Description

  The present invention relates to a light-emitting balloon that is filled with a gas and can float in the air.

  Conventionally, there are balloons filled with helium gas that is lighter than air and floating in the atmosphere. In recent years, an attempt has been made to attach a light source inside the balloon and cause the balloon itself to emit light. In this type of light-emitting balloon, a method has been proposed in which both the battery and the light-emitting source are accommodated in the balloon body and the periphery is completely welded (see, for example, Patent Document 1).

  In addition, a method has been proposed in which an opening is formed in the balloon body, a lighting device is attached to the opening in an airtight state, and a light source is arranged in the balloon (see, for example, Patent Document 2).

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 to 4 show a light-emitting balloon 1 according to an embodiment of the present invention. The light emitting balloon 1 includes a balloon body 5 and a light source device 30. The balloon body 5 is filled with a medium having a specific gravity lighter than air, such as helium gas, so that buoyancy can be obtained.

  The balloon body 5 is configured by superimposing a first sheet 10 having light transmission characteristics and a second sheet 20 having light reflection characteristics at least on the inner side, and thermally welding or bonding the peripheral edges 25 to each other. Although not particularly illustrated here, a filling port for filling gas is formed in the peripheral edge 25, and the filling port can be sealed by thermal welding after filling.

  FIG. 5 shows an enlarged detailed laminated structure of the first sheet 10 and the second sheet 20. The first sheet 10 includes a first sheet layer 12 and a coating layer 18. The first sheet layer 12 includes a polymer film 13 made of a polypropylene film or a polyethylene film, a polyamide resin film 14 such as nylon, and an EVOH film 15 made of a copolymer of vinyl alcohol and ethylene. Composed. A coating layer 18 is laminated on the EVHO film 15 side. Specifically, the coating layer 18 is formed by printing a white paint in the present embodiment. The coating layer 18 constitutes a light diffusion region in the present invention, and when the coating layer 18 is in a translucent state, light is irregularly reflected on the white paint, and the entire first sheet 10 can be lit white. In addition, although the case where the light diffusion region is configured by the coating layer 18 made of white paint is shown here, other than that, for example, ultrafine beads or the like are applied to the first sheet layer 12 or the first sheet layer 12 A light diffusion region for irregularly reflecting light may be formed by forming irregularities on the surface itself.

  The second sheet 20 includes a second sheet layer 22 and a light reflecting layer 28. The second sheet layer 22 is formed by laminating a polymer film 23 made of a polypropylene film or a polyethylene film, a polyamide resin film 24 such as nylon, and an EVOH film 25 made of a copolymer of vinyl alcohol and ethylene. Composed. A light reflecting layer 28 is laminated on the EVHO film 25 side. Specifically, the light reflecting layer 28 is formed by vapor-depositing a metal material (here, aluminum) on the second sheet layer 22. As a result, light transmitted through the second sheet layer 22 from the inside of the balloon body 10 is reflected by the light reflecting layer 28. The first sheet 10 and the second sheet are welded so that the polymer films 13 and 23 face each other.

  By making the first and second sheets 10 and 20 into a laminated structure of a plurality of materials, for example, in the polymer films 13 and 23, the confidentiality of the balloon is improved by mutual welding, and in the polyamide resin films 14 and 24, The mechanical strength of the balloon is ensured, and the EVOH films 15 and 25 prevent the filling gas from oozing out due to the gas barrier characteristics. As a result, it is possible to configure the balloon main body 5 that is extremely light and functional.

  As shown in FIG. 1 and FIG. 6, the light source device 30 includes three LED light sources 34 disposed substantially at the center of the outside of the first sheet 10 and a base that integrally couples the three LED light sources 34. A stand 36, a holder 40, a wiring 60 for supplying electricity to the LED light source 34, and a power source 70 connected to the lower end of the wiring 60 are provided.

  The power source 70 incorporates a battery and turns on / off the supply of electricity to the LED light source 34 by a switch (not shown). The wiring 60 also serves as a string that connects the power supply 70 and the balloon main body 5, and prevents the balloon main body 5 from flying away due to the weight of the power supply 70.

  Referring to FIG. 6, the holder 40 has a hollow inverted conical shape having no bottom surface, and an insertion port 42 is formed by cutting out the apex located on the lower end side, and the upper end side is an open end 43. It has become. In the holder 40, the LED light source 34 and the base 36 are accommodated, and the wiring 60 is inserted into the insertion opening 42. By making the size of the insertion opening 42 smaller than the LED light source 34 or the base 36, the LED light source 34 or the base 36 is prevented from dropping from the holder 40. In other words, the vicinity (periphery) of the insertion opening 42 in the holder 40 becomes the holding portion 44, and the LED light source 34 and the base 36 are held by the holding portion 44.

  At the open end 43 (the bottom side of the cone) of the holder 40, four coupling portions 46 are formed in the circumferential direction. The coupling portion 46 is formed with a flat surface facing the balloon body 5 and is coupled to the balloon body 5 by an adhesive material 46A such as a double-sided tape. Therefore, the holder 40 is mounted on the outside of the first sheet 10 with the LED light source 34 accommodated therein.

  Furthermore, the holder 40 includes a light reflecting portion 48 using the inner peripheral side surface thereof. The light reflecting portion 48 is made of an aluminum foil or the like having light reflecting characteristics, covers the periphery of the LED light source 34, and reflects the light from the LED light source 34 toward the first sheet 10. As a result, all the light emitted from the LED light source 34 is irradiated into the first sheet 10.

  On the other hand, the vicinity of the LED light source 34 in the first sheet 10, specifically, the inner region of the open end 43 of the holder 40 is a transparent region 19. In addition, this transparent area | region 19 is made into the colorless and transparent state of only the 1st sheet layer 12 by not forming the coating layer 18 mentioned above. As a result, the light from the LED light source 34 passes through the transparent region 19 and is irradiated on the inner surface of the second sheet 20.

  According to the light-emitting balloon 1 of the present embodiment, the balloon body 5 is constituted by the first sheet 10 having light transmission characteristics and the second sheet 20 having light reflection characteristics. All light can be emitted to the outside from the first sheet 10 side. Accordingly, since the light is not dispersed and emitted in multiple directions, the first sheet 10 can be extremely brightened.

  In particular, since the reflection efficiency is enhanced by vapor-depositing a metal material such as aluminum on the second sheet 20 side, the first sheet 10 side can be made extremely bright.

  Further, in the present light-emitting balloon 1, since the coating film 18 is formed in a translucent state by using a white paint on the first sheet 10, the first sheet 10 itself becomes a light diffusion region. Therefore, as shown in FIG. 6, when the light reflected by the second sheet 20 reaches the first sheet 10, it is irregularly reflected by the coating film 18 (light diffusion region), so that the entire first sheet 10 is white. An atmosphere that emits light can be created.

  Further, in the light emitting balloon 1, the light source device 30 is fixed to the approximate center of the outer peripheral side of the first sheet 10 in the balloon main body 5 with an adhesive. As a result, it is not necessary to form an opening for installing the light source in the balloon main body 5 while sufficiently securing the brightness of the first sheet 10. Therefore, it is possible to increase the confidentiality of the balloon body 5 and, according to the experiments by the present inventors, it is possible to secure a floating time of, for example, one week or more. Moreover, since the special welding process in the balloon main-body part 5 becomes unnecessary, manufacturing cost can also be reduced and it becomes possible to raise commercial value. Similarly, the balloon main body 5 and the light source device 30 can be kept separate during transportation, and in use, the balloon main body 5 is inflated and then the preparation is completed simply by fixing the light source device 30 with a double-sided adhesive. Therefore, it is possible to improve the workability outdoors.

  Further, the holder 40 of the light source device 30 covers the periphery of the LED light source 34 by the light reflecting portion 48 and reflects the light to the first sheet 10 side. A colorless transparent region 19 is formed on the first sheet 10, and the light from the external LED light source 34 is efficiently taken into the inside. As a result, substantially all of the light from the LED light source 34 disposed in the center of the first sheet 10 is reflected by the light reflecting portion 48 and passes through the transparent region 19 and is irradiated on the inner surface of the second sheet 20. . By reflecting light by the second sheet 20, it is possible to make the first sheet 10 shine brighter in a ring state.

  In particular, in the present embodiment, a gripping string (wiring 60) is suspended from the light source device 30 fixed to the center of the first sheet 10. As a result, the bright first sheet 10 side can be floated in a state where the user faces the user, that is, the posture in which the second sheet 20 in the balloon body 5 is on the upper side and the first sheet 10 is on the lower side.

  In the present embodiment, only the case where a white paint is used in the first sheet 10 is shown. However, in addition to white, printing may be performed using a paint such as yellow, light blue, or pink. In addition, this light diffusion region is not necessarily limited to being translucent or formed with a paint such as white, and is configured by using another light diffusion material or a light diffusion material, or using a fluorescent paint. It is also possible. Furthermore, this light diffusion region does not need to be formed on the entire first sheet 10, and may be formed in a specific region such as a design. These points are the same for the light reflecting layer of the second sheet 20. Furthermore, in the present embodiment, the holder 40 has an inverted conical shape, but the present invention is not limited to this, and may have a triangular pyramid shape or a cylindrical shape. Similarly, in the holder 40, only the case where the coupling portion 46 and the holding portion 44 are integrally formed is shown. However, the present invention is not limited to this, and the coupling portion and the holding portion may be configured as separate members. Is possible.

  Further, in the present embodiment, the second sheet 20 in the balloon body 5 is shown in the upper side and the first sheet 10 is floated in a horizontal posture that is the lower side, but the present invention is not limited to this, For example, as shown in FIG. 7, by attaching the light source device 30 in the vicinity of the periphery of the first sheet 10, the balloon body 50 can be floated in a vertical posture. Similarly, as shown in FIG. 8, the light source device 30 is attached to the vicinity of the center of the first sheet 10, and the string (wiring) side is fixed to the peripheral edge of the balloon main body 5, so that the balloon main body 50 is vertical. It is also possible to float in a posture.

  Furthermore, in the present embodiment, only the case where the light source is fixed to the outside of the balloon body is shown, but it is also possible to arrange the light source inside the balloon body. Even in this case, it is preferable to emit the light from the light source to the second sheet 20 side to shine the entire first sheet using the reflected light.

  Further, in the present embodiment, the sheet material of the balloon main body is shown only in the case of a multilayer structure with a plurality of materials, but the present invention is not limited to these specific materials, and various materials can be used according to the purpose. Can be used. For example, rubber or the like can be used.

  Note that the light-emitting balloon of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
