Abstract
A geared head for a camera having a pan gearing means and a tilting means, the tilting means being mounted on the pan gearing means and having a mounting arm rotatably connected on the riser and rotatable about 360.degree.. The camera is mounted on a mounting plate attached to the mounting arm, the height of the mounting plate being adjustable so that the center of gravity of the camera may be positioned along the axis of rotation of the mounting arm. Once the camera is balanced on the mounting plate, the camera is neutrally balanced throughout its tilt range.
Claims17
A geared head for a camera, comprising a pan gearing means and a tilting means comprising:
- a riser having a first end and a second end, the first end mounted upon the pan gearing means, the riser being rotatable in a first plane by the pan gearing means;
- a mounting arm having one end rotatably connected to the second end of the riser so that the mounting arm rotates about 360.degree. in a second plane perpendicular to said first plane;
- a mounting plate suspended from the mounting arm;
- a side drive arm having a first end and a second end, the first end being pivotally mounted to the riser such that the side drive arm is rotatably positionable in a third plane perpendicular to the first plane;
- a tilt drive crank on the second end of the side drive arm;
- and
- drive transmitting means between the tilt drive crank and the mounting arm for rotating the mounting arm with the tilt drive crank.
