Device for covering joints

摘要

The edging cover has a profiled base rail (12) with a horizontal fixing arm (18) and an upright support arm (20), and a profiled cover rail (14) with horizontal cover arm (28,30) and downward pointing support arm (32). An articulated head (22) at the top end of the base rail support arm or bottom end of the cover rail support arm (32) has a circular cylindrical outer face broken by a longitudinal groove (26) and having a circumferential angle greater than 180 deg. which is coaxial with the articulated axis. The articulated socket (32) has two thin-walled mirror-symmetrical curved walls (34,36) with a circumferential gap between the ends whose width is less than the diameter of the articulated head. The inner faces of the curved walls and an interconnecting intermediate face form a cohesive cylindrical face whose circumferential angle is greater than 180 deg.
