Abstract

<P>PROBLEM TO BE SOLVED: To provide a bulletin board where a plurality of dovetail grooves are formed in a substantially horizontal direction in a base board. <P>SOLUTION: A pair of an upper and a lower dovetail grooves are selected in proper positions. The upper end edge of a bent photograph is fitted to the upper dovetail groove, the lower end edge is fitted to the lower dovetail groove, and the photograph does not come off the grooves by its elasticity. By using the bulletin board, the photograph is displayed only by selecting the pair of the upper and the lower dovetail grooves which are suitable for the photograph. Thus, a frame which meets the photograph in a conventional manner does not have to be prepared, and also the photograph is easily attached/detached and exchanged. Since the photograph is displayed in a bent and projected state on a front surface, perspective is enhanced, and its attraction is improved. Besides, the board is easily adaptive to a trend by decorating the base board. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

This invention relates to a bulletin board,
It is installed in schools, government offices, research institutions, hospitals, etc. to post and verify various types of Ibate scenery, post photos for evaluation, etc.
It is also used to decorate the living room of a house, children's room, toilet photos, postcards, and the beginning of writing as room decoration.

[0002]

[Prior Art] Photographs that remind us of the trajectory of our lives and the growth process of our children, inspiring the joy and joy of living. For this reason, in the past, this type of photo was usually placed in a frame and displayed on the wall or shelf in the room.

[0003]

However, in such a conventional method of using a frame, since the photograph is fitted into the frame, the frame must be selected according to the shape of the photograph, and the detachment of the photograph can be prevented. There was the inconvenience that replacement was time-consuming.

The object of the present invention is to eliminate these disadvantages.

[0005]

In order to achieve the above object, in the bulletin board according to the present invention, since a plurality of dovetail grooves are formed in the substrate in a substantially horizontal direction, a pair of upper and lower dovetail grooves at appropriate positions are formed. Select and insert the upper edge into the upper dovetail groove while bending the photograph, and insert the lower end edge into the lower dovetail groove to prevent the dovetail from coming off due to the elasticity of this photograph. Can be planned.

Incidentally, joint means is provided at the edge of the substrate,
If the plurality of substrates can be attached and detached in a planar manner, the plurality of substrates can be freely connected to each other in an appropriate shape to manufacture a display my display having a shape desired by a user.

Further, if the substrate is provided with a sandwiching claw, sheets having no elasticity can be posted by sandwiching the sheets between the sandwiching claws.

Further, if the holding tool is removably installed in the dovetail groove of the substrate, the sheets having no elasticity can be posted by holding the sheets in the holding tool.

1-3, B is a display board, 10
Is the substrate. The substrate 10 is formed in a substantially square shape by injection molding of synthetic resin, for example, lightweight plastic. 11,11, ... are inverted trapezoidal in cross section, so-called dovetail,
It is formed on the surface of the substrate 10 substantially parallel to the horizontal direction. As shown in FIGS. 1 and 2, the dovetail grooves 11, 11, ...
Used when posting elastic sheets S such as photographs.
When installing the elastic sheets S such as photographs in the dovetails 11 and 11, first, the elastic sheets S such as photographs are curved in a convex shape on the front side, and the upper edge portion thereof is resisted against its elasticity. Upper dovetail
The lower end edge may be inserted into the dovetail groove 11 above.

A step portion 12 is formed on the upper edge of the substrate 10. Further, 13 and 13 are locking holes, which are formed at both ends of the stepped portion 12. This locking hole 13,13
Is for passing a locking pin or the like (not shown) when the substrate 10 is installed on the wall surface (in the room).

[0012] Reference numerals 14, 14, ... Are holding claws, which are formed on the stepped portion 12 of the substrate 10 so as to project. The holding claws 14, 14, ... Have elastic force, and as shown in FIGS.
The upper edge of the can be pinched. In particular, it is useful when posting non-elastic sheets S such as drawing paper and copy paper.

FIGS. 4 and 5 show the holding tool 20. Reference numeral 21 denotes a base portion of the holding tool 20, which has a triangular prism shape (a bottom surface isosceles triangle). Further, 22 is a sandwiching part,
It is swingably installed on the upper edge of the base 21 via a shaft 22 (see the arrow in the figure). The sandwiching portion 22 is formed by bending a plastic piece, a metal piece, or the like, and by the elasticity based on the material,
The sheets S can be elastically sandwiched by placing them at the tip thereof. In this clamp 20, the base 21 is connected to the dovetail groove 11 of the substrate 10.
The substrate 10 is inserted by sliding it onto the substrate 10.
Is installed in. Here, the base 21 is a dovetail groove of the substrate 10.
Since it has a shape that fits 11, it can be fitted with almost no gap, so the stability of the installation state is good.

As shown in FIG. 6, joint convex portions 31, 31, ... Are provided at the edge of the substrate 10 and joint concave portions 32, 32 ,. As shown in the drawing, by fitting and inserting the joint convex portion 31 and the joint concave portion 32 of the adjacent substrates 10 and 10, the two can be connected. This connection can be freely expanded two-dimensionally, and FIG. 8 shows an example thereof. In this way, the layout can be devised according to the purpose of use, and the usefulness of the bulletin board can be increased.

[0015]

Since the bulletin board according to the present invention has a plurality of dovetail grooves formed in the substrate in a substantially horizontal direction, a pair of upper and lower dovetail grooves at appropriate positions are selected, and the upper edge of the photograph is bent in a curved state. Is inserted into the upper dovetail groove and the lower end edge thereof is inserted into the lower dovetail groove, so that the elasticity of this photograph can prevent the dovetail groove from coming off.

Therefore, if this display board is used,
Since it is possible to post a photo by simply selecting a pair of upper and lower dovetails that are suitable for the photo, it is not necessary to prepare a frame suitable for the photo as in the past, and the photo can be easily removed and replaced. Is.

Furthermore, by using this bulletin board,
Since the photograph can be displayed in a curved convex shape on the front surface, the perspective can be enhanced and the attractiveness thereof can be improved.

Furthermore, it is easy to adapt to the fashion by decorating the substrate.

A joint means is provided on the edge of the substrate,
If the plurality of substrates can be attached / detached in a planar manner, the plurality of substrates can be appropriately connected to each other to manufacture a display my display having a shape desired by a user.

Further, when the holding claw is provided on the substrate, a wide variety of sheets having no elasticity can be posted by sandwiching the sheets between the holding claws.

Further, even if the sandwiching tool is removably installed in the dovetail groove of the substrate, by sandwiching the sheets in the sandwiching tool, it is possible to post even non-elastic sheets.
