Patent Document 1

[0005] Here, an example of a conventional fence joint will be described with reference to the drawings. Hereinafter, this conventional fence joint will be referred to as a conventional joint.

[0006] FIG. 14 is a front view showing a state where a panel is fixed to a support column by a conventional joint, FIG. 15 is a plan view showing a state where a panel is fixed to a support column by a conventional joint, and FIG. 16 is a side view showing a state where a panel is fixed to a support column by a conventional joint.

[0007] In FIGS. 14 to 16, a panel 11 is formed by arranging vertical wire rods 12 and horizontal wire rods 13 in a lattice pattern and welding their respective intersections. A body edge 14 of the panel 11 is formed by welding a horizontal wire rod 13 to the outside of the upper end of a vertically bent wire rod 12 in a ring shape. Note that the illustrated body edge indicates an upper body edge.

[0008] Panel 11 is fixed to a column 16 made of a round pipe via a conventional joint 15. The conventional joint 15 includes an insertion portion 17 made of a steel plate and inserted into a body edge 14, and a fixing portion 18 fixed to the column 16. In the insertion portion 17, a screwing portion 19 of a screw 23 described later is formed by punching out a part of the insertion portion 17 by press working, and a bolt hole 21 is formed in the fixing portion 18.

[0009] To fix the panel 11 to the column 16 with the conventional joint 15 configured as described above, the insertion portion 17 of the conventional joint 15 is inserted into the body edge 14 of the panel 11, a fixing fitting 22 is applied to the body edge 14, and the screw 23 is passed through the fixing fitting 22 and screwed into the screwing portion 19 of the insertion portion 17.

[0010] After fixing the conventional joints 15 to the body edges 14 of the left and right panels 11 in this way, a bolt 24 is passed through the column 16 from the bolt hole 21 of the fixing portion 18 of one conventional joint 15 and through the bolt hole 21 of the fixing portion 18 of the other conventional joint 15, and a nut 25 is tightened. Thereby, the panel 11 is fixed to the column 16 by the conventional joint 15. Summary of the Invention Problems to be Solved by the Invention

[0011] As described above, according to the conventional joint 15, the panel 11 can be fixed to the column 16 However, the process of attaching the conventional joints 15 fixed to the left and right panels 11 to the column 16 with bolts 24 and nuts 25 requires work from both sides of the panel 11, and work by two or more people has been required.

[0012] In addition, since the two panels 11 positioned on the left and right are fixed by a single bolt 24, when removing the attached panel 11 during maintenance or the like, the conventional joints 15 of the left and right panels 11 must be removed simultaneously. Also, at this time, it is necessary to support the panel 11 that does not need to be removed so that it does not fall. Thus, there has been a problem that the work process becomes complicated when removing only some of the panels 11 of the entire fence.

[0013] In addition, since the conventional joint 15 has a structure in which the insertion portion 17 is inserted into the body edge 14 of the panel 11, when the shape of the body edge 14 differs depending on the panel 11 used, a plurality of types of conventional joints 15 adapted to the shape of each body edge 14 are required, resulting in problems such as an increase in manufacturing cost and complicated parts management.

[0014] Therefore, the present invention has been made in view of the above matters, and an object thereof is to provide a fence joint that can easily perform the attachment and detachment operations of a panel to a support column from one side of the panel and can attach the panel to the support column regardless of the shape of the body edge.

Mode for Carrying Out the Invention

[0026] Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. Note that the following embodiments do not limit the invention according to each claim, and not all combinations of features described in the embodiments are essential for the solution means of the invention.

[0027] [First Embodiment] FIG. 1 is a perspective view seen from the front side in the depth direction showing one form of a fence configured using a fence joint according to the first embodiment of the present invention, FIG. 2 is a perspective view seen from the back side in the depth direction showing one form of a fence configured using a fence joint according to the first embodiment of the present invention, FIG. 3 is a cross-sectional view taken along line A-A of FIG. 1, FIG. 4 is a cross-sectional view taken along line B-B of FIG. 1, FIG. 5 is a perspective view seen from the front side in the depth direction showing a joint body of a fence joint according to the first embodiment of the present invention, FIG. 6 is a perspective view seen from the back side in the depth direction showing a joint body of a fence joint according to the first embodiment of the present invention, FIG. 7 is a cross-sectional view taken along line C-C of FIG. 5, FIG. 8 is a perspective view showing a fastener of a fence joint according to the first embodiment of the present invention, and FIG. 9 is a perspective view showing a process of attaching a panel using a fence joint according to the first embodiment of the present invention. In this specification, the front side and the back side in the depth direction are defined as the directions of the arrows shown in FIGS. 1 and 2. Also, in this specification, the width direction of the fence is defined as the direction of the arrows shown in FIGS. 1 and 2.

[0028] As shown in FIGS. 1 and 2, the fence joint 1 according to the present embodiment is attached to the support column 16 and fixes the panel 11 to the support column 16.

[0029] The support column 16 is, for example, a round pipe-shaped steel pipe, and its lower end is buried in a foundation such as mortar and erected on the ground. Further, a plurality of support columns 16 are installed at intervals along the site boundary. Note that the support column 16 is not limited to a round pipe-shaped steel pipe, and may be a pipe with a polygonal cross-sectional shape, or may be made of a metal such as a stainless alloy or an aluminum alloy. Also, the method of erecting the support column 16 is not limited to burying it in a foundation such as mortar, and it may be erected by a known method such as directly driving the support column 16 into the ground surface or installing a base plate on a concrete surface or the like and then erecting it.

[0030] The panel 11, similar to the conventional embodiment, has a plurality of vertical wire members 12 and a plurality of horizontal wire members 13 arranged in a grid pattern. The vertical wire members 12 and the horizontal wire members 13 are, for example, made of iron wire, and respective intersections arranged in a grid pattern are connected by welding. Note that it is preferable that the vertical wire members 12 and the horizontal wire members 13 are subjected to zinc plating, electrostatic powder coating using a polyester resin as a base paint, or the like in order to prevent corrosion due to rust or the like.

[0031] The body edge 14 of the panel 11 is formed, for example, by welding the horizontal wire member 13 to the outside of the vertical wire member 12 bent in a ring shape. Note that the shape of the tip of the vertical wire member 12 bent as the body edge 14 is not limited to a ring shape and may be appropriately set, and may be, for example, a rectangular shape or the like. Also, the illustrated body edge 14 shows the body edge 14 at the upper part of the panel 11, but the body edge 14 may be formed at the lower part of the panel 11.

[0032] The fence joint 1 is attached to each of a plurality of support columns 16 installed at intervals along the site boundary by bolts 26 and nuts 25, and by fixing both left and right ends of the panel 11 to the support columns 16, a continuous fence having a required length in the width direction can be constructed.

[0033] As shown in FIG. 4, the bolt 26 includes a round head portion 26a and a square root portion 26b having a square cross section at a base close to the round head portion 26a.

[0034] As shown in FIGS. 1 and 2, the fence joint 1 includes a joint body 2 that abuts against the support column 16 and holds the horizontal wire 13, and a fastener 3 that is attached to the joint body 2 and holds the vertical wire 12. Note that the illustrated fence joint 1 is shown attached to the upper part of the support column 16, but the fence joint 1 may be attached to two locations, upper and lower, of the support column 16, or may be appropriately added and attached to the intermediate part according to the size of the panel 11.

[0035] As shown in FIGS. 5 and 6, the joint body 2 is a plate-like member having a longitudinal direction in the width direction of the fence, and includes a fixing portion 5 that abuts against the support column 16, a connecting portion 7 that extends forward in the depth direction from the fixing portion 5, and a side piece portion 6 that extends outward in the width direction of the fence from the connecting portion 7. The joint body 2 is made of a steel plate as an example, and in order to prevent corrosion due to rust or the like, it is preferably subjected to zinc plating or electrostatic powder coating using a polyester resin as a base paint.

[0036] A bolt hole 51 is formed in the substantially central portion of the fixing portion 5. The bolt hole 51 is preferably a rectangular through hole having a side slightly larger than the side of the corner root portion 26b of the bolt 26. In this way, by using the bolt 26 having the corner root portion 26b for fixing the fence joint 1 and making the bolt hole 51 of the fixing portion 5 rectangular, it is possible to prevent the bolt 26 from rotating during tightening with the nut 25.

[0037] As shown in FIG. 4, the connecting portion 7 is formed to extend obliquely forward in the depth direction from the fixing portion 5, and determines the position of the side piece portion 6 in the depth direction with respect to the fixing portion 5. By thus extending the connecting portion 7 obliquely forward in the depth direction from the fixing portion 5, the panel 11 can be attached to the support column 16 so that the position of the panel 11 in the depth direction aligns with the radial center of the support column 16.

[0038] As shown in FIGS. 5 and 6, the side piece portion 6 is formed to extend outward in the width direction of the fence from the connecting portion 7, and includes a hook 61 that holds the horizontal wire 13 and a screw portion 64 for attaching the fastener 3. Note that the extending direction of the side piece portion 6 is not limited to the outside in the width direction of the fence, and may be appropriately set according to the shape of the site boundary portion where the fence is installed, and the left and right side piece portions 6 may extend at different angles in the depth direction respectively.

[0039] As shown in FIG. 7, the hook 61 is formed below the screw portion 64, and includes an inclined portion 61a that inclines from the side piece portion 6 toward the back side in the depth direction, a vertical portion 61b that extends vertically downward from the inclined portion 61a, a horizontal portion 61c that extends horizontally from the lower end of the vertical portion 61b toward the front side in the depth direction, and a stopper portion 61d that extends vertically upward from the front end of the horizontal portion 61c in the depth direction. Further, it is preferable that the hook 61 is formed by bending a part of the side piece portion 6.

[0040] Here, as shown in FIG. 3, since the vertical wire 12 and the horizontal wire 13 are welded so as to overlap each other in the panel 11, the diameter centers of the vertical wire 12 and the horizontal wire 13 do not exist on the same plane, and the horizontal wire 13 is located either on the front side or the back side in the depth direction with respect to the vertical wire 12. For this reason, in order to attach such a panel 11 perpendicular to the ground, as shown in FIG. 3, it is necessary to avoid interference between the horizontal wire 13 and the hook 61 in a state where the vertical wire 12 is in contact with the side piece portion 6. Therefore, it is preferable that the vertical portion 61b and the stopper portion 61d are respectively spaced apart from the side piece portion 6 in the depth direction and arranged at positions where they do not interfere with the horizontal wire 13.

[0041] As described above, when the panel 11 is attached in such a direction that the horizontal wire 13 is located on the back side in the depth direction with respect to the vertical wire 12, the inclination angle of the inclined portion 61a is set so that the vertical portion 61b is at a position where it does not interfere with the horizontal wire 13.

[0042] The horizontal part 61c holds the horizontal wire 13 from below and supports the panel 11. It is preferable that the two horizontal parts 61c arranged on the left and right of the joint body 2 are set so that the panels 11 attached on the left and right are at the same height when attached to the column 16 of the joint body 2. Further, as described above, when the panel 11 is attached in such a direction that the horizontal wire 13 is positioned on the front side in the depth direction with respect to the vertical wire 12, the length in the depth direction of the horizontal part 61c is set so that the stopper part 61d does not interfere with the horizontal wire 13.

[0043] The stopper part 61d extends vertically upward from the front end in the depth direction of the horizontal part 61c. It is preferable that the upper end surface of the stopper part 61d is set to a position higher than the diameter of the horizontal wire 13 that abuts on the horizontal part 61c. By providing such a stopper part 61d, when the panel 11 is temporarily placed by hooking the horizontal wire 13 on the hook 61 during attachment of the panel 11 to the fence joint 1, it is possible to prevent the panel 11 from falling.

[0044] The screw part 64 is, as an example, a bolt having a head 64a and a root part 64b at the base near the head 64a as shown in FIG. 5, and is configured to be attached to the side piece part 6. The head 64a is formed in a circular shape as viewed from the axial direction of the screw part 64, and the root part 64b is formed in a rectangular shape as viewed from the axial direction of the screw part 64. The screw part 64 is attached so as to extend from the side piece part 6 toward the front side in the depth direction through the slit 63 described later. Further, the head 64a is attached so as to be inserted between the side piece part 6 and a bolt fixing claw 62 described later.

[0045] As shown in FIGS. 5 and 6, a slit 63 is formed in the side piece part 6 at a position corresponding to the screw part 64. The slit 63 is set to be slightly wider than the side of the root part 64b formed in a rectangular shape and engages with the root part 64b. Further, a bolt fixing claw 62 is formed on the back side in the depth direction of the slit 63.

[0046] As shown in Fig. 7, the bolt fixing claw 62 includes a support portion 62a that extends horizontally from the lower end of the slit 63 toward the back in the depth direction, and a pressing portion 62b that rises vertically from the end of the support portion 62a on the back side in the depth direction. It is preferable that the bolt fixing claw 62 is formed by bending a part of the side piece portion 6.

[0047] The support portion 62a is formed on a flat surface and supports the side surface of the head portion 64a. The length of the support portion 62a in the depth direction is set so that the head portion 64a and the pressing portion 62b do not interfere when the head portion 64a is inserted between the side piece portion 6 and the pressing portion 62b.

[0048] By inserting the head portion 64a between the pressing portion 62b and the side piece portion 6 in this way, even when a longitudinal force of the screw is applied to the screw portion 64, the head portion 64a abuts against the pressing portion 62b, and the movement of the screw portion 64 in the longitudinal direction of the screw can be restricted. Further, since the root portion 64b is engaged with the slit 63, the rotation of the screw portion 64 around its axis can be restricted.

[0049] Although the screw portion 64 has been described as a bolt having a head portion 64a and a root portion 64b, the screw portion 64 is not limited to this, and it may be a screw directly attached to the side piece portion 6 by welding or the like. In this case, the slit 63 and the bolt fixing claw 62 become unnecessary.

[0050] As shown in Fig. 8, the fastener 3 is a plate-shaped member having the longitudinal direction in the width direction of the fence, and includes a long hole 31 extending in the longitudinal direction of the fastener 3, and claw portions 32 extending toward the back in the depth direction at both ends in the longitudinal direction of the fastener 3. The fastener 3 is made of a steel plate as an example, and it is preferable that zinc plating or electrostatic powder coating using a polyester resin as a base paint is applied to prevent corrosion due to rust or the like.

[0051] The oblong hole 31 has a size in the short side direction larger than the screw diameter of the screw portion 64, and as shown in FIG. 4, in the attached state to the joint body 2, the screw portion 64 is passed through. Further, the oblong hole 31 is formed with a size in the longitudinal direction being a predetermined length so that the fastener 3 can move freely in the width direction of the fence with respect to the joint body 2.

[0052] As shown in FIG. 4, the claw portions 32 extend to a height corresponding to the diameter of the vertical member 12, and the claw portions 32 located at both ends of the fastener 3 are arranged so as to have a wider interval than the interval between adjacent vertical members 12.

[0053] Next, a method of attaching the panel 11 to the support column 16 using such a fence joint 1 will be described.

[0054] First, as shown in FIG. 9, the fixing portion 5 of the joint body 2 is abutted against the support column 16, the bolt 26 is passed through the support column 16 from the bolt hole 51 of the joint body 2, and after passing a washer through the bolt 26, the nut 25 is tightened. Thereby, the joint body 2 is fixed to the support column 16.

[0055] Next, the horizontal member 13 located at a predetermined height of the panel 11 is hooked on the hook 61. At this time, as described above, since the stopper portion 61d set higher than the diameter of the horizontal member 13 is formed on the hook 61, there is no risk of dropping even if the operator releases the panel 11. Also, at this time, when the screw portion 64 is in a state of being detached from the joint body 2, the root portion 64b of the screw portion 64 is engaged with the slit 63 and attached to the side piece portion 6.

[0056] Next, the oblong hole 31 of the fastener 3 is passed through the screw portion 64 protruding between two adjacent vertical members 12, and the fastener 3 is applied to the vertical member 12. At this time, the position of the fastener 3 is adjusted in the width direction of the fence so that two adjacent vertical members 12 are arranged inside the two claw portions 32 formed on the fastener 3 as shown in FIG. 4. Since the oblong hole 31 of the fastener 3 is formed as an oblong hole extending in the width direction of the fence, the position of the fastener 3 in the width direction of the fence can be easily adjusted.

[0057] Next, a washer is passed through the threaded portion 64 and the nut 65 is tightened to fix the retaining fitting 3. At this time, since the base portion 64b of the threaded portion 64 is engaged with the slit 63, the rotation of the threaded portion 64 around its axis is restricted, and the threaded portion 64 cannot rotate around itself when the nut 65 is tightened.

[0058] Thus, according to the fence joint 1 of the present embodiment, when tightening the nut 65, it is not necessary to hold down the rotation of the threaded portion 64 from the opposite side of the panel 11. Therefore, the panel 11 can be attached and detached only by working from one side of the panel 11. Further, since the work can be performed with the panel 11 temporarily placed on the hook 61, an operator can attach and detach the panel 11 alone.

[0059] Also, according to the fence joint 1 of the present embodiment, since the vertical and horizontal members 12 and 13 of the panel 11 are held, the panel 11 can be fixed by one type of fence joint 1 regardless of the shape of the body edge 14. Further, since the left and right panels 11 can be detached independently, maintenance work such as replacement of a part of the panels 11 of the entire fence can be easily performed.

[0060] [Second Embodiment] The fence joint 1 according to the first embodiment described above has the side piece portion 6 and is provided with the joint body 2 characterized in that the threaded portion 64 is attached so as to extend from the side piece portion 6 toward the front side in the depth direction through between the slits 63. Next, a fence joint 1' according to the second embodiment to be described has a joint body 2' having a form different from that of the first embodiment. For members that are the same as or similar to those in the first embodiment described above, the same reference numerals are given and detailed description thereof is omitted.

[0061] FIG. 10 is a perspective view seen from the back side in the depth direction showing one form of a fence configured using a fence joint according to the second embodiment of the present invention. FIG. 11 is a perspective view seen from the front side in the depth direction showing a joint body of the fence joint according to the second embodiment of the present invention. FIG. 12 is a perspective view seen from the back side in the depth direction showing a joint body of the fence joint according to the first embodiment of the present invention. FIG. 13 is a sectional view taken along line D-D of FIG. 11.

[0062] As shown in FIG. 10, the fence joint 1' according to the present embodiment is attached to the support column 16 and fixes the panel 11 to the support column 16.

[0063] The fence joint 1' is attached to a plurality of support columns 16 installed at intervals along the site boundary by bolts 26 and nuts 25 respectively, and by fixing the left and right end portions of the panel 11 to the support columns 16, a continuous fence having a required length in the width direction can be constructed. Further, as shown in FIG. 10, the fence joint 1' includes a joint body 2' that abuts against the support column 16 and holds the horizontal member 13, and a fastener 3 that is attached to the joint body 2 and holds the vertical member 12.

[0064] As shown in FIGS. 11 and 12, the joint body 2' is a plate-like member having the longitudinal direction in the width direction of the fence, and has a fixing portion 5 that abuts against the support column 16, a connecting portion 7 that extends from the fixing portion 5 to the front side in the depth direction, and a side piece portion 6' that extends from the connecting portion 7 to the outside in the width direction of the fence. The joint body 2' is made of a steel plate as an example, and in order to prevent corrosion due to rust or the like, it is preferably subjected to zinc plating or electrostatic powder coating using a polyester resin as a base paint.

[0065] As shown in FIGS. 11 and 12, the side piece portion 6' is formed to extend from the connecting portion 7 to the outside in the width direction of the fence, and includes a hook 61 that holds the horizontal member 13 and a screw portion 64 to which the fastener 3 is attached. Note that the extending direction of the side piece portion 6' is not limited to the outside in the width direction of the fence, and may be appropriately set according to the shape of the site boundary where the fence is installed, and the left and right side piece portions 6' may extend at different angles in the depth direction.

[0066] In addition, a bolt engaging portion 66 is formed at a position corresponding to the screw portion 64 on the side piece portion 6'. The bolt engaging portion 66 has a hole portion 66a and a groove portion 66b formed at the lower portion of the hole portion 66a.

[0067] The hole portion 66a is a through hole formed in the middle portion in the vertical direction of the side piece portion 6'. As an example, it is formed in a substantially semi-circular shape having a diameter larger than the diameter of the head portion 64a formed in a circular shape when viewed from the axial direction of the screw portion 64.

[0068] The groove portion 66b is formed at the lower portion of the hole portion 66a and is a through hole formed in a substantially rectangular shape as an example, and engages with the root portion 64b of the screw portion 64.

[0069] In addition, a bolt pressing portion 67 is formed on the inner side in the depth direction of the bolt engaging portion 66.

[0070] As shown in FIGS. 12 and 13, the bolt pressing portion 67 includes a base portion 67a that is continuous with the side piece portion 6' and protrudes toward the inner side in the depth direction to be formed in a substantially hemispherical shape, and a pressing claw 67b that extends downward from the base portion 67a.

[0071] As an example, it is preferable that the bolt pressing portion 67 is formed simultaneously when the bolt engaging portion 66 is formed by pressing. That is, it is preferable that the base portion 67a and the pressing claw 67b are formed by pushing the portions corresponding to the hole portion 66a and the groove portion 66b toward the inner side in the depth direction without completely cutting them out from the side piece portion 6'.

[0072] Although the case where the hole portion 66a is formed in a substantially semi-circular shape and the base portion 67a is formed in a substantially hemispherical shape has been described, the shapes of the hole portion 66a and the base portion 67a are not limited thereto, and may be, for example, substantially rectangular.

[0073] The threaded portion 64 is attached by passing the head portion 64a through the hole portion 66a and then engaging the root portion 64b with the groove portion 66b. At this time, as shown in FIG. 13, the threaded portion 64 extends from the side piece portion 6' toward the front side in the depth direction, and the head portion 64a is attached so as to be inserted between the side piece portion 6' and the pressing claw 6 7b.

[0074] By inserting the head portion 64a between the pressing claw 67b and the side piece portion 6' in this way, even if a longitudinal force of the screw is applied to the threaded portion 64, the head portion 64a abuts against the pressing claw 67b, and the movement of the threaded portion 64 in the longitudinal direction of the screw can be restricted. Further, since the root portion 64b is engaged with the groove portion 66b, the rotation of the threaded portion 64 around its axis can be restricted.

[0075] Further, since the bolt engaging portion 66 according to the present embodiment is formed in the middle portion of the side piece portion 6', the upper side edge of the side piece portion 6' has a shape that is continuous without notches such as slits. Therefore, the side piece portion 6' has a shape excellent in strength, and even when a large load is applied to the hook 61, deformation of the side piece portion 6' can be prevented.

[0076] In addition, in this embodiment, the fence joints 1 and 1' are provided with side piece portions 6 on both sides with respect to the fixing portion 5, and the case where the panel 11 is attached to the left and right of the support column 16 has been described. However, the shape of the fence joints 1 and 1' is not limited to this, and it may be formed to have a side piece portion 6 only on one side with respect to the fixing portion 5 and attach the panel 11 to either the left or the right of the support column 16. Further, in order to improve the strength without changing the plate thickness, ribs 71 protruding toward the back side in the depth direction may be formed in the fixing portion 5, the side piece portions 6 and 6', and the connecting portion 7 as needed, as shown in an example in FIG. 14. The ribs 71 are preferably formed by so-called embossing, which is performed by extruding a part of the fixing portion 5, the side piece portions 6 and 6', and the connecting portion 7. Further, a plurality of ribs 71 may be formed at intervals in the vertical direction. In addition, the case where the head portion 64a is formed in a circular shape as viewed from the axial direction of the screw portion 64 has been described. However, the shape of the head portion 64a is not limited to this, and it may be, for example, a polygon. Further, as an example, the case where the base portion 64b is formed in a rectangular shape as viewed from the axial direction of the screw portion 64 has been described. However, the shape of the base portion 64b is not limited to this, and any shape that can engage with the slit 63 or the groove portion 66b may be used. For example, a shape having a protrusion or the like may be used. It is clear from the description of the claims that forms with such modifications or improvements added may also be included in the technical scope of the present invention.
