Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor having a cushioning property by laying a large number of unit-shaped carpets each formed into a square having a unit length (for example, about 50 cm) on one side like tiles. The present invention relates to a tile carpet set used for forming and the like.

[0002]

2. Description of the Related Art Conventionally, this kind of tile carpet is provided with an adhesive applied in advance to a back surface thereof at a production factory or the like in order to be able to lay the floor carpet easily and with good appearance.
There is known a configuration adopting a configuration in which the pressure-sensitive adhesive is fixed to a floor surface at a use site.

[0003]

However, conventionally, an adhesive is applied by dispersing unit shapes such as a square, a rectangle, a circle, and a line at regular intervals over the entire back surface of the tile carpet. Or, because it is applied in a continuous frame shape on the outer periphery of the back surface, in the former case, it is not possible to effectively prevent overdrying of the adhesive during storage, even though a large amount of adhesive is used. Adhesive strength of the outer peripheral part at the time of construction seems to be insufficient, and in the latter case the adhesive strength is sufficient, but when separating two pieces that are stored with the back sides overlapped during packing (2) Since the two pressure-sensitive adhesives are strongly adhered to each other in a continuous frame shape on the outer peripheral portion of the back surface, there is a problem that separation becomes difficult when the storage time is long.

[0004] In addition, due to the nature of distribution, this kind of product requires a long storage time from production to construction, and may take several years, so that the performance of the adhesive is inevitably reduced. In order to avoid a decrease in the performance of the pressure-sensitive adhesive and maintain the pressure-sensitive adhesive force over a long period of time, it was necessary to apply an expensive pressure-sensitive adhesive thickly.

The present invention has been proposed in view of the above-mentioned problems of the conventional tile carpet, and an object of the present invention is to reduce the amount of the adhesive to be applied while reducing the overdrying of the adhesive during storage. An object of the present invention is to provide a tile carpet set that prevents the two pieces from being separated at the time of construction, facilitates the separation of the two pieces at the time of construction, and can secure the adhesive strength of the outer peripheral portion required for fixing to the construction floor.

[0006]

In order to achieve the above object,
The present invention is a tile carpet set in which two tile carpets each having an adhesive applied to the back surface are stacked as a pair with the back surfaces overlapped, and the back surface of the pair of two tile carpets is provided. The adhesive applied to the adhesive is applied discontinuously along the periphery of the back surface, one by one, to form an adhesive-coated portion and a non-coated portion, and
When the sheets are overlapped, the coated part of the adhesive and the non-coated part overlap in a complementary relationship, and the coated part of the adhesive on the back surface of the two tile carpets slightly overlaps and continues in a strip shape. The entire periphery is surrounded by a frame, or the entire periphery is continuously formed in a band shape without overlapping so as to surround the entire periphery in a frame shape.

According to the present invention, as described above, the adhesive applied to the back surface of a pair of tile carpets is applied discontinuously along the periphery of the back surface for each sheet. Nevertheless, when the two tile carpets are superimposed, the adhesive application portions on the back surfaces of the two tile carpets slightly overlap each other and continuously surround in a strip shape, or surround the entire periphery in a frame shape, or Because it is coated and formed so as to surround the entire periphery continuously in a band shape without being adjacent to each other,
During storage, the application part of the mutual adhesive adheres complementarily to the non-application part on the other side, and the outer periphery of the two tile carpets is continuously surrounded in a frame shape over the entire periphery and sealed. This can prevent the adhesive from being excessively dried during storage, and can maintain the adhesive strength for a long period of time. Moreover, the application of the adhesive to the back surface of the two tile carpets is discontinuously applied and formed along the periphery of the back surface for each sheet. The coated portion and the non-coated portion overlap in a complementary relationship, and the coated portion of the adhesive on the back surface of the two tile carpets is adjacent to each other in a band shape without overlapping and surrounds the entire periphery in a frame shape. Because it is coated and formed so that it overlaps, or it is coated and formed so that it slightly overlaps and continuously forms a strip, it surrounds the entire circumference in a frame shape, so that two pieces can be easily separated at the time of construction Can be. Furthermore, although the adhesive is discontinuous, it is applied and formed along the periphery of the back surface of the tile carpet, so it is necessary to ensure sufficient adhesive strength of the outer peripheral portion required for fixing to the construction floor surface Can be.

[0008] The band width of the adhesive-applied portion on the back surface of the two tile carpets can be set in a range of 5 to 40 mm, and the adhesive-applied portion has two tiles. The present invention can be implemented in a form in which the coating is formed 5 to 10 mm inside the outermost peripheral portion of the carpet. With this configuration, the above object can be achieved without the need to use an extra adhesive.

Further, by mixing a foaming agent into the application portion of the pressure-sensitive adhesive, not only can the amount of the pressure-sensitive adhesive be reduced without changing the coating thickness, but also the pressure-sensitive adhesive inside the pressure-sensitive adhesive after drying is applied. Has a large number of air bubbles and improves cushioning properties.Moreover, a large number of small recesses are formed on the surface of the pressure-sensitive adhesive, which can exert a suction effect on a construction floor having a smooth surface. .

BRIEF DESCRIPTION OF THE DRAWINGS It is a back view of a set of two tile carpet which shows an Example.

In FIGS. 1A, 1B and 3C to 3A and 3B, 1 is a first tile carpet having a square shape, and 2 is a second tile carpet having the same size. The tile carpet 3 is a portion to which an adhesive is applied, and 4 is a non-application portion. The first tile carpet 1 and the second tile carpet 2 have the same configuration. For example, the fiber web is needled on the surface side of the base fabric to form a nonwoven fabric, or piled and raised. , Other,
It is to be understood that the base cloth has various configurations, and that the back surface of the base cloth has a known structure such as a backing material fixed thereto.

In the first embodiment shown in FIG. 1, an adhesive-coated portion 3 and a non-coated portion 4 are formed along the periphery of the back surface 1a of the first tile carpet 1 and the back surface 2a of the second tile carpet 2. Are alternately formed with a length obtained by equally dividing the four sides of the square into two (the length obtained by equally dividing the peripheral edge into eight), and both have the same pattern. The application section 3 at the four corners is 45
It is preferable to be inclined at an angle. By doing so, when the back surface 1a of the first tile carpet 1 and the back surface 2a of the second tile carpet 2 are overlapped, as can be understood from FIG. Part 3
Although the and the non-coating portion 4 are formed discontinuously, they are made to correspond to each other in a complementary relationship, and adhere to each other in the adhesive coating portion 3 over the entire periphery of the outer peripheral portion. Can be sealed.

FIG. 2 shows a second embodiment of the present invention, in which an adhesive-coated portion 3 and a non-coated portion 4 are formed along the periphery of the back surface 1a of the first tile carpet 1 and the back surface 2a of the second tile carpet 2. Is the length obtained by dividing the four sides of the square into four (the periphery is 16
This is a case where the same pattern is formed alternately, and both are formed in the same pattern. The coating portions 3 at the four corners are 4
Preferably, it is inclined at 5 degrees. In this way, when the back surface 1a of the first tile carpet 1 and the back surface 2a of the second tile carpet 2 are overlapped, both the coated portion 3 and the non-coated portion 4 of the adhesive are discontinuously formed. In spite of this, they can be made to correspond to each other in a complementary relationship, and can be sealed to each other by the adhesive application section 3 over the entire outer periphery.

In the third embodiment shown in FIG. 3, the adhesive-coated portion 3 and the non-coated portion 4 are formed along the periphery of the back surface 1a of the first tile carpet 1 and the back surface 2a of the second tile carpet 2. Are alternately formed with the length of four sides of the square (the length of the perimeter divided into four equal parts), and both patterns are rotated by 90 degrees to correspond. In addition, the coating portion 3 at the four corners
Is preferably inclined at 45 degrees. In this way, when the back surface 1a of the first tile carpet 1 and the back surface 2a of the second tile carpet 2 are overlapped, both the coated portion 3 and the non-coated portion 4 of the adhesive are discontinuously formed. In spite of this, they can be made to correspond to each other in a complementary relationship, and can be sealed to each other by the adhesive application section 3 over the entire outer periphery.

The arrangement and formation pattern of the coated portion 3 and the non-coated portion 4 of the pressure-sensitive adhesive may be other than the above embodiments. For example,
The two sides of the square may be alternately formed (not shown) so as to extend over an L-shape (the length of the perimeter divided into two equal parts).

In short, the adhesive applied to the back surfaces 1a and 2a of the pair of tile carpets 1 and 2 is
a, applied discontinuously along the periphery of 2a to form an adhesive-applied portion 3 and a non-applied portion 4 for each sheet. The application part 3 of the agent and the non-application part 4 overlap in a complementary relationship, and
The adhesive-applied portions 3 on the back surfaces 1a and 2a of the two tile carpets 1 and 2 slightly overlap each other to continuously form a band shape and surround the entire periphery in a frame shape, or to be adjacent to each other without overlapping. What is necessary is just to apply | coat and form so that the whole circumference may be surrounded in a frame shape continuously in a belt shape.

Also, the two tile carpets 1, 2
The band-like width of the adhesive application portion 3 on the back surfaces 1a and 2a of
Preferably, it is in the range of ４０40 mm. If the thickness is 5 mm or less, the adhesive strength required at the time of construction will be insufficient, and if it is 40 mm or more, the amount of the adhesive will be excessive. Further, the adhesive application section 3
Is 5 from the outermost periphery of the two tile carpets 1 and 2.
It is preferable to form a coating on the inner side of 10 mm. By doing so, it is not necessary to use an extra adhesive, and it is possible to prevent the adhesive from leaking out. In addition, when the inner side is 10 mm or more, there is a possibility that the peripheral edge is curled up, which is not preferable. Further, the application pattern of the adhesive application section 3 is as follows:
It may be rectangular, elliptical, or any other shape.

Further, in applying the pressure-sensitive adhesive, for example, a foaming agent may be mixed in the pressure-sensitive adhesive coating portion 3 so that an appropriate coating layer thickness can be obtained even with a small application amount. As a means for this, the pressure-sensitive adhesive is foamed in advance by a foaming machine to 2 to 3 times (volume ratio) with a foaming machine, or air is mixed with the pressure-sensitive adhesive during the coating to form a foam. The application means is
Although various types can be adopted, for example, screen printing, letterpress, intaglio, etc. can be adopted in order to apply in an accurate pattern.

It is preferable to use a pressure-sensitive adhesive of a type which can be peeled repeatedly. The first tile carpet 1 and the second tile carpet 2 are applied in advance in a factory using such an adhesive in a manner as in the above-described embodiment, and dried so as not to be transferred to the other side. One or more sets are packed, boxed and packed, stored, transported, sold for sale, separated and laid and used at the site of use as a set of two sheets in which the back sides are directly polymerized back to back.

[0020]

According to the present invention, the adhesive applied to the back of a pair of tile carpets is formed discontinuously along the periphery of the back for each sheet. Nevertheless, when the two tile carpets are superimposed, the adhesive application portions on the back surfaces of the two tile carpets slightly overlap each other and continuously surround in a strip shape, or surround the entire periphery in a frame shape, or Because it is coated and formed so that it does not overlap and continuously surrounds the entire band in a frame shape,
During storage, the application part of the mutual adhesive adheres complementarily to the non-application part of the other side, and the outer periphery of the two tile carpets is continuously surrounded in a frame shape over the entire periphery and sealed. This can prevent the adhesive from being excessively dried during storage, and can maintain the adhesive strength for a long period of time. Moreover, the application of the adhesive to the back surface of the two tile carpets is discontinuously applied along the periphery of the back surface for each sheet. The coated portion and the non-coated portion overlap in a complementary relationship, and the coated portion of the adhesive on the back surface of the two tile carpets is adjacent to each other without overlap and continuously surrounds the entire frame in a frame shape. Since it is coated and formed so as to be overlapped with each other or is continuously formed in a band shape so as to surround the entire periphery in a frame shape, two pieces can be easily separated at the time of construction. Furthermore, although the adhesive is discontinuous, it is applied and formed along the periphery of the back of the tile carpet, so it is necessary to ensure sufficient adhesive strength of the outer peripheral portion required for fixing to the construction floor surface Can be.

The band width of the adhesive-applied portion on the back surface of the two tile carpets is in the range of 5 to 40 mm, and the adhesive-applied portion is 5 to 10 mm from the outermost peripheral portion.
The above-described object can be achieved without the need to use an extra pressure-sensitive adhesive by performing the coating in the form of being formed on the inner side of mm.

Further, by mixing a foaming agent into the adhesive application section, not only can the amount of the adhesive be reduced without changing the coating thickness, but also the inside of the adhesive after application and drying is formed. Has a large number of air bubbles and improves cushioning properties.Moreover, a large number of small recesses are formed on the surface of the pressure-sensitive adhesive, which can exert a suction effect on a construction floor having a smooth surface. .
