Description

stativfuß Stativfüße, die aus Profilschienen von U-förmigem Querschnitt bestehen und deren Einzelteile um quer zur Stativfußrichtung verlaufenden Achsen umklappbar und mit seitlichen Feststellmitteln versehen sind, sind bekannt. Bei solchen Stativfüßen «-erden bisher beim Aufklappen derselben in die Strecklage durch die Feststellmittel die Seitenschenkel an den oberen Kanten auseinandergebogen, so daß diese mit der Zeit ihre Federung verlieren, dadurch die Feststellmittel nicht mehr straff ineinandergreifen und der Stativfuß wackelig wird.Stand base Stand base made of profile rails with a U-shaped cross-section exist and their individual parts about axes running transversely to the direction of the base of the tripod are foldable and provided with lateral locking means are known. at such tripod feet «-erden so far when they are unfolded into the extended position the locking means bent the side legs apart at the upper edges, so that they lose their suspension over time, thereby not the locking means interlock more tightly and the tripod base becomes wobbly.

Diese Nachteile werden gemäß der Erfindung dadurch beseitigt, daß der Grundsteg der Profilschiene mit einer längslaufenden, elastischen und als Feder wirkenden Ausbuchtung oder Rille versehen ist, die die mit den Feststellteilen versehenen Seitenschenkel der Profilschienen auseinanderfedern läßt.These disadvantages are eliminated according to the invention in that the base of the profile rail with a longitudinal, elastic and spring acting bulge or groove is provided, which is provided with the locking parts Can spring apart the side legs of the profile rails.

In ihrem äußeren Aussehen entspricht eine solche Rille den bekannten »Sicken«, die bei Profilschienen oder Blechen zur Versteifung bekannt sind. Erfindungsgemäß wird aber diese Rille bei Stativbeinen benutzt und erzielt hier die beabsichtigte Federwirkung für die Feststellmittel.In its external appearance, such a groove corresponds to the known ones »Beads«, which are known for reinforcement in profile rails or sheet metal. According to the invention but this groove is used on tripod legs and achieves the intended one here Spring action for the locking means.

Die Zeichnung zeigt den Erfindungsgegenstand an einem Ausführungsbeispiel, und zwar in Abb. i einen Schnitt in der Längsrichtung des Stativfußes und in Abb. 2 und 3 Querschnitte hierzu.The drawing shows the subject matter of the invention in an exemplary embodiment, namely in Fig. i a section in the longitudinal direction of the stand base and in Fig. 2 and 3 cross-sections for this.

Die aus den Seitenschenkeln i und dem Grundsteg a bestehenden Profilschienen sind in bekannter Weise in mehrere Glieder a, b, c geteilt und je zwei derselben durch einen Drehzapfen 3 miteinander drehbar verbunden, so daß die einzelnen Glieder ineinandergeklappt werden können. An den unteren Enden der Seitenschenkel i sind Körner oder Vorsprünge q. angeordnet, die beim Auseinanderklappen der einzelnen Glieder in an den oberen Enden des benachbarten Gliedes angeordnete Vertiefungen 5 einschnappen und somit den Stativfuß in der Strecklage sichern.The profile rails consisting of the side legs i and the base web a are divided in a known manner into several members a, b, c and two of the same are rotatably connected to one another by a pivot 3 so that the individual members can be folded into one another. At the lower ends of the side legs i there are grains or projections q. arranged which, when the individual links are unfolded, snap into recesses 5 located at the upper ends of the adjacent link and thus secure the stand base in the extended position.

Gemäß der Erfindung ist nun im Grundsteg a eines jeden Gliedes eine elastische, als Feder wirkende Rille 6 eingedrückt. Die federartige Wirkung dieser Rille wird erreicht, wenn das Material eine bestimmte Stärke und Härte nicht überschreitet.According to the invention there is now one in the base a of each link elastic, acting as a spring groove 6 pressed. The feathery effect of this Groove is achieved when the material does not exceed a certain strength and hardness.

Durch diese als Feder wirkende Rille wird nun beim Eindrücken der Körnerpunkte oder Vorsprünge in die Vertiefung das erforderliche Auseinanderdrücken der Seitenschenkel i erreicht.By this acting as a spring groove is now when you press the Punch points or projections in the recess as necessary the side leg i reached.
