Description

[Technical Field]

[0001] The present invention relates to a fence with a hidden barb that is installed along the boundary of a property such as a house or condominium or along the boundary of a neighboring property. [Background technology]

[0002] Generally, fences installed along the boundaries of residential or factory premises are constructed by fixing panels made of mesh panels, lattice material, metal, wood, synthetic resin, etc. to posts, and connecting these panels in the width direction (left and right direction).

[0003] Among these, so-called shinobi-gaeshi (secret guard) type fences are used, in which panels are arranged in multiple vertical rows with the topmost wall panel tilted outside the premises to prevent people from climbing over the fence from outside.

[0004] In the case of a shinobi-gaeshi fence, it was necessary to use posts with their top ends angled outside the site in order to secure the top panel material. This required posts that were partially bent, making them difficult to transport.

[0005] Therefore, in this application, Patent Document 1 proposes a fence with a hidden guardrail, which is composed of first posts erected on the ground at appropriate intervals, a first fence panel (panel material) erected between the first posts, a second post detachably attached to the top end of the first post, and a second fence panel (panel material) erected between the second posts. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-301629 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0007] Here, Patent Document 1 proposes two connection configurations for the first support and the second support: one in which an engagement portion is provided on the second support and this engagement portion is fixed to the first support, and another in which a rotating portion is provided at the top of the second support so that it can rotate relative to the first support.

[0008] When erecting panels at corners of a site by erecting posts at such corners, it is necessary to calculate the inclination angle of the second post located at the corner each time, depending on the angle of the corner, etc.

[0009] In the supports used in corners, slight construction errors and processing errors, such as errors in the installation position or slight tilt of the first support, slight processing errors in the engaging part, slight construction errors when fastening the engaging part to the first support, and the orientation of the second support, can act in combination to cause errors in three dimensions: length, width, and height.

[0010] For this reason, in terms of design, it is possible to calculate the inclination of the second support post when using a support post at a corner, but as mentioned above, three-dimensional errors in length, width, and height can occur, so there was a need for a fence with a hidden guardrail that was easy to install even if such errors occurred.

[0011] To provide a fence with a hidden guardrail that solves the above-mentioned problems and makes it easy to install a panel material for a hidden guardrail at a corner by absorbing an error in construction of a support post to be installed at the corner, even if the error occurs when the panel material for a hidden guardrail is installed at the corner. [Means for solving the problem]

[0012] In order to achieve the above object, the present invention has the following configuration: That is, the fence with a hidden bar according to the present invention comprises a corner post having an inclined corner portion at an upper portion thereof inclined in a predetermined direction, a first post standing in one direction from the corner post at a distance and having a first inclined portion at an upper portion thereof inclined in the predetermined direction, a second post standing in another direction from the corner post at a distance and having a second inclined portion at an upper portion thereof inclined in the predetermined direction, a panel material attached between the inclined corner portion and the first inclined portion, and a panel member attached to the inclined corner portion and the inclined corner portion. The aforementioned and another panel material attached between the second portion, each panel material having a connecting member that protrudes toward the corner inclined portion and connects to the corner inclined portion, and the connecting member is sandwiched between the corner inclined portion and a pressing member arranged opposite the corner inclined portion.

[0013] In the present invention, the connecting member may have a convex portion protruding toward the corner inclined portion and a concave portion formed on the opposite side of the convex portion and recessed toward the corner inclined portion, and a portion of the pressing member may be arranged within the concave portion.

[0014] Furthermore, in the present invention, the connecting members may be attached to the upper and lower portions of each side of the panel material. [Effects of the Invention]

[0015] According to the present invention, even if there are slight processing errors in the components or construction errors during construction, the connecting member of the panel material can absorb these errors by being clamped between the corner inclined portion and the pressing member, and the panel material can be attached to the corner inclined portion.

[Figure 11] FIG. 10 is a view taken along arrow D in FIG. 9. DETAILED DESCRIPTION OF THE INVENTION

[0017] Next, a best mode for carrying out the present invention will be described in detail with reference to the drawings. Fig. 1 is a front view of one embodiment of a fence with a visor 100 according to the present invention, Fig. 2 is a left side view of Fig. 1, Fig. 3 is a cross-sectional view along line AA of Fig. 1, and Fig. 4 is a view as viewed from the arrow B of Fig. 1. In the drawings, 10, 20, and 30 denote corner posts, a first post, and a second post, 40 denotes corner post 10 and a panel member attached between first post 20 and second post 30, and 50 denotes a connecting member connecting panel member 40 to corner post 10. Here, the left-right and up-down directions of the fence with a visor 100 are the same as those shown in Fig. 1 unless otherwise specified. The front side of Fig. 1 is the front side, and the back side is the rear side. The following description will be based on this.

[0018] The fence with barbs 100 according to this embodiment has first posts 20 erected at intervals in one direction and second posts 30 erected at intervals in the other direction. Corner posts 10 are erected at corners where one direction intersects with the other direction.

[0019] The first support 20 has a support body 21 disposed vertically with its lower portion buried in the installation surface, and a first inclined portion 22 inclined in a predetermined direction from the upper end of the support body 21. In this embodiment, the first inclined portion 22 is inclined at 30 degrees relative to the support body 21 toward the front side, which is outside the site.

[0020] The second support 30 has a similar configuration to the first support 20, and includes a support body 31 disposed vertically with its lower portion buried in the installation surface, and a second inclined portion 32 inclined in a predetermined direction from the upper end of the support body 31. In this configuration, the second inclined portion 32 is inclined at 30 degrees toward the outside of the site.

[0021] The corner support 10 has a support body 11 that is disposed vertically with its lower portion buried in the installation surface, and a corner inclined portion 12 that is inclined in a predetermined direction from the upper end of the support body 11. In this embodiment, the intersection angle between one direction and the other direction is 90 degrees, and the corner inclined portion 12 is inclined at approximately 39 degrees toward the outside of the site. This inclination angle is set so that when the corner inclined portion 12 is viewed from both the one direction and the other direction, the inclination angle is the same as the inclination angle of the first inclined portion 22 and the second inclined portion 32 (30 degrees in this embodiment).

[0022] The fence with barbs 100 according to this embodiment is a so-called outer barb type, and Fig. 1 shows an outer corner portion. Although not explained further, a similar structure can also be used for the inner corner portion of an inner barb type.

[0023] In this embodiment, the first support 20 uses steel pipes with a rectangular cross section for both the support body 21 and the first inclined portion 22, and the upper end of the support body 21 and the lower end of the first inclined portion 22 are joined by welding. Although not shown, the joining means may be, for example, a fitting portion that fits into the upper end of the support body at the lower end of the first inclined portion, and the fitting portion may be fitted into the upper end of the support body and fastened to the support body using bolts and nuts to join the support body and the first inclined portion. Similar joining means can also be used for the second support 30 and corner support 10, so a description thereof will be omitted.

[0024] A panel material 70 is attached between the support body 11 of the corner support 10 and the support body 21 of the first support 20. The panel material 70 has a rectangular plate material 71 and a frame body 72 attached to the outer periphery of the plate material 71. The panel material 70 is attached between the support bodies 11, 21 by mounting members 73. In this embodiment, the panel materials 70 are arranged in two tiers, one above the other, but the height and number of panel materials 70 can be set appropriately depending on the height of each support body 11, 21.

[0025] A panel material 70 is attached between the support body 11 of the corner support 10 and the support body 31 of the second support 30. The attachment structure of the panel material 70 is the same as that described above, so a detailed explanation will be omitted.

[0026] As shown in FIGS. 1 and 4 , a panel 40 is attached between the corner inclined portion 12 of the corner support 10 and the first inclined portion 22 of the first support 20. In this embodiment, the panel 40 includes a rectangular plate 41, a pair of vertical frame members 42, 43 attached to the left and right sides of the plate 41, and a pair of horizontal frame members 44, 44 attached to the top and bottom of the plate 41. The pair of vertical frame members 42, 43 and the pair of horizontal frame members 44, 44 form a frame 45. In other words, the vertical frame members 42, 43 are arranged on the sides of the panel 40. In this embodiment, the vertical and horizontal frame members have a U-shaped cross section, and the smaller vertical frame members 42, 43 are inserted inside both longitudinal ends of the larger horizontal frame members 44, 44 to form the rectangular frame 45.

[0027] As shown in Figures 3 and 4, a connecting metal fitting 23 for connecting to a panel material 40 is fixed to the first inclined portion 22. The connecting metal fitting 23 has a panel connecting portion 24 that protrudes in a first direction, and the panel connecting portion 24 is arranged on the rear side of the panel material 40. In this embodiment, the panel connecting portion 24 and the panel material 40 are fastened with bolts and nuts, and two connecting metal fittings 23 are fixed at intervals above and below the length direction of the first inclined portion 22. Note that the panel material 40 is also attached between the first inclined portions 22 via the connecting metal fittings 23, but a detailed description thereof will be omitted.

[0028] FIG. 5 is an enlarged view of the area around the corner inclined portion 12 in FIG. 4 , FIG. 6 is an explanatory diagram showing the relationship between the connecting member 50 and the retaining member 60 in FIG. 5 , and FIG. 7 is an explanatory diagram of the connecting member 50, where (a) is a plan view, (b) is a front view, and (c) is a right side view. FIG. 8 is an explanatory diagram of the retaining member 60, where (a) is a plan view, (b) is a front view, and (c) is a right side view. A connecting member 50 for connecting the corner inclined portion 12 to the vertical frame member 43 of the panel material 40 is fixed to the vertical frame member 43 on the corner inclined portion 12 side. As shown in FIG. 6 , the connecting member 50 has a panel fixing portion 51 fixed to the vertical frame member 43 and a clamping portion 52 attached to the corner inclined portion 12. The panel fixing portion 51 is formed in a vertical plate shape and has a through-hole 51a penetrating in the front-to-rear direction, which is the thickness direction. The vertical frame member 43 also has a through-hole (not shown) penetrating in the front-to-rear direction. The panel fixing portion 51 is fixed to the vertical frame member 43 by inserting a bolt member 91 from the through hole 51a of the panel fixing portion 51 to the through hole of the vertical frame member 43 and screwing a nut member 92 into the threaded portion of the bolt member 91.

[0029] The clamping portion 52 protrudes from the panel fixing portion 51 toward the corner inclined portion 12, and in this embodiment is disposed on the rear side of the corner inclined portion 12. The tip side of the clamping portion 52 is bent in a direction away from the corner inclined portion 12 to form a convex portion 53 that abuts against the rear surface of the corner inclined portion 12, and a concave portion 54 is formed on the opposite side, giving the clamping portion 52 an L-shaped cross section. Note that, in the corner support 10, the front side is the side on which the corner support 10 is inclined, and the rear side is the opposite side.

[0030] Here, since the rear surface of the corner inclined portion 12 is not necessarily located on the left-right extension line of the panel fixing portion 51, in this embodiment, the panel fixing portion 51 has a protruding portion 55 that protrudes rearward from the corner inclined portion 12 side, and the protruding tip side of this protruding portion 55 is formed toward the rear surface of the corner inclined portion 12 to form the clamping portion 52.

[0031] A pressing member 60 is attached to the rear surface of the corner inclined portion 12 with the clamping portion 52 of the connecting member 50 therebetween. As shown in FIG. 8 , the pressing member 60 is in the form of a vertical plate and is arranged along the length of the rear surface of the corner inclined portion 12. The pressing member 60 has a through hole 60a that penetrates in the thickness direction, and is attached to the corner inclined portion 12 by a bolt member 93 that penetrates through through holes 12a, 12a formed on the front and rear surfaces of the corner inclined portion 12, and a nut member 94 that screws into the threaded portion of the bolt member 93. By further tightening the nut member 94, the clamping portion 52 can be clamped between the corner inclined portion 12 and the pressing member 60.

[0032] This makes it possible to fix the clamping portion 52 to the corner inclined portion 12 , and the panel material 40 can be attached between the corner inclined portion 12 and the first inclined portion 22 .

[0033] The corner posts 10 are erected at the corners of the fence 100 with hidden bars. If the intersection angle of the corner changes due to construction errors, the design requires that the tilt direction of the corner sloped portion 12 of the corner post 10 also be changed, resulting in a change in the corresponding slope angle of the corner sloped portion 12. If construction errors occur in the tilt direction, a discrepancy will occur between the slope angles of the first sloped portion 22 and the second sloped portion 32. In other words, when the first posts 20 are positioned at a predetermined interval, construction errors that occur in the corner posts 10 are likely to be larger than construction errors that may occur in the first posts 20. When processing errors in the corner posts 10 are added to this, the construction errors that occur in the corner posts 10 are likely to be relatively large.

[0034] Therefore, the connecting member 50 and the retaining member 60 have a structure that makes it easier to absorb the above-mentioned errors. First, in the connecting member 50, the through hole 51a of the panel fixing portion 51 is horizontally elongated in the left-right direction. This makes it possible to adjust the fixing position of the panel fixing portion 51 relative to the vertical frame member 43 within a range in which the bolt member 91 can be inserted from the horizontally elongated through hole 51a into the through hole of the vertical frame member 43. In this embodiment, the convex portion 53 can be designed to abut against the rear surface of the corner inclined portion 12 along the forming direction of the convex portion 53. Even if the above-mentioned construction error occurs, the error can be reduced by adjusting the fixing position of the panel fixing portion 51.

[0035] Next, the pressing member 60 is formed with a U-shaped cross section having a base 61 with a through hole 60a formed therein and a pair of side portions 62 protruding in the same direction from both widthwise ends of the base 61, and one of the side portions 62 can be positioned within the recess 54 of the clamping portion 52.

[0036] Next, an example of the installation procedure for the connecting member 50 will be described with reference to FIG. 6 . The connecting member 50 is temporarily fixed to the vertical frame member 43 using bolt members 91 and nut members 92, allowing the panel fixing portion 51 to be adjusted in its fixed position. Next, the pressing member 60 is temporarily fixed to the corner inclined portion 12 using bolt members 93 and nut members 94, and the side portion 62 is positioned in the recessed portion 54 of the clamping portion 52. When the nut member 94 is screwed, the side portion 62 moves toward the back of the recessed portion 54 and abuts against it. When the nut member 94 is further screwed, the side portion 62 moves the clamping portion 52 toward the rear surface of the corner inclined portion 12 through the recessed portion 54. When the nut member 94 is further tightened, the protruding portion 53 presses against the rear surface of the corner inclined portion 12, fixing the clamping portion 52 between the corner inclined portion 12 and the pressing member 60, completing the installation procedure.

[0037] The side portion 62 of the pressing member 60 has a fitting portion 63 into which the clamping portion 52 of the connecting member 50 fits. In this embodiment, the fitting portion 63 is a notch formed from the tip side of the side portion 62 toward the base portion 61, and is configured to allow the clamping portion 52 to be placed therein. As a result, if the clamping portion 52 is fitted into the fitting portion 63 during the above-mentioned installation work, it will be less likely to come off the pressing member 60, and the clamping portion 52 will be more easily clamped between the corner inclined portion 12 and the pressing member 60.

[0038] A screen member 80 is attached to the front side of the vertical frame member 43 of the panel material 40 to hide the gap between the vertical frame member 43 and the corner inclined portion 12. In this embodiment, the screen member 80 is a long plate extending in the length direction of the vertical frame member 43, and is fixed to the vertical frame member 43 using a bolt member 91 and a nut member 92 for fixing the connecting member 50 to the vertical frame member 43.

[0039] The mounting structure of the panel material 40 to the corner inclined portion 12 is similar to the mounting structure of the panel material 40 on the first support 20 side to the corner inclined portion 12, so the same components are given the same symbols and detailed explanations are omitted.

[0040] With this structure, the panel material 40 on the first support post 20 side and the panel material 40 on the second support post 30 side can be attached to the corner inclined portion 12 using the connecting member 50 and the pressing member 60, respectively.

[0041] Figures 9 to 11 are explanatory views showing another embodiment of the fence with barbs 100 according to the present invention, with Figure 9 being a front view, Figure 10 being a cross-sectional view taken along line CC in Figure 9, and Figure 11 being a view as seen from the arrow D in Figure 9. A fence with barbs 200 according to the present invention differs from the fence with barbs 100 shown in Figures 1 to 8 mainly in the direction of inclination of the barbs. Therefore, the following description will focus on the differences from Figures 1 to 7, and other components that are the same as those already described will be given the same reference numerals and will not be described again.

[0042] As shown in Figure 10, in the fence with barbs 200 according to this embodiment, the first inclined portion 22 of the first post 20 is inclined at 30 degrees toward the rear, which is the inside of the site, relative to the post body 21. In other words, the fence with barbs 200 according to this embodiment is a so-called inside barb type, and Figure 9 shows an outside corner portion. Note that a similar structure can also be used for the inside corner portion of an outside barb type.

[0043] In addition, the screen material 80 for hiding the gap between the vertical frame member 43 and the corner inclined portion 12 is attached to the same rear side as the connecting member 50. In other words, the vertical frame member 43, the screen material 80, and the connecting member 50 are arranged in this order, and are fixed via bolt members 91 and nut members 92.

[0044] With these structures, in the fence with barbs 200, the panel material 40 on the first support 20 side and the panel material 40 on the second support 30 side can be attached to the corner inclined portion 12 using the connecting member 50 and the holding member 60, respectively.

[0045] The fence with a hidden bar 100 according to the present invention comprises a corner support 10 having a corner inclined portion 12 at an upper portion inclined in a predetermined direction; a first support 20 standing apart from the corner support 10 in one direction and having a first inclined portion 22 at an upper portion inclined in a predetermined direction; a second support 30 standing apart from the corner support 10 in the other direction and having a second inclined portion 32 at an upper portion inclined in a predetermined direction; a panel material 40 attached between the corner inclined portion 12 and the first inclined portion 22; and another panel material 40 attached between the corner inclined portion 12 and the second inclined portion 32, each panel material 40 having a connecting member 50 that protrudes toward the corner inclined portion 12 and connects to the corner inclined portion 12, and the connecting member 50 is sandwiched between the corner inclined portion 12 and a pressing member 60 arranged opposite the corner inclined portion 12.

[0046] As a result, due to slight processing errors in the components or slight construction errors during construction, the connecting member 50 may come into contact with the corner inclined portion 12 in a smaller area than designed, or may not come into contact at all, leaving a small gap. However, by clamping the connecting member 50 between the corner inclined portion 12 with the pressing member 60, the above-mentioned errors can be absorbed, and the panel material 40 and the panel material 40 can be attached to the corner inclined portion 12.

[0047] In the present invention, the connecting member 50 may have a convex portion 53 protruding toward the corner inclined portion 12 and a concave portion 54 formed on the opposite side of the convex portion 53 and recessed toward the corner inclined portion 12, and a part of the pressing member 60 may be arranged within the concave portion 54.

[0048] As a result, even if an external force acts in a direction in which the connecting member 50 is pulled out, the retaining member 60 arranged in the recess 54 prevents the connecting member 50 from being pulled out from between the corner inclined portion 12 and the retaining member 60, so that the panel material 40 and the panel material 40 can be maintained in a state where they are attached to the corner inclined portion 12.

[0049] In the present invention, the connecting members 50 may be attached to the upper and lower portions of each side of the panel material 40.

[0050] As a result, although the degree of the above-mentioned error may vary depending on the height position, adjustments can be made to reduce the error at each height position, so that the panel material 40 and the panel material 40 can be firmly attached to the corner inclined portion 12.
