SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an automatic door inspection work display tool installed on the floor at the time of automatic door inspection work, the upper ends of which are foldably connected to each other. A pair of vertical flat plates that can be leaned on the floor with the lower end side open, a connecting band interposed between the pair of vertical flat plates, and restricting the opening angle of these vertical flat plates, and can be placed on the connecting band. In addition, a structure is provided in which a display member indicating that the automatic door is being inspected is provided on the surfaces of the pair of vertically long flat plates.

In the present invention having the above-described structure, the lower ends of a pair of vertically long flat plates whose upper ends are connected to each other are opened, and the opening angle of these vertically long flat plates is restricted by the connecting band.
A weight member is placed on this connecting band. This allows the lower ends of the pair of vertically long flat plates to be opened during use and easily installed on the floor in front of the automatic door.Especially by placing the weight member on the connecting band even in the place where the wind blows Can be used in a stable state. In addition, since it is mainly composed of a pair of vertically long flat plates, it can be made compact and lightweight, and can be transported with the pair of vertically long flat plates folded.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a display device for an automatic door inspection according to the present invention.

FIG. 1 is a perspective view showing an automatic door inspection work display device according to an embodiment of the present invention, FIG. 2 is a front view of the display device of this embodiment, and FIG. 3 is a display device of this embodiment. FIG. 4 is a side view showing a state in which the display device of the present embodiment is folded, and FIG. 5 is a perspective view of a connecting band provided in the display device of the present embodiment.

An automatic door inspection display device 1 shown in FIG. 1 includes a pair of vertically long flat plates 2 and 3 made of synthetic resin, respectively.
It comprises a connecting band 4 interposed between the pair of vertically long flat plates 2 and 3 for restricting an opening angle of these vertically long flat plates 2 and 3, and a weight member 5 that can be placed on the connecting band 4. Yes,
The upper end 2A of the elongated plate 2 and the upper end 3A of the elongated plate 3 are foldably connected to each other, and the lower ends 2B, 3B of the elongated plates 2, 3 are connected via a connection band 4.

The vertically long flat plate 2 is made of a material that is used in an automatic door inspection work, for example, a yellow material, and is formed in a shape that becomes wider from the upper end 2A to the lower end 2B. An opening 2C for forming the handle 7 is provided. On the surface below the opening 2C, for example, a display character 6 indicating "I am troubled during the automatic door inspection" is provided. The same applies to the other vertically long flat plate 3, that is, a yellow material is used, the width is increased from the upper end 3 </ b> A toward the lower end 3 </ b> B, and an opening 3 </ b> C is provided. Display characters 6 are provided on the lower surface.

As shown in FIG. 3, the connecting band 4 includes a pair of connecting members 4A and 4C, an intermediate hinge member 4B for connecting these connecting members 4A and 4C to each other, and one connecting member 4A.
Hinge member 4D connecting A to lower end 2B of vertically long flat plate 2
And another hinge member 4E for connecting the other connecting member 4C to the lower end 3B of the vertically long flat plate 3. This connecting band 4 is attached to the vertically long flat plates 2 and 3 so as to be able to bend upward as shown in FIG. 3, and these vertically long flat plates 2 and 3 are completely folded as shown in FIG. Buried between the vertically long flat plates 2 and 3. In addition, the length of the connecting band 4 is set to a predetermined size that regulates the front-back opening angle θ between the vertically long flat plates 2 and 3 to a maximum of about 30 degrees.

In the display device 1 for inspection work of this embodiment, the vertically long flat plates 2 and 3 are stored in a closed state as shown in FIG. 4, and when used, as shown in FIG. The lower end 2 </ b> B side and the lower end 3 </ b> B side of the vertical flat plate 3 are opened in the front-rear direction, the vertical flat plates 2, 3 are leaned on the floor, and the weight member 5 is placed on the connecting band 4. At this time, when the connecting members 4A and 4C of the connecting band 4 are opened from the closed state to the horizontal state, the opening angle θ of the vertically long flat plates 2 and 3 becomes about 30 degrees.

In the display device 1 for inspection work of the present embodiment configured as described above, the lower end 2B side of the vertically long flat plate 2 and the lower end 3B side of the vertically long flat plate 3 are opened at the time of use, so that the front of the automatic door (not shown) can be easily viewed. Can be installed on the floor, especially
Even in a place where the wind blows, the weight member 5 can be placed on the connecting band 4 so as to be installed in a stable state.

Further, the display device 1 for inspection work according to the present embodiment.
In this example, the main structure is mainly composed of foldable synthetic resin vertically long flat plates 2 and 3 so that the weight is reduced and the total weight is reduced to about 1.2.
kg.
By completely folding as shown in FIG. 4, it is possible to achieve compactness without bulkiness during transportation,
Moreover, the maintenance staff can carry the indicating tool 1 with one hand by grasping the handle 7.

Further, the display device 1 for inspection work according to the present embodiment.
In this case, the vertical doors 2 and 3 are made of a saliva material, for example, a yellow material, and the automatic doors are displayed with characters 6 indicating that the automatic doors are being inspected. A passing person can immediately know that the automatic door is being checked.

In addition, the display device 1 for inspection work of the present embodiment.
Although the display characters 6 are provided on one surface of each of the vertically long flat plates 2 and 3, the display characters 6 may be further provided on both surfaces of each of the vertically long flat plates 2 and 3.

[0017]

As described above, according to the present invention,
It can be easily installed on the floor in front of the automatic door, and can be made compact and lightweight,
Therefore, there is an effect that a display device for inspection work of the automatic door which is convenient for the maintenance person of the automatic door can be obtained.
