FIG. 1A is a view of a wing opening / closing truck loaded with the monitor suspension of the present invention as viewed from above, and FIG. 1B is a view of the wing opening / closing truck as viewed from the side.

  As shown in FIG. 1 (a), two rails 2 are arranged on the bottom plate 11 at a predetermined interval in parallel to a direction substantially perpendicular to the traveling direction of the vehicle and do not move due to impact or vibration. In this way, it is fixed to the bottom plate 11 via the rail fixing portion 31. In the present embodiment, the rails 2 are fixed to each other via the connecting portion 21, but the connecting portion 21 may not be provided.

A screw screw 33 is disposed on the bottom plate 11 so as to be substantially parallel to the rail 2, and is fixed to the bottom plate 11 via a screw fixing portion 32. The female screw portion 44 of the frame 4 shown in FIG. 1B is connected to the screw screw 33. When the handle 34 provided on the extension of the screw screw 33 is rotated, the frame 4 moves on the rail 2 via the female screw portion 44 by rotating the screw screw 33.
In this embodiment, a manual operation using the handle 34 is illustrated as a control mechanism for moving the frame 4, but it is needless to say that the operation is not limited to this and may be an electric operation using a switch or the like.

FIG. 1B shows a housing form when the frame 4 is mounted on the wing opening / closing type truck. At this time, the wing is closed and the frame 4 is stored in the cargo compartment 1. A metal suspension member 41 is attached to the upper portion of the frame 4 and is connected to a metal support 45 so as to be movable up and down.

It consists of a screw connection portion 46 disposed horizontally below, and a plurality of support posts 45 fixed vertically to the suspension member 41, the support connection portion 42, and the screw connection portion 46.
A wheel 43 is installed at the lower end of the column 45, and as shown in FIG. 2B, the wheel 43 can travel on a plurality of rails 2 arranged in parallel to the installation floor surface.
The screw connection portion 46 is formed with a female screw portion 44 for connection to the screw screw 33.
A motor M is installed in the screw connection portion 46. The motor M performs expansion / contraction of the support column 45 and rotation of the screw screw 33.

Explaining the expansion and contraction of the support column 45 by the motor M, the support column 45 includes an outer column 45x and an inner column 45y, and the inner column 45y can be stored inside the hollow outer column 45x. A screw screw (not shown) is provided inside the outer column 45x, and a screw receiving portion (not shown) that is screwed into the screw screw is provided inside the inner column 45y.
When the screw screw inside the outer pillar 45x is rotated by the motor M, the pillar 45 is expanded and contracted by extending the inner pillar 45y from the inside of the outer pillar 45x, and the height of the suspension member 41 can be adjusted. .

Next, the movement of the screw M 33 and the frame 4 in the front-rear direction by the motor M will be described.
When the frame 4 is moved along the rail 2 in the front-rear direction of the arrow shown in FIG. 2B, the screw M 33 is rotated by the motor M. As the screw screw 33 rotates, the connected male screw portion 44 moves, and the entire frame 4 moves on the rail 2 by the wheels 43 traveling on the rail 2.
The screw screw 33 may be rotated by rotating the handle 34 arranged on the extension of the screw screw 33 without depending on the motor M. In this case, the screw screw 33 rotates along with the rotation of the handle 34, the wheel 43 on the rail travels along with the movement of the connected male screw portion 44, and the entire frame 4 moves on the rail 2.
Whether the screw screw 33 is rotated by a motor or the handle 34 can be appropriately switched by a known means such as a switch.

FIG. 3 shows a wing opening and closing type truck on which the monitor suspension apparatus of the present invention can be installed.

The cargo compartment 1 includes a bottom plate 11, a wing 12, a rear door 13, a side door 14, and a front door 15. The wing 12 rotates upward about the fulcrum 16 and opens, whereby the stored cargo can be taken in and out. Note that the material of the door and wing constituting the cargo compartment 1 is metal, and the opening and closing operation of the wing can be operated from the driver's seat.

Next, an operation mechanism in which the monitor suspension device of the present invention is combined with a wing opening / closing type truck will be described with reference to FIG.
4A to 4C are views showing the relationship between the degree of opening / closing of the wing and the position and height of the frame when the wing opening / closing type truck is viewed from the rear. For convenience of explanation, the door located on the left side of the rear door 13 is omitted.

Fig.4 (a) is a figure which shows the time of 1st wing opening | release. At this time, the frame 4 is housed in a substantially central portion on the bottom plate 11, and the suspension member 41 is also positioned at the lower limit. Then, by pressing a switch (not shown) from the driver's seat or the like, the wing 12 of the truck starts to open.
Next, as shown in FIG. 4B, the wing 12 stops at the first stop position. This first stop position is a position opened approximately 45 degrees. Next, the operator moves the frame 4 along the rail 2 in the left direction in the figure by turning the handle or the like.

  At this time, the height of the suspension member 41 is gradually raised by driving the motor M, and a plurality of monitors D are installed on the suspension member 41. The monitor D can be mounted in a plurality of rows below, but the physical connection between the monitors can be connected using a known clasp or reinforcing member.

FIG. 4C shows a view when the wing 12 stops at the second stop position where the wing 12 is opened to the maximum.
At this time, the frame 4 is located on the left side in the drawing on the rail 2, and the suspension member 41 is also located at the maximum height. Regarding the installation of the monitor D, as in the case of FIG. 4B described above, the suspension member 41 is gradually raised and a plurality of monitors D are appropriately connected.
Here, examples of the plurality of monitors D suspended from the suspension member 41 include known LED display panels, liquid crystal panels, and organic EL panels. A video signal is transmitted from a control box (not shown) to each panel. The assembled large display receives the video signal and displays a large video.

In the embodiment shown in FIG. 4, the operation of the wing 12, the movement operation of the frame 4, and the lifting / lowering operation of the hanging member 41 have been described separately, but particularly when the control mechanism is electrically driven. These three movements may be related.
That is, the degree of opening / closing of the wing 12, the position of the frame 4, and the height of the suspension member 41 may be stored in association with a memory (not shown) and the respective states may be realized by a switch operation. For example, the position of the frame 4 and the suspension member 41 at the first stop position of the wing 12 is associated, and the position of the frame 4 and the suspension member 41 at the second stop position of the wing 12 is associated and stored. It is possible.

Moreover, it is good to set the movement limit of the flame | frame 4 and the raising / lowering limit of the suspending member 41 according to the opening / closing degree of the wing 12. FIG. More specifically, a movement range of the frame 4 and the suspension member 41 corresponding to the position of the wing 12 is defined in a memory or the like (not shown), and the frame 4 and the suspension member 41 do not operate beyond this movement range. Keep it like that.
According to this aspect, it is possible to prevent the frame 4 and the suspension member 41 from coming into contact with the wing 12 and being damaged.

  In addition, the stop position of the wing 12 mentioned above is not restricted to said example. For example, three or more stop positions of the wing 12 may be set, or the positions of the plurality of frames 4 and the heights of the suspension members 41 may be set for one wing stop position.

  Further, since the frame 4 is positioned below the top plate 112 or the side plate 111 of the wing 12, the wing 12 functions as a rain shield or a sun shade. For example, in an outdoor concert or a stage, it may be raining due to sudden weather changes, but the wing 12 stops at the first stop position, thereby preventing damage to the monitor suspended on the frame 4. be able to.

  FIG. 5 is a view when a plurality of monitors are suspended from a suspension member in the wing opening / closing type truck to constitute a large monitor. The state shown in FIG. 5 corresponds to, for example, FIG. 4C, and shows a state where the wings 12 are opened to the maximum, but it goes without saying that the monitor installation example is not limited to this example.

In FIG. 5, five monitors D (monitors D <b> 1 to D <b> 5) are suspended directly below the suspension member 41 via a known clasp 3. The shape and material of the clasp 3 are not particularly limited, and various members can be used as long as the monitor is fixed to the suspension member 41. Moreover, you may use the reinforcement member which connects the monitors D as needed.
As shown in the figure, a monitor D6 is physically connected below the monitor D1 and a monitor D7 is physically connected below the monitor D2 via a stopper 3.
Although FIG. 5 shows an example in which a total of 30 monitors D are connected, the number of monitors D can be adjusted according to the size used as a display.
Further, when the video signal is actually transmitted to the monitor D, the track is fixed by the hydraulic jack 5.

As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment and can be modified as appropriate.
For example, when the control mechanism is an electric mechanism, which controls the opening / closing of the wing, the movement of the frame, and the lifting / lowering of the suspension member, the frame is moved when it is detected that the wing has been opened to a predetermined height. Alternatively, the suspension member may be moved up and down.
In addition, even when the frame is moved or the suspension member is manually moved up and down using a handle, a brake may be automatically activated using a known brake device depending on the degree of opening and closing of the wing.

  The monitor suspension device according to the present invention is intended to make it possible to adjust the moving position of the frame 4 and the height of the suspension member 41 in accordance with the degree of opening and closing of the wing 12, and deviates from such a summary. The configuration designed in such a range belongs to the technical scope of the present invention.

  The present invention can be applied to a case where a plurality of monitors are suspended and used as a display, can reduce the work time, and can efficiently assemble and disassemble a large display. Therefore, the industrial applicability is extremely high.
