US Patent 11559138 Workcell

A workcell comprises a base structure, a column having a lower part connected to the base structure and an upper part which is height-adjustable relative to the lower part. A first and a second support structure are mechanically connected to the upper part of the column via a first and a second joint element to allow axial rotation of the support structures around the column. At least one of the joint elements comprises a latching mechanism configured to block movement of the joint element with respect to the column in a normal state and to release movement of the joint element during an adjustment operation initiated by a user of the workcell.
