Definitions
- the invention relates to a vacuum cleaner with a Motor housing, possibly with a connected one Filter chamber, and a handle, the handle in a plug-in receptacle of the motor housing can be inserted and when inserting the device handle a circuit breaker mounted in the motor housing is operated.
- Such vacuum cleaners are known. So is in the WO 95/28867 a vacuum cleaner specified, which one in the motor housing can be anchored to the handle. The latter operates when plugged into the motor housing or one when pulled out of the same changeover switch arranged in the motor housing. The latter causes a condition-related electronically Activate or deactivate a motor housing side Circuit breaker. When inserting the device handle the circuit breaker is in the motor housing electronically controlled in full load position, so that another circuit breaker connected in series in the handle or in a handle the handle of the device is activated. The control of the Electric motor of the vacuum cleaner only takes place after this still on the device-side circuit breaker.
- Vacuum cleaner with a peeled off Tool handles are preferred for over-floor work used, here the power control of the naturally aspirated engine via the motor-side circuit breaker he follows.
- the circuit breaker designed as a slide switch has a remote actuation extension which is acted upon by inserting the handle of the device while simultaneously actuating the circuit breaker.
- a switchover takes place here mechanically.
- the circuit breaker in the motor housing which is designed as a slide switch, has a remote actuation extension which can be interacted with the handle, by means of which the slide switch is preferably moved into a full load position by inserting the handle into the motor housing.
- the circuit breaker on the motor housing side is connected in series with a second switch on the handle side.
- This is preferably located in the area of a handle handle. Due to the series connection and the full load position of the circuit breaker on the housing side, the circuit breaker on the handling side is activated when the handle is inserted. With the help of the latter, the power of the naturally aspirated engine can now be controlled.
- the remote actuation extension can be connected to the actuation area of the circuit breaker using the same material.
- the design can be such that when the implement handle is removed from the motor housing, the circuit breaker on the motor housing side automatically moves back to the zero position, for example by means of a tension spring or the like. This ensures that the naturally aspirated engine is switched off when the handle is removed. Its power control is then only regulated via the motor-side circuit breaker.
- the remote control extension has a detent formation on its end on the handle side for interaction with a latching recess on the handle.
- the remote control extension can be designed to be elastic at least in the area of the latching configuration, so that when the circuit breaker reaches the zero position, the latching configuration resiliently leaves the latching recess of the device handle when the handle is pulled out further.
- one end of the remote control extension on the handle side is dragged to a position when the handle is pulled out, which position is shifted back relative to a mouth of the plug receptacle.
- the remote actuation extension or its latching shape accordingly does not protrude beyond the mouth of the plug-in receptacle after the device handle has been pulled out, so that the remote-actuation extension always remains in a protected position within the plug-in receptacle.
- the end of the remote control extension on the handle side is displaceable in a gap between an inner wall of a receptacle and a plug arranged in the receptacle.
- the remote actuation extension is guided and a secure positional positioning within the plug-in receptacle, which also ensures that the latching shape is always reliably found by the latching recess of the handle.
- the plug arranged in the plug receptacle forms the electrical coupling to a coupling part which can be assigned to the plug in the handle. It is also proposed that the displacement is limited by a stop on the back of a connector. For example.
- the remote control extension can have an integrally formed stop lug, which occurs when the device handle is pulled out against the rear of the connector on the receptacle, in order to define the zero position of the circuit breaker.
- the outermost position of the end of the remote control extension on the handle side is in overlap with the connector such that contact tabs arranged on the connector protrude beyond the free end of the remote control extension. This ensures that only one handle, the latching recess of which extends beyond its plug coupling at the level, can cause the circuit breaker to be displaced.
- this training is particularly advantageous if an adapted mains coupling is inserted into the plug receptacle when the device handle is removed to supply power to the naturally aspirated motor.
- This network coupling can be designed, for example, in the form of a known IEC connector. The latter is inserted into the plug receptacle in such a way that the contact tabs of the plug on the motor housing side are captured to form the electrical coupling. The actuation extension is not acted upon here. This is also desirable since, in such a configuration, the circuit breaker on the motor housing side should initially remain in a zero position. This position should only be exited by the operator on the switch side.
- the plug has contact tabs.
- the plug be set back in the plug receptacle in such a way that the front ends of the contact lugs are at a distance from the mouth of the plug receptacle.
- the contact tabs of the plug on the motor housing side are thus arranged in such a hidden position within the plug receptacle that they cannot be accidentally bent, for example when the vacuum cleaner is put down. This also ensures a secure coupling within the plug receptacle.
- the inner wall of the plug-in receptacle offers a lateral guidance of the device handle socket. It is also proposed that the plug be cantilevered in the plug receptacle. For example.
- the plug can have a cross section which is reduced compared to the cross section of the plug receptacle.
- a remote actuation extension of a circuit breaker on the device housing side can be positioned in the annular space thus formed between the plug and the plug receptacle inner wall.
- the handle to be inserted into the plug receptacle can have a projection protruding into the annular space formed for actuating this remote control extension.
- the latter can, for example, be integrally formed on an outlet on the side of the device handle.
- the arrangement of the plug in the motor housing is preferably such that the plug is fastened in the plug receptacle via a plug base. The connector attached to the connector housing thus projects freely into the connector receptacle.
- the depth of the annular space formed between the plug and the plug-in receptacle inner wall is limited by the plug base, which is adapted in cross-section to the inner cross-section of the plug-in receptacle.
- This also provides a limit stop for a handle extension for actuating the remote control extension of the circuit breaker.
- the handle can be inserted into the plug receptacle by at least 1.5 times, preferably 2 times the largest free dimension of a handle cross section , It is further proposed that the dimension from the mouth of the plug receptacle to the base of the contact tabs corresponds approximately to the largest dimension of the cross-section of the handle.
- the handle of the device preferably enters the annular space formed between the cantilevered plug and the inner wall of the receptacle by the size of the mouth of the plug receptacle to the base of the contact lugs.
- the cantilevered length of the connector on the housing is selected accordingly.
- this configuration results in two areas with different tasks in the area of the plug-in receptacle.
- the first area assigned to the plug-in receptacle forms the electrical coupling area between the socket on the device side or the power socket that can be used instead of the device handle and the connector on the housing side.
- the second downstream area is designed as a coupling area between the handle and a remote actuation extension of a circuit breaker on the device housing side, the length of this second area, ie the length of the cantilevered area of the plug, preferably corresponding approximately to the maximum displacement path of the circuit breaker. Both areas together form the mechanical coupling area between the handle and motor housing, the entire length of which is dimensioned so that high forces and moments can be transmitted.
- the handle and / or a power socket has a locking pin which projects perpendicularly to the insertion direction and which engages in a locking receptacle of the plug receptacle.
- the locking pin provided on the handle or on the mains socket can be spring-loaded, for example, perpendicular to the insertion direction in a locking direction.

- the locking receptacle is provided with an ejector for disengaging the locking pin.
- the locking pin is displaced, preferably against a spring force, in such a way that the handle or the mains socket can then be removed.
- the ejector consists of a flexible plastic part with an integrated, for example, metallic pressing part. In a further embodiment, the latter can also be a hard plastic part.
- a power socket is provided the power socket can be inserted into the handle is.
- the handle of the device has a connector on one side for interaction with the mains socket
- the plug in a socket holder of the handle by the dimension of the largest free cross section of the Power socket is shifted back that the device handle is designed as a socket for interaction with one compared to the handle side Plug moved back by the same amount the plug receptacle, the plug of the plug receptacle however at least partially from a hollow profile of the Device handle can be run over and the socket of the Device handle over the overrun dimension in the hollow profile is shifted back.

This is particularly the case with vacuum cleaners from Advantage, as this is due to tensile loads the mains socket to unintentionally disconnect the plug connection can come.
- the locking pin on the less curved outside is arranged. It proves to be particularly advantageous here that the locking pin is approximately in the middle of the Flat plug receptacles is aligned.
- the weaker curved outline of the socket cross section forms the upper area of the mains socket the advantage that when gripping the power socket the locking pin sits ergonomically, so that this in the simplest way by means of the thumb for insertion the mains socket into a device-side and / or stick-side Plug receptacle can be depressed. It there is also the possibility of the device side and / or shaft-side plug-in with one of the locking pins to assign assigned run-up slope, which when the mains socket is inserted of the locking pin.
- An embodiment is preferred in which cross-section between the two Flat plug receptacles a non-conductive round plug receptacle is trained.
- the round plug receptacle thus formed is therefore a blind receptacle without a contact sleeve educated.
- the socket in the motor housing is the socket holder of the device handle in the essentially modeled. Only the cross section of the plug arranged in the plug receptacle reduced in cross-section, so that between the plug and the plug-in inner wall remains an annulus.

To the Mains cable connection in the upper end of the handle contrary to the handle connection only the requirements after an electrical contact and a simple one Possibility of insertion and removal. Height mechanical forces do not occur here. One insertion length of, for example, 80 mm also comes in at this point generally out of the question for reasons of space.
- the outer profile of the handle and the mains socket is identical, that the detent of Appliance handle and mains socket are identical and that There is a coding of the handle and the mains socket.
- the insertion length of the Device handle preferably at least 80 mm and the insertion length the mains socket is preferably a maximum of 35 mm. The last two dimensions contradict each other seemingly, but can be inventively agree with each other since the electrical contacting within 35 mm behind the insertion opening done, but the device tube is inserted by 80 mm must become. This measure will simultaneously in an elegant way the coding of the handle and Power socket allows.
- both optional handle and Power socket can be plugged into the motor housing, that only in the upper end of the handle the mains socket is pluggable. Because of the special The contour of the handle and the mains socket remains ensures that the use of power lines, the high number of bending cycles and loads, that occur when operating a vacuum cleaner withstand is excluded. It turns out further it is advantageous that that arranged in the basic device Potentiometer / switch module when the handle is inserted is brought into a position in which the Switch is turned on. This is required because the circuit breakers in the handle and in the motor housing are arranged in series. In the invention The circuit breaker in the Motor housing through the device stem tube inserted by 80 mm pushed into its maximum position.

Description
In einer vorteilhaften Weiterbildung des Erfindungsgegenstandes ist vorgesehen, daß der Fernbetätigungsfortsatz an seinem gerätestielseitigen Ende eine Rastausformung aufweist zur Zusammenwirkung mit einer Rastausnahme am Gerätestiel. Bei einem Einstecken des Gerätestieles in das Motorgehäuse fängt die Rastausnahme des Gerätestieles die Rastausformung des Fernbetätigungsfortsatzes ein und verlagert über diesen Fortsatz den Leistungsschalter in eine Voll-Laststellung. Ein Herausziehen des Gerätestieles bewirkt durch die formschlüssige Verbindung zwischen Rastausformung des Fernbetätigungsfortsatzes und der Rastausnahme des Gerätestieles ein Zurückverlagern des Leistungsschalters in die Null-Stellung. Hier kann bspw. der Fernbetätigungsfortsatz zumindest im Bereich der Rastausformung elastisch ausgebildet sein, so daß bei Erreichen der Null-Stellung des Leistungsschalters die Rastausformung bei einem weiteren Herausziehen des Gerätestieles federnd die Rastausnahme des Gerätestieles verläßt. Hierzu wird weiter vorgeschlagen, daß ein gerätestielseitiges Ende des Fernbetätigungsfortsatzes bei einem Herausziehen des Gerätestieles maximal in eine Stellung mitgeschleppt wird, welche gegenüber einer Mündung der Steckaufnahme zurückverlagert ist. Der Fembetätigungsfortsatz bzw. dessen Rastausformung ragt demnach nach Herausziehen des Gerätestieles aus der Steckaufnahme nicht über die Mündung desselben hinaus, womit der Fernbetätigungsfortsatz stets in einer geschützten Lage innerhalb der Steckaufnahme verbleibt. Als besonders vorteilhaft erweist es sich, daß das gerätestielseitige Ende des Fernbetätigungsfortsatzes in einem Spalt zwischen einer Steckaufnahme-Innenwand und einem in der Steckaufnahme angeordneten Stecker verschiebbar ist. Hierdurch erfährt der Fernbetätigungsfortsatz eine Führung und eine gesicherte Lagepositionierung innerhalb der Steckaufnahme, womit auch stets ein sicheres Auffinden der Rastausformung durch die Rastausnahme des Gerätestieles gegeben ist. Der in der Steckaufnahme angeordnete Stecker bildet die elektrische Kupplung zu einem in dem Gerätestiel dem Stecker zuordbaren Kupplungsteil. Weiter wird vorgeschlagen, daß die Verschiebung durch einen Anschlag an einer Steckerrückseite begrenzt ist. Bspw. kann hierzu der Fernbetätigungsfortsatz eine angeformte Anschlagnase aufweisen, welche bei einem Herausziehen des Gerätestieles gegen die Rückseite des aufnahmeseitigen Steckers tritt, zur Definition der Null-Stellung des Leistungsschalters. In einer vorteilhaften Weiterbildung des Erfindungsgegenstandes wird vorgeschlagen, daß die äußerste Stellung des gerätestielseitigen Endes des Fernbetätigungsfortsatzes in Überdeckung mit dem Stecker ist derart, daß an dem Stecker angeordnete Kontaktfahnen über das freie Ende des Fernbetätigungsfortsatzes hinausragen. Somit ist sichergestellt, daß nur ein Gerätestiel, dessen Rastausnahme ebenenmäßig über seine Steckerkupplung hinausragt, eine Verlagerung des Leistungsschalters bewirken kann. Weiter ist diese Ausbildung besonders dann von Vorteil, wenn bei abgezogenem Gerätestiel zur Stromversorgung des Saugmotors eine angepaßte Netzkupplung in die Steckeraufnahme eingeführt wird. Diese Netzkupplung kann bspw. in Form eines bekannten Kaltgerätesteckers ausgebildet sein. Letzterer wird derart in die Steckaufnahme eingeführt, daß die Kontaktfahnen des motorgehäuseseitigen Steckers zur Bildung der elektrischen Kupplung eingefangen werden. Eine Beaufschlagung des Betätigungsfortsatzes erfolgt hierbei nicht. Dies ist auch gewünscht, da bei einer solchen Konfiguration der motorgehäuseseitige Leistungsschalter zunächst in einer Null-Stellung verbleiben soll. Diese Stellung soll nur willensbetont durch schalterseitige Betätigung verlassen werden.
Der in die Steckaufnahme einzuführende Gerätestiel kann zur Betätigung dieses Fernbetätigungsfortsatzes einen in dem gebildeten Ringraum hineinragenden Vorsprung aufweisen. Letzterer kann bspw. in Verlängerung einer gerätestielseitigen Steckdose an dieser angeformt sein. Die Anordnung des Steckers in dem Motorgehäuse erfolgt bevorzugt derart, daß der Stecker über einen Steckersockel in der Steckaufnahme befestigt ist. Der an dem Steckergehäuse befestigte Stecker kragt somit frei in die Steckaufnahme ein. Der zwischen Stecker und Steckaufnahme-Innenwand gebildete Ringraum ist tiefenmäßig durch den Steckersockel, welcher querschnittsmäßig dem Innenquerschnitt der Steckaufnahme angepaßt ist, begrenzt. Hierdurch ist auch eine Anschlagbegrenzung für einen Gerätestielfortsatz zur Betätigung des Fernbetätigungsfortsatzes des Leistungsschalters gegeben. Um eine Übertragung hoher mechanischer Belastungen zwischen Gerätestiel und Motorgehäuse zu gewährleisten, wird erfindungsgemäß vorgeschlagen, daß der Gerätestiel um ein Maß in die Steckaufnahme einschiebbar ist, welches mindestens dem 1,5-fachen, vorzugsweise einem 2-fachen eines größten freien Maßes eines Gerätestielquerschnittes entspricht. Weiter wird hierzu vorgeschlagen, daß die Abmessung von der Mündung der Steckaufnahme bis zum Fuß der Kontaktfahnen etwa dem größten Maß des Gerätestielquerschnittes entspricht. Hieraus ergibt sich, daß der Gerätestiel vorzugsweise um das Maß von der Mündung der Steckaufnahme bis zum Fuß der Kontaktfahnen über den Fuß der Kontaktfahnen hinaus in den zwischen dem freikragenden Stecker und der Steckaufnahme-Innenwand gebildeten Ringraum eintritt. Die freikragende Länge des gehäuseseitigen Steckers ist entsprechend gewählt. Weiter ergeben sich durch diese Ausgestaltung im Bereich der Steckaufnahme zwei Bereiche mit unterschiedlichen Aufgaben. Der der Steckaufnahmemündung zugeordnete erste Bereich bildet den elektrischen Kupplungsbereich zwischen gerätestielseitiger Steckdose bzw. anstelle des Gerätestieles einsetzbarer Netzsteckdose und dem gehäuseseitigen Stecker. Der zweite nachgeordnete Bereich ist als Kupplungsbereich zwischen dem Gerätestiel und einem Fernbetätigungsfortsatz eines gerätegehäuseseitigen Leistungsschalters ausgebildet, wobei bevorzugt die Länge dieses zweiten Bereiches, d. h. die Länge des freikragenden Bereiches des Steckers, etwa dem maximalen Verschiebeweg des Leistungsschalters entspricht. Beide Bereiche zusammen ergeben den mechanischen Kupplungsbereich zwischen Gerätestiel und Motorgehäuse, dessen gesamte Länge so dimensioniert ist, daß hohe Kräfte und Momente übertragen werden können. In einer vorteilhaften Weiterbildung des Erfindungsgegenstandes ist vorgesehen, daß der Gerätestiel und/oder eine Netzsteckdose einen senkrecht zur Einsteckrichtung vorstehenden Rastzapfen aufweist, der in eine Rastaufnahme der Steckaufnahme einrastet. Diese Verrastung dient zur gesicherten Halterung des Gerätestiels bzw. der Netzsteckdose innerhalb der Steckaufnahme, welche Verrastung zur Lösung der Verbindung nur willensbetont aufgehoben werden kann. Der an dem Gerätestiel oder an der Netzsteckdose vorgesehene Rastzapfen kann bspw. senkrecht zur Einsteckrichtung in eine Rastrichtung federbeaufschlagt sein. Bspw. kann hierzu der Rastzapfen unterseitig mit einer Druckfeder versehen sein. Es sind jedoch Ausbildungen denkbar, bei welchen der Rastzapfen als ein aus dem Gehäusemantel teilweise freigeschnittener, in sich federnder Abschnitt ausgebildet ist. Die steckaufnahmeseitige Rastausnehmung zur Aufnahme des Rastzapfens ist in einer bevorzugten Ausbildung in dem bereits erwähnten ersten Bereich der Steckaufnahme vorgesehen, d. h. im Bereich der elektrischen Kupplung. Zur Aufhebung der Rastverbindung zwischen Gerätestiel bzw. Netzsteckdose und Steckaufnahme wird vorgeschlagen, daß die Rastaufnahme mit einem Auswerfer zum Ausrücken des Rastzapfens versehen ist. Durch Betätigung des Auswerfers wird der Rastzapfen derart, bevorzugt entgegen einer Federkraft, verlagert, daß hiernach ein Abziehen des Gerätestieles bzw. der Netzsteckdose erfolgen kann. Hier erweist es sich als vorteilhaft, daß der Auswerfer aus einem flexiblen Kunststoffteil besteht mit einem eingebundenen, bspw. metallischen Drückteil. Letzteres kann in einer weiteren Ausführung auch ein Hartkunststoffteil sein.
