Description
Stativ. Die Erfindung bezieht sich auf ein Stativ, beispielsweise für kinematographische Aufnahmeapparate, das aus einer Tragplatte und mehreren, in der Regel drei Füßen mit je zwei Schenkeln besteht, die nach unten dreieckförmig zusammenlaufen und mit den an der Grundlinie des Dreiecks liegenden freien Schenkelenden in einer einzigen parallel zur Tragplatte liegenden Ebene gelenkig gelagert sind.Tripod. The invention relates to a tripod, for example for cinematographic recording apparatus, which consists of a support plate and several, usually three feet with two legs each, which are triangular downwards converge and with the free leg ends lying on the base line of the triangle are articulated in a single plane lying parallel to the support plate.
Stative dieser Art sind gewöhnlich im wesentlichen nach Abb. i der Zeichnung so ausgeführt, daß die beiden Schenke13 eines jeden Fußes einen radialen Vorsprung 2 der Platte i zwischen sich fassen. Hierbei hat das Stativ nur eine beschränkte Standfestigkeit, weil jeder Fuß einseitig an der Platte angreift und die Breite der Angriffsfläche nur gering im Verhältnis zum Gesamtumfang der Platte ist.Tripods of this type are usually essentially as shown in Fig Drawing carried out so that the two Schenke13 of each foot a radial Grasp projection 2 of the plate i between you. Here the tripod has only a limited one Stability, because each foot engages the plate on one side and the width the area of attack is only small in relation to the total circumference of the plate.
Gemäß der Erfindung liegen, um diesem Mangel abzuhelfen, die beiden Gelenke eines jeden Fußes an den beiden Enden einer .geraden Linie, die durch die Mitte der Tragplatte geht, so daß die Achsen aller Gelenke sich in der gemeinsamen Ebene in einem einzigen Punkte schneiden.According to the invention, in order to remedy this deficiency, the two lie Joints of each foot at the two ends of a straight line passing through the Center of the support plate goes so that the axes of all joints are in the common Intersect the plane in a single point.
Es ist zwar bereits vorgeschlagen, die Gelenke jedes einzelnen gegabelten Fußes eines Stativs in einander gegenüberliegenden Punkten :anzuordnen, jedoch nur bei einem Stativ, bei dem die Gelenke der verschiedenen Füße in verschiedenen wagerechten Ebenen liegen. Solche Stative werden z. B. für kinematographische Aufnahmegeräte nicht standfest genug sein, da das Gewicht des daraufger setzten Apparats ein Kippmoment erzeugt.Although it has already been suggested that the joints of every single one be forked Base of a tripod in opposite points: to be arranged, but only in the case of a tripod in which the joints of the different feet are in different horizontal positions Levels lie. Such tripods are z. B. for cinematographic recording devices not be stable enough, as the weight of the apparatus placed on it creates a tipping moment generated.
Ein Ausführungsbeispiel der Erfindung ist schematisch in den Abb. 2 und 3 dargestellt. Abb. z ist eine Draufsicht -des Stativs, Abb. 3 eine schaubildliche Ansicht.An embodiment of the invention is shown schematically in Fig. 2 and 3 shown. Fig. Z is a top view of the tripod, Fig. 3 is a perspective view Opinion.
Die Tragplatte ¢ hat hier die Form eines Zwölfecks, so daß je zwei symmetrisch zu ihrem Mittelpunkt 5 einander gegenüberliegende Seiten unter sich parallel sind. Jeder Fuß 6 bildet in bekannter Weise eine Gabel, deren parallel zueinander abgebogene Schenkelenden erfindungsgemäß an zwei einander gegenüberliegende Umfangsflächen des Tisches angelenkt sind, und kann mittels Flügelmuttern 7, die auf Gewindebolzen 8 aufgesetzt sind, festgelegt werden.The support plate ¢ here has the shape of a dodecagon, so that two symmetrically to its center 5 mutually opposite sides below are parallel. Each foot 6 forms a fork in a known manner, the parallel leg ends bent towards one another according to the invention on two opposite one another Peripheral surfaces of the table are hinged, and can by means of wing nuts 7, the are placed on threaded bolts 8, are set.
Durch diese Anordnung erlangt das Stativ völlige Standsicherheit. Es kann sich weder verschieben noch verstellen. Beim Aufklappen` und Zusammenlegen des Stativs gleiten die Füße mit ihren Flachseiten aufeinander.This arrangement gives the tripod complete stability. It can neither move nor adjust. When unfolding and folding of the tripod, the feet slide on one another with their flat sides.
Die Platte kann auch jede andere geeignete pol-gonale, z. B. Sechseckform erhalten. Ebenso können die beiden einander gegenüberliegenden Vieleckseiten, an denen die beiden Schenkel der Gabel eines Fußes befestigt sind, in ungleichen Abständen vom Mittelpunkt liegen.The plate can also have any other suitable pol-gonal, e.g. B. hexagonal shape obtain. Likewise, the two opposite polygon sides can to which the two legs of the fork of a foot are attached, at unequal intervals from the center.
