The plate member has an information display section that can display predetermined information by emitting light emitted from the light source upward.

According to the vehicle slope according to the above configuration, the light emitting portion that emits the light from the light source emits light from the left and right regions of the plate-like member (for example, the region to the left of the left end of the plate-like member or the region to the right of the right end of the plate-like member). By emitting the light, it is possible to make those in the vicinity of the vehicle ramp aware of the presence of the vehicle ramp and to indicate the position for the moving object to pass. Further, according to the vehicle slope having the above configuration, predetermined information can be displayed on the information display section by emitting the light emitted from the light source upward. Therefore, it is possible to further emphasize the presence of the vehicle ramp and the position for moving objects to pass through, and it is possible to inform the surroundings of the purpose of the vehicle ramp. For example, by displaying information on the information display section for allowing a person using a wheelchair to board the vehicle, the slope for the vehicle may be used for a person using a wheelchair to proceed toward the vehicle. You can let others know that you are.
Thus, according to the above configuration, it is possible to provide a vehicular slope that is more convenient for moving objects that use the vehicular slope.

Further, in the vehicle slope according to one aspect for achieving the above object,
The vehicle slope is configured to emit part of the light emitted from the light source toward the ground located below the plate-like member, and to make reflected light from the ground enter the lower surface of the information display section. It is composed of

According to the vehicle slope having the above configuration, a part of the light emitted from the light source is reflected on the ground located below the plate member and is incident on the lower surface of the information display section. Therefore, predetermined information can be displayed on the information display section with a simple configuration without using an optical member for making light incident on the information display section.

Further, in the vehicle slope according to one aspect for achieving the above object,
At least a part of the plate-like member including the information display section has a light guide section that guides the light emitted from the light source,
The light source is provided so that the emitted light enters the light guide section,
The light guiding section includes a reflecting section for reflecting the incident light so as to output it from the upper surface of the information display section.

According to the vehicle slope having the above configuration, the light emitted from the light source enters the light guide section, and then is emitted from the upper surface of the information display section by the reflection section included in the light guide section. Therefore, the utilization efficiency of the light emitted from the light source is increased, and the predetermined information displayed on the information display section can be displayed brightly.

Further, in the vehicle slope according to one aspect for achieving the above object,
The plate-like member is formed of a non-transparent member,
The information display section includes a light-transmitting section that is formed on the plate-like member and is capable of transmitting light emitted from the light source.

According to the vehicle slope having the above configuration, a member other than a transparent member such as a metal member can be used as the plate member. Therefore, the plate member can be made into a member with relatively high strength.

According to the present invention, it is possible to provide a vehicle slope that is more convenient for moving objects that use the vehicle slope.

Furthermore, in the description of this embodiment, for convenience of explanation, "passing direction" will be referred to as appropriate. The "passing direction" means that when the vehicle slope 2 (hereinafter simply referred to as "slope 2") is stretched between the door opening 11 and the road surface R, the moving body 3 is This is the direction of passing over the member 21 (the front-rear direction in FIG. 2).

(First embodiment)
A vehicle 1 equipped with a slope 2 according to a first embodiment will be described below with reference to FIGS. 1 to 3. In this embodiment, the vehicle 1 is a bus. However, the vehicle 1 is not limited to a bus, and may be another vehicle such as an ambulance, a taxi, a police car, or a one-box car.

As illustrated in FIG. 1 , the vehicle 1 includes a door opening 11 . The door opening 11 is provided on the side surface of the vehicle 1 and functions as an entrance for getting on and off the vehicle 1. Note that in this embodiment, the door opening 11 is in an open state. When the door opening 11 is in the open state, a passenger of the vehicle 1 can get on and off the vehicle 1 through the door opening 11.

A slope 2 may be installed at the door opening 11 of the vehicle 1 so as to span the door opening 11 and a road surface R near the door opening 11. When the slope 2 spans the door opening 11 and the road surface R, the mobile object 3 can get on and off the vehicle 1 by moving on the slope 2. Note that the mobile object 3 is, for example, a wheelchair, a kickboard, a bicycle, a small mobility device, a mobile robot, a pedestrian, or the like.

Next, the slope 2 will be explained with reference to FIGS. 2 and 3. FIG. 2 is a diagram of the slope 2 seen from above. FIG. 3 is a cross-sectional view taken along line AA in FIG. As illustrated in FIG. 2, the slope 2 includes a plate member 21, an edge 22, a light source 23, and a light emitting section 24. The plate-like member 21 is a thin plate-like member, and is rectangular in plan view. The plate member 21 may include, for example, a non-transparent member such as a metal member having relatively high material strength. Such a material is, for example, an aluminum profile. The plate-like member 21 includes a first part 21A, which is a front part of the plate-like member 21, and a second part 21B, which is a rear part of the plate-like member 21. The first part 21A is slightly larger than the second part 21B and can accommodate the second part 21B. The second part 21B can move in the front and back direction. The slope 2 enters the state illustrated in FIGS. 1 and 2 by moving the second portion 21B in the rearward direction from the state where the second portion 21B is accommodated in the first portion 21A.

In a state where the slope 2 is installed in the door opening 11, the plate member 21 functions as a passage for the moving body 3. The plate member 21 has an information display section 212.

The information display section 212 is configured to be able to display predetermined information such as a message for people near the slope 2. The information display section 212 has an arbitrary shape. The arbitrary shape is formed according to predetermined information. In this embodiment, the shape of the information display section 212 is the shape of an arrow with its tip facing forward and the shape of a wheelchair. The arrow indicates that the slope 2 is a slope for the moving body 3 riding on the vehicle 1. Further, the mark on the wheelchair indicates that the slope 2 is a slope for wheelchairs.

As illustrated in FIG. 3, the information display section 212 has a through hole 212a (an example of a transparent section). The through hole 212a is configured to transmit light.

As illustrated in FIGS. 2 and 3, the edge 22 is provided to the left of the left end of the plate member 21 or to the right of the right end of the plate member 21, respectively. The edge portion 22 is a thin and thin plate-shaped member extending in the front-rear direction. The vertical dimension of the edge 22 is larger than the vertical dimension of the plate member 21 (see FIG. 3).

The light source 23 is, for example, an LED (Light Emitting Diode). The light source 23 is configured to emit light toward the light emitting section 24 . The light source 23 is provided on the side surface of the edge 22 that is closer to the plate member 21 (inner side surface).

The light emitting section 24 is configured to emit the light emitted from the light source 23 in a predetermined direction. As illustrated in FIG. 3, the light emitting section 24 is provided so as to cover the light source 23. The light emitting section 24 is arranged in the left and right regions of the plate-like member 21 in the passing direction (front-back direction in FIG. 2) (in this embodiment, the region located to the left of the left end or to the right of the right end of the plate-like member 21). has been done.

The light emitting section 24 includes a first lens 241 and a second lens 242. The first lens 241 extends downward from above the light source 23 so as to cover the top of the light source 23 and one side in the left and right direction. The first lens 241 is formed of a light-transmissible resin material or the like containing, for example, a diffusing material. Examples of the diffusion material include titanium oxide, zircon oxide, aluminum oxide, silicon oxide, boron oxide, and hollow filler. Therefore, for example, the light emitted from the light source 23 is emitted to the outside of the first lens 241 while being diffused within the first lens 241 . In this way, the first lens 241 is configured to uniformly emit the light emitted from the light source 23 from the entire first lens 241.

The second lens 242 is a thin plate-like member, and is rectangular in cross-section. The second lens 242 is made of a transparent resin such as polycarbonate or acrylic material, or a transparent member such as glass. The second lens 242 is configured to emit the light emitted from the light source 23 toward the ground G located below the slope 2.

Next, with reference to FIG. 3, a description will be given of how light is emitted from the light source 23. As illustrated in FIG. 3, among the light emitted from the light source 23, the light emitted in the upward or horizontal direction enters the first lens 241, and the light emitted downward from the light source 23 (so-called , “leak light”) enters the second lens 242. Therefore, the amount of light incident on the first lens 241 is greater than the amount of light incident on the second lens 242.

The light incident on the first lens 241 is diffused by the first lens 241 and uniformly emitted upward or in the left-right direction. Since the light incident on the first lens 241 is entirely emitted from the first lens 241, the area around the first lens 241 is brighter than other parts. Therefore, by visually recognizing the first lens 241, a person near the slope 2 can recognize the presence of the slope 2 nearby and the position where the moving object 3 will pass (the left and right ends of the plate member 21). position) and can be easily recognized.

On the other hand, the light incident on the second lens 242 is emitted by the second lens 242 toward the ground G located below the slope 2. That is, the light incident on the second lens 242 passes through the second lens 242 and hits the ground G. When the light hits the ground G, it is reflected by the ground G and enters the lower surface of the plate member 21 .

Light incident on the lower surface of the information display section 212 of the plate member 21 passes through the information display section 212 and is emitted upward from the plate member 21 . Specifically, the light incident on the through hole 212a of the information display section 212 is reflected within the through hole 212a, or passes through the through hole 212a as it is and is emitted above the plate-like member 21. Note that the light emitted above the plate-like member 21 may be emitted not only above the plate-like member 21 but also in the upper right direction or the upper left direction. In this way, out of the light emitted from the light source 23, the light that passes through the second lens 242, is reflected by the ground G, and passes through the through hole 212a is emitted above the plate-like member 21, so that the information can be displayed. The portion 212 is visually recognized to be brighter than the portion of the upper surface of the plate member 21 other than the information display portion 212 . As a result, those around the slope 2 can visually recognize the shape of the information display section 212 and recognize predetermined information corresponding to the shape. The shape of the information display section 212 in this embodiment is the shape of an arrow with its tip facing forward and the shape of a wheelchair. Therefore, those around the slope 2 can easily recognize that the slope 2 is a slope for a person in a wheelchair to board the vehicle 1.

On the other hand, the light incident on the lower surface of the portion of the plate-like member 21 other than the information display section 212 is reflected by the lower surface of the plate-like member 21 and is not emitted above the plate-like member 21 .

According to the slope 2 according to the first embodiment, the light emitting section 24 emits light from the area located to the left of the left end or to the right of the right end of the plate-shaped member 21, so that when the slope 2 is near It is possible to make the person aware of the existence of the slope 2 and to indicate the position for the moving object 3 to pass through. Further, according to the slope 2, the light emitted from the light source 23 is emitted upward from the plate-like member 21, thereby obtaining predetermined information (indicating that the slope 2 is a slope for the moving object 3 riding on the vehicle 1). and information indicating that slope 2 is a wheelchair slope) can also be displayed on the information display section 212. Therefore, the slope 2 can further emphasize the presence of the slope 2, and can notify people near the slope 2 that the slope 2 is a slope for a person using a wheelchair to board the vehicle 1. .

Further, according to the slope 2 according to the first embodiment, a part of the light emitted from the light source 23 is reflected by the ground G located below the plate-shaped member 21 and is incident on the information display section 212. . Therefore, predetermined information can be displayed on the information display section 212 with a simple configuration without using an optical member for making light incident on the information display section 212.

Further, according to the slope 2 according to the first embodiment, when the plate-like member 21 includes a non-transparent member such as a metal member, the material strength of the plate-like member 21 is relatively high. Even if the vehicle is heavy, it can be passed over the slope 2.

(Modified example of first embodiment)
Next, a vehicle slope 2A (hereinafter simply referred to as "slope 2A") according to a modification of the first embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram of a slope 2A according to a modification seen from above. FIG. 5 is a sectional view taken along line BB in FIG. 4. The slope 2A differs from the slope 2 in that it includes a light source 23A disposed at a position different from that of the light source 23, and a light emitting section 24A having a configuration different from that of the light emitting section 24. Note that descriptions of parts that overlap with those of the first embodiment will be omitted as appropriate.

The configuration of the light source 23A is similar to the configuration of the light source 23, so the explanation will be omitted. As illustrated in FIG. 4, one light source 23A is arranged forward of the front end of the light emitting section 24A. The light source 23A is configured to emit light toward the rear, that is, toward the light emitting section 24A.

The light emitting section 24A extends linearly in the front-rear direction. As illustrated in FIG. 5, the light emitting section 24A includes a first lens 241, a second lens 242, and a light guide section 243. The light guide section 243 is made of a transparent member that transmits light. Examples of such transparent members include transparent resins such as polycarbonate and acrylic materials, glass, and the like. The end portion 243a of the light guide portion 243 extends linearly in the front-rear direction. A step surface (not shown) is provided on the inner surface of the end portion 243a.

Next, with reference to FIG. 5, a description will be given of how light is emitted from the light source 23A. When light is emitted from the light source 23A, the light enters the light guide section 243. A part of the light emitted from the light source 23A to the light guide section 243 is reflected inside the light guide section 243 and enters the step provided at the end section 243a. A portion of the light incident on the step provided at the end portion 243a is reflected by the step. A part of the light reflected in this step enters the inner circumferential surface of the light guide portion 243 other than the end portion 243a at an incident angle smaller than the critical angle. As a result, a part of the light is not totally reflected on the inner circumferential surface and is emitted to the outside of the light guide section 243. The light emitted to the outside of the light emitting section 24A enters the first lens 241 or the second lens 242. The optical path of the light after entering the first lens 241 or the second lens 242 is the same as that in the first embodiment, so a description thereof will be omitted.

According to the slope 2A according to the modified example, when the light guide section 243 is used, only one light source 23A is disposed in front of the front end of the light emitting section 24A, and the light source 23A is provided in the vicinity of the slope 2A. It is possible to recognize the existence of the slope 2A and to indicate the position for the mobile object 3 to pass through. Furthermore, the slope 2A emits light emitted from the light source 23A upward to the plate-like member 21 to obtain predetermined information (information indicating that the slope 2A is a slope for the moving object 3 riding on the vehicle 1). , and information indicating that the slope 2A is a wheelchair slope) can also be displayed on the information display section 212.

(Second embodiment)
Next, a vehicle slope 2B (hereinafter simply referred to as "slope 2B") according to a second embodiment will be described with reference to FIG. 6. FIG. 6 is a sectional view of the slope 2B according to the second embodiment. The slope 2B differs from the slope 2 according to the first embodiment in that it includes a light guide section 25.

The light guide part 25 is a plate-shaped, substantially rectangular parallelepiped, and is arranged below the plate-shaped member 21. The light guide section 25 may be made of the same transparent member as the light guide section 243. The light guide section 25 is configured to emit the light emitted from the light source 23 to the outside of the light guide section 25 while reflecting it inside the light guide section 25 . In a cross-sectional view, the light guide portion 25 has a substantially rectangular shape with sides in the left and right directions longer than sides in the up and down direction. The light guide section 25 includes an upper surface section 251 and a lower surface section 252 (an example of a reflective section).

The upper surface portion 251 includes a flat portion 251a and a step surface 251b. The plane portion 251a is a flat surface.

The step surface 251b is arranged in a portion of the upper surface section 251 located below the information display section 212. The step surface 251b is configured to refract a part of the light that has entered the step surface 251b and output it to the outside of the light guide section 25 (above the light guide section 25). The step surface 251b is approximately mountain-shaped. The step surface 251b is a step extending in, for example, a stippled shape or a line shape. Note that the shape, position, and size of the step surface 251b are arbitrary as long as the light can be emitted in a desired direction.

For example, aluminum is deposited on the surface of the lower surface portion 252 so as to serve as a reflective surface. In other words, the lower surface portion 252 can reflect the light emitted from the light source 22.

Next, with reference to FIG. 6, a description will be given of how light is emitted from the light source 23. As illustrated in FIG. 6, a part of the light emitted from the light source 23 enters the light guide section 25.

The light incident on the light guide section 25 is reflected inside the light guide section 25 by the flat section 251a of the upper surface section 251 and the lower surface section 252, and a part of the light enters the step surface 251b. Therefore, almost no light emitted from the light source 23 is absorbed in the light guide section 25. A part of the light incident on the step surface 251b is emitted by the step surface 251b. The light emitted by the step surface 251b is emitted above the light guide section 25.

The light emitted upward from the light guide section 25 enters the lower surface of the information display section 212 of the plate member 21 and is emitted from the upper surface of the information display section 212 .

According to the slope 2B according to the second embodiment, a part of the light emitted from the light source 23 enters the light guide section 25 and is then reflected toward the step surface 251b by the lower surface section 252 functioning as a reflection section. be done. A part of the light that has entered the step surface 251b enters the lower surface of the information display section 212 and is emitted from the upper surface of the information display section 212. When light is emitted from the top surface of the information display section 212 through the light guide section 25, which absorbs almost no light, the light utilization efficiency is as follows. It is easier to make it higher than the light utilization efficiency when the light is emitted. Therefore, the slope 2B can brightly display the predetermined information displayed on the information display section 212.

Note that the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, numerical value, form, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as they can achieve the object of the present invention, and are not limited.

In the embodiment described above, the shape of the information display section 212 is the shape of an arrow with its tip forward and the shape of a wheelchair, but it may have other shapes. The shape of the information display section 212 may be, for example, the shape of an arrow with its tip at the rear, the shape of a pedestrian, the shape of a robot, or the shape of a circle. For example, an arrow with a tip toward the rear indicates that the slope 2 is a slope for the moving body 3 to get off the vehicle 1. The pedestrian mark indicates that slope 2 is a slope for pedestrians. The round mark indicates that the moving body 3 may pass on the slope 2.

In the embodiment described above, the slope 2 does not include a light control unit that can control the amount and direction of light emitted from the light source 23, but may include such a light control unit. When the slope 2 is equipped with such a light control section, the amount and direction of light emitted from the light source 23 are controlled according to the surrounding environment of the slope 2, so that the light utilization efficiency can be increased. Can be done.

In the embodiment described above, the information display section 212 has the through hole 212a as a light-transmitting section, but even if the light-transmitting section is formed of a material having light transmittance and durability, such as an acrylic material, good.

In the above-mentioned modification, the light source 23A is arranged only at a position in front of the front end of the light emitting part 24A, but it is arranged at a position in front of the front end of the light emitting part 24A and a position behind the rear end of the light emitting part 24A. may be placed respectively.

In the second embodiment, the step 251b is provided on the upper surface portion 251 of the light guide section 25, but may be provided on the lower surface portion 252. In this case, a part of the light that has entered the step (an example of a reflecting section) is reflected upward by the light guide section 25 and emitted upward from the upper surface section 251. A part of the light emitted above the light guide section 25 is emitted from the upper surface of the information display section 212.

In the embodiments and modifications described above, the light emitting sections 24 and 24A are also arranged in a region located to the left of the left end of the plate-like member 21 or to the right of the right end of the plate-like member 21; It may be placed in For example, the light emitting sections 24 and 24A may be arranged in a region inside the left and right ends of the plate member 21 in the left and right direction, or in a region located above or below.

In the second embodiment described above, the light emitting section 24 includes the first lens 241 and the second lens 242, but the light emitting section 24 may include only the first lens 241.

In the second embodiment described above, the portion of the upper surface portion 251 where the step surface 251b is not provided, that is, the surface of the flat portion 251a, may be vapor-deposited with aluminum, for example, so as to serve as a reflective surface.
