Abstract

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.

Claims

1. 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 which are intended for selective connection to second or third coupling elements on the support column and on the trolley respectively, locking means being provided on at least one of the coupling elements, in order to lock the first coupling elements alternatively to the second or third coupling elements when the bed is coupled to the support column or to the trolley, wherein the locking means comprise at least one locking element which is arranged adjustably on one of the coupling elements and which, in the engagement position of two coupling elements, engages into a clearance of the coupling element adjacent in each case, and in that the coupling elements have formed on them control cams, by means of which, during the operation of transferring the bed from the support column onto the trolley, or vice versa, the locking element is shifted positively into the clearance or is shifted out of the latter.

2. The patient bed system according to claim 1, wherein the locking element is designed as a two-armed rotatably mounted lever which has control edges which are intended to interact with the control cams and which are arranged on both sides of the fulcrum of the lever.

3. The patient bed system according to claim 2, wherein each first coupling element has arranged on it two locking elements, of which one is intended for locking the first coupling element to the second coupling element and the other is intended for locking the first coupling element to the third coupling element, and in that the control cams are designed for adjusting the locking elements on the second or the third coupling element.
