Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
130 words
A surface covering installation comprising, in combination: a structure including at least one surface comprising at least one access cover area for access to an area behind or beneath said surface; and at least one strip of surface covering material relatively wider than the access cover area with a first portion at one side of said access cover area cemented to the construction surface and a second portion at another side of the access cover area opposite to the first mentioned access cover area side secured to the construction surface by a release adhesive; so that the strip of surface covering material may be secured to overlie the structure surface including the access cover area to form at least one liftable flap of covering material over said access cover area.
Claim 2
Dependent Claim
130 words
A surface covering installation comprising, in combination: a structure including at least one surface comprising at least one access cover area for access to an area behind or beneath said surface; and at least one strip of surface covering material relatively wider than the access cover area with a first portion at one side of said access cover area cemented to the construction surface and a second portion at another side of the access cover area opposite to the first mentioned access cover area side secured to the construction surface by a release adhesive; so that the strip of surface covering material may be secured to overlie the structure surface including the access cover area to form at least one liftable flap of covering material over said access cover area.
Claim 3
Dependent Claim
27 words
The surface covering installation as claimed in Claim 1, in which the liftable flap of covering material has a hinge edge and at least one lift edge.
Claim 4
Dependent Claim
22 words
The surface covering installation as claimed in claim 2, in which the release adhesive comprises at least one pressure sensitive adhesive tape.
Claim 5
Dependent Claim
43 words
The surface covering installation as claimed in claim 3, in which the structure surface is a floor, or wall surface, or the like, and at least one coating of sealer is placed on the floor to underlie the lift edge of the flap.
Claim 6
Dependent Claim
28 words
The surface covering installation as claimed in claim 4, in which a double-faced adhesive tape is placed between the sealer coat and the lift edge of the flap.
Claim 7
Dependent Claim
24 words
The surface covering installation as claimed in claim 5, in which a tape having a smooth outer face is positioned at the lift edge.
Claim 8
Dependent Claim
32 words

Claim 10
Dependent Claim
156 words
The surface covering installation as claimed in claim 7, in which the floor, or the like, is made of concrete and the strip of covering material is an elongated strip with a pair of substantially parallel sides running in the direction of the trench with the trench intermediate the strip covering material sides, with said flap hinge edge portion between a first side of the strip material and a first side of the trench, said strip being cemented to the floor between said first side and said hinge flap edge portion, said lift edge flap portion being formed by a cut through the strip material running longitudinally between a second edge of the strip material and a second edge of the trench and said adhesive securing means comprising a tape strip on the lift edge portion and the adhesive faces of said double-faced strip of tape between sealer coat and said lift edge of the flap.
Claim 11
Dependent Claim
25 words
The surface covering installation as claimed in claim 9, in which the strip of coVering material is comprised of carpeting having a sponge bonded base.
Claim 12
Dependent Claim

The surface covering installation as claimed in claim 8, in which the floor, or the like, is made of concrete and the strip of covering material completely overlies the access cover with the flap being relatively larger than the access cover and having a perimeter surrounding the access cover formed by at least one hinge edge and at least one lift edge, said strip material being cemented to the floor at said hinge flap edge, said lift edge being formed by at least one cut through the strip material and said adhesive securing means comprising a strip of tape adhesive on the lift edge portion and the adhesive faces of said double-faced strip overlying said sealer coat.
Claim 13
Dependent Claim
34 words
The surface covering installation as claimed in claim 11, in which the flap is in the form of a polygon with the hinge forming one side and the lift edge forming the other side.
Claim 14
Dependent Claim
25 words
