Abstract
Abstract A perforate plastic floor mat and friction device having an upper surface of parallel narrow strips spaced apart approximately their own width, and a lower surface of more widely spaced strips underlying and crossing the upper strips to provide rectangular apertures, and plastic connectors having locking portions fitting into said apertures and engaging the upper and lower strips to lock together smaller such mats into larger ones.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
a. A plastic floor mat comprising b. a first series of parallel plastic top strips spaced apart a distance substantially equal to their own width, c. a second series of parallel plastic bottom strips underlying and crossing said top strips and spaced apart at least twice the distance separating the top strips, the strips of the two series being integrally molded together at all points where they cross, d. a series of locking links fastened to a first such mat near one edge thereof for joining said first mat to a second such mat at a common edge to make a larger mat, said links having a connecting strip extending between said two mats and having a narrow latching member at one end lying in the space between two adjacent ones of said top strips and overlying two adjacent bottom strips with the connecting strip of said link lying under at least one of said first top strips.
Claim 2
Dependent Claim
158 words
a. A plastic floor mat comprising b. a first series of parallel plastic top strips spaced apart a distance substantially equal to their own width, c. a second series of parallel plastic bottom strips underlying and crossing said top strips and spaced apart at least twice the distance separating the top strips, the strips of the two series being integrally molded together at all points where they cross, d. a series of locking links fastened to a first such mat near one edge thereof for joining said first mat to a second such mat at a common edge to make a larger mat, said links having a connecting strip extending between said two mats and having a narrow latching member at one end lying in the space between two adjacent ones of said top strips and overlying two adjacent bottom strips with the connecting strip of said link lying under at least one of said first top strips.
Claim 3
Dependent Claim
158 words
A. A plastic floor mat comprising b. a first series of parallel plastic top strips spaced apart a distance substantially equal to their own width, c. a second series of parallel plastic bottom strips underlying and crossing said top strips and spaced apart at least twice the distance separating the top strips, the strips of the two series being integrally molded together at all points where they cross, d. a series of locking links fastened to a first such mat near one edge thereof for joining said first mat to a second such mat at a common edge to make a larger mat, said links having a connecting strip extending between said two mats and having a narrow latching member at one end lying in the space between two adjacent ones of said top strips and overlying two adjacent bottom strips with the connecting strip of said link lying under at least one of said first top strips.
Claim 4
Dependent Claim
158 words
A. A plastic floor mat comprising b. a first series of parallel plastic top strips spaced apart a distance substantially equal to their own width, c. a second series of parallel plastic bottom strips underlying and crossing said top strips and spaced apart at least twice the distance separating the top strips, the strips of the two series being integrally molded together at all points where they cross, d. a series of locking links fastened to a first such mat near one edge thereof for joining said first mat to a second such mat at a common edge to make a larger mat, said links having a connecting strip extending between said two mats and having a narrow latching member at one end lying in the space between two adjacent ones of said top strips and overlying two adjacent bottom strips with the connecting strip of said link lying under at least one of said first top strips.
Claim 5
Dependent Claim
24 words
The invention according to claim 1, e. said link being integrally molded at the other end of said connecting strip to said first mat.
Claim 6
Dependent Claim
57 words
The invention according to claim 1, e. there being a series of such links, each having two such narrow latching members joined by its connecting strip, said strip being narrower in width than the space between two adjacent ones of said second series of strips, and of no greater thickness than a strip of said second series.
Claim 7
Dependent Claim
78 words
The invention according to claim 1, e. and a second series of locking links joining two such mats sidE-by-side with the top strips of the two mats aligned with each other, f. each of said second series of links having a connecting strip lying between two adjacent top strips and over the adjacent parallel end bottom strips of the two mats, and locking tabs at the ends of said connecting strip each extending beneath two adjacent top strips.
Claim 8
Dependent Claim
119 words
The invention according to claim 1, e. and an attachable edge ramp strip having a tapered cross section joined to said mat along an edge thereof to provide a feathered ramp edge for the mat, f. said ramp strip, on the side adjoining the mat, being of the same thickness as the mat and including a narrow strip of the same width as the top strips of the mat and spaced from the body of the ramp strip by a space equal to that between adjacent top strips of the mat, and connected to the body of the ramp strip by a series of short bottom strips similar to, and spaced apart like, the bottom strips of the mat.
Claim 9
Dependent Claim
40 words
The invention according to claim 5, g. said ramp strip tapering in cross section from the thick base portion to a feather edge, and a longitudinally extending bead on the under side of said ramp strip near said feather edge.
