Description

[Technical field]

[0001] The present invention relates to a frame member that is placed on the outer periphery of a tatami mat. [Background technology]

[0002] In recent years, while the number of rooms with wooden floors has increased, there is also a demand for tatami mats. As a result, a trend has emerged where two or three tatami mats of thin tatami mats are laid between the flooring to create a partial tatami room. However, simply placing the tatami mats will cause them to separate and fall apart, so they need to be fixed together. For this reason, methods such as interlocking the individual tatami mats or fixing all the tatami mats together with a frame, as disclosed in Patent Document 1, are used. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2006-307509 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, even these fixing methods have the following drawbacks. That is, fixing tatami mats individually requires special processing of the tatami mats, which can damage them. On the other hand, the frame material method described in Patent Document 1 solves these problems, but it has problems such as (i) the need for connectors between the frame materials, (ii) when the straight frame portion and the corner frame portion are separate bodies that constitute the frame member, it is necessary to prepare each separately, (iii) when the straight frame portion and the corner frame portion are integrated into the frame member, it is difficult to change the size of the frame member, and (iv) (i)-(iii) result in increased costs for both users and manufacturers.

[0005] The present invention has been made to solve the problems described above, and aims to provide a frame member for floor-standing tatami mats that is versatile for the square shapes formed by floor-standing tatami mats and allows for cost reduction for both users and manufacturers. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention is configured as follows. In other words, the frame member for placed tatami mats in the first aspect of the present invention is a frame member for placed tatami mats that is placed closely together in a square shape on the floor surface and is fitted over the outer edge of the placed tatami mat to fix the placed tatami mat, and is characterized by having a straight member extending along one side of the placed tatami mat and a corner member that is arranged to correspond to the corner of the placed tatami mat, the corner member being molded integrally with the straight member at one end in the longitudinal direction of the straight member, and a cutting portion that is provided at the boundary between the straight member and the corner member and allows the straight member and corner member to be cut and separated. Effect of the Invention

[0007] According to the first aspect of the present invention, the straight members and the corner members are molded integrally to form one type of frame member, but the corner members can be separated from the straight members by having a cut portion. Therefore, two types of frame members can be formed from one type of frame member: a frame member having straight members and corner members, and a frame member having only straight members. This makes it possible to combine these, and excellent versatility can be obtained for size variations of tatami mats. As a result, the manufacturer only needs to make one type of mold to mold one type of frame member, which reduces costs and makes it possible to reduce product prices. In addition, users only need to purchase one type of frame member for the above-mentioned size variations, which eliminates the trouble of purchasing multiple types of frame members and the risk of purchasing the wrong one, and also reduces purchase costs by reducing product prices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The embodiment of the present invention, a frame member for tatami mats, will be described below with reference to the drawings. In each drawing, the same or similar components are given the same reference numerals. In order to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art, detailed descriptions of already well-known matters and duplicate descriptions of substantially identical components may be omitted. In addition, the contents of the following description and the accompanying drawings are not intended to limit the subject matter described in the claims. In addition, each drawing is an image-based conceptual diagram to assist in the description, and does not accurately depict the actual form.

[0010] As shown in Fig. 5(a) and (b), the frame member 100 in this embodiment is a frame member for tatami mats that is attached to the entire outer periphery of multiple tatami mats 10 placed on the floor surface 20 in a closely spaced, for example rectangular shape, to prevent the multiple tatami mats 10 from coming apart (connecting the multiple tatami mats 10) and to prevent all the tatami mats 10 from sliding on the floor surface 20 and to fix them in place. For ease of explanation, an arrangement of multiple tatami mats 10 will be referred to as a "tatami mat assembly" below. Also, in this embodiment, an example is taken of the case where the frame member 100 is placed on such a tatami mat assembly, but it is also possible to apply the frame member 100 to a single tatami mat 10. Even in the case of a single tatami mat 10, the frame member 100 prevents it from sliding on the floor surface 20 and fixes it in place. As described later, the frame member 100 has a slope, and therefore also serves to reduce the difference in level between the floor surface 20 and the tatami mat 10.

[0011] Here, the tatami mat 10 does not mean a tatami mat that is laid out over the entire surface of a room, but rather a tatami mat that is placed like a rug in a part of a room, and is generally movable. For this reason, it is usually constructed to be thin (about 10 to 25 mm) so as not to cause tripping. Also, it does not have to be a special tatami mat, and it can be any type of tatami mat, such as not only a normal tatami mat, but also a reversible tatami mat whose reverse side is a different rug (carpet or other), or a tatami mat with tatami mat surface on both sides but with different weaves. Also, it can be a tatami mat with or without a border. Tatami facings can be made from woven natural rush or imitation rush. Imitation rush is made from plastic or paper and shaped to roughly the same thickness as natural rush. Any manufacturing or shaping method is acceptable. Also, the weaving method is free and does not have to be special. The size of one tatami mat 10 may be a half tatami mat type, a one tatami mat type, or a non-standard size. It is usually rectangular, but it may be triangular or another shape.

[0012] 1A-1E, the frame member 100 includes a straight member 110, a corner member 120, and a cutting portion 130, which are integrated into a single product. The cutting portion 130 is located at the boundary between the straight member 110 and the corner member 120, and corresponds to the portion connecting the two. Such a frame member 100 can be produced by integrally forming the straight members 110, the corner members 120, and the cut portions 130 using injection molding of a resin material. The frame member 100 may also further include an insert member 140, which in this embodiment is molded together with the straight member 110.

[0013] In addition, the frame member 100 has approximately the same height as the tatami mat 10 (height H from the floor surface 20) as shown in Figures 1B and 1E so that the tatami mat 10 does not protrude from the floor surface 20, and the cross-sectional shape of the frame member 100 is preferably a triangular or tapered shape that is difficult to trip over, as shown in Figures 1B and 1E. In this embodiment, a slope 114 is formed as shown in Figures 1B and 1E. Furthermore, anti-slip rubber or the like may be provided on the back surface of the frame member 100 that contacts the floor surface 20. Each of these parts will be explained in more detail below.

[0014] In this embodiment, one tatami mat 10 has a square planar shape. Therefore, in this embodiment, the straight member 110 is a member having a length L that extends along one side of one tatami mat 10 as shown in FIG. 1A. An example of the length L is about 830 mm. The straight member 110 has an engaging portion 152 that protrudes from one end surface 111 in the longitudinal direction 182 along the length L of the straight member 110. The engaging portion 152 is a portion that can engage (connect) with an engaged portion 154, which will be described later, and is molded integrally with the straight member 110.

[0015] The other end surface 112 of the straight member 110 in the longitudinal direction 182 corresponds to the cut portion 130, and the corner member 120 is molded integrally with the straight member 110 on the other end surface 112. The corner member 120 is a member that is placed in correspondence with the corner 11 (FIG. 5(a)) of the floor tatami mat 10, and in this embodiment, it has an end surface 121 that is deflected 90 degrees from the other end surface 112 of the straight member 110 on the floor surface 20. Therefore, in this embodiment, the side surface 113 of the straight member 110 that contacts the floor tatami mat 10 and the end surface 121 of the corner member 120 are positioned in a straight line.

[0016] Also, as shown in FIG. 1A, slopes 114 in straight members 110 and corner members 120 are provided with anti-slip protrusions 115 that also serve an aesthetic effect, but the presence or absence of such protrusions and their shape are not intended to be limited to those shown in the figure.

[0017] 1D, the corner member 120 has an engaged portion 154 on its end face 121 that can engage with the engaging portion 152. Therefore, the engaging portion 152 formed on one end face 111 of the straight member 110 in one frame member 100 and the engaged portion 154 formed on the end face 121 of the corner member 120 in another frame member 100 can be engaged with each other as shown in FIG.

[0018] It should be noted that the angle of deflection of the corner member 120 is not limited to 90 degrees as in this embodiment, but may also have a deflection angle of 45 degrees. In addition, in this embodiment, the engaging portion 152 and the engaged portion 154 are rectangular convex and concave portions as shown in the figure, but the shape of the engaging portion 152 and the engaged portion 154 is not limited to a rectangular shape, and can take any shape that can be used by an engaging means composed of concave and convex shapes, such as a circle, a polygon, a groove, etc.

[0019] The cutting portion 130 is a portion having a configuration that facilitates cutting and separating the straight member 110 and the angular member 120, which are molded integrally together. Specifically, for example, in order to enable a user of the frame member 100 to cut both of them with a cutting tool such as a cutter, the cutting portion 130 is a portion having a configuration that includes a mark or line, a cutout, a so-called perforation, a thinner wall than other portions, etc. In addition, in the case of perforation, cutting is possible without using a cutting tool.

[0020] Moreover, when the angular member 120 is separated by the cut portion 130, the straight member 110 has another end surface 112 corresponding to the cut portion 130 so that an end surface is generated in the straight member 110. The other end surface 112 has an engaged portion 154 formed thereon so as to be engageable with an engaging portion 152 in another straight member 110, as shown in Figs. 1D and 1E.

[0021] Next, in this embodiment, the insertion member 140 is integrally molded with the straight member 110, and has a form in which the bottom surface of the straight member 110 is extended from the side surface 113 of the straight member 110 in a protruding direction 184, and extends along a longitudinal direction 182, as shown in Figures 1B, 1D, and 1E. The thickness of the insertion member 140 is, for example, about 1 mm to about 3 mm. The protruding direction 184 is perpendicular to the longitudinal direction 182.

[0022] As shown in FIG. 1B, this type of insertion member 140 is a part that slides across the floor surface 20 and is inserted between the floor surface 20 and the back surface of the tatami mat 10 placed on the floor surface 20, and is a part that exerts effects such as limiting the movement of the frame member 100 relative to the tatami mat 10 and making installation easy.

[0023] Further, the tip of the insertion member 140 in the protruding direction 184 has an inclined surface 142 to facilitate insertion of the insertion member 140 into the back surface of the tatami mat 10. Furthermore, chamfered sections 144 are provided on both ends of the insertion member 140 in the longitudinal direction 182, which prevents interference between the insertion members 140 in each frame member 100 when connecting the corner members 120 and the straight members 110. Also, by providing the chamfered sections 144, it is possible to facilitate the insertion of the insertion member 140 into the tatami mat 10 and prevent interference with the user, and it is also possible to prevent the insertion member 140 from damaging the floor surface 20 or the tatami mat 10 when installing the frame member 100.

[0024] The inclined surface 142 can also achieve the following effects. That is, it can prevent the tatami mat 10 from lifting up or the occurrence of a step when the frame member 100 is installed on the tatami mat 10. Also, by increasing the length of the inclined surface 142 in the protruding direction 184 (reducing the thickness of the inclined surface 142), it is possible to make it easier for the insertion member 140 to conform to the unevenness of the floor surface 20. It is also possible to prevent the inclined surface 142 itself from lifting up or warping due to the weight of the tatami mat 10 itself.

[0025] In this embodiment, as described above, the cut portion 130 is provided at one position on the frame member 100 in the longitudinal direction 182, but as a modified example, as shown in FIG. 3, it may be provided at multiple positions. That is, in order to accommodate size variations of the tatami mat 10 or more flexible size changes of the frame member 100, multiple cut portions 130 can be formed in advance in the longitudinal direction 182. Note that FIG. 3 shows a case where three more cut portions 130 (total of four) are provided. Each cut portion 130 is configured to form the other end surface 112 of the straight member 110 and further to form an engaged portion 154. Here, when multiple cut portions 130 are provided, the length of the insertion member 140 is set to match the cut portion 130 at which the straight member 110 is the shortest, as shown in the longitudinal direction 182.

[0026] In this way, by forming a plurality of cut portions 130, it becomes possible to change the length of the straight member 110, and therefore the versatility of the frame member 100 can be further increased.

[0027] The use, functions, etc. of the frame member 100 having the above-mentioned configuration will be described below. For ease of explanation, the frame member 100 in which the corner members 120 have been removed using the cutting portion 130, leaving only the straight members 110, will be referred to as "frame member 101" (FIGS. 2A-2C). In this embodiment, as shown in FIG. 5(a), a tatami mat assembly 50 in which four square tatami mats 10 are arranged in a square shape on the floor surface 20 is taken as an example.

[0028] As described above, in this embodiment, the length of one side of one tatami mat 10 corresponds to the length L of the straight member 110 of the frame member 100, so in order to install frame members on the entire outer periphery of the tatami mat assembly 50 in this example, eight frame members 100 of the same type are prepared.

[0029] Next, for four of the eight frame members 100 described above, the corner members 120 are cut off using the cutting section 130 to generate four frame members 101 each having only the straight members 110. That is, four frame members 100 and four frame members 101 are prepared.

[0030] Next, as shown in (a) of Figure 5, frame members 100 and 101 are alternately arranged along the outer peripheral edge of folding assembly 50, for example in a clockwise direction from the upper left, in the order of frame member 100, frame member 101, frame member 100, and the engaging portion 152 and the engaged portion 154 are engaged with each other.

[0031] As described above, frame members 100 and 101 can be installed along the entire outer periphery of tatami mat assembly 50. As a result, tatami mat assembly 50 can be fixed to floor surface 20.

[0032] Thus, according to this embodiment, two types of frame members can be formed from one type of frame member: frame member 100 having straight members 110 and corner members 120, and frame member 101 having only straight members 110. Therefore, frame member 100 of this embodiment can be combined with frame member 101, and excellent versatility can be obtained for size variations of a square-shaped tatami mat assembly formed from multiple tatami mats. As a result, the user simply needs to purchase one type of frame member 100, eliminating the need to go to the trouble of purchasing multiple types of frame members, and also eliminating the need to make mistakes when purchasing them. Furthermore, the user also has the advantage of not having to consider how to combine them. On the other hand, for the manufacturer, it is only necessary to produce a mold for one type of frame member 100, which has the advantage of reducing manufacturing costs and ultimately reducing product prices.

[0033] On the other hand, even when the frame member 100 is applied to one floor tatami mat 10, the frame member 100 can achieve the above-mentioned effects. That is, four frame members 100 are usually used for one floor tatami mat 10. Here, for example, cases are assumed in which the size of the floor tatami mat 10 itself is changed, or the floor tatami mat 10 is applied to a rectangular floor tatami mat 10 instead of a square one. Even in such cases, as described above, it is possible to create two types of frame members by using the cut parts 130 and form a combination of them. Furthermore, in a form having multiple cut parts 130, the length of the straight member 110 can also be changed, so the frame member 100 of this embodiment can achieve effects such as high versatility even when applied to one floor tatami mat 10.
