Abstract

PROBLEM TO BE SOLVED: To effectively use a mat as various information media such as an outdoor propaganda-advertisement or guide means by arranging light emitting parts or light reflecting parts visible from the outside of the mat on the mat. SOLUTION: A mat M is formed as a grating-shaped square frame body as a whole out of a large number of main bars 2M juxtaposed at equal intervals in the lengthwise direction of a flat groove P and plural cross bars 2C to separate these main bars 2M from each other. Plural light emitting diodes LE as light emitting parts mutually juxtaposed at intervals in the lengthwise direction are provided. In this way, since the light emitting parts LE or light reflecting parts visible from the outside of the mat M are arranged on the mat M, in a comparatively and easily attractive mat M existing in a position lower than a line of sight of a passerby, the light emitting parts LE themselves emit the light. Therefore, the mat can be effectively used as an information media such as a propaganda-advertisement or a guide to a passerby.

As shown in FIGS. 1 and 2, a flat groove P as a recess is provided in the vicinity of an entrance / exit of a building (not shown), for example, in front of the entrance, on an aisle F that is outdoor and hardened with concrete or asphalt. In this flat groove P, a mat M for wiping off mud, dirt and the like adhering to the shoe soles of a passerby who is about to enter the building is housed and held so that its longitudinal direction is orthogonal to the pass direction. Has been done. That is, at the opening edge portion of the flat groove P, a metal edge frame member 1 which surrounds the edge portion over the entire circumference is integrally provided along with the horizontal frame portion 1 a of the edge frame member 1. , Vertical frame part 1b standing upright from this
By this, a mat receiving step portion 1s which is recessed from the passage surface F by the thickness of the mat M is formed, and the peripheral edge portion of the mat M is placed and supported on the upper surface (on the horizontal frame 1a) of this step portion 1s. It is like this. By adopting such a support structure for the mat M, the upper surface of the mat M is formed substantially flush with the passage surface F and forms a part of the passage surface F.

In the illustrated example, the mat M extends along the longitudinal direction of the flat groove P, and has a large number of main bars 2M arranged in parallel at equal intervals in a direction orthogonal to the extending direction, and between the main bars 2M. A plurality of crossbars 2C extending in the parallel direction and separated from each other so as to be integrally connected are formed into a rectangular frame body having a grating shape as a whole. In the illustrated example, each main bar 2M is formed to have a substantially T-shaped cross section, that is, horizontal rib-shaped overhanging portions 2f are provided on the upper end portions of both side surfaces of the bar 2M. The strength is increased and the surface area of the upper end surface is wide. Each bar 2M, 2C is molded from a metal material such as stainless steel or a high-strength synthetic resin such as FRP.

A large number of parallel slit-shaped openings 3 extending in the longitudinal direction of the flat groove P are formed between the main bar 2M and the cross bar 2C which are adjacent to each other.
A portion of the opening 3 (in the example shown in FIG. 1, several rows in the center in the two rows on the right side of the mat) has a rectangular parallelepiped, indivisible synthetic resin elongated in the longitudinal direction of the opening 3.
The blocks B ₁ are fitted and fixed. Further, in another part (in the illustrated example, several lines in the center in the two rows on the left side of the mat in FIG. 1), a plurality of rectangular parallelepiped composites are arranged in a row along the longitudinal direction of the openings 3. A dividable second block B ₂ made of resin small blocks b, b ′, b ″, b ₀ is fixed.

B ₂ (b, b ′, b ″, b ₀ ) have engaging recesses 4 formed on both side edges of the upper portion and extending along the side edges. The engaging recesses 4 project from the upper end of the main bar 2M. By engaging with the portion 2f, the blocks B ₁ and B in the opening 3 are
₂ upward movement is restricted, also the respective blocks B _1, B ₂ within the opening 3, the motion along the opening longitudinal direction, is regulated directly by the crossbar 2C. Each block B ₁ , B
For assembling _{2 to} the mat M, for example, the blocks B ₁ and B ₂ are fitted into the openings 3 of the mat M from below with the back plate 5 not attached, and then the blocks B ₁ and B ₂ are fitted. The back plate 5 engaging with the lower surface is fixed to the lower surface of the mat M by welding or the like.

As shown in FIGS. 3 and 4, in each of the first blocks B ₁ , a plurality of light emitting diodes LE as light emitting portions arranged in the longitudinal direction of the first block B ₁ are spaced apart from each other, and between the light emitting diodes LE. There is provided an internal wire 6 ₁ for feeding the wire and a first socket half body 7 connected to the internal wire 6 ₁ , and the first socket half body 7 is detachably connected to this. The waterproof socket S is configured in cooperation with the second socket half body 8 on the waterproof cable Ca side. Such a waterproof socket S is a state in which the first and second socket halves 7 and 8 are connected to each other, while preventing water from entering from the outside and connecting terminals (not shown) in the respective socket halves 7 and 8. Since they are brought into contact with each other and their structures are well known in the art, description thereof will be omitted.

A space 10 ₁ extending along the longitudinal direction is formed in each first block B ₁ , and the light emitting surface of each light emitting diode LE (that is, a hemispherical head portion) is formed in this space 10 _1. The surface) faces upward. By providing such a space 10 ₁ , there is an advantage that the heat generated when the light emitting diode LE emits light can be efficiently diffused to the entire block B ₁ . Further, a reflection surface 11 for diffusely reflecting light is provided on the bottom surface of the space portion 10 ₁ as needed, and in order to form this reflection surface 11, for example, the space portion 1
A means such as sticking a reflection plate or a reflection tape on the bottom surface of 0 ₁ , coating a reflective paint, or directly attaching minute unevenness that diffusely reflects light to the bottom surface is adopted. According to the special provision of the reflecting surface 11 as described above, it is possible to prevent the light from escaping to the lower side and efficiently concentrate the light amount to the upper side.

[0016] To form the space portion 10 ₁ of the first block B _1, the block B ₁ in the illustrated example, a box-shaped block body Bm ₁ having a space portion 10 _1, the block body Bm ₁ It has a two-part structure composed of a strip-shaped upper surface portion Bt ₁ integrally attached to the open upper surface. In this case, by making the upper surface portion Bt ₁ narrower than the block body Bm ₁ , both of them Bt ₁ , Bm ₁ can be used to easily form the engagement recess 4 in the first block B ₁ . Incidentally, the block structure for forming the space portion 10 ₁ is not limited to the two-part structure of the illustrated example, that is, a plurality of block elements are separately molded so as to sandwich the space portion 10 _1, and after molding them The mating surfaces of the block elements may be bonded together.

At least a portion of each first block B ₁ located right above the light emitting diode LE is formed of a transparent or translucent synthetic resin so that the light emitted from the light emitting diode LE is It is easily visible from above block B ₁ . In the illustrated example, the entire upper surface portion Bt ₁ of the block B ₁ is made of a transparent or translucent synthetic resin, but a portion of the upper surface portion Bt ₁ located directly above the light emitting diode LE. Alternatively, only the transparent or translucent synthetic resin may be formed.

Etc. are not provided, but simply wear between the small blocks.
Only detachable connecting means are provided.

In particular, the first small block b has a box-shaped block body bm and a plate-shaped upper surface attached to the open upper surface thereof in the same manner as the first block B ₁ in order to form the space 10 ₂ therein. Although it is a two-part structure including the part bt, the block structure for forming the space 10 ₂ is not limited to the two-part structure as in the case of the first block B ₁ . Incidentally, in this embodiment, the light emitting diode LE is not provided in the second small block b ′ having the first socket half body 7, but in the second small block b ′, the inside with the terminals 12 and 13 is provided. in addition to the wire 6 ₂ and the first socket half 7, may be provided in the same structure as that shown the light emitting diode LE in the first small block b.

FIG. 6 is a single view of the first small block b, and FIG. 7 (a) is a simplified plan view showing how the small blocks b, b ′, b ″ and b ₀ are connected to each other. However, the connection structures between the small blocks b, b ′, b ″ and b ₀ adjacent to each other are basically all the same. As is clear from these drawings, small blocks b adjacent to each other,

Is formed. The internal wiring 6 is provided in the fourth small block b _{0.
Although not provided with 2} , there is provided a detachable fitting connection means having the same structure as the male / female terminals 12 and 13.

Therefore, a plurality of small blocks b, b ', b ", b for displaying desired characters or figures on the mat M are displayed.
By appropriately combining _0's and arranging them in tandem, and adjoining the male and female terminals 12, 13 of the adjacent small blocks b, b ', b ", b ₀ , respectively, in a detachable manner, it is possible to obtain a total of 1 Two second blocks B ₂ can be constructed,
Moreover, the internal wiring 6 _{2 of} each small block b, b ′, b ″
It is possible to feed and wire each other in sequence. Thus, the internal wirings 6 _{2 of the} small blocks b, b ′, b ″ and the groups of male and female terminals 12 and 13 that connect them to each other cooperate with each other to form the block B ₂ (that is, the small blocks b, b ', b ") form a feed wiring portion 16 which passes vertically. In particular, the male and female terminals 12 and 13 are small blocks b adjacent to each other.
Since it serves both as a mechanical coupling means between b ′ and b ″ and an electrical connection means, it can contribute to the simplification of the structure.

In the illustrated example, the small blocks b, b ', b "
Although the male terminal 12 is provided on one end surface and the female terminal 13 is provided on the other end surface, as shown in FIG. 7B, only a female terminal 13 or only a male terminal 12 is provided on both end surfaces. A block (which may be any of b, b ′, b ″, b ₀ ) may be used. The fourth small block b ₀ may be omitted, and in this case, A gap is formed in the opening 3 between the end of the second block B ₂ and the crossbar 2C, but the block B ₂ is provided on both sides of the main bar 2
By adhering to the M and the lower back plate 5, the movement of the block B ₂ along the opening 3 can be reliably regulated.

It is desirable to select a material having excellent durability, impact resistance, weather resistance, water resistance and the like as the synthetic resin material forming each block B ₁ and B ₂ .
It is possible to extend the life of the blocks B ₁ and B ₂ itself and the light emitting diode LE, and it is also effective in preventing the occurrence of electrical accidents such as disconnection and short circuit. Incidentally, as in a second embodiment (FIGS. 9 to 11) described later, a protective plate G such as tempered glass having a transparent or translucent property is provided on the upper surface of each block B ₁ , B _2.
If they are attached together, the impact resistance will increase.

A hollow pillar 18 is erected on the ground or in a proper place on the building away from the flat groove P.
An electric power supply device ES for supplying electric power to each of the light emitting diodes LE is arranged on the upper side of 8. As shown in the block diagram of FIG. 8, a solar battery So, a storage battery 20 for storing electricity generated by the solar battery So, and energization from the storage battery 20 to each light emitting diode LE are provided in the housing 19 of the power supply device ES. An energization control unit 21 for controlling the temperature and an illuminance detection sensor Se capable of detecting that the surroundings are dark are housed. The light receiving unit r of the solar cell So and the sensor Se are provided on the upper wall surface of the housing 19. Is facing.
The energization control unit 21 has an original energization control function (automatic turn-on / off function) in which the energization is performed based on a detection signal of the illuminance sensor Se while the surroundings are dark or for a predetermined night period set in advance. , A function of preventing overcharge to the storage battery 20 and a function of preventing backflow, and further, a light emitting diode L according to an arbitrary input operation to a manual switch means (not shown).
It also has a function of automatically flashing E or controlling energization so that it can emit light even in the daytime.

The electric wires 22 extending from the energization control section 21 of the electric power supply device ES are provided in the support column 18 and the conduit tube 2 buried in the ground.
3 to extend into the flat groove P from an appropriate position on the inner surface of the flat groove P, and to be detachably connected to one end of the second waterproof cable Ca ₂ in the concave groove Pi via a waterproof socket S. To be done. Thus, it is desirable that the pillar 18 is installed outside the flat groove P at a proper place where it does not obstruct the passage. By installing the power supply device ES on the pillar 18, the pillar M The electric power supply device ES does not need to be specially incorporated in the device, so that the structure of the mat device can be simplified. Moreover, by placing the power supply device ES on the pillar 18, it is possible to increase the degree of freedom in the installation position of the power supply device ES, and for example, the solar cell So without depending on the position of the flat groove P (and therefore the mat M). It is possible to dispose the power supply device ES at an optimum location for collecting light.

As is apparent from FIG. 1, in order to add a function of advertising to the mat M, the arrangement position of the light emitting diodes LE in the mat M is carefully devised. That is, by appropriately selecting the array position, it is possible to display a character such as a company name or a message (in the example shown, a hiragana character "Welcome" is drawn) or a figure (picture) on the mat M. is there. Moreover, in the display, if a split type block structure in which a plurality of small blocks b, b ′, b ″ are arranged in a row in series, such as the second block B ₂ , is often used,
The degree of freedom in arranging the diodes LE in the mat M can be increased by variously selecting the arrangement position of the diode-embedded small blocks (first small block b) in the small blocks b, b ′, b ″ group. In that case, it is not necessary to specially prepare various kinds of first blocks B ₁ having different light emitting diode LE arrangement positions, so that the cost can be reduced accordingly.

9 to 11 show a second embodiment of the present invention.
In this embodiment, the split type second block B is used._Two

The protective plate G has the upper surface portion Bt.₁Similar to the strip shape
And the constituent material of the plate G is not damaged or deformed.
Hardened glass that does not easily occur and is transparent or translucent
Materials with high hardness and strength such as stainless steel are selected.

On the surface of the protective plate G, various symbols to be attached to the mat M, characters such as company names and messages, or the light transmitting window portion Ga having a form corresponding to a figure (picture) are used as a light shielding portion. The coating film Co is formed by a coating film forming means such as masking coating. In the light emitting state of the light emitting diode LE ', light is prevented from propagating upward at the portion corresponding to the coating film Co of the protective plate G, and the light leaking from the light transmitting window portion Ga makes the outline of the transmitting window portion Ga clear. Will appear,
The light transmitting window portion Ga constitutes the light emitting portion of the present invention. According to such a configuration, since the character, symbol or figure to be displayed on the mat M can be expressed finely and smoothly as the contour of the light transmitting window portion Ga, the character or the like has a complicated form. However, this can be expressed reasonably and accurately, and the number of light emitting diodes LE 'used (two in the illustrated example) can be reduced.

[0030] In the particular illustrated embodiment, since the light-emitting surfaces of the pair of light-emitting diode LE 'are arranged laterally to opposite sides of the space portion 10 _1, the space portion 10 ₁ between the mutually
Can increase the amount of light that illuminates the inner and reflective surface 11, yet the special of the reflecting surface 11 and the space portion 10 _1, by sufficiently diffuse the light emitted from the light emitting diode LE 'upper,
That is, since it can be directed to the light transmitting window portion Ga side,
The light from the light emitting diode LE ′ can be efficiently concentrated without being biased to the light transmitting window portion Ga side. As a result, even when the light transmission window portion Ga is formed over a relatively wide area in one block B ₁ , and even when the number of the light emitting diodes LE ′ installed is relatively small as in the illustrated example, the light is not emitted. From the transmission window portion Ga, it is possible to emit a sufficient amount of light upwardly of the block B ₁ and substantially uniformly in each portion.

Thus, the space 10 ₁ and the reflecting surface 11 cooperate with each other to form a light emitting diode LE 'as a light emitting body.
The diffuser section Di of the present invention is configured to diffuse the light emitted from the block B ₁ toward the light transmitting window section Ga.
If the space 10 ₁ can be wide vertically and the high-luminance light emitting diode LE 'can be used, the reflecting surface 11 may be omitted or the light emitting diode LE may be provided.
The light emitting diode L does not have to have the light emitting surface of E'sideways.
Since the light from E ′ can be sufficiently diffused and directed toward the light transmission window portion Ga side evenly, the reflection surface 11
Can be omitted as necessary, and the light emitting surface of the light emitting diode LE 'can be directed upward or obliquely upward as required. In addition, temporarily, the space section 1
0 ₁ does not exist, the light transmitting window portion Ga and the light emitting diode L
Even when there is a light-transmitting portion such as glass or synthetic resin having excellent light-transmitting property between the light-emitting diode L and the light emitting diode E '.
Since the light from E ′ can be sufficiently diffused and directed to the light transmission window portion Ga side evenly, in this case, the light transmission portion and the reflection surface 11 constitute the diffusion portion Di. .

In this embodiment, the coating film Co as a light shielding portion is formed on the surface of the protective plate G provided on the open upper surface of the block B _1.
Although the light transmission window portion Ga as the light emitting portion is formed, the Co and Ga may be formed not on the front surface of the protective plate G but on the back surface thereof. Also in the case of a structure having a top surface portion Bt ₁ as in the first block B ₁ of the first embodiment of the block B ₁ (see FIG. 3) is, as a light-shielding portion on the front or back surface of its upper portion Bt ₁ A coating film Co or a light transmitting window portion Ga as a light emitting portion may be formed. In this case, a transparent or transparent protective plate such as tempered glass is attached to the surface of the upper surface portion Bt _1. Or it does not need to be pasted.

In this embodiment, therefore, a set of points formed by a large number of light emitting diodes LE, such as symbols to be attached to the mat M, characters such as company names and messages, or figures (pictures), is provided (see FIG. 1).
Is not displayed, and since the outline of the light transmitting window portion Ga as the light emitting portion can be expressed finely and smoothly by applying the light shielding coating Co to a desired portion, the character to be displayed Even if the shapes and shapes are complicated,
These can be expressed reasonably and accurately, and the number of light emitting diodes LE to be used can be reduced.

FIGS. 12 and 13 show a third embodiment of the present invention, which differs from the previous embodiment in that the power supply device ES 'is provided directly on the mat M. . That is, the middle portion of the plurality of main bars 2M is cut out on one side of the group of blocks B ₁ arranged in parallel at the central portion of the mat M, and the lower surface of the mat M around the cutout portion is below the cutout portion. A receiving frame 25 covering the side is fixed, and a rectangular parallelepiped housing 19 'of the power supply device ES' is integrally fitted on the receiving frame 25. In the housing 19 ', a solar cell So, a storage battery 20, an illuminance sensor Se and an energization controller 21 are provided as in the first embodiment, and the open upper surface of the housing 19' faces them. A transparent or translucent protective plate 28 covering the light receiving part r of the solar cell So and the illuminance detection sensor Se is attached, and the protective plate 28 is the same as or similar to the protective plate G of the second embodiment. A material having high hardness and high strength such as tempered glass of the above material is selected.

On the bottom surface of the flat groove P, a lateral groove Pi 'which directly communicates with one side of the concave groove Pi is formed so that the lower surface of the receiving frame 25 is exposed in the groove, and the lateral groove Pi' is also formed. An extension of the first waterproof cable Ca ₁ arranged in the groove Pi extends out in Pi '. Further, a waterproof socket S connected to the energization control unit 21 of the power supply device ES ′ is provided on the side of the receiving frame 25, and the energization control unit 21 connects the energization control unit 21 to the first waterproof cable C via the waterproof socket S.
It is connected to the extension of a ₁ . The handling of the waterproof cables Ca ₁ and Ca ₂ in the mat M is basically the same as in the above embodiment. It should be noted that the power supply device ES 'provided on one mat M may be one or plural as in the illustrated example. In the latter case, there is an advantage that even when the number of light emitting diodes LE installed is large, it is possible to cope with it without difficulty.

When the power supply device ES 'is directly provided on the mat M as in this embodiment, special wiring is provided outside the flat groove P for supplying power to the mat M, and a support pillar for power supply device equipment is provided. It is not necessary to erect the 18 specially, and the construction becomes simpler and the existing flat groove P can be easily coped with only by replacing the mat M.

Thus, in each of the above embodiments, the electric power generated by the solar battery 19 of the power supply device ES, ES 'is stored in the storage battery 20 during the daytime, and the device ES, ES' is energized when it becomes dark. Control unit 21 waterproof cable Ca
Power can be supplied to each light emitting diode LE of the mat M via (Ca ₁ , Ca ₂ ) to cause them to emit light. According to the light emission of each of the light emitting diodes LE, it is convenient that a passerby can be easily and accurately informed of the position of the mat M in front of the entrance of the building.

Further, since the mat M is located below the line of sight of a passerby and is relatively easy to be noticed, in such a mat M, each light emitting diode L can be used at night or day and night.
If E is made to emit light, the mat M can be greatly utilized as an information medium (medium) such as a publicity advertisement or guidance for passersby. In this case, by appropriately selecting the arrangement position of the light emitting diodes LE in each of the blocks B ₁ and B ₂ on the mat M as illustrated in FIG.
Alternatively, as illustrated in FIG. 9, a light-shielding coating film Co (that is, a light-shielding portion) is appropriately formed on the upper surface of the block B _1, and a light-transmitting window portion Ga (that is, a light-emitting portion) having a desired shape is provided on a portion other than the coating film Co. By forming the, it is possible to display various characters or figures (pictures) such as company names and messages.

In recent years, it is often practiced to light up buildings and trees to enjoy the scenery. However, the mat M on the passageway F at the entrance is equipped with the light emitting diode LE as a light emitting portion and light transmission. By providing the windows Ga and making them emit light in accordance with the surrounding landscape, a beautiful landscape with a sense of unity can be obtained. In this case, by appropriately selecting the arrangement positions of the light emitting diodes LE and the light transmitting window portions Ga, it is possible to express a design-like pattern or design that matches the surrounding landscape.

Furthermore, FIGS. 14 and 15 show a fourth embodiment of the present invention. In this embodiment, instead of providing the light emitting portion such as the light emitting diode LE on the mat M in each of the above embodiments, a light reflector RE as a light reflecting portion having a reflecting surface facing upward is provided. The light reflector RE is embedded in the blocks B ₁ and B ₂ made of synthetic resin, similarly to the light emitting diode LE in each of the above embodiments. The structure of the blocks B ₁ and B ₂ themselves and the structure for mounting them on the mat M are basically the same as those in the above-mentioned respective embodiments, but there is a clear difference from the above-mentioned respective embodiments in the internal wiring and the internal wiring. No electricity supply means (for example, a waterproof socket, a waterproof cable, a power supply device, etc.) is required, and the structure is simplified and the cost is reduced. The light reflector RE is placed in the first block B ₁ or the second block B ₂ (that is, the first small block b).
For embedding in the inside, for example, these blocks B ₁ and b are divided into upper and lower parts, and a reflection plate or a reflection tape as a reflector RE is attached to a surface of the lower block element facing the upper block element, or Both the block elements may be adhered to each other after applying a reflective paint or directly forming a minute uneven portion that diffusely reflects light. When the blocks B ₁ and b are integrally molded, a reflector or a reflection tape as the reflector RE is set in the molding die in advance at the time of molding, and the blocks B ₁ and b are integrally embedded in the blocks B ₁ and b. You can do this.

When the light reflector RE is formed into a horizontal flat plate shape as shown in FIG. 15 (a), the light reflector RE most reflects light from directly above, and as shown in FIG. 15 (b). When it is formed in a simple mountain shape or in an arch shape as shown in (c), diffused reflection to the surrounding space becomes possible. At least a portion of each of the blocks B ₁ and B ₂ located directly above the light reflector RE (in the illustrated example, the entire block B ₁ and B ₂ ) is formed of a transparent or translucent synthetic resin. Light reflector R
The form of E is not limited to the example shown in the figure, and various forms are possible. Further, by scattering glass beads on the surface of the light reflector RE, the direction of reflected light can be directed in more directions.

Thus, in this embodiment, the light reflector RE provided on the mat M reflects the light of another light source (for example, the illumination of a building where the mat M is placed in front of the entrance or the building in the vicinity thereof, a street lamp, etc.). By doing so, the position of the mat M can be easily and accurately notified. Moreover, like the light from the light emitting diode LE in each of the above-described embodiments, the light reflected by the light reflector RE is used as an information medium (medium) such as a publicity advertisement or a guide for passersby, or a landscape illuminated by the surroundings. It can be used as a harmonized optical decoration means.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments and various embodiments can be made within the scope of the present invention. For example, in the illustrated example, the solar battery is used as the power supply of the power supply device, but a dry battery or an external AC power supply may be used instead of the solar battery. Further, in the illustrated example, the light emitting diode is shown as the light emitting portion or the light emitting body, but other light emitting means such as a discharge lamp or a light bulb can be used. Further, one mat M may incorporate both the integrated first block B ₁ and the divided second block B ₂ , or one of the first or second blocks B ₁ and B _2. Only may be incorporated.

As described above, according to the invention of each claim,
Since the mat is provided with a light-emitting part or a light-reflecting part that is visible from the outside of the mat, the light-emitting part itself emits light in a mat which is lower than the eyes of a passerby and relatively easy to see, or The light reflector is another light source (for example, the mat M).
By reflecting the light of a building placed in front of the entrance or the building near it, streetlights, etc., it is used as an information medium (medium) for advertising, guidance, etc. to passersby, or lighting up the surroundings. It can be effectively used as an optical decoration means in harmony with the landscape, and such a mode of use does not hinder traffic.

According to a second aspect of the invention, the light emitting portion or the light reflecting portion is a light emitting body or a light reflecting body embedded in a synthetic resin block, and at least the light emitting body or the light reflecting body of the block is provided. Since the part directly above the body is transparent or translucent, even if the upper surface of the mat is stepped on, the light emitter or light reflector can be effectively protected by the synthetic resin block. it can.

Further, according to the invention of claim 3, in a block made of synthetic resin having a light-shielding portion and a light-transmitting window portion on the upper surface thereof, a light-emitting body which emits light to be irradiated to the outside through the light-transmitting window portion is arranged. Since the light transmission window portion is provided as the light emitting portion, the display target can be expressed finely and smoothly as the contour of the light transmission window portion, and therefore the display target is a complicated form such as characters and figures. However, it is possible to express them reasonably and accurately, and further, it is possible to reduce the number of light emitting elements used and contribute to cost reduction.

Further, according to the invention of claim 4, the light emitted from the light-emitting body is diffused in the block made of the synthetic resin having the light-shielding portion and the light-transmitting window portion on the upper surface to diffuse the light. Since the diffusing portion that directs the light to the light-emitting portion is provided, the light emitted from the light-emitting body can be effectively directed to the light-transmissive window portion side without bias, and therefore the light-transmissive window portion in a single block has a relatively wide area. Even if it is formed over the entire length, or the number of light emitting elements used is relatively small, it is possible to emit a sufficient amount of light toward the outside of the block from the light transmitting window portion, and to substantially uniformly emit each portion.

Further, according to the invention of claim 5, an electric power supply device capable of supplying electric power to the luminous body is provided outside the mat, and an electric wire connected to the electric power supply device is passed through the ground into the mat accommodating recess of the passage surface. Since it is pulled out and connected to the light emitting body, it is not necessary to provide the power supply device on the mat or in the vicinity thereof, which can contribute to the simplification of the structure of the mat device. Moreover, it is possible to increase the degree of freedom of the installation position of the power supply device, for example, when using a solar cell,
It is possible to arrange the power supply device at an optimum location for light collection without depending on the mat position.

Further, according to the invention of claim 6, a mat is provided with a power supply device having a solar cell, a storage battery for storing electricity generated by the solar cell, and an energization control unit for controlling energization from the storage battery to the light emitter. Since it is provided on the mat, it is not necessary to perform special wiring outside the mat to supply electric power to the mat, the construction of the mat device is simplified accordingly, and the mat can be easily replaced with the existing mat device. Also, frequent battery replacement is not required.

Further, according to the invention of claim 7, a part of a plurality of slit-shaped openings arranged in parallel in the mat is fitted with a plurality of small blocks made of synthetic resin arranged in a row along the longitudinal direction of the openings. These small blocks are provided with feed wiring portions that vertically pass through the small blocks, and at least some of the small blocks are embedded with the light emitters connected to the feed wiring portions. By selecting various arrangement positions of the light-emitter-embedded blocks in the mat, the degree of freedom of arrangement of the light-emitters in the mat can be increased at low cost. In addition, the sending wiring portion simplifies wiring between the light emitters in the column block group.
