[Industrial applications]

 The present invention relates to a tatami mat which has a cushioning property between a portion under the wall and the tatami mat.

[0002]

[Prior Art]

 In industrialized production houses, tatami mats are provided at the boundary between the tatami mat under the wall. FIG. 3 is a sectional view showing a boundary between a tatami mat and a wall under which a conventional tatami mat is provided.

A tatami mat 3 in the shape of a horizontal tree is provided under the wall 1 between the pillars, and the end surface of the tatami mat 5 is in contact with the tatami mat 3. When the tatami mat 3 is in contact with the tatami mat 5, the upper surfaces of the tatami mat 3 and the tatami mat 5 are flush with each other. By the way, a gap may occur between the end surface of the laid tatami mat 5 and the tatami mat 3 due to a dimensional error of the wall panel and the tatami mat 5. For this reason, the thickness of the tatami mat 3 is determined by actually measuring the gap in each room. A sponge 7, which is an elastic material, is attached to the end surface of the tatami mat 5 that is in contact with the tatami mat 3. The sponge 7 is shrinkably inserted in the gap so as to absorb a dimensional error generated between the end surface of the tatami mat 5 and the tatami mat 3. In the case of a quadrangular tatami laying surface, this sponge 7 is an end surface of the tatami 5 that is in contact with two adjacent tatami mats 3 (tatami mats attached to two sides sandwiching any corner of the tatami mating surface). It is attached to the tatami mat and can absorb the dimensional error in the two orthogonal directions on the tatami mat laying surface, and eliminate the gap between tatami mat 3 and tatami 5 caused by the dimensional error.

[Problems to be solved by the device]

 A tatami mat 3 in the form of a horizontal tree is provided under the wall 1 between the pillars, and the thickness of the tatami mat 3 is determined by actually measuring the gap between the under the wall 1 and the tatami mat 5. Further, a sponge 7 is attached to the end surface of the tatami mat 5 which is brought into contact with the tatami mat 3 so as to absorb a dimensional error between the tatami mat 3 and the end surface of the tatami mat 5. However, when laying the tatami mat 5, it is not easy to measure the gap each time, and the dimensional error cannot be sufficiently absorbed by adjusting the gap size only with the sponge 7, which is an obstacle to the industrialization of the tatami mat 5. Was there.

The present invention has been made in view of the above circumstances, and pays attention to the tatami side where the tatami end face abuts, and can sufficiently absorb the change in the gap size caused by the wall panel and tatami size error. The purpose is to eliminate on-site work and eliminate obstacles to the industrial production of tatami mats.

[0006]

[Means for Solving the Problems]

 The structure of the tatami mat according to the present invention for achieving the above object is a tatami mat that has only a lower part sandwiched between the under wall and the tatami mat, and the upper part other than the lower part is made of a rigid member, and the lower part Is made of a soft member having a cushioning property.

[0007]

[Action]

 The upper part of the tatami mat is exposed and attached to the corner between the under wall and the tatami mat, and the under wall is protected and the street at the corner is exposed. The lower part of the tatami mat is compressed according to the gap between the under wall and tatami mat, and changes in the gap size caused by the dimensional error between the wall panel and tatami mat are absorbed.

【Example】

 Hereinafter, a preferred embodiment of a tatami mat according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sectional view showing a structure of a tatami mat according to the present invention, and FIG. 2 is a sectional view showing a boundary portion between a tatami mat under a wall and a tatami mat according to the present invention.

The tatami mat 11 according to the present invention has an outer shape of a skirting board and a rectangular cross-section in a direction orthogonal to the longitudinal direction. The tatami mat 11 is arranged with its long side in the vertical direction in the vertical direction, and the upper part 13 is a hard member 15 which is a hard member, and the lower part 17 is a soft member 19 which is a soft member from a substantially central portion. That is, the tatami mat 11 is formed by vertically joining the cross-shaped upper part 13 and the lower part 17 in the vertical direction. Therefore, when the skirting board-shaped tatami mat 11 is attached under the wall, the upper part is hard and the lower part is soft. Examples of the material of the hard member 15 include wood used for ordinary skirting boards, synthetic resin material, and the like, and the material of the soft member 19 includes sponge having a cushioning property.

At the joint between the hard member 15 and the soft member 19 on the surface of the tatami mat 11 (the surface opposite to the surface attached to the lower surface of the wall), the corners of the hard member 15 and the soft member 19 are respectively formed. It is chamfered (curved chamfer in this embodiment). That is, the corners to be joined are chamfered, so that the joined portion of the tatami mat 11 is in a recessed state from the surface (see a portion in FIG. 1). The surface of the tatami mat 11 is covered with a wood-patterned wrapping material 21 over the upper part 13 and the lower part 17. Therefore, by covering the wrapping material 21, the recess at the joint is covered with a hollow shape, and no recess is formed on the surface of the mat 11.

As shown in FIG. 2, the tatami mat 11 having the above-described structure has a portion corresponding to the soft member 19 sandwiched between the lower wall 1 and the tatami mat 5, that is, substantially below the center. It is attached to the lower wall 1 in the state where it is attached. The upper half of the tatami mat 11 which is the hard member 15 is attached to the corners of the lower wall 1 and the tatami mat 5 so as to be exposed in the shape of a skirting board so that the lower wall 1 is protected and the passage at the corners is easy to come out. Become. When the tatami mat 5 is laid on the tatami mat laying surface, a dimensional error occurs between the lower wall 1 and the end surface of the tatami mat 5 due to the dimensional errors of the wall panel and the tatami mat 5. The size of the gap between the under-wall 1 and the tatami 5 changes due to a dimensional error, but the soft member 19 is appropriately compressed according to the changed gap size, and the soft member 19 is generated between the under-the-wall 1 and tatami 5. Dimensional error is absorbed. When the soft member 19 is compressed, the thickness of the soft member 19 becomes thinner than that of the hard member 15, and the corner of the hard member 15 at the joint (the boundary between the hard member 15 and the soft member 19) becomes the lower edge. Since the chamfered corner becomes the lower edge, no angular step is formed at the joint of the tatami mat 11.

[0013]

As described above in detail, according to the tatami mat according to the present invention, the lower part sandwiched between the lower part of the wall and the tatami is a soft member having cushioning property, and the upper part is a hard member. As a result, the exposed upper part can protect the lower part of the wall, as well as the passage at the corner, and the sandwiched lower part depends on the size of the gap between the wall panel and tatami mat. Since it is compressed, the gap size error can be sufficiently absorbed. Further, the lower part having a different thickness due to a dimensional error is not exposed by the upper part, and only the upper part having a constant thickness is always exposed, so that it is possible to prevent deterioration of appearance. As a result, it is not necessary to perform on-site work for each gap size, and it is possible to eliminate obstacles to the industrial production of tatami mats.
