Abstract
Abstract A connecting structure of floor mat sections particularly adapted for public foyer walking areas, the connecting sections being formed to be unitary of plastic material, certain of said sections having terminal portions at each side thereof having axial bores therein coextensive therewith, said bores having slots therethrough at the outer side thereof and alternate of said sections having terminal portions at each side thereof having outwardly extending web portions having outer edges adapted to be received and retained within an adjacent of said bores for interconnection of said sections, said webs having medial thickness such as to pass through said slots, said sections having tread surfaces and underlying support surfaces, said surfaces being reversible.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A floor covering mat structure consisting of interconnected sections, having in combination a first section having a central body portion and unitary therewith lateral terminal body portions at each side thereof, all formed of a plastic material, said first section having a self formed ribbed tread surface, said lateral terminal portions each having an axial bore, a slot extending outwardly laterally of each of said bores, a second section having a central body portion and unitary therewith lateral terminal body portions at each side thereof, all formed of a plastic material, said second section having a self formed ribbed tread surface, said last mentioned lateral terminal portions each having a web extending outwardly laterally thereof, each of said webs having an outer edge portion disposed within the bore of an adjacent body lateral terminal portion and retained therein, each of said webs having a medial thickness such as to extend through the slot of the bore of an adjacent body terminal portion, and the underlying surface portions of said first and said second sections forming an underlying support.
Claim 2
Dependent Claim
178 words
A floor covering mat structure consisting of interconnected sections, having in combination a first section having a central body portion and unitary therewith lateral terminal body portions at each side thereof, all formed of a plastic material, said first section having a self formed ribbed tread surface, said lateral terminal portions each having an axial bore, a slot extending outwardly laterally of each of said bores, a second section having a central body portion and unitary therewith lateral terminal body portions at each side thereof, all formed of a plastic material, said second section having a self formed ribbed tread surface, said last mentioned lateral terminal portions each having a web extending outwardly laterally thereof, each of said webs having an outer edge portion disposed within the bore of an adjacent body lateral terminal portion and retained therein, each of said webs having a medial thickness such as to extend through the slot of the bore of an adjacent body terminal portion, and the underlying surface portions of said first and said second sections forming an underlying support.
Claim 3
Dependent Claim
197 words
A floor covering mat structure consisting of interconnected sections, having in combination an elongated body portion, a terminal portion at each side of said body portion unitary therewith, and said body and terminal portions being formed of a plastic material, an axial bore extending through each of said terminal portions, a slot extending outwardly laterally of each of said bores, a second elongated body portion, a terminal portion at each side of said second mentioned body portion unitary therewith and said body and terminal portions being formed of a plastic material, a web extending outwardly laterally of each of said second mentioned terminal portions, each of said webs having an outer edge compatible with and disposed within an adjacent of said bores and retained therein, each of said webs having a medial thickness such as to extend through an adjacent of said slots, said first and second mentioned body portions each having self formed upstanding ribbed tread surface portions, said body portions each having an underlying surface portion like its respective overlying tread surface portion, said underlying surface portions each forming an underlying support, and said underlying surface portions being interchangeable with said overlying tread surface portions.
Claim 4
Dependent Claim
197 words
A floor covering mat structure consisting of interconnected sections, having in combination an elongated body portion, a terminal portion at each side of said body portion unitary therewith, and said body and terminal portions being formed of a plastic material, an axial bore extending through each of said terminal portions, a slot extending outwardly laterally of each of said bores, a second elongated body portion, a terminal portion at each side of said second mentioned body portion unitary therewith and said body and terminal portions being formed of a plastic material, a web extending outwardly laterally of each of said second mentioned terminal portions, each of said webs having an outer edge compatible with and disposed within an adjacent of said bores and retained therein, each of said webs having a medial thickness such as to extend through an adjacent of said slots, said first and second mentioned body portions each having self formed upstanding ribbed tread surface portions, said body portions each having an underlying surface portion like its respective overlying tread surface portion, said underlying surface portions each forming an underlying support, and said underlying surface portions being interchangeable with said overlying tread surface portions.
Claim 5
Dependent Claim
21 words
The structure of claim 2, wherein said tread surface of each of said body portions extending upon their respective terminal portions.
Claim 6
Dependent Claim
23 words
