Joint arrangement for the connection of two segments of a patient bed
First Claim
1. A joint arrangement comprising:
- a first joint part having two mutually parallel portions with substantially flat opposed faces defining between them a gap, one of the opposed faces including a first sawtooth profile extending around a joint axis substantially perpendicular to the opposed faces;
a shaft journal extending across the gap between the two parallel portions along the joint axis of said first joint part;
a tensioning mechanism operatively connecting the two parallel portions of said first joint part, and actuable via said shaft journal to tension together the two parallel portions; and
a second joint part formed as a flat ring with a radial slot and having a side face perpendicular to an axis of the flat ring and formed with a second sawtooth profile extending around the axis of the flat ring;
wherein said second joint part can be assembled into the gap of said first joint part by slipping the radial slot of said second joint part over said shaft journal with the second sawtooth profile facing the first sawtooth profile such that said second joint part is rotatable within the gap about said shaft journal, and such that actuating said tensioning mechanism engages the first sawtooth profile formed on said first joint part with the second sawtooth profile formed on said second joint part for restraining said second joint part relative to said first joint part.

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).

9. A joint arrangement comprising:
-
a first joint part having two mutually parallel portions with substantially flat opposed faces defining between them a gap, one of the opposed faces including a first sawtooth profile extending around a joint axis substantially perpendicular to the opposed faces; a shaft journal extending across the gap between the two parallel portions along the joint axis of said first joint part; a tensioning mechanism operatively connecting the two parallel portions of said first joint part via said shaft journal, and actuable to tension together the two parallel portions of said first joint part; a second joint part formed as a flat ring with a radial slot and having a side face formed with a second sawtooth profile extending around the axis of the flat ring and assembled into the gap of said first joint part by slipping the radial slot of said second joint part over said shaft journal in an unlocked position such that said second joint part is rotatable within the gap about said shaft journal, and such that actuating said tensioning mechanism can engage the first sawtooth profile formed on said first joint part with the second sawtooth profile formed on said second joint part for restraining said second joint part relative to said first joint part in a locked position; and a disengageable locking element arranged on one of said first joint part or said second joint part, which in an engaged position extends into the gap of said first joint part to engage the other of said first joint part or said second joint part to prevent a relative movement of the joint parts in at least one direction of rotation about the joint axis. - View Dependent Claims (10, 11, 12, 13)
