Description

Koffer mit einer Aufnahmebucht für ein akkubetriebenes Elektrowerkzeug sowie Koffersystem mit mindestens zwei solchen KoffernCase with a receptacle for a battery-operated power tool and case system with at least two such cases
Stand der TechnikState of the art
Die Erfindung geht .aus von einem Koffer mit einer ersten Aufnahmebucht für ein akkubetriebenes Elektrowerkzeug mit den gattungsbildenden Merkmalen des Anspruchs 1.The invention is based on a case with a first receiving bay for a battery-operated power tool with the generic features of claim 1.
Es sind Koffer bekannt, die eine oder mehrere Aufnahmebuchten für akkubetriebene Elektrowerkzeuge aufweisen. In diese kann das Elektrowerkzeug entweder zusammen mit dem ihn betreibenden Akku oder getrennt von diesem aufgenommen werden. Dadurch wird das Transportieren eines akkubetriebenen Elek- trowerkzeugs vereinfacht. Zum Laden des Akkus muss dieser j edoch aus dem Koffer herausgenommen werden und an ein Lade- gerät angeschlossen werden. Falls der Akku noch im Elektrowerkzeug eingeschoben ist, muss das Elektrowerkzeug mit aus dem Koffer genommen und der Akku anschließend auch noch aus diesem herausgezogen werden. Dies ist zeitaufwendig.Cases are known which have one or more receiving bays for battery-operated power tools. The power tool can be accommodated in this either together with the battery that operates it or separately from it. This simplifies the transport of a battery-operated power tool. To charge the battery, however, it must be removed from the case and connected to a charger. If the battery is still inserted in the power tool, the power tool must be removed from the case and the battery must then be removed from it. This is time consuming.
Des Weiteren sind Geräte bekannt, bei denen der Akku im eingesteckten Zustand geladen werden kann. Beispielsweise handelt es sich hierbei um einen kleinen Staubsauger mit einer1 Wandhalterung, eine Bohrmaschine mit Maschinenhalter für eine Wandmontage und einen Akkuschrauber mit Wandhalter und Ladegerät. Dadurch wird zwar der Aufwand verringert, der durch das Entfernen des Akkus aus dem Elektrogerät nötig ist, jedoch ist das Elektrogerät während des Ladens nicht gut gegen Umwelteinflüsse geschützt. Außerdem kann das Elektrogerät nur schwer von einem Ort zum anderen transportiert werden.Furthermore, devices are known in which the battery can be charged when plugged in. For example, this is a small vacuum cleaner with a 1 wall bracket, a drill with machine holder for wall mounting and a cordless screwdriver with wall bracket and charger. This does reduce the effort involved by removing the battery from the electrical device, but the electrical device is not well protected against environmental influences during charging. In addition, the electrical device is difficult to move from one place to another.
Vorteile der ErfindungAdvantages of the invention
Ein er indungsgemäßer Transportkoffer mit den Merkmalen des Anspruchs 1 hat dem gegenüber den Vorteil, dass ein akkubetriebenes Elektrowerkzeug samt eingesteckten Akku in einem geschlossenen Transportkoffer geladen werden kann.A transport case according to the invention with the features of claim 1 has the advantage over the fact that a battery-operated power tool together with the inserted battery can be charged in a closed transport case.
In dem Transportkoffer wird der Arbei s-Akkύ,-- der. in dem akkubetriebenen Elektrowerkzeug eingesteckt ist, beim Einlegen in die Aufnahmebucht über eine erste Leitung mit dem Ladegerät verbunden. Dieses Ladegerät erhält den zum Aufladen des Arbeits-Akkus benötigten Strom über eine Netzan- schlussvorrichtung, die mit einer Stromquelle verbunden werden kann. Hierbei handelt es sich in der Regel um einen Stecker, der in eine Steckdose eingesteckt wird. Somit kann der Arbeits-Akku des Elektrowerkzeugs aufgeladen werden, während das Elektrowerkzeug sicher aufbewahrt ist. Dabei muss nicht einmal der Arbeits-Akku aus , dem Elektro- Werkzeug herausgenommen werden. Es ist nur Sorge dafür zu tragen, dass der Arbeits-Akku außenliegende Kontakte aufweist, die im eingelegten Zustand des Elektrowerkzeugs in der ersten Aufnahmebucht mit dazu korrespondierenden Kontakten in der ersten Aufnahmebucht in Kontakt steht.In the transport case, the work is battery. is plugged into the battery-operated power tool, connected to the charger via a first line when it is inserted into the receiving bay. This charger receives the power required to charge the work battery via a mains connection device that can be connected to a power source. This is usually a plug that is inserted into an electrical outlet. This allows the power tool's rechargeable battery to be charged while the power tool is stored safely. It is not even necessary to remove the working battery from the power tool. It is only necessary to ensure that the working battery has external contacts which, in the inserted state of the power tool in the first receiving bay, are in contact with corresponding contacts in the first receiving bay.
Eine bevorzugte Ausgestaltung des Transportkoffers sieht vor, dass die Netzanschlussvorrichtung einen an einem Kabel angeordneten Stecker aufweist, der auf einer Kabelaufrollvorrichtung abrollt. Dadurch kann der Transportkoffer auch in einem Abstand zu der Stromquelle stehen, die die Strom- Versorgung des Ladegeräts im Inneren des Transportkoffers speist. Somit ergibt sich eine größere Flexibilität für den Besitzer des Transportkoffers.A preferred embodiment of the transport case provides that the mains connection device has a plug which is arranged on a cable and rolls on a cable reel-up device. As a result, the transport case can also be at a distance from the power source that the power Power supply to the charger inside the transport case. This results in greater flexibility for the owner of the transport case.
Besonders vorteilhaft ist es, wenn die Kabelaufrollvorrichtung im Inneren des Koffers angeordnet ist und auf den Stekker eine Kraft ausübt, die ihn in eine außenliegende Stekkergarage zieht. Dadurch wird gewährleistet, dass der Stekker stets in den Transportkoffer zurückgezogen wird, wenn er nicht durch eine feste Verbindung mit einem Stromversor- gungsgerät verbunden ist. Somit muss das Kabel nicht ständig von Hand aufgewickelt werden.It is particularly advantageous if the cable reel-up device is arranged inside the case and exerts a force on the connector which pulls it into an external connector garage. This ensures that the plug is always pulled back into the transport case when it is not connected to a power supply unit by a fixed connection. This means that the cable does not have to be continuously wound up by hand.
Besonders vorteilhaft ist es, wenn er mindestens eine weite- re Aufnahmebucht für ein weiteres akkubetriebenes Elektrowerkzeug und/oder mindestens eine Ladebuchten für einen Ersatz-Akku aufweist, die jeweils mit dem Ladegerät über eine weitere Leitung verbunden sind. Dadurch ist es möglich, mehrere 'akkubetriebene Elektrowerkzeuge bzw. für diese benötig- te Ersatz-Akkus gleichzeitig bei geschlossenem Transportkoffer zu laden. Außerdem ist dadurch ein sehr einfaches Transportieren von unterschiedlichen Geräten sowie Ersatz-Akkus mit möglichst geringem Aufwand möglich.It is particularly advantageous if it has at least one further receiving bay for a further battery-operated power tool and / or at least one charging bay for a replacement battery, each of which is connected to the charger via a further line. This makes it possible to charge several ' battery-operated power tools or the replacement batteries required for them at the same time with the transport case closed. This also makes it very easy to transport different devices and replacement batteries with as little effort as possible.
Besonders vorteilhaft ist es, wenn das Ladegerät mit einer außenliegenden Ladezustandsanzeige verbunden ist, die den Ladezustand mindestens eines sich in einer Aufnahmebucht und/oder Ladebucht befindlichen Arbeits-Akkus bzw. Ersatz- Akkus anzeigt. Dadurch wird der Benutzer ständig auf dem Laufenden gehalten, wie die einzelnen Ladezustände der imIt is particularly advantageous if the charger is connected to an external charge status display which shows the charge status of at least one working battery or replacement battery located in a receiving bay and / or charging bay. As a result, the user is kept up to date on how the individual charge levels in the
Transportkoffer befindlichen Akkus sind. Er kann dadurch nicht durch ein nicht einsatzfähiges Elektrowerkzeug überrascht werden, weil kein oder ein nur unzureichend aufgeladener Akku zur Hand ist . Weiterhin ist es vorteilhaft, wenn die Netzanschlussvorrich- tung als ein erster Steckkontakt ausgebildet ist, der mit einem zweiten, inversen Steckkontakt an einem weiteren, nach einem der vorstehenden Ansprüche ausgebildeten Koffer ver- bindbar ist. Durch die Verwendung von zwei oder mehrerer solcher Transportkoffer ist es möglich, mit nur einer Netz- anschlussvorrichtung ein ganzes Set von Transportkoffern zu einem Akkusystem zu stapeln..Dadurch können eine Vielzahl von akkubetriebenen Elektrowerkzeugen und Ersatzakkus gleichzeitig über nur eine einzige Steckdose geladen werden. Ein solches Koffersystem hat den weiteren Vorteil, dass es sehr kompakt ist und wenig Platz beansprucht. Beispielsweise kann das Koffersystem in einem Werkstattregal bei sehr geringem Platzbedarf betrieben" werden.Batteries are in the transport case. He cannot be surprised by a non-operational power tool because there is no or an insufficiently charged battery at hand. Furthermore, it is advantageous if the mains connection device is designed as a first plug contact which can be connected to a second, inverse plug contact on a further case designed according to one of the preceding claims. By using two or more of these transport cases, it is possible to stack an entire set of transport cases into a battery system with just one mains connection device. This means that a large number of battery-operated power tools and replacement batteries can be charged at the same time using just a single socket. Such a case system has the further advantage that it is very compact and takes up little space. For example, the case system can be operated on a workshop shelf with very little space " .
Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche .Further advantageous embodiments of the invention are the subject of the dependent claims.
Zeichnungendrawings
Ein Ausführungsbeispiel der Erfindung ist in der nachstehenden Beschreibung an Hand der zugehörigen Zeichnung näher erläutert.An embodiment of the invention is explained in more detail in the following description with reference to the accompanying drawings.
Die einzige Figur zeigt den schematischen Aufbau eines er- findungsgemäßen Transportkoffers .The single figure shows the schematic structure of a transport case according to the invention.
Ein Transportkoffer 1 für ein akkubetriebenes Elektrowerkzeug 3 weist eine erste Aufnahmebucht 2 zur Aufnahme des Elektrowerkzeugs 3 auf. Das Elektrowerkzeug 3 kann dabei mit einem einges eckten Arbeits-Akku 4 in die Aufnahmebucht 2 eingesteckt werden. An der Aufnahmebucht 2 sind Kontakte (nicht gezeigt) angeordnet, die mit Kontakten am Arbeits-Akku 4 (nicht gezeigt) im eingelegten Zustand des Elektrowerkzeugs 3 in Kontakt stehen. Diese Kontakte sind über eine erste Leitung 7 mit einem Ladegerät 6 verbunden. Das Ladegerät 6 ist mit einer Netzanschlussvorrichtung 5 verbunden. Im dargestellten Ausführungsbeispiel handelt es sich bei der Netzanschlussvorrichtung 5 um einen Stecker 8, der über ein Kabel 9 auf einer Kabelaufrollvorrichtung 10 angebracht ist. Der Stecker 8 wird dabei von einer Kraft, in der Regel einer Federkraft, die die Kabelaufrollvorrichtung 10 auf das Kabel 9 ausübt, in eine am Transportkoffer 1 außenliegende Steckergarage 11 hineinge- zogen. Dieses Prinzip ist mit jenem vergleichbar, das für Staubsauger bekannt ist. Zum Laden des Arbeits-Akkus 4 in der Aufnahmebucht 2 wird der Stecker 8 aus der Steckergarage 11 gegen die Kraft der Kabelaufrollvorrichtung .10 herausgezogen und in eine Steckdose gesteckt. Damit erhält das Ladegerät 6 den zur Aufladung des Arbeits-Akkus 4 benötigten Strom. Das Ladegerät .6 ist mit einer außen am Transportkoffer 1 angebrachten Ladezustandsanzeige 15 verbunden. Damit kann ständig der Ladezustand des Arbeits- Akkus 4 überprüft werden. Der Benutzer des Transportkof- fers 1 ist somit vor einer Überraschung sicher, wenn er das Elektrowerkzeug 3 benutzen will und dieses auf Grund eines leeren Arbeits-Akkus 4 nicht in Betrieb genommen werden kann.A transport case 1 for a battery-operated power tool 3 has a first receiving bay 2 for receiving the power tool 3. The power tool 3 can be inserted into the receptacle 2 with an inserted working battery 4. Contacts (not shown) are arranged on the receiving bay 2 and are in contact with contacts on the working battery 4 (not shown) when the power tool 3 is in the inserted state. These contacts are connected to a charger 6 via a first line 7. The charger 6 is connected to a mains connection device 5. In the exemplary embodiment shown, the mains connection device 5 is a plug 8, which is attached to a cable reeling device 10 via a cable 9. The plug 8 is pulled into a plug garage 11 on the outside of the transport case 1 by a force, usually a spring force, which the cable reeling device 10 exerts on the cable 9. This principle is comparable to that known for vacuum cleaners. To charge the working battery 4 in the receiving bay 2, the plug 8 is pulled out of the plug garage 11 against the force of the cable retractor .10 and plugged into a socket. The charger 6 thus receives the current required to charge the working battery 4. The charger .6 is connected to a charge status indicator 15 attached to the outside of the transport case 1. The charge state of the working battery 4 can thus be checked continuously. The user of the transport case 1 is therefore protected from a surprise when he wants to use the power tool 3 and this cannot be put into operation due to an empty working battery 4.
Zusätzlich zu der Aufnahmebucht 2 weist der Transportkof- fer 1 noch zwei Ladebuchten 12, 12a für jeweils einen Ersatz-Akku 13, 13a auf. Die Ladebuchten 12, 12a sowie die Ersatz-Akkus 13, 13a sind genauso wie die oben beschriebene Aufnahmebucht 2 und der Arbeits-Akku 4 mit jeweils zu— sammenwirkenden Kontakten (nicht gezeigt) versehen. DieIn addition to the receiving bay 2, the carrying case 1 also has two charging bays 12, 12a, each for a replacement battery 13, 13a. The charging bays 12, 12a and the replacement rechargeable batteries 13, 13a, like the receiving bay 2 described above and the working rechargeable battery 4, are each provided with interacting contacts (not shown). The
Ladebuchten 12, 12a sind auch über weitere Leitungen 14, 14a jeweils mit dem Ladegerät 6 verbunden. Für jede der beiden Ladebuchten 12, 12a ist eine eigene LadezuStandsanzeige 16, 16a vorhanden. Diese wirken wie die oben zum Ar- beits-Akku 4 beschriebene Ladezustandsanzeige 15. Dadurch ist es möglich, nicht nur den Arbeits-Akku 4 des Elektrowerkzeugs 3 zu laden, sondern gleichzeitig zwei Ersatz- Akkus 13, 13a. Damit wird gewährleistet, dass das Elektrowerkzeug 3 bedeutend länger eingesetzt werden kann, da der leere Arbeits-Akku 4 durch einen Ersatz-Akku 13, 13a ersetzt werden kann, der immer im Transportkoffer 1 problemlos und sicher verpackt mitgeführt werden kann.Charging bays 12, 12a are also each connected to the charger 6 via further lines 14, 14a. A separate charge status indicator 16, 16a is provided for each of the two charging bays 12, 12a. These act like the charge status display 15 described above for the working battery 4 it is possible not only to charge the working battery 4 of the power tool 3, but also two spare batteries 13, 13a at the same time. This ensures that the power tool 3 can be used significantly longer, since the empty working battery 4 can be replaced by a replacement battery 13, 13a, which can always be carried in the transport case 1 easily and safely packed.
Neben der Ausführung mit nur einer ersten Aufnahmebucht 2 für ein akkubetriebenes Elektrowerkzeug 3 ist es genauso gut möglich, mehrere Aufnahmebuchten für weitere Elektro- werkzeuge 3 im Transportkoffer 1 vorzusehen. Beispielsweise kann es sich bei den Elektrowerkzeugen 3 um eine Bohrmaschine, einen Schrauber und/oder einen Staubsauger han- dein. Ebenso ist es möglich, statt zweier Ladebuchten 12, 12a für Ersatz-Akkus 13, 13a eine andere Anzahl von Ladebuchten 12, 12a im Transportkoffer 1 vorzusehen. Dies hängt von der Große des Transportkoffers 1 und den beabsichtigten Einsatzzeiten für das oder die Elektrowerkzeucje 3 ab.In addition to the design with only a first receiving bay 2 for a battery-operated power tool 3, it is equally possible to provide several receiving bays for further electric tools 3 in the transport case 1. For example, the power tools 3 can be a drill, a screwdriver and / or a vacuum cleaner. It is also possible to provide a different number of charging bays 12, 12a in the transport case 1 instead of two charging bays 12, 12a for replacement batteries 13, 13a. This depends on the size of the transport case 1 and the intended operating times for the power tool or tools 3.
Neben der komfortablen Überwachung der Akkus 4, 13, 13a bei geschlossenem Transportkof er 1 weist das oben beschriebene erfindungsgemäße Ausführungsbeispiel weitere Vorteile auf: Zum Einen ist zum Laden des Elektrowerkzeucs 3 keine zusätzliche Wandhalterung nötig, zum Anderen handelt sich um eine sehr gute Peripherie für Sets aus akkubetriebenen Elektrogeräten 2, so genannte Combos. Des Wei- - teren hat man auf einer Baustelle in einen einzigen Trans- portkoffer 1 alle benötigten akkubetriebenen Elektrowerkzeuge 2 an der Hand, wobei ein gleichzeitiges Nachladen von Ersatz-Akkus 13, 13a während der Arbeit mit dem Arbeits-Akku 4 erfolgt. Außerdem kann ein Laden der- Elektro- werkzeuge 3 bei sehr geringem Platzbedarf im Werkstattre— gal erfolgen, wobei die Elektrowerkzeuge 3 sehr gut gegen Umwelteinflüsse geschützt sind.In addition to the convenient monitoring of the rechargeable batteries 4, 13, 13a when the transport case 1 is closed, the exemplary embodiment according to the invention described above has further advantages: on the one hand, no additional wall bracket is required for charging the power tool 3, and on the other hand it is a very good periphery for sets from battery-operated electrical appliances 2, so-called combos. Furthermore, on a construction site, you have all the required battery-operated power tools 2 at hand in a single transport case 1, with a simultaneous recharging of replacement batteries 13, 13a while working with the work battery 4. In addition, charging the electrical tools 3 with very little space required in the workshop gal take place, the power tools 3 being very well protected against environmental influences.
Eine nicht dargestellte Möglichkeit besteht darin, mehrere Transportkoffer 1 über Steckkontakte miteinander in der Art einer Serienschaltung zu verbinden, wobei diese dann besonders platzsparend direkt aneinander anstoßend aufbewahrt werden können. Die Steckkontakte sind dazu vorteilhafterweise als zueinander inverse Steckkontakte ausgebil- det, die fest oder auch mittels einer oben beschriebenen Kabelaufrollvorrichtung am Transportkoffer 1 ausgebildet sind. One possibility, not shown, is to connect a plurality of transport cases 1 to one another in the manner of a series connection by means of plug contacts, in which case they can then be stored directly abutting one another in a particularly space-saving manner. For this purpose, the plug contacts are advantageously designed as plug contacts which are inverse to one another and which are embodied in a fixed manner or also on the transport case 1 by means of a cable reeling device described above.
