Description

Technical Field

[0006] , ,

[0007] ,

[0001] The present invention relates to a truck (ad truck) used for applications such as advertisements, promotions, event activities, etc., and particularly to an ad truck that enables various expression methods.

Background Art

[0002] So-called ad trucks (promotional trucks) that display advertisements on the loading platform of the truck and drive through the city are widely used and have a certain promotional effect.

[0003] Patent Document 1 discloses a technical idea of enhancing the promotional effect by using the loading platform as a stage in addition to displaying images on a video display (including sound) provided on the side of the loading platform.

[0004] However, in Patent Document 1, although it is described that the front part of the truck loading platform is a video display and a stage with an open front side and a closed rear side is deployed at the rear part of the truck loading platform, it is an extremely limited and narrow space, and even if a show or the like is held, the promotional effect is not fully exerted.

[0005] Also, Patent Document 2 describes image projection equipment provided on a moving body (truck), which consists of an irradiation device that irradiates light constituting an image and a projection plate that projects (reflects) the irradiated light. This is a means for generating and displaying a so-called Pepper's Ghost pseudo-stereoscopic image using a projection plate.

[0006] Furthermore, the projection plate is capable of transmitting light (half mirror) so that the state behind it can be visually recognized, and it is also described that a stage is provided behind and characters in costumes or the like are made to appear. By being able to confirm the image by Pepper's Ghost and the state behind, a technical idea of providing a more immersive image to the user is disclosed.

[0007] However, according to Patent Document 2, the dimensions of the stage are limited to the width of the truck, and it must be said that its use and effectiveness are extremely limited.

[0008] On the other hand, Patent Document 3 discloses a technical concept for a vehicle equipped with a mechanism that widens the internal space of a container by causing a widened chamber housed inside a container mounted on the frame of a vehicle such as a truck to protrude in the vehicle width direction.

[0009] However, according to Patent Document 3, the expanded space is listed as a religious chapel or a place to accommodate evacuees in the event of a disaster, but there is no mention of its use as an advertising truck.

[0010] As mentioned above, none of the patent documents disclose the technical concept of realizing all of the diverse means of advertising—such as displaying pseudo-3D images, augmented reality display of pseudo-3D images and real objects, and a large stage capable of providing high-quality performance—using the cargo bed of a truck. The fact that these have not been realized is a major problem. [Prior art documents] [Patent Documents]

[0011] [Patent Document 1] Japanese Patent Application Publication No. 2-55385 [Patent Document 2] Japanese Patent Publication No. 2022-25693 [Patent Document 3] Japanese Patent Publication No. 2020-29214 [Overview of the project] [Problems that the invention aims to solve]

[0012] This invention aims to solve the problems described above and aims to provide a vehicle (ad truck) equipped with a variety of advertising means. [Means for solving the problem]

[0013] In order to solve the above-mentioned problems, the vehicle according to the first aspect of the present invention is: A pseudo-3D image generation unit is provided inside the cargo bed to generate a pseudo-3D image, A window that allows the pseudo-3D image generated by the pseudo-3D image generation unit to be viewed from outside the truck, The cargo bed widening section allows the cargo bed to be widened in the width direction, A storage mechanism that allows the pseudo-3D image generation unit to be stored when the cargo bed is widened. It is characterized by being equipped with a box-shaped cargo bed.

[0014] Here, the vehicle used as an advertising truck is preferably a truck, but a similar vehicle such as a trailer may also be used.

[0015] Furthermore, the window section is preferably designed to allow visual inspection of the inside of the truck from the outside, but other display methods such as projecting onto a screen may also be used.

[0016] Furthermore, information can be provided using pseudo-3D images in any situation, whether the vehicle is in motion, briefly stopped, or parked for a long period of time. In addition, the cargo bed can be expanded in a suitable parking space to create a large stage, enabling a variety of advertising and promotional activities.

[0017] Furthermore, the pseudo-3D image generation unit can be retracted during stage setup to avoid interfering with the performance on stage.

[0018] Furthermore, the pseudo-3D image generation unit can be any device that can display images in a pseudo-3D manner.

[0019] In this way, the challenge of realizing a variety of advertising methods using the vehicle's cargo bed—including the display of pseudo-3D images generated by the pseudo-3D image generation unit, and the provision of a wide stage capable of delivering high-quality performances using the cargo bed widening mechanism—is solved.

[0020] Also, as a second aspect of the present invention, in the vehicle according to the first aspect, it may be characterized in that the window portion can display, superimposed, a pseudo-stereoscopic image generated by the pseudo-stereoscopic image generation unit and a two-dimensional or three-dimensional entity placed inside the loading platform, so as to be visible from the outside of the vehicle.

[0021] By doing so, the problem of realizing an augmented reality display of the generated pseudo-stereoscopic image and the two-dimensional or three-dimensional entity (which may also be referred to as an actual object) is solved.

[0022] Also, as a third aspect of the present invention, in the vehicle according to the first aspect, it may be characterized in that the pseudo-stereoscopic image generation unit includes an image information providing unit that provides image information and a half mirror that generates a virtual image of the image information in space.

[0023] In addition to providing still images or moving images by a display such as a liquid crystal or an organic EL, the image information providing unit may be an image projected onto a flat screen, or an image represented on a paper medium such as a photograph or a painting.

[0024] Here, by displaying a two-dimensional image as a virtual image through a half mirror, it can be displayed as a three-dimensional image to the eye, which is a technique called Pepper's Ghost and can be said to be a pseudo-stereoscopic image generation unit.

[0025] By doing so, it becomes possible to generate a pseudo-stereoscopic image by a simple method, and it becomes easier to solve the problem by the window portion visible from the outside.

[0026] Also, as a fourth aspect of the present invention, in the vehicle according to the third aspect, it may be characterized in that the pseudo-stereoscopic image generation unit has a mirror between the image information providing unit and the half mirror.

[0027] In other words, when the image generated by the pseudo-3D image generation unit is viewed through a half-mirror, the right-right orientation of the original image is reversed. If this is undesirable, the right-right orientation can be made the same as the original image by placing a mirror that performs total internal reflection in between.

[0028] Furthermore, as a fifth aspect of the present invention, in a vehicle according to the first aspect, The pseudo-3D image generation unit may be characterized by comprising: a long substrate on which point-type multi-color light-emitting diodes are arranged in a straight line; a rotation mechanism that rotates the center of the long substrate at high speed; and an image display mechanism that displays a pseudo-3D image in space by intermittently lighting some or all of the multi-color light-emitting diodes according to the rotation angle of the rotation mechanism.

[0029] Such technology has already been put into practical use, and in this invention, this technology is applied to an advertising truck. Compared to the aforementioned Peppers Ghost method, it can provide a more precise pseudo-3D image, and by incorporating it into a window that allows it to be viewed, a significant advertising effect can be obtained.

[0030] Furthermore, as a sixth aspect of the present invention, in a vehicle according to the first aspect, The window portion may be characterized by having a transparent plate provided on the right and / or right side of the cargo bed in the direction of vehicle travel, and a dimmable liquid crystal blind provided on the outer portion of the transparent plate.

[0031] Here, the transparent plate is preferably made of glass, but it may also be made of other materials such as plastic.

[0032] Furthermore, LCD blinds, also known as dimmable blinds or dimmable films, can be electrically controlled (opened and closed) without complex mechanisms, and can be instantly closed when advertising information is not being displayed.

[0033] In this way, viewers (those who view the information on the ad truck) can see inside the vehicle through the transparent panel with the LCD blinds on the windows open, and the advertising information provided through the windows, such as pseudo-3D images or real objects combined with pseudo-3D images, will be strongly impressed upon them.

[0034] Furthermore, as a seventh aspect of the present invention, in a vehicle according to the first aspect, The cargo bed widening section may be characterized by comprising a cargo bed body and a widening mechanism provided so as to be housed in the cargo bed body and movable substantially horizontally outward on the right and / or left side in the direction of vehicle travel.

[0035] This approach allows for the expansion of the cargo bed using a relatively simple mechanism, enabling the creation of a large platform capable of delivering high-quality performance in a short amount of time.

[0036] Furthermore, as an eighth aspect of the present invention, in a vehicle according to the first aspect, The cargo bed widening section may be characterized by having a cargo bed body and a widening mechanism folded to the right and / or left side of the cargo bed body in the direction of vehicle travel.

[0037] In this way, the cargo bed can be easily widened by deploying the folded widening mechanism, creating a larger platform. [Effects of the Invention]

[0038] According to the vehicle (ad truck) of the present invention, it has become possible to realize all of the diverse means of advertising, such as the display of pseudo-3D images, augmented reality display of pseudo-3D images and real objects, and a large stage capable of providing high-quality performance, using the cargo bed of a truck. [Brief explanation of the drawing]

[0039] [Figure 1] This is a schematic perspective view of a vehicle according to the first embodiment of the present invention. [Figure 2]This is a cross-sectional view of a vehicle according to the first embodiment of the present invention, before widening. [Figure 3] This is a cross-sectional view of a vehicle after widening according to the first embodiment of the present invention. [Figure 4] This is an explanatory diagram of the display state of a vehicle according to the first embodiment of the present invention. [Figure 5] This is a cross-sectional view of a vehicle according to a second embodiment of the present invention, before widening. [Figure 6] This is a cross-sectional view of a vehicle according to a third embodiment of the present invention, before widening. [Figure 7] This is an explanatory diagram of a pseudo-3D image generation unit for a vehicle according to a fourth embodiment of the present invention. [Figure 8] This is an explanatory diagram of a pseudo-3D image generation unit for a vehicle according to a fourth embodiment of the present invention. [Figure 9] This is a cross-sectional view of the widened cargo bed portion of a vehicle according to a fifth embodiment of the present invention. [Modes for carrying out the invention]

[0040] Embodiments of the present invention will be described below with reference to the drawings. In the following, the scope necessary for explaining how to achieve the objectives of the present invention will be schematically shown, and the scope necessary for explaining the relevant parts of the present invention will be mainly explained, with any parts that are omitted from explanation being covered by prior art.

[0041] Figure 1 is a schematic perspective view of a vehicle according to the first embodiment of the present invention. The ad truck 1 has two window sections 50, each consisting of a liquid crystal blind 52 provided on the right side in the direction of travel of the cargo bed 10 located above the wheels 2, and a transparent glass plate 51 provided inside the liquid crystal blind 52 and having approximately the same dimensions as the liquid crystal blind 52.

[0042] The liquid crystal blind 52 is also called a dimming film and is preferably a PET film with a transparent conductive film attached that sandwiches liquid crystals, becoming opaque when the transparent conductive film is not energized because the liquid crystals are unevenly oriented, and transparent when the transparent conductive film is energized because the liquid crystals are evenly oriented, but other structures are also acceptable.

[0043] Figure 2 is a cross-sectional view perpendicular to the direction of travel, taken from the rear of the cargo bed, showing the state of the vehicle according to the first embodiment of the present invention before the cargo bed is widened. The cargo bed 10 has a cargo bed body 101, a left widened section 102, and a right widened section 103. In this figure, the cargo bed 10 is in an unwidened state, and the cargo bed body 101, the left widened section 102, and the right widened section 103 are in a retracted state.

[0044] Furthermore, in this embodiment, in order to provide advertising information from both the left and right sides in the direction of travel of the vehicle, a window section 50 is provided in the left widened section 102 and the right widened section 103, consisting of a transparent glass plate 51 and a liquid crystal blind film 52 attached to the outside of the transparent plate 51.

[0045] Here, the cargo bed body 101 has a wall at the front in the direction of travel, a wall at the rear in the direction of travel, a ceiling, and a floor. However, both sides in the direction of travel, at least the parts where the transparent plate 51 is provided, are almost open, and these parts are covered by the side walls of the left widened section 102 and the right widened section 103.

[0046] Next, a fixed beam 20 is provided in the upper part of the interior of the cargo bed 10, spanning between the front wall and the rear wall of the cargo bed body 101 in the direction of travel, and a storage mechanism 30 (details will be described later) is provided on this fixed beam 20.

[0047] Furthermore, a holding portion 40 is provided at the lower end of the storage mechanism 30, and a planar display portion 41, which serves as a pseudo-3D image generation unit, is fixed to the holding portion 40. Here, the planar display portion 41 can be any type of display, such as an LCD or OLED, that can display still images or videos.

[0048] Furthermore, a half-mirror 60 is provided below the planar display section 41 at an angle of approximately 45 degrees to the horizontal, such that, when viewed from outside the vehicle, the far side is at the top and the near side is at the bottom. The half-mirror 60 is held in place by the holding section 40 via a rotatable hinge 61, and a stopper or the like can be used as appropriate to stop it in the position shown in the figure.

[0049] Although the angle between the half-mirror 60 and the horizontal was set to approximately 45 degrees, depending on the positional relationship between the viewer (window section 50) and the pseudo-stereoscopic image generation unit, it is possible that a range of 35 to 50 degrees, rather than being limited to 45 degrees, may produce a better virtual image. Therefore, the angle was set to approximately 45 degrees to include this range.

[0050] The half-mirror 60 is a mirror that transmits some light and reflects some light, and the base material is a transparent glass plate, acrylic plate, film, etc., on which a mirror layer of metal or dielectric material is deposited, and it includes not only those in which the ratio of reflected light to transmitted light is 1:1, but also those in other ratios.

[0051] In this way, from the perspective of an observer outside the vehicle, the image displayed on the planar display unit 41, reflected by the half-mirror 60, appears as a virtual image, as if it were located directly ahead of the half-mirror 60.

[0052] Furthermore, when providing information on both the left and right sides of the vehicle, it is preferable to place a dark curtain 70 of a low brightness color, such as black, between them, thereby providing a clearer image (virtual image) reflected by the half mirror 60. The dark curtain 70 is held to the fixed beam 20 via a winding mechanism 71.

[0053] Figure 3 is a cross-sectional view perpendicular to the direction of travel, taken from the rear of the cargo bed, showing the state of the vehicle after the cargo bed has been widened according to the first embodiment of the present invention. The widened cargo bed is formed by a drive mechanism (not shown) that moves horizontally, with the left widened section 102 moving to the left and the right widened section 103 moving to the right, leaving the cargo bed body 101 in place.

[0054] The drive mechanism can be any mechanism that allows for horizontal movement, such as a mechanism using a hydraulic cylinder, or a mechanism using a motor, pinion, and rack.

[0055] Although widening was described as being possible in two directions (left and right), it is also possible to widen it in only one direction. In that case, the structure would be simplified and costs would be reduced.

[0056] Here, in synchronization with the widening operation, the holding unit 40, which holds the planar display unit 41 as the pseudo-stereoscopic image generation unit, is stored by the storage mechanism 30 so as to be close to the fixed beam 20, thereby eliminating any obstruction to the use of the space below and ensuring the safety of the planar display unit 41.

[0057] For the storage mechanism 30, known technologies such as elevator drive methods (rope type, hydraulic type, linear motor type, etc.) and pantographs can be used.

[0058] Furthermore, the half-mirror 60 is also rotated around the hinge 61 by a rotation mechanism or coil spring mechanism (not shown) that uses a known motor or the like, which is part of the storage mechanism 30, to be stored horizontally below the holding part 40, and is stored upward in conjunction with the holding part 40.

[0059] Similarly, the blackout curtain 70 is also rolled up by the winding mechanism 71, which is part of the storage mechanism 30, and stored just below the fixed beam 20. The winding mechanism can be a known technology using a motor, coil spring, etc.

[0060] Next, the operation of the first embodiment of the present invention will be described.

[0061] Figure 4 is an explanatory diagram illustrating the display state of a pseudo-three-dimensional image and an actual object in a vehicle according to the first embodiment of the present invention.

[0062] In all conditions, including while the ad truck is in motion, the cargo bed 10 is kept in a non-extended state, the liquid crystal blind 52 is in an open state, and the planar display unit 41, which acts as a pseudo-3D image generation unit, displays an image RI (still image or video).

[0063] The image information for the flat display unit 41 shall be provided by information provision means (not shown), such as a server, PC, tablet, or smartphone.

[0064] Then, the image RI reaches the viewer P's eye via the half-mirror 60, and viewer P appears to exist as a virtual image VI behind the half-mirror 60 in the straight-ahead direction.

[0065] Meanwhile, on the other side of the half-mirror 60, performers are positioned and perform in conjunction with the images displayed on the screen.

[0066] In other words, a two-dimensional or three-dimensional entity 80, such as a person, a costumed character, a stuffed animal, or information on paper, is placed near the location where the virtual image VI is formed on the back (rear) side of the half-mirror 60. The person or costumed character may perform actions such as dancing, singing, or talking, and may also interact with the pseudo-three-dimensional image (virtual image VI) generated by the half-mirror 60.

[0067] In this way, the viewer P perceives the pseudo-3D image as a composite of the information and movement (acting) of the actual object, and a greater advertising effect can be expected.

[0068] On the other hand, if the ad truck is to be parked and a more elaborate performance is to be provided, the cargo bed body 101 is left as is, and the left widening section 102 is widened to the left, and the right widening section 103 is widened to the right.

[0069] Synchronized with the widening operation, the storage mechanism 30 is activated, and the planar display unit 41, half mirror 60, and blackout curtain 70, which serve as the pseudo-3D image generation unit, are stored just below the upper fixed beam 20, so as not to interfere with the use of the space below.

[0070] Furthermore, while it is preferable to make the window section 50 opaque by operating the liquid crystal blind 52, there may be situations where it is acceptable to leave it transparent so that the interior can be seen.

[0071] Once the expansion and retraction operations are complete, a large stage is formed, on which performers (including stuffed animals) can deliver powerful performances, advertising the products being sold or events being held, leaving a strong impression on the audience.

[0072] Although not shown in the diagram, stairs or an entrance / exit to the stage may be provided at the rear of the loading platform 101 for ascending and descending to the stage, or legs may be extended downwards to support the widened section.

[0073] Next, a second embodiment of the present invention will be described. Note that parts common to the first embodiment may be represented by the same symbols, and their descriptions may be omitted.

[0074] Figure 5 is a cross-sectional view taken perpendicular to the direction of travel, viewed from the rear of the cargo bed, showing the state of the vehicle before the cargo bed was widened according to the second embodiment of the present invention.

[0075] In this embodiment, advertising information can be provided only from one side of the vehicle's direction of travel (the left side in the diagram).

[0076] In other words, a window section 50 is provided on the left side in the direction of travel of the vehicle, and only one set of a planar display section 41, a half mirror 60, and a blackout curtain 70 is provided as a pseudo-3D image generation unit.

[0077] In this configuration, the dimensions of the planar display unit 41 and the half-mirror 60, which serve as the pseudo-3D image generation unit, can be increased compared to the case where they are provided on both sides. Consequently, the window unit 50 can also be enlarged, providing the viewer with a more impactful image.

[0078] Furthermore, it becomes possible to enlarge the size of the people or stuffed animals that collaborate with the images, or to expand their activity area.

[0079] When installing on one side, it is preferable from an advertising effect to install it on the left side, which is closer to the sidewalk, but depending on the situation, it may be better to install it on the right side.

[0080] Furthermore, the storage operation during widening is the same as in the first embodiment, so we will omit the explanation.

[0081] Next, a third embodiment of the present invention will be described. Note that parts common to the first and second embodiments will use the same symbols, and their descriptions may be omitted.

[0082] Figure 6 is a cross-sectional view perpendicular to the direction of travel, taken from the rear of the cargo bed, showing the state of the vehicle before widening of the cargo bed according to the third embodiment of the present invention.

[0083] This embodiment has a pseudo-stereoscopic image generation unit comprising a projector 45, a fully reflective full mirror 46, and a screen 47. Unlike the second embodiment, the half mirror 60 is installed at an angle of approximately 45 degrees to the horizontal, with its upper end closer to the window 50 and its lower end further away from the window 50.

[0084] Here, when the image to be displayed is sent from the projector 45, the image is reflected by the full mirror 46 (which can also be called a total reflection mirror) and projected onto the screen 47.

[0085] The viewer observes this image through the half-mirror 60 and perceives it as a pseudo-three-dimensional image (virtual image) behind (towards) the half-mirror 60.

[0086] The rest of the configuration is the same as in the second embodiment, with the projector 45 and full mirror 46 fixed to the holding part 40 and stored upward when the cargo bed is widened by the storage mechanism 30.

[0087] As for screen 47, it should be manually or automatically rolled up and stored above or at the rear of the stage when it is widened.

[0088] Although this embodiment has been described as providing image information to one side of an advertising truck, it can also be applied to providing image information to both sides.

[0089] Here, the full mirror 46 has the function of reversing the left and right sides of the image sent from the projector 45. It can be omitted if this is not necessary. Also, in the first and second embodiments, if left and right reversal of the image is necessary, the full mirror can be used as appropriate.

[0090] Next, a fourth embodiment of the present invention will be described. Note that parts common to the first to third embodiments will use the same symbols, and their descriptions may be omitted.

[0091] Figures 7 and 8 are explanatory diagrams of the pseudo-3D image generation unit of a vehicle according to the fourth embodiment of the present invention.

[0092] As a pseudo-3D image generation unit, an LED bar 141, in which many multi-color LEDs 140 are arranged in a straight line, is held rotatably on a central axis 142. The central axis 142 is held by three legs 143 on its outer non-rotating portion and is installed inside the window 50.

[0093] Here, the LED bar 141 is rotated at high speed around the central axis 142 by a drive mechanism (not shown) along the trajectory indicated by the outer circle, and some or all of the LEDs 140 contained in the LED bar 141 are intermittently lit according to an image sequence provided from the outside. As a result, due to the afterimage effect of the eye, pseudo-stereoscopic images 144 and 145 as shown in Figure 8 can be observed in space.

[0094] By providing these pseudo-stereoscopic images 144 and 145 in space, either independently or in collaboration with the physical object 80, effective advertising and promotion can be carried out.

[0095] In this embodiment, when the cargo bed is widened, the LED bar 141, central axis 142, and leg portion 143 may be folded using the storage mechanism 30 and stored above the cargo bed body 101, similar to the first embodiment, or the display direction may be changed so that it can be observed from the rear of the truck, and the pseudo-stereoscopic image may continue to be displayed.

[0096] Next, a fifth embodiment of the present invention will be described. Note that parts common to the first to fourth embodiments will use the same symbols and their descriptions may be omitted.

[0097] In the first embodiment, the cargo bed widening section was moved in parallel to the cargo bed, but in this embodiment, the cargo bed widening section is folded into the vicinity of the cargo bed body.

[0098] Figure 9 is a cross-sectional view of the widened cargo bed of a vehicle according to the fifth embodiment of the present invention, taken perpendicular to the direction of travel and viewed from the rear of the cargo bed in the direction of travel. Although only the right side of the widened cargo bed is shown, it is possible to widen the left side in the same way.

[0099] The right widening section 103 has a first ceiling section 103C1, a second ceiling section 103C2, a right wall section 103S, a first floor section 103F1, and a second floor section 103F2. Hinge joints are provided between each section, and at the contact points with the ceiling section 101C of the cargo bed body 101 and the floor section 103F of the cargo bed body 101, respectively, extending in the direction of cargo bed movement.

[0100] Here, the pair T1 between the ceiling portion 101C of the cargo bed body 101 and the first ceiling portion 103C1 is such that the side of the ceiling portion 101C of the cargo bed body 101 is fixed, and the pair T6 between the floor portion 103F of the cargo bed body 101 and the first floor portion 103F1 is such that the side of the floor portion 101F of the cargo bed body 101 is fixed.

[0101] Furthermore, the pair T4 between the second floor section 103F2 and the side wall section 103S is designed to move only on a horizontal plane that extends from the floor section of the cargo bed body 101. This can be achieved, for example, by a horizontal rail-like structure that restricts vertical movement.

[0102] The other pairs T2, T3, and T5 are mounted so that their parts are rotatable relative to each other.

[0103] With this structure, once the widening operation is initiated by a drive mechanism (not shown), it progresses as shown in Figure 9 (A), (B), and (C), and the widened state is completed.

[0104] In this embodiment, since there are no obstacles on the floor of the cargo bed body 101 even when it is not widened, the degree of freedom of use is increased.

[0105] However, in this embodiment, the structure becomes complex when a window section is provided in a non-widened state.

[0106] While various modifications of this folding method are conceivable, these are also included within the technical concept of the present invention. [Industrial applicability]

[0107] This invention allows for the realization of a variety of advertising methods—including the display of pseudo-3D images, augmented reality display of pseudo-3D images and real objects, and a large stage capable of providing high-quality performance—all using the cargo bed of a truck. Therefore, it can be used for advertising in a wide range of industries and has great industrial potential. [Explanation of Symbols]
