Description

  The present invention relates to a guide sign such as a traffic sign and a road sign, and more particularly to a sheet-type guide sign on which a predetermined sign symbol and a sign character are marked.

  In so-called guide signs such as traffic signs and road signs, there are an external illumination type and an internal illumination type illumination method as typical illumination methods for improving visibility at night. Conventionally, a sign board has been mainly used for internally illuminated guide signs. This is hereinafter referred to as a board-type guide sign. Conventional board-type guide signs consist of a combination of a case whose front is open, a fluorescent lamp arranged in the case, and a sign board attached to the front opening of the case. For the sign board, a milky white translucent acrylic plate is used, and on the surface of the sign board, a sign pattern and characters are drawn with a semi-translucent paint.

  FIG. 6 shows the mounting structure of the sign board. In FIG. 6, the housing 1 has a stay 5 protruding in a frame shape in a part of the opening, and is fixed to a part of the inner wall of the housing 1. The sign board 31 is applied to the surface of the stay 5, the outer peripheral edge is covered with a frame-shaped decorative frame 32, the sign board 31 is sandwiched, and the decorative frame 32 and the stay 5 are fastened with bolts and nuts 33. The sign board 31 is integrally fixed to the housing 1. In addition, although the fluorescent lamp as an illumination source is built in the housing | casing 1, illustration is abbreviate | omitted in FIG.

  By the way, since an acrylic board is decolored or discolored due to aging, it must be replaced within an appropriate period of 10 years. In order to solve such problems, recently, a sign sheet in which a sign pattern or a character is drawn with a translucent paint on a fiber sheet has been used. The sign sheet has excellent weather resistance, good visibility, and is difficult to discolor and discolor. For these reasons, the work of replacing the board-type guide sign with the internally-lit type guide sign using a sign sheet has recently been advanced. Guide signs using sign sheets are called sheet-type guide signs.

However, during the replacement work, the existing board-type guide sign housing must be replaced, and the replacement work is exclusively for work in high places, including the loading and unloading of heavy objects, the lifting and lowering of the housing, installation and removal. The exchange work was very troublesome.

  The problem to be solved is that, when replacing the board-type guide sign with the sheet-type guide sign, conventionally, the entire housing of the board-type guide sign has to be replaced.

  The present invention has the greatest feature in that the housing used for the board-type guide sign is also used as the housing for the sheet-type guide sign, and the housing used for the sign board can be used as it is for the sign sheet. To do.

  According to the sheet-type guide sign according to the present invention, the sign sheet is attached to a dedicated formwork, and the formwork to which the sign sheet is attached is attached to the case. Therefore, the case is strong enough to withstand the tension of the sign sheet. It is not necessary and can be used as a sheet-type guide sign by using the casing used for the existing board-type guide sign as it is. Therefore, the board-type guide sign can be easily replaced with the sheet-type guide sign, and the material can be used together. Can be saved.

  In addition, not only when replacing the existing sign board to the sign sheet, but also when installing a new sheet-type guide sign, the housing does not need to be strong enough to withstand the tension caused by the tension of the sheet. It is possible to reduce the weight of the housing and simplify the structure. Further, since the sign sheet is attached and detached for each formwork, it is possible to easily perform attachment and removal work on site.

  The purpose of using the existing board-type guide sign as it is and diverting it to a sheet-type guide sign case is to attach the sign sheet to a special formwork and use the formwork with the sign sheet attached to the case. Realized by mounting.
