Description

  The present invention relates to a road marking body having a function of preventing a vehicle from entering and a pedestrian from crossing.

  Installed in parks, public facilities, and other commercial facilities where people come and go to block or guide the entrance of vehicles, or installed along the sidewalk to prevent vehicles from entering or parked on the sidewalk Various inventions are disclosed for the road marking body.

  For example, Patent Document 1 discloses a fence pillar including a pillar core material 2 having a standing leg portion 2a at the lower end and an elastic buffer body 3 covering the core material 2, and the core. The height h of the material 2 is configured to be smaller than the set fence pillar height H, and an extension 3b extending from the upper end of the covering portion 3a covering the core material 2 to the upper end of the shelf pillar is formed on the elastic buffer body 3. A shelf which is integrally provided and the elastic buffer body 3 is attached to the core member 2 in a state where swinging displacement against the elasticity of the extension portion 3b with respect to the connecting portion with the covering portion 3a is allowed. Pillars are disclosed.

Japanese Utility Model Publication No. 03-018216

  FIG. 5 in Patent Document 1 discloses an embodiment in which the elastic buffer body 3 is formed in a U shape and is erected by legs 2 a provided at the respective ends. Since the shelf pillars and the beam parts are integrally formed to form a U-shape, the shelf pillars are completely damaged when partial damage occurs. There was a problem that had to be replaced.

  Accordingly, the present invention provides a road marking body in which a pillar portion and a beam portion can be easily attached and detached and parts can be exchanged.

In order to achieve the above object, the present invention is configured as follows.
That is, in the road marking body according to the present invention, at least two columnar marker portions having flexible poles that are elastically bent by contact with a vehicle are arranged in parallel, and the poles of the columnar marker portions are arranged in parallel. Has a beam-shaped sign that is detachably mounted,
Each of the poles includes a joint into which the beam end of the beam-shaped marker can be inserted,
Each joint is formed with a column side engaging portion,
A beam side engaging portion detachable from the column side engaging portion is formed at the beam end on both sides of the beam-shaped marker portion, respectively.
Each of the column side engaging portions and each of the beam side engaging portions are engaged with each other by rotation in one direction of the beam-shaped mark portion.

According to the road marking body according to the present invention, each pole is provided with a joint into which the beam end portion of the beam-shaped marker portion can be inserted, and each of the joints is formed with a column side engaging portion. Beam side engagement portions that can be engaged with and disengaged from the column side engagement portions are formed at the beam ends on both sides of the marking portion, respectively,
Since each column-side engaging portion and each beam-side engaging portion are engaged with each other by rotation in one direction of the beam-shaped marking portion, the beam-shaped marking portion is moved in the direction or By rotating in the opposite direction, they can be engaged and disengaged respectively, and the beam-shaped marker part and each column-shaped marker part on which it is installed can be easily attached and detached. Part can be exchanged.
In addition, since the columnar marker portion is provided with a flexible pole that bends elastically, each pole of each columnar marker portion on which the beam-shaped marker portion is installed when the beam-shaped marker portion is attached or detached. Can be easily bent and pulled apart in the opposite direction to increase the distance between them, and the beam-shaped marker can be easily attached and detached.

Further, the beam side engaging portion is formed with a protruding portion protruding radially outward on the outer peripheral side surface of the beam end portion,
The joint is provided with a support surface that supports the outer peripheral side surface of the beam end, a first recess that allows the protrusion to be inserted into the support surface from the end side, and the protrusion extending in the circumferential direction from the first recess. While constituting the pillar side engaging portion formed with a second recessed portion that can enter,
The second concave portions of the joints of the columnar marker portions arranged side by side are formed to extend from the first concave portions in the same circumferential direction, and the protrusions are formed by rotating the beam-shaped marker portions in one direction. If each of the second recesses is entered, even if a vehicle or the like comes into contact with the road marking body and a force that separates the column-shaped sign portions where the beam-shaped sign portions are installed works. The protrusion that has entered the second recess is brought into contact with the side edge of the second recess, and the beam-shaped marker and the column-shaped marker are not fixed.

In addition, a support surface that supports the outer peripheral side surface of the beam end portion is provided in the joint, and the pillar-side engagement portion is formed on the support surface with a protrusion protruding radially inward,
A first recess in which the protrusion of the joint is inserted from the end side and a second recess in which the protrusion can enter from the first recess are formed on the outer peripheral side surface of the beam end. While constituting the beam side engagement portion,
The second concave portions at the beam ends on both sides of the beam-shaped marker portion are formed to extend from the first concave portion in the same circumferential direction, and the projections are rotated by rotating the beam-shaped marker portion in one direction. If the vehicle enters each of the second recesses, a force such as a vehicle or the like comes into contact with the road marking body and pulls off the column-shaped sign portions on which the beam-shaped sign portions are installed works. This is also preferable because the protrusion that has entered the second recess is brought into contact with the side edge of the second recess, and the beam-shaped marker portion and the column-shaped marker portions cannot be fixed.

  According to the road marking body of the present invention, the columnar marker and the beam-shaped marker can be easily attached and detached, and the parts can be replaced.
