[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stadium facility that can easily and quickly lay another competition surface on a floor surface, for example, in a gymnasium.
[0002]
[Prior art]
For example, in a gymnasium, when changing from a kendo stadium to a judo stadium where competitions are performed on tatami mats, or vice versa, in the past, many workers carried tatami one by one, It took a lot of time and manpower to make changes.
[0003]
Therefore, in order to change from a certain stadium to a stadium having different floor functions and performances, there has been proposed a foldable movable floor equipment that can be folded and moved. This foldable movable floor surface equipment lays another floor surface having other functions for competition on the floor surface of a certain stadium, and is configured as follows.
[0004]
In other words, the folding movable floor surface equipment divides the floor surface to be another stadium into an even number (hereinafter, the divided floor surface is referred to as a floor piece), and two of the divided even floor pieces are paired. As shown in the figure, the back surfaces of the floor pieces are opposed to each other in a letter C shape, and a pivot member is provided on the upper part of the rear surface of each floor piece opposed to the letter C shape, and a link is pivotally supported between these pivot members. On the other hand, a wheel that moves in the direction of expansion / contraction of the angle of the C-shaped top is provided at the lower part of each floor piece opposed to the C-shape, The angle between the lower part of one floor piece opposed to the shape and the lower part of the other floor piece opposed to the adjacent C-shape can be expanded and contracted, and a connecting member for connecting them is provided. .
[0005]
The foldable movable floor equipment having the above-described configuration is obtained by reducing the angle of the top of the floor piece opposed in a C shape to a hangar provided at the corner of a gymnasium, for example, a plurality of divided floor pieces. Are housed in an upright state.
[0006]
And when using the foldable movable floor equipment, the floor pieces in the connected state are pulled out from the hangar, moved straight to the position where the stadium should be laid, and the two floor pieces opposed in a C shape Of the floor piece so that the angle between the top part of the floor and the lower part of one floor piece opposed in a C-shape and the lower part of the other floor piece opposed in an adjacent C-shape is enlarged. The lower parts are moved away from each other, that is, moved so that the floor pieces that are orthogonal at the time of storage are parallel to each other. At this time, the links, connecting members, and wheels of the plurality of floor pieces are hidden in the lower surface of the floor pieces, or stored in the depressions provided on the lower surface of the floor pieces or the side portions of the joint portions, It does not appear on the floor.
[0007]
[Problems to be solved by the invention]
However, when the conventional folding movable floor equipment is moved to a preset laying position, that is, as shown in FIG. 11, four other floor surfaces P1 that have been delivered from the hangar T are used as gymnasiums. When the other floor surface P1 is configured to move linearly in the loading / unloading direction, movement other than linear movement is not easy. There is a problem that time, labor, and labor are required, and there is a problem that the installation space of the hangar T must be taken into consideration so that it is not necessary to move the other floor surface P1 in a direction other than the loading / unloading direction. there were.
[0008]
Therefore, it is conceivable to change the wheels of the conventional foldable movable floor surface equipment to casters so that they can move freely. If you try to lay other floors in the layout, it is difficult to position, and there is a problem that it takes time and effort to finely move the foldable movable floor equipment for positioning. .

[0012]
DETAILED DESCRIPTION OF THE INVENTION
A stadium facility according to claim 1 of the present invention is a stadium facility for delivering another floor surface stored in a hangar and laying the other floor surface on the floor surface. Is provided at one end of each of the even number of floor pieces obtained by dividing the other floor surface and the opposing surfaces of the pair of floor pieces, and the angle formed by one end of the opposing floor pieces can be freely expanded and reduced. The first folding mechanism, and the other end of one of the two pieces in a pair and the other end of the other piece in a pair of two adjacent to each other, A second bending mechanism capable of expanding and contracting an angle formed between the other end of the floor piece and the other end of the other floor piece adjacent thereto, and a caster provided at least under the second bending mechanism. The hangar has a moving mechanism for moving another floor surface in the loading / unloading direction on the floor in the hangar, and is mounted on the moving mechanism. Has a pivoting arm which is hung over the one edge of the, in which a pivoting mechanism for pivoting by an angle that is set to another floor by driving the swivel arm.
[0013]
According to the above configuration, when the other floor surface in the stadium facility is not in use, the first folding mechanism is folded so that the angle formed between the ends of the opposing surfaces of the pair of floor pieces is reduced. And the second bent so that the angle formed between the other end of one of the pair of two pieces and the other end of the other piece of the two adjacent pairs is reduced. A plurality of floor pieces are stacked and stored in the hangar in a state where the mechanism is folded, that is, in a state where the surface of the floor pieces is raised in a direction perpendicular to the floor surface.
[0014]
The other floor surface in the state of being stored in the hangar can be moved in the warehousing direction by the moving mechanism provided on the floor in the hangar, and is mounted on this moving mechanism. The turning mechanism can be turned. Then, for example, in order to unload and lay four other floors from four sides, that is, from four hangars, to the center of the gymnasium, the following operation is performed.
[0015]
When the moving mechanism is driven, the other floor surface in the hangar moves in the direction of delivery. For example, at this time, the first and second folding mechanisms are operated so that the other folded floor surface is the floor surface. Parallel to. That is, when the second bending mechanism is operated, the other floor piece of one pair of two pieces and the other floor piece of a pair of two pieces adjacent to the other end of the floor piece. Are separated from each other.
[0016]
When the other ends of the floor pieces are separated from each other, the other end of one of the two pieces as a pair and the other end of the other floor piece as a pair of two adjacent to the other end Increases the angle formed. At this time, the first bending mechanism is operated, and the angle formed between the ends of the opposing surfaces of the floor pieces that are a pair of the two pieces is enlarged. In this way, the other floor surface changes from a state of rising in a direction orthogonal to the floor surface to a parallel state.
[0017]
Then, the other floor surface that has been delivered from the hangar and made parallel to the floor surface is then pivoted toward the center of the gymnasium by the pivot mechanism. In other words, since the turning mechanism is mounted on the moving mechanism, the moving mechanism moves the other floor surface along with the other floor surface, and spans between the mounting location and one edge of the other floor surface. The swivel arm is in a state of being unloaded from the hangar. Then, by rotating the pivot arm at a preset angle, the other floor is pivoted to the center of the gymnasium and positioned.
[0018]
In this way, when the other three floors are also removed from the hangar and turned toward the center of the gymnasium, the other four floors will be laid without gaps, and positioning will be performed. There is no need to make fine adjustments, and other floors can be easily and quickly moved to a predetermined laying location. In addition, in order to enter another floor surface in the hangar, the above procedure may be reversed, and in this case, the floor can be easily and quickly received.
[0019]
By the way, the above-described stadium equipment according to claim 1 of the present invention is suitable for use when laying another floor surface with a preset laying layout, and to further improve the flexibility of the laying layout. What is necessary is just to comprise as follows.
[0020]
That is, in the stadium facility according to claim 2 of the present invention, in order to lay another floor surface on the floor surface, the other floor surface is provided with an even number of floor pieces constituting the other floor surface, A first bending mechanism that is provided at one end of each of the opposing surfaces of the pair of floor pieces, and that allows the angle between the ends of the opposing floor pieces to be freely expanded and contracted, and one of the two pieces as a pair. The other end of the floor piece and the other end of the other floor piece that is adjacent to the other floor piece, and the other end of the other floor piece adjacent to the other floor piece are provided. Freely expand and contract angles The pivot member is provided on the outer surface of the plate on the back side of the one and the other floor pieces. The second bending mechanism and the lower part of the second bending mechanism are provided, and the whole is levitated by injecting the sucked air onto the floor surface to generate a thin air film between the floor surface and the second bending mechanism. With levitation device The levitation device is pivotally supported by the pivot members, and the other end is pivotally supported at both ends of the second link at a position below the portion where the pivot members are pivotally supported. Store one end of the first link in a pivotally supported housing It is a thing.
[0021]
According to the above configuration, when the other floor surface in the stadium facility is not in use, the first folding mechanism is folded so that the angle formed between the ends of the opposing surfaces of the pair of floor pieces is reduced. And the second folding mechanism is configured to reduce the angle formed between the other end of one of the two floor pieces and the other end of the other of the two adjacent floor pieces. A plurality of floor pieces are stacked in a folded state, that is, with the surface of the floor pieces raised in a direction perpendicular to the floor surface, and stored in, for example, one hangar.
[0022]
For example, when four other floor surfaces are delivered and laid to the center of a gymnasium, the following operation is performed. When the levitation device is operated, the sucked air is jetted to the floor surface at the lower part of the second folding mechanism, and a thin film of air is generated between the floor surface and the other floor surface is lifted. And it will be in the state which can be taken out from a hangar easily. That is, since the movement of other floor surfaces is easy and no effort is required for the movement, at least one hangar is sufficient regardless of the distance between the laying positions.
[0023]
The other floor surface unloaded from the hangar is moved to the laying position while being lifted to the position to be laid, and at the laying position, as described above, by the first and second folding mechanisms, On the other hand, the state is gradually changed from the state of rising in the orthogonal direction to the parallel state.
[0024]
After the other floor surface is in a completely parallel state and finely adjusted the laying position, the levitation device is stopped, and the other floor surface that has floated is lowered to the floor surface. In this state, another floor surface is laid on the floor surface. To store from this state, the above operation may be reversed. As described above, the stadium equipment according to claim 2 of the present invention can be easily performed by one worker until the other floor surface is taken out from the hangar, moved, and laid. Sometimes the entire stadium equipment is surfaced, so it can be quickly moved to any laying position.
[0025]
In the stadium facility according to claim 2, since the caster in the stadium facility according to claim 1 is replaced with a levitation device, other floors may be moved more easily and freely. However, on the other hand, there is a possibility that a problem that positioning becomes difficult may occur. The stadium facility according to claim 2 is unsuitable for positioning at a time without precisely adjusting the laying position set in advance, but is movable and quick, and requires a large amount of labor for the movement. Therefore, even if it is necessary to perform fine adjustment for positioning, the labor, time, and labor required for fine adjustment are extremely small, so that positioning does not become difficult.
[0026]

[0029]
The first bending mechanism 3 is provided with pivot members 3a and 3a on the opposing surfaces of the plate members 2b and 2b of the floor pieces 2 and 2 having a pair of two pieces, and a link 3b between the pivot members 3a and 3a. Is supported. The pivot members 3a and 3a are provided with leg portions 3c and 3c, respectively. Cushioning materials 3d, 3d made of, for example, rubber for cushioning, which also serve as a slip stopper, are provided at the ends of the legs 3c, 3c opposite to the pivotal support portions.
[0030]
In addition, the floor piece 2 is connected to the other end of one of the two floor pieces 2 and the other end of the other floor piece 2 of the two adjacent pieces. A second bending mechanism 4 is provided that allows the angle between the other end of the floor piece 2 and the other end of the other floor piece 2 adjacent thereto to be freely expanded and contracted.
[0031]
The second bending mechanism 4 is provided with a pivot member on the outer surface of each plate member 2b of one floor piece 2 of a pair of two pieces and the other floor piece 2 of a pair of two adjacent pieces. 4a and 4a are provided, respectively, and the pivot members 4a and 4a pivotally support a part of casings C1 and C1 in which casters C described later are accommodated. Further, one ends of the links 4b and 4b are pivotally supported at positions below the portions pivotally supported by the pivot members 4a and 4a in the casings C1 and C1, respectively. The other ends of the links 4b and 4b pivotally support both ends of the link 4c.
[0032]
One end of each of the links 5 and 5 having the same length is pivotally supported at the same position on the opposing surface of the plate members 2b and 2b of the floor pieces 2 and 2 as a pair. The other ends of 5 and 5 are pivotally supported by a shaft 5a. By rotating the pivot shaft of the link 5 on either one of the links 5 and 5 by the drive motor 5b, the angle formed by the links 5 and 5 about the shaft 5a is changed, whereby the first folding is performed. Centering on the mechanism 3, the floor pieces 2 and 2 are symmetrically parallel to the floor surface P or folded orthogonally.
[0033]
Further, the leg members 6 and 6 are respectively located at the same position on the opposing surfaces of the plate members 2b and 2b of the floor pieces 2 and 2 as a pair, for example, at positions between one end of the floor piece 2 and the other end. Is provided. One end of the leg member 6 is pivotally supported by a pivotal support member 2c provided on the plate member 2b of the floor piece 2, and the other end is provided with a cushioning material 6a made of, for example, rubber for cushioning which also serves as a slip stopper. Is provided.
[0034]
The leg member 6 and the leg part 3c each pivotally support a link member 6A at an intermediate position thereof. The link member 6A accommodates one end at an intermediate position of the leg part 3c and the other end at a caster C. A part of the casing C1 of the moving member is pivotally supported at the same position as the position where the link 4b is pivotally supported. When the floor piece 2 becomes parallel to the floor surface P by the link member 6A, the leg member 6 and the leg portion 3c are synchronously orthogonal to the floor surface P, and are thus perpendicular to the floor surface P. The floor piece 2 is supported on the floor surface P while maintaining the vertical state.
[0035]
Further, the link member 6 </ b> A is parallel to the floor piece 2 in synchronism with the leg member 6 and the leg portion 3 c when the floor piece 2 is orthogonal to the floor surface P. Thus, by providing the link member 6A, the leg member 6 and the leg 3c can be stably erected on the floor surface P.
[0036]
Further, at the lower part of the second bending mechanism 4, that is, between the floor surface P and the outer surface of the plate member 2 b of the floor piece 2, a caster C is placed in a casing C 1 that is always in parallel with the floor surface P. Is provided.
[0037]
Subsequently, the hangar T1 in the stadium facility 1 of the present invention is configured as follows. Reference numeral 11 denotes a moving mechanism that is provided on the floor of the hangar T1 and moves the above-described other floor surface P2 in the loading / unloading direction. The moving mechanism 11 has two traveling rails 11a laid in the loading / unloading direction on both ends in the width direction orthogonal to the loading / unloading direction and on the floor of the storage T1 at an intermediate position. On the upper side, a movable carriage 11b having wheels on its lower surface is placed, and the movable carriage 11b is moved.
[0038]
As for the mobile trolley | bogie 11b, the edge part of the chain 11c is each attached to the both ends of the loading / unloading direction. The chain 11c is hung on a sprocket 11d provided at the back position in the loading / unloading direction and the loading / unloading port position in the storage T1. Furthermore, the shaft 11e is provided in the sprocket 11d provided in the storage / receipt direction back position in the storage T1.
[0039]
Further, among the sprockets 11d provided at the back position in the loading / unloading direction in the hangar T1, a drive rotating around the shaft 11e is located at a position adjacent to the sprocket 11d provided at an intermediate position in the width direction orthogonal to the loading / unloading direction. A sprocket 11f is provided. Further, the moving mechanism 11 has a drive motor 11g for rotationally driving the drive sprocket 11f.
[0040]
A drive chain 11h is mounted on a sprocket (no reference number) provided on the output shaft of the drive motor 11g and the drive sprocket 11f. When the drive motor 11g is driven, the drive sprocket 11f is connected via the drive chain 11h. Rotates and rotates this drive sprocket 11f.
[0041]
As the drive sprocket 11f rotates, the three sprockets 11d provided at the back position in the loading / unloading direction in the storage T1 via the shaft 11e rotate simultaneously, and in the loading / unloading direction in the storage T1 via each chain 11c. Each sprocket 11d provided at the entrance / exit position rotates.
[0042]
Then, the movement of the chain 11c due to the rotation of the sprocket 11d causes the three movable carriages 11b to move simultaneously along the traveling rail 11a in the loading / unloading direction in the hangar T1, and together with the turning mechanism 12 described later, the other floor surface P2 is moved to the hangar T1. The goods are issued from or received from.
[0043]
Further, on each moving carriage 11b in the moving mechanism 11, a turning mechanism 12 for turning the other floor surface P2 on the floor surface P is mounted. In the other floor surface P2 closest to the hangar T1, the swivel mechanism 12 is provided with a swivel arm 12a whose one end is pivotally supported on the casing C1 in which the caster C is housed, and the other end of the swivel arm 12a. And a rotating shaft 12b that rotates.
[0044]
Since the turning mechanism 12 simultaneously turns the turning arm 12a mounted on the movable carriage 11b located at three positions as described above in the direction orthogonal to the loading / unloading direction, one end and the other end of the turning arm 12a The link arm 12c is pivotally supported at an intermediate position.
[0045]
A turning motor 12d for rotationally driving the turning shaft 12b is provided along with the turning shaft 12b on the movable carriage 11b arranged at an intermediate position in the direction orthogonal to the loading / unloading direction. A swing chain 12e is hung on the motor 12d and the swing shaft 12b.
[0046]
That is, in the turning mechanism 12, when the turning motor 12d is driven, the turning shaft 12b is turned through the turning chain 12e, and three turning arms 12a are turned simultaneously by the link arm 12c.
[0047]
Next, operation | movement of the stadium equipment 1 of the said structure is demonstrated.
As shown in FIG. 6, the hangar T <b> 1 is elevating, for example, and is provided at each of the four corners of the floor P of the gymnasium. The hangar T1 is lowered when the other floor surface P2 is not used and after the other floor surface P2 is delivered, and when the hangar T1 is lowered, the upper surface of the hangar T1 is a gymnasium. It can be used as a part of the floor surface P.
[0048]
And in order to deliver the other floor surface P2, first, the hangar T1 is raised from the above-described state, and the floor of the hangar T1 and the floor surface P of the gymnasium are flush with each other (FIG. 6A). Thus, the drive motor 11g of the moving mechanism 11 is driven, and the drive motor 5b is driven so that the angles of the links 5 and 5 disposed between the floor pieces 2 and 2 are enlarged.
[0049]
When the drive motor 11g of the moving mechanism 11 is driven to rotate forward, the moving carriage 11b moves in the exit direction as described above, whereby the other floor surface P2 is exited from the storage T1. Then, the angle formed between the links 5 and 5 begins to gradually increase by the drive motor 5b that drives the link 5, and along with this, the angle formed between the ends of the pair of floor pieces 2 is first. The angle between the other end of the floor piece 2 that is enlarged by the bending mechanism 3 and that is a pair of two pieces and the other other end of the floor piece 2 that is a pair of two pieces is the second bending point. Enlarging by the mechanism 4, the floor piece 2 gradually becomes parallel to the floor surface P.
[0050]
At this time, the leg 3c and the leg member 6 in the first bending mechanism 3 are moved relative to each other so as to maintain a vertical state with respect to the floor surface P by the link member 6A, and the floor piece 2 is moved to the floor surface P. When it becomes parallel with respect to, it will contact the floor surface P and will support the floor piece 2. On the other hand, the casing C1 in which the casters C are housed is pivotally supported by the pivot member 4a, so that the parallel state with respect to the floor surface P is always maintained even when the floor piece 2 tilts as described above.
[0051]
Then, after the floor piece 2 is completely parallel to the floor surface P, the turning mechanism 12 is driven. Now, if the other floor surface P2 is simply moved linearly from the storage T1 in the exit direction, a gap is generated in the adjacent portion of the other four floor surfaces P2, so that the predetermined laying position is reached. The angle-set turning mechanism 12 is driven to move the other floor surface P2 to the center of the gymnasium so that the other floor surface P2 is turned.
[0052]
That is, when the turning motor 12d of the turning mechanism 12 is driven to rotate forward, all the turning arms 12a turn simultaneously via the link arm 12c, and the other floor surface P2 that pivotally supports one end of the turning arm 12a It moves to the center of the gymnasium by the turning angle of 12a, and each other floor surface P2 is positioned at this position (FIG. 6 (b)).
[0053]
Then, the turning arm 12a is removed from the casing C1 on the other floor surface P2, the drive motor 11g of the moving mechanism 11 is driven in reverse, the turning mechanism 12 and the moving mechanism 11 themselves are returned into the storage T1, and the storage T1 is lowered. Thus, the other floor surface P2 can be used.
[0054]
In order to store the other floor surface P2 in the hangar T1, after the hangar T1 is raised, the drive motor 11g is driven to rotate forward to move the movable carriage 11b and the turning mechanism 12 to the entrance / exit, and the center of the gymnasium For each of the other floor surfaces P2 located at 1, reattach one end of the swivel arm 12a removed as described above and drive the swivel motor 12d in the reverse direction to swivel the other floor surface P2 in the opposite direction. Thereafter, the drive motor 11g is driven in reverse to store the other floor surface P2 in the storage T1, and the storage T1 is lowered.
[0055]
Thus, in the stadium facility 1 corresponding to claim 1 of the present invention, when the moving mechanism 11 makes it easy to enter and exit the other floor surface P2, and when moving within a predetermined laying range, The turning mechanism 12 makes positioning easy and reliable.
[0056]
Next, the stadium facility 20 corresponding to claim 2 will be described. As shown in FIGS. 7 to 10, the stadium facility 20 uses the casters C in the stadium facility 1 on the other floor surface P <b> 2 described above. In addition to the point that the other floor surface P3 is floated on P, the hangar T2 is different in that the moving mechanism 11 and the turning mechanism 12 are omitted. In the stadium facility 20, the same components as those in the stadium facility 1 are denoted by the same reference numerals in the drawing, and the description of the configuration of the stadium facility 20 is omitted.
[0057]
In the stadium facility 20, the levitation device 7 is provided below the second bending mechanism 4. In other words, the levitation device 7 receives air from a power supply device (not shown), sucks air from the suction port 7a, discharges it from the discharge port 7b, and places the blower 7A on the discharge port 7A. It consists of a casing 7B to which an exhaust pipe 7c connected to 7b is connected. The housing 7 </ b> B is configured so as to be always parallel to the floor surface P at a position between the floor surface P and the outer surface of the plate member 2 b of the floor piece 2.
[0058]
In order to temporarily store the air on the back surface side of the housing 7B and inject it evenly over the entire back surface of the housing 7B, the air flows in, as shown in FIGS. 9 (a) to 9 (b), In addition, although not shown, an injection portion 7d in which a large number of holes are formed is provided on the back surface.
[0059]
Further, the casing 7B is partially supported by the same axis as the pivot member 4a in the second bending mechanism 4 described above, and always maintains a parallel state with the floor surface P, and the other floor surface P3. It also has a function as a leg for supporting the floor piece 2 when laying.
[0060]
Next, the operation of the stadium facility 20 of the present invention will be described.
For example, in a gymnasium, as shown in FIG. 10, one hangar T2 is provided at an indoor corner, and the stadium facility 20 of the present invention can be moved freely, so that only one hangar T2 is required. This is a great advantage.
[0061]
Then, the other floor surface P3 is folded in the hangar T2, that is, the angle formed between the ends of the two floor pieces 2 paired is reduced by the first folding mechanism 3, and the two are paired. The angle formed between one other end of the floor piece 2 and the other other end of the pair of floor pieces 2 is reduced by the second folding mechanism 4, and the floor piece 2 becomes the floor surface P. It is stored in a state where it stands upright vertically.
[0062]
Further, the hangar T2 is stored in a state where it is lowered to the lower surface of the floor surface P as shown in FIG. 1 when not in use, and rises up to above the floor surface P when in use. To use the other floor surface P3, the hangar T2 is raised, a power switch (not shown) is turned on, and the blower 7A of the levitation device 7 is operated. When the blower 7A is actuated, air is sucked from the suction port 7a, air is ejected from the discharge port 7b, and is sent to the ejection unit 7d through the exhaust pipe 7c.
[0063]
In the injection part 7d, before air is sent in, it is in a crushed state as shown in FIG. 9A, and when air is sent in, it expands as shown in FIG. Air is ejected from the holes, and a thin air film is generated between the holes and the other floor surface P3 is raised from the floor surface P.
[0064]
Then, the entire other floor surface P3 is taken out from the hangar T2 and moved to an arbitrary position in the gymnasium. After moving to the laying place of the other floor surface P3, the drive motor 5b is driven to increase the angle formed by the links 5, 5, and the first and second folding mechanisms 3, 4 are operated to move the other floor. The surface P3 is parallel to the floor surface P. At this time, since the casing 7B of the levitation device 7 is pivotally supported by the pivot member 4a, the casing 7B of the levitation device 7 always stays on the floor surface P even if the floor piece 2 tilts as described above. The parallel state is maintained.
[0065]
Then, after the other floor surface P3 is made completely parallel to the floor surface P, the laying position of the entire other floor surface P3 is finely adjusted, and the levitation device 7 is stopped. When the levitation device 7 is stopped, the entire other floor surface P3 descends on the floor surface P, and thus the other floor surface P3 is laid on the floor surface P. Note that there is no gap in the tatami mat 2a between the floor pieces 2, and various members provided on the plate 2b side of the floor piece 2 do not appear on the surface of the tatami mat 2a. In order to store the other floor surface P3 in the hangar T2, the reverse operation described above may be performed.
[0066]
Thus, when the stadium facility 20 according to claim 2 of the present invention lays another floor surface P3 on the floor surface P, the other floor surface P3 is levitated from the floor surface P by the levitating device 7. Therefore, even one worker can easily lay another floor surface P3, and can quickly and arbitrarily lay it at an arbitrary position.
[0067]
In the above-described embodiment, a stadium for judo was laid as the other floors P2 and P3, so the tatami 2a was provided on the surface side of the floor piece 2, but instead of this, For example, a member for laying a hard court for tennis, or if a dedicated court or stadium is required for a competition, a part of the floor 2 where the tatami 2a is provided can be changed to change to a gymnasium or sports In addition to being widely used in the facility, a temporary stage can also be set up.

【The invention's effect】
As described above, the stadium facility according to claim 1 of the present invention is an even number of floor pieces obtained by dividing the other floor surface on the other floor surface, and the floor piece is folded or connected in a state where these floor pieces are connected. The first and second bending mechanisms that are parallel to the surface, and casters that freely move other floor surfaces on the floor surface, and the hangar has other in the storage direction on the floor in the hangar It is equipped with a moving mechanism that moves the floor surface and a turning mechanism that turns the other floor surface by a set angle. Therefore, labor is required when laying another floor surface in a preset laying layout. Therefore, the positioning can be performed quickly and reliably, and the laying work of other floors becomes extremely easy.
[0069]
In addition, the stadium facility according to claim 2 of the present invention is an even number of floor pieces obtained by dividing the other floor surface on another floor surface, and these floor pieces are folded or connected to the floor surface. The first and second bending mechanisms that are parallel to each other and the levitation device that injects air to the floor surface and floats, so that the movement of the other floor surface is extremely easy, and any Other floors can be laid at the location.
