L shaped supporting device for adjustable crib, has fixing units placed to fix proximal ends of rods at proximal ends of longerons, and comprising cylindrical female fixation surfaces that retain proximal ends of rods and longerons

摘要

The device (1) has rods (2, 3) extending along vertical direction (I-I) between distal ends (2b, 3b) and proximal ends (2a, 3a). Longerons (5, 6) extend parallel to each other along horizontal direction (II-II) among proximal ends (5a, 6a) and distal ends (5b, 6b) of the longerons. Fixing units (7) are placed to fix the proximal ends of the rods at the proximal ends of the longerons. Each fixing unit includes cylindrical female fixation surfaces that retain the proximal ends of the rods and longerons.
