[0020]
For example, as shown in FIG. 3, the marking device is used by fixing a base 1 to a carrier C attached to the roof of an automobile such as a truck T. Then, when moving, as shown by a two-dot chain line in FIG. 4, the support column 2 is laid down and folded. Further, as a power source for the electric motor 8, the rotating lamp 10, and the illumination lamp in the sign display unit 3, a battery mounted on a vehicle such as a truck T, a separately prepared battery, a generator, and the like are used.
[0021]
Here, the operation of the sign device will be described. That is, the marker device is shown by a two-dot chain line in FIG. 4 in a folded state. And in order to use this upright, first, the feed screw 5 (see FIG. 1) is rotated by operating the electric motor 8 (see FIG. 1), and the block body 6 (see FIG. 1) is moved backward. Move. At this time, the base side end of the link bar 4 moves backward from the front end in conjunction with the movement of the block body 6, and the roller 19 (see FIG. 5) at the end of the link bar 4 on the side of the label display unit is And the column 2 starts to rotate (stand up) together with the sign display unit 3. When the feed screw 5 continues to rotate, the base side end of the link rod 4 moves further rearward until it is stopped by the stopper 16 (see the one-dot chain line in FIG. 4). Move. If the rotation of the feed screw 5 continues even after the support 2 stops rotating, the base side end of the link bar 4 moves further back, and the sign display side end of the link bar 4 displays the sign. The part 3 is pushed up, and the sign display part 3 slides upward along the column 2 (see the solid line in FIG. 4). By this series of operations, the sign display unit 3 is positioned and held high in the standing posture.
[0022]
Next, the operation of the base 11 for fixing the rotating lamp 10 will be described. That is, from the state in which the marker device is folded as shown by a two-dot chain line in FIG. 5 until the support column 2 is stopped from rotating by the stopper 16 (see the one-dot chain line in FIG. 5), the base 11 is parallel. Performs a parallel movement of a quadrilateral four-bar chain mechanism. That is, the four sections are the line connecting the telescopic rod 24, the mounting portion of the telescopic rod 24 and the base 11 and the rotational shaft 21 of the base 11, the rotational shaft 21 of the base 11 and the rotational axis of the column 2. 13, and a line connecting the rotation shaft 13 of the support column 2 and the attachment portion of the telescopic rod 24 and the fixed piece 25. Of these four sections, the rotation shaft 13 of the support column 2, the extendable rod 24 and the fixed piece. A parallelogram four-joint rotation chain mechanism is formed by using a line connecting the attachment portion to 25 as a fixed node. Further, when the sign display unit 3 is slid upward after the rotation of the support column 2 stops, the telescopic bar 24 extends in conjunction with the slide length, and the base unit 11 moves in parallel. Thus, when the sign display unit 3 rotates and slides, the base unit 11 always performs a parallel motion, so that the rotating lamp 10 maintains an upright posture.
[0023]
When the sign device is folded, the sign display unit 3 and the column 2 follow the reverse process by rotating the feed screw 5 in the direction opposite to the above and moving the block body 6 forward. .
[0024]
Further, when the sign display part 3 slides up and down, the front part of the base part 11 is pulled by the tension spring 28 of the telescopic rod 24, so that the base part 11 is prevented from rotating backward. Yes. Note that the tension spring 28 may not be provided if there is no possibility that the base part 11 rotates backward due to the weight of the base part 11 itself or the rotating lamp 10 or the like.
[0025]
Thus, in the above-described embodiment, only the base side end of the link rod 4 is moved in the front-rear direction, that is, the feed screw 5 is rotated by the operation of the electric motor 8 and the block body 6 is moved in the front-rear direction. It is possible to raise the sign display unit 3 after raising the support column 2 together with the sign display unit 3, or to fall the support column 2 together with the sign display unit 3 after lowering the sign display unit 3. it can. In the meantime, the rotating lamp 10 can maintain a standing posture. The operation of the electric motor 8 is safe because it can be operated from the ground.
[0026]
Further, since the feed screw 5 used for moving the base side end of the link rod 4 also serves as a stopper mechanism and a brake mechanism, the indicator display unit 3 suddenly falls or the column 2 falls suddenly. It is safe.
[0027]
Further, since the sign display plate 17 is mounted on the front and rear surfaces of the sign display unit 3, when the sign display plate 17 stands up, not only to the driver of the vehicle traveling in the lane under construction. The sign display plate 17 can also be shown to the driver of the vehicle traveling in the opposite lane.
[0028]
In the above-described embodiment, as shown in FIG. 6 (the fixing piece 25 (see FIG. 1) and the like are omitted in FIG. 6) as an assist for raising the column 2, the torsion spring 29 is provided. It may be used. That is, a torsion spring 29 is inserted into the rotating shaft 13 of the support column 2, the lower ends of the left and right support columns 2 are connected by the frame material 30, and one end of the torsion spring 29 is locked to the frame material 30. While forming the stop piece 31, you may make it provide the latching shaft 32 which latches the other end of the torsion spring 29 between the support parts 14 of the base 1. FIG. Then, the torsion spring 29 is set so as to generate a large force for raising the column 2 when the column 2 is lying down, and not to apply the force when the column 2 is standing. By doing so, since the force to stand itself up acts on the support 2, the burden on the electric motor 8 is reduced, and a smaller electric motor 8 can be used. This is effective for saving power, reducing the weight of the marking device, and reducing manufacturing costs. The strength and the number of attachments of the torsion spring 29 are appropriately determined depending on the weight of the support column 2 and the sign display unit 3.
[0029]
Further, the base 1 may be provided with a lock mechanism as shown in FIG. 7 (the base 11 (see FIG. 1) and the like are omitted in FIG. 7). That is, a protrusion 33 is provided on the upper surface of the sign display portion 3, and a crank-shaped plate member 35 having a recess 34 engaged with the protrusion 33 formed at one end is rotatable to a frame material in front of the base 1. You may attach to. At this time, the other end portion where the recess 34 is not formed is positioned within the frame of the base 1 and the crank-shaped plate member 35 is tilted forward by a torsion spring or the like. The connecting pipe 7 is brought into contact with the connecting pipe 7 immediately before being positioned at the front end. When the connecting pipe 7 further moves forward, the sign display portion 3 rotates downward, and the crank-shaped plate member 35 also rotates. And if the connection pipe 7 is located in the front end, the recessed part 34 of the crank-shaped board | plate material 35 and the projection part 33 of the label | marker display part 3 will engage. On the other hand, when the connecting pipe 7 moves rearward, the crank-shaped plate member 35 falls forward and the engagement is released, and the sign display portion 3 rotates upward. With this mechanism, in the engaged state, the crank-shaped plate member 35 supports the weight of the tip portion of the sign display portion 3 and the like, and also prevents the sign display portion 3 from rattling or lifting, so that safety during travel is achieved. Is more secured.
[0030]
Furthermore, it is preferable that the sign display plate 17 can be easily attached and detached using a magnet or the like. By doing in this way, the safety | security of the attachment or detachment operation | work of the label | marker display board 17 used as a work in a high place becomes higher.
[0031]
Further, in a state in which the sign device is folded, the peripheral side surface portion and the upper surface portion of a portion other than the rotating lamp 10 may be covered with a cover. By doing so, the appearance of the marking device is improved and the marking device is protected during traveling.
[0032]
In the above embodiment, the electric motor 8 is used as the rotation drive unit. However, the present invention is not limited to this. For example, a universal joint provided at the rear end of the feed screw 5 and the universal joint are used. In addition, a long crank-shaped handle bar that can be rotated from the ground may be used. That is, the feed screw 5 may be rotated through the universal joint by engaging the tip of the handle bar with the universal joint and rotating the handle bar.
[0033]
【The invention's effect】
As described above, according to the marker device of the present invention, the marker display unit is erected integrally with the column by a simple operation of retracting one end of the link rod along the slide groove, and further along the column. Can be slid upward.
