Description

[Technical Field]

[0001] The present invention relates to a fence body in which multiple installation members are attached to a single support post. [Background technology]

[0002] Fences such as guardrails and walls, in which beams, panels, and other erection members are attached between spaced apart posts, have been in use for some time. While most such fences have a structure in which two erection members are fixed to both sides of the posts and arranged in a straight line in plan view, fences in which three or more erection members are fixed to one post are also used, and inventions relating to such configurations have been proposed.

[0003] For example, Patent Document 1 discloses a mounting structure for a cross beam proposed by the present applicant, in which four brackets are attached to a cylinder erected on the ground, and cross beams are arranged in four directions from the cylinder via each mounting bracket, wherein the mounting bracket has a U-shaped receiving portion at one end that supports the cross beam along the diameter of the cylinder, and a fixing plate portion at the other end that is fixed to the side wall of the cylinder, and two pairs of mounting brackets are provided, arranged opposite each other with the fixing plate portions on the inside, and one fixing plate portion is overlapped with the front surface of the other fixing plate, and each mounting bracket is attached to the cylinder by a fixing bolt that passes from the overlapping portion of one fixing plate portion through the cylinder and into the overlapping portion of the other fixing plate portion.

[0005] According to the mounting structure of the cross beam in Patent Document 1, the mounting bracket that attaches the cross beam to the cylinder has a fixing plate portion that fits along the side wall of the cylinder, and two mounting brackets with these fixing plate portions stacked on top of each other are fixed to the support with a fixing bolt, so that four mounting brackets can be attached at the same height position on one cylinder. The present invention provides a fence structure that uses a different configuration to fix a plurality of erection members such as beams at the same height on posts. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention has the following configuration. In other words, the fence body of the present invention is a fence body comprising a support post, a plurality of mounting members fixed to the side of the support post, and erection members attached to the mounting members, wherein each of the mounting members is fixed to the support post by a first male screw member and a second male screw member that pass through the support post, and the first male screw member and the second male screw member each have a notch in a shaft portion having a male screw portion, the shaft portion of the second male screw member is arranged in the notch of the first male screw member, and the shaft portion of the first male screw member is arranged in the notch of the second male screw member, and the shaft portions of the male screw members are arranged in an intersecting manner and at approximately the same position in the vertical direction.

[0007] According to the fence body of the present invention, the mounting member for attaching the erection member is attached by the first male screw member and the second male screw member that pass through the support pole, so the mounting member can be firmly attached to the support pole. Furthermore, a notch is provided in the shaft portion having the male thread portion of each of the first male thread member and the second male thread member, the shaft portion of the second male thread member is arranged in the notch of the first male thread member, and the shaft portion of the first male thread member is arranged in the notch of the second male thread member, and the shaft portions of each male thread member are arranged in a cross-shaped manner and at approximately the same position in the vertical direction.Therefore, each male thread member can be used to fix multiple mounting members in an arrangement other than a linear arrangement in a plan view, and multiple erection members can be attached to the support in such an arrangement.

[0008] Furthermore, by attaching the mounting members to both ends of either the first male screw member or the second male screw member and fixing the three mounting members to the support at approximately the same vertical position, the three erection members attached to each mounting member can be arranged in a T-shape when viewed from above, etc., which is preferable as it allows the formation of fence bodies of various shapes.

[0009] Furthermore, by attaching the mounting members to both ends of the first male screw member and the second male screw member and fixing the four mounting members to the support at approximately the same vertical position, the four erection members attached to each mounting member can be arranged in a cross shape or the like when viewed from above, which is preferable as it allows the formation of fence bodies of various shapes. [Effects of the Invention]

[0010] According to the fence of the present invention, a plurality of erection members can be attached to the support post at approximately the same position in the vertical direction by means of two male screw members that pass through the support post. [Brief explanation of the drawings]

Specifically, the mounting portion 42 has a generally semi-cylindrical upper portion 42a and a flat lower portion 42b connected to the lower side thereof, and the inner surface of the upper portion 42a is formed in a curved plate shape that fits along the outer peripheral surface of the installation member 3. The mounting member 4 is configured so that the end of the erection member 3 is stored inside the mounting portion 42, and the end of the erection member 3 is fixed as shown in Figures 1 and 2 by the bolt B, which has a male thread member inserted into each through hole 43 and the through hole 31 of the erection member 3.

[0018] FIG. 10 shows the male screw member 5, where (A) is a front view, (B) is a bottom view, and FIG. 11 is a left side view of FIG. The male threaded member 5 shown in Figures 10 and 11 has a hexagonal column-shaped head 51 and a shank 52 extending from the head 51, with a male threaded portion 52a formed on the shank 52. A notch 52b is formed in the shank 52. The notch 52b is provided so as to be formed at least near the center of the longitudinal direction of the shank 52, and as shown in Figure 10, the notch 52b is formed to have a size of at least half the total length of the shank 52 from the tip side toward the head 51 side. The cross section of the notch 52b is formed in an arch shape that is smaller than a semicircle, and the cross section of the shank 52 at the part where the notch 52b is formed is formed in an approximately semicylindrical shape that is slightly larger than a semicircle. The male thread member 5 shown in FIGS. 10 and 11 is provided by machining a hexagonal bolt, and the shaft portion 52 of the hexagonal bolt is machined to form a notch 52b.

[0019] FIG. 12 is a view showing the state before the mounting member 4 shown in FIGS. 5 to 9 is attached to the support 2A shown in FIG. The support column 2A shown in FIG. 12 is a cross-sectional view taken along the line AA in FIG. The male screw member 5A serving as the first male screw member 5A has the same shape as the male screw member 5 shown in Figures 10 and 11, with the shaft portion 52 facing left and right in the figure and the notch portion 52b positioned vertically below the shaft portion 52. The second male screw member 5B has the same shape as the male screw member 5 shown in Figures 10 and 11, with the shaft portion 52 facing vertically in the figure and the notch portion 52b positioned vertically above the shaft portion 52.

[0020] Each mounting member 4 shown in FIG. 12 is fixed to the support 2A by inserting the shaft portion 52 into the through-hole 21 and by using male screw members 5A, 5B that penetrate the support 2A. FIG. 13 is a diagram showing a state in which the mounting members 4 are fixed to the support column 2A of FIG. The two mounting members 4 arranged on the left and right sides of the support 2A in the figure are fixed to the support 2A by inserting the shaft portion 52 of the first male screw member 5A that penetrates the support 2A into the through hole 41a of each base 41, and screwing a nut N onto the male screw portion 52a of the shaft portion 52. In addition, the two mounting members 4 arranged on the vertical side of the support 2A in the figure are fixed to the support 2A by inserting the shaft portion 52 of the second male screw member 5B that penetrates the support 2A into the through hole 41a of each base 41, and screwing a nut N onto the male screw portion 52a of the shaft portion 52. As shown in FIG. 13, the first male screw member 5A and the second male screw member 5B are arranged so as to intersect with each other inside the support column 2A.

[0021] FIG. 14 is a cross-sectional view taken along the line BB in FIG. 13 and 14, the first male screw member 5A has a portion of its shank 52 disposed at a position where the notch 52b is formed in the shank 52 of the second male screw member 5B. In addition, in Fig. 14, the shanks 52 of the male screw members 5A and 5B are oriented perpendicular to the longitudinal direction. Furthermore, a part of the shaft portion 52 of the second male screw member 5B is disposed at the position where the notch portion 52b of the shaft portion 52 of the first male screw member 5A is formed. By arranging the male thread members 5A, 5B in this manner, the two intersecting male thread members 5A, 5B can be arranged at approximately the same position in the vertical direction. Arranging them at approximately the same position in the vertical direction means that the difference in their positions in the vertical direction is smaller than the nominal diameter d of the male thread portion 52a of the first male thread member 5A.

[0022] By using the method shown in FIGS. 12 and 13, four mounting members 4 can be arranged in a cross shape in plan view and fixed at approximately the same positions in the vertical direction of the support pole 2A. Furthermore, by attaching the end of the erection member 3 shown in Figure 4 to the mounting portion 42 of each mounting member 4 shown in Figures 13 and 14, it is possible to attach four erection members 3 in a cross-shaped arrangement in a plan view at approximately the same vertical position on the support 2A, as in the support 2A shown in Figures 1 and 2. In addition, in Figure 13, if the mounting member 4 on the right side of the figure is not attached to the first male screw member 5A, and the three mounting members 4 are fixed to approximately the same vertical position on the support 2 to attach the installation members 3, each installation member 3 can be arranged and installed in a T-shape in plan view, as in the support 2B shown in Figure 1. Furthermore, in Figure 13, if the mounting member 4 on the right side of the figure is not attached to the first male screw member 5A and the mounting member 4 on the lower side of the figure is not attached to the second male screw member 5B, the two mounting members 4 can be fixed at approximately the same vertical position on the support 2 and the erection members 3 can be attached, and each erection member 3 can be arranged in an L-shape when viewed from above.

[0023] The fence body 1 according to the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the present invention. For example, the fence body 1 shown in Figures 1 and 2 has erection members 3 attached to the posts 2 in the form of a pair of beams spaced apart in the vertical direction, but this is not limited to this, and the erection members may be arranged in the form of panels with vertical bars between beam-shaped members spaced apart in the vertical direction, or the erection members may be formed in other shapes.

[0024] Furthermore, as shown in Figure 13, the fence body 1 has the first male screw member 5A and the second male screw member 5B arranged perpendicular to each other in a planar view, but this is not limited to this, and the angle formed by each male screw member 5A, 5B may be arranged to a value other than 90 degrees.
