DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road signpost used for a center line of a road, a lane change line, a separation zone, and the like.

[0002]

2. Description of the Related Art On expressways and general roads, signs indicating a center line of a road, a lane change line, a separation zone, and the like are used.
Road signposts with hollow poles that recover after curving upon vehicle contact are widely used.

The above-mentioned road signpost comprises a pedestal fixed to the road and a signpost standing upright from the pedestal. The pedestal is formed integrally with the signpost, and the pedestal and the signpost are press-fitted or the like. Some are to be assembled. A pedestal formed integrally with a signpost is known as shown in Japanese Patent Publication No. 62-56282, and as shown in FIG. 4, the pedestal 2 is formed integrally with a cylindrical signpost main body 1. , Signpost body 1
Can be manufactured in a shape other than a straight shape, but in general, a sign pillar main body 1 having a straight shape is used from the viewpoint of cost. In a configuration in which the pedestal and the signpost are assembled by press-fitting or the like, for example, as shown in FIG. 5, the pedestal is divided into an outer peripheral pedestal 2-1 and an inner pedestal 2-2, and molded. 1 is provided at the lower end thereof with a widened portion 1a, which is press-fitted in a state of being clamped between the outer peripheral pedestal 2-1 and the inner pedestal 2-2. It cannot be applied to large-diameter road signs as shown in FIG. In FIG. 5, reference numeral 3 denotes an anchor bolt integrally connected to the inner pedestal 2-2, and reference numeral 4 denotes a buried leg buried in a road, which is shown in FIGS. 4 and 6 and an embodiment of the present invention described below. Although omitted, the pedestal is configured to be able to be fixed to the road surface by any method.

[0004]

According to the present invention, even if the shape of the signpost body is irregular as shown in FIG. 6, the signpost body can be easily and firmly attached to the pedestal. Road sign pillars will not be provided.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a road signpost comprising a pedestal and a signpost body, wherein the pedestal has a vertically divided structure of an upper pedestal and a lower pedestal, The lower end of the signpost body is sandwiched between the upper pedestal and the lower pedestal, and the pedestal and the signpost body are detachably connected to each other. It is characterized in that it is configured to be held.

Further, according to the present invention, a flange portion extending horizontally and a hanging portion bent downward from an edge of the flange portion are formed at the lower end of the hollow signpost main body, and the flange portion and the hanging portion are formed. The upper pedestal and the lower pedestal are formed with a vertical clamping portion for vertically clamping the flange of the signpost body and a left and right clamping portion for clamping the hanging portion from left to right. Is further divided into right and left parts, and is detachably fixed to the lower pedestal.

As described above, the road signpost of the present invention has a pedestal having an upper pedestal and a lower pedestal divided into two parts, and the lower end of the signpost main body is sandwiched between the upper pedestal and the lower pedestal. Attaching the pedestal and the signpost body detachably,
The upper pedestal is further divided into left and right parts so that the signpost body can be held by the upper pedestal, so even if the upper part of the signpost body is larger in diameter than the lower part, the signpost body and the pedestal can be extremely easily and reliably. It is possible to firmly assemble, so that the pedestal can be shared and the cost can be reduced, and in the event of damage, only the damaged part can be replaced to reduce the maintenance cost.

FIG. 1 is a block diagram showing an embodiment of the present invention.
3 will be described.

FIG. 1 is a side view showing an embodiment of the present invention.
FIG. 2 is a plan view, and FIG. 3 is a cross-sectional view showing a coupling structure between the pedestal and the signpost body. In these figures, reference numeral 1 denotes a cylindrical sign post main body, the upper part 1a having a larger diameter than the lower part 1b. 1c is a retroreflective member. Reference numeral 2 denotes a pedestal, which has a vertically divided structure of an upper pedestal 2a and a lower pedestal 2b, and the upper pedestal has a horizontally divided structure as described later.

As shown in FIG. 3, a flange 11 extending horizontally and a hanging portion 12 bent downward from the periphery of the flange are formed at the lower end of the signpost main body 1. The upper pedestal 2a and the lower pedestal 2b
A vertical holding portion 21 and a left / right holding portion 22 are formed, and as shown in FIG. 3, the vertical holding portion 21 holds the flange portion 11 of the signpost main body 1.
In a state where the hanging portion 12 of the signpost body 1 is clamped by the lateral clamping portion 22, the fixing screw 5 is tightened to tighten the upper pedestal 2.
When the a is fixed to the lower pedestal 2b, the signpost main body 1 can be securely fixed to the pedestal 2.

In the present invention, as shown in FIGS. 1 and 2, the upper pedestal 2a includes 2a-1 and 2a.
The upper and lower pedestals 2a-1 and 2a-2 are provided so that the lower end of the signpost body can be held in the left and right directions. Note that FIG.
, Reference numeral 51 denotes an upper pedestal 2 divided into two parts, left and right.
a is a fixing screw for fixing a to the lower pedestal 2b.

Although the above embodiment shows an example in which the upper pedestal is divided into two parts on the left and right, the present invention is not limited to such an embodiment. For example, a three-part or four-part structure may be used. Can also.

The sign post body 1 is made of an elastic material which can be bent and restored when it comes into contact with an automobile or the like, for example, an ethylene vinyl acetate polymer having the following physical properties.

Tensile strength: 23MPs (Test method: JIS Z1702) Elongation: 690% (Test method: JIS Z1702) Hardness: Durometer A85 (Test method: JIS K7215) Not limited to the above materials In addition to the above, resins such as polyethylene and polyurethane can also be used.

An upper pedestal 2a and a lower pedestal 2b
Is molded from a hard synthetic resin such as polypropylene having the following physical properties.

[0016] Tensile strength: 23MPs (Test method: JIS K6758) Elongation: 200% (Test method: JIS K6758) Hardness: Rockwell R scale 70 (Test method: JIS K6758) Instead of the above, a resin such as polyethylene or polyurethane can be used.

[0017]

As described above, according to the present invention, the pedestal is divided into an upper pedestal and a lower pedestal, and the lower end of the signpost body is sandwiched between the upper pedestal and the lower pedestal. The pedestal and the signpost body are detachably connected to each other, and the upper pedestal is further divided into right and left so that the signpost body is held by the upper pedestal. The upper part of the signpost body is shown in FIG. Even a large-diameter one can be manufactured without any trouble, so that the shape of the signpost main body can be arbitrarily changed.

Further, according to the present invention, even if the shape of the signpost body is changed, the pedestal can be used in common, so that an inexpensive road signpost can be provided. Therefore, in the event of damage, only the damaged part needs to be replaced, so that maintenance costs can be reduced.
