DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a bulletin board mounting structure according to the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a long rectangular board which can be used on both sides. The right and left edge frames 2 and 2 and the upper and lower edge frames 3 and 3 are attached to the four side edges of the board 1 by connecting the orthogonal positions thereof with a connection member 4.

As shown in FIG. 2, the left and right edge frames 2 and 2 are formed of an elliptical pipe material having a flat cross section, and a main body opening 5 is formed.
The holding portions 6 of the board 1 are provided on the flat side surfaces of the left and right sides, and are integrally formed. The lateral width of the left and right edge frames 2 is almost twice as large as the width of the holding portions 6.

On the other hand, the holding portion 6 'of the upper and lower edge frames 3, 3 has the same width as the width of the holding portion 6 of the main body opening 5, that is, about half the width of the left and right edge frames 2, 2. It is formed. Rail grooves 7, 7 having a slit-like opening 7a on the side surface are formed horizontally at the front and rear portions of the main body opening 5 'of the upper and lower edge frames 3, 3. Each of the edge frames 2 and 3 is formed to be long by drawing and forming an aluminum material.

The connecting member 4 has a right-angled side surface, and a holding portion 8 for holding a corner of the board 1 is formed inside the connecting member 4, and is fitted into the main body opening 5 of the left and right edge frames 2 at one outer end. The insertion portion 9 to be inserted is projected in an elliptical shape in cross section, and the insertion portion 10 to be inserted into the main body opening 5 ′ of the upper and lower edge frames 3 is projected from the other end on the outside. It is formed by integral molding.

In FIG. 3, reference numeral 11 denotes a wall-mounting metal fitting, which has a side surface T-shaped at the tip of a horizontal piece 13b formed by bending one end of a vertical piece 13a having a circular nail hole 12 into an L shape. The locking piece 14 is provided so as to protrude. The nail hole 12 is provided with nail engaging concave portions 12a, 12a communicating with the nail hole 12 at upper and lower portions of an outer peripheral edge. Then, the horizontal piece 13b of the wall hanging metal fitting 11 faces the opening 5 'at one end from the back side of the upper edge frame 3, and the locking piece 14 at the tip of the horizontal piece 13b is inserted into the rail groove 7 of the upper edge frame 3. Insert and slide to the appropriate position. Thus, the rail groove 7 of the upper edge frame 3
After mounting the wall hanging brackets 11, the right and left edge frames 2, 2 and the orthogonal portions of the upper and lower edge frames 3, 3 are connected by the connecting members 4, respectively.

When the wall-mounting fitting 11 is mounted on the rail groove 7 with the locking piece 14 facing upward, the entire wall-mounting fitting 11 is hidden behind the bulletin board as shown in FIG. Mounted in condition. Then, the nail hole 12 provided in the vertical piece 13a is hooked to the nail 16 driven into the wall 15, whereby the nail 16 is fitted into the nail hooking recess 12a, and the bulletin board is mounted in a stable state. In this case, the wall bracket 1
