Steckschlüssel mit GesperreSocket wrench with lock
Muttern oder Bolzen, die sich an schwer zugänglichen· Stellen "befinden,, können häufig nur unter Schwierigkeiten angezogen oder gelöst werden. Oft ist auch der um die Mutter oder den Schraubenkopf vorhandene Raum zu klein, um einen normalen Schraubenschlüssel zu verwenden.Nuts or bolts in hard-to-reach places "Located, can often only be attracted with difficulty or be resolved. Often he is also around the mother or her Screw head existing space too small for a normal one Use wrench.
Es ist deshalb die Aufgabe der vorliegenden Erfindung, einen Steckschlüssel mit Gesperre vorzuschlagen, mit dessen Hilfe alle von Hand zugänglichen Stellen erreicht werden können.It is therefore the object of the present invention to provide a Socket wrench with locking mechanism to propose with the help of it all places accessible by hand can be reached.
Ein solcher Steckschlüssel besteht aus zwei drehbaren, koaxialen Teilen, die durch einen Sperrmechanismus verbunden sind, wobei das eine Element direkt oder indirekt an das festzuziehende oder zu lösende Teil angreift,-während das andere Element von Hand gedreht wird. Der Steckschlüssel istSuch a socket wrench consists of two rotatable, coaxial parts that are connected by a locking mechanism are, where one element is directly or indirectly linked to the engages to be tightened or loosened part, while the other element is rotated by hand. The socket wrench is

weitherin gekennzeichnet durch die Tatsache, daß das letztgenannte Element ein erhöhtes Trägheitshauptmoment auf v/eist und dadurch eine Schwungscherbe bildet.further characterized by the fact that the latter element is an increased principal moment of inertia on v / e and thereby forms a swing fragment.
Die Erfindung soll nachstehend anhand von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Zeichnungen näher erläutert werden. In den Zeichnungen zeigen:The invention is intended below on the basis of exemplary embodiments with reference to the accompanying drawings are explained in more detail. In the drawings show:
Fig. 1 eine Ansicht;Fig. 1 is a view;
Fig. 2 einen Schnitt entlang der Linie II-II der Fig. 1 jFIG. 2 shows a section along the line II-II of FIG. 1 j
und
Fig. 3 eine teilweise geschnittene Ansiht entsprechend and
Fig. 3 is a partially sectioned view accordingly
der Fig. 1 zur Darstellung eines Zubehörteils.1 to illustrate an accessory.
Der in der Zeichnung dargestellte Steckschlüssel ist bestimmt zur Verwendung mit einer Nuß, die auf der einen Seite ein Vierkantinnen-Angriffselement und auf der anderen Seite ein Vielkant- oder Nuten-Innen-Angriffselement aufweist zur Aufnahme des festzuziehenden oder zu lösenden Schraubenkopfes oder der Mutter.The socket wrench shown in the drawing is intended for use with a nut that is on one side Square female attack element and on the other side Polygon or groove inner attack element has for Recording of the screw head to be tightened or loosened or the mother.
Der Steckschlüssel besteht aus einem Vierkant 10, aus einem Einsatz 11, in dem der Vierkant 10 in zwei axialen Stellungen durch Kugel-Sperrglieder 12 festgehalten werden kann, durch zwei Seitenwände 13, die am Einsatz 11 angebracht sind, durchThe socket wrench consists of a square 10, from one Insert 11, in which the square 10 can be held in two axial positions by ball locking members 12 through two side walls 13 attached to the insert 11 through

einen an seiner Außenseite als Sechskant ausgebildeten Ring 14, der frei auf einer Tragfläche des Einsatzes 11 zwischen den Seitenwänden 13 drehbar ist, durch einen Freilaufmechanismus bestehend aus einer am Einsatz angebrachten Sperrklinke 15 und einem von der Innenwand des Ringes 14 gebildeten Sperrad 16, wobei der Freilaufmechanismus die Umwandlung einer intermittierenden Drehbewegung des Ringes 14 in eine intermittierende Vorschubbewegung des Vierkants 10 gestattet.a ring designed as a hexagon on its outside 14, which is freely on a wing of the insert 11 between the side walls 13 is rotatable by a freewheel mechanism consisting of a pawl attached to the insert 15 and a ratchet wheel 16 formed by the inner wall of the ring 14, the freewheel mechanism doing the conversion an intermittent rotational movement of the ring 14 Allowed in an intermittent feed movement of the square 10.
Der Ring 14 besitzt ein beträchtliches Trägheitsmoment, so daß bei einer Drehung von Hand ein genügend hohes Kraftmoment zur Verfügung steht, um Muttern, Bolzen oder ähnliche Teile bei normalem Anzugsmoment festziehen oder lösen zu können. _ - - , _The ring 14 has a considerable moment of inertia, so that when turned by hand there is a sufficiently high moment of force available to tighten or loosen nuts, bolts or similar parts with normal tightening torque. _ - -, _
Falls notwendig, kann das Festziehen oder Lösen auch mit Hilfe eines Gabelschlüssels, der am Sechskant angreift, erfolgen.If necessary, tightening or loosening can also be done with With the help of an open-ended wrench that engages the hexagon, take place.
Zu dem vorgeschlagenen Steckschlüssel gehört ein Zubehörteil (Fig. 3), bestehend aus einem Aufsatz 17, der über den Sechskant des Einsatzes 11 gestülpt wird, und der selbst einen Sechskant 18 mit kleinem Durchmesser besitzt,The proposed socket wrench includes an accessory (Fig. 3), consisting of an attachment 17, which is slipped over the hexagon of the insert 11, and the itself has a hexagon 18 with a small diameter,

(S(P
Mit Hilfe dieses Zubehörteils, das zur Erhöhung der Griffigkeit an der Außenseite gerändelt sein kann, ist es möglich,With the help of this accessory, which can be knurled on the outside to increase the grip, it is possible to
a) die Trägheit der Anzugsschwungscheibe zu erhöhen, unda) to increase the inertia of the flywheel, and
b) einen Gabelschlüssel mit kleiner Maulweite für das Festziehen und Lösen zu verwenden.b) to use an open-end wrench with a small opening for tightening and loosening.
Der vorgeschlagene Steckschlüssel hat zahlreiche Vorteile, besonders den, daß er überall dort, wo ein Zugang von Hand möglich ist, verwendet werden kann und so einen wertvollen Zeitgewinn beim Lösen und Festziehen von Bolzen, Schrauben usw. gestattet.The proposed socket wrench has numerous advantages, especially that it can be used wherever there is manual access is possible, can be used and thus a valuable gain in time when loosening and tightening bolts and screws etc. permitted.
