Description

[Technical Field]

[0001] The present invention relates to a cone bed that is attached to a road cone. [Background technology]

[0002] BACKGROUND ART Road cones, which have a base and a display unit erected from the base, have traditionally been placed on roads, event venues, etc. to guide the flow of vehicles and people. Various cone beds and weights have been proposed for use in such road cones.

[0003] For example, Patent Document 1 describes a cone bed that includes a cover member that covers the tapered outer surface of a cone placed on the ground, a plurality of light-emitting elements arranged on the outer surface of the cover member, and a battery that supplies power to the plurality of light-emitting elements.

[0004] For example, Patent Document 2 describes a weight used in a road cone, which is a hollow annular member having an opening that can be opened and closed with a cap, and a filler is filled into the annular member through the opening. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-172987 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-069949 Summary of the Invention [Problem to be solved by the invention]

[0006] However, road cones have a problem in that cracks can develop in the connection between the base and the display unit when they are run over by a vehicle or exposed to sunlight for a long period of time, and as these cracks expand, the road cone can break.

[0007] In the cone bed described in Patent Document 1 and the weight described in Patent Document 2, the connection portion of the load cone is not protected, and therefore there is a risk that the load cone may break for the above-mentioned reason.

[0008] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a cone bed and weight that prevent cracks from occurring at the connection between the base and display part of a road cone. [Means for solving the problem]

[0009] In order to solve the above problem, the present invention is a cone bed that is attached to a road cone that has a base portion, a display portion that stands upright from the base portion, and a connection portion that connects the base portion and the display portion, and that has a covering portion that covers the connection portion.

[0010] According to the present invention, by covering the connection portion of the road cone, the cone is prevented from breaking at the connection portion.

[0011] In a preferred embodiment of the present invention, the cover has an opening into which the display unit is inserted, and an edge of the opening is configured to be able to abut against a side surface of the display unit. This configuration prevents rainwater from entering the connection part and sunlight from irradiating it, thereby reducing deterioration of the connection part and further preventing the cone from breaking at the connection part.

[0012] In a preferred embodiment of the present invention, the covering portion has a hollow truncated cone shape and a top surface, the top surface including an opening into which the display portion is inserted, and the edge of the opening is provided with an abutment portion that surrounds and abuts against the display portion. This configuration makes it possible to use a general-purpose cone bed, such as a road cone with a step on the base.

[0013] In a preferred embodiment of the present invention, the device further comprises a mounting portion extending from the covering portion, the mounting portion being mounted on the base portion. With this configuration, the center of gravity of the road cone is lowered, thereby preventing the road cone from tipping over.

[0014] Another aspect of the present invention is a weight to be attached to a road cone having a base portion, a display portion erected from the base portion, and a connection portion connecting the base portion and the display portion, and having a covering portion that covers the connection portion.

[0015] Another aspect of the present invention is a road cone comprising a corn bed as described above. [Effects of the Invention]

[0016] According to the present invention, it is possible to provide a cone bed and a weight that prevent cracks from occurring in the connection portion that connects the base portion and the display portion of the road cone. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] First Embodiment Hereinafter, a corn bed according to a first embodiment of the present invention will be described with reference to FIGS. The embodiment shown below is an example of the present invention, and the present invention is not limited to the following embodiment. In these drawings, reference numeral 1 denotes a corn bed according to the first embodiment.

[0019] <Configuration> As shown in FIG. 1, the corn bed 1 includes a covering portion 11 that covers the connection portion C3 (see FIG. 9) of the load cone C (see FIG. 9), and a placing portion 12 that extends from the covering portion 11.

[0020] The cone bed 1 is a weight for preventing the road cone C (see FIG. 9) from tipping over. The material of the corn bed 1 has a predetermined elasticity, and synthetic rubber or recycled rubber is preferably used, but there is no particular limitation as long as it is a material with a certain degree of specific gravity. In addition, the materials of the covering part 11 and the mounting part 12 may be different.

[0021] As shown in FIG. 2 or 3, the cover 11 has an opening 111 into which the display unit C2 (see FIG. 9) is inserted.

[0022] The covering portion 11 has a hollow truncated cone shape including a hollow 112 . This lowers the center of gravity of the covering portion 11, making it possible to further prevent the road cone C (see FIG. 9) from tipping over. Furthermore, since there are few corners, the covering portion 11 is prevented from being damaged when subjected to an impact.

[0023] The hollow 112 has a truncated cone shape with a top surface formed therein. More specifically, a part of the top surface defined by the hollow 112 is formed by the inner surface of the top surface 11t of the covering portion 11, which will be described later. This makes it possible to attach the cone bed 1 to the road cone D having a step D4 on the base portion D1 shown in FIG. 9(b).

[0024] The cover 11 also has a top surface 11t that projects inward from the top end, and the top surface 11t includes an opening 111 into which the display unit C2 is inserted.

[0025] The opening 111 communicates with the hollow 112 of the covering portion 11 and is provided so as to overlap with the center of gravity of the covering portion 11 . As a result, the display part C2 (see FIG. 9) is inserted into the center of gravity of the cone bed 1, so that the road cone C (see FIG. 9) can be stably supported.

[0026] The opening 111 has a circular shape in a plan view, and the edge of the opening 111 surrounds the display unit C2 and is provided with an abutment portion 111a that abuts the display unit C2 above the connection portion C3. In other words, the diameter of the opening 111 is set smaller than the diameter of the connection portion C3. As a result, even if a load that deforms the road cone C is applied, the load is distributed not only to the connection portion C3 but also to the portion of the display portion C2 that abuts against the abutment portion 111a, thereby increasing the durability of the road cone C. In particular, if a force is applied in a direction that tilts the axis of the display portion C2, the load on the abutting portion is applied symmetrically in the axial direction with respect to the load applied to the connection portion C3, thereby increasing the durability of the road cone C.

[0027] The mounting portion 12 has a bottom opening 121 that comes into contact with the base portion C1 (see FIG. 9).

[0028] The mounting portion 12 has a hollow rectangular parallelepiped shape that is open on the bottom side, and this hollow 122 communicates with the hollow 112 of the covering portion 11. The diameter of an inscribed circle centered in the axial direction of the hollow 122 is set to be at least larger than the diameter of the connecting portion C3. This ensures that a certain distance is maintained between the connection portion C3 and the mounting portion 12. Furthermore, in addition to the fact that the diameter of the opening 111 is smaller than that of the connection portion C3, a gap is formed around the connection portion C3, which reduces the impact of external forces on the connection portion C3.

[0029] The bottom opening 121 communicates with the hollow 122 of the placement section 12 . This allows the corn bed 1 to be stored stacked on top of other corn beds 1 when not in use.

[0030] <How to use> Hereinafter, a method of using the corn bed 1 will be described with reference to FIGS.

[0031] When attaching the cone bed 1 to the road cone C, the user first inserts the display part C2 into the opening 111 as shown in FIG. At this time, if the base C1 is substantially square in plan view, the display unit C2 may be inserted into the opening 111 in such a way that one side of the placement unit 12 and one side of the base C1 are parallel to each other. In this way, the corners of the placing portion 12 do not protrude outward, preventing the feet of pedestrians from getting caught on the cone bed 1.

[0032] In this way, by attaching the corn bed 1 to the road cone C as shown in FIG. 5, the aforementioned connection part C3 is protected by the corn bed 1.

[0033] When removing the corn bed 1 from the load cone C, the corn bed 1 can be removed from the load cone C by following the reverse procedure of the procedure used to attach the corn bed 1 to the load cone C.

[0034] <Effects> According to this embodiment, the cone bed 1 is provided with a covering portion 11 that covers the connection portion C3, which makes it possible to cover the connection portion C3 of the road cone C and prevents the road cone C from breaking at the connection portion C3.

[0035] Furthermore, the covering portion 11 has an opening 111 into which the display portion C2 is inserted, and the abutment portion 111a of the opening 111 is configured to be able to abut against the side surface of the display portion C2, thereby preventing rainwater from flowing into the connection portion C3 and sunlight from irradiating it, thereby reducing deterioration of the connection portion C3 and further preventing the road cone C from breaking at the connection portion C3.

[0036] Furthermore, the covering portion 11 has a hollow truncated cone shape and has a top surface 11t, and the top surface 11t includes an opening 111 into which the display portion C2 is inserted, and the edge of the opening 111 surrounds the display portion C2 and is provided with an abutting portion 111a that abuts against it, thereby preventing rainwater from flowing into the connection portion C3 and sunlight from irradiating it, reducing deterioration of the connection portion C3 and further preventing the road cone C from breaking at the connection portion C3. In addition, the cone bed 1 can be used for general purposes, such as a road cone D having a step D4 on the base portion D1.

[0037] Furthermore, the road cone C further includes a mounting portion 12 extending from the covering portion 11. By mounting the mounting portion 12 on the base portion C1, the center of gravity of the road cone C is lowered, thereby preventing the road cone C from tipping over.

[0038] In addition, since the cone bed 1 is a weight, the center of gravity of the road cone C is further lowered, which further prevents the road cone C from tipping over.

[0039] Second Embodiment The configuration of the cone bed according to the second embodiment of the present invention will be described below with reference to FIGS. Note that the configurations described in the configuration of the first embodiment but not shown below are the same as those of the first embodiment. Furthermore, the embodiment shown below is an example of the present invention, and the present invention is not limited to the following embodiment. In these figures, the reference numeral 2 denotes a corn bed according to a second embodiment.

[0040] As shown in FIG. 6, the cone bed 2 is a weight including a covering portion 21 that covers the connection portion C3 (see FIG. 9) of the load cone C (see FIG. 9) and a placing portion 22 that extends from the covering portion 21.

[0041] 6 or 7, the covering portion 21 has a hollow conical cylindrical shape including a hollow 222. This facilitates processing during manufacturing and also makes it possible to reduce manufacturing costs.

[0042] The cover 11 also has an opening 211 into which the display C2 is inserted.

[0043] The opening 211 has a circular shape in a plan view, and an edge 211a of the opening 211 is configured so as to be able to abut against the side surface of the display unit C2. <Effects>

[0044] The above-described structure prevents rainwater from flowing into the connection portion C3 and sunlight from irradiating the connection portion C3, thereby reducing deterioration of the connection portion C3 and further preventing the road cone C from breaking at the connection portion C3.

[0045] <Other changes> The shapes and dimensions of the components shown in the above two embodiments are merely examples and can be modified in various ways based on design requirements and the like.

[0046] For example, as shown in Fig. 8, the corn bed 3 does not have to have a mounting portion, which makes it easier to attach the corn bed 3 to the load cone C (see Fig. 9).

[0047] Additionally, the material of the corn bed 3 may be a light alloy such as an aluminum alloy or a magnesium alloy, for example. This makes it easier to carry the corn bed 3. Also, the durability of the corn bed 3 is improved.

[0048] Similarly, in the first and second embodiments, the corn beds 1 and 2 do not have to be weights, and the material of the corn beds 1 and 2 may be a light alloy such as an aluminum alloy or a magnesium alloy.

[0049] In the corn beds 1 and 2, for example, the covering portions 11 and 21 and the placing portions 12 and 22 may be configured to be detachable. In this way, when the covering portion 11, 21 is damaged, it can be replaced with another covering portion 11, 21.

[0050] In addition, in the cone bed 1, the hollow 112 of the covering portion 11 may be formed in a cylindrical shape. In particular, the diameter of the hollow 112 may be formed to be the same as the diameter of the cylindrical step D4. As a result, when the step D4 is attached to the cylindrical road cone D, the cone bed 1 fits into the road cone D, preventing the cone bed 1 from coming off from its designated position.
