Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulletin board, and more particularly to a bulletin board formed by mounting a required number of fixed plate members for a poster to a frame.

[0002]

2. Description of the Related Art Conventionally, a bulletin board for a poster of a candidate set in accordance with the provisions of the Public Office Election Law at the time of election is formed by striking a large plywood board on which posts, notice numbers, and the like are written on a pillar such as a square bar. In this case, each candidate posted a poster by pasting his or her own poster in a predetermined section with glue or the like.

[0003]

Such a conventional bulletin board needs to be prepared in a size corresponding to the number of candidates each time an election is made, and when a poster is pasted on a plywood with glue or the like, it is difficult to peel it off. It was customary to discard after the election because it is difficult to reuse or reuse. Also, if the number of candidates is prepared before the number of candidates is determined, an unnecessarily large bulletin board is formed, which causes problems such as wasting resources, securing installation space, and generating a large amount of garbage. Furthermore, since a large plywood plate is used, the assembling and disassembling operations are complicated.

[0004] In order to solve such a problem, there has been proposed a bulletin board made of synthetic resin or aluminum from which a poster can be easily removed (Japanese Patent Laid-Open No. 9-101755). This bulletin board
It is constructed by connecting a required number of plates in the lateral direction between the columns, and is easy to assemble and disassemble, and can be reused.
However, when a large number of boards are connected, the middle part of the connection is structurally fragile and easily broken by the wind or the like, so that strength comparable to that of the conventional bulletin board cannot be expected. In addition, since the spacing between the columns changes according to the number of connected boards, it is necessary to change the installation position of the columns each time an election is made.

Further, a bulletin board (Japanese Patent Laid-Open No. 9-288644) in which a plate member for one poster is slid and inserted in a frame having rails in the order of posting, or a large plate member is fitted into the recess of the horizontal rail member at the upper and lower ends. A configured bulletin board (Japanese Patent Laid-Open No. 8-16107) has also been proposed. In such a bulletin board, the upper and lower sides of the plate member are fixed, but the left and right sides are not fixed, and there is a possibility of sliding, which is structurally vulnerable. In the former case, it is necessary to insert the plate member without any gap in order to prevent sliding, and the number of posters that can be posted on one bulletin board is limited. In the latter case, a large plate member is used, so handling is difficult. It is complicated.

Accordingly, an object of the present invention is to provide a reusable bulletin board which is structurally strong, can be constructed in a size corresponding to the number of posters to be displayed, is easy to assemble and disassemble, and requires no storage space. And

[0007]

According to a first aspect of the present invention, there is provided a bulletin board wherein at least a surface of the bulletin board is made of a resinous material, and a pair of opposed longitudinal edges and lateral edges are opposed to each other. A groove is formed on the end face of one edge, and a plate member having a rib formed on the end face of the other edge, a frame supported by a support, and a corner of each plate member are formed. A coupling member having a concave portion to be fitted, and a fastening member for fixing the coupling member to a frame, and the adjacent plate members are fitted with the grooves and the ribs, and the end faces of the edges are formed. It is characterized in that the corners of the plate members are connected to each other by the fastening members via the coupling members and the frame members.

According to a second aspect of the present invention, in the bulletin board, the frame includes a plurality of horizontal rail members extending vertically in the vertical direction at intervals approximately corresponding to the length of the plate member in the vertical direction. Features.

According to a third aspect of the present invention, in the bulletin board, the corner of the plate member is chamfered, and the concave portion of the connecting member has a front plate,
Connect the back plate, the front plate and the back plate at their center,
A connection portion having a smaller diameter than the front plate and the back plate, and the fastening member is formed integrally with the coupling member such that a tip screw portion protrudes from the back plate of the coupling member, A chamfered corner of the plate member is fitted into a concave portion of the coupling member.

[0010]

In the bulletin board according to the first aspect of the present invention, adjacent plate members are interconnected by grooves and ribs formed on the end surfaces of the edges, and the corners are mutually connected by a connecting member. The required number of plate members are attached to the frame by fixing the joined corners to the frame with fastening members.

[0011] Adjacent plate members can be fitted at the upper and lower edges and at the right and left edges by fitting the groove and the rib, or when the groove is formed along the edge, by sliding the rib into the groove. While being connected, it is mutually connected also in a corner by a connecting member.

The plate members interconnected at the corners are fixed to the frame by fastening members via the connecting members. That is, in a single plate state where a plurality of plate members are connected,
It is attached to the frame at the corners of the plate member, and has the same structure as a conventional bulletin board in which a large-sized plywood plate is punched into the frame at a narrow interval (an interval corresponding to the size of the plate member) using a number of nails. Become. On this occasion,
The fastening members may be arranged on the frame in advance, and the plate members may be connected to adjacent plate members while fixing the plate members one by one to the frame, or the plate members may be connected to each other at the edges and the corners. After being combined to form a single plate, it may be fixed to the frame by a fastening member.

Since at least the surface of the plate member is made of a resinous material, the poster can be easily attached with a double-sided tape or the like, and the poster attached with adhesive or the like can be easily peeled off. It can be reused. Furthermore, if you make the board member the size of one poster,
Transporting, assembling, and disassembling operations can be performed by one person, and the storage space when not in use can be reduced.

That is, the bulletin board according to the first aspect has an effect of being easy to assemble and disassemble, reusable, and easy to store, while having a strength comparable to a conventional bulletin board.

The frame of the bulletin board according to the second aspect is constructed by assembling a horizontal rail member and the like and is disassembled. That is, since the frame is formed by attaching the crosspiece member or the like to a support such as a column, the assembly and disassembly work of the bulletin board can be performed quickly and easily. In addition, since it is compacted when dismantled, the storage space can be reduced.

The required number of plate members is attached to the frame. The number of plate members is adjusted by adjusting the number of horizontal rail members to adjust the number of steps of the frame or by adjusting the length of the horizontal rail members. The size of the bulletin board or the shape of the bulletin board according to the installation environment can be formed.

According to a third aspect of the present invention, the concave portion of the connecting member in the bulletin board includes a front plate, a back plate, and a small-diameter connecting portion, and a fastening member is integrally formed on the back plate of the connecting member. Therefore, the connection between the plate members at the corners and the attachment of the plate members to the frame can be performed by one member.
