DETAILED DESCRIPTION OF THE INVENTION

[0007] Hereinafter, a fence (fence body) A according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts with the same functions, and duplicated descriptions in each drawing will be omitted as appropriate.

[0008] [Basic fence configuration] As shown in Figure 1, fence A is constructed by erecting upper cross bars (horizontal members) 2 and lower cross bars (horizontal members) 3 between multiple posts 1, and attaching multiple vertical cross bars 4 between the upper cross bars 2 and lower cross bars 3. As shown in FIG. 2, the support 1 is a hollow tube, and the ends of the upper horizontal beam 2 and the lower horizontal beam 3 are inserted into a hollow portion 10 . The upper horizontal beam 2 and the lower horizontal beam 3 are fixed in place by stopper pins 5 within the hollow portion 10 of the support 1 . The vertical crosspiece 4 is attached across an upper attachment (attachment) 6 inserted inside the upper horizontal crosspiece 2 and a lower attachment (attachment) 7 inserted inside the lower horizontal crosspiece 3. Cushioning material 8 for preventing rattle of the stopper pin 5 is attached to the ends 600, 700 of the upper and lower attachments 6 and 7, and a blocking material 9 is also attached.

[0009] [Strut configuration] As shown in Figures 2 and 3, the support 1 has a cap 12 fixed to it that covers the opening 11 at the upper end, and an upper mounting hole (horizontal member insertion hole) 13 on the side into which the upper horizontal member 2 is inserted and accommodated, and a lower mounting hole (horizontal member insertion hole) 14 into which the lower horizontal member 3 is inserted and accommodated. The upper mounting hole 13 has a horizontal edge (edge) 130 on the lower side that is a horizontal straight 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 upside down, with the upper side having a horizontal edge (edge) 140 that is a horizontal straight line, and the entire circumference excluding the horizontal edge 140 is formed into an arc shape that follows a perfect circle. A pin insertion groove 15 for supporting the stopper pin 5 is provided on the wall surface of the hollow portion 10 of the support 1, and by clamping both sides of the stopper pin 5 with this pin insertion groove 15, it is possible to support it in a vertical position. Pin insertion grooves 15 are cut out in the areas corresponding to the upper mounting holes 13 and the lower mounting holes 14 so as not to interfere with the insertion of the upper horizontal cross bar 2 and the lower horizontal cross bar 3 into the upper mounting holes 13 and the lower mounting holes 14.

[0010] [Upper horizontal bar configuration] As shown in Figure 3, the upper horizontal bar 2 has an outer peripheral shape that is similar to but slightly smaller than the shape of the upper mounting hole 13, an opening 20 on the lower side that runs along the longitudinal direction of the upper horizontal bar 2, and a retaining recess 21 on the inner periphery that is continuous with the opening 20.It is a downward-facing, approximately C-shaped member in cross section. As shown in Figures 2 and 3, when such an 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, and this clearance c can be used to fine-tune the angle of the upper horizontal bar 2.

[0011] As shown in Figs. 2 and 4(a), the upper horizontal beam 2 has a through-hole 22 at the portion where it is inserted into the support post 1, through which the stopper pin 5 passes. The through hole 22 is formed as a long hole with its longitudinal side aligned with the axis of the upper horizontal bar 2, and the angle and amount of intake of the upper horizontal bar 2 can be fine-tuned by sliding the through hole 22 around the axis of the stopper pin 5. Furthermore, the through-hole 22 being an elongated hole widens the range through which the stopper pin 5 passes, so that the operation of passing the stopper pin 5 through can be carried out easily and quickly. Such a through hole 22 allows fine adjustment of the angle and amount of engagement of the upper cross bar 2 with the stopper pin 5 passing through, and also makes it easy and quick to pass the stopper pin 5 through the through hole 22 inside the support 1.

[0012] As shown in FIG. 3, the holding recess 21 holds the upper part 6, and is provided with a contact portion 210, an engagement portion 211, and a holding portion 212. The contact portion 210 is provided above the holding recess 21, and is contacted by the upper surface of the upper attachment 6 built into the upper horizontal beam 2. The engaging portion 211 is provided below the holding recess 21, and engages with the engaged portion 60 provided on the upper attachment 6 built into the upper horizontal rail 2 by being inserted therein. The holding portion 212 holds a protruding portion 82 (described later) of the cushion material 8 so as to sandwich it from above and below, and prevents the cushion material 8 from moving in the up and down direction when the protruding portion 82 is held. Such a retaining recess 21 allows the upper surface of the inserted upper part 6 to abut against the abutting portion 210 and the engaged portion 60 of the upper part 6 to engage with the engaging portion 211, thereby holding the upper part 6 inside the upper cross bar 2. Furthermore, the holding portion 212 can prevent the cushion material 8 from moving up and down, so that the cushion material 8 can be held in a fixed position during the penetration operation of the stopper pin 5, which will be described later.

[0013] [Bottom horizontal bar configuration] As shown in Figures 2 and 3, the lower horizontal bar 3 has the same configuration as the upper horizontal bar 2 but is turned upside down.The outer shape is a similar shape to the lower mounting hole 14 but slightly smaller, and it has an opening 30 on the upper side that runs along the entire longitudinal length of the lower horizontal bar 3.It is a downward-facing, approximately C-shaped section of a molded member with a retaining recess 31 on the inner circumference that is continuous with the opening 30. As shown in Figure 3, when such a lower horizontal crosspiece 3 is inserted into the lower mounting hole 14, a clearance c is secured between the outer periphery of the lower horizontal crosspiece 3 and the edge of the lower mounting hole 14, and this clearance c can be used to fine-tune the angle of the lower horizontal crosspiece 3.

[0014] As shown in Figs. 2 and 4(b), the lower horizontal beam 3 has a through-hole 32 at the portion where it is inserted into the support post 1, through which the stopper pin 5 passes. The through hole 32 is formed as a long hole with its longitudinal side aligned with the axis of the lower horizontal bar 3, and the angle and amount of intake of the lower horizontal bar 3 can be fine-tuned by the through hole 32 sliding around the axis of the stopper pin 5. Furthermore, the through-hole 32 being an elongated hole widens the range through which the stopper pin 5 passes, so that the operation of passing the stopper pin 5 through can be carried out easily and quickly. Such a through hole 32 allows fine adjustment of the angle and amount of engagement of the upper cross bar 2 with the stopper pin 5 passing through, and also makes it easy and quick to pass the stopper pin 5 through the through hole 32 inside the support 1.

[0015] As shown in FIG. 3, the holding recess 31 holds the lower part 7, and is provided with an abutting portion 310, an engaging portion 311, and a holding portion 312. The abutment portion 310 is provided below the retaining recess 31 and is abutted by the underside of the lower attachment 7 built into the lower cross bar 3, and the engagement portion 311 is provided above the retaining recess 31 and is engaged by the engaged portion 70 provided on the lower attachment 7 built into the lower cross bar 3. The holding portion 312 holds a protruding portion 82 (described later) of the cushion material 8 so as to sandwich it from above and below, and prevents the cushion material 8 from moving in the up and down direction when the protruding portion 82 is held. Such a retaining recess 31 can hold the lower part 7 inside the lower crosspiece 3 by abutting the underside of the inserted lower part 7 against the abutment portion 310 and engaging the engaged portion 70 of the lower part 7 with the engaging portion 311. Furthermore, the holding portion 312 can prevent the cushion material 8 from moving up and down, so that the cushion material 8 can be held in a fixed position during the penetration operation of the stopper pin 5, which will be described later.

[0016] [Vertical beam configuration] As shown in Figure 1, the vertical crosspiece 4 is attached across the upper and lower crosspieces 6 and 7, with the upper end 40 inserted into the groove 610 of the upper crosspiece 6 built into the upper horizontal crosspiece 2 and pivotally supported by the upper crosspiece 6, and the lower end 41 inserted into the groove 710 of the lower crosspiece 7 built into the lower horizontal crosspiece 3 and pivotally supported by the lower crosspiece 7. The vertical beam 4 is axially supported so as to be freely rotatable relative to the upper and lower attachments 6 and 7. In other words, when the angle between the upper horizontal crosspiece 2 and the lower horizontal crosspiece 3 is fine-tuned from a horizontal state to an inclined state, the vertical crosspiece 4 rotates in response to the longitudinal deviation of the upper horizontal crosspiece 2 and the lower horizontal crosspiece 3, thereby allowing the vertical crosspiece 4 to be placed in a vertical state.

[0017] [Stopper pin configuration] As shown in Figures 2, 3, and 6(a) and (b), the stopper pin 5 is a metal rod formed into an approximately L-shape with a pointed lower end.The vertical portion 50 on the longitudinal side is inserted into the interior of the support 1 through the opening 11 at the top of the support 1 and passes through the pin insertion groove 15 and through holes 22 and 32, connecting the upper cross bar 2 and lower cross bar 3 to the support 1 and preventing them from coming loose. The horizontal portion 51 on the upper short side of the stopper pin 5 is used to rotate the stopper pin 5 around its axis and is also used to strike the stopper pin 5 with a hammer when passing it through the through holes 22 and 32 (see Figures 6(c) and (d)). As shown in Figures 2 and 3, the stopper pin 5 has, in the longitudinal region (partial region) of the vertical portion 50 located between the upper mounting hole 13 and the lower mounting hole 14, a bulging portion 52 in one direction of the shaft diameter that is larger than the width of the pin insertion groove, and a narrow portion 53 in the other direction of the shaft diameter that is equal to or smaller than the width of the pin insertion groove. As shown in FIG. 4 and FIGS. 6(c) and (d), the bulging portion 52 and the narrow width 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 narrow 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 described later, the directions of the bulging portion 52 and the narrow portion 53 can be determined by checking the orientation of the horizontal portion 51. The narrow width portion 53 in this embodiment is formed by crushing both radially opposite sides of the outer periphery of the stopper pin 5, and the bulging portion 52 is formed by the bulging of both sides perpendicular to the narrow width portion 53 in the radial direction due to the crushing force generated when forming the narrow width portion 53. In the present invention, as a means for forming the bulge portion 52, a metal piece having a shape corresponding to the bulge portion 52 may be attached to the outer surface of the vertical portion 50 of the stopper pin 5 by a fixing means such as welding (not shown). In this case, the narrow width portion 53 is the peripheral 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 placed 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 width portion 53 is smaller than the groove width of the pin insertion groove 15 , a gap s is generated between the narrow width portion 53 and the wall surface 151 . Next, as shown in FIG. 6(d), when the stopper pin 5 is rotated 90 degrees around its axis by holding the horizontal portion 51, the bulging portion 52 comes into pressure contact with the wall surface 151 of the pin insertion groove 15. That is, when the stopper pin 5 is inserted into the pin insertion groove 15, the bulge portion 52 presses against the wall surface 151 of the pin insertion groove 15, eliminating the gap s in the part facing the bulge portion 52 and allowing the stopper pin 5 to be firmly held in the pin insertion groove 15. Therefore, even if the fence A is swayed by wind or the like, the stopper pin 5 does not collide with the pin insertion groove 15, and therefore the generation of collision noise can be prevented.

[0019] [Superscript structure] As shown in FIG. 3, the upper attachment 6 is a member having a substantially U-shaped cross section that is inserted into the holding recess 21 of the upper horizontal rail 2. The upper attachment 6 is formed with a groove 610 having a downward opening 61 , and an engaged portion 60 is provided at the lower edge of the opening 61 , and a through hole 62 is formed in the upper surface of the groove 610 . The engaged portion 60 is formed in a substantially L-shape over the entire length of the upper part 6, and is engaged in an inserting manner with an engaging portion 211 recessed in the holding recess 21 when the upper part 6 is inserted. The groove 610 is a portion into which the vertical bar 4 is inserted, and is formed over the entire length of the upper attachment 6. As shown in Figures 2 and 4(a), the through hole 62 is a long hole through which the stopper pin 5 passes, and is formed in approximately the same shape as the through hole 22 of the upper horizontal bar 2, and is arranged so that they face each other in the vertical direction when the upper attachment 6 is built into the upper horizontal bar 2. As shown in FIG. 2, a drain hole 620 is provided on the upper surface of the groove 610 near the blocking member 9.

[0020] As shown in Figure 3, such an upper attachment 6 is embedded in the upper horizontal bar 2 by inserting it into the retaining recess 21 from one end side of the upper horizontal bar 2. When embedded, the upper surface of the upper attachment 6 abuts against the abutment portion 210 and the engaged portion 60 engages with the engaging portion 211, so that it is securely held in the upper horizontal bar 2 as shown in Figure 2, and the through hole 22 of the upper horizontal bar 2 and the through hole 62 are connected. Furthermore, the through-hole 62 being an elongated hole widens the range through which the stopper pin 5 passes, so that the operation of passing the stopper pin 5 through can be carried out easily and quickly. Such a through hole 62 allows fine adjustment of the angle and amount of engagement of the upper cross bar 2 with the stopper pin 5 passing through, and also makes it easy and quick to pass the stopper pin 5 through the through hole 22 inside the support 1.

[0021] [Subscript Configuration] As shown in Figures 2 and 3, the lower attachment 7 has the same configuration as the upper attachment 6 but is turned upside down, and is a member with an approximately C-shaped cross section that is inserted into the retaining recess 31 of the lower cross bar 3. The lower part 7 has a groove 710 formed therein, which has an upward opening 71 , an engaged portion 70 provided at the upper edge of the opening 71 , and a through hole 72 formed in the lower surface of the groove 710 . The engaged portion 70 is formed in a substantially L-shape over the entire length of the sub-attachment 7, and is engaged in an inserting manner with an engaging portion 311 recessed in the holding recess 31 when the sub-attachment 7 is inserted. The groove 710 is a portion into which the vertical bar 4 is inserted, and is formed so as to face the opening 61 of the upper part 6 over the entire length of the lower part 7 . As shown in Figures 2 and 4(b), the through hole 72 is a long hole through which the stopper pin 5 passes, and is formed in approximately the same shape as the through hole 32 of the lower horizontal bar 3, and is arranged so that they face each other in the vertical direction when the lower attachment 7 is built into the lower horizontal bar 3. As shown in FIG. 2, drain holes 720 are provided near the blocking material 9 on the lower surface of the groove 710 to drain rainwater flowing inside the groove 710.

[0022] As shown in Figure 3, such a lower attachment 7 is embedded in the lower cross bar 3 by inserting it into the retaining recess 31 from one end side of the lower cross bar 3. When embedded, the underside of the lower attachment 7 abuts against the abutment portion 310, and the engaged portion 70 engages with the engaging portion 311, so that the lower attachment 7 is securely held in the lower cross bar 3, and the through hole 32 of the lower cross bar 3 and the through hole 72 are connected, as shown in Figure 2. Furthermore, the through-hole 72 being an elongated hole widens the range through which the stopper pin 5 passes, so that the operation of passing the stopper pin 5 through can be carried out easily and quickly. Such a through hole 72 allows fine adjustment of the angle and amount of engagement of the lower cross bar 3 with the stopper pin 5 passing through, and also makes it easy and quick to pass the stopper pin 5 through the through hole 72 inside the support 1.

[0023] [Cushioning material composition] The cushioning material 8 is made of an elastic material such as rubber or synthetic resin, and as shown in Figures 2 to 4, is inserted into the ends 600, 700 of the upper and lower attachment parts 6 and 7, respectively. As shown in Figure 5, the cushion material 8 has an insertion portion 80 that is inserted into the end portions 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 protrusion 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 cross bar 2 and lower cross bar 3 and holds the cushion material 8 so that it does not move in the vertical direction with the holding portions 212, 312, and a through hole 83 provided in the insertion portion 80.

[0024] Here, the ends 600, 700 of the upper and lower terminals 6 and 7 refer to the area from the end faces 63, 73 of the upper and lower terminals 6 and 7 to halfway toward the end faces on the opposite longitudinal side of the upper and lower terminals 6 and 7, and are the areas where the blocking material 9 is attached. This area varies depending on the sizes of the cushion material 8 and the blocking material 9 and the attachment position of the blocking material 9.

[0025] As shown in FIG. 4, the insertion portion 80 is inserted into the ends 600, 700 of the upper and lower parts 6 and 7 with a portion of the insertion portion in close contact with the ends, and the inserted state is maintained by the elasticity of the close contact portion. As shown in Figure 5, the abutment portion 81 is integrally formed with the insertion portion 80, and as shown in Figure 4, it abuts against the edges of the end faces 63, 73 of the upper and lower attachments 6 and 7, thereby maintaining the insertion position of the insertion portion 80 correctly. The protrusions 82 are provided on both ends of the abutment portion 81, parallel to the insertion portion 80, and protrude toward the tip of the insertion portion 80 (upper attachment 6 and lower attachment 7), and are formed so that when the insertion portion 80 is inserted, they penetrate from the end faces 63, 73 of the upper attachment 6 and lower attachment 7 into between the outer surfaces 64, 74 of the upper attachment 6 and lower attachment 7 and the inner surfaces 23, 33 of the upper cross bar 2 and lower cross bar 3. As described above, the protruding portion 82 is held by the holding portions 212 and 312 so as not to move in the vertical direction when the insertion portion 80 is inserted. The through hole 83 is a long hole through which the stopper pin 5 passes, and its longitudinal length is approximately the same as that of the through hole 22 of the upper horizontal bar 2 and the through hole 32 of the lower horizontal bar 3, and it is arranged so that it faces each other in the vertical direction when the insertion portion 80 is inserted into the ends of the upper and lower horizontal bar 6 and 7. In addition, the through hole 83 is narrower than the diameter of the stopper pin 5, and when the stopper pin 5 penetrates, it is pushed out in the width direction and then returns to its original shape, thereby holding the stopper pin 5 with its elastic force, thereby preventing the stopper pin 5 from rattling.

[0026] Such cushioning material 8 can be firmly attached to the upper and lower parts 6 and 7 by the elasticity of the insertion part 80 inserted into the ends 600, 700 of the upper and lower parts 6 and 7 coming into close contact. When the insertion portion 80 is inserted, the cushion material 8 is held by the holding portions 212, 312 so that the protrusion 82 does not move in the vertical direction, so that the cushion material 8 on the upper attachment 6 side and the lower attachment 7 side can maintain its fixed position against the frictional force generated when the stopper pin 5 pushes and expands the through hole 83 as it passes through. In other words, the cushion material 8 can hold the stopper pin 5 in a fixed position when it is inserted, and can prevent it from coming off the upper and lower attachments 6 and 7, making it possible to insert the stopper pin 5 easily and quickly. Furthermore, since the stopper pin 5 is sandwiched above and below by the through holes 83 of the cushion material 8 on both the upper and lower attachment parts 6 and 7 sides, rattling of the stopper pin 5 can be reliably suppressed.

[0027] [Configuration of the blocking material] As shown in FIGS. 2 to 4, the blocking members 9 are attached to the ends 600, 700 of the upper and lower attachment parts 6 and 7 so as to face the upper and lower attachment holes 13, 14 on the outside of the support 1, respectively. As shown in Figures 2 and 3, the blocking material 9 is inserted from the openings 61, 71 into the grooves 610, 710 at the ends 600, 700 of the upper and lower attachment parts 6 and 7, which are the areas where the blocking material 9 is attached, so as to block the entire inner periphery of the ends 600, 700 at positions near the upper and lower attachment holes 13, 14, and as shown in Figure 2, the end face on the support 1 side is facing the upper and lower attachment holes 13, 14 and is close to or slightly inserted. The blocking material 9 on the upper mount 6 side is attached near the upper mounting hole 13 by bringing its lower end 90 close to the lower horizontal edge 130 of the upper mounting hole 13 and close to the lower horizontal edge 130 of the upper mounting hole 13 on the same plane as the edge of the opening 20 of the upper cross bar 2. The blocking material 9 on the lower attachment part 7 side is attached near the lower attachment hole 14 by slightly inserting the upper end 91 into the lower attachment hole 14 and bringing the end 91 flush with the edge of the opening 30 of the lower cross bar 3 and close to the upper horizontal edge 140 of the lower attachment hole 14. Here, close proximity means that the lower end 90 of the blocking material 9 is brought close to the horizontal edge 130 so that the distance between the lower end 90 of the blocking material 9 and the horizontal edge 130 on the lower side of the upper mounting hole 13 is at least large enough to prevent a finger from entering the opening 61 of the upper mount 6 on the upper mounting hole 13 side. It also means that the upper end 91 of the blocking material 9 is brought close to the horizontal edge 140 so that the distance between the upper end 91 of the blocking material 9 and the horizontal edge 140 on the upper side of the lower mounting hole 14 is at least large enough to prevent a finger from entering the opening 71 of the lower attachment 7 on the lower mounting hole 14 side. The blocking material 9 may be attached to the ends 600, 700 of the upper and lower parts 6 and 7 inside the support 1.

[0028] Such a blocking material 9, in which the blocking material 9 on the upper mount 6 side blocks the entire inner periphery of the end 600 of the upper mount 6 near the upper mounting hole 13, prevents water from entering the support 1 through the opening 61 of the upper mount 6, prevents fingers from entering the support 1 through the opening 61, and prevents fingers from coming into contact with the horizontal edge 130 of the upper mounting hole 13. In addition, the blocking material 9 on the lower attachment 7 side blocks the entire inner periphery of the end 700 of the lower attachment 7 near the lower mounting hole 14, preventing water that has seeped in through the opening 71 of the lower attachment 7 from entering the support 1, preventing fingers from entering the support through the opening 71, and preventing fingers from coming into contact with the horizontal edge 140 of the lower mounting hole 14. The blocking material 9 prevents fingers from entering the support 1 when attaching the upper cross bar 2 and the lower cross bar 3 to the support 1, thereby ensuring the safety of the work.By ensuring the safety of the work, work can be done without worrying about fingers entering the support 1, which makes the construction of the fence A more efficient.

[0029] Here, it is preferable that the upper horizontal crosspiece 2, lower horizontal crosspiece 3, vertical crosspiece 4, upper attachment piece 6, lower attachment piece 7, cushion material 8, and closing material 9 be pre-assembled in a factory to form a single unit. By using such a unit, the construction of the fence A on site can be carried out efficiently.

[0030] [Modification of cushioning material] FIG. 8 shows a cushion material 8a integrally formed with a blocking portion 84 corresponding to the blocking material 9, and FIGS. 9 to 11 show enlarged cross-sectional views of a fence A incorporating the cushion material 8a. In the following, only the upper horizontal rail 2 side will be illustrated and explained. On the side of the lower horizontal beam 3, the cushion material 8a is inserted upside down.

[0031] As shown in Figure 8, the cushion material 8a has a blocking portion 84 integrally formed at the tip side of the insertion portion 80, and as shown in Figures 9 and 11, the cushion material 8a can be inserted into the end portion 600 of the upper mount 6 from the hollow portion 10 side of the support 1, and when inserted, the blocking portion 84 is positioned so as to face the upper mounting hole 13 on the outside of the support 1. As shown in Figures 9 to 11, the blocking portion 84 is inserted into the end portion 600 of the upper mount 6, which is the area where the blocking material 9 is attached, blocking the entire inner periphery of the upper mount 6, and the end face on the support 1 side is close to or slightly inserted into the upper mounting hole 13. Furthermore, as shown in Figures 9 and 10, the blocking portion 84 is attached near the upper mounting hole 13 by aligning the lower end 840 with the edge of the opening 20 of the upper cross bar 2 and close to the lower horizontal edge 130 of the upper mounting hole 13.

[0032] Such cushion material 8a is integrally provided with a blocking portion 84 corresponding to the blocking material 9, and therefore, by attaching the cushion material 8a, it is possible to perform the functions of supporting the stopper pin 5, preventing water from entering the support 1 through the opening 61 of the upper mount 6, and preventing fingers from coming into contact with the horizontal edge 130 of the upper mounting hole 13. This improves work speed and makes the construction of Fence A more efficient.

[0033] As mentioned above, the fence A configured as described above has high construction efficiency, and in addition, it can suppress rattling of the stopper pin 5, prevent rainwater from entering, and ensure work safety.

[0034] The fence A according to an embodiment of the present invention has been described in detail above with reference to the drawings, but the specific configuration is not limited to these embodiments, and the present invention also includes design changes that do not deviate from the gist of the present invention.

[0035] Furthermore, the above-described embodiments can be combined by utilizing the techniques of each other, as long as there are no particular contradictions or problems in the purpose, configuration, etc., of the embodiments. [Explanation of symbols]
