However, in the conventional foot wipe mat, as described in paragraph 0009 of Patent Document 1, each superabsorbent tile is fixed on the bottom plate constituting the support board. The specific fixing method is not specified in Patent Document 1, but referring to FIGS. 2 and 3 of Patent Document 1, it is considered that the superabsorbent tile is fixed to the bottom plate using an adhesive. It is normal. For this reason, when any one of the superabsorbent tiles is broken, it is difficult to replace only the cracked superabsorbent tile with a new one, and there is a problem that the entire foot wipe mat has to be replaced.

In the conventional foot wipe mat, the entire bottom surface of each superabsorbent tile is in close contact with the bottom plate of the support board, and the entire bottom surface of each superabsorbent tile is closed by this bottom plate. For this reason, there is also a problem that moisture is not released from the bottom surface of each superabsorbent tile, and the moisture-releasing efficiency of the superabsorbent tile is poor.

Furthermore, in the conventional foot wipe mat, the superabsorbent tiles are arranged side by side on the bottom plate of the support board with almost no gap. For this reason, there exists a problem that the water | moisture-content absorption and moisture discharge | release from the side surface of a highly water-absorbing tile are prevented.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a foot-wiping mat in which individual superabsorbent tiles can be easily replaced.

It is AA arrow sectional drawing of FIG.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, a foot-wiping mat 1 according to an embodiment of the present invention includes a superabsorbent tile 2, a support board 3 that can support a plurality of superabsorbent tiles 2 side by side, and a superabsorbent tile. A detachable fixing pin 4 for fixing the tile 2 to the support board 3 is provided. The foot-wiping mat 1 in FIG. 1 includes, as an example, a total of 35 superabsorbent tiles 2 in the vertical direction and 7 in the lateral direction, although the number of superabsorbent tiles 2 may be larger than this. It may be less. The foot-wiping mat 1 shown in FIG. 1 is used by being laid on the floor of a bathroom outlet or other water. When the user gets on the foot cleaning mat 1, moisture such as the sole of the user is absorbed by the super absorbent tile 2.

The super absorbent tile 2 includes diatomaceous earth. As described in Patent Document 1, diatomaceous earth is a phytoplankton (algae) carcass that floated in the sea, lakes, etc. 13 to 9 million years ago and deposited over a long period of time. It is petrified and contains silicate glass as the main component. It has innumerable pores of about 0.1 to 0.2 microns leading to the inside and outside, and has a fine and ultra-porous structure that is several thousand times that of charcoal. Performance, deodorizing properties, heat retaining properties, heat insulation properties, etc., and also has excellent properties of “respirability (humidity control / moisture absorption / release properties)” that releases moisture once absorbed.

For this reason, the highly water-absorbing tile 2 containing diatomaceous earth can sufficiently absorb moisture in a bathroom or the like, and can maintain a dry surface to make the user feel comfortable. Moreover, since it has the above-mentioned moisture absorption / release property, the moisture inside the superabsorbent tile 2 can be easily released by sun-drying the foot-wiping mat 1 in good weather or by applying the foot-wiping mat 1 to the wind. It can be used over a long period of time, and the hygiene state can be continued while suppressing the occurrence of mold and germs. In order to withstand sun-drying, the superabsorbent tile does not use materials that deteriorate due to sun drying.

As shown in FIG. 2, in this embodiment, the superabsorbent tile 2 is formed so that the length of one side in the vertical and horizontal directions is about 60 mm. For this reason, even if a user's weight is loaded on the foot-wiping mat 1, the superabsorbent tile 2 is hard to break, and the superabsorbent tile 2 can be easily manufactured and processed. As is clear from FIGS. 2B and 2C, the upper surface of the superabsorbent tile 2 swells in a part of a spherical surface, and can give a pleasant stimulus to the soles of the user, particularly the arch. it can. The thickness of the super absorbent tile 2 is, for example, about 7 to 10 mm at the thinnest portion and about 13 to 20 mm at the thickest portion in the center. For this reason, it has the necessary and sufficient strength, is difficult to break, and can secure a sufficient amount of water absorption. As the planar shape of the superabsorbent tile, various shapes such as a rectangle, a square, a triangle, and other polygons, as well as a circle and an ellipse can be adopted.

In FIG. 2, the four corners of the superabsorbent tile 2 having a rectangular shape in plan view are the thin portions 2 a having the same shape and the same dimensions, and the flat upper surface 2 b of each thin portion 2 a is formed of the superabsorbent tile 2. It is a position one step lower than the upper surface 2c. On each thin portion 2a, a head 4a of a fixing pin 4 described later in detail with reference to FIG. 4 is seated. The step between the upper surface 2c of the superabsorbent tile 2 and the flat upper surface 2b of each thin portion 2a forms a head fitting recess 2e that can receive the head 4a of the fixing pin 4, and this head The depth of the fitting recess 2e is substantially the same as the thickness of the head 4a of the fixing pin 4. For this reason, as shown in FIG. 6, in the fixed state of the superabsorbent tile 2 by the fixing pin 4, the upper surface 4 b of the head 4 a of the fixing pin 4 is continuous with the upper surface 2 c of the superabsorbent tile 2 without a step. Unnecessary protrusion from the upper surface of the water absorbent mat 1 is avoided.

The depth of the head fitting recess 2e may be deeper than the thickness of the head 4a of the fixing pin 4. Also in this case, the head 4 a of the fixing pin 4 is hidden in the head fitting recess 2 e of the superabsorbent tile 2 in the fixed state of the superabsorbent tile 2 by the fixing pin 4. For this reason, unnecessary protrusion from the upper surface of the super absorbent mat 1 can be avoided.

As shown in FIG. 2 (a), each thin portion 2a is formed in a right isosceles triangle shape having a corner 2d of the superabsorbent tile 2 as an apex in plan view. This corresponds to the fact that the head 4a of the fixing pin 4 is formed in a substantially square shape when viewed from above.

Next, the support board 3 will be described. As shown in FIG. 3, the support board 3 includes a rectangular frame-shaped outer peripheral frame 5 and a bottom plate 6 formed at a lower portion in the outer peripheral frame 5. The superabsorbent tile 2 is disposed on the bottom plate 6. The entire support plate 3 is integrally formed of plastic as a material. However, it is also possible to form the support plate 3 by forming the outer peripheral frame 5 and the bottom plate 6 separately and bonding them with an adhesive, or integrating them using a fixing tool such as a screw.

On the upper part of the inner surface of the outer peripheral frame 5, a bowl-shaped adjacent tile holding piece 7 is formed which simultaneously presses the thin portions 2a, 2a of the two superabsorbent tiles 2, 2 adjacent to each other and holds them so that they cannot fall out. Is done. These adjacent tile holding pieces 7 fix the superabsorbent tile 2 immediately inside the outer peripheral frame 5 of the support board 3 to the support board 3 in cooperation with the head 4 a of the fixing pin 4. The thickness of the adjacent tile holding piece 7 coincides with the size of the step between the upper surface 2c of the superabsorbent tile 2 and the flat upper surface 2b of each thin portion 2a. For this reason, in the holding state of the superabsorbent tile 2 by the adjacent tile holding piece 7, the upper surface of the adjacent tile holding piece 7 is continuous with the upper surface 2 c of the superabsorbent tile 2 without a step.

Further, corner tile holding pieces 8 are formed in a bowl shape immediately inside the four corners of the outer peripheral frame 5. The corner tile holding piece 8 presses the thin portion 2a of the superabsorbent tile (corner tile) 2 disposed just inside the four corners of the outer peripheral frame 5, and cooperates with the head 4a of the fixing pin 4, Hold the corner tile 2 so that it cannot fall out. The thickness of the corner tile holding piece 8 coincides with the size of the step between the upper surface 2c of the super absorbent tile 2 and the flat upper surface 2b of each thin portion 2a. For this reason, in the holding state of the superabsorbent tile 2 by the corner tile holding piece 8, the upper surface of the corner tile holding piece 8 is continuous with the upper surface 2 c of the superabsorbent tile 2 without any step.

The bottom plate 6 supports the superabsorbent tiles 2 in an orderly and vertical arrangement. A large number of air holes 9 are formed in the bottom plate 6. For this reason, the water | moisture content absorbed by the highly water-absorbing tile 2 can also be discharge | released from the bottom face 2e (refer FIG.2 (b), (c)) of the highly water-absorbing tile 2 through the vent hole 9. FIG. Therefore, the moisture-releasing property of the super absorbent tile 2 is improved. The vent holes 9 may have any mode, but a mode in which the vent holes 9 are uniformly distributed over the entire surface of the bottom plate 6 and the total area of the vent holes 9 is as wide as possible is preferable. In the example of FIG. 3, the bottom plate 6 is formed in a lattice shape, and the gap between the lattices is a vent hole 9. In this way, since the total area of the air holes 9 becomes large, the moisture releasing property from the bottom surface 2f of the superabsorbent tile 2 is further improved.

On the bottom plate 6, a ridge 10 is formed as a positioning member for arranging the superabsorbent tile 2 at a predetermined tile accommodation position. These ridges 10 abut on the side surfaces of the superabsorbent tile 2, whereby each superabsorbent tile 2 is held at a predetermined tile accommodation position on the bottom plate 6. For this reason, the arrangement | work operation | work of the some high water absorption tile 2 on the baseplate 6 can be performed correctly and rapidly. The superabsorbent tile 2 adjacent to the inner surface of the outer peripheral frame 5 constituting the support board 3 is held at the tile accommodation position by the protrusion 10 and the inner surface 5a of the outer peripheral frame 5. As shown in FIG. 3, of the protrusions 10, the protrusions 10 a and 10 a that form the corner tile accommodating portions 11 immediately inside the four corners of the outer peripheral frame 5 are adjacent tile holding pieces adjacent to the corner tile holding pieces 8. In order to facilitate insertion of the superabsorbent tile 2 under the pieces 7, 7, the outer peripheral frame 5 is inclined downward toward the outside.

The protrusions 10 have a function of positioning the high water-absorbing tile 2, and also have a function of a spacer for forming a gap S between the high water-absorbing tiles 2 and 2 adjacent to each other. The width of the gap S is, for example, about 2 mm. If it does in this way, the water | moisture content absorbed by the highly water absorbing tile 2 can be discharge | released also from the side surface of the highly water absorbing tile 2 through the said clearance gap S. FIG. Therefore, the moisture-releasing property of the super absorbent tile 2 is further improved. In addition, water absorption from the side surface of the superabsorbent tile 2 is also possible through the gap S, so that the hygroscopicity of the superabsorbent tile 2 is also improved.

Instead of the protrusions 10, a plurality of protrusions may be provided in the extending direction of the protrusions 10, and these protrusions may be used as positioning members and spacers.

A pin insertion hole 12 for receiving the fixing pin 4 is formed through the bottom plate 6. The shape of the pin insertion hole 12 is a shape corresponding to the shape of the fixed pin 4. In the example of FIG. 3, the pin insertion hole 12 has a cross shape when viewed from above. The pin insertion hole 12 is formed in the intersection part of the protrusion 10 extended vertically and horizontally.

As shown in FIG. 4, the fixing pin 4 includes a substantially square flat plate-like head portion 4a as viewed from above, and elastic leg portions 4c extending downward from the lower surface of the head portion 4a. The elastic legs 4 c allow the fixing pins 4 to be press-fitted into the pin insertion holes 12 of the bottom plate 6 of the support board 3. The elastic leg portion 4c is formed with a retaining portion 4d that can be released using the elasticity of the elastic leg portion 4c. The planar shape of the head 4a of the fixing pin 4 may be circular. The fixing pin 4 is entirely made of plastic.

In the fixing pin 4 of FIG. 4, four elastic legs 4c are formed with respect to the head 4a, and a retaining part 4d is formed outside the lower part of each elastic leg 4c. When the fixing pin 4 is press-fitted into the pin insertion hole 12 of the support plate 3, as shown in FIG. 6, the retaining portion 4 d is locked to the back side of the bottom plate 6 of the support plate 3, thereby preventing the fixing pin 4 from falling off. Is done. If FIG. 4B is a front view of the fixing pin 4, both the left and right side views and the rear view of the fixing pin 4 appear in the same manner as the front view. An inclined guide surface 4e that allows press-fitting into the pin insertion hole 12 is formed at a position below each retaining portion 4d. In the present embodiment, the pin insertion holes 12 are formed in a cross shape so as to correspond to the four elastic legs 4 c of the fixing pin 4.

As shown in FIG. 5, in the present embodiment, a collective corner portion (aggregate of thin portions 2 a) 13 formed at the central portion of the aggregate of four superabsorbent tiles 2 arranged two by two vertically and horizontally. Is fixed by the fixing pin 4. That is, one fixing pin 4 exerts a fixing action on the aggregate of superabsorbent tiles 2. For this reason, it is possible to fix all the superabsorbent tiles 2 on the support board 3 with a smaller number of fixing pins 4 than the total number of superabsorbent tiles 2.

Next, a method for fixing the super absorbent tile 2 with the fixing pins 4 will be described. First, the superabsorbent tiles 2 are arranged in all the tile accommodation positions of the support board 3. At this time, from the viewpoint of ease of insertion, the superabsorbent tile 2 is first inserted into the four corner tile accommodating portions 11, and then the superabsorbent tile is placed at the tile accommodating position immediately inside the outer peripheral frame 5 of the support board 3. 2 is inserted, and then the superabsorbent tile 2 is placed in the remaining tile receiving positions. In the superabsorbent tile 2 disposed just inside the outer peripheral frame 5 of the support board 3, the thin portion 2 a on the outer peripheral frame 5 side is held by the corner tile holding piece 8 and the adjacent tile holding piece 7. In addition, as shown in FIG. 5, a collective corner 13 is formed by the aggregate of the thin portions 2 a at the center of the aggregate of the four superabsorbent tiles 2 arranged vertically and horizontally on the support board 3. Is done. A pin insertion hole 12 formed in the bottom plate 6 of the support board 3 is located at the center of the collective corner 13. Therefore, the elastic leg 4c of the fixing pin 4 is press-fitted into the pin insertion hole 12.

As shown in FIG. 4, when the four elastic leg portions 4c are press-fitted into the pin insertion holes 12, the inclined guide portions 4e of the elastic leg portions 12 are pressed against the inner surface of the pin insertion holes 12, and each elastic leg portion 4c. Is elastically deformed inward of the pin insertion hole 12. Then, as shown in FIG. 6, when the retaining portions 4 d of the elastic legs 4 c pass through the pin insertion holes 12, the retaining portions 4 d become the back surface of the bottom plate 6 of the support plate 3 due to the elasticity of the elastic legs 4 c. To engage. Thereby, the fixing pin 4 is fixed to the support board 3, and the collective corner 13 of the four superabsorbent tiles 2 is fixed to the support board 3 by the head 4 a of the fixing pin 4. On the back side of the bottom plate 6 of the support board 3, a recess 14 is formed that accommodates a portion of the elastic leg portion 4 c of the fixing pin 4 below the retaining portion 4 d. For this reason, the lower end portion of the fixing pin 4 does not protrude from the lower surface of the bottom plate 6 of the support board 3. In addition, in FIG. 6, the code | symbol 15 has shown the floor surface on which the foot-wiping mat 1 is mounted.

The fixing pin 4 can be removed from the support board 3 as needed. In FIG. 6, the fixing pin 4 is removed by inserting a screwdriver tip (not shown) or the like into the recess 14 on the back surface of the bottom plate 6 of the support plate 3 and utilizing the elasticity of the elastic leg 4c. This can be easily performed by releasing the engagement of the retaining portion 4d. For this reason, when the superabsorbent tile 2 is damaged or the like, only the damaged superabsorbent tile 2 can be easily replaced by removing the fixing pin 4.

In the embodiment of FIGS. 1 to 6, the method of fixing the collective corner 13 of the four superabsorbent tiles 2 with the fixing pins 4 has been described. As another example, a tile-side pin insertion hole is formed in the center of the superabsorbent tile, for example, and this tile-side pin insertion hole is used to fix the superabsorbent tile to the support board with a fixing pin. It is also possible to adopt a method to do. In this case, the fixing pin is inserted into the tile-side pin insertion hole of the highly water-absorbing tile and then press-fitted into a pin insertion hole (support-side pin insertion hole) formed in the support board, thereby achieving high water absorption. Removably fix the tile to the support board. The specific configuration of the fixing pin in this case can be substantially the same as that of FIG. 4, and for the highly water-absorbing tile, in FIG. 2, instead of the head fitting recesses 2 e at the four corners, What is necessary is just to employ | adopt the super absorbent tile which formed the head fitting recessed part which receives the head of a fixing pin in the center part. The fixing pin in this case may be a separate body from the superabsorbent tile 2, or may be formed integrally with the superabsorbent tile 2.

However, the embodiment shown in FIGS. 1 to 6 is superior to the other example in the following points. That is, according to the embodiment of FIGS. 1 to 6, since one fixing pin 4 has a fixing action on the aggregate of the superabsorbent tiles 2, the number of fixings is smaller than that of the superabsorbent tiles 2. All the super absorbent tiles 2 can be fixed with the pins 4. Moreover, since it is not necessary to form the tile side pin insertion hole in the highly absorbent tile 2, there is an advantage that the highly absorbent tile 2 is difficult to break.
