Description

Die Erfindung bezieht sich auf eine Vorrichtung zur dauerhaften formschlüssigen und spielfreien Verbindung eines Haushaltsgerätes an einem Stiel. Insbesondere bezieht sich die Erfindung auf eine Stielverbindung zur Befestigung von Gartengeräten, beispielsweise in Form von Rechen, Grubbern, Hacken, Unkrautvemichtem usw.The invention relates to a device for permanent positive and play-free connection of a household appliance on a stick. In particular relates the invention on a stem connection for attaching garden tools, for example in the form of rakes, cultivators, hoes, weed killers, etc.

Vielfach werden als Geräte-Stiele-Verbindungen sogenannte Tülle-Geräte/Tülle-Stiele benutzt, bei denen in eine konische Einsatztülle des Geräts das entsprechend konisch gestaltete Stielende eingetrieben wird, das darin unter Reibungsschluß festliegt. Temperatur- und Feuchtigkeitsschwankungen führen jedoch häufig schon nach relativ kurzer Zeit zu einer Lockerung der Reibschlußverbindung. Aus diesem Grund werden, zumeist in Verbindung mit derartigen Reibschlußverbindungen, zusätzliche Fixierungselemente benutzt, die einen Formschluß bewirken können. So ist es üblich in entsprechend vorgesehene Löcher der Tülle Nägel in das Stielende einzuschlagen. Auch hier ist jedoch eine Lockerung nicht auszuschließen, wenn sich das Holz des Stielendes im Lauf der Zeit verändert.So-called spout devices / spout stems are often used as device-stem connections used, in which in a conical insert sleeve of the device the corresponding conical designed stem end is driven, which is fixed under frictional engagement. However, temperature and humidity fluctuations often lead to relative a short time to loosen the frictional connection. Because of this, mostly in connection with such frictional connections, additional Fixing elements used that can cause a positive connection. So it is common in punch the appropriate holes in the spout nails into the end of the stem. Also However, loosening cannot be ruled out here if the wood of the handle end changed over time.

Es sind andererseits Stielbefestigungskupplungen bekannt, die eine formschlüssige Verbindung von Gerätestiel und Gerät ermöglichen, wobei einem Stiel mehrere Geräte oder einem Gerät mehrere Stiele (zum Beispiel unterschiedlicher Länge) zugeordnet werden können.On the other hand, there are known handle attachment couplings that have a positive fit Allow device handle and device to be connected, with one handle having multiple devices or assigned several handles (for example, different lengths) to one device can be.

Bei einer bekannten Stielbefestigungsvorrichtung muß dabei eine Klemmschraube gelöst bzw. angezogen werden. Wenn das Anziehen der Schraube mit der erforderlichen Kraft erfolgt, kann hierbei eine dauerhafte formschlüssige Verbindung hergestellt werden. Es hat sich jedoch herausgestellt, daß häufig die Schrauben nicht genügend fest angezogen werden und sich lockern. In a known handle fastening device, a clamping screw must be loosened or be tightened. When tightening the screw with the required force takes place, a permanent positive connection can be established. It However, it has been found that the screws are often not tightened sufficiently become and loosen up.

Es ist weiter durch die DE 31 30 703 C2 eine Stielbefestigungskupplung bekannt, bei der eine selbsttätige formschlüssige Einrastung erfolgt, wenn ein das Gerät tragender Geräteeinsteckzapfen in ein Geräteeinsatzloch eingeführt wird, in dem eine über eine Blattfeder abgestützte Riegelfalle angeordnet ist. Ein Lösen der Kupplung kann hierbei durch Betätigung eines Auslöseknopfes bewirkt werden, über den die eingerastete Blattfeder ausgehoben werden kann.It is also known from DE 31 30 703 C2 a handle mounting coupling in which an automatic positive locking takes place when a person carrying the device Device insertion pin is inserted into a device insertion hole in which one over a Leaf spring-supported bolt latch is arranged. The clutch can be released here by actuating a release button, via which the locked Leaf spring can be lifted out.

Es hat sich jedoch in der Praxis herausgestellt, daß man vielfach bevorzugt, jedes Gerät mit einem Stiel zur Verfügung zu haben, um bei Bedarf nicht erst eine Kupplungsverbindung lösen bzw. herstellen zu müssen. Ausgehend von dieser Erkenntnis liegt der Erfindung die Aufgabe zugrunde, eine dauerhafte formschlüssige und spielfreie Stielbefestigungsvorrichtung zu schaffen, und daß ein Gerät einfach und sicher an einem Stiel festgelegt werden kann und dann ständig mit dem Stiel in Verbindung verbleibt.However, it has been found in practice that one prefers many devices available with a handle so that you don’t need one when needed Loosen or make coupling connection. Based on this knowledge is the object of the invention, a permanent positive and play-free To create handle attachment device and that a device easily and securely on one Stem can be set and then remains in constant contact with the stem.

Gelöst wird die gestellte Aufgabe durch die Gesamtheit der im Anspruch 1 angegebenen Merkmale. Der Erfindung liegt demgemäß die Erkenntnis zugrunde, daß die bekannte und seit langem bewährte Stielbefestigungskupplung mit relativ einfachen Maßnahmen derart abgewandelt werden kann, daß eine dauerhafte Stielverbindung geschaffen ist.The problem is solved by all of the specified in claim 1 Characteristics. The invention is accordingly based on the knowledge that the known and long-proven handle mounting coupling with relatively simple measures like this can be modified that a permanent stem connection is created.

Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Appropriate embodiments of the invention result from the subclaims.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. in der Zeichnung zeigen:

  • Fig. 1 zeigt einen Stiel mit einem Gartengerät vor dem Zusammenschluß,
  • Fig. 2 zeigt die in Figur 1 dargestellten Teile nach Herstellung der formschlüssigen Verbindung,

  • FIG. 2 shows the parts shown in FIG. 1 after the positive connection has been established,
  • Fig. 3 shows a partial section of the connecting device of the handle and device in the assembled state.

    • Die Erfindung bezieht sich auf eine Vorrichtung mit der dauerhaft eine formschlüssige spielfreie Verbindung zwischen einem Gerätestiel 10 und einem Gartengerät 12, beispielsweise einem Grubber, hergestellt werden kann. Der Stiel 10, der aus Holz oder einem Rohr bestehen kann, trägt am geräteseitigen Ende ein Anschlußstück 14, das das Stielende umgreift und an diesem festgelegt ist. Das Gartengerät 12 weist ein Anschlußstück, bestehend aus einer Muffe 16 und einem aus dieser vorstehenden Geräteeinsteckzapfen 18, auf. Das hülsenartige Anschlußstück 14 weist einen Kunststoffeinsatz 15 auf, der mit einem in der Stielachse angeordneten Geräteeinsatzloch 20 versehen ist.The invention relates to a device with a permanent positive play-free connection between a tool handle 10 and a garden tool 12, for example, a cultivator. The stem 10, which is made of wood or can consist of a tube carries at the end of the device a connector 14, which Grips end of the handle and is attached to this. The garden tool 12 has a Connector, consisting of a sleeve 16 and one of the above Device plug 18, on. The sleeve-like connector 14 has one Plastic insert 15 on that with a device insertion hole arranged in the stem axis 20 is provided.

    Das Geräteeinsatzloch 20 und der Geräteeinsteckzapfen 18 besitzen einen gleichen polygonalen, vorzugsweise rechteckigen, Querschnitt, so daß beim Einstecken eine drehfeste Verbindung zustandekommt. Am Einsatzstück 15 ist eine Blattfeder 22 mit ihrem vorderen Ende 24 fest verankert und diese steht mit ihrem hinteren Ende, das als Riegelfalle eine Abkröpfung 26 aufweist, in das Geräteeinsatzloch 20 ein und ist quer zur Stielachse vorgespannt.The device insertion hole 20 and the device insertion pin 18 have the same polygonal, preferably rectangular, cross-section, so that when inserted a non-rotatable connection is established. On the insert 15 is a leaf spring 22 with her front end 24 firmly anchored and this stands with its rear end that as Bolt latch has an offset 26, in the device insertion hole 20 and is transverse to Arm axis biased.

    Die Anschlußmuffe 16 des Geräts weist einen Hülsenfortsatz 28 auf, der im zusammengesteckten Zustand (Figur 2 und 3) das vordere Ende der Anschlußhülse 14 des Stiels umschließt. Der Grund dieser Hülse bildet eine axiale Anschlagfläche für die Stimfläche des Stiels bzw. der Anschlußhülse 14 und des Einsatzstückes 15. Der Geräteeinsteckzapfen 18 weist am Ende eine abgeschrägte Steuerfläche 30 und eine querdurchlaufende Verriegelungsausnehmung 40 auf.The connecting sleeve 16 of the device has a sleeve extension 28 which in assembled state (Figures 2 and 3) the front end of the connecting sleeve 14th of the stem. The base of this sleeve forms an axial stop surface for the End face of the stem or the connecting sleeve 14 and the insert piece 15. The Device insertion pin 18 has a chamfered control surface 30 and one at the end transverse locking recess 40.

    Beim Einschieben des Geräteeinsteckzapfens 18 in das Geräteeinsatzloch 20 der Stielanschlußhülse 14, bzw. des Einsatzstückes 15, hebt die vordere Steuerfläche 30 des Geräteeinsteckzapfens die Blattfeder 22 aus, bis die Abkröpfung 46 in die Verriegelungsausnehmung 40 einfallen kann. Dann besteht eine formschlüssige Verbindung zwischen der hinteren steilen Flanke der Abkröpfung 26 und dem Hinterrand des Gehäuseeinsatzlochs. Eine Formschlußverbindung in der Gegenrichtung wird durch die stimseitigen Anschlagflächen der Muffe und der Einsteckhülse 14 bzw. des Einsatzstückes 15 bewirkt. Dabei kann eine materialbedingte oder konstruktionsbedingte Federwirkung die Formschlußverbindung dauerhaft spielfrei aufrechterhalten. Das freie Ende der Feder 22 weist im Anschluß an die steile Flanke der Abkröpfung 26 einen achsparallelen Endabschnitt 27 auf, der im gesteckten Zustand federnd dem Endabschnitt des Geräteinsteckzapfens anliegt.When inserting the device insertion pin 18 in the device insertion hole 20 of the Handle connecting sleeve 14, or the insert 15, lifts the front control surface 30 of the Device insertion pin the leaf spring 22 until the elbow 46 in the Locking recess 40 can occur. Then there is a positive Connection between the rear steep flank of the bend 26 and the rear edge the housing insert hole. A positive connection in the opposite direction is made by the end faces of the sleeve and the insertion sleeve 14 or the Insert 15 causes. A material-related or construction-related Spring action maintain the positive connection permanently without play. The free The end of the spring 22 has one following the steep flank of the bent portion 26 axially parallel end portion 27, the end portion resilient in the inserted state of the device plug-in pin.

    Wie aus Figur 3 ersichtlich kann das Vorderende der Anschlußhülse 14 mit Federklauen 42 versehen sein, die auf den Geräteeinsteckzapfen einwirken und eine Abstützung am Muffboden bewirken.As can be seen from Figure 3, the front end of the connecting sleeve 14 with spring claws 42 be provided, which act on the device insertion pin and a support on Effect muff bottom.

    Normalerweise soll die einmal eingerastete Verbindung dauerhaft erhalten bleiben. Gemäß einer weiteren Ausgestaltung der Erfindung soll jedoch auch eine Möglichkeit geschaffen werden, das in das Stielende eingesteckte Gerät ohne Beschädigung der Verbindungsteile wieder zu lösen. Dies kann zweckmäßig sein, wenn eines der Teile beschädigt und der andere Teil noch voll funktionsfähig ist, beispielsweise beim Bruch des Stiels. Zu diesem Zweck ist in der Anschlußhülse 14 eine Bohrung 44 in Höhe der Abkröpfung 26 und dieser gegenüberliegend angeordnet. Durch diese Bohrung 44 kann in Radialrichtung ein Stift eingeführt werden, der die Blattfeder nach außen drückt und damit die Formschlußverriegelung aufhebt, und ein Herausziehen des Geräteeinsteckzapfens ermöglicht. Diese Bohrung kann abgedeckt und für den Benutzer verborgen sein, um nur den Händler in die Lage zu versetzen, den Austausch vorzunehmen.Normally, the connection, once snapped in, should be maintained permanently. According to a further embodiment of the invention, however, there should also be a possibility be created, the device inserted into the stem end without damaging the Loosen connecting parts again. This can be useful if one of the parts damaged and the other part is still fully functional, for example if the Stem. For this purpose, a bore 44 in the amount of the Elbow 26 and arranged opposite this. Through this bore 44 in Radial direction are inserted a pin that pushes the leaf spring outwards and thus releases the positive locking, and pulling out the device plug-in pin allows. This hole can be covered and hidden to the user only enable the dealer to carry out the exchange.
