A support apparatus for a portable weight such as a camera comprising at least a pair substantially friction-free arms which are rotatably and pivotally interconnected at a hinge bracket. One end of the interconnected pair of arms is rotatably and pivotably connected to a mount which may be worn by an operator or attached to a movable support. The other end is adapted to carry a weight such as a camera. Each arm is parallelogram in configuration and is provided with a segmented spring designed to apply a constant force to compensate for the weight applied to the end of each arm. The segmented spring acts as a single spring mounted diagonally across the parallelogram and exerts a force which is equal to the weight applied to the end of the parallelogram arm times the length of its diagonal divided by the distance between the attachment points of the parallelogram to the hinge bracket. In operation, the weight carried by the support apparatus is spacially decoupled from the mount to increase isolation of the weight from the operator or support.
A weight support apparatus system especially adapted for operation as a portable device on a moving carrier and capable of being hand-guided by an operator, the system being of improved stability against angular deviations in pan, tilt and roll, and substantially free-floating in a manner to also isolate the weight from unwanted lateral and vertical movement caused by the motion of the carrier which comprises;
The support apparatus system of claim 10 wherein the first support arm comprises a first resilient means, said first resilient means continuously biasing the end of the first arm that is remote from the carrier upwardly relative to the carrier, the bias of the first resilient means being substantially balanced by the weight to cause the weight to free float irrespective the movement of the carrier.
A support apparatus for supporting a portable device on a moving carrier comprising:
A weight support apparatus system especially adapted for supporting a portable device on a moving carrier, the system supporting the device with improved stability against angular deviations in pan, tilt and roll in a substantially free-floating manner to also isolate the device from unwanted lateral and vertical movement caused by the motion of the carrier which comprises:
