"Aufhängung für eine Last""Suspension for a load"

Die Erfindung betrifft eine Aufhängung für eine Last gemäß Oberbegriff des Anspruchs 1.The invention relates to a suspension for a load according to the preamble of claim 1.

Bei bekannten Aufhängungen werden Federn zum Gewichtsausgleich benutzt, um das System in jeder Winkelstellung im Gleichgewicht zu halten. Schwierigkeiten bereitet der Ausgleich des Lastmomentes bei großen Verstellbereichen,und es kommt daher bei derartigen Konstruktionen oft vor, daß wegen nicht ausreichend genauer Abstimmung von Federmoment und Lastmoment die Last wieder in Richtung auf die Ausgangsstellung sich zurückbewegt, nachdem sie vom Benutzer in eine andere gewünschte Position gezogen wurde.In known suspensions springs are used to counterbalance the system in every angular position in equilibrium to keep. Difficulties are encountered in balancing the load torque in the case of large adjustment ranges, and that is where it arises in such constructions it is often found that because of insufficient precise coordination of spring torque and load torque the load back in the direction of the starting position moved back after being dragged to another desired position by the user.

Man hat daher versucht, zusätzliche Reibelemente einzubauen, so daß das Stehenbleiben der Last in jeder Stellung leichter gewährleistet werden könnte. Dabei ist jedoch nachteilig, daß sowohl der Verschleiß als auch die notwendige Verstellkraft größer werden.Attempts have therefore been made to incorporate additional friction elements so that it is easier for the load to stop in any position could be guaranteed. However, it is disadvantageous that both the wear and the necessary adjusting force grow.

Es ist Aufgabe vorliegender Erfindung, eine technische Lehre für die genaue Dimensionierung eines abgestimmten Federausgleiches bei der Aufhängung einer Last gemäß Oberbegriff desIt is the object of the present invention to provide a technical teaching for the precise dimensioning of a coordinated spring compensation when suspending a load according to the preamble of

Anspruchs 1 zu geben. Gelöst wird diese Aufgabe durch die im Kennzeichen des Anspruchs 1 aufgeführten Merkmale.Claim 1 to give. This task is solved by the in the characterizing part of claim 1 listed features.

Weitere Ausgestaltungen der Erfindung sowie eine vorteilhafte Verwendung sind den Unteransprüchen zu entnehmen.Further refinements of the invention and an advantageous use can be found in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in den beigefügten Zeichnungen rein schematisch dargestellt. Es zeigen:An embodiment of the invention is shown purely schematically in the accompanying drawings. Show it:

Figur 1 die Aufhängung einer Last, wie Leuchte, teilweise im Schnitt,Figure 1 the suspension of a load, such as a lamp, partially in section,

Figur 2a die Stellung der Arme vor der Montage des Zugmittels und der Last (Feder entspannt),Figure 2a shows the position of the arms before the assembly of the traction mechanism and the load (spring relaxed),

Figur 2b die Stellung der Arme, bei der der Hebelarm E eine horizontale Lage einnimmt (Feder gespannt, Last angehängt).Figure 2b shows the position of the arms in which the lever arm E assumes a horizontal position (spring tensioned, Load attached).

Wie der Figur 1 zu entnehmen, ist die Last 1 an einer Decke, einer Wand oder einem Stativ 2 entweder horizontal oder vertikal aufhängbar bzw. befestigbar über einen Tragarm 3 und einen Haltearm 4.As can be seen from FIG. 1, the load 1 is either horizontal or on a ceiling, a wall or a stand 2 can be suspended or fastened vertically via a support arm 3 and a holding arm 4.

Mit Vorteil ist der Haltearm 4 mittels eines Zwischenstücks 5 planetenartig drehbar um eine zentrale Achse 6 angeordnet. In dem Haltearm 4 sind eine Feder 7, ein Zugmittel 8, eine Umlenkrolle 9 und ein Drehgelenk 10 so untergebracht, daß an einem Punkt P die Federkraft auf den Tragarm angreift und diesen in einen Kraftarm E und einen Lastarm aufteilt. Der AnstellwinkelcC(vergleiche Bild 2a) ist frei wählbar. Wesentlich ist, daß verglichen mit dem Zustand vor der Montage (Fig. 2a) - bei der Horizontallage des Hebelarms E (Fig. 2b) die im Kennzeichen des Anspruchs 1 genannte Bedingung eingehalten wird.The holding arm 4 is advantageously arranged so as to be rotatable about a central axis 6 in the manner of a planet by means of an intermediate piece 5. In the holding arm 4, a spring 7, a traction means 8, a pulley 9 and a swivel joint 10 are housed so that on one Point P attacks the spring force on the support arm and divides it into a force arm E and a load arm. The angle of attack cC (compare Figure 2a) can be freely selected. It is essential that compared with the state before assembly (Fig. 2a) - in the horizontal position of the lever arm E (Fig. 2b), the condition mentioned in the characterizing part of claim 1 is met will.

Besonders bewährt hat sich die Verwendung der Aufhämgung für eine Operationsleuchte als Last mit einem Gewicht von 400 Newton, einer Länge zwischen Drehgelenk 10 und Aufhängepunkt des Leuchtengehäuses in der Horizontalen von 1000 mm, einer Länge des Kraftarms E von 30 mm und einer wirksamen Länge des Zugmittels A von 90 mm. Der Winkel oC betrug dabei 63°.The use of the suspension has proven particularly useful for a surgical light as a load with a weight of 400 Newtons, a length between the swivel joint 10 and the suspension point of the luminaire housing in the horizontal of 1000 mm, a length of the power arm E of 30 mm and an effective Length of the traction device A of 90 mm. The angle oC was thereby 63 °.

Der wesentlichste Vorteil der Erfindung ist, daß das Moment der Last durch die Abstimmung des Federmoments über den gesamten Verstellwinkelbereich stets gut ausgeglichen ist mit der Folge, daß die Last in jeder gewünschten Stellung stehenbleibt.The main advantage of the invention is that the moment of the load by the coordination of the spring torque on the entire adjustment angle range is always well balanced, with the result that the load is in any desired position stop.
