Abstract
Abstract A mounting apparatus in which the vertical, lateral and torsional stiffness of the mounting apparatus are greater than the pivot stiffness. The greater stiffnesses are produced either by loading columns in tension or compression or by bending a rectangular column along its narrow, higher moment of inertia face.

Claim 1
Independent Claim
152 words
A mounting apparatus having an axis therethrough, the mounting apparatus comprising: a first and second mounting member, each mounting member being generally cylindrical in shape, the mounting members each being provided with an array of slots which cooperate to form in each member a first plurality of columns the axes of which are parallel to the axis of the mounting member and a second plurality of columns the axes of which extend perpendicular to the axis of the mounting member, the columns in one member that are parallel to the axis intersecting the columns in the other member that extend perpendicular to the axis, the columns being arranged such that a moment force imposed on the mount is accommodated by bending of at least some of the columns while vertical, lateral and torsional forces imposed on the mounting member are accommodated by compression or tension in at least some of the columns.
