- the invention relates to a tillage implement with a base implement, a front attachment connectable to the base implement and an interface for connecting the front attachment to the base implement.
- the invention also relates to a basic device of a soil cultivation device with an interface inner part, which is designed for connection to an interface outer part of a header device to be connected to the base device, and a header device for a soil cultivation device, the header device having an interface outer part, which for connection to an interface inner part of a base unit to be connected to the front unit.
- Soil cultivation devices with a basic device and an attachment device that can be connected to them are known in the prior art.
- the soil cultivation device can be, for example, a cleaning device, in particular a vacuum cleaner, act, the base unit of which has a power supply, a motor-blower unit and a dust chamber.
- the motor-blower unit is used to suck dust and dirt into the dust chamber.
- One or more attachments can be connected to the base unit.
- the attachment can have, for example, a rotating bristle element, a wiping element, a polishing device or the like.
- the interface of the soil tillage implement provides a suction channel connection, mechanical connection and electrical connection between the front attachment and the base unit.
- the interface has an interface outer part and an interface inner part, which can be plugged into one another in order to connect the attachment device to the base device.
- the patent specification EP 0 666 051 B1 discloses, for example, a suction line connector for a vacuum cleaner, with a suction line section as a plug-in part, a counterpart as a plug receiving part of an attachment and electrical contacts, which are arranged outside a cross section of the suction line section and the counterpart.
- the plug-in part and the plug-in part of the suction line connector have cross-sections which correspond to one another, so that the corresponding plug parts can be connected to one another, the two plug parts being aligned with one another via a flattening associated with the electrical contacts.
- an interface of the type described above in which the interface outer part and the interface inner part furthermore each have at least two shape coding element pairs, a first shape coding element pair of the interface outer part being designed in a position and shape corresponding to a first shape coding element pair of the interface inner part, and wherein a second shape coding element pair of the interface outer part is designed to correspond in position and shape to a second shape coding element pair of the interface inner part, each shape coding element pair each having two shape coding elements of identical shape and formed separately from one another.
- the interface is now designed with a shape coding in order to specifically achieve or exclude plug compatibility of the interface outer part and the interface inner part.
- This enables or prevents certain basic device / front device combinations.
- the manufacturer can selectively code valid combinations via the interface or code non-valid combinations.
- different codes for different ones can also be used Device generations may be provided.
- the coding can, for example, prevent low-voltage systems from being compatible with high-voltage systems.
- Certain basic devices and attachments that are not coordinated with one another for example, with regard to their working points, cannot therefore be combined. A combination of devices that are not coordinated with one another could otherwise lead to a malfunction and / or damage to one of the devices and is therefore excluded.
- the compatibility or incompatibility of the interface parts is prevented in detail by providing two pairs of shape coding elements on each of the interface parts, which, as shape coding elements, comprise, for example, defined projections and troughs in the respective interface part, which only correspond to correspondingly corresponding troughs or projections of the other interface part.
- the compatibility of the interface parts therefore not only requires that the shape of a suction channel end section and the contact carrier correspond to one another, but rather there must also be compatibility of the pairs of shape coding elements on both sides of the interface outer part and the interface inner part of the interface.
- the shape coding element pairs each have at least two shape coding elements, which are preferably of identical design with respect to their shape.
- the shape coding elements are furthermore particularly preferably arranged symmetrically with respect to an axis of symmetry of the interface, for example a longitudinal axis of the suction channel.
- the form coding element pairs primarily take on the function of form coding the interface, not other functions such as suction channel connection or electrical connection of the interface parts. These functions are primarily reserved for the suction channel or suction channel end section and the contact carrier.
- the first shape coding element pairs be in relation to their shape and their position on the Distinguish the interface from the second form coding element pairs. Because the interface has two different types of shape coding element pairs, which differ in terms of their shape and their position at the interface, different combinations of a main device with several attachments can be permitted or excluded. If at least one of the shape coding element pairs of the basic device matches a shape coding element pair of the front device and the respective second shape coding element pair does not prevent a connection, the respective base device and the front device can be connected to one another. In particular, this is advantageous for establishing compatibility or non-compatibility between different generations of devices. This will be explained in more detail later with reference to the description of the figures.
- a suction channel end section of the suction channel of the interface inner part be inserted into the interface outer part when the interface is connected, the axial overlap of the interface inner part and the interface outer part being at least 20 mm, preferably at least 25 mm.
- the interface inner part is inserted with the defined axial overlap into the interface outer part, the suction channel end section of the suction channel of the interface inner part serving as a stiffening tube and, alternatively, required complex interface parts, which have to be butted against one another, can be omitted.
- the pushing together of the interface inner part and the outer interface part further enables a rough alignment of the two interface parts to each other, whereby the alignment of the electrical contacts on both sides is facilitated.
- an axial overlap of the interface parts of at least 20 mm has proven useful, in particular in the case of suction channels which have an elliptical suction channel end section with a diameter ratio of D max / D min of approximately 20 mm to 14 mm.
- the contact carrier have more than three electrical contacts.
- the contact carrier preferably has three electrical contacts for a power supply of the front attachment through the base unit and at least one additional electrical contact for signal transmission between the base unit and the front attachment.
- the contact carrier and its electrical contacts are separated from the suction path of the suction channel. This results in a high level of electrical coupling security on the one hand, and optimal flow guidance within the suction channel on the other.
- the interface or the contact carrier has at least one further electrical contact. This can initially be designed as a reserve contact for an expandable electrical contacting of the interface, and / or preferably enable signal transmission between the base unit and the front unit.
- the electrical contacts can be provided one behind the other in the circumferential direction of the interface inner part.
- the contact carrier can be designed such that it has the shape of a ring section which at least partially surrounds the suction channel. This results in a greater approximation of the interface overall to a circular shape, so that ergonomic haptics are maintained for a user of the tillage device.
- the electrical contacts can be arranged as a plug-in part or receiving part on the interface inner part and the interface outer part, or vice versa.
- the electrical contacts are arranged such that they can be displaced on the interface inner part and / or the interface outer part, with a movement play of a pair of electrical contacts consisting of corresponding electrical contacts of the interface inner part and the interface outer part being in particular at least 1 mm.
- the electrical contacts are preferably floating on the contact carrier or the interface inner part or the interface outer part suspended. In contrast to a rigid suspension of the electrical contacts, contact damage can thus be avoided, which can occur due to a vibration of the interface with a constant wobble of, for example, approximately 1 mm.
- the proposed floating, ie displaceable, suspension of the electrical contacts keeps the movement of the interface away from the contact points of the electrical contacts.
- the contact carrier is arranged axially set back relative to a suction channel end section of the suction channel.
- the electrical contacts of the interface inner part or the interface outer part are removed from a suction channel end section of the suction channel, so that when the interface is joined, the profile in the area of the suction channel end sections initially interlocks and the electrical contacts are still kept free of coupling-related forces.
- an end face of the suction channel end section has an acute angle to a longitudinal axis of the suction channel end section.
- the suction channel end section of the suction channel is cut obliquely and can have an angle of, for example, 30 °. This also allows corner areas of an environment to be cleaned to be optimally cleaned.
- the interface inner part has a cross-sectional area that gradually increases in the axial direction of the suction channel, in particular individual circumferential tracks of a peripheral surface of the interface inner part compared to adjacent partial surface areas of the peripheral surface protrude radially outward, the peripheral tracks of the interface inner part abutting corresponding radial projections of the interface outer part protruding radially inward when the interface is closed and thereby spacing adjacent partial surface areas from one another.
- the interface section to be inserted into a receptacle of the counterpart increases in a step-like manner starting from a suction channel end section.
- the contact carrier is preferably assigned to a larger step of the interface inner part.
- special peripheral tracks are provided on the peripheral surface of the interface inner part, which define a step fit system. The actual contact between the interface inner part and the interface outer part then takes place with the interface closed, essentially via the defined circumferential paths, which form fitting rings of the system.
- the interface thus has a fitting profile between the interface parts.
- a suction channel end section of the suction channel of the interface inner part has an abrasion-resistant soft material.
- the interface inner part is therefore preferably equipped with an advantageous direct suction option, so that the interface inner part can be brought up directly to the surface without damaging the interface inner part or a surface to be cleaned.
- the suction channel end section of the suction channel of the interface inner part preferably has a wear zone made of an abrasion-resistant soft material which has material properties such as having optimal abrasion resistance, prevention of staining and mechanical strength.
- the abrasion-resistant soft material can be a synthetic rubber material.
- the soft material is preferably arranged detachably on the suction channel. The user can thus remove the abrasion-resistant soft material as desired from the suction channel end section, for example if he wants to close the interface. Alternatively, the interface can also be closed when soft material is present.
- the interface inner part in particular the contact carrier, has an actuating element which can be latched into a shape-corresponding opening of the interface outer part, the actuating element having a latching element which can be latched into a recess in the interface outer part.
- the latching element and / or a border of the recess can have an inclined contact surface in the joining direction and / or opposite to the joining direction for the sliding overcoming of the border by the latching element.
- the actuating element creates a latching connection between the interface parts of the interface, the inner interface part and the outer interface part being coupled to one another.
- the actuating element can be designed in such a way that the latching element is moved away from a corresponding latching element of the outer interface part in the event of bending stress or displacement of the actuating element, so that the latching connection can be released.
- the bending stress, or for example also a pivoting, of the actuating element can preferably result in a contact surface of the latching element being able to overcome the border of the recess.
- the inclined contact surface of the latching element and / or the border of the recess which is proposed in particular, ensures that the latching can also be carried out and / or released when the actuating element is not actuated. In particular, this can achieved that the interface outer part can be removed from the interface inner part without actuating the actuating element.
- an outwardly facing peripheral surface of the interface inner part has a circumferential groove in which a shape-corresponding sealing element is arranged.
- the shape-corresponding sealing element ensures that the interface is sealed, regardless of the quality of the fit between the outer interface part and the inner interface part.
- the sealing element is preferably made of an elastic material, so that a play between the interface parts can be compensated.
- the groove provided for the sealing element is preferably aligned with a step of the previously proposed step profile of the cross-sectional area of the interface inner part, so that the sealing element acts immediately at the beginning of the interface coupling.
- an outwardly facing peripheral surface of the interface inner part has lamellae oriented in the circumferential direction for non-positive contact with an inwardly facing peripheral surface of the interface outer part.
- the interface inner part can alternatively or in addition to the use of an actuating element by means of the lamellae be frictionally connected to the interface outer part.
- the lamellae are preferably essentially transverse to the longitudinal extent of the suction channel.
- a suction channel end section of the interface inner part can also be surrounded by a lamella in a helical shape.
- the lamellae are preferably made of a hard elastic material, so that on the one hand they provide the required adhesion to the inner surface of the interface outer part can provide, and on the other hand have a certain flexibility so that the interface inner part can be pushed into the interface outer part.
- the invention also proposes a tillage implement with a base unit, a front attachment that can be connected to the base unit, and an interface for connecting the front attachment to the base unit, the interface being designed according to one of the previously described embodiments, and wherein the The interface outer part is assigned in particular to the front attachment and the interface inner part is assigned to the base device.

Description
Die Erfindung betrifft eine Schnittstelle für ein Bodenbearbeitungsgerät mit einem Basisgerät und einem mit dem Basisgerät verbindbaren Vorsatzgerät, wobei die Schnittstelle ein Schnittstellenaußenteil und ein formkorrespondierend zu dem Schnittstellenaußenteil ausgebildetes Schnittstelleninnenteil aufweist, wobei das Schnittstelleninnenteil einen Saugkanal und einen außerhalb des Saugkanals angeordneten Kontaktträger mit einer Mehrzahl von Elektrokontakten aufweist und wobei das Schnittstellenaußenteil eine Mehrzahl von korrespondierenden Elektrokontakten aufweist.The invention relates to an interface for a soil cultivation device with a base device and a front device that can be connected to the base device, the interface having an interface outer part and an interface inner part designed to correspond to the interface outer part, the interface inner part having a suction channel and a contact carrier arranged outside the suction channel with a plurality of Has electrical contacts and the interface outer part has a plurality of corresponding electrical contacts.

Darüber hinaus betrifft die Erfindung ebenso ein Basisgerät eines Bodenbearbeitungsgerätes mit einem Schnittstelleninnenteil, welches zur Verbindung mit einem Schnittstellenaußenteil eines mit dem Basisgerät zu verbindenden Vorsatzgerätes ausgebildet ist, sowie ein Vorsatzgerät für ein Bodenbearbeitungsgerät, wobei das Vorsatzgerät ein Schnittstellenaußenteil aufweist, welches zur Verbindung mit einem Schnittstelleninnenteil eines mit dem Vorsatzgerät zu verbindenden Basisgerätes ausgebildet ist.In addition, the invention also relates to a basic device of a soil cultivation device with an interface inner part, which is designed for connection to an interface outer part of a header device to be connected to the base device, and a header device for a soil cultivation device, the header device having an interface outer part, which for connection to an interface inner part of a base unit to be connected to the front unit.
Bodenbearbeitungsgeräte mit einem Basisgerät und einem damit verbindbaren Vorsatzgerät sind im Stand der Technik bekannt. Bei dem Bodenbearbeitungsgerät kann es sich beispielsweise um ein Reinigungsgerät, insbesondere einen Staubsauger, handeln, dessen Basisgerät eine Energieversorgung, eine Motor-Gebläse-Einheit und eine Staubkammer aufweist. Die Motor-Gebläse-Einheit dient zum Einsaugen von Staub und Schmutz in die Staubkammer. Mit dem Basisgerät können ein oder mehrere Vorsatzgeräte verbunden werden.Soil cultivation devices with a basic device and an attachment device that can be connected to them are known in the prior art. The soil cultivation device can be, for example, a cleaning device, in particular a vacuum cleaner, act, the base unit of which has a power supply, a motor-blower unit and a dust chamber. The motor-blower unit is used to suck dust and dirt into the dust chamber. One or more attachments can be connected to the base unit.
Das Vorsatzgerät kann beispielsweise ein rotierendes Borstenelement, ein Wischelement, eine Poliereinrichtung oder ähnliches aufweisen.The attachment can have, for example, a rotating bristle element, a wiping element, a polishing device or the like.
Die Schnittstelle des Bodenbearbeitungsgerätes stellt eine Saugkanalverbindung, mechanische Verbindung und elektrische Verbindung zwischen dem Vorsatzgerät und dem Basisgerät zur Verfügung.

The interface has an interface outer part and an interface inner part, which can be plugged into one another in order to connect the attachment device to the base device.
Die Patentschrift
Ausgehend von dem vorgenannten Stand der Technik kann es gewünscht sein, bestimmte Kombinationen von Basisgerät und Vorsatzgerät auszuschließen, beispielsweise um zu verhindern, dass ein Niederspannungsgerät an ein Hochspannungsgerät angeschlossen wird.On the basis of the aforementioned prior art, it may be desirable to exclude certain combinations of base unit and front unit, for example to prevent a low-voltage device from being connected to a high-voltage device.
Es ist somit Aufgabe der Erfindung, Bodenbearbeitungsgeräte mit einem Basisgerät und einem Vorsatzgerät bzw. ein Basisgerät, ein Vorsatzgerät und eine Schnittstelle entsprechend weiterzubilden.It is therefore an object of the invention to further develop soil cultivation devices with a basic device and a front attachment or a basic device, a front attachment and an interface.
Zur Lösung dieser Aufgabe wird zunächst eine Schnittstelle der zuvor beschriebenen Art vorgeschlagen, bei welcher das Schnittstellenaußenteil und das Schnittstelleninnenteil des Weiteren jeweils mindestens zwei Formkodierungselementepaare aufweisen, wobei ein erstes Formkodierungselementepaar des Schnittstellenaußenteils positions- und formkorrespondierend zu einem ersten Formkodierungselementepaar des Schnittstelleninnenteils ausgebildet ist, und wobei ein zweites Formkodierungselementepaar des Schnittstellenaußenteils positions- und formkorrespondierend zu einem zweiten Formkodierungselementepaar des Schnittstelleninnenteils ausgebildet ist, wobei jedes Formkodierungselementepaar jeweils zwei formgleiche und separat zueinander ausgebildete Formkodierungselemente aufweist.To solve this problem, an interface of the type described above is first proposed, in which the interface outer part and the interface inner part furthermore each have at least two shape coding element pairs, a first shape coding element pair of the interface outer part being designed in a position and shape corresponding to a first shape coding element pair of the interface inner part, and wherein a second shape coding element pair of the interface outer part is designed to correspond in position and shape to a second shape coding element pair of the interface inner part, each shape coding element pair each having two shape coding elements of identical shape and formed separately from one another.
Erfindungsgemäß ist die Schnittstelle nun mit einer Formkodierung ausgebildet, um gezielt eine Steckkompatibilität des Schnittstellenaußenteils und des Schnittstelleninnenteils zu erreichen bzw. auszuschließen. Dadurch können bestimmte Basisgerät-Vorsatzgerät-Kombinationen ermöglicht bzw. verhindert werden. Es können durch den Hersteller gezielt valide Kombinationen über die Schnittstelle kodiert werden bzw. nicht valide Kombinationen kodiert werden. Insbesondere können auch verschiedene Kodierungen für unterschiedliche Gerätegenerationen vorgesehen sein. Die Kodierung kann dabei, wie zuvor erwähnt, beispielsweise verhindern, dass Niederspannungssysteme zu Hochspannungssystemen kompatibel sind. Bestimmte Basisgeräte und Vorsatzgeräte, die beispielsweise bezüglich ihrer Arbeitspunkte nicht aufeinander abgestimmt sind, können somit nicht kombiniert werden. Eine Kombination von Geräten, die nicht aufeinander abgestimmt sind, könnte andernfalls zu einer Fehlfunktion und/oder zu einer Beschädigung eines der Geräte führen und wird somit ausgeschlossen. Die Kompatibilität bzw. Nicht-Kompatibilität der Schnittstellenteile wird im Einzelnen dadurch verhindert, dass an jedem der Schnittstellenteile jeweils zwei Formkodierungselementepaare vorgesehen sind, die als Formkodierungselemente beispielsweise definierte Vorsprünge und Mulden in dem jeweiligen Schnittstellenteil umfassen, die nur zu entsprechend formkorrespondierenden Mulden bzw. Vorsprüngen des anderen Schnittstellenteils passen. Die Kompatibilität der Schnittstellenteile erfordert somit nicht nur, dass die Form eines Saugkanalendabschnittes und des Kontaktträgers zueinander korrespondieren, sondern es muss vielmehr auch eine Kompatibilität der beiderseitigen Formkodierungselementepaare an dem Schnittstellenaußenteil und dem Schnittstelleninnenteil der Schnittstelle gegeben sein. Die Formkodierungselementepaare weisen jeweils mindestens zwei Formkodierungselemente auf, die vorzugsweise in Bezug auf deren Form gleichartig ausgebildet sind. Besonders bevorzugt sind die Formkodierungselemente des Weiteren bezogen auf eine Symmetrieachse der Schnittstelle, beispielsweise eine Längsachse des Saugkanals, symmetrisch angeordnet. Die Formkodierungselementepaare übernehmen vorrangig die Funktion der Formkodierung der Schnittstelle, nicht weitere Funktionen wie Saugkanalverbindung oder elektrische Verbindung der Schnittstellenteile. Diese Funktionen sind in erster Linie dem Saugkanal bzw. Saugkanalendabschnitt und dem Kontaktträger vorbehalten.According to the invention, the interface is now designed with a shape coding in order to specifically achieve or exclude plug compatibility of the interface outer part and the interface inner part. This enables or prevents certain basic device / front device combinations. The manufacturer can selectively code valid combinations via the interface or code non-valid combinations. In particular, different codes for different ones can also be used Device generations may be provided. As previously mentioned, the coding can, for example, prevent low-voltage systems from being compatible with high-voltage systems. Certain basic devices and attachments that are not coordinated with one another, for example, with regard to their working points, cannot therefore be combined. A combination of devices that are not coordinated with one another could otherwise lead to a malfunction and / or damage to one of the devices and is therefore excluded. The compatibility or incompatibility of the interface parts is prevented in detail by providing two pairs of shape coding elements on each of the interface parts, which, as shape coding elements, comprise, for example, defined projections and troughs in the respective interface part, which only correspond to correspondingly corresponding troughs or projections of the other interface part. The compatibility of the interface parts therefore not only requires that the shape of a suction channel end section and the contact carrier correspond to one another, but rather there must also be compatibility of the pairs of shape coding elements on both sides of the interface outer part and the interface inner part of the interface. The shape coding element pairs each have at least two shape coding elements, which are preferably of identical design with respect to their shape. The shape coding elements are furthermore particularly preferably arranged symmetrically with respect to an axis of symmetry of the interface, for example a longitudinal axis of the suction channel. The form coding element pairs primarily take on the function of form coding the interface, not other functions such as suction channel connection or electrical connection of the interface parts. These functions are primarily reserved for the suction channel or suction channel end section and the contact carrier.
Des Weiteren wird vorgeschlagen, dass sich die ersten Formkodierungselementepaare in Bezug auf deren Form und deren Position an der Schnittstelle von den zweiten Formkodierungselementepaaren unterscheiden. Dadurch, dass die Schnittstelle zwei verschiedene Arten von Formkodierungselementepaaren aufweist, die sich in Bezug auf deren Form und deren Position an der Schnittstelle unterscheiden, können unterschiedliche Kombinationen eines Hauptgerätes mit mehreren Vorsatzgeräten zugelassen bzw. ausgeschlossen werden. Sofern zumindest eines der Formkodierungselementepaare des Basisgerätes zu einem Formkodierungselementepaar des Vorsatzgerätes passt und das jeweils zweite Formkodierungselementepaar eine Verbindung nicht verhindert, können das jeweilige Basisgerät und das Vorsatzgerät miteinander verbunden werden. Insbesondere ist dies zur Ausbildung einer Kompatibilität bzw. Nicht-Kompatibilität zwischen unterschiedlichen Gerätegenerationen vorteilhaft. Hierzu wird später noch in Bezug auf die Figurenbeschreibung näher ausgeführt.Furthermore, it is proposed that the first shape coding element pairs be in relation to their shape and their position on the Distinguish the interface from the second form coding element pairs. Because the interface has two different types of shape coding element pairs, which differ in terms of their shape and their position at the interface, different combinations of a main device with several attachments can be permitted or excluded. If at least one of the shape coding element pairs of the basic device matches a shape coding element pair of the front device and the respective second shape coding element pair does not prevent a connection, the respective base device and the front device can be connected to one another. In particular, this is advantageous for establishing compatibility or non-compatibility between different generations of devices. This will be explained in more detail later with reference to the description of the figures.
Des Weiteren wird vorgeschlagen, dass ein Saugkanalendabschnitt des Saugkanals des Schnittstelleninnenteils bei verbundener Schnittstelle in das Schnittstellenaußenteil eingeführt ist, wobei die axiale Überlappung von Schnittstelleninnenteil und Schnittstellenaußenteil mindestens 20 mm, vorzugsweise mindestens 25 mm, beträgt. Der Schnittstelleninnenteil wird mit der definierten axialen Überlappung in das Schnittstellenaußenteil eingeführt, wobei der Saugkanalendabschnitt des Saugkanals des Schnittstelleninnenteils als Versteifungsrohr dient und alternativ benötigte aufwendige Schnittstellenteile, die auf Stoß aneinandergelegt werden müssen, entfallen können. Das Ineinanderschieben von Schnittstelleninnenteil und Schnittstellenaußenteil ermöglicht des Weiteren eine grobe Ausrichtung der beiden Schnittstellenteile zueinander, wodurch die Ausrichtung der beiderseitigen Elektrokontakte zueinander erleichtert ist. In der Praxis hat sich eine axiale Überlappung der Schnittstellenteile von mindestens 20 mm bewährt, insbesondere bei Saugkanälen, die einen elliptischen Saugkanalendabschnitt mit einem Durchmesserverhältnis von Dmax/Dmin von ungefähr 20 mm zu 14 mm aufweisen.Furthermore, it is proposed that a suction channel end section of the suction channel of the interface inner part be inserted into the interface outer part when the interface is connected, the axial overlap of the interface inner part and the interface outer part being at least 20 mm, preferably at least 25 mm. The interface inner part is inserted with the defined axial overlap into the interface outer part, the suction channel end section of the suction channel of the interface inner part serving as a stiffening tube and, alternatively, required complex interface parts, which have to be butted against one another, can be omitted. The pushing together of the interface inner part and the outer interface part further enables a rough alignment of the two interface parts to each other, whereby the alignment of the electrical contacts on both sides is facilitated. In practice, an axial overlap of the interface parts of at least 20 mm has proven useful, in particular in the case of suction channels which have an elliptical suction channel end section with a diameter ratio of D max / D min of approximately 20 mm to 14 mm.
Des Weiteren wird vorgeschlagen, dass der Kontaktträger mehr als drei Elektrokontakte aufweist. Vorzugsweise weist der Kontaktträger drei Elektrokontakte für eine Stromversorgung des Vorsatzgerätes durch das Basisgerät und mindestens einen zusätzlichen Elektrokontakt für eine Signalübertragung zwischen dem Basisgerät und dem Vorsatzgerät auf. Der Kontaktträger und dessen Elektrokontakte sind von dem Saugweg des Saugkanals getrennt. Somit ergeben sich einerseits eine hohe elektrische Kopplungssicherheit und andererseits eine optimale Strömungsführung innerhalb des Saugkanals. Neben den drei Elektrokontakten für die Stromversorgung des Vorsatzgerätes weist die Schnittstelle bzw. der Kontaktträger zumindest einen weiteren Elektrokontakt auf. Dieser kann zunächst als Reservekontakt für eine erweiterungsfähige Elektrokontaktierung der Schnittstelle ausgebildet sein, und/oder vorzugsweise eine Signalübertragung zwischen dem Basisgerät und dem Vorsatzgerät ermöglichen. Die Elektrokontakte können in Umfangsrichtung des Schnittstelleninnenteils hintereinander vorgesehen sein. Dadurch kann der Kontaktträger so ausgebildet sein, dass dieser die Form eines Ringabschnittes, welcher den Saugkanal zumindest teilweise umgibt, aufweist. Dadurch ergibt sich eine größere Annäherung der Schnittstelle insgesamt zu einer Kreisform, so dass eine ergonomische Haptik für einen Nutzer des Bodenbearbeitungsgerätes gewahrt bleibt. Die Elektrokontakte können als Einsteckteil bzw. Aufnahmeteil an dem Schnittstelleninnenteil und dem Schnittstellenaußenteil, bzw. umgekehrt, angeordnet sein.Furthermore, it is proposed that the contact carrier have more than three electrical contacts. The contact carrier preferably has three electrical contacts for a power supply of the front attachment through the base unit and at least one additional electrical contact for signal transmission between the base unit and the front attachment. The contact carrier and its electrical contacts are separated from the suction path of the suction channel. This results in a high level of electrical coupling security on the one hand, and optimal flow guidance within the suction channel on the other. In addition to the three electrical contacts for the power supply of the front attachment, the interface or the contact carrier has at least one further electrical contact. This can initially be designed as a reserve contact for an expandable electrical contacting of the interface, and / or preferably enable signal transmission between the base unit and the front unit. The electrical contacts can be provided one behind the other in the circumferential direction of the interface inner part. As a result, the contact carrier can be designed such that it has the shape of a ring section which at least partially surrounds the suction channel. This results in a greater approximation of the interface overall to a circular shape, so that ergonomic haptics are maintained for a user of the tillage device. The electrical contacts can be arranged as a plug-in part or receiving part on the interface inner part and the interface outer part, or vice versa.
Des Weiteren wird vorgeschlagen, dass die Elektrokontakte verlagerbar an dem Schnittstelleninnenteil und/oder dem Schnittstellenaußenteil angeordnet sind, wobei ein Bewegungsspiel eines Elektrokontaktpaares aus korrespondierenden Elektrokontakten des Schnittstelleninnenteils und des Schnittstellenaußenteils insbesondere mindestens 1 mm beträgt. Gemäß dieser Ausführung sind die Elektrokontakte vorzugsweise schwimmend beweglich an dem Kontaktträger bzw. dem Schnittstelleninnenteil oder dem Schnittstellenaußenteil aufgehängt. Im Gegensatz zu einer starren Aufhängung der Elektrokontakte kann somit eine Kontaktschädigung vermieden werden, die durch eine Erschütterung der Schnittstelle mit einem Dauerwackelspiel von beispielsweise ca. 1 mm auftreten kann. Die vorgeschlagene schwimmende, d. h. verlagerbare, Aufhängung der Elektrokontakte hält die Bewegung der Schnittstelle von den Kontaktierungsstellen der Elektrokontakte fern.Furthermore, it is proposed that the electrical contacts are arranged such that they can be displaced on the interface inner part and / or the interface outer part, with a movement play of a pair of electrical contacts consisting of corresponding electrical contacts of the interface inner part and the interface outer part being in particular at least 1 mm. According to this embodiment, the electrical contacts are preferably floating on the contact carrier or the interface inner part or the interface outer part suspended. In contrast to a rigid suspension of the electrical contacts, contact damage can thus be avoided, which can occur due to a vibration of the interface with a constant wobble of, for example, approximately 1 mm. The proposed floating, ie displaceable, suspension of the electrical contacts keeps the movement of the interface away from the contact points of the electrical contacts.
Es kann des Weiteren vorgesehen sein, dass der Kontaktträger relativ zu einem Saugkanalendabschnitt des Saugkanals axial zurückversetzt angeordnet ist. Gemäß dieser Ausgestaltung sind die Elektrokontakte des Schnittstelleninnenteils bzw. des Schnittstellenaußenteils von einem Saugkanalendabschnitt des Saugkanals entfernt, so dass beim Fügen der Schnittstelle zunächst das Profil im Bereich der Saugkanalendabschnitte ineinandergreift und die Elektrokontakte dabei noch von kupplungsbezogenen Kräften freigehalten werden.It can further be provided that the contact carrier is arranged axially set back relative to a suction channel end section of the suction channel. According to this embodiment, the electrical contacts of the interface inner part or the interface outer part are removed from a suction channel end section of the suction channel, so that when the interface is joined, the profile in the area of the suction channel end sections initially interlocks and the electrical contacts are still kept free of coupling-related forces.
Um einen Saugkanalendabschnitt des Schnittstelleninnenteils auch in Alleinstellung als Saugdüse verwenden zu können, d. h. ohne Anschluss eines Schnittstellenaußenteils, wird vorgeschlagen, dass eine Stirnfläche des Saugkanalendabschnittes zu einer Längsachse des Saugkanalendabschnittes einen spitzen Winkel aufweist. Mit anderen Worten: Der Saugkanalendabschnitt des Saugkanals ist schräg angeschnitten und kann einen Winkel von beispielsweise 30° aufweisen. Dadurch lassen sich auch Eckbereiche einer zu reinigenden Umgebung optimal reinigen.In order to be able to use a suction channel end section of the interface inner part on its own as a suction nozzle, d. H. Without connecting an outer interface part, it is proposed that an end face of the suction channel end section has an acute angle to a longitudinal axis of the suction channel end section. In other words: the suction channel end section of the suction channel is cut obliquely and can have an angle of, for example, 30 °. This also allows corner areas of an environment to be cleaned to be optimally cleaned.
Des Weiteren kann vorgesehen sein, dass das Schnittstelleninnenteil ausgehend von einem Saugkanalendabschnitt eine sich in axiale Richtung des Saugkanals stufenweise vergrößernde Querschnittsfläche aufweist, wobei insbesondere einzelne Umfangsbahnen einer Umfangsfläche des Schnittstelleninnenteils verglichen mit benachbarten Flächenteilbereichen der Umfangsfläche nach radial außen hervorstehen, wobei die Umfangsbahnen des Schnittstelleninnenteils bei geschlossener Schnittstelle gegen korrespondierende nach radial innen vorstehende Umfangsbahnen des Schnittstellenaußenteils stoßen und dadurch benachbarte Flächenteilbereiche voneinander beabstanden. Gemäß der erstgenannten Ausführung vergrößert sich der in eine Aufnahme des Gegenstücks einzuführende Schnittstellenabschnitt ausgehend von einem Saugkanalendabschnitt stufenförmig. Dadurch ergibt sich eine vorteilhafte und leichtgängig überwindbare Vorzentrierung der zu kuppelnden Schnittstellenteile, wobei erst bei Überfahren einer ersten Stufe die winkelmäßige Ausrichtung von Schnittstellenaußenteil und Schnittstelleninnenteil auftritt. Der Nutzer spürt eine satte, gut abdichtende Führung bis hinein in eine Endposition, die eine geschlossene Schnittstelle kennzeichnet. Der Kontaktträger ist vorzugsweise einer größeren Stufe des Schnittstelleninnenteils zugeordnet. Insbesondere sind gemäß der weiterhin vorgeschlagenen Ausführung besondere Umfangsbahnen an der Umfangsfläche des Schnittstelleninnenteils vorgesehen, welche ein Stufenpassungssystem definieren. Die eigentliche Berührung zwischen dem Schnittstelleninnenteil und dem Schnittstellenaußenteil findet bei geschlossener Schnittstelle dann im Wesentlichen über die definierten Umfangsbahnen statt, welche Passringe des Systems bilden. Die Schnittstelle verfügt somit zusätzlich zu dem gestuften Verlauf des Schnittstellenaußenteils und des Schnittstelleninnenteils über ein Passprofil zwischen den Schnittstellenteilen.Furthermore, it can be provided that, starting from a suction channel end section, the interface inner part has a cross-sectional area that gradually increases in the axial direction of the suction channel, in particular individual circumferential tracks of a peripheral surface of the interface inner part compared to adjacent partial surface areas of the peripheral surface protrude radially outward, the peripheral tracks of the interface inner part abutting corresponding radial projections of the interface outer part protruding radially inward when the interface is closed and thereby spacing adjacent partial surface areas from one another. According to the first-mentioned embodiment, the interface section to be inserted into a receptacle of the counterpart increases in a step-like manner starting from a suction channel end section. This results in an advantageous and easily overcome pre-centering of the interface parts to be coupled, the angular alignment of the outer interface part and the inner interface part only occurring when a first step is passed. The user feels a full, well-sealed guide right into an end position that characterizes a closed interface. The contact carrier is preferably assigned to a larger step of the interface inner part. In particular, according to the further proposed embodiment, special peripheral tracks are provided on the peripheral surface of the interface inner part, which define a step fit system. The actual contact between the interface inner part and the interface outer part then takes place with the interface closed, essentially via the defined circumferential paths, which form fitting rings of the system. In addition to the stepped course of the interface outer part and the interface inner part, the interface thus has a fitting profile between the interface parts.
Es kann vorgesehen sein, dass ein Saugkanalendabschnitt des Saugkanals des Schnittstelleninnenteils ein abriebfestes Weichmaterial aufweist. Das Schnittstelleninnenteil ist somit vorzugsweise mit einer vorteilhaften Direktsaugmöglichkeit ausgestattet, so dass das Schnittstelleninnenteil ohne Beschädigung des Schnittstelleninnenteils bzw. einer zu reinigenden Fläche unmittelbar an der Fläche herangeführt werden kann. Der Saugkanalendabschnitt des Saugkanals des Schnittstelleninnenteils verfügt vorzugsweise über eine Verschleißzone aus einem abriebfesten Weichmaterial, welches Werkstoffeigenschaften wie optimale Abriebfestigkeit, Abfärbeverhinderung und mechanische Festigkeit aufweist. Beispielsweise kann es sich bei dem abriebfesten Weichmaterial um ein synthetisches Kautschukmaterial handeln. Vorzugsweise ist das Weichmaterial abnehmbar an dem Saugkanal angeordnet. Somit kann der Nutzer das abriebfeste Weichmaterial nach Wunsch von dem Saugkanalendabschnitt entfernen, beispielsweise wenn er die Schnittstelle schließen möchte. Alternativ kann die Schnittstelle jedoch auch bei vorhandenem Weichmaterial geschlossen werden.It can be provided that a suction channel end section of the suction channel of the interface inner part has an abrasion-resistant soft material. The interface inner part is therefore preferably equipped with an advantageous direct suction option, so that the interface inner part can be brought up directly to the surface without damaging the interface inner part or a surface to be cleaned. The suction channel end section of the suction channel of the interface inner part preferably has a wear zone made of an abrasion-resistant soft material which has material properties such as having optimal abrasion resistance, prevention of staining and mechanical strength. For example, the abrasion-resistant soft material can be a synthetic rubber material. The soft material is preferably arranged detachably on the suction channel. The user can thus remove the abrasion-resistant soft material as desired from the suction channel end section, for example if he wants to close the interface. Alternatively, the interface can also be closed when soft material is present.
Es kann vorgesehen sein, dass das Schnittstelleninnenteil, insbesondere der Kontaktträger, ein Betätigungselement aufweist, welches in eine formkorrespondierende Öffnung des Schnittstellenaußenteils einrastbar ist, wobei das Betätigungselement ein Rastelement aufweist, welches in eine Aussparung des Schnittstellenaußenteils einrastbar ist. Des Weiteren kann das Rastelement und/oder eine Umrandung der Aussparung eine in Fügerichtung und/oder entgegen der Fügerichtung stehende schräge Kontaktfläche zum gleitenden Überwinden der Umrandung durch das Rastelement aufweisen. Durch das Betätigungselement ist eine Rastverbindung zwischen den Schnittstellenteilen der Schnittstelle geschaffen, wobei das Schnittstelleninnenteil und das Schnittstellenaußenteil aneinander gekuppelt werden. Beispielsweise kann das Betätigungselement so ausgestaltet sein, dass das Rastelement bei Biegebeanspruchung oder Verlagerung des Betätigungselementes von einem korrespondierenden Rastelement des Schnittstellenaußenteils wegbewegt wird, so dass die Rastverbindung gelöst werden kann. Vorzugsweise kann die Biegebeanspruchung, oder beispielsweise auch eine Verschwenkung, des Betätigungselementes dazu führen, dass eine Kontaktfläche des Rastelementes die Umrandung der Aussparung überwinden kann. Die insbesondere vorgeschlagene schräge Kontaktfläche des Rastelementes und/oder der Umrandung der Aussparung sorgt dafür, dass die Rastung auch dann vollzogen und/oder gelöst werden kann, wenn das Betätigungselement nicht betätigt wird. Insbesondere kann dadurch erreicht werden, dass das Schnittstellenaußenteil ohne Betätigung des Betätigungselementes von dem Schnittstelleninnenteil abgezogen werden kann.It can be provided that the interface inner part, in particular the contact carrier, has an actuating element which can be latched into a shape-corresponding opening of the interface outer part, the actuating element having a latching element which can be latched into a recess in the interface outer part. Furthermore, the latching element and / or a border of the recess can have an inclined contact surface in the joining direction and / or opposite to the joining direction for the sliding overcoming of the border by the latching element. The actuating element creates a latching connection between the interface parts of the interface, the inner interface part and the outer interface part being coupled to one another. For example, the actuating element can be designed in such a way that the latching element is moved away from a corresponding latching element of the outer interface part in the event of bending stress or displacement of the actuating element, so that the latching connection can be released. The bending stress, or for example also a pivoting, of the actuating element can preferably result in a contact surface of the latching element being able to overcome the border of the recess. The inclined contact surface of the latching element and / or the border of the recess, which is proposed in particular, ensures that the latching can also be carried out and / or released when the actuating element is not actuated. In particular, this can achieved that the interface outer part can be removed from the interface inner part without actuating the actuating element.
Des Weiteren wird vorgeschlagen, dass eine nach außen weisende Umfangsfläche des Schnittstelleninnenteils eine in Umfangsrichtung umlaufende Nut aufweist, in welcher ein formkorrespondierendes Dichtelement angeordnet ist. Durch das formkorrespondierende Dichtelement wird unabhängig von der Qualität der Passung von Schnittstellenaußenteil und Schnittstelleninnenteil eine Dichtheit der Schnittstelle gewährleistet. Das Dichtelement ist vorzugsweise aus einem elastischen Material hergestellt, so dass ein Bewegungsspiel zwischen den Schnittstellenteilen ausgeglichen werden kann. Die für das Dichtelement vorgesehene Nut fluchtet vorzugsweise mit einer Stufe des zuvor vorgeschlagenen Stufenprofils der Querschnittsfläche des Schnittstelleninnenteils, so dass das Dichtelement gleich zu Anfang der Schnittstellenkupplung wirkt.It is also proposed that an outwardly facing peripheral surface of the interface inner part has a circumferential groove in which a shape-corresponding sealing element is arranged. The shape-corresponding sealing element ensures that the interface is sealed, regardless of the quality of the fit between the outer interface part and the inner interface part. The sealing element is preferably made of an elastic material, so that a play between the interface parts can be compensated. The groove provided for the sealing element is preferably aligned with a step of the previously proposed step profile of the cross-sectional area of the interface inner part, so that the sealing element acts immediately at the beginning of the interface coupling.
Gemäß einer weiteren Ausführungsform kann vorgesehen sein, dass eine nach außen weisende Umfangsfläche des Schnittstelleninnenteils in Umfangsrichtung orientierte Lamellen zur kraftschlüssigen Anlage an einer nach innen weisenden Umfangsfläche des Schnittstellenaußenteils aufweist. Das Schnittstelleninnenteil kann gemäß dieser Ausführungsform alternativ oder zusätzlich zu der Verwendung eines Betätigungselementes mittels der Lamellen reibschlüssig mit dem Schnittstellenaußenteil verbunden werden. Die Lamellen stehen vorzugsweise im Wesentlichen quer zu der Längserstreckung des Saugkanals. Beispielsweise kann ein Saugkanalendabschnitt des Schnittstelleninnenteils auch schraubenförmig von einer Lamelle umgegeben sein. Durch die Ausnutzung des Schnittstellenaußenteils als Steckzone können somit bauraumminimierte Schnittstelleninnenteile verwendet werden. Die Lamellen sind vorzugsweise aus einem hartelastischen Material, so dass diese einerseits den benötigten Kraftschluss zu der Innenfläche des Schnittstellenaußenteils zur Verfügung stellen können, und andererseits eine gewisse Flexibilität aufweisen, damit das Schnittstelleninnenteil in das Schnittstellenaußenteil geschoben werden kann.According to a further embodiment, it can be provided that an outwardly facing peripheral surface of the interface inner part has lamellae oriented in the circumferential direction for non-positive contact with an inwardly facing peripheral surface of the interface outer part. According to this embodiment, the interface inner part can alternatively or in addition to the use of an actuating element by means of the lamellae be frictionally connected to the interface outer part. The lamellae are preferably essentially transverse to the longitudinal extent of the suction channel. For example, a suction channel end section of the interface inner part can also be surrounded by a lamella in a helical shape. By using the outer interface part as a plug-in zone, space-minimized interface inner parts can thus be used. The lamellae are preferably made of a hard elastic material, so that on the one hand they provide the required adhesion to the inner surface of the interface outer part can provide, and on the other hand have a certain flexibility so that the interface inner part can be pushed into the interface outer part.

Wie in den
Da beispielsweise bei der Anwendung von Niederspannungs-Vorsatzgeräten 4 eine Kompatibilität zu Hochspannungs-Basisgeräten 3 aus Sicherheitsgründen ausgeschlossen werden muss, wird eine Kodierung der Schnittstelleninnenteile 6 und Schnittstellenaußenteile 5 vorgeschlagen, die nur eine definierte Kombination von Geräten 3, 4 zulässt. Somit kann eine Kombination von Niederspannungsgeräten und Hochspannungsgeräten verhindert werden. Basisgeräte 3 und Vorsatzgeräte 4, die bezüglich ihrer Arbeitspunkte von elektrischen Verbrauchern nicht aufeinander abgestimmt sind, können somit nicht über die Schnittstelle 1 miteinander verbunden werden. Somit wird verhindert, dass beispielsweise eine Kombination von Geräten 3, 4 aus verschiedenen Gerätegenerationen, die nicht aufeinander abgestimmt sind, zu einer Fehlfunktion oder Beschädigung der Geräte 3, 4 führen.Since, for example, when using low-voltage attachments 4, compatibility with high-voltage
