Die vorliegende Erfindung bezieht sich insbesondere auf Elektrogeräte, die mit einer Niederspannung (24 V) betrieben werden.The present invention relates in particular to electrical devices that are equipped with a Low voltage (24 V) can be operated.

Gemäß Fig. 1 ist das Elektrogerät eine akkubetriebene Bohrmaschine 10, die mindestens zwei voneinander beabstandete erste Kontaktelemente 12 aufweist, von denen zwei eine unterschiedliche Polarität haben. Referring to FIG. 1, the electrical device is a battery-powered drill 10, the at least two spaced apart first contact elements has 12, two of which have a different polarity.

Die ersten Kontaktelemente 12 sind in der ersten Ausführungsform integriert mit dem Stromkreis der Bohrmaschine 10 verbunden, so daß bei Anlegen einer Spannung an die ersten Kontaktelemente 12 die Bohrmaschine 10 in Betrieb gesetzt wird.In the first embodiment, the first contact elements 12 are integrated with the circuit of the drilling machine 10 , so that the drilling machine 10 is put into operation when a voltage is applied to the first contact elements 12 .

Die ersten Kontaktelemente 12 sind als eine Metallfolie oder als ein Metallgitter ausgebildet und am Außenbereich eines Gehäuses 14 der Bohrmaschine 10 befestigt.The first contact elements 12 are designed as a metal foil or as a metal grid and are attached to the outer region of a housing 14 of the drilling machine 10 .

In einer Modifikation der ersten Ausführungsform ist an einem Schalterknopf 16 ein erstes Kontaktelement 12 befestigt. Für den Fall, daß keine Drehzahlregelung der Bohrmaschine 10 erforderlich ist, kann der Schalter entfallen und der Schalterknopf 16 als feststehendes Teil ausgebildet werden.In a modification of the first embodiment, a first contact element 12 is attached to a switch button 16 . In the event that no speed control of the drill 10 is required, the switch can be omitted and the switch button 16 can be designed as a fixed part.

Wie in Fig. 2 gezeigt ist, hat ein Handschuh 20 mindestens zwei voneinander beabstandete zweite Kontaktelemente 22, von denen zwei eine unterschiedliche Polarität haben. Die zweiten Kontaktelemente 22 sind korrespondierend zu den ersten Kontaktelementen 12 angeordnet, so daß beim Greifen der Bohrmaschine 10 mit dem Handschuhe 20 die ersten Kontaktelemente 12 mit den zweiten Kontaktelementen 22 in elektrischen Kontakt miteinander gebracht werden.As shown in FIG. 2, a glove 20 has at least two spaced apart second contact elements 22 , two of which have a different polarity. The second contact elements 22 are arranged corresponding to the first contact elements 12 , so that when the drill 10 is gripped with the gloves 20, the first contact elements 12 are brought into electrical contact with the second contact elements 22 .

Die zweiten Kontaktelemente 22 sind als eine Metallfolie oder als ein Metallgitter ausgebildet und im Griffbereich des Handschuhs 20 angeordnet.The second contact elements 22 are designed as a metal foil or as a metal grid and are arranged in the grip area of the glove 20 .

Wie in Fig. 3 gezeigt ist, ist eine Stromzuleitung 24 zwischen dem Handschuh 20 und der als Akku 26 ausgebildeten externen Stromquelle angeordnet. Der Akku 26 ist an einem Gürtel 28 befestigt. Dadurch ist der Akku 26 leicht tragbar, und die Stromzuleitung 24 ist vergleichsweise kurz.As shown in FIG. 3, a power supply line 24 is arranged between the glove 20 and the external power source designed as a battery 26 . The battery 26 is attached to a belt 28 . As a result, the battery 26 is easy to carry and the power supply line 24 is comparatively short.

Der Handschuh 26 ist mittels einer Klettverbindung mit dem Gürtel 28 verbindbar.The glove 26 can be connected to the belt 28 by means of a Velcro connection.

Wie in Fig. 1 gezeigt ist, hat in einer modifizierten Ausführungsform die Stromzuleitung 24 mit einem Steckverbinder 30 versehen, der mit einem Gegensteckverbinder am Handschuh 26 oder an der Bohrmaschine 10 verbindbar ist.As shown in FIG. 1, in a modified embodiment the power supply line 24 has a connector 30 which can be connected to a mating connector on the glove 26 or on the drilling machine 10 .

In Fig. 4 ist eine zweite Ausführungsform der Erfindung gezeigt. Ein Adapter 32 hat Adapterkontakte 34, die den Kontakten des Akkus 26 entsprechen und mit Bohrmaschinenkontakten in Verbindung gebracht werden. Adapterleitungen 36 verbinden die Adapterkontakte 34 mit Adapterkontaktelementen 38.In FIG. 4, a second embodiment of the invention is shown. An adapter 32 has adapter contacts 34 which correspond to the contacts of the rechargeable battery 26 and which are connected to drilling machine contacts. Adapter lines 36 connect the adapter contacts 34 to adapter contact elements 38 .

Die Adapterkontaktelemente 38, die den ersten Kontaktelementen 12 der ersten Ausführungsform entsprechen, weisen eine Klebschicht auf, mit der die Adapterkontaktelemente 38 auf das Gehäuse 14 einer Bohrmaschine geklebt werden. Dadurch kann eine herkömmliche Bohrmaschine für die erfindungsgemäße Stromversorgungsvorrichtung verwendet werden.The adapter contact elements 38 , which correspond to the first contact elements 12 of the first embodiment, have an adhesive layer with which the adapter contact elements 38 are glued to the housing 14 of a drilling machine. As a result, a conventional drilling machine can be used for the power supply device according to the invention.

Die Arbeitsweise der Stromversorgungsvorrichtung gemäß den Ausführungsformen wird nachfolgend näher erläutert.The operation of the power supply device according to the embodiments will explained in more detail below.

Der Akku 26 wird an dem Gürtel 28 befestigt. Der Handschuh 20 wird über die Hand der Bedienperson gestreift. Dann wird die Bohrmaschine 10 ergriffen, wobei gleichzeitig die zweiten Kontaktelemente 22 am Handschuh 20 in Kontakt mit den ersten Kontaktelementen 12 der Bohrmaschine 10 bzw. den Adapterkontaktelementen 38 einer herkömmlichen Bohrmaschine gebracht werden. Dadurch erfolgt die Stromzuführung von dem Akku 26 zu der Bohrmaschine 10.The battery 26 is attached to the belt 28 . The glove 20 is slipped over the hand of the operator. The drill 10 is then gripped, the second contact elements 22 on the glove 20 being brought into contact with the first contact elements 12 of the drill 10 or the adapter contact elements 38 of a conventional drill at the same time. This results in the power supply from the battery 26 to the drilling machine 10 .

Da die Bohrmaschine 10 ohne den Akku betrieben wird, ist durch das verringerte Gewicht die Bohrmaschine 10 handlich. Ein weiterer Vorteil besteht darin, daß durch das verringerte Gewicht die Ermüdungserscheinungen durch die Bedienperson gesenkt werden. Beim Loslassen der Bohrmaschine 10 wird gleichzeitig automatisch die Stromzuführung unterbrochen, wodurch die Unfallgefahr verringert wird. Außerdem ist der Einsatz eines stärkeren und damit schwereren Akkus möglich, ohne die Handhabbarkeit der Bohrmaschine einzuschränken.Since the drill 10 is operated without the battery, the reduced weight makes the drill 10 easy to handle. Another advantage is that the reduced weight reduces the fatigue of the operator. When the drill 10 is released, the power supply is automatically interrupted at the same time, thereby reducing the risk of accidents. In addition, the use of a stronger and thus heavier battery is possible without restricting the handling of the drill.

Obwohl die Erfindung in der dargestellten Ausführungsform an Hand einer Bohrmaschine erläutert wurde, kann das Elektrogerät in anderen Ausführungsformen auch eine Schleifmaschine, ein Schwingschleifer, eine Taschenlampe oder eine Profi-Videokamera sein.Although the invention in the illustrated embodiment using a drill has been explained, in other embodiments, the electrical device can also be a Grinding machine, an orbital sander, a flashlight or a professional video camera his.

Mischformen zwischen den einzelnen Ausführungsformen und Modifikationen sind möglich.Mixed forms between the individual embodiments and modifications are possible.
