Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tatami frame that forms a tatami-mat floor that can be moved to a corner of an ordinary home or a classroom such as a school or kindergarten.

[0002]

[Prior art]

 In the past, when laying multiple tatami mats on a Western-style house of a general household, large-scale construction was required to peel off the western-style board and secure the depth necessary to lay the tatami mat.

[0003] Although there are tatami frames that surround the outer periphery of tatami mats laid on the floor surface to temporarily form a tatami mat floor, in many of them, adjacent frames are hammered together with nails or the like to join the frames. Was. Furthermore, the frame itself was also struck with nails or the like and fixed to the floor surface.

[0004]

[Problems to be solved by the device]

 However, if you want to temporarily create a tatami space in a corner of the room, it would be a burden to the user if you had to reconstruct the Western-style room into a Japanese-style room. In addition, even though the Western-style room has been remodeled into a Japanese-style room, it may be necessary to re-use it as a Western-style room due to various reasons. At this time, the Japanese-style room must be rebuilt into a Western-style room, which is economically inefficient. .

On the other hand, when using a tatami frame in which adjacent frames are driven by nails or the like, a skill required for assembling the frames is required, and in so-called amateur work, there are problems such as poor appearance in appearance. . In addition, some of the nails that connect the frames to each other remained protruding outside the frame, and the nails were stuck in the feet of people walking in the room, which was extremely dangerous. Moreover, since the frame itself is fixed to the floor, the position of the tatami mat laid on the floor could not be freely moved. In addition, the tip of the nail protruded to the floor side, causing a large scratch between the boards. In addition, when disassembling the frame, it was necessary to pull out the nails that had been driven in one by one, and it took time to remove the frame.

In view of the above, according to the present invention, a plurality of frames can be easily joined and a tatami mat can be placed in the frame so that the tatami mat can be moved to a room of a general household or a corner of a classroom such as a school or kindergarten. It was devised as an issue to provide a tatami frame that forms the floor.

[0007]

[Means for Solving the Problems]

 Therefore, the present invention is a tatami frame that includes a plurality of side frames and surrounds the outer periphery of a tatami mat that is laid at a predetermined position. The side frame has a convex portion at one end and a concave portion at the other end. The above-mentioned problem is solved by providing the above-described structure and forming the convex portion of the side frame into the concave portion of the other side frame to join the side frames.

In addition, the convex portion of the side frame has a substantially trapezoidal end surface that is inversely tapered in the longitudinal direction, and the concave portion of the side frame includes a square-shaped entry concave portion for inserting the convex portion of the side frame and a convex portion. The above-mentioned problem is also solved by being configured with a fitting concave portion that moves in the horizontal direction and is fitted onto the convex portion.

[0009]

[Action]

 Therefore, in the present invention, the convex portion of the side frame is fitted into the concave portion of the other side frame to form a tatami frame, and a plurality of tatami mats are put in this frame to form a tatami floor.

Specifically, the convex portions of the end frame substantially trapezoidal columnar side frames, which are inversely tapered in the longitudinal direction, are fitted into the fitting concave portions of the other side frames to join adjacent side frame members together. It is what you do.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the tatami frame of the present invention, as shown in FIG. 1, by inserting the convex portion 1 of the side frame A into the concave portion 2 of the other side frame B, the adjacent side frames A and B are joined together. By creating a frame of a predetermined shape and laying a tatami mat C inside this frame, a tatami mat floor is temporarily formed in the western space.

The side frames A and B may be configured by, for example, preparing four side frames each having a convex portion 1 at one end and a concave portion 2 at the other end, or a convex portion at both ends. The frame may be composed of two side frames provided with 1 and two side frames provided with recesses 2 at both ends. Further, a frame is constructed by using a plurality of (four or more) side frames A and B according to the size and shape of the tatami floor.

As shown in FIGS. 2 (I) and 2 (II), the convex portion 1 of the side frame A has a substantially trapezoidal end face, and is formed in a reverse taper shape in which the lateral width is widened from the base end to the tip.

As shown in FIGS. 3 (I) and (II), the concave portion 2 of the side frame B is made to enter the rectangular concave portion 3 into which the entire convex portion 1 of the side frame A is inserted from the tip end side. Consists of a fitting recessed portion 4 which moves the convex portion 1 of the side frame A horizontally and externally fits on the convex portion 1.

The entry concave portion 3 may have any shape as long as the entire convex portion 1 of the side frame A can be inserted into the concave portion 2 of the side frame B. As shown in FIG. 3 (II), the fitting concave portion 4 has a substantially trapezoidal columnar end face, and the fitting concave portion 4 is formed to fit into the convex portion 1 which is formed in a reverse taper shape in which the lateral width is widened from the base end to the tip. 4 is formed so that the lateral width on the outer side is narrower than the lateral width on the inner side of the fitting recess 4.

The use of the present invention is described below.

First, a plurality of side frames A and B having a predetermined length are prepared according to the shape and size of the tatami mat floor to be created. Then, the convex portion 1 of the side frame A is fitted into the concave portion 2 of the other side frame B and the adjacent side frames A and B are joined together. Specifically, the entire convex portion 1 of the side frame A is put into the entry concave portion 3 of the side frame B, and the convex portion 1 of the side frame A is horizontally moved so that the convex portion 1 is fitted into the concave portion of the side frame B. 4 is fitted on the outside.

At this time, the convex portion 1 of the side frame A has a substantially trapezoidal end face and is formed in an inverse taper shape in which the lateral width is widened from the base end to the tip, and the fitting concave portion 4 of the side frame B is fitted into the fitting concave portion 4. Since the outer lateral width is formed to be narrower than the inner lateral width of the fitting concave portion 4, the convex portion 1 of the side frame A in the fitted state comes out of the fitting concave portion 4 of the side frame B. Never.

Then, as shown in FIG. 4, side frames A and B are connected to each other at four places to form a square tatami frame, and a plurality of tatami mats C are put in the frame to provide a tatami floor. To form.

When the use of the tatami frame is stopped, the laid tatami mat C is removed and the convex portion 1 of the side frame A fitted in the fitting concave portion 4 is inserted into the side frame B on the entry concave portion 3 side. Then, by removing the convex portion 1 of the side frame A from the position of the entry concave portion 3, the joined state of the adjacent side frames A and B is released.

[0022]

[Effect of device]

 The present invention configured as described above is a tatami frame which is composed of a plurality of side frames A and B and surrounds the outer periphery of a tatami C which is laid in plural at predetermined positions. The side frames A and B are Since the convex portion 1 is provided at one end and the concave portion 2 is provided at the other end, the convex portion 1 of the side frame A is fitted into the concave portion 2 of the other side frame B to join the side frames A and B, Anyone can easily make a tatami frame and temporarily form a tatami-mat floor in the open space of a general home or in a corner of a classroom such as a school or kindergarten.

Specifically, the tatami frame can be completed in an extremely short time because it is a simple work to fit the convex portion 1 of the side frame A into the concave portion 2 of the other side frame B. Also, by adjusting the lengths of the side frames A and B, it is possible to easily complete a tatami mat C of any size and a tatami frame surrounding a plurality of tatami mats C arranged in various shapes. In particular, when a half-mat tatami mat is used as the tatami mat C, an interesting pattern can be constructed by devising the arrangement of the tatami mat C itself.

Further, since the nail is not used for joining the side frames A and B, there is no possibility that the nail will be stuck on the floor surface and scratched. Moreover, since the side frames A and B are not fixed to the floor surface, the tatami floor can be freely moved as needed.

On the other hand, the convex portion 1 of the side frame A has an end face substantially trapezoidal column shape which is inversely tapered in the longitudinal direction, and the concave portion 2 of the side frame B has a rectangular shape in which the convex portion 1 of the side frame A is inserted. Since the convex portion 1 of the side frame A in the fitted state is formed by the concave portion 3 and the fitting concave portion 4 which moves the convex portion 1 in the horizontal direction to be fitted onto the convex portion 1, the fitting concave portion of the side frame B is fitted. It does not come off from 4, and it can be constructed robustly with a tatami frame. Further, the tatami frame can be easily disassembled, and the side frames A and B can be stored extremely compactly.

In addition, the present invention is advantageous in practical use such that the unit price of the product can be reduced because the side frames A and B can be easily produced and is suitable for mass production.
