Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a graphic panel formed by firmly connecting a plurality of substrates.

(b) Prior Art Conventionally, this type of graphic panel has been disclosed, for example, in Japanese Utility Model Publication No. 58-52806,
A crosspiece is arranged correspondingly to the connection part of the board, and the board is fixed to the crosspiece through a fixing fitting made of an elastic plate.
As the number of fixed boards increases, a large number of crosspieces are required, which takes time to install and remove, and since the boards are not directly connected to each other, they are susceptible to external forces such as vibrations during transportation, causing them to break. There were flaws.

In addition, there is a connecting means in which two metal plates are hung from the front and back at the connecting part of the board and fixed by sandwiching them, but as mentioned above, they tend to shift when external force is applied, and the metal plates are bent and deformed, preventing the intended fixing function. In addition, since the sheet metal occupies the hollow part into which the block is fitted, the system display is restricted accordingly.

Furthermore, as disclosed in Japanese Utility Model Application Publication No. 56-43216, a plurality of rectangular hollow blocks each having a notch at the corner are arranged, and the tip is hung in the hollow formed by the notch. A plurality of blocks are connected by inserting hook bolts provided with claws, but this method requires a large number of special bolts and has the disadvantage that it takes time to connect the hollow blocks.

(c) Purpose The purpose of the present invention is to eliminate such drawbacks and to provide a graphic panel that firmly connects a plurality of substrates and does not cause rattling.

(D) Structure Therefore, the feature of the present invention is that a plurality of substrates formed in a rectangular shape are abutted against each other by a partition plate that divides and forms a plurality of openings in multiple stages on the top and bottom and in multiple rows on the left and right. The tapered surfaces at both ends of the reinforcing portion formed at the abutting portion are covered with caps having tapered surfaces on the inner peripheral surface corresponding to the tapered surfaces, and the through hole of the reinforcing portion and the hole of the cap are covered. A plurality of substrates are connected by screwing the bolts into the parts in a skewer-like manner.

(E) Embodiments The present invention will be explained in detail below based on illustrated embodiments.

Figure 1 shows the graphic panel of the present invention.
As shown in FIGS. 2 and 3, the graphic panel is constructed by connecting a plurality of rectangular substrates 1 with their respective end surfaces butted together using a substrate connector 2, Decorative frame 1 on the periphery
At the same time, block 18 and block 7 are fitted on the entire surface.
It is configured by arranging an LED unit 19. The substrate 1 is formed of a partition plate 4 that defines a plurality of openings 3 in multiple stages above and below and in multiple rows on the left and right sides.
The block 18 and LED unit 19 are fitted into this opening 3.

5 is a reinforcing part provided at the intersection of the partition plate 4, and as shown in FIGS.
is provided through the hole, and tapered surfaces 7 are formed at both ends thereof. Further, a through hole 6 is formed in the reinforcing portion 5 at the peripheral edge of the substrate 1 with the end surfaces of the plurality of substrates 1 butted against each other, and tapered surfaces 7 are formed at both ends of the through hole 6, respectively. Specifically, the corner reinforcement portion 5a
is a shape in which the reinforcing portion 5 excluding the peripheral portion is divided into four equal parts in the circumferential direction, and the reinforcing portion 5b at the side portion is formed in a shape in which the reinforcing portion 5 is divided into two in the circumferential direction.

On the other hand, the connector 2 is formed of caps 8 and 9 that cover the tapered surface 7 of the reinforcing section 5, and bolts 10 that press the caps 8 and 9 onto the tapered surface 7 of the reinforcing section 5. .

Specifically, as shown in FIG. 6, the cap 8 has a tapered surface 11 on its circumference that corresponds to the tapered surface 7 of the reinforcing portion 5, and has a hole 12 into which the bolt 10 is inserted. has been done. Further, like the cap 8, the cap 9 has a tapered surface 13 on its inner peripheral surface corresponding to the tapered surface 7 of the reinforcing portion 5, and a female threaded portion 14 into which the bolt 10 is screwed.
A hole 15 is formed. Note that the tapered surfaces 11, 1 of the caps 8, 9, respectively
The minimum inner diameter dimension of No. 3 is set to be slightly smaller than the tip end diameter dimension of the reinforcing portion 5. A plurality of substrates 1 are connected using the connecting tool 2 constructed in this way to form a graphic panel. 16 is Watshiya.

Next, the connected state of the substrate 1 will be explained based on FIG. 6.

First, the substrates 1 are arranged so that their end faces are butted against each other, and the caps 8 and 9 are respectively placed on the tapered surfaces 7 of the reinforcing portions 5 of the peripheral edges of the substrates 1 formed in this state, and the holes are 12,
The bolt 10 is inserted into the bolt 15 and the through hole 6 in a skewered manner. Next, when the bolt 10 is threaded, the caps 8 and 9 are pressed toward each other, and the plurality of substrates 1 are connected by tightening the reinforcing portion 5.

According to the effect of the embodiment of the present invention, the cap 8,
Since the minimum inner diameter dimension of each of the tapered surfaces 11, 13 of 9 is set slightly smaller than the tip diameter dimension of the reinforcing part 5, the reinforcing part 5 is pushed in the radially inward direction by screwing the bolt 10. Pressure is applied and the connection state of the substrates 1 can be made stronger.

(f) Effects The present invention has effectively achieved the intended purpose with the configuration detailed above. In particular, a plurality of substrates are arranged so that their end faces abut against each other, and the tapered surfaces at both ends of the reinforcing portion formed at the abutting portion are each covered with a cap having a tapered surface corresponding to the tapered surface on the circumferential surface, and Since a plurality of boards are connected by screwing the bolts into the through-holes of the reinforcing part and the holes of the cap, the bolts are inserted into the through-holes of the reinforcing part and the holes of the cap.
Uniform force is applied from 360 degrees toward the center of the reinforcing portion, that is, the axis of the through hole, ensuring a strong connection that does not cause the substrate to shift even when external force of vibration is applied.

Furthermore, since the tapered surface of the cap fits onto the tapered surface of the reinforcing portion, distortion during assembly is automatically corrected and the normal assembled state is maintained.

Furthermore, cover both ends of the reinforced part with a cap,
All you have to do is insert the bolt and screw it in, so
The work of attaching and removing the board can be carried out extremely easily, and the shape and dimensions of the graphic panel can also be changed freely, easily and quickly.
