Description

  The present invention relates to an electric signboard, and more particularly, to an electric signboard that illuminates advertisement information drawn on a light-transmittable inflatable bag body from behind (inside).

  BACKGROUND ART An electric signboard that illuminates advertisement information drawn on a light-transmittable inflatable bag with a light emitter from the back (inside) thereof has been conventionally known (see, for example, Patent Document 1). That is, according to this electric signboard, the advertising information drawn on the bag is arranged inside the bag and illuminated from behind (inside) the light emitter.

Japanese Utility Model Publication No. 63-165686

  However, in the conventional electric signboard as described above, the advertising information drawn on the bag is illuminated from behind (inside) by the light emitter disposed inside the bag. The light-emitting body that can be used is limited to a small and simple structure that can be easily inserted into and removed from the inside of the bag body, such as an optical fiber tip described in the same document. Therefore, if it is intended to illuminate the circumferential surface of the bag uniformly, it is necessary to further diffuse the light from the tip of the optical fiber, which is a light emitter, with a lens, and to secure a sufficient amount of light necessary for illumination. As a result, it can hardly be put to practical use as an electric signboard.

  The present invention has been made paying attention to the above-mentioned problems, and the object of the present invention is to provide a sufficient amount of advertising information drawn on the bag without housing the light emitter inside the bag. It is to provide an electric signboard that can be illuminated from behind (inside) and that is simple in structure and inexpensive to manufacture.

  Other objects and operational effects of the present invention will be easily understood by those skilled in the art by referring to the following description of the specification.

  The above technical problem is solved by an electrical signboard having the following configuration, a bag for an electrical signboard, a light emitter for the electrical signboard, and a method for manufacturing the electrical signboard.

  That is, the electric signboard according to the present invention is a light-permeable airtight bag body using a resin sheet in which advertising information is drawn, and when a predetermined amount of pressurized air is injected, expands to a predetermined completed form, A straight rod-shaped light emitter that is outside the bag body and also serves as a support. The bag is formed so as to surround the periphery of the bag leaving a tunnel-like space for receiving the straight rod-like light emitter. The inner diameter of the tunnel-shaped space is sufficiently larger than the outer diameter of the straight rod-shaped light emitter when the bag body is not yet expanded before the pressurized air is injected, and the bag is formed by the pressurized air injection. In a state where the body has expanded to the completed shape, it is structured to have a diameter sufficiently smaller than the outer diameter of the straight rod-shaped light emitter.

  According to such a configuration, when the straight rod-shaped light emitter is inserted into the tunnel-shaped cavity, pressure is injected into the bag body and the bag body is inflated to a predetermined completed form. When the inner diameter is narrowed and tightened from the inner wall, the straight rod-like light emitter is firmly fixed (gripped) in the tunnel-like cavity. At this time, since the straight rod-shaped light emitter also serves as a support, the bag can be supported on, for example, a horizontal floor or a vertical wall via the straight rod-shaped light emitter. On the other hand, at this time, although the straight rod-shaped light emitter is located outside the bag body, the tunnel-shaped cavity is in a position surrounded by the bag body, so that the light emitted from the straight rod-shaped light emitter passes through the tunnel-shaped void. The advertising information drawn on the bag is illuminated from behind (inside) through the surrounding resin sheet. On the other hand, if the air pressure filled in the bag body is released by opening the plug, the inner diameter of the tunnel-shaped cavity expands. Therefore, by simply pulling out the straight bar-shaped light emitter from the tunnel-shaped cavity, The bag body can be updated by a simple operation. Therefore, it is possible to illuminate the advertising information drawn on the bag body with a sufficient amount of light without accommodating a light emitter inside the bag body, and the structure is simple and inexpensive to produce. Signs can be provided.

  In a preferred embodiment, the resin sheet forming the tunnel-shaped space may be provided with heat resistance for avoiding thermal fusion with the straight rod-shaped light emitter.

  According to such a configuration, the resin sheet forming the tunnel-like void is fused with the straight rod-shaped light emitter and cannot be pulled out by heat generated from the straight rod-shaped light emitter, and the dismantling of the electric signboard or the renewal of the bag body Can be prevented in advance.

  In a preferred embodiment, the resin sheet forming the tunnel-shaped void may be provided with optical filter characteristics for adjusting the light amount and wavelength range of light emitted from the straight rod-shaped light emitter. .

  According to such a configuration, by appropriately adjusting the optical characteristics of the resin sheet that forms the tunnel-shaped void, the bag body can be obtained without changing the light amount or wavelength range of light emitted from the straight rod-shaped light emitter. It is possible to adjust the amount of light and the wavelength range for illuminating the advertising information drawn in the above, and it is possible to obtain more design freedom.

  In a preferred embodiment, the bag body has a plurality of independent and flat sheet pieces formed by developing the resin sheet constituting the bag body in each element portion, and a plurality of independent flat sheet pieces that are adjacent to each other are welded. It may be formed by connecting them through.

  According to such a structure, the bag body which has arbitrary three-dimensional shapes and arbitrary advertising information was drawn can be manufactured easily.

  According to a preferred embodiment, the straight rod-shaped light emitter includes a transparent straight rod-shaped tube and a plurality of lamps disposed in the straight rod-shaped tube at appropriate intervals in the longitudinal direction thereof. You may do.

  According to such a configuration, it is possible to manufacture a straight rod-shaped light emitter having an arbitrary length by using a plurality of lamps arranged in series, while maintaining the function as a support by a transparent straight rod-shaped tube.

  The present invention viewed from another aspect can also be grasped as a bag constituting the electric signboard having the above-described configuration.

  The present invention viewed from another aspect can also be understood as a straight bar-shaped light emitter that constitutes an electric signboard having the above-described configuration.

  The present invention viewed from another aspect can be grasped as a method of manufacturing an electric signboard. That is, in this method, a step of preparing a plurality of independent and flat sheet pieces formed by developing a resin sheet constituting the bag body on each element portion, and a plurality of the sheet pieces to be arranged adjacent to each other A step of completing the bag body by connecting each other via a welding line, and a step of inserting a straight rod-like light emitter into the tunnel-like space of the bag body in a state where no pressurized air is injected or sufficiently injected And by injecting pressure into the bag body in which a straight bar-like light-emitting body is inserted into the tunnel-shaped space, inflating the bag body to the predetermined completed form, and then closing the bag. And a step of closely contacting the hollow space and the straight rod-shaped light emitter.

  According to such a configuration, it is possible to easily and inexpensively manufacture an electric signboard that includes a bag body having an arbitrary three-dimensional shape and can brightly illuminate advertisement information drawn on the bag body.

  In the electric signboard described above, if the cross-sectional shape of the straight bar-shaped light emitter and the cross-sectional shape of the tunnel-shaped space are both circular, the affinity between the straight-bar light emitter and the tunnel-shaped space is good. Thus, the straight rod-shaped illuminant is stably held in the tunnel-shaped cavity, and at the same time, the light emitted from the straight rod-shaped illuminant is more uniformly dispersed in the bag.

  Further, if one end of the straight rod-shaped light emitter is provided with a fixture that can be attached in a vertical posture to a flat support surface such as a floor surface or a wall surface, a bag on which advertisement information is drawn The body can be mounted perpendicular to the floor or wall via a straight rod-like light emitter.

  In addition, if the straight bar-shaped light emitter is mounted in a vertical posture on a carriage that can move on the floor surface, the vertical body is maintained in the vertical posture through the straight bar-shaped light emitter. You can move on the floor or on the road.

  Further, the plurality of lamps are light emitting diode lamps, and can be emitted in two directions different by 180 degrees if they are arranged on both surfaces of an elongated support plate inserted and fixed along the longitudinal direction in the straight rod-shaped tube. The diffused light can be widely dispersed.

  According to the present invention, it is possible to illuminate advertisement information drawn on a bag body with a sufficient amount of light without accommodating a light emitter inside the bag body, and it is possible to manufacture the structure simply and inexpensively. You can provide a signboard for your lighting.

[1. First Embodiment]
[1.1 Overall structure of the signboard]
First, the whole structure of the electrical signboard 1 is demonstrated, referring FIG.1 and FIG.2.

  FIG. 1 is an external perspective view showing an example of an electric signboard 1. As is clear from the figure, the electric signboard 1 has a straight rod-shaped light emitter 30 that also serves as a support, and a substantially cylindrical tip that surrounds the upper end portion of the straight rod-shaped light emitter 30 by being inflated by injecting pressure. It is comprised from the part bag body 10 and the substantially cylindrical peripheral side part bag body 20 which inject | pours pressure air and expands and surrounds so that the surrounding side surface of the straight rod-shaped light-emitting body 30 may be clamped. The peripheral side bag body 20 may have an annular horizontal cross section, and the outer diameter may be about 500 mm, for example, and the height may be about 800 mm, for example.

  The tip end bag 10 and the peripheral side bag 20 are both made of polyurethane. Therefore, not only is it excellent in durability and weather resistance, but even when the straight rod-shaped light emitter 30 is heated by the light emission, thermal fusion or the like hardly occurs on the contact surface, and there is less possibility that it cannot be pulled out. . Moreover, the front-end | tip part bag body 10 and the peripheral side part bag body 20 are light-transmitting, the advertisement and promotion information are printed on the surface, and also it is illuminated from the inner side by the straight rod-shaped light-emitting body 30 of center part. . Therefore, it is possible to realize the electric signboard 1 that is easy to visually recognize even in the dark or from a distance. Further, since the straight bar-shaped light emitter 30 is left unchanged and only the tip end bag 10 and the peripheral side bag 20 are replaced, new advertisement / promotion can be performed, so that it is easy and inexpensive. Various advertisements and promotions can be performed. In addition, although this kind of signboard is frequently changed in advertising content (for example, every three months) depending on the application, only the tip end bag body 10 and the peripheral side bag body 20 are replaced or disposable, Low-cost operation is possible.

  With reference to the exploded perspective view of the electric signboard 1 shown in FIG. 2, the details of assembling the tip end bag body 10, the peripheral side bag body 20, and the straight rod-shaped light emitter 30 will be described.

  The straight rod-shaped light emitter 30 has a light emitting element assembly 307 disposed in the center thereof and a circular section 302 that transmits light from the light emitting element assembly 307, and a cylindrical body 302 disposed at the lower end of the cylindrical body 302. A circular flange-shaped fixture 303 that is vertically supported and a tip protection member 301 having a circular cross section that protects the tip of the upper end side of the cylindrical body 302 are configured. The light emitting element assembly 307 is connected to an external power source (not shown) through a power line 304. Further, the diameter of the cylindrical body 302 is D4, the diameter of the tip protection member 301 is D3, and the diameter of the small diameter cylindrical portion of the fixture 303 is D5. As will be described later, the distal end bag body 10 and the peripheral side bag body 20 are fixed to the straight bar light emitter 30 so as to tighten the straight bar light emitter 30.

  At the center of the bottom surface 102 of the tip end bag body 10, a circular tip end bag body opening portion 103 having a diameter D6 having a large number of radial closing pieces at the entrance is provided, and vertically upward from the tip end bag body opening portion 103. A distal end bag body tunnel-like cavity 101 that extends toward and does not penetrate is provided. The inner wall of the distal end bag body tunnel-like cavity 101 is overhanged by pressurized air injection to have a small diameter, and becomes the smallest diameter D7 in the vicinity of the middle abdomen. At this time, the diameter D6 is sufficiently larger than the diameter D3 of the tip protection member 301 of the straight rod-shaped light emitter 30 or the diameter D4 of the cylindrical body 302, but the diameter D7 is the diameter of the tip protection member 301 of the straight rod-shaped light emitter 30. It is sufficiently smaller than D3 or the diameter D4 of the cylinder 302.

  According to such a configuration, in a state where the upper end portion of the straight light emitter 30 is inserted into the distal end bag body tunnel-like space 101, pressurized air is injected into the distal end portion bag body 10 to When inflated to a predetermined completed form, the inner diameter of the tunnel portion 101 at the tip end portion is narrowed and tightened from the inner wall, whereby the straight bar-shaped light emitter 30 is firmly fixed (gripped) in the space. Further, if the pressure filled in the tip end bag 10 is released, the inner diameter of the tip end bag body tunnel-like cavity 101 increases, so that the straight bar-like light emitter 30 can be easily pulled out of the cavity. It is also possible to dismantle the signboard 1 and update the tip end bag body 10 with a simple operation.

  Further, at the center of the top surface 202 on the substantially elliptical shape of the peripheral side bag body 20, a circular top surface side opening 203 having a diameter D1 and having a large number of radial closing pieces at the entrance is provided on the peripheral side bag body. A circular bottom surface side opening 206 having a diameter D1 having a large number of radial closing pieces at the entrance is provided at the center of the approximately elliptical bottom surface 205, and the top surface side opening portion 203, the bottom surface side opening portion 206, and Between them, a circumferential side bag body tunnel-like void 201 is provided to connect them. That is, the peripheral side bag body 20 has a peripheral side surface 204 on which advertisements and promotions are printed, and an inner peripheral surface constituting the peripheral side bag body tunnel-like space 201. The peripheral side bag body tunnel-like void 201 has a small diameter with the inner peripheral wall projecting out by pressurized air injection, and has the smallest diameter D2 in the vicinity of the middle abdomen. At this time, although the diameter D1 is sufficiently larger than the diameter D3 of the tip protecting member 301 of the straight rod-shaped light emitter 30, the diameter D4 of the cylindrical body 302, or the diameter D5 of the small diameter cylindrical portion of the fixture 303, the diameter D2 is It is sufficiently smaller than the diameter D3 of the tip protecting member 301 of the rod-shaped light emitter 30, the diameter D4 of the cylindrical body 302, or the diameter D5 of the small diameter cylindrical portion of the fixture 303.

  According to such a configuration, in a state in which the straight bar-shaped light emitter 30 is inserted into the circumferential side bag body tunnel-like space 201, pressurized air is injected into the circumferential side bag body 20 so that the circumferential side bag body 20 is When inflated to a predetermined completed form, the inner diameter of the peripheral side tunnel-like cavity 201 is narrowed and tightened from the inner wall, whereby the straight bar-shaped light emitter 30 is firmly fixed (gripped) in the cavity. Further, if the pressure filled in the circumferential side bag body 20 is released, the inner diameter of the circumferential side bag body tunnel-shaped cavity 201 is expanded, so that the straight rod-shaped light emitter 30 can be easily pulled out from the cavity, The dismantling of the electric signboard 1 and the updating of the peripheral side bag body 20 can also be performed by a simple operation.

[1.2 Structure of bag]
Next, with reference to FIGS. 3 and 4, the detailed configuration of the bag body will be described using the peripheral side bag body 20 as an example.

  FIG. 3 is a detailed explanatory view of the peripheral side bag body 20. FIG. 3A shows the folded peripheral side bag 20 in a state where no pressurized air is injected. As is clear from the drawing, the peripheral side bag body 20 can be folded compactly in a state where no pressurized air is injected. Therefore, the circumferential side bag 20 is not bulky and is suitable for carrying and distribution.

  In this unexpanded state, the bottom surface side opening 206 and the top surface side opening 203 have a diameter D1 sufficiently larger than the diameters of D3 to D5, and have an inner diameter equal to or larger than the diameter D1 between them. The electric signboard 1 can be easily assembled by inserting the straight rod-shaped light emitter 30 through the peripheral side bag body tunnel-like space 201.

  In addition, the injection of the above-mentioned pressurized air is performed by a manual or electric pump (not shown) through a pressurized air injection part 207 with a backflow prevention valve provided on the top surface 202 as shown in FIG. Is possible.

  FIG. 4 is an explanatory view showing each of a plurality of flat resin sheet pieces constituting the circumferential side portion bag body 20 by region. As is clear from the figure, the peripheral side bag body 20 is substantially elliptical and has a top sheet 202 having a circular top surface opening 203 with a diameter D1 at the center, and is substantially elliptical and has a diameter at the center. A bottom sheet 205 having a circular bottom side opening 206 of D1, a top sheet 2041 and a back sheet 2042 constituting the circumferential side surface 204, and a middle pipe sheet 2043 constituting the circumferential side bag body tunnel-like space 201. It is formed by connecting each other through a welding line. For this joining, it is preferable to use, for example, high-frequency welder processing that has little thermal effect on the workpieces. All the sheets are light-transmitting, and the viewer sees the entire peripheral side bag body 20 in the completed form in which the light source is arranged in the peripheral side bag body tunnel-like cavity 201, and the whole is shining and perceived. . In this embodiment, all the sheets use polyurethane.

  The material and thickness of the middle pipe sheet 2043, the physical shape of the surface, and the like can be arbitrarily changed according to the advertisement / promotion mode. For example, by changing the material and thickness of the middle pipe sheet 2043, it is possible to change the optical (filter) characteristics of the transmitted light and change the color from the light source. It is also possible to adjust the amount of light from the light source by changing the material and thickness of the middle pipe sheet 2043. Furthermore, a heat-resistant material is used as the material of the intermediate pipe sheet 2043, or surface treatment is performed to provide minute irregularities on the surface, thereby avoiding heat fusion with the surface of the straight rod-shaped light emitter 30. You may comprise. The same thing may be realized not only in the middle pipe sheet 2043 but also in the other sheets 2041, 2042, 202 and 205.

[1.3 Structure of straight rod-shaped light emitter]
Next, a detailed configuration of the straight bar-shaped light emitter 30 will be described with reference to FIGS.

  FIG. 5 is an exploded perspective view showing an example of a straight rod-like light emitter. The straight rod-shaped light emitter 30 includes a light-emitting element assembly 307 having an elongated rectangular shape, a cylindrical body 302 having a circular section D4 having a diameter D4 that surrounds the light-emitting element assembly 307 and surrounds and transmits light, and a light-emitting element assembly. The upper end holding member 305 and the lower end holding member 306 that are disposed at the upper and lower ends of the tube 307 and are press-fitted into the tube 302 to hold the light emitting element assembly 307 to the tube 302, and the tip on the upper end side of the tube 302 are protected. A tip protecting member 301 having a circular cross section with a diameter D3, and a circular flange-shaped fixture 303 having a small-diameter cylindrical portion with an outer shape D5 that is arranged at the lower end of the cylindrical body 302 and supports the cylindrical body 302 vertically. . Each member is formed of a predetermined resin or the like, that is, the straight rod-shaped light emitter 30 also functions as a support column with the cylindrical body 302 as a center. Here, the attachment 303 supports the cylinder 302 vertically. However, for example, the attachment 303 may be attached to a wall surface, and the cylinder 302 may be attached to the tip of the attachment. The cylindrical body 302 is substantially horizontal with respect to the floor surface, and the bag surrounding the cylindrical body 302 is also substantially horizontal with respect to the floor surface.

  FIG. 6 is an exploded perspective view of the light emitting element assembly 307 corresponding to the light source portion of the straight rod-shaped light emitter 30. The light emitting element assembly 307 is formed by attaching an assembly in which the LED element array tapes 310a and 310b and the joining plates 309a and 309b are bonded to both surfaces of the elongated support plate 308, and fixing holes 320, 322, 326, 321, and 324, respectively. 327 is assembled by fixing with bolts 316 and 318 and nuts 317 and 319.

  In this example, the LED element array tapes 310a and 310b include unit blocks 311 configured by alternately arranging three LEDs 312 and two LED drive circuits 313 via two contacts 314. A plurality of units are connected to each other, and a cut is provided between the unit blocks 311. Note that at the end, the two contacts 314 are coupled to a connection line 315 connected to a power source. According to such a configuration, the LED element array tapes 310a and 310b can be easily cut at the cut line, and can be adjusted to an arbitrary length. Thereby, the light emitting element assembly 307 of various lengths can be manufactured relatively easily.

  FIG. 7 is an explanatory view showing the positioning structure of the elongated support plate 308 at the end of the cylindrical body 302. This figure shows the end of the elongated support plate 308 viewed from the upper end of the cylindrical body 302. The elongated support plate 308 is held in a rectangular groove at the center of the upper end holding member 305, and the elongated support plate 308 itself is press-fitted into the cylindrical body 302. According to such a structure, the light emitting element assembly 307 can be stably disposed at the center of the cylindrical body 302, whereby light can be applied to both the front and back surfaces.

  According to such a configuration, the LEDs 312 are arranged on both surfaces of the elongated support plate 308 inserted and fixed along the longitudinal direction of the cylindrical body 302 in the cylindrical body 302, so that the two directions differ by 180 degrees. Light can be emitted into the light source, thereby widely dispersing the light.

  According to the above configuration, when pressure is injected into the bag body 20 and the bag body 20 is inflated to a predetermined completed form in a state where the straight bar-shaped light emitter 30 is inserted into the tunnel-shaped space 201, the tunnel body When the inner diameter of the hollow space 201 is narrowed and tightened from the inner wall, the straight bar-shaped light emitter 30 is firmly fixed (gripped) in the tunnel-shaped space 201. At this time, since the straight bar-shaped light emitter 30 also serves as a support column, the bag body 20 can be supported on the horizontal floor or vertical wall via the straight bar-shaped light emitter 30. On the other hand, at this time, although the straight rod-shaped light emitter 30 is located outside the bag body, the light emitted from the straight rod-shaped light emitter 30 is tunnel-shaped because the tunnel-shaped void 201 is located at a position surrounded by the bag body. The advertising information drawn on the bag 20 is illuminated from behind (inside) through the resin sheet 2043 surrounding the void 201.

  On the other hand, if the compressed air filled in the bag body 20 is released by opening (see reference numeral 207 in FIG. 3), the inner diameter of the tunnel-like cavity 201 is expanded. By pulling out from 201, the dismantling of the electric signboard 1 and the updating of the bag body 20 can be performed by a simple operation. Therefore, the advertising information drawn on the bag body can be illuminated with a sufficient amount of light without accommodating a light emitter inside the bag body 20, and the structure is simple and inexpensive to manufacture. A decorative sign can be provided.

[2. Other Embodiments]
[2.1 Modification of bag shape]
In 1st Embodiment, the cross-sectional shape at the time of expansion | swelling of the surrounding side part bag body 20 is substantially elliptical shape, and advertisement and advertisement information were printed on the surface and the back, respectively. However, the present invention is not limited to such a configuration. Therefore, for example, as shown in FIG. 8, the cross-sectional shape of the peripheral side bag body 50 of the electrical signboard 40 may be substantially circular.

  As is clear from FIG. 8, various advertisement information 5041 is printed on the peripheral side surface 504 of the peripheral side bag body 50 over the entire periphery, and each advertisement / advertising information 5041 is arranged in the tunnel-shaped space 201. Illuminated by a straight rod-shaped light emitter 30. In addition, the same code | symbol is attached | subjected about the structure same as 1st Embodiment.

  According to such a configuration, since the circumferential side bag body 50 has a circular cross section, it is possible to provide the electric signboard 40 that can visually recognize the advertisement information 5041 from all angles. Moreover, since the circumferential side bag body 50 has a circular cross section, the electric signboard 40 that is strong against wind and the like can be obtained even when placed outdoors.

[2.2 Specific application examples]
In 1st Embodiment, it was set as the structure which makes the shape of the surrounding side part bag body 50 at the time of a predetermined completion form substantially cylindrical shape, and prints advertisement and advertisement information on the side surface.

That is, since the electric signboard 80 is configured to be movable on the floor surface, the signboard arrangement can be easily changed.

  According to such a configuration, since it is illuminated from the inside by the straight rod-shaped light emitter 30, not only is it easy to see even in the dark or far away, but at the same time, a bag having a high degree of freedom in design can be observed. Therefore, high advertising / advertising effects can be expected.

As is apparent from the figure, the peripheral side portion is tightened around the straight rod-shaped light emitter 30 (not shown) and has an elliptical cross section, and the front side 122 displays the characters “fresh fishery fishery shinbashi”. A bag body 120 is fixed, and a tip end bag body 110 having a shape imitating a fish by tightening the tip end is fixed to the tip end. That is, the peripheral side bag body 120 and the tip end bag body 110 arranged so as to be placed on the upper surface 121 of the circumferential side bag body 120 when the straight bar-shaped light emitter 30 disposed inside shines are It will be illuminated from the inside.

  A cart 90 is attached to the lower end of the straight rod-shaped light emitter 30 (not shown) instead of the fixture in the first embodiment. The carriage 90 includes a base 92 and casters 91 provided at the four corners on the lower surface side of the base 92. That is, since the electric signboard 100 is configured to be movable on the floor surface, the signboard arrangement can be easily changed.

  According to such a configuration, since it is illuminated from the inside by the straight rod-shaped light emitter 30, not only is it easy to see even in the dark or far away, but at the same time, a bag having a high degree of freedom in design can be observed. Therefore, high advertising / advertising effects can be expected.
