[0004] [Non-Patent Document 1] Tokyo Labor Bureau, "Promoting Safety and Health Measures in the Land Freight Transportation Business," [online], [Retrieved July 3, 2025], Internet <URL: https: / / jsite.mhlw.go.jp / tokyo-roudoukyoku / news_topics / kyoku_oshirase / roudou_kijun / rikuun2023_00001.html> Summary of the Invention [Problem to be solved by the invention]

[0005] Currently, 70% of all work-related accidents in the land freight transportation industry occur during loading and unloading operations (Non-Patent Document 1). Even though vehicles should not be moved during standby and loading and unloading operations, accidents can occur when vehicles start moving during standby and unloading operations due to careless driving and unloading operations. Signs and posters are used to raise awareness.

[0006] Careless starting of a vehicle while loading and unloading operations are in progress is a dangerous and serious accident that can not only cause personal injury to people in the vicinity of the vehicle, but also cause serious damage to the environment due to the spillage of the vehicle's cargo (e.g., powdered materials such as cement).

[0007] Patent Document 1 discloses a signboard to draw attention while driving as an accident prevention measure, stating that "when attached to the fin of an automobile's air conditioning vent 5, the signboard 1 is always in the driver's line of sight while driving, effectively drawing the driver's attention" (paragraph 0008). However, Patent Document 1 is intended to draw attention while driving, and is not suitable for industries such as loading and unloading work, which is carried out while the vehicle is parked, and does not solve the problem of the likelihood of industrial accidents occurring during loading and unloading work.

[0008] In view of the above circumstances, the purpose of this disclosure is to prevent the driver from inadvertently starting the vehicle while waiting or loading and unloading work is being performed while the vehicle is stopped, and further to prevent accidents such as personal accidents that may result from this. [Means for solving the problem]

[0013] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0014] I. First Embodiment

[0015] 1. Composition of vehicle signboards

[0016] Fig. 1 is a perspective view showing a vehicle signboard according to a first embodiment of the present disclosure from one side, and Fig. 2 is a perspective view showing the vehicle signboard from the back side.

[0017] The vehicle signboard 1 has a main body 100 and a bending portion 200.

[0018] The main body 100 is a plate made of a durable material such as plastic. The main body 100 is typically made of an opaque material, but may be translucent. The main body 100 is, for example, rectangular in plan view. The corners of the rectangle may be right angles or rounded (with a rounded corner). In this document, when we refer to corners, rectangles, etc., we mean not only figures consisting of straight lines only, but also figures with rounded corners (with a rounded corner).

[0019] The main body 100 has an interior surface 101, an exterior surface 102 which is the reverse side of the interior surface 101, and an opening 106. The interior information display unit 103 is provided on the interior surface 101 and displays interior information 111 for the driver in the driver's seat 301 of the vehicle 300. The exterior information display unit 104 is provided on the exterior surface 102 and displays exterior information 112 for people outside the vehicle 300 (for example, field workers other than construction workers). The interior information 111 for the driver is, for example, safe operation standard information and illustrations showing accident risk locations during loading and unloading work of the vehicle 300. The safe operation standard information indicates the order of a series of actions the driver will take from stopping to starting the vehicle, and the manager's intentions regarding the driver.

[0020] For example, the safety operation standard information assuming the operation of loading powdered materials such as cement into the tank of vehicle 300 is text information such as (1) safety harness attached, (2) ratchet, (3) loading with hatch fully open, (4) loading hatch closed, (5) air vent hatch closed, (6) ratchet stowed, (7) final check around the vehicle, etc. Accident risk points during loading and unloading operations of vehicle 300 depicted in the illustration for this operation are, for example, ratches related to operations (2) and (6) and manhole hatches related to operations (3) to (5). The illustration preferably depicts the silhouette of the special vehicle so that anyone can understand the accident risk points at a glance.

[0021] As another example, the safety operation standard information for an operation in which a hose mounted on a tank of vehicle 300 is connected to a silo and powder and granular material in the tank is poured into the silo includes text information such as (1) ratchet, (2) after hose connection, PTO (on), (3) start of pumping, end of pumping, (4) after PTO (off), hose retraction, (5) hose retraction OK, (6) ratchet retraction OK, (7) final check around the vehicle. Accident risk points during loading and unloading operations of vehicle 300 depicted in the illustration for this operation are, for example, ratchet related to operations (1) and (6) and hose related to operations (2) to (5). The illustration preferably depicts the silhouette of a special vehicle so that anyone can understand the accident risk points at a glance.

[0022] The outside vehicle information 112 for people outside the vehicle is, for example, information indicating that the vehicle 300 is engaged in loading and unloading work and an illustration indicating accident risk locations during loading and unloading work on the vehicle 300. The information indicating that work is in progress is text information such as "loading and unloading work in progress." The accident risk locations depicted in the illustration during loading and unloading work on the vehicle 300 are ratchet stops, manhole hatches, and hoses. The illustration preferably depicts the silhouette of a special vehicle so that anyone can understand the accident risk locations at a glance.

[0023] The opening 106 is provided in an upper portion 105 of the main body 100. The upper portion 105 is above the interior information display portion 103 and the exterior information display portion 104, and is a portion that does not interfere with the interior information display portion 103 or the exterior information display portion 104. The opening 106 is provided near an upper edge 109 of the rectangular main body 100, typically approximately parallel to the upper edge 109. The opening 106 penetrates between the interior surface 101 and the exterior surface 102 of the vehicle.

[0024] A reinforcing portion 110 may be provided on the top edge 109 of the main body 100. The reinforcing portion 110 reinforces the narrow portion between the top edge 109 of the main body 100 and the opening 106. The reinforcing portion 110 is, for example, a plastic rail. Note that a reinforcing portion (not shown) similar to the reinforcing portion 110 may also be provided on the bottom edge, left edge, and / or right edge of the main body 100. Note that the reinforcing portion 110 on the top edge 109 and the reinforcing portions on the bottom edge, left edge, and right edge may be provided in all (four locations), in some locations (one to three locations), or not at all.

[0025] The bending portion 200 is provided on the upper portion 105 of the main body 100. The bending portion 200 is made of a flexible and pliable material, and may include, for example, synthetic rubber and / or polyester. The thickness of the bending portion 200 may be, for example, approximately 1 mm to 8 mm. Specifically, the bending portion 200 is held within the opening 106 by having one end 204 that has passed through the opening 106 fixed to the bending portion 200 by a fixing device 203. The fixing device 203 may be, for example, a spring hook or eyelet. If the bending portion 200 deteriorates or is damaged, it can be easily repaired (replaced) by combining the existing main body 100 with a new bending portion 200 and fixing them with the fixing device 203. As a modified example, the main body 100 and the bending portion 200 may be configured as a continuous single unit rather than combining separate members.

[0026] The bending portion 200 can at least be configured to have a curved shape having an outer arc surface 201 on the vehicle interior surface 101 side and an inner arc surface 202 on the vehicle exterior surface 102 side. When configured to have a curved shape, the bending portion 200 does not face at least a part (most part) of the vehicle exterior information display unit 104. Typically, when configured to have a curved shape, the bending portion 200 does not face the entire vehicle exterior information display unit 104. Note that the bending portion 200 may further be configured to have an inverse curved shape in which the vehicle interior surface 101 side has an inner arc and the vehicle exterior surface 102 side has an outer arc.

[0027] Fig. 3 is a side view of a vehicle sign attached to a vehicle, Fig. 4 shows the vehicle sign attached to a vehicle as seen from the driver's seat, and Fig. 5 shows the vehicle sign attached to a vehicle as seen from outside the vehicle.

[0028] The bent portion 200 is suspended from the inside of the vehicle 300 on the upper end of the open power window 302 so that the outer surface 102 faces the inner surface 303 of the power window 302 of the driver's seat 301 of the vehicle 300. With the bent portion 200 present, the power window 302 is raised to its upper limit. As shown in FIGS. 4 and 5 (reflection of the side mirror 304 in FIG. 5), when the vehicular sign 1 is attached to the vehicle 300 in this manner, the main body 100 conceals at least a portion of the side mirror 304 of the driver's seat 301 as seen by the driver at the driver's seat 301. This at least a portion of the side mirror 304 is preferably 20% or more, and most preferably 100%.

[0029] It is desirable that the main body 100 and the bending portion 200 each have a width such that the main body 100 conceals at least a part of the side mirror 304 of the driver's seat 301 as seen by the driver in the driver's seat 301, even when the bending portion 200 is hung on the power window 302 by moving it to either of the ends 305 in the vehicle's fore-and-aft direction (left and right direction as seen from the driver's seat 301).

[0030] For example, the area of ​​main body 100 may be 20% or more of the area of ​​side mirror 304 of driver's seat 301 (the area of ​​the part of side mirror 304 that is normally exposed when side mirror 304 is closed). For example, main body 100 may be rectangular, approximately 25 cm to 50 cm wide and 25 cm to 50 cm long. For example, main body 100 is highly convenient if it is sized to be able to be stored in the dashboard of vehicle 300 or the like. Bending portion 200 may be, for example, 47 cm wide or less, and the total vertical length from top side 109 of main body 100 may be approximately 8 cm to 35 cm.

[0031] The bent portion 200 is suspended from the upper end of the power window 302 from inside the vehicle 300, and the power window 302 is raised to its upper limit with the bent portion 200 present. At this time, the power window 302 pushes the bent portion 200 into the glass run channel 306, and the bent portion 200 is clamped by the glass run channel 306.

[0032] 5, when the power window 302 is lowered, the bending portion 200 is kept sandwiched in the glass run channel 306 due to the frictional force between the power window 302 and the bending portion 200. Regardless of the up / down position (open / close height) of the power window 302, the main body 100 conceals at least a part of the side mirror 304 of the driver's seat 301 as seen by the driver in the driver's seat 301.

[0033] When removing the vehicle signboard 1 from the vehicle 300, the main body 100 is pulled downward to remove the bent portion 200 from the glass run channel 306.

[0034] As a modified example, the opening 106 may be inclined so that the front end 107 is lower and the rear end 108 is higher. The front end 107 is the end located on the front side of the vehicle 300 (the left end of the vehicle interior surface 101) when the vehicle exterior surface 102 faces the inner surface 303 of the power window 302 of the driver's seat 301 of the vehicle 300. The rear end 108 is the end located on the rear side of the vehicle 300 (the right end of the vehicle interior surface 101). With this configuration, due to the inclination, when the bent portion 200 is hung on the power window 302, the main body 100 hangs toward the front of the vehicle 300 so that the bent portion 200 contacts the rear end 108 of the opening 106. In other words, the main body 100 is positioned closer to the front of the vehicle 300. This allows the main body 100 to conceal a larger portion of the side mirror 304 of the driver's seat 301 as seen by the driver at the driver's seat 301.

[0035] 2. How to use vehicle signs

[0036] FIG. 6 shows how to use the vehicle sign.

[0037] When using the vehicle signboard 1, the driver parks the vehicle 300 at a work location. The driver opens at least a portion of the power window 302 of the driver's seat 301 of the vehicle 300 (step S11). The driver hangs the bent portion 200 on the power window 302 from inside the vehicle 300 so that the vehicle exterior surface 102 faces the inner surface 303 of the power window 302 (step S12). The driver raises the power window 302 to its upper limit while the bent portion 200 is present (step S13). As a result, the main body 100 conceals at least a portion of the side mirror 304 of the driver's seat 301 as seen by the driver in the driver's seat 301. This prevents the driver from starting the vehicle 300 unless the driver removes the vehicle signboard 1.

[0038] Next, a method for removing the vehicle signboard 1 after the loading and unloading operation is completed will be described. When the driver starts driving, he or she looks at the side mirror 304 and notices that the view on the side mirror 304 is obstructed by the vehicle signboard 1. If the power window 302 is up, the driver lowers and opens the power window 302 (step S21). The driver removes the vehicle signboard 1 from the vehicle 300 by pulling out the bent portion 200, which is sandwiched and held in the glass run channel 306, from the glass run channel 306 (step S22). The driver stores the vehicle signboard 1 in the dashboard or the like, and then starts driving.

[0039] 3.Summary

[0040] According to this embodiment, a vehicle sign 1 is provided in which the main body 100 and the bending portion 200 are combined and integrated. The vehicle sign 1 can be installed inside the vehicle by clamping the flexible bending portion 200 between the power window 302. To remove the vehicle sign 1, the driver lowers the power window 302 and pulls out the bending portion 200 that is clamped and bitten into the glass run channel 306. This is expected to solve the problem in the transportation industry, which has recently been an issue in the transportation industry using vehicles, where "driving and loading and unloading operations" are separate tasks.

[0041] When the driver starts the vehicle 300, the driver naturally checks the side mirror 304 to confirm safety and then starts the vehicle 300. Therefore, if an irregularity occurs and the driver looks at the side mirror 304 to start the vehicle 300 even while loading and unloading work is in progress, the driver's view on the side mirror 304 is obstructed by the vehicle signboard 1. Furthermore, the in-vehicle information 111 (accident risk, etc.) for the driver displayed on the vehicle signboard 1 naturally comes into the driver's field of vision. Therefore, by making the driver aware of the in-vehicle information 111 (accident risk, etc.), it is possible to prevent accidents when starting the vehicle during loading and unloading work.

[0042] When the vehicle signboard 1 is installed in the vehicle 300, the in-vehicle information display unit 103 for the driver is provided on the inside surface 101 of the vehicle and can be seen by the driver in the driver's seat 301. The outside information display unit 104 for people outside the vehicle (such as field workers other than construction workers) is provided on the outside surface 102 of the vehicle and can be seen from outside the vehicle through the power window 302. The inside information 111 for the driver and the outside information 112 for people outside the vehicle can be presented simultaneously on both sides of the vehicle signboard 1.

[0043] To alert the driver inside the vehicle, the vehicle sign 1 is installed on the power window 302 of the driver's seat 301, and the vehicle sign conceals at least a portion of the side mirror 304 of the driver's seat 301. The vehicle sign 1 enters the field of view of the driver who is looking at the side mirror 304. If at least a portion of the side mirror 304 is concealed and the vehicle sign 1 enters the field of view, this becomes a serious obstacle for the driver when starting the vehicle 300. For this reason, when checking before starting, the driver will always take action to remove the vehicle sign 1 because it obstructs the field of view and becomes an eyesore. This provides an effective alert to prevent careless starting and accidents. If the vehicle sign is installed in front of the driver's seat 301, the side mirror 304 is completely blocked from the driver's field of view, which is even more effective.

[0044] After completing the work and before starting to drive, the driver notices that the vehicle sign 1 blocks the view on the side mirror 304 (action 1). The driver lowers and opens the power window 302 to remove the vehicle sign 1 (action 2). The driver removes the vehicle sign 1 by pulling out the bent portion 200 that is pinched and held in the glass run channel 306 (action 3), and after storing the vehicle sign 1 in the dashboard or the like, starts driving. In other words, removing the vehicle sign 1 requires three conscious steps. Conversely, the vehicle sign 1 cannot be removed with a single, careless action. In this way, the vehicle sign 1 plays a role in making the driver consciously switch between "driving and loading and unloading work."

[0045] Furthermore, for the driver, the vehicular signboard 1 not only hides the side mirror 304 but also serves to display in-vehicle information 111 (safety operation standard information in this example) required for work. The presence of the in-vehicle information 111 motivates the driver to attach the vehicular signboard 1 to the vehicle 300. This reduces the number of situations in which the vehicular signboard 1 is not attached to the vehicle 300 in the first place.

[0046] As for the outside-vehicle information 112 for people outside the vehicle, the vehicle sign 1 can be useful in solving various issues in the transportation industry, such as the recent issue of treating "driving and loading and unloading work" as separate tasks. By providing the vehicle sign 1 that can be installed on opening and closing mechanisms such as the power window 302 and door, it can be used for various purposes such as safety measures and accident prevention for occupations that use the vehicle 300.

[0047] By using the power window 302 and sandwiching the flexible and pliable bending portion 200 in the glass run channel 306, the vehicle sign 1 can be installed on the inner surface 303 of the power window 302 (i.e., inside the vehicle), and is therefore not affected by weather such as wind and rain. The flexible and pliable bending portion 200 allows it to be adapted to various vehicle models regardless of the shape and size of the power window 302 and the glass run channel 306.

[0048] II. Second Embodiment

[0049] Hereinafter, the same reference numerals will be used to designate the configurations and the like that have already been described, and the description will be omitted, and the differences will be mainly described.

[0050] Fig. 7 shows a first state of a vehicle sign according to a second embodiment of the present disclosure, and Fig. 8 shows a second state of the vehicle sign.

[0051] The vehicle signboard 2 has the same configuration as the vehicle signboard 1 of the first embodiment, but also includes a displacement section 120. The displacement section 120 is a plate made of a durable material such as plastic, and has, for example, a rectangular shape in a plan view. The displacement section 120 is slightly smaller than half the size of the main body 100.

[0052] The displacement portion 120 can be opened and closed with the center portion 131 of the main body 100 as a fulcrum. The mechanism that enables opening and closing is not limited. In this example, a plurality of openings 133 are provided in the center portion 131 of the main body 100, and a corresponding plurality of openings 132 are provided near one end of the displacement portion 120. The openings 132 of the displacement portion 120 and the openings 133 of the main body 100 are passed through a ring 134. The displacement portion 120 can be displaced via the ring 134.

[0053] The displacement portion 120 is provided on the interior surface 101 of the main body 100. The displacement portion 120 has a first surface 121 and a second surface 122 behind the first surface 121. The displacement portion 120 is displaceable between a first state and a second state. In the first state, the first surface 121 is exposed and the second surface 122 is hidden, exposing a first interior surface 123 that is part of the interior surface 101. In the second state, the first surface 121 is hidden and the second surface 122 is exposed, exposing a second interior surface 124. The second interior surface 124 is the portion of the interior surface 101 excluding the first interior surface 123.

[0054] The vehicular signboard 2 further includes a first interior information display unit 127 and a second interior information display unit 128. As shown in Fig. 7, the first interior information display unit 127 is provided on the first surface 121 and the first interior surface 123 that are exposed in the first state, and displays first interior information 129. As shown in Fig. 8, the second interior information display unit 128 is provided on the second surface 122 and the second interior surface 124 that are exposed in the second state, and displays second interior information 130 that is different from the first interior information 129.

[0055] 7, the first in-vehicle information 129 is, for example, safety operation standard information assuming the operation of loading powdered material such as cement into the tank of the vehicle 300, and is textual information such as (1) safety harness attached, (2) ratchet, (3) loading with hatch fully open, (4) loading hatch closed OK, (5) air vent hatch closed OK, (6) ratchet stowed OK, (7) final check around the vehicle, etc. Accident risk locations during loading and unloading operations of the vehicle 300 depicted in the illustration for this operation are, for example, the ratchet associated with operations (2) and (6) and the manhole hatch associated with operations (3) to (5).

[0056] 8, the second in-vehicle information 130 is, for example, safety operation standard information assuming an operation in which a hose mounted on a tank of the vehicle 300 is connected to a silo and powder in the tank is poured into the silo, and is textual information such as (1) ratchet, (2) after hose connection, PTO (on), (3) start of pressure transfer, end of pressure transfer, (4) after PTO (off), hose retraction, (5) hose retraction successful, (6) ratchet retraction successful, (7) final check around the vehicle, etc. Accident risk locations during loading and unloading operations of the vehicle 300 depicted in the illustration for this operation are, for example, the ratchet related to operations (1) and (6) and the hose related to operations (2) to (5).

[0057] The vehicular signboard 2 further includes a first fixing device 125 and a second fixing device 126. The first fixing device 125 fixes the second surface 122 and the second interior surface 124, which are concealed in the first state, to expose the first interior information display unit 127. The second fixing device 126 fixes the first surface 121 and the first interior surface 123, which are concealed in the second state, to expose the second interior information display unit 128. The first fixing device 125 is, for example, a pair of magnets provided on the second surface 122 and the second interior surface 124. The second fixing device 126 is, for example, a pair of magnets provided on the first surface 121 and the first interior surface 123.

[0058] It is sufficient to provide at least one of the first fixing device 125 and the second fixing device 126. In other words, there is no need for a fixing device that fixes the state in which the displacement portion 120 hangs below the main body 100 via the ring 134. On the other hand, a fixing device that fixes the state in which the displacement portion 120 exists above the main body 100 via the ring 134 is necessary.

[0059] There may be provided a plurality of displacement portions 120. In this example, a plurality of displacement portions 120 may be threaded through the ring 134.

[0060] According to this embodiment, it is possible to post safety operation standards that are tailored to the content of the loading and unloading work.

[0061] III. Third Embodiment

[0062] FIG. 9 shows a vehicle signboard according to a third embodiment of the present disclosure.

[0063] The vehicular signboard 3 further includes an opening / closing section 140 in addition to the configuration of the vehicular signboard 1 of the first embodiment or the vehicular signboard 2 of the second embodiment.

[0064] The opening / closing unit 140 is a plate made of a durable material such as plastic, and has, for example, a rectangular shape in a plan view. The size of the opening / closing unit 140 is equal to or smaller than the size of the main body 100. The opening / closing unit 140 is provided at the front end 107 of the main body 100 so as to be openable and closable. The opening / closing unit 140 can be opened and closed using the front end 107 of the main body 100 as a fulcrum. The mechanism that enables opening and closing is not limited. In this example, a plurality of openings 143 are provided at the front end 107 of the main body 100, and a corresponding plurality of openings 142 are provided near one end of the opening / closing unit 140. The openings 142 of the opening / closing unit 140 and the openings 143 of the main body 100 are passed through a ring 144. The opening / closing unit 140 can be opened and closed via the ring 144.

[0065] When bending portion 200 is hung on power window 302, opening / closing portion 140 opens to the front side of vehicle 300. As a result, compared to a structure without opening / closing portion 140, when opening / closing portion 140 is closed, main body 100 remains the same size without increasing in size, and main body 100 can hide a larger portion of side mirror 304 of driver's seat 301 as seen by the driver in driver's seat 301.

[0066] The opening 106 may be inclined so that it is lower near the front end 107 and higher near the rear end 108. When the bent portion 200 is hung on the power window 302, the main body 100 is positioned closer to the front of the vehicle 300, and the opening / closing portion 140 is more likely to open under its own weight.

[0067] IV. First Application Example

[0068] For example, if vehicle 300 is a passenger car, the in-vehicle information 111 may display information on standard actions that the driver should take in the event of an accident, disaster, or emergency, lifesaving information such as artificial respiration, and contact information such as a telephone number. The outside-vehicle information 112 may display a message to be conveyed to pedestrians, family, acquaintances, etc. outside the vehicle (e.g., "Emergency, temporarily evacuate!") and emergency contact information. Vehicle signs having such in-vehicle information 111 and outside-vehicle information 112 are beneficial to everyone. For example, by distributing vehicle signs as novelty goods when purchasing vehicle 300, when undergoing vehicle inspection, or when issuing and renewing a driver's license, the in-vehicle information 111 and outside-vehicle information 112 can be provided to many drivers. Furthermore, proper use of the vehicle signs can help prevent accidents caused by sudden acceleration of vehicle 300, etc.

[0069] FIG. 10 shows a vehicle sign according to a first application example of the present disclosure.

[0070] As shown in (A), the vehicle signboard 4 is composed of, for example, a translucent clear file 400. The clear file 400 functions as the main body 100 and the bending portion 200. A U-shaped (i.e., three-sided rectangular) perforation 402 is formed on one side 401 (the vehicle interior surface 101 of the main body 100) of the clear file 400. The U-shaped perforation 402 includes a perforation near the closed short side 403 of the clear file 400 and two perforations parallel to the long sides 404, 404. No perforations are provided at a connection portion 406 near the open short side (the upper side 109 of the main body 100) of the clear file 400. The bending portion 200 is the rectangular portion defined by the U-shaped perforation 402. The main body 100 is the portion excluding the bending portion 200.

[0071] A sheet 405 containing information (in-vehicle information 111) for the driver to take in an emergency, such as emergency response procedures, is inserted into the clear file 400. The in-vehicle information display unit 103 that displays the in-vehicle information 111 is preferably positioned on the lower side including the perforation 402, rather than on the upper portion 105 above the area of ​​the perforation 402 (on the open short side) of the clear file 400. The in-vehicle information 111 is visible through one side 401 of the clear file 400. The clear file 400 with the sheet 405 inserted can be distributed as a vehicle sign as a novelty item when purchasing a vehicle 300, when undergoing vehicle inspection, or when issuing or renewing a driver's license.

[0072] As shown in (B), when using the clear file 400 as a vehicle signboard 4, the user (driver) separates the bent portion 200 from the main body 100 by cutting the U-shaped perforation 402. The bent portion 200 is bent at the connecting portion 406 so that the bent portion 200 covers the upper side 109 of the main body 100.

[0073] As shown in (C), the bending portion 200 is bent. Specifically, the bending portion 200 is bent so that the vehicle interior surface 101 (surface 401 with perforations 402) side of the main body 100 becomes the outer arc surface 201, and the vehicle exterior surface 102 side becomes the inner arc surface 202. The back surface of the clear file 400 functions as the vehicle exterior surface 102 of the main body 100. The vehicle exterior information display unit 104 is provided on the vehicle exterior surface 102 and displays vehicle exterior information 112 (in this example, "Emergency, temporarily evacuating!") to people outside the vehicle 300. When the bending portion 200 is configured in a bent shape, it does not face at least a portion (most part) of the vehicle exterior information display unit 104. Typically, when the bending portion 200 is configured in a bent shape, it does not face the entire vehicle exterior information display unit 104.

[0074] V. Other Applications

[0075] The shape of the upper part of the power window 302 varies depending on the vehicle model, but the flexible and malleable bending portion 200 allows it to be adapted to various vehicle models. Since it can be easily installed not only on the power window 302 but also on similar shapes, it can be used for a variety of purposes.

[0076] Furthermore, by changing the in-vehicle information 111 and the outside-vehicle information 112, it is possible to apply the information to cases where the in-vehicle information 111 and the outside-vehicle information 112 are not information on safety operation standards for loading and unloading operations of special vehicles, etc. For example, if the vehicle 300 is a logistics delivery vehicle, the in-vehicle information 111 may display information on safety operation standards for loading and unloading operations, and the outside-vehicle information 112 may display text information about delivery operations and illustrations of brakes and other items that require attention.

[0077] This technology is expected to contribute to the achievement of Goal 9 of the SDGs (Sustainable Development Goals), "Build resilient infrastructure, promote inclusive and sustainable industrialization," and Goal 3, "Ensure healthy lives and promote well-being for all."
