US Patent 7588378 Camera tripod head with weight compensation

A camera-support head includes a stator and a rotor that is mounted so that it can be rotated about an inclined axis in relation to the stator. The head also includes a compensation device for compensating a load torque that occurs during the inclination, the device having an energy accumulator which exerts a restoring torque on the rotor during the inclination. In addition, the compensation device has an auxiliary device which influences the transmission of the rotational displacement from the rotor to the energy accumulator and thus also the restoring torque that is exerted on the rotor by the energy accumulator.
