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 hanging multiple furring strips made of angle bars or similar between posts erected at intervals in the ground, and then stretching a net over the furring strips. Also, if the total length of a single 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 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 with a side that is shorter than the side of the furring strip.

[0004] Furthermore, Patent Document 1 describes a connection structure for angle bars for fence furring strips, etc., which simplifies the work of aligning the bolt holes of two adjacent furring strips when connecting the furring strips, and ensures the linearity of the furring strips after connection and a secure fastening mechanism without any rattle.

[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 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 save on 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 saves on 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 temporary fences that are temporarily installed and are scheduled 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 matters, and its object is to provide a furring strip for a fence that can be connected using only the furring strip, without using fastening parts such as joint pieces or bolts and nuts, and that allows the fence to be easily assembled and disassembled. [Means for solving the problem]

[Figure 12] A reference perspective view showing a conventional method for connecting furring strips for fences DETAILED DESCRIPTION OF THE INVENTION

[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 not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0022] Fig. 1 is a reference diagram showing one form of 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 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 erected at intervals on the ground at the height that forms the upper and lower edges of the fence 100, and fixes the net 3.

[0024] As shown in Figure 1, for example, the posts 2 include main posts 2a with netting 3 on both sides and a generally V-shaped cross section, and end posts 2b with netting 3 on one side and a generally L-shaped cross section. Both the main posts 2a and end posts 2b are formed, for example, from general structural rolled steel. Furthermore, the main posts 2a and end posts 2b are provided with through-holes for passing bolts at the heights that correspond to the upper and lower edges of the fence 100, and the fence furring strips 1 are attached to the posts 2 using bolts that pass through the through-holes and fasteners (not shown).

[0025] As an example, the net 3 is a wire mesh made from iron wires that have been processed into a series of mountains and woven together to form a diamond-shaped mesh. The mesh joints are not fixed by welding or other means, so they have shock absorption properties. As shown in Figure 11, the net 3 has iron wires 54 threaded through the upper and lower edges, and is attached by hooking the iron wires 54 onto the net claws 51 of the fence furring strips 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 a first furring strip 1a and the rear end (the other end in the claims) of a second furring strip 1b, which are adjacent fence furring strips. FIG. 4 is a perspective view showing the first furring strip 1a and the second furring strip 1b before they 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, by continuously connecting the first furring strip 1a and the second furring strip 1b in the longitudinal direction, a continuous furring strip of the required length can be formed.

[0027] As shown in FIG. 4, the first furring strip 1a and the second furring strip 1b are elongated components with a generally L-shaped cross section, with side lengths A and B and a thickness t, and lengths L1 and L2, respectively. The first furring strip 1a and the second furring strip 1b are formed, for example, from general structural rolled steel. To prevent corrosion, they are preferably galvanized or electrostatically powder coated with a polyester resin base. In this specification, the horizontally positioned sides of the first furring strip 1a and the second furring strip 1b are referred to as horizontal sides 10a and 10b, and the vertically positioned sides are referred to as vertical sides 20a and 20b, depending on the mounting orientation of the fencing 100. In this embodiment, the side length A of the horizontal sides 10a and 10b and the side length B of the vertical sides 20a and 20b are preferably the same length. In the following description, the first furring strip 1a and the second furring strip 1b are attached to the lower edge of the 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, showing the state before adjacent furring strips are connected, and Figure 5(b) is a plan view 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 consists 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 and the outer surfaces of the horizontal side 10a and the vertical side 20a, which are not recessed inward, are smoothly connected by a tapered portion 11.

[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 Figures 5(a) and 5(b), if the horizontal edges 10a and 10b are located within the same imaginary plane F and the vertical edges 20a and 20b are located within the same imaginary plane G, the straightness of the fence furring strip 1 after connection can be maintained without compromising the aesthetic appearance. Therefore, it is preferable that the outer surface of the drawn portion 12 be recessed inward by the plate thickness t from the outer surfaces of the horizontal edges 10a and the vertical edges 20a.

[0031] As shown in FIG. 5(b), a plurality of substantially T-shaped through holes 13 are formed in the horizontal surface of the narrowed portion 12 along the longitudinal direction.

[0032] As shown in Figure 5(b), the through hole 13 has a rectangular introduction groove 14 extending in the longitudinal direction, and an engagement groove 15 extending from approximately the center of the introduction groove 14 in the longitudinal direction toward the inside in the width direction in a direction intersecting the longitudinal direction.

[0033] As shown in Figure 5(b), the introduction groove 14 is formed into a rectangle whose widthwise size of the first furring strip 1a (hereinafter referred to as the width of the introduction groove 14) is a constant dimension D1 and whose longitudinal size (hereinafter referred to as the length of the introduction groove 14) is a dimension C1.

[0034] As shown in FIG. 5(b), the engagement groove 15 is connected to the approximate center of the introduction groove 14 in the longitudinal direction and extends inward in the width direction in a direction intersecting the longitudinal direction. The engagement groove 15 is formed to have a generally trapezoidal shape, with the connecting portion with the introduction groove 14 as the short side and the side away from the introduction groove 14 as the long side. The corners of the connecting portion between the introduction groove 14 and the engagement groove 15 are chamfered or curved. Therefore, the engagement groove 15 has a narrower gap in part, forming a constricted portion 16. In this specification, the gap between the constricted portions 16 is defined as dimension E1. The length of the side of the engagement groove 15 that is located away from the introduction groove 14 and corresponds to the long side of the generally trapezoidal shape is defined as dimension E2.

[0035] As shown in FIGS. 5(a) and 5(b), a plurality of connecting claws 21 are formed at intervals in the longitudinal direction on the horizontal side 10b at the rear end of the second furring strip 1b.

[0036] As shown in FIG. 5(a), the connecting claw 21 includes a first rising portion 22a and a second rising portion 22b that protrude inward in the height direction from the inner surface of the horizontal side 10b, a first engaging portion 23a that extends from the first rising portion 22a toward the front end, and a second engaging portion 23b that extends from the second rising portion 22b toward the rear end. The substantially L-shaped claw portion formed by the first rising portion 22a and the first engaging portion 23a and the substantially L-shaped claw portion formed by the second rising portion 22b and the second engaging portion 23b are arranged in a row along the longitudinal direction. The connecting claw 21 is formed by shearing a portion of the horizontal side 10b using, for example, press working, and plastically deforming it.

[0037] The first rising portion 22a and the second rising portion 22b are formed so that the distance between the inner surface of the horizontal side 10b and the surfaces of the first engagement portion 23a and the second engagement portion 23b facing outward in the height direction is at least equal to the plate thickness t and is a distance necessary to sandwich the side edges of the drawn portion 12. As shown in FIG. 5(a), the first rising portion 22a and the second rising portion 22b may be formed so as to be inclined with respect to the horizontal side 10b, or may be formed so as to be perpendicular to the horizontal side 10b. In this specification, the distance between the inner surface of the horizontal side 10b and the surfaces of the first engagement portion 23a and the second engagement portion 23b facing outward in the height direction is defined as dimension S1.

[0038] 5(a), the distance between the surface of the first rising portion 22a facing the leading edge and the surface of the second rising portion 22b facing the rear edge is defined as dimension E3. The surface of the first rising portion 22a facing the leading edge and the surface of the second rising portion 22b facing the rear edge are formed so as to abut against the constricted portion 16 and slightly expand the constricted portion 16 when the first furring strip 1a and the second furring strip 1b are connected. In other words, dimension E3, which is the distance between the first rising portion 22a and the second rising portion 22b, is formed so as to be slightly larger than dimension E1, the spacing between the constricted portions 16, and smaller than dimension E2, the length of the sides of the engagement groove 15.

[0039] 5(b), the first rising portion 22a, the second rising portion 22b, and the first engaging portion 23a, the second engaging portion 23b are formed so that their widthwise size is a constant dimension D2. Note that dimension D2 is set to a size that allows the first rising portion 22a and the second rising portion 22b to maintain sufficient strength when the first furring strip 1a and the second furring strip 1b are connected, and is formed so that it is smaller than the width dimension D1 of the guide groove 14.

[0040] The first engaging portion 23a and the second engaging portion 23b, together with the inner surface of the second furring strip 1b, hold the side edges of the tapered portion 12 when the first furring strip 1a and the second furring strip 1b are connected. The first engaging portion 23a and the second engaging portion 23b are formed to be approximately rectangular in the plan view shown in FIG. 5(b). In this specification, the distance between the leading end face of the first engaging portion 23a and the trailing end face of the second engaging portion 23b is defined as dimension C2. The first engaging portion 23a and the second engaging portion 23b are formed to pass through the guide groove 14 and engage with the engagement groove 15 when the first furring strip 1a and the second furring strip 1b are connected. Therefore, dimension C2 is formed to be smaller than dimension C1, which is the length of the guide groove 14, and larger than dimension E2, which is the length of the side of the engagement groove 15.

[0041] In this embodiment, the connecting claws 21 are formed by shearing a portion of the horizontal edge 10b by press working and plastically deforming it, but the method of providing the connecting claws 21 is not limited to this, and the connecting claws 21 may be formed from the same material as the first furring strip 1a and the second furring strip 1b and attached to the horizontal edge 10b by welding. Also, the first engaging portion 23a and the second engaging portion 23b are described as being substantially rectangular in the plan view shown in Figure 5(b), but the shapes of the first engaging portion 23a and the second engaging portion 23b are not limited to this, and the tips may be semicircular.

[0042] Next, the shape of the fence furring strip 1 other than the connecting portions in this embodiment will be described.

[0043] As shown in Figure 2, multiple 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.

[0044] 6, the net claw portions 51 have rising portions 52 that protrude inward in the width direction from the inner surfaces of the vertical sides 20a, 20b, and engaging portions 53 that extend from the rising portions 52 toward the horizontal sides 10a, 10b. The net claw portions 51 are formed by shearing and plastically deforming parts of the vertical sides 20a, 20b, for example, by press working.

[0045] The rising portions 52 are formed so that the surfaces of the engaging portions 53 facing outward in the width direction are spaced from the inner surfaces of the vertical sides 20a, 20b by a distance necessary for suspending the iron wires 54 for attaching the net 3. In this specification, the distance between the surfaces of the engaging portions 53 facing outward in the width direction and the inner surfaces of the vertical sides 20a, 20b is defined as dimension S2. Therefore, dimension S2 is formed to be larger than the wire diameter of the iron wires 54. Furthermore, the rising portions 52 may be formed so as to be inclined with respect to the vertical sides 20a, 20b, as shown in FIG. 6, or so as to be perpendicular to the vertical sides 20a, 20b.

[0046] When attaching the net 3, iron wires 54 pass between the engaging portions 53 and the inner surfaces of the horizontal sides 10a and 10b. Therefore, in order to prevent damage to the iron wires 54, it is preferable that the engaging portions 53 are formed so that their tips are semicircular, as shown in FIG. 5(a). In this specification, the distance from the tips of the engaging portions 53 to the inner surfaces of the horizontal sides 10a and 10b is defined as dimension S3, as shown in FIG. 6. Dimension S3 is larger than the wire diameter of the iron wires 54 used to attach the net 3, and is formed to be a distance sufficient to allow the iron wires 54 to pass through.

[0047] 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.

[0048] 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 by 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 that of the first furring strip 1a and the second furring strip 1b and attached to the vertical edges 20a, 20b by welding.

[0049] 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.

[0050] Figure 7 shows the state of the fence furring strips 1 in the preparation stage for connection, with Figure 7(a) being a front view seen from the inside in the width direction, and Figure 7(b) being a plan view seen from the inside in the height direction. Figure 8 shows the state where the connecting claw portion 21 has been inserted into the through hole 13, with Figure 8(a) being a front view seen from the inside in the width direction, and Figure 8(b) being a plan view seen from the inside in the height direction. Figure 9 shows the state where 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.

[0051] 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 with fasteners or claws (not shown). The temporarily fixed first furring strip 1a or 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.

[0052] Next, as shown in Figures 8(a) and 8(b), the connecting claws 21 of the second furring strip 1b are inserted into the guide grooves 14 of the first furring strip 1a. At this time, it is preferable to set the position of the tapered portion 11 and the longitudinal position of the connecting claws 21 so that the tapered portion 11 of the first furring strip 1a and the rear end of the second furring strip 1b do not interfere with each other.

[0053] Next, as shown in Figures 9(a) and 9(b), the first furring strip 1a and the second furring strip 1b are moved relatively in the width direction (in the direction of the arrow in Figure 9) so as to increase the overlap area between the drawn portion 12 of the first furring strip 1a and the rear end of the second furring strip 1b. If necessary, a rubber hammer or similar tool may be used to strike the vertical edge 20b of the second furring strip 1b from the outside in the width direction to apply force and move the first furring strip 1a and the second furring strip 1b relatively in the width direction. As a result, as shown in Figure 9(b), the first raised portion 22a and the second raised portion 22b are guided into the engagement groove 15, and the side edges of the drawn portion 12 are sandwiched between the inner surface of the horizontal edge 10b of the second furring strip 1b and the surfaces facing outward in the height direction of the first engagement portion 23a and the second engagement portion 23b, and the connecting claws 21 engage with the engagement groove 15. Furthermore, the dimension E3 of the distance between the first rising portion 22a and the second rising portion 22b is set to be slightly larger than the dimension E1 of the spacing between the constricted portions 16, so that the first rising portion 22a and the second rising portion 22b are fixed so as to be bitten into the constricted portions 16.

[0054] In this way, the first furring strip 1a and the second furring strip 1b can be connected by moving them relatively in the width direction, so even if the fence furring strip 1 that forms the lower edge of the fence 100 is located close to the ground, the connecting work using a rubber hammer or the like can be easily carried out compared to connecting them by moving them relatively in the height direction. Also, connecting can be done with less effort compared to connecting long members by moving them longitudinally.

[0055] As described above, the first furring strip 1a and the second furring strip 1b according to this embodiment can be easily connected using the multiple connecting claws 21 and the multiple through-holes 13. Furthermore, because the multiple connecting claws 21 and the multiple through-holes 13 are aligned longitudinally, relative wobble between the first furring strip 1a and the second furring strip 1b is prevented after connection, resulting in a fence furring strip 1 with high straightness. Furthermore, because the first rising portion 22a and the second rising portion 22b are fixed by engaging with the constricted portion 16, rattle between the first furring strip 1a and the second furring strip 1b after connection is prevented. Furthermore, the fence furring strip 1 according to this invention can be connected using only the furring strips without using fastening parts such as joint pieces and bolts and nuts that are required when connecting conventional furring strips. This allows for easy assembly and disassembly of the fence 100.

[0056] Furthermore, in the above, we have described an embodiment in which the first furring strip 1a and the second furring strip 1b are connected only by the engagement of the connecting claw portion 21 and the through hole 13, without using bolts and nuts. However, if it is difficult to form a shape in which the spacing is narrow in some areas, such as the constricted portion 16, or if the dimension E1 of the spacing of the constricted portion 16 becomes wider as a result of repeated assembly and disassembly, or if the dimension E3 of the distance between the first rising portion 22a and the second rising portion 22b becomes narrow, it is also possible to form holes in the vertical edges 20a and 20b to pass bolts through, and fix the first furring strip 1a and the second furring strip 1b with bolts and nuts, as shown in Figure 10.

[0057] In the above, the through-hole 13 is formed in the horizontal plane of the drawn portion 12 of the first furring strip 1a, and the connecting claw 21 protrudes inward in the height direction from the rear end of the second furring strip 1b. However, the positions of the through-hole 13 and the connecting claw 21 are not limited to this, and the through-hole 13 may be provided in the rear end of the second furring strip 1b, and the connecting claw 21 may be formed outward in the height direction from the horizontal plane of the drawn portion 12 of the first furring strip 1a. In this case, it is preferable that the shape of the through-hole 13 is approximately T-shaped, with the engagement groove 15 extending from approximately the center of the guide groove 14 outward in the width direction. In addition, although the tapered portion 11 has been described as being formed so as to be inclined with respect to the horizontal sides 10a, 10b and the vertical sides 20a, 20b and connected to the narrowed portion 12, 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. Furthermore, although the side length A of the horizontal sides 10a, 10b and the side length B of the vertical sides 20a, 20b have been described as being the same length, the side lengths A and B may be different lengths.
