Abstract

The spanner consists of a core (1) with circumferential toothing working together with two spring loaded pawls (4) in recesses (5) of the spanner head (2). The core has a hexagon-shaped open end with a jaw opening (SW) and is retained within the circular inner surface of the spanner head by a guide rim (3). The two pawls are positioned on the circumference of the toothed core (1) at a spacing which is greater than the jaw opening, so that one set of pawls is always in mesh with the toothing during the ratchet movement. The jaw opening can accept adaptor pieces with external dimensions fitting the jaw dimension and a reduced jaw opening to fit a smaller nut.

Description

Maulschlüsselratsche mitWrench ratchet with

Schlüsselweitenvariationss tücken Die Erfindung betrifft eine Maulschlüsselratsche mit SchlüsselweitenvariaffionsstUcken, die beim Verschrauben jeglicher Sechskantverschraubungen Anwendung findet.Width across flats variation pieces The invention relates to a spanner ratchet with wrench size variance pieces that can be used when screwing any hexagonal screw connections Applies.

Der Aufbau und die Funktionsweise dieser erfindung läßt sich wie folgt beschreiben: Filz 1 Ein Zahnrad (Sperrad) ( in das ein offenes Sechskantprofil eingearbeitet ist, findet in einem Gehäuse (2) mit Hebelarm seine Lagerung. Die Führung des Zahnrads erfolgt durch einen Führungskranz (3), der in das Zahnrad eingearbeitet ist. Im Gehäuse befinden sich zwei Ausspanfungen, die zur Au:fn'ahm der Mitnehmer (4) dienen. Die Mitnehmer snd so angeordnet, daß sie sich mit dem Zahnrad im Eingriff befinden. Von besonderer Bedeutung ist, daß der Abstand zwischen beiden Mitnehmer größer ist als die Schlüsselweite des Schraubenschlüssels. Erreicht das offene Zahnradsegment den ersten Mitnehmer, so ist der zweite Mitnehmer noch im eingriff (und umgekehrt). Eine Abdeckplatte (in Skizze nicht eingezeichnet), die auf den Kopf des Schlüssels geschraubt wird, verhindert ein Verschmutzen des schlüssellnneren und gibt dem Zahnrad auf der offenen Seite die erforderliche Führung.The structure and mode of operation of this invention can be as follows describe: Felt 1 A toothed wheel (ratchet wheel) (in which an open hexagonal profile is incorporated is located in a housing (2) with a lever arm. The leadership of the gear takes place via a guide ring (3) that is incorporated into the gear. in the Housing there are two notches that serve to take the driver (4). The drivers are arranged so that they are in mesh with the gear. It is of particular importance that the distance between the two drivers is greater than the size of the wrench. Reaches the open gear segment the first driver, the second driver is still engaged (and vice versa). A cover plate (not shown in the sketch) on the head of the key is screwed, prevents the inside of the key from getting dirty and gives the gear wheel the required guidance on the open side.

Die handhabung vollzieht sich wie folgt: Durch eine Drehung des Hebelarms in Arbeitsrichtung (siehe Skizze) wird das Zahnrad in Rotation versetzt. It is handled as follows: By turning the lever arm The gear wheel is set in rotation in the working direction (see sketch).

Erfolgt die Drehung des Hebelarms in Leerlaufrichtung (siehe Skizze) werden die Mitnehmer in die Aussparungen (5) gedrückt, und das Zahnrad vollzieht keine Kotationsbewegung. Findet die Ivìaulschlüsselratsche bei Rohrverschraubungen Anwendung, ist nach Beendigung des Verschraubungsvorgangs das Zahnrad (1), nach vorhergegangenem Heraushebens des Schlüssels aus der Verschraubung, unter Zuhilfenahme der auf dem Zahnrad (1) befindlichen Stifte (6), in die Normalstellung (wie in Skizze) zu drehen0 FiF. 2 Die Schlüsselweitenvariationsstücke sind an ihren außeren Körperkanten sechskantförmig ausgebildet L nd ,Vbe- sitzen eine Schlüsselweite (SW), die mit der schlüsselweite (SW) der Maulschlüsselratsche identisch ist, so daß sie zum Zweck der Schlüsselweitenvariation (sw) in die Maulschlsselratsche eingesetzt werden können.If the lever arm is rotated in the idle direction (see sketch), the drivers are pressed into the recesses (5) and the gear wheel does not perform any cotation movement. If the Ivìaul wrench ratchet is used for pipe screw connections, after the screwing process has been completed, the gearwheel (1) is in the normal position (as in the sketch) after the key has been lifted out of the screw connection with the aid of the pins (6) on the gearwheel (1). to rotate 0 FiF. 2 The wrench size variation pieces are hexagonal on their outer body edges L nd , Vbe- sit a wrench size (SW) which is identical to the spanner size (SW) of the wrench ratchet, so that they can be used in the wrench ratchet for the purpose of the wrench size variation (sw).

Die im Zahnrad (1) eingearbeiteten Aussparungen (7) nehmen beim Einsetzen der Schlüsselweitenvariationsstücke die Einsatzhaken (8) auf, und gewährleisten einen festen Sitz der Schlüsselweitenvariationsstücke in der Maulschlüsselratsche. The recesses (7) incorporated in the gearwheel (1) take away when inserted of the wrench size variation pieces on the insert hooks (8), and ensure a tight fit of the wrench size variation pieces in the wrench ratchet.

Der Erfindung liegt folgende Aufgabenstellung zu,grunde: Sie soll eine Aggregation zweier Werkzeuge - dem Maulschlüssel und der Ratsche ("Knarre") - darstellen. Die Nutzung dieser Erfindung besteht auf Grund der oben genannten Aufgabenstellung darin, daß unter Berücksichtigung einer Arbeitserleichterung der universelle einsatz eines Werkzeugs erreicht wird.The invention is based on the following task: you should an aggregation of two tools - the spanner and the ratchet ("ratchet") - represent. The utility of this invention is based on the above The task is that taking into account a work relief of the universal use of a tool is achieved.
