FLOOR MAT

Abstract

The floor mat contains a main piece with a number of first interlocking elements configured along a circumference of the main piece at intervals. Each first interlocking element contains a protrusion and a gap. The main piece also has a number of corner elements, each configured at a corner of the circumference. A hollow frame member is for the embedment of the main piece and has a number second interlocking elements matching the first interlocking elements along an inner circumference of the frame member. Each corner of the frame member has two perpendicular cuts end-to-end connected together and a slant cut running through a joint of the perpendicular cuts. As such, the floor mat can be pieced together in all directions, regardless of which side is up. The frame members can have their corners adjusted and fit on the main pieces to conceal their exposed interlocking elements.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0021] As shown in FIGS. 1 to 3, a floor mat 3 according to an embodiment of the present invention is integrally formed and contains the following components.

[0022] There is a rectangular main piece 31.

[0023] Around a circumference of the main piece 31, there are a number of first interlocking elements 32 configured at intervals. Each first interlocking element 32 contains a protrusion 321 and a gap 322 connecting a neighboring first interlocking element 32's protrusion 321 or connecting a neighboring corner element 33 (see below). Each protrusion 321 is extended laterally from the circumference for a first distance.

[0024] There are a number of corner elements 33 at the main piece 31's corners, connecting gaps 322 or protrusions 321 of two first interlocking elements 32 from neighboring edges of the main piece 31, respectively. Each corner element 33 is extended from the circumference of the main piece 31 for a second distance. The second distance is smaller than the first distance and, specifically, the second distance is one half of the first distance.

[0025] The floor mat 3 further contains a rectangular and hollow frame member 4. There are a number of second interlocking elements 41 matching the first interlocking elements 32 along an inner circumference of the frame member 4. At each corner of the frame member 4, there are two perpendicular cuts 42 end-to-end connected together and a slant cut 43 running through a joint of the perpendicular cuts 42. The perpendicular cuts 42 form an included right angle and the slant cut 43 forms an included acute angle against each of the adjacent perpendicular cuts 42.

[0026] Please note the interlocking elements 11 along two opposing edges of the main piece 31 are staggered, meaning that one interlocking element 11's protrusion and gap 321 and 322 on one edge are aligned with another interlocking elements 11's gap 322 and protrusion 321 on an opposing edge, respectively.

[0027] To piece a number of floor mats of the present embodiment together, for reference's sake, one main piece is referred as 31a and another one is referred as 31b. As illustrated in FIG. 4, the main pieces 31a is first removed out of the corresponding frame members 4a. Then, assuming that a bottom edge of the main piece 31a is joined to a top edge of the main piece 31b. As shown in FIG. 5, the protrusions 321a are embedded into the gaps 322b and the corner elements 33a and 33b are matches against each other. Please note that, each main piece has a diagonal line from an upper right corner to a lower left corner, separating the main pieces into two symmetric halves L and R. Therefore, when a main pieces 31b joins to another main piece 31b, the main piece 31b can join to any edge of the main piece 31a as long as one's L half matches another's R half and vice versa. Please which side of the main piece is the top side is of no significance either. As such, the main pieces can be pieced together flexibly. Especially, where the main pieces are of different colors, various colorful patterns can be achieved. Please note that the corner elements 33a and 33b are extended from the circumferences of the main pieces 31a and 31b for a distance that is one half of the distance for which each protrusion (e.g. 321a) is extended from the from the circumferences of the main pieces 31a and 31b. The corner elements 33a and 33b exactly match each other without causing bulges.

[0028] Additionally, as shown in FIG. 6, each of the four corners of the frame member 4 can be removed along the perpendicular cuts 42 and/or the slant cut 43 so as to form corners of various shapes. Four edges 44 of the frame member 4 can also be removed individually. As shown in FIG. 7, after the main pieces 31a and 31b are pieced together, their corresponding frame members 4a and 4b can have their corners adjusted and fit on the main pieces 31a and 31b to conceal their exposed interlocking elements. As shown in FIG. 7, for frame member 4a and 4c, their joining corners are adjusted to have slant corners and therefore match each other exactly.

[0029] As described above, the floor mat of the present invention overcomes the prior art's disadvantages as follows.

[0030] With specially designed corner elements, floor mats can be pieced together regardless of which side is up. The floor mats can be pieced together in all directions. The perpendicular and slant cuts at the corners allow the corners to have various shapes to fit joining corners of neighboring floor mats.

[0031] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
