Description

[Technical field]

[0001] The present invention relates to a mounting structure for mounting a beam to a support. [Background technology]

[0002] Conventionally, when installing a safety fence on a sidewalk or road, a member is required to attach a beam to a post with one end buried in the ground. Safety fences are installed not only on flat ground, but also on sloped ground, stairs, and curved roads, so the posture of the member that attaches the post and the beam varies. It is possible to prepare different types of members depending on the installation form of the safety fence, but this may lead to an increase in the number of parts and complication of parts management, which may lead to an increase in costs. Therefore, a mounting bracket has been devised that uses multiple mounting brackets whose postures can be adjusted relative to each other, allowing the mounting angle of the beam to be adjusted relative to the post (see Patent Document 1).

[0003] [Patent Document 1] JP 2019-60174 A Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made in consideration of these circumstances, and one of its illustrative purposes is to provide a new mounting structure that enables a pillar or bracket to be mounted to a beam in a plurality of positions. [Means for solving the problem]

[0005] In order to solve the above problems, a mounting structure according to one aspect of the present invention is a mounting structure for mounting a beam to a post or bracket, and includes a holding member for holding the beam, and a supporting member configured to support the holding member in a plurality of positions. The supporting member is configured to be fixed to the post or bracket in a plurality of positions without the holding member.

[0006] According to this embodiment, the posts or brackets and the beams can be attached in a variety of positions, so that the safety fence or handrail can be installed in various locations using the same mounting structure regardless of its position.

[0007] A pair of holding members may be provided sandwiching the support member, thereby allowing beams to be installed on both sides from the posts or brackets.

[0008] The retaining member and the supporting member may both have a circular outer periphery and be connected in a straight line to the cylindrical beam. This allows the cross-sectional shapes of the beam and the mounting structure to be roughly uniform, resulting in a unified design with minimal surface irregularities.

[0009] The retaining member, the support member and the beam may be arranged so as not to cross the support posts. This makes it possible, when the beam is used as a handrail, to move around while holding the handrail with the hands without interfering with the support posts.

[0010] The retaining member and the supporting member may be cast parts manufactured in a casting mold, which allows for the production of rust-resistant members with complex shapes at low cost.

[0011] The holding member may have a spherical convex portion, a disk portion having one end face shaped like a mortar and the convex portion provided on the end face, and a semi-cylindrical portion provided on the opposite side of the disk portion to the convex portion and onto which the cylindrical beam is fitted. In this way, one end of the cylindrical beam is blocked by the disk portion, making it difficult for water, dust, and the like to enter the inside of the beam.

[0012] The support member is formed by fitting two semi-cylindrical parts of similar shapes together, and the semi-cylindrical parts may have hemispherical recesses at both ends into which the protrusions of the holding member fit. This makes it easier for the holding member to take various positions relative to the support member.

[0013] Any combination of the above components and any conversion of the present invention into a method, device, system, etc. are also valid aspects of the present invention. Effect of the Invention

[0014] According to the present invention, the posts or brackets can be attached to the beams in a number of positions. [Brief description of the drawings]

[0016] The present invention will be described below with reference to the drawings based on the embodiments. The same or equivalent components, members, and processes shown in each drawing are given the same reference numerals, and duplicated descriptions are omitted as appropriate. The embodiments are not intended to limit the invention, but are merely examples, and all features and combinations described in the embodiments are not necessarily essential to the invention. The mounting structure according to this embodiment is for mounting and fixing beams to posts fixed to the ground or brackets fixed to a wall, and can be used, for example, for safety fences on roads and sidewalks.

[0017] (First embodiment) Fig. 1 is a front view showing the schematic configuration of a prevention fence according to the first embodiment. The prevention fence 10 shown in Fig. 1 comprises multiple posts 12 each having one end fixed to the ground G, multiple beams 14 extending horizontally between the posts, and multiple mounting structures 16 for attaching the beams 14 to the posts 12.

[0018] Fig. 2 is a perspective view showing a state in which the mounting structure 16 according to the first embodiment holds the beam 14. Fig. 3 is a perspective view of the mounting structure 16 shown in Fig. 2 with some parts of the holding member omitted. The mounting structure 16 comprises a holding member 18 that holds the beam 14, and a support member 20 configured to be able to support the holding member 18 in a plurality of positions. The support member 20 is configured to be able to be fixed to the support column 12 in a plurality of positions without the holding member 18. The support member 20 according to this embodiment is formed by fitting a pair of semi-cylindrical parts having substantially similar shapes together.

[0019] Fig. 4(a) is a perspective view of the first semi-cylindrical part, and Fig. 4(b) is a perspective view of the first semi-cylindrical part seen from a different direction than Fig. 4(a). Fig. 5 is a top view of the first semi-cylindrical part. Fig. 6 is a top view of the second semi-cylindrical part. The first semi-cylindrical part 20a and the second semi-cylindrical part 20b are mainly different in the shapes of the holes for the bolts for fitting and fastening them to each other, but the other shapes are almost the same.

[0020] The first semi-cylindrical part 20a is formed with a bolt hole 22 penetrating from the outer periphery to the center of the body part 21. The bolt hole 22 has a large diameter part 22a large enough to accommodate the head of the bolt so that the head of the bolt does not protrude from the first semi-cylindrical part 20a, and a small diameter part 22b through which the threaded part of the bolt passes. The small diameter part 22b has a smaller diameter than the large diameter part 22a, and may or may not have a female thread formed on the inner periphery.

[0021] Half-dome shaped connecting parts 24 are provided integrally with the body 21 on both sides of the body 21 of the first semi-cylindrical part 20a. A hemispherical recess 24a into which a protrusion of a holding member 18 described below fits is formed inside the connecting parts 24. On the side of the body 21 facing the second semi-cylindrical part 20b, there are formed a reference surface 25a which is the central cross section of the support member 20, a convex surface 25b which protrudes from the reference surface 25a, a concave surface 25c which is recessed from the reference surface 25a, and a concave surface 25d which is further recessed than the concave surface 25c.

[0022] Similarly, the second semi-cylindrical part 20b shown in Fig. 6 has a bolt hole 28 formed through the body 26 from the outer periphery toward the center. The bolt hole 28 is a place through which the threaded portion of the bolt passes, and may or may not have a female thread formed on the inner periphery. If the bolt hole 28 does not have a female thread, a hole with a female thread may be formed in part of the support 12.

[0023] Half-dome shaped connecting parts 30 are provided integrally with the body part 26 on both sides of the body part 26 of the second semi-cylindrical part 20b. A hemispherical recess 30a into which a protrusion of a holding member 18 described below fits is formed on the inside of the connecting parts 30. On the side of the body part 26 facing the first semi-cylindrical part 20a, a reference surface 32a which is the central cross section of the support member 20, a convex surface 32b which protrudes from the reference surface 32a, a concave surface 32c which is recessed from the reference surface 32a, and a concave surface 32d which is further recessed than the concave surface 32c are formed.

[0024] In the support member 20 according to the present embodiment, when the first semi-cylindrical part 20a and the second semi-cylindrical part 20b are assembled, the convex surface 25b of the first semi-cylindrical part 20a enters the concave surface 32c of the second semi-cylindrical part 20b, and the convex surface 32b of the second semi-cylindrical part 20b enters the concave surface 25c of the first semi-cylindrical part 20a, so that they are integrated at a predetermined position. As a result, the support member 20 becomes a member having a circular outer periphery. In addition, the support member 20 has a triangular slit 34 formed by the concave surface 25d of the first semi-cylindrical part 20a facing the concave surface 32d of the second semi-cylindrical part 20b (see FIG. 2). The support member 20 may be configured so that a part of the support or bracket enters the slit 34, so that the support member 20 is attached to the support or bracket.

[0025] Next, the holding member will be described in detail. Fig. 7(a) is a side view of the holding member according to this embodiment, Fig. 7(b) is a view of the holding member shown in Fig. 7(a) seen from direction A, Fig. 7(c) is a view of the holding member shown in Fig. 7(a) seen from direction B, and Fig. 7(d) is a view of the holding member shown in Fig. 7(a) seen from direction C.

[0026] 3 and 7, the retaining member 18 according to this embodiment has a spherical protrusion 36, a disk portion 38 having one end face 38a formed in a cone shape with the protrusion 36 provided on the end face 38a, and a semi-cylindrical portion 40 that is provided on the opposite side of the disk portion 38 from the protrusion 36 and into which the cylindrical beam 14 is extrapolated. A screw hole 42 is formed in the semi-cylindrical portion 40, through which a screw for fastening the beam 14 and the retaining member 18 to each other passes.

[0027] The outer diameter of the disc portion 38 and the inner diameter of the cylindrical beam material 14 are approximately the same, and as shown in Figure 2, by aligning the disc portion 38 of the retaining member 18 and the end of the beam material 14 and screwing them together, one end of the cylindrical beam material 14 is blocked by the disc portion 38, making it difficult for water, dust, etc. to enter the inside of the beam material 14.

[0028] 3, the holding member 18 is supported by the supporting member 20 by fitting the spherical protrusion 36 into the recess 24a of the first semi-cylindrical part 20a or the second semi-cylindrical part 20b. Since the connection part 24 of the supporting member 20 is dome-shaped and the end face 38a of the holding member 18 is cone-shaped, the holding member 18 can take various positions relative to the supporting member 20 with the protrusion 36 as the center.

[0029] The retaining member 18 and the supporting member 20 according to the present embodiment are made of cast parts manufactured in a mold. Stainless steel is an example of a casting material. This allows for rust-resistant and complex shaped members to be manufactured at low cost. In other words, the retaining member and the supporting member are preferably shaped so that they can be manufactured in a mold. In addition, the mounting structure 16 combining the retaining member 18 and the supporting member 20 allows the position of the retaining member 18 relative to the supporting member 20 to be freely changed to some extent, and the support 12 and the beam 14 can be mounted in a plurality of positions. As a result, the same mounting structure can be used to install the safety fence or handrail in various locations regardless of the position.

[0030] For example, the prevention fence 10 shown in Figure 1 uses six mounting structures 16 for attaching beams 14 to the posts 12. The mounting structures 16 for attaching the posts and beams 14 in the center and on the right side of Figure 1 are provided with a pair of holding members 18 sandwiching a support member 20, allowing the beams 14 to be installed on both sides from the posts 12.

[0031] On the other hand, in the mounting structure 16 for mounting the support 12 and beam 14 on the far left side of Fig. 1, the beam 14 is only on one side, so only one retaining member 18 is required to be supported by the support member 20. However, if the retaining member 18 is not provided at one connection part 24 of the support member 20, the recess 24a will be exposed, leaving room for improvement from a design standpoint. Therefore, we devised an end fitting that can be attached to the connection part 24 of the support member 20 instead of the retaining member 18.

[0032] Fig. 8(a) is a front view of an end fitting 44 according to this embodiment, and Fig. 8(b) is a DD cross-sectional view of the end fitting shown in Fig. 8(a). The end fitting 44 is a member having a cylindrical outer shape, and a semi-spherical protrusion 44b is provided on a bottom surface 44a. The protrusion 44b is shaped to fit into the recess 24a of the support member 20, and by attaching the end fitting 44 to the support member 20, the recess 24a of the support member 20 can be prevented from being exposed.

[0033] Additionally, the outer peripheries of multiple components such as end fittings 44, support members 20, and retaining members 18 are all circular and connected in a straight line to the cylindrical beam 14. This allows the cross-sectional shapes of the beam 14 and mounting structure 16 to be roughly uniform, resulting in a unified design with minimal surface irregularities. Additionally, the retaining members 18, support members 20, and beam 14 in this embodiment are positioned in front of (or behind) the support 12 so as not to intersect with the support 12. As a result, when the beam 14 is used as a handrail, the handrail is less likely to interfere with the support 12 even when the user moves while holding onto it.

[0034] Next, changes in the posture of the mounting structure due to differences in the installation location will be described in the following embodiments.

[0035] (Second embodiment) FIG. 9 is a front view showing a schematic configuration of a prevention fence according to a second embodiment. The prevention fence 10 shown in FIG. 2 includes a plurality of posts 12 each having one end fixed to the staircase S, a plurality of beams 14 extending horizontally between the posts, and a plurality of mounting structures 52 for mounting the beams 14 to the posts 12. The mounting structure 52 according to the second embodiment has the same configuration as the mounting structure 16 of the first embodiment, and differs only in the mounting attitude relative to the posts 12. That is, in order to provide the beams 14 along the staircase S, when the mounting structure 52 is mounted on the posts 12, the support member 20 is tilted and fixed with bolts or the like. This allows the same mounting structure to be used for the prevention fence 10 of FIG. 1 and the prevention fence 50 of FIG. 9.

[0036] (Third embodiment) Fig. 10 is a front view showing a schematic configuration of a prevention fence according to a third embodiment. A prevention fence 54 shown in Fig. 10 includes a plurality of posts 12 having one end fixed to the ground G, a plurality of posts 12 having one end fixed to a staircase S, a plurality of beams 14 extending horizontally between the posts, and a plurality of mounting structures 16, 52, 56 for mounting the beams 14 to the posts 12. The mounting structures 16, 52, 56 have the same configuration and differ only in the orientation when mounted to the posts.

[0037] As explained above with regard to the mounting structure 16, the support member 20 can support the holding members 18 on both sides in different postures. Therefore, in the mounting structure 56 according to this embodiment, one holding member 18 holds the beam 14 parallel to the ground G, and the other holding member 18 holds the beam 14 parallel to the slope of the stairs S. In this way, even in a prevention fence in which the beam 14 is inclined partway, the beam can be attached to the support using one type of mounting structure.

[0038] (Fourth embodiment) Fig. 11 is a front view showing a schematic configuration of a handrail according to a fourth embodiment, Fig. 12(a) is a side view of a bracket fixed to a wall, and Fig. 12(b) is a front view of the bracket fixed to the wall.

[0039] A handrail 58 shown in Fig. 11 comprises multiple brackets 60 fixed to a wall W, multiple beams 14 arranged horizontally between the brackets, and multiple mounting structures 52 for attaching the beams 14 to the brackets 60. The brackets 60 have a flat plate portion 64 in which multiple screw holes 62 are formed through which screws can be passed to fasten the brackets to the wall W, and a hook 66 provided to protrude from the flat plate portion 64. A bolt hole 68 is formed at the tip side of the hook 66.

[0040] The hook 66 enters the triangular slit 34 in the support member 20 of the mounting structure 52 and is fixed to the mounting structure 52 by a screw. At this time, by adjusting the attitude of the mounting structure 52 relative to the hook 66, the bracket 60 and the beam 14 can be attached in a variety of positions. As a result, the handrail 58 can be installed in various locations using the same mounting structure regardless of the position of the handrail 58.

[0041] (Fifth embodiment) Fig. 13 is a top view showing the schematic configuration of a prevention fence according to a fifth embodiment. Prevention fence 70 shown in Fig. 13 comprises multiple posts 12 with one end fixed to the ground between a curved road and a sidewalk, multiple beams 14 extending horizontally between the posts, and multiple mounting structures 16, 56 for attaching the beams 14 to the posts 12. The mounting structures 16, 56 have the same configuration and differ only in the orientation when attached to the posts.

[0042] As explained above with regard to the mounting structure 56, the support member 20 can support the retaining members 18 on both sides in different positions. Thus, in the mounting structure 56 according to this embodiment, one retaining member 18 holds the beam 14 in a direction that follows the shape of the road (straight or curved), and the other retaining member 18 also holds the beam 14 in a direction that follows the shape of the road. In this way, even in a safety fence in which multiple beams 14 are connected in a line that bends along the road shape, the beams can be attached to the posts using one type of mounting structure.

[0043] (Mounting structure specifications) In the mounting structure according to each of the above-mentioned embodiments, the diameter of the cross section perpendicular to the longitudinal direction of the beam is in the range of 20 to 50 mm throughout. The diameter of the support is in the range of 20 to 50 mm, and the diameter of the beam is in the range of 20 to 50 mm. The diameter of the spherical recess 24a of the connection part 24 of the support member is in the range of 10 to 20 mm, and the diameter of the spherical protrusion 36 of the holding member 18 is in the range of 10 to 20 mm. The support member is configured to be rotatable by 0±α° (α is a predetermined value, for example, between 20° and 40°) relative to the support or bracket. The holding member is configured to be rotatable by 0±β° (β is a predetermined value, for example, between 10° and 30°) relative to the support member. The holding member is also configured to be rotatable in a combination of the horizontal and vertical directions relative to the support member.

[0044] Although the present invention has been described above with reference to the above-mentioned embodiments, the present invention is not limited to the above-mentioned embodiments, and suitable combinations or substitutions of the configurations of the embodiments are also included in the present invention. In addition, it is possible to suitably rearrange the combinations and processing order in each embodiment based on the knowledge of a person skilled in the art, and to make modifications such as various design changes to each embodiment, and such modified embodiments are also included in the scope of the present invention.
