  However, in the above-described prior art, the base member fixed to the pedestal mounting portion is weakened due to the use environment or aging deterioration, and the base member cannot be fixed to the pedestal mounting portion, and the base member cannot be fixed when moving. There is a problem that the member falls off. In addition, the type in which a ring-shaped weight is inserted and mounted has a problem that the weight is not fixed and is easily rattled and removed, and the moving operation is troublesome.

  The present invention has been made to solve such a problem, and provides a regulation marker that can prevent the base member from falling off the cone body and can be stably installed on the ground.

  In order to solve the above-described problems, a restriction marker according to the present invention includes a cone body having a substantially conical shape or a truncated cone shape at an upper portion and a pedestal portion having a substantially square shape at a lower portion. A grid-like window frame body on the circumference of the outer peripheral surface of the portion, and a core member formed with a protrusion on the outer periphery of the window frame body, the pedestal portion being embedded with the core member as an axis, the window frame A body and a base member for supporting the protrusion.

  The outer wall of the cone body includes a large and small band-shaped cut surface provided thereon, and a reflection sheet that is fitted into the cut surface and attached.

  Further, the core member is disposed at substantially equal intervals on a rectangular window frame formed at equal intervals on the circumference of the outer peripheral surface of the skirt portion of the base member, and on the outer peripheral edge of the window frame. Consists of protrusions.

  Furthermore, the protrusion of the core member is formed into a T-shape by a radiating member disposed between the window frames and a peripheral protrusion member formed on the outer periphery of the window frame with which the tip of the radiating member abuts. Composed.

  In addition, a band-shaped cut is formed along the bottom surface at the lower end of each side surface of the base member.

  Furthermore, the base member is made of regenerated black polyvinyl chloride.

  Further, the regulation marker of the present invention comprises a cone body having an approximately conical shape or a truncated cone shape in the upper part and a pedestal part having a substantially square shape in the lower part, and the cone body has an outer peripheral surface of the skirt part. A grid-like window frame body on the circumference and a core member formed with a projection on the outer periphery of the window frame body, the pedestal portion embedded with the core member as an aggregate, and the window frame body and the projection body An engaging convex protrusion projecting at a symmetrical position across the cone body on the substantially square upper surface formed by the base member, and the engaging convex protrusion on the back surface An engaging recess for engaging is formed.

  According to the present invention, since the base member is firmly formed by the window frame body and the protrusion of the core member, it is possible to prevent the base member from dropping from the cone body. Further, since the base member holds the core member, it is heavier than the cone body, so that the marker can always be used in a stable state.

  Further, since the reflection sheet attached to the outer wall of the cone body is attached to the cut surface, it does not protrude and is not damaged. Further, since the lower width of the reflection sheet is narrow, the visibility of the reflection sheet and the unique color of the conical body can be emphasized. Further, since the band-shaped cuts are formed on the four sides of the lower end of each side surface of the base member, the wind passes therethrough, so the air resistance is weakened and the cone can be installed stably.

  Furthermore, when the engagement protrusions formed on the surface of the base member and the engagement recesses on the back surface are stacked with the restriction marker of the present invention, both engage with each other in the base body, and rotation is suppressed. , Can be transported and stored stably.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the overall configuration of a restriction marker 10 according to one embodiment of the present invention.

  As shown in FIG. 1, the restriction marker 10 includes a cone body 20 having a substantially conical shape or a substantially truncated cone shape, a square base member 30 formed at the skirt of the cone body 20, and a cone body. And reflection sheets 40 and 41 mounted on the surface (outer wall) of the 20. The height of the restriction marker 10 is about 70 cm.

FIG. 2 is a perspective view showing the cone body 20 of the restriction marker 10.
As shown in FIG. 2, the cone body 20 includes a cone-shaped marker portion 21 on which a reflector and other markers are provided, a core member 22 formed on the lower end skirt portion 21 a of the cone body 20, and a slope. A plurality of large and small cuts 24 and 25 are provided. The cone body 20 is made of a material such as polyvinyl chloride (PVC), and is formed into a hollow substantially conical shape or a truncated cone shape by, for example, an injection molding method. In addition to this material, the cone body 20 may be made of a plastic material such as a synthetic resin. The height of the cone body 20 is about 67 cm.

The marking portion 21 is formed in a hollow substantially conical shape or a substantially truncated cone shape.
The core member 22 is provided on the peripheral edge of the conical or substantially frustoconical skirt 21a of the marker portion 21, and a lattice-like window frame 23 formed at equal intervals in the circumferential direction of the edge surface is substantially regular. Is formed. The core member 22 has a disk shape with a diameter of about 32.8 cm. For example, the lower part has a circular shape concentric with the disk-shaped skirt portion 21 a and is integrally formed with the skirt portion 21 a of the cone body 20. The core member 22 is provided integrally with the outer periphery of the peripheral surface of the skirt portion 21a, and forms a plurality of through-holes that penetrate vertically through the window frame.

  The window frame body 23 is formed in a square shape, for example. When the base member 30 is formed, the window frame 23 can be filled in the base member 30. For example, the window frame 23 has a length of about 2 cm, a radial width of about 0.6 cm, and a height of about 5 cm. It is formed in the size. The shape of the window frame 23 is not limited to a square, but may be other shapes such as a circle or a polygon. Since the plurality of window frames 23 are formed at equal intervals in the circumferential direction of the skirt portion 21a of the cone body 20, a liquid base member material described later flows uniformly into each window frame 23, Since it is filled, the fixed state of the cone body 20 and the base member 30 can be strengthened.

  The core member 22 has protrusions 26 formed vertically on the outer periphery of the window frame 23. As shown in FIG. 2, the protrusion 26 has a radiating member 26a disposed between the window frame members 23 and 23 and a peripheral edge formed on the outer peripheral edge of the window frame member where the tip of the radiating member 26a abuts. The protruding member 26b is formed in a T shape. The protrusions 26 are formed so as to protrude above and below the core member 22. The radiation member 26a and the peripheral protrusion member 26b are formed with a height of about 1.2 cm. The peripheral protrusion member 26b is formed to have a length of about 32 cm.

  The protrusion 26 is embedded in a base member 30 to be described later, so that the contact area with the base member 30 can be further increased. As a result, the fixed state with the base member 30 can be further strengthened.

  The large and small cuts 24 and 25 are provided at predetermined intervals along the circumferential direction on the outer wall of the marker portion 21, and are formed, for example, in a substantially frustoconical strip shape having a predetermined width. A small cut 25 is formed below the large cut 24, and the width of the large cut 24 is preferably about 14.5 cm, and the width of the small cut 25 is preferably about 6.5 cm. The reason why the width of the lower stage is narrowed is to give the original color of the cone body. The large cut 24 is formed approximately 13.5 cm below the top 21 b of the cone body 20, and the small cut 25 is formed approximately 6 cm below the large cut 24.

FIG. 3 is a cross-sectional perspective view showing a cross section of the restriction marker 10.
As shown in FIG. 3, the reflection sheets 40 and 41 are made of a belt-like sheet, and are inserted into the notches 24 and 25, respectively, and are attached to the marker portion 21. The widths of the reflection sheets 40 and 41 are substantially the same as the widths of the cuts 24 and 25, and are set to a width that can enhance the visibility of the restriction marker at night. The thickness of the reflection sheets 40 and 41 is formed substantially the same as the depth of the cuts 24 and 25, and the reflection sheets 40 and 41 are attached to the cuts 24 and 25, respectively.

  In addition, in order to further improve the visibility, for example, a light source that emits light by an LED, a guide bar, or a safety light (marker light) is attached to the top 21b of the sign 21 to make the top 21b shine or blink. You can also.

  Thus, since the reflection sheets 40 and 41 are fitted and inserted into the cuts 24 and 25 without projecting, there is no backlash or movement, and the reflection sheets 40 and 41 are not easily detached from the cone body 20. The reflection sheets 40 and 41 function as reflection sheets that are inserted by being inserted into the cuts.

FIG. 4 is a perspective view showing a fixed state of the cone body 20 and the base member 30 of the restriction marker 10.
As shown in FIG. 4, the base member 30 is made of a material such as polyvinyl chloride (PVC) and is formed in a substantially square shape. The base member 30 is formed by embedding the core member 22 of the cone body 20, and is also filled in cavities formed by the window frame bodies 23 as shown in FIG. The base member 30 is formed by, for example, an injection molding method using insert molding. The base member 30 has a height sufficient for embedding the core member 22, for example, about 4 to 5 cm, and is about 37 cm square.

  In addition, band-shaped cuts 31 and 32 are formed along the bottom surface at the lower end portions of the side surfaces of the base member 30, and leg portions 33 are formed at four corners of the bottom surface of the base member 30. The cuts 31 and 32 are formed so that the four side surfaces of the base member 30 communicate with each other. As described above, since the cuts 31 and 32 communicating with the four side surfaces of the base member 30 are provided, the wind is blown from the cuts 31 and 32 regardless of which direction the wind blows. The applied wind pressure can be reduced. As a result, the regulation marker 10 can be prevented from falling.

The base member 30 is formed integrally with the core member by embedding the core member when formed and filling the window frame.
That is, after the core member 22 of the cone body 20 is inserted into the injection mold, the heated material (polyvinyl chloride) of the liquid base member 30 is injected into the injection mold. By this injection injection, the material of the base member 30 is embedded in the core member 22 and filled in the window frame 23, and then the material is cooled and solidified to form a substantially square base member 30. Thereby, the base member 30 is fixed to the core member 22 and formed integrally with the cone body 20.

  The base member 30 can be a recycled product of black polyvinyl chloride that has been subjected to a regeneration process, thereby making it possible to effectively use resources and reduce manufacturing costs. The base member 30 may be molded by using a molding method such as pressure molding, for example.

  The base member 30 is formed with a weight of about 1.8 kg or more, and functions as a weight for stably installing the restriction marker 10 at the site. Therefore, the center of gravity of the regulation marker 10 is lowered and stable at the site. Can be installed. In this way, since the specific gravity of the base is heavy and stable, even if it is dropped on a road surface from a high place (about 1.5 m) such as a loading platform of a construction vehicle at the construction site, it falls or rolls over. It is difficult. The total weight of the restriction marker 10 is preferably about 3.5 kg or more. Further, the shape of the base member 30 is not limited to the substantially square shape described above, and may be, for example, a substantially circular shape or a polygonal shape.

  In this restriction marker 10, since the core member 22 and the base member 30 of the cone body 20 are fixed by an injection molding method using insert molding, the cone body 20 and the base member 30 are integrally formed.

  Thus, according to the regulation marker of this embodiment, the cone body is formed so as to be embedded in the base member, and the cone body and the base member can be integrally fixed. As a result, it is possible to prevent the base member from being detached from the cone body and falling off.

  Moreover, since the reflective sign is fitted into the cut of the cone main body and attached to the regulation marker of this embodiment, the reflective sheet engages with the cone main body and is difficult to fall off from the cone main body. As a result, the visibility of the restriction marker can be further increased.

  In addition, since the restriction marker of this embodiment forms a plurality of window frames and projections at equal intervals in the circumferential direction of the hem of the cone body, the liquid base member material is in each window frame. It becomes easy to flow in and be filled easily, and the fixed state between the cone body and the base member can be further strengthened.

  Further, the regulation marker of this embodiment is provided with a protrusion on the core member of the cone body, and the protrusion is also embedded in the base member, so that the contact area between the cone body and the base member can be increased. As a result, the fixed state between the cone body and the base member can be further strengthened.

  FIG. 5 is a perspective view showing another embodiment of the cone body 20. The example which does not have the through-hole of 20 top sides of a cone main body is shown. Others are the same as the above-mentioned embodiment, and exhibit the same effect.

FIG. 6 is a perspective view showing another embodiment of the base member 30, and FIG. 7 is a bottom view showing the bottom surface of the base member 30 shown in FIG. In this embodiment, circular engagement protrusions 34 are formed on the surface of the substantially square base body 30 at positions facing the cone body 20 as an axis. An engagement recess 50 that engages with the engagement protrusion 34 is formed on the back surface of the base member 30. As shown in FIG. 7, the back surface of the base member 30 is substantially symmetrical with the legs 35, 36 of the legs 33, 33, 33, 33 formed at the four corners of the base body 30 in the same plane. Is formed. A circular engagement recess 50 that engages with the engagement protrusion 34 is formed at a position surrounded by the leg 33 and the legs 35 and 36.
The engaging protrusions 34 of the base body 30 are engaged with and fixed to the engaging recesses 50 on the back surface of the other base body 30. The four engaging protrusions 34 are formed so as to intersect the base body at a position facing the axis, but may be two facing protrusions.

  The engaging protrusions 34 and the engaging recesses 50 of the base member 30 are integrally formed by, for example, an injection molding method using insert molding. As a result, during actual use, the engaging protrusions 34 and the engaging recesses 50 are regularly stacked when the restriction markers according to the present invention are stacked from above.

  FIG. 8 is a perspective view showing still another embodiment of the base member 30. In this embodiment, instead of the engaging protrusions 34 shown in FIG. 6, crescent-shaped locking protrusions 51 and 52 are formed at an angle orthogonal to each other and the cone body 20 is opposed to the shaft. The crescent-shaped locking projections 51 and 52 engage with the outside of the wall surface formed by the legs 35 and 36 of the base body 30. Four crescent-shaped locking projections 51 and 52 are formed in such a way that the base body 30 intersects with the position facing the axis, but two crescent-shaped locking protrusions 51 and 52 may intersect each other. In the regulation marker of this embodiment, it is the same as the above-mentioned embodiment, and exhibits the same operation effect.
