Abstract

The steering column assembly has a base mounted to the machine and a steering column coupled to the base that pivots about the base at one end of the steering column. The steering column assembly has column plates and base plates with pinned ends and slotted ends. The pinned ends of the plates form pin openings. The column plates are pivotably coupled to the steering column with a column pin and the base plates are pivotably coupled to the base with a base pin. The column plates contact the base plates such that their respective slots intersect to form an opening through the slots. A locking pin fits in the opening and pushes the column plates against the base plates, creating friction between the plates that prevents the steering column from moving. When the locking pin is in an unlocked position the steering column is movable with at least two degrees of freedom. When the locking pin is in a locked position the steering column is not movable.
