Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a delineator (gaze guide) that also serves as a snow pole.

[Prior Art] Conventionally, this kind of thing is as follows.

Conventional products change the total length up and down depending on the amount of snow (two-stage type,
It can only be a three-stage type).

[Problems to be Solved by the Invention] The conventional techniques described above have the following problems.

If there is an impact from outside such as a work vehicle, it cannot be absorbed and is damaged.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide the following.

1. Prevent product damage when the above work vehicles collide. (Prevention of damage to products) 2. It is not necessary to take avoidance actions during work such as snow removal and mowing with work vehicles. (Improvement of Work Efficiency) [Means for Solving the Problems] In order to achieve the above object, the present invention is as follows.

That is, according to the present invention, in the column 2 in which the upper and lower reflectors 3 and 4 are attached to the upper and lower ends, the column 2 is composed of an upper vertical column 2A and a lower curved column 2B. 2B is composed of a bending strut unit 2B1 which is horizontally divided into a suitable number of stages, and the lower end of the upper vertical strut portion 2A and the upper end of the lower bending strut portion 2B are flexibly connected to each other to form an upper vertical strut. A connecting part between the lower end of the column 2A and the upper end of the lower bending column 2B, and a single bending column that is divided into an appropriate number of stages
The connecting portion between the lower end of the upper bending strut in 2B1 and the upper end of the lower bending strut is connected flexibly, and the upper end of the upper vertical strut 2A and the lower end of the lower bending strut 2B are connected. The space is a bending type delineator connected by a wire 8 passing through a through hole of the joint.

In this case, the connecting portion between the lower end of the upper vertical strut 2A and the upper end of the lower bent strut 2B and the separated bent strut unit 2B
The joint portions 6 of the lower end of the bending strut unit located above in 1 and the upper end of the bending strut unit located below in 1 are connected by joints 7, respectively, and the joint 7 is composed of an upper joint portion 7A and a lower joint portion 7B. , The upper joint portion 7A has a substantially V-shaped front surface on the lower surface of the cylindrical body 7A1,
In addition, the protrusions 7A2, which are formed into a substantially U-shaped side surface, can be arranged in series.

[Operation] Extension coil spring 8C built in when any pressure is applied to one of the bending strut bodies 2B1 in the bending strut portion 2B
Grows.

In this case, the lower end of the upper vertical strut 2A and the upper end of the lower bent strut 2B rub against each other in the front, rear, left, and right to freely bend.

In addition, the connecting portion 6 between the lower end of the bending strut unit located above and the upper end of the bending strut unit located below in the bending strut unit 2B1 also rubs forward, backward, leftward and rightward and freely bends.

When the pressure is removed, the tension coil spring 8C contracts and returns to its home position.

In this way, when a work vehicle or the like collides, the impact is absorbed and the product is prevented from being damaged.

Embodiments of the Invention Embodiments will be described with reference to the drawings.

Reference numeral 1 is a bending type delineator of the present invention.

Reference numeral 2 is a column having upper and lower reflectors 3 and 4 attached to its upper and lower ends.

Therefore, the pillar 2 is composed of an upper vertical pillar portion 2A and a lower bent pillar portion 2B, and the bent pillar portion 2B is composed of a bent pillar unit 2B1 which is horizontally divided into upper and lower parts.

(In the figure, the bending struts alone have three steps of upper, middle, and lower, but it is not limited to this and can naturally be increased or decreased depending on the state of the installation place.) In this case, the upper vertical struts The lower end of 2A and the upper end of the lower bent column 2B are flexibly connected.

Then, the lower end of the upper vertical support 2A and the bent support below
The connecting portion 5 with the upper end of 2B, and the connecting portion 6 with the lower end of the bending strut unit located above and the upper end of the bending strut unit located below in the bending strut unit 2B1 divided into upper, middle, and lower are joints 7, respectively. It is connected.

Therefore, the joint 7 is composed of an upper joint portion 7A and a lower joint portion 7B.

The upper joint portion 7A has a substantially V-shaped front surface on the lower surface of the cylindrical body 7A1.
The protrusions 7A2, which are V-shaped and have a substantially U-shaped side surface, are provided in series.

A through hole 7A3 is opened at the center of the upper joint portion 7A.

In addition, the above-mentioned front surface is the same direction as the longitudinal direction of the road on which the bendable delineator 1 of the present invention is installed.

The lower joint portion 7B has a hollow 7 in which a protrusion 7A2 on the upper joint portion 7A side is flexibly fitted on the upper surface of a cylindrical body 7B1.
B2 is engraved.

A through hole 7B3 is opened at the center of the lower joint portion 7B.

The joint 7 is made of a synthetic resin material or a metal material.

Therefore, the mounting state of the joint 7 will be described.

First, the lower end of the upper vertical strut 2A and the lower bent strut 2B
In the case of the connection part 5 with the upper end of the upper vertical strut 2A, the lower joint part 7B is provided at the upper end of the lower bent strut 2B while the protruding part 7A2 of the upper joint 7A projects at the lower end of the upper vertical strut 2A. It is fixed in an embedded state.

Then, in the bending strut unit 2B1 divided into upper, middle and lower parts, the upper joint portion is attached to the lower end of the bending strut unit located above.
The protruding portion 7A2 of 7A is fixed in a protruding state, and the lower joint portion 7B is embedded in the upper end of the bending strut unit located below.

The vertical column 2A on the upper side and the through hole 7A3 of the upper joint 7A on the curved column 2B on the lower side, which are continuously provided in this manner.
And the lower end of the wire 8 passing through the through hole 7B3 of the lower joint portion 7B is connected to the adjusting plate 8B provided on the lower surface of the bending strut portion 2B via the eyebolt 8A, and the upper end of the wire 8 is a tension coil spring 8C, It is connected to an adjustment plate 8F provided on the upper surface of the vertical column 2A via a shackle 8D, an adjustment bolt 8E and the like.

Roll it up with adjusting bolt 8E to make a single delineator.

In the figure, 9 is a well-known pole that supports a bending type delineator.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

1. When a work vehicle collides, the bending force absorbs the impact force to prevent product damage.

2. The work vehicle does not need to take evasive action, which improves work efficiency.
