Description

Die Erfindung betrifft ein Zwischenstück zum Verbinden und Verlängern von Schraubenschlüsseln.The invention relates to an intermediate piece for connecting and Extend wrenches.

Mitunter ist es erforderlich, einen Schraubenschlüssel zu verlängern, weil dessen Hebelarm in der Länge nicht ausreicht. Hierzu wird meist ein Rohr auf den Schraubenschlüssel aufgeschoben. Meist ist jedoch im Bedarfsfall ein entsprechendes Rohr nicht vorhanden. Dieses ist außerdem sehr raumfordernd. Die Verbindung zwischen dem Rohr und dem Schraubenschlüssel ist ferner mechanisch sehr instabil.Sometimes it is necessary to use a wrench extend because its lever arm is not long enough. To do this, a pipe is usually placed on the wrench postponed. Most, however, is when needed a corresponding pipe is not available. This is as well very space-consuming. The connection between the pipe and the wrench is also mechanically very unstable.

Die DE 3416276 A1 beschreibt ein Zwischenstück zum Kombinieren von zwei Schraubenschlüsseln. Zwei oder mehrere Sechskant-Platten, von denen jede einer anderen Schlüsselweite entspricht, sind dort in kleiner werdender Reihenfolge über der größten Sechskant-Platte übereinanderliegend vorgesehen. Zur Verhinderung eines seitlichen Abrutschens von angesetzten Gabelschlüsseln sind zwischen den einzelnen Sechskant-Platten sowie unterhalb der größten Sechskant-Platte überkragende Scheiben vorgesehen, deren Durchmesser etwas größer als der Durchmesser der jeweiligen Sechskant-Platte ist.DE 3416276 A1 describes an intermediate piece for combining of two wrenches. Two or more Hexagon plates, each with a different wrench size corresponds, are there in decreasing order overlapping over the largest hexagon plate intended. To prevent slipping sideways of attached wrenches are between the individual hexagon plates as well as below the largest Hexagon plate cantilevered washers provided Diameter slightly larger than the diameter of each Hexagon plate is.

Ein derartiges Zwischenstück weist insbesondere den Nachteil auf, daß es beispielsweise aus der freien Gabel eines eine zu lösende Mutter umfassenden Doppelgabelschlüssels leicht herausrutscht, wenn die Längsachse des Doppelgabelschlüssels ausgelenkt aus der Horizontalen nach unten weist. Such an intermediate piece has the particular disadvantage on that it is, for example, from the free fork of a a double fork wrench to be loosened slips out easily when the longitudinal axis of the double wrench deflected down from the horizontal points.

Ein derartiges Zwischenstück ist ferner insbesondere deswegen nachteilig, weil der an dem Zwischenstück angesetzte zweite Doppelgabelschlüssel leicht von der entsprechenden Sechskant-Platte des Zwischenstücks abrutscht, wenn die Längsachse dieses zweiten Gabelschlüssels etwas nach unten zeigt.
Die beiden soeben angeführten Nachteile machen sich vornehmlich beim Umgreifen störend bemerkbar.Such an intermediate piece is also disadvantageous in particular because the second double wrench attached to the intermediate piece easily slips off the corresponding hexagonal plate of the intermediate piece if the longitudinal axis of this second wrench points somewhat downward.
The two disadvantages just mentioned are particularly noticeable when reaching around.

Die Aufgabe der Erfindung besteht daher in der Bereitstellung eines Zwischenstücks zur Verlängerung und zum Verbinden von Schraubenschlüsseln, welches einen sicheren Zusammenhalt von mindestens zwei Gabelschlüsseln und dem zwischengeschalteten Zwischenstück gewährleistet.The object of the invention is therefore in Provision of an intermediate piece for extension and for connecting wrenches, which one safe cohesion of at least two wrenches and the intermediate one Spacer guaranteed.

Zusätzlich sind erfindungsgemäß an dem Zwischenstück Anschlagelemente ausgebildet, die mit Ihrer Fläche quer zu der Zwischenstückachse stehen und die zusätzlich magnetisch sind.The intermediate piece according to the invention consists of a section of a polygonal profile bar, the invention has the outer profile of a nut. The Edges of the outer profile extend along the intermediate piece axis and are arranged symmetrically to it. In addition, stop elements according to the invention are on the intermediate piece trained that across with your area the intermediate piece axis and which are also magnetic are.

Das Zwischenstück nach der Erfindung bildet ein kurzes Teil, das leicht in der Werkzeugkiste untergebracht werden kann. Durch die erfindungsgemäße Konstruktion des Zwischenstücks wird der Vorteil erzielt, daß zwei Gabelschlüssel zur Verlängerung des Hebelarms aneinanderfügbar sind. In der Ausgestaltung nach Anspruch 3 besteht zwischen den beiden Gabelschlüsseln nur ein geringer Versatz, der sich aus der Dicke des Schraubenschlüssels ergibt.The intermediate piece according to the invention forms a short one Part that can easily be accommodated in the tool box can. The inventive construction of the intermediate piece the advantage is achieved that two wrenches can be joined together to extend the lever arm are. In the embodiment according to claim 3 only a small one between the two wrenches Offset resulting from the thickness of the wrench results.
