Description

[Technical field]

[0001] The present invention relates to a fence in which the side ends of fence panels are connected at any angle. [Background technology]

[0002] Generally, various methods have been proposed for connecting fence panels, especially at corners, in fences that are installed along the boundary between properties. For example, there are methods in which connecting members are extended from the side ends of the panels toward the sides to connect the connecting members together, and methods in which connecting members are extended from the side ends of the panels and connected with connecting members. In the former, the connecting members are supported at their joints, and in the latter, the connecting members are supported at both ends of the connecting members.

[0003] With regard to the latter, for example, a dimensional adjustment device for a partition wall has been proposed in which a groove-shaped portion having an approximately U-shaped cross section extends from the shaft of a first hinge member pivoted to the side end of a vertically elongated wall body, and a slide piece extends from the shaft of a second hinge member pivoted to the opposing side end face of the wall body adjacent to the wall body, the slide piece is slidably inserted into the groove-shaped portion, and a screw whose tip can be pressed against the slide piece is screwed into the outer surface of the groove-shaped portion (see, for example, Patent Document 1).

[0004] The present applicant has also proposed a fence in which a number of fence panels attached to posts erected on the ground at appropriate intervals are connected horizontally via connecting members, the connecting members being rotatably connected to both sides of a vertically elongated base plate via fitting portions to which panel mounting members are attached, and a cover portion which has a U-shaped cross section formed on the panel mounting member is attached to cover the side ends of the fence panels, the cover portion being attached so as to be slidable in the vertical direction relative to the fence panels, and the downward sliding of the cover portion is prevented by an end member provided at the upper end of the panel mounting member (see, for example, Patent Document 2).

[0005] [Patent Document 1] Jpn. Jpn. Published No. 59-3111 [Patent Document 1] JP 2009-1968 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] Incidentally, since it is preferable for the corners of a fence to have a structure that can absorb various dimensional errors that occur during construction, the aforementioned size adjustment device has a fitting structure between a grooved part and a sliding piece that can be fixed with a screw, which is easy to install, but simply screwing in with a screw may cause the screw to loosen over time. On the other hand, with the aforementioned connecting member, the base material is formed from a single member, so the error that can be absorbed by the size adjustment work is relatively small.

[0007] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a fence having corner members which can be easily adjusted in size and which are less likely to come loose, thereby solving the above-mentioned problems. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention has the following configuration: That is, the fence according to the present invention is a fence in which fence panels are connected to each other via corner members, the corner members include a front plate portion and a rear plate portion that overlap in the front-to-rear direction, a side end portion of the front plate portion is rotatably connected to one of the fence panels, and a side end portion of the rear plate portion is rotatably connected to the other fence panel, the front plate portion and the rear plate portion are fastened together by a fastening device, the fastening device includes a screw member having a head portion, a root portion and a threaded portion, and being inserted into a hole portion that penetrates in the front and rear plate portions in the front and rear directions, a spring member that is inserted into the threaded portion, and a nut member that is screwed into the threaded portion, the spring member having a folded portion whose upper end portion is folded back so as to be able to engage with the root portion, and a folded portion whose lower end portion is folded in the same direction as the folded portion, and the folded portion and the folded portion are each able to abut against the rear plate portion.

[0009] In the fence according to the present invention, the angular root portion of the screw member may have a flange portion on the threaded portion side that is larger than the angular root portion. Effect of the Invention

[0010] According to the present invention, the front and rear plate portions allow good dimensional adjustment in the width direction, and the front and rear plate portions can be firmly connected together by the fastening device. [Brief description of the drawings]

[0012] Next, the best mode for carrying out the present invention will be described in detail with reference to the drawings. Fig. 1 is an explanatory diagram showing one embodiment of a fence according to the present invention, in which (a) is a plan view and (b) is a front view. In the drawing, 10 is a fence panel, and 20 is a corner member that connects the fence panels 10 to each other, and in the fence 100 according to the present invention, the fence panels 10 are connected to each other via the corner members 20. Here, the horizontal direction is the same direction as the width direction of the fence panel 10 in Fig. 1, and the vertical direction is the same direction as the vertical direction in Fig. 1. In addition, the front-rear direction is the front-rear direction in Fig. 1, when the fence panel 10 is used as the boundary, and the side where the support 30 for mounting the fence panel 10 is installed is the rear side, and the opposite side is the front side.

[0013] The fence panel 10 comprises flat panel materials 12 attached to a rectangular frame 11, and in this embodiment, multiple panels are connected horizontally and stacked vertically in two stages, and are attached to supports 30 erected on the installation surface. As shown in Fig. 1(a), a fence panel 10 arranged in the left-right direction and a fence panel 10 arranged in the up-down direction are connected via corner members 20.

[0014] 2 is an explanatory diagram of the corner member 20 in FIG. 1, where (a) is a partially enlarged view of the vicinity of the corner member 20 in (a) of FIG. 1, and (b) is an enlarged cross-sectional view of the corner member 20. The corner member 20 is arranged with a vertical front plate portion 21 and a rear plate portion 22 overlapping in the front-rear direction. The front plate portion 21 is rotatably connected to one of the fence panels 10 at the upper left in FIG. 2. Specifically, a side plate portion 23 attached to a side end portion of one of the fence panels 10 and a side end portion of the front plate portion 21 are rotatably connected by a hinge portion 24 whose axis is in the vertical direction. In addition, the rear plate portion 22 is connected to the other fence panel 10 at the lower right in FIG. 2. Specifically, a side plate portion 25 attached to a side end portion of the other fence panel 10 and a side end portion of the rear plate portion 22 are rotatably connected by a hinge portion 26 whose axis is in the vertical direction.

[0015] As a result, the position of the front plate portion 21 can be changed in the R1 direction, and the position of the rear plate portion 22 can be changed in the R2 direction, so that the positions of the front plate portion 21 and the rear plate portion 22 can be changed according to the angle between the width direction of one fence panel 10 and the width direction of the other fence panel 10, and the corner member 20 can provide a concealing function near the connection point between the fence panels 10. The front plate portion 21 and the rear plate portion 22 are fastened together at the overlapping point by a fastening device 40. The fastening device 40 includes a screw member 50, a spring member 60, and a nut member 70, and the front plate portion 21 and the rear plate portion 22 are fastened together by the screw member 50, the spring member 60 attached thereto, and the nut member 70.

[0016] Next, the fastening structure between the front plate 21 and the rear plate 22 will be described. Fig. 3 is a view taken along the arrow A in Fig. 1 and is an enlarged view of the fastening device 40 and its vicinity, Fig. 4 is an explanatory diagram showing the relationship between the corner member 20 and the fastening device 40 in Fig. 3, and Fig. 5 is an explanatory diagram of a screw member 50 of the fastening device 40, where (a) is a front view and (b) is a side view. As shown in Fig. 3, the screw member 50 is inserted through a front hole 21a penetrating the front and rear of the front plate 21 and a rear hole 22a penetrating the front and rear of the rear plate 22.

[0017] 4, since the front hole 21a is a vertically long hole and the rear hole 22a is a horizontally long hole, if the front hole 21a and the rear hole 22a are positioned to overlap in the front-to-rear direction and if the screw member 50 can be inserted, the front plate 21 and the rear plate 22 can be fastened together by the fastening device 40. That is, within the range in which the screw member 50 can be inserted, the positions of the front plate 21 and the rear plate 22 in the height direction and the width direction can be adjusted.

[0018] As shown in Fig. 5, the screw member 50 has a head 51, a square root portion 52 having a rectangular cross section, and a threaded portion 53 having a male thread formed on the outer periphery, which are arranged in this order. In contrast, as shown in Fig. 4, the front hole portion 21a has a wide portion 21b through which the head 51 of the screw member 50 can be inserted, and a narrow portion 21c through which the head 51 cannot pass but the threaded portion 53 can pass and through which rotation around the axis of the square root portion 52 is restricted, with the wide portion 21b arranged at the top and the narrow portion 21c arranged at the bottom. In this embodiment, the vertical dimensions of the rear hole portion 22a are approximately the same as those of the front hole portion 21a.

[0019] This allows the worker to insert the screw member 50 from the head 51 side into the rear hole 22a and the front hole 21a from the rear side of the fence 100 on which the support 30 is erected. Thereafter, by moving the square root portion 52 downward along the narrow width portion 21c, the screw member 50 is restricted from rotating about its longitudinal axis, and the head 51 is engaged with the front hole portion 21a, allowing the screw member 50 to be temporarily fastened to the front plate portion 21 and the rear plate portion 22.

[0020] Next, a method of fastening the front plate portion 21 and the rear plate portion 22 will be described. FIG. 6 is an explanatory diagram of the spring member 60 of the fastening device 40, where (a) is a front view, (b) is a side view, (c) is an enlarged cross-sectional view of line BB in (b), FIG. 7 is an explanatory diagram showing the relationship between the screw member 50 and the spring member 60, and FIG. 8 is an explanatory diagram showing the relationship between the screw member 50, the spring member 60, and the nut member 70. As shown in FIG. 7(a), the spring member 60 is attached after the screw member 50 is inserted into the front plate portion 21 and the rear plate portion 22. As shown in FIG. 6, the spring member 60 has a vertical plate-shaped base plate portion 61 made of metal, a folded portion 62 formed by folding back the upper end portion of the base plate portion 61, and a folded portion 63 formed by folding back the lower end portion of the base plate portion 61 in the same direction as the folded back direction of the folded portion 62. The base plate portion 61 has a hole portion 61a penetrating in the thickness direction. The folded portion 62 hangs down, and its lower end has a notch 62 a cut out toward the top, so that the notch 62 a can fit into the square root portion 52 .

[0021] 7(b), the threaded portion 53 of the screw member 50 can be passed through the hole 61a of the base portion 61, and the notched portion 62a of the folded portion 62 can be engaged with the square root portion 52. In other words, since the folded portion 62 can be easily arranged on the upper side and the bent portion 63 on the lower side, there is no need to correct misalignment of the spring member 60 or adjust its position during the fastening operation.

[0022] In this embodiment, the screw member 50 has a flange portion 54 that is larger than the root portion 52 on the threaded portion 53 side of the root portion 52 .

[0023] As a result, as shown in FIG. 7(b), when the screw member 50 is temporarily fixed to the front plate portion 21 and the rear plate portion 22, the screw member 50 may tilt diagonally downward on the screw portion 53 side. However, even if the screw member 50 slides toward the screw portion 53 side after the cutout portion 62a is engaged with the angular root portion 52, it will stop at the flange portion 54, so that the spring member 60 will not come off the screw member 50 and can be temporarily fixed.

[0024] When the cutout portion 62a is engaged with the angular root portion 52, the folded-back portion 62 and the bent portion 63 of the screw member 50 face the rear plate portion 22, and the vertical dimension from the folded-back portion 62 to the bent portion 63 is longer than the vertical dimension of the rear hole portion 22a.

[0025] This allows the folded-back portion 62 to face the rear plate portion 22 above the rear hole portion 22a, and the bent portion 63 to face the rear plate portion 22 below the rear hole portion 22a.

[0026] As shown in (a) of FIG. 8, when the nut member 70 is screwed into the threaded portion 53 of the screw member 50, the nut member 70 comes into contact with the base plate portion 61 of the spring member 60 as shown in (b) of FIG. 8. As the screwing operation continues, the spring member 60 moves toward the rear plate portion 22, so that the folded-back portion 62 comes into contact with the rear plate portion 22 above the rear hole portion 22a, and the bent portion 63 comes into contact with the rear plate portion 22 below the rear hole portion 22a. As the screwing operation continues further, the folded-back portion 62 and the bent portion 63 press the rear plate portion 22 toward the front plate portion 21 as shown in (c) of FIG. This allows the fastening device 40 to firmly fasten the rear plate portion 22 and the front plate portion 21 together.

[0027] The folded-back portion 62 and the bent portion 63 are formed flat at the portions where they come into contact with the rear plate portion 22, so that the rear plate portion 22 can be reliably pressed against the front plate portion 21 and firmly fastened.

[0028] The thickness dimension of the root portion 52, i.e., the dimension from the head portion 51 to the flange portion 54, is approximately the same as the total thickness of the front plate portion 21, the rear plate portion 22 and the folded portion 62 of the spring member 60, so that a temporary fastening state in which the cutout portion 62a of the folded portion 62 is engaged with the root portion 52 can be easily achieved by inserting the screw member 50 through the rear hole portion 22a and the front hole portion 21a.

[0029] In this embodiment, as shown in FIG. 1, the fastening devices 40 are used at two different locations in the vertical direction on the corner member 20, but the number of fastening devices 40 used can be appropriately set depending on the vertical length of the corner member 20.

[0030] The fence 100 according to the present invention is a fence 100 in which fence panels 10 are connected to each other via corner members 20, and the corner members 20 have a front plate portion 21 and a rear plate portion 22 which overlap in the front-to-rear direction, a side end portion of the front plate portion 21 is rotatably connected to one fence panel 10, and a side end portion of the rear plate portion 22 is rotatably connected to the other fence panel 10, and the front plate portion 21 and the rear plate portion 22 are fastened together by a fastening device 40, and the fastening device 40 has a head portion 51, a root portion 52 and a screw portion 53, and The spring member 60 has a folded portion 62 whose upper end is folded back so as to be engageable with the angular root portion 52, and a bent portion 63 whose lower end is bent in the same direction as the folded portion 62, and the folded portion 62 and the bent portion 63 are each capable of abutting against the rear plate portion 22.

[0031] This makes it easy to adjust the widthwise dimensions of the front plate 21 and the rear plate 22 within a range in which the screw member 50 of the fastening device 40 can be inserted. Also, since the spring member 60 has a folded portion 62 whose upper end is folded back and can be engaged with the square root portion 52, it is not necessary to correct a misalignment of the spring member 60 or adjust its position when operating the fastening device 40. Furthermore, since the folded portion 62 and the bent portion 63 of the spring member 60 can abut against the rear plate 22, the rear plate 22 can be pressed against the front plate 21, thereby firmly fastening the front plate 21 and the rear plate 22 together.

[0032] In the fence 100 according to the present invention, the square root portion 52 of the screw member 50 may have a flange portion 54 on the threaded portion 53 side that is larger than the square root portion 52 .

[0033] As a result, even if the spring member 60 slides toward the screw portion 53 after being engaged with the square root portion 52, it is stopped by the flange portion 54, so that the spring member 60 will not come off the screw member 50 and can be temporarily fixed. [Explanation of symbols]
