  2. Description of the Related Art Conventionally, movable display signs that are not fixed on land have been used as display devices for advertising merchandise at stores or notifications such as road construction. An easy-to-assemble signboard as shown in Fig. This signboard is provided with a pair of left and right vertical poles and a pair of upper and lower horizontal tubes as a frame, and an advertisement display sheet is spanned between the poles and the horizontal tubes. The signboard shown in Patent Document 1 can display various advertisements and postings by exchanging advertisement display sheets.

Utility Model Hei 6-28879

However, the signboard according to Patent Document 1 has the following problems.
(1) When changing the display contents, it is necessary to create a new advertisement display sheet, but it is necessary to form a bag-like part that can be inserted through the horizontal tube on the top and bottom of this sheet. The process increases.
(2) In order to replace the advertisement display sheet, it is necessary to break the connection between the vertical pole and the horizontal tube, which requires much labor for the replacement.

  The present inventor pays attention to the fact that the above problem can be solved by using a display board as a display means and posting the advertisement display sheet on the display board so that the advertisement display sheet can be replaced. Repeated research.

In doing so, the following matters were considered.
In other words, a general standing signboard is manufactured and stored in advance in a factory or a work place, transported to a site where it is necessary, and assembled and used there. For this purpose, it is required to have a structure that can be easily stored and transported. In order to meet the demand, it is necessary to reduce the number of parts and to be lightweight.
Moreover, being able to manufacture with a small amount of material not only contributes to the effective use of limited resources, but also contributes to a reduction in manufacturing costs.

Therefore, the present inventor uses a thin plastic sheet or film as the material of the display board, forms a groove on the display board surface by vacuum forming or pressure forming this, and between the fitting body fitted into the groove. (A) The advertisement display sheet can be replaced easily, and (a) it is not only lighter but also bulky when the display boards are stacked. Because it can be stored and transported easily, and (c) the number of parts can be reduced, not only can it contribute to the effective use of resources but also it can contribute to the reduction of manufacturing costs.
Further, it has been found that if the insertion body for mounting or fixing the advertisement display sheet is also used as a support for supporting the display board, a member for mounting or fixing the advertisement display sheet becomes unnecessary, which further reduces the number of parts.

  Therefore, as a test, a display board having a groove formed on the plate surface with a plastic sheet was manufactured, and when the advertisement display sheet was sandwiched between the insertion body and the insertion body, the insertion body was not removed from the groove. Or fixing was not enough. When the cause was investigated, it turned out that the opening part of a groove | channel expands by the elastic deformation and bending of a display board, and an advertisement display sheet removes from a display board when an insertion body removes from a groove | channel. The inventor has further conducted research and development, and has completed a display device that solves the above problems.
