Description

  The present invention relates to a housing display board that is attached to a wall surface of a building or other building, a utility pole, a streetlight, etc., and displays an address at the position, etc., and displays an address accurately without power even in a dark environment such as at night The present invention relates to a safe and durable housing display board that can be used.

  Residential display boards that are attached to the walls of buildings or other structures and display addresses, etc., are “Block display boards” attached to each block, “Town name display boards” attached to each building, Number display board "etc., but these are generally processed by pressing an aluminum plate so that the character part is raised and the paint color on the surface side of the raised character part and the ground part is changed to improve visibility There are many such things.

  In view of the purpose of the residential signboard, which is attached to the wall of a building or other building, and displays the address, etc., this residential signboard is used at night and in the dark to serve as a convenience for passers-by regardless of day or night. It is desirable that it can be easily seen even in places. However, there are cases where it is difficult to visually recognize a conventional residential display board at night or in a dark place.

  Then, this inventor devised the illumination type residence display board which attached the solar cell and storage battery which are power sources, and the illumination means connected to this to the residence display board. According to this lighting-type housing display board, in the daytime when the housing display can be visually recognized by daylight, the power is stored in the storage battery by solar power generation. , And the address, city block, town name display, etc. can be easily seen.

  However, in such a structure, many facilities such as solar cells, storage batteries, and lighting means are required to illuminate the residence display, so it is too expensive as a residence display board that needs to be installed in the town. There is a problem that it is not practical, and there is also a problem that the installation location is restricted due to the use of solar cells.

  Fluorescent paint is known as a means of obtaining a certain level of brightness without using electricity, but the fluorescent paint contains a substance with a large environmental impact such as a cyanide compound. Such substances cannot be easily adopted because they may be regulated by laws or prefectural ordinances.

On the other hand, phosphorescent materials are known as highly safe light-emitting materials that replace fluorescent paints, and phosphorescent materials with various compositions and various forms as disclosed in Patent Documents 1 to 3 below. However, weather resistance is considered to be a problem especially when used for residential display boards installed outdoors, and what structure is actually used to ensure reliable visibility? It becomes a big problem.

  The residential display board of the present invention described in each of the following embodiments uses a phosphorescent material such as “city block”, “town name”, “residential number”, etc. In addition, on the surface side of a plate-shaped body made of a translucent resin containing a phosphorescent material, “Block”, “Town name”, “House number”, etc. are printed layers. They are formed and displayed by using them, and each is attached to the wall surface of an outdoor building.

(1) 1st Embodiment (FIGS. 1-3)
As shown in FIG. 1, the residential display board 1 of the first example uses a light-transmissive plate-like body 2 as a base. The plate-like body 2 of the present example is made of a resin plate material such as a transparent acrylic plate, polycarbonate, or vinyl chloride plate. The external shape is a vertically long rectangle, and the dimensions may be determined by the installer in consideration of ease of visual recognition and the convenience of mounting on a wall portion in the town, but may be 700 mm × 140 mm, for example. As for the thickness, as will be described later, it is necessary to make light visible from the back side to the front side so that the housing display formed on the back side can be seen, and due to restrictions due to the weight when attached to the wall, it is made of acrylic As an example of the case, it is preferable to make it thinner than about 5 mm, with the lower limit being a thickness that can ensure the strength as the residential display board 1.

  As shown in FIG. 2, the back surface of the plate-like body 2 is formed with a concave portion 3 representing a residence display by a mirror character (an arrow indicates a viewing direction toward the front surface of the plate-like body 2). Although the formation method of the recessed part 3 is arbitrary, it can form by mechanical processing using machine tools, such as laser processing and an end mill, for example.

  A light irradiation layer 4 is provided inside the recess 3. The light irradiation layer 4 of this example contains a phosphorescent material as a main component. In order to manufacture the light irradiation layer 4, an appropriate amount of a phosphorescent material or a coating material containing the phosphorescent material is injected and filled into the concave portion 3 with a dispenser, and the surface is leveled so as to be continuous with the back surface of the plate-like body 2. Alternatively, an appropriate amount of coating material may be placed on the back surface of the plate-like body 2 and scraped off with a squeegee to fill the recess 3. Thereafter, when the coating material is dried and solidified, the light irradiation layer 4 is formed so as to fill the concave portion 3, and the back surface of the plate-like body 2 becomes substantially flat.

As the phosphorescent material, various phosphorescent materials such as those containing zinc sulfide as a main component or those containing a pigment using an aluminate compound as a main component can be used. For example, a phosphorescent material using the above-described aluminate compound has high luminance performance and excellent weather resistance. For example, the afterglow brightness after irradiating sunlight 20000 Lux for 5 minutes is 3 mcd / m ² or more after 12 hours. Therefore, the energy of the light stored in the phosphorescent material in the daytime is emitted as light at night, and the residential display can be brightly displayed from the front side of the plate-like body 2.

  A light-transmitting printing layer 5 is formed in a portion other than the concave portion 3 and the light irradiation layer 4 on the back surface of the plate-like body 2. Although the formation method is arbitrary, for example, a printing method using screen printing or an inkjet apparatus can be used. The color of the printed layer 5 is preferably such that it shows a high contrast with the color of the light irradiation layer 4 showing the residential display in order to enhance the visibility of the residential display under daylight. For example, if the color of the light irradiation layer 4 under daylight is white, the printing layer 5 is preferably black or blue, for example.

  As shown in FIG. 1, it is good also as providing a residence display in about 80% of the area of the upper side of the plate-shaped body 2, and providing the advertisement space 6 in about 20% of the lower side. The advertisement space 6 is an area for displaying an advertisement of a company or the like, and the installer of the housing display board 1 receives the advertising fee paid by the company as the advertiser as the price of the advertisement, and manufactures the housing display board 1. • Can be used as part of the installation cost. The advertisement provided in the advertisement space 6 is formed by printing on the back surface of the transparent plate-like body 2, but if it is desired to display it at night, the character / design of the advertisement is made of a material having a phosphorescent material. May be printed as the light irradiation layer 4. Moreover, it is good also as the light irradiation layer 4 by forming the recessed part 3 for a character, a design, etc. of an advertisement in the back surface of the plate-shaped body 2, and providing a luminous material in it.

  In the above description, the concave portion 3 is formed on the back surface of the plate-like body 2, the light irradiation layer 4 is formed in the concave portion 3, and then the printing layer 5 is formed while avoiding the concave portion 3 and the light irradiation layer 4. However, the order may be changed. For example, after forming the recess 3, the printing layer 5 may be formed avoiding the recess 3, and then the light irradiation layer 4 may be formed in the recess 3. Alternatively, the printing layer 5 may be formed on the back surface of the plate-like body 2 with a blank mirror character, the concave portion 3 may be formed on the blank portion of the blank mirror character, and the light irradiation layer 4 may be formed inside the concave portion 3.

  A light reflection layer 7 is formed on the light irradiation layer 4 and the print layer 5 on the back side of the plate-like body 2. The light reflection layer 7 reflects the light irradiated from the light irradiation layer 4 toward the back surface side of the plate-like body 2 toward the surface of the plate-like body 2, thereby reducing the light energy emitted from the phosphorescent material. It is a member for efficiently using without waste for visual recognition at night.

  Therefore, the light reflecting layer 7 is not particularly limited in material, material, manufacturing method and the like as long as it has a function of reflecting light efficiently. For example, the light irradiation layer 4 exposed on the back side of the plate-like body 2. And the white layer formed by printing a white coating material on the printing layer 5 may be sufficient, and a suitable white board may be adhere | attached on the back surface side of the plate-shaped body 2. FIG. Alternatively, it may be composed of a vapor deposition layer of aluminum or other metal, or a plate material having a light reflecting surface, a film body, etc. are separately constructed and attached to the back side of the plate-like body 2 with an adhesive or the like. May be. In addition, although the light reflection layer 7 was formed in the whole surface of the back surface side of the plate-shaped body 2, it should just be formed in the back side of the light irradiation layer 4 at least from the objective of utilizing light efficiently. However, if the light reflecting layer 7 is formed on the entire back surface side of the plate-like body 2, the light storage material of the light irradiation layer 4 and the printing layer 5 can be protected, so that the weather resistance as the residential display board 1 is enhanced. An effect is obtained.

  According to the above structure, the light irradiation layer 4 is reliably visually recognized as the character of a house display with the favorable contrast which made the color of the printing layer 5 the background in the daytime. At night, the energy stored in the phosphorescent material of the light irradiation layer 4 in the daytime is released as light, and the light irradiation layer 4 constituting the character of the housing display emits light in the recess 3 engraved in the plate-like body 2. When this is viewed from the surface side of the plate-like body 2, the residential display is lifted up in the transparent plate-like body 2 and looks somewhat three-dimensional and clearly visible.

  Moreover, since the light irradiated toward the back surface of the housing display board 1 from the phosphorescent material is reflected by the light reflection layer 7 on the back surface and is irradiated toward the surface of the housing display board 1, the light from the phosphorescent material is reflected. The utilization efficiency is high, and the visibility is higher than when the phosphorescent material is simply provided on the back side.

  Moreover, since the light irradiation layer 4 and the printing layer 5 are covered with the light reflection layer 7, the weather resistance is high, the material is deteriorated in an outdoor environment, the light storage ability is lowered, and the visibility of the residential display at night is improved. There is little risk that the print layer 5 will deteriorate or the visibility of the house display under daylight will deteriorate. Further, if the outer peripheral edge of the plate-like body 2 where the cross section of the printed layer 5 is exposed is sealed with rubber or other sealing members to prevent the entry of rainwater, dust, etc., the light irradiation layer 4 or The weather resistance of the printed layer 5 can be further increased, and an effect of reinforcing the strength of the residence display board 1 itself can be obtained.

  Moreover, since the light irradiation layer 4 is provided in the recessed part 3 formed in the back surface of the plate-shaped body 2, and is in contact with both the bottom face and side peripheral surface of the recessed part 3, it adheres to these each surface with high intensity | strength. is doing. Therefore, durability is high compared with the case where the light irradiation layer 4 is simply provided on the flat back surface of the plate-like body 2 and attached only on the back surface.

  In the manufacturing process of this example, as shown in FIG. 3A, when the concave portion 3 is smoothly finished by laser processing, the light emitted from the light irradiation layer 4 filling the concave portion 3 is Since it is difficult to diffusely reflect at the boundary with the recess 3, the residence display is clearly visible so as to represent the shape of the light irradiation layer 4 as it is. On the other hand, as shown in FIG. 3B, when the concave portion 3 is machined with a relatively coarse tool and finished to have irregularities, the light irradiation layer 4 filling the concave portion 3 is The surface of the recess 3 is firmly attached by the unevenness of the surface to increase durability, and light emitted from the light irradiation layer 4 filling the recess 3 is likely to be irregularly reflected at the boundary with the recess 3. Is displayed with a blurred outline, and a soft display effect is obtained.

  Moreover, according to this example, the light irradiation layer 4 containing an expensive phosphorescent material does not need to be applied to the entire back surface of the plate-like body 2, and has a structure filled in the recess 3 representing the residence display. Minimal amount required for display. Therefore, the manufacturing cost can be kept as low as possible.

(2) Second embodiment (FIG. 4)

On the flat rear surface of the light-transmitting plate-like body 2, a light irradiation layer 4 containing a phosphorescent material is formed in a mirror character residential display pattern. The light irradiation layer 4 is colored with a color having a good contrast with respect to white. A light reflection layer 7 is formed on the back surface of the plate-like body 2 so as to cover the light irradiation layer 4.

  According to this example, the light irradiation layer 4 is reliably visually recognized as a residence display of a predetermined color with a good contrast against the white (or mirror surface, etc.) of the light reflection layer 7 in the daytime. At night, the energy stored in the phosphorescent material of the light irradiation layer 4 during the daytime is released as light, and the light irradiation layer 4 on the back surface of the plate-like body 2 emits light, so that the residence display is clearly visible. Visibility, durability, weather resistance and other effects are the same as in the first example.

Moreover, the light irradiation layer 4 containing a phosphorescent material is provided at least in the extracted mirror character of the printing layer 5 (inside the opening of the printing layer 5 that defines the shape of the mirror character). In this example, the light irradiation layer 4 is formed on the printing material (ink) layer of the printing layer 5 as well as the portion of the extracted mirror character of the printing layer 5. A light reflection layer 7 is formed on the back side of the plate-like body 2 so as to cover the light irradiation layer 4.

  According to this example, the light irradiation layer 4 is reliably visually recognized as a white residential display with good contrast with the color of the printing layer 5 as a background during the daytime.

As shown in FIG. 13 and FIG. 14, the residential display board 1 f of this example is formed into a semi-cylindrical shape by curving the residential display board 1 of the first example along the short side direction, and inside the curved short sides up and down. A crescent-shaped holding member 10 is bonded to fix a kamaboko shape. The holding member 10 has an effect of preventing the light reflecting layer 7 and the light irradiation layer 4 from being peeled off from the curved plate-like body 2 in addition to the function of holding the plate-like body 2 in a curved shape.

  Since the housing display board 1f of the present example has a three-dimensional shape with a convexly curved front surface, it is possible to see the housing display not only from the front but also from the oblique side or the lateral direction, and has a wider viewable range. .

  In addition, although the housing display board 1f of this example forms the housing display board 1 of the 1st example and then curves and manufactures it, it curved after forming the recessed part 3 in the back surface of the plate-shaped body 2. After processing into a state, you may form the light irradiation layer 4, the printing layer 5, and the light reflection layer 7 after that. In that case, the crescent-shaped holding member 10 is not necessarily required.

(9) Eighth embodiment (FIG. 15)
As shown in FIG. 15, the residential display board 1g of this example has a plate-like body 2a made of a light-transmitting resin containing a phosphorescent material and a residential display with mirror characters on the front surface of the plate-like body 2a. The transparent transparent film 15 for protection is provided in the front surface of the printed layer.

  According to this example, the energy stored in the phosphorescent material included in the plate-like body 2a in the bright environment is emitted as light in the dark environment, and the residence display by the printed layer 5 is visible from the surface side of the plate-like body 2a. Become. That is, in the printing layer 5, light from the plate-like body 2 a behind the printing layer 5 is directly observed from the extracted mirror character (the opening portion of the printing layer 5 that defines the shape of the mirror character). From the portion of the printing material, the light from the plate-like body 2a on the back passes through the printing material of the printing layer of a predetermined color and is observed in a predetermined color. More clearly observed.
