Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a display board for displaying advertisements and promotional posters.

(Prior Art) Conventionally, poster display boards have been constructed in such a way that a frame is integrally provided around the four sides of the main body of the display board, and a poster is pasted on the surface of the display board surrounded by the frame. things are widely used.

When attaching a poster to such a display board,
Usually, this is done by pasting or riveting the periphery of the poster along the frame edge to the periphery of the main body of the display board.

(Problem to be solved by the invention) However, according to the poster pasting structure as described above, if the poster is not pasted or tacked enough, the edges of the poster will peel off and the poster will turn over. In particular, when a display board is installed outdoors, it is subject to a large degree of curling due to the influence of rainwater, wind, etc., and this poses a problem in that the appearance of the display board is significantly impaired.

SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a poster display board that can completely solve these problems.

(Means for Solving the Problems) In order to achieve the above object, the poster display board of the present invention has the following features as shown in the drawings corresponding to the embodiments:
In a poster display board in which holding frames 2 to 5 are fixed to the four edges of a display board main body 1, the holding frames 2 to
At the front end of 5, there is a protruding edge 2a of a constant width that protrudes toward the front side of the display board main body 1 and covers the outer peripheral edge of the poster.
~5a is formed over the entire length, and the protruding edge portion 2a~
5a and the outer peripheral edge surface of the display board main body 1 are provided with grooves 6 to 9 into which fingers can be inserted.

(Function) When pasting the poster a on the display board main body 1, the outer peripheral edge of the poster a is attached to the grooves 6 to 6 of the holding frames 2 to 5.
9, and the operator inserts his or her fingers into the grooves 6 to 9 while gluing or the like.

While poster a is being displayed, if the peripheral edge of poster a peels off due to poor gluing, etc., and turns up, the turned up part b occurs within the grooves 6 to 9, so there is no external appearance. Further, the tips of the rolled portions b abut against the inner surfaces of the protruding edges 2a to 5a of the holding frames 2 to 6 to prevent further rolling.

(Embodiment) Next, an embodiment of the present invention will be explained with reference to the drawings. 1 is mainly a rectangular display board, which is made of a wooden board such as plywood, a synthetic resin board, a light alloy board such as aluminum, etc. be.

Reference numerals 2 to 5 are holding frames fixed to the four edges of the display board main body 1, which are made of the same material as the display board main body 1 or a different material. Projected edge portions 2a to 5a having a constant width and covering the peripheral edge are provided inwardly and projecting over the entire length of the display board main body 1. Grooves 6 to 9, each having a depth of about 2.2 cm and a height of about 1.8 cm, into which fingers can be inserted are provided between the surfaces of the outer peripheral edges.

Reference numerals 10 and 10 denote water holes provided on both sides of the lower holding frame 4 so as to pass through from the inner bottom surface of the shaped groove 8 to the lower surface of the holding frame 4, so that the inner bottom surface of the shaped groove 8 communicates with the outside of the frame. It is something that exists.

Poster display boards constructed in this way are fixed to the side walls of passages in underground structures, etc., and outdoors, they can be fixed to pillars erected on the side of the road, or fixed to the pillars of buildings. Used by attaching it to an exterior surface, etc.

Thus, the poster a has its upper and lower and both side edges formed between the protruding striped edges 2a and 5a of the upper and lower and both sides of the holding frames 2, 4, 3, and 5 and the outer peripheral edge surface of the display board main body 1. The poster a is inserted into the grooves 6 to 9, and a worker inserts his or her fingers into the grooves 6 to 9 while gluing or riveting the periphery of the poster a, thereby attaching it to the main body 1 of the display board.

In addition, the water holes 10 and 1 bored in the lower holding frame 4
0 is provided to drain rainwater that accumulates in the grooves 8 of the lower holding frame 4 through the display surface of the display board main body 1 to the outside of the frame when the display board is installed outdoors. However, when it is installed on the side wall of a passageway in an underground structure, it is not necessarily necessary to provide it.

(Effect of the invention) As described above, according to the poster display board of the present invention, the holding frame 2 fixed to the four edges of the main body 1 of the display board
5, protruding edges 2a to 5a of a constant width are formed over the entire length to protrude toward the front surface of the display board main body 1 and cover the outer peripheral edge of the poster a, and the ridge edges 2a to 5a and the outer peripheral edge surface of the display board main body 1 are provided with grooves 6 to 9 through which fingers can be inserted, so that when pasting the poster a on the display board main body 1, the outer peripheral edge of the poster a is held. When inserted into the grooves 6 to 9 of the frames 2 to 5, the lower edge of the frame will be inserted into the grooves 8 of the lower holding frame 4.
It is supported by the inner bottom surface of the frame and the bending of the upper edge and both side edges is prevented by the inner surfaces of the protruding edges 2a, 3a, 5a of the upper holding frame 2 and both side holding frames 3, 5, even before attachment. It is possible to maintain a stable form, and therefore, the operator can smoothly and reliably perform gluing, etc., while inserting his/her fingers into the grooves 6 to 9, without having to press the poster with his or her hands.

In addition, while poster a is being displayed, if the peripheral edge of poster a peels off due to poor gluing, etc., and turns up, the turned up part b occurs within the grooves 6 to 9, so there is no outside part. Since it is not exposed at all, a beautiful display state can always be maintained, and the tip of the rolled-up portion b comes into contact with the inner surface of the protruding edges 2a to 5a of the holding frames 2 to 6, preventing further rolling. This prevents the peeling of the poster a and ensures that poster a does not peel off.
