Description

[Technical Field]

[0001] The present invention relates to a cone bar that is connected to a cone to define a designated area. [Background technology]

[0002] Conventionally, in order to demarcate designated areas at construction sites, event venues, etc., it has been common practice to place cones connected by cone bars to restrict people from entering and exiting the designated areas. Many inventions relating to this type of field have been disclosed, such as JP 2021-127656 A (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-127656 Summary of the Invention [Problem to be solved by the invention]

[0004] As disclosed in Patent Document 1, cylindrical cone bars are often used. Although this poses few problems when they are installed in designated areas, cylindrical cone bars can be unstable and difficult to handle, for example, when storing or transporting multiple cone bars together.

[0005] In view of the above situation, there is a need for a cone bar that is easy to handle when not installed in a designated area, such as during storage or transportation. [Means for solving the problem]

[0006] A cone bar that is connected to the cone and defines a designated area, An elongated main body portion; a cone connection portion provided at least at one of one end and the other end in the longitudinal direction of the main body portion, At least one of the main body portion and the cone connection portion is provided with a pair of symmetrical flat surface portions that face in opposite directions and are formed in a flat shape.

[0007] According to this configuration, since the target plane portion is formed in a flat shape, placing the target plane portion on a support surface such as a floor or stand makes it easy to stabilize the entire cone bar. Furthermore, since the pair of target plane portions are arranged facing opposite each other, when multiple cone bars are grouped together, the target plane portions of different cone bars can be in surface contact with each other, making it easy to ensure the stability of the group. For example, it is also easy to stack multiple cone bars vertically. Thus, according to this configuration, the cone bars are easy to handle when not installed in the designated area, such as during storage or transportation.

[0008] Further features and advantages of the techniques according to the present disclosure will become more apparent from the following description of exemplary and non-limiting embodiments, which proceeds with reference to the drawings. [Brief explanation of the drawings]

[0009] [Figure 1] Shows cone bars connected to cones installed in designated areas. [Figure 2] (a) shows a front view of the cone bar, and (b) shows a plan view of the cone bar. [Figure 3] 3 shows a cross-sectional view taken along line III-III in FIG. 2. [Figure 4] 4(a) is a cross-sectional view taken along line IV-IV in FIG. 2, and FIG. 4(b) shows how the upper and lower engaging portions of different cone bars are engaged with each other. [Figure 5] This shows the state of transporting multiple cone bars. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the cone bar will be described with reference to the drawings.

[0011] As shown in FIG. 1, the cone bar 100 is connected to the cone 9 to define a designated area A.

[0012] The designated area A is an artificially set area, and may be set at a construction site or an event venue, for example. The cone bar 100 is used as a boundary to restrict movement of people between the designated area A and external areas.

[0013] The cone 9 is a so-called color cone (registered trademark), and is usually cone-shaped. There are various types of cones 9 depending on the application. Examples of the cone 9 include a cut cone with a cut tip, a color cone made of synthetic rubber, a color cone with a reflective material used at construction sites at night, and a large jumbo cone. The cone bar 100 according to the present disclosure can be applied to these various types of cones 9.

[0014] The designated area A can be partitioned by arranging a plurality of cones 9 as described above along the boundary of the designated area A and connecting adjacent cones 9 with a cone bar 100.

[0015] FIG. 2( a ) shows a front view of the cone bar 100 , and FIG. 2( b ) shows a plan view of the cone bar 100 .

[0016] 2, the cone bar 100 includes an elongated main body 1 and a cone connecting portion 2 provided on at least one of one end and the other end in the longitudinal direction of the main body 1. In the illustrated example, the cone connecting portion 2 is provided on both ends of the main body 1 in the longitudinal direction.

[0017] The cone connecting part 2 has an insertion part 24 into which the tip of the cone 9 is inserted. The insertion part 24 of the cone connecting part 2 is dropped from above onto the tip of the cone 9 placed on the ground 70, thereby inserting the tip of the cone 9 into the insertion part 24 (see FIG. 1). By performing the same procedure on the other side of the cone bar 100, adjacent cones 9 can be connected by the cone bar 100. In the illustrated example, a ring-shaped insertion part 24 is shown, but the insertion part 24 is not limited to this and can also be shaped like a C-shaped ring with a portion of the ring that is discontinuous.

[0018] The main body 1 defines the boundary of the designated area A. Therefore, to make it easier to see that it is the boundary of the designated area A (to make it more visible), the surface of the main body 1 may be painted alternately in black and yellow, or lights or reflectors may be provided.

[0019] Here, in the cone bar 100 according to the present disclosure, at least one of the main body portion 1 and the cone connection portion 2 is provided with a pair of target flat surface portions S that face in opposite directions and are formed in a flat shape.

[0020] Because the target flat surface portion S is formed in a flat shape, when the cone bar 100 is not installed in the designated area A (hereinafter simply referred to as "when not installed"), it is easy to stabilize the entire cone bar 100 by placing the target flat surface portion S on the floor, a stand, etc. Also, because the pair of target flat surfaces S are arranged facing opposite each other, when multiple cone bars 100 are grouped together when not installed, the target flat surfaces S of different cone bars 100 can be in surface contact with each other, making it easy to ensure the stability of the group.

[0021] The main body 1 and the cone connecting portion 2 are arranged on the same axis. The diameter of the main body 1 is smaller than the diameter of the cone connecting portion 2. Therefore, for example, when the cone bar 100 is placed on the ground 70, the cone connecting portion 2 comes into contact with the ground 70. Therefore, in this embodiment, at least the cone connecting portion 2 is provided with a pair of target flat portions S. In this way, by providing the cone connecting portion 2, which is likely to come into contact with other objects (for example, the ground 70), with a pair of target flat portions S, it is easier to stabilize contact with other objects.

[0022] In this embodiment, a pair of target flat surfaces S is provided in each of the main body 1 and the cone connecting portion 2. That is, as described above, a pair of target flat surfaces 20 (hereinafter referred to as "connection-side target flat surfaces 20") is provided in the cone connecting portion 2, and a pair of target flat surfaces 10 (hereinafter referred to as "main body-side target flat surfaces 10") is also provided in the main body 1.

[0023] As shown in Fig. 3, in this embodiment, the cross section of the main body 1 in a plane perpendicular to the longitudinal direction is formed into a quadrangle. Of the four sides of the quadrangle, two opposing sides are main body-side symmetrical plane portions 10. The other two sides are asymmetrical plane portions 13. In this example, since the cross section of the main body 1 is quadrangle, the other two sides, that is, the pair of asymmetrical plane portions 13, are also formed into a plane.

[0024] FIG. 4(a) is a cross-sectional view taken along line IV-IV in FIG.

[0025] As shown in Figure 4(a), of the pair of connection side target plane portions 20 provided on the cone connection portion 2, the connection side target plane portion 20 facing upward is referred to as the upper target plane portion 21, and the connection side target plane portion 20 facing downward is referred to as the lower target plane portion 22.

[0026] The upper target plane portion 21 is provided with an upper engagement portion 210 configured to engage with the lower target plane portion 22 of another cone bar 100. The lower target plane portion 22 is provided with a lower engagement portion 220 configured to engage with the upper target plane portion 21 of another cone bar 100.

[0027] In this embodiment, the upper engagement portion 210 has a convex portion 211 that protrudes outward (upward) from the upper target plane portion 21 and a concave portion 212 that is recessed inward (downward) from the upper target plane portion 21. The lower engagement portion 220 has a convex portion 221 that protrudes outward (downward) from the lower target plane portion 22 and a concave portion 222 that is recessed inward (upward) from the lower target plane portion 22.

[0028] The convex portions 221 of the lower engagement portion 220 are arranged at positions overlapping the concave portions 212 of the upper engagement portion 210 when viewed in the vertical direction. The concave portions 222 of the lower engagement portion 220 are arranged at positions overlapping the convex portions 211 of the upper engagement portion 210 when viewed in the vertical direction. In other words, the upper engagement portion 210 and the lower engagement portion 220 have a staggered structure in which the positions of the convex portions (211, 221) and the concave portions (212, 222) are interchangeable.

[0029] With this configuration, when different cone bars 100 are stacked vertically as shown in FIG. 4(b), at a first position P1 in the figure, the convex portion 211 of the upper engagement portion 210 of the cone bar 100 arranged below and the concave portion 222 of the lower engagement portion 220 of the cone bar 100 arranged above engage with each other. At the same time, at a second position P2 different from the first position P1, the concave portion 212 of the upper engagement portion 210 of the cone bar 100 arranged below and the convex portion 221 of the lower engagement portion 220 of the cone bar 100 arranged above engage with each other. As such, in this embodiment, the upper engagement portion 210 and the lower engagement portion 220 have complementary shapes. This configuration increases the degree of freedom in the engagement mode between the upper engagement portion 210 and the lower engagement portion 220, making it possible to stack different cone bars 100 regardless of their orientation.

[0030] In this embodiment, the protrusions (211, 221) are formed in a rectangular parallelepiped shape, and the recesses (212, 222) that fit therewith are formed to have sizes that match the corresponding protrusions (211, 221).

[0031] In this embodiment, the recesses (212, 222) are formed to have the same size as the corresponding protrusions (211, 221), thereby enabling the two to be firmly fitted together.

[0032] On the other hand, the recesses (212, 222) may be formed to have a larger size than the corresponding protrusions (211, 221). This allows for a more ample fit between the two, facilitating attachment and detachment of different cone bars 100, thereby improving workability. In this case, it is preferable to form the protrusion length of the protrusions (211, 221) longer than usual. This improves attachment and detachment workability while preventing the protrusions (211, 221) from accidentally coming off when they are fitted into the recesses (212, 222).

[0033] In this embodiment, the recesses (212, 222) are through-holes that penetrate a part (connection-side target flat surface portion 20) of the cone connecting part 2. However, the present invention is not limited to this configuration. The recesses (212, 222) may be, for example, blind holes (simple depressions) as long as they are configured so that the corresponding protrusions (211, 221) fit therein.

[0034] The cone bar 100 described above is easy to handle when not installed in the designated area A. For example, even if the cone bar 100 is placed on the ground 70 and the cone connection part 2, rather than the main body part 1, comes into contact with the ground 70, the posture of the cone bar 100 can be stabilized by bringing the connection side target flat part 20 provided on the cone connection part 2 into surface contact with the ground 70.

[0035] When stacking different cone bars 100 together in the vertical direction, the stability of the group of multiple cone bars 100 can be easily ensured by bringing the connecting side target plane portions 20 adjacent in the vertical direction into surface contact with each other and engaging the upper engagement portion 210 with the lower engagement portion 220.

[0036] For example, as shown in Figure 5, when transporting one or more cone bars 100 using a dolly 8, the main body side target flat surface 10 of the cone bar 100 can be brought into surface contact with the mounting surface 80 of the dolly 8. In particular, when transporting a cylindrical cone bar using a dolly as in the past, the cylindrical curved surface of the cone bar comes into contact with the mounting surface of the dolly, making it difficult to ensure stability. However, with the cone bar 100 according to the present disclosure, it is possible to stabilize the position of the cone bar 100 on the dolly 8 even when transporting using the dolly 8.

[0037] Other Embodiments Next, other embodiments will be described.

[0038] (1) In the above embodiment, an example in which the cross section of the main body 1 is rectangular has been described. However, the present invention is not limited to this example. As long as the main body 1 is provided with at least one pair of target plane portions S, the shape of the other portion (non-target plane portion 13) can be designed as desired. For example, the non-target plane portion 13 may have a shape with one or more corners, or may be formed as a curved surface. Alternatively, at least a portion of the non-target plane portion 13 may have a ridge-like uneven surface along the vertical direction (up and down direction) that matches the shape of a person's hand.

[0039] (2) In the above embodiment, an example has been described in which the protrusions (211, 221) of the upper engagement portion 210 and the lower engagement portion 220 are formed in a rectangular parallelepiped shape. However, the present invention is not limited to such an example, and the protrusions (211, 221) may be, for example, partially or entirely rounded or wedge-shaped, as long as they at least protrude from the target flat surface portion S.

[0040] (3) In the above embodiment, an example has been described in which the upper engagement portion 210 and the lower engagement portion 220 each have only one convex portion (211, 221). However, the present invention is not limited to this example, and each of the upper engagement portion 210 and the lower engagement portion 220 may have multiple convex portions (211, 221). In this case, the same number of concave portions (212, 222) as the convex portions (211, 221) are provided corresponding to the convex portions (211, 221).

[0041] (4) In the above embodiment, an example has been described in which the upper engagement portion 210 and the lower engagement portion 220 each include a convex portion (211, 221) and a concave portion (212, 222) that fit together, and are engaged by fitting these together. However, without being limited to this example, the upper engagement portion 210 and the lower engagement portion 220 each may include a magnetic body and be configured to engage with each other by magnetic force.

[0042] (5) The configurations disclosed in the above-described embodiments can be applied in combination with configurations disclosed in other embodiments, as long as no contradictions arise. Regarding other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications can be made as appropriate within the scope of the present disclosure.

[0043] [Summary of this embodiment] The summary of this embodiment will be described below.

[0044] A cone bar that is connected to the cone and defines a designated area, An elongated main body portion; a cone connection portion provided at least at one of one end and the other end in the longitudinal direction of the main body portion, At least one of the main body portion and the cone connection portion is provided with a pair of symmetrical flat surface portions that face in opposite directions and are formed in a flat shape.

[0045] According to this configuration, since the target plane portion is formed in a flat shape, placing the target plane portion on a support surface such as a floor or stand makes it easy to stabilize the entire cone bar. Furthermore, since the pair of target plane portions are arranged facing opposite each other, when multiple cone bars are grouped together, the target plane portions of different cone bars can be in surface contact with each other, making it easy to ensure the stability of the group. For example, it is also easy to stack multiple cone bars vertically. Thus, according to this configuration, the cone bars are easy to handle when not installed in the designated area, such as during storage or transportation.

[0046] Preferably, a pair of the target flat surface portions is provided at least on the cone connection portion.

[0047] When the diameter of the main body is smaller than the diameter of the cone connecting portion, the cone connecting portion is more likely to come into contact with the floor surface. Also, when multiple cone bars are grouped together, the cone connecting portions of different cone bars are more likely to come into contact with each other. With this configuration, a pair of flat target portions is provided on the cone connecting portion, which often comes into contact with other objects (such as the floor surface or other cone bars), making it easier to stabilize contact with other objects.

[0048] The target plane portion facing upward of the pair of target plane portions provided on the cone connection portion is defined as an upper target plane portion, and the target plane portion facing downward is defined as a lower target plane portion, The upper target plane portion is provided with an upper engagement portion configured to engage with the lower target plane portion of another cone bar, Preferably, the lower target plane portion is provided with a lower engagement portion configured to engage with the upper target plane portion of another of the cone bars.

[0049] According to this configuration, when a plurality of cone bars are bundled together, the upper engaging portions and lower engaging portions of different cone bars are engaged with each other, which makes it easier to ensure stability in the bundle.

[0050] Preferably, the upper engaging portion and the lower engaging portion have complementary shapes.

[0051] According to this configuration, the degree of freedom in the engagement mode between the upper engagement portion and the lower engagement portion is increased, and for example, different cone bars can be grouped together without regard to their orientation. [Industrial Applicability]

[0052] The technology according to the present disclosure can be used for cone bars that are connected to cones to define designated areas. [Explanation of symbols]
