Further, since the link frame 2 is attached to the front side of the support 1 and the operation rod 42 is disposed on the rear side of the support 1, the operation of the operation rod is easy and the human eye can see it. Good appearance on the front side. Further, the link frame 2
At the time of the maximum expansion of, and at night, the illuminator 62 is lit (regardless of whether or not automatic operation is performed), so that the sign can be visually recognized even at night. Further, since a square pipe is used as the support, positioning and prevention of rotation are prevented, and the weight is light.

Embodiment 2 The marker of this embodiment is shown in FIG. 9 (when the link frame is folded).
As shown in FIG. 10 (when the link frame is expanded), a roll winding body 3A capable of freely winding and rewinding the marker sheet 3 is provided. That is, one end of the sign sheet 3 is fixed to the outer periphery of the cylinder 72, and the sheet 3 is wound around the outer periphery of the cylinder 72 to constitute a rolled body 3A. Note that the other end of the marker sheet 3 is attached to a fixed shaft 74 having a cylinder of the same size as the roll wound body on the outer periphery. And
In this roll winding body 3A, one end of a spring (which may have an appropriate natural length) arranged in the cylinder 72 is connected to the fixed shaft 71, and the other end is connected to the inner surface of the cylinder 72. The sign sheet 3 is wound up by the restoring force of the spring 73. The fixed shafts 71 and 74 are attached to the vertical bar 22 by the spring 7.
5 is carried out by the upper receiving member 76a in which the spring 5 is incorporated and the lower receiving member 76b in which the spring is not incorporated. However, one end of the sheet may be directly attached to the vertical bar 22 by a fixing method such as a screw. With the above configuration, the roll winding body 3
The fixed shaft 71 and the fixed shaft 74 of A are attached to the receiving fittings 76a and 76b of the vertical pipe 22 in the state shown in FIGS. 9 and 10 in a state where the spring 75 attached to the upper receiving fitting 76a is compressed. At this time, the roll winding body 3A is attached to the receiving fitting in a state where a torque is applied (a state in which a spring is wound).

As described above, the protruding sheet 3 is always wound up in accordance with the contraction of the link frame, and the sheet is always stretched. Therefore, the sheet is excellent in appearance, and the protruding sheet is easily stored and is very convenient, and the sheet is not blown out by wind. Further, it is very convenient because a rolled body of various contents can be attached and detached, and when the displayed contents change frequently, one sign can be used. In addition, without using a spring as described above,
It may be performed directly by hand or using a hand-wound handle or the like. In addition, the roll winding body 3A may be housed in a coating tube so that the figure of the roll winding body is not exposed to improve the appearance, or the roll winding body may be protected from the weather. In this case, the sheet-shaped body passage cutout groove is formed in the covering cylinder so that the sheet-shaped body can be unwound and unwound. Further, a cylindrical body is attached to one or both of the vertical rods, the rolled body is housed in this one cylindrical body, and one end of the sheet-like body is hooked to another cylindrical body or the vertical cylindrical body. Etc. can be adopted. Also in this case, the sheet-shaped body passage cutout groove is formed in the predetermined cylindrical body.

It should be noted that the present invention is not limited to the specific embodiments described above, but may be variously modified within the scope of the present invention in accordance with the purpose and application. For example,
As shown in FIG. 12, the apparatus may not be provided with the above-mentioned enlargement / reduction means or electric enlargement / reduction means. In this case, when the link frame 2 is expanded or folded, a stopper for fixing its position [for example, 9a and 9 in FIG.
The stoppers b (when expanded) and the stoppers 9c and 9d (when folded) are to be attached when it is to be fixed, regardless of the structure of the stopper, the mounting position, etc., and the link frame 2 moves. In this case, a person can be folded, but the structure is simpler, so that the number of failures is reduced and the cost is reduced.

In the case of folding, in the above description, the link frame is pushed down, but it may be pushed up. Further, as means for coating the sheet-like body, other than the above, for example, a cover sheet is attached to one of the vertical pipes with a hook, a button, or magic tape or the like, and further turned around to cover the sheet-like body. Alternatively, the other end of the cover sheet may be covered and fixed with a hook, a button, a belt, a chain, a magic tape, or the like. Further, a support base (weight) into which the lower end of the support body can be inserted and removed can be provided.

The link frame body may be expanded and folded manually instead of manually. As this electric expansion / contraction means, a known means can be used. FIG. 13 shows an example of the electric enlarging / reducing means. That is, the electric expansion / contraction means 4 ′ includes a motor 482 installed inside the hollow of the support 1 and having the screw shaft 481 attached thereto, and a box 483 that slides up and down as the screw shaft 481 rotates. The box 483 is connected to the link frame 2 via the guide groove 44 on the front surface side of the support 1.
4 and the link frame 2 is rotatable.
The motor drive portion includes an operation switch (not shown), two limit switches 486a and 486b for detecting top dead center and bottom dead center of the box 483, a motor 482, a power supply, and a controller to which all of the above components are connected. 485. The screw shaft 481, the box 483, and the motor 4
82 and the like may not be arranged inside the support 1 but may be arranged outside.

This operation is as follows. That is, when the operation switch is turned on, the motor 482 starts rotating, and when the box body 483 slides to the top dead center, it is detected by the limit switch 486a installed at the top dead center position inside the support, and the motor is transmitted via the controller 485. The rotation of 482 is stopped. At this time, the link frame 2 expands, and the entire area of the sign sheet is stretched. When the operation switch is turned on again, the motor 482 starts rotating in the opposite direction to the above,
When the box body 483 slides to the bottom dead center, it is detected by the limit switch 486b installed at the bottom dead center position inside the support, and the rotation of the motor 482 via the controller 485 is stopped. At this time, the link frame 2 contracts, and the sign sheet is folded. In this case, although a power source is required, no manual operation is required and remote operation is possible. Any place where a power supply can be secured is convenient, and a battery may be used. In this case, the operation switch may be turned on by remote control by wire or wirelessly. In the case of performing this remote control, it is not necessary to cross the road when the sign is installed on the road, especially on the median strip side of the highway, and it is extremely safe.

Further, as shown in FIG. 14, a bellows-like link frame may be used. In this case, the rod is expanded and contracted right and left, and the rod-shaped body (rod) 211 on the center side is fixed to the support 1 by fixing pins P ₁ and P ₂ . Since this shows a relatively planar link frame shape, the frame is less bulky when expanded and folded. And
Also in the marker using the bellows-like link frame, similarly to the above, the marker sheet is wound and wound.
It is also possible to use a roll that can be rewound or a cartridge-type roll that can be freely attached and detached.

Further, as the above-mentioned sign sheet, for example, a structure in which a large number of appropriately sized holes (including irregularly shaped holes) or slits are provided in portions other than figures to provide ventilation. can do. In this case, the wind pressure is reduced, and even in a sudden strong wind, it is safe and lightweight. When used as a road sign, it is preferable to make this hole as small as 3 mm or less. This is because when this is large, night light from oncoming vehicles is allowed to pass, which may not be desirable.

[0033]

According to the marker of the first aspect of the present invention, when the link frame is expanded, a predetermined figure of the sign sheet can be visually recognized, and when the link frame is folded, it is easy to carry. At the same time, the wind pressure is significantly reduced, and the structure is simple. In the marker according to the second aspect of the present invention, since the link frame can be expanded and folded by the operation rod tube, the link frame can be easily expanded and folded easily and reliably.

According to the third invention, the link frame is expanded and
Since the link frame can be folded, the link frame can be controlled by remote control without any force and can be controlled by remote control, so that it is not necessary to carry the sign, thereby further improving safety. In the marker according to the fourth aspect of the invention, when the link frame is folded, the marker sheet is wound around the roll, so that the sheet has a good appearance and may be blown out by wind. Absent. In the marker according to the fifth aspect of the present invention, since the cartridge-type roll is used, the display items can be easily changed and the portability is excellent because the roll can be attached and detached (one place).
