Abstract
A camera pedestal has wheels that can be positively steered via a steering bar operating a corrective and crab mode steering system, and that may also be uncoupled from the steering system and operated in a caster wheel mode. The pedestal includes a base having a chassis and four leg assemblies. Each leg assembly has an upper component rotatably attached to the chassis, and wheels attached to a lower component via a caster fitting. The caster fitting allows the wheels to be positioned in a normal position where they are aligned with the rotation axis of the leg assembly, and into a caster position where the wheels are offset from the rotation axis, to allow for caster rolling movement.
Claims16
A camera pedestal comprising:
- a base having a chassis;
- first, second, third and fourth leg assemblies having a first component rotatably attached to the chassis on a steering axis, and a second component attached to the first component;
- at least one axle on the second component and at least one wheel rotatably attached onto the at least one axle;
- with the second component moveable relative to the first component into a first position wherein the at least one axle is aligned on the steering axis, and into a second position wherein the at least one axle is offset from the steering axis;
- and
- with the first component comprising a hollow tubular upright, further including a leg sprocket on the upright and a chain extending around the leg sprocket and around a transmission sprocket in a steering transmission in the chassis.
5-6. (canceled)
A camera support comprising:
- a chassis with first, second, third and fourth leg assemblies rotatably attached to the chassis;
- a wheel set rotatably attached onto a lower end of each leg assembly;
- a caster fitting on each leg assembly for positioning the wheel set into a normal position and into a caster position;
- a leg sprocket on each leg assembly and a sprocket locking mechanism on each leg assembly for locking the leg sprocket for rotation with the leg assembly, and for releasing the leg sprocket to allow the leg assembly to rotate freely of the leg sprocket;
- and
- a steering transmission in the chassis having a first chain extending around the leg sprockets of the first and second leg assemblies, a second chain extending around the leg sprocket of the third leg assembly, and a third chain extending around the leg sprocket of the fourth leg assembly.
A camera pedestal comprising:
- a base having a chassis;
- first, second, third and fourth leg assemblies having a hollow tubular upright rotatably attached to the chassis on a steering axis, with the hollow tubular upright extending vertically entirely through the chassis, with the hollow tubular upright having an open top end and a key or keyway for engaging a steering bar;
- and a caster fitting attached to the hollow tubular upright and at least one axle on the caster fitting and at least one wheel rotatably attached onto the at least one axle;
- with the caster fitting moveable relative to the hollow tubular upright into a first position wherein the at least one axle is aligned on the steering axis, and into a second position wherein the at least one axle is offset from the steering axis;
- and
- a leg sprocket on the hollow tubular upright and a chain extending around the leg sprocket and around a transmission sprocket in a steering transmission in the chassis.
