Benutzt wird in diesem Fall die zurückliegende Nase 25, während die Zunge 21 die vordere Nase 24 trägt, eingedrückt wird. Die Anschlagelemente 26 begrenzen auch die Einschubbewegung des Schafts 19 in den Werkzeuggriff. FIG. 5 shows the device in the locking position, that is attached to the connector tool handle 11. In this case, the previous nose 25 is used, while the tongue 21 carries the front nose 24, is pressed. The stop members 26 also limit the insertion movement of the shaft 19 in the tool handle.

Zum Lösen des Werkzeuggriffes 11 von dem Schaft 19 wird gemäß Figur 6 der Schieber 35 zurückgezogen, wodurch die Zungen radial zum Schaft 19 eingedrückt werden und die Nasen außer Eingriff mit den Löchern 13 kommen. Der Werkzeuggriff 11 kann dann von dem Schaft 19 leicht axial nach vorne abgezogen werden. Wird der Schieber 35 losgelassen, so wird er durch die Federkraft der Zungen gegen die Anschlagelemente 26 gedrückt. Dadurch können die Zungen in ihre Außenposition zurückfedern.To release the tool handle 11 of the shaft 19 is according to FIG. 6 the slider 35 is retracted, whereby the tongues are pressed radially to the shaft 19 and the lugs disengage from the holes 13. The tool handle 11 can then be easily pulled off the shaft 19 axially forward. If the slider 35 is released, it is pressed by the spring force of the tongues against the stop elements 26. This allows the tongues to spring back to their outer position.

Die Vorrichtung besteht mit dem Schaft 19 und dem Schieber 35 aus lediglich zwei Teilen, die auf einfache Weise montiert werden können, indem der Schieber 35 auf den Schaft 19 aufgeschoben wird. Dabei überwindet er mit seiner Steuerfläche 38 die Anschlagelemente 26, die zurückweichen, um den Schieber in seine Position durchzulassen.The device consists with the shaft 19 and the slider 35 of only two parts, which can be mounted in a simple manner by the slider 35 is pushed onto the shaft 19. He overcomes with its control surface 38, the stop elements 26, which recede to pass the slider into position.
