Abstract: The Profiled rail system (1) serves for bridging expansion joints, cavities and as an edging of floor coverings (3). System (1) has at least one web (9) aligned substantially parallel to the floor covering (3), which web (9) engages displaceably in a pocket (10). Pocket (10) is formed by a cover plate (13) overlapping the web (9) and a base plate (14) under the web (9). Pocket (10) is configured in at least two parts (11, 12). The first part (11) forms cover plate (13). The second part (12) forms base plate (14). The first part (11) and the second part (12) are held together. In a first embodiment, a undercut web (20) holds the parts together by a click connection. In a second embodiment, the parts are held together by at least one screw (18).

Abstract: A floor profile arrangement is provided, in particular for bridging a joint between adjacent floor coverings, with a base profile, a covering profile with at least one sideways projecting covering wing, and a web arrangement as a connection between the base profile and the covering profile, and with an articulation arrangement, the articulation arrangement consisting of an articular cavity disposed on the base profile or the covering profile and an articulation element formed on the lower or on the upper edge of the pivoting web arrangement.

Abstract: The profile-rail system (1) serves for bridging expansion joints. It is held by means of undercut tongue and groove profilings (3, 4) such that it can be held in a click-in arrangement against flooring elements. In order to obtain a width adjustment and an adjustment to movements of the floor covering, the profile-rail system (1) has at least two telescopable profiled rails (5, 6). These profiled rails (5, 6) can be held against the flooring elements (2) exclusively on the end face.
