Description

[Technical Field]

[0001] The present invention relates to a greeting sign display device for motorcycles that allows riders to exchange greeting signs such as "YAEH" when passing each other on motorcycles (two-wheeled motor vehicles). [Background technology]

[0002] For example, when riders pass each other while touring motorcycles, they are known to exchange hand signs (greeting signs) such as a peace sign, commonly referred to as "YAEH!", as a greeting to convey their wishes for safety on the road, a shared sense of camaraderie, and a welcoming feeling (e.g., Non-Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0003] [Non-Patent Document 1] [Retrieved October 15, 2025], Internet<URL:https: / / www.8190.jp / bikelifelab / useful / beginners / yaeh / 、バイクのヤエーとは?> DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] However, if you make the "Ya-ee" gesture while riding a motorcycle, you will inevitably be riding with one hand, which could lead to an accident. The risk of riding with one hand increases especially in bad weather such as heavy rain or strong winds, or when there is no light in a tunnel or at night, so even when passing an oncoming vehicle, the "Ya-ee" gesture is not made out of safety in order to prioritize safety.

[0005] Also, depending on the weather and sunlight conditions, the "Ya-e" signal may not be conveyed properly. For example, drivers may raise one hand to adjust their helmet position while driving or to operate an intercom (a walkie-talkie with a headset) or camera, so the signal may not necessarily be conveyed as "Ya-e" to the other person.

[0006] As a result of intensive research, the inventor discovered that all of the above-mentioned problems could be solved if, when two motorcycle riders pass each other, they operated a switch operating unit on the handlebars or the like, causing an electronic display unit attached to the motorcycle to illuminate a greeting sign (including greeting letters such as "YAEH"), and thus completed the present invention.

[0007] In other words, the present invention has been developed in consideration of these problems, and aims to provide a greeting sign display device for motorcycles that can display greeting signs (including greeting text) that are more visible than hand signals to other riders while riding, without the rider having to take their hands off the handlebars, even in high-risk environments such as bad weather or at night. [Means for solving the problem]

[0008] The invention described in claim 1 comprises a dustproof and waterproof electric light display unit that is attached to a motorcycle and displays a greeting sign (including greeting text) to a rider while riding, and a switch operation unit that is provided around the handlebars of the motorcycle and instructs the electric light display unit to display the greeting sign. The greeting sign display device for a motorcycle is characterized by comprising a control means for receiving a display instruction signal from the switch operation unit and displaying the greeting sign on the electronic display unit based on this signal.

[0009] The term "motorcycle" here refers to motorized bicycles, regular motorcycles, and large motorcycles under the Road Traffic Act. The term "rider in motion" here refers not only to the driver of another motorbike passing your own motorbike in the oncoming lane, but also to the driver of another motorbike traveling behind your own motorbike. The type of greeting sign is arbitrary. For example, a hand wave (emoticon), peace hand (emoticon), good hand (emoticon), clasped hands (emoticon), or a smile (emoticon) can be used. Other greeting characters such as "YAER" or "Ya-e" are also acceptable. The emoticon and the character may be displayed simultaneously or with a time lag.

[0010] The greeting text may be in any language. For example, the control means may be configured to allow the language to be switched by operating a switch on the switch operation unit. The type of display for the electric display unit is arbitrary, and may be, for example, an LED display, a liquid crystal display, an organic EL display, a light bulb display, or the like.

[0011] The position on the motorcycle where the electric light display unit is attached is arbitrary. For example, it may be on the front of the motorcycle, the rear of the motorcycle, or both. The electric light display unit may also be fixed integrally to the rear side of the rearview mirror (the side facing the direction of travel of the motorcycle) or may be connected in contact with the rearview mirror via a connecting member (for example, a screw). Alternatively, the electronic indicator may be disposed in front of the rearview mirror at a distance using, for example, a stay extending from around the handlebars. Also, the electronic indicator disposed in front of the rearview mirror at a distance using a stay may be hung on the rearview mirror (including a stay for the rearview mirror) via a fastener such as a hook.

[0012] In this way, if the electric display unit can be hung at a predetermined interval in front of the rearview mirror, it becomes possible to set the greeting sign by providing the confirmation display as described in claims 3 and 4 on the back side of the electric display unit. Also, if the electric display unit is located on the back side (front) of the rearview mirror, the electric display unit attached to the front of the motorcycle will not be too noticeable. The display surface may be any of the front and back surfaces of the electric display unit. For example, it may be only the front surface (for passing riders), only the back surface (for riders riding behind), or both.

[0013] The shape of the electric display unit is arbitrary. For example, it may be a circle, an ellipse, a triangle or a polygon with more sides, etc. It may also be in the shape of various animals or characters. The level of waterproofness and dustproofness is determined by the IP (Ingress Protection) standard (a standard established by the International Electrotechnical Commission), and a high protection rating of IP54 or higher, especially IP65 or IP67, is preferred. As a member for attaching the electric display unit to the motorcycle, for example, various types of stays can be used. Furthermore, as an attachment member for retrofitting, a stay with a clamper attached to the base that can be detachably connected to a predetermined location on the motorcycle is preferable.

[0014] The type of switch operating unit is also arbitrary, and examples include a push switch, a toggle switch, a rocker switch, a slide switch, a rotary switch, and a voice switch. The switch operation unit may be mounted directly on the steering wheel or near the steering wheel. Since there are many existing standard switches around the steering wheel, it is necessary to install it in a location that is easy to press and does not get in the way. In Japan, where vehicles drive in the left lane, the left steering wheel is where the passing button, high / low light switch button, turn signal button, and hazard button are concentrated. Therefore, it is preferable to place the switch operation unit in a location where it can be operated with the index finger on the right steering wheel (such as the passing button position on the left steering wheel).

[0015] The switch operation unit is connected to the electric light display unit by wire or wirelessly. The voice switch may be, for example, a device in which a microphone is attached to a helmet and the voice picked up by the microphone is used as the switch. Specifically, the device may be configured to include a microphone that converts ambient sounds into electrical signals, and signal processing means that receives the electrical signals from the microphone as input, generates a signal to instruct the display of a greeting sign when a predetermined voice pattern is detected, and transmits this to control means.

[0016] The control means may, for example, be one having a central processing unit (CPU) as the main body, a memory unit (ROM (Read Only Memory), RAM (Random Access Memory)) that stores display data for the greeting sign, and display logic that reads the display data for the greeting sign from the memory unit and displays it on the electronic display unit. The power source of the motorcycle greeting sign display device is not limited, and may be a battery or any type of battery.

[0017] In addition, since the rider (the rider who operated the switch) does not know whether the greeting sign is displayed electronically on the electronic display unit when the switch operating unit is operated, an illuminating notification means may be provided that notifies the rider of the electronic display by sound or light, for example. In addition, a greeting lamp or the like may be provided on the rear of the motorcycle to notify the rider who has just passed that a greeting signal has been sent when passing.

[0018] Furthermore, the invention described in claim 2 is the motorcycle greeting sign display device according to claim 1, characterized in that the display of the electric light display unit is any one of an LED display, a liquid crystal display, and an organic EL display, and the control means has a storage unit that stores display data for the greeting sign, and display logic that reads the display data for the greeting sign from the storage unit based on a display instruction signal from the switch operation unit, and uses this display data to display the greeting sign on the electric light display unit.

[0019] The invention described in claim 3 is such that the display surface of the electric light display unit is the front surface, and the electric light display unit is attached to the front of the motorcycle, and the memory unit stores at least one of the display data of the plurality of greeting signs, the color data of the plurality of greeting signs, the light emission pattern data of the plurality of greeting signs, and the light emission time data of the plurality of greeting signs, and the back side of the electric light display unit is provided with a sign selection button for selecting a desired greeting sign from the display data of the plurality of greeting signs, a color selection button for selecting a desired greeting sign from the color data of the plurality of greeting signs, and a button for selecting a desired greeting sign from the light emission pattern data of the plurality of greeting signs. and a light emitting time selection button for selecting a desired one from a plurality of light emitting time data for the greeting sign, and a confirmation display is provided on the back of the electronic display unit for displaying the greeting sign that reflects at least one of the greeting sign selected by the sign selection button, the color selected by the color selection button, the light emitting pattern selected by the light emitting pattern selection button, and the light emitting time selected by the light emitting time selection button when setting up the display of the greeting sign.

[0020] The color of the emitted light is arbitrary, and examples include white, yellow, blue, pink, purple, and green. The light emission pattern is arbitrary. For example, it may be a steady light or a flashing light. Alternatively, the greeting sign (including text) may flow horizontally, vertically, diagonally, or the like. The light emission time is arbitrary, and may be, for example, 1 second, 3 seconds, or 5 seconds. The button here refers to various switches (including those for touch panels). The type of confirmation display is not limited, and may be, for example, an LED display, a liquid crystal display, an organic EL display, or the like. The size and shape of the confirmation display are also arbitrary.

[0021] The invention described in claim 4 is the motorcycle greeting sign display device described in claim 3, characterized in that the electronic display unit is attached to the front of the motorcycle, the memory unit stores the greeting signs that have been changed by operating at least one of the sign selection button, the color selection button, the light pattern selection button, and the light duration selection button, and the display logic is simultaneous display logic that reads out display data for the greeting signs including the changed ones from the memory unit based on a display instruction signal from the switch operation unit, and uses this display data to simultaneously display the greeting signs on the electronic display unit and the confirmation display.

[0022] The invention described in claim 5 is a motorcycle greeting sign display device described in claim 1 or claim 2, characterized in that the electronic display unit is fixed (including embedded) integrally to the back of the rearview mirror, or hung in a contacting or separated state via a hanging device. The electric display unit may be fixed (including embedded) integrally to the rear of the rearview mirror, or may be hung in a contacting or separate state from the rear of the rearview mirror using various fasteners (e.g., hooks, connecting arms, screws, double-sided tape, hook-and-loop fasteners, etc.). [Effects of the Invention]

[0023] With the motorcycle greeting sign display device of the present invention, for example, when two motorcycle riders pass each other, the user (motorcycle rider) operates a switch operating unit located around the handlebars. When the control means receives a display command signal from this switch operating unit, the control means causes a greeting sign containing greeting text to be displayed on the electronic display unit. This allows riders to display highly visible greeting signs (including greeting text) to other riders without taking their hands off the handlebars, even in high-risk environments such as bad weather or at night. Furthermore, the electric display unit is dustproof and waterproof, so that rain while driving, water and condensation when washing the car, and sand, dust, soil, fine particles, etc. kicked up while driving can be prevented from entering the inside of the electric display unit.

[0024] In particular, according to the present invention as set forth in claim 2, when the control means receives a display instruction signal from the switch operation unit, it reads out the display data of the greeting sign (including greeting characters) stored in the memory unit based on a command from the display logic, and using this read display data, the greeting sign is displayed on an electronic display unit consisting of either an LED display, a liquid crystal display, or an organic EL display.

[0025] According to the present invention as set forth in claim 3, the back side of the electronic display is provided with at least one of a sign selection button, a color selection button, a light pattern selection button, and a light duration selection button, as well as a confirmation display. This allows the user to check and adjust the display content while sitting on the motorcycle, without having to move to the front of the electronic display when setting the greeting sign, making it easy to set the greeting sign display. Furthermore, since the electric display unit and the confirmation display are integrated, the overall device can be made compact.

[0026] Furthermore, according to the present invention as set forth in claim 4, when the control means receives a display instruction signal from the switch operation unit, based on a command from the simultaneous display logic, the corresponding greeting sign is simultaneously displayed on the front display surface of the electronic display unit attached to the front of the motorcycle and on the confirmation display on the back of the electronic display unit, based on the display data of the greeting sign including the changed greeting sign (changed greeting sign) read from the memory unit.

[0027] As a result, by looking at the confirmation display when operating the switch operation unit, the user can know in real time whether the greeting sign (including the changed greeting sign) from the electronic display unit has been sent to the other rider. Moreover, because the same greeting sign is displayed on the electronic display unit and the confirmation display, the user can visually confirm while driving whether the greeting sign sent to the other rider is the desired one, and if for some reason an unintended greeting sign is displayed, or if the user determines that the displayed greeting sign is not suitable for the environment around the road they are currently traveling on, they can stop the vehicle immediately and change to the desired sign.

[0028] Furthermore, the invention described in claim 5 is that the rearview mirror is a place that does not need to be in the field of view of the motorcycle rider at all times. Therefore, unlike when the electric display unit is simply attached to the handlebars via a stay or the like, the electric display unit does not obstruct the driver's field of view at all. Furthermore, since the electronic display unit is fixed (including being buried) to the back of the rearview mirror, or is hung in a contacting or spaced-apart state in front (behind) of the rearview mirror via a fastener, the electronic display unit can be installed on the motorcycle without compromising the exterior design of the motorcycle.

[0030] An embodiment of this invention will be described in detail below. Here, we will take as an example a device for sending a greeting signal of "YAEH" to other riders when they pass each other on their bikes. [Example]

[0031] In Figures 1 and 2, 10 is a motorcycle greeting sign display device according to a first embodiment of the present invention. This motorcycle greeting sign display device 10 is equipped with a dustproof and waterproof electronic display unit 12 that is attached to a motorcycle 11 and displays a greeting sign (including greeting text) to a rider while riding, a switch operation unit 14 that is provided around a handlebar 13 of the motorcycle 11 and instructs the electronic display unit 12 to display the greeting sign, and control means 15 that receives a display instruction signal from the switch operation unit 14 and causes the electronic display unit 12 to display the greeting sign based on this signal.

[0032] These parts will be specifically described below. The electric display unit 12 is a battery-chargeable electronic device with a protection rating of IP67 that is highly dustproof and waterproof, and has a long stay 17 that is detachably connected near the base of the grip 16 on one side (the right side) of the handlebars 13, and a large-diameter disk-shaped casing 18 at the tip of the stay 17. An LED display (display) 19 is provided over almost the entire front side of the casing 18 to display a greeting sign to other riders while riding.

[0033] The electronic display unit 12 is arranged at a distance via a stay 17 on the rear side of the rearview mirror M (on the side in the traveling direction of the motorcycle 11). If it is arranged on the rear side of the rearview mirror M, the electronic display unit 12 attached to the front of the motorcycle 11 will not be too noticeable. The electronic display unit 12 may also be directly embedded on the rear side of the rearview mirror M (see the dashed line in Figure 2). Alternatively, although not shown, for example, a hook (hanging device) extending from the stay 17 may be hooked onto the arm of the rearview mirror M, and the electronic display unit 12 may be arranged in front of the rearview mirror M in a contacting or separated state.

[0034] As shown in FIG. 3, an oval rectangular LED confirmation display 20 is provided at the upper back of the electronic display unit 12, which displays the same greeting sign as that displayed on the LED display 19. Meanwhile, at the lower back of the electronic display unit 12, a sign selection button 21 for selecting a desired greeting sign from among a plurality of display data for greeting signs, a color selection button 22 for selecting a desired greeting sign from among a plurality of color data for greeting signs, a light emission pattern selection button 23 for selecting a desired greeting sign from among a plurality of light emission pattern data for greeting signs, and a light emission time selection button 24 for selecting a desired greeting sign from among a plurality of light emission time data for greeting signs are arranged in a horizontal row at a predetermined interval.

[0035] There are seven types of greeting signs: hand gesture (emoji), peace hand (emoji), good hand (emoji), clasped hands (emoji), smile (emoji), YAER (letter), and YAEE (letter). There are six colors available: white, yellow, blue, pink, purple, and green. There are four types of lighting patterns: steady, flashing, horizontal flow, and vertical flow. There are three lighting durations: 1 second, 3 seconds, and 5 seconds. It should be noted that confirmation display 20 may not display the same greeting sign as LED display 19, but may instead display the details of the change using characters, icons, etc.

[0036] Furthermore, as shown in the block diagram of Figure 4, the control means 15 has a central processing unit (CPU) 25, a memory unit 26 housed in the casing 18 of the electronic display unit 12 and storing display data for a plurality of greeting signs (including standard greeting signs set at the time of shipment from the factory), a plurality of color data for the greeting signs, a plurality of light-emitting pattern data for the greeting signs, and a plurality of light-emitting time data for the greeting signs, a display change logic 27 that displays a modified greeting sign reflecting changes on the confirmation display 20 based on the display data, color data, light-emitting pattern data, and light-emitting time data for the greeting signs selected by pressing each of the selection buttons 21 to 24, and a simultaneous display logic (display logic) 28 that reads out the display data for the greeting signs (including the modified greeting signs) from the memory unit 26 based on a display instruction signal from the switch operation unit 14, and uses this display data to simultaneously display the corresponding greeting sign on the electronic display unit 12 and the confirmation display 20.

[0037] 2, the switch operation unit 14 is a push-type switch fixed to a position on the right side of the handlebar 13 where it can be operated with the index finger. The switch operation unit 14 may also be provided near a handlebar switch box on the left side of the handlebar 13. The power source for this switch operation unit 14 is a button battery, and a display instruction signal from the switch operation unit 14 is transmitted to the control means 15 wirelessly.

[0038] Next, the control system of the motorcycle greeting sign display device 10 will be specifically described with reference to the block diagram of FIG. An input port of the central processing unit 25 of the control means 15 is connected to the switch operation unit 14, the memory unit 26, the sign selection button 21, the color selection button 22, the light emission pattern selection button 23, the light emission time selection button 24, a display change logic 27 that displays a changed greeting sign on the confirmation display 20 based on the display data, color data, light emission pattern data, and light emission time data of the greeting sign selected by pressing these buttons, and a simultaneous display logic 28. Meanwhile, an LED display 19 and a confirmation display 20 are connected to an output port of the central processing unit 25.

[0039] Next, a method of using the motorcycle greeting sign display device 10 of the present invention will be described with reference to FIGS. Set the greeting sign before riding the Bike 11. Note that this operation is not necessary if you are happy with the standard greeting sign set at the factory.

[0040] As shown in Figures 3 and 4, when setting a greeting, the user looks at confirmation display 20 and presses sign selection button 21, color selection button 22, light-emitting pattern selection button 23, and light-emitting time selection button 24, which are located on the back of electronic display unit 12, as appropriate, to determine the desired greeting sign. That is, each time a corresponding button is pressed, display change logic 27 displays a different greeting sign, color, light-emitting pattern, and light-emitting time on confirmation display 20. By repeating this operation, the desired greeting sign is finally determined. The determined greeting sign is stored in memory unit 26 as a changed greeting sign based on a command from display change logic 27.

[0041] In this way, the sign selection button 21, color selection button 22, light emitting pattern selection button 23, light emitting time selection button 24, and confirmation display 20 are arranged on the back side of the electronic display unit 12. Therefore, when setting the greeting sign, the user can check and adjust the display content while remaining seated on the seat of the motorcycle 11, without having to move to the front side of the electronic display unit 12, making it easy to set the greeting sign display. Furthermore, since the LED display 19 of the electric light display unit 12 and the confirmation display 20 are integrated, the overall device can be made compact.

[0042] During touring, when a motorcycle 11 approaches from the oncoming lane and the riders pass each other, the user operates a switch operation unit 14 located around the handlebars 13, which sends a display instruction signal to the control means 15. When the control means 15 receives this signal, it reads display data for the modified greeting sign (which may be a standard greeting sign) from the memory unit 26 based on a command from the simultaneous display logic 28, and based on this display data, it causes the corresponding greeting sign to be simultaneously displayed on the LED display 19 on the front side of the electric display unit 12 attached to the front of the motorcycle 11 and on the confirmation display 20 on the back side thereof.

[0043] This allows the rider to display a highly visible greeting sign (including greeting text) to other riders by emitting light without taking their hands off the handlebars 13, even in high-risk environments such as bad weather or at night. Furthermore, the electric light display unit 12 is dustproof and waterproof, so that rain while driving, water and condensation during car washing, and sand, dust, soil, fine particles, etc. kicked up while driving can be prevented from entering the inside of the electric light display unit 12.

[0044] Furthermore, since the corresponding greeting sign is simultaneously displayed on the LED display 19 on the front side of the electronic display unit 12 and on the confirmation display 20 on the back side thereof, the user can know in real time whether the greeting sign (including the greeting sign whose display has been changed) from the electronic display unit 12 has been sent to the other rider by looking at the confirmation display 20 when operating the switch operation unit 14.

[0045] Furthermore, since the same greeting sign is displayed on the electronic display unit 12 and the confirmation display 20, the user can visually confirm while driving whether the greeting sign sent to the other rider is the desired one. If for some reason the greeting sign sent is an unintended one, or if the user determines that the displayed greeting sign is not suitable for the environment around the road they are currently traveling on, they can stop immediately and change to the desired sign.

[0046] Here, the greeting sign is displayed on both the LED display 19 and the confirmation display 20 using the simultaneous display logic 28, but this is not limited to this, and it may also be displayed only on the LED display 19 using display logic not shown. A button for adjusting the brightness of the greeting sign may be provided on the back side of the electric display unit 12. Alternatively, the brightness may be automatically adjusted according to the sunlight conditions. Furthermore, the switch operation unit may be changed from a push-button switch (not shown) to a voice switch type in which a microphone is attached to the helmet and a display instruction signal is transmitted by the sound picked up by the microphone. A specific configuration may include a microphone that converts ambient sound into an electrical signal, and signal processing means that receives the electrical signal obtained from the microphone as an input, generates a display instruction signal for a greeting sign when a predetermined voice pattern is detected, and transmits this to control means. [Industrial Applicability]
