Next, with reference to FIG. 9, the fourth connecting member 25 of the second strut portion 2 and the second fixing member 33A of the fixing portion 3A will be described. FIG. 9 is a perspective view showing the lower part of the display installation device 100A. In FIG. 9, the column structure PT is omitted for simplification of the drawing.

As shown in FIG. 9, the fourth connecting member 25 connects a plurality of second strut members 21. Therefore, according to the second embodiment, the plurality of second support column members 21 can be further reinforced. In particular, in the second embodiment, the fourth connecting member 25 is arranged below the plurality of third connecting members 23 (FIG. 7). That is, the fourth connecting member 25 is arranged below the plurality of second strut members 21. Therefore, the strength of the plurality of second strut members 21 can be effectively improved by reinforcing the upper portion and the lower portion of the plurality of second strut members 21 by the third connecting member 23 and the fourth connecting member 25.

Other configurations of the fourth connecting member 25 are the same as the configuration of the second connecting member 15 described with reference to FIG. 4 and the like, and the description thereof will be omitted. Further, the positional relationship between the fourth connecting member 25 and the second strut member 21 is the same as the positional relationship between the second connecting member 15 and the first strut member 11 described with reference to FIG. Omit.

The second fixing member 33A is connected to the second connecting member 15 and the fourth connecting member 25 by, for example, a screw BS.

Then, the pair of second fixing members 33A, in cooperation with both the second connecting member 15 and the fourth connecting member 25, remove the pillar structure PT around the entire circumference of the pillar structure PT. Enclose. Therefore, the lower part of the plurality of first column members 11 and the lower part of the plurality of second column members 21 can be easily fixed to the column structure PT.

Specifically, the second fixing member 33A extends along the second direction D2 and has a substantially flat plate shape. Therefore, a substantially rectangular shape is formed by the pair of the second fixing member 33A, the second connecting member 15, and the fourth connecting member 25.

In addition, for example, the second fixing member 33A cooperates with one of the second connecting member 15 and the fourth connecting member 25, so that the column structure PT goes around the entire circumference of the column structure PT. May be enclosed. In this case, the second fixing member 33A has the same configuration as the second fixing member 33 according to the first embodiment.

Further, for example, the second fixing member 33A alone may surround the column structure PT over the entire circumference along the side surface of the column structure PT. In this case, the second fixing member 33A is wound around the pillar structure PT so that the first pillar member 11 and the second pillar member 21 are sandwiched between the second fixing member 33A and the pillar structure PT.

Next, the second display support member 6 will be described with reference to FIG. FIG. 10 is a perspective view showing the second display support member 6. In FIG. 10, the column structure PT is omitted for simplification of the drawing.

In particular, it is preferable that the plurality of second display support members 6 support the second display DP2 with the display surface of the second display DP2 facing diagonally downward. In addition, as in the first embodiment, it is preferable that the plurality of first display support members 5 also support the first display DP1 with the display surface of the first display DP1 facing diagonally downward. According to this preferred example, since the weight is well-balanced between the side of the first strut portion 1 and the side of the second strut portion 2, the display installation device 100A can be stably installed.

Specifically, the first display support member 5 supports the first display DP1 so that the back surface of the first display DP1 and the back surface of the second display DP2 face the second direction D2 with the pillar structure PT interposed therebetween. Then, the second display support member 6 supports the second display DP2.

The configuration of the second display support member 6 is the same as the configuration of the first display support member 5. However, the back surface of the second display DP2 (FIG. 6) is attached to the attachment surface 5a of the second display support member 6. Further, the first claw portion 5b of the second display support member 6 is hooked on the upper third connecting member 23. In addition, the second claw portion 5c of the second display support member 6 is hooked on the lower third connecting member 23. As a result, each of the plurality of second display support members 6 is supported by the plurality of third connecting members 23.

Then, the first variable mechanism 7 changes the height from the lower end to the upper end of the first strut member 11. In addition, the second variable mechanism 8 is arranged at a position between the upper end and the lower end of the second support column member 21 (FIG. 7). Then, the second variable mechanism 8 changes the height from the lower end to the upper end of the second support column member 21. Therefore, according to the third embodiment, the first display DP1 and the second display DP2 can be easily raised or lowered. As a result, labor during installation work and replacement work of the first display DP1 and the second display DP2 can be reduced.

In FIG. 11, the second variable mechanism 8 is hidden behind the column structure PT and cannot be seen, but the configuration of the second variable mechanism 8 is the same as that of the first variable mechanism 7. Further, the second variable mechanism 8 is driven in synchronization with the first variable mechanism 7 by, for example, a manual tool or a power tool. Therefore, the first variable mechanism 7 will be mainly described below, and the description of the second variable mechanism 8 will be omitted as appropriate.

FIG. 12 is a side view showing the display installation device 100B. FIG. 12 shows a state in which the first display DP1 is lowered by the first variable mechanism 7. In FIG. 12, the first display support member 5 and the column structure PT are omitted for simplification of the drawings.

The refraction movable portion 71 is refracted and movable by a plurality of movable joint portions 73. Specifically, the refraction movable portion 71 moves between the extended state and the refracted state. The extended state indicates a state in which the refracting movable portion 71 is linearly extended in the vertical direction VD along the first surface F1 (FIG. 11) of the column structure PT. The refracted state indicates a state in which the refracting movable portion 71 is refracted. Specifically, the refraction state indicates a state in which the refraction movable portion 71 is maximally refracted. FIG. 12 shows the refraction movable portion 71 in the refraction state, and FIG. 11 shows the refraction movable portion 71 in the extended state.

FIG. 13 is a perspective view showing the first variable mechanism 7. In FIG. 13, the refracting movable portion 71 in the extended state is shown. As shown in FIG. 13, the first variable mechanism 7 further includes an extended state fixing portion 78. The extended state fixing portion 78 fixes the refraction movable portion 71 so as to limit the refraction operation of the refraction movable portion 71 in the extended state. Therefore, according to the third embodiment, it is possible to prevent the refraction movable portion 71 from changing from the extended state to the refracted state after the first display DP1 and the second display DP2 are raised and installed.

The upper connecting member 14 is fixed to the lower ends of the plurality of upper strut members 111. The lower connecting member 16 is fixed to the upper ends of the plurality of lower strut members 112. Similarly, the second strut portion 2 further includes an upper connecting member 14 and a lower connecting member 16.

The first variable mechanism 7 is arranged between the upper connecting member 14 and the lower connecting member 16. Then, the upper part of the first variable mechanism 7 is connected to the upper connecting member 14, and the lower part of the first variable mechanism 7 is connected to the lower connecting member 16.

Specifically, the first variable mechanism 7 is a pantograph jack mechanism. Therefore, the height from the lower end to the upper end of the first strut member 11 can be changed by a simple configuration. Similarly, the second variable mechanism 8 is also a pantograph jack mechanism. Therefore, the height from the lower end to the upper end of the second strut member 21 can be changed by a simple configuration.

Since the first variable mechanism 7 is a pantograph jack mechanism, the first variable mechanism 7 has the following configuration. That is, the refraction movable portion 71 includes a pair of first arms 711 and a pair of second arms 712. The pair of second arms 712 are arranged above the pair of first arms 711. Further, the plurality of movable joint portions 73 include a pair of shaft members 730, a pair of shaft members 731, and a pair of shaft members 732. Further, the first variable mechanism 7 further includes a base 75, a pedestal 77, and a pair of shaft support members 74.

And concatenate. Specifically, one end of one of the first arm 711 of the pair of first arms 711 and one end of the second arm 712 of the pair of second arms 712 are among the pair of shaft members 730. It is rotatably connected by one of them. Further, one end of the other first arm 711 of the pair of first arms 711 and one end of the other second arm 712 of the pair of second arms 712 are formed by the other of the pair of shaft members 730. It is connected so that it can rotate.

Each of the pair of shaft members 730 is supported by the pair of shaft support members 74. Each of the pair of shaft support members 74 is fixed to one end of the pair of first arms 711.

The pair of shaft members 731 connects the pair of first arms 711 to the base 75 so that the pair of first arms 711 can each rotate around the pair of shaft members 731. The base 75 is connected to the lower connecting member 16.

The pair of shaft members 732 are connected to the pedestal 77 so that the pair of second arms 712 can each rotate around the pair of shaft members 732. The cradle 77 is connected to the upper connecting member 14.

As shown in FIG. 13, the extended state fixing portion 78 includes a first extended state fixing member 79 and a pair of second extended state fixing members 80. Then, in the first variable mechanism 7, when the refraction movable portion 71 is in the extended state, the first extended state fixing member 79 is attached to the lower end portions of the pair of second arms 712. In the third embodiment, the first extended state fixing member 79 extends along the first direction D1 and has a substantially flat plate shape. Specifically, one end of the first extended state fixing member 79 is connected to the lower end of one of the second arm 712 of the pair of second arms 712. The other end of the first extended state fixing member 79 is connected to the lower end of the other second arm 712 of the pair of second arms 712. Therefore, it is possible to prevent the refraction movable portion 71 from changing from the extended state to the refracted state after the first display DP1 and the second display DP2 are raised and installed.

Each of the pair of second extended state fixing members 80 extends along the second direction D2 and has a substantially flat plate shape. The second extended state fixing member 80 is connected to the first arm 711 and the second arm 712 so as to straddle the boundary between the first arm 711 and the second arm 712. Therefore, it is possible to further prevent the refraction movable portion 71 from changing from the extended state to the refracted state after the first display DP1 and the second display DP2 are raised and installed.

Further, the second extended state fixing member 80 is connected to the first arm 711 and the second arm 712 so as to straddle the boundary between the first arm 711 and the second arm 712 of the second variable mechanism 8. Therefore, it is possible to prevent the refraction movable portion 71 of the second variable mechanism 8 from changing from the extended state to the refracted state after the first display DP1 and the second display DP2 are raised and installed.

Further, the second extended state fixing member 80 connects the first arm 711 and the second arm 712 of the first variable mechanism 7 and the first arm 711 and the second arm 712 of the second variable mechanism 8. Therefore, it is possible to effectively prevent the refracting movable portion 71 of the first variable mechanism 7 and the second variable mechanism 8 from changing from the extended state to the refracted state.

Next, the first variable mechanism 7 will be described in more detail with reference to FIGS. 14 and 15. FIG. 14 is a perspective view showing a part of the first variable mechanism 7. In FIG. 14, the state of the refraction movable portion 71 is an extended state. FIG. 15 is a perspective view showing a pair of shaft members 730 and a pair of mounting members 803.

The shaft unit 85 includes a screw shaft member 801, a pair of mounting members 803, a pair of stoppers 805, a first nut 807, a second nut 809, and a third nut 811. The first nut 807 corresponds to an example of a “screw”.

The screw shaft member 801 has a substantially rod shape and is a male screw extending along the first direction D1. The screw shaft member 801 is attached so as to straddle the pair of shaft members 730. The first nut 807 is a female screw. The first nut 807 is screwed into the screw shaft member 801 and the distance between the pair of shaft members 730 is adjusted by tightening and loosening the screw shaft member 801.

The pair of mounting members 803 attaches the screw shaft member 801 to the pair of shaft members 730. When the first arm 711 and the second arm 712 extend linearly along the column structure PT (that is, in the extended state of the refracting movable portion 71), at least one of the pair of mounting members 803 is a screw shaft member. It is removable from 801 and the screw shaft member 801 is removable from the pair of shaft members 730 in a state where at least one of the pair of mounting members 803 is removed from the screw shaft member 801. Therefore, according to the third embodiment, the screw shaft member 801 having a relatively long length can be removed from the first variable mechanism 7. As a result, it is possible to prevent the screw shaft member 801 from becoming an obstacle to people around the display installation device 100B.

Here, each of the pair of shaft members 730 is supported by the pair of mounting members 803.

The shaft member 730 extends along the second direction D2.

As shown in FIGS. 14 and 15, after the shaft member 730 is attached to the notch 813, the stopper 805 is fixed to the first wall portion 9 so as to straddle the notch 813. As a result, it is possible to prevent the shaft member 730 from coming off the mounting member 803.

The screw shaft member 801 penetrates a pair of mounting members 803. Specifically, the screw shaft member 801 penetrates through the through hole 815 (FIG. 15) of the pair of second wall portions 4.

The screw shaft member 801 has a first end portion E1 and a second end portion E2. The first end portion E1 indicates one end portion of both end portions of the screw shaft member 801 in the first direction D1. The second end portion E2 indicates the other end portion of both end portions of the screw shaft member 801 in the first direction D1.

Hereinafter, the first wall portion 9 and the second wall portion 4 on the side of the first end portion E1 of the screw shaft member 801 may be described as the first wall portion 9a and the second wall portion 4a, respectively. The mounting member 803 on the side of the first end portion E1 of the screw shaft member 801 may be referred to as a mounting member 803a. Further, the first wall portion 9 and the second wall portion 4 on the side of the second end portion E2 of the screw shaft member 801 may be described as the first wall portion 9b and the second wall portion 4b, respectively. The mounting member 803 on the side of the second end portion E2 of the screw shaft member 801 may be referred to as a mounting member 803b.

A first nut 807 is non-rotatably fixed to the outer surface of the second wall portion 4a. In the third embodiment, the first nut 807 is welded and fixed to the outer surface of the second wall portion 4a. Then, the screw shaft member 801 is screwed into the first nut 807.

A second nut 809 is non-rotatably fixed to the second end E2 of the screw shaft member 801. In the third embodiment, the second nut 809 is welded and fixed to the second end E2. The second nut 809 faces the outer surface of the second wall portion 4b. Further, the third nut 811 is screwed into the screw shaft member 801. The third nut 811 is a female screw. The third nut 811 faces the inner surface of the second wall portion 4b. The distance between the second nut 809 and the third nut 811 is maintained at a predetermined length with the second wall portion 4b interposed therebetween. At the second wall portion 4b, the screw shaft member 801 runs idle.

Next, an example of a method of removing the shaft unit 85 from the first variable mechanism 7 will be described with reference to FIG. First, the third nut 811 is loosened to increase the distance between the third nut 811 and the second nut 809. Next, the screw shaft member 801 is rotated to remove the screw shaft member 801 from the first nut 807. Next, the stopper 805 of the first wall portion 9b of the mounting member 803b is removed. Next, the mounting member 803b with the screw shaft member 801 attached is pulled out from the shaft member 730. Next, the stopper 805 is removed from the first wall portion 9a of the mounting member 803a. Next, the mounting member 803a is pulled out from the shaft member 730. As a result, as shown in FIG. 13, the shaft unit 85 is removed.

(Modification example)
The display installation device 100C according to the modified example of the third embodiment of the present invention will be described with reference to FIG. The modified example is mainly different from the third embodiment described with reference to FIGS. 11 to 15 in that the modified example has the shaft holding member 90 instead of the shaft unit 85. Hereinafter, the points that the modified example differs from the third embodiment will be mainly described.

FIG. 16 is a side view showing the first variable mechanism 7A of the display installation device 100C according to the modified example of the third embodiment. As shown in FIG. 16, the display installation device 100C includes a first variable mechanism 7A. Although not shown in FIG. 16, the display installation device 100C includes a second variable mechanism 8A. The first variable mechanism 7A and the second variable mechanism 8A face each other in the second direction D2 via the column structure PT. The configuration of the second variable mechanism 8A is the same as the configuration of the first variable mechanism 7A, and the description thereof will be omitted. The first variable mechanism 7A corresponds to an example of a "variable mechanism".

The first variable mechanism 7A includes a shaft holding member 90 in place of the shaft unit 85 according to the third embodiment described with reference to FIG.

The shaft holding member 90 holds a pair of shaft members 730. Specifically, the shaft holding member 90 is in a state in which a pair of first arms 711 and a pair of second arms 712 are bent with respect to the column structure PT and extend linearly along the column structure PT. In the process of operating in the changing direction UD, the pair of first arms 711 and the pair of first arms 711 and the pair of second arms 712 are restricted from operating in the direction LD opposite to the direction UD. The posture of the two-arm 712 is maintained stepwise. Therefore, according to the modified example, it is possible to reduce the labor during the work of changing the refracting movable portion 71 from the refracted state to the extended state. For example, the direction UD indicates a vertically upward direction, and the direction LD indicates a vertically downward direction.

Specifically, the shaft holding member 90 holds one of the pair of shaft members 730, the shaft member 730, at one end of the shaft holding member 90 in the first direction D1. Further, the shaft holding member 90 includes a holding portion 91. The holding portion 91 is substantially serrated and extends along the first direction D1. That is, the holding portion 91 includes a plurality of recesses 92 arranged along the first direction D1. The other shaft member 730 of the pair of shaft members 730 fits into the recess 92. Therefore, in the process of operating in the direction UD in which the pair of first arms 711 and the pair of second arms 712 change from the state of being refracted with respect to the column structure PT to the state of extending linearly along the column structure PT. , The movement of the pair of shaft members 730 in the direction in which the distance between the pair of shaft members 730 is widened is restricted. As a result, the postures of the pair of first arms 711 and the pair of second arms 712 can be maintained stepwise in the process of changing the refraction movable portion 71 from the refraction state to the extension state.
