Description

  The present invention relates to a tile carpet with an exchange sign and a tile carpet floor with an exchange sign, and more particularly, a part of the tile carpet surface is coated with a contaminant resistant material that prevents or delays the contamination of the tile carpet surface. A tile carpet with a replacement sign characterized by having been applied, and a tile carpet with a replacement sign in which a part of the surface of the tile carpet is coated with a stain-resistant material that prevents or delays contamination of the surface of the tile carpet. A tile carpet floor with an exchange sign characterized by covering the floor surface of the tile carpet surface with a part of or the entire surface of the tile carpet, and a coating of a contaminant resistant material that prevents or delays the contamination of the tile carpet surface. Tiled carpet on the entire surface and the above stain resistance Relates tile carpet floor with replacement sign, characterized in that it has Kutsugae設 the floor with both tile carpets not subjected to coating with materials.

  2. Description of the Related Art Conventionally, a construction method called a tile carpet, in which a floor surface is formed by laying a rectangular carpet having a side of about several tens of centimeters on the floor surface, is generally performed. A tile carpet is usually formed by heat-welding a fiber portion of a surface layer of a pile fabric or the like to a base layer made of vinyl chloride or synthetic rubber, and has a rectangular shape with a side of about several tens of centimeters. The floor surface is formed by simply placing or bonding to the floor surface sequentially so that there is no gap, so it is very simple and does not require special techniques for construction, so it is the floor surface of offices, stores, and homes. Widely used in interiors.

  The appearance of a very common tile carpet TC is as shown in FIG. 13a. A longitudinal section thereof is shown in FIG. 13b. As shown in FIGS. 13a and 13b, the tile carpet TC is formed by thermally welding a surface layer S made of fibers F such as pile fabric to a base layer B made of vinyl chloride, synthetic rubber or the like. The lower end portion of the fiber FA of the surface layer S is usually planted on a base fabric BF made of a nonwoven fabric or the like, and the lowermost end portion of the fiber FA located below the base fabric BF is thermally welded to the base layer B together with the base fabric BF. As a result, the surface layer S and the base layer B are irreversibly fixed to form the whole.

  The greatest feature of the tile carpet having such a configuration is that the impression of the entire floor can always be kept clean and aesthetic by exchanging only a heavily soiled portion with a new or cleaned product. That is, in the case of ordinary carpets, a width of about 90 cm to several meters is purchased in a wound state and laid while cutting the details according to the shape of the floor. Even if it became dirty, it was not possible to replace only that part. Therefore, it is possible to cope with the method by cleaning while laying, but if the dirt is severe, it remains as a stain, and the appearance is extremely unsightly. Furthermore, the labor required for the cleaning is also great.

In general, the floor of the room is not uniformly polluted as a whole, and the contamination progresses in advance at entrances and around desks where many people pass. In particular, in stores and facilities where a large number of unspecified people enter and leave on foot, the difference in dirt on the entire floor becomes large. However, with normal carpets, it is not possible to replace only a place with a lot of dirt, so there was only a means of cleaning or replacement, but in the case of a tile carpet floor laid with tile carpet, one side is about several tens of centimeters. Since the configuration is such that the units are continuously laid, it is only necessary to replace the heavily contaminated portion, which is extremely simple and economical.

In addition, various techniques have been publicly disclosed as measures for preventing contamination of carpets, and a part of them is as described in Patent Documents 1 to 3 below. That is, in “Patent Document 1” of the following Patent Document 1, a method of imparting water repellency to the original yarn itself is disclosed. In “Carpet Manufacturing Method”, a method of antifouling processing at the stage where fibers are planted on a base fabric is disclosed. Further, in the following “Patent Document 3,“ Method for imparting stain resistance to fiber surface having different dyeability and article produced thereby ”, an antifouling agent for finished carpets (including tile carpets) A method of imparting antifouling properties by applying a coating is disclosed. Furthermore, at present, water- and oil-repellent treatment agents that can easily form a fluororesin film on the fiber surface simply by applying with a brush and can be dried at room temperature are also commercially available. It was also possible to apply processing. Patent Document 4 below is an example of a system that detects pressure and moisture and notifies the mat replacement time.

  As described above, methods for imparting water repellency and antifouling properties to carpets are already known and are frequently used. However, carpets carrying water repellency and antifouling properties in this way are inevitably expensive compared to normal products, and the water repellency and antifouling properties are not perfect, and the dirt becomes worse. This necessitates cleaning and replacement. In addition, once cleaning is performed, the coating layer on the fiber surface is also peeled off, resulting in a problem that water repellency and antifouling properties are significantly reduced. Furthermore, in terms of cost, labor costs required for cleaning and replacement cannot be ignored. That is, since special techniques are required for cleaning and replacement of carpets, the cost required for this is a cost that cannot be ignored.

  However, the unit price per tile carpet is extremely low. Therefore, when covering large floor areas such as in stores and facilities, water repellency and antifouling are better than methods of laying carpets with water repellency and antifouling properties and maintaining aesthetics through cleaning and replacement. The method of laying a normal tile carpet that does not have a characteristic and replacing only the severely dirty part is much cheaper in terms of cost, so the number of shops and facilities that use tile carpets and general households also increase. It's getting on. As mentioned above, tile carpets are simply placed or glued on the floor, so they are very easy to replace, even for non-technical, facility staff, store employees, or homewives. Can be done.

  When replacing regular carpets, all equipment, furniture, and furniture are removed, and large-area carpets are laid accurately, and the surrounding area is accurately cut according to the shape of the pillars and walls. Therefore, advanced technical skills are required. However, in the case of tile carpets, the parts underneath the equipment, furniture and furniture are not passed by people and are not soiled, so there is no need for replacement. Therefore, replacement can be performed with the equipment, furniture, and furniture arranged. In addition, there is no need for replacement because people cannot pass through the pillars and walls. Therefore, it is necessary to replace only the place where it is easy to peel off and lay, so that it does not require an expert, and this aspect also has a great role in saving costs.

  Thus, although it is a simple and inexpensive tile carpet, there exists a problem that it is unexpectedly difficult to clarify the replacement time. For example, if a part of a beverage spilled is extremely dirty, you can clearly see it, but you can replace it immediately. Therefore, it is difficult to determine at what point in time and in which range of tile carpets should be replaced.

  For example, when a tile carpet is laid at home, no problem arises because the replacement time can be determined by consultation with the family. However, in stores and facilities, the cleanliness and aesthetics of the floor surface become a major problem that is also related to the user's awareness and the purchase motivation of customers. In other words, in facilities such as hotels and rental venues, the floor is the most visible part of the user entering the facility, so the floor, especially where the floor near the entrance is unclean, must be used. It tends to make a bad impression on the person. In stores, the cleanliness and aesthetics of the floor have a great influence on buyers' willingness to purchase. In particular, if the floor is dirty in stores that handle food items, restaurants, and stores where hygiene concepts are a major factor, such as barbers and beauty shops, it can give a fatal impression to people who enter the store. It will be. From this point, large-scale retail stores that mainly handle foods have made manuals for maintaining the cleanliness of the floor surface, and there are some places that always maintain a certain level of cleanliness and aesthetics.

  However, when tile carpets are used on the floor, the replacement period and range are all up to the facility staff and store clerk. There is no good guideline. Employees and shop assistants who are accustomed to seeing the same floor every day can hardly recognize the dirt that accumulates little by little every day, and as a result, there are not a few cases where they are left in a state where the dirt is extremely bad. . However, facility users and store customers do not look at the floor of the facility or store every day, so at the moment they enter the facility or store, they are sensitive to dirt that is not noticed by staff and store staff. It is also possible.

  In the case where a part of the tile carpet on the floor of an individual store is dirty, it is the store owner who will suffer the disadvantage, so it can be done by self-responsibility, but public facilities and large-scale retailers In places used by many people such as shops, floor dirt is a source of discomfort for many people, and it also leads to disadvantages for many people who work there. In addition, in so-called chain stores or franchise stores such as family restaurants and convenience stores, the problem is even more serious. For example, if the floor is dirty at one particular store, It will also deteriorate the overall image of the chain store, including other stores. Therefore, in such a store having many stores under the same brand, it is necessary to maintain the cleanliness and beauty of the floor at a certain level or higher in any store of the same brand.

  That is, the floor must be maintained at a certain level of cleanliness and aesthetics, regardless of where the customer enters the store. However, if the timing and range of tile carpet replacement is left to the judgment of the store staff at each store, the degree of cleanliness and aesthetics are highly dependent on the subjectivity of the individual. It is not possible to maintain this. In addition, there is a method of patroling each store by setting a position like a patrolman and determining the replacement timing and range of tile carpet, but if the number of stores increases, there is also a range that can be visited by one patrolman However, if the number of patrolmen is limited, the problem of how to unify the subjectivity of the patrolmen will arise. Therefore, there is a need for a method that objectively determines the tile carpet replacement period and range as much as possible while eliminating as much individual subjectivity as possible.

  In the previous patent document 4, although it is not a tile carpet, the degree of dirt on the mat (entrance mat as an example) is detected by pressure (how many steps the person steps on) and moisture (when there is a lot of moisture, the dirt gets faster), There is disclosed a “replacement loan product and loan product exchange support system” which issues a replacement request signal when the dirt becomes more than a certain level. Certainly, if such a method is used, the replacement time can be determined by a somewhat objective method. However, in the previous patent document 4, a complicated configuration of detection means such as a pressure sensor and a moisture sensor, a wireless transmission unit, a reception unit, a signal processing unit, and a battery is used. However, it is almost impossible to incorporate such a complicated configuration, and even if it is possible, it becomes expensive in cost and cannot be adopted in reality. Unlike tiles that only need to be installed at one entrance, such as entrance mats, in the case of tile carpets that are laid on the entire floor of a facility or store, a means for detecting the degree of contamination is provided at the required locations on the floor. If the floor area is large or the number of stores is large, it will be a great expense. Therefore, there is a demand for a configuration that can objectively determine the replacement timing and the number of tile carpets using simple and inexpensive means without using such a complicated and expensive configuration.

From the above, the problems to be solved by the present invention are summarized as follows.
<Problem 1>
To develop a tile carpet and a tile carpet floor on which such tile carpets are laid down so that the timing and range of replacement of tile carpets can be determined as objectively as possible without judgment based on individual subjectivity.
<Problem 2>
The appearance of the tile carpet and the tile carpet floor is the same as that of a normal tile carpet and a tile carpet floor. That is, the method of increasing the thickness of the tile carpet or changing the appearance by incorporating various devices is not adopted.
<Problem 3>
As a means for detecting the replacement timing of the tile carpet, a simple and inexpensive means is used as much as possible, avoiding a complicated and expensive method using a sensor or electronic signal processing.

The present invention has been made to solve the above-described problems, and provides the means for solving the problems described below.
<Solution 1>
A tile carpet with an exchange sign, characterized in that a part of the surface of the tile carpet is coated with a stain-resistant material that prevents or delays the contamination of the surface of the tile carpet.
<Solution 2>
The floor surface is covered with a part of or the entire surface of a tile carpet with an exchange sign that has been coated with a part of the surface of the tile carpet to prevent or delay contamination of the surface of the tile carpet. Tile carpet floor with exchange signage characterized by.
<Solution 3>
Cover the floor using both tile carpets that have been coated with a stain resistant coating that prevents or delays the surface of the tile carpet surface, and tile carpets that have not been coated with the above-mentioned stain resistant materials. Tile carpet floor with exchange signage characterized by.
<Solution 4>
The tile carpet with an exchange sign according to Solution 1, wherein the contaminant is a photocatalyst, an antifouling agent, or a water repellent.
<Solution 5>
The tile carpet floor with an exchange sign according to Solution 2 or Solution 3, wherein the contaminant is a photocatalyst, an antifouling agent, or a water repellent.

  According to Solution 1 and Solution 2 of the present invention, a part of the surface of the tile carpet is coated with a contamination-resistant substance that prevents or delays contamination. Other parts except the part are fouled, but the coating part is kept in the initial state or close to the original state. As a result, the coating portion is visually differentiated from the surroundings over time, and clearly comes out, so that this coating portion functions as a sign indicating the arrival of the tile carpet replacement period.

  Further, according to the invention of Solution 1 and Solution 2 of the present invention, since a part of the surface of the tile carpet is only coated with a contamination-resistant substance that prevents or delays the contamination, the appearance of the tile carpet and the tile carpet floor Is exactly the same as the appearance of normal tile carpets and tile carpet floors. Since various devices are not incorporated, the thickness of the tile carpet itself does not increase or the appearance does not change at all.

  Further, according to the solutions 1 and 2 of the present invention, the sign notifying the replacement timing of the tile carpet forms a coating film on the surface of the tile carpet with a contamination-resistant substance that prevents or delays contamination. Since no sensor or electronic signal processing device is used, it is extremely simple and inexpensive, and does not break down like the sensor or electronic signal processing device, and does not require any equipment maintenance. Accordingly, the invention of Solution 1 and Solution 2 of the present invention can be adopted with a small cost and effort even in a company having a facility or store having a large floor, or a large number of chain stores or franchise stores. is there.

  In the inventions of Solution 1 and Solution 2 of the present invention, as described above, the tile carpet replacement time is clarified by the sign. In addition, regarding the determination of the exchange range, it is most appropriate to apply the principle of exchanging adjacent eight tile carpets, that is, a total of nine tile carpets around the tile carpet where the sign appears. . That is, even if the surrounding eight tile carpets do not have the sign, it is determined that a certain amount of dirt is accumulated as long as they are adjacent to the tile carpet having the sign. is there. In addition, even if the tile carpet is adjacent to the tile carpet having the sign, the tile carpet on which the equipment, furniture, and furniture are placed can be excluded from the object of replacement in principle. This is because, as described above, the contamination of the tile carpet occurs in places where people pass.

  Next, according to the invention of Solution 3 of the present invention, a tile carpet in which a coating film is formed on the entire surface of one tile carpet with a contamination-resistant substance that prevents or delays contamination (hereinafter referred to as a "signed tile carpet"). It has been shown that a tile carpet floor having the same effect as that of the solution 2 can be realized even when using. That is, in the case of the invention of the solution means 3, the tile carpet of the signature specification itself functions as a sign for notifying the replacement time. In other words, by installing sign-type tile carpets at the necessary points of tile carpets laid on the floor, even if the tile tile carpets of normal signs become dirty over time, Since the progress of the fouling is delayed, the sign-type tile carpet itself is visually raised from the normal tile carpet and becomes conspicuous, thereby notifying the time for replacement. Even in this case, it is appropriate to replace nine tile carpets including eight adjacent tile carpets as the replacement range.

  Subsequent solution means 4 and 5 make it clear that the pollutant is a photocatalyst, antifouling agent or water repellent. The photocatalyst is titanium dioxide as is well known, and has the ability to finally decompose the organic substance into carbon dioxide and water when exposed to light. Therefore, if the coating layer by the photocatalyst is formed on the surface fiber portion of the tile carpet, only that portion is prevented from being contaminated by the organic substance, or the contamination is delayed.

  Next, as an antifouling agent for fibers, those using a fluororesin coating are widely known, and already marketed as products for carpet maintenance. By using such an antifouling agent, if a coating layer made of fluororesin is formed on the surface fiber portion of the tile carpet, only that portion is prevented from fouling or fouling is delayed. In addition, as the water repellent, fluororesin-based, paraffin wax-based, or silicon-based ones are known, and if a coating layer is formed of these, only that portion is fouled (water is used as a medium). Fouling), or fouling is delayed.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

  FIG. 1 a is a plan view of a tile carpet 1 with an exchange sign according to the first embodiment. S1 is a surface layer made of fibers, and a coating film C1 made of a contamination-resistant substance is formed on a part of the surface layer S1. The shape F1 of the coating film C1 is circular. Since the coating film C1 is transparent, it is not visually visible as shown in FIG. 1b. Therefore, when the tile carpet 1 with an exchange sign is new, the tile carpet 1 with an exchange sign looks like a normal tile carpet TC (see FIG. 13a) as shown in FIG. 1b.

  However, as the stain on the surface layer S1 of the tile carpet 1 with an exchange sign progresses as time passes, the portion of the coating film C1 where the stain is difficult to progress rises visually and becomes conspicuous. That is, the circular shape F1 is visually recognized in a part of the surface layer S1. This circular shape F1 functions as a sign for notifying the replacement timing of the tile carpet.

  FIG. 6 is a schematic plan view showing a floor surface FL of a convenience store CS in which a tile carpet 1 with an exchange sign is arranged at a necessary point of a normal tile carpet TC. That is, the floor FL of the convenience store CS is the “tile carpet floor with exchange sign” described in the solution 2. In FIG. 6, E is an entrance / exit, CU is a counter, BK is a back space, WC is a toilet, and SW1 to SW6 are merchandise display shelves. The tile carpet 1 with an exchange sign is disposed every other sheet in the x and y directions in the flow line portion of the customer on the floor surface FL. The direction may be every other two, conversely every two in the x direction, every other in the y direction, or every two in the x and y directions. Furthermore, it is natural to adopt a completely different arrangement method. That is, the arrangement method of the normal tile carpet TC and the tile carpet 1 with the exchange sign can be arbitrarily determined.

  In FIG. 6, since the normal tile carpet TC and the tile carpet 1 with an exchange sign are both in a new state, the coating film C1 is visually invisible. That is, the floor FL of the convenience store CS is in a state that is not visually different from the case where a normal tile carpet TC is laid on the entire surface.

  FIG. 7 shows a state where the floor surface FL of the convenience store CS has become dirty with the passage of time. In the state of FIG. 7, the coating film C <b> 1 is clearly lifted and visually recognized in the tile carpet 1 with the exchange sign where the dirt is conspicuous, but the coating film C <b> 1 is visible in the tile carpet 1 with the exchange sign with almost no dirt. The difference between the tile carpet 1 with an exchange sign and the normal tile carpet TC does not occur in this portion. Therefore, it is determined that it is time to replace the tile carpet 1 with an exchange sign from which the coating film C1 is visually recognized and the normal tile carpet TC adjacent thereto.

  FIG. 8 shows the exchange ranges CA1 and CA2 of the tile carpet 1 with an exchange sign and the normal tile carpet TC adjacent thereto in the state of FIG. It is determined that it is necessary to exchange the tile carpet 1 with the exchange sign in the range surrounded by the thick broken line and the normal tile carpet TC adjacent thereto. Various methods are conceivable for determining the replacement ranges CA1 and CA2. However, the replacement ranges CA1 and CA2 shown in FIG. 8 can be obtained if there is one tile carpet 1 with an exchange sign in which the coating film C1 is visible. The total of nine tile carpets including eight normal tile carpets TC adjacent thereto is exchanged. If there is a tile carpet 1 with an exchange sign in which the coating film C1 can be visually recognized, it is natural that it is natural that the adjacent normal tile carpet is somewhat contaminated. It is thought that this is appropriate.

  However, in FIG. 8, the tile carpet tc on which the counter CU and the display shelves SW1 to SW6 are placed is removed from the replacement ranges CA1 and CA2. Since dirt on the floor surface FL is mainly caused by human traffic, the progress of dirt is naturally slow in the tile carpet tc on which the counter CU and the display shelves SW1 to SW6 are placed. Is excluded from the exchange ranges CA1 and CA2.

  In FIG. 1c, how much the coating film C1 is visually recognized can be determined by a manual as to whether or not it is determined that it is the replacement time. That is, if the transition from the state of FIG. 1b to the state of FIG. 1c is recorded by a continuous photograph and the stage at which the convenience store CS determines that it is time for replacement is determined manually in advance. good. In this way, each store can judge the replacement time by comparing the manual photo with the state of the site, so the replacement time does not vary from store to store, and the arbitraryness of each store clerk is eliminated. It is possible to judge the replacement time based on objective criteria. In addition, since the replacement ranges CA1 and CA2 can also be determined manually, an objective judgment can be made regarding this.

  FIG. 9 shows a case in which the state of dirt on the floor surface FL changes due to a change in the product configuration stored in the display shelves SW1 to SW6 in the convenience store CS. Even in this case, if the exchange ranges CA3 and CA4 are shown based on the same principle as in FIG. 7, the result is as shown in FIG.

  FIG. 2 a is a plan view of the tile carpet 2 with an exchange sign according to the second embodiment. S2 is a surface layer made of a fiber, and a coating film C2 made of a contamination-resistant substance is formed on a part of the surface layer S2. The shape F2 of the coating film C2 is linear. Since the coating film C2 is transparent, it is not visually visible as shown in FIG. 2b. Therefore, when the tile carpet 2 with an exchange sign is new, the tile carpet 2 with an exchange sign looks like a normal tile carpet TC (see FIG. 13a) as shown in FIG. 2b.

  However, as the stain on the surface layer S2 of the tile carpet 2 with the exchange sign progresses over time, the portion of the coating film C2 where the stain hardly progresses visually rises and becomes conspicuous. That is, the linear shape F2 is visually recognized in a part of the surface layer S2. This linear shape F2 functions as a sign for notifying the replacement timing of the tile carpet. The arrangement method and replacement range of the tile carpet 2 with an exchange sign are substantially the same as those in the first embodiment.

  FIG. 3 a is a plan view of the tile carpet 3 with an exchange sign according to the third embodiment. S3 is a surface layer made of fiber, and coating films C3,... C3,. The shape F3 of the coating film C3,... C3,... Is configured so as to form a character “CHANGE”. Since the coating films C3,... C3,... Are transparent, they are not visually visible as shown in FIG. Therefore, when the tile carpet 3 with an exchange sign is new, the tile carpet 3 with an exchange sign looks like a normal tile carpet TC (see FIG. 13a) as shown in FIG. 3b.

  However, as the stain on the surface layer S3 of the tile carpet 3 with an exchange sign progresses over time, the portions of the coating film C3,... C3,. That is, the character shape F3 “CHANGE” is visually recognized in a part of the surface layer S3. The shape F3 of the character “CHANGE” functions as a sign for notifying the replacement timing of the tile carpet. The arrangement method and the exchange range of the tile carpet 3 with an exchange sign are substantially the same as in the first embodiment, but the coating film C3,... C3,... Is wider than the coating film C1 in the first embodiment and is called CHANGE. Since the character shape F3 also has the meaning that “replacement is necessary”, as a sign for prompting the replacement, it is more persuasive than the circular shape F1 of the first embodiment and the linear shape F2 of the second embodiment. Have.

  FIG. 4 a is a plan view of the tile carpet 4 with an exchange sign according to the fourth embodiment. S4 is a surface layer made of a fiber, and coating films C4a, C4b, C4c, and C4d made of a contamination resistant material are formed on a part of the surface layer S4. The shape F4a of the coating film C4a is configured so as to form a slightly uneasy face on the square outline as a whole. Further, the shape F4b of the coating film C4b is configured so as to form the letters “nearly” as a whole. Further, the shape F4c of the coating film C4c is configured to form a face with a crying expression on the outline of the square as a whole, and the shape F4d of the coating film C4d as a whole forms the letters “Please change”. It is configured.

The coating films C4a and C4b are formed thicker and the coating films C4c and C4d are formed thinner. Since the coating films C4a, C4b, C4c, and C4d are transparent, they are not visually visible as shown in FIG. 4b. Therefore, when the tile carpet 4 with an exchange sign is new, the tile carpet 4 with an exchange sign looks like a normal tile carpet TC (see FIG. 13a) as shown in FIG. 4b.

  However, as the stain on the surface layer S4 of the tile carpet 4 with an exchange sign progresses over time, the coating films C4a and C4b where the coating is thick and the stain hardly progresses are visually lifted and become conspicuous (see FIG. 4c). That is, an uneasy face shape F4a and a character shape F4b of "Soon" are visually recognized on a part of the surface layer S4, and functions as a sign for notifying that the replacement timing of the tile carpet is approaching. When the stain on the surface layer S4 of the tile carpet 4 with the exchange sign progresses further as time elapses, the thin coating films C4c and C4d are also visually raised and become conspicuous (see FIG. 4d) and crying. The face shape F4c and the character shape F4d of “Change” are informed that the time for replacing the tile carpet 4 has arrived.

In this way, a sign that can be notified in two stages can be formed by a combination of the coating films C4a and C4b and the coating films C4c and C4d with the coating thickness changed. The arrangement method and the exchange range of the tile carpet 4 with an exchange sign are substantially the same as those in the first embodiment.

  In the tile carpet 5 of Example 5 shown in FIG. 5a, a coating film C5 made of a contamination-resistant substance is formed on the entire surface S5. Since the coating film C5 is transparent, the appearance is not different from that of a normal tile carpet TC (see FIG. 13a). If the tile carpets TC, TC,... Are laid around the tile carpet 5 so as not to open a gap, the state shown in FIG. In FIG. 5b, both the tile carpet 5 and the normal tile carpets TC, TC,... Are in a new state, and thus there is no apparent difference between them, and the whole is laid with one type of tile carpet. The formed floor surface fl is formed.

However, when the stain on the floor surface fl progresses with time, the tile carpet 5 formed with the coating film C5 and the ordinary tile carpets TC, TC,... Having no coating film as shown in FIG. The difference becomes noticeable and the tile carpet 5 is visually differentiated from the tile carpets TC, TC,. That is, the tile carpet 5 itself functions as a sign for notifying the replacement time.

FIG. 11 is a schematic plan view showing the floor surface FL of the convenience store CS in which the tile carpet 5 is disposed at a required place. In FIG. 11, all parts other than the tile carpet 5 are the normal tile carpet TC ( The code is attached only to a part). That is, the floor FL of the convenience store CS is the “tile carpet floor with exchange sign” described in the solution means 3, and the “exchange sign” here refers to the tile carpet 5 itself. The tile carpets 5 are arranged every other piece in the x and y directions in the flow line portion of the customer on the floor surface FL, but this is an example of an arrangement method, and different arrangement methods are used. Of course, it is also free to adopt.

  In FIG. 11, since the normal tile carpet TC and the tile carpet 5 are both new, the coating film C5 is invisible. That is, the floor FL of the convenience store CS is in a state that is not visually different from the case where a normal tile carpet TC is laid on the entire surface.

  FIG. 12 shows a state where the floor surface FL of the convenience store CS has become dirty with the passage of time. In the state of FIG. 12, the tile carpet 5 is clearly differentiated and visually recognized by the action of the coating film C5 in the portion where the stain on the floor surface FL is conspicuous. There is no difference in tile carpet TC. Therefore, it is determined that it is time to replace the tile carpet 5 that has been differentiated from the surroundings and visually recognized and the normal tile carpet TC adjacent thereto.

  A portion surrounded by a thick broken line in FIG. 12 shows the replacement ranges CA5 and CA6 of the tile carpet 5 and the normal tile carpet TC adjacent thereto. Various methods are conceivable for determining the replacement ranges CA5 and CA6, but the replacement ranges CA5 and CA6 shown in FIG. 12 are different from the surroundings if there is one tile carpet 5 that can be visually recognized. This is determined by the principle of replacing a total of nine tile carpets including eight normal tile carpets TC adjacent thereto, and this principle is the same as that of the first embodiment. Also, the tile carpet tc on which the counter CU and the display shelves SW1 to SW6 are placed is removed from the replacement ranges CA5 and CA6 as in the first embodiment.

  In FIG. 5c, how much the coating film C5 is visually recognized can be determined by manual as in the case of the first embodiment. In other words, if the transition from the state of FIG. 5b to the state of FIG. 5c is recorded by a continuous photograph and the stage at which the convenience store CS determines that it is time for replacement is determined manually in advance. good. In this way, each store can judge the replacement time by comparing the manual photo with the state of the site, so the replacement time does not vary from store to store, and the arbitraryness of each store clerk is eliminated.
