  A first embodiment of the present invention will be described with reference to the accompanying drawings. The aerial swimming simulation experience apparatus shown in FIGS. 1 and 2 has a columnar shape with a predetermined height as a whole. A mortar-shaped swimming chamber 12 as a swimming space surrounded by the inner wall 10 is formed inside the cylinder. A floor mat 2 having A protective net 7 is stretched over the upper end opening 14 of the swimming chamber 12 so that the swimmer 8 does not jump out of the swimming chamber 12. In the present embodiment, the soft rubber floor mat 2 is used for the bottom surface 13 at the lower end. However, the present invention is not limited to this, and another net-like material may be stretched.

  A plurality of blowers 1 for generating an updraft are arranged in parallel at the lower part of the floor mat 2, and an intake passage 18 having a predetermined width is formed between the lower surface and the bottom inner surface 17. At the lower end portion of the outer wall 19, an intake port 16 having a louver communicating with the intake passage 18 is formed. Outside air is sucked from here and sent to the blower 1 through the intake passage 18.

That is, according to the configuration of the present embodiment, it is possible to enjoy aerial swimming with a large number of people regardless of the weight and skill of each swimmer.

  A second embodiment of the present invention will be described with reference to the accompanying drawings. The aerial swimming simulation experience apparatus shown in FIG. 3 has a cylindrical shape with a predetermined height as a whole. A swimming chamber 12 on a tube having a top end opening 14 wider than a bottom bottom surface portion 13 is formed as a swimming space surrounded by the inner wall 10 inside the cylinder, and a plurality of bottom bottom surface portions 13 of the swimming chamber 12 are provided. The floor mat 2 having a cushioning property made of soft rubber and provided with the air blowing holes 3 is laid. A protective net 7 is stretched over the upper end opening 14 of the swimming chamber 12 so that the swimmer 8 does not jump out of the swimming chamber 12. In the present embodiment, the soft rubber floor mat 2 is used for the bottom surface 13 at the lower end. However, the present invention is not limited to this, and another net-like material may be stretched.

  A plurality of blowers 1 for generating an updraft are arranged in parallel at the lower part of the floor mat 2, and an intake passage 18 having a predetermined width is formed between the lower surface and the bottom inner surface 17. At the lower end portion of the outer wall 19, an intake port 16 having a louver communicating with the intake passage 18 is formed. Outside air is sucked from here and sent to the blower 1 through the intake passage 18.

  In the present embodiment, four blowers 1 are arranged side by side in the same plane, but the number is not limited.

  In the swimming chamber 12, retreat layers 15 a and 15 b each having a step portion 5 on which the swimmer 8 can retreat are formed in the inner wall 10 so as to have an annular groove shape along the circumferential direction. A plurality of the retreat layers 15a and 15b are arranged in parallel in the vertical direction so that the swimming height can be selected, and the swimming suitable for the level is made possible. Note that the number of the retraction layers is not limited, and can be formed in a spiral shape. An air intake hole 4 for facilitating entry and exit of the swimmer 8 is provided in the vicinity of the lower portion of the step portion 5 so as to extend obliquely downward to the center side and communicates with the swimming chamber 12. Further, the air conditioning holes 11 are connected to the evacuation layers 15a and 15b.

  In the aerial swimming simulation experience apparatus configured as described above, when the blower 1 is operated, outside air is taken in from the intake port 16 and sent through the intake passage 18 from the blow hole 3 of the floor mat 2 into the swimming chamber 12. The sent outside air generates an updraft in the swimming chamber 12, passes through the swimming chamber 12, and is discharged from the upper end opening 14.
