Description

[Technical Field]

[0001] The present invention relates to a fence. [Background technology]

[0002] Conventionally, fences have been known that are constructed by erecting posts at intervals on the ground and attaching cross members at intervals in the vertical direction between the posts. However, there is a demand for improved ease of construction for such fences. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, an object of the present invention is to provide a fence that is easy to install. [Means for solving the problem]

[0004] In order to achieve the above object, the fence according to the invention described in claim 1 comprises posts, a cross member installed on the posts, and a cover material, the cross member having a stopper member at its longitudinal end, the stopper member having an engaging portion that engages with the post in a state that allows longitudinal contraction of the cross member, and the cover material is attached to the post, and the longitudinal end of the cross member is located between the post and the cover material.

[0005] The fence according to the invention described in claim 2 comprises posts, cross members attached to the visible surfaces of the posts at intervals in the vertical direction, and a cover material, the cross members having end parts at their longitudinal ends which protrude below or above the cross members, and the lower end of the end part of the lower cross member is abutted against a positioning part, and other cross members are stacked on top of that in sequence, thereby forming intervals between the cross members by the end parts, and the cover material is attached to the posts, and the longitudinal ends of the cross members are located between the posts and the cover material. [Effects of the Invention]

[0006] The fence according to claim 1 comprises posts, cross members mounted on the posts, and a cover member. The cross members have anti-slip members at their longitudinal ends, which have engaging portions that engage with the posts in a manner that allows longitudinal shrinkage of the cross members. The cover member is attached to the posts, and the longitudinal ends of the cross members are located between the posts and the cover member. Therefore, the cross members can be easily installed between the posts by engaging the engaging portions of the anti-slip members with the posts, resulting in good workability. Furthermore, the engagement of the engaging portions of the anti-slip members with the posts prevents the longitudinal ends of the cross members from slipping out from between the posts and the cover member even if the cross members are pulled by wind loads or the like. Furthermore, because the engaging portions of the anti-slip members engage with the posts in a manner that allows longitudinal shrinkage of the cross members, the cross members will not be damaged even if they shrink longitudinally due to heat.

[0007] The fence according to the invention described in claim 2 comprises posts, cross members attached to the visible surfaces of the posts at intervals in the vertical direction, and a cover material, the cross members have end parts at their longitudinal ends which protrude below or above the cross members, and the lower end of the end part of the lower cross member is abutted against the positioning part and other cross members are stacked on top of that in turn, thereby forming spaces between the cross members by the end parts, and the cover material is attached to the posts, and the longitudinal ends of the cross members are located between the posts and the cover material, so that the cross members can be placed on the visible surfaces of the posts while forming spaces between them simply by stacking the cross members in turn, resulting in good workability.

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the present invention will be described below with reference to the drawings. Figures 1 and 2 show one embodiment of a fence according to the present invention. This fence is installed at the boundary between a road and a site, and is composed of pillars 1a, 1b, ... erected at intervals on the ground, horizontal members 2, 2, ... erected at intervals in the vertical direction between the pillars 1a, 1b, ..., and a cover member 3 attached to the visible surface of the pillars 1a, 1b, ... facing the road. The horizontal member 2 is erected across the three pillars 1a, 1b, 1a.

[0010] As shown in Figure 1, the posts 1a and 1b are extruded aluminum alloy profiles formed into a hollow shape with a roughly rectangular cross section, and have a recess 8 along the longitudinal direction on the road-facing surface. Within the recess 8, hook-shaped engaging portions 9, 9 that open toward the center in the left-right direction are formed at intervals in the left-right direction. Furthermore, a groove 10 with a rectangular cross section is formed in the bottom of the recess 8 at the center in the left-right direction. Within the recess 8 below the lowest cross member 2, a positioning part 6 is attached, as shown in Figures 2 and 3.

[0011] The cross member 2 is a long, plate-like member made of resin, and as shown in Figure 1(b), end parts 4 that also serve as stoppers are attached to the site-facing surfaces of both longitudinal ends. The end parts 4 are made of extruded aluminum alloy profiles, and have an attachment part 11 that is attached to the cross member, and a hook-shaped engagement part 5 that is located away from the attachment part 11 on the site-facing side and opens toward the center of the cross member 2 in the longitudinal direction. The mounting portion 11 has a positioning piece 11a that engages with the longitudinal end face of the cross member 2, and a screw receiving groove 11b, and the end part 4 is attached to the cross member 2 by abutting the mounting portion 11 against the side of the site of the cross member 2 with the positioning piece 11a engaged with the longitudinal end face of the cross member 2 and threading a screw 12 inserted into the cross member 2 from the road side into the screw receiving groove 11b. As shown in Figure 3, the end part 4 protrudes downward from the lower edge of the cross member 2 by the length of the gap 7 between the upper and lower cross members 2. As shown in Figure 1(b), the engaging portions 5 of the end part 4 are arranged so as to overlap with the engaging portions 9 provided in the recesses 8 of the pillar 1a in a staggered orientation in the prospective direction. A gap 13 of about 5 mm is provided between the tip 9a of the engaging portion 9 of the pillar 1a and the bottom 5b of the engaging portion 5 of the end part 4, and between the tip 5a of the engaging portion 5 of the end part 4 and the bottom 9b of the engaging portion 9 of the pillar 1a.

[0012] As shown in Figure 1, a spacer 14 is attached to the road-side visible surface of pillar 1a between the upper and lower cross members 2, 2. A cover material 3 is placed on the road side of pillar 1a so as to straddle the spacer 14 and the cross members 2, 2, ..., and the cover material 3 and spacer 14 are fastened together to pillar 1a with screws 15 from the road side. As shown in Figure 1(b), the longitudinal ends of the cross members 2, 2, ... are positioned between pillar 1a and cover material 3, so that the longitudinal ends of the cross members 2, 2, ... are sandwiched between pillar 1a and cover material 3.

[0013] The longitudinal center of the cross members 2, 2, ... is fixed to the facing surface of the middle pillar 1b with a screw 16 from the road side, as shown in Figure 2. The recess 8 of the middle pillar 1b is closed by attaching a batten 17.

[0014] As explained above, this fence has end parts 4 attached to the longitudinal ends of the cross members 2, 2, ..., which also serve as anti-detachment members, and the engaging portions 5 of the end parts 4 are arranged so as to overlap in the prospective direction in alternating directions with the engaging portions 9 provided in the recesses 8 of the pillars 1a (see Figure 1(b)). When the cross member 2 is pulled by wind load or the like, the engaging portions 5 of the end parts 4 of the cross member 2 engage with the engaging portions 9 of the pillars 1a, preventing the longitudinal ends of the cross member 2 from slipping out from between the pillars 1a and the cover material 3. Furthermore, as shown in Figure 4(a), in the initial state, there is a gap 13 of approximately 5 mm between the tip 9a of the engaging portion 9 of the pillar 1a and the bottom 5b of the engaging portion 5 of the end part 4, and between the tip 5a of the engaging portion 5 of the end part 4 and the bottom 9b of the engaging portion 9 of the pillar 1a. Therefore, when the cross member 2 expands longitudinally due to heat, as shown in Figure 4(b), or when the cross member 2 contracts longitudinally, as shown in Figure 4(c), this expansion and contraction can be absorbed and tolerated.

[0015] Next, we will explain the construction procedure for this fence. First, pillars 1a, 1b, 1a, ... are erected on the ground at a specified interval. Positioning parts 6 are attached to the bottom of pillar 1a, which supports the longitudinal ends of horizontal member 2, and battens 17 are attached to intermediate pillar 1b, which supports the longitudinal center of horizontal member 2, to block recesses 8. Next, as shown in Figure 3, the cross members 2, to which end pieces 4 have been attached in advance to both longitudinal ends, are inserted one after the other from the top end of the column 1a, with the engaging parts 5 of the end pieces 4 engaging with the engaging parts 9 of the column 1a. The bottommost cross member 2 is positioned at a predetermined height with the lower end of the end piece 4 abutting against the positioning part 6, and the second and subsequent cross members 2 placed on top of it have end pieces 4 that protrude below the lower edge of the cross member 2, forming a certain gap 7 between them and the adjacent cross members 2 below. Next, spacers 14 are attached between the cross members 2 on the road-side facing surface of the pillars 1a with double-sided tape or the like. Next, the cover material 3 is placed on the road side of the pillar 1a and fixed with screws 15. Finally, the longitudinal center portions of the horizontal members 2, 2, . . . are fixed to the intermediate support 1b with screws 16.

[0016] As described above, this fence comprises pillars 1a, 1b, ..., cross members 2, 2, ... mounted on pillars 1a, 1b, ..., and cover material 3. The cross member 2 has a retaining member (end part) 4 at its longitudinal end, and the retaining member 4 has an engaging portion 5 that engages with pillar 1a in a state that allows longitudinal contraction of the cross member 2. The cover material 3 is attached to pillar 1a, and the longitudinal end of the cross member 2 is located between pillar 1a and cover material 3. Therefore, by engaging the engaging portion 5 of the retaining member 4 with pillar 1a, the cross member 2 can be easily attached between pillars 1a, 1b, and 1a, resulting in good construction efficiency. Furthermore, because the engaging portion 5 of the retaining member 4 engages with pillar 1a, the longitudinal end of the cross member 2 can be prevented from slipping out from between pillar 1a and cover material 3 even if the cross member 2 is pulled by wind load or the like. Furthermore, the engaging portion 5 of the anti-detachment member 4 engages with the pillar 1a in a state that allows the cross member 2 to shrink longitudinally, so that the cross member 2 will not be damaged even if it shrinks longitudinally due to heat. The retaining member 4 has an engaging portion 5 which engages with the pillar 1a with a margin in the left-right direction, so that it can absorb and tolerate shrinkage of the horizontal member 2 in the longitudinal direction. The anti-detachment member 4 has a screw receiving groove 11b and is attached to the cross member 2 with a screw 12 that threads into the screw receiving groove 11b. This eliminates the need to form a female screw hole in the anti-detachment member 4 and allows the member to be screwed at any position in the vertical direction, making it easy to attach the anti-detachment member 4 to the cross member 2.

[0017] This fence also comprises pillars 1a, 1b, ..., cross members 2, 2, ... attached to the visible faces of the pillars 1a, 1b, ... at intervals in the vertical direction, and a cover material 3. The cross member 2 has end parts 4 at its longitudinal ends, which protrude above or below the cross member 2. The lower end of the end part 4 of the lower cross member 2 abuts against the positioning part 6, and the other cross members 2, 2, ... are sequentially stacked on top of that, thereby forming a gap 7 between the cross members 2, 2 by the end parts 4. The cover material 3 is attached to the pillar 1a, and the longitudinal end of the cross member 2 is located between the pillar 1a and the cover material 3, so that the cross members 2, 2, ... can be positioned on the visible face of the pillar 1a simply by stacking the cross members 2, 2, ... in order, while forming the gap 7 between the cross members 2, 2, and therefore construction is easy. The end part 4 has an engaging portion 5 that engages with the column 1a so as to be slidable in the longitudinal direction, so that the cross member 2 can be easily attached by engaging the engaging portion 5 with the column 1a and dropping it successively from the upper end of the column 1a, thereby further improving workability.

[0018] The present invention is not limited to the above-described embodiments. The cross-sectional shape and material of the pillars can be changed as appropriate. The horizontal members are not limited to those made of resin, but may be made of wood, aluminum, etc. The material and cross-sectional shape of the retaining member can be changed as appropriate. The end parts may not have a portion that engages with the pillars. The end parts may also protrude above the horizontal members. [Explanation of symbols]
