Abstract
An articulated jib for moving a load is supported on a base and comprises a first jib arm pivotably connected to a base. The first jib arm functions as a bascule and is pivotable about a first axis. There is a first counterweight disposed on the first jib arm. A second jib arm is pivotably connected to the first jib arm and is pivotable about a second axis. A linking rod connects the second jib arm to a lever arm which is also pivotably connected to the base. There is a second counterweight disposed on the lever arm.

An articulated jib for moving a camera, the jib being supported on a base and the jib comprising:
- a first jib arm pivotably connected to the base, the first jib arm functioning as a bascule and being pivotable about a first axis;
- a first counterweight disposed on the first jib arm;
- a second jib arm pivotably connected to the first jib arm, the second jib arm being pivotable about a second axis and the camera being disposed at a distal end of the second jib arm;
- a lever arm pivotably connected to the base and a linking rod connecting the lever arm to the second jib arm, the lever arm extending away from the linking rod towards a distal end of the lever arm, and the linking rod being pivotably connected to the second jib arm;
- a second counterweight disposed at the distal end of the lever arm;
- and
- wherein the first jib arm includes two parallel frame bars, each of the frame bars being pivotably connected to the base and connected to the second jib arm to form a parallelogram link mechanism, and wherein a length of the linking rod extending between its points of connection with the second jib arm and the lever arm is less than lengths of the frame bars of the first jib arm between their respective points of connection with second jib arm and the base.
An articulated jib for moving a camera, the jib being supported on a base which is rotatable about an axis and the jib comprising:
- a first jib arm including two parallel frame bars, each of the frame bars being pivotably connected to the base by corresponding pivot pins which are offset to one another having regard to the axis about which the base is rotatable, and the first jib arm functioning as a bascule and being pivotable about a first pivot axis;
- a first counterweight disposed on the first jib arm;
- a second jib arm pivotably connected to the first jib arm, the second jib arm being pivotable about a second pivot axis and the camera being disposed at a distal end of the second jib arm;
- a lever arm pivotably connected to the base and a linking rod connecting the lever arm to the second jib arm, the lever arm extending away from the linking rod towards a distal end of the lever arm, and the linking rod being pivotably connected to the second jib arm;
- a second counterweight disposed at the distal end of the lever arm;
- and
- wherein each of the frame bars of the first jib arm is also pivotably connected to the second jib arm by a corresponding pivot pin so as to form a parallelogram link mechanism and wherein a length of the linking rod between points of connection with the second jib arm and the lever arm is less than lengths of the frame bars of the first jib arm between their respective points of connection with second jib arm and the base.
A manually operable articulated jib for moving a camera, the jib being supported on a base and the jib comprising:
- a first jib arm pivotably connected to the base, the first jib arm functioning as a bascule and being pivotable about a first axis;
- a first counterweight disposed on the first jib arm;
- a second jib arm pivotably connected to the first jib arm, the second jib arm being pivotable about a second pivot axis and the camera being disposed at a distal end of the second jib arm;
- a lever arm pivotably connected to the base and a linking rod connecting the lever arm to the second jib arm, the lever arm extending away from the linking rod towards a distal end of the linking rod, the linking rod being pivotably connected to the second jib arm, and a length of the linking rod extending between its points of connection with the second jib arm and the lever arm being less than lengths of the frame bars of the first jib arm between their respective points of connection with second jib arm and the base;
- a second counterweight disposed at the distal end of the lever arm;
- and
- wherein the first jib arm includes two parallel frame bars, each of the frame bars being pivotably connected to the base and connected to the second jib arm to form a parallelogram link mechanism.
