In a patient bed system, comprising a patient bed, a support column for supporting the bed and a trolley for transporting the bed, the bed having arranged on it first coupling elements (22) which are intended for selective connection to second or third coupling elements (24, 26) on the support column and on the trolley respectively, locking means (60, 62) being provided on at least one of the coupling elements, in order to lock the first coupling elements (22) alternatively to the second or third coupling elements (24, 26) when the bed is coupled to the support column or to the trolley (16), the locking means have at least one locking element (60, 62) which is arranged adjustably on one of the coupling elements (22, 24, 26) and which, in the engagement position of two coupling elements (22, 24, 26), engages into a clearance (76, 82) of the coupling element adjacent in each case, the coupling elements having formed on them control cams (88), by means of which, during the operation of transferring the bed from the support column onto the trolley, or vice versa, the locking element (60, 62) is shifted positively into the clearance or is shifted out of the latter.
