Patent ID: 7588378

Claim:
Tripod head with a stator and a rotor, which is rotatable around a tilt axis in relation to the stator, as well as a compensating device for compensation of a weight moment arising during a tilt movement of the rotor, said device having an energy storage device, which exerts a restoring moment on the rotor during the tilt movement, wherein the compensating device has an auxiliary device, which brings about the transmission of the rotational movement from the rotor to the energy storage device and thus also influences the restoring moment exerted on the rotor by means of the energy storage device, and which has a shaft likewise pivoted around an axis in relation to the stator and means for transmitting the rotational movement of the rotor to the shaft with the result that during the tilt movement the restoring moment exerted on the rotor by means of the energy storage device is influenced by the rotation of the shaft around its axis, and wherein the auxiliary device has a roll contact gear which is formed by a roll contact area of the rotor and a roll contact area of the auxiliary device whereby the shape of the cross-section of these roll contact areas is optimized such that the restoring moment changes essentially sinusoidally with the tilt angle.
