Description

  The present invention relates to a tile carpet used by being arranged side by side so as to stick tiles on a floor, and more particularly to a tile carpet having air holes for air to pass through in the thickness direction.

  An example of a conventional tile carpet is shown in FIG. 9 (first conventional tile carpet). This figure is a partially enlarged sectional view showing a part of a breathable support floor 4 on which a conventional tile carpet 2 is placed. As shown in the figure, the air-permeable support floor 4 has a plurality of air holes 6 (see, for example, Patent Document 1).

  The conventional tile carpet 2 has a two-layer structure including a carpet layer 12 and a backing layer 10. The carpet layer 12 of the tile carpet 2 is constituted by, for example, a carpet in a state in which fibers constituting the carpet are substantially planted on a sheet material having air permeability in the thickness direction. The above sheet material is affixed to the upper surface of the backing layer 10 with an adhesive that is partially applied. Thus, the tile carpet 2 has air permeability in the thickness direction.

  The backing layer 10 of the tile carpet 2 is formed by pulverizing a large number of irregularly shaped urethane rubber chips having a particle diameter of about 2 mm to about 5 mm, and applying them to the surface of the chips in advance. The urethane resin binder was melted by heating, and the chips were adhered to each other through the melted binder, so that voids were formed between the irregularly shaped chips.

  According to the tile carpet 2 and the breathable support floor 4 on which the tile carpet 2 is placed, in a room where they are laid, the tile carpet 2 communicates with a space below the breathable support floor 4 (not shown). By installing the air duct or the like, the air adjusted in temperature or the like sent from the air duct (not shown) or the like is used as the air vent 6 of the air-permeable support floor 4 and the thin air vent of the carpet layer 12 of the tile carpet 2. The indoor space can be air-conditioned by supplying air to the indoor space on the tile carpet 2 through the irregularly shaped chips of the backing layer 10.

  FIG. 10 shows another tile carpet 16 (second conventional tile carpet) different from the first conventional tile carpet 2 and a breathable support floor 18 on which the tile carpet 16 is placed. It is a partial expanded sectional view which shows a part. As shown in the figure, the breathable support floor 18 is also formed with a plurality of vent holes 20.

  The second conventional tile carpet 16 has a two-layer structure including a pile layer 24 made of pile fibers and a backing layer 22 that holds a plurality of portions of the pile fibers. . Plural portions of the pile fibers of the pile layer 24, that is, a plurality of loop-shaped bent connection portions of the pile fibers that are continuous with each other, are held on the surface layer portion of the backing layer 22.

  In such a tile carpet 16, a plurality of vent holes 26 having a round hole shape in a horizontal cross section, which penetrate and communicate with both the pile layer 24 and the backing layer 22, are arranged at substantially equal intervals in a horizontal plane. Is formed.

According to the tile carpet 16 and the breathable support floor 18 on which the tile carpet 16 is placed, the same combination as the first conventional tile carpet 2 and the breathable support floor 4 described above. In the room where these are laid, by installing an air duct (not shown) communicating with the space below the air-permeable support floor 18, the temperature and the like sent out from the air duct (not shown) are adjusted. The indoor space can be air-conditioned such that air is supplied to the indoor space on the tile carpet 16 through the vent hole 20 of the breathable support floor 18 and the vent hole 26 of the tile carpet 16. It was.

  However, in the first conventional tile carpet 2, air passes through the fine gaps between the chips adhering to each other in the backing layer 10, so that the air is passed through the tile carpet 2 in the thickness direction. Since the resistance at the time of passing is large, there is a problem that it takes time until the room temperature on the tile carpet 2 reaches the set temperature because the air flow rate per hour when air conditioning is performed is small (the flow rate is small).

  Further, in the conventional tile carpet 2, the gaps between the chips of the backing layer 10 are small and fine, so even small dust can be clogged or crushed when a heavy object is placed on it. There was a problem.

  Further, the second conventional tile carpet 16 also has a problem that clogging is likely to occur due to accumulation of dust in the vent hole 26 since the vent hole 26 has a round hole shape in the horizontal cross section.

  Further, in the second conventional tile carpet 16, since the plurality of vent holes 26 are formed by punching, the pile fibers of the pile layer 24 provided in the surface layer portion of the backing layer 22 are easily frayed. The diameter of the round hole 26 that can be punched is large enough to be clearly discerned with the naked eye. Therefore, there is a possibility that the hole 26 may become a dust reservoir and the appearance of the tile carpet 16. There was a problem of getting worse.

  Accordingly, in view of the above problems, the present invention is a tile carpet that can prevent the flow rate of air passing in the thickness direction from being reduced, dirt and clogging in the vent hole, and deterioration in appearance. It is a problem to provide.
