Description

  The present invention relates to a base installed on a floor for use in competitions such as wrestling performed in a room such as a gymnasium.

  Conventionally, as a tatami for judo, in the following Patent Document 1, a tatami floor is formed by sequentially laminating a polypropylene corrugated sheet and a polyethylene foam on top and bottom of a polystyrene foam, and this tatami floor is covered with a tatami surface. What was formed is described. Such tatami mats are laid directly on the floor of a gymnasium or the like.

  On the other hand, in competitions such as high school generals and national sports, a wrestling competition venue that is held indoors in a gymnasium or the like is provided with a base of about 60 cm in height on the floor, with a mat placed on it. Placed.

  As this base, a structure in which a large number of block-like polystyrene foams are arranged or a structure in which iron pipes are assembled is usually used.

Japanese Utility Model Publication No. 7-5667

  However, as described above, in the base where a large number of polystyrene foams are arranged, polystyrene foam is very bulky. Therefore, it takes a lot of labor and cost to transport the foams. Space is required and storage costs are also an issue.

  In addition, iron pipe structures require workers with special skills to assemble and cannot be dealt with only by officials and volunteers at the tournament, and they are also poorly buffered when used in competitions. There's a problem.

  Therefore, an object of the present invention is to provide a base for indoor sports competition that can efficiently store and transport materials, can be easily assembled by anyone, and has excellent buffering properties.

  In order to solve the above-described problems, a base for indoor sports competition according to the present invention is provided with kerfs in a large number of cardboard partition plates, and these partition plates are meshed with the kerfs in the form of a cross-beam. A top plate having a multi-layered structure was placed on the receiving body by placing a number of cardboard boards, a wooden board and a cardboard board so as to overlap each other.

  Since this indoor sports competition base is composed of subdivided plate-like members, it is not bulky when stored and transported in a dismantled state, and is made of cardboard and It can be easily assembled even for those who do not have special skills, simply by placing a top board with wooden floors.

  In addition, the cardboard used as the partition plate of the cradle and the base plate of the top plate serves as a cushion to reduce the impact during the competition, and the bending strength of the top plate is also secured by the wooden base plate, such as the opening ceremony It can withstand even if a large number of people are on the event and a large load is applied.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 5, the indoor sports competition base is installed on the floor of the venue for wrestling competition performed indoors in a gymnasium or the like.

  In order to assemble this foundation, first, as shown in FIG. 1, a plurality of cardboard partition plates 1 and 2 are provided with kerfs 3 on the upper side or lower side thereof, and these partition plates 1 and 2 are cut into kerfs 3. The support body 4 is formed by meshing in a cross-beam shape so as to be orthogonal to each other.

  The partition plate 1 is approximately twice as wide as the partition plate 2, and the partition plate 1 has two kerfs 3 and the partition plate 2 has one kerf 3. When forming the support body 4, two partition plates 1 are shifted in a staggered manner and stacked, and the partition plates 2 are stacked on the partition plates 1 at the end of each row.

  AB double-sided cardboard is used as the material for the partition plates 1 and 2, and the step is directed vertically.

  Next, as shown in FIGS. 2 and 3, a large number of cardboard floorboards 5, wooden floorboards 6 and cardboard floorboards 7 are spread on the support body 4 so as to overlap each other in order to obtain a three-layer structure. The top plate 8 is placed.

  The floor plate 5 as a lower layer is made of AB double-sided cardboard, and is a square having a size straddling several vertical and horizontal partition plates 1 and 2 of the support 4.

  The floorboard 6 as the middle layer is a wooden plywood and has a rectangular shape smaller than the floorboard 5 because the weight per unit area is larger than the cardboard.

  The laying board 7 as an upper layer is made of AAA double-sided cardboard and has the same size and shape as the laying board 5.

  Then, as shown in FIG. 4, the floor boards 7 are fixed to each other with the adhesive tape T, and the adhesive tape T is wound around the floor boards 6 and 5 at the peripheral edge of the top board 8.

  The support body 4 and the top plate 8 need not be fixed in particular because the partition plates 1 and 2 bite into the floor plate 5 due to the load acting on the top plate 8 to prevent horizontal displacement. .

  After that, as shown in FIG. 5, when a curtain 9 is stretched around the support body 4 and a carpet 10 is laid on the top plate 8 to create and fix the mat 11, a wrestling base is completed.

  Since the base as described above is composed of the partition plates 1 and 2 and the floor plates 5, 6, and 7 which are subdivided plate-like members, it is easily transported easily and efficiently without being bulky in a disassembled state. And does not require vast space for storage.

  In addition, it is easy to assemble even for those who do not have special skills by simply placing the top plate 8 on which the floor plates 5, 6 and 7 are laminated on the support body 4 which is engaged with the partition plates 1 and 2. Can do.

  Moreover, the cardboard used as the partition plates 1 and 2 of the support body 4 and the base plates 5 and 7 of the top plate 8 serves as a cushion, so that the shock during the game is alleviated. The bending strength is also ensured, and even when a large number of people are placed on the top board 8 and a large load is applied during an event such as an opening ceremony or cheerleading, it can withstand.

  Furthermore, by the reverse procedure of the above assembly process, it is possible to dismantle and withdraw after the tournament, simply and quickly.
