Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a road blocking device capable of displaying two different types of traffic signs such as blocking or guiding.

[Conventional technology]

Generally, as a device for shutting off a road, there are a flip-up type and a double door opening type in which a horizontal blocking rod is driven manually or by a machine.In particular, the latter is installed by installing a plurality of double door opening type circuit breakers. When operated sequentially, the regulation can be gradually applied.

[Problems to be solved by the device]

However, when traffic is regulated, visibility from a distance is required. Therefore, it is necessary to display a large blocking rod that constitutes the blocking device and a marking pattern such as an arrow. Were posted separately.

The present invention was devised in consideration of the usage status of the above-mentioned circuit breaker, and an object thereof is to provide a circuit breaker capable of integrally displaying a bar and a regulation display, which is particularly useful as a road sign. Is.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a road blocking device according to the present invention is provided with a plurality of vertical rails arranged in a horizontal direction in a laterally long rectangular frame body at regular intervals and at the same time. In order to be visible from a predetermined angle by the drawing set, horizontal division of the display of symbols or characters that can be visually recognized in the oblique side visual field of the frame on at least one side surface of each vertical bar. One of the above is drawn, and a vertical swivel axis is pivotally supported on a part of the frame, and the swivel axis is connected to a swivel drive mechanism to swivel the rectangular frame within a predetermined angle range in the horizontal direction. The gist is to displace the position.

Each of the vertical bars can be formed of a flat member having a wide side surface or a rod member having a triangular or trapezoidal cross section including a surface oblique to a surface orthogonal to the surface of the rectangular frame. Further, the blocking body can be configured by coloring the side edges of at least one of the front surface and the back surface of each vertical rail with a marker color.

[Action]

According to the above configuration, the display drawn on the surface of a large number of vertical bars arranged side by side in the frame differs depending on how the vertical surfaces of the vertical bars are viewed. Therefore, for example, by displaying "deadline display" on one surface of the vertical crosspiece and "guidance display" on multiple surfaces, it is possible to recognize a display having a different meaning by changing the angle facing the blocking device.

Further, the turning position of the frame body can be horizontally displaced within a predetermined angle range by the turning drive mechanism, and different displays can be repeatedly displayed for intermittent recognition.

[Embodiment] Hereinafter, a preferred embodiment of the road blocking device according to the present invention will be described with reference to the drawings.

1 to 3 show a first embodiment,
The breaker 1 corresponding to the conventional breaker includes upper and lower horizontal rods 2,2.
And the vertical rods 3, 3 at both ends, and a frame body having a width required for shut-off. A large number of vertical bars 4, 4 are evenly arranged side by side between the upper and lower horizontal rods 2, 2. is there. Each of the vertical bars 4 is
As shown in FIG. 2, the lateral direction (the thickness direction of the blocking body 1)
It is a wide and flat rod material. Further, 5 is such that a supporting rod 6 projecting laterally from one of the vertical rods 3 of the blocking body 1 is axially supported by a vertical swivel shaft 7, and the swivel shaft 7 is swung horizontally in a predetermined angle range. It is a swivel drive support device such as a swivel cylinder or a motor that is displaced in position.

In the barrier body 1 having the above-described structure, for example, by dividing and drawing the arrow 8 for supporting the direction on the left side surface of each vertical bar 4, 4, ..., At the 90-degree facing position shown in FIG. 3 (a), Since the arrow 8 cannot be seen, the horizontal rod 2, the vertical rod 3 and each vertical bar 4
By coating the surface on the front side of the above with a caution color with great visibility, it is possible to simply perform "blocking control". Again 45
At the tilted position, as shown in FIG. 3 (b), each vertical bar 4,
The portion of the arrow 8 drawn in 4 ... is continuously visible, and "direction regulation" can be performed.

4 and 5 show a second embodiment of the present invention.

That is, in this embodiment, the cross-section of each of the vertical bars 4, 4 ... Is formed into a triangle whose front side has an apex angle 4a, and is orthogonal to the rectangular frame surface of the blocking body 1 with the apex angle 4a sandwiched therebetween. It is composed of a surface 4b, an inclined surface 4c having an oblique receding angle smaller than the inclination angle of the circuit breaker, and a surface 4d parallel to the breaker 1.

For example, an arrow 8 is drawn on the orthogonal surface 4b of each of the vertical bars 4, 4 ... In the same manner as in the above-mentioned embodiment, and a black coloring 9 and a yellow coloring 10 are alternately applied to the inclined 4c, At the 90-degree facing position shown in FIG. 5 (a), the yellow and black stripes in which the black coloring 9 and the yellow coloring 10 of the sloping surface 4c alternately appear are visually recognized, and "blocking regulation" is performed. Like Further, at the 45-degree oblique position, as shown in FIG. 5 (b), the vertical bars 4, 4, ...
The portion of the arrow 8 drawn in FIG. 3 is continuously visible, and “direction regulation” can be performed.

In the road blocking device according to the present invention, the visible surface of the vertical bar 4 is changed according to the angle of the blocking body 1 to selectively visually recognize the display drawn on the surface. It goes without saying that the cross-sectional shape of the vertical rail 4 can be variously changed in design, as shown in the trapezoidal cross-sectional shape of FIG.

[Effect of device]

Since the road blocking device according to the present invention is configured as described above, the display drawn on the surface of a large number of vertical bars juxtaposed in the frame can be visually recognized selectively depending on the angle of the frame. For example, by displaying "deadline display" on one surface of the vertical rail and "guidance display" on the other surface, it is possible to perform two types of regulation.

In addition, if the frame is structured to be displaced in the swivel position in the horizontal direction within a predetermined angle range by the swivel drive mechanism, it is possible to carry out intermittent regulation repeatedly, and the practical effect after the present invention is extremely large. .
