Abstract

The mechanical interlock prevents inadvertent engagement of a control member. Rotation of the mechanical interlock about an interlock axis from a locked position to an engagement position allows the control member to rotate about a control axis. The mechanical interlock includes an interlock bracket that defines a guide path having locking and actuating segments that intersect at an acute angle, and a guide member that engages the guide path. One of the interlock bracket or the guide member is pivotally coupled to the control member about the interlock axis and the other is coupled to a handle. The guide path and the guide member are selectively positionable between a locked position where the guide member is proximate the locking segment, an engaged position where the guide member is proximate the intersection, and an actuated position where the guide member is proximate the actuating segment.
