Device for supporting ergonomic unit e.g. beam, in industrial tool, has four feet cooperating with base, where longitudinal axes of foot and longitudinal axes of feet describe directed angle whose absolute value is higher than given value

摘要

The device has a base (B) and four feet (F1-F3) that is intended to cooperate with the base. A set of proximal parts of the four feet is arranged to cooperate with the base according pivot connections in a set of directions. The base is arranged with a safety unit that cooperates with the feet as soon as two feet (F1, F2) are approximately parallel to limit rotation of any other foot (F3, F4). Longitudinal axes (a3, a4) of the foot and longitudinal axes (a1, a2) of the feet describe a directed angle (alpha) whose absolute value is higher than given value. An independent claim is also included for an industrial tool.
