Description

[Detailed description of the invention] This invention is useful for devices and equipment, such as displaying whether valves installed at key points in pipelines installed in factories, etc. are open or closed. The present invention relates to a display device that selectively displays at least two types of states that can be assumed.

The simplest conventional indicator of this kind is a single board with the words ``open'' and ``closed'' on both sides, if used for a valve. There are display devices that are hung near the valve, but in such displays, the plate piece rotates around the center line when it is hung, and the orientation of the plate surface can easily change. When the direction changes,
The disadvantage is that the display also changes.

In order to improve these drawbacks, a system was devised in which two of the above display boards were used, and the boards with the same display were placed on top of each other so that the board faces faced each other and then hung. has been done.

In such a display, even if the two overlapping display boards rotate about the center line when hanging,
Although the display does not change and the same display is always displayed, each display board may be subjected to non-human external forces against the wishes of the person displaying the display, such as being blown by the wind, causing one display board to reverse and cause the other display board to turn over. may polymerize to the opposite side of the display board, changing the display.

The present invention aims to provide a display device that can overcome these drawbacks.

Embodiments of the present invention will be described below based on the drawings. 1 shows different markings on both sides of a circular plate;
For example, a display board with the word "open" displayed on one side and the word "closed" on the other, 2 is a board with the same shape as display board 1 with the above display on both sides. 3 and 4 are transparent holes drilled in the periphery of these display boards 1 and 2 at corresponding positions directly above each display; It is a connecting ring that loosely fits into the holes 3 and 4, and is made by winding a thin wire into a coil. Reference numeral 6 denotes a hanging fitting, and below the circular hanging part 7, there is an opening part 8 which is opened to the extent that each of the above-mentioned display boards 1 and 2 can pass through in a direction perpendicular to or nearly perpendicular to the width of the board. It is made by bending and molding thick wire so as to be continuous, and the connecting ring is loosely fitted into the opening 8 of the hanging fitting 6.

Next, we will explain how the display with the above configuration is used, taking as an example the case of displaying the open/closed status of valves installed at important points in pipelines installed in factories, etc. If you want to display the open state of the valve by hanging the hanging part 7 of the hanging fitting 6 nearby, please turn the side of the display board 1 marked with the word "open" as shown in Figure 6. Turn to the front. Then, the surface of display board 2 marked with the word "open" also faced up, and the surfaces of both display boards 1 and 2 marked with the word "closed" joined each other on the back. Therefore, no matter which direction the display boards 1 and 2 face, it is displayed that the valve is "open".

In this state, if you want to change the display to show that the valve is closed, turn over the display board 1 as shown in Figure 7, and open the exit of the hanging bracket 6 in a direction that is perpendicular or perpendicular to the width of the board. 8 and is turned over to the opposite side of the display panel 2. Then, the side of the display board 2 marked with the word "Closed" comes out, and the display board 1 moves the display board 2 so that the side marked with the word "Closed" comes out. polymerizes into
The surfaces of both display boards 1 and 2 marked with the word "open" are connected to each other on the back, so no matter which direction each display board 1 or 2 faces, the valve will be in the "closed" position. is displayed.

The present invention is not limited to the above-mentioned embodiments, and the shape of the display board, the connecting ring, and the material and shape of the hanging device can be changed as appropriate. Various characters, symbols, and other displays can be used depending on the status of equipment, equipment, etc. to be displayed.

Since the present invention is constructed as described above, one of the overlapping display boards is turned over, turned in a direction close to a long angle or perpendicular to the width of the board, and passed through the opening of the hanger to open the other display board. The display cannot be changed unless a complicated movement is applied to the display board, such as flipping it so that it overlaps with the opposite side of the board. It is impossible to give any movement to the display board, and it is possible to completely prevent the display on the display board from being changed by an external force that is not caused by an artificial force against the will of the person displaying the display.

Claims (1)

[Scope of utility model registration request] Two display boards each having different characters, symbols, or other markings on both sides of a board having a circular or other appropriate shape are arranged so that the board surface with the same markings faces the board surface. A connecting ring is loosely fitted into the through hole drilled in these plate pieces, and the connecting ring is connected to the hanging part and each display plate in a direction perpendicular or nearly perpendicular to the width of the plate. An indicator that is loosely fitted into an opening of a hanger having an opening that is open to the extent that it can be directed and passed through.
