Definitions

  • Telescopic camera crane with automatic leveling and directly driven pan and tilt head
  • the invention relates to a camera crane, the support of which extend and retract telescopically at variable speed, while its counterweight is also proportionally adjusted so that the crane always remains balanced. Furthermore, the image horizon is held by an electric motor while the crane is being raised and lowered. The pan and tilt head is moved directly by electric motors.
  • Camera cranes allow the floating motion of a film or video camera during image acquisition.
  • Camera cranes work according to the "swing principle", in which a carrier is stored in the middle.
  • the pan and tilt head is attached to the camera at one end and counterweights at the other end to compensate.
  • the invention significantly increases the freedom of image design.
  • the camera can be moved and positioned as desired between the minimum and maximum crane radius at infinitely variable speed.
  • the telescopic camera crane simplifies normal filming and enables previously impossible camera movements.
  • the invention is described below with the aid of a drawing.
  • the drawing shows the telescopic camera crane in its shortest and longest state as well as with the highest and lowest camera position.
  • the crane is stored in its center (1). While the carriers are pulled out and in with ropes, the counterweights (2) move away from the center or towards the center.
  • the counterweights travel on a slide on the outermost carrier and are pulled by a toothed belt (3).
  • the toothed belt and the ropes are driven by an electric motor via a common axis. As a result, when the crane arm is almost vertical, the counterweight helps the electric motor push out the beams.
  • the number and position of the counterweights on the slide can be adjusted. This is the only way to adapt the telescopic camera crane to the different camera weights.
  • the center (1) there is a tachometer generator that reads the tilting speed of the crane arm.
  • An electrical amplifier transmits the signal to an electric motor, which always keeps the suspension of the pan and tilt head horizontal via a worm gear.
  • a mercury switch on the suspension (5) continuously calibrates the horizon of the compensation system.
  • the stator is built into the stationary part (6) and the rotor into the rotating part (?) • The camera is rotated absolutely free of play and silently by the magnetic field.
