Description

TECHNICAL FIELD The present invention relates to a luminous display panel that is installed on a road surface, a floor surface, or the like, and a manufacturing method thereof.

Regarding luminous display boards that are installed on road surfaces, floors, etc. (hereinafter referred to as "road surface-mounted luminous display boards"), they differ from those that are installed on walls, ceilings, etc. However, there is a problem that it is worn by pedestrians, vehicles, etc., and it becomes difficult to recognize the contents of the guidance display.

Japanese Industrial Standards stipulate test methods and performance standards for wear resistance performance of safety signs including phosphorescent display plates. Specifically, the Japanese Industrial Standards "Safety signs - Classification of performance, performance standards and test methods" (JIS Z 9170) and the Japanese Industrial Standards cited by the same standard "General test methods for paints - Part 5: Machines for coating films physical properties-Section 10: Abrasion resistance (specimen reciprocating method)” (JIS K 5600-5-10), the test method is “Abrasive paper attached to the outer circumference of a stationary rotating wheel (Silicon carbide paper P180 grade is recommended), after rubbing the test piece of the phosphorescent material with 600 reciprocating motions, compare the wear material of the test piece with a control sample by visual inspection. Structural materials and design elements shall not show any conspicuous changes such as unevenness, peeling, splitting, cracking, tearing, chalking, distortion, large scratches, discoloration, etc." , in addition, the test equipment, test conditions, etc. are also specified in detail). Therefore, the road surface installation type luminous display panel is also required to satisfy the performance standards as a result of the above abrasion resistance performance test.

JP-A-60-17593

However, in the guidance device disclosed in Patent Document 1, no consideration is given to preventing lateral slippage, and when vehicles and pedestrians pass over it, the light-emitting block composite and the light-emitting block slip laterally.

<Overview>
The road surface installation type luminous display board of this embodiment includes a tray-shaped base plate whose surface is surrounded by a peripheral wall, and a region surrounded by the peripheral wall of the base plate (hereinafter, sometimes simply referred to as “region”). A plurality of protruding anti-slip pins, and a phosphorescent phosphor block and a non-phosphorescent phosphor block (hereinafter collectively referred to as "phosphor block") in a state of being closely fitted in the area surrounded by the pins. ). The phosphor block is provided with an insertion hole (hereinafter sometimes referred to as an "insertion hole"), and the prevention pin is inserted through the insertion hole so that the phosphor block is fitted into the above region. Furthermore, the luminous phosphor block and the non-luminous phosphor block are fitted in close contact with each other. With such a configuration, the present invention is characterized in that the phosphor blocks are less likely to shift laterally, and the shape and pattern of the guide display portion do not change, making it difficult to recognize the displayed content. In addition, by fitting the luminous phosphor block and the non-luminous phosphor block in close contact with each other, even if these phosphor blocks are worn out, the same display contents can be displayed as a kind of mixed candy (Kintaro). Another feature of the present invention is that it keeps appearing like candy (registered trademark), so that visibility is not impaired.

<Configuration>
(general)
FIG. 1 is a diagram showing an example of the configuration of the road surface installation type luminous display panel of the present embodiment. Of these, (a) is a plan view of the road surface installation type phosphorescent display panel, and (b) is a cross-sectional view taken along the line XX of (a). As shown in FIG. 1(a), the road surface installation type luminous display board 0100 of the present embodiment includes a base plate 0110, a shift prevention pin 0120, a luminous phosphor block 0130, and a non-luminous phosphor block 0140. and

(base plate)
The base plate is a plate-like member for placing and supporting the phosphor blocks with long-lasting and non-long-lasting properties, and has a tray-like shape surrounded by a peripheral wall 0111 on its surface. By providing the peripheral wall on the surface, the strength of the member is increased and the mounted phosphor block is prevented from laterally deviating from the surface.

The material of the base plate is required to be strong enough not to be deformed or damaged even if it is stepped on by vehicles or pedestrians. In addition, it is desirable that the material be easily processed. From this point of view, hard materials such as stainless steel, copper alloys, titanium alloys, ceramics, fiber-reinforced ceramics, glass-reinforced ceramics, carbon fiber composites, and carbon fiber-reinforced plastics are suitable. In addition, the shape and dimensions of the base plate should be appropriately designed in light of the guidance content and installation location. is square or rectangular with a length of about 100 to 300 mm, a width of about 100 to 300 mm, and a height of about 5 mm. The one shown in FIG. 1 is also an example of such guidance contents, and the dimensions are assumed to be 100 mm long×300 mm wide×5 mm high. In addition, the peripheral wall may be shaped so as to have an outwardly inclined surface so that a pedestrian may trip over the peripheral wall or an object may hit and damage the peripheral wall. The one shown in FIG. 1 is also an example having such a shape.

(Displacement prevention pin)
The misalignment prevention pins 0120 are a plurality of protruding pin-like members provided in the area surrounded by the peripheral wall of the base plate (only the upper left two pins are denoted by reference numerals to avoid complication, but in the example of this figure A total of 435 (=29×15) cylindrical anti-slip pins are provided.). As will be described later, the phosphor block is provided with an insertion hole, and the prevention pin is passed through the insertion hole so that the phosphor block is arranged and fixed in the area surrounded by the peripheral wall of the base plate. In other words, the anti-slip pins serve to prevent the phosphor blocks from laterally slipping on the base plate.

As for the material of the prevention pin, from the same viewpoint as the base plate, hard materials such as stainless steel, copper alloys, titanium alloys, ceramics, fiber reinforced ceramics, glass reinforced ceramics, carbon fiber composites, and carbon fiber reinforced plastics are suitable. be. The shape, size, and number of installation (or installation intervals) of the prevention pins should be appropriately designed in light of the size and shape of the base plate and the size and shape of the insertion hole of the phosphor block. For example, in the case of the shape and dimensions of the base plate and the shape and number of the anti-slip pins as shown in FIG. It is conceivable that the diameter of the prevention pin is about 2.5 mm, more preferably about 3.0 mm, and the installation interval is about 3.5 mm. It should be noted that the cross section is preferably circular because it must be assumed that the force applied to the pin is applied from all directions of 360 degrees. However, if the force from a specific direction is considered to be preferential, such as in a one-way place, design the surface area of the pin in that direction to be larger than the surface area of the pin in other directions. be able to. For example, it is conceivable to form an elliptical shape so that the direction of the surface on the major diameter side is the direction in which the force is likely to be received.

Moreover, it is desirable that the position of the apex of the misalignment prevention pin is higher than the uppermost surfaces of the phosphorescent and non-phosphorescent blocks. Such an example will be described later in another embodiment.

The anti-slipping pin may be molded integrally with the base plate, and such a structure can be obtained by, for example, pouring molten metal material into a mold for casting. Also, the misalignment prevention pin can be formed by forging. In the case of forging, if the side on which the pin is to be formed is the front side, forging may be performed using a mold in which the pin portion is concave from the front side, or may be forged in a mold in which the pin portion is convex from the back side. The former is preferable because the forging precision of the pin is higher.

In addition, since lateral displacement is relatively likely to occur in the vicinity of the periphery where the phosphorescent phosphor block and the non-phosphorescent block are in contact with each other, the displacement prevention pins may be arranged more densely in this portion.

(Luminescent phosphor block)
(Luminescent Phosphor Block: General)
The luminous phosphor block is a block-shaped member that contains a luminous material and is held in a state of being fitted in the area surrounded by the peripheral wall of the base plate, and has a hole through which the misalignment prevention pin is inserted. It has a shape for conveying information to people. Here, "shape for conveying information to people" refers to a shape for conveying information about certain guidance contents to signboard signboards, such as evacuation guidance locations and directions in the event of a disaster. In example 1, pictograms and graphics are shown for displaying guidance regarding the location and direction of emergency exits.

As a phosphorescent material, for example, a raw material of strontium aluminate (made of strontium aluminate as a mother crystal and added with silicon, phosphorus, calcium, cerium, europium, dysprosium, etc.) is used.

There is no particular limitation on the material of the matrix of the phosphorescent phosphor block, and natural resins such as rubber, plastics (meaning synthetic resins in the present invention), and composite materials using natural resins and plastics as matrix materials. In this case, a reinforcing material such as nylon fiber, glass fiber, or carbon fiber may be added to these base materials (see below for plastic base materials).

Also, the luminous phosphor block is arranged in close contact with the non-luminous phosphor block, which will be described below, at the periphery. The state in which the phosphor blocks and the non-phosphorescent phosphor blocks are fitted in the area surrounded by the peripheral wall of the base plate in such a manner that the peripheral edges of the phosphor blocks are in close contact with each other means that the phosphor blocks are arranged in the area without gaps. means the state of being "Close to each other at the periphery" means, for example, as shown in the example of FIG. It means that there is no gap between the peripheral edges of each other. Similarly, the portion where the phosphorescent phosphor block and the peripheral wall are in contact and the portion where the non-phosphorescent phosphor block and the peripheral wall are in contact are in close contact with each other, that is, the phosphor block and the peripheral wall are in a state where there is no gap. there is

In this way, (1) the phosphor blocks are arranged without gaps in the area surrounded by the peripheral wall of the base plate, and (2) the misalignment prevention pins are inserted through the insertion holes provided in the phosphor blocks. As a result, the phosphor blocks can be maintained in a completely fixed position without shifting laterally within the area surrounded by the peripheral wall of the base plate. In order to keep the periphery of the phosphorescent phosphor block and the non-phosphorescent block in close contact with each other even when the temperature changes, the thermal expansion coefficient of the phosphorescent phosphor block and the non-phosphorescent phosphor block is set to It is desirable that they are the same, and it is advantageous in this respect that the materials of the phosphorescent and non-phosphorescent blocks have the same or similar thermal expansion physical properties.

In addition, it is desirable that all side surfaces of the phosphorescent phosphor block are perpendicular to the upper surface as much as possible, so that all horizontal cross sections appear the same. By constructing in this way, even if the phosphorescent block is worn, the same shape and pattern always appear, so to speak, like mixed candy. It becomes possible to do so.

FIG. 2 is a perspective view showing an example of the shape of the phosphor block of the road surface-mounted phosphorescent display panel of this embodiment, and FIG. An example of the shape of the sexual phosphor block 0230 is shown.

Further, it is desirable that the phosphorescent block has a uniform structure, that is, the phosphorescent material is distributed as uniformly as possible within the block. Such a long-lasting phosphor block is obtained, for example, by putting a long-lasting powder into a binder such as a liquid resin, allowing it to stand still, and curing the resin in a state where the long-lasting powder is completely precipitated. It can be obtained by molding using only the precipitated portion of the powder. With this configuration, even if the phosphorescent phosphor block is worn, it can always emit light with the same brightness. Concomitantly, it becomes possible for the observer to always recognize the displayed content in the same state.

(Luminous Phosphor Block: Configuration in which the base material is plastic)
Although the material of the phosphorescent phosphor block has already been described, a plastic base material is particularly suitable for the phosphorescent block. This is because plastic has advantages such as light weight, easy processing into various shapes, and low manufacturing cost. Examples of specific plastic materials include acrylic resin, polycarbonate resin, phenol resin, epoxy resin, ABS (Acrylonitrile Butadiene Styrene) resin, and polyvinyl chloride resin. Phenolic resins and phenolic resin composites are suitable from the viewpoint of strength. From the viewpoint of transparency, acrylic resin and polycarbonate resin are suitable. Therefore, acrylic resin and polycarbonate resin are suitable as the base material of the phosphorescent block. As will be described later, the non-luminous phosphor block may be composed of a phenol resin or a phenol resin composite. In particular, in the case of a display board used on an outdoor road surface, a polycarbonate resin or the like having excellent weather resistance is suitable. Since plastic has a disadvantage of being relatively weak in strength, fiber-reinforced plastic or the like to which glass fiber, carbon fiber, or the like is added may be used as described above.

(Luminescent phosphor block: insertion hole)
As described above, the phosphorescent phosphor block is provided with holes through which the anti-slip pins are inserted, and the dimensions and positions of the holes are designed to correspond to the dimensions and positions of the anti-slip pins. From the viewpoint of preventing lateral displacement, it is desirable that the dimensions of the insertion hole be such that the anti-slipping pin can fit snugly. For example, in the case of cylindrical misalignment prevention pins and insertion holes as shown in FIGS. It is desirable that the inner diameter of the insertion hole is longer than the necessary minimum length). As an example of specific dimensions, for example, the inner diameter of the insertion hole is about 1.0 to 3.0 mm, more preferably about 2.0 mm, corresponding to the dimensions of the anti-slip pin described with reference to FIG. can be considered. Also, the position of the insertion hole is designed so that it overlaps the position of the anti-slip pin when the phosphor block is arranged in the area surrounded by the peripheral wall of the base plate.

At this time, as shown in FIG. 2, a portion 0201 of the insertion hole overlaps the peripheral edge of the phosphorescent block, and is provided in the peripheral edge of the non-phosphorous phosphor block in contact therewith. A complete through-hole may be formed by joining with a part 0202 of the through-hole provided.

Regarding the relationship between the shape of the insertion hole of the phosphorescent phosphor block and the deviation prevention pin, at least one shape may be rounded from the viewpoint of ease of fitting work. FIG. 3 is a diagram showing an example of the shape relationship between the insertion hole and the misalignment prevention pin, and shows a cross-sectional shape similar to that of FIG. 1(b). Of these, (a) is an example in which the top portion 0321 of the misalignment prevention pin 0320 is rounded, and (b) is an example in which the bottom and side corners 0331 of the phosphorescent phosphor block 0330 are rounded. indicate. When the upper surface of the phosphorescent phosphor block and the top portion of the anti-slip pin are flush with each other, if the top portion of the anti-slip pin has a rounded shape, as shown in (c) for reference. (b) is desirable because there is a risk that dust and the like may accumulate in the depression formed in the insertion hole. On the other hand, in the case of a structure in which the position of the top of the anti-slip pin, which will be described later in another embodiment, is higher than the uppermost surface of the phosphorescent block, consideration should be given to safety during walking (a). It is desirable to configure as follows. The above points also apply to the relationship between the shape of the insertion hole of the non-luminous phosphor block and the deviation prevention pin.

(Non-Luminescent Phosphor Block)
(Non-Luminescent Phosphor Block: General)
The non-luminous phosphor block is a block-shaped member that is held in a state of being fitted in the area surrounded by the peripheral wall, and has a hole through which the anti-slip pin is inserted to convey information to people. have a shape. The meaning of "shape for conveying information to people" is the same as the one described above for the phosphorescent phosphor block. It conveys information about the content.

The material of the non-luminous phosphor block is also not particularly limited, and similar to the above-described luminous phosphor block, for example, natural resins, plastics, and these with reinforced materials added thereto are used. Specifically, since there is not as strong a demand for transparency as in the case of a phosphorescent phosphor block, it is conceivable to construct the block from, for example, a phenolic resin or a phenolic resin composite, giving higher priority to strength.

Also, the non-luminous phosphor blocks are arranged so as to be in close contact with the luminous phosphor blocks at their periphery as described above. Regarding the meaning of "the state in which the phosphorescent phosphor block and the non-phosphorescent phosphor block are fitted in the area surrounded by the peripheral wall of the base plate in such a manner that the peripheral edges are in close contact with each other", please refer to the description of the phosphorescent phosphor block. It is as described inside. Further, it is desirable that the luminous phosphor block and the non-luminous phosphor block have the same coefficient of thermal expansion, and the materials of the luminous phosphor block and the non-luminous phosphor block have the same or similar thermal expansion properties. As already mentioned, it is advantageous in this respect if the

In addition, it is desirable that all side surfaces of the non-luminous phosphor block are perpendicular to the upper surface as much as possible, so that all horizontal sections appear the same. The reason is the same as described for the phosphorescent block. FIG. 2(b) shows an example of the shape of a non-luminous phosphor block 0240 in which all side surfaces are perpendicular to the top surface.

(Non-Luminescent Phosphor Block: Structure with Plastic Base Material)
The material of the non-long-lasting phosphor block has already been described, but a plastic base material is particularly suitable for the structure of the non-long-lasting phosphor block. The reason for this and specific material examples are the same as those described for the phosphorescent phosphor block.

(Non-Luminescent Phosphor Block: Insertion Hole)
The non-luminous phosphor block is also provided with a hole through which the anti-slip pin is inserted. It is the same as described for blocks.

(Other: Structure having a non-luminous block instead of a non-luminous phosphor block)
Although different from the configuration of the present invention, a configuration having a block made of a non-luminous material (hereinafter referred to as a "non-luminous block") instead of the above-described non-luminous phosphor block is also conceivable. That is, the blocks are less likely to shift laterally, and the shape and pattern of the guide display portion are not changed, making it difficult to recognize the display content. There is no difference in the effect between In addition, even if the phosphor block wears out, the phosphor will continue to display the same display content, so to speak, like a mixed candy, so that the visibility is not impaired. Even if a non-luminous block is used instead of , it is possible to express the display contents by combining with the phosphorescent block and the contrast, so that the same display contents can be maintained even if the block wears out. . However, in this case, since it is difficult to visually recognize the boundary between the non-light-emitting block and the peripheral wall at night, such a configuration is not suitable when the shape of this boundary is important for recognition of the display content.

Examples of materials for the non-light-emitting block include plastics such as acrylic resins and polycarbonate resins. In addition, the specific configuration of the non-luminous block is the same as that described above for the non-luminous phosphor block, except that it does not contain any fluorescent material. The same applies to the manufacturing method described below.

<Manufacturing method>
(general)
Next, a method for manufacturing the road surface installation type luminous display panel of the present embodiment will be described.

FIG. 4 is a flowchart showing an example of the method for manufacturing the road surface installation type luminous display panel of the present embodiment. Description will be made below with reference to the same figure.

(Base plate preparation process)
First, the processing in the base plate preparation step S0401 is performed. This step is a step of preparing a base plate having a tray-like surface surrounded by a peripheral wall and having a plurality of anti-slip pins protruding into the area surrounded by the peripheral wall. A tray-shaped base plate whose surface is surrounded by a peripheral wall can be obtained, for example, by pressing a flat plate made of metal such as stainless steel or aluminum, or by pouring a molten metal material into a mold and hardening it. The prevention pin may be attached to the base plate by welding or the like later, or may be integrally formed with the base plate during press working or casting. Both methods can be mass-produced, and the importance of road surface-mounted phosphorescent display panels in the event of a large-scale disaster has been recognized anew in recent years. This is suitable as a method for manufacturing the road surface installation type luminous display panel.

(Luminescent phosphor block fitting process)
Next, the processing in the step S0402 of fitting the phosphor block is performed. In this process, a light-storing phosphor block having a hole for inserting a misalignment prevention pin and having a shape for conveying information to a person, and having a non-light-storing phosphor block and a non-long-storing phosphor block in close contact at the peripheral edge is mounted on a prepared base plate. This is the step of fitting. Luminescent phosphor blocks may be prepared in advance.

As a method for manufacturing a luminous phosphor block, for example, a luminous powder is put into a binder such as a liquid resin, left to stand, and the resin is cured in a state where the luminous powder is completely precipitated. A molding method using only the precipitated portion of the phosphorescent powder can be used. Furthermore, the container for containing the liquid resin is made to match the shape of the completed phosphorescent phosphor block, and the phosphorescent powder is completely precipitated, and when the resin is cured, the phosphorescent powder is evenly distributed. If the amounts of the liquid resin and the luminous powder are adjusted in advance so that the amount of the liquid resin and the luminous powder is adjusted, the cured product can be taken out of the container and used as it is as the luminous phosphor block in this embodiment. Such a method is also suitable for mass production.

(Non-Luminescent Phosphor Block Fitting Process)
Next, the processing in the step S0403 of inserting the phosphorescent phosphor block is performed. This process prepares a non-luminous phosphor block that is not a long-lived phosphor and that has a shape for conveying information to a person with a hole through which the anti-slip pin is inserted, and that is in close contact with the long-lived phosphor block at the peripheral edge. It is a step of fitting into the base plate that has been formed. A non-luminous phosphor block may be prepared in advance. The process of inserting the light-storing phosphor block and this process described above may be processed in reverse order or may be processed at the same time.

As a method for manufacturing the non-luminous phosphor block, for example, casting may be performed using a liquid resin and a container having the shape of the non-luminous phosphor block in the same manner as in the above-described method for manufacturing a luminous phosphor block. Therefore, the non-luminous phosphor blocks can be mass-produced in the same way as the luminous phosphor blocks.

As described above, by using the luminous phosphor block fitting process and this process, in order to manufacture the road surface installation type luminous display board of the present embodiment, it is necessary to simply It is only necessary to fit the blocks into the base plate prepared in advance, and the positions for fitting these can be determined according to the positions of the peripheral wall of the base plate, the anti-slip pins, and the insertion holes provided in the phosphor blocks. Therefore, anyone can easily manufacture a road surface installation type luminous display panel, and furthermore, it is possible to manufacture the luminous display board at the installation site or to replace the luminous phosphor block.

<effect>
According to the invention of this embodiment, even if a frictional force (especially a frictional force in a wear resistance performance test specified by Japanese Industrial Standards) is applied due to pedestrians or vehicles passing by, the guide display part may be displaced or worn out. It is possible to provide a road surface installation type luminous display board which can keep recognizing the contents of guidance display without damaging the shape and pattern. In addition, such a road surface installation type luminous display panel can be easily manufactured.

<Overview>
The road surface installation type luminous display panel of this embodiment is characterized in that the position of the top of the anti-slip pin is higher than the uppermost surface of the luminous phosphor block.

<Configuration>
The structure of the road surface installation type luminous display board of the present embodiment is basically common to the road surface installation type luminous display board of the first embodiment. However, in the road surface installation type luminous display panel of this embodiment, in addition to the structure of the first embodiment, the position of the top of the deviation prevention pin is higher than the top surface of the luminous phosphor block. It is characterized by the fact that The configuration of the misalignment prevention pin of this embodiment will be described below. Since the rest of the configuration is the same as that explained in the first embodiment, the explanation is omitted.

(Displacement prevention pin: configuration in which the position of the top part is higher than the top surface of the phosphorescent phosphor block)
FIG. 5 is a diagram showing an example of the configuration of the misalignment prevention pin in this embodiment, and is a cross-sectional view similar to FIG. 1(b). As shown in this figure, the position of the top portion 0521 of the misalignment prevention pin 0520 of this embodiment is configured to be higher than the uppermost surface 0531 of the phosphorescent phosphor block 0530 .

With such a configuration, it is possible to prevent the wheels of a vehicle or the foot of a pedestrian from directly touching the phosphorescent phosphor block, thereby further reducing the possibility of wear of the phosphorescent phosphor block. In addition, it is possible to reduce the possibility that an object will hit the phosphorescent block and damage it.

Furthermore, by configuring in this way, the anti-slipping pin serves as a non-slip, thereby preventing a pedestrian from falling over.

How high the position of the top of the anti-slip pin is relative to the top surface of the phosphorescent block is determined so that the wheels of vehicles and the feet of pedestrians do not directly touch the phosphorescent block. be properly designed so as not to impede traffic of vehicles and pedestrians. As an example, in the case of the display board shown in FIG. 1, which is assumed to be 100 mm long and 300 mm wide, the position of the top of the anti-slip pin is about 1 to 5 mm higher than the top surface of the phosphor block. , more preferably about 3 mm high. In this embodiment, the shape, dimensions (diameter, etc.) and the number of installations (or installation intervals) of the prevention pins are considered in addition to the factors mentioned in Embodiment 1. It is designed in such a way that it does not touch the luminous phosphor block and does not interfere with the passage of these vehicles and pedestrians. The specific dimensions and the number (or the spacing) of the anti-slip pins are basically the same as those described in the first embodiment. It is desirable that the shape of the top of the anti-slip pin is rounded in consideration of safety during walking. An example of the specific shape is as shown in FIG. 3(a) described above.

<Manufacturing method>
The road surface installation type luminous display panel of this embodiment can also be manufactured by the same method as the manufacturing method described in the first embodiment. At that time, the phosphor block is preliminarily arranged so that the top portion of the anti-slip pin protrudes by a predetermined length when the phosphor block is fitted into the region of the base plate by inserting the anti-slip pin through the insertion hole of the phosphor block. By designing the height of the display plate and the length of the anti-slip pin, it is possible to achieve the effect of being able to easily manufacture and replace the display plate in the same manner as the display plate of the first embodiment.

<effect>
