Abstract

PROBLEM TO BE SOLVED: To obtain the bulletin board which is advantateous in storage and transportation by enabling the bulletin board to be contracted by folding and also vertical expanded. SOLUTION: The bulletin board 1 is constituted by connecting mutually adjacent upper and lower parts of two rectangular panels 2 and 2 by a hinge while the panels 2 are arranged side by side, and freely folded into two. Both the edges of the panels 2 and 2 are fixed to columns 4 and 4, and lock mechanisms 11 which fix small-diameter pipes 4b are provided by screwing to the external surfaces of the lower ends of large-diameter pipes 4a, so that the vertical lengths of the columns 4 can be adjusted continuously. Pedestals 5 are fitted to the lower ends of the columns 4 and 4 so that pipe joints 6 can be rotated on the axes of the columns 4 and 4; and leg pipes 7 are run through the joints 6 horizontally movably along the axes, and rubber legs 8 are provided below both the ends of the leg pipes 7. Thus, the two panels can freely be folded and the columns can freely be extended, so that the whole body can be folded flatly to low height.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulletin board suitable for being installed in an election site and posting a candidate's name at various elections.

[0002]

2. Description of the Related Art For example, in national and local elections, it is necessary to post a candidate's name on a polling place, and a bulletin board is used for this posting.

A conventional bulletin board has a structure in which columns are provided on both sides of a single panel having a size necessary for posting, and the panel is self-supporting so that the panel is vertical.

[0004]

By the way, since the conventional bulletin board has a structure in which the columns are fixed to the panel of one piece, the shape cannot be changed, and the bulletin board is bulky because it requires space for storage and transportation. There is a problem that it is inconvenient.

Therefore, an object of the present invention is to provide a bulletin board that can be reduced by folding and is advantageous in space for storage and transportation.

[0006]

In order to solve the above problems, the invention of claim 1 connects two panels by a hinge so that they can be folded in two, and the side edges of the two panels which are opposite to each other are connected to each other. The structure is such that the fixed support columns can be expanded and contracted vertically and a pedestal for holding the upright state of the support columns is provided at the lower ends of both support columns.

According to a second aspect of the present invention, the pedestal is formed by using a leg pipe, and is attached to a pipe joint rotatably provided at a lower end portion of the column so as to be movable in a direction orthogonal to the column. It is configured to be.

According to the third aspect of the present invention, in the pedestal, one end of each leg pipe is pivotally attached to both ends of the post at the lower end of the post along the plane direction of the notice plate, and the links are pivotally fixed to the tips of both leg pipes. It is configured such that the end portion of is removably fixed to the column.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

In the first example shown in FIGS. 1 and 2, the bulletin board 1 has two rectangular panels 2 and 2 arranged side by side, which are joined together by a hinge 3 at the upper and lower sides thereof to form the same surface. It can be folded in half from the unfolded state, and the columns 4 and 4 are fixed to opposite side edges of both panels 2 and 2, and the standing state of the bulletin board 1 is held at the lower ends of both columns 4 and 4. It has a structure in which pedestals 5 and 5 are provided.

The panels 2 and 2 are made of plywood or synthetic resin.
The struts 4 and 4 on both sides, which are formed by using an aluminum plate or the like, are vertically expandable and contractable by a large-diameter pipe 4a of a higher rank and a small-diameter pipe 4b of a lower rank fitted in the large-diameter pipe 4a. 4a is fixed to the outer edges of the panels 2 and 2. The columns 4 and 4 are made of aluminum or synthetic resin.

A lock mechanism 1 for fixing the small diameter pipe 4b to the outer surface of the lower end portion of the large diameter pipe 4a by screwing or the like.
1 is provided so that the vertical length of the column 4 can be adjusted steplessly.

The pedestal 5 has a pipe joint 6 attached to the lower ends of the columns 4 and 4 so as to be rotatable around the axes of the columns 4 and 4, and a leg pipe 7 is movable in the axial direction to the joint 6. The leg pipe 7 is provided with rubber feet 8 at the lower ends of both ends.

The bulletin board 1 of the first example is constructed as described above, and when used, as shown in FIG. 1, both panels 2 and 2 are deployed on both sides and the columns 4 and 4 are extended. Lock the leg pipe 7 of the pedestal 5 and the pipe joint 6 at the center.
If it is slid so that the leg pipes 7 are at right angles to the plane directions of the panels 2 and 2, the bulletin board 1 is stable and self-supporting, and the candidate names are posted on the surfaces of the panels 2 and 2. do it.

When the bulletin board 1 is not used, FIG.
As shown in Fig. 2, both panels 2 and 2 are folded in two at hinges 3 and 3, the lock mechanism 11 is released to contract both struts 4 and 4, and one of the leg pipes 7 and 7 of the pedestal 5 is released. By pulling it to the position where it is positioned directly below the panels 2 and 2, the whole becomes compact and convenient for storage and transportation.

Next, in the second example shown in FIGS. 3 and 4, the peripheral edges of the panels 2 and 2 are surrounded by a frame material 9, and the columns 4 and
4 is made of an aluminum material or a synthetic resin material so that it can expand and contract.

The pillars 4 and 4 have a cross section in which an upper pillar 4c fixed to the outer edges of the panels 2 and 2 and a lower pillar 4d in which the upper pillar 4c is housed are fitted so as to be vertically slidable. The lock mechanism 1 is formed on the upper end of the lower support column 4d.
1 is provided.

The third example shown in FIG. 5 and FIG. 6 is the support columns 4 and 4.
A square pipe is used as the upper pipe, the upper small-diameter pipe 4e and the lower large-diameter pipe 4f are fitted so as to be vertically expandable and contractable, and the lock mechanism 11 is provided at the upper end of the large-diameter pipe 4f.

The pedestal 5 has leg pipes 12, 12 at one end on both side surfaces located in the plane direction of the panels 2 and 2 so as to sandwich the large diameter pipe 4f at the lower end of the large diameter pipe 4f. Links 14 and 14 pivotally attached so that they can be pivoted up and down with
The other end of the large diameter pipe 4f is detachably connected with a bolt 15 in the middle thereof.

Both leg pipes 12 and 12 are projected in mutually opposite directions, and the other ends of the links 14 and 14 are connected to the large diameter pipe 4f.
, The two-legged pipes 12 and 12 are fixed horizontally in the front-rear direction and are grounded, and the standing state of the bulletin board 1 is maintained.

Further, as shown in FIG. 6, if the links 14, 14 are uncoupled from the large diameter pipe 4f, the leg pipes 12,
12 and the links 14, 14 can be arranged along the axial direction of the outer surface of the large diameter pipe 4f, and the pedestal 5 can be folded in a low bulk.

The bulletin board 1 can be used for purposes other than election, and the columns 4 and 4 and the pedestal 5 shown in each example can be used in any combination.

[0023]

As described above, according to the present invention, the two panels can be folded and the struts can be extended and retracted, so that when not in use, the whole can be folded flat and low, Storage and transportation become space-friendly.

Further, folding and unfolding can be easily performed.
