Further, since the ring body 18 is supported by being in contact with the ball 19, the rotation of the entire moving body 4 is stabilized.

  The partition panel 5 is suspended from the respective support arm portions 17 of the movable body 4. In order to suspend the partition panel 5, each support arm portion 17 is formed in a T shape, and as shown in FIG. 4, a suspension collar portion 17 a hangs down integrally. A hanging hole 17b is formed in the hanging hook portion 17a. As will be described later, the partition panel 5 has a width for partitioning between the show window wall 13 of the block body 3 and the guide wall 2, and the suspended lower end is a free end. The partition panel 5 is set to have a length such that the lower end, which is a free end, is close to the floor surface 8 of the passage 7.

  Next, the structure of the partition panel 5 will be described with reference to FIGS. In this embodiment, the partition panel 5 is formed by overlapping a plurality of panel pieces 21 side by side. The panel piece 21 has a small width obtained by dividing the space between the show window wall 13 and the guide wall 2 of the block body 3. The partition panel 5 can be formed by overlapping a plurality of panel pieces 21 having such a small width side by side, and the partition panel 5 formed in this way has the show window wall 13 as shown in FIG. And the guide wall 2 can be partitioned. Therefore, the partition panel 5 can block the flow of air inside and outside the building.

  As shown in FIG. 5, each panel piece 21 is formed integrally with a main body 22 extending in the vertical direction in a strip shape and an overlapping portion 23 extending in the width direction from the side end of the main body 22. Has been. The main body portion 22 is a portion that is suspended from the support arm portion 17, and a suspension hole 24 for suspension is formed in the upper portion. A suspension bolt 27 (see FIG. 4) is passed through the suspension hole 24 and the suspension hole 17 b of the support arm portion 17, and a nut is coupled to the penetration end of the bolt 27 to suspend the panel piece 21 from the support arm portion 17. be able to.

  In such suspension, the panel piece 21, that is, the partition panel 5 can be attached to and detached from the support arm portion 17, so that the panel piece 21 can be easily replaced. In addition, as a structure which attaches the panel piece 21 to the support arm part 17 detachably, members other than a volt | bolt and a nut can be used suitably. For example, a hook may be formed on the support arm portion 17 and the panel piece 21 may be hung by hanging on the hook.

  The overlapping portion 23 extends in the width direction from a side end portion of the main body portion 22 excluding a portion where the suspension hole 24 is formed. The length of the main body 22 is set so that the lower end of the main body 22 is close to the floor surface 8 of the passage 7 when suspended from the support arm 17. On the other hand, the length of the overlapping portion 23 may be set similarly to the main body portion 22 or may be set to be shorter than the main body portion 22.

  In the overlapping of the panel pieces 21, the overlapping portion 23 of the panel pieces 21 is overlapped with the main body portion 22 of the adjacent panel piece 21. In this superposition, the upper part of the superposition part 23 is connected to the main body part 22 of the adjacent panel piece 21. This connection can be performed by connecting the upper part of the overlapping part 23 and the main body part 22 of the panel piece 21 overlapping the overlapping part 23 with bolts and nuts. For this connection, a connection hole 25 is formed in the upper portion of the overlapping portion 23. In such connection with bolts and nuts, the adjacent panel pieces 21 can be separated from the overlapped state, so that each of the panel pieces 21 can be easily replaced.

  Further, since the upper portion of the overlapping portion 23 is connected to the adjacent main body portion 22, the other portions are simply overlapped with each other. Can pass between them. In addition, as a connection means of the main-body part 22 and the superposition part 23, other means, such as a hook-and-loop fastener, can be used.

  As described above, by overlapping the overlapping portion 23 of the panel piece 21 on the main body portion 22 of the adjacent panel piece 21, the wind does not escape from between the adjacent panel pieces 21. For this reason, even if the partition panel 5 is formed by overlapping a plurality of panel pieces 21, the air inside and outside the building will not escape through the circulation wind vent 1. Thereby, the air conditioning effect of a building can be maintained reliably. Thus, by being able to maintain the air conditioning effect of the building, energy for air conditioning can be saved, and environmental conservation can be improved.

  The panel piece 21 is formed of a transparent flexible resin sheet. As this resin, polyamides such as polyvinyl chloride, polyethylene, polypropylene, nylon, polyimide, methacrylic resin, butadiene / styrene resin, synthetic rubber, natural rubber, and other materials can be selected. The panel piece 21 preferably has a weight that maintains a state in which the panel piece 21 is suspended vertically from the support arm portion 17 when suspended from the support arm portion 17. Accordingly, the thickness of the panel piece 21 is selected so as to have such weight. Further, by using a transparent resin sheet as the panel piece 21, the entire partition panel 5 composed of the plurality of panel pieces 21 becomes transparent. For this reason, it is possible to ensure transparency and visibility when the circulating wind ventilator 1 passes.

  In the above embodiment, since the panel piece 21 is formed of a flexible resin sheet and is suspended from the support arm portion 17, the partition panel 5 is formed by overlapping the panel pieces 21. When a passerby contacts the partition panel 5, the partition panel 5 can be easily bent so as to escape from the passerby. For this reason, a passerby etc. are not pinched | interposed between the partition panel 5 and the guide wall 2, and safety improves. In particular, since only the upper portion of the overlapping portion 23 is connected to the main body portion 22 of the adjacent panel piece 21, a passerby or the like can pass through the overlapping portion 23 and the main body portion 22. For this reason, safety is further improved.

  Further, in this embodiment, since the partition panel 5 is suspended from the support arm portion 17, a simple structure can be achieved. For this reason, the assembly of the movable part including the partition panel 5 is facilitated and the replacement work of the partition panel 5 is facilitated. Furthermore, since the partition panel 5 is formed of a resin sheet, the weight is reduced, and a drive source for rotating the partition panel 5 can be reduced in size and power consumption can be reduced.

  As shown in FIGS. 1 to 3, the show window wall 13 has a cylindrical shape extending in the vertical direction, and is positioned with a gap G around the rotating body 11. The upper portion of the show window wall 13 is connected to the support arm portion 17 so as to be suspended from the support arm portion 17, thereby rotating with the rotation of the moving body 4. In order to suspend the show window wall 13, a suspending hole 44 is formed in the upper part of the show window wall 13. Bolts (not shown) are inserted into the suspension holes 44 in the same manner as the panel pieces 21, or hooks (not shown) provided on the support arm portions 17 are inserted, whereby the show window wall 13 is attached to the support arm portions 17. It can be detachably hung.

  The show window wall 13 is formed of a flexible resin sheet, and the entire show window wall 13 can be reduced in weight. Since the show window wall 13 is formed of a flexible resin, even if a passerby contacts the show window wall 13, the show window wall 13 can be easily recessed without cracking. For this reason, safety can be ensured.

  On the outer surface of the show window wall 13, a character such as a landscape and an image such as a character can be printed, whereby predetermined information can be displayed. Further, as the show window wall 13, a transparent flexible resin sheet can be selected. By making the show window wall 13 transparent, the inside of the show window wall 13 can be seen through. For this reason, goods etc. can be displayed in the inside of the gap G between the show window wall 13 and the rotator 11, and there is an advantage that merchandise advertising is possible.

  In this embodiment, as shown in FIGS. 1 and 4, a weight piece 30 is attached to the lower part of the partition panel 5. The weight piece 30 is formed by horizontally arranging weight piece portions 31 having a horizontal length corresponding to the panel pieces 21 of the partition panels 5. The weight piece portion 31 is detachably attached to the lower portion of the corresponding panel piece 21. Therefore, the length of the weight piece 30 including all the weight piece portions 31 is the same as the entire width of the lower portion of the partition panel 5 formed by overlapping the plurality of panel pieces 21. In this embodiment, the weight piece 30 including the plurality of weight piece portions 31 is detachably attached to both surfaces of the partition panel 5.

  As a structure for detachably attaching the weight piece portion 31 to the partition panel 5, with the weight piece portion 31 superimposed on the lower portion of the partition panel 5, a connection bolt 33 is passed through them, and a connection nut 34 is provided at the through end. This can be done by screwing. It is not limited to the bolt 33 and the nut 34 but may be detachably attached by a hook-and-loop fastener or other means.

  In such embodiment, since the weight piece part 31 is attached to the lower part of each panel piece 21, the weight of the panel piece 21 can be increased. For this reason, it is possible to reliably support the state in which each panel piece 21 is suspended in a vertical shape. Thereby, the whole partition panel 5 can be suspended vertically in a tension state. In order to perform such an action, the thickness of the weight piece portion 31 is appropriately set so that the weight piece portion 31 has a predetermined weight.

  As the weight piece portion 31, a flexible resin sheet similar to the panel piece 21 can be used. By using the flexible resin sheet, the flexibility of the entire partition panel 5 can be maintained even when the weight piece portion 31 is attached to the partition panel 5. For this reason, when a passerby etc. contact the partition panel 5, it can bend so that the partition panel 5 may escape. Further, in the structure in which the weight piece portion 31 is detachably attached to the panel piece 21, the weight piece portion 31 can be easily replaced. The weight piece 31 is preferably a transparent resin sheet from the perspective of transparency, but may be an opaque resin sheet.

  In the present invention, the weight piece 30 may be formed of a single horizontally long flexible resin sheet without being composed of the plurality of weight piece portions 31. In this case, the weight piece 30 is attached over the entire width of the lower part of the partition panel 21.

The base 38 is brought into contact with the lower end surface of the partition panel 5, and the brush body 37 is sandwiched between the weight pieces 31 of the weight pieces 30. In this state, the connecting bolt 41 is passed through the brush body 37 and the weight piece portion 31, and the connecting nut 42 is screwed into the penetrating end, whereby the brush body 37 can be detachably attached.

  The brush body 37 is attached so that the brush 39 is in contact with the floor surface 8 of the passage. By attaching such a brush body 37, the brush 39 slides on the floor surface 8 when the partition panel 5 rotates, so that the floor surface 8 can be cleaned. Further, since the brush body 37 is detachable, even if the brush body 37 is dirty, the dirty brush body 37 can be easily replaced.

  In addition, in this embodiment, since the brush body 37 is attached, the lower end of the partition panel 5 is in a state of being somewhat separated from the floor surface 8. Accordingly, the lower end of the weight piece portion 31 is brought close to the floor surface 8. Accordingly, the weight piece 30 (the weight piece 30 and the brush body 37) can block the air flow from between the floor surface 8 and the partition panel 5.

  In this embodiment, similarly to the first embodiment, a weight piece portion 31 is detachably attached to the lower portion of each panel piece 21. For the weight piece portion 31, a flexible resin sheet similar to the panel piece 21 can be used. The weight piece portion 31 can be attached by a bolt and nut, a hook-and-loop fastener, or other means. The weight piece portion 31 increases the weight of each panel piece 21. By attaching the weight piece portion 31, the panel piece 21 can be reliably maintained in a vertically suspended state. In addition, when the vertical suspended state can be ensured only by the panel piece 21, it is not necessary to attach the weight piece portion 31.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the first to third embodiments, the partition panel 5 may be formed by a single transparent flexible resin sheet without being formed by overlapping a plurality of panel pieces. Further, the partition panel 5 and the weight piece 30 may be fixed to the support frames 17 and 64 by bonding or welding without making the partition panel 5 and the weight piece 30 detachable, and the weight piece 30 is fixed to the partition panel 5 by bonding. May be. Further, the overlapping portion 23 of the panel piece 21 may be bonded to the main body portion 22 of the panel piece 21 over the entire length. Furthermore, the weight piece 30 and the brush body 37 may be omitted.
