System for Mounting Wall Panels to a Wall Structure

摘要

A system for mounting wall panels to a wall, includes wall panels, each including a main wall panel, and at least two bent end sections with a cut-out section and a wall thickness; and a plurality of main fastening extrusions, each including a base section to be secured to the wall, and two parallel, spaced apart flexible and resilient bent end securing walls extending from the base section, each bent end securing wall including a projection facing the other bent end securing wall, the bent end securing walls spaced apart corresponding to the wall thickness of two bent end sections, such that pressing of the bent end sections into the spacing between the bent end securing walls causes biasing away of the bent end securing walls until the projections engage in respective cut-out sections with the bent end sections being at least in near abutting relation.

主权项

1. A system for mounting wall panels to an existing wall structure, comprising:
a plurality of wall panels, each wall panel including:
a main wall panel, andat least two bent end sections extending at an angle from different edges of said main wall panel, each bent end section including a cut-out section at an inner wall surface thereof, each bent end section having a wall thickness, and each said cut-out section having a holding surface; and a plurality of main fastening extrusions, each fastening extrusion including:
a base section adapted to be secured to the existing wall structure, said base section including at least one base securing wall adapted to be secured by fastening devices to the existing wall structure, andtwo parallel, spaced apart flexible and resilient bent end securing walls extending at an angle from said base section, each said bent end securing wall including a projection at one surface thereof facing the other bent end securing wall, the two bent end securing walls having a spacing corresponding substantially to the wall thickness of two said bent end sections, each said projection has a corresponding holding surface which is engaged by said holding surface of the respective cut-out section when said projection is engaged in the respective said cut-out section to prevent escape of the respective said bent end section, and each said projection has an inclined surface which terminates in the holding surface thereof, andsaid at least one base securing wall of said base section includes a central base securing wall positioned between said bent end securing walls and at least one wing wall coplanar with said central base securing wall and extending outwardly of at least one said bent end securing wall, with openings in at least one of said central base securing wall and said at least one wing wall for insertion of the fastening devices therein,wherein pressing of said bent end sections into said spacing between said bent end securing walls causes said bent end securing walls to be biased away from each other until said projections engage in respective said cut-out sections to lock said bent end sections in said spacing in a manner that outer walls of said bent end sections are at least in near abutting relation with each other, and each said bent end section has a lower end with a beveled surface for engaging with said inclined surface of the respective said projection when said bent end section is pressed into said spacing between said bent end securing walls to cause the respective said bent end securing wall to be biased away from the other bent end securing wall until said projection engages in the respective said cut-out section.
