Abstract: |
A mechanical control structure is used with a machine, such as a machine tool. The control structure includes a base and a tool support member connected by a linkage assembly having three linkages arranged in a triangular pattern. The linkages cooperate to prevent rotational movement of the tool support member relative to the base along any of the three rotational axes. Three linear actuators are also connected between the base and the tool support member to move the tool support member relative to the base along a predetermined path.

First Claim:

What is claimed:
1. A mechanical control structure for use in cooperation with a machine to limit the rotational movement of an object along the rotational axes as the object is moved by the machine through three dimensional space along a predetermined path, comprising:
- a base structure;
- an object supporting member; and
- a linkage assembly comprising a plurality of linkages, each linkage having:
- a first link pivotably mounted to one of the base structure or the object supporting member such that the first link is constrained to pivot about an axis with one degree of freedom, the first link including a reinforced region to provide greater structural rigidity; and
- a second link having a pair of arm members, each arm member being connected between a pivot joint on the first link and a pivot joint on the other of the base structure or the object supporting member, wherein the linkage assembly restricts movement of the object supporting member relative to the base structure along the rotational axes, further wherein the arm members within each pair of arm members are configured to remain parallel to one another as the object supporting member moves relative to the base structure.
