Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
224 words
A prefabricated wall element for interior walls of buildings having subfloors over which finish floors are installed, comprising, a finish floor, a frame structure consisting of mutually adjustable parts on each side of which a cover plate having sufficient inherent thickness is attached, at least that portion of said frame structure intended to be adjacent the subfloor being arranged backwardly in relation to the edges of said cover plates so that free edges of said cover plates project beyond said portion of said frame structure on both sides, and a height adjustment for adaptation of said wall element to various room heights, said height adjustment comprising at least one adjusting screw guided with clearance in a bore piercing said portion of said frame structure between said free edges of said cover plates and supported by a screw head on said subfloor on which said wall element is to be erected, and a nut associated with said screw and non-rotatably supported on said frame structure between said free edges of said cover plates, said screw having a collar accessible for adjustment of the screw by a wrench, the arrangement being such that said free edges of said cover plates extend below the level of a finish floor after installation thereof, thereby eliminating the need for cover strips along the lower edge of said wall element.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
56 words
The wall element claimed in claim 1, including at least one leveling piece inserted beneath said frame structure in a space between said projecting free edges, said leveling piece being provided with at least one passage bore for said adjusting screw, said associated nut being non-rotatably attached onto one of the frame structure and leveling piece.
Claim 4
Dependent Claim
44 words
The wall element claimed in claim 2, wherein said nut is plate-shaped and is provided with prong-like projections or clamps for insertion into one of the frame structure and the leveling piece, said projections or clamps being provided in corner zones of the plate.
