Description

Zündkerzenschlüssel zum Peatschrauben oder Lösen von Zündkerzen an AutomotorenSpark plug wrench for peat screwing or loosening of spark plugs on car engines

Erfindungsgegenstand ist ein Zündkerzenschlüssel zum Festschrauben oder Lösen von Zündkerzen an Automotoren. Die Platzverhältnisse zwischen Motor und Karosseriewand sind oft so beengt, daß kaum eine Bewegungsfreiheit für die Drehung des Hebelarmes vorhanden ist. Außerdem sind die Zündkerzen so tief im Motorblock angeordnet, daß der Schlüssel fast in seiner ganzen Länge in den Motorblock eingeführt wird. Sowohl bei der Drehbewegung als auch beim Festziehen des Schlüssels ergeben sich große Schwierigkeiten. Mit den bisher bekannten Zündkerzenschlüsseln lassen sich in solchen Fällen die Kerzen nicht auswechseln.The subject of the invention is a spark plug wrench for tightening or loosening spark plugs on car engines. The space between the engine and the body wall is often so cramped that there is hardly any freedom of movement for the rotation of the lever arm. Plus, the spark plugs are so deep in the engine block arranged that the key is inserted almost in its entire length into the engine block. Both with the rotary movement and great difficulty arises when tightening the key. With the previously known spark plug wrenches, such Cases do not change the candles.

Für solche Fälle wurde durch die nachstehend beschriebene Erfindung ein Schlüssel geschaffen, der sich in vorteilhafter Weise von den bisher bekannten Arten unterscheidet und einen technischen Fortschritt darstellt. In beigefügter Zeichnung wiri ein RohrsteckschlÜBsel gezeigt, der am unteren Ende ein Innensechskantprofil (1) entsprechend der Zündkerzengröße hat. Am Kopfende ist. ein stark verjüngtes Innenprofil (2) angebracht, das zur Aufnahme des Hebelarmes (3) dient. Als wesentliches Merkmal ist aa Kopfende ein überstellender Ring (4) fest mit dem Schlüssel verbunden. Derselbe kann aus Meteil oder Kunststoff sein. Der Ein,·- LbX am Außenrand griffig.

In the attached drawing, a tubular socket wrench is shown, which has a hexagon socket profile (1) corresponding to the spark plug size at the lower end. At the head end is. a strongly tapered inner profile (2) is attached, which serves to accommodate the lever arm (3). As an essential feature aa head end is a transferring ring (4) firmly connected to the key. The same can be made of metal or plastic. The Ein, · - LbX with good grip on the outer edge. Its purpose is to make the rotary movement nm iismd, as far as ee goes. It also makes it easier to pull out the key with the loosened key or as π kh?
