B. Prior Art An advertising device using an aircraft (see Utility Model Application Publication No. 59-53393 and Publication No. 2-14079) which was previously developed by the present applicant is a combination of horizontal bars and vertical bars in a grid pattern. A large number of lamps were placed on the advertising member at equal distances and intervals, and a flashing computer caused each lamp to flash to display numbers, alphabets, katakana, etc.

C. Problems to be solved by the invention According to the above-mentioned conventional technology, since a grid-like body is used for the advertising member, the weight becomes heavy, and in addition, the grid-like body is directly supported on the aircraft body, which causes vibrations of the aircraft body. resonate. For this reason, there were problems such as the length of the advertising member was limited and the characters that could be displayed were limited to 6 to 10 characters. Also, advertisements could not be read directly below the display.

The present invention solves the above problems, and
By using a flexible strip instead of the grid, the advertising display can be made longer, and therefore more characters can be displayed, and it can be seen even directly below the display, and the strip can be folded. To provide an advertisement display body that can be towed while maintaining a horizontal state without bending or sagging.

D. Means for solving the problems In order to achieve the above object, the structure of the present invention is as follows. That is, a flexible strip on which an advertising display is attached, a main rod tied along the front end of the strip in the towing direction, and a gap parallel to the main rod and on the strip in the towing direction. a plurality of sub-rods tied together; a swing prevention wing attached to the upper front part of the band whose length direction is along the width direction of the band; and a swing prevention wing provided at the rear end of the band. U whose vertical cross section opens in the towing direction
The present invention includes a flapping prevention member that is shaped like a letter and has a wind catch that is perpendicular or concave to the towing direction of the band in plan view.

E Function The advertising display body is maintained in a horizontal state by the anti-sway wings, and kept in a horizontal state in the width direction by the band connected to the rear of the main rod and the anti-flapping member provided at the rear end. , is extended horizontally backward through the air, and advertisements are displayed using letter cloth, etc. affixed to the band.

F. Embodiment The present invention will be described below based on an embodiment shown in the drawings.

As shown in Figure 1, the advertising display of the present invention has a main rod 1 attached to the front end (front end in the towing direction).
, a band A consisting of a plurality of character display pieces 13 connected to the main rod, a swing prevention wing B attached to the front upper surface of the band, and the rear end of the band (rear end in the towing direction). A flapping prevention member 14 is provided.

The main rod 1 is made of a lightweight pipe, and has multiple locations along its length (four locations in the embodiment).
The aircraft is towed to an aircraft by a rope 3 that is secured to a lightweight metal clasp 4 provided in the aircraft. The main rod 1 has a plurality of rods (eight rods in the example) in the length direction.
The main rod tape 5 is engaged. That is, the main rod tape 5 has ring portions at its front end and rear end, and the front end ring portion is inserted through the main rod 1 and locked therein. The main rod 1 is connected to a hook provided at the tail of the aircraft via a bundle ring 2 to which the rope 3 is bundled, a wire 6, a safety ring (not shown), and the like. The main rod tapes 5 are connected to each other by a connecting tape 5a parallel to the main rod 1.

A clip 11 is attached to the tape 5 tied to the main rod 1.
A character display piece 13 is detachably connected to the sub-rod 12. The character display piece 13 is made up of a plurality of tapes 13a (eight tapes in the illustration) that are long in the front-rear direction.
and a transparent base fabric (not shown) on the surface of these tape rows.
It consists of a character cloth 13b attached via a letter cloth 13b. That is, the clip 11 is made of bent wire as shown in the third figure, and has a ring portion 11a into which the sub-rod 12 can be inserted.
and tape fixing parts 11 formed on both sides of the ring part.
It consists of b. The sub-rods 12 are inserted into the ring portion 11a, and a plurality of sub-rods (8 pieces shown) are inserted at equal intervals in the length direction of the sub-rods.
is fixed by the elastic restoring force of the ring portion 11a. The ring part of the tape 5 for the main rod is fixed to the stop part 11b on the front side (left side in FIG. 3), and the ring part of the tape 13a for the character display piece is fixed on the rear side (right side in FIG. 3). be done. In this way, a plurality of character display pieces 13a (10 in the first illustration) are detachably connected in series via the clips 11 and sub-rods 12 to form the band A.

The anti-sway wing B is as shown in Figures 1 and 5.
The horizontal wing 7 extends at both ends in the length direction, is curved upward at an angle of α=45°, and has a leading edge of β.
The horizontal blade 7 is fixed to the main rod 1 via a screw or the like with its length direction along the width direction of the band.

The flapping prevention member 14 is attached to the clip 11 and the secondary rod 12 at the rear of the band A as shown in the first and fourth figures.
connected via. This member 14 is the clip 1
1, and a wind receiver 14b connected to the rear end of the tape. Further, the wind catcher 14b is bent into a concave arc shape facing the towing direction of the band A in plan view, and has a vertical cross section of U.
It has a letter shape and is held by the tape 14a so that its opening faces toward the front.

The operating state will be explained above. The advertisement display body is towed by a light aircraft not shown, and the horizontal wings 7 of the anti-sway member B fixed to the main rod 1 provide lift force equivalent to the weight of the advertisement display body including the strip. , the warped wings 9 keep it horizontal and it moves forward without overturning. The warping angle α of the warping blade 8 is set to an angle that can prevent the advertisement display from rolling over, and the receding angle β is set to an appropriate value to prevent skidding. Further, the wind catcher 14b swells to contain the wind, and is given a resistance force to prevent the band A from flapping. Further, the resistance force applied to the wind catcher 14b serves to cause the band A to wave horizontally backward. Then, the display body is towed while keeping its width direction horizontal.

The band A according to this embodiment can be up to about 30 m long and can display up to 32 characters. Furthermore, since the band A is towed by the aircraft via the flexible wire 6 and rope 3, vibrations from the aircraft body are not transmitted, and the band A does not shake or flap.

In addition to the above, net bodies, non-porous sheet bodies, etc. can also be used as the flexible band body A of the present invention.

G. Effects of the invention As described above, the present invention includes a flexible band on which an advertising display is attached, a main rod that is tied along the width direction to the front end of the band in the towing direction, and a main rod that is parallel to the main rod. a plurality of sub-rods tied to the band at intervals in the towing direction; and a sway stopper attached to the front upper surface of the band, the length direction of which is aligned with the width direction of the band. a wing, and a wind turbine which is provided at the rear end of the band and has a U-shape with a vertical cross section opening in the towing direction, and is perpendicular to the towing direction of the band or has a concave arc shape when viewed from above. It includes an anti-flapping member having a receiver. Therefore, the weight of the advertisement display body can be reduced, and the length can be increased accordingly, allowing more characters to be displayed. In addition, since the belt is towed horizontally with the letters lying on its side, the advertising text can be read not only directly below but also from a distance. Furthermore, this advertising display has many advantages, including low material costs and the ability to use light aircraft, making operating costs significantly lower than helicopters.
