[Modes for carrying out the invention]

[0011] The embodiments of the present invention will now be described based on the drawings. Figures 1 to 4 show one embodiment of the structure of the present invention. This structure is applied to a fence installed at the boundary between a road and a property, and as shown in Figures 1 and 4, it comprises a plurality of support posts 11, 11, ... erected from the ground at intervals in the left-right direction, and horizontally elongated rectangular panel bodies 12, 12 positioned on the road side of the support posts 11, 11, ....

[0012] As shown in Figures 1 to 3, the panel body 12 is constructed by installing vertical rails 13 and 14 at the longitudinal ends and intermediate sections between the upper rail (profile) 1 and the lower rail (profile) 2, and attaching horizontal louver members 15 to the road sides of the vertical rails 13 and 14 at a predetermined pitch in the vertical direction. The upper rail 1, lower rail 2, vertical rails 13 and 14, and horizontal louver members 15 are made of aluminum profiles. As shown in Figure 2, the upper rail 1 has an attachment 3 mounted on its lower surface so as to be slidable in the longitudinal direction, and the upper ends of the vertical rails 13 and 14 are attached to the attachment 3 with vertical rail mounting screws 17 that are screwed into tapping holes 16 (see Figure 3). The lower ends of the vertical rails 13 and 14 are attached to the upper wall 2b of the lower rail 2 with vertical rail mounting screws 17 that are screwed into tapping holes 16. As shown in Figure 3, the vertical battens 13 and 14 have a groove 18 running lengthwise, which is open on the site side. Horizontal louver material 15 is attached to the site side of the vertical battens 13 and 14 with screws 19 inserted through the bottom wall of the groove 18 from the site side, and the groove 18 is closed by attaching a cover plate 20.

[0013] As shown in Figures 3 and 4, the panel bodies 12 are arranged in a row in the left-right direction by connecting the upper rails 1 and lower rails 2 with connecting pieces 21. As shown in Figures 2 and 4, the panel bodies 12 are fixed to the support columns 11 by the support fittings 22 attached to the lower part of the support columns 11 supporting the lower rails 2 and the retaining fittings 23 attached to the upper end of the support columns 11 holding down the upper rails 1. The support columns 11 are so-called free-standing columns whose installation position can be shifted in the left-right direction.

[0014] As shown in Figures 1-4, end caps 4 are attached to the longitudinal ends of the upper rail 1 and lower rail 2, covering the ends of the upper rail 1 and lower rail 2. The end caps 4 also serve as jigs for drilling holes in the upper rail 1, lower rail 2 and attachment 3, as will be described later. The end cap 4 is made of hard resin and, as shown in Figures 4 and 5, has a plate portion 24 that abuts against the ends of the upper rail 1 and lower rail 2, and an insertion portion 5 that is inserted into the hollow portion of the upper rail 1 and lower rail 2. As shown in Figure 5, the plate section 24 has folded-over sections 9 on the road side and the site side. The insertion section 5 is formed in a roughly U-shape with the first visible wall 6, the second visible wall 7, and the interior wall 8. As shown in Fig. 5(c), on the prospective wall 8, a first hole position indicating portion 10a and a second hole position indicating portion 10b are each formed in a square hole shape, and markings 32 corresponding to the numbers (1, 2) of the hole position indicating portions are provided at positions adjacent to the respective hole position indicating portions 10a, 10b. A notch 25 is provided in an L shape at a position adjacent to the first finding wall 6 on the front end side of the prospective wall 8. On the first finding wall 6, a third hole position indicating portion 10c is formed in a square hole shape on the front end side. The front end 6a of the first finding wall 6 extends to the same position as the front end 8a of the prospective wall 8. The second finding wall 7 is shorter than the first finding wall 6, and the front end 7a of the second finding wall 7 extends to the position of the notch 25 of the prospective wall 8. Lower holes 27 into which small-mouth cap mounting screws 26 (see Fig. 6) are screwed are formed in the first and second finding walls 6, 7.

[0015] As shown in Fig. 6(a), the small-mouth cap 4 is inserted into the hollow portion of the upper rail 1 with the insertion portion 5 in a direction such that the first finding wall 6 faces the road side and the second finding wall 7 faces the site side, and the small-mouth cap mounting screw 26 inserted into the small-mouth cap mounting hole 28 formed in the site side wall 1a of the upper rail 1 is screwed into the lower hole 27 formed in the second finding wall 7, thereby attaching it to the end portion of the upper rail 1. As shown in Fig. 6(b), the small-mouth cap 4 is attached to the longitudinal end portion of the lower rail 2 in a direction opposite to that of the upper rail 1. That is, the insertion portion 5 is inserted into the hollow portion of the lower rail 2 in a direction such that the second finding wall 7 faces the road side and the first finding wall 6 faces the site side, and the small-mouth cap mounting screw 26 inserted into the small-mouth cap mounting hole 28 formed in the site side wall 2a of the lower rail 2 is screwed into the lower hole 27 formed in the first finding wall 6 for attachment.

[0016] The panel body 12 is assembled at the factory in a fixed length (for example, 2 meters) and transported to the site where the fence is to be constructed. At the site, depending on the site conditions, as shown in Fig. 7, a left or right portion of the panel body 12 is cut to shorten the panel body 12 to the required length for use. When cutting and shortening in this manner, it is necessary to machine end cap mounting holes 28 (see Figure 6) at the cut ends of the upper rail 1 and lower rail 2, vertical rail mounting holes 29 (see Figure 2) at the cut ends of the attachment 3 and lower rail 2, and vertical rail mounting screw holes 30 (see Figure 2) at the cut end of the lower rail 2. The end cap 4 is used as a jig when machining these holes.

[0017] Figure 8-1 shows the state in which the end cap 4 is in contact with the upper rail 1 when machining the end cap mounting hole 28 in the upper rail 1. At this time, as shown by the arrow in Figure 8-1(a), the end cap 4 is slid outward, and the second visible wall 7 is brought into contact with the lower edge 1b of the upper rail 1, and the folded portion 9 is brought into contact with the end cap 1c of the upper rail 1 (the second visible wall 7 and the folded portion 9 correspond to the "positioning portion"), and the recessed wall 8 is brought into contact with the site side wall 1a of the upper rail 1, and a mark 31 is made on the upper rail 1 with a scribing needle or the like using the first hole position indicator portion 10a as a guide. After that, the end cap 4 is removed from the upper rail 1, and the end cap mounting hole 28 is machined at the position where the mark 31 was made.

[0018] Figure 8-2 shows the state in which the end cap 4 is in contact with the bottom rail 2 when machining the end cap mounting hole 28 in the bottom rail 2. At this time, the end cap 4 is positioned by bringing the second visible wall 7 into contact with the lower edge 2c of the bottom rail 2 and the folded portion 9 into contact with the end cap 2d of the bottom rail 2 (the second visible wall 7 and the folded portion 9 correspond to the "positioning portion"), bringing the visible wall 8 into contact with the site side wall 2a of the bottom rail 2, and marking 31 on the bottom rail 2 with a scribing needle or the like using the first hole position indicator portion 10a as a guide. After that, the end cap 4 is removed from the bottom rail 2, and the end cap mounting hole 28 is machined at the position where the mark 31 was made.

[0019] Figure 8-3 shows the end cap 4 in contact with the attachment 3 when machining the vertical rail mounting hole 29 in the attachment 3 below the upper rail 1. At this time, as shown by the arrow in Figure 8-3(a), the upper rail 1 is slid inward, and the end cap 4 is positioned by bringing the vertical edge 25a of the notch 25 of the recessed wall 8 into contact with the side edge 3a of the attachment 3, and the horizontal edge 25b of the notch 25 of the recessed wall 8 and the tip 7a of the second visible wall 7 into contact with the end cap 3b of the attachment 3 (the vertical edge 25a and horizontal edge 25b of the notch 25 and the tip 7a of the second visible wall 7 correspond to the "positioning part"), bringing the recessed wall 8 into contact with the upper surface 3c of the attachment 3, and marking the attachment 31 with a scribing needle or the like using the second hole position indicator part 10b as a guide. After that, the end cap 4 is separated from the attachment 3, and the mounting holes 29 for the vertical support are machined at the positions marked with the 31.

[0020] Figure 8-4 shows the end cap 4 in contact with the bottom rail 2 when machining the vertical rail mounting screw holes 30 in the lower wall 2e of the bottom rail 2. At this time, the end cap 4 is positioned by bringing the first visible wall 6 into contact with the site side wall 2a of the bottom rail 2, and the horizontal edge 25b of the notch 25 of the interior wall 8 and the tip 7a of the second visible wall 7 into contact with the end cap 2d of the bottom rail 2 (the first visible wall 6, the horizontal edge 25b of the notch 25, and the tip 7a of the second visible wall 7 correspond to the "positioning part"), bringing the interior wall 8 into contact with the lower wall 2e of the bottom rail 2, and marking the bottom rail 2 with a scribing needle or the like using the second hole position indicator part 10b as a guide. After that, the end cap 4 is removed from the bottom rail 2, and the vertical rail mounting screw holes 30 are machined at the position where the mark 31 was made.

[0021] Figure 8-5 shows the end cap 4 in contact with the bottom rail 2 when machining the vertical rail mounting hole 29 in the upper wall 2b of the bottom rail 2. At this time, the end cap 4 is positioned by bringing the horizontal edge 25b of the notch 25 of the front wall 8 into contact with the end cap 2d of the bottom rail 2, and the upper edge 6b of the first front wall 6 into contact with the projection 2f of the bottom rail 2 (the horizontal edge 25b of the notch 25 and the upper edge 6b of the first front wall 6 correspond to the "positioning part"). The first front wall 6 is then brought into contact with the upper wall 2b of the bottom rail 2, and a mark 31 is made on the bottom rail 2 using a scribing needle or the like, using the third hole position indicator 10c as a guide. After that, the end cap 4 is removed from the bottom rail 2, and the vertical rail mounting hole 29 is machined at the position where the mark 31 was made.

[0022] Figure 8-6 shows the state in which the end cap 4 is placed against the lower rail 2 when a hole is machined in the upper wall 2b of the lower rail 2, separate from the vertical rail mounting hole 29 mentioned above. At this time, the end cap 4 is positioned by bringing the vertical edge 25a of the notch 25 of the front wall 8 into contact with the projection 2f of the lower rail 2, and the horizontal edge 25b of the notch 25 of the front wall 8 and the tip 7a of the second front wall 7 into contact with the end cap 2d of the lower rail 2 (the vertical edge 25a and horizontal edge 25b of the notch 25 and the tip 7a of the second front wall 7 correspond to the "positioning part"), and the front wall 8 is brought into contact with the upper wall 2b of the lower rail 2, and a mark 31 is made on the lower rail 2 with a scribing needle or the like using the second hole position indicator part 10b as a guide. After that, the end cap 4 is removed from the lower rail 2, and a hole is machined at the position where the mark 31 was made.

[0023] Thus, this structure is easy to use because, when the panel body 12 is cut down, the necessary holes are made at the cut ends of the upper rail 1, lower rail 2, and attachment 3 by using the end caps 4 attached to the upper rail 1 and lower rail 2 as jigs.

[0024] After cutting and shortening the panel body 12, holes are drilled in the upper rail 1, lower rail 2, and attachment 3 as described above. Then, the vertical rail 13 is attached between the upper rail 1 and lower rail 2 with vertical rail mounting screws 17, the ends of the horizontal louvers 15 are screwed to the vertical rail 13 from the site side, and end caps 4 are attached to the ends of the upper rail 1 and lower rail 2 and secured with end cap mounting screws 26.

[0025] As described above, this structure comprises a profile (attachment 3, bottom rail 2) and end caps 4 attached to the longitudinal ends of the profile 3 and 2. The end cap 4 also serves as a jig for drilling holes in the profile 3 and 2. It has positioning parts (vertical edges 25a and horizontal edges 25b of the notch 25, tip 7a of the second visible wall 7, and first visible wall 6) for positioning when used as a jig against the profile 3 and 2, and a hole position indicator part (second hole position indicator part) 10b that indicates the hole position when positioned by the positioning parts 25a, 25b, 7a, and 6. By changing how the end cap 4 is applied to the profile 3 and 2, a single hole position indicator part 10b can indicate different hole positions (see Figures 8-3 and 8-4). Therefore, multiple holes with different positions can be easily drilled in the profile 3 and 2 using the same end cap 4, thereby improving usability.

[0026] This structure comprises a profile (upper rail 1, lower rail 2, attachment 3) and end caps 4 attached to the longitudinal ends of the profiles 1, 2, and 3. The end caps 4 also serve as jigs for drilling holes in the profiles 1, 2, and 3. When used as a jig, the end caps 4 have positioning parts (second visible wall 7, folded portion 9, vertical edges 25a and horizontal edges 25b of the notch 25, tip 7a of the second visible wall 7, first visible wall 6, upper edge 6b of the first visible wall) that are placed against the profiles 1, 2, and 3 for positioning, and also indicate the hole position when positioned by the positioning parts 7, 9, 25a, 25b, 7a, 6, and 6b. The end cap 4 has hole position indicators (a first hole position indicator 10a, a second hole position indicator 10b, and a third hole position indicator 10c), and multiple hole position indicators 10a, 10b, and 10c are provided. By changing how the end cap 4 is applied to the profiles 1, 2, and 3, each hole position indicator 10a, 10b, and 10c can indicate different hole positions (see Figures 8-1, 8-2, 8-3, 8-4, 8-5, and 8-6). Therefore, multiple holes with different positions can be easily drilled in the profiles 1, 2, and 3 using the same end cap 4, thereby improving usability.

[0027] This structure comprises a profile (bottom rail) 2 and end caps 4 attached to the longitudinal ends of the profile 2. The end caps 4 also serve as jigs for drilling holes in the profile, and have positioning parts (second visible wall 7, folded portion 9, vertical edges 25a and horizontal edges 25b of the notch 25, upper edge 6b of the first visible wall 6, tip 7a of the second visible wall) for positioning against the profile 2 when used as a jig, and hole position indicator parts (first hole position indicator part 10a, second hole position indicator part 10b, third hole position indicator part 10c) for indicating the hole position when positioned by the positioning parts 7, 9, 25a, 25b, 6b, 7a. The surface of the end cap 4 that comes into contact with one side of the profile (upper wall 2b of the bottom rail) is the first visible wall 6, By changing the facing wall 8), it is possible to indicate different hole positions on one face 2b of the profile (see Figures 8-5, 8-6), or by changing the surface (facing wall 8) that the end cap 4 contacts with one face of the profile (site side wall 2a of the lower rail 2) and the surface (first facing wall 6) that the end cap contacts with the other face of the profile (upper wall 2b of the lower rail 2), it is possible to indicate hole positions on one face 2a and the other face 2b of the profile respectively (see Figures 8-2, 8-5). Therefore, it is possible to easily perform multiple hole processing at different positions on one face 2b of the profile 2, or to perform multiple hole processing at different positions on one face 2a and the other face 2b of the profile, using the same end cap 4, thereby improving usability.

[0028] The end cap 4 has an insertion portion 5 that is inserted into the profile (upper rail 1, lower rail 2), and multiple hole position indicators (first hole position indicator 10a, second hole position indicator 10b) are provided on one surface (face wall 8) of the insertion portion 5 (see Figures 8-1, 8-2, 8-3, 8-4, 8-6). By applying one surface 8 of the insertion portion 5 to the profile 1, 2, multiple holes with different positions can be easily drilled into the profile 1, 2.

[0029] The end cap 4 has an insertion portion 5 that is inserted into the profiles 1 and 2, and hole position indicators (third hole position indicator 10c, first and second hole position indicators 10a and 10b) are provided on different surfaces of the insertion portion 5 (first visible wall 6, inside wall 8) (see Figures 8-2, 8-4, 8-5, and 8-6). By applying the different surfaces 6 and 8 of the insertion portion 5 to the profiles 1 and 2, multiple holes with different positions can be easily drilled into the profiles 1 and 2.

[0030] The end cap 4 has an insertion portion 5 that is inserted into the profiles 1 and 2, and by providing a notch 25 in the insertion portion 5 to form multiple positioning portions 25a, 25b, 6, 7a, and 6b (see Figures 8-3, 8-4, 8-5, and 8-6), the variations in how the end cap is applied to the profiles 1 and 2 are increased, further improving ease of use.

[0031] The present invention is not limited to the embodiments described above. The material and cross-sectional shape of the profile can be changed as appropriate. The profile can be any component, not limited to the upper and lower rails of the fence panel. The shape and material of the end cap, the number and arrangement of the hole position indicators, the shape of the positioning part and how it is applied to the profile, etc., can be changed as appropriate. The present invention is not limited to fences, but can be applied to any structure having a profile and an end cap attached to its end (especially those in which the profile is cut to an appropriate length).
