Framework of partition walls

Claim 1

A framework for modular partitioning walls, especially modular walls, for a room of a house, the room having a ceiling, floor and walls, comprising: floor, ceiling and wall profiles adapted for fastening to the room ceiling floor and walls in an orientation defining the plane of the partitioning wall, each of the floor, ceiling and wall profiles including a base section, and two flange sections to present a principally U-shaped cross section, said floor and ceiling profiles having similar cross sections with each including a plurality of tongue elements protruding from their respective base section, said tongue elements being positioned between the flanges of their respective ceiling and floor profiles, opposite vertical edges of said tongue elements defining a width of said tongue elements; panel boards presenting opposed vertical surfaces defining a panel board thickness; and upright profiles adapted to run vertically between the floor and ceiling profiles, each of the upright profiles including a base section, and two flange sections to present a principally U-shaped cross section, the respective end sections of the upright profiles being adapted for elastic, telescopic engagement of said tongue elements, the flanges of said upright profiles being generally resilient and spaced apart by a distance just smaller than the width of said tongue elements whereby the ends of said upright profiles are adapted to each resiliently grip a single respective tongue element protruding from the base of the appropriate ceiling and floor profile in a telescoping fit, said tongue elements of said floor and ceiling profiles respectively being generally oriented in a single row and said base sections of said ceiling and floor profiles being clear of protrusions other than said tongue elements such that the end of a respective upright profile is engageable with a desired tongue element upon horizontal motion of said end of said upright profile relative to said desired fixed tongue element, and each vertical edge of said tongue elements being spaced apart a slightly greater distance from the respective flanges of the floor and ceiling profiles than the thickness of the panel boards whereby said end edge sections of said panel boards are received between the upright profiles and the respective flanges of floor and ceiling profiles for abuttable, retaining engagement of the opposed vertical surfaces of said panel boards by said floor and ceiling profile flanges and said upright profiles.
