Profiled rail system

Abstract

A profiled rail system ( 1 ) is used for bridging expansion joints or openings and or as edging of floor coverings ( 5 ). The profiled rail system ( 1 ) has a first ( 2 ) and a second profiled rail ( 3 ) which have mutually overlapping cover legs ( 6 ) being directed towards one another and oriented substantially parallel to the floor covering ( 5 ). The profiled rails ( 2, 3 ) can be displaced with each other. The first profiled rail ( 2 ) has a base leg ( 8 ) which, together with a cover leg ( 6 ) of the first profiled rail ( 2 ) forms a pocket ( 12 ) for receiving a leg ( 6, 8 ) of the second profiled rail ( 3 ). A first stop ( 10 ) is provided on the base leg ( 8 ) of the first profiled rail ( 2 ). The first stop ( 10 ) is an operative connection with a second stop ( 11 ) and the second profiled rail ( 3 ). The stops ( 10, 11 ) limit mutual displacement of the first profiled rail ( 2 ) with respect to the second profiled rail ( 3 ) in an expansion position. In order to realise an easy mounting, in the expansion position the ratio of an overlapping ( 14 ) of the cover legs ( 6 ) of the profiled rails ( 2, 3 ) to a clear height ( 15 ) of the pocket ( 12 ) is less than or equal to 0.5.

1 . Profiled rail system for floor coverings, for at least one of bridging expansion joints, bridging openings and as edging of said floor coverings, wherein said profiled rail system comprising at least one first profiled with and at least one second profiled rail which both have cover legs, said cover legs are directed towards one another, oriented substantially parallel to said floor covering, and are mutually overlapping, wherein said at least one first profiled rail can be displaced with respect to said at least one second profiled rail to an expansion position and said at least one first profiled rail has at least one base leg which, together with said at least one cover leg of said at least one first profiled rail, forms at least one pocket for receiving at least one of said cover leg and said base leg, of said at least one second profiled rail, wherein at least one first stop is provided on said at least one base leg of said at least one first profiled rail, and at least one second stop is provided on said at least one second profiled rail, said at least one first stop being in operative connection with said at lest one second stop hereby limiting mutual displacement of said at least one first profiled rail with respect to said at least one second profiled rail in said expansion position, in said expansion position said cover legs of said at least one first and second profiled rail having an overlapping and said at least one pocket having a clear height, said overlapping to said clear height having a ratio being less than or equal to 0.5. 
     
     
         2 . Profiled rail system according to  claim 1 , wherein said ratio of said overlapping of said cover legs of said first and second profiled rail in said expansion position to said clear height of said at least one pocket is less than or equal to 0.3. 
     
     
         3 . Profiled rail system according to  claim 1 , wherein said ratio of said overlapping of said cover legs of said first and second profiled rail in said expansion position to said clear height of said at least one pocket is less than or equal to 0.2. 
     
     
         4 . Profiled rail system according to  claim 1 , wherein said ratio of said overlapping of said cover legs of said first and second profiled rail in said expansion position to said clear height of said at least one pocket is at least 0.05. 
     
     
         5 . Profiled rail system according to  claim 4 , said ratio of said overlapping of said cover legs of said first and second profiled rail in said expansion position to said clear height of said at least one pocket is at least 0.1. 
     
     
         6 . Profiled rail system according to  claim 1 , wherein said first and second stop have at least one groove and tongue which are designed to fit one another and form a pivot axis for pivoting said at least one first profiled rail relative to said at least one second profiled rail. 
     
     
         7 . Profiled rail system according to  claims 1 , wherein at least one of said cover legs has at least one third stop.
