Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic sign (including a road sign) set on a road and a curve mirror.

[0002]

2. Description of the Related Art Since a traffic sign is usually fixed to a pole which is erected on the shoulder of a road, an automobile or a load hits a sign board and is often bent or turned sideways due to this impact. According to the investigation by the inventor of the present invention, this example is found in about 60% of traffic signs in shopping districts.

Therefore, as shown in FIG. 8, a fixing metal fitting 2 is attached to the pole 1, and the fixing metal fitting 2 and the supporting metal fitting 4 on the side of the marker plate 3 are stopped by a bolt 5 so as to be rotatable in the horizontal direction. When an object hits 3, the sign board 3 is bolt 5
There is a proposal of a traffic sign that is configured to rotate left and right around the center to prevent it from bending due to the impact, and then returning to the original position by the spring 6.

[0004]

However, the above traffic signs have the following drawbacks.

A. Since the sign board 3 escapes only in the horizontal direction, when an object hits the sign board 3 from the front side or the upper or lower part or the oblique part, the sign board 3 does not rotate and bends or remains in the lateral direction. Become.

B. Since the spring 6 is exposed, rust is generated in a short time due to rain or snow, and the signboard 3 cannot be restored.

An object of the present invention is to provide a highly durable traffic sign which rotates in a direction of 360 ° and escapes from an impact, does not rust on a movable part over a long period of time.

[0008]

The constitution of the present invention is as follows.

[0009] A support metal member having a mounting portion for the pole formed on the back surface, a forward-facing elastic plate attached to the upper and lower positions, and a supporting plate protruding from the outer side of the elastic plate at the upper and lower positions; It is attached to the support plate of the metal fitting so as to be rotatable in the horizontal direction, and at the rear up and down position, the projection is formed facing the elastic plate of the support metal fitting, and the fitting port is formed on the front side. A main body, a movable body formed by fitting a spherical portion from the inside into a fitting opening of the main body, and projecting a support rod in the horizontal direction; and a guide pin projecting from the main body toward the center, A twist restoring device formed by forming a V-shaped notch in the spherical portion of the movable body with which the guide pin engages, and a force in the pushing direction from the fitting port is applied to the movable body in the main body. Hold the movable body horizontally and Cult fitting spherical portion absorbs the load relief in the abutment, when the load is released and the spring applying a force to restore the movable member in the horizontal direction, consisting of traffic signs mounting bracket.

[0010]

When an object hits the marker plate or the mirror, the movable body only bends in the direction in which the object hits and absorbs the impact, because the spherical part is fitted in the fitting opening of the main body. Prevents the board from bending and damaging the mirror. On this occasion,
Depending on how it hits, the movable body is twisted, but this twist is absorbed by the V-shaped notch as it is as a twist, and when released from impact, the force of the spring applied to the movable body and the V-shaped The action of the notch and the guide pin restores the twisted movable body (sphere) to the original position before twisting.

Further, when the sign plate or the mirror is impacted by more than the horizontal bending angle of the movable body, the main body is mounted so as to rotate horizontally with respect to the support fitting.
This body rotates horizontally at an angle to absorb the bend. At this time, the projecting portion of the main body pushes the elastic plate and stores energy there, so that when the impact disappears, the main body pivots back to the original position due to the restoring force of the elastic plate. As a result, the sign plate or the mirror has a rotation angle obtained by adding the rotation angle of the movable body and the rotation angle of the main body, and there is no problem even for a large bending angle.

[0012]

EXAMPLE FIG. 1 shows a traffic sign mounting bracket according to the present invention. In this figure, reference numeral 10 is a triangular support plate 13 having a mounting portion 11 formed on the back surface for mounting with a gold band 12 to the pole 1, and protruding vertically to the front side.
3a and the supporting plate 1 as shown in FIG.
It is a support metal fitting in which U-shaped elastic plates 14 and 14a are attached to the inside of 3 and 13a so as to face forward.

Numeral 15 has a fitting opening 16 opened on the front side, and support shafts 17 and 17 are provided between the support plates 13 and 13a of the support fitting 10.
The elastic plate 1 is provided at a rear upper and lower position of the main body 15 so that the main body is attached so as to be rotatable in the horizontal direction by a.
Protrusions 18 and 18a that are in close contact with and are opposite to
Are formed.

Reference numeral 19 denotes a movable body in which a rear spherical portion 20 is fitted in the fitting opening 16 of the main body 15 and a mounting shaft 21 is projected on the front surface. A V-shaped notch 22 is formed, and the notch 2
In the center of 2, a guide pin 23 protruding from the main body 15 side
Are engaged. 24 is a spring for pushing the movable body 15 to the front side in the fitting opening 16 of the main body 15,
Reference numeral 25 is a sign plate (or mirror).

When the track or the like hits the marker plate 25 and a bending force acts on the marker plate 25, the mounting member first moves the movable body 1.
9 rotates in the fitting opening 16 of the main body 15 to absorb the bending force, and when the bending force disappears, the movable body 19 returns to the original position (direction) by the force of the spring 24. When a bending force exceeding the rotation angle of the movable body 19 acts,
The main body 15 rotates about the support shafts 17 and 17a of the support fitting 10, and at this time, the protruding portions 18 and 18a are elastic plates 14 and
14a is pushed in. This situation is shown in FIG.
By bending in steps, even if a large bending angle acts, it is absorbed. When the bending force of the main body 15 disappears, the elastic plate 1
It is restored to the original position (direction) by the restoring force of 4 and 14a.

Next, the up / down and left / right bending with respect to the sign plate 25 is absorbed by the rotation of the movable body 19, and the large left / right bending is further absorbed by the rotation of the main body 15, but the sign plate 25 is twisted. When it acts, a twisting force acts on the movable body 19, the spherical portion 20 is twisted, and the cutout portion 22 is pushed slightly rearward as shown in FIG. 5 and contacts the guide pin 23 at the inclined surface 22a, Then, when the twisting stops, the force of the spring 24 pushes it out as shown by the arrow a, so that it rotates in the direction of the arrow b along the inclined surface 22a and returns to its original position as shown in FIGS. 6 and 7. When returning, the twisting of the movable body 19 disappears.

[0017]

As described above, according to the present invention, since the mounting metal member is bent in two steps, it can be absorbed without a problem even in a large bending, and the sign plate, the mirror and the like are not damaged. Further, when a twist acts, the twist is absorbed and restored to the position before the twist, so that the sign plate and the mirror do not remain twisted (tilted).
