Abstract

PURPOSE:To absorb a sharp bent angle and a twist. CONSTITUTION:A main body 15 is installed in a support metal fitting 10 so as to be capable of making horizontal turning motion freely, and a movable body 19 is installed in the main body 15 so as to be capable of making turning motion freely, and they are constituted so as to be bent in two stages. A V shape notch part 22 is formed in a spherical body part 20 of the movable body 19, and a twist is reduced to its original position by means of a guide pin 23 and this notch part 22. Thereby, since this traffic control sign installing metal fitting can be bent in two stages, even if a sharp bend is applied, troubles are not caused, or even if a twist force acts upon it, it can be restored to its original condition, so that a traffic control sign is not left still in a twisted condition.

Description

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 plate, and the impact often causes the sign to bend or turn sideways. 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 signboard 3 is bolt 5
There is a proposal of a traffic sign that is configured to rotate to the left and right around the center to prevent it from being bent due to the impact, and then to return to its 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.

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

[0008]

The constitution of the present invention is as follows.

[0009] A support metal fitting 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, and the support. It is mounted rotatably in the horizontal direction with respect to the support plate of the metal fitting, and at the rear up and down position, the protrusion is formed facing the elastic plate of the support metal fitting, and the fitting port is formed on the front side. The main body, the spherical body is fitted from the inside into the fitting opening of the main body, the movable body is formed by horizontally projecting the support rod, and the guide pin is projected from the main body toward the center, A twist restoring device formed by forming a V-shaped notch in the spherical portion of a 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 the impact is released, the spring force 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. Therefore, when the impact disappears, the restoring force of the elastic plate causes the main body to rotate back to the original position. 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, 10 is a triangular support plate 13 having a mounting portion 11 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, 17 are provided between the support plates 13, 13a of the support fitting 10.
The main body 15 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 opposed to
Are formed.

Reference numeral 19 denotes a movable body in which the rear spherical body portion 20 is fitted in the fitting opening 16 of the main body 15 and the mounting shaft 21 is projected to the front surface. The lower surface of the spherical body portion 20 of the movable body 19 is A V-shaped notch 22 is formed, and the notch 2
In the center of 2, the guide pin 23 is projected 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 projecting portions 18 and 18a are elastic plates 14,
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, and the spherical body portion 20 is twisted so that the cutout portion 22 is pushed slightly rearward as shown in FIG. 5 and contacts the guide pin 23 at the inclined surface 22a, 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 the 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 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 twisting, so that the sign plate and the mirror do not remain twisted (tilted).
