Marita Hilberg-Döringer Maulschlüssel Blatt Nr. 2Marita Hilberg-Döringer open-end wrench sheet no. 2 BeschreibungDescription

Maulschlüssel für Sechskantschrauben und -muttern.Open-end wrench for hexagon screws and nuts.

Zur Montage von Sechskantschrauben bzw. -muttern werden allgemein Umschaltknarren mit verschiedenen Steckschlüsseleinsätzen verwendet, Wo dies wegen Platzmangel bzw. wegen langer Gewindebolzen nicht möglich ist werden meist Maulschlüssel verwendet. Diese haben jedoch gegenüber den Umschaltknarren den Nachteil, daß sie nach einer meist nur kurzen Drehbewegung von dem Verbindungselement abgezogen und neu angesetzt werden müssen. Bei sich häufig wiederholdender Montagetätigkeiten ergeben sich gegenüber der Anwendung von Umschaltknarren erhebliche Zeitverluste.To assemble hexagon screws or nuts, reversible ratchets with various socket wrench inserts are generally used. Where this is not possible due to a lack of space or long threaded bolts, open-end wrenches are usually used. However, these have the disadvantage compared to reversible ratchets that they have to be removed from the connecting element and reattached after a mostly short turning movement. In the case of frequently repeated assembly tasks, this results in considerable time losses compared to the use of reversible ratchets.

Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde einen Maulschlüssel so zu gestalten, daß er ähnlich einer Umschaltknarre gehandhabt werden kann.The invention specified in the protection claim is based on the problem of designing an open-end wrench in such a way that it can be handled in a similar way to a reversible ratchet.

Mit der Erfindung wird erreicht, daß bei Montagearbeiten bei denen wegen der räumlichen Verhältnisse nicht mit einer Umschaltknarre gearbeitet werden kann jetzt eine ähnliche Arbeitsweise und somit Zeitersparnis möglich ist. Zusätzlich wird eine Beschädigung der Kanten (Runddrehen) des Sechskantes vermieden.The invention means that during assembly work where a reversible ratchet cannot be used due to the space available, a similar working method is now possible, thus saving time. In addition, damage to the edges (rounding) of the hexagon is avoided.

Zwei Ausführungsbeispiele der Erfindung werden in der beiliegenden Zeichnung dargestellt.Two embodiments of the invention are shown in the accompanying drawing.

Marita Hilberg-Döringer Maulschlüssel Blattt Nr. 3 Marita Hilberg-Döringer open-end wrench Blattt No. 3

Der Maulschlüssel besteht im wesentlichen aus:The open-end wrench essentially consists of:

A. der Grundplatte (1) in der der Umkreis des Sechskantes ausgespart ist um eine Drehbewegung um den Mittelpunkt zu ermöglichen.A. the base plate (1) in which the circumference of the hexagon is recessed to enable a rotational movement around the center.

B. Hebel (2) oder anderen Elementen (2) die bis zur Schlüsselweite eingreifen und beim Wechsel der Drehrichtung selbsttätig oder durch Handbetätigung über den Umkreis hinaus wegschwenken und somit ein Zurückdrehen ermöglichen.B. levers (2) or other elements (2) which engage up to the wrench width and swing away beyond the circumference automatically or by manual operation when the direction of rotation changes, thus enabling the device to be turned back.

Marita Hilberg-Döringer Maulschlüssel Blatt Nr . 1Marita Hilberg-Döringer open-end wrench sheet no. 1 SchutzansprücheProtection claims Maulschlüssel für Sechskantschrauben und -muttern dadurch gekennzeichnet, daß in der Grundplatte (1) der Umkreis des Sechskantes ausgespart ist und Hebel (2) oder andere Elemente bis zur Schlüsselweite eingreifen können um den Sechskant zu betätigen. Beim Wechsel der Drehrichtung schwenken vorgenannte Elemente wieder über den Durchmesser des Umkreises zurück um eine ungehinderte Drehbewegung zu ermöglichen .Open-end wrench for hexagon bolts and nuts, characterized in that the circumference of the hexagon is recessed in the base plate (1) and levers (2) or other elements can engage up to the wrench size in order to operate the hexagon. When changing the direction of rotation, the aforementioned elements swing back over the diameter of the circumference to enable unhindered rotation.
