Abstract
A steering compensator has a shaft with a first shaft section offset from a central shaft section. A second shaft section of the shaft is offset from the first and central shaft sections. A first drive member is rotatably attached to the first shaft section and a second drive member is rotatably attached to the second shaft section. A central member is rotatably attached to the central shaft section between the first and second drive members. A pivotal link interconnects the first and second drive members through the central member to allow relative angular displacement between the first and second drive members. The steering compensator provides steering angle correction in conventional steering.
Claims16
A steering compensator comprising:
- a shaft having a first shaft section, a central shaft section offset from the first shaft section and a second shaft section offset from the first and central shaft sections;
- a first drive member rotatably attached to the first shaft section;
- a second drive member rotatably attached to the second shaft section;
- a central member rotatably attached to the central shaft section between the first and second drive members;
- and
- means for pivotally linking said first and second drive members to allow relative angular displacement between them.
A camera dolly having an adjustable steering angle corrector comprising:
- a shaft having first shaft section, a hub section, and a second shaft section, offset from each other;
- an eccentric collar pivotally supported on the first shaft section;
- a first drive member rotatably supported around the eccentric collar;
- a hub rotatably supported on the hub section;
- means for linking the eccentric collar and the hub;
- a second drive member rotatably supported on the second shaft section;
- and
- means for linking the first drive member and the second drive member.
A camera dolly having a steering system including a steering compensator comprising:
- an offset shaft having an upper segment eccentrically attached to a center segment, and a lower segment eccentrically attached to the center segment opposite to the upper segment;
- an upper sprocket rotatably and concentrically attached around the upper segment;
- a center disk rotatably attached around the center segment;
- a lower sprocket rotatably and eccentrically attached around the lower segment;
- and
- a connecting link pivotably joining the upper sprocket and lower sprocket through the central disk.
