Abstract: The outer rail retains two lateral screw webs of an intermediate rail to construct a base for wall plate covering. Two retention devices are disposed oppositely on respective inner sides of each retention web for retaining a respective screw web of the intermediate rail. Each retention device including an abutment part, which extends inwards from the inner side of the retention web such as to form an abutment surface for the respective screw web when the latter is positioned to be retained in the retention device, and extends from the abutment part into a locking part, which extends at an angle to the abutment part and at a distance from the respective retention web. Each locking part comprising a first resilient locking pin adapted to lock a first screw web configuration and a second, separate resilient locking pin adapted to lock a second screw web configuration, the first and second screw web configurations being pre-defined and different from each other.

Abstract: The present invention concerns a sectional rail system which is constructed with the known outer rails with U-shaped cross-section and intermediate rails with C-shaped cross-section, and which is peculiar in that each of the retention means of the outer rail includes at least one stop pin which is disposed close to the inner side of the screw web of an outer rail, preferably two stop pins disposed opposite each other close to the inner side of the screw webs of the outer rail, where each stop pin furthermore is provided with a support flange for supporting an end part of the reinforcement web of the intermediate rail. The fastening means of the outer rail may thus include one, two or more stop pins, and one or more resilient lock pins. Hereby may be achieved provision of a tool-free assembly method for the sectional rail system and that by screwing on plate covering close to the edge part of the intermediate rail, it is avoided that the screw web and the associated reinforcement web “capsize”.
