Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a tatami mat that is appropriately installed in a corner of the ocean.

[0002]

[Prior art]

 Conventionally, as a tatami mat that is laid in a room with this type of flooring, the back surface of the tatami mat has usually been given a non-slip treatment to prevent the tatami mat from being displaced. In order to prevent it, it is common to use adhesive tape or adhesive as the processing material without using fasteners. (See, for example, Japanese Utility Model Laid-Open No. 4-129248 and Japanese Patent No. 3005687).

As a method of forming the displacement prevention of the tatami without changing the structure of the tatami itself, a method of fixing a position by surrounding a plurality of tatami mats with a frame is also used. In this case, it is necessary to use a tool to assemble the tatami frame. (See, for example, Japanese Utility Model Publication No. 5-58743 and Japanese Utility Model Publication No. 5-87129).

[0004]

[Problems to be solved by the device]

 If the tatami mat is processed using adhesive tape or adhesive, the adhesive will elute from the end of the tatami mat's material to the surface or the material will peel off over time, and the exposed adhesive will cause the room to disappear. There is a risk of soiling the floorboards.

In the case of the method of fixing the position of the tatami with the tatami frame, it is appropriate that the tatami frame has a design structure that allows housewives to easily assemble, but it is actually troublesome to assemble with a tool.

Therefore, the present invention does not damage the floorboard even when a plurality of tatami mats are arranged in a corner of the ocean during use, and also displaces tatami mats by a tatami frame that can be easily installed and removed without using tools. The purpose is to provide a protected tatami mat.

[0007]

[Means for Solving the Problems]

 The present invention is a tatami mat in which a sheet-shaped synthetic fiber non-woven fabric is integrally sewn on the back surface of a tatami floor with an insulation board made of tatami mat, which is generally used for Japanese-style rooms, as the core. Consists of a tatami frame in which the outer circumference of a plurality of tatami mats placed in place is surrounded by a plurality of side frames with twist locks attached to the joints, and the side frames are connected by the twist locks. The above object has been achieved by providing a tatami mat characterized by the following.

Further, by forming a convex portion on one end of the side frame and a concave portion on the other end and aligning the convex portion of the side frame with the concave portion of another side frame, the twist lock is guided to a predetermined screwing position. This structure also achieves the above objective.

The non-woven fabric is preferably in the form of a single sheet having no breaks or joints.

Furthermore, it is preferable that all the edges of the non-woven fabric are sewn on the lateral surface of the tatami mat.

[0011]

[Action]

 The synthetic fiber non-woven fabric that forms the back of the tatami mat is a material that has a soft feel and is thin and strong, and can prevent damage to the floorboard by contacting the flooring floor.

Further, the side frames are arranged so as to surround the laid tatami mat, and the side frames can be joined or separated from each other by rotating the twist lock with bare hands without using a tool.

[0013]

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the tatami mat of the present invention comprises a plurality of tatami mats 1 and a plurality of side frames 2, and the tatami mat 1 further comprises a tatami body 4 and a nonwoven fabric 3 as shown in FIG. Composed of.

FIG. 2A is a perspective view of the back side of the tatami mat 1, and the tatami mat body part 4 is a tatami mat that has been processed into a state that can be generally used for a Japanese-style room. , Tatami edge. Since the tatami floor is the heaviest material among them, it is best to use a laminate of lightweight and highly rigid insulation board, polystyrene foam, etc. as the tatami floor when storing or relocating the tatami mat. It is suitable for pursuing the convenience of time.

The non-woven fabric 3 shown in FIG. 2 is made of synthetic fiber and is a material having a soft touch and a thin yet tough property, and has a protective function of preventing the floor plate from being damaged even when it comes into contact with the flooring floor. Have. For satisfying this function, for example, a product name “Cygnus sheet” manufactured by Azuchi Sangyo Co., Ltd. is suitable.

The non-woven fabric 3 has a size larger than the area of the back surface of the tatami body 4, that is, a size cut so as to slightly cover the four lateral surfaces of the tatami body 4, and the tatami body is cut at all cut ends. It is sewn to No. 4. The advantage of the sewing process is that the processed part does not easily tear even after years have passed.

However, since the nonwoven fabric 3 does not have an anti-slip effect, it is difficult to stay in a fixed position only by placing a plurality of tatami mats 1 and arranging them side by side. Therefore, a tatami frame formed of the side frames 2 is required.

The side frame 2 shown in FIG. 3 is processed into a predetermined length and height according to the shape of the tatami 1 and the number of sheets to be installed in the room. If you use a slope that is angled to the floor, you may fall when you step on it, so the outer lateral surface of the side frame 2 has an angle that is perpendicular to the floor. . A torsion lock main body 5a is attached to one end of the side frame 2, and the torsion lock main body 5a is prevented from falling off the side frame 2 by a torsion lock holder 5c shown in FIG. 4B. A twist lock receiving tool 5b is attached to the other end. The twist lock main body 5a and the twist lock receiving tool 5b are threaded so as to be coupled to each other. Further, a recessed surface 8 is provided on the back surface of the twist lock main body 5a, and a projection 7 is provided on the same surface as the twist lock receiver 5b at the other end.

When forming the tatami frame, the side frame 2 is arranged so as to surround the tatami 1 as shown in FIG. 1, and the concave portion 8 of the side frame 2 and the convex portion 7 of the other side frame 2 are simply brought into close contact with each other. As shown in FIG. 2, the positions of the hole 6 and the hole of the torsion lock receiving device 5b are aligned with each other, and the side walls 2 adjacent to each other are joined by turning the torsion lock body 5a clockwise with bare hands, or left side. It is separated by turning.

In FIG. 5, a plurality of tatami mats 1 are arranged on the floor, and four side frames 2 arranged on the outer periphery of the tatami mat are joined at four positions to form a rectangular tatami frame, which is a standing tatami mat. This is an example.

[0022]

[Effect of the invention]

 By using a non-woven fabric on the back side of the tatami mat, the flooring floor between the oceans will not be damaged, and the adhesive will not be used because it is sewn so that there is no worry of the floorboard getting dirty due to the adhesive squeezing out lost.

Further, since the assembly of the tatami frame by the twist lock does not use tools and does not require attachment of assembly parts, work safety and convenience are improved. This eliminates the need for installation work by a vendor and enables over-the-counter tatami mat sales and mail-order sales. The same applies to removal, and the tatami frame can be disassembled without the use of tools, and the tatami mat can be moved to another room, etc., if necessary.
