Outer rail for wall plate covering

摘要

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. Hereby, different screw web configurations can be attached to the same retention web.

1. An outer rail for retaining two lateral screw webs of an intermediate rail to construct a base for wall plate covering,
the outer rail extending in a longitudinal direction and having a U-shaped cross section formed by a transverse connecting part connecting two opposed lateral retention webs, two retention devices being 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 associated 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, each abutment part extending 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 the first screw web configuration being different from the second screw web configuration, each locking pin projecting in an initial, unloaded position towards the locking pin's associated retention web, each locking pin being adapted to resiliently allow for passage of one of said first and second pre-defined screw web configurations such that the screw web during passage pushes the locking pin resiliently towards the locking part, the locking pin after passage resiliently assuming its initial position, such that a screw web corresponding to either of the first and second pre-defined screw web configurations can be attached to each of the retention webs by sliding the screw web past an associated one of the first and second locking pins of each respective retention device, after which the respective locking pin assumes its initial position to retain the respective screw web between the respective locking pin and abutment part.
