Description
Neigungsvorrichtung für photographische Kameras. Die Erfindung betrifft eine NeigungsvGrrichtung für Stativköpfe. Derartige Vorrichtungen sind bekannt. Bei den bekannten Vorrichtungen dieser Art ist an der Unterseite der Auflageplatte ein halbkreisförmiges Zahnsegment angebracht, in welches ein Schneckenrad eingreift, das mit einer Kurbel verbunden ist. Bei derartigen Vorrichtungen kann toter Gang eintreten. Dies muß vermieden werden, da infolge toten Ganges bei der Vorstellung die kinematographische Aufnahmekamera beim Kurbeln wackelt und dadurch der Film bei der Wiedergabe unruhige Bilder ergeben würde. Auch läßt sich ein derartiger Antrieb schwer einkapseln, um das Verschmutzen des Schnekkengetriebes zu verhindern.Tilting device for photographic cameras. The invention relates to a tilt device for tripod heads. Such devices are known. In the known devices of this type is on the underside of the platen a semicircular tooth segment attached, in which a worm wheel engages, that is connected to a crank. In such devices there can be dead gear enter. This has to be avoided, as it results in a dead passage during the presentation the cinematographic recording camera wobbles when cranking and thus the film would result in unsteady images during playback. Such a Encapsulate the drive heavily to prevent contamination of the worm gear.
Nach der Erfindung sind deshalb wechselseitig an einer Welle angreifende Stahlbänder oder -drahtseile mit dem Neigungsantrieb der Kameraauflageplatte verbunden. Es wird bemerkt, daß die Verwendung von Stahlbändern an sich zum Heben von Kameras bekannt ist.According to the invention are therefore mutually acting on a shaft Steel bands or wire ropes connected to the tilt drive of the camera support plate. It is noted that the use of steel straps per se for lifting cameras is known.
Auf der Zeichnung ist ein Stativkopf nach der Erfindung dargestellt, und zwar zeigen Abb. i ihn von vorn, Abb. z von der Seite in teilweisem Schnitt. Zwischen Lagern i ist ein kleines Schneckenrad a drehbar, welches über ein Kegelräderpaar 3 mittels einer Kurbel .4 bewegt werden kann. An dieser Bewegung nehmen auch Scheiben 5, 6, die auf der gleichen Achse wie das Schneckenrad a sitzen, teil. Um diese sind Stahlbänder'-,7,8 herumgeschlungen, und zwar in einander entgegengesetzten Richtungen. Die Bänder laufen auf Gleitflächen g, io nach einer Auflageplatte i i, an welcher das eine Band 8 bei 12 fest, das andere 7 an einer verstellbaren Befestigung 13 angreift, welche die Spannung der Bänder einzustellen gestattet.In the drawing, a tripod head according to the invention is shown, Fig. i shows it from the front, Fig. z from the side in partial section. A small worm wheel a can be rotated between the bearings i, which via a pair of bevel gears 3 can be moved by means of a crank .4. Slices also take part in this movement 5, 6, which sit on the same axis as the worm wheel a, part. To these are Steel bands' -, 7,8 wrapped around in opposite directions. The bands run on sliding surfaces g, io after a support plate i i, on which one band 8 fixed at 12, the other 7 at an adjustable fastening 13 attacks, which allows the tension of the ligaments to be adjusted.
