Description

  The present invention relates to a method for repairing various signs such as road signs. More specifically, the present invention relates to a method for repairing a sign in which a notation part such as characters, symbols or figures described on the surface of the sign and a base part other than the notation part are represented in different colors.

  Conventionally, as a sign for a driver of an expressway, for example, in consideration of day and night visibility, a character or graphic notation portion is white and a base portion is green or blue, or a notation portion is green or blue and a base portion A white interior lighting type sign is often used. The signs as described above are inevitably deteriorated due to aging, and the green or blue portion is gradually faded and whitened, and there is a problem that visibility during daytime running is lowered.

  As a conventionally known technique for such a problem, there is a method of coating the surface of a sign with a sheet material having an antifouling function, as shown in Patent Document 1 below. However, there is a problem that when the uncoated label is deteriorated or is deteriorated even if the coating is made, it can be dealt with only by replacing the deteriorated label itself.

Japanese Patent Laid-Open No. 11-81158

  The present invention has been proposed in view of the above problems, and even when a sign such as a road sign is deteriorated due to secular change or the like, it is easy to replace the display panel on the sign surface or replace the entire sign. An object of the present invention is to provide a repair method for a sign that can be reproduced at low cost.

  In order to achieve the above object, the marker repairing method according to the present invention has the following configuration. That is, a method for repairing a sign in which a notation part such as a character, symbol, or figure described on the surface of a sign such as a road sign and a base part other than the notation part are displayed in different colors, respectively, Alternatively, the repair film having a translucent color similar to the color of at least one of the base portions is attached to the surface so as to cover the notation portion and the base portion, and then the repair film. A portion corresponding to the notation portion or the base portion is cut out and removed.

  As described above, the repair method of the sign according to the present invention includes a repair film having a translucent color similar to the color of at least one of the sign notation part or the base part, and the notation part and the base part. After covering and sticking, the marker can be repaired easily and quickly by an extremely simple operation of cutting out and removing the portion corresponding to the notation portion or the base portion of the repair film. In particular, the present invention does not require replacement of the entire sign, so material costs and construction costs are low, and industrial waste is not generated, so that disposal costs are also unnecessary. Further, since the work is easy and can be performed in a short time, for example, in the case of a road sign or the like, the time for restricting the passage of the automobile for the work can be reduced. Furthermore, by sticking a repair film on the surface of the sign, cracks and scratches are repaired to improve durability, and the sign surface becomes smooth and does not diffusely reflect, thereby improving both day and night visibility. Furthermore, it has an anti-scattering effect, and it is possible to avoid the debris of the sign from falling even if it is damaged.

  In particular, green or blue commonly used in road signs and the like is severely whitened (fading) due to age-related deterioration due to ultraviolet rays. However, in the deterioration signs that display white letters with green or blue on the ground, When a light-transmitting film sheet made of polyvinyl chloride is attached, the same visibility can be recovered without having to replace the label itself with a new one. In the case of a polyvinyl chloride film sheet, the weather resistance is guaranteed for a predetermined period at the time of factory production, and it is possible to re-paste it in the future.

  Hereinafter, a case where the present invention is applied to a road sign used for an expressway or the like will be described in detail based on an embodiment shown in the drawings. FIG. 1A is a perspective view before repairing a road sign to which the present invention is applied, FIG. 1B is a perspective view showing a repaired state, and FIG. 1C is a perspective view after repairing.

  The road sign A of this embodiment is a so-called internal illumination type road sign, in particular, an acrylic fiber as a front display panel 10 in which an illuminator (not shown) such as a fluorescent lamp is built in a substantially box-shaped main body case 1. This is applied to a non-reflective internally illuminated road sign using a board.

  The display panel 10 has a green or blue substrate 11 with a white notation 12, and in the case of the figure, the notation 12 includes characters “Exit” and “EXIT” and a figure indicating an arrow. Are listed.

  In FIG. 1 (a), the green or blue substrate portion 11 is faded (fading) and gradually becomes white due to aging deterioration due to ultraviolet rays or the like due to long-term use, and the distinguishability from the notation portion 12 is lowered and is difficult to visually recognize. It is in the state.

  In such a state, at least one of the base part or the notation part is repaired, and particularly when any one of the base part or the notation part is faded as described above, at least It is desirable to repair the fading one.

  Therefore, in the present embodiment, the repair film 13 having the same color and translucency as the green or blue base portion 11 before fading is displayed on the display including the base portion and the notation portion as shown in FIG. After sticking on the surface of the panel 10 so as to cover almost the entire surface of the panel 10, the part corresponding to the notation 12 of the repair film 13 is cut out and removed as shown in FIG. is there.

  Although the thickness and material of the repair film 13 are appropriate, for example, when applied to a non-reflective internal lighting type road sign as shown in the figure, a polyvinyl chloride resin having a thickness of about 0.08 mm to 0.10 mm. A light-transmitting film is suitable.

  When the repair film 13 as described above is attached to the surface of the display panel 10, it is desirable that the surface of the panel 10 be attached after the surface is cleaned by an appropriate means. In addition, in the case where a part of the attached repair film 13, for example, a portion corresponding to the notation portion 12 is cut out and removed, a notch groove is formed with a cutter or the like at the boundary portion between the base portion 11 and the notation portion 12. What is necessary is just to peel and remove the repair film 13 of the part corresponding to the description part 12. FIG.

  By cutting out and removing the portion corresponding to the notation portion 12 as described above, the original white notation portion 12 appears there, and the original base portion 11 is covered with a new green or blue repair film 13. A display with high contrast and good visibility is reproduced.

  It should be noted that the surface of the repair film 13 to be bonded to the display panel 10 is not provided with an adhesive or the like in advance, and is attached to the panel surface by electrostatic force or pressure sensitivity, and a portion corresponding to the notation 12 is cut out. After the removal, the repair film 13 is attached to the display panel 10 with an adhesive. Alternatively, a pressure-sensitive adhesive is provided in advance on the surface of the repair film 13 to be attached to the display panel 10 and is initially pressed lightly on the panel surface to cut out and remove the portion corresponding to the notation portion 12, and then the repair film 13 is displayed on the display panel 10. It is made to adhere firmly by pressing firmly on the surface. Alternatively, the repair film 13 may be attached to the panel surface with a normal adhesive and the portion corresponding to the notation portion 12 may be cut out and removed before the adhesive dries.

  Further, in the above embodiment, the base portion is repaired. However, when the notation portion 12 is easily faded, for example, when the white base is marked with green or blue, the notation portion is repaired. In addition, both the notation part and the base part may be repaired. In particular, when the marking portion or the base portion is white and difficult to see due to dirt or the like, it is preferable to repair the white portion.

  Furthermore, although the above embodiment is applied to a non-reflective type internally lit road sign, it may be a non-reflective type internally lit road sign or a reflective type of road sign. It can also be applied to various other signs.

  In the non-reflective internal illumination type road sign as shown in FIG. 1, after the surface of the display panel 10 in which the green or blue substrate 11 is faded due to aging due to ultraviolet rays or the like after long-term use is cleaned with a cleaner or the like. A repair film 13 made of a light transmitting film made of green or blue polyvinyl chloride resin having a thickness of 0.08 mm was attached to almost the entire surface of the display panel 10 by pressure or the like. Next, after removing the portion corresponding to the notation portion 12 consisting of the letters “Exit” and “EXIT” in FIG. 1 and the figure indicating the arrow with a cutter or the like, the repair film 13 is peeled off and the same position is again removed. Reattached with adhesive.

  As a result, the original white notation portion 12 appears in the portion where the portion corresponding to the notation portion 12 is cut out and removed, and the original base portion 11 is covered with a new green or blue repair film 13 and has a contrast. In addition to the daytime visibility, the difference between the notation and the substrate became clear and the visibility could be greatly improved.

In addition, in the above repair, there is one caretaker per sign and four workers, and the surface area of the display panel that can be repaired per day can be about 12 m ² , and the cost of the repair is It was found that about 1/3 to 1/4 when the display panel 10 was replaced and about 1/10 when the entire sign was changed.

  As described above, the sign repair method according to the present invention can be easily and inexpensively repaired and recycled without replacing the display panel or replacing the entire sign, and by attaching a film to the panel surface. For example, even if the sign is damaged due to an accident or the like, there is an effect of preventing the sign from being scattered, and it is possible to repair the panel with cracks or scratches by attaching a repair film as it is.
