識に関する。[Detailed explanation of the invention] [Industrial application field] This invention relates to statue road markings that are installed in an upright arrangement on paved roads for lane guidance and pedestrian/vehicle separation. The present invention relates to a road sign which is used as a guide road sign and which can be removed and replaced with a disk-shaped road sign during the snowy season so as not to hinder snow removal work.

要請されている。
Statue road signs are widely used on expressways for lane regulation and guidance purposes. In snowy countries and mountainous regions where snowfall lasts for a long period of time, statue road signs that protrude to a considerable height above the road surface are rarely installed at the center line of roadways because they obstruct snow removal work. However, from the viewpoint of smooth traffic and accident prevention, the use of statue road markings, which have a remarkable visual effect, is required during periods when there is no snowfall.
そのような要請に応たえるものとして、例え

59−108936号参照）。 In order to meet such demands, for example, as shown in FIG. The plate-shaped portion 6a and the pedestal 4
A metal fitting 6 consisting of a spiral cylindrical body 6b that protrudes further downward.
A buried tube 8 having an inner circumferential screw formed therein and removably screwed into the spiral tube body 6b is buried and fixed in the road surface, and apart from this pedestal and the sign body, a cover for the snowy season is provided. However, variable road signs are known that are selectively attached to buried tubes depending on the time of year (Jitsugan-Sho
59-108936).

業の邪魔となることがない。 With this variable road sign, the statue sign has a remarkable visibility effect outside the snowy season, making it possible to smoothly regulate lanes and provide guidance.In addition, the statue sign can be removed during the snowy season Can be replaced with road markings. This road marking is made of thin synthetic rubber (for example, iron rubber) and is fitted and fixed to the road marking. Therefore, it does not interfere with snow removal work.

However, in conventional variable road signs, the buried tube and the screw tube on the side of the statue sign body are screwed together without shock absorbing properties when strong kinetic energy is absorbed. When a traveling car collides with this road sign, there is a risk that the sign will break at the spiral portion due to the strong kinetic energy generated. This is because the kinetic energy at the time of a collision, for example, an instantaneous impact force of 20 tons/m is applied to the metal embedding legs.

ができる。 The pedestal in this invention integrally holds the above-mentioned figurine sign at its upper part, and has an attachment/detachment part protruding from its bottom surface. The shape and dimensions of this pedestal are arbitrary as long as they do not contradict the purpose of the pedestal. The material of this pedestal preferably has the same characteristics as the material of the marker. The attachment/detachment part of the pedestal consists of a metal spiral body in the center area of its outer periphery and a shock absorber that holds the spiral body. This cylindrical shock absorber is integrated with the pedestal main body, and preferably is formed integrally with the pedestal main body at the same time. The material of this buffer preferably has the same characteristics as the material of the marker and the base, and has the ability to disperse kinetic energy. Examples of such materials include hard or soft polyurethane. The metal spiral body is provided only in the central area of the outer periphery of this buffer body, and is not provided in the upper and lower areas of the outer periphery. A helical groove is cut on the outer periphery of the metal spiral body so that it can be removably screwed onto the fixed leg.

れた金属螺筒体によつて固定脚に固定される。 The pedestal that supports the sign at the top has a removable part that removably engages with fixed legs buried under the road surface, so the pedestal and sign can be removed during the snowy season, and can be removed during the snow-free season. A pedestal and a sign can be attached to it. If a car accidentally collides with this sign while it is installed,
Impact energy is propagated in the order of the sign, the upper part of the pedestal, the lower part of the pedestal, and the detachable part of the pedestal, but since this detachable part is then made up of the metal spiral body in the center area of the outer periphery and the impact buffer, the impact energy is The impact is dispersed by the shock absorber, so that it does not break at the pedestal part unlike conventional signs, and is fixed to the fixed leg by the metal spiral body provided on the outer periphery of the shock absorber.
