Abstract

The arrangement protects users of hand tools against shocks caused by inadvertent piercing of hidden electrical wiring, for example when drilling, or hammering fasteners, into walls. A plug (1) is provided with a socket inlet to the neutral pole and an indicator lamp on the live pole so that when correctly inserted to a mains socket the lamp lights. This ensures correct polarity on the plug. A lead (4) connects into the socket inlet and joins it tot he earthing handle (3) on the appliance. If this is a drill further sliding contacts (2) with a lead (6) make additional contact with the spindle. If a live cable is pierced the fault current flows harmlessly to the neutral supply pole instead of to earth through the operator.

Description

B e s c h r e i b Titel: Anti-Elektroschock Ausstaitung. B e s c h r e i b Title: Anti-electric shock equipment.

Anwendungs- Die Erfindung betrifft eine Anti-Elektroschock gebiet: Ausstatung für Bohrmaschinen und Greifzangen.Application The invention relates to an anti-electric shock area: Equipment for drills and grippers.

Insbesonders geeignet fur Handwerker und Heimwerke Zweck: Zum venleiden tödlicher Unfälle durch Stromschlag beim Beschedigen von nichtsichtbaren unter Putz liegenden ei. Leitungen. Ob beim bohren von Löchern für Dübel, oder beim einschlagen von Nägel. Particularly suitable for craftsmen and DIY enthusiasts. Purpose: To suffer fatal accidents due to electric shock when damaging invisible concealed areas lying egg. Cables. Whether drilling holes for dowels or hammering in of nails.

Stand der Bei Beschedigungen unter Putz liegenden el. Lei-Technik: tungen verläuft der tödliche Stromschlag über den menschlichen Körper zur Erde.State of the el. Lei technology lying under plaster in the event of damage: fatal electric shock passes through the human body to earth.

Kritik des Fast 100 Bundesbürger sterben jährlich vom Strom-Standes der schlag getroffen. Gibt es dagegen keinen Schutz? Technik: Hans Furmann, Bundesgescheftsführer der Aktion "Das saubere Haus". (TZ, Jahrgang 1975, 3/4 Mai, Seite 14, "Unterm Putz lauert der Stromtod").Criticism of almost 100 German citizens die every year from the electricity stand hit the blow. Is there no protection against this? Technology: Hans Furmann, Federal Managing Director the "Clean House" campaign. (TZ, year 1975, 3/4 May, page 14, "Unterm Putz electricity death lurks ").

Aufgabe Der Erfindung liegt die Aufgabe zugrunde bei Beschedigung unter Putz liegenden Leitungen. Durch selbststendiger Ausschaltung der Stromzuleitung die Vielzahl der tödlichen Unfälle zu vermeiden und die Sicherheit gegen Stromschlag bei derartigen Arbeten zu gewähren.Problem The invention is based on the problem of damage pipes lying under plaster. By automatically switching off the power supply avoiding the multitude of fatal accidents and providing safety against electric shock to grant in such work.

Lösung: Diese Aufgube wird erfindungsmässig dadurch gelöst, die größte technische Stromrichtung verläuft von Plus nach Minus über den niedrigsten Wiederstand.Solution: According to the invention, this problem is solved by the largest one technical direction of current runs from plus to minus via the lowest resistance.

Durch die Konstruktion der Anti-Elektro schock Ausstatung verläuft der tödliche Stromschlag (nicht wie üblich über den menschlichen Körper zur Erde), sondern über einen Stromabnehmer Nur.2 durch das Verbindungskabel Nr.4 zum Stecker mit Kontrollicht Nr.l zu den negativen Pol der el, Instalation. Durch die Verbindung wischen einen positiven und einen negativen Pol entsteht in diesen kritischen Moment für den Menschen eine erwünschte Unterbrechung der Stromzuleitung. Through the construction of the anti-electric shock equipment runs the fatal electric shock (not as usual on the human body to the Earth), but via a pantograph Nur.2 through the connecting cable no.4 to the Plug with control light no.l to the negative pole of the el, instalation. Through the Connection wipe a positive and a negative pole arises in this critical one Moment for humans a desired interruption of the power supply.

Erzielbare Die mit der Erfindung erzielten Vorteile bestehen Vorteile: insbesonders darin, daß der Mensch bei Beschedigung von unter Putz liegenden el. Leitungen vor tödlichen Unfällen durch Stromschlag geschützt ist.Achievable The advantages achieved with the invention are advantages: especially in the fact that the person with damage to the plastered el. Cables are protected against fatal accidents caused by electric shock.

Die Anti-Elektroschock Ausstatung ist auch herstellerisch kein Problem und sie ist von jedermann sehr leicht zu bedienen. The anti-electric shock equipment is also no problem in terms of manufacturing and it is very easy for anyone to use.
