Abstract
Abstract A specially designed beveled edge (26) guides tile interlocks (14) into place and holds them in place during assembly, thereby facilitating ease and speed of interlocking tile (10) assembly for tight fitting interlocks which actually lock contiguous tiles together. Assembly time for an entire surface using such interlocking tiles is greatly reduced in comparison to comparable prior art interlocking tiles with no diminution in interlocking quality or tile wear.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
234 words
A quick assembly, interlocking tile, which comprises a. an edge region having a periphery having a bottom, said edge region having four corners, the periphery of said edge region provided with four corner interlocks extending from each of the four corners of said edge region and a plurality of central interlocks extending from said edge region between said corner interlocks to interconnect and lock said tile with contiguous tiles whereby a surface covering is constructed, b. said central interlocks comprising central projecting elements and alternating slots in the form of inversions of the central projecting elements formed thereby, c. each of said corner interlocks comprising a right corner projecting element, an alternating slot in the form of an inversion of the central projecting elements formed between the right corner projecting element and the central projecting elements, and a left corner projecting element comprising a square knob having sides of fixed length, said square knob positioned at a distance from said corner equal to the square knob's side's length, d. said central projecting elements and right corner projecting elements interlocking with a contiguous tile's adjacently positioned slots in the form of the inversion of a central projecting element, e. said edge region including a bevel at the bottom of the periphery of the edge region to facilitate the assembly of contiguous interlocking tiles, f. said tile including an inner region integral with said edge region.
Claim 2
Dependent Claim
234 words
A quick assembly, interlocking tile, which comprises a. an edge region having a periphery having a bottom, said edge region having four corners, the periphery of said edge region provided with four corner interlocks extending from each of the four corners of said edge region and a plurality of central interlocks extending from said edge region between said corner interlocks to interconnect and lock said tile with contiguous tiles whereby a surface covering is constructed, b. said central interlocks comprising central projecting elements and alternating slots in the form of inversions of the central projecting elements formed thereby, c. each of said corner interlocks comprising a right corner projecting element, an alternating slot in the form of an inversion of the central projecting elements formed between the right corner projecting element and the central projecting elements, and a left corner projecting element comprising a square knob having sides of fixed length, said square knob positioned at a distance from said corner equal to the square knob's side's length, d. said central projecting elements and right corner projecting elements interlocking with a contiguous tile's adjacently positioned slots in the form of the inversion of a central projecting element, e. said edge region including a bevel at the bottom of the periphery of the edge region to facilitate the assembly of contiguous interlocking tiles, f. said tile including an inner region integral with said edge region.
Claim 3
Dependent Claim
179 words
The quick assembly interlocking tile of claim 1 further characterized by a. said central projecting elements consisting of two 180 degree oppositely directed incurvate regions extending from said edge region, two equidistant oppositely directed straight regions, one extending from each of said incurvate regions and parallel to said edge region, two 180 degree curved regions directed towards each other extending from said equidistant straight regions, said curved regions being connected by a straight line extending between said curved regions and alternating slots in the form of inversions of the central projecting elements formed thereby, b. said right corner interlocks comprising right corner projecting elements consisting of a 180 degree right corner incurvate region extending from said edge region, a right corner straight region parallel to said edge region extending from said right corner incurvate region, one 180 degree right corner curved region directed towards the right corner of said edge region extending from said right corner straight region, said right corner curved region being connected to the right corner of said edge region by a right corner straight line.
Claim 4
Dependent Claim
18 words
The quick assembly, interlocking tile of claim 2 further characterized by the tile being made of polyvinyl chloride.
Claim 5
Dependent Claim
35 words
The quick assembly, interlocking tile of claim 3 further characterized by the tile having a thickness of one quarter of an inch and the bevel having a thickness of three thirty seconds of an inch.
