Description

  The present invention relates to a marking cone used for marking a required area on a road or a passage.

  For example, as a marking cone used for marking an area where people and vehicles can pass on a construction site, a road, or the like, for example, a cone shown in Patent Document 1 has been proposed. The cone of Patent Document 1 is configured so that the cone itself can be folded flat by attaching a bottom plate that can be folded at the center to a lower opening of the cone body formed in at least a quadrangular pyramid shape.

However, since the cone is provided with a bottom plate in the lower part of the cone body, the cone cannot be stacked and accumulated in a square pyramid state. For this reason, after use, it is necessary to fold flat and accumulate, and this work is troublesome and requires a lot of accumulation space.

In addition, in order to assemble the cone of Patent Document 1 into a quadrangular pyramid shape, it is necessary to fold the cone body into a quadrangular pyramid shape, fix the bottom plate in a flat shape to the lower part of the cone body, and then fit a weight member to the lower part of the cone There is a problem that the assembly work takes time and labor. In particular, at the work site, it is necessary to arrange the cones in a short time, but it takes time to assemble the cones, and the whole cone arrangement operation cannot be performed efficiently. In addition, since the weight member is separate from the cone body, when the cone is folded flat, the cone body must be folded after removing the weight member from the cone, and the workability is also poor. .
Japanese Patent Laid-Open No. 10-1918

The problem to be solved is that it is necessary to remove the weight member from the cone in order to fold it flatly after use and to collect it. In order to assemble the cone, it is necessary to fold the cone body into a quadrangular pyramid shape, fix the bottom plate in a flat shape, and attach a weight member to the lower part of the cone body. is there. Furthermore, when the cone is folded flat, the cone body must be folded after removing the weight member from the cone body, which is inferior in workability.

The present invention is provided with a cone body formed by bending a plate material into an even-numbered polygonal pyramid shape of at least a hexagon, an opening having a size and a shape into which a lower portion of the cone body can be inserted, and a central portion of the opening. It consists of a weight plate member that can be folded in two and the lower part of the cone body is fixed to the peripheral edge of the opposing opening. The weight plate member can be folded in two and overlapped so that the cone body can be folded flat and weighted. By developing the plate member in a flat shape, the lower part can be inserted into the opening of the weight member while forming the cone main body into at least a hexagonal pyramid shape.

In the present invention, it is not necessary to remove the weight member from the cone in order to fold it flatly after use and to collect it, and the work can be performed efficiently. Further, in order to assemble the cone, it is possible to fold the cone body into a desired shape by flattening the overlapped weight members, and to perform the assembling work efficiently.

The present invention makes it possible to fold the cone body in a flat shape by folding the weight plate member in two and superimposing it, and at the same time forming the cone body at least in a hexagonal pyramid shape by developing the weight plate member in a flat shape. It is the best mode that can be inserted into the opening of the weight member.

The present invention will be described below with reference to the drawings showing embodiments.
1 to 4, the marking cone 1 includes a cone body 3 and a weight bottom plate 5 attached to a lower portion of the cone body 3. The cone body 3 is a paper sheet that is heat-pressed after a single-layer paper material coated with a waterproof film made of a synthetic resin film on at least the surface or a plurality of paper materials coated with a waterproof film on at least the surface are overlaid. Either a laminated paper material obtained by melting a waterproof film between materials and fusing each other, or a synthetic resin material formed into at least a hexagonal pyramid shape. When the cone body 3 is made of a paper material, the paper material cut into a fan-shaped developed shape shown in FIG. 3 is bent into a hexagonal pyramid shape.

In the case where the plate material is a paper material, recycled paper may be used. Further, when the plate material is made of synthetic resin, the synthetic resin plate may be bent and formed into a hexagonal pyramid shape in the same manner as the paper material.

  The plate member 7 constituting the cone body 3 is a sector shape in which the equilateral sides of the six isosceles triangles 7a to 7f having acute angles are shared with each other, and isosceles of the isosceles triangles 7a and 7f located on both sides of the sector shape. The joint pieces 7g are integrally provided, and for example, the fixed pieces 7h are integrally formed at the lower ends of the isosceles triangles 7b and 7e.

  And after forming along hexagonal pyramid shape by bending along the ruled line 7j formed in the isosceles of the isosceles triangles 7a-7f which adjoin each other, the isosceles triangle which is located in the edge part side mutually overlapping joining piece 7g The hexagonal pyramid-shaped cone body 3 is fixed by being superposed on the back surface of the equal side of 7a. As a means for fixing the joining pieces 7g to the opposite sides of the isosceles triangles 7a facing each other, a double-sided tape is attached to the entire surface of at least one joining piece 7g, and when bending into a hexagonal pyramid shape, The bonding pieces 7g are adhered and fixed to each other with a double-sided tape from which the release paper has been peeled off, or fixed with rivets or staples that are inserted through the same sides of the overlapping bonding pieces 7g and the isosceles triangle 7a. The bonded piece 7g temporarily fixed with the double-sided tape may be fixed to the opposite isosceles triangle 7a with the rivets or staples.

  The cone body 3 has a hexagonal pyramid shape as shown in the figure, but may have an even-numbered polygonal pyramid shape that is larger than the hexagonal pyramid shape. Further, a pick piece 7k is attached to the top of the cone body 3 for picking up when the marker cone 1 is lifted.

  The weight bottom plate 5 fixed to the lower portion of the cone body 3 is, for example, the same paper material or resin corrugated cardboard as the cone body 3, and has a hexagonal shape with a size that fits into the lower portion of the cone body 3 at the center. A plate 9 in which both side plates 9c and 9d of the flat plate 9b in which the opening 9a is formed is folded and overlapped with the lower surface of the flat plate 9b, and the overlapped flat plate 9b and both side plates 9c and 9d are overlapped. For example, a weight 11 such as an iron plate is sandwiched between them.

  In addition, notches 9e and 9f having a size and a shape corresponding to the half of the opening 9a are formed at the ends of the side plates 9c and 9d.

  The weight bottom plate 5 is formed by fixing fixed pieces 7h and 7i, which are integrally formed below the isosceles triangles 7b and 7e in the cone body 3 and bent so as to extend in the horizontal direction, to the flat plate 9b and the respective side plates 9c. -Adhere in a state of being sandwiched between 9d, or fix with rivets or staples that pass through them.

  A ruled line 9g that allows the flat plate 9b to be bent is formed at the center of the flat plate 9b so as to coincide with the ends of both side portions 9c and 9d that are superimposed on the lower surface. Reference numeral 9h in the figure denotes a spacer plate that is fixed between the flat plate 9b and the side plates 9c and 9d and that forms a space for mounting the weight 11 therebetween.

Next, the assembly and folding operation of the marker cone 1 will be described.
When not in use, as shown in FIG. 5, the cone main body 3 whose lower part protrudes from the opening 9a and the notches 9e and 9f by folding the weight bottom plate 5 along the ruled line 9g and overlapping it, for example, The opposing isosceles triangles 7a, 7b, and 7c are bent so that the isosceles triangles 7d, 7e, and 7f overlap each other, and are folded into a flat shape. Then, the stacking space can be reduced by stacking and stacking the marker cones 1 folded in a flat shape, for example.

  Thus, when not in use, the cone body 3 and the weight bottom plate 5 can be folded together in a flat state, and the labor of removing the weight from the cone body can be saved as in the prior art. Further, it is possible to prevent the cone body 3 and the weight bottom plate 5 from falling apart during storage.

  On the other hand, as shown in FIG. 6, in order to assemble the marker cone 1 folded into a flat shape as described above into a hexagonal pyramid shape, it is folded in a state where the upper part of the folded cone body 3 is held and lifted. When the weight bottom plate 5 is pressed against the ground or floor surface of the installation place and expanded in a flat shape, the isosceles triangles 7a, 7b, 7c and two in the cone body 3 folded flatly with the expansion of the weight bottom plate 5 are obtained. The equilateral triangles 7d, 7e, and 7f are formed in a hexagonal pyramid shape while being spaced apart from each other.

When the cone body 3 is assembled into a hexagonal pyramid shape and the weight bottom plate 5 is developed in a flat shape, the lower portion of the cone body 3 is opened to the opening 9a and the notch 9e of the weight bottom plate 5 as shown in FIG. The cone body 3 can be kept in a hexagonal pyramid shape by being inserted into the opening formed by 9f.

  As described above, the sign cone 1 of the present embodiment can be assembled by a simple operation in which the weight bottom plate 5 in a state where the folded sign cone 1 is lifted is pressed against the ground or floor surface of the installation place to be developed flat. it can.

  Since the center of gravity of the marker cone 1 assembled in a hexagonal pyramid shape is located on the lower side due to the weight 11 attached to the weight bottom plate 5, it easily falls down due to wind or wind pressure generated by the passage of the vehicle. The desired area can be marked with no signs.

In the case of the marker cone 1 assembled as described above, the other marker cones 1 are stacked in order from the upper side of the marker cone 1 positioned below in the assembled state, and multi-stage integration is performed in the assembled state. can do.

  In the first embodiment, the weight bottom plate 5 has a structure in which a weight 11 such as a heavy iron plate is sandwiched between the flat plate 9b of the plate member 9 and the side plates 9c and 9d. The sign cone to which the weight bottom plate 5 is attached. When discarding 1, it is necessary to remove the weight 11 from the plate material 9, which takes time.

  The present embodiment solves the above-mentioned problems. As shown in FIG. 8, the weight bottom plate 21 of the marking cone 1 is made of, for example, waste synthetic resin material, which is industrial waste, A high specific gravity material such as blast furnace oxidation slag and fly ash adjusted to the particle size is added and molded with a composite waste resin material. That is, the weight bottom plate 21 is formed with an opening portion 21a having a shape and size that allows the lower portion of the cone body 3 to be inserted into the center portion, and at the lower surface side of the center portion passing through the opening portion 21a. For example, a groove 21b having a V-shaped or U-shaped cross section that can be folded in half is formed to form a fragile portion.

  The weight bottom plate 21 at the periphery of the opening 21a to which the fixing pieces 7h and 7i are respectively fixed is formed with recesses 21c and 21d, and the recesses 21c and 21d are formed in the fixing pieces 7h and 7i, respectively. Shafts 21e and 21f are formed through the holes. Then, as shown in FIG. 9, the end portions of the shafts 21 e and 21 f that pass through the holes of the fixing pieces 7 h and 7 i are crimped or thermally deformed to fix the weight bottom plate 21 to the lower portion of the cone body 3.

In the above description, the resin material and the high specific gravity material constituting the composite waste resin material are each industrial waste, but it is needless to say that a virgin material may be used. Further, since the weight bottom plate 21 is folded in half at the above-described groove portion 21b when not in use, polypropylene having excellent hinge characteristics is suitable as the synthetic resin material, but is not limited thereto.

  Since the weight bottom plate 21 itself is a synthetic resin material, when the marker cone 1 is disposed of, the weight bottom plate 21 may be removed from the cone body 3 and disposed separately. Time and effort at the time of disposal can be reduced.

  In the present embodiment, as shown in FIG. 10, the weight bottom plate 31 is formed with an opening 33a having a size and shape into which the lower part of the cone body 3 can be fitted at the center, and a central lower surface passing through the opening 33a. The resin plate 33 made of, for example, polypropylene resin corrugated board having a hinge characteristic, and the bottom surface of the resin plate 33 with the cut portion 33b as the center are fixed to the symmetrical portion. Similarly to the weight bottom plate 21 of Example 2, for example, a composite waste resin material or an iron plate obtained by adding a high specific gravity material such as blast furnace oxidation slag or fly ash which is also an industrial waste to a waste synthetic resin material which is an industrial waste. And a pair of weights 35 each having a notch 35a having a shape corresponding to a part of the opening 33a on opposite sides.

Recesses 35b corresponding to the respective fixing pieces 7h and 7i are formed in the weights 35 around the notches 35a, and holes formed in the respective fixing pieces 7h and 7i are formed in the respective recesses 35b. A shaft 35c through which is inserted is formed.

As shown in FIG. 11, the weight 35 is fixed to the lower portion of the cone body 3 by crimping or thermally deforming the end of the shaft 35c through which the fixing pieces 7h and 7i are inserted.

An opening 53c having a possible shape and size is formed, and a groove 53d is formed in the intermediate portion so that the opening 53c can be folded in half through the opening 53c. A fixed piece 53a is foldably provided on the flat plate 53b corresponding to the symmetrical position of the periphery of the opening 53c.

  Further, on both sides of the flat plate 53b, there are folded pieces 53e that are folded back to the lower surfaces on both sides of the flat plate 53b with a required interval, and folded pieces 53f that are folded on the lower inner surface of the cone body 3 on both sides of the folded pieces 53e. Each ruled line is formed so that it can be bent.

  After the weights 55 are attached to both sides of the flat plate 53b, the weight plate material 51 is folded so that the folded piece 53e is folded and the weight 55 is sandwiched between the folded piece 53f and the opening 53c. Also, the fixed piece 53a is folded back so as to stand up relative to the upright folded piece 53f.

  The weight plate material 51 formed as described above is bonded to the lower portion of the cone body 3 while being inserted between the fixing piece 53a located on the outer surface side and the folding piece 53f located on the inner surface side, or inserted through these. Are fixed and integrated by fixing members 57 such as rivets and staples.

  Reference numeral 53g in the figure is a spacer plate provided between the flat plate 53b and the folded piece 53e.
