Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem Transportkoffer für ein akkubetriebenes Elektrowerkzeug mit den gattungsbildenden Merkmalen des Anspruchs 1, sowie einem Ladekoffer mit den gattungsbildenden Merkmalen des Anspruchs 3.The invention relates to a transport case for a battery-powered power tool with the generic features of claim 1, and a charging case with the generic features of claim 3.

Ein solcher Transportkoffer ist bekannt aus der US-A-5533843 und ein solcher Ladekoffer ist bekannt aus der DE-A1-19614435 .Such a transport case is known from the US-A-5533843 and such a charging case is known from the DE-A1-19614435 ,

Es sind so genannte Kombo-Kits bekannt, bei denen mehrere akkubetriebene Elektrowerkzeuge in einem Set verkauft werden. Dabei handelt es sich um eine festgelegte Auswahl an Elektrowerkzeugen, die in einem einzigen Transportkoffer geliefert werden. Dadurch muss nicht jedem einzelnen Elektrowerkzeug ein separater Akku-Pack bzw. ein Ladegerät beigelegt werden. Ein Käufer kann dadurch mehrere akkubetriebene Elektrowerkzeuge zu einem günstigeren Preis kaufen, da die Anzahl der Akku-Packs bzw. Ladegeräte geringer ist, als wenn er sich jeweils einzeln ein akkubetriebenes Elektrowerkzeug mit dem dazugehörigen Akku-Pack bzw. Ladegerät zulegen würde. Auch der Hersteller spart dabei Kosten hinsichtlich der Logistik und der Verpackung ein. Dadurch, dass die Elektrowerkzeuge preisgünstiger angeboten werden können, werden mehr Elektrowerkzeuge abgesetzt und sowohl der Umsatz als auch die Stückzahl des Herstellers wird erhöht.There are so-called combo kits known in which several battery-powered power tools are sold in a set. It is a set of power tools that are delivered in a single carrying case. As a result, a separate battery pack or charger does not have to be enclosed with each individual power tool. A buyer can thereby buy several battery-powered power tools at a cheaper price, since the number of rechargeable batteries or chargers is lower than if he would individually buy a battery-powered power tool with the associated battery pack or charger. The manufacturer also saves costs in terms of logistics and packaging. The fact that the power tools can be offered cheaper, more power tools are sold and both the turnover and the number of units of the manufacturer is increased.

Für einen Käufer ergeben sich jedoch auch gravierende Nachteile. Zum Einen ist der Transportkoffer unhandlich und schwer, da in ihm ein schweres Ladegerät bzw. Akku-Packs beigelegt sein müssen. Zum Anderen kann der Kunde nur die speziell in dem Set angebotenen Elektrowerkzeuge in ihrer Gesamtheit erwerben. Dadurch wird er möglicherweise dazu genötigt, ein Elektrowerkzeug mit anzuschaffen, das er gar nicht benötigt.For a buyer, however, there are also serious disadvantages. For one, the transport case is unwieldy and difficult, because in it a heavy charger or battery packs must be enclosed. On the other hand, the customer can only purchase the power tools specifically offered in the set in their entirety. This may force him to purchase a power tool he does not need.

Vorteile der ErfindungAdvantages of the invention

Ein erfindungsgemäßer Transportkoffer mit den Merkmalen des Anspruchs 1 sowie ein erfindungsgemäßer Ladekoffer mit den Merkmalen des Anspruchs 3 haben demgegenüber den Vorteil, dass eine individuelle Zusammenstellung der benötigten akkubetriebenen Elektrowerkzeuge durch den Käufer möglich ist und er nicht ständig einen schweren Transportkoffer mit einer Vielzahl von Elektrowerkzeugen sowie Akku-Packs bzw. Ladegeräten mit sich führen muss.An inventive transport case with the features of claim 1 and a charging case according to the invention with the features of claim 3 have the advantage that an individual compilation of the required battery-powered power tools by the buyer is possible and he is not constantly a heavy transport case with a variety of power tools and Battery packs or chargers must carry with them.

Dies wird beim erfindungsgemäßen Transportkoffer dadurch erreicht, dass er über seine erste Verbindungsvorrichtung, die an einer seiner Außenflächen angeordnet ist, mit einem erfindungsgemäßen Ladekoffer über dessen zweite Verbindungsvorrichtung, die ebenfalls an einer Außenfläche angeordnet ist, verbunden werden kann. Dadurch wird ein erfindungsgemäßes Set aus mindestens einem Transportkoffer und einem Ladekoffer gebildet. Somit kann ein Aufladen eines akkubetriebenen Elektrowerkzeuges in der Aufnahmebucht des Transportkoffers erfolgen, wenn das Netzkabel des Ladekoffers mit einer Stromquelle verbunden ist. Zum Transport kann das Set wieder in Transportkoffer und Ladekoffer zerlegt werden. Falls nur kleine Arbeiten erledigt werden müssen, kann auf die Mitnahme des schweren Ladekoffers verzichtet werden und nur der Transportkoffer mit dem spezifisch benötigten Elektrowerkzeug mitgeführt werden. Mit dem Ladekoffer kann immer genau der Transportkoffer zu einem Set zusammengefasst werden, der für das gerade benötigte akkubetriebene Elektrowerkzeug gebraucht wird. Dadurch muss ein Käufer nicht ein großes Kombo-Kit mit unterschiedlichen Elektrowerkzeugen kaufen, sondern kann jeweils einen einzelnen Koffer mit nur einem akkubetriebenen Elektrowerkzeug kaufen. Wenn der Transportkoffer mit dem Ladekoffer zu einem Set vereinigt wird, bildet die erste Verbindungsvorrichtung am Transportkoffer mit der zweiten Verbindungsvorrichtung am Ladekoffer eine sichere und lösbare Verbindungseinheit. Damit wird gewährleistet, dass ein Aufladen des sich im Transportkoffer befindlichen akkubetriebenen Elektrowerkzeugs erfolgt.This is achieved in the transport case according to the invention in that it can be connected via its first connecting device, which is arranged on one of its outer surfaces, with a charging case according to the invention via the second connecting device, which is also arranged on an outer surface. As a result, an inventive set of at least one transport case and a charging case is formed. Thus, charging of a battery powered power tool in the receiving bay of the carrying case may occur when the power cord of the charging case is connected to a power source. For transport, the set can be disassembled again in transport case and charging case. If only small jobs need to be done, it is possible to dispense with the carrying of the heavy loading case and only carry the transport case with the specifically required power tool. With the charging case, it is always possible to combine precisely the transport case into a set, which is needed for the battery-powered power tool just needed. Thus, a buyer does not have to buy a large combo kit with different power tools, but can each buy a single case with just a battery-powered power tool. When the transport case is combined with the charging case to form a set, the first connection device forms a secure and detachable connection unit on the transport case with the second connection device on the charging case. This ensures that charging of the battery-powered power tool located in the transport case takes place.

Vorteilhaft ist ein Transportkoffer, der an jeder seiner Außenflächen eine weitere erste Verbindungsvorrichtung und weitere elektrische Kontakte aufweist, die mit den ersten elektrischen Kontakten verbunden sind. Dadurch ist es möglich, an diesen Transportkoffer einen weiteren Transportkoffer für ein weiteres akkubetriebenen Elektrowerkzeug anzudocken. Dabei kann es sich um ein anderes oder auch um ein gleiches Elektrowerkzeug handeln. Somit ist es möglich, sich ein eigenes, individuelles Set von gerade benötigten Elektrowerkzeugen zusammenzustellen. Dadurch, dass die zweiten elektrischen Kontakte mit den ersten elektrischen Kontakten verbunden sind, ist gewährleistet, dass beim angeschlossenen Ladekoffer auch der weitere Transportkoffer mit Strom versorgt wird und somit ein sich darin befindliches akkubetriebenes Elektrowerkzeug geladen wird.Advantageously, a transport case having at each of its outer surfaces a further first connection device and further electrical contacts which are connected to the first electrical contacts. This makes it possible to dock on this transport case another transport case for another battery-powered power tool. It can be a different or even the same power tool. Thus, it is possible to assemble your own, individual set of just needed power tools. The fact that the second electrical contacts are connected to the first electrical contacts, it is ensured that when the charging case and the other transport case is supplied with power and thus it is located in a battery-powered power tool is charged.

Eine vorteilhafte Weiterbildung des Ladekoffers sieht vor, dass er mindestens eine Ladebucht für einen Akku-Pack aufweist. Dadurch ist es möglich, gleichzeitig mit einem sich in einem Transportkoffer befindlichen akkubetriebenen Elektrowerkzeug noch einen Ersatzakku-Pack zu laden. Falls an den Ladekoffer kein Transportkoffer angeschlossen ist, kann auch nur der Ersatzakku-Pack im Ladekoffer geladen werden.An advantageous development of the charging case provides that it has at least one charging bay for a battery pack. This makes it possible to load a spare battery pack at the same time as a battery-powered power tool in a transport case. If no carrying case is connected to the charging case, only the spare battery pack can be charged in the charging case.

Eine weitere vorteilhafte Weiterbildung eines Ladekoffers sieht vor, dass das Netzkabel gegen eine Kraft ausziehbar mit ihm verbunden ist. Dadurch wird das Netzkabel immer wieder automatisch zurückgezogen, wenn es nicht in einer Steckdose eingesteckt ist. Somit muss das Netzkabel nicht von Hand immer wieder auf den Ladekoffer aufgewickelt werden, sondern verstaut sich automatisch selbst in diesem. Dieses Prinzip ist von Staubsaugern bekannt.A further advantageous embodiment of a charging case provides that the power cord is connected to a force extendable connected to him. This automatically retracts the power cord whenever it is not plugged into a wall outlet. Thus, the power cord does not have to be wound up by hand repeatedly on the charging case, but stows itself automatically in this. This principle is known from vacuum cleaners.

Besonders vorteilhaft sind die erste bzw. zweite Verbindungsvorrichtung als eine Rastvorrichtung oder eine Schiene ausgebildet. Damit können Ladekoffer und Transportkoffer bzw. auch Transportkoffer untereinander sehr einfach aneinander angedockt werden. In diesem Fall kann dies dann in besonders einfacher Weise durch Anklipsen, Anstecken oder Aufschieben erfolgen.Particularly advantageously, the first or second connection device are designed as a latching device or a rail. This charging case and carrying case or even transport case with each other can be very easily docked together. In this case, this can then be done in a particularly simple manner by clipping on, plugging or pushing.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.

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 Figuren zeigen:

eine mögliche Ausgestaltung eines Ladekoffers.
The figures show:
FIG. 1
a schematic representation of the composition of a set of a charging case and several transport cases and
FIG. 2
a possible embodiment of a charging case.

In Figur 1 ist ein zentraler Transportkoffer 1, der im Folgenden als Basiskoffer 1 bezeichnet wird, dargestellt. Dieser Basiskoffer 1 weist in seinem Inneren eine Aufnahmebucht für ein akkubetriebenes Elektrowerkzeug (nicht gezeigt) auf. In der Aufnahmebucht sind elektrische Ladekontakte (nicht gezeigt) angeordnet, die bei einem eingelegten Elektrowerkzeug mit entsprechenden Ladekontakten an diesem bzw. dessen Akku-Pack elektrisch in Kontakt sind. An einer seiner schmalen Außenflächen weist der Basiskoffer 1 eine erste Verbindungsvorrichtung 2 mit ersten elektrischen Kontakten 3 auf. Die ersten elektrischen Kontakte 3 sind mit den Ladekontakten der Aufnahmebucht verbunden. An diese schmale Außenfläche des Basiskoffers 1 wird entlang eines ersten Pfeiles P1 ein Ladekoffer 4 herangeführt und an den Basiskoffer 1 angedockt. Beim Andocken kann es sich um ein Anklipsen, Anstecken oder Aufschieben handeln. Dazu sind sowohl an der schmalen Außenfläche des Basiskoffers 1 eine erste Andockvorrichtung als auch an einer Außenfläche des Ladekoffers 4 eine zweite Andockvorrichtung (nicht gezeigt) ausgebildet. Diese Andockvorrichtungen sind so ausgebildet, dass sie zusammenwirken und eine sichere, lösbare Verbindungseinheit ergeben. Solche Andockvorrichtungen sind bekannt, beispielsweise handelt es sich um Rastvorrichtungen oder Schienen, so dass hier nicht näher darauf eingegangen werden muss. Im angedockten Zustand sind die ersten elektrischen Kontakte 3 des Basiskoffers 1 mit den zweiten elektrischen Kontakten 8 einer zweiten Verbindungsvorrichtung 7 am Ladekoffer 4 (siehe Figur 2) in elektrischem Kontakt. Dadurch wird ein Akku-Pack in einem Elektrowerkzeug, das in der Aufnahmebucht des Basiskoffers 1 liegt, durch das Ladegerät 4 geladen.In FIG. 1 is a central transport case 1, which is referred to below as the base case 1 shown. This base case 1 has in its interior a receiving bay for a battery-powered power tool (not shown). In the receiving bay electrical charging contacts (not shown) are arranged, which are electrically in contact with an inserted power tool with corresponding charging contacts on this or its battery pack. At one of its narrow outer surfaces, the base case 1 has a first connection device 2 with first electrical contacts 3. The first electrical contacts 3 are connected to the charging contacts of the receiving bay. At this narrow outer surface of the base box 1 a loading case 4 is brought along a first arrow P1 and docked to the base case 1. Docking can be clipping, hooking or suspending. For this purpose, both on the narrow outer surface of the base case 1, a first docking device and on an outer surface of the loading case 4, a second docking device (not shown) are formed. These docking devices are designed to work together to provide a secure, detachable connection unit. Such docking devices are known, for example, there are locking devices or rails, so that it need not be discussed in detail here. In the docked state, the first electrical contacts 3 of the base case 1 with the second electrical contacts 8 of a second connecting device 7 on the charging case 4 (see FIG. 2 ) in electrical contact. Thereby, a battery pack in a power tool, which is located in the receiving bay of the base 1, loaded by the charger 4.

Der Basiskoffer 1 weist nicht nur an seiner schmalen Außenfläche eine erste Verbindungsvorrichtung 2 auf, sondern auch noch an weiteren Außenflächen weitere erste Verbindungsvorrichtungen 2a mit weiteren elektrischen Kontakten 3a. Stellvertretend hierfür ist in Figur 1 nur eine einzige weitere erste Verbindungsvorrichtung 2a dargestellt. An den Basiskoffer 1 können somit weitere Transportkoffer 1a, 1b, 1c an diesen entlang der jeweiligen Richtungen, die durch die Pfeile P2, P3, P4 dargestellt sind, angedockt werden. Dafür bestehen zwischen dem Basiskoffer 1 und den jeweiligen weiteren Transportkoffern 1a, 1b, 1c nicht dargestellte Andockvorrichtungen, die der oben Beschriebenen entsprechen. Die weiteren Transportkoffer 1a, 1b, 1c weisen jeweils weitere erste Verbindungsvorrichtungen 2a mit weiteren elektrischen Kontakten 3a auf. Im angedockten Zustand haben deren jeweilige weiteren elektrischen Kontakte 3a mit den weiteren elektrischen Kontakten 3a des Basiskoffers 1 elektrischen Kontakt. In den weiteren Transportkoffern 1a, 1b, 1c ist jeweils auch eine Aufnahmebucht für ein akkubetriebenes Elektrowerkzeug (nicht dargestellt) mit Ladekontakten vorhanden, wie dies auch schon oben zum Basiskoffer 1 ausgeführt wurde. Damit ist es möglich, nicht nur das Elektrowerkzeug im Basiskoffer 1 über ein angeschlossenes Ladegerät 4 zu laden, sondern zusätzlich die Elektrowerkzeuge in den zusätzlichen Transportkoffern 1a, 1b, 1c. In diesen kann ein beliebiges akkubetriebenen Elektrowerkzeug enthalten sein. Es ist möglich, dass es sich um ein gleiches Elektrowerkzeug wie im Basiskoffer 1 handelt oder um ein davon verschiedenes.The base case 1 not only has a first connecting device 2 on its narrow outer surface, but also further first connecting devices on further outer surfaces 2a with further electrical contacts 3a. Representative of this is in FIG. 1 only a single further first connection device 2a is shown. Thus, further transport cases 1a, 1b, 1c can be docked to the base case 1 along the respective directions, which are represented by the arrows P2, P3, P4. For this exist between the base case 1 and the respective other transport cases 1a, 1b, 1c docking devices not shown, which correspond to those described above. The further transport cases 1a, 1b, 1c each have further first connection devices 2a with further electrical contacts 3a. In the docked state, their respective further electrical contacts 3a have electrical contact with the further electrical contacts 3a of the base case 1. In the other transport cases 1a, 1b, 1c is also a receiving bay for a battery-powered power tool (not shown) with charging contacts available, as was already above the base case 1 was executed. This makes it possible to load not only the power tool in the base case 1 via a connected charger 4, but also the power tools in the additional transport cases 1a, 1b, 1c. These may include any battery powered power tool. It is possible that it is a same power tool as in the base case 1 or a different one.

Durch das Herstellen eines solchen Sets aus mehreren Transportkoffern 1, 1a, 1b, 1c und einem einzigen Ladekoffer 4 ist es möglich, auf sehr engem Raum eine Vielzahl von akkubetriebenen Elektrowerkzeugen gleichzeitig zu laden. Außerdem ist es möglich, dass sich der Käufer die Elektrowerkzeuge zusammenstellt, die er persönlich benötigt und nicht ein vorgegebenes Kombo-Kit kaufen muss. Durch die individuelle Zusammenstellung der Elektrowerkzeuge kann der Käufer Geld sparen. Außerdem wird dadurch vermieden, dass ein Käufer ständig einen großen Transportkoffer mit einer Vielzahl von Elektrowerkzeugen mit sich tragen muss, wenn er doch nur ein spezifisches Elektrowerkzeug benötigt. Außerdem kann für kurze Einsätze auch auf die Mitnahme des Ladekoffers 4 verzichtet werden, was eine enorme Erleichterung darstellt, da der Ladekoffer 4 sehr schwer ist.By manufacturing such a set of a plurality of carrying cases 1, 1a, 1b, 1c and a single loading case 4, it is possible to load a plurality of battery-powered power tools simultaneously in a very small space. In addition, it is possible for the buyer to put together the power tools that he personally needs and does not have to buy a given combo kit. By the individual composition of the power tools the buyer can save money. In addition, this avoids that a buyer must constantly carry a large carrying case with a variety of power tools when he only needs a specific power tool. In addition, can be dispensed with the entrainment of the loading case 4 for short missions, which is an enormous relief, since the charging case 4 is very heavy.

In Figur 2 ist ein Ausführungsbeispiel für einen in Figur 1 beschriebenen Ladekoffer 4 dargestellt. Dieser weist mehrere Varianten auf, die entweder alle in einem einzigen Ladekoffer 4 verwirklicht werden können oder jede einzelne Variante auch separat in einem gesonderten Ladekoffer 4.In FIG. 2 is an embodiment of an in FIG. 1 described charging case 4. This has several variants, which can either all be realized in a single charging case 4 or each individual variant also separately in a separate charging case. 4

Der Ladekoffer 4 weist in seinem Inneren ein Ladegerät 5 auf. Das Ladegerät 5 ist über ein Netzkabel 6 mit einer externen Stromquelle, beispielsweise einer Steckdose, verbindbar. An einer der Außenflächen des Ladekoffers 4 ist eine zweite Verbindungsvorrichtung 7 mit zweiten elektrischen Kontakten 8 angeordnet. Diese ist mit dem Ladegerät 5 verbunden. Die zweiten elektrischen Kontakte 8 sind im angedockten Zustand, wie zu Figur 1 oben beschrieben, mit den ersten elektrischen Kontakten 3 des Basiskoffers 1 im elektrischen Kontakt. Als Variante weist der Ladekoffer 4 eine weitere zweite Verbindungsvorrichtung 7a auf, die an einer weiteren Außenfläche des Ladekoffers 4 angeordnet ist, die der zweiten Verbindungsvorrichtung 7 entgegengesetzt liegt. Dadurch ist es möglich, einen weiteren Basiskoffer 1 direkt am Ladekoffer 4 anzuschließen. Damit kann eine noch größere Anzahl von Elektrowerkzeugen gleichzeitig durch den Ladekoffer 4 geladen werden.The charging case 4 has in its interior a charger 5. The charger 5 is connected via a power cord 6 with an external power source, such as a power outlet, connectable. On one of the outer surfaces of the charging case 4, a second connecting device 7 with second electrical contacts 8 is arranged. This is connected to the charger 5. The second electrical contacts 8 are in the docked state, as to FIG. 1 described above, with the first electrical contacts 3 of the base case 1 in electrical contact. As a variant, the charging case 4 has a further second connecting device 7a, which is arranged on a further outer surface of the charging case 4, which is opposite to the second connecting device 7. This makes it possible to connect another base case 1 directly to the charging case 4. Thus, an even larger number of power tools can be loaded simultaneously by the charging case 4.

Das Netzkabel 6 ist so ausgebildet, dass es gegen eine Kraft, in der Regel eine Federkraft, wieder in den Ladekoffer 4 hineingezogen wird, wenn es sich nicht in einer Steckdose oder einer sonstigen Stromquelle befindet. Dies ist einem System vergleichbar, das von Staubsaugern her bekannt ist. Es handelt sich um eine automatische Aufrollvorrichtung. Als Variante ist ein weiteres Netzkabel 6a gestrichelt dargestellt, das auf den Ladekoffer 4 von Hand aufgewickelt werden muss. Auch dieses weitere Netzkabel 6a ist natürlich mit dem Ladegerät 5 verbunden und versorgt dieses mit Strom.The power cord 6 is designed so that it against a force, usually a spring force, back into the charging case 4 is pulled in if it is not in a socket or other power source. This is comparable to a system known from vacuum cleaners. It is an automatic retractor. As a variant, another power cord 6 a is shown in dashed lines, which must be wound onto the charging case 4 by hand. This further power cable 6a is of course connected to the charger 5 and supplies it with power.

Als weitere Variante kann der Ladekoffer 4 eine oder mehrere Ladebuchten für einen Ersatzakku-Pack 9 bzw. weitere Ersatzakku-Packs 9a aufweisen. Damit kann gleichzeitig mit dem Aufladen von Elektrowerkzeugen das Auflagen von Ersatzakku-Packs 9, 9a erfolgen. Somit ist es möglich, das Elektrowerkzeug, nach dem dessen Akku-Pack leer ist, mit dem Ersatzakku-Pack 9 bzw. weiteren Ersatzakku-Packs 9a über einen bedeutend längeren Zeitraum netzunabhängig zu betreiben.As a further variant, the charging case 4 may have one or more charging bays for a replacement battery pack 9 or further replacement battery packs 9a. This can be done simultaneously with the charging of power tools, the pads of spare battery packs 9, 9a. Thus, it is possible to operate the power tool, after the battery pack is empty, with the replacement battery pack 9 or other spare battery packs 9a over a significantly longer period off-grid.
