摘要

The typical frame element for the bed is essentially L-shaped. It has a thin horizontal portion and a thick vertical portion (2) forming a first upwardly-extending vertical flange. A small second upwardly-extending vertical flange stands on the horizontal portion and the space between the two flanges forms a groove (5) to accommodate a support for a headboard or headrest.
