Abstract

In a socket spanner, in particular spark plug spanner, having a fixed or interchangeable attachment receptacle which possesses a holding magnet (3) which is installed above its attachment faces and consists of a tubular rubber magnet foil which is longitudinally divided once or more than once and is magnetised in the thickness direction, in accordance with Patent Application P 3142528.3-515, the holding force of the holding magnet is to be increased. For this purpose, provision is made according to the invention for the tubular holding magnet to be provided on its inner wall likewise with a magnetic return plate which preferably consists of a plurality of shell parts (11, 12) which cover the segments (6, 7) of the longitudinally divided rubber magnet foil in each case approximately flush therewith.

Description

Zusatz zu Patentanmeldung P 31 42 528.3-15Addition to patent application P 31 42 528.3-15

Steckschlüssel, insbesondere Zündkerzenschlüssel Die Erfindung betrifft einen Steckschlüssel, insbesondere Zündkerzenschlüssel, mit einer festen oder auswechselbaren Steckhülse, die einen oberhalb ihrer Aufsteckflächen eingebauten Haltemagneten aufweist, der ein oder in Dickenrichtung magnetisierten, rohrförrnigen, ein- oder mehrfach längsgeteilten Gummimagnetfolie besteht gemäß Patentanmeldung P 31 42 528.3-15. Socket wrenches, particularly spark plug wrenches The invention relates to a socket wrench, in particular a spark plug wrench, with a fixed or exchangeable one Receptacle which has a holding magnet installed above its slip-on surfaces, the tubular, single or multiple magnetized or magnetized in the direction of the thickness Longitudinally divided rubber magnetic sheet is made according to patent application P 31 42 528.3-15.

Der Steckschlüsse@ nach der Hauptpatentanmeldung zeichnet sich durch hohe Verschleißfestigkeit und geringe 13cschädigungsgefährdung für loszuschraubende Teile aus.The plug-in connection @ according to the main patent application is characterized by high wear resistance and low risk of damage for those who are unscrewed Share out.

Allerdings hat sich gezeigt, da13 eine Erhöhung der Haltekraft des Haltemagneten wünschenswert ist, was Aufgabe der vorliegenden Erfindung ist.However, it has been shown that an increase in the holding force of the Holding magnets is desirable, which is the object of the present invention.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß der rohrförmige Haltemagnet an seiner Innenwandung ebenfalls mit einem Rückschlußblech versehen ist. Vorzugsweise kann hierbei das Rückschlußblech aus mehreren Mantelteilen bestehen, die die Segmente der längsgeteilten Gummimagnetfolie jeweils etwa bündig überdecken.To solve this problem, the invention provides that the tubular holding magnet on its inner wall also with a return plate is provided. The return plate can preferably consist of several jacket parts exist, the segments of the longitudinally divided rubber magnetic sheet each approximately flush cover.

Durch die nunmehr beidseits der Gummimagnetfolie vorgesehenen Rückschluß bleche wird der magnetische Kraftfluß gebündelt und werden an dem dem Steckschlüsselmaul zugewandten Ende des Haltemagneten kräftige magnetische Nord- und Süd pole geschaffen, an denen das loszuschraubende Teil, z B. der Sockel einer Zündkerze, sicher haftet.Due to the return path that is now provided on both sides of the rubber magnetic sheet sheets, the magnetic flux of force is bundled and attached to the socket wrench facing end of the holding magnet strong magnetic north and south poles created, to which the part to be unscrewed, e.g. the base of a spark plug, securely adheres.

Die Teile des innenliegenden Rückschlußbleches sind auf der Gummimagnetfolie nachgiebig elastisch abgestützt, wodurch die Gefahr einer Beschädigung des loszuschraubenden Teiles niedrig gehalten bleibt Die Erfindung wird irn folgenden anhand der Zeichnung näher erläutert, welche den Kopf eines als Zündkerzenschlüssel ausgebildeten Rohrsteckschlüssels im Längsschnitt zeigt.The parts of the inner return plate are on the rubber magnetic sheet resiliently supported elastically, reducing the risk of damage to the unscrewed Part is kept low The invention is carried out in the following explained in more detail with reference to the drawing, which is the head of a spark plug wrench trained tubular socket wrench shows in longitudinal section.

Der Rohrsteckschlüssel ist an seinem unteren, etwas aufgeweiteten Ende mit Aufsteckflächen 1 versehen und in seinem darüber liegenden, im Durchmesser etwas engeren Teil 2 ist ein rohrförmiger Haltemagnet 3 eingebaut, der beim Ausführungsbeispiel aus zwei halbzylindrischen Mantelteilen 4, 5 besteht. Jeder Mantelteil 4, 5 besteht aus einem Gummimagnetfolie-Segment 6, 7, die in Dickenrichtung magnetisiert sind und an ihrer Außenseite ein Rückschlußblech 8, 9 und an ihrer Innenseite weitere Rückschlußbleche 11, 12 tragen. Die Rückschlußbleche 8, 9 sind an der Innenwandung des Steckschlüsselteiles 2 angeklebt, wobei die Mantelteile 4, 5 nach unten etwas in den erweiterten Teil des Steckschlüssels vorstehen. Die Rückschlußbleche 8, 9 und 11, 12 sird durch Kleben oder Vulkanisieren mit den Segmenten 6, 7 der Gummimagnetfolie verbunden.The tubular socket wrench is slightly widened at its lower part End provided with slip-on surfaces 1 and in its overlying, in diameter somewhat narrower part 2, a tubular holding magnet 3 is installed, which in the embodiment consists of two semi-cylindrical casing parts 4, 5. Each shell part 4, 5 is made from a rubber magnetic film segment 6, 7, which are magnetized in the thickness direction and a return plate 8, 9 on its outside and more on its inside Back yoke plates 11, 12 wear. The return plates 8, 9 are on the inner wall of the socket wrench part 2 glued, the shell parts 4, 5 down slightly protrude into the enlarged part of the socket wrench. The return plates 8, 9 and 11, 12 are glued or vulcanized to the segments 6, 7 of the rubber magnetic sheet tied together.

Der Magnetfluß wird durch die Rückschlußbleche 8, 9 und die inneren Rückschlußbleche 11, 12 zu den Stirnenden des Haltemagneten 3 geleitet, so daß die dort austretenden Feldlinien 10 ein etwis tlJrusf(irrr)igcs, weit in den Aufnahmeraum für die festzuhaltende Mutter oder dgl. hineinragendes Magnetfeld bilden.The magnetic flux is through the return plates 8, 9 and the inner Return plates 11, 12 passed to the front ends of the holding magnet 3, so that the Field lines 10 exiting there a little bit tlJrusf (irrr) igcs, far into the receiving space for the nut to be held or the like. Form a protruding magnetic field.
