[Modes for carrying out the invention]

[0007] Hereinafter, an embodiment of the fence (fence body) A according to the present invention will be described with reference to the drawings. In the following explanation, the same symbols in different figures indicate parts with the same function, and redundant explanations in each figure will be omitted where appropriate.

[0008] [Basic Fence Configuration] As shown in Figure 1, Fence A consists of upper horizontal rails (horizontal members) 2 and lower horizontal rails (horizontal members) 3 installed between multiple support posts 1, with multiple vertical rails 4 attached between the upper horizontal rails 2 and the lower horizontal rails 3. As shown in Figure 2, the support column 1 is a hollow tube, with the ends of the upper crossbar 2 and lower crossbar 3 embedded within the hollow section 10. The upper crossbar 2 and the lower crossbar 3 are fixed within the hollow portion 10 of the support column 1 by stopper pins 5. The vertical crossbar 4 is attached across the upper bracket 6, which is inserted inside the upper horizontal crossbar 2, and the lower bracket 7, which is inserted inside the lower horizontal crossbar 3. The ends 600 and 700 of the upper attachment 6 and lower attachment 7 are fitted with cushioning material 8 to prevent rattling of the stopper pin 5, and also with a sealing material 9.

[0009] [Structure of the support columns] As shown in Figures 2 and 3, the support column 1 has a cap 12 fixed to close the opening 11 at its upper end, and is provided with an upper mounting hole (horizontal member insertion hole) 13 on its side into which the upper horizontal member 2 is inserted and held in place, and a lower mounting hole (horizontal member insertion hole) 14 into which the lower horizontal member 3 is inserted and held in place. The upper mounting hole 13 has a horizontal edge (edge) 130 on its lower side, which is a straight horizontal line, and the entire circumference excluding the horizontal edge 130 is formed in an arc shape that follows a perfect circle. The lower mounting hole 14 has the same shape as the upper mounting hole 13, but is inverted vertically. The upper side has a horizontal edge (edge) 140 which is a straight horizontal line, and the entire circumference excluding the horizontal edge 140 is formed in an arc shape that follows a perfect circle. The wall surface of the hollow section 10 of the support column 1 is provided with a pin insertion groove 15 for supporting the stopper pin 5, and by clamping both sides of the stopper pin 5 with this pin insertion groove 15, it can be supported in a vertical position. The portions corresponding to the upper mounting hole 13 and the lower mounting hole 14 are provided with pin insertion grooves 15 so as not to prevent the insertion of the upper horizontal bar 2 and the lower horizontal bar 3 into the upper mounting hole 13 and the lower mounting hole 14.

[0010] [Structure of the upper horizontal bar] As shown in FIG. 3, the upper horizontal bar 2 has an outer peripheral shape that is a similar shape slightly smaller than the shape of the upper mounting hole 13, has an opening 20 along the longitudinal direction of the upper horizontal bar 2 on the lower side, and a holding recess 21 continuous with the opening 20 is provided on the inner periphery. It is a downward-facing member having a substantially U-shaped cross section. As shown in FIGS. 2 and 3, in the state where the upper horizontal bar 2 is inserted into the upper mounting hole 13, a clearance c is secured between the outer periphery of the upper horizontal bar 2 and the edge of the upper mounting hole 13. By using this clearance c, the angle of the upper horizontal bar 2 can be finely adjusted.

[0011] Also, as shown in FIGS. 2 and 4(a), a through hole 22 through which the stopper pin 5 penetrates is provided at a portion of the upper horizontal bar 2 that is inserted into the support column 1. The through hole 22 is formed as a long hole having a longitudinal side in the direction along the axis of the upper horizontal bar 2. By sliding the through hole 22 with the stopper pin 5 as the axis, the angle and the amount of insertion of the upper horizontal bar 2 can be finely adjusted. In addition, since the range for penetrating the stopper pin 5 is expanded by the through hole 22 formed as a long hole, the penetration operation of the stopper pin 5 can be performed easily and quickly. With such a through hole 22, the angle and the amount of insertion of the upper horizontal bar 2 can be finely adjusted in the state where the stopper pin 5 penetrates, and the penetration operation of the stopper pin 5 with respect to the through hole 22 inside the support column 1 can be performed easily and quickly.

[0012] As shown in FIG. 3, the holding recess 21 holds the upper fitting 6, and a contact portion 210, an engaging portion 211, and a holding portion 212 are provided. The contact portion 210 is provided above the holding recess 21, and the upper surface of the upper fitting 6 incorporated in the upper horizontal bar 2 abuts thereon. The engaging portion 211 is located below the retaining recess 21, and engages with the engaged portion 60 provided on the upper attachment 6 which is built into the upper crossbar 2 by being inserted into it. The holding portion 212 holds the protruding portion 82 of the cushioning material 8, which will be described later, by sandwiching it from above and below, and prevents the cushioning material 8 from moving in the vertical direction while the protruding portion 82 is being held. Such a retaining recess 21 allows the upper attachment 6 to be held inside the upper crossbar 2 by bringing the upper surface of the inserted upper attachment 6 into contact with the contact portion 210 and engaging the engaged portion 60 of the upper attachment 6 with the engaging portion 211. Furthermore, the holding portion 212 prevents the cushioning material 8 from moving vertically, so the cushioning material 8 can be held in place during the insertion of the stopper pin 5, which will be described later.

[0013] [Structure of the lower crossbar] As shown in Figures 2 and 3, the lower crossbar 3 has the same configuration as the upper crossbar 2 but is inverted vertically. Its outer circumference is similar to the shape of the lower mounting hole 14, but slightly smaller. It has an opening 30 on the upper side that runs along the entire length of the lower crossbar 3, and a retaining recess 31 on the inner circumference that is continuous with the opening 30. It is a downward-facing, roughly U-shaped profile. As shown in Figure 3, when the lower crossbar 3 is inserted into the lower mounting hole 14, a clearance c is secured between the outer circumference of the lower crossbar 3 and the edge of the lower mounting hole 14. This clearance c can be used to finely adjust the angle of the lower crossbar 3.

[0014] Furthermore, as shown in Figures 2 and 4(b), the portion of the lower crossbar 3 that is inserted into the support column 1 is provided with a through hole 32 through which the stopper pin 5 passes. The through-hole 32 is formed as an elongated hole with its longitudinal side aligned with the axis of the lower crossbar 3. By sliding the through-hole 32 around the stopper pin 5, the angle and engagement amount of the lower crossbar 3 can be finely adjusted. Furthermore, the elongated through-hole 32 expands the range through which the stopper pin 5 can pass, making the insertion of the stopper pin 5 easier and quicker. Such through-holes 32 allow for fine adjustment of the angle and engagement depth of the upper crossbar 2 while the stopper pin 5 is inserted through them, and also facilitate the easy and quick insertion of the stopper pin 5 through the through-holes 32 inside the support column 1.

[0015] As shown in Figure 3, the retaining recess 31 holds the lower attachment 7 and is provided with a contact portion 310, an engaging portion 311, and a retaining portion 312. The contact portion 310 is located below the retaining recess 31 and contacts the lower surface of the lower attachment 7 which is built into the lower crossbar 3, while the engaging portion 311 is located above the retaining recess 31 and engages with the engaged portion 70 provided on the lower attachment 7 which is built into the lower crossbar 3. The holding portion 312 holds the protruding portion 82 of the cushioning material 8, which will be described later, by sandwiching it from above and below, and prevents the cushioning material 8 from moving in the vertical direction while the protruding portion 82 is being held. Such a retaining recess 31 allows the lower attachment 7 to be held inside the lower crossbar 3 by bringing the lower surface of the inserted lower attachment 7 into contact with the contact portion 310 and engaging the engaged portion 70 of the lower attachment 7 with the engaging portion 311. Furthermore, the holding portion 312 prevents the cushioning material 8 from moving vertically, so the cushioning material 8 can be held in place during the insertion of the stopper pin 5, which will be described later.

[0016] [Vertical rib configuration] As shown in Figure 1, the vertical bar 4 is attached across the upper bracket 6 and the lower bracket 7. The upper end 40 is inserted into the groove 610 of the upper bracket 6, which is built into the upper horizontal bar 2, and is pivotally supported by the upper bracket 6. The lower end 41 is inserted into the groove 710 of the lower bracket 7, which is built into the lower horizontal bar 3, and is pivotally supported by the lower bracket 7. The vertical bar 4 is pivotally supported by the upper bracket 6 and the lower bracket 7 so as to be able to rotate freely. In other words, when making fine adjustments to the angle between the upper horizontal bar 2 and the lower horizontal bar 3 from a horizontal to an inclined state, the vertical bar 4 rotates in response to the longitudinal displacement of the upper horizontal bar 2 and the lower horizontal bar 3, thereby allowing the vertical bar 4 to be set to a vertical position.

[0017] [Stopper pin configuration] As shown in Figures 2, 3, and 6(a)(b), the stopper pin 5 is a metal rod with a pointed lower end and is formed in a roughly L-shape. The vertical part 50 on the longitudinal side is inserted into the interior of the support column 1 through the opening 11 at the top of the support column 1 and passes through the pin insertion groove 15 and through holes 22 and 32, thereby connecting the upper crossbar 2 and the lower crossbar 3 to the support column 1 and preventing them from coming loose. The horizontal portion 51 on the shorter side of the upper end of the stopper pin 5 is used to rotate the stopper pin 5 on its axis, and also to strike it with a hammer when inserting the stopper pin 5 through the through holes 22 and 32 (see Figures 6(c) and 6(d)). As shown in Figures 2 and 3, the stopper pin 5 has a vertical portion 50 located between the upper mounting hole 13 and the lower mounting hole 14, and in a longitudinal region (partial region), there is a bulging portion 52 in one direction of the shaft diameter that is wider than the width of the pin insertion groove, and a narrow portion 53 in the other direction of the shaft diameter that is less than or equal to the width of the pin insertion groove. As shown in Figures 4 and 6(c)(d), the bulging portion 52 and the narrow portion 53 are arranged on both sides of the vertical portion 50 at an angle (90 degrees) perpendicular to each other in the radial direction. The bulging portion 52 is formed on the radial side of the horizontal portion 51, and the narrowing portion 53 is formed on the axial side of the horizontal portion 51. When inserting the stopper pin 5 into the pin insertion groove 15, which will be described later, the orientation of the horizontal portion 51 allows the orientation of the bulging portion 52 and the narrowing portion 53 to be determined. In this embodiment, the narrow portion 53 is formed by crushing both radially opposing sides of the outer circumference of the stopper pin 5, and the bulging portion 52 is formed by the crushing force generated when forming the narrow portion 53, causing both sides perpendicular to the narrow portion 53 in the radial direction to bulge. In the present invention, as a means of forming the bulge 52, a metal piece corresponding to the shape of the bulge 52 may be attached to the outer surface of the vertical portion 50 of the stopper pin 5 by fixing means such as welding (not shown). In this case, the narrow portion 53 is the circumferential surface of the vertical portion 50 of the stopper pin 5, excluding the bulging portion 52 (not shown).

[0018] When inserting such a stopper pin 5 into the pin insertion groove 15, first, as shown in Figure 6(c), the bulging portion 52 is positioned facing the opening of the pin insertion groove 15, and the narrow portion 53 is inserted so that it faces the wall surface 151 of the pin insertion groove 15. At this time, since the narrow portion 53 is smaller than the groove width of the pin insertion groove 15, a gap s is created between the narrow portion 53 and the wall surface 151. Next, as shown in Figure 6(d), when the stopper pin 5 is rotated 90 degrees by holding the horizontal part 51, the bulging part 52 comes into contact with the wall surface 151 of the pin insertion groove 15 in a pressure-contact manner. In other words, when the stopper pin 5 is inserted into the pin insertion groove 15, the bulging portion 52 presses against the wall surface 151 of the pin insertion groove 15, eliminating the gap s between the bulging portion 52 and the portion facing it, and the stopper pin 5 is firmly held in the pin insertion groove 15. Therefore, even if fence A sways due to wind or other factors, there is no collision between the stopper pin 5 and the pin insertion groove 15. Na Therefore, it is possible to prevent the generation of collision noise.

[0019] [Structure of the upper attachment] As shown in Figure 3, the upper attachment 6 is a member with a roughly U-shaped cross-section that is inserted into the retaining recess 21 of the upper horizontal bar 2. The upper attachment 6 has a groove 610 with a downward-facing opening 61, an engaging portion 60 is provided at the lower end edge of the opening 61, and a through hole 62 is formed on the upper surface of the groove 610. The engaged portion 60 is formed in a substantially L-shape along the entire length of the upper attachment 6, and when the upper attachment 6 is inserted, it engages with the engaged portion 211 recessed in the retaining recess 21. The groove 610 is the portion into which the vertical bar 4 is inserted, and is formed along the entire length of the upper bracket 6. As shown in Figures 2 and 4(a), the through-hole 62 is an elongated hole through which the stopper pin 5 passes. It is formed to be approximately the same shape as the through-hole 22 of the upper crossbar 2, and the upper attachment 6 is built into the upper crossbar 2 and is positioned to face the upper attachment in the vertical direction. Furthermore, as shown in Figure 2, drainage holes 620 are provided near the sealing material 9 on the upper surface of the groove 610.

[0020] As shown in Figure 3, the upper attachment 6 is inserted into the retaining recess 21 from one end of the upper crossbar 2, thereby being built into the upper crossbar 2. In this built-in state, the upper surface of the upper attachment 6 contacts the contact portion 210, and the engaged portion 60 engages with the engaging portion 211, so that it is securely held in the upper crossbar 2, as shown in Figure 2, and the through holes 22 and 62 of the upper crossbar 2 are in communication. Furthermore, the elongated through-hole 62 expands the range through which the stopper pin 5 can pass, making the insertion of the stopper pin 5 easier and quicker. Such through-holes 62 allow for fine adjustment of the angle and engagement depth of the upper crossbar 2 while the stopper pin 5 is inserted through them, and also facilitate the easy and quick insertion of the stopper pin 5 through the through-holes 22 inside the support column 1.

[0021] [Composition of the lower attachment] As shown in Figures 2 and 3, the lower attachment 7 has the same configuration as the upper attachment 6 but is inverted vertically, and is a roughly U-shaped member that is inserted into the retaining recess 31 of the lower crossbar 3. The lower attachment 7 has a groove 710 with an upward-facing opening 71, an engaging portion 70 is provided at the upper edge of the opening 71, and a through hole 72 is formed on the lower surface of the groove 710. The engaged portion 70 is formed in a substantially L-shape along the entire length of the lower attachment 7, and when the lower attachment 7 is inserted, it engages with the engaged portion 311 recessed in the retaining recess 31. The groove 710 is the portion into which the vertical bar 4 is inserted, and is formed to face the opening 61 of the upper bracket 6 along the entire length of the lower bracket 7. As shown in Figures 2 and 4(b), the through-hole 72 is an elongated hole through which the stopper pin 5 passes. It is formed to be approximately the same shape as the through-hole 32 of the lower crossbar 3, and the lower attachment 7 is built into the lower crossbar 3 and is positioned to face it in the vertical direction. Furthermore, as shown in Figure 2, drainage holes 720 are provided near the sealing material 9 on the lower surface of the groove 710 to drain rainwater flowing through the groove 710.

[0022] As shown in Figure 3, such a lower attachment 7 is inserted into the retaining recess 31 from one end of the lower crossbar 3, thereby being built into the lower crossbar 3. In this built-in state, the lower surface of the lower attachment 7 contacts the contact portion 310, and the engaged portion 70 engages with the engaging portion 311, so that it is securely held in the lower crossbar 3 as shown in Figure 2, and the through holes 32 and 72 of the lower crossbar 3 are in communication. Furthermore, the elongated through-hole 72 expands the range through which the stopper pin 5 can pass, making the insertion of the stopper pin 5 easier and quicker. Such through-holes 72 allow for fine adjustment of the angle and engagement depth of the lower crossbar 3 while the stopper pin 5 is inserted through them, and also facilitate the easy and quick insertion of the stopper pin 5 through the through-holes 72 inside the support column 1.

[0023] [Composition of cushioning material] The cushioning material 8 is made from an elastic material such as rubber or synthetic resin, and is inserted into the ends 600 and 700 of the upper attachment 6 and lower attachment 7, respectively, as shown in Figures 2 to 4. As shown in Figure 5, the cushioning material 8 has an insertion portion 80 that is inserted into the ends 600, 700 from the end faces 63, 73 of the upper and lower attachments 6 and 7, a contact portion 81 that abuts against the edges of the end faces 63, 73 of the upper and lower attachments 6 and 7, a protruding portion 82 that fits between the outer surfaces 64, 74 of the upper and lower attachments 6 and 7 and the inner surfaces 23, 33 of the upper and lower crossbars 2 and 3, and holds the cushioning material 8 in place by the holding portions 212, 312 so that it does not move in the vertical direction, and a through hole 83 provided in the insertion portion 80.

[0024] Here, the ends 600 and 700 of the upper attachment 6 and the lower attachment 7 refer to the region from the end faces 63 and 73 of the upper attachment 6 and the lower attachment 7 to the middle of the region toward the end face on the opposite side in the longitudinal direction of the upper attachment 6 and the lower attachment 7, and which is the region to which the closing material 9 is attached. This area varies depending on the size of the cushioning material 8 and the occluding material 9, as well as the mounting position of the occluding material 9.

[0025] As shown in Figure 4, the insertion portion 80 is inserted in a state in close contact with the ends 600 and 700 of the upper attachment 6 and lower attachment 7, and the inserted state is maintained by the elasticity of the contacted portion. As shown in Figure 5, the contact portion 81 is integrally formed with the insertion portion 80, and as shown in Figure 4, it contacts the edges of the end faces 63 and 73 of the upper attachment 6 and the lower attachment 7, thereby maintaining the insertion position of the insertion portion 80 correctly. The protruding portions 82 are provided at both ends of the contact portion 81, parallel to the insertion portion 80, and project toward the tip side (upper attachment 6 and lower attachment 7) of the insertion portion 80. When the insertion portion 80 is inserted, the protruding portions 82 are formed to fit between the outer surfaces 64 and 74 of the upper attachment 6 and lower attachment 7 and the inner surfaces 23 and 33 of the upper crossbar 2 and lower crossbar 3, respectively, from the end faces 63 and 73 of the upper attachment 6 and lower attachment 7. Furthermore, as mentioned above, the protruding portion 82 is held in place by the holding portions 212 and 312 so as not to move vertically when the insertion portion 80 is inserted. The through-hole 83 is an elongated hole through which the stopper pin 5 passes, and its longitudinal direction is approximately the same length as the through-hole 22 of the upper crossbar 2 and the through-hole 32 of the lower crossbar 3, and the insertion portion 80 is inserted into the ends of the upper attachment 6 and the lower attachment 7 so that they face each other in the vertical direction. Furthermore, the through-hole 83 is narrower in width than the diameter of the stopper pin 5, and the elastic force that expands the through-hole 83 in the width direction when the stopper pin 5 passes through and then returns to its original shape grips the stopper pin 5, thereby suppressing rattling of the stopper pin 5.

[0026] Such cushioning material 8 can be securely attached to the upper attachment 6 and lower attachment 7 by the elasticity of the insertion portion 80 inserted into the ends 600 and 700 of the upper attachment 6 and lower attachment 7, which then tightly adhere to them. In the insertion state of the insertion portion 80, the cushioning material 8 is held in place by the holding portions 212 and 312 so that the protruding portion 82 does not move vertically. Therefore, the cushioning material 8 on the upper attachment 6 side and the lower attachment 7 side can maintain its fixed position against the frictional force when the stopper pin 5 penetrates the through hole 83 while expanding it. In other words, the cushioning material 8 can maintain its position when the stopper pin 5 is inserted, and can also prevent it from coming loose from the upper attachment 6 and the lower attachment 7, thereby making the insertion of the stopper pin 5 easy and quick. Furthermore, since the stopper pin 5 is held between the upper and lower parts by the through-holes 83 in the cushioning material 8 on both the upper attachment 6 side and the lower attachment 7 side, rattling of the stopper pin 5 can be reliably suppressed.

[0027] [Composition of the occlusion material] As shown in Figures 2 to 4, the blocking material 9 is attached to the ends 600 and 700 of the upper attachment 6 and lower attachment 7, respectively, so as to face the upper mounting hole 13 and lower mounting hole 14 on the outside of the support column 1. As shown in Figures 2 and 3, the sealing material 9 is inserted into the grooves 610 and 710 from the openings 61 and 71 to seal the entire area around the inner perimeter of the ends 600 and 700 of the upper and lower attachments 6 and 700, which are the areas to which the sealing material 9 is attached, at a position near the upper and lower mounting holes 13 and 14. As shown in Figure 2, the end face on the support column 1 side is positioned close to or slightly inserted in front of the upper and lower mounting holes 13 and 14. The closing member 9 on the upper attachment 6 side is attached near the upper mounting hole 13 by positioning its lower end 90 close to the lower horizontal edge 130 of the upper mounting hole 13, and by positioning it flush with the edge of the opening 20 of the upper crossbar 2 and close to the lower horizontal edge 130 of the upper mounting hole 13. The closing member 9 on the lower attachment 7 side is attached near the lower mounting hole 14 by slightly inserting its upper end 91 into the lower mounting hole 14 and bringing its end 91 flush with the edge of the opening 30 of the lower crossbar 3 and close to the upper horizontal edge 140 of the lower mounting hole 14. Here, proximity means bringing the lower end 90 of the sealing material 9 closer to the horizontal edge 130 of the upper mounting hole 13 so that the distance between the lower end 90 of the sealing material 9 and the lower horizontal edge 130 of the upper mounting hole 13 is at least such that a finger cannot enter the opening 61 of the upper attachment 6 on the upper mounting hole 13 side. Furthermore, this means that the upper end 91 of the sealing material 9 should be brought closer to the horizontal edge 140 so that the gap between the upper end 91 of the sealing material 9 and the upper horizontal edge 140 of the lower mounting hole 14 is at least such that a finger cannot fit into the opening 71 of the lower attachment 7 on the lower mounting hole 14 side. The blocking material 9 may also be attached to the ends 600 and 700 of the upper attachment 6 and lower attachment 7 on the inside of the support column 1.

[0028] In this type of sealing material 9, the sealing material 9 on the upper attachment 6 side seals the entire area around the inner edge 600 of the upper attachment 6 near the upper mounting hole 13, thereby preventing water from entering the support column 1 through the opening 61 of the upper attachment 6, preventing fingers from entering the support column 1 through the opening 61, and preventing fingers from coming into contact with the horizontal edge 130 of the upper mounting hole 13. Furthermore, since the sealing material 9 on the lower attachment 7 side seals the entire area around the inner side of the end portion 700 of the lower attachment 7 near the lower mounting hole 14, it is possible to prevent water that has entered the inside of the support column 1 through the opening 71 of the lower attachment 7, prevent fingers from entering the support column through the opening 71, and prevent fingers from coming into contact with the horizontal edge portion 140 of the lower mounting hole 14. The blocking material 9 prevents fingers from entering the support post 1, ensuring safety during the installation of the upper horizontal rail 2 and lower horizontal rail 3 to the support post 1. This ensures safety during the work, allowing workers to perform the installation without worrying about fingers entering the support post 1, thus improving the efficiency of fence A construction.

[0029] In this case, it is preferable that the aforementioned upper crossbar 2, lower crossbar 3, vertical bar 4, upper bracket 6, lower bracket 7, cushioning material 8, and closing material 9 are assembled in advance at the factory to form a single unit. By using this type of unit, the construction of Fence A on site can be carried out efficiently.

[0030] [Examples of cushioning materials] Figure 8 shows a cushion material 8a with an integrally formed closing section 84 corresponding to the closing material 9, and Figures 9 to 11 show enlarged cross-sectional views of fence A with the cushion material 8a implemented. In the following explanation, only the upper horizontal bar 2 side will be illustrated. On the lower crossbar 3 side, the cushioning material 8a is inserted upside down.

[0031] As shown in Figure 8, the cushioning material 8a has a closing portion 84 integrally formed on the tip side of the insertion portion 80. As shown in Figures 9 and 11, the cushioning material 8a can be inserted into the end portion 600 of the upper attachment 6 from the hollow portion 10 side of the support column 1, and when inserted, the closing portion 84 is positioned on the outside of the support column 1 facing the upper mounting hole 13. As shown in Figures 9 to 11, the closing portion 84 is inserted into the end portion 600 of the upper attachment 6, which is the area to which the closing material 9 is attached, so as to block the entire area around the inside of the upper attachment 6, with the end face on the support column 1 side being close to or slightly inserted into the upper mounting hole 13. Furthermore, as shown in Figures 9 and 10, the closing portion 84 is mounted near the upper mounting hole 13 by having its lower end 840 flush with the edge of the opening 20 of the upper crossbar 2 and close to the lower horizontal edge 130 of the upper mounting hole 13.

[0032] Since this cushioning material 8a is integrally equipped with a closing portion 84 corresponding to the closing material 9, by attaching the cushioning material 8a, it is possible to provide support for the stopper pin 5, prevent water from entering the support column 1 through the opening 61 of the upper attachment 6, and prevent fingers from coming into contact with the horizontal edge 130 of the upper mounting hole 13. Therefore, the speed of work is improved, and the construction of fence A can be made more efficient.

[0033] As mentioned above, Fence A, with the above configuration, offers high construction efficiency, while also suppressing rattling of the stopper pin 5, preventing rainwater intrusion, and ensuring safety during work.

[0034] Although the fence A according to the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes, etc., that do not depart from the spirit of the present invention are also included.

[0035] Furthermore, the aforementioned embodiments can be combined by utilizing each other's technologies, as long as there are no particular contradictions or problems in their purpose, configuration, etc. [Explanation of Symbols]
