主权项

1. A base structure for supporting a patient support structure above a floor, the base structure comprising:
an end support supported on the floor at a first end and comprising a second end above the first end; a rotator member rotatably coupled with the second end of the end support; and a connection subassembly comprising a first connection end and a second connection end opposite the first connection end, the connection subassembly releasably coupled with an end of the patient support structure between the first and second connection ends via a first removable pin, the first connection end releasably coupled with the rotator member via a cooperating arrangement between a second removable pin and the rotator member, the second removable pin extending through the rotator member and the first connection end of the connection subassembly, wherein a cylindrical member extending generally parallel with the second removable pin and extending laterally at least partially through the connection subassembly is configured to restrict movement of at least a portion of the connection subassembly to a single degree of freedom.
