Holder for information media such as signs, advertisements etc. has variable weights for balancing entire system and concentrates variably-spaced centers of gravity on foot

摘要

The holder is able to concentrate variably-spaced centers of gravity on a base foot using variable weights to balance the system and place it in a neutral setting. The weight of the object being held is over-proportionally visualized by unfavorable lever fulcrums. Servo motors, pneumatic, hydraulic or other drives may be included to change the height and position.
