Tiltable Patient-Supporting Apparatus and Method of Tilting a Patient-Supporting Apparatus

Abstract

A patient-supporting apparatus includes a lifting apparatus. The lifting apparatus includes an upper part, a lower part, and a lifting linkage. The lifting linkage connects the upper part to the lower part and has at least one scissors-form sub-linkage having a central articulation. A point of rotation of the central articulation is arranged in a displaceable manner such that the upper part may be tilted in a transverse direction.

1 . A patient-supporting apparatus comprising:
 a lifting apparatus comprising:
 an upper part; 
 a lower part; and 
 a lifting linkage that connects the upper part to the lower part, the lifting linkage comprising at least one scissors-form sub-linkage having a central articulation, 
   wherein a point of rotation of the central articulation is arranged in a displaceable manner such that the upper part is tiltable in a transverse direction of the upper part.   
     
     
         2 . The patient-supporting apparatus of  claim 1 , wherein the upper part is configured in the form of a table top. 
     
     
         3 . The patient-supporting apparatus of  claim 1 , further comprising a table top that is arranged on the upper part. 
     
     
         4 . The patient-supporting apparatus of  claim 1 , further comprising two sub-linkages that are arranged one above the other and are connected to connecting articulations so as to form a double scissors structure,
 wherein the central articulation is formed in an upper sub-linkage of the two sub-linkages.   
     
     
         5 . The patient-supporting apparatus of  claim 1 , further comprising two sub-linkages that are arranged one above the other and are connected to connecting articulations so as to form a double scissors structure,
 wherein the central articulation is formed in an upper sub-linkage and a lower sub-linkage of the two sub-linkages.   
     
     
         6 . The patient-supporting apparatus of  claim 1 , further comprising a first scissors arm and a second scissors arm that form the sub-linkage and are connected to one another by the central articulation such that the first scissors arm and the second scissors arm are rotatable about the point of rotation,
 wherein the point of rotation is arranged in a linearly displaceable manner.   
     
     
         7 . The patient-supporting apparatus of  claim 6 , further comprising a slot that is formed in the first scissors arm, the point of rotation of the central articulation being arranged in the slot in a linearly displaceable manner. 
     
     
         8 . The patient-supporting apparatus of  claim 6 , further comprising a drive unit configured to displace the point of rotation in the slot. 
     
     
         9 . The patient-supporting apparatus of  claim 1 , further comprising a first scissors arm and a second scissors arm that form the sub-linkage and are connected to one another by the central articulation such that the first scissors arm and the second scissors arm are rotatable about the point of rotation,
 wherein the central articulation is configured in the form of an eccentric, to rotate the point of rotation eccentrically.   
     
     
         10 . The patient-supporting apparatus of  claim 9 , further comprising a drive unit configured to rotate the eccentric. 
     
     
         11 . The patient-supporting apparatus of  claim 4 , further comprising a drive unit configured to adjust the upper part in height,
 wherein the drive unit acts on one of the connecting articulations.   
     
     
         12 . The patient-supporting apparatus of  claim 11 , wherein the drive unit is configured for a rectilinear movement of the upper part in the vertical direction. 
     
     
         13 . The patient-supporting apparatus of  claim 2 , further comprising a first scissors arm and a second scissors arm that form the sub-linkage and are connected to one another by the central articulation such that the first scissors arm and the second scissors arm are rotatable about the point of rotation,
 wherein the point of rotation is arranged in a linearly displaceable manner.   
     
     
         14 . The patient-supporting apparatus of  claim 13 , further comprising a slot that is formed in the first scissors arm, the point of rotation of the central articulation being arranged in the slot in a linearly displaceable manner. 
     
     
         15 . The patient-supporting apparatus of  claim 13 , further comprising a drive unit configured to displace the point of rotation in the slot. 
     
     
         16 . A method of tilting a patient-supporting apparatus, the patient-supporting apparatus comprising a lifting apparatus comprising an upper part, a lower part, and a lifting linkage that connects the upper part to the lower part, the lifting linkage comprising at least one scissors-form sub-linkage having a central articulation, wherein a point of rotation of the central articulation is arranged in a displaceable manner such that the upper part is tiltable in a transverse direction of the upper part, the method comprising:
 moving the point of rotation of the central articulation such that the upper part is tilted in the transverse direction.
