[0001] The present invention relates to a mounting member for a fence, and more particularly to a mounting member for a fence for connecting and fixing adjacent fence members to each other.

Background Art

[0002] Generally, a fence constructed along the site boundary is formed by continuously installing fence members along columns erected at a predetermined interval, and adjacent fence members are connected and fixed to each other using a mounting member for a fence.

[0003] Such mounting members for fences are known in various configurations. For example, the mounting member for a fence described in Patent Document 1 includes a horizontal bar locking tool and a vertical bar locking tool that are detachably connected to each other. The horizontal bar locking tool includes a locking portion that is locked to a horizontal bar at one end of an adjacent mesh fence, and a connection portion that is connected to the locking portion and connected to the vertical bar locking tool. The vertical bar locking tool includes a vertical bar fitting portion that fits a vertical bar at one end of an adjacent mesh fence, and a connection receiving portion that is connected to the vertical bar fitting portion and connects the connection portion of the horizontal bar locking tool. The connection receiving portion and the connection portion are connected to connect the horizontal bar locking tool and the vertical bar locking tool, and the locking portion is rotated around the horizontal bar while being locked to the horizontal bar so that the vertical bar is fitted into the vertical bar fitting portion.

Patent Document 1

[0005] Another example of a fence mounting member is shown in Figure 8, which includes a first fitting 101 and a second fitting 102 that clamp onto the fence surface of the fence member 100 from the front and back, respectively. The vertical wires 3 and horizontal wires 4 are clamped by the vertical wire holding parts 104 and horizontal wire holding parts 105 formed on the first fitting 101 and the second fitting 102, respectively, and the fence member is connected by combining the first fitting 101 and the second fitting 102 with a bolt 103. [Overview of the project] [Problems that the invention aims to solve]

[0006] However, conventional fence mounting components use bolts 103 to fix the first fitting 101 and the second fitting 102, as described above. However, these bolts 103 are small, around M6 size, which poses a problem as it makes the bolt fastening process cumbersome. Furthermore, because such small bolts are used, they are frequently lost, causing stress for workers during installation. In addition, depending on the fence installation environment, it may be difficult or impossible to insert the bolts 103 through the through-holes of the first fitting 101 and tighten them using tools.

[0007] Furthermore, the first fitting 101 and the second fitting 102 are parts formed by bending metal plates using sheet metal, which made it difficult to temporarily place them on the fence surface when fastening the bolts 103, and posed a problem as they had to be held in place by the worker at all times.

[0008] Furthermore, the fact that the first fitting 101 and the second fitting 102 are composed of two parts, and that bolts 103 are used, made it difficult to reduce costs. In addition, extra spare bolts are supplied to account for potential bolt loss, which also contributes to the difficulty in reducing costs.

[0009] Therefore, the present invention has been made in view of the above matters, and aims to provide a fence mounting member that allows for easy connection of adjacent fence members without the need for bolt fastening, and that reduces the number of parts and thus the cost. [Means for solving the problem]

[0010] The fence mounting member according to the present invention is a fence mounting member for connecting adjacent fence members when fence members having a fence surface formed by joining a plurality of vertical members and a plurality of horizontal members in a grid pattern are installed continuously along posts erected at predetermined intervals, comprising a first main body assembled from the surface of the fence surface and a second main body assembled from the back of the fence surface, wherein the first main body and the second main body are connected by a bendable connecting portion, and the first main body, the second main body and the connecting portion are integrally formed.

[0011] In the fence mounting member according to the present invention, it is preferable that a screw shaft is erected on either the first main body or the second main body, and that a screw shaft engagement portion is formed on the other of the first main body or the second main body, with which the screw shaft engages.

[0012] In the mounting member for a fence according to the present invention, the screw shaft engaging portion preferably comprises a plurality of engaging claws arranged radially.

[0013] In the fence mounting member according to the present invention, it is preferable that a transverse wire holding groove extending in the direction of extension of the transverse wire is formed in at least one of the first main body portion or the second main body portion.

[0014] In the fence mounting member according to the present invention, a locking projection is erected on at least one of the first main body portion or the second main body portion, and it is preferable that the distance between the connecting portion and the locking projection in the direction of extension of the horizontal wire is greater than the distance between the vertical wires at adjacent ends of adjacent fence members.

[0015] The above summary of the invention does not enumerate all the features necessary for the present invention, and subcombinations of these features may also constitute an invention. [Effects of the Invention]

[0016] According to the present invention, fence members can be assembled without using bolts for connection, making the connection work easier. Furthermore, because the fence mounting member is composed of a single part, the present invention can reduce costs and eliminate the complexity of parts management.

[0020] As shown in FIG. 1, the fence mounting member 8 according to the present embodiment is used for constructing the fence 7 and is a member for connecting adjacent fence members 2 to each other when the fence members 2 are continuously installed along the columns 1 erected at predetermined intervals.

[0021] As an example, the column 1 is made of a round pipe-shaped steel pipe, and the lower end portion is buried in a foundation such as mortar and erected on the ground. Also, a plurality of columns 1 are installed at predetermined intervals along the site boundary portion. Note that the column 1 is not limited to a round pipe-shaped steel pipe, and may be a pipe having 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 column 1 is not limited to burying it in a foundation such as mortar, and it may be erected by a conventionally well-known method such as directly driving the column 1 into the ground surface or installing a base plate on a concrete surface or the like and then erecting it.

[0022] The fence member 2 comprises a fence surface 5 formed by joining multiple vertical wires 3 and multiple horizontal wires 4 to each other in a grid pattern, and a furring strip 6 positioned at the upper end of the fence surface 5. The furring strip 6 is integrally formed with the fence surface 5, and after joining the vertical wires 3 and horizontal wires 4 in a grid pattern, the upper end of the fence surface 5 is bent into a roughly circular shape to form a cylindrical shape. The shape of the furring strip 6 is not limited to a cylindrical shape and may be set as appropriate; for example, it may be a rectangular shape. Furthermore, although the case where the furring strip 6 is formed at the upper end of the fence surface 5 has been described, the furring strip 6 may also be formed at the lower end of the fence surface 5. The horizontal wires 4 may be joined to the inner circumference of the circular part, or to the outer circumference of the circular part.

[0023] The vertical wires 3 and horizontal wires 4 are, for example, made of iron wire, and their respective intersections arranged in a grid pattern are joined by welding. It is preferable that the vertical wires 3 and horizontal wires 4 be coated with zinc plating or electrostatic powder coating using polyester resin as a base coat to prevent corrosion due to rust, etc. Furthermore, in this specification, the surface of the fence surface 5 is defined as the side where the vertical wires 3 protrude more than the horizontal wires 4, as shown in Figure 2, and the back surface of the fence surface 5 is defined as the side where the horizontal wires 4 protrude more than the vertical wires 3.

[0024] As shown in Figure 2, the fence mounting member 8 according to this embodiment connects the intermediate portion of the fence surface 5, and connects adjacent fence members 2 by clamping the adjacent ends of adjacent fence members 2 from the front and back sides of the fence surface 5.

[0025] As shown in Figure 3, the fence mounting member 8 according to this embodiment comprises a substantially rectangular plate-shaped mounting member body 9 and a screw member 40. The fence mounting member 8 according to this embodiment is arranged so that the left-right direction is parallel to the horizontal wire 4 and the up-down direction is parallel to the vertical wire in the view of Figure 3.

[0026] The mounting member body 9 comprises a first main body portion 10 and a second main body portion 20, as well as a connecting portion 30 that connects the first main body portion 10 and the second main body portion 20. The mounting member body 9 is, for example, made by press-forming a metal plate such as a steel plate or a stainless steel plate, and the first main body portion 10, the second main body portion 20, and the connecting portion 30 are integrally formed. Furthermore, the mounting member body 9 may be coated with zinc plating or electrostatic powder coating using polyester resin as a base paint to prevent corrosion due to rust, etc.

[0027] The first main body portion 10 is formed in the shape of a rectangular plate with its length in the left-right direction. The upper edge of the first main body portion 10 is integrally formed with a connecting portion 30 having a predetermined width dimension H so as to extend toward the adjacent second main body portion 20.

[0028] Furthermore, the first main body portion 10 includes a through hole 11 that penetrates in the thickness direction of the plate and a locking projection 13 that rises from the plate-like plane.

[0029] As shown in Figure 4, the through-hole 11 is a through-hole for attaching the screw member 40. The through-hole 11 is formed approximately in the center of the first main body portion 10 in the left-right direction and below the center in the up-down direction. Furthermore, as shown in Figure 5, it is preferable that the through-hole 11 be formed in a substantially rectangular shape to correspond to the shape of the base portion 43 of the screw member 40, which will be described later.

[0030] The locking projection 13 restricts the movement of the horizontal wire 4 of the fence mounting member 8 in the extending direction when it is attached to the fence surface 5. The locking projection 13 is formed on the side edge of the first main body 10, on the side opposite to the side adjacent to the second main body 20, that is, on the side edge that is on the outside in the left-right direction of the mounting member body 9. For example, the locking projection 13 is a substantially rectangular piece formed by bending a part of the side edge of the first main body 10, and is formed to stand upright in the same direction as the screw shaft 41 of the screw member 40, which will be described later, protrudes. For example, it is preferable that the locking projection 13 be formed near the lower end of the first main body 10.

[0031] The second main body portion 20 is formed in the shape of a rectangular plate with its length in the left-right direction. The upper edge of the second main body portion 20 is integrally formed with a connecting portion 30 having a predetermined width dimension H so as to extend toward the adjacent first main body portion 10.

[0032] Furthermore, the second main body portion 20 includes a screw shaft engagement portion 21 that penetrates in the plate thickness direction, a locking projection portion 23 that rises from the plate-like plane, and a transverse wire holding groove 24 formed along the extending direction of the transverse wire 4.

[0033] The screw shaft engaging portion 21 engages with the screw shaft 41 of the screw member 40 when it is attached to the fence surface 5. The screw shaft engaging portion 21 is formed approximately in the left-right center of the second main body portion 20 and below the center in the vertical direction. Furthermore, when the connecting portion 30 is bent so that the first main body portion 10 and the second main body portion 20 overlap, the screw shaft engaging portion 21 is formed at a position corresponding to the through hole 11 of the first main body portion 10. The screw shaft engaging portion 21 is a hole that penetrates the planar second main body portion 20, and the periphery of the hole is provided with a plurality of engaging claws 22 arranged radially.

[0034] As shown in Figure 6, the engaging claw 22 is formed to be inclined and erect in the opposite direction to the direction in which the screw shaft 41 of the screw member 40, which will be described later, protrudes. Preferably, the screw shaft engaging portion 21 is formed by punching out a part of the second main body portion 20, and the engaging claw 22 is formed by bending a part of the second main body portion 20.

[0035] The locking projection 23 restricts the movement of the horizontal wire 4 of the fence mounting member 8 in the extending direction when it is attached to the fence surface 5. The locking projection 23 is formed on the side edge of the second main body 20, on the side opposite to the side adjacent to the first main body 10, that is, on the side edge that is on the outside in the left-right direction of the mounting member body 9. For example, the locking projection 23 is a substantially rectangular piece formed by bending a part of the side edge of the second main body 20, and is formed to stand upright in the same direction as the direction in which the screw shaft 41 of the screw member 40, which will be described later, protrudes. The locking projection 23 is formed at a different position in the vertical direction from the locking projection 13 provided on the first main body 10.

[0036] The horizontal wire retaining groove 24 engages with the horizontal wire 4 when attached to the fence surface 5, preventing the fence mounting member 8 from rotating. As shown in Figure 3, the horizontal wire retaining groove 24 is formed above the vertical center of the second main body portion 20. The horizontal wire retaining groove 24 is a groove that extends linearly in the left-right direction in view of Figure 3, and is formed to open in the same direction as the screw shaft 41 of the screw member 40, which will be described later, protrudes. Preferably, the horizontal wire retaining groove 24 is formed by bending a part of the flat plate-shaped second main body portion 20 so that its cross-sectional shape is approximately V-shaped.

[0037] As shown in Figure 3, the connecting portion 30 connects the first main body portion 10 and the second main body portion 20 in the left-right direction. The connecting portion 30 connects the upper ends of the first main body portion 10 and the second main body portion 20 with a predetermined width dimension H. In addition, to facilitate bending, the connecting portion 30 may have a portion of its thickness thinned, or may be processed with folds, grooves, or cuts to mark the bending points.

[0038] Between the first main body portion 10 and the second main body portion 20, a deep groove 31 with a predetermined depth dimension D and groove width dimension W is formed by a connecting portion 30. The width dimension H of the connecting portion 30 is formed to be sufficiently smaller than the depth dimension D of the deep groove 31. Furthermore, it is preferable that the groove width dimension W is formed to be larger than the wire diameter of the transverse wire 4.

[0039] As shown in Figure 4, the screw member 40 comprises a screw shaft 41, a head 42, and a base portion 43.

[0040] The screw shaft 41, for example, has a coarse-pitch helical thread and groove, and is formed in the same way as the screw shaft of a so-called tapping screw. The tip of the screw shaft 41 is preferably tapered or hemispherical. In this embodiment, the groove of the screw shaft 41 is not a helical groove, but a closed groove around the axis, and may be a series of grooves formed in the axial direction. Furthermore, the thread of the screw shaft 41 preferably has a bevel formed at an angle corresponding to the engaging claw 22 of the screw shaft engaging portion 21.

[0041] For example, the head 42 is formed such that, when viewed from the axial direction of the screw shaft 41, it is circular and larger than the through hole 11 of the first body portion 10.

[0042] The root portion 43 is the base of the screw shaft 41, which is close to the head portion 42, and its shape, when viewed from the axial direction of the screw shaft 41, is formed as a rectangle corresponding to the through hole 11 of the first main body portion 10.

[0043] As shown in Figure 5, the screw member 40 is inserted through the through hole 11 of the first main body 10, and is attached so that the screw shaft 41 protrudes from the flat plate-shaped first main body 10. Furthermore, it is preferable that the base portion 43 of the screw member 40 is firmly fixed to the first main body 10 by crimping or the like.

[0044] Although the screw member 40 has been described as being attached to the first main body 10 as a bolt-shaped member having a head 42, the screw member 40 in this embodiment is not limited to this, and may be attached by welding or the like so that only the screw shaft 41 is erected on the flat plate-shaped first main body 10.

[0045] Next, a method for connecting fence members using the fence mounting member 8 according to this embodiment will be described.

[0046] First, as shown in Figure 7, the fence mounting member 8 is inserted between the vertical wire 3 located at the adjacent end of one of the adjacent fence members 2 and the second vertical wire 3 from the adjacent end. At this time, the orientation of the fence mounting member 8 is aligned and inserted so that the second main body 20, which has a horizontal wire holding groove 24, is located on the back side of the fence surface 5 where the horizontal wires 4 protrude more than the vertical wires 3.

[0047] Next, the fence mounting member 8 is positioned so that it straddles the horizontal wire 4 in the deep groove 31 and contacts the horizontal wire 4 with the connecting portion 30. Since the depth dimension D of the deep groove 31 is formed to be sufficiently deep relative to the outer dimensions in the short direction of the first main body 10 and the second main body 20, the fence mounting member 8 can be hooked onto the horizontal wire 4, and will not fall even if the worker releases their hand from the fence mounting member 8, allowing the fence construction work to be carried out efficiently.

[0048] Next, with the transverse wire 4 in contact with the transverse wire holding groove 24, the connecting portion 30 is bent. The bending of the connecting portion 30 is such that the screw shaft 41 protruding from the first main body portion 10 moves toward the second main body portion 20, and the first main body portion 10 and the second main body portion 20 are overlapped. The width dimension H of the connecting portion 30 is sufficiently small compared to the outer dimensions in the short direction of the first main body portion 10 and the second main body portion 20, and it has been processed to facilitate bending, so that the worker can easily bend the connecting portion 30 with their fingers without using any tools.

[0049] When the connecting portion 30 is bent, the screw shaft 41 is inserted into the screw shaft engaging portion 21. The tip of the screw shaft 41 is formed in a tapered shape, and the engaging claws 22 of the screw shaft engaging portion 21 are formed at an angle. Therefore, if an operator holds the first main body portion 10 and the second main body portion 20 between their fingers, the screw shaft 41 can be easily pushed into the screw shaft engaging portion 21.

[0050] The screw shaft 41, inserted into the screw shaft engagement portion 21, has its screw groove engage with the engagement claw 22, restricting its movement in the pulling direction. Furthermore, the rectangular base portion 43 of the screw member 40 is fitted into the correspondingly shaped through hole 11, and is firmly attached to the first main body portion 10 by crimping or the like. Therefore, even if the fence member 2 of the completed fence 7 vibrates due to the influence of the installation environment, the screw shaft 41 will not rotate and fall out of the screw shaft engagement portion 21.

[0051] Furthermore, the fence mounting member 8 is positioned such that the locking projections 13 and 23 are located between the vertical wire 3 at the adjacent end of the other fence member 2 and the second vertical wire 3 from the adjacent end. Since the locking projections 13 and 23 are formed at different positions in the vertical direction, the locking projections 13 and 23 do not interfere with each other even when the connecting portion 30 is bent to overlap the first main body portion 10 and the second main body portion 20.

[0052] Furthermore, the connecting portion 30, in its bent state, is positioned between the vertical wire 3 located at the adjacent end of one of the fence members 2 and the second vertical wire 3 located from the adjacent end.

[0053] In other words, the locking projections 13, 23 and the connecting portion 30 are formed such that the spacing between the horizontal wires 4 in the extending direction is greater than the spacing between the vertical wires 3, 3 at the adjacent ends of adjacent fence members 2, 2. With these locking projections 13, 23 and connecting portion 30, even if a force is applied to separate adjacent fence members 2, 2, the vertical wires 3, 3 located at the adjacent ends will come into contact with the locking projections 13, 23 or the connecting portion 30, thereby maintaining an appropriate gap between the fence members 2, 2.

[0054] As described above, the fence mounting member 8 according to this embodiment allows adjacent fence members 2, 2 to be connected without the need for bolt fastening or other operations using tools, thus making the connection work easier. Furthermore, since the fence mounting member 8 is composed of a single part, the complexity of parts management is eliminated and costs can be reduced.

[0055] Furthermore, according to the fence mounting member 8 of this embodiment, the deep groove 31 can be hooked onto the horizontal wire 4 to prevent the fence mounting member 8 from falling, thereby reducing the burden on the worker when connecting the fence members 2.

[0056] In this embodiment, the fence mounting member 8 has been described in the case where the horizontal wire retaining groove 24 is formed in the second main body portion 20. However, the horizontal wire retaining groove 24 may also be formed in the first main body portion 10, or in both the first main body portion 10 and the second main body portion 20. Furthermore, the horizontal wire retaining groove 24 has been described in the case where the second main body portion 20 is bent to have a substantially V-shaped cross-section. However, the horizontal wire retaining groove 24 may also be formed by bending the second main body portion 20 to have an arc-shaped cross-section. It is clear from the description of the claims that such modified or improved forms may also be included in the technical scope of the present invention. [Explanation of Symbols]
