Abstract: A profiled rail system (1) is used for bridging floorcovering transitions, ends or staircase edges. The profiled rail system (1) has a base profile (2) and a covering profile (3). The base profile (2) has at least one vertical leg (6), on which an inner shell (9) of a rotary joint (10) is provided. This rotary joint (10) supports the covering profile (3) such that it can be pivoted. For this purpose, two webs (11) oriented downward are provided on the covering profile (3) and, in order to form an outer shell of the rotary joint (10), have at least two partly cylindrical inner contours (12) which lie one above another. These inner contours (12) are formed so as to match the inner shell (9) of the rotary joint (10). In this way, step by step adjustability of the covering profile (3) is implemented. The rotary joint (10) can be clicked as desired into respectively one of the partly cylindrical inner contours (12).
