Description

[Technical field]

[0001] The present invention relates to an isolation system. [Background technology]

[0002] For example, it is known to use gate-shaped posts formed by connecting the tops of adjacent posts as a protective fence, as described in Patent Document 1. Such posts are installed at the boundary between a pedestrian and a roadway, and are made of a round metal pipe such as a steel pipe to prevent vehicles from entering the sidewalk. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-150890 A Summary of the Invention [Problem to be solved by the invention]

[0004] Because these posts are made of metal, it is not desirable to install them inside roadways or in roadway training zones (commonly known as zebra zones) in consideration of the risk of contact with vehicles, etc. On the other hand, when multiple gate-shaped posts are used as a protective fence, gaps will form between adjacent gates. These gaps are undesirable because they allow people to enter and exit the roadway, for example.

[0005] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide an isolation system that can be installed anywhere and does not form gaps. [Means for solving the problem]

[0007] In one embodiment of the blocking system, the column member comprises a column-shaped column body and a base portion supporting a lower end of the column body.

[0008] In one embodiment of the isolation system, the post members are made from polyurethane.

[0009] In one embodiment, the extension member has a flexibility that allows the extension member to be restored to a desired shape. In one example, the extension member is made of polyurethane.

[0010] In one embodiment of the isolation system, the attachment member is made from polyurethane.

[0011] In one embodiment of the blocking system, the mounting member includes a main body portion that is attached to the outer peripheral surface of the pillar member, a convex portion is formed on the inner peripheral surface of the main body portion, and a concave portion into which the convex portion fits is formed on the outer peripheral surface of the pillar member.

[0012] In one embodiment of the blocking system, a plurality of pairs of the convex portion and the concave portion are provided in the circumferential direction of the outer circumferential surface of the pillar member.

[0013] In one embodiment of the isolation system, the mounting member includes a support portion that supports an end of the extension member, and a plurality of the support portions are provided around the axis of the pillar member.

[0014] In one embodiment of the isolation system, a plurality of the extension members extend between an adjacent pair of the post members. Effect of the Invention

[0015] According to the present invention, it is possible to provide an insulating system which can be installed anywhere and does not form gaps. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0018] FIG. 1 is a front view showing a schematic structure of an isolation system 1 according to an embodiment of the present invention. FIG. 2 is a plan view showing a schematic structure of an isolation system 1 according to an embodiment of the present invention. As shown in FIG. 1 and FIG. 2, the isolation system 1 includes a plurality of pole members 10, three pole members in this example, at least one extension member 20, two extension members in this example, extending between a pair of adjacent pole members 10, and at least one attachment member 30, two attachment members in this example, attached to each pole member 10 and supporting an end of the extension member 20. The isolation system 1 is fixedly installed on, for example, a flat ground G. In this example, all of the pole members 10 are installed on the flat ground G at the same height.

[0019] FIG. 3 is an enlarged front view of the barrier system 1 showing one of the pole members 10 in an enlarged manner. With reference to FIGS. 1 to 3, the pole member 10 is, for example, a road sign pole such as a Post Cone (registered trademark). The pole member 10 supports an extension member 20 in one direction intersecting the axis of the pole member 10. Each pole member 10 has a pole body 11 and a base 12 supporting the pole body 11. The pole body 11 extends in a cylindrical shape in the vertical direction. The pole body 11 has an upper end 13 which is the upper end, a lower end 14 which is the lower end, and a cylindrical outer circumferential surface 15 defined between the upper end 13 and the lower end 14. The pole body 11 may be hollow or solid. The pole body 11 is supported at its lower end 14 in a recess 16 formed in the base 12. A plurality of reflective sheets (not shown) extending in the circumferential direction may be provided in the vertical direction on the outer circumferential surface 15.

[0020] The pillar body 11 has flexibility that allows it to be deformed in a restorable manner. Specifically, for example, it has flexibility that allows it to be deformed even when it is subjected to an impact of a person touching it. In addition, the pillar body 11 has the restoring ability to return to its original shape or approximately its original shape when the external force is removed after it has been deformed by the external force. The pillar body 11 is made of an elastic material having such flexibility, such as polyurethane. Note that the pillar body 11 may be made of other elastic materials such as other resin materials and rubber having such flexibility.

[0021] The base 12 is a part that functions as a pedestal, and spreads outward in the radial direction from the column body 11. The radial direction is a direction perpendicular to the up-down direction in which the column body 11 extends. The base 12 has, for example, a disk shape, and has a bottom surface 17 as a grounding surface and the aforementioned recess 16 formed at a position facing away from the bottom surface 17. With the lower end 14 of the column body 11 housed in the recess 16, the lower end 14 of the column body 11 is fixed to the base 12 by a plurality of fastening parts (not shown), such as bolts. The fastening parts are screwed into the column body 11 in the radial direction, for example. The base 12 may be made of polyurethane, similar to the column body 11.

[0022] The base 12 may be fixed to the ground G by a plurality of fastening parts (not shown), such as bolts protruding downward from the bottom surface 17 of the base 12. The fastening parts are screwed into the ground in the vertical direction, for example. With this configuration, the pole member 10 can stand reliably even when subjected to wind generated by a traveling vehicle, for example. Note that instead of the fastening parts, a weight (not shown) may be housed in the base 12. The weight may be embedded in the base 12, or may be exposed on the surface of the base 12. The weight is made of, for example, a metal material. With such a weight, the pole member 10 can stand on the ground G even if the base 12 is not fixedly installed on the ground G.

[0023] A plurality of extension members 20, two in this example, extend between a pair of adjacent column members 10, 10. The upper extension member 20 is disposed adjacent to the upper end 13 of the column member 10. Meanwhile, the lower extension member 20 is disposed adjacent to an intermediate position between the upper end 13 and the lower end 14. Each extension member 20 has an extension portion 21 extending horizontally, for example, along the ground G, and ends, i.e., protruding portions 24, 25 protruding in opposite directions from both end faces 22, 23 of the extension portion 21 along the horizontal direction. The extension portion 21 extends, for example, in a cylindrical shape in the horizontal direction. The extension portion 21 may be hollow or solid. The extension member 20 may be made of polyurethane, similar to the column member 10.

[0024] FIG. 4 is an end view taken along line 4-4 in FIG. 3. Referring to FIGS. 1 to 4 together, the mounting member 30 has a main body 31 attached to the outer circumferential surface 15 of the column body 11 of the column member 10, and a support portion 32 continuing from the main body 31. In this example, the mounting member 30 has one support portion 32. In the end view of FIG. 4, the main body 31 has a C-shape with a part of the annular shape interrupted. The inner circumferential surface 33 of the main body 31 is in contact with or faces the outer circumferential surface 15 of the column body 11. The inner circumferential surface 33 is formed with a protrusion 34 that protrudes radially from the inner circumferential surface 33 to the inner circumferential side. In this example, four protrusions 34 are provided at equal angular intervals around the axis of the column body 11. The mounting member 30 may be made of polyurethane, similar to the column member 10 and the extension member 20.

[0025] On the other hand, on the outer peripheral surface 15 of the column main body 11, recesses 18 are formed at positions corresponding to the protrusions 34 of the main body 31 of the mounting member 30. In this example, four recesses 18 are provided corresponding to the four protrusions 34. The recesses 18 are formed in a shape that generally matches the shape of the protrusions 34. The protrusions 34 and the recesses 18 are formed, for example, in a rectangular column shape or a cylindrical shape having an axis in the radial direction. When the main body 31 of the mounting member 30 is attached to the column main body 11 of the column member 10, each protrusion 34 of the main body 31 fits into the recess 18 of the column main body 11. In this way, as will be described later, when the mounting member 30 is attached to the column member 10, the protrusions 34 are positioned in the recesses 18, making it easy to attach the mounting member 30 to the column member 10. In this way, a plurality of pairs of protrusions 34 and recesses 18 are provided in the circumferential direction of the outer peripheral surface 15 of the column member 10.

[0026] The support portion 32 is composed of a pair of support pieces 37, 38 extending horizontally from circumferentially opposing ends 35, 36 of the main body portion 31. The pair of support pieces 37, 38 face each other on their inner surfaces. A through hole 39 is formed in the support pieces 37, 38 penetrating in the horizontal direction. Meanwhile, the protruding portion 24 of the extension member 20 is sandwiched between the support pieces 37, 38. A through hole 26 corresponding to the through hole 39 is formed in the protruding portion 24. The protruding portion 24 of the extension member 20 is supported by the support portion 32 of the mounting member 30 with fastening parts including a bolt 50 passing through the through holes 39, 26 and a nut 51 screwed onto the bolt 50.

[0027] 5 is an end view taken along line 5-5 in FIG. 1. In the column member 10 in FIG. 5, two extension members 20, 20 are supported in two directions intersecting the axis of the column member 10. In this example, the two directions extend in opposite directions from the axis of the column member 10. With reference to FIGS. 1, 2 and 5, the mounting member 30 has a main body 31 that is interrupted at two points, that is, a first portion 31A and a second portion 31B. The first portion 31A and the second portion 31B have the same shape. The mounting member 30 is provided with a plurality of support portions 32, in this example, two support portions 32, around the axis of the column member 10.

[0028] The two support parts 32 are arranged at an angle interval of 180 degrees around the axis. That is, the mounting member 30 has two pairs of support pieces 37, 38 and support pieces 40, 41 that protrude in opposite directions in the horizontal direction. The support pieces 40, 41 extend in the horizontal direction from the other ends 42, 43 of the main body part 31, respectively. That is, the support pieces 37, 40 are provided on the first part 31A, and the support pieces 38, 41 are provided on the second part 31B. The support pieces 40, 41 are formed with a through hole 44 that penetrates in the horizontal direction. Thus, as described above, one of the support pieces 37, 38 supports one of the protruding parts 24 of the extension member 20, and the other of the support pieces 40, 41 supports the other of the protruding parts 25 of the extension member 20.

[0029] A scene in which the above-mentioned barrier system 1 is installed on the ground G will be described. First, each pole member 10 is fixed to the ground G at the planned installation location of the barrier system 1 using bolts or other joint parts. At this time, the interval between adjacent pole members 10, 10 is determined according to the length of the extension member 20. A predetermined mounting member 30 is attached to each pole member 10. For example, in the case of the mounting member 30 of FIG. 4, the pole body 11 is received in the main body part 31 by elastically deforming the main body part 31 so as to pull the support pieces 37, 38 away from each other. At this time, the convex part 34 of the inner peripheral surface 33 of the main body part 31 is fitted into the concave part 18 of the outer peripheral surface 15 of the pole body 11. In this way, the mounting member 30 is attached to the pole member 10.

[0030] Similarly, for example, in the case of the mounting member 30 of FIG. 5, the pole body 11 is disposed between the first portion 31A and the second portion 31B, and the convex portion 34 of the inner peripheral surface 33 of the body portion 31 is fitted into the concave portion 18 of the outer peripheral surface 15 of the pole body 11. In this manner, the mounting member 30 is mounted to the pole member 10. Thereafter, in the mounting member 30 of FIG. 4 and FIG. 5, the protruding portion 24 of the extension member 20 is disposed between the support pieces 37 and 38, while the protruding piece 25 of the extension member 20 is disposed between the support pieces 40 and 41. At this time, the through holes 39 and 26 or the through holes 44 and 26 are aligned with each other. Then, the protruding portions 24 and 25 are supported by the support portions 32 of the mounting members 30 by the bolts 50 and the nuts 51. In this manner, the blocking system 1 is established.

[0031] According to the above-described barrier system 1, the pole member 10, the extension member 20, and the mounting member 30 all have flexibility that allows them to be deformed in a restorable manner, so that even if a vehicle or the like contacts or collides with the barrier system 1, damage to the vehicle can be suppressed. As a result, it is possible to provide a barrier system 1 that can be installed anywhere. Moreover, the pole member 10, the extension member 20, and the mounting member 30 are all made of polyurethane, which is relatively lightweight. Therefore, even if the pole member 10 supports the extension member 20 and the mounting member 30, it is possible to prevent the pole member 10 from being deformed by the weight of the extension member 20 and the mounting member 30.

[0032] Moreover, since the blocking system 1 is established by extending at least one extension member 20 between a pair of adjacent pillar members 10, 10, no gaps are formed in the blocking system 1. As long as the extension member 20 is disposed between the adjacent pillar members 10, 10, the length of the blocking system 1 can be extended infinitely. Moreover, by adjusting the number and positions of the support parts 32 in the mounting member 30, the length of the extension member 20, etc., the shape and length of the blocking system 1 can be freely designed according to the installation location.

[0033] Fig. 6 is a plan view showing a schematic structure of an isolation system 1A according to a modified example of the present invention. In this isolation system 1A, in the pole member 10 in which the extension member 20 is supported in two directions intersecting the axis of the pole member 10, the two support parts 32 of the mounting member 30 extend in directions different from each other by, for example, 90 degrees. In this way, the isolation system 1A as a whole can take a form bent at 90 degrees in a plan view. In the example of Fig. 6, in the pole member 10 in which the extension member 20 is supported in two directions, the main body part 31 of the mounting member 30 has a first part 31A extending over an angular range of 90 degrees and a second part 31B extending over an angular range of 270 degrees in a plan view.

[0034] The number and angle range of the parts constituting the main body 31 and the number and positions of the support parts 32 may be appropriately changed according to the environment in which the blocking system 1, 1A is installed. For example, the main body 31 may be provided with three or more support parts 32 around the axis of the pole member 10. In that case, the main body 31 may be divided into an appropriate number of parts according to the number and positions of the support parts 32. In the mounting member 30 having the main body 31 divided into the first part 31A and the second part 31B, the first part 31A and the second part 31B may be partially connected to each other as long as either one of the support pieces can be pulled apart. For example, the other support pieces 40, 41 may be connected to each other at least on the inner circumferential side of the through hole 44.

[0035] FIG. 7 is a front view showing a schematic structure of an isolation system 1B according to another modified example of the present invention. In this isolation system 1B, for example, a pair of adjacent pole members 10, 10 are installed on the ground G including a slope S. As long as the through holes 26 of the protruding parts 24, 25 of the extension member 20 are aligned with the through holes 39, 44 of the support part 32 of the mounting member 30, the extension member 20 can swing around the axis of the bolt 50. In this way, the mounting member 30 can extend between the pair of pole members 10, 10 in a direction along the slope S, for example, by changing the angle of the mounting member 30 with respect to the axis of the pole member 10 around the axis of the bolt 50. As a result, the isolation system 1 can be installed on the ground G including the slope S without making any changes to the structures of the pole member 10, the extension member 20, and the mounting member 30.

[0036] Fig. 8 is a side view showing a schematic structure of an isolation system 1C according to another modified example of the present invention. In this isolation system 1C, the bottom surface 17 of the base 12 of the pole member 10 can be changed to an angle along the slope S, so that the pole member 10 can be made to stand upright in the vertical direction from the slope S. In this way, by changing the shape of the base 12 of the pole member 10, the isolation system 1C can be installed on the ground G including the slope S. Note that in Fig. 8, for example, the bottom surfaces 17 of the bases 12 of all the pole members 10 are changed to an angle along the slope S, so that the entire isolation system 1C is installed on the slope S.

[0037] FIG. 9 is a side view showing a schematic structure of an isolation system 1D according to another modified example of the present invention. In this isolation system 1D, the pillar body 11 is inclined with respect to the base 12 of the pillar member 10, so that the pillar member 10 can be made to stand upright in the vertical direction from the slope S. Specifically, the axis of the pillar body 11 is inclined at a predetermined angle with respect to the axis of the base 12. That is, the axis of the recess 16 of the base 12 is inclined at the angle with respect to the axis of the base 12. In this way, the isolation system 1D can be installed on the ground G including the slope S by changing the shape of the base 12 of the pillar member 10. In addition, in FIG. 9, as in FIG. 8, for example, the bottom surfaces 17 of the bases 12 of all the pillar members 10 are changed to an angle along the slope S, so that the entire isolation system 1C is installed on the slope S.

[0038] In the above-described blocking systems 1, 1A, 1B, 1C, and 1D, fastening parts such as bolts 50 and nuts 51 are used to attach the protrusions 24, 25 of the extension member 20 to the mounting member 30, but instead of these fastening parts, the protrusions 24, 25 of the extension member 20 may be welded to the mounting member 30. In addition, in the above-described embodiment, four recesses 18 are provided on the outer circumferential surface 15 of the column main body 11, but other numbers of recesses 18, for example, one, two, three, or five, may be provided. In addition, the extension portion 21 is formed in a cylindrical shape, but may be formed in a flat plate shape, or may be formed in other shapes.
