Claim:
Profile-rail system for at least one of bridging expansion joints, recesses, and as an edge closure in respect of flooring elements which are held one against the other by undercut tongue and groove profilings such that they can be clicked in place, said profile-rail system having at least two mutually telescopable profiled rails, at least one of which having a surface-near web, which intrudes displaceably into a receiving pocket in the opposite profiled rail, at least one of said profiled rails having a profiling on the end side facing the flooring elements, said profiling containing at least one of an undercut tongue and a groove which is configured to fit the tongue and groove profiling of the flooring elements to enable the profiled rails to be connected to the flooring elements on the end face by tilting and pressing of the tongue into the opposite groove, at least one of said profiled rails comprising multiple downwardly extending webs and said profile-rail system having base rails comprising multiple vertical webs, at least one of said base rails being positioned below said receiving pocket, said multiple downwardly extending webs of said profile rails being detachably mounted on said base rails in different respective positions, namely in a first position, wherein said downwardly extending webs are bearing against said vertical webs, and in a second position, wherein said downwardly extending webs are not bearing against said vertical webs, so as to realize the function of a height-adjustability of said receiving pocket and surface-near web.
