<p>The beds each comprise a frame to support a bed bottom. The frame has a downwardly directed part with a rectangular cross section. The U shaped clamp (1) width at the base of the U-formation exceeds the horizontal width of two bed frames (6) located widthways to each other. The outer parts (7,8) of the U-arms in the unloaded state are less than the horizontal width of the two bed frames. Such outer parts are outwardly bent.</p> |
