## Abstract

A support apparatus for a portable weight such as man carried camera comprising at least a pair of rotatably interconnected arms, one end of which is rotatably and pivotably supported by a support vest worn by an operator and the other end of which is arranged and configured to support weight such as a camera and a spring means provided on each arm to compensate for the weight applied to the end of each arm. In operation, the weight mounted on the support apparatus is spacially decoupled from the operator and the position of the weight is not affected by motion of the operator.

## Claims

### Claim 1

A weight support apparatus system especially adapted for operation as a portable device on a moving carrier and capable of being guided by the arm of an operator which comprises:
weight support means comprising first and second ends, the first end being connected to and adapted to support at least part of the weight, the second end being connected to the carrier,
said weight support means comprising at least a pair of first and second interconnected support arms, said support arms being adapted to damp out vibrations due to movement of the carrier,
each of the support arms comprising an upper and a lower longitudinal link and a medial bracket, which upper and lower links and medial brackets respectively form legs of a parallelogram, the respective upper and lower links and the medial bracket of each arm being pivotally interconnected to permit vertical rotative movement of one arm relative to the other, the first and second support arms each comprising respectively a first resilient means and a second resilient means, the first and second resilient means continuously biasing respectively the ends of the support arms that are remote from the carrier upwardly relative to the carrier, the bias of the first and second resilient means being substantially balanced by the weight, the first and second resilient means being connected respectively across the parallelograms to damp out vibrations caused by movement of the carrier and to cause the weight to free-float irrespective of movement of the carrier,
said weight support means substantially freeing the operator's hands from the weight and capable of being guided to a desired position selected by the operator; and
rotatable hinge bracket means interconnecting the medial brackets of the support arms, the hinge bracket means comprising a vertical pivot pin to permit horizontal rotatable movement of one arm relative to the other,
whereby the weight is isolated and free-floating at a distance from the operator substantially independent of any unwanted lateral and vertical vibrations caused by motion of the carrier.

### Claim 2 (depends on 1)

The weight support apparatus system of claim 1, wherein the hinge bracket means comprises means to duplicate the movements of the operator's arm by permitting rotation of the first support arm about the pivot pin relative to the second support arm from a substantially aligned position to a substantially parallel position in a first direction and by prohibiting rotation of the first support arm about the pivot pin relative to the second support arm from the substantially aligned position in a second opposite direction.

### Claim 3 (depends on 1)

The weight support apparatus system of claim 1 wherein the weight support means comprises hinge plate means at the end closest the carrier to permit horizontal rotatable movement of the support means relative to the carrier.

### Claim 4

A weight support apparatus system especially adapted for supporting a portable device on a moving carrier, the system supporting the device with improved stability in a substantially free-floating manner to isolate the device from unwanted lateral and vertical vibrations caused by motion of the carrier which comprises:
a pair of first and second interconnected, equipoising, parallelogram linkage support arms, said interconnected support arms having a first end adapted to be connected to the carrier and a second end adapted to be connected to the portable device;
first rotatable means interconnecting the support arms, said first rotatable means comprising a vertical pin adapted to permit horizontal rotatable movement of one support arm relative to the other;
a compressible and expandable means provided on each of the arms and adapted to exert a force across the diagonals of the parallelogram linkage of the said arms, said forces being sufficient to counteract the weight of the device applied at the said second end,
the compressible and expandable means exerting a damping force across the diagonals of the parallelogram linkages sufficient to damp out vibrations due to movement of the carrier;
second rotatable means interconnecting the said first end to the carrier, the said second rotatable means being adapted to permit horizontal rotatable movement of the interconnected arms relative to the carrier; and
third rotatable means forming portions of the first and second support arms, the third rotatable means comprising a plurality of horizontally oriented pivot pins, the pivot pins being adapted to permit vertical rotatable movement of one support arm relative to the other.

### Claim 5 (depends on 4)

The weight support apparatus system of claim 4 wherein the first rotatable means comprises a hinge including a pair of first and second hinge plates, the hinge plates being rotatably interconnected by the vertical pin.

### Claim 6 (depends on 5)

The weight support apparatus system of claim 5 and a first medial bracket forming part of the parallelogram linkage of the first support arm, the first hinge plate being affixed to the first medial bracket whereby the first support arm can be horizontally rotated about the pin.

### Claim 7 (depends on 5, 6)

The weight support apparatus system of claim 5 or 6 and a second medial bracket forming a part of the parallelogram linkage of the second support arm, the second hinge plate being affixed to the second medial bracket.
