Description

  The present invention is used by attaching to a wheel so that a nearby pedestrian including a hearing-impaired person and an amblyopic person can recognize the approach of a hybrid vehicle or an electric vehicle, which is pointed out as dangerous because the driving sound is too quiet. The present invention relates to a wheel travel recognition display sheet.

  Conventionally, when a hybrid vehicle (HV) or an electric vehicle (EV) is driven by using only an electric motor as a power source, the running sound is quiet, only the frictional noise between the tire and the road surface and the sound of the vehicle body cutting the wind. Become. In particular, since the vehicle is driven by an electric motor when starting or when traveling at a low speed of 20 km / h or less, no engine sound is emitted from the vehicle. The volume level at the time of departure is 50 dB or more in a general car, whereas it is very small, 30 dB or less, which is about “person whispering” in a hybrid car. For this reason, voices fearing the occurrence of an accident have been raised as “not noticed at all” even when the hybrid vehicle approaches from hearing impaired people, low vision people, and healthy people.

  In response to this, the Ministry of Land, Infrastructure, Transport and Tourism formulated a guideline for the installation of a static running warning device that outputs an artificial sound for warning at the review committee, and actively developed the static running warning device and vehicle It is urged to be installed. In this guideline, it is a sound reminiscent of the driving situation of a car such as a pseudo engine sound (that is, it is not a chime or melody sound), the volume is the same level as a general engine sound, up to 20 km / h from the start Standards such as the traveling speed of the vehicle and the fact that an alarm sound is automatically output during reverse travel are incorporated. This is the world's first effort to go against modern technological developments that try to reduce the driving noise of automobiles.

  On the other hand, as such a pseudo engine sound generating apparatus, there is one disclosed in Patent Document 1, for example. This pseudo engine sound generating device includes a sound generating unit including an amplifier and the like, and a sound signal from the sound generating unit is supplied to a sound output unit such as a speaker via a switch. It is provided on the vehicle body side. And in the mode which is drive | working only with the motive power of an electric motor, the sound signal from a sound generation part can be sent to a sound output part by operating the said switch manually. Further, based on the sound signal, the speaker outputs a pseudo engine sound similar to the engine sound, can alert a pedestrian outside the vehicle that the vehicle is approaching, and can recognize a nearby pedestrian or the like. .

  However, in such a pseudo engine sound generation device, only when the driver operates a switch near the dashboard, the pseudo engine sound is output from the speaker, so unless the switch is operated, For example, when the driver has inadvertently forgotten to operate the switch, there is a risk of causing an accident because a warning is not issued even when the pedestrian is traveling on a crowded road. Therefore, there is a disadvantage that the intended purpose of the alarm equipment prepared cannot be achieved because the hybrid vehicle and the electric vehicle are too quiet and dangerous. In addition, the electric circuit parts such as the switch and the sound generating unit are not preferable because they are installed in the passenger compartment, which increases the system size and size, and further promotes battery consumption. On the other hand, even a hearing-impaired person or a hearing-impaired person can visually recognize the approach of a car or the like if his / her vision is normal.

  However, on a dimly lit road such as early morning or at sunset, not only deaf and weak-sighted people but also healthy people may not be able to recognize a vehicle approaching quietly. For example, it is difficult to recognize a car that makes a left turn from a side road to a main road and crosses a pedestrian crossing. Even if the headlamps are lit, the headlamps are facing the road (the headlamps are not facing the pedestrian side), so the pedestrian side may not be able to see the car immediately. Pedestrians trying to cross a pedestrian crossing may be at risk.

  In addition to hearing-impaired and weak-sighted people, whether general pedestrians and children are traveling, stopping, accelerating, or decelerating, for example, near a stop line such as an intersection There is a risk that it may not be possible to judge, and there is a risk that walking into the pedestrian crossing at the intersection will be started by mistake.

  In the present invention, as described above, the driving state of a car can be immediately emitted from a wheel to a hearing-impaired person, a weakly-sighted person, and a pedestrian who is walking in the vicinity of the car. An object of the present invention is to provide a wheel travel recognition display sheet that can avoid personal injury by making it recognize by light.

  In order to achieve the above-described object, the wheel travel recognition display sheet according to the present invention can be attached to the surface of an automobile wheel or a tire mounted on the wheel, and a phosphorescent pigment is mixed or applied thereto. It consists of a sheet.

  According to this configuration, the sheet in which the phosphorescent pigment is mixed or applied has the property of releasing the light energy stored by the phosphorescent pigment in the daylight (sunlight) or electric light in the dark or at night. By the way, when it sticks to a wheel or a tire, it makes it easy for a pedestrian to recognize this rotation of a wheel or a tire by reflection of light. Therefore, it is possible for the pedestrian to easily recognize whether or not the vehicle having the wheel is traveling, and further whether the vehicle is accelerating or decelerating. Therefore, on the basis of such wheel behavior determination, a pedestrian can easily determine whether or not to continue walking, and whether or not to start walking. It is possible to prevent a normal healthy person from encountering a personal accident.

  In this case, when a pressure-sensitive adhesive is applied to one side of the sheet mixed with or coated with a phosphorescent pigment, and the sheet is detachably attached to the release paper via the pressure-sensitive adhesive, the release paper It is possible to easily form a light reflecting portion by a phosphorescent pigment on the wheel or tire by peeling the sheet from and sticking the sheet to the surface of the wheel or tire via the adhesive applied thereto. it can.

  In addition, the seat can be closely attached to the wheel or tire by forming a shape that matches the shape of the wheel or tire, so that the seat is removed from the rotating wheel or tire exposed to wind and rain. Inadvertent peeling can be avoided.

  The sheet is a belt-like sheet, and the belt-like sheet is provided with a plurality of notches at predetermined intervals in the longitudinal direction. As a result, the belt-like sheet that rotates together with the wheels while the automobile is running forms reflective portions by phosphorescent pigments and non-reflective portions corresponding to the notches on the wheels (wheels and tires) alternately, so that the light flashes. The effect. From this light reflection state, it is possible to make a pedestrian clearly see whether the automobile is stopped or traveling, or whether the vehicle is accelerating or decelerating.

  Furthermore, when the sheet is formed of a plastic sheet, it can be manufactured by mixing a phosphorescent pigment into the resin raw material, so that it is easy to manufacture, does not corrode, and has weather resistance, so it can withstand long-term use. preferable.

  According to the present invention, it is not limited to a hearing impaired person or a low vision person by observing the behavior of a wheel or a tire when a hybrid vehicle or an electric vehicle is approaching, accelerating or decelerating to a pedestrian, and a healthy person. Can also be surely recognized.

  The present invention has been briefly described above. The best mode for carrying out the invention described below will be described in detail with reference to the accompanying drawings.

It is a front view which shows the wheel by which the driving | running | working recognition display sheet for wheels by embodiment of this invention was stuck. FIG. 2 is a front view of the wheel travel recognition display sheet shown in FIG. 1. It is a front view of the deformation | transformation state of the driving | running | working recognition display sheet for wheels shown in FIG. It is sectional drawing of the laminated structure of the driving | running | working recognition display sheet for wheels shown in FIG. It is sectional drawing which shows other embodiment of the driving | running | working recognition display sheet for wheels. It is a front view which shows the driving | running | working recognition display sheet for wheels by other embodiment of this invention. It is a front view which shows the driving | running | working recognition display sheet for wheels by other embodiment of this invention.

  A wheel travel recognition display sheet according to an embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 is a front view showing a wheel 11 of an automobile, and the wheel 11 has a known form in which a tire 13 is attached to a wheel 12. Some wheels 12 are equipped with a wheel cap for concealing the rim of the wheel 12. A wheel travel recognition display sheet 1 formed of a sheet 2 mixed or coated with a phosphorescent pigment is attached to the surface (front surface) of the wheel 12.

  As shown in FIG. 2, the wheel travel recognition display sheet 1 is provided with a plurality of notches 3 in a zigzag manner at substantially equal intervals on one side in the width direction of a sheet 2 that forms a belt-like body having a predetermined length as a whole. ing. These notches 3 have a triangular shape, and at the deepest position 3a of the triangular notches 3, only a few millimeters remain with respect to the straight edge on the side where the notches 3 are not provided in the width direction of the sheet 2. It is a connected shape. In this example, the sheet 2 is formed of a plastic sheet. Therefore, although the wheel travel recognition display sheet 1 has a thin plastic sheet 2 as a base material, as shown in FIG. 3, the wheel travel recognition display sheet 1 is bent into a gentle arc shape as a whole ( Deformation).

  On the other hand, the wheel travel recognition display sheet 1 is distributed and sold integrally with the release paper before being attached to the wheel 12. As shown in FIG. 4, the wheel travel recognition display sheet 1 has a plastic sheet (protective sheet) 2 coated with a phosphorescent pigment 4 applied to a release paper 6 so as to be peelable through an adhesive 5. Made up of. Therefore, the plastic sheet 2 can be easily peeled from the release paper 6 together with the phosphorescent pigment 4 and the adhesive 5. Further, the peeled plastic sheet 2 can be attached to the wheel 12 of the wheel 11 via an adhesive 5 as shown in FIG.

  Here, as the release paper 6, a high-quality paper or glassine paper coated with a plastic material such as a polyethylene layer or a polyvinyl alcohol layer and then coated with a silicone resin layer is used. In view of environmental load, useless type silicone resins are widely used today. The pressure-sensitive adhesive 5 is a pressure-sensitive adhesive mainly made of acrylic or special acrylic materials. For the plastic sheet 2, a water-resistant and weather-resistant resin sheet is used.

  Further, the phosphorescent pigment 4 is a pigment that emits phosphorescence for a relatively long time in the dark when irradiated with light of artificial lighting such as sunlight or electric light, and is called animal light pigment because it resembles charging and discharging of a storage battery. It is also used for safety sign boards. This phosphorescence is light having a longer wavelength than that of the excitation light. However, the phosphorescence has a longer wavelength than that of fluorescence, has a long lifetime, and is superior to fluorescence in that light emission continues even when light irradiation is stopped. Luminescent pigments, such as zinc chloride and calcium chloride that have been specially treated, continue to emit light for a long time in the dark, but there are no particular restrictions on the materials used in this embodiment. For example, compounding agents such as aluminum oxide, strontium oxide, dyspodium oxide, eurobium oxide, boric oxide and calcium oxide can be exemplified.

  The running recognition display sheet for wheels in this form peels the adhesive 5 together with the phosphorescent pigment 4 and the plastic sheet 2 from the release paper 6 and extends over the surface (front surface) of the wheel 12 of the wheel 11 as shown in FIG. Can be pasted. The wheel travel recognition display sheet 1 adhered to the wheel 12 in this way is used for sunlight when the vehicle travels at night or at dusk, such as a tunnel or an underpass, at dawn or dusk. It emits phosphorescence by radiating the light energy accumulated in the phosphorescent pigment by receiving external light such as (sunlight) or electric light in the darkness. This phosphorescence is perceived by nearby pedestrians as intermittent light from the notch 3 as the wheel 11 rotates, so that the rotation of the wheel, that is, whether or not the vehicle is running can be reliably recognized.

  As described above, the wheel travel recognition display sheet 1 has the triangular cutouts 3 at equal intervals as shown in FIGS. 2 and 3, so that intermittent light clearly indicates the rotation of the wheel 11 during the rotation of the wheel 11. As a result, the visibility to the automobile is improved. Therefore, it is easier for pedestrians in darkness to determine the driving state of the car, that is, whether the car is stopped or running, and whether the car is accelerating or decelerating. The person can safely walk while measuring the positional relationship with the car.

  Note that the width and number of the notches 3 and the ratio of the notches 3 to the entire wheel travel recognition display sheet 1 are set to predetermined values that allow the change in the rotational speed of the wheels 11 to be determined. Those corresponding to the sizes of the tire 12 and the tire 13 are selected and attached to the surfaces of the wheel 12 and the tire 13, respectively.

  In order to improve the visibility of the rotation of the wheels 11, a plurality of rectangular cutouts 7 having a predetermined width may be provided on the wheel travel recognition display sheet 1A as shown in FIG. Further, as shown in FIG. 7, a plurality of fan-shaped wheel travel recognition display sheets 1B having a short overall length and notched are pasted on the surface of the wheel 12 or the tire 13 in an aligned state or in a random state. Even so, the visibility of the rotation of the wheel 11 can be sufficiently improved as described above.

  The wheel travel recognition display sheet 1 of the embodiment shown in FIG. 4 is shown when the phosphorescent pigment 4 is applied to the sheet 2, but this is manufactured by mixing the phosphorescent pigment as shown in FIG. The plastic sheet 2A may be used. According to this, since the sheet 2A can be manufactured by mixing the phosphorescent pigment into the resin raw material, it is easy to manufacture, and it is not necessary to apply the phosphorescent pigment. In addition, since it has weather resistance, it can withstand long-term use, which is preferable. Others are the same as those in the above embodiment, and the same components are denoted by the same reference numerals.

  As described above, in the present embodiment, the plastic sheet in which the phosphorescent pigment is mixed or applied can be pasted on the surface of the wheel 12 of the automobile or the tire 13 attached to the wheel 12 to thereby store the phosphorescent light. When the pigment is attached to the wheel 12 or the tire 13 from the place where the light energy stored by receiving the light of daylight or electric light is released to the darkness, the pedestrian is caused to rotate the wheel 12 or the tire 13. Becomes easier to recognize. In other words, it is easy to see whether a car is running, whether it is accelerating or decelerating, whether it is a deaf or visually impaired person, or a general pedestrian. Can be made. Therefore, based on the behavior determination of the automobile, the pedestrian can easily determine whether or not to stop walking and whether or not to change the walking direction.

  And the adhesive 5 is apply | coated to the single side | surface of the said plastic sheet 2 and 2A in which the luminous pigment was mixed or apply | coated, and the said plastic sheet 2 and 2A are stuck to the release paper 16 through this adhesive 5 so that peeling is possible. As a result, the plastic sheets 2 and 2A are peeled off from the release paper 6, and the plastic sheets 2 and 2A are joined to the surfaces of the wheel 12 and the tire 13 via the adhesive 5 applied thereto. By sticking, the phosphor 12 radiation portion by the phosphorescent pigment can be easily formed on the wheel 12 or the tire 13.

  By setting the wheel travel recognition display sheets 1, 1 </ b> A, 1 </ b> B to a shape suitable for the form of the wheel 12 or the tire 13, the wheel 12 or the tire 13 can be closely adhered (adhered) without any gaps. It is possible to reliably avoid the plastic sheets 2 and 2A from being peeled off from the wheel 12 and the tire 13 which are exposed to the rotation.

  The plastic sheet 2, 2A is a belt-like sheet, and a plurality of the belt-like sheets are attached to the wheels so as to be arranged at intervals, so that the light emission part (phosphorescence generation part) by the phosphorescent pigment and the gap Corresponding non-reflective portions are alternately obtained on the surface of the wheel 12, and therefore, an effect of flashing light when the wheel rotates can be obtained. This makes it possible for a normal pedestrian, including a visually impaired person or a visually impaired person with low vision, to clearly detect whether the car is stopped or running, or is accelerating or decelerating. , Can ensure the safety of pedestrians.

  The wheel travel recognition display sheet of the present invention enables the hearing impaired and the visual impairment by monitoring the behavior of the wheels and tires when the hybrid vehicle or the electric vehicle is approaching, accelerating or decelerating to a pedestrian. For wheels used on hybrid vehicles and electric vehicles that have the effect of being able to be recognized by not only low-sighted people but also healthy people, and the noise of running is too quiet. This is useful for a travel recognition display sheet.
