Description

  The present invention relates to a cone-shaped sign having a triangular shape in front view, which is disposed at a construction site or a road-blocking site and used to alert a driver and prevent a vehicle from entering.

  Signs are generally used at construction sites and road closure sites to alert the driver and deter entry of vehicles. As such a marker, a hollow triangular pyramid marker formed of rubber is called a cone and is widely used.

  The sign called “cone” (hereinafter referred to as “cone-shaped sign”) has been widely used as a sign indicating the place where intrusion is restricted, since it has been used for various purposes in various places for many years. It can be said that. Therefore, the front-view triangle sign has the advantage that the viewer's implicit recognition can be used to indicate where intrusion is restricted.

  However, in order to prevent the corn-type marker from falling due to the wind, it is necessary to increase its weight and it is difficult to handle it by human power. Therefore, it is necessary to carry the operation tool in addition to the cone-shaped mark to the installation site, and in this case, two vehicles are required. Therefore, recently, a dedicated vehicle for installing and collecting a cone-shaped sign as disclosed in Japanese Patent Publication No. 7-623265 has been devised. On the other hand, since the cone-shaped mark is integrally molded, the shape becomes large. In this respect, there is a problem in the handleability. Therefore, in order to improve the handleability while maintaining the shape of the cone-shaped marker, the cone-shaped marker disclosed in Japanese Utility Model Laid-Open No. 5-38017 has been attempted to be folded. This foldable cone type sign has a structure that can be divided into a base plate and a sign part, and the sign part is composed of a support inserted into the base plate holder, a slide cylinder that is arranged around the support and slides around the support. And an open / close rod, and a marker sheet sewn on the outer periphery of the open / close rod, and is openable and closable. Therefore, it is possible to accommodate even a small space by folding the sign part, and there is an advantage that the carrying work to the arrangement site becomes easy.

  However, even with the folding cone type sign, the entire sign is prevented from falling by increasing its weight. In other words, the fall of the wind can be prevented by increasing the weight of the base plate that is separate from the folding sign. Therefore, the problem of handleability due to the large weight has not been solved. In addition to the installation of the base plate, it is necessary to attach the sign portion to the installation site, and there is a problem that the installation work is troublesome.

  Accordingly, an object of the present invention is to provide a cone-shaped mark that is lightweight, excellent in handleability, and does not fall over due to wind.

  The cone-type marker according to the present invention is composed of a column that stands up from the grounding portion and a marker plate that rotates around the column as an axis. The grounding portion has a protrusion on the grounding surface that engages with a hole in the paved road surface, and the sign board has an isosceles triangle or isosceles trapezoidal shape when viewed from the front.

  A plurality of the protrusions may be disposed in the vicinity of the edge of the grounding surface, and the grounding surface may be grounded via the protrusions to form a convex surface facing the ground.

  The cone type mark according to the present invention may include a restricting unit that stops the display surface of the sign plate in a predetermined direction and releases the restriction of the sign plate at a predetermined wind speed.

  Moreover, you may provide the generator which generates electric power using rotation of the said sign board.

  In the cone type sign according to the present invention, a sign plate whose front view is an isosceles triangle or an isosceles trapezoid is used to maintain an overview of the conventional cone type sign and indicate a place where intrusion is restricted. You can use the implicit perception of the intended viewer. And since the sign board rotates around the column that stands up from the grounding section, the wind force against the sign board is converted into a rotational force, so that no overturning moment is generated, and therefore the weight is not increased. It is possible to prevent the wind from falling over. Furthermore, since the ground contact portion has a protrusion on the ground contact surface that engages with a hole in the paved road surface, the shape of the paved road surface can be used and the stability can be improved without increasing the weight.

  In addition, if a plurality of protrusions are arranged near the edge of the grounding surface, and the grounding surface is grounded via the protrusion and forms a convex surface facing the ground, the lift force toward the ground due to the wind passing through the gap between the grounding surface and the ground Works, the installation force on the ground increases, and stability can be improved.

  Further, by providing a regulation means for releasing the regulation of the sign board at a predetermined wind speed by stopping the display surface of the sign board in a predetermined direction, when the wind is blowing, the sign board is allowed to rotate and falls. While preventing the wind, it is possible to convey the information on the display surface with the display surface directed in the direction in which the vehicle or person passes.

  Furthermore, by providing a generator that generates electricity using the rotation of the sign board, it is possible to prevent freezing and snow accumulation that impedes the rotation of the sign board with that power, and it can be used in winter in cold regions. It becomes.

It is a front view which shows the general view of embodiment of the cone-type label | marker which concerns on this invention. It is a top view of the cone type mark.

An embodiment of a cone-shaped marker according to the present invention is shown in the figure.
This cone-shaped marker is composed of a column 2 standing up from the grounding portion 1 and a marker plate 3 that rotates around the column 2 as an axis. The grounding portion 1 is made of a metal plate material, and a lower surface that is the grounding surface 11 is provided with a protrusion 12 that engages with a hole in the paved road surface. A plurality of protrusions 12 are arranged in the vicinity of the edge of the grounding surface 11, and the grounding surface 11 is grounded via the plurality of protrusions 12, and forms a convex surface 13 facing the ground at a central portion that is not grounded. The protrusion 12 is formed by fixing a member having a pointed head 12 a to the plate material of the grounding portion 1, and the convex surface 13 is formed by fixing a thin ball-shaped member to the plate material of the grounding portion 1. Further, the support column 2 is fixed to a surface opposite to the ground surface 11. The fixing method can be fixed by a known method such as welding or bonding with an adhesive. However, there is no restriction | limiting in the material of the earthing | grounding part 1, Concrete, rubber | gum, a synthetic resin, etc. may be sufficient, and the protrusion 12 and the convex surface 13 may be integrally molded in that case. Furthermore, when the material selected for maintaining the strength required for the ground contact portion 1 is too hard for the road surface, the surface of the protrusion 12 may be covered with another material. For example, when the protrusion 12 is made of metal, the pointed head 12a may be covered with rubber or synthetic resin.

  The sign board 3 is formed by molding a resin plate, and the shape in front view is an isosceles trapezoid. An insertion hole is formed at a position overlapping the axis of symmetry in front view, and the column 2 is inserted through this insertion hole. In addition, the diameter of the insertion hole is increased on the upper bottom side, and the generator 4 is inserted into the expanded diameter portion. Furthermore, a heating wire (not shown) is stretched around the sign board 3, and the generator 4 is connected to the heating wire.

  The display surface 31 of the sign board 3 has a yellow and black striped pattern for improving the visibility. However, the display content may be arbitrary on this surface, for example, an orange or the like that implies a conventional cone-type sign. It may be a single red color.

  A magnet 32 is fixed to the lower bottom side of the sign plate 3. On the other hand, on the upper surface of the grounding portion 32, the magnet 14 that makes a pair with the magnet 32 is fixed at a position facing the magnet 32 when the display surface 31 should face the direction. The force with which the magnet 14 and the magnet 32 attract each other is adjusted to such an extent that when a wind at a predetermined speed hits the sign plate 3, the magnet 14 and 32 constitute the regulating means in the present invention. ing.

  A handle 5 is fixed to the upper end of the column 2. The handle 5 makes it easy to carry the cone-shaped sign and prevents it from falling off the column 2 when the rotational speed of the sign plate 3 increases.

  According to this cone-shaped sign, by using the sign plate 3 whose front view is an isosceles trapezoid, it is possible to maintain an overview of the conventional cone-shaped sign and indicate a place where intrusion is restricted. The implicit perception of the person. And since the sign board 3 rotates centering on the support | pillar 2 which stood up from the earthing | grounding part 1, the force of the wind with respect to the sign board 3 is converted into rotational force (for example, white arrow line of FIG. 2), It is possible to prevent overturning due to wind without causing a falling moment, and thus without increasing the weight. Furthermore, since the ground contact portion 1 has the protrusion 12 that engages with the hole in the paved road surface on the ground surface 11, it is possible to improve the stability by utilizing the shape of the paved road surface without increasing the weight. Furthermore, since the ground contact surface 11 is grounded via the protrusion 12 and forms a convex surface 13 facing the ground, the lift force works toward the ground due to the wind passing through the gap between the ground contact surface 11 and the ground, and the ground contact surface 11 is installed on the ground. Power can be increased and stability can be improved.

  Furthermore, according to this cone-type sign, when the wind is blowing, the sign plate 3 can be allowed to rotate to prevent the tipping over. On the other hand, when there is no wind, the magnet 32 and the magnet 14 are attracted to each other so that the display surface 31 is predetermined. Therefore, the information on the display surface 31 can be conveyed in the direction in which the vehicle or person passes. However, since the display surface 31 is directed in a predetermined direction when there is no wind, the means for restricting the rotation of the sign plate 3 is not limited to a magnet. For example, a claw that is pushed back when a predetermined force is applied is provided in the groove. It is good also as a structure engaged with these.

  Furthermore, according to this cone type sign, the heating wire stretched around the sign board 3 can be heated by the electric power of the generator 4 to prevent freezing and snow accumulation that hinder the rotation of the sign board. Can be used in winter. In addition, when heating of a heating wire becomes unnecessary, it is good also as making a light-emitting means, such as LED, light-emit, and calling a vehicle or a person's attention.
