Abstract
Abstract Disclosed is an access floor system with deep pile carpet covered panels. The deep pile fibers from adjacent panels intermingle with each other to visually obscure the cracks between the panels. Disclosed is a tool and method for inserting or reinserting such panels into the floor system without pinching carpet pile between the panel edges. Disclosed is a floor system having service conduits running between adjacent panels but being visually undetectable due to the uniform appearance of the deep pile carpet covering.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A method of assembling a surface covering having a plurality of covering elements, each element having a face covered with pile fibers of a type that extend beyond the edges of said element unless restrained, comprising the steps of: applying a pile restraining tool at the free ends of the pile at an edge of an installed element that is adjacent to the location wherein an additional element is to be installed, said pile fibers extending forwardly of said edge and into said location to a first position and said tool being applied to said fibers at said first position, manipulating said tool rearwardly in a direction away from said location and said first position to a second position slightly inwardly of said installed element edge so as to restrain said pile and prevent it from extending into said location, and inserting said additional element into said location such that said restrained pile is prevented from being pinched between adjacent elements during said assembling.
Claim 2
Independent Claim
164 words
A method of assembling a surface covering having a plurality of covering elements, each element having a face covered with pile fibers of a type that extend beyond the edges of said element unless restrained, comprising the steps of: applying a pile restraining tool at the free ends of the pile at an edge of an installed element that is adjacent to the location wherein an additional element is to be installed, said pile fibers extending forwardly of said edge and into said location to a first position and said tool being applied to said fibers at said first position, manipulating said tool rearwardly in a direction away from said location and said first position to a second position slightly inwardly of said installed element edge so as to restrain said pile and prevent it from extending into said location, and inserting said additional element into said location such that said restrained pile is prevented from being pinched between adjacent elements during said assembling.
Claim 3
Dependent Claim
31 words
The method of claim 1 including the additional steps of removing said tool and fluffing said pile so that the fibers from adjacent elements merge to visually obscure the joints therebetween.
Claim 4
Independent Claim
173 words
A method of assembling an access floor system with floor panels having the upper surface thereof covered with a deep pile carpet, the pile fibers of which are of the type that extend beyond the edges of said panels unless restrained, comprising the steps of: applying a pile restraining tool at the free ends of the carpet pile at each edge of installed panels that is adjacent to the location wherein an additional panel is to be installed, said pile fibers extending forwardly of said edges and into said location to first positions and each of said tools being applied to said fibers at said first positions, manipulating all of said tools rearwardly in a direction away from said location and said first positions to second positions slightly inwardly of said installed panel edges so as to restrain said carpet pile and prevent it from extending into said location, and inserting said additional panel into said location such that said restrained pile is prevented from being pinched between adjacent panels during said assembling.
Claim 5
Independent Claim
173 words
A method of assembling an access floor system with floor panels having the upper surface thereof covered with a deep pile carpet, the pile fibers of which are of the type that extend beyond the edges of said panels unless restrained, comprising the steps of: applying a pile restraining tool at the free ends of the carpet pile at each edge of installed panels that is adjacent to the location wherein an additional panel is to be installed, said pile fibers extending forwardly of said edges and into said location to first positions and each of said tools being applied to said fibers at said first positions, manipulating all of said tools rearwardly in a direction away from said location and said first positions to second positions slightly inwardly of said installed panel edges so as to restrain said carpet pile and prevent it from extending into said location, and inserting said additional panel into said location such that said restrained pile is prevented from being pinched between adjacent panels during said assembling.
Claim 6
Dependent Claim
31 words
The method of claim 3 including the additional steps of removing said tools and fluffing said pile so that the fibers from adjacent carpeted panels merge to obscure the joint therebetween.
