Abstract
Abstract The curtain rod acts as shield concealing the runners and the upper edge of the curtain. The runners are guided by edges of slots in the inner and outer rod sections by means of grooves. The grooves receive the slot edges of the inner as well as outer rod section of the telescoping curtain rod only at the area of transition between inner and outer rod section. The runners glide back and forth between the outer rod section and the inner rod section without impinging at any place. This is due to the design according to which mentioned edges of the slots cooperate exclusively with only one each of two grooves present in the runners, each groove alocated to one respective guiding edge.
