Claim 8:
9. A base structure for supporting a patient support structure an adjustable height above a floor, the base structure comprising:
a fail-safe table attachment subassembly operably coupling a first end support of the base structure with a first outer end of the patient support structure so as to prevent inadvertent uncoupling of the first outer end of the patient support structure from the first end support, the first end support having a longitudinal axis extending perpendicular with respect to the floor, the fail-safe table attachment subassembly comprising:
a rotation block having an elongate length defined by a central axis positionable transverse to the longitudinal axis of the first end support in a neutral non-rotated orientation and an elongate ladder attachment structure having a longitudinal axis, the rotation block rotatably affixed with the first end support, the elongate ladder attachment structure comprising a first end releasably rotatably coupled with the rotation block and a second end opposite the first end, the first outer end of the patient support structure configured to releasably couple with the elongate ladder attachment structure between the first and second ends of the elongate ladder attachment structure so as to be height adjustable therebetween with respect to the floor, the first end of the elongate ladder attachment structure having a protrusion configured to pivotally engage an open receiving channel formed in the rotation block along the elongate length thereof and at least a portion of the elongate ladder attachment structure rotatable relative to the rotation block toward the first end support and around a structurally fixed pivot axis located in the rotation block so as to attach the elongate ladder attachment structure to the rotation block by engagement with a spring loaded locking mechanism of the rotation block,
wherein the longitudinal axis of the elongate ladder attachment structure is oriented substantially coplanar and perpendicular with respect to the central axis of the rotation block so as to allow the elongate ladder attachment structure to be releasably coupled to the first outer end of the patient support structure between the first end and the second end of the elongate ladder attachment structure.
