Description
BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention is related to an improvement in the structure of an anti-slip floor unit and in particular to one which can effectively prevent slipping as can easily be cleaned.

[0003] 2. Description of the Prior Art

[0004] Anti-slip floor units and similar devices are well known in the art to prevent people from slipping and to protect people from injury caused by felling. There are many variations on devices used to prevent slipping. As shown in FIGS. 1A and 1B, the conventional anti-slip floor unit is simply a board 1 formed thereon with a plurality of raised lines 11 for increasing the friction between the shoe and the board 1. FIGS. 2A and 2B show another conventional anti-slip floor unit. As illustrated, the anti-slip floor unit includes a board 2 formed thereon with a plurality of circular projections 21. Nevertheless, the above-mentioned anti-slip floor units cannot effectively preventing slipping and the dirt will easily accumulate in blind spots thereby making it very difficult to clean.

[0005] Therefore, it is an object of the present invention to provide an improvement in the structure of an anti-slip floor unit which can obviate and mitigate the above-mentioned drawbacks.

SUMMARY OF THE INVENTION

[0006] This invention is related to an improvement in the structure of an anti-slip floor unit.

[0007] It is the primary object of the present invention to provide an improvement in the structure of an anti-slip floor unit which can prevent the dirt from accumulating in blind spots thereby making it easier to clean and prolonging its service life.

[0008] It is another object of the present invention to provide an improvement in the structure of an anti-slip floor unit which includes a board formed thereon with a plurality of spherical swells, each of the spherical swells having a protuberance a center thereof, the spherical swells being equidistantly arranged on a top of the board.

[0009] It is still another object of the present invention to provide an improvement in the structure of an anti-slip floor unit wherein the distance between a top of the protuberance and the bottom of the board is 4.5 mm.

[0010] It is still another object of the present invention to provide an improvement in the structure of an anti-slip floor unit wherein the distance between two adjacent ones of the spherical swells is 47 mm.

[0011] It is a further object of the present invention to provide an improvement in the structure of an anti-slip floor unit wherein the spherical swell has a diameter of 20 mm.

[0012] The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.

[0013] Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014]FIG. 1A is a perspective view of a conventional anti-slip floor unit;

[0015]FIG. 1B is a sectional view of the conventional anti-slip floor unit;

[0016]FIG. 2A is a perspective view of a second conventional anti-slip floor unit;

[0017]FIG. 2B is a sectional view of the second conventional anti-slip floor unit;

[0018]FIG. 3 is a perspective view of the present invention;

[0019]FIG. 4 is a sectional view of the present invention; and

[0020]FIG. 5 is a top plan view of the present invention.

DETAILED DESCRIPTION OF THE PRESENT INVETION

[0021] For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, alterations and further modifications in the illustrated device, and further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

[0022] With reference to the drawings and in particular to FIGS. 3 and 4 thereof, the anti-slip floor unit 300 according to the present invention comprises a board 3 formed thereon with a plurality of spherical swells 31. Each of the swells 31 has a protuberance 32 at its center. The spherical swells 31 are equidistantly arranged on the top of the board 3. By means of spherical swells 31 and the protuberances 32, the dirt can be prevented from accumulating in blind spots thereby making it easier to clean the anti-slip floor unit 300 and prolonging its service life.

[0023] The anti-slip floor unit may 300 be made of metal such as stainless steel, and may be otherwise made of ceramic. The spherical swells 3 is formed by die casting, or integrally formed with the board 3.

[0024] Referring to FIGS. 4 and 5, the distance between the top of the protuberance 32 and the bottom of the board 3 is supposed to be X, and the distance between two adjacent protuberances 32 is supposed to be Y Then, through numerous experiments, the preferred value of X is 4.5 mm, while the preferred value of Y is 47 mm Further, the preferred diameter of the swell 31 is 20 mm.

[0025] It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

[0026] 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 spirit of the present invention.
