Abstract:
Pivotal apparatus, comprising:a first pivoting member pivotal about a first pivot axis; a second pivoting member pivotal about a second pivot axis spaced from said first pivot axis, said second pivot axis 1) being pivotable in a first plane that is parallel to said first pivot axis through a range of angles with respect to said first pivot axis; and 2) being movable in a direction normal or essentially normal to said first plane through a range of displacement distances relative to said first pivot axis; and an actuating linkage assembly connecting said first and second pivoting members such that pivoting of said first pivoting member about said first pivot axis effects driven pivoting of said second pivoting member about said second pivot axis, said actuating linkage assembly being configured such that said driven pivoting results for any angular position of said second pivot axis within said range of angles and for any displacement distance of said second pivot axis within said range of displacement distances.
