A lower support plate 37 is provided above the lower end plate 32, and the fan is mounted on the seat member 43 and is sandwiched between the lower support plate 37 and the lower end plate 32. Further, a through hole (not shown) for supplying air to the fan 42 is formed in the lower end plate 32 and the lower support plate 37, and the fan 42 and the wiring (not shown) are provided between the lower end plate 32 and the lower support plate 37. Is provided with a columnar protective frame 44 for protecting the frame.

  On the upper end plate 31 of the frame 30, the center of the upper surface portion 24 of the balloon 2 is detachably engaged with the upper end plate 31 from outside the balloon 2 by engaging means. The center of the lower surface 25 of the balloon 2 is connected by a connecting means 26 that can be opened and closed from the outside of the balloon 2, for example, a slide fastener.

  Next, a preferred embodiment of the display according to the present invention will be described.

  FIG. 4 is a front view showing the balloon 2 in which the display body 12 is installed by velvet fasteners 45 and 46 as hook-and-loop fasteners. The balloon 2 is composed of the body sheet 21 and the upper and lower two-sided sheets 22 and 23 as described above, and a female velvet fastener 45 as a detachable means is sewn on the outer periphery of the display body 12 on the surface of the body sheet 21 Have been. On the other hand, for example, a display such as "under construction" or "caution" is formed on the front surface of the display body 12 by means such as printing or pasting, and a male velvet is formed on the back surface of the display body 12 on the outer periphery thereof. A fastener 46 is sewn. The display body 12 can be installed on the surface of the balloon 2 by engaging the male velvet fastener 46 with the female velvet fastener 45 provided on the surface of the body sheet 21 of the balloon 2.

  In this way, the display body 12 can be detachably mounted on the surface of the balloon 2, so that the display can be easily changed, and only the display body according to the use need be prepared, which is economical. . Note that the velvet fasteners 45 and 46 need only correspond to the front surface of the balloon 2 and the back surface of the display body 12, and in order to further improve the adhesion, the velvet fasteners 45 and 46 can be changed or increased as needed. is there.

  Like the balloon 2, the display body 12 is made of a synthetic resin sheet material having light projecting property, durability and strength, for example, nylon 66 or the like. The display 12 may be made of a sheet of the same color as the sheet constituting the balloon 2 or a sheet of a different color. By configuring the display body 12 with a color different from that of the sheet constituting the balloon, the display body 12 can be made more prominent, so that the visibility can be improved and the surroundings can be better alerted. Further, the display body 12 may be a light-shielding body made of a light-shielding sheet. As the light shield, a cloth such as a blackout curtain, a plastic or metal plate, or the like can be used. By doing so, the light projecting range of the balloon 2 can be selected and set as appropriate, so that unnecessary light projecting to the private house can be shielded, thereby preventing trouble in the neighborhood.
