In detail, the locking portion 62 has a concave surface 62a formed in a circular shape corresponding to a concave bottom surface recessed in a frustoconical shape, and an outer edge of the end wall 64 from the side edge of the concave surface 62a. And an inclined side surface 62b reaching the side surface.

FIG. 4 is a cross-sectional view showing a state where the engaging portion and the locking portion of the road marking body of FIG. 1 are engaged.
In the present embodiment, the difference between the shape of the coupling member 6a fixed to the end of the beam unit 5 and the coupling member 6b is a matter different from the marking unit 1B of the marking unit 1A.
Specifically, the coupling member 6a is formed in the same shape as the coupling member 6b except that the shape of the engaging portion 61 formed on the end wall 64 is different from that of the locking portion 62. It is fused and fixed to the beam portion 5 of the marking unit 1A.

  The engaging portion 61 of the coupling member 6a is formed such that the center of the end wall 64 of the coupling member 6b is formed in a convex shape protruding outward in a frustoconical shape, and the circle becomes smaller in diameter toward the outer side. Has been. Specifically, the engaging portion 61 corresponds to a convex end surface protruding into a truncated cone shape, and has a convex surface 61 a formed in a circular shape, and an inclined side surface extending from the side edge of the convex surface 61 a to the outer surface of the end wall 64. 61b.

  Further, the convex surface 61 a and the inclined side surface 61 b of the engaging portion 61 are formed in a shape corresponding to the concave surface 62 a and the inclined side surface 62 b of the locking portion 62. As a result, the beam portions 5 of the marking unit 1A, 1B are arranged to face each other, and the engaging portion 61 is housed in the locking portion 62 to be detachably engaged. 5 end portions can be combined to form one substantially inverted U-shaped road marking body.

  Since the convex engaging portion 61 is housed in the engaging portion 62 and is detachably engaged, when the vehicle contacts the road marking body and a large force is applied to the engaging portion, the engaging portion The engagement between 61 and the locking portion 62 is released, and the coupling between the beam portions 5 is released. As a result, the road marking body prevents the contacted vehicle from moving and causes a new accident.

  Moreover, although the engaging part 61 and the latching | locking part 62 of this embodiment are each formed in the truncated cone shape, if the edge part of each beam 5 can be couple | bonded, it will not restrict to this. For example, it may be formed into a triangular pyramid shape, a polygonal pyramid shape that is equal to or greater than a quadrangle, a polygonal pyramid shape, a conical shape, an elliptical cone shape, an elliptical frustum shape, or other shapes. When the joint portion receives an external force, if the shape is such that the force is not concentrated on the corners of the inclined side surface 61b and the inclined side surface 62b, the force is dispersed and the connecting members 6a and 6b are not easily destroyed. For this reason, the shape of the engaging portion 61 and the locking portion 62 is preferably a polygonal pyramid shape or a polygonal trapezoidal shape with rounded joints between adjacent surfaces, more preferably an elliptical cone shape or a conical shape, and an elliptical shape. A frustum shape, a truncated cone shape, and a hemispherical shape are more preferable.

Moreover, since the engaging part 61 and the latching | locking part 62 of this embodiment are each formed in the truncated cone shape, it is made so that it may become a small diameter, so that it may come first.
For this reason, the engagement between the engagement portion and the locking portion is released by an external force or the like as compared with a case where the tip and the root cross section are formed in a cylindrical shape or the like protruding and recessed to the same size. Sometimes, the engaging portion is not easily held by the locking portion. As a result, when a vehicle or the like contacts the road marking body and an external force is applied to the coupling portion of each beam portion 5, the engagement portion is held by the locking portion and is broken by an external force. Is suppressed.

  In the road marking body of the present embodiment, the coupling members 6a and 6b having different shapes are attached to and coupled to the marking unit 1A and 1B, respectively, but the coupling members 6a and 6b and the engaging portion 61 formed on these members. The configuration of the locking portion 62 is not limited to this. FIG. 5 is a sectional view showing another embodiment of the connecting member of the road marking body according to the present invention, and is a sectional view from a plan view. The coupling member 6 of the present embodiment is formed by arranging a convex engaging portion 61 and a locking portion 62 formed in a concave shape corresponding to the convex engaging portion 61 in parallel on one coupling member 6.
