Abstract

The invention relates to a portable energy source which is designed as a battery bar and is based predominantly on gas-tight nickel-cadmium or lead batteries. Virtually any voltage and capacity can be produced by means of a plug-in system. In the same way, defective batteries can be replaced, either as relatively small battery units or as individual cells (with the aid of a battery testing and sorting apparatus). The total voltage can be set as desired by plugging basic battery bars together and lengthening them and, if required, a complete range of apparatuses can be operated using a small number of batteries. The energy source is intended for electrical tools and apparatuses having a relatively high power consumption. It allows the batteries to be charged in a protective "normal charging" mode as well as allowing a "rapid charging" mode to be carried out without problems (the contact for PTC or NTC is positioned in the centre of the plug). This plug connects the battery bar either to the apparatus (tool) or charging apparatus, or to other battery bars. The plug having a solar cell as a unit (solar-battery readiness maintenance) guarantees the battery bar is in the full charge state, without any cord, over a relatively long time (the light is converted into electrical current and is supplied to the battery where it compensates for the relatively high self-discharge of the battery). <IMAGE>

Description

B e s c h r e i b u ng Description

s c h r e i Energie-Batteriestab mit Stecksystem, kombinierbar zu jeder Gleichstromspannung, tragbar auf dem Gürtel, als Tasche oder Koffer, bzw. Rucksack Die Basis dieser Energie-Quelle bilden Ni-Cd gasdichte Batterien mit der Nennspannung von 1,2 V / Zelle. s c h r e i Energy battery stick with plug-in system, can be combined with any DC voltage, portable on the belt, as a bag or suitcase, or Backpack Ni-Cd gas-tight batteries with the form the basis of this energy source Nominal voltage of 1.2 V / cell.

In Abbildungen ist von einer Basis-Zelle 1,2 V - 4 Ah ausgegangen worden. A basic cell of 1.2 V - 4 Ah is assumed in the figures been.

Anwendung Gleichstrom-Energie-Quelle für alle tragbare Geräte, Lampen, usw. insbesondere für Elektro-Werkzeuge. Bei diesen Anwendungen ist durch die systembedingten Vorteile der Ni-Cd Batterien ihr Einsatz unentbehrlich geworden. Bei den Elektrowerkzeugen (Schrauber, Handbohrmaschinen, Handbohrhammer, Stichsäge, Schleifer, Klammer-Hammer, Schere, Spritzpistole, usw.) werden die Batterien integriert im Werkzeug eingesetzt. Application of direct current energy source for all portable devices, lamps, etc. especially for electrical tools. In these applications is due to the system-related Advantages of Ni-Cd batteries their use has become indispensable. With the power tools (Screwdrivers, hand drills, hand hammer, jigsaw, grinder, clamp hammer, Scissors, spray gun, etc.), the batteries are integrated into the tool.

Sowohl der Platzbedarf, als auch das Gewicht begrenzen stark die Größe, d. h. die Kapazität der Stromquelle und damit die Betriebszeit des Gerätes. Man ist gezwungen die Batterien im Schnellverfahren wiederaufzuladen. Dadurch wird die Lebensdauer der Batterie bis auf 1/5 reduziert. Der gezogene Strom ist im Verhältnis zu der Batteriekapazität enorm hoch, was zwangsläufig zu Frühausfällen führt. Batterie-Koffer mit einer Batterie graßerer Kapazität würden wieder die Mobilität dieser Werkzeuge zunichte machen. Die ebenfalls auf dem Markt befindlichen Batteriegürtel sind für Serien-Industrieprodukte zu kompliziert und zu teuer. Allein schon die erwähnten Nd-Cd Batterien bedeuten einen großen Kosten-Faktor. Darüber hinaus erlaubt es die Komplettierung der Batterie nicht, z. B. lediglich nur eine defekte Zelle im Batterieverband auszutau- Beschreibung schen, sondern es wird in der Regel die ganze Batterie ersetzt. Bei einer 12 V Batterie mit 10 Zellen bedeutet dies eine Verteuerung um Faktor 10. Both the space requirement and the weight severely limit the Size, d. H. the capacity of the power source and thus the operating time of the device. You are forced to recharge the batteries in a fast process. This will the service life of the battery is reduced to 1/5. The current drawn is in proportion to the battery capacity enormously high, which inevitably leads to early failures. Battery case with a battery of greater capacity, the mobility of these tools would be restored destroy. The battery belts that are also on the market are for Series industrial products too complicated and too expensive. Just the ones mentioned Nd-Cd batteries represent a major cost factor. In addition, it allows the Do not complete the battery, e.g. B. only one defective cell in the battery bank to be exchanged Description but it will usually be the whole Battery replaced. In the case of a 12 V battery with 10 cells, this means that it is more expensive by a factor of 10.

Energie-Batterie-Stab mit Stecksystem bietet folgende Möglichkeiten, Vorteile und Neuigkeiten: 1. Eine einfache, hochbelastbare, mobile Gleiehstromquelle mit mindestens 4 mal größerer Kapazität als es bei den in Elektrowerkzeugen integrierten Batterien der Fall ist.Energy battery stick with plug-in system offers the following options, Advantages and news: 1. A simple, heavy-duty, mobile DC power source with at least 4 times greater capacity than those built into power tools Batteries is the case.

2. Durch einfaches Stecksystem - wobei sich insbesondere die ~2-er Reihe"(Zchg. 1 und 2) und die "4-er Reihe" (Zchg. 4 und 4a), bzw. die Kombination der "4-er und 2-er Reihe" empfiehlt, bzw. durch eine Verlängerung des Batteriestabes (es wird lediglich die entsprechende Rohrlänge eingebaut - s. Zchg. 5) ist praktisch jede nötige Spannung erreichbar. Auf dem Markt befinden sich Elektro-Werkzeuge, die mit verschiedenen Batt.-Spannungen arbeiten - von 4,8 V bis 24 V. Durch das Stecksystem sind alle diese Anwendungen abzudecken. Der besondere Vorteil liegt darin, daß man nicht für jedes Gerät separate Batterie, Koffer oder Batt.-Gürtel braucht, sondern durch das Zusammenstecken von Basis-Batteriestab, Kupplung, bzw. Verlängerung die Gesamtspannung beliebig gestalten kann.2. With a simple plug-in system - whereby in particular the ~ 2-er Row "(Fig. 1 and 2) and the" 4-er series "(Fig. 4 and 4a), or the combination recommends "4 and 2 rows", or by extending the battery rod (only the corresponding pipe length is installed - see drawing 5) is practical every necessary tension achievable. There are power tools on the market, that work with different battery voltages - from 4.8 V to 24 V. Plug-in system must cover all of these applications. The particular advantage lies in the fact that you do not have a separate battery, case or battery belt for each device needs, but by plugging together the basic battery stick, coupling or Extension can make the total voltage arbitrarily.

3. Eine Verlängerung der Batterielebensdauer um mindestens Faktor 4, was insbesondere aus volkswirtschaftlichen Gründen keine unbedeutende Rolle spielt. Dabei ist ein Schnellaufladen des Batteriestabes ohne weiteres möglich, weil das Anbringen eines Thermofühlers problemlos durchführbar ist.3. An extension of the battery life by at least a factor 4, which does not play an insignificant role, especially for economic reasons. Rapid charging of the battery stick is easily possible because that Attaching a thermal sensor can be carried out without any problems.

4. Ein "Parallel-Stecker-Verbinder" (s. Anl. 6) ermöglicht, falls nötig mehrere Batterie-Stäbe zusammenzuschalten, um die Kapazität zu verdoppeln, bzw. zu verdreifachen, usw.4. A "parallel plug connector" (see Appendix 6) enables, if it is necessary to connect several battery bars to double the capacity, or to triple, etc.

Das Wiederaufladen erfolgt dann in der Serie. The recharging then takes place in series.

5. Als Verbindung zwischen dem Batteriestab und dem Gerbt dient ein Universal-Stecker mit einem Spiralkabel (s. Anl. 3).5. A serves as a connection between the battery stick and the Gerbt Universal plug with a spiral cable (see Appendix 3).

6. Falls bei einer hohen Spannung und großer Kapazität das Gewicht erheblich ensteigen würde, kann man mit zusätzlichen Halterungen für eine bessere Gewichtsverteilung sorgen, (s. Anl. 7), bzw. bei mehreren Batt.-Stäben nach Zchg. 7a verfahren.6. In case of high voltage and large capacity, the weight would increase significantly, one can use additional brackets for a better one Ensure weight distribution (see Appendix 7), or in the case of several battery rods according to drawing. 7a procedure.
