摘要

The receiver for a curved dome (2) with a cap (1) has a base (3) with a lower support face (4) and an upper receiving face (5) with two parallel grooves (6,7) spaced (A) from each other. The spacing is less than the width of the dome in its free form. The grooves can be positioned at the lower edges of stop faces (8,9) on the upper receiving face.
