Description

Energieversorgung eines elektrischen HandgerätsPower supply for an electrical handheld device

Stand der TechnikState of the art

Die Erfindung geht aus von einer Energieversorgung für insbesondere als Handgerät ausgebildete Werkzeugmaschinen odgl. niederer elektrischer Spannung (6, 12, 24, 48 V) nach der Gattung des Hauptanspruchs.The invention is based on an energy supply for machine tools or the like, in particular as a hand-held device. low electrical voltage (6, 12, 24, 48 V) according to the preamble of the main claim.

Bei einer bekannten gattungsgemäßen Energieversorgung eines elektrischen Handgeräts (DE-OS 43 01 508) wird eine elektrische Handbohrmaschine über deren Kabel und einen Stecker am Anfang des Kabels von einem Akkumulator her mit elektrischer Energie versorgt. Dieser Akkumulator wird über einen Gurtträger vom Benutzer mitgetragen. Außerdem ist an dem Akkumulator ein Wechselrichter vorgesehen, um die Akkumulatorspannung zu transformieren und impuliseren, um dadurch marktübliche 220 V Bohrmaschinen mit dann Wechselstrom versorgen zu können. Als Vorteil wird angegeben, daß das hohe Gewicht und die geringe Kapazität von sogenannten Akku-Maschinen, bei denen der Akku meist im Handgriff des Gerätes untergebracht ist und meist wieder aufladbar ist, zum einen für den Nutzer entsprechenden Nachteilen führt, die durch die Verlagerung des Akkumulators an die Person vermieden werden. Außerdem können handelsübliche "220 V-Maschinen" benutzt werden. Tatsächlich jedoch ist ein solcher Wechselrichter nicht nur aufwendig und mit Eigengewicht verbunden, sondern es ist die mehrfache Stromwandelung mit erheblichen energetischen Verlusten verbunden. Es muß nämlich zuerst der Akkumulator über einen Transformator und Gleichrichter vom Netz her geladen werden, um dann danach die Gleichspannung des Akkumulators über einen Wechselrichter wieder zu Wechselspannung zu wandeln und entsprechend auf 220 V hochzutransformieren. Zudem sind für viele spezielle Einsätze ohnehin "Akku-Maschinen" vorhanden, die dann hier nicht mehr einsetzbar sind.In a known generic power supply for an electrical hand-held device (DE-OS 43 01 508), an electric hand drill is supplied with electrical energy by an accumulator via its cable and a plug at the beginning of the cable. This accumulator is carried by the user via a belt carrier. In addition, an inverter is provided on the accumulator in order to transform and impulse the accumulator voltage, in order to be able to supply 220 V drilling machines with then alternating current. As an advantage, it is stated that the high weight and the low capacity of so-called cordless machines, in which the battery is usually housed in the handle of the device and is mostly rechargeable, leads to corresponding disadvantages for the user, which are caused by the shifting of the Accumulator to the person can be avoided. Commercial "220 V machines" can also be used. In fact, however, such an inverter is not only complex and has its own weight, but multiple power conversion is associated with considerable energy losses. The accumulator must first be charged from the mains via a transformer and rectifier, in order to then convert the direct voltage of the battery to alternating voltage again via an inverter and to transform it up to 220 V accordingly. In addition, there are "cordless machines" available for many special applications, which can then no longer be used.

Die Erfindung und ihre VorteileThe invention and its advantages

Die erfindungsgemäße Energieversorgung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß in sehr einfacher Art die bei den "Akku-Maschinen" vorhandenen Akkumulatoren die über Steckverbindungen an den Geräten angeordnet sind, durch die erfindungsgemäßen Adapter ausgetauscht werden, deren Kabel dann zu dem zentralen Akkumulator führen. Auf diese Weise können auch mehrere Maschinen gleichzeitig von einem solchen Akkumulator mit Strom versorgt werden, wobei entsprechend mehrere parallele Steckdosen am Akkumulator vorhanden sein können. Der Adapter wird erfindungsgemäß in den Aufnahmeraum das normalerweise den Geräteakkumulator aufnimmt, meist eingesteckt, um so die Weiterleitung des Stroms vom zentralen Akkumulator zur elektrischen Maschine zu gewährleisten. Der Adapter kann jedoch auch ein Zwischenteil aufweisen, welches ermöglicht, daß ein generell ausgebildeter Adapter an die nicht genormten Aufnahmeräume appliziert werden kann.The energy supply according to the invention with the characterizing features of the main claim has the advantage that the accumulators present in the "cordless machines", which are arranged via plug connections on the devices, can be replaced by the adapters according to the invention in a very simple manner, the cables of which are then connected to the lead central accumulator. In this way, several machines can be supplied with power from such an accumulator at the same time, it being possible for there to be a plurality of parallel sockets on the accumulator. According to the invention, the adapter is usually plugged into the receiving space that normally receives the device accumulator in order to ensure that the current is passed on from the central accumulator to the electrical machine. However, the adapter can also have an intermediate part, which enables a generally trained adapter to be applied to the non-standard receiving spaces.

Nach einer vorteilhaften Ausgestaltung der Erfindung ist der Akkumulator mit einem an der Person anordenbaren Trägerelement verbunden und wird von der Person in bekannter Weise getragen. Die Person muß dann zwar den Akkumulator tragen, aber nicht zusätzlich noch einen Wechselrichter. Nach einer diesbezüglichen vorteilhaften Ausgestaltung der Erfindung dient als Trägerelement ein Gürtel, Rucksack, eine Tragtrasche odgl. Jedenfalls ist maßgebend, daß die benutzende Person des Gerätes in ihrer Bewegungsfreiheit möglichst wenig beeinträchtigt ist, wobei es eine bekannte Tatsache ist, daß eine Last am leichtesten direkt am Körper zu tragen ist.According to an advantageous embodiment of the invention, the accumulator is connected to a support element which can be arranged on the person and is carried by the person in a known manner. The person must then carry the accumulator, but not additionally an inverter. According to an advantageous embodiment of the invention in this regard, a belt, backpack, carrying bag or the like serves as the carrier element. In any case, it is decisive that the person using the device is impaired as little as possible in their freedom of movement, it being a known fact that a load is easiest to carry directly on the body.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist das Ladegerät zum Akkumulator hin eine Steckverbindung auf mit einem Mutterstück, welches geeignet ist zur Aufnahme des Vaterstücks des Adapterkabels. Hierdurch kann erforderlichenfalls das elektrisch angetriebene Handgerät auch unmittelbar über das Ladegerät mit Energie versorgt werden. Dies kann in manchen Fällen von Vorteil sein, wenn ohnehin ein ortsfestes elektrisches Netz mit 220 V Spannung in der Nähe der Arbeitsstätte zur Verfügung steht.According to a further advantageous embodiment of the invention, the charger has a plug connection to the accumulator with a nut piece which is suitable for receiving the father piece of the adapter cable. As a result, if necessary, the electrically powered hand-held device can also be supplied with energy directly via the charger. This can be an advantage in some cases if a fixed electrical network with 220 V voltage is available near the work site.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Adapter ein Zusatzgerät mit elektrischen Klemmen für die Aufladung einer Kfz-Batterie auf, wobei diese elektrischen Klemmen an ausreichend langen Kabelstücken angeordnet sind und wobei zur Aufladung der Kfz-Batterie die Ladung des am Körper getragenen Akkumulators verwendet wird.According to a further advantageous embodiment of the invention, the adapter has an additional device with electrical terminals for charging a motor vehicle battery, these electrical terminals being arranged on sufficiently long cable pieces and using the charge of the battery worn on the body for charging the motor vehicle battery becomes.

Weitere Vorteile und vorteilhafte Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung, der Zeichnung und den Ansprüchen entnehmbar.Further advantages and advantageous embodiments of the invention can be found in the following description, the drawing and the claims.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Wie in Figur 1 dargestellt trägt eine Person 1 an einem Gürtel 2 einen Akkumulator 3, der über eine Kabel 4 mit einer Stichsäge 5 verbunden ist, wobei an dem der Stichsäge 5 abgewandten Ende des Kabels 4 ein Niederspannungsnormstecker 6 vorhanden ist, der in einen entsprechende Akkumulator 3 vorhandene Steckdose gesteckt ist. Oberhalb dieser Steckdose ist eine zusätzliche Steckdose 7 vorhanden. In diese Steckdose 7 oder aber anstatt des Normsteckers 6 können Normstecker 8 oder 9 gesteckt werden, die zu anderen elektrischen Niederspannungsgeräten gehören, nämlich einem Sägegerät 11 bzw. einer Bohrmaschine 12. Bei den elektrischen Handgeräten 5, 11 und 12 handelt es sich um Niederspannungsgeräte, die j eweil s nich t darge s tellte Aufnahmeräume für wiederaufladbare Akkumulatoren aufweisen. In diese Aufnahmeräume sind am Ende des Kabels 4 angeordnete Adapter vorgesehen, die für die elektrische Stromversorgng von Akkumulator 3 zur elektrischen Maschine dienen.As shown in Figure 1, a person 1 carries on a belt 2 an accumulator 3, which is connected via a cable 4 to a jigsaw 5, a low-voltage standard plug 6 being present at the end of the cable 4 facing away from the jigsaw 5, which plugs into a corresponding one Accumulator 3 existing socket is inserted. An additional socket 7 is provided above this socket. In this socket 7 or instead of the standard plug 6, standard plugs 8 or 9 can be inserted that belong to other electrical low-voltage devices, namely a saw 11 or a drilling machine 12. The electrical hand-held devices 5, 11 and 12 are low-voltage devices, which do not have any illustrated storage spaces for rechargeable batteries. In these receiving spaces at the end of the cable 4 arranged adapters are provided, which are used for the electrical power supply from the accumulator 3 to the electrical machine.

In Figur 2 ist ein Ladegerät 13 in der Außenansicht dargestellt, welches einen Transformator und einen Gleichrichter aufweist und mit seinem Steckerteil 14 in eine Netzsteckdose für 220 V gesteckt ist. In dieses Ladegerät 13 ist ein Normstecker 16 für Niederspannung eingesteckt, dessen Kabel 17 zu dem Akkumulator 3 führt und dort ebenfalls über einen Normstecker 18 verbunden ist. Dieser Akkumulator 3 ist, wie in Figur 1 gezeigt, am Gürtel 2 anordbar. Wie Figur 2 entnehmbar ist, kann der Normstecker 6 des Kabels 4 bzw. der Stichsäge 5 oder auch die Normstecker 8 und 9 der anderen Geräte 1 1 und 12 in diese am Ladegerät 13 vorhandene Steckdose anstatt des Normsteckers 16 oder parallel zu diesem eingesteckt werden, um dadurch in manchen praktischen Fällen direkt vom Netz aus über das Ladegerät mit Strom versorgt zu werden. Die erfindungsgemäße Energieversorgung weist somit ein Kabel 4 auf mit einerseits einem Stecker 6, 16 und andererseits einem Adapter, der in den "Batterieraum" für übliche Akku-Handgeräte einsetzbar ist.In Figure 2, a charger 13 is shown in the external view, which has a transformer and a rectifier and is plugged with its plug part 14 into a 220 V mains socket. A standard plug 16 for low voltage is inserted into this charger 13, its cable 17 leads to the accumulator 3 and is also connected there via a standard plug 18. As shown in FIG. 1, this accumulator 3 can be arranged on the belt 2. As can be seen in FIG. 2, the standard plug 6 of the cable 4 or the jigsaw 5 or the standard plug 8 and 9 of the others Devices 1 1 and 12 can be plugged into this socket on the charger 13 instead of the standard plug 16 or parallel to it, in order to be supplied with power in some practical cases directly from the mains via the charger. The energy supply according to the invention thus has a cable 4 with on the one hand a plug 6, 16 and on the other hand an adapter which can be used in the "battery compartment" for conventional cordless handheld devices.
