Modular floor tile

A disk shaped modular floor tile includes three sets of a first projection, a second projection, and a third projection wherein the second and third projections of the same set are arranged oppositely to each other; and notches each formed between any adjacent first projection and second projection, any adjacent second projection and third projection, or any adjacent third projection and first projection. The first projection has a convex edge between two adjacent notches. The notch has a concave edge formed continuously with the convex edge. Each of the second projection and the third projection comprises a convex edge formed continuously with the concave edge, a first straight edge formed continuously with the convex edge, and a second straight edge formed continuously between the first straight edge and the concave edge. The second straight edge is at an obtuse angle with respect to the first straight edge.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to floor tiles and more particularly to a modular floor tile.

2. Description of Related Art

A conventional modular floor tile A shaped as a square is shown inFIG. 1and comprises a plurality of notches A1along four edges, and a plurality of projections A2each defined between two adjacent notches A1. Both the notch A1and the projection A2are shaped as a “T”.

Notwithstanding the prior art, the invention is neither taught nor rendered obvious thereby.

SUMMARY OF THE INVENTION

It is therefore one object of the invention to provide a disk shaped modular plastic floor tile comprising three sets of a first projection, a second projection, and a third projection arranged clockwise on an edge wherein the second projection and the third projection of the same set are arranged oppositely to each other; and a plurality of notches each formed between any adjacent first projection and second projection, any adjacent second projection and third projection, or any adjacent third projection and first projection; wherein the first projection has a convex edge formed between two adjacent notches; wherein the notch has a concave edge formed continuously with the convex edge; wherein each of the second projection and the third projection comprises a convex edge formed continuously with the concave edge, a first straight edge formed continuously with the convex edge, and a second straight edge formed continuously between the first straight edge and the concave edge; wherein the second straight edge is at an obtuse angle with respect to the first straight edge; and wherein the obtuse angle between the first straight edge and the second straight edge of the second projection is distal that of the third projection rather than facing each other.

DETAILED DESCRIPTION OF THE INVENTION

Referring toFIGS. 2 to 5, a modular floor tile1in accordance with a first preferred embodiment of the invention comprises the following components as discussed in detail below. The floor tile1is made of plastic and substantially shaped as a disk.

The floor tile1comprises three sets of a first projection13, a second projection14A, and a third projection14B arranged clockwise on an edge in which the second projection14A and the third projection14B of the same set are opposite. Root of each of the first projection13, the second projection14A, and the third projection14B is formed as a neck11. A notch12is formed between any two adjacent first projection13and second projection14A, any two adjacent second projection14A and third projection14B, or any two adjacent the third projection14B and first projection13.

The first projection13has a convex edge131formed between two adjacent notches12. The notch12has a concave edge121formed continuously with the convex edge131. Each of the second projection14A and the third projection14B comprises a convex edge141formed continuously with the concave edge121, a first straight edge142formed continuously with the convex edge141, and a second straight edge143formed continuously between the first straight edge142and the concave edge121, the second straight edge143being at an obtuse angle θ with respect to the first straight edge142. The obtuse angle θ between the first straight edge142and the second straight edge143of the second projection14A is distal that of the third projection14B rather than facing each other.

As shown inFIG. 4specifically, two floor tiles1can be assembled together by fitting the second projection14A and the third projection14B of one floor tile1into the notches12of the other floor tile1.

As shown inFIG. 5specifically, two floor tiles1can be assembled together by fitting the second projection14A and the third projection14B of one floor tile1into the notches12of the other floor tile1. Another floor tile1then can be assembled with the above two assembled floor tiles1by fitting the second projection14A and the third projection14B thereof into the notches12of one of the above two assembled floor tiles1, and the first projection13into the notch12of the other of the above two assembled floor tiles1. Likewise, seven floor tiles1can be assembled as a pattern similar to a disk.

Referring toFIGS. 6 to 8, a modular floor tile in accordance with a second preferred embodiment of the invention is shown. The characteristics of the second preferred embodiment are substantially the same as that of the first preferred embodiment except the following:

A modular floor tile1A having a first color and a modular floor tile1B of the same shape but having a second color different from the first color are formed together as a unit. Each unit can be assembled with at least one unit to form a desired pattern.
