Description

[Technical field]

[0001] The present invention relates to a furring strip used for fences and the like. [Background technology]

[0002] Generally, fences installed along property boundaries are constructed by stretching multiple furring strips made of angle bars or similar between posts erected at intervals into the ground, and then stretching a net over the furring strips. Also, if the total length of one furring strip is shorter than the installed length of the fence, the fence is constructed by connecting multiple furring strips lengthwise.

[0003] As shown in Figure 13, conventional furring strips are connected by butting the end faces of two adjacent furring strips together and tightening multiple bolts and nuts via a joint piece having a side length shorter than the side length of the furring strips.

[0004] Furthermore, Patent Document 1 describes an angle bar connection structure for fence furring strips, etc., which can simplify the work of aligning the bolt holes of two adjacent furring strips when connecting the furring strips, and ensures the straightness of the furring strips after connection and a fastening ability without any rattling.

[0005] [Patent Document 1] Patent No. 2878981 Summary of the Invention [Problem to be solved by the invention]

[0006] The angle bar connection structure for fence furring strips and the like shown in Patent Document 1 reduces the labor required for fence installation work by engaging an engaging bent piece provided on one angle bar with a drilled hole provided on the other angle bar, and also makes it possible to reduce the number of bolts required for connection. However, although the angle bar connection structure for fence furring strips and the like shown in Patent Document 1 can reduce the number of bolts, it still uses bolts and nuts at the connecting parts and requires the use of tools for the connection work, so there has been a demand for further simplification of the work.

[0007] Furthermore, in the case of a temporary fence that is installed temporarily and is to be removed, not only ease of assembly but also ease of disassembly is required.

[0008] Therefore, the present invention has been made in consideration of the above-mentioned points, and its object is to provide a furring strip for a fence that allows connection using only the furring strip, without using fastening parts such as joint pieces or bolts and nuts, and that makes it easy to assemble and disassemble the fence.

[Figure 13] A reference perspective view showing a conventional method for connecting fencing furring strips DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and all of the combinations of features described in the embodiments are not necessarily essential to the solution of the invention.

[0022] Fig. 1 is a reference diagram showing one form of a fence installed using fence furring strips according to this embodiment, and Fig. 2 is a reference perspective view showing the entire first furring strip and second furring strip according to this embodiment. In this specification, the leading end and trailing end in the longitudinal direction are defined as the directions of the arrows shown in Fig. 2. In this specification, the height direction, width direction, and the inside and outside of the fence furring strip are defined as the directions of the arrows shown in Fig. 2. In this specification, the front view, back view, and plan view of the fence furring strip are defined as views seen from the directions of the arrows shown in Fig. 2.

[0023] As shown in Figure 1, the fence furring strip 1 of this embodiment is installed between posts 2 spaced apart and erected on the ground at a height that will define the upper and lower edges of the fence 100, and fixes the net 3.

[0024] As shown in Fig. 1 as an example, the posts 2 include a main post 2a with net 3 on both sides of the post and a substantially V-shaped cross section, and an end post 2b with net 3 on one side of the post and a substantially L-shaped cross section. The main post 2a and the end post 2b are both formed from general structural rolled steel material, for example. Furthermore, the main post 2a and the end post 2b are provided with through holes for passing bolts at the heights that become the upper and lower edges of the fence 100, and the fence furring strip 1 is mounted on the posts 2 by bolts that pass through the through holes and fasteners (not shown).

[0025] As an example, the net 3 is a wire mesh made of iron wire that is processed into a series of peaks and woven together to form a diamond-shaped mesh. The mesh joints are not fixed by welding or the like, so they have shock absorption properties. As shown in Figure 12, the net 3 has iron wire 54 threaded through the edges at the top and bottom, and is attached by hooking the iron wire 54 onto the net claws 51 of the fence furring strip 1, which will be described later.

[0026] As shown in FIG. 3, the fence furring strips 1 are formed by longitudinally connecting the leading end (one end in the claims) of the first furring strip 1a and the rear end (the other end in the claims) of the second furring strip 1b, which are adjacent fence furring strips. FIG. 4 is a perspective view showing the state before the first furring strip 1a and the second furring strip 1b are connected. In this embodiment, the leading end of the first furring strip 1a and the leading end of the second furring strip 1b have the same shape, and the rear end of the first furring strip 1a and the rear end of the second furring strip 1b also have the same shape. Therefore, the first furring strip 1a and the second furring strip 1b can be continuously connected in the longitudinal direction to form a continuous furring strip of the required length.

[0027] As shown in FIG. 4, the first furring strip 1a and the second furring strip 1b are long parts having a cross-sectional shape of an approximately L-shape with side lengths A and B and a plate thickness t, and are set to arbitrary lengths L1 and L2. As an example, the first furring strip 1a and the second furring strip 1b are formed from general structural rolled steel material, etc., and are preferably subjected to zinc plating or electrostatic powder coating using polyester resin as a base paint to prevent corrosion due to rust, etc. In this specification, the sides of the first furring strip 1a and the second furring strip 1b are referred to as horizontal sides 10a and 10b, and vertical sides 20a and 20b, depending on the mounting position to the fence 100. In this embodiment, it is preferable that the side length A of the horizontal sides 10a and 10b and the side length B of the vertical sides 20a and 20b are the same length. In the following explanation, the fence furring strip 1 is attached to the upper edge of a fence 100 as shown in FIG.

[0028] Figure 5(a) is a front view of a fence furring strip according to this embodiment, seen from the outside in the width direction of the furring strip, showing the state before adjacent furring strips are connected, and Figure 5(b) is a plan view of the furring strip seen from the outside in the height direction.

[0029] 5(a) and 5(b), the horizontal side 10a and the vertical side 20a are recessed inward at the tip of the first furring strip 1a, and a drawn portion 12 is formed, which is made up of a horizontal surface approximately parallel to the horizontal side 10a and a vertical surface approximately parallel to the vertical side 20a. The outer surface of the drawn portion 12 is smoothly connected by a tapered portion 11 to the outer surfaces of the horizontal side 10a and the vertical side 20a, which are not recessed inward.

[0030] When the first barrel edge 1a and the second barrel edge 1b are connected, the outer surface of the aperture part 12 abuts against the inner surface of the rear end part of the second barrel edge 1b. When the first barrel edge 1a and the second barrel edge 1b are connected, as shown in FIGS. 5(a) and 5(b), if the horizontal side 10a and the horizontal side 10b are located in the same virtual plane F and the vertical side 20a and the vertical side 20b are located in the same virtual plane G, the straightness of the barrel edge 1 for the fence after connection can be maintained and the aesthetic appearance will not be impaired. Therefore, it is preferable that the aperture part 12 is formed such that its outer surface is recessed inward by a plate thickness t from the outer surfaces of the horizontal side 10a and the vertical side 20a.

[0031] On both sides of the aperture part 12, that is, on both the horizontal plane and the vertical plane, connection claws 13 that engage with the first hole part 31 and the second hole part 41 of the second barrel edge 1b, which will be described later, are formed one by one. The connection claw 13 formed on the horizontal plane and the connection claw 13 formed on the vertical plane are formed at the same position in the longitudinal direction and have the same shape.

[0032] As shown in FIGS. 5(a) and 5(b), the connection claw 13 includes a rising part 14 that protrudes outward from the aperture part 12, and an engaging part 15 that is substantially parallel to the horizontal plane or the vertical plane of the aperture part 12 and extends in the longitudinal direction from the rising part 14, and is formed in a substantially L-shaped configuration. In the present embodiment, the connection claw 13 has the rising part 14 located on the tip side of the first barrel edge 1a and an engaging part 15 that extends from the rising part 14 toward the rear end side. Further, the connection claw 13 is formed, for example, by shearing a part of the aperture part 12 by press working and plastically deforming it.

[0033] The surface of the rising part 14 that faces the inside of the engaging part 15 is formed so as to be separated from the outer surface of the aperture part 12 by at least the plate thickness t and by a distance necessary to sandwich the side edge of the second barrel edge 1b. As shown in FIGS. 5(a) and 5(b), the rising part 14 may be formed to be inclined with respect to the horizontal side 10a or the vertical side 20a, or may be formed to be perpendicular to the horizontal side 10a or the vertical side 20a.

[0034] When the first furring strip 1a and the second furring strip 1b are connected, the engaging portion 15, together with the outer surface of the drawn portion 12, holds the horizontal edge 10b and the vertical edge 20b at the rear end of the second furring strip 1b. The engaging portion 15 has a constant size in a direction intersecting the longitudinal direction (hereinafter referred to as the width of the engaging portion 15) and is formed so as to continue from the rising portion 14. In this specification, the width of the engaging portion 15 is defined as dimension C. The size from the outer surface of the drawn portion 12 to the outer surface of the engaging portion 15 (hereinafter referred to as the height of the engaging portion 15) is defined as dimension E.

[0035] At the rear end of the second furring strip 1b, as shown in Figs. 5(a) and 5(b), a first hole 31 is formed in the horizontal side 10b and a second hole 41 is formed in the vertical side 20b.

[0036] As shown in FIG. 5(b), the first hole 31 is a through hole formed in a substantially rectangular shape extending in the longitudinal direction, and the size in the width direction of the second furring strip 1b (hereinafter referred to as the width of the first hole 31) is set to be at least larger than the width dimension C of the engagement portion 15 so that the connecting claw portion 13 can be inserted therethrough. In this specification, the width of the first hole 31 is defined as the dimension C'. In addition, the width dimension C' of the first hole 31 is preferably formed so that the gap in the width direction between the first hole 31 and the connecting claw portion 13 during connection is as small as possible in order to suppress rattling after the first furring strip 1a and the second furring strip 1b are connected. In addition, the position in the width direction of the second furring strip 1b where the first hole 31 is formed is preferably a position corresponding to the connecting claw portion 13 so that the vertical side 20a and the vertical side 20b are located in the same imaginary plane when the first furring strip 1a and the second furring strip 1b are connected.

[0037] As shown in FIG. 5(a), the second hole 41 is a through hole formed in a substantially rectangular shape extending in the longitudinal direction, and the height dimension of the second furring strip 1b (hereinafter referred to as the width of the second hole 41) is set to be greater than at least the sum of the width dimension C of the engaging portion 15 and the height dimension E of the engaging portion 15. In this specification, the width of the second hole 41 is dimension D. The second hole 41 is formed in the same position as the first hole 31 in the longitudinal direction and has the same longitudinal size. In addition, the height position of the second furring strip 1b where the second hole 41 is formed is preferably a position corresponding to the connecting claw portion 13 so that the horizontal side 10a and the horizontal side 10b are located in the same imaginary plane when the first furring strip 1a and the second furring strip 1b are connected.

[0038] Next, the shape of the fence furring strip 1 other than the connecting portions in this embodiment will be described.

[0039] As shown in FIG. 2, a plurality of net claw portions 51 protruding toward the inside in the width direction are formed at regular intervals on the vertical edge 20a of the first furring strip 1a and the vertical edge 20b of the second furring strip 1b.

[0040] 6, the net claw portion 51 has rising portions 52 that protrude inward in the width direction from the inner surfaces of the vertical sides 20a, 20b, and engagement portions 53 that extend in the direction of the horizontal sides 10a, 10b from the rising portions 52. The net claw portion 51 is formed by shearing and plastically deforming parts of the vertical sides 20a, 20b, for example, by press working.

[0041] The rising portion 52 is formed such that the surface of the engaging portion 53 facing outward in the width direction is separated from the inner surfaces of the vertical sides 20a, 20b by a distance necessary for bridging the iron wire 54 for attaching the net 3. In this specification, the distance between the surface of the engaging portion 53 facing outward in the width direction and the inner surfaces of the vertical sides 20a, 20b is defined as dimension S1. Therefore, the dimension S1 is formed to be larger than the wire diameter of the iron wire 54. Moreover, the rising portion 52 may be formed to be inclined with respect to the vertical sides 20a, 20b as shown in FIG. 6, or may be formed to be perpendicular to the vertical sides 20a, 20b.

[0042] When attaching the net 3, the iron wire 54 passes between the engagement portion 53 and the inner surfaces of the horizontal sides 10a and 10b. Therefore, in order to prevent the iron wire 54 from being damaged, it is preferable that the engagement portion 53 is formed so that the tip portion has a semicircular shape, as shown in FIG. 5(a). In this specification, the distance from the tip portion of the engagement portion 53 to the inner surfaces of the horizontal sides 10a and 10b is defined as dimension S2, as shown in FIG. 6. Dimension S2 is larger than the wire diameter of the iron wire 54 for attaching the net 3, and is formed so as to be a distance sufficient to allow the iron wire 54 to pass through.

[0043] By providing a plurality of such net claw portions 51 along the entire length of the fence furring strip 1, the net 3 can be fixed at the top and bottom of the fence 100.

[0044] In this embodiment, it has been explained that the net claw portion 51 is formed by shearing a portion of the vertical edges 20a, 20b through press processing and plastically deforming it, but the method of providing the net claw portion 51 is not limited to this, and it may also be formed from a material equivalent to the first furring strip 1a and the second furring strip 1b and attached to the vertical edges 20a, 20b by welding.

[0045] Next, a method for connecting the first furring strip 1a and the second furring strip 1b in the longitudinal direction of the fence furring strip 1 having the above-mentioned characteristics will be described.

[0046] 7(a) is a rear view seen from the inside in the width direction showing the preparation stage for connecting the fence furring strips 1, FIG. 7(b) is a Y1-Y1 cross-sectional view of FIG. 7(a), FIG. 8(a) is a rear view seen from the inside in the width direction showing the connecting claw portion 13 on the vertical side 20a side having been inserted into the second hole portion 41, FIG. 8(b) is a Y2-Y2 cross-sectional view of FIG. 8(a), FIG. 9(a) is a rear view seen from the inside in the width direction showing the connecting claw portion 13 on the horizontal side 10a side having been inserted into the first hole portion 31, FIG. 9(b) is a Y3-Y3 cross-sectional view of FIG. 9(a), FIG. 9(c) is a Z1-Z1 cross-sectional view of FIG. 9(a), FIG. 10(a) is a rear view seen from the inside in the width direction showing the completed connection of the fence furring strips 1, and FIG. 10(b) is a Z2-Z2 cross-sectional view of FIG. 10(a).

[0047] First, as shown in Figures 7(a) and (b), the first furring strip 1a is brought close so that the drawn portion 12 is positioned inside the rear end of the second furring strip 1b. At this time, either the first furring strip 1a or the second furring strip 1b is temporarily fixed to the already erected support 2 by a fastener or a claw portion (not shown). The temporarily fixed first furring strip 1a or the second furring strip 1b can move in the longitudinal direction, but there is no risk of it falling to the ground during the connecting work.

[0048] Next, as shown in Fig. 8(b), the connecting claw portion 13 provided on the vertical side 20a side is inserted into the second hole portion 41, and the inner surface of the vertical side 20b is brought into contact with the outer surface of the drawn portion 12. At this time, the connecting claw portion 13 on the horizontal side 10a side is located inside the inner surface of the horizontal side 10b of the second furring strip 1b.

[0049] 9(a) and 9(b), the connecting claw 13 provided on the horizontal side 10a is inserted into the first hole 31, and the inner surface of the horizontal side 10b is brought into contact with the outer surface of the tapered portion 12. As described above, the width dimension D of the second hole 41 is formed to be at least larger than the sum of the width dimension C of the connecting claw 13 and the height dimension E of the engagement portion 15. Therefore, even after the connecting claw 13 is inserted into the second hole 41, the first furring strip 1a and the second furring strip 1b can be brought relatively closer in the height direction.

[0050] Thereafter, as shown in FIG. 10(a), the first body edge 1a and the second body edge 1b are relatively moved in the longitudinal direction in a direction to reduce the area where the constriction portion 12 of the first body edge 1a and the rear end portion of the second body edge 1b overlap. At this time, as shown in FIG. 10(b), the rear end portion of the second body edge 1b is sandwiched in the gap between the engagement portion 15 and the constriction portion 12 of the first body edge 1a, and the connecting claw portion 13 engages with the first hole portion 31 and the second hole portion 41.

[0051] As described above, in the present embodiment, by restraining the first body edge 1a and the second body edge 1b by the two side edges of the horizontal sides 10a, 10b and the vertical sides 20a, 20b, rattling in both the width direction and the height direction can be prevented, and the fence body edge 1 can be firmly connected. Further, the fence body edge 1 according to the present invention can be connected without using parts such as a joint piece, bolts, and nuts that were required when connecting conventional body edges, and the connecting operation can also be performed without using tools. Therefore, the first body edge 1a and the second body edge 1b can be easily connected and can also be easily disassembled.

[0052] In this embodiment, the engaging portion 15 of the connecting claw portion 13 formed on the horizontal and vertical surfaces of the drawn portion 12 is formed so as to be substantially parallel to the horizontal or vertical surface and extend from the rising portion 14 toward the rear end of the first furring strip 1a. However, the shape of the engaging portion 15 of either the connecting claw portion 13 formed on the horizontal or vertical surface is not limited to the above, and the engaging portion 15 may be inclined with respect to the horizontal or vertical surface and the tip of the engaging portion 15 may be folded back toward the outside in the height direction or the outside in the width direction, as in the first modified example of the connecting claw portion 13 shown in FIG. 11(a). Also, as in the second modified example of the connecting claw portion 13 shown in FIG. 11(b), a part of the engaging portion 15 may be embossed to reduce the distance between the horizontal or vertical surface and the embossed portion of the engaging portion 15. In these modified examples of the connecting claw portion 13, it is preferable that the portion where the distance between the horizontal or vertical surface and the engaging portion 15 is the smallest is formed to be equal to or slightly smaller than the plate thickness t of the drawn portion 12. It is also preferable that the distance between the horizontal or vertical surface and the tip of the engaging portion 15 is formed to be greater than the plate thickness t of the drawn portion 12. In this way, by reducing the distance between the horizontal or vertical surface and the engaging portion 15, the side edge of the drawn portion 12 can be held more firmly, and the first furring strip 1a and the second furring strip 1b can be more firmly connected. In addition, by making the distance between the horizontal or vertical surface and the tip of the engaging portion 15 greater than the plate thickness t of the drawn portion 12, the connecting claw portion 13 can easily engage with the first hole portion 31 or the second hole portion 41. In this embodiment, if such a modification is applied to both the connecting claws 13 formed on the horizontal plane and the connecting claws 13 formed on the vertical plane, there is a risk that the force required to move the first furring strip 1a and the second furring strip 1b relatively in the longitudinal direction when connecting the first furring strip 1a and the second furring strip 1b may become excessive. Therefore, it is preferable to apply the first or second modification of the connecting claws 13 to only one of the connecting claws 13 formed on the horizontal plane or the vertical plane.

[0053] In this embodiment, the connecting claw portion 13 protrudes outward from the narrowed portion 12 of the first furring strip 1a, and the first hole portion 31 and the second hole portion 41 are formed at the rear end of the second furring strip 1b. However, the positions of the connecting claw portion 13, the first hole portion 31, and the second hole portion 41 are not limited to this, and the connecting claw portion 13 may be provided on the inner surface of the rear end of the second furring strip 1b and protrude inward, and the first hole portion 31 and the second hole portion 41 may be formed at the narrowed portion 12 of the first furring strip 1a. In addition, in the above, the engaging portion 15 extends from the rising portion 14 toward the rear end side, but the positional relationship between the rising portion 14 and the engaging portion 15 is not limited to this, and the rising portion 14 may be located at the rear end side of the connecting claw portion 13, and the engaging portion 15 may be formed to extend from the rising portion 14 toward the tip side. In this case, the first furring strip 1a and the second furring strip 1b are connected by moving them relatively in the longitudinal direction in a direction that increases the area where the drawn portion 12 and the rear end of the second furring strip 1b overlap. In addition, the above description has been given of the case where the connecting claw portion 13 is formed by shearing a part of the surface of the drawn portion 12 by press processing and plastically deforming it, but the connecting claw portion 13 may be attached to the drawn portion 12 by welding. In addition, the description has been given of the case where the tapered portion 11 is formed so as to be inclined with respect to the horizontal sides 10a, 10b and the vertical sides 20a, 20b, and is connected to the drawn portion 12, but the tapered portion 11 may be formed in a stepped shape that is perpendicular to the horizontal sides 10a, 10b and the vertical sides 20a, 20b. In addition, although the side length A of the horizontal sides 10a, 10b and the side length B of the vertical sides 20a, 20b are the same in the above description, side length A and side length B may be different lengths. It is clear from the claims that such modified or improved embodiments are also included within the technical scope of the present invention. [Explanation of symbols]
