Abstract

The automatically leveling rail comprises a rail element as a functional unit. The rail element works independently or in an interconnection with other automatically leveling rail elements. Each rail element is provided with bases, which is extended or retracted by computer control. Individual rail element or the group of an indefinite number of automatically rail elements are positioned in horizontal level.

Description

For filming be a shocking and tipping to get free image tracks, over the the camera is moved with the help of a dolly or a crane. The rail consists of elements of equal and / or different length the together to the desired overall length get connected. To get the picture mentioned above all Precise elements be aligned in the same plane. Differences are made by bumping or tilting the image noticeable.

State of the art:

The conventional The procedure is first one side of the entire rail length; With Help of spirit level, good judgment and Substructure (blocks, Crates, wedges, cardboard and the like in different thicknesses) at the joints of the elements; into an escape and if necessary bring into balance and then with the help of spirit level and substructure aligned the other side. It follows further substructure to stabilize the construction. This may be the position of Do not change the rail, otherwise a new orientation must follow.

This Process takes a certain amount of time, depending on the length of the process planned camera movement and underground. For example, in a circular drive which consists of only 8 elements, is a construction time of 1 h (at light uneven but firm ground) not uncommon.

Not rarely does a cameraman / woman have to adjust to a timed setting establish without.

With the technique mentioned in the claim is intended to prolong the problem Construction times are significantly reduced. Likewise, this is to be supplied with substructure material to a minimum for reduced special cases become.

This is achieved by placing the rail elements only together and need to be connected The leveling is controlled by a computer that collects the data the connected sensors and the data of the other rail elements (if available) processed in the way he puts his feet on the to reach the desired Location required length off or on leads. To meet the requirements of film everyday life there are two program settings, "Flat" controls the feet that way all elements with as possible small distance to the ground the same angle so have exactly lie in an alignment and only the narrow side exactly horizontal is aligned; "Water" controls the feet that way the narrow and the long side aligned exactly and horizontally are in a run, if possible less distance to the ground. The second program setting leads as well without data connection (only with mechanical connection) between the individual rail elements to the desired horizontal orientation, so that with rail elements that are used exclusively horizontally, z. For example Camera cranes, on the data connection and on the program setting "Flat" be waived can.

• • Reduzierung der Aufbauzeit auf einen Bruchteil,
• • bei verbesserter Genauigkeit,
• • die einzelnen Schienenelemente müssen nur zur gewünschten Länge verbunden werden die sonst zeitaufwendige Nivellierung wird von der Automatischen Steuerung übernommen,
• • auch Hilfskräften ist der Aufbau möglich, so das dem/der Bühnenmann/frau mehr Zeit und Kraft für seine/ihre anderen Aufgaben bleibt,
• • Reduzierung der Menge an Unterbau, es muss nur noch Unterbau für sehr große Unebenheiten oder zur Vergrößerung der Auflage bei weichem Untergrund bereitgehalten werden
• • zudem kann das System, im dem Fall das auf weichem Untergrund ein oder mehrere Stützen unter Last absacken, gegensteuern und so die Sicherheit des Aufbaus erhöhen.

Advantages achieved by the invention are

• • Reduction of set-up time to a fraction,
• • with improved accuracy,
• • the individual rail elements only have to be connected to the desired length otherwise the time-consuming leveling is taken over by the automatic control,
• • Auxiliary staff can also be set up so that the stage manager has more time and energy for his / her other tasks.
• • Reduction of the amount of substructure, only substructure for very large unevenness or to increase the support on soft ground must be kept ready
• • In addition, in the event that one or more supports collapse under load on a soft ground, the system can counteract this and thus increase the safety of the bodywork.

The embodiment illustrated by the following drawings and explanations the Function of the invention.
