The guides (5,6) each have two separate and thus relatively to each other angled parts, and the flat rail on being driven through the guides is bent in its plane and crossways to its longitudinal direction to arc form. - An extension vane to the ground fixture is at one end fixable to the long part upper section (1). Its other end has a guide corresp. to the long part guides for a flat rail (2). |
