Abstract

An operating table is shown, which comprises a table column with a column foot (10) and with a column head and also a bed connectable or connected to the column head, the column foot (10) having a floor-side baseplate (12) and a column-side footplate (14), the footplate (14) being mounted rotatably on the baseplate (12) and being secured, with a vertical play, by means of an abutment (24) against being lifted off from the baseplate (12), and at least one clamping cylinder (42) actuated by pressure medium being provided in order to tension the footplate (14) against the abutment (24).

Claims

1. An operating table, comprising a table column with a column foot and with a column head and also a bed connectable or connected to the column head, wherein the column foot has a floor-side baseplate and a column-side footplate, in that the footplate is mounted rotatably on the baseplate and is secured, with a vertical play, by means of an abutment against being lifted off from the baseplate, and in that at least one pressure-actuated clamping cylinder is provided in order to clamp the footplate against the abutment.

2. The operating table according to claim 1, wherein the damping cylinder is arranged on the footplate and, when acted upon by the pressure medium, is supported on the baseplate.

3. The operating table according to claim 1 wherein the abutment is formed by a circular ring which is connected to the baseplate and which surrounds the footplate and at least partially engages over the latter at its outer edge.

4. The operating table according to claim 1, wherein the at least one clamping cylinder can be acted upon by pressure fluid via a foot-actuated pump.

5. The operating table according to claim 4, wherein the line between the pump and the clamping cylinder is connected to a tank for the pressure fluid via a pressure-limiting valve.
