Description

  The present invention relates to a decorative tile having a planar outer shape that can be spread on a wall surface and used. More specifically, it is equipped with a decorative layer made of a material that warps or bulges when it is stretched on the wall without gaps, especially when it is stretched due to the influence of humidity and / or temperature, such as woody materials and bamboo-like materials. Related to decorative tiles. Here, the wall surface is a concept including a floor surface.

  In this specification, the floor surface is taken as an example of the wall surface on which the decorative tiles are stretched. However, application of the decorative tile of the present invention to other wall surfaces, standing wall surfaces, ceiling wall surfaces, and the like can be expected. In addition, the case of using rattan (stems of palm tree vines) as an example will be described as an example, but other woody materials, bamboo-based materials, and as described above, they are stretched on the wall surface without any gaps. In this case, any natural material or synthetic material (hygroscopic plastic) can be used as long as the material warps or swells.

  In recent years, as natural materials have attracted attention as daily necessities and health items, wooden and bamboo materials have been reviewed as floor materials. Among them, rattan is not only used as a flooring material for ordinary houses because of its excellent luster, touch and durability, but is also widely used as a flooring material for dressing rooms at public baths in golf courses and inns.

  As such a flooring rattan (decoration) tile, for example, there is a rectangular plate shape in which a base layer, a cushion layer, and a rattan decoration layer (rigid decoration layer) are laminated in order from the bottom and integrated with an adhesive. Here, the base layer is formed of a rubber sheet or the like in order to ensure laying property or familiarity with the wall surface. The cushion layer is formed of felt or the like for softening the touch to the sole. As the rattan decorative layer, a lot of wicker strips arranged in a vertical direction and bound in a slat-like shape with a string or the like (hereinafter referred to as “rattan table”) are often used.

  Conventionally, for example, a decorative tile made of rattan has been used by laying down a peripheral edge of the post-processed edge with a cloth, a warp yarn, or the like while directly attaching it to the floor (Patent Document 1).

  However, since the rattan decorative layer of the decorative tile laid in this way is rich in elasticity when it is absorbed or dried due to high and low humidity and temperature, the rattan decorative layer and the cushion layer are bonded to each other. Warpage and swelling occur in the decorative layer. This phenomenon causes a problem that a step is generated at the boundary between the tiles and the sole is easily caught by the end of the rattan decorative layer.

  In order to solve this problem, the applicant of the present application has previously proposed "a rattan rug characterized by the fact that the rattan leather strips are arranged obliquely with respect to the longitudinal and lateral directions of the rattan rug and are bound with a string" (Patent Document). 2). However, even though the catch can be prevented, it does not prevent warping or swelling of the rattan decorative layer.

Furthermore, even if it is necessary to dry the nonwoven fabric used for the cushion layer in order to keep the floor surface clean, the rattan decorative layer and / or cushion layer cannot be removed from the base layer, and hygiene management is not possible. There was also a problem with ease.
Japanese Utility Model Publication No. 6-37432. JP 2002-45289 A

  In view of the above problems, an object of the present invention is to provide a decorative tile that does not warp or swell even when the decorative layer absorbs moisture or dries due to high or low humidity and temperature, and is easy to manage hygiene. .

In order to solve the above problem, the present invention is a decorative tile having a planar outer shape that can be used by spreading on a wall surface,
A decoration forming member and a tile frame that detachably holds the decoration forming member;
The decoration forming member includes a rigid decoration layer of a rigid material that expands and contracts depending on humidity and / or temperature,
The tile frame includes a molding part that covers both ends in the extending direction of the decoration forming member by absorbing the extension amount, and the molding part is configured to hold the decoration forming member detachably. It is a decorative tile.

  Since the decoration forming member and the tile frame are detachable, it is possible to remove only the decoration forming member as necessary even after the decoration tile is applied to the floor, and the back surface of the decoration forming member is dried and further cleaned.・ Sterilization is possible. The back surface of the decoration forming member is poorly ventilated, and bacteria (pathogenic bacteria), mold, mites, etc. are likely to be generated.

  Further, in the structure in which the decoration forming member is held by the molding, the decoration forming member has a gap that absorbs the extension amount at both ends in the extending direction of the decoration forming member, so that the decoration layer interferes with the decoration forming member of the adjacent tile. Can prevent swelling.

  The decorative tile according to the present invention usually has a configuration in which the decorative forming member includes a rigid decorative layer made of a rigid material that expands and contracts depending on humidity and / or temperature, and a cushion layer that backs the rigid decorative layer, and the cushion layer is appropriately selected. Is configured so as to be removable from the rigid decorative layer.

  In this case, the cushion layer has an effect of preventing sound accumulation while giving a soft feeling during walking. When the rigid decorative layer and the cushion layer are removable, it becomes easier to dry, clean, and disinfect the cushion layer on the back surface side of the decorative tile. The cushion layer is more desirable from the viewpoint of hygiene because it easily absorbs moisture and bacteria (pathogenic fungi), molds, mites, etc. easily propagate.

  In addition, in the configuration in which the decoration forming member according to the present invention is detachably held, it is desirable that the molding part be formed to be elastically compulsorily expanded so that the decoration forming member can be easily attached and detached. Here, if the molding part is formed of a plate member made of a synthetic resin that can be elastically deformed, the attachment and detachment is further facilitated.

  Usually, it is desirable that the tile frame is rectangular (rectangular) and the molding part is formed on four sides. Usually, it is easy to spread on the wall surface (floor surface) which is a square (rectangle), and in that case, it is not necessary to consider the directionality.

  Further, the rigid decorative layer of the decoration forming member is usually formed by parallel or knitting wood strips or bamboo strips (hereinafter referred to as “wood strips”).

  The decoration forming member preferably includes a rigid decoration layer formed by connecting rattan strips in parallel and a backing layer such as felt that can be stretched and tracked. Rattan does not give a dull feeling because it has better moisture absorption and breathability than other natural materials and is resistant to moisture and moisture. This is because the rattan is a stem of a palm tree vine that is cultivated in hot and humid Southeast Asia. Felt is inexpensive and has air permeability, moisture absorption and moisture release, and can be expected to contribute to air purification in cooperation with the rattan strip. If a sterilizing fiber such as copper is mixed in the felt, a sterilizing effect can be expected.

  An elastomer material is desirable as the base member of the tile frame. It can absorb minute irregularities on the wall surface and improve the workability of laying.

Hereinafter, preferred embodiments of the present invention will be described in detail. Here, a rattan table is taken as an example of the rigid decorative layer, and a case where a square decorative tile is applied to the floor surface is described as an example, but the present invention is not limited to this. Various embodiments are within the scope described in each claim in the claims section.

  Further, the decorative tile is not limited to a rectangle including a square, and may be any shape such as a triangle, a rhombus, a trapezoid, and a hexagon as long as it can be spread on a wall surface.

  One embodiment of a decorative tile is shown in FIGS. FIG. 2 shows a section 2-2 of the decorative tile of FIG.

  Basically, it includes a decoration forming member 10 and a tile frame 20 that detachably holds the decoration forming member 10.

  The decorative layer forming member 10 includes a rigid decorative layer (rattan surface) 12 and a cushion layer 14 that backs the rigid decorative layer. The decoration forming member may be only the rigid decoration layer 12. The rigid decorative layer 12 is not particularly limited as long as it is a rigid material that expands and contracts due to humidity and / or temperature. However, the rigid decorative layer 12 is formed by parallel or knitting wood strips or bamboo strips (hereinafter referred to as “wood strips”). It is desirable that A wood strip or the like is a natural material that breathes, contributes to air purification (improvement of indoor environment: making amenity), and allows ventilation and vapor passage to the lower layer. A synthetic resin strip or the like may be connected in parallel or knitted. At this time, the thickness of the rattan surface (rigid decorative layer) 12 is usually 1 to 2 mm.

  Moreover, as a material of the cushion layer 14, felt (nonwoven fabric), knitted fabric (pile fabric), sponge sheet, or the like can be used. As the felt, non-woven fabric made of synthetic fibers such as polyester fiber, nylon fiber, polypropylene fiber and acrylic fiber can be used, and carpets such as tufted carpet, woven carpet and knitted carpet can also be used. In this example, a nonwoven fabric made of synthetic fibers was used. The cushion layer 14 may be unnecessary depending on the purpose of installation, but when it is provided, its thickness can be designed freely. For example, it is set to 0.5 to 4 mm.

  And the total thickness of the rattan surface 12 and the cushion layer 14 shall be 2-7 mm, for example. The Wisteria table 12 and the cushion layer 14 are usually integrated with a urethane-based or rubber-based adhesive, but may be partially bonded with a double-sided adhesive tape so as to be easily separated after use over time. The cushion layer 14 may be removable from the rattan surface 12 with a hook-and-loop fastener or the like.

  Further, the tile frame 20 has a rectangular shape (a square in the illustrated example), and includes a base layer 22 and a molding part 24 that is attached to four sides of the base layer 22.

  As the material of the base layer 22 of the tile frame 20, a rigid board such as a plywood board, a hard board, and a particle board can be used, but an elastomer material such as natural / synthetic rubber or thermoplastic elastomer (TPE) is usually used. . As natural / synthetic rubber, ethylene propylene rubber (EPM), chloroprene rubber (CR), etc. having weather resistance are desirable. Examples of TPE include ester, amide, urethane, styrene, and olefin. Further, although not shown in the figure, a cushion layer made of the elastomer member, a sponge sheet, or the like may be provided below the base layer 22 as appropriate in order to adjust to the laying surface.

  Here, the size of the decorative tile, that is, the size of the base layer 22 is appropriately selected according to the laying purpose and location, and is about 40 to 60 cm square, for example. The thickness of the base layer 22 is appropriately 5 to 10 mm, although it depends on the size of the decorative tile and the familiarity with the laying surface. If it is too thin, the shape of the frame cannot be maintained, and it is difficult to ensure familiarity with the wall surface. Conversely, if it is too thick, the weight increases and problems in handling are likely to occur, and material costs are wasted.

  And the molding part 24 stuck and formed on the four sides of the base layer 22 holds the decoration forming member 10 composed of the cushion layer 14 and the rattan surface 12. It is easy to hold. Each molding part 24a can be expanded independently by the diagonal cuts (partition lines) 26 formed at the four corners of the cushion layer 14 in the molding parts 24 on each side. In addition, you may provide a cut | interruption in each center part of the molding part element of 4 sides.

  For this reason, the decoration forming member 10 can be easily attached to and detached from the tile frame 20 by hand. Moreover, even if it does not have the molding part 24 on all four sides, as long as the cushion layer 14 and the rattan surface 12 can be held, it may be provided on only two opposite sides. However, when it is provided on only two sides, it is necessary to finish it carefully so that the soles of the rattan slip will not get caught when walking.

As a forming material of the molding part 2, a plate member made of an elastically deformable synthetic resin, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyester (PET), polyamide (PA), polyacetal ( POM). In addition, the width | variety and thickness of a plate-shaped member are width: 10-20 mm, thickness: 0.5 when the external shape of a tile frame is the said 40-60 cm square size and a forming material is a plastic (synthetic resin), for example. ˜1 mm.
However, the molding part 24 can be formed of the above-described elastomer member, metal spring plate material, shape memory alloy, or the like as long as the molding part 24 can be elastically expanded without being limited to these materials. When using a metal material such as a metal spring plate material or a shape memory alloy, it is desirable to coat with rubber or resin from the viewpoint of the feeling of the sole.

  The holding cross-sectional shape of the holding wall (gripping wall) 24a of the molding part 24 is an upper cross-sectional curved eaves shape in the illustrated example, but is not limited to this, and any arbitrary shape such as a U-shaped cross-section or U-shape may be used. is there. From the standpoint of improving retainability, the opening of the molding part may be tapered (tapered). However, if the taper is too large, it is difficult to attach and detach the decoration forming member. The taper angle at this time is 5 to 30 °, preferably 10 to 20 °.

  At this time, the relationship between the opening height h of the holding wall 24a and the thickness t of the decoration forming member 10 is preferably 1 mm> th−h> 0 mm. If there is a gap between the thickness and the holding wall 24a, the decoration forming member 10 is likely to move in a sliding manner, and if the thickness is too thick, a problem is likely to occur in fitting workability.

  Further, the clearance α between the groove bottom formed by the holding wall 24a and the outer peripheral edge of the decoration forming member 10 is the outer periphery of the decoration forming member 10 in the gap formed when the decoration forming member 10 is held by the molding portion 24. The size of the direction is 2 to 10 mm, preferably about 3 to 5 mm. If it is too small, there is a possibility that the amount of elongation cannot be sufficiently absorbed. If it is too large, the decoration forming member 10 may move in one direction and a gap may be generated.

  The feature of the decorative tile according to the present invention is that the cushion layer 14 and the rattan table 12 can be detached from or attached to the tile frame. The cushion layer 14 can be removed after removing the rattan surface 12 while expanding the molding part 24 by hand.

  FIG. 3 is a perspective view showing an example when the decorative tile according to the present invention is laid. For example, when the decorative tile of the present invention is laid on the floor of a dressing room in a bathing facility, the rattan strips on the rattan table 12 extend when the rattan table 12 and the cushion layer 14 absorb moisture. At that time, the conventional decorative tile could not absorb the amount of elongation, and there was a problem that adjacent tiles interfered with each other and each tile swelled. The problem of swelling does not occur. This is because an elongation absorption gap is formed between the rising portion 20 of the molding and the cushion layer and the end of the rattan table, so that the amount of elongation can be absorbed.

It is a top view which shows one Embodiment of the decoration tile of this invention. FIG. 2 is a sectional view taken along line 2-2 of FIG. It is a top view which shows the example of laying the decoration tile of this invention. FIG. 4 is a cut perspective view taken along line 4-4 of FIG. 3.
