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. In addition, if the total length of one furring strip is shorter than the installation length of the fence, the fence is constructed by connecting multiple furring strips in the longitudinal direction.

[0003] As shown in Figure 12, 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 is 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.

[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 drawing 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 direction and orientation of the arrows shown in Fig. 2. In this specification, the height direction, width direction, and inside and outside of the fence furring strip are defined as the direction and orientation of the arrows shown in Fig. 2. In this specification, the front view and plan view of the fence furring strip are defined as views seen from the direction 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 11, 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 will be described in a state where it is attached to the lower 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 inside 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 inside 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 furring strip 1a and the second furring strip 1b are connected, the outer surface of the drawn portion 12 abuts against the inner surface of the rear end of the second furring strip 1b. When the first furring strip 1a and the second furring strip 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 imaginary plane F and the vertical side 20a and the vertical side 20b are located in the same imaginary plane G, the straightness of the fence furring strip 1 after connection can be maintained and the aesthetic appearance is not impaired. Therefore, it is preferable that the outer surface of the drawn portion 12 is formed so that it is recessed inward by the plate thickness t from the outer surfaces of the horizontal side 10a and the vertical side 20a.

[0031] As shown in FIG. 5(a), a plurality of through holes 13 are formed in the vertical surface of the narrowed portion 12 at intervals in the longitudinal direction.

[0032] As shown in Fig. 5(a), the through hole 13 is formed as a long hole in which two semicircles are connected by a rectangle extending in the longitudinal direction with a side length (hereinafter referred to as the width of the through hole 13) equal to the diameter of the circle. The through hole 13 is a through hole that engages with a connecting claw portion 21 described later, and is formed at a position corresponding to the connecting claw portion 21 when the first furring strip 1a and the second furring strip 1b are connected. In this specification, the longitudinal size of the through hole 13 is defined as dimension C1, and the width of the through hole 13 is defined as dimension D1.

[0033] As shown in Figs. 5(a) and 5(b), a plurality of connecting claws 21 that engage with the through holes 13 are formed at intervals in the longitudinal direction at the rear end of the second furring strip 1b.

[0034] 5(b), the connecting claw portion 21 has a rising portion 22 that protrudes inward in the width direction from the inner surface of the vertical side 20b, and an engaging portion 23 that is approximately parallel to the vertical side 20b and extends from the rising portion 22 toward the tip side of the second furring strip 1b. The connecting claw portion 21 is formed by shearing a part of the vertical side 20b by, for example, press working, and plastically deforming it.

[0035] The rising portion 22 is formed so that the distance between the inner surface of the vertical side 20b and the surface of the engagement portion 23 facing outward in the width direction is at least the plate thickness t and is a distance necessary to sandwich the side edge of the tapered portion 12. As shown in Fig. 5(b), the rising portion 22 may be formed so as to be inclined with respect to the vertical side 20b, or may be formed so as to be perpendicular to the vertical side 20b. In this specification, the distance between the inner surface of the vertical side 20b and the surface of the engagement portion 23 facing outward in the width direction is defined as dimension S1.

[0036] The engaging portion 23, together with the inner surface of the vertical edge 20b, holds the side of the tapered portion 12 when the first furring strip 1a and the second furring strip 1b are connected. The engaging portion 23 is formed so that the tip is semicircular in the front view shown in Fig. 5(a). In this specification, the longitudinal size from the tip of the engaging portion 23 to the rising portion 22 is defined as dimension C2, as shown in Fig. 5(b).

[0037] The longitudinal dimension C2 of the engaging portion 23 is set to a length sufficient to prevent the engaging portion 23, which holds the side edge of the narrowed portion 12, from coming off due to vibration or the like when the first furring strip 1a and the second furring strip 1b are connected and used as the furring strip of the fence 100. In addition, the longitudinal dimension C2 of the engaging portion 23 is set to be smaller than the longitudinal dimension C1 of the through hole 13.

[0038] In the front view shown in Fig. 5(a), the rising portion 22 and the engaging portion 23 are formed so that the width gradually narrows from the connection portion of the rising portion 22 with the vertical side 20b to the tip of the engaging portion 23. In this specification, in the front view shown in Fig. 5(a), the size in the height direction of the connection portion of the rising portion 22 with the vertical side 20b (hereinafter referred to as the width of the rising portion 22) is dimension D2, and the size in the height direction on the tip side of the engaging portion 23 (hereinafter referred to as the width of the engaging portion 23) is dimension D3.

[0039] The width dimension D2 of the rising portion 22 is set to a size that maintains sufficient strength when the first furring strip 1a and the second furring strip 1b are connected, and is set to be equal to or slightly larger than the width dimension D1 of the through hole 13. Moreover, the width dimension D3 of the engagement portion 23 is set to be smaller than the width dimension D1 of the through hole 13 so that it can pass through the through hole 13.

[0040] In this embodiment, the connecting claw 21 is formed by shearing a part of the vertical side 20b by press processing and plastically deforming it, but the method of providing the connecting claw 21 is not limited to this, and the connecting claw 21 may be formed from the same material as the first furring strip 1a and the second furring strip 1b and attached to the vertical side 20b by welding. Also, the shape of the rising portion 22 and the engaging portion 23 is formed so as to gradually narrow from the width dimension D2 of the rising portion 22 to the width dimension D3 of the engaging portion 23 in the front view, but the shape of the rising portion 22 and the engaging portion 23 is not limited to this, and may be a constant dimension smaller than the width dimension D1 of the through hole 13.

[0041] Next, the shape of the fence furring strip 1 other than the connecting portions in this embodiment will be described.

[0042] 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.

[0043] As shown in the cross-sectional view of FIG. 6, the net claw portion 51 has a rising portion 52 that protrudes inward in the width direction from the inner surfaces of the vertical sides 20a and 20b, and an engaging portion 53 that extends from the rising portion 52 toward the horizontal sides 10a and 10b. The net claw portion 51 is formed, for example, by shearing a part of the vertical sides 20a and 20b by press working and plastically deforming them.

[0044] The rising portion 52 is formed so as to separate from the inner surfaces of the vertical sides 20a and 20b by a distance necessary to bridge the wire 54 for attaching the net 3 by the distance necessary to bridge the wire 54 for attaching the net 3 from the surfaces facing the outside in the width direction of the engaging portion 53. In this specification, the distance between the surface facing the outside in the width direction of the engaging portion 53 and the inner surfaces of the vertical sides 20a and 20b is defined as dimension S2. The dimension S2 is formed to be larger than the wire diameter of the wire 54. Further, as shown in FIG. 6, the rising portion 52 may be formed to be inclined with respect to the vertical sides 20a and 20b, or may be formed to be perpendicular to the vertical sides 20a and 20b.

[0045] When attaching the net 3, the wire 54 passes between the engaging portion 53 and the inner surfaces of the horizontal sides 10a and 10b. Therefore, for the purpose of preventing damage to the wire 54, as shown in FIG. 5(a), it is preferable that the engaging portion 53 is formed such that the shape of the tip portion is a semi-circle. In this specification, as shown in FIG. 6, the distance from the tip portion of the engaging portion 53 to the inner surfaces of the horizontal sides 10a and 10b is defined as dimension S3. The dimension S3 is formed to be larger than the wire diameter of the wire 54 for attaching the net 3 and to be separated by a distance sufficient to allow the wire 54 to pass through.

[0046] By providing a plurality of such net claw portions 51 over the entire length of the fence body edge 1, the net 3 can be fixed at the upper and lower portions of the fence 100.

[0047] In this embodiment, the net claws 51 are formed by shearing a part of the vertical sides 20a, 20b by press processing and plastically deforming them, but the method of providing the net claws 51 is not limited to this, and they may be formed from the same material as the first furring strip 1a and the second furring strip 1b and attached to the vertical sides 20a, 20b by welding. In addition, it is preferable to form the connecting claws 21 and the net claws 51 in the same shape, as this reduces manufacturing costs.

[0048] 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.

[0049] Figure 7 is a plan view seen from the inside in the height direction, showing the state of the fence furring strips 1 in the preparation stage for connection; Figure 8 is a plan view seen from the inside in the height direction, showing the process of connecting the fence furring strips 1, with the connecting claw portion 21 inserted into the through hole 13; Figure 9 shows the state when the connection of the fence furring strips 1 has been completed, with Figure 9(a) being a front view seen from the inside in the width direction, and Figure 9(b) being a plan view seen from the inside in the height direction.

[0050] First, as shown in Fig. 7, 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.

[0051] Next, as shown in Fig. 8, the connecting claw portion 21 of the second furring strip 1b is inserted into the through hole 13 of the first furring strip 1a. At this time, it is preferable that the position of the tapered portion 11 and the longitudinal position of the connecting claw portion 21 are set so that the tapered portion 11 of the first furring strip 1a and the rear end portion of the second furring strip 1b do not interfere with each other.

[0052] Subsequently, as shown in FIGS. 9(a) and 9(b), the first body edge 1a and the second body edge 1b are relatively moved longitudinally 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, the rising portion 22 formed to be inclined with respect to the vertical side 20b of the second body edge 1b guides the edge of the through hole 13 of the first body edge 1a, and the outer surface of the constriction portion 12 of the first body edge 1a approaches so as to engage with the inner surface of the vertical side 20b of the second body edge 1b. In this way, as shown in FIG. 9(b), the vertical surface of the constriction portion 12 of the first body edge 1a is sandwiched between the inner surface of the vertical side 20b of the second body edge 1b and the surface facing the outer side in the width direction of the engaging portion 23, and the connecting claw portion 21 engages with the through hole 13. Further, as shown in FIG. 9(a), since the dimension D2 of the width of the rising portion 22 is set to be equal to or slightly larger than the dimension D1 of the width of the through hole 13, the rising portion 22 is fixed so as to bite into the through hole 13.

[0053] As described above, the first body edge 1a and the second body edge 1b according to the present embodiment can be easily connected only by the engagement of the plurality of connecting claw portions 21 and the plurality of through holes 13. Further, since the plurality of connecting claw portions 21 and the plurality of through holes 13 are formed side by side in a row along the longitudinal direction, relative swaying of the first body edge 1a and the second body edge 1b after connection can be prevented, and a fence body edge 1 with high straightness can be constructed. Further, since the through hole 13 is provided in the vertical surface of the constriction portion 12 and the connecting claw portion 21 is provided in the vertical side 20b, a structure in which rainwater hardly accumulates at the connection portion can be achieved as compared with the case where it is provided in the horizontal surface of the constriction portion 12 or the horizontal side 10b. Further, since the rising portion 22 is fixed so as to bite into the through hole 13, rattling between the first body edge 1a and the second body edge 1b after connection can be prevented. Further, by making the connecting claw portion 21 and the net claw portion 51 have the same shape, the manufacturing cost of the first body edge 1a and the second body edge 1b can be reduced. Further, the fence body edge 1 according to the present invention can be connected without using parts such as joint pieces and bolt nuts that are 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.

[0054] In the present embodiment, the engaging portion 23 of the connecting claw portion 21 has been described in the case where it is substantially parallel to the vertical side 20b and is formed so as to extend from the rising portion 22 toward the tip side of the second body edge 1b. However, the shape of the engaging portion 23 is not limited to this. As in the first modification example of the connecting claw portion 21 shown in Fig. 10(a), the engaging portion 23 may be inclined with respect to the vertical side 20b to reduce the dimension S1, and the tip portion of the engaging portion 23 may be formed so as to be folded back toward the inner side in the width direction. Also, as in the second modification example of the connecting claw portion 21 shown in Fig. 10(b), embossing may be performed on a part of the engaging portion 23 so that the dimension S1 is partially reduced. In these first and second modification examples of the connecting claw portion 21, it is preferable that the dimension S1 is formed to be equal to or slightly smaller than the plate thickness t of the constriction portion 12. Also, it is preferable that the distance between the inner surface of the vertical side 20b and the tip portion of the engaging portion 23 is formed to be larger than the plate thickness t of the constriction portion 12. Thus, by reducing the dimension S1, which is the distance between the inner surface of the vertical side 20b and the engaging portion 23, the side edges of the constriction portion 12 can be held more firmly, and the first body edge 1a and the second body edge 1b can be connected more firmly. Also, by making the distance between the inner surface of the vertical side 20b and the tip portion of the engaging portion 23 larger than the plate thickness t of the constriction portion 12, the connecting claw portion 21 can easily engage with the through hole 13.

[0055] In this embodiment, the through hole 13 is formed in the narrowed portion 12 of the first furring strip 1a, and the connecting claw portion 21 protrudes from the rear end of the second furring strip 1b toward the inside in the width direction, but the positions of the through hole 13 and the connecting claw portion 21 are not limited to this, and the through hole 13 may be provided at the rear end of the second furring strip 1b, and the connecting claw portion 21 may be formed from the vertical surface of the narrowed portion 12 of the first furring strip 1a toward the outside in the width direction. In addition, in the above, the engaging portion 23 extends from the rising portion 22 toward the tip side of the second furring strip 1b, but the positional relationship between the rising portion 22 and the engaging portion 23 is not limited to this, and the rising portion 22 may be located at the tip side of the connecting claw portion 21, and the engaging portion 23 may extend from the rising portion 22 toward the rear end side. In this case, the first furring strip 1a and the second furring strip 1b are connected by moving relatively in the longitudinal direction in a direction to increase the overlapping area of ​​the drawn portion 12 and the rear end of the second furring strip 1b. In addition, the tapered portion 11 is formed 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. However, 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.
