Abstract

The invention relates to a patient support comprising supporting elements which are connected at facing ends by means of a single coupling rod which is pivotably connected to the ends of the elements. Each element is also pivotably connected, at a location which is situated at some distance from the end connected to the coupling rod, to one of two parallel shafts mounted on a frame. During pivoting of the supporting elements, the length of the supporting surface available for a patient changes, so that a supported patient virtually does not slide at all across the supporting elements during this pivoting movement.

Claims

1. A patient support comprising:

a frame;

first and second parallel shafts mounted on the frame;

first and second supporting elements each having first and second ends, said first supporting element pivotably connected to said first shaft and said second supporting element pivotably connected to said second shaft such that the second end of one supporting element is adjacent the second end of the other supporting element in at least one position of the patient support, the pivotable connections being at distances away from the second ends; and

a single coupling rod having two ends, each end pivotably connected to one of the second ends of the supporting elements.

2. A patient support as claimed in claim 1, CHARACTERIZED IN THAT:

the support further comprises a leg support having an end connected to the first shaft; and

the first supporting element is pivotably connected to the first shaft at its first end.

3. A patient support as claimed in claim 1, CHARACTERIZED IN THAT the support further comprises:

a leg support having a journal, the first supporting element connected to the first shaft by means of the leg support, the leg support being pivotably connected to the first end of the first supporting element;

a guide for the leg support journal; and

a second coupling rod having two ends, one end pivotably connected to the leg support and the other end pivotably connected to the first shaft.

4. A patient support comprising:

a frame;

a first supporting element having first and second end and having a supporting surface, said supporting surface having a second end which is at a preselected distance from the second end of the supporting element, said first supporting element being pivotably connected to said frame around a first axis;

a second supporting element having first and second ends and having a supporting surface with first and second ends, said second supporting element being pivotably connected to said frame around a second axis which is parallel to the first axis such that the second end of the supporting surface of the second supporting element is adjacent the second end of the supporting surface of the first supporting element in at least one position of the patient support, the pivotal connections to the supporting elements being away from these second ends, and

a single coupling rod having two ends, each end pivotably connected to one of the second ends of the supporting elements.
