【Example】

(Embodiment 1) A display board of the first invention will be described as Embodiment 1 with reference to the drawings. Display Board 1A of Embodiment 1
Consists of a case body 2A and a frame member 3A.

As the case body 2A, for example, a commercially available card case can be used. The case body 2A is formed by a front plate 20a and a back plate 21a facing each other, and a frame-shaped spacer 22a interposed between the front plate 20a and the back plate 21a. The front plate 20a and the back plate 21a
It is made of a hard resin (hard polyvinyl chloride or acrylic resin) and has a rectangular shape with a predetermined area and thickness. The three sides a, b, and c are joined to each other via a frame-shaped spacer 22a, and the periphery is three-dimensional. Housing part 24 surrounded by sides a, b, and c
a is formed, and the remaining side d is not joined to form an opening 23a which is opened by elastic deformation.

The space width w1 of the housing portion 24a is the same as the thickness t1 of the frame spacer 22a. Note that the case body 2A is configured such that instead of using the frame-shaped spacer 22a as a modified example for forming the accommodating portion 24a, a frame is formed inside the three sides a, b, and c of the front plate 20a or the back plate 21a. It is also possible to provide a thicker portion corresponding to the thickness t1 of the spacer 22a and join it.

The housing portion 24a is formed with an opening 23a in which the sides of the front plate 20a and the back plate 21a are not joined and open by elastic deformation.
From a, a display object 5 to be displayed (for example, a paper, a board, a film, or the like on which the display content is described) can be stored so as to be able to be taken in and out. The frame member 3A is a long member manufactured using a flexible resin (soft polyvinyl chloride) colored in advance in a desired color, and includes a tape-shaped hem portion 30a and a head portion 31a. Become.

The skirt 30a has a predetermined width w1 and a predetermined thickness t.
1 and the exposed surface 200 of the front plate 20a of the case body 2a.

The width w1 and the thickness t1 of the skirt 30a can be variously set according to the purpose. Attachment surface 302 of hem 30a
, A double-sided tape 303 was attached in advance. When the hem portion 30a of the frame member 3A is attached to the four sides a, b, c, and d, the corner portions S, S which are usually considered to be most difficult to attach.
The bonding operation in the areas 1, 2, and 3 is performed by laminating two frame members 3A that are orthogonal to each other as shown in a corner portion S shown in FIG. The cut is made by inserting a diagonal (45 °) cut 3S using the cutting tool, removing the extra length, pressing the cut 3S, ending quickly with a simple operation, and the other three corners. It can be stuck neatly like S1, S2 and S3.

Thereafter, the instant adhesive (cyanoacrylate-based) is penetrated into each cut 3S by capillary action and adheres firmly, thereby obtaining the following advantages. In other words, the frame member 3A in use, which has been attached as described above, is trying to generate a shrinking effect due to the influence of internal stress remaining during extrusion molding with tension or the influence of heat during use. Also, the shrinking action is suppressed by the strong adhesive action of the instantaneous adhesive, and the state of sticking at a predetermined position can be maintained for a long time.

Further, as shown by the dotted line 4S of the corner portion S1, the safety can be further improved by chamfering and cutting and removing approximately 1 to 2 mm to eliminate the pin angle state. In this case, the frame member 3A is a colored soft resin having a predetermined color, and since the cut surface also has the same color, it does not give a viewer a sense of incongruity (a conventional aluminum frame). When the chamfer is chamfered, the chamfered surface shows aluminum and the original metal color, and the color of the other area becomes different, giving a strange feeling to the viewer.)

The display board 1A of the first embodiment configured as described above is provided with the frame member 3 on the four sides a, b, c, and d of the exposed surface 200 of the transparent front plate 20a of the case body 2A.
