Abstract
The tilting and rotating sunshade has a counterweight (2) attached to it in such a way as to produce zero torque in the mobile section. The angles of tilt and rotation of the sunshade can be adjusted with little physical effort. The sunshade can be locked in position to prevent that position from being altered by the wind. The counterweight (2) can be attached to the sunshade with pins, cables, chains (5) and toothed wheels. These connections of the counterweight (2) to the sunshade make it possible to set up the sunshade in particularly advantageous locations, e.g. under a table (3) in whose centre the sunshade column is situated.

Beschreibung description
Drehmomentfrei gelagerter kipp- und drehbarer SonnenschirmTorque-free, tilting and rotating parasol
Die Erfindung betrifft einen drehmomentfrei gelagerten kippbaren Sonnen-x-hirm ge¬ mäß den in Oberbegriff des Anspruches 1 angegebenen Merkmalen. Ein solcher So-mei-schirm ist aus der Patentschrift US 3486514 bekannt. Durch die Anordnung des Gegengewichts direkt auf dem Tragarm ist die Position des des Ge¬ gengewichtes durch die Position des Schirmdaches weitgehend bestimmt. Hierdurch wird anderweitig besser nutzbarer Raum verbraucht und der gesamte Sonnenschirm wirkt groß und sperrig. Außerdem beeinflußt das direkt auf dem Tragarm angeordnete Gegengewicht das Aussehen des Schirmes in unvorteilhafter Weise.The invention relates to a torque-free tiltable sun x hirm ge according to the features specified in the preamble of claim 1. Such a So-mei screen is known from the patent US 3486514. By arranging the counterweight directly on the support arm, the position of the counterweight is largely determined by the position of the canopy. In this way, more usable space is used and the entire parasol appears large and bulky. In addition, the counterweight arranged directly on the support arm adversely affects the appearance of the screen.
Der Erfindung hegt die Aufgabe zugrunde, das Gegengewicht an einem günstige¬ ren Platz zu positionieren und das Aussehen eines Schirmes der eingangs genannten Art zu verbessern. Diese Aufgabe wird bei einem gattungsgemäßen Schirm mit den im kennzeichnenden Teil des Anspruchs 1 genannten Merkmalen gelöst. Infolge die¬ ser Ausbildung kann der Einbauort des Gegengewichtes so gewählt werden, daß dieses nicht stört. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteran¬ sprüchen. Anhand von Figur 1 wird ein bevorzugtes Ausführungsbeispiel der Erfindung erläutert. Dabei ist: (1) das Schirmdach, (2) das Gegengewicht, (3) ein Tisch, (4) Zahn¬ räder, die durch eine Kette (5) miteinander verbunden sind, (6) der Tragarm und (7) der Hebelarm. Das Kraftübertragungsmittel besteht hier aus den Zahnrädern (4) und der Kette (5). Die Zahnräder sind starr mit dem Tragarm bzw. mit dem Hebelarm verbunden und drehbar im vertikalen Standmast, der z. B. aus zwei Rundhölzern oder zwei Metallrohren besteht, gelagert. Das Gewicht des Gegengewichts ist so groß, daß es zusammen mit dem Hebelarm ein gleich großes aber entgegengesetzt gerichtetes Dreh¬ moment bewirkt wie das Schirmdach zusammen mit dem Tragarm. Im allgemeinen ist der Abstand des Schwerpunktes des Gegengewichtes vom zweiten Lager kleiner als der Abstand des Schwerpunktes des Schiπndaches vom ersten Lager und das Gewicht des Gegengewichts daher höher als das des Schirmdaches. Um das Volumen des Gegenge¬ wichtes klein zu halten empfehlen sich Materialien hoher Dichte z. B. Blei. Kipp- und
Drehwinkel des Sonnenschirmes lassen sich jetzt mit geringem Kraftaufwand verstellen. Damit die Position des erzeugten Schattens nicht vom Wind geändert wird, kann die Lage des Schirmdaches verriegelt werden. Das Gegengewicht kann auch durch Stangen oder Seile mit dem Schirmdach verbunden sein. Wesenthch ist in jedem Fall, daß das resultiernde Drehmoment für alle Kipp- und Drehwinkel ungefähr Null ergibt.
The object of the invention is to position the counterweight in a more favorable place and to improve the appearance of a screen of the type mentioned at the beginning. This object is achieved in a generic umbrella with the features mentioned in the characterizing part of claim 1. As a result of this design, the installation location of the counterweight can be chosen so that it does not interfere. Advantageous developments of the invention result from the subclaims. A preferred exemplary embodiment of the invention is explained with reference to FIG. Thereby: (1) the canopy, (2) the counterweight, (3) a table, (4) gear wheels, which are connected by a chain (5), (6) the support arm and (7) the lever arm . The power transmission means consists of the gears (4) and the chain (5). The gears are rigidly connected to the support arm or with the lever arm and rotatable in the vertical standing mast, the z. B. consists of two logs or two metal tubes, stored. The weight of the counterweight is so great that, together with the lever arm, it produces the same torque, but in the opposite direction, as the umbrella roof together with the support arm. In general, the distance of the center of gravity of the counterweight from the second bearing is smaller than the distance of the center of gravity of the roof from the first bearing and the weight of the counterweight is therefore higher than that of the umbrella roof. In order to keep the volume of the counterweight small, materials of high density are recommended, e.g. B. lead. Tilting and The angle of rotation of the parasol can now be adjusted with little effort. The position of the canopy can be locked so that the position of the generated shadow is not changed by the wind. The counterweight can also be connected to the canopy by rods or ropes. It is essential in any case that the resulting torque results in approximately zero for all tilt and rotation angles.
