Problems to be solved by the invention

  However, in the advertising device of Patent Document 2, since the balloon and the base share the internal space, the airflow for inflating the balloon is supplied to the common space from the outside via the blower. Accordingly, the air inlet of the blower is provided facing the outer wall of the base, and air is taken into the blower from the outside through the outer wall of the base. In the advertising device of Patent Document 2, the air inlet of the blower is provided on the bottom surface of the base.

  In this structure, dust and rain water droplets are sucked into the balloon from the outside through the blower, and the inner surface of the balloon becomes dirty, and the advertising effect is significantly impaired. If a filter is installed at the air intake of the blower, inhalation of dust etc. can be prevented, but if the outside air is accompanied by water droplets after rain or rain, the filter will easily clog, the air volume will be insufficient, and the balloon will be sufficient No levitation.

  Intrusion of dust and the like is mitigated by raising the bottom surface of the base, but clogging of the intake port remains a difficult problem only by the degree of loss.

  Further, in the advertising device of Patent Document 2, a combination of gears having different diameters and curvatures is used to rotate the balloon. If the rotation of the balloon is continued and repeated for a long period of time, the gear wears down, and the rotation of the balloon becomes unstable. In addition, tooth loss occurs and rotation is impossible.

  This type of advertising device is often used outdoors, and since the balloon receives wind from the side and receives a tilting force, the gear teeth tend to wear and deform diagonally, resulting in poor meshing. Finally, it becomes impossible to rotate.

  An object of the present invention is to realize an advertising device using an air flow inflation balloon that prevents dust and sand dust from being sucked into a balloon and clogging of a filter for preventing the dust even when used outdoors. It is in.

  Another object of the present invention is to realize an advertising device using an air flow inflation balloon that does not cause malfunction or stop of the rotation of the balloon over a long period of time even if the outdoor use is continued and repeated.

Means for solving the problem

  In order to achieve the above object, an advertising device according to the present invention includes a balloon made of a light-transmitting and flexible film having a light-transmitting advertising message on at least one of the front surface, the back surface, and the surface, and an opening of the balloon. An advertising device comprising a base for rotatably supporting, a light source for providing a light source for illuminating the balloon from the inside, and a blower for supplying an air flow for inflating the balloon. The balloon comprises a fixed portion that does not rotate during use, a rotating portion that is rotatably supported by the fixing portion, and a driving means for rotating the rotating portion, and the balloon opening is hermetically fixed to the rotating portion. The inside of the balloon is separated from the fixed part by the rotating part, the blower and the driving means are supported by the fixed part, and the rotating part surrounds the upper part and the side surface of the fixing part to form a space in the corresponding part of the base part In this space, the blower and the driving means are accommodated, the light source part is composed of a light source and a light source support part, the light source is located in the balloon, the light source support part is supported by the fixed part, and the rotation part is sent from the blower to the balloon. It has the penetration part which allows air current to pass in.

  The advertising device of the present invention having such a feature includes a rotating part, an annular disk part having an opening near the center, an outer cylindrical part having one end fixed to the outer periphery of the annular disk part, and an annular disk part. An inner cylindrical part having one end fixed to the inner periphery of the inner part, the annular disk part is located on the upper part of the fixed part, and the outer cylindrical part is located on the side surface of the fixed part. The upper and side surfaces are formed so as to be surrounded by the rotating part, and the balloon opening is fixed near the outer periphery of the annular disk part. Airflow is supplied to the inside of the balloon from a blower located in a space surrounded by the rotating part and supported by the fixed part via the inner cylindrical part of the rotating part and the opening of the annular disk part. .

  According to this structure, the driving means for rotating the rotating portion is provided in the fixed portion, the driving means and the inner cylindrical portion of the rotating portion are connected by the belt, and the entire rotating portion is rotated by the driving means via the belt. It is possible to easily rotate the balloon fixed to the part.

  The drive means is composed of a pulley for turning the belt, a clutch for transmitting rotational force to the pulley, and a motor connected to the input side of the clutch, and the clutch exceeds a predetermined load. Sometimes, it is useful to prevent the failure of the device if a device that stops transmission of rotational force is used. Such a clutch is, for example, a friction clutch that slips when a predetermined load is exceeded.

  The fixing portion may be provided with a section having an opening connected to the side surface of the inner cylindrical portion or an end portion far from the annular disk portion and leading to the inner cylindrical portion. Since the blower is disposed outside the compartment, the compartment is provided with a second opening connected to the exhaust port of the blower. In this case, the air flow path (the “penetrating portion” in claim 1) is formed by this section, the inside of the inner cylindrical portion, and the opening of the annular disk portion.

  The light source unit usually includes a light source for illuminating the balloon from the inside and a light source support unit for coupling and supporting the balloon to a fixed part of the base. Since the light source needs to be located inside the balloon, the light source support part penetrates the inner cylindrical part of the rotating part, but it is preferable that the main part of the light source support part is located in the inner cylindrical part. When the main part of the light source support part is located in the inner cylindrical part, the remaining part penetrates the opening of the annular disk part and slightly protrudes toward the inside of the balloon. In order to avoid the loss of light and to dissipate heat from the light source, it is preferable that the entire light source is located outside the inner cylindrical portion.

  A blower located in the fixed portion can be directly connected to the inner cylindrical portion, and airflow can be supplied to the balloon through the opening of the annular disk portion. It is also possible to provide another annular part in the annular disk part in addition to the opening part near the center, and supply airflow to the balloon therethrough.

  Although it is possible to provide the fixed part with a cylindrical part (fixed) so that it overlaps the inside of the outer cylindrical part of the rotating part, the weight of the fixed part becomes heavy and the maintenance work of the fixed part is difficult. The side surface of the base is preferably composed only of the outer cylindrical part of the rotating part.

  In the airflow inflation balloon type advertising device of the present invention, since a space independent from the inside of the balloon is formed in the base portion, an air inlet of the blower can be provided therein, and the air blower passes through the inside of the base portion. And can take in air. If the air inlet of the blower in the base is provided in a direction parallel to the bottom surface of the base, even if outside air is taken in from the lower part of the fixed part, dust and water droplets are hardly sucked.

  In order to prevent dust and water droplets from being sucked into the balloon, it is preferable to provide a filtering member at the air inlet of the blower. A filtering member comprising at least two perforated cylinders having different diameters and arranged so that the positions of the holes are shifted from each other is particularly preferable because it is free from clogging by water droplets and has an excellent effect of removing dust and water droplets. The end of the filtration member on the side opposite to the intake port may be closed, or may be constituted by two or more perforated plates whose positions of the holes are shifted from each other.

  The base may be provided with a reflecting mirror for converging the light beam from the light source toward the balloon on the light source support part or the rotating disk part. When provided in the light source support part, the reflecting mirror is fixed, but when provided in the rotating disk part, the reflecting mirror rotates together with the rotating part. This reflector is provided with a window through which a part of the light beam traveling in the direction opposite to the balloon is passed, and a light reflecting member is provided at a position facing the reflector window of the base portion (for example, the upper surface of the annular disk portion). The light beam that has passed through may be reflected and directed toward the balloon, resulting in a more even illumination throughout the balloon. It is advantageous to provide two or more reflector windows symmetrically. The window may be a hole that penetrates the reflecting mirror, or may be a window that does not penetrate but is made of a light-transmitting material.

  You may provide the light reflection member which reflects the light beam which passed the inside of a balloon toward a balloon again in the terminal part far from the base part of a balloon. The light reflecting member may be provided inside the end portion of the balloon, or may be provided outside if the tip of the balloon is transparent.

  The light source unit and the blower may be fixed to the fixed unit, or may be slightly moved, for example, adjusted in position as necessary.

  The balloon can have various shapes such as a spherical shape, a hemispherical shape, a cylindrical shape, and a conical shape, but the opening is preferably a circle. The part far from the base part may extend from the opening part, and can also have an arbitrary three-dimensional shape such as a human image, an animal image, a fruit, a flower, a tree, or a vehicle.

  The coupling portion between the balloon and the rotating portion is configured to sufficiently prevent the leakage of the airflow. It is convenient for handling if the coupling part is detachable. As a coupling means, a known one, for example, a magic fastener may be used.

  The balloon coating is usually translucent, but may be partially transparent. For example, a polyester cloth is suitable as the material of the film. The film may be a single layer or a multilayer.

  A part of the balloon may be transparent, and a luminous body or a moving body that moves in a complicated manner may be present inside the balloon so that they can be seen through the transparent part. The complex motion of the moving body may be regular or irregular.

  The light emitter is, for example, an LCD or an EL wire. The luminous body may perform regular movement such as rotation, or may perform complicated movement such as rotation and revolution, or linear movement while rotating. The phosphor may be a phosphor. In this case, a light source for excitation may be provided in the balloon or in the base portion, but ultraviolet light from the outside may be used for excitation of the phosphor.

  The moving body that moves in a complicated manner is preferably a floating body that floats by an air current. As this airflow, an airflow for inflating the balloon may be used as it is, but an airflow different from the airflow for inflating the balloon can also be used.

  The advertisement message is provided on any one or more of the outer surface, the inner surface, and the surface of the coating. In the case where the advertisement message is provided on the surface of the film, it can be easily exchanged as necessary if the portion is detachable from the film.

  Since the planar shape of the fixed part of the base part is surrounded by the rotating part, a circle is preferable. You may provide a penetration part in a bottom face as needed so that external air can be supplied to the inlet of a blower. You may enable it to supply external air from the penetration part provided in the outer side cylindrical part of the rotation part. In the vicinity of the penetrating portion, a means such as a filter for preventing intrusion of dust and water droplets may be provided. The fixing unit may be rotated (for example, provided with a caster) if necessary when the advertising device is not used.

(Operation of the advertising device of the present invention)
When the blower provided at the base is operated, the airflow is sent from the blower arranged in the space surrounded by the rotating part inside the base to the inside of the balloon through the penetrating part. Will inflate the balloon with the advertising message. When the light source is turned on, the advertising message provided on the light-transmitting balloon is illuminated with a uniform brightness by the light beam directly from the light source and from the reflector or reflecting member. The function of the advertisement is demonstrated. The balloon rotates with the rotation of the rotating part, and draws the attention of people passing by, so the advertising effect is high. When the advertisement is unnecessary, the light source is turned off, the rotation of the balloon and the blower are stopped, the balloon is deflated, the volume is reduced, and it is stored in an appropriate place.

The invention's effect

  In the air-balloon balloon type advertising device of the present invention, the base portion that rotatably supports the balloon opening portion includes a fixed portion that does not rotate during use of the device, and a rotating portion that supports and rotates the balloon opening portion. Because the balloon and the rotating part that surrounds the fixed part are configured to rotate together, the center of gravity of the entire rotating part including the balloon is low, and therefore stable even when the balloon receives a crosswind. It is.

  In addition, since the balloon and the side wall of the rotating part continuously form the side surface of the device, and there is no connecting part for allowing rotation between the rotating balloon and the side surface of the fixed part, it is possible to prevent wind and rain from the side. Even if it is received, rainwater will not enter the fixed part.

  In the airflow inflation balloon type advertising device of the present invention, since the fixed portion has a space independent from the inside of the balloon, the air inlet of the blower can be provided in this space. As in the past (for example, Patent Document 2), when the air blower is arranged in a common space with the inside of the balloon, there is no choice but to take in air from the outside of the fixed portion, so that dust and moisture easily enter the air blower. However, in the apparatus of the present invention, air can be taken into the blower within the fixed portion, so that the suction of dust and water droplets can be reduced.

  In a preferred advertising device according to the present invention (Claim 4), the rotating part is composed of an annular disk part, an inner cylindrical part and an outer cylindrical part, and further, a section connected to the inner cylindrical part is provided in a part of the fixed part. The airflow from the blower to the balloon can be supplied through this section and the inner cylindrical portion.

  According to the structure of the preferred advertising device of the present invention (Claim 2), the inner cylindrical portion is connected to a driving portion (for example, a motor and a pulley) supported by the fixed portion by a belt, and the rotating portion is rotated to rotate. The balloon fixed to the outer periphery of the disk part can be rotated. In such a device (Claim 9), since the driving part (motor, etc.) is connected to the rotating part for rotating the balloon by the belt, the displacement is absorbed by the belt even if the balloon is slightly inclined due to the cross wind. In addition, a strong external force is not applied to the drive unit and other rotation mechanisms. Even if a slightly heavy load is generated by an external force, there is a mechanism (such as a friction clutch) that avoids it between the drive unit and the belt, so that the rotation-related parts can be avoided by simply stopping the rotation. .

  FIG. 4 shows details of the rotation drive unit 17. The rotation drive unit 17 includes a motor 31, a driving rotation shaft 32 rotated by the motor 31, a friction clutch 33 connected to the shaft, and a pulley 34 for turning the belt 22B. The friction clutch 33 has a clutch plate 33 a that is pressed against the side surface of the pulley 34. The pulley 34 can freely rotate around the driving rotary shaft 32, and the driving rotary shaft 32 transmits a rotational force to the pulley 34 via the clutch plate 33 a of the friction clutch 33.

  FIG. 5 shows an axial cross section of the filter 15b. The filter 15b includes two porous cylinders 41 and 42 having different diameters, and the positions of the holes are arranged so as to be shifted from each other. One end of the cylinder is fitted into the air inlet 15a of the blower fan 15, and the other end is closed.

(Operation of the first embodiment)
(Balloon inflation)
When the blower fan 15 provided in the base portion 1 is operated, the air in the space L is taken into the intake port 15a of the blower fan 15 through the filter 15b, and the airflow is formed in the through portion 13 provided on the side wall of the partition 12. The balloon 2 with the advertising image sheet 3 is inflated by being supplied to the space U inside the balloon through the inner cylindrical portion 22 and the central opening of the annular disk portion 21.

(Balloon lighting)
The balloon illumination will be described with reference to FIG. When the light source 14L is turned on, the balloon 2 is illuminated from the inside by direct and indirect light from the light source 14L. The intermediate part 2b of the balloon 2 is illuminated mainly by the light beam directly reflected from the light source 14L and reflected by the reflecting mirror 24. Since most of the light beam traveling in the direction opposite to the balloon 2 is converged toward the balloon 2 by the reflecting mirror 24, the entire circumference is illuminated brightly from the light source 14L to the upper portion 2c of the balloon. A part of the light beam traveling in the opposite direction to the balloon 2 passes through the window 24W, is reflected by the reflecting plate 21R provided on the upper surface of the annular disk portion 21, and travels around the reflecting mirror 24 and the like toward the balloon 2. This reflected light supplements the illuminance of the lower portion 2a of the balloon 2 with little reflected light from the reflecting mirror 24. The advertisement image sheet 3 affixed to the side surface of the balloon 2 is illuminated through the light-transmitting balloon 2, and the advertisement function is exhibited even at night or in a dark place.

(Balloon rotation)
When electric power is supplied to the motor 31 of the rotation drive unit 17 before, after or simultaneously with the lighting of the light source 14L, the driving rotation shaft 32 rotates, and the rotational force is transmitted to the pulley 31 via the friction clutch 33, and the pulley 31 rotates. The belt 22B rotates around the shaft 32, and the inner cylindrical portion 22 connected to the belt 22B rotates. Since the annular disk portion 21 rotates together with the inner cylindrical portion 22, the balloon 2 having the opening 2A fixed on the outer periphery thereof rotates.

(Balloon storage)
When it is not necessary to use the device, the light source 14L is turned off, the motor 31 is stopped and the balloon 2 stops rotating, and then the blower fan 15 is stopped and the balloon 2 is contracted to reduce the volume of the device. Can be stored in a suitable place.

(Effects of the first embodiment)
Since the rotating part 1B is composed of the annular disk part 21, the inner cylindrical part 22, and the outer cylindrical part 23, the blower fan 15 and the rotational driving part 17 are installed in the bottom part 11 in the space L covered by them. A fixed part is accommodated. On the other hand, the opening 2A of the balloon 2 is airtightly fixed to the outer periphery of the annular disk part 21, and the annular disk part 21, the inner cylindrical part 22, the partition 12, and the bottom part 11 of the fixing part are continuous. A space U including the inside of the balloon 2 is formed. The airflow to the balloon 2 is supplied from the blower fan 15 provided in the space L to the space U through the penetration part 13 provided in the section 12. That is, the airflow to the balloon 2 is supplied from the air inlet 15 a of the blower fan 15 provided in the space L through the blower fan 15, the through portion 13, the partition 12, and the inner cylindrical portion 22. The blower fan 15 takes in air from the space L in the fixed portion 1A, not from the outside of the base portion 1 in parallel to the bottom surface of the base portion, so that it is easy to prevent dust and water droplets from entering the air.

  Further, according to the above configuration of the advertising device, the inner cylindrical portion 22 and the rotation driving portion 17 supported by the fixed portion 1A are connected by the belt 22B, and the entire rotating portion 1B is rotated, so that the outer circumference of the annular disk portion 21 is increased. The balloon 2 fixed to can be rotated. Since the drive unit 17 and the balloon 2 are connected via the belt 22B, even if the balloon 2 is slightly inclined due to a crosswind, the inclination is absorbed by the belt 22B, and a strong external force is not applied to the rotation mechanism such as the drive unit. . Even if a slightly strong load is generated by an external force, the friction clutch 33 is interposed between the motor 31 and the belt 22B. Therefore, the rotation is temporarily stopped, and damage to the parts can be avoided.

  Further, the balloon 2 and the outer cylindrical part 23 of the rotating part form a side surface of the entire apparatus. When a cross wind is received, an external force of the wind is applied to both of them, and the force for inclining the balloon 2 is It is reduced than when not. Further, the structure in which the balloon 2 and the rotating part 1B are integrated has a relatively low center of gravity, and the moment applied to the connecting part with the fixed part is reduced, so that damage to the connecting part is reduced.
