Dimensions. Here, the dimension of the gap S1 is a dimension between the base members 1 in the adjacent floor covering A1, and is set to 2 mm, for example. In this case, the length dimension L1 of one side of the base member 1 is 148 mm. And the width dimension W1 of the boundary part 11 between the unit area | regions 10 in the base member 1 shall be 2 mm which is the same as the dimension of the said clearance gap S1. The length dimension of one side of each unit region 10 is 73 mm.

  FIG. 7 shows another example of a floor covering according to the present invention. The floor covering A2 shown in FIG. 7 has basically the same configuration as the floor covering A1 described above, but is different in size from the floor covering A1. In addition, about the floor covering A2 shown by the figure, the same code | symbol as the floor covering A1 is attached | subjected to the same or similar element as said floor covering A1, and description is abbreviate | omitted suitably.

  The floor covering A2 is configured as a large size, and the size is, for example, 450 mm square. Accordingly, the floor covering A2 is three times as large as the floor covering A1, and accordingly, the number of unit regions 10 constituting the base member 1 is different from that of the floor covering A1. ing. That is, in the floor covering A2, the unit regions 10 are integrated in six rows and six columns via the boundary portion 11, and have a total of 36 unit regions 10. In addition, although detailed illustration description is abbreviate | omitted, each unit area | region 10 in the floor covering A2 is set as the structure similar to the unit area 10 of the said floor covering A1, The above-mentioned lattice wall 12 and the additional wall 13 are comprised.

  As shown in FIG. 7, in the floor covering A <b> 2, the cylindrical portion 2 is arranged at six locations corresponding to the unit region 10 in each side surface portion 1 a, and the locking portion 3 is also each side surface portion. 1b is arranged at six locations corresponding to the unit area 10. By inserting the engaging portion 3 in the other floor covering A2 into the tubular portion 2 in one floor covering A2, the tubular portion 2 and the engaging portion 3 are engaged with each other, so that Floor coverings A2 can be connected.

  FIG. 8 shows a state where a plurality of floor coverings A2 are connected. As shown in the figure, a gap S2 having a predetermined width is formed at the joint between adjacent floor coverings A2.

  The size (450 mm) of the floor covering A2 is a pitch dimension of the floor covering A2 in a connected state, and is a dimension obtained by adding the length dimension L3 of one side of the base member 1 and the dimension of the gap S2. It is. Here, the dimension of the gap S2 is the dimension between the base members 1 in the adjacent floor covering A2, and is set to 2 mm which is the same as the gap S1 of the adjacent floor covering A1. The length dimension L3 of one side of the base member 1 in the floor covering A2 is 448 mm. And the width dimension W2 of the boundary part 11 between the unit area | regions 10 in the base member 1 shall be 2 mm which is the same as the dimension of the said clearance gap S2. A length dimension L4 of one side of each unit region 10 is 73 mm.

  As understood from the configurations of the floor covering A1 and the floor covering A2, the small size floor covering A1 and the large size floor covering A2 can be connected to each other.

  The floor coverings A1 and A2 having the above configuration are spread and used on the floor surface in a state where a plurality of floor coverings A1 and A2 are connected vertically and horizontally so as to have a desired size. When using the floor coverings A1 and A2, first, prepare the desired number of floor coverings A1 and A2, and connect the floor coverings A1 and A2 in the vertical and horizontal directions as described above. And spread in the windbreak room. Here, the entire peripheral portions of the floor coverings A1 and A2 are cut as necessary. Next, a liquid adhesive is poured into the gaps S1 and S2 of the joints between the floor coverings A1 and A2, and the floor coverings A1. The whole of A2 is fixed integrally (see FIG. 9).

  FIG. 10 is a plan view showing an example of a usage state in which a plurality of floor coverings A1 and A2 are connected vertically and horizontally. In the figure, a case where a plurality of floor coverings A1 and A2 are laid out so as to surround the warning / guidance panel P is schematically shown.

  In FIG. 10, it is set as the arrangement | positioning corresponding to the conventional floor coverings X1 and X2 mentioned above with reference to FIG. 12, and in the position where the small floor covering X1 was placed in FIG. The floor covering A1 is placed, and the large floor covering A2 is placed at the position where the large floor covering X2 is placed in FIG. In FIG. 10, in order to distinguish the boundary of the floor covering A1 (A2) from the boundary of the unit area 10, the seam of the floor covering A1 (A2) is represented by a bold line, and the boundary portion 11 of the unit area 10 is displayed. Is represented by a thin line.

  According to the floor covering A1 (A2), the plurality of unit regions 10 arranged in a plurality of rows and a plurality of columns in the base member 1 are separated from each other by the boundary portion 11 having a predetermined width. Thereby, on the upper surface of the base member, a mode in which the plurality of unit regions 10 are arranged vertically and horizontally appears. When using a plurality of floor coverings A1 (A2) connected vertically and horizontally, the seam between adjacent floor coverings A1 (A2) is an adjacent unit region 10 in each floor covering A1 (A2). It is difficult to distinguish the boundary portion 11 between the two. Therefore, the plurality of connected floor coverings A1 (A2) appear to have the same unit region 10 continuously arranged regardless of the presence or absence of the joint. As a result, the appearance of the connected floor covering A1 (A2) is good.

  The floor coverings A1 and A2 each have a plurality of unit regions 10 having the same configuration, and these unit regions 10 are arranged vertically and horizontally via a boundary portion 11 having the same width. Therefore, as shown in FIG. 10, even when floor rugs A1 and A2 having different sizes are mixed and spread, a plurality of connected floor rugs A1 and A2, regardless of the presence or absence of a seam, It appears that the same unit areas 10 are continuously arranged. As a result, the appearance of the floor coverings A1 and A2 having different sizes can be well maintained.

  In the floor covering A1 (A2), the upper part of the lattice wall 12 of each unit region 10 has an uneven shape including a convex portion 12a and a concave portion 12b. Thereby, the stain | pollution | contamination of a shoe sole is easy to be removed and dust removal property can be improved.

  The convex portions 12 a in the lattice wall 12 are provided between the intersections 123 between the vertical walls 121 and the horizontal walls 122 and between two adjacent intersections 123. On the other hand, the recess 12 b is provided in a portion adjacent to each vertical wall 121 in the upper end edge of each horizontal wall 122 and a portion adjacent to each horizontal wall 122 in the upper end edge of each vertical wall 121. For this reason, when a part of the base member 1 is cut, for example, as shown in the cut lines C1 and C2 indicated by phantom lines in FIG. It is possible to cut along 12b. Therefore, according to arrangement | positioning of the above-mentioned convex part 12a and the recessed part 12b, workability | operativity at the time of cutting | disconnection of floor covering A1 (A2) can be improved.

  A cross-shaped additional wall 13 is provided in the grid of the lattice wall 12, and the additional wall 13 includes an intermediate intersection 131, an inclined portion 132 adjacent to the central intersection 131, and an inclined portion. And a connection portion 133 adjacent to the lattice wall 12. According to such a configuration having the inclined portion 132 and the connecting portion 133, when the base member 1 is cut, the inclined portion 132 guides the connecting portion 133 to be cut. Therefore, this configuration is suitable for cutting along the vertical wall 121 or the horizontal wall 122, and is suitable for improving workability at the time of cutting the floor covering A1 (A2).

  Further, the upper end edge of the connection portion 133 is positioned lower than the recess 12 b of the lattice wall 12. For this reason, the vertical sectional area of the connecting portion 133 is smaller than the vertical sectional area of the lattice wall 12. Thereby, since the cutting force in the additional wall 13 at the time of cutting | disconnection of floor covering A1 (A2) may be small, cutting work can be performed smoothly.

  Since the central intersection 131 of the additional wall 13 is provided with a protrusion 13a that protrudes upward, the protrusion 13a can improve dust removal. Further, the additional wall 13 has a cross-shaped inclined portion 132 connected to the central intersection portion 131, and the upper end edge of the inclined portion 132 is displaced downward as the distance from the central intersection portion 131 increases. According to the configuration having such an inclined portion 132, it has a function as a reinforcement of the protrusion 13a, and the removed object is guided by the lattice wall 12 and the removed object (for example, pebbles) from the shoe sole downward. It is possible to suppress clogging between the additional walls 13. Further, as described above, the vertical sectional area of the connecting portion 133 of the additional wall 13 is smaller than the vertical sectional area of the lattice wall 12. According to such a configuration, when a vertical load is applied to the additional wall 13, the amount of elastic deformation in the vertical direction is larger than when a vertical load is applied to the lattice wall 12. Therefore, according to the structure which comprises the additional wall 13, the effect which improves the cushioning property of floor covering A1 (A2) can be anticipated.

  The two side surfaces provided with the cylindrical portion 2 are provided with a flat plate portion 16 whose base end is connected to the lower portion of the base member 1. The flat plate portion 16 extends to the outside of the base member 1 in a plan view, and is provided with a belt-like protrusion 16a protruding upward at the tip. As a result, when the floor covering A1 is connected, as shown in FIG. 9, the flat protrusion 16 abuts the lower portion of the side face 1b of the adjacent floor covering A1, and the belt-like protrusion 16a is in contact with the side face 1b. By engaging with the lower part of the floor, the gap between the two adjacent floor coverings A1 (A2) is defined within a certain range, and positioning is achieved. Further, according to the configuration in which the strip-shaped protrusion 16a is provided at the tip of the flat plate portion 16, it is possible to prevent the adhesive B poured into the joint of the floor covering A1 (A2) from flowing down to the floor surface. It is preferable for properly maintaining the connected state of the floor covering A1 (A2).

  A concave step portion 15 is formed on the lower surface of the base member 1. Thereby, the weight reduction of floor covering A1 (A2) can be achieved. Further, when there is a need to eliminate the steps of the connected peripheral edge portions, for example, an edge member (not shown) having an inclined surface (not shown) is attached over the peripheral edge or lower surface of the floor covering A1 (A2). At this time, it is necessary to cut off the cylindrical portion 2 or the locking portion 3 and a part of the protrusion 14 formed on the lower surface of the base member 1, but the step portion 15 has a certain dimension from each of the side surface portions 1a and 1b. It is formed in a range where the inner positions are the boundary lines 15a and 15b. For this reason, the boundary lines 15a and 15b can be used as marks for defining the cutting range of the protrusion 14 and the like. According to this structure, the workability | operativity at the time of attaching the said edging member is improved.

  While specific embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention. The specific shape, material, dimensions, etc. of each part of the floor covering according to the present invention are not limited to the above embodiment.

  In the above-described embodiment, as an example, the additional wall 13 includes the inclined portion 132 that is displaced downward as the upper end edge moves away from the central intersection 131 and the connection portion 133 that has a constant upper end edge. Although described, it is not limited to this. For example, as shown in FIG. 11A, the connection portion 133 has a flat surface having a certain height because the upper end edge is inclined so as to continuously connect with the upper end edge of the inclined portion 132. Also good. In addition, as shown in FIG. 11B, a configuration in which a step in the height direction is provided between the connecting portion 133 and the inclined portion 132 may be employed.
