The competition in the competition field 2 can be visually observed from the inside of the management room 13 through the window 13b.
As shown in FIG. 2B, a passage 14 and a staircase 15 are provided below the stand spectator seat 10. The rear end portion of the floor portion 22 of the middle stage spectator seat portion 21 is substantially the same height as the bottom floor surface of the stairs 15, and it is possible to enter and exit the middle tier seat portion 21 from the passage 14 and the stairs 15. ing.

[Second usage pattern]
When changing from the athletics viewing mode to the ball game viewing mode, as shown in FIG. 4, the lifting device 31 is extended to raise the lifting platform 32 to a height equivalent to the competition field 2. Further, after the lifting platform 32 is raised or simultaneously, the support rod 33 is extended to further raise the middle spectator seat 21. A plate-shaped track curing material 4 is laid on the track 2b. The middle spectator seat 21 is raised to a height at which the rear end thereof is continuous with the front end of the stand spectator seat 10. Specifically, the level difference between the floor 22 at the rear end of the middle spectator seat 21 and the floor 11 at the front end of the stand spectator seat 10 is made equal to the height of the stairs that can be visited by the spectator.
When the movable spectator seat unit 20 is raised to the high seat position, the front spectator seat 22 is advanced from the lower position of the middle spectator seat 21 to the front position. As shown in FIG. 3, when the front spectator seat 22 moves to the front position (installation position), the front spectator seat 22 is fixed and the spectator seat 26 is raised. Then, the handrail 5 is attached to the front end of the front spectator seat 22. Thereby, the ball game viewing mode (long-distance watching mode) is completed.

According to such a configuration, the movable spectator seat unit 20 has a two-layer structure, and the number of spectators can be increased as compared with the normal athletics viewing mode.

According to the spectator seat structure 1 according to the present embodiment, the occurrence of a parting seat can be reduced even in the case of viewing a competition at a position close to the spectator seat (track 2b) in the athletics viewing mode. Below, the effect obtained by the spectator seat structure 1 is demonstrated.
As shown in FIG. 1, in the athletics viewing mode, the front part of the movable spectator seat unit 20 is accommodated in the movable spectator seat accommodating part 50 and positioned below the competition field 2. The position of the eye E of the spectator at 20 is lowered. As a result, the audience's line of sight increases (the inclination of the line of sight decreases), so that even when viewing a track competition near the spectator seat, the head of the audience in the front row does not get in the way and the site line L is secured. be able to. Therefore, the occurrence of a parting seat can be reduced. In the spectator seat 12 of the stand spectator seat portion 10, the site line L can be secured because it is high from the competition field 2 and the inclination angle of the floor portion 11 is steep. Therefore, the occurrence of a parting seat can be reduced.
Further, when the movable spectator seat unit 20 is at a low position, there is a vertical gap between the front end portion of the stand spectator seat portion 10 and the rear end portion of the movable spectator seat unit 20 (middle spectator seat portion 21). It is formed. By providing the window 13b of the management room 13 in the gap, the competition can be visually observed from the management room. If a door (not shown) is still provided, a flow line from the operation room 13 to the competition field 2 can be secured.
Further, by providing a passage 14 and a staircase 15 below the stand spectator seat 10 at the rear of the movable spectator seat unit 20, the spectator flow line of the stand spectator seat unit 10 and the spectator flow line of the movable spectator seat unit 20 are separated. As a result, the spectator can move smoothly and congestion of the evacuation route in an emergency can be reduced.

As shown in FIG. 3, in the ball game viewing mode, the object to be viewed is often a long distance, so the audience seats 24 and 26 of the movable audience seat unit 20 are not accommodated in the movable audience seat accommodation section 50. Can increase the line of sight. Therefore, the head of the audience in the front row does not get in the way and the site line L can be secured, so the occurrence of a parting seat can be reduced. Moreover, since the position of the eyes of the spectators in the middle spectator seat part 21 is high, it is possible to look over to a distant part of the competition field.
Further, in the ball game viewing mode, the rear end of the middle spectator seat 21 is continuous with the front end of the stand spectator seat 10, and the rear end of the front spectator seat 22 is continuous with the front end of the middle spectator seat 21. Therefore, the audience can smoothly move between the stand audience seat part 10 and the middle audience seat part 21 and between the middle audience seat part 21 and the front audience seat part 22. .

On the other hand, in this spectator seat structure 1, the front spectator seat portion 22 disposed in front of the middle tier seat portion 21 is provided to be movable back and forth, and is movable in a state of being located below the middle tier seat portion 21 when not in use. By accommodating in the spectator seat accommodating part 50, the following effects are obtained. According to such a configuration, when the front spectator seat 22 is used (in the case of the ball game viewing mode), the spectator seat 26 of the front spectator seat 22 can be brought closer to the competition field 2, which is powerful. Watch sports. When the front spectator seat unit 22 is not used (track and field watching mode and event viewing mode), it is accommodated in the lower part of the middle spectator seat unit 21 so that it does not get in the way.
Furthermore, the floor 23 of the middle spectator seat 21 and the floor 25 of the front spectator seat 22 have an integral structure that does not deform, so that rigidity can be secured over the entire floor. Therefore, it is possible to resist floor vibration caused by the audience jumping. In addition, since the movable mechanism of the movable spectator seat unit 20 can be simplified, maintenance is easy. Furthermore, the switching operation of each arrangement of the spectator seats can be easily performed by moving the movable spectator seat unit 20 up and down and moving the front spectator seat unit 22 back and forth.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not the meaning limited to the said embodiment, A design change is possible suitably in the range which does not deviate from the meaning of this invention. For example, in the above embodiment, when the lifting platform 32 is at the lowest position, the rear part of the movable spectator seat unit 20 is exposed from the movable spectator seat accommodating unit 50, which is in the athletics viewing mode. The configuration of the movable spectator seat accommodating unit 50 is not limited to such a configuration. It is good also as a structure which can form the movable audience seat accommodating part 50 further deeply, and can accommodate the movable audience seat unit 20 in the movable audience seat accommodating part 50 completely. In this case, if a cover member is provided to cover the upper opening of the movable spectator seat accommodating portion 50, a wider competition space can be secured than the track 2b and the field 2a for athletics. In addition, it is possible to easily install the stage 3 and the like in the event viewing mode.
