Description

[Detailed description of the invention] The present invention relates to the beam structure of a bulletin board, and more specifically, to the beam structure of a bulletin board including a multi-sided light box having two or more sets of bulletin boards. The present invention allows three-dimensional bulletin boards for bulletin boards and/or lighting, which are formed into various shapes depending on the installation location, to be rigidly reinforced with a single component without impairing the original display and lighting effects of the bulletin board. is to provide a useful beam structure.

An example of implementation of the present invention will be described in detail below based on the drawings.

The main body A of the bulletin board includes a frame A1 formed by connecting a required number of edge rods 1 with connectors 10, and a transparent frame A1 forming each side to which a display film or the like is attached. The frame body A1 is formed into various three-dimensional shapes such as a regular square prism, other prisms, cubes, and pyramids as shown in the drawings with the frame body A2.
A beam structure 2 is installed on the edge rods 1.1 at diagonal positions parallel to each other, and a light source 9 is attached to the beam structure 2.

The beam structure 2 is made of bendable beam strips 3 made of synthetic resin or metal.
and a beam plate 5.

Along the plate surface of the beam strip plate 3, holes 7L4 into which the screws 8 can be screwed together, and large holes 11 having a larger diameter than this and used for passing the cord 13 of the light source 9 and attaching the cord winding rod 14 are arranged at equal intervals. This beam strip plate 3 is installed diagonally across the edge rods 1 and 1 with screws 8 directly to the connectors 10 and fittings 15 (as shown by imaginary lines in FIG. 5), or the beam plate 5 (Figs. 1 to 5).

The beam plate 5 has an appropriate shape, preferably a shape similar to the cross-sectional shape of the frame body A1 (approximately rectangular in the drawing), and has a window hole 6 in the center of the plate surface through which the light source 9 can pass. The surface has holes 7 having the same diameter and the same spacing as the beam strip 3.
・A large hole 12.... Specifically, a hole 7 is provided at the corner position of each corner, and from this, a large hole 12 and an arc shape centered on the hole 7 are provided in the diagonal direction. Hole 7, large hole 12, hole 7 on the same trajectory centered on corner hole 7, and arcuate holes 7, 7
are alternately arranged at equal intervals, and arc-shaped holes 7 are provided in each month of the Japanese character shape and at the intersection position on the board surface between each corner.
The holes 7 and the large holes 12 are arranged alternately and at regular intervals.

This beam plate 5 is integrally fixed by threading screws 8 into appropriate holes 7 that match the holes 4 of each beam band plate 3.

The light source 9 uses separate short beam strips 3 to connect the upper and lower beam plates 5,
Attach with screw 8 between 5 and 5.

As a result, the beam of the bulletin board body A can be strengthened, and the light source 9 can be mounted floating in the space by the beam strip 3 and the beam plate 5.
All substrates A2 can be used as bulletin boards or lighting surfaces.

As described above, the present invention consists of a beam strip that has a beam structure with holes that can be screwed in at equal intervals along the plate surface, a window hole in the center that allows a light source to pass through, and a remaining plate surface. It consists of a beam plate with a large number of holes of the same diameter and the same spacing as the beam band plate, and the beam band plate and the beam plate are screwed into the matching holes to extend over the edge rod. Since we decided to erect the board, we cut the beam strips to a predetermined length depending on the form of the bulletin board body, and cut the matching holes of the drawing board through the beam strips or directly between the diagonally positioned edge rods. It is possible to connect and construct the structure by screwing screws into the parts.

Therefore, with a single component of the beam strip and the beam plate, any type of bulletin board body with an internal light source can be strengthened, and this beam structure can float the light source in the space to create a three-dimensional structure. The surface can be illuminated and can be used as a bulletin board or illumination surface without shadows.

Claims (1)

[Scope of utility model registration request] In a bulletin board that is equipped with a light source in a frame consisting of a border rod and has two or more sets of bulletin surfaces, a beam strip board having holes into which screws can be screwed are provided at equal intervals along the board surface; a beam plate with a window hole through which a light source can pass, and a number of holes with the same diameter and the same spacing as the beam band plate in the remaining plate surface;
