Abstract
Abstract A resilient strip is provided for self-sealing, self-stabilizing installation in a floor expansion void between a room wall and the edge of the floor. The main body of the extruded resilient strip is generally triangular in cross section with a recessed base adapted to engage the wall side of the expansion void and a truncated apex adapted to seat against the floor side of the expansion void adjacent its upper edge thereby placing the upper and lower sides of the strip in compression transversely thereof. The upper side of the strip preferably includes an integral baseboard flange tapering to a thin wall-hugging edge. No fasteners or adhesives are required for installation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
172 words
A strip for sealing an expansion void between the floor and a room wall comprising: an elongated extruded strip of resilient material of uniform cross section having upper and lower surfaces converging toward one another from a relatively wide wall-engaging lateral side thereof; said wall-engaging side of said strip being recessed and provided with upper and lower ribs extending lengthwise thereof, said upper rib being adapted to seat firmly against the wall adjacent the top of said void and said lower rib being adapted to seat firmly against the wall adjacent the bottom of said void; the opposite relatively narrow lateral side of said strip being provided with at least one rib adapted to seat firmly against the edge of the floor side of said expansion void adjacent but below the upper surface of the floor; and said ribs along the opposite lateral sides of said strip being adapted to cooperate with one another in providing a self-stabilizing generally triangular anchorage effective to lock said strip firmly assembled in said expansion void.
Claim 2
Dependent Claim
172 words
A strip for sealing an expansion void between the floor and a room wall comprising: an elongated extruded strip of resilient material of uniform cross section having upper and lower surfaces converging toward one another from a relatively wide wall-engaging lateral side thereof; said wall-engaging side of said strip being recessed and provided with upper and lower ribs extending lengthwise thereof, said upper rib being adapted to seat firmly against the wall adjacent the top of said void and said lower rib being adapted to seat firmly against the wall adjacent the bottom of said void; the opposite relatively narrow lateral side of said strip being provided with at least one rib adapted to seat firmly against the edge of the floor side of said expansion void adjacent but below the upper surface of the floor; and said ribs along the opposite lateral sides of said strip being adapted to cooperate with one another in providing a self-stabilizing generally triangular anchorage effective to lock said strip firmly assembled in said expansion void.
Claim 3
Dependent Claim
41 words
A sealing strip as defined in claim 1 characterized in that the relatively narrow floor-engaging lateral side of said strip is provided with a plurality of closely spaced ribs seatable against the edge of the floor adjacent the upper side thereof.
Claim 4
Dependent Claim
57 words
A sealing strip as defined in claim 1 characterized in that the floor-engaging lateral side of said strip includes a relatively thin sealing lip along the uppermost edge thereof; said sealing lip projecting laterally outwardly beyond the edge of said floor engaging rib and adapted to lie in sealing contact with the top surface of the floor.
Claim 5
Dependent Claim
22 words
A sealing strip as defined in claim 1 characterized in that the durometer of said resilient material ranges between 40 and 80.
Claim 6
Dependent Claim
46 words
A sealing strip as defined in claim 1 characterized in that, when installed in an expansion void, the portions of said strip adjacent a respective one of said upper and lower surfaces is under compression in planes inclined in opposite directions relative to a horizontal plane.
Claim 7
Dependent Claim
61 words
A sealing strip as defined in claim 1 characterized in that said strip includes a wall-engaging base board flange projecting outwardly from and integral with said upper surface of said strip, said flange having a relatively thin lateral edge remote from said upper surface positioned to lie flush against a room wall when said strip is seated in said expansion void.
Claim 8
Dependent Claim
29 words
A sealing strip as defined in claim 6 characterized in that said wall-engaging base board flange is inclined acutely to the wall surface when installed in said expansion void.
Claim 9
Dependent Claim
32 words
A sealing strip as defined in claim 1 and 6 characterized in that said strip is sufficiently flexible and resilient for snug sealing installation in a curvilinear portion of an expansion void.
