Description

[Technical Field]

[0001] The present invention relates to a bollard that is installed in garages, parks, the boundary between roads and sidewalks, etc., and in particular to a pole-shaped bollard that is erected from the ground surface with its lower part buried underground. [Background technology]

[0002] Patent Document 1 describes a pole-shaped car stopper that stands upright on the ground with its lower part buried underground, and that includes a cylindrical outer tube (first cylindrical body) made of metal, a cylindrical core member (second cylindrical body) with a smaller diameter than the outer tube, and multiple cylindrical reinforcing members (third cylindrical bodies) with an even smaller diameter than the core member. The core member is disposed inside the outer tube coaxially with the outer tube, and the multiple reinforcing members are disposed between the outer tube and the core member so as to be in contact with each other and aligned circumferentially around the outer tube. By disposing the core member and multiple reinforcing members inside the outer tube, which is the main body of the car stopper, the strength of the car stopper can be improved.

[0003] [Patent Document 1] Patent Publication No. 2021-55327 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when manufacturing multiple types of car bumpers with different outer cylinder diameters as described in Patent Document 1, it may be necessary to use multiple types of reinforcing members with different diameters depending on the diameters of the outer cylinders. In order to manufacture multiple types of cylindrical reinforcing members with different diameters, it is necessary to prepare multiple types of long metal plate materials with different widths as materials for the reinforcing members, which makes material management complicated.

[0005] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a bollard that, even when manufacturing multiple types of bollards with different outer tube diameters, does not require the preparation of multiple types of metal plate material with different sizes as materials for the reinforcing members, making it easier to manage materials during manufacturing and simplifying manufacturing. [Means for solving the problem]

[0006] The car stopper disclosed in the present application comprises an outer cylinder and a plurality of reinforcing members. The outer cylinder extends vertically with a portion of the outer cylinder buried in the ground. The plurality of reinforcing members are arranged circumferentially inside the outer cylinder and each extend vertically. Each of the plurality of reinforcing members is formed from a metal plate and has two flat leg portions and a central portion between the two leg portions. The central portion is located radially inward of the outer cylinder relative to the two leg portions.

[0007] In the car stopper disclosed in the present application, the distance between the two legs increases radially outward from the outer cylinder, and each of the two legs abuts against one of the two legs of another reinforcing member that is adjacent to the outer cylinder in the circumferential direction.

[0008] In addition, in the car stopper disclosed in the present application, the outer cylinder is cylindrical, and the central portions of the plurality of reinforcing members are flat and arranged along an arc coaxial with the outer cylinder.

[0009] In the car stopper disclosed in the present application, 4 to 18 of the plurality of reinforcing members are arranged in the circumferential direction of the outer cylinder. [Effects of the Invention]

[0010] According to the car stopper of the present invention, even when manufacturing multiple types of car stops with different outer tube diameters, there is no need to prepare multiple types of metal plate material of different sizes as material for the reinforcing member, making it easier to manage materials during manufacturing and simplifying manufacturing.

[0012] The car stopper according to the embodiment of the present invention will be described in detail below with reference to the drawings. Note that the embodiment described below is a preferred example for carrying out the present invention, and therefore various technical limitations are imposed, but the present invention is not limited to this embodiment unless otherwise specified in the following description to the effect that the invention is limited.

[0013] <Embodiment> A car stopper according to an embodiment of the present invention will be described below with reference to Fig. 1 to Fig. 3. Fig. 1 is a vertical cross-sectional view showing a car stopper according to a first embodiment of the present invention. Fig. 2 is a cross-sectional view taken along the line AA in Fig. 1. Fig. 3 is a cross-sectional view taken along the line BB in Fig. 1.

[0014] As shown in Figures 1 and 2, the car stopper of this embodiment is pole-shaped overall and comprises an outer tube 10, multiple reinforcing members 20, and a head portion 30, and is fixed to the ground with its lower portion buried underground G.

[0015] The outer cylinder 10 extends vertically with its lower portion buried in the ground. In this embodiment, the outer cylinder 10 is cylindrical, with its lower end open and its upper end closed by a mounting plate 11 of the head portion 30. As shown in FIG. 3 , the head portion 30 is fixed to the mounting plate 11 with a plurality of bolts 12.

[0016] As shown in Figures 1 and 2, the multiple reinforcing members 20 are arranged inside the outer cylinder 10 in the circumferential direction of the outer cylinder 10, and each extends in the up-down direction. Each of the multiple reinforcing members 20 is formed from a metal plate and has two flat leg portions 21 and a central portion 22 between the two leg portions 21. The central portion 22 is positioned radially inward of the two leg portions 21 on the outer cylinder 10. It is preferable that the number of multiple reinforcing members 20 be 4 to 18, as this reduces the amount of work required to assemble the car bollard, prevents the number of parts from becoming too large, and simplifies the manufacture of the car bollard.

[0017] In the embodiment, the central portion 22 is flat and aligned along an arc R coaxial with the outer cylinder 10. Each of the reinforcing members 20 has a U-shaped cross section, and the two leg portions 21 are formed by bending both sides of a long metal plate material by the same width in the same direction, leaving a width corresponding to the central portion 22. The two leg portions 21 are connected to both sides of the central portion 22 and extend radially outward from both sides of the central portion 22 of the outer cylinder 10.

[0018] The distance between the two legs 21 increases radially outward from the outer cylinder 10, and the directions in which the two legs 21 extend radially outward from both sides of the central portion 22 of the outer cylinder 10 are not parallel but are inclined at a predetermined angle from a direction perpendicular to the flat central portion 22. Each of the two legs 21 abuts against one of two legs 21 of another reinforcing member 20 adjacent to it in the circumferential direction of the outer cylinder 10. In this embodiment, the outer surfaces of the legs 21 abut against each other entirely, and the multiple reinforcing members 20 are integrated by bonding the abutting legs 21 together by welding or the like near the upper and lower ends in the longitudinal direction.

[0019] 1 and 2, the positions of the multiple reinforcing members 20 inside the outer cylinder 10 are fixed by multiple short bolts 23 and one long bolt 24. In this embodiment, as shown in FIG. 1, the overall length of the multiple reinforcing members 20 is shorter than the overall length of the outer cylinder 10, the lower ends of the multiple reinforcing members 20 coincide with the lower end of the outer cylinder 10, and the upper ends of the multiple reinforcing members 20 are spaced apart from the mounting plate 11 at the upper end of the outer cylinder 10.

[0020] In the embodiment shown in Fig. 2, the two leg portions 21 extend radially outward from both sides of the central portion 22 along lines L1 and L2 that are perpendicular to the central axis I of the cylindrical outer cylinder 10 and tangent to both ends of the central portion 22. In the example of Fig. 2, the angle formed by lines L1 and L2 is 30 (= 360 ÷ 12) degrees because the number of reinforcing members 20 arranged in the circumferential direction of the outer cylinder 10 is "12." Therefore, if the number of reinforcing members 20 arranged in the circumferential direction of the outer cylinder 10 changes, the angle formed by lines L1 and L2 also changes, and the angle formed by the two leg portions 21 with respect to each other also changes.

[0021] 1 to 3, in the car stopper of this embodiment, a plurality of reinforcing members 20 are arranged inside the outer cylinder 10 in the circumferential direction of the outer cylinder 10, and each extends in the up-down direction. Each of the plurality of reinforcing members 20 is formed from a metal plate, and has two flat leg portions 21 and a central portion 22, with the central portion 22 being disposed radially inward of the two leg portions 21 on the outer cylinder 10.

[0022] When manufacturing multiple types of bollards with different diameters of the outer cylinder 10, if the multiple reinforcing members (third cylindrical bodies) are cylindrical, as in Patent Document 1, it may not be possible to arrange the multiple reinforcing members in contact with each other in the circumferential direction of the outer cylinder (first cylindrical body) for each size of bollard, simply by adjusting the number of reinforcing members. In such cases, it is necessary to use multiple types of cylindrical reinforcing members with different diameters depending on the diameter of the outer cylinder, and it is necessary to prepare multiple types of long metal plate material with different widths as material for the reinforcing members, which makes material management when manufacturing the bollards complicated.

[0023] According to the embodiment of the car stopper, even when multiple types of reinforcing members 20 having different sizes in the circumferential direction of the outer tube 10 according to the diameter of the outer tube 10 are used to manufacture multiple types of car stoppers with different diameters of the outer tube 10, it is possible to arrange the multiple reinforcing members 20 without gaps in the circumferential direction of the outer tube 10 simply by adjusting the width of the central portion 22 of the reinforcing member 20, the length of the two leg portions 21 in the radial direction of the outer tube 10, and the angle formed by the two leg portions 21 relative to each other according to the number of reinforcing members 20. This eliminates the need to prepare multiple types of metal plate material with different sizes such as width as materials for the reinforcing members 20, making it easier to manage materials during manufacturing and simplifying the manufacturing of car stoppers.

[0024] 1 to 3, according to the car stopper of this embodiment, the two legs 21 are spaced apart radially outward from the outer cylinder 10, and each abuts against one of the two legs 21 of another reinforcing member 20 that is adjacent in the circumferential direction of the outer cylinder 10. Therefore, the mutual engagement of the multiple reinforcing members 20 makes it possible to hold the multiple reinforcing members 20 in fixed positions inside the outer cylinder 10, and there is no need to use a structure in which all of the reinforcing members are fixed to the outer cylinder, which is the main body, as in Patent Document 1, which simplifies the structure and makes it even easier to manufacture the car stopper.

[0025] 1 to 3, according to the car stopper of this embodiment, the outer cylinder 10 is cylindrical, and the central portions 22 of the multiple reinforcing members 20 are flat and aligned along an arc R coaxial with the outer cylinder 10. Therefore, without having to install a core member (second cylindrical body) with a smaller diameter than the outer cylinder (first cylindrical body) inside the outer cylinder as in Patent Document 1, it is possible to obtain a reinforcing effect similar to that achieved when a core member is provided by the central portions 22 of the multiple reinforcing members 20, thereby suppressing an increase in the number of parts, facilitating material management during manufacturing, and further simplifying the manufacture of the car stopper.

[0026] Furthermore, as explained with reference to Figure 1, according to the car stopper of this embodiment, the total length of the multiple reinforcing members 20 is shorter than the total length of the outer tube 10, and the lower ends of the multiple reinforcing members 20 are aligned with the lower end of the outer tube 10, thereby effectively reinforcing the lower and central parts of the car stopper, which are in great need of reinforcement, while minimizing the increase in weight due to the installation of the multiple reinforcing members 20.

[0027] Next, another embodiment of the present invention will be described with reference to Fig. 4. Fig. 4 is a vertical cross-sectional view showing a car stopper according to a second embodiment of the present invention.

[0028] As shown in Fig. 4, in this embodiment, multiple reinforcing members 20A have a cross-sectional shape similar to that of the embodiment shown in Fig. 2 and have a longer overall length than the multiple reinforcing members 20 of the above embodiment. The lower ends of the multiple reinforcing members 20A coincide with the lower end of the outer cylinder 10, as with the multiple reinforcing members 20 of the above embodiment, but the upper ends of the multiple reinforcing members 20A abut against the mounting plate 11 of the head portion 30, unlike the multiple reinforcing members 20 of the above embodiment. Therefore, according to the car stopper of this embodiment, not only the lower and central parts of the car stopper but also the upper part of the car stopper can be reinforced by the multiple reinforcing members 20A, further improving the strength of the car stopper.

[0029] Next, still another embodiment of the present invention will be described with reference to Fig. 5. Fig. 5 is a cross-sectional view similar to Fig. 2, showing a car stopper according to a third embodiment of the present invention.

[0030] 5, in this embodiment, each of the multiple reinforcing members 20B is formed from a metal plate, has a U-shaped cross section, and includes two flat leg portions 21B and a central portion 22B between the two leg portions 21B. The central portion 22B is also flat, and is disposed radially inward of the two leg portions 21B in the outer cylinder 10, and is aligned along an arc R1 coaxial with the cylindrical outer cylinder 10.

[0031] In addition, the distance between the two legs 21B increases radially outward from the outer tube 10, and the two legs 21B each abut against one of the two legs 21B of another reinforcing member 20B adjacent to them in the circumferential direction of the outer tube 10.

[0032] The number of reinforcing members 20B arranged circumferentially around the outer tube 10 is smaller than that in Figure 2, the length of the two leg portions 21B in the radial direction of the outer tube 10 is longer than the two leg portions 21 of the reinforcing member 20 in Figure 2, and the width of the central portion 22B of the reinforcing member 20B is also larger than the width of the central portion 22 of the reinforcing member 20 in Figure 2.

[0033] Furthermore, the positions of the multiple reinforcing members 20B inside the outer cylinder 10 are fixed by multiple short bolts 23 and one long bolt 24.

[0034] In addition, the two leg portions 21B extend radially outward from both sides of the central portion 22B along straight lines L11 and L12 that are perpendicular to the central axis I of the cylindrical outer cylinder 10 and tangent to both side ends of the central portion 22B.

[0035] The angle formed by the lines L11 and L12 is 60 (=360÷6) degrees because the number of reinforcing members 20B arranged circumferentially around the outer tube 10 is "6", and the angle formed by the two legs 21B with each other is also 60 degrees.

[0036] With the above-described configuration, the car stopper of this embodiment also achieves the same effect as the car stopper of Figures 1 to 3, and since the number of multiple reinforcing members 20B is smaller than that of the car stopper of Figures 1 to 3, the number of parts and the number of operations during assembly can be reduced, and manufacturing can be further simplified.

[0037] Next, still another embodiment of the present invention will be described with reference to Fig. 6 and Fig. 7. Fig. 6 is a vertical cross-sectional view showing a car stopper according to a fourth embodiment of the present invention. Fig. 7 is a cross-sectional view taken along the CC arrow in Fig. 6.

[0038] 6 and 7, in this embodiment, each of the multiple reinforcing members 20C is formed from a metal plate, has a U-shaped or V-shaped cross section, and includes two flat leg portions 21C and a central portion 22C between the two leg portions 21C. The lower ends of the multiple reinforcing members 20C are aligned with the lower end of the outer tube 10, and the upper ends of the multiple reinforcing members 20C abut against the mounting plate 11 at the upper end of the outer tube 10, as in the embodiment of FIG.

[0039] The number of reinforcing members 20B arranged in the circumferential direction of the outer cylinder 10 is "8," the length of the two leg portions 21C in the radial direction of the outer cylinder 10 is longer than the two leg portions 21B of the reinforcing member 20B in Fig. 5, and the width of the central portion 22C is smaller than the width of the central portion 22B of the reinforcing member 20B in Fig. 5. The central portion 22C has a curved plate shape and is arranged radially inward of the two leg portions 21C of the outer cylinder 10.

[0040] A rectangular auxiliary plate 25 is attached to one pair of the reinforcing members 20C, and the positions of the reinforcing members 20C inside the outer cylinder 10 are fixed by a plurality of short bolts 23 and one long bolt 24. The auxiliary plate 25 has a female screw hole (not shown) that screws into the short bolt 23, and both side portions are welded to the inner surfaces of the two leg portions 21C.

[0041] The two leg portions 21C each abut one of two leg portions 21C of another reinforcing member 20C adjacent to it in the circumferential direction of the outer cylinder 10. The two leg portions 21C also extend radially outward from both sides of the central portion 22C along straight lines L21 and L22 that are perpendicular to the central axis I of the cylindrical outer cylinder 10 and tangent to both ends of the central portion 22C. The angle formed by the straight lines L21 and L22 is 45 (=360÷8) degrees because the number of reinforcing members 20 arranged in the circumferential direction of the outer cylinder 10 is "8", and the angle formed by the two leg portions 21C with each other is also 45 degrees.

[0042] With the above configuration, the reinforcing member 20C is not limited to a reinforcing member having a U-shaped cross section, but may have a U-shaped or V-shaped cross section and the central portion 22C is curved rather than flat, and even when manufacturing multiple types of bollards with different diameters of the outer tube 10, as in the embodiments of Figures 1 to 5, there is no need to prepare multiple types of metal plate material with different sizes as material for the reinforcing member 20C, making it easier to manage materials during manufacturing and simplifying manufacturing.

[0043] The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 7). However, the present invention is not limited to the above embodiments and can be embodied in various forms without departing from the spirit and scope of the present invention.
