Abstract

What is described is a joint arrangement for the articulated connection of two segments of a patient bed, with two joint parts (36, 38), each of which is connected rigidly to one of the segments and which are pivotable relative to one another about a common joint axis (64) by means of a shaft journal (46), the joint parts (36, 38) carrying, in each case on at least one of their faces confronting one another axially, blocking faces (60) intended for bearing against one another, and the joint parts (36, 38) being capable of being tensioned axially relative to one another by means of a tensioning mechanism (46, 54, 50), and the blocking faces (60) lying in each case at least approximately in a plane containing the joint axis (64).

Claims

1. A joint arrangement for the articulated connection of two segments of a patient bed, with two joint parts, each of which is connected rigidly to one of the segments and which are pivotable relative to one another about a common joint axis by means of a shaft journal, the joint parts carrying, in each case on at least one of their faces confronting one another axially, blocking faces intended for bearing against one another, and the joint parts being capable of being tensioned axially relative to one another by means of a tensioning mechanism, wherein the blocking faces lie in each case at least approximately in a plane containing the joint axis.

2. The joint arrangement according to claim 1, wherein the joint parts carry, on their faces confronting one another, a toothing with a sawtooth profile.

3. The joint arrangement according to claim 1, wherein one of the joint parts is designed as a fork which can be slipped radially onto the shaft journal connected to the other joint part, and in that the shaft journal carries a securing element which projects radially from it and which is dimensioned such that it closes the fork aperture remaining after the fork has been pushed onto the shaft journal.

4. The joint arrangement according to claim 3, wherein the securing element is mounted freely rotatably on the shaft journal.

5. The joint arrangement according to one of claim 1, wherein, on one of the joint parts, a disengageable locking element is arranged, which, in at least one predeterminable pivoting position of the two joint parts, comes into effective engagement with the other joint part in each case, in order to prevent a relative movement of the joint parts at least in the direction of movement blocked by the blocking faces.

6. The joint arrangement according to one of claim 1, wherein the shaft journal is designed as a tie rod of the tensioning mechanism, which is connected at one axial end to a stop supported on one of the joint parts.

7. Joint The joint arrangement according to claim 6, wherein the tensioning means comprises an eccentric lever articulated on the shaft journal.

8. The joint arrangement according to claim 6, wherein the tensioning means comprises a screw grip which is in threaded engagement with the shaft journal.
