Description

[Technical Field]

[0001] The present invention relates to a cone bar connected to cones to demarcate a designated area. [Background Art]

[0002] Conventionally, in order to demarcate a designated area at construction sites, event venues, etc., it has been common practice to connect cones to each other with cone bars and arrange them to regulate the entry and exit of people into and out of the designated area. Many inventions related to this type of field have also been disclosed, for example, as disclosed in Japanese Unexamined Patent Application Publication No. 2021-127656 (Patent Document 1). [Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Japanese Unexamined Patent Application 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. This rarely causes a problem when installed in a designated area, but when a plurality of cone bars are stored or transported collectively, for example, the cylindrical shape of the cone bars results in poor stability and difficult handling, which is a problem.

[0005] In view of the above circumstances, 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 connected to cones to demarcate a designated area, an elongated main body; and a cone connecting portion provided on at least one of one end portion and the other end portion 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 planar portions that face opposite each other and are formed in a planar shape.

[0007] With this configuration, since the target plane is formed in a flat shape, the entire cone bar can be easily stabilized by placing the target plane on a surface such as a floor or table. Furthermore, because the pair of target planes are provided facing opposite directions, when multiple cone bars are bundled together, the target planes of different cone bars can be brought into surface contact, making it easier to ensure the stability of the bundle. For example, it becomes easy to stack multiple cone bars in the vertical direction. Thus, with this configuration, handling of the cone bar becomes easier when it is not installed in a designated area, such as during storage or transportation.

[0008] Further features and advantages of the technology relating to this disclosure will become clearer from the following description of exemplary and non-limiting embodiments, with reference to the drawings. [Brief explanation of the drawing]

[0009] [Figure 1] This indicates that a cone bar connected to a cone has been installed in the designated area. [Figure 2] (a) shows a front view of the cone bar, and (b) shows a top view of the cone bar. [Figure 3] Figure 2 shows a cross-sectional view of line III-III. [Figure 4] (a) shows a cross-sectional view of IV-IV in Figure 2, and (b) shows how the upper and lower engagement portions of different cone bars engage with each other. [Figure 5] This shows how multiple cone bars are transported. [Modes for carrying out the invention]

[0010] The following describes an embodiment of the cone bar with reference to the drawings.

[0011] As shown in Figure 1, the cone bar 100 is configured to be connected to the cone 9 to demarcate the designated area A.

[0012] Designated area A is an artificially established area, which may be set up, for example, at a construction site or event venue. The cone bar 100 serves as a boundary, restricting the movement of people between designated area A and the outside area.

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

[0014] By arranging multiple cones 9 as described above along the boundary of designated area A, and connecting adjacent cones 9 with cone bars 100, designated area A can be demarcated.

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

[0016] As shown in Figure 2, the cone bar 100 comprises a long main body portion 1 and a cone connection portion 2 provided at least one of the two ends of the main body portion 1 in the longitudinal direction. In the illustrated example, the cone connection portions 2 are provided at both ends of the main body portion 1 in the longitudinal direction.

[0017] The cone connection portion 2 includes an inserted portion 24 into which a tip of a cone 9 is inserted. The tip of the cone 9 is inserted into the inserted portion 24 by dropping the inserted portion 24 of the cone connection portion 2 downward onto the tip of the cone 9 placed on the ground 70 (see FIG. 1). By performing the same operation on the opposite side of the cone bar 100, adjacent cones 9 can be connected to each other via the cone bar 100. In the illustrated example, a ring-shaped inserted portion 24 is shown; however, the present invention is not limited thereto, and the inserted portion 24 may have a shape in which a part of the ring is discontinuous, such as a C-shape, for example.

[0018] The main body portion 1 defines a boundary of a designated area A. Therefore, to make it easily recognizable as the boundary of the designated area A (to improve visibility), the surface of the main body portion 1 may be alternately coated with black and yellow, or a light or a reflector may be provided thereon.

[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 planar portions S that face opposite sides to each other and are formed in a planar shape.

[0020] Since the target planar portions S are formed in a planar shape, when the cone bar 100 is not installed in the designated area A (hereinafter simply referred to as "when not installed"), placing the target planar portions S on a floor, a stand, or the like makes it easy to stabilize the entire cone bar 100. Furthermore, since the pair of target planar portions S are provided to face opposite sides to each other, when stacking a plurality of cone bars 100 together during non-installation, the target planar portions S of different cone bars 100 can be brought into surface contact with each other, making it easy to ensure stacking stability.

[0021] The main body portion 1 and the cone connecting portion 2 are arranged on a concentric axis. The diameter of the main body portion 1 is smaller than the diameter of the cone connecting portion 2. Therefore, for example, when placing the cone bar 100 on the ground 70, the cone connecting portion 2 comes into contact with the ground 70. Accordingly, in the present embodiment, at least the cone connecting portion 2 is provided with a pair of target flat portions S. In this way, the pair of target flat portions S is provided on the cone connecting portion 2, which has many opportunities to contact another object (e.g., the ground 70), so that it is easy to stabilize the contact with the other object.

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

[0023] As shown in FIG. 3, in the present embodiment, the cross-section of the main body portion 1 in a plane orthogonal to the longitudinal direction is formed in a square shape. Two opposing sides among the four sides of the square shape are the main body-side target flat portions 10. The other two sides are non-target surface portions 13. In this example, since the cross-section of the main body portion 1 is square, the pair of non-target surface portions 13 which are the other two sides are also formed in a flat shape.

[0024] FIG. 4(a) is a cross-sectional view taken along line IV-IV in FIG. 2.

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

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

[0027] In this embodiment, the upper engaging portion 210 includes a convex portion 211 that protrudes outward (upward) from the upper symmetrical plane portion 21 and a concave portion 212 that recesses inward (downward) from the upper symmetrical plane portion 21. The lower engaging portion 220 includes a convex portion 221 that protrudes outward (downward) from the lower symmetrical plane portion 22 and a concave portion 222 that recesses inward (upward) from the lower symmetrical plane portion 22.

[0028] Furthermore, the protrusion 221 of the lower engaging portion 220 is positioned to overlap with the recess 212 of the upper engaging portion 210 when viewed in the vertical direction. The recess 222 of the lower engaging portion 220 is positioned to overlap with the protrusion 211 of the upper engaging portion 210 when viewed in the vertical direction. In other words, the upper engaging portion 210 and the lower engaging portion 220 have a staggered structure in which the positions of the protrusions (211, 221) and recesses (212, 222) are swapped with each other.

[0029] With this configuration, as shown in Figure 4(b), when stacking different cone bars 100 vertically, at the first position P1 in the figure, the convex portion 211 of the upper engaging portion 210 of the lower cone bar 100 and the concave portion 222 of the lower engaging portion 220 of the upper cone bar 100 engage with each other. At the same time, at the second position P2, which is different from the first position P1, the concave portion 212 of the upper engaging portion 210 of the lower cone bar 100 and the convex portion 221 of the lower engaging portion 220 of the upper cone bar 100 engage with each other. Thus, in this embodiment, the upper engaging portion 210 and the lower engaging portion 220 have complementary shapes. With this configuration, the degree of freedom in the engagement manner between the upper engaging portion 210 and the lower engaging portion 220 is increased, making it possible to stack different cone bars 100 without worrying about their orientation.

[0030] In this embodiment, the protrusions (211, 221) are formed in the shape of a rectangular parallelepiped. The recesses (212, 222) that fit into them are formed to match the size of the corresponding protrusions (211, 221).

[0031] In this embodiment, the size of the recesses (212, 222) is formed to be the same as the size of the corresponding protrusions (211, 221). This ensures a strong fit between the two.

[0032] On the other hand, the size of the recesses (212, 222) may be made larger than the size of the corresponding protrusions (211, 221). This allows for a more generous fit between the two, making it easier to attach and detach different cone bars 100, thus improving work efficiency. In this case, it is preferable to make the protruding length of the protrusions (211, 221) longer than usual. This improves the ease of attachment and detachment while preventing the protrusions (211, 221) from unintentionally coming loose when they are fitted into the recesses (212, 222).

[0033] In this embodiment, the recesses (212, 222) are through holes that penetrate a part of the cone connection portion 2 (the symmetrical planar portion 20 on the connection side). However, the configuration is not limited to this. The recesses (212, 222) only need to be configured such that the corresponding protrusions (211, 221) fit into them, so they may be, for example, bottomed holes (simple indentations).

[0034] As described above, the cone bar 100 is easy to handle when not installed in designated area A. For example, when placing the cone bar 100 on the ground 70, even if the cone connection part 2, rather than the main body part 1, is in contact with the ground 70, the posture of the cone bar 100 can be stabilized by making the connecting side symmetrical plane part 20 provided on the cone connection part 2 make surface contact with the ground 70.

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

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

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

[0038] (1) In the above embodiment, an example was described in which the cross-section of the main body 1 is rectangular. However, the main body 1 is not limited to such an example, and only if it is provided with at least one pair of symmetrical planar parts S, the shape of the other parts (non-symmetrical surface parts 13) can be designed arbitrarily. For example, the non-symmetrical surface parts 13 may have one or more corners, or they may be formed in a curved shape. Alternatively, at least a part of the non-symmetrical surface parts 13 may have ridge-like uneven surfaces that follow the vertical direction (up and down direction) to match the shape of a person's hand.

[0039] (2) In the above embodiment, an example was described in which the protrusions (211, 221) of the upper engaging portion 210 and the lower engaging portion 220 are formed in a rectangular parallelepiped shape. However, the embodiment is not limited to this example, as the protrusions (211, 221) only need to protrude from the target planar portion S, for example, they may be partially or entirely rounded, or they may be wedge-shaped.

[0040] (3) In the above embodiment, an example was described in which there is only one protrusion (211, 221) on each of the upper engaging portion 210 and the lower engaging portion 220. However, the invention is not limited to this example, and there may be multiple protrusions (211, 221) on each. In this case, the same number of recesses (212, 222) corresponding to the protrusions (211, 221) are provided.

[0041] (4) In the above embodiment, an example was described in which the upper engaging portion 210 and the lower engaging portion 220 each have interlocking convex portions (211, 221) and concave portions (212, 222), and engage by interlocking. However, the embodiment is not limited to this example, and the upper engaging portion 210 and the lower engaging portion 220 each may be made of a magnetic material and configured to engage with each other by magnetic force.

[0042] (5) The configurations disclosed in the embodiments described above can be applied in combination with configurations disclosed in other embodiments, as long as no inconsistencies arise. With regard to other configurations, the embodiments disclosed herein are merely illustrative in all respects. Therefore, various modifications can be made as appropriate without departing from the spirit of this disclosure.

[0043] [Summary of this embodiment] The following is a summary of this embodiment.

[0044] A cone bar connected to a cone to demarcate a designated area, The main body is elongated, The main body comprises a cone connection portion provided at least one of the two ends in the longitudinal direction of the main body, At least one of the main body portion and the cone connection portion is provided with a pair of symmetrical planar portions that face opposite each other and are formed in a planar shape.

[0045] With this configuration, since the target plane is formed in a flat shape, the entire cone bar can be easily stabilized by placing the target plane on a surface such as a floor or table. Furthermore, because the pair of target planes are provided facing opposite directions, when multiple cone bars are bundled together, the target planes of different cone bars can be brought into surface contact, making it easier to ensure the stability of the bundle. For example, it becomes easy to stack multiple cone bars in the vertical direction. Thus, with this configuration, handling of the cone bar becomes easier when it is not installed in a designated area, such as during storage or transportation.

[0046] It is preferable that a pair of the aforementioned symmetrical planar portions is provided at least on the cone connection portion.

[0047] If the diameter of the main body is smaller than the diameter of the cone connection part, the cone connection part is more likely to come into contact with the floor. Also, when multiple cone bars are bundled together, the cone connections of different cone bars are more likely to come into contact with each other. With this configuration, a pair of symmetrical planes are provided at the cone connection part, which is frequently in contact with other objects (such as the floor or other cone bars), making it easier to stabilize contact with other objects.

[0048] Of the pair of symmetrical planar portions provided in the cone connection portion, the symmetrical planar portion facing upward is designated as the upper symmetrical planar portion, and the symmetrical planar portion facing downward is designated as the lower symmetrical planar portion. The upper symmetrical plane portion is provided with an upper engaging portion configured to engage with the lower symmetrical plane portion of the other cone bar. Preferably, the lower symmetrical plane portion is provided with a lower engaging portion configured to engage with the upper symmetrical plane portion of another cone bar.

[0049] With this configuration, when combining multiple cone bars, the stability of the combined structure can be more easily ensured by engaging the upper and lower engaging parts of different cone bars.

[0050] It is preferable that the upper engaging portion and the lower engaging portion have complementary shapes.

[0051] This configuration increases the degree of freedom in the engagement configuration between the upper and lower engaging parts, making it possible, for example, to connect different cone bars without worrying about their orientation. [Industrial applicability]
