Abstract

(57) [Abstract] An object of the present invention is to detachably coat a core plate with a cover plate. A bulletin board is characterized in that a cover plate is detachably covered and fixed on at least a front surface of a core plate. A rectangular covering plate is coated on the surface of the rectangular core plate, and a plurality of parallel folding lines for bending are provided at predetermined intervals on both sides of the rectangular covering plate, and the rectangular core plate has a shape of both sides. In addition, the bent board formed by bending the folding lines on both sides of the rectangular covering plate is fixed to the back surface of the core plate.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention relates to a bulletin board intended to be used for sticking and posting election posters and other papers.

[0002]

[Prior art]

 Conventional bulletin boards have been constructed by applying the necessary printing to a board such as plywood, and fixing a wooden frame to the back surface by nailing.

[0003]

[Problems to be solved by devising]

 Since the conventional bulletin board is constructed by fixing a wooden frame to plywood, it consumes a large amount of wood and burns it after it is used. Therefore, it is a waste of wood resources. However, there is a problem that not only the volume of the storage location becomes large, but also the transportation freight and the warehouse cost may rise, and mere disposal takes a lot of labor and time. A bulletin board in which a cover plate is covered and fixed to a core plate has not been known.

[0004]

[Means for solving the problem]

 However, in this invention, the cover plate is detachably covered and fixed to the core plate, the cover plate is peeled off after use, and the core plate can be reused.

That is, the invention is a bulletin board in which a cover plate is detachably covered and fixed on at least a front surface of a core plate, and a rectangular core plate is covered with a rectangular cover plate, and both sides of the core plate are covered. The bulletin board is characterized in that both sides of the cover plate are fixed to the section. Another invention is a bulletin board characterized in that a cover plate is covered and fixed to a core plate made of plywood, laminated plate, resin board or aluminum plate, and pressure-formed paper board or water resistant paper board is used for the core board. The bulletin board is characterized in that the covering plate is covered and fixed. Still another invention is that a rectangular core plate is coated on the surface of a rectangular core plate, and a plurality of parallel folding lines for bending are provided at predetermined intervals on both sides of the rectangular core plate. The bulletin board is characterized in that bent pieces formed by bending the folding lines on both sides of the rectangular covering plate are fixed to the back surface of the core plate according to the shapes of both sides of the plate. Another consideration is that a covering piece that covers both sides of the core plate and a part of the back surface is provided on opposite sides of the covering plate having a shape and size that covers the surface of the core plate, and a plurality of fold lines are provided between the sides. It is a cover plate used for bulletin boards, which is characterized by being installed in series.

In the above description, the core plate is made of plywood, laminated wood, resin board, and aluminum plate. However, two or more single plates of the same type or different types may be laminated. If the core plate has an appropriate thickness, the nail effect is good and other objects can be nailed and fixed.

The water resistant paper board mentioned above is a sheet of ordinary paper or recycled paper laminated with a synthetic resin film (for example, a polyethylene film). Further, water resistance can be imparted by applying a resin treatment or a synthetic paste to the pressure-molded paper board. In the above, the core plate and the cover plate are fixed by sticking with an adhesive, pasting with an adhesive tape, driving with a stapler, and nailing. The folding lines on both sides of the cover plate are formed by pressing the cover plate from above to form recesses. In the used bulletin board, the bulletin board has the cover plate detachably covered on the core plate, and therefore the core plate can be reused by removing the cover plate. Also, since the coated plate is a pressure-molded paper plate or a water-resistant paper plate, it can be recycled into a cardboard material or other paper plate by chemical treatment, so there is no risk of secondary pollution from waste materials.

[0008]

[Embodiment of device]

 In this invention, a covering plate is removably covered and fixed on a rectangular core plate. The core plate can be made strong by laminating single plates. Fixing is done by adhering the cover plate to the core plate with an adhesive.

[0009]

Embodiment 1 An embodiment of the present invention will be described with reference to FIG.

The surface of a rectangular core plate 1 made of plywood is covered with a covering plate 2 made of a pressure-molded paper board similar in shape to the rectangular core plate 1, and then both sides 3 and 3 a of the covering plate 2 are covered with the rectangular core plate 1. Bending pieces 4 and 4a are formed by bending according to the shapes of both side portions 5 and 5a, and the bending pieces 4 and 4a are fixed to the back surface of the rectangular core plate 1. Both sides 5 and 5a of the rectangular core plate 1 are covered with the covering plate 2 and the bending pieces 4 and 4a, but the bending pieces 4 and 4a are fixed so that the rectangular core plate 1 and the covering plate 2 are not separated. The rectangular core plate 1 is fixed to the back surface with an adhesive tape 7 or the like.

[0011]

[Embodiment 2] An embodiment of the present invention will be described with reference to FIGS.

The surface of the rectangular core plate 1 is covered with a rectangular covering plate 2 having a shape similar to that of the rectangular core plate 1, and a plurality of bending grooves 6, 6 a, 6 b are formed on both side portions 3, 3 a of the covering plate 2. 6c are provided in parallel at predetermined intervals. In accordance with the shape of both side portions 5, 5a of the rectangular core plate 1, the bent pieces 4, 4a formed by bending the concave grooves of the both side portions 3, 3a of the covering plate 2 are formed on the shaped core plate 1. It is fixed on the back side. Since a plurality of concave grooves are provided in parallel on both sides 3 and 3a of the cover plate 2 at predetermined intervals, the sides 3 and 3a of the cover plate 2 are bent according to the shape of the rectangular core plate 1. (FIGS. 3 (a), (b), (c), and (d)). Therefore, this embodiment can cope with various shapes of the rectangular core plate with one type of the cover plate 2, so that the cost of the product can be reduced.

[0013]

[Embodiment 3] An embodiment of the present invention will be described with reference to FIGS.

This embodiment relates to a cover plate for covering the core plate 1. The cover plate 2 has a shape and size that covers the front surface of the core plate 1, and both side parts 5 and 5a of the core plate 1 and a part of the back surface are provided on opposite side parts 3, 3a of the cover plate 2. The cover covering piece 8 is continuously provided via a plurality of concave grooves 6, 6a, 6b, 6c.

[0015]

[Effect of device]

 In this invention, since the cover plate is detachably coated on the core plate, the core plate can be reused by removing the cover plate.

Further, since the cover plate is a pressure-molded paper plate or a water-resistant paper plate, it can be recycled to a paper plate such as a corrugated cardboard by chemical treatment, so that it has effects of protecting resources and preventing secondary pollution due to waste materials. Further, since the present invention is relatively lightweight and has sufficient strength, it is not only convenient to carry and handle, but also has the effect of nailing if necessary.
