Description

  The present invention relates to a tatami fixed frame unit for fixing a tatami mat so that the tatami mat does not slip when a tatami mat or mat, particularly a judo tatami mat used for judo competitions, is installed in a gymnasium.

  When building a martial art such as judo or a sports competition, a game, or practice in a structure of a building that is not normally used as a gymnasium or an auditorium, lay a tatami mat on the floor to create a temporary Although it is a dojo, it is not possible to machine holes or grooves for mounting on the floor to rent a venue. In addition, after the game, the venue needs to clear the tatami mat and return it to its original state.

During judo competition, it is necessary to ensure that the tatami mats are securely attached to the floor of the venue and not slipped for safety and function. Conventional methods of fixing the judo tatami to the flat floor include a method in which a double-sided tape or adhesive sheet is applied between the tatami and the floor, and only the adhesive force is used. A suction cup is provided under the tatami to prevent the floor from being lifted. There are two methods: directly fixing the lower part of the tatami, such as things, and surrounding the outer side of the tatami mat with a solid fixed frame such as wood. For general tatami mats, a tatami frame unit has been devised as a plastic auxiliary outer frame.

  In the conventional method of using judo tatami mats, which uses a double-sided flat tape under the tatami mat, it is necessary to affix the tape under all the tatami mats to prevent the tatami mats from slipping completely. To add tatami mats, the work of inserting an auxiliary sheet was added, which was difficult. In addition, the adhesive strength weakened due to the adhesion of dust, and there was a problem with the fixing force for continuous use. The method using a suction cup was weak in its adsorption power and could not withstand the lateral displacement of the tatami mat for continuous use such as games. The method of surrounding the tatami floor with a solid fixed frame type such as wooden holds the tatami in the entire fixed frame and uses its own weight to fix the tatami mat, but requires a large amount of work to install. The tatami frame unit is a plastic auxiliary outer frame for general tatami mats that is not used for competitions, but it can be installed, but it cannot withstand strong skidding during competitions.

  The purpose of the present invention is to slidably fix the tatami mat on the floor surface by simple work on a flat floor surface that is difficult to drill and install in gymnasiums, etc., regardless of the venue size or installation shape. The judo tatami can be easily fixed even after the game has been held for a long time, and can be easily dismantled and removed without damaging the floor after installation and completion. Is to provide a means.

  Hereinafter, the implementation method of this invention is demonstrated based on FIGS.

  The present invention is a tatami mat frame for fixing a tatami mat for judo competition comprising a tatami fixing frame 1 and mounting sheets 2a and 2b and adhesive tapes 3a and 3b as shown in FIG. 1, and the mounting sheets 2a and 2b are fixed to the tatami mat. It is included in a state of being wrapped around the frame 1, and both ends of the attachment sheets 2a and 2b are directed toward the tatami installation side of the tatami fixing frame 1. Furthermore, the length of the sheet end on the tatami surface side is made longer than the length of the sheet end on the floor surface side of the attachment sheets 2a and 2b. Fix both ends of the mounting sheets 2a, 2b to the floor using adhesive tapes 3a, 3b.

  As shown in FIG. 2, the tatami fixing frame 1 has a structure in which one end has a convex shape 1a and the other end has a concave shape 1b, and constitutes a unit having a half space (about 90 cm) as one unit. The area of the tatami mat can be adjusted by adjusting the number of tatami mat frames to fit the size and shape of the venue.

  FIG. 3 shows the installation method of the tatami mat fixing frame 1, the mounting sheet 2 and the adhesive tapes 3a and 3b of the present invention. The mounting sheet for mounting the tatami fixing frame 1 is sandwiched between the floor surface and the lower surface of the tatami mat. It is installed at. The width of the mounting sheet should be approximately 25 cm to 35 cm. In FIG. 1, the attachment sheets are installed in two places such as the attachment sheets 2a and 2b for one tatami fixing frame 1, but three or more installation sheets may be installed. One end of the attachment sheet is first fixed to the flat floor 4 by the adhesive tape 3a, and after including the tatami fixing frame 1, the other end of the attachment sheet is extended at least 15 cm longer than the fixing position of the adhesive tape 3a. The adhesive tape 3b is fixed to the flat floor surface with the adhesive tape 3a covered by the mounting sheet.

  At the time of installation, the attachment sheet 3b at one end of the upper surface is made longer than the attachment part 3a at one end of the lower surface of the sheet as shown in FIG. The more the judo tatami is displaced by the lateral force due to the lateral friction of the upper and lower parts of the mounting sheet and the pressure from the top of the tatami, the more it forms a structure that tightens the fixed frame and the less the tatami skids slide Can be effective.

  The attachment sheet itself does not require adhesive strength, but it is preferable that the material has a high coefficient of friction, and it should be a strong material that does not stretch. Usually, about 1 place is installed in the vertical direction of the tatami mat and about 2 places in the horizontal direction.

  FIG. 4 shows an example of installation from the upper surface of the venue where the judo tatami 5 is fixed to the flat floor surface 4 using the tatami fixing frame 1 and the mounting sheet 2 of the present invention, and FIG. An example of installation is shown. As mentioned above, if the installation sheet is installed on the flat floor, it will not slip during the match.

  The tatami fixing frame and mounting sheet of the present invention are different from the method of fixing the tatami with the entire tatami fixing frame, and are the method of fixing the tatami with the installation surface of the floor mounting sheet and the fixing frame. Easy to process. For this reason, installation according to the shape of the venue becomes possible by adjusting the length of the tatami mat frame according to the deformed floor shape other than the rectangle.

  In conventional fixed frames, wooden frames and hard materials were used to firmly fix the tatami mats throughout the frame. However, a hard frame is dangerous when a player is thrown near the field, and when installing / disassembling, the wooden frame is often dropped on the floor and often damaged. On the other hand, the tatami fixing frame of the present invention is capable of shrinking rubber rubber or urethane material that is easy to absorb shocks and can be restored because the tatami is pinpointed only by the contact surface between the mounting sheet and the tatami. Since it is possible to use the material, it is not necessary to prevent the injury of the competitors and to worry about scratches during installation and dismantling.

  Because it is a method of fixing only with adhesive tape, it can be easily removed from the floor during dismantling work. Compared with the method of fixing the entire ground surface of the tatami mat with adhesive tape, only a part of the fixed frame in contact with the tatami on the outer periphery of the judo stadium is fastened with the adhesive tape. No trace of remains. This eliminates the need for worrying about repair costs at borrowed gymnasiums, etc., and can greatly reduce the time required for installation and dismantling, and it can be reused except for adhesive tape.

  The material of the tatami fixing frame, which is a component of the tatami mat frame of the present invention, is not particularly limited, and known materials (for example, wooden, metal, etc.) can be used, and the mounting sheet has a special anti-slip property. It does not have to be processed. However, the tatami fixing frame is made of hard rubber, foam resin, or other material that can easily absorb shocks, so it is safe for the user and protects the floor during installation.

  The tatami fixing frame touches the edge of the tatami so that it does not move by fixing the tatami, but its height may be slightly lower than the thickness of the tatami so as not to hinder the competitors during use. Preferably, the height from the floor is usually in the range of about 35 to 50 mm, the width is about 40 to 65 mm, and the heel of the foot is not burdened in consideration of the game at the tatami mat. The outer corner should be chamfered with a tapered structure.

By using the tatami fixing frame and mounting sheet of the present invention, holes and grooves can be processed in structures by laying tatami on the floor of buildings that are not normally used as dojos, such as gymnasiums and auditoriums. Since the stadium can be set up easily and unnecessary, it is possible to set up the competition at the borrowed facility.
In addition, in the conventional tatami fixing frame, it was often fixed so that it does not slip with a strong wooden or iron frame. However, in the present invention, the fixed frame is mainly supported by the point of the non-slip sheet surface and fixed. Because it is made of hard rubber or foam resin that absorbs shock and is easy to restore its shape, it not only improves the safety of the competitors, but also causes damage if dropped on the installation floor during installation. There is no.
