Description

[Detailed description of the invention] (Industrial application field) This invention relates to various indicators and signs, and particularly to sign members that may lead to serious disasters due to display errors.

(Prior art) Figures 5A to 5F are general sign members that have been used for a long time, and are signs with the same characters, figures, etc. written on the surface or both sides of boards of various shapes. It is erected or affixed to a wall using hanging tools or appropriate adhesives. The one shown in Figure 6 is a display panel a that displays signs with opposite meanings (open and closed in the figure) at the same position on both the front and back sides of the board, and is suspended from the equipment by a hanging device c. When this display panel a is hung upside down,
It includes an opaque cover plate b that is large enough to completely cover either the top or bottom of the sign on panel a and is movable up and down. With this configuration, this sign member can be hung upside down and turned upside down. The consent indicator is now selectable.

(Problems to be solved by the invention) In any case, when changing the sign with the conventional sign members shown in FIGS. It was necessary. For the display panel shown in Figure 5, another sign member must be prepared for replacement, and for the display panel shown in Figure 6, it must be turned upside down, and the mounting location is high. If the device is placed in a large space or in a cramped space, it is troublesome to handle and operate.

This invention was made in view of these circumstances, and aims to provide an inexpensive sign member that is easy and reliable to change the sign, and is easy to handle.

(Means for Solving the Problems) The structure of the present invention made to achieve the above object will be explained based on the attached embodiment drawings.

Fig. 1 is an explanatory overall perspective view showing the installation state of the opening/closing display board, which is a typical sign member of this invention; Fig. 2 is a front view of the opening/closing display board; Fig. 3 is a side view of the same; The figure is a sectional view taken along the line -- in FIG. 2.

That is, the sign member of the present invention rotatably holds the rotary display board 3 between the pair of upper and lower holding plates 1 and 10,
A pair of independent display ranges 30, 31 are defined on the surface of the rotary display panel 3, and these ranges 30,
31, a pair of signs 301 consisting of letters, figures, etc.;
311, a rotation operation knob 32 is provided upright on the rotation display panel 3, and a protrusion 4 is fitted between the lower surface of the display panel 3 and the lower holding plate 10 in the thickness direction. It is arranged opposite to the receiving part 5, so that when the rotary display board 3 is rotated, one of the signs 30
1 or 311 are independently and selectively exposed between the upper and lower holding plates 1 and 10, and at this position, the protrusion 4 is fitted into the receiving part 5 to prevent rotation of the display panel 3. This is a characteristic feature.

(Function) FIG. 1 is a perspective view showing a state in which the indicator members of the present invention are used, and these indicator members are connected to a large number of fluid transport pipes P ₁ ,
It is hung from the outer periphery of P ₂ , P ₃ , and P ₄ .

According to this invention having the above-mentioned features, the display panel 3 is rotatably held between the pair of upper and lower holding plates 1 and 10, and there are no characters, figures, etc. on the surface of the rotary display panel 3. The first sign 301 is displayed in a pair of independent ranges 30 and 31.
When holding the holding plates 1 and 10 in your hand in the state shown in the figure and rotating the display panel 3 by pointing the rotary operation knob 32 erected on the display panel 3, only one sign 301 or 311 is turned. are independently and selectively exposed between the upper and lower holding plates 1 and 10. At this time, between the lower surface of the rotary display panel 3 and the lower holding plate 10, there is a protrusion 4 and a receiving part 5 into which the protrusion 4 fits in the thickness direction.
are arranged opposite each other, so by fitting the protrusion 4 into the receiving part 5 at this position, rotation of the display panel 3 is prevented, and only one of the indicators 301 or 311 can be independently and selectively displayed. It will be displayed.

To switch from one sign to the other, hold the holding plates 1 and 10 and use the operating knob 3.
2 to strongly rotate the rotary plate 3, the engagement force in the thickness direction between the protrusion 4 and the receiving part 5 is released, the rotary plate 3 is rotated to the new sign display position, and the protrusion 4 is rotated again. is fitted into the receiving part 5 and stopped at that position.

As described above, according to the present invention, by holding the operation knob 32 with the fingertips of the rotary disk 3 and rotating it in one direction or in the opposite direction, it is possible to select a desired sign.

(Example) The ones in Figs. 1 to 4 adopt a circular plate as the rotary display board 3, and the semicircular range is colored red and green to form display ranges 30 and 31, respectively, and a pair of upper and lower The retaining plates 1 and 10 are made of a synthetic resin integral plate, and the upper retaining plate 1 is approximately half the height of the lower retaining plate 10, and the display ranges 30 and 31 are marked with "closed" and "open" respectively.
Character signs 301 and 311 are displayed. This rotation display panel 3 is connected to the pivot 6 (bolt 60 and nut 6
1), the cross bolt-shaped rod 321, which is rotatably connected between the upper and lower holding plates 1 and 10 and serves also as the rotary operation knob 32 and the protrusion 4, penetrates the thickness of the display panel 3, and is screwed into the nut at the back. It is fixed at 322. As the receiving part 5, the above-mentioned character sign 301 or 311 connects the display range 30, 31 to the upper and lower holding plates 1,
The projections 4 are shown as a pair of receiving holes into which the protrusions 4 are fitted at corresponding positions that can be independently and selectively exposed between the holes. If the nut 61 of the pivot shaft 6 is tightened to a certain extent and a weak elasticity is applied to the tip of the protrusion 4 to bring it into rolling contact with the surface of the lower holding plate 10, when the protrusion 4 stands on the receiving portions 5, 5. It will fit naturally due to its elasticity and stop rotating, but when the operation knob 32 applies a rotational force that overcomes this fitting force by crossing, it will easily come off from the receiving holes 5, 5 and the display panel will be removed. 3 rotations are allowed. In this example, if the type of transportation fluid is indicated 7 in the margin of the upper holding plate 1, as shown in FIG.
This is very convenient because the relative relationship with 01 and 311 can be read at a glance, and this means that display 7 corresponds to which sign 3
This is because the choice of 01,311 is also unchanging.

The above is merely an embodiment of the present invention, and does not limit the present invention.
The protrusion 2 and the protrusion 4 may be separate from each other, and furthermore, it is possible to employ a spring means (not shown) for urging the protrusion 4 to fit into the receiving hole 5.
Of course, many other modifications may be adopted for the display range and the display mode of the sign.

(Effects of the invention) As is clear from the above structure and operation, the present invention eliminates the trouble of rehanging another sign or reversing the top and bottom every time the sign is changed, unlike conventional sign members. The operation is simple because the operation can be stopped at a predetermined position by simply rotating the rotation display panel in one direction or the opposite direction by operating the operation knob 32 in the current state and by fitting the protrusion and the receiving part. Moreover, it is accurate, the marking position does not shift even due to external force (vibration, impact, etc.), and it can be manufactured at a relatively low cost.

As described above, the present marking member is of great significance when applied to a wide range of industrial fields where safety management is highly recommended.
