DEFINITION

Classification: 451/490

TOOL SUPPORT FOR FLEXIBLE-MEMBER TOOL:

(under the class definition) Device including an element or assembly of elements at least one of which is connected to a flexible-member tool for supporting it against gravity and that partakes of all the movement of the tool and has no relative movement with respect to the tool during operation of the class type.

(1) Note. A flexible-member tool when mounted on its support will not necessarily be flexible in operation or use due to rigidity of the support.
