Description

Schwenkarm mit Gewichtsausgleichsfeder.Swivel arm with counterbalancing spring.

In modernen Schwenkarmen zum Tragen von Geräten und dergl. ist die Gewichteausgleichafeder im Innern der meist aus Profilrohren bestehenden Tragarme untergebracht. Muß die Spannung der Feder nachgestellt werden, sei es, weil die Feder bei der bisherigen Einstellung nachgelassen hat, sei es, daß andere Ursachen vorliegen, dann konnte dies bisher nur nach Demontage einzelner Bauteile erfolgen. vor allem konnte die Einstellung der Ausgleichskraft nicht unter der normalen durch das von dem Schwenkarm getragene Gerät verursachten Belastung vorgenommen werden.In modern swivel arms for carrying devices and the like. Is the Weight compensation spring inside the support arms, which usually consist of profile tubes housed. Does the tension of the spring have to be readjusted, be it because the Spring has waned in the previous setting, be it for other reasons exist, this could previously only be done after dismantling individual components. above all, the adjustment of the balancing force could not go below normal the load caused by the swivel arm carried device.

Dieser Umstand erschwerte die Nachstellarbeit ungemein, so daß man kleinere vorkommende Abweichungen vom erstrebten Gleichgewicht durch Einbau von Friktionen in die Gelenke des Schwenkarmes auszugleichen suchte, die den Preis solcher Schwenkarme wesentlich erhöhten.This circumstance made the readjustment work extremely difficult, so that one minor deviations from the desired equilibrium due to the incorporation of Tried to compensate for friction in the joints of the swivel arm, which increases the price of such Swivel arms significantly increased.

Diese Nachteile werden durch nachstehend erläuterte Erfindung vor mieden. Die zur Einstellung der Pederkaft dienende Gewindemutter, die vorteilhafterweise als Rundmutter ausgebildet eine grössere Anzahl von Sacklöchern erhält, um sie in bekannter Weise mittels eines Dornschlüssels verdrehen zu können, wird dadurch von außen her zugänglich gemacht, daß das Tragrohr des Schwenkarmes, in dem die Feder mit der Einstel lumutter liegt, über der Einstellmutter eine fensterartige Aussparung erhält, so daß man ohne Demontage 'irgendwelcher Bauteile die Federspannung verändern kann.These disadvantages are overcome by the invention explained below avoided. The threaded nut used to adjust the Pederkaft, which advantageously designed as a round nut receives a larger number of blind holes to put them in to be able to rotate in a known manner by means of a mandrel wrench, is thereby of Made accessible from the outside that the support tube of the swivel arm in which the spring with the adjusting nut, a window-like recess is above the adjusting nut obtained so that you can change the spring tension without dismantling any components can.

In den beigegebenen Zeichnungen ist die Erfindung in einem Ausfüh rungsbeispiel dargestellte Fig. l zeigt einen Längsschnitt durch die Einstellvorrichtung des Schwenkarmes, Fig. 2 zeigt eine Teilansicht in Richtung "C" auf Fig. 1.In the accompanying drawings the invention is in one embodiment Approximate example shown Fig. l shows a longitudinal section through the adjustment device of the swivel arm, FIG. 2 shows a partial view in the direction "C" of FIG. 1.

Die Zugstange 5 der Ausgleichsvorrichtung, die konzentrisch in. dem Tragrohr 4 des Schwenkarmes angeordnet ist, hat ein Gewinde für eine Verstellmutter l, die vorteilhaft als Rundmutter mit mehreren Sacklöchern la zum Ansetzen eines Dornschlüssels versehen ist. ßs kann selbstverständlich auch eine andere Mutterform, z. B. eine Sechskantmutter, verwendet werden. Die Ausgleichsfeder 6 umgreift die Zugstange 5 und stützt sich einerseits-auf einer Scheibe 3 ab, die an ihrem äusseren Umfang auf einer Sicke 4b des Tragrohres 4 aufsitzt. Das andere Federende drückt über eine Unte : legscheibe 2 gegen die auf der Zugstange 5 verstellbar angeordnete Rundmutter 1. In das Tragrohr 4 ist an der über der Rundmutter 1 gelegenen Stelle ein fensterartiger Ausschnitt 4a angeordnet, dessen Breite und Länge so gewählt sind, daß die Rundmutter bequem mit einem in die Sacklöcher la eingesetzten Dorn verstellt werden und damit die Spannkraft der Ausgleichsfeder 6 verändert werden kann. AnsprücheThe tie rod 5 of the compensating device, which is arranged concentrically in the support tube 4 of the swivel arm, has a thread for an adjusting nut l, which is advantageously provided as a round nut with several blind holes la for attaching a mandrel wrench. ßs can of course also be another parent form, z. B. a hex nut can be used. The compensating spring 6 engages around the pull rod 5 and is supported on the one hand on one Disk 3 from, which on its outer circumference on a bead 4b of the Support tube 4 is seated. The other end of the spring presses over a bottom: Washer 2 against the adjustable round nut 1 arranged on the tie rod 5. In the support tube 4, a window-like cutout 4a is arranged at the point above the round nut 1, the width and length of which are chosen so that the round nut can easily be inserted into the blind holes la inserted mandrel can be adjusted and thus the tension force of the compensating spring 6 can be changed.
