Abstract

PROBLEM TO BE SOLVED: To provide a sign member which includes a fall prevention edge and which hardly causes the risk of falling even when a side surface of a sign part is subjected to a lateral load caused, for example, by being flapped in a wind from a direction perpendicular to the side surface.SOLUTION: A sign member 1 relating to the present invention includes a sign part 2 which is formed as a trigonal pyramid or a triangular truncated pyramid, and a flange part 3 which is elongated on the outside of the bottom 20 of the sign part 2 and installed on a ground surface. In the flange part 3, a fall prevention edge for preventing the sign member 1 from falling is provided on the outside of a corner 201 of a triangle of the bottom 20.

Description

  The present invention relates to a marking member installed on a road or the like.

  As marking members placed side by side at a traffic accident verification site, road construction work, electric wire construction work site, etc., for example, as shown in FIG. 9, a triangular pyramid sign portion 2000 and an outer portion of the bottom portion 2010 of the sign portion 2000 are extended. There was a marking member 1000 provided with a collar 3000 installed on the ground. Such a marking member is a flat surface on which the side surface 2020 of the sign part 2000 is easily visible because the sign part 2000 is not a cone or a truncated cone but a triangular frustum.

  This marking member 1000 has a circular edge 3010 formed on the outside of the triangle side of the bottom portion 2010 of the collar portion 3000, with a certain length away from the side, and bulging outwardly outside the corner of the triangle of the bottom portion 2010. An arcuate curved edge 3020 was formed (see Patent Document 1).

Japanese Utility Model Publication No. 7-20309

  When this marking member 1000 is installed on the road, it may receive a wind load. In particular, when a wind load is received from a direction perpendicular to the side surface 2020, the side surface 2020 receives wind force from the front, and thus the wind load cannot be released, and the curved edge 3020 of the bottom 2010 on the opposite side of the side surface 2020 As a fulcrum, the side 2020 side of the marking member 1000 sometimes floated. Then, the curved edge 3020 bulges outward, and the marking member 1000 is supported by a single point of contact with the ground at the curved edge 3020. Therefore, the marking member 1000 is in a posture against a natural wind whose wind direction and wind force constantly change. It was easy to break the balance, and there was a risk of falling.

  In addition, when a load other than wind (for example, a load caused by a person's foot hitting) is applied to the side surface 2020 from the front, it is supported by the ground at a single point of contact as in the case of receiving a wind load. After all, there was a risk of falling.

  The present invention was devised in view of the above-described problems, and has a triangular pyramid or triangular frustum marker portion, and receives a lateral load such as being blown by wind from a direction perpendicular to the side surface of the marker portion. Another object of the present invention is to provide a marking member that is less likely to fall over.

  In order to solve the above-described problem, the marking member of the present invention includes a marker portion that is a triangular pyramid or a triangular frustum, and a collar portion that extends outside the bottom portion of the marker portion and is installed on the ground. It is assumed that the configuration. Moreover, in the marking member of the present invention, the collar portion is provided with a tipping prevention edge that prevents the marking member from toppling over the corner of the bottom triangle. In the present invention, “triangular pyramid” and “triangular frustum” do not refer only to the geometrical triangular pyramid and the triangular frustum, respectively. For example, the three side surfaces constituting the marking unit and / or It includes shapes in which side surfaces and oblique sides are appropriately deformed, such as three oblique sides slightly bulging outward.

  As described above, according to the marking member of the present invention, unlike the case where the collar portion is extended outside the bottom portion of the marking portion by a certain length, the collar portion of the marking member is outside the corner of the triangle of the bottom portion. Since the fall prevention edge for preventing the fall is provided, it is possible to reduce the possibility of falling even if the wind blows from the direction perpendicular to the side surface of the sign portion.

  In the marking member of the present invention, preferably, the fall prevention edge is a straight edge extending in a direction along a side of the triangle facing the corner of the triangle. The straight edge is an edge that forms a straight line in plan view.

  With such a configuration, since the fall prevention edge is a straight edge, when the marking member receives a lateral load such as being blown by wind from a direction perpendicular to the side surface of the sign part, the straight edge is lined to the ground. It is possible to make contact and to easily return to the original posture and position. Moreover, since the fall prevention edge is linear, the configuration of the fall prevention edge is simplified, the production of the marking member is simplified, and the production cost can be reduced.

  In the marking member of the present invention, preferably, the flange portion is extended outside the triangle side of the bottom portion from a straight line connecting ends of the adjacent fall prevention edges. It has the bulging part which swelled in the direction, It is characterized by the above-mentioned.

  With such a configuration, since the outer side of the triangle side of the bottom portion is provided with a bulging portion that swells in a direction in which the heel portion extends from a straight line connecting the ends of the adjacent fall prevention edges, The marking member has a longer distance between the triangle side of the bottom and the edge of the collar than when the portion is extended a certain distance outside the bottom of the sign. For this reason, when the sign member receives a lateral load such as being blown by the wind from the direction of the hypotenuse of the sign part that is opposite to the triangle side of the bottom part and the center of the sign member, the hypotenuse side is less likely to float. It is possible to reduce the risk of falling.

  The marking member of the present invention has a fall prevention edge, and is less likely to fall even when subjected to a lateral load such as being blown by wind from a direction perpendicular to the side surface of the marking portion.

  In addition, in the following description, the addition of the alphabet in each code | symbol is abbreviate | omitted except when describing a specific side surface, an angle | corner, and a side. The same applies to the straight edge and the bulging portion described later.

-Constitution-
As shown in FIGS. 1 to 6, the marking member 1 according to the present invention includes a sign portion 2 and a flange portion 3 that extends outside the bottom portion 20 of the sign portion 2 and is installed on the ground. ing.

  As shown in FIGS. 1 and 2, the marking unit 2 includes a lid portion 21 and three side surfaces 22, and the legs of the side surface 22 which is a trapezoid are joined to form the lid portion 21 on the upper side. It is formed in a hollow triangular frustum as shown in FIG. The legs of the joined side surfaces 22 form a hypotenuse 23 of a triangular frustum. The side surface 22 can be easily added with characters, figures, and colors that serve as signs, and as shown in FIGS. 2, 4, 6, and 7, the central portion in the width direction is on the outside. The shape is slightly swollen. Thus, in the present invention, the shape of the marking portion 2 is not limited to a geometrical triangular pyramid or triangular pyramid shape, such as a shape in which the central portion of the side surface 22 in the lateral width direction slightly bulges outward. In addition, a shape obtained by appropriately deforming the side surface 22 and the oblique side 23 is also included.

  As shown in FIG. 1, the lid portion 21 has a triangular frustum shape having a protruding portion 211 whose side surface bulges outward, and has a thickness in the height direction. A fitting hole 212 for fitting an indicator lamp, an adapter, or the like attached to the marking member 1 is formed on the upper surface of the lid portion 21. Thus, since the cover part 21 is provided with the protrusion part 211, when the some marking member 1 is stacked, the display member 1 located in the outer surface of the side surface 22 of the marking member 1 located in a lower stage, and an upper stage. The inner surface of the side surface 22 does not rub against each other. Therefore, it is possible to protect signs such as characters, figures, and colors attached to the outer surface of the side surface 22. Further, the protruding portion 211 can be lifted by placing a hand, and can be used for carrying.

  As shown in FIG. 1, the bottom portion 20 of the marking portion 2 formed in this way is formed into an empty triangle having corners 201a, 201b, and 201c and sides 202a, 202b, and 202c. Therefore, this marking member 1 can be stacked like the conventional one.

  The collar portion 3 includes a straight edge 31 as a tipping prevention edge that prevents the marking member 1 from tipping outside the triangular corner 201 of the bottom portion 20. As shown in FIG. 2, the straight edge 31 forms a straight line in a plan view and extends in a direction along a triangular side 202 facing the triangular corner 201 across the center of the marking member 1. The length of the straight edge 31 is set to a length that can exhibit the fall prevention function in consideration of the height, weight, etc. of the marking member 1.

  As shown in FIG. 2, the flange portion 3 swells in the direction in which the flange portion 3 extends from the straight line L connecting the end portions 311 of the adjacent linear edges 31 to the outside of the triangular side 202 of the bottom portion 20. A bulging portion 32 is provided. The edge 321 of the bulging portion 32 is formed in a gentle arc shape whose central portion is farthest from the side 202. The distance between the side 202 and the edge 321 is set to a length that prevents the marking member 1 from falling over in consideration of the height and weight of the marking member 1.

  As shown in FIG. 5, a plurality of ribs 331 extending in the outer direction are formed on the back surface 33 of the collar portion 3, and three cylindrical leg pieces 332 project along the edge 321 at equal intervals. It is installed. The lower ends of the ribs 331 are aligned with the lower ends of the linear edge 31 and the edge 321. Further, a leg piece 333 made of an elliptical rib extending in parallel with the straight edge 31 is projected from a portion of the back surface 33 corresponding to the straight edge 31. The leg pieces 332 and 333 protrude slightly below the straight edge 31, the edge 321 and the lower end of the rib 331 (on the ground side when installed). Thus, since the rib 331 is provided on the back surface 33 of the collar portion 3, the possibility that the collar portion 3 is bent is reduced, and the leg piece 333 is provided in the vicinity of the linear edge 31, and thus the linear edge 31. The strength of the part is increased.

  The marking member 1 having such a configuration is integrally molded with a synthetic resin such as polyvinyl chloride (PVC), for example, by an injection molding method. For this reason, it can be produced in large quantities at a low cost.

  The marking member 1 is installed and used on a road such as a construction site.

―Action―
Hereinafter, the operation of the marking member 1 will be described by taking as an example the case where the wind is received by the side surface 22b of the marking portion 2.

  As shown in FIG. 7, when the marking member 1 is blown by the wind from the direction perpendicular to the side surface 22 b of the marking portion 2 and lifts under the wind load, the opposite side across the side surface 22 b and the center of the marking member 1 Will be in line contact with the ground. In this way, even if the aircraft is lifted by being blown by the wind, it can resist the wind load by the line contact by the straight edge 31b that does not depend on the conventional point support. When it weakens, it automatically returns to its original posture. Therefore, it is harder to fall than in the case where it is supported on the ground by conventional one-point contact.

  When the marking member 1 is installed on the soil, the leg pieces 332 and 333 are sunk into the ground, and the straight edge 31 of the buttock 3 is in direct contact with the ground. For example, when the marking member 1 is installed on asphalt, the leg The outer edge of the piece 333 also functions as a fall prevention edge that prevents the marking member 1 from falling, like the straight edge 31. If the degree of lifting increases, the outer edge of the leg piece 333 and the linear edge 31 cooperate to function as a fall prevention edge.

  As shown in FIG. 2, the marking member 1 includes a bulging portion 32 that swells in a direction in which the flange portion 3 extends from a straight line L that connects the end portions 311 of the adjacent linear edges 31, so that from the side The marking member 1 has a longer distance between the side 202 and the edge 321 than when the edge separated by a certain distance is formed (when the edge is formed on the straight line L in plan view). . Therefore, when a load from the horizontal direction such as a cross wind is applied from the direction of the oblique side 23 of the sign part 2, the possibility that the oblique side 23 is lifted can be further reduced, and thus the possibility of falling is reduced.

  In addition, the shape of the label | marker part 2 is not restricted to a triangular frustum, A triangular pyramid may be sufficient. Even in this case, since the shape of the collar part 3 which is a characteristic part of the present invention is not affected, the marking member 1 is laterally deformed by wind from the direction perpendicular to the side surface 22 of the sign part 2 Even when a load is applied, the possibility of falling is small.

  Note that the fall prevention edge is not limited to the straight edge 31 described above, and may be an edge gently curved in the inner direction of the flange portion 3. Even in this case, since the marking member 1 is supported by the ground at both ends of the fall prevention edge when the side surface 22 is lifted, the balance of the posture is less likely to be lost compared to the case where the marking member 1 is supported by the ground by one-point contact. The risk of falling is small. In this case, since the fall-preventing edge is curved inward, less material is used, and the cost of the material can be reduced. Moreover, the fall prevention edge is not limited to these configurations, and any fallen edge may be used as long as it can contact the ground at two or more points simultaneously in the extending direction of the edge. That is, what is necessary is just to provide the some point which can contact the ground on the virtual line which carries out a line contact. In this case, since the marking member 1 is supported by the ground at a plurality of points on the fall prevention edge when the side surface 22 is lifted, the balance of the posture is not easily lost as compared to the case where the marking member 1 is supported by the ground by one-point contact. Is less likely to reach

-Modification-
The marking member 1 may be used with a weight 4 attached thereto as shown in FIG. 8 in order to further reduce the possibility of falling.

  The weight 4 is formed in a plate shape that is substantially the same shape and size as the flange 3 in plan view, and a columnar through-hole 41 is formed in the center with a triangle having a slightly larger dimension than the bottom 20 at the bottom. ing. The weight 4 is attached to the marking member 1 through the mark portion 2 through the through hole 41. Since the weight 4 is used through the marking portion 2 in the through hole 41, there is no possibility that the weight 4 falls off the marking member 1 if the marking member 1 is upright. The material of the weight 4 may be the same synthetic resin as the marking member 1 or may be a material having a different specific gravity, particularly a material having a higher specific gravity. In the case of a material having a higher specific gravity, the weight 4 can be made thinner and the material can be saved as compared with the case where the weight is made of the same synthetic resin as the marking member 1.

  In addition, embodiment disclosed this time is an illustration in all the points, Comprising: It does not become the basis of limited interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description of the scope of claims. Moreover, all the changes within the meaning and range equivalent to a claim are included.
