Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile carpet set composed of a plurality of tile carpets that are surface-filled lengthwise and breadthwise.

Conventionally, tile carpets having rectangular panel shapes such as squares and rectangles are known (see Patent Document 1, for example). For example, Patent Literatures 1 and 2 disclose a tile carpet set in which, when surface filling is performed, patterns are continuous across boundaries (joints) between tile carpets, forming a uniform pattern.

JP-A-2008-88676 Japanese Patent No. 5538374

By the way, when furniture such as desks and chairs are installed on a tile assembly in which a tile carpet is flat-filled, it is common to consider the size of the flow line when laying out the furniture. The size of the line of flow is the width required for a person to move along the line of flow. It is said to be 60 cm when one person faces the front, 30 cm when walking sideways, and 120 cm when two people pass each other. . In addition, the dimensions of furniture, for example, are often defined in multiples of 30 cm as a standard dimension derived from the Shakanho method in Japan. Therefore, if there is a mark on the floor that serves as a guideline for 30 cm, it is convenient when considering the layout of furniture and the like. In addition, if there is a mark on the floor that serves as a guideline for 1m, which is a dimensional unit, it will serve as a guideline when measuring a predetermined distance.

As mentioned above, if there are marks indicating dimensions on the floor surface (hereinafter referred to as "dimensional reference marks"), it is convenient in various situations. tile carpet is not provided.
In order to achieve this, if many types of tile carpets with different patterns are required, it is disadvantageous in terms of mass production, and it is difficult to prepare spare tile carpets in preparation for replacement when soiled. The advantage of the tile carpet, which is excellent in durability and handleability, is lost.

SUMMARY OF THE INVENTION An object of the present invention is to provide a highly convenient tile carpet set that can reveal a plurality of types of dimensional reference marks when surface-filled without significantly impairing mass productivity and handleability. be.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The tile carpet set 10 according to the present embodiment is mainly used by laying it on an indoor floor surface.

[First embodiment]
FIG. 1 is a diagram showing a tile aggregate 1 formed by a tile carpet set 10 according to the first embodiment. 2A to 2C are diagrams showing first to third tile carpets 11 to 13 that constitute the tile carpet set 10. FIG. 3A and 3B are diagrams showing the arrangement of the first to third tile carpets 11 to 13 in the tile carpet set 10. FIG. 1 and 3A to 3C, the directions of the reference characters "A", "B", and "C" indicate the directions of the first to third tile carpets 11 to 13. FIG.

As shown in FIG. 1, the tile aggregate 1 is formed by filling square tile carpets TC each side of which is X [cm]. In FIG. 1, joints (reference numerals omitted), which are boundaries between tile carpets TC, are indicated by dashed lines. Hereinafter, one side X [cm] of the tile carpet TC is referred to as "tile size X [cm]". In addition, in the tile assembly 1, the joints are almost invisible due to the uniformity of the pattern applied to the peripheral portion of the tile carpet TC.

A tile carpet set 10 (a portion surrounded by a thick line in FIG. 1) is the minimum unit repeated vertically and horizontally when forming the tile aggregate 1, and is composed of a plurality of tile carpets TC arranged according to a predetermined rule. be done. In the first embodiment, the tile carpet set 10 is composed of first to third tile carpets 11-13.

On the tile assembly 1, a first dimension reference mark M1 serving as a guideline for the first interval L1 [cm] and a second dimension reference mark M2 serving as a guideline for the second interval L2 [cm] are formed vertically and horizontally. ing. The first interval L1 and the second interval L2 are set equal to or smaller than the tile size X, for example.

The first dimension reference mark M1 and the second dimension reference mark M2 should be able to visually recognize the first interval L1 and the second interval L2. For example, the linear pattern itself formed on the tile aggregate 1 may serve as the first dimension reference mark M1 and the second dimension reference mark M2. Further, for example, imaginary straight lines that emerge from the pattern formed on the tile aggregate 1 may serve as the first dimension reference mark M1 and the second dimension reference mark M2 (see Modification 2).

In the first embodiment, the first dimension reference mark M1 is a grid pattern formed of solid linear patterns arranged at the first interval L1 in the vertical and horizontal directions. Similarly, the second dimension reference mark M2 is a lattice pattern formed by solid linear patterns arranged at the second interval L2 in the vertical and horizontal directions. The first dimension reference mark M1 and the second dimension reference mark M2 can be distinguished by the linear pattern (line width, color, etc.) of each lattice pattern. In FIG. 1, the first dimension reference mark M1 is indicated by a hatched line having a predetermined width, and the second dimension reference mark M2 is indicated by an outline line wider than the first dimension reference mark M1. A user can recognize the first interval L1 and the second interval L2 by visually checking the first dimension reference mark M1 and the second dimension reference mark M2.

In the tile aggregate 1, the first dimension reference mark M1 and the second dimension reference mark M2 appear in the same positional relationship with one period T being the least common multiple of the first interval L1 and the second interval L2. The first interval L1, the second interval L2, and the tile size X are the length in the vertical direction ( MX [cm]) and the horizontal length (NX [cm]) are set to be multiples of the period T.

In particular, when the tile size X and the second spacing L2 are the same, and n times the tile size X (=second spacing L2) is divisible by the first spacing L1, the tile carpet set 10 has an n×n arrangement. Become. For example, when the first distance L1 is 15 [cm], 30 [cm] or 37.5 [cm] and the second distance L2 is 50 [cm], the first dimension reference mark M1 and the second dimension reference mark M2 appears periodically at intervals of 150 [cm]. Therefore, if the tile size X at this time is 50 [cm], the tile carpet set 10 can be composed of nine tile carpets TC arranged in a 3×3 arrangement.

In the following, as an example of dimension settings, the first interval L1 is 30 [cm], the second interval L2 and the tile size X are 50 [cm], and the repetition period T of the tile carpet set 10 is 150 [cm]. A case will be explained. In this case, as shown in FIG. 1, the tile carpet set 10 is arranged in a 3×3 arrangement.

The tile carpet TC is decorated with a first pattern P1 forming a first dimension reference mark M1 and a second pattern P2 forming a second dimension reference mark M2 in the vertical and horizontal directions. The first pattern P1 and the second pattern P2 are, for example, decorated by printing on a resin base material such as polyurethane.

In the first embodiment, the pattern to be decorated on the tile carpet TC is devised so that the tile carpet set 10 is composed of fewer types of tile carpet TC (specifically, three types) than the number of constituent tile carpets. there is
Specifically, the tile carpet TC is composed of first to third tile carpets 11 to 13 having different patterns. A first pattern P1 and a second pattern P2 are formed on the first to third tile carpets 11 to 13 so that the first dimension reference mark M1 and the second dimension reference mark M2 overlap at a predetermined interval. Furthermore, the first to third tile carpets 11 to 13 have the following features with respect to the first pattern P1 and the second pattern P2.

The first tile carpet 11 is a tile carpet that serves as a reference when forming the tile carpet set 10, and is arranged in the center of the 3×3 array in FIGS. 3A and 3B. A second tile carpet 12 is arranged adjacent to the first tile carpet 11 in the vertical and horizontal directions, and a third tile carpet 13 is arranged adjacent to the first tile carpet 11 in the diagonal direction.

As shown in FIG. 2A, the first pattern P11 and the second pattern P21 of the first tile carpet 11 are formed with 90° rotational symmetry (4-fold rotational symmetry). It can also be said that the first pattern P11 and the second pattern P21 are symmetrical about the longitudinal and lateral centerlines S1, S2 and the diagonals S3, S4 of the square. Therefore, even if the direction of the first tile carpet 11 is rotated by 90 degrees, the appearance does not change.
Specifically, the first pattern P11 and the second pattern P21 of the first tile carpet 11 are each formed in a "+" shape so as to be vertically and horizontally divided into two (to divide the whole into four). . In FIG. 2A, the first pattern P11 is formed inside the wide second pattern P21.

In the first tile carpet 11, the lengths from the first pattern P11 and the second pattern P21 to the peripheral edge are respectively represented by L2/2. The length from the first pattern P11 and the second pattern P21 to the peripheral edge is the length from the center of the line width of the first pattern P11 and the second pattern P21 to the peripheral edge on the side closer to the line width direction. The same applies to the description of the second tile carpet 12 and the third tile carpet 13 as well. When L2=50 [cm], the lengths from the first pattern P11 and the second pattern P21 to the peripheral edges are both 25 [cm].

The second tile carpet 12 is a tile carpet arranged adjacent to the first tile carpet 11 in the vertical and horizontal directions. The contact side 12 a of the second tile carpet 12 contacts the first tile carpet 11 .

As shown in FIG. 2B, the first pattern P12 of the second tile carpet 12 is formed symmetrically with respect to the horizontal centerline S2.
Specifically, two first patterns P12 extending in the vertical direction are formed at a first interval L1. The length from the first pattern P12 on the contact side 12a side to the peripheral edge (contact side 12a) is set to L1-L2/2. At this time, the length from the other first pattern P12 to the peripheral edge (side opposite to the contact side 12a) is represented by 3L2/2-2L1. When L1=30 [cm] and L2=50 [cm], the lengths from the first pattern P12 to the peripheral edge are 5 [cm] and 15 [cm], respectively.
The first pattern P12 extending in the horizontal direction is formed along the center line S2 in the horizontal direction so as to be divided into two in the vertical direction, and overlaps the second pattern P22.

Also, the second pattern P22 of the second tile carpet 12 is formed with 90° rotational symmetry, like the second pattern P21 of the first tile carpet 11 . Specifically, the second pattern P22 is formed in a "+" shape so as to be vertically and horizontally divided into two (total four divisions). The length from the second pattern P22 to the peripheral edge is represented by L2/2. When L2=50 [cm], the length from the first pattern P12 to the peripheral edge is 25 [cm].

The third tile carpet is a tile carpet arranged diagonally adjacent to the first tile carpet 11 . A vertex 13 a of the third tile carpet 12 contacts the first tile carpet 11 .

As shown in FIG. 2C, the first pattern P13 of the third tile carpet 13 is formed symmetrically with respect to the diagonal line S3.
Specifically, two first patterns P13 extending in the vertical direction are formed at a first interval L1, and the lengths from the peripheral edge are set to L1-L2/2 and 3L2/2-2L1, respectively. ing. It is the same as the first pattern P12 extending in the vertical direction of the second tile carpet 12 . Similarly to the first pattern P13 extending in the vertical direction, the first pattern P13 extending in the horizontal direction also has lengths from the peripheral edge set to L1-L2/2 and 3L2/2-2L1, respectively. When L1=30 [cm] and L2=50 [cm], the lengths from the first pattern P13 to the peripheral edge are 5 [cm] and 15 [cm] in the vertical and horizontal directions.

Also, the second pattern P23 of the third tile carpet 13 is formed with 90° rotational symmetry, like the first pattern P11 of the first tile carpet 11 . Specifically, the first pattern P13 is formed in a "+" shape so as to be vertically and horizontally divided into two (total four divisions). The length from the first pattern P13 to the peripheral edge is represented by L2/2. When L2=50 [cm], the length from the first pattern P13 to the peripheral edge is 25 [cm].

The first to third tile carpets 11 to 13 are arranged as shown in FIGS. 3A and 3B, respectively. In FIG. 3B, reference characters "A", "B", and "C" correspond to the first to third tile carpets 11 to 13, respectively, and depending on the orientation of the reference characters, the states shown in FIGS. It shows the orientation of the first to third tile carpets 11 as a reference. The same applies to FIG. 1 as well.
While the first tile carpet 11 has no directionality, the second tile carpet 12 and the third tile carpet 13 have directionality, and when the orientation is rotated by 90°, the appearance changes. Change. That is, the second tile carpet 12 and the third tile carpet 13 are provided with rotationally asymmetric patterns.

As shown in FIGS. 3A and 3B, the second tile carpet 12 is arranged adjacent to the first tile carpet 11 in the longitudinal direction and the lateral direction in an appropriately rotated orientation. 3A and 3B, the second tile carpets 12 adjacent to each other are rotated by 90°, and the second tile carpets 12 facing each other in the vertical or horizontal direction with the first tile carpet 11 interposed therebetween are 180 degrees apart. ° Rotated orientation. The first pattern P11 and the second pattern P21 of the first tile carpet 11 are connected to the first pattern P12 and the second pattern P22 of the second tile carpet 12, respectively.

In addition, the third tile carpet 12 is arranged adjacent to the first tile carpet 11 in the diagonal direction in an appropriately rotated orientation. In FIGS. 3A and 3B, the third tile carpets 13 adjacent to each other are rotated by 90°, and the third tile carpets 13 facing diagonally across the first tile carpet 11 are rotated by 180°. It is oriented. Two sides of the third tile carpet 12 are in contact with the second tile carpet 12 . The first pattern P12 and the second pattern P22 of the second tile carpet 12 are connected to the first pattern P13 and the second pattern P23 of the third tile carpet 13 at the contact portion.

In the adjacent first tile carpet 11 and second tile carpet 12, the first patterns P11 and P12 sandwiching the contact portion are arranged with the interval L1. In the adjacent second tile carpet 12 and third tile carpet 13 as well, the first patterns P12 and P13 sandwiching the contact portion are arranged at the interval L1. Therefore, the tile carpet set 10 is formed with a grid pattern indicating the first dimension reference marks M1 with the spacing L1.
Also, in the first tile carpet 11 and the second tile carpet 12 adjacent to each other, the second patterns P21 and P22 sandwiching the contact portion are arranged at the interval L2. In the adjacent second tile carpet 12 and third tile carpet 13 as well, the second patterns P22 and P23 sandwiching the contact portion are arranged at the interval L2. Therefore, the tile carpet 10 is formed with a lattice pattern indicating the second dimension reference marks M2 with the interval L2.

Since the second tile carpet 12 and the third tile carpet 13 are arranged with their orientations changed with respect to the first tile carpet 11, it is preferable that they have identification marks that allow identification of their appearance and orientation. The identification mark may be attached to the surface of the second tile carpet 12 and the third tile carpet 13, or may be attached to the back surface. Since the user can easily grasp the appearance and orientation of the second tile carpet 12 and the third tile carpet 13 by referring to the identification marks, workability in laying the tile carpets is improved.

By repeatedly arranging the tile carpet set 10 in which the first to third tile carpets 11 are arranged as shown in FIG. 3A, the tile assembly 1 shown in FIG. 1 is formed.

As described above, the tile carpet set 10 according to the first embodiment is composed of three types of rectangular tile carpets TC (a plurality of types of tiles) each having a predetermined size, and the tile carpets TC are filled vertically and horizontally. to form a tile aggregate 1. The tile assembly 1 includes a second tile carpet 12 and a third tile carpet 13 having rotationally asymmetric patterns, and is formed by arranging the second tile carpet 12 and the third tile carpet 13 with different orientations. be. Further, when the tile aggregate 1 is formed, the first dimension reference mark M1 and the second dimension reference mark M2 are different in at least one of the vertical direction and the horizontal direction depending on the combination of patterns of the respective tile carpets TC. It appears repeatedly in the tile aggregate 1 at predetermined dimensional intervals.

According to the tile carpet set 10, the user can know the first interval L1 from the first dimension reference mark M1 formed on the tile assembly 1, and can know the second interval L2 from the second dimension reference mark M2. can be obtained. Therefore, when installing furniture such as desks and chairs, the two kinds of first dimension reference marks M1 and second dimension reference marks M2 with different intervals can be used as a guide, which improves convenience. For example, if the first interval L1 is 30 [cm] and the second interval L2 is 50 [cm], furniture can be installed in a layout that takes into account the size of the flow line, using the first dimension reference mark M1 as a guide. Alternatively, the second dimension reference mark M2 can be used as a guide to install furniture in a layout that takes social distance into consideration.
In addition, since the second tile carpet 12 and the third tile carpet 13 are used with their directions changed, the tile carpet set 10 can be composed of fewer types of tile carpets TC than the tile carpet set 10 is composed of. Therefore, the mass productivity of the tile carpet TC is not significantly impaired, and the inventory of spare tile carpet TC to be prepared for replacement when soiled, etc., can be reduced.
As described above, according to the tile carpet set 10, the two types of first and second dimension reference marks M1 and M2 can be made to appear when surface filling is performed without impairing mass productivity and handleability. Convenience is greatly improved.

The tile carpet set 10 also includes a first pattern P1 forming the first dimension reference mark M1, and a second pattern P2 having a different appearance from the first pattern P1 and forming the second dimension reference mark M2. have. On the second tile carpet 12 and the third tile carpet 13 having rotationally asymmetric patterns, the first pattern P1 is rotationally asymmetrically applied and the second pattern P2 is rotationally symmetrically applied. By arranging the tile carpet 12 and the third tile carpet 13 with their directions changed, the first patterns P1 are formed at predetermined intervals.
The second pattern P2 has 90° rotational symmetry and is connected regardless of the orientation of the tile carpet TC to form the second dimension reference mark M2. In designing the tile carpet TC that forms the dimension reference mark M2, only the first pattern P1 needs to be considered, which facilitates the design work.

In the tile carpet set 10, each tile carpet TC has a square outer shape, and when the tile aggregate 1 is formed, the first dimension reference mark M1 and the second dimension A reference mark M2 appears.
As a result, the user can install the furniture or the like using the two types of first dimension reference marks M1 and second dimension reference marks M2 with different intervals in each of the vertical direction and the horizontal direction as guides, thereby improving convenience. is further improved.

The tile assembly 1 also includes a first tile carpet 11 (first tile) and a second tile carpet 12 (second tile) arranged adjacent to the first tile carpet 11 in the vertical and horizontal directions. and a third tile carpet 13 (third tile) arranged diagonally adjacent to the first tile carpet 11 . The first pattern P11 of the first tile carpet 11 has 90° rotational symmetry, and the first pattern P12 of the second tile carpet 12 has a horizontal centerline S2 (one of the vertical and horizontal centerlines). ), and the first pattern P13 of the third tile carpet 13 is symmetrical about the diagonal line S3 of the square.
As a result, when the first to third tile carpets 11 to 13 are appropriately rotated and the surface is filled, the first patterns P11 to P13 are combined to form the first dimension reference mark M1.

Further, in the tile carpet set 10, the first dimension reference mark M1 and the second dimension reference mark M2 are linear patterns respectively formed by the first pattern P1 and the second pattern P2 when the tile aggregate 1 is formed. is shown by the two grid patterns with .
As a result, the user can directly recognize the two types of first dimension reference marks M1 and second dimension reference marks M2 with different intervals from the pattern formed on the tile aggregate 1. FIG.

Also, the first dimension reference mark M1 and the second dimension reference mark M2 appear outside the boundaries (joints) between the first to third tile carpets 11 to 13 adjacent to each other. That is, in the first to third tile carpets 11 to 13, the first patterns P11 to P13 and the second patterns P21 to P22 forming the first dimension reference mark M1 and the second dimension reference mark M2 are not peripheral portions, It is formed inside the first to third tile carpets 11-13.
As a result, compared to the case where the first patterns P11 to P13 and the second patterns P21 to P22 are formed on the peripheral edge portions of the first to third tile carpets 11 to 13, the first patterns P11 to P13 and the second patterns P21 are formed. ~P22 can be appropriately decorated with high precision. In addition, it is less likely to be affected by wear of the peripheral portion over time, and the accuracy of the first dimension reference mark M1 and the second dimension reference mark M2 can be ensured over a long period of time.
