PATENTAMT.PATENT OFFICE.
In vielen Fällen, in denen Apparatenteile an Isolatoren befestigt werden, ist es erforderlich, die Befestigungsschraube dieser Teile verschieben zu können, besonders wenn1 ein Isolator auf einer Steinschraube oder einem Eisendübel sitzt, da das Einsetzen der letzteren in das Mauerwerk nicht genügend genau geschehen kann. Wo es dagegen möglich ist, verwendet man Isolatoren mit feststehenderIn many cases in which parts of the apparatus are attached to insulators, it is necessary to be able to move the fastening screw of these parts, especially when 1 an insulator sits on a stone screw or an iron dowel, since the latter cannot be inserted into the masonry with sufficient precision . Wherever possible, however, insulators with a fixed one are used
ίο Schraube, da dieselben eine sicherere Befestigung gewährleisten.ίο screw, as the same is a more secure attachment guarantee.
Die Erfindung betrifft einen Isolator, bei dem die zur Befestigung der Apparatenteile dienende Schraube von einer Mutter gehalten wird, die in an sich bekannter Weise so ausgebildet ist, daß sie eine glatte und eine mit einem oder mehreren Ansätzen versehene Stirnfläche hat, wobei die Anordnung so getroffen ist, daß die Schraube, je nach der Benutzung der Mutter auf der einen oder der anderen Seite, entweder verschiebbar oder selbsttätig zentriert und festgehalten wird.The invention relates to an insulator, in which the for fastening the apparatus parts serving screw is held by a nut which is designed in a manner known per se is that it has a smooth face and one with one or more lugs has, the arrangement being such that the screw, depending on the use the mother on one side or the other, either movable or automatic is centered and held.
Fig. ι und 2 zeigen eine Ausführungsform der Erfindung im Schnitt.Fig. Ι and 2 show an embodiment of the invention in section.
Ist die Mutter m gemäß Fig. 1 so in die Bohrung u eingeführt, daß ihre glatte Seite nach oben steht, so kann die den Apparatenteil α haltende Schraube s nach allen Seiten verschoben werden, da die Bohrungen 0 und u hierfür entsprechend groß gehalten sind. Wendet man dagegen die Mutter m, so daß ihr Ansatz η nach oben kommt (Fig. 2), so zieht sich letzterer beim Anschrauben des Apparatenteils α nach oben in die Bohrung 0, wodurch die Schraube s selbsttätig in Rollenmitte kommt und dort unverschiebbar festgehalten wird.If the nut m is inserted into the bore u according to FIG. 1 so that its smooth side is upward, the screw s holding the apparatus part α can be displaced in all directions, since the bores 0 and u are kept correspondingly large for this purpose. If, on the other hand, the nut m is turned so that its approach η comes up (Fig. 2), the latter pulls up into the hole 0 when the apparatus part α is screwed on, whereby the screw s automatically comes to the center of the roller and is held there immovably .
Die Erfindung vereinigt die Vorteile der Isolatoren mit verschiebbarer und solcher mit feststehender Apparatenschraube, vereinfacht die Lagerhaltung und erübrigt die aus eingangs erwähnten Gründen häufig notwendige Auswechselung.The invention combines the advantages of the isolators with sliding and such with fixed apparatus screw, simplifies storage and eliminates the need for from the beginning Often necessary substitutions for the reasons mentioned.
