Description

Technical Field

[0001] The present invention relates to a fence in which a plurality of strip-shaped bodies (hereinafter referred to as "blades" in the present application) are installed in parallel within a rectangular frame body, and blade locking members that lock each of the plurality of blades and are fixedly installed on the frame body of the fence.

Background Art

[0002] In recent years, as enclosures for structures and sites, a lattice fence (see Patent Document 1) in which rod-shaped bodies are installed diagonally in a lattice pattern within a rectangular frame, a border fence (see Patent Document 2) in which blades are installed in parallel within a rectangular frame, and a louver fence (see Patent Document 3) in which the blades are inclined to achieve both ventilation and screening functions are known. Although their components can be factory-produced, the work of assembling the rectangular frame and the work of attaching the rod-shaped bodies or strip-shaped bodies have to be done by hand. In particular, for a louver fence, since a large number of blades are inclined back and forth and attached to the frame body, it is an issue how to quickly and easily perform the connection between the rod-shaped bodies forming the frame and the connection between the rod-shaped bodies and the blades produced in the factory and how to produce them efficiently.

[0003] Therefore, a screening louver for outdoor installation in which fitting ridges arranged at both ends of a synthetic resin blade are slidably fitted into fitting grooves arranged on an aluminum anti-bending bar, and the anti-bending bar is fixed to the opposing frame and the fitting ridges are rotationally moved within the fitting grooves to tightly fit the fitting ridges into the fitting grooves, and a fence in which a large number of blades are arranged between left and right opposing frames, and thin-necked portions are arranged at both ends of the blade, and the fitting ridges at both ends are arranged via the necked portions has been proposed (see Patent Document 4). This enables the rotation of the fitting ridges to be facilitated, the bending of the blade to be facilitated by the arrangement of the necked portions, and the workability of fixing the anti-bending bar to the opposing frame to be improved, thereby achieving an improvement in the efficiency of the assembly work. Furthermore, a fence mounting structure has been proposed in which a horizontal blade is supported by a vertical support post, and the support post has a groove that extends vertically, and when the mounting device, which has a main body that is inserted into the groove and an opening in the main body into which the end of the blade can be inserted, is positioned between the end of the blade and the side surface of the groove, the end of the blade is positioned in the width direction of the groove (see Patent Document 5). This allows for the attachment of blades to the support column in a positioned manner, not only with a thickness that matches the opening width of the groove in the support column, but also with a thickness smaller than the opening width of the groove in the support column. Furthermore, the applicant has proposed a connector for joining the four corners of a frame, which includes openings at both ends of the rod-shaped members constituting the frame, an L-shaped section where two planar sections intersect perpendicularly, a first extension extending from the first planar section of the L-shaped section in the opposite direction to the second planar section, and a second extension extending from the second planar section in the same direction as the first planar section (see Patent Document 6). This allows the frame to be assembled efficiently and easily. [Prior art documents] [Patent Documents]

[0005] However, the louvers described in Patent Document 4 require fitting protrusions to be provided at the upper and lower ends of the synthetic resin blades, fixing aluminum deflection prevention bars to the opposing frames, and fitting the fitting protrusions to the deflection prevention bars to install the blades on the opposing frames. Therefore, processing of the blades and deflection prevention bars is required, and the installation of the deflection prevention bars is troublesome. Furthermore, the fence mounting structure described in Patent Document 5 requires that the support posts and blades be made of metal materials such as aluminum or stainless steel. Furthermore, while the connector described in Patent Document 6 is effective for fixing the four corners of the frame, it cannot be used to connect the vertical members installed inside the left and right members of the frame with the horizontal members installed above and below the frame. In view of the above circumstances, the objective is to provide a fence that allows for the easy and quick joining of factory-produced synthetic resin frame members to assemble a frame, and to allow for the easy and reliable attachment of blades to that frame, as well as a blade locking member that allows for the easy and convenient locking of blades and their secure attachment to the frame. [Means for solving the problem]

[0006] The present invention provides a fence comprising a rectangular frame formed by joining the upper and lower ends of rod-shaped bodies arranged parallel to each other in the vertical direction, with grooves having a predetermined width and depth along the entire length of the opposing surfaces of the rod-shaped bodies arranged parallel to each other in the vertical direction, and a blade of a predetermined length fixed horizontally between the grooves in the vertical direction, wherein the fence comprises a plurality of blade locking members having a width and height that fits into the grooves, and having a plurality of rectangular holes formed at equal intervals on the top surface for fitting the end faces of the blades, the blades being horizontally fitted and locked into the opposing holes of a pair of blade locking members with their top surfaces facing each other, and the blade locking members being fitted and fixed into the grooves provided on the opposing surfaces of the rod-shaped bodies. If the vertical rod-shaped members constituting the frame are provided with grooves of a predetermined width and depth, and a blade locking member having a width and height that fits into the groove and numerous rectangular holes in the longitudinal direction is provided, then by horizontally locking the blades into the opposing holes of a pair of blade locking members and fitting them into the groove, the blades can be easily and quickly attached to the frame, allowing for efficient assembly of the fence using factory-produced parts. In that case, it is preferable that the groove has a concave cross-section, with recesses formed in the longitudinal direction of each of the inner surfaces on both sides, and that the blade locking member has protrusions formed in the longitudinal direction of both sides that fit into the recesses, and that the orientation of the long side of the hole intersects with the protrusions, and that the blade has notches formed on both sides near the end, and that the blade locking member has projections formed on each of the short sides of the hole that engage with the notches. By configuring the groove shape of the frame and the blade locking member in this way, the blade, which is tilted forward or backward, can be easily and horizontally locked to the blade locking member, and the blade locking member can be securely fixed to the groove, thus allowing the blade to be installed on the frame efficiently. Furthermore, the frame is provided with an intermediate rod-shaped body having grooves formed on both sides, positioned vertically inward from the vertical left and right rod-shaped bodies forming the frame, and a first engaging member having a protruding member of the same width as the grooves, perpendicular to one of the L-shaped members formed by orthogonal plane members of the same size as the end faces of the rod-shaped bodies, and a protruding member perpendicular to the other plane member, perpendicular to the other plane member, and a protruding member perpendicular to the other plane member, opposite to the first plane member, and a second engaging member having a pair of L-shaped members formed by orthogonal plane members of flat plate members narrower than the grooves, with one flat plate member of each pair arranged in series and the other flat plate members arranged in parallel, and the distance between the parallel flat plate members being the same as the distance between the grooves formed on both sides of the intermediate rod-shaped body, and the four corners of the frame can be engaged using the first engaging member, and the intermediate rod-shaped body and the horizontal rod-shaped body can be engaged using the second engaging member. Then, the end faces of the blades can be fitted into the opposing holes of the pair of blade locking members and locked in place, and each of the blade locking members to which the blades are horizontally locked can be fitted into the grooves of the vertical rod-shaped body or the grooves of the intermediate rod-shaped body and screwed in place, and the protruding members of the first locking member can be inserted into the vertical and horizontal end faces of the rod-shaped body of the frame and screwed in place, and the other flat plate member of the second locking member can be inserted into the grooves on both sides of the intermediate rod-shaped body and screwed in place, and each of the flat plate members can be pressed against the grooves of the horizontal rod-shaped body and screwed in place. Using the first and second engaging members configured in this way, the fence frame can be assembled easily and efficiently.

[0007] The blade locking member of the present invention is a blade locking member of a predetermined length that locks multiple blades by fitting into a groove with a concave cross-section, which has recesses formed on both sides of its inner surface, and which is formed along the entire length of the opposing surfaces of a vertical rod-shaped body forming a rectangular frame, wherein the top surface has multiple rectangular holes formed at equal intervals for fitting and locking the end faces of the blades, and the outer surface has protrusions formed on both sides that fit into the recesses. In that case, it is preferable that the blade has notches formed on both sides near the end, and that the hole is formed such that the longer side forms a predetermined angle with the projection, and the shorter side has a projection that engages with the notch. Using such a blade locking member, the blade can be easily and efficiently attached to the fence frame horizontally by tilting it back and forth. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] An embodiment of the fence according to the present invention will be described below with reference to the figures. Figure 1 shows an example of the fence according to this embodiment. The fence 10 shown in Figure 1 as an example is constructed by engaging the four corners of the upper and lower horizontal rod-shaped bodies 1 with first engaging members 3 inserted into the end faces 21 of the left and right vertical rod-shaped bodies 1, and engaging the intermediate rod-shaped bodies 2, which are installed inside the left and right rod-shaped bodies 1, with the horizontal rod-shaped bodies 1 using second engaging members 4, which are not shown in the figure, to form a frame 7. Furthermore, grooves 20 with a concave cross-section having a predetermined width and depth are formed on the opposing surfaces of the left and right vertical rod-shaped bodies 1 and the intermediate rod-shaped body 2, and on the opposing surfaces of the upper and lower horizontal rod-shaped bodies 1. Specifically, grooves 20 with a concave cross-section are formed on the left and right rod-shaped bodies 1 and the upper and lower rod-shaped bodies 1 from the upper end to the lower end or from the left end to the right end on one inner surface, and grooves 20 with a concave cross-section are formed on the intermediate rod-shaped body 2 from the upper end to the lower end on both the left and right surfaces. Then, a blade 6 of a predetermined width is installed horizontally between the groove 20 in the concave cross-section on the right side of the left rod-shaped body 1 and the groove 20 in the concave cross-section on the left side of the intermediate rod-shaped body 2, and between the groove 20 in the concave cross-section on the right side of the intermediate rod-shaped body 2 and the groove 20 in the concave cross-section on the left side of the right rod-shaped body 1, thereby forming a fence 10. In this embodiment, the fence 10 is set to a height of approximately 1800 mm and a width of approximately 900 mm, but these values ​​are merely examples and can be set arbitrarily. Furthermore, the height can be set to about half and the width to about twice the original value.

[0010] Figure 2 shows an example of the upper and lower and left and right rod-shaped members that constitute the frame, where (a) is a front view and (b) is a cross-sectional view (including the end faces). Figure 2 shows an example of a rod-shaped body 1, which is a hollow rectangular prism made of synthetic resin. A groove 20 with a concave cross-section having a predetermined width and depth is formed along the longitudinal direction of the lower surface, which is not shown in the figure. Therefore, a rectangular opening 23 and a concave opening 22 having a predetermined width and depth are formed at the end face 21 of the rod-shaped body 1. The left and right vertical rod-shaped bodies 1 are set to a length of 1800 mm or 900 mm, and the top and bottom horizontal rod-shaped bodies 1 are set to a length of approximately 820 mm. The end faces are set to a size of 36 square mm, with a groove depth of 12 mm and an opening width of approximately 22 mm. However, these values ​​are just examples and can be set arbitrarily.

[0011] Figure 3 shows an example of an intermediate rod-shaped body installed vertically in the center of the frame. Figure 3(a) is a front view of the intermediate rod-shaped body, and Figure 3(b) is a cross-section of the intermediate rod-shaped body (including the end face). An example of an intermediate rod-shaped body 2 shown in Figure 3 is a hollow rectangular prism made of synthetic resin, and grooves 20 (not shown in the figure) with a concave cross-section having a predetermined width and depth are formed in the longitudinal direction of the two opposing upper and lower surfaces. Therefore, the end face 21 of the intermediate rod-shaped body 2 has a rectangular opening 24 with a recess in the center and recessed openings 22 on both sides thereof. The intermediate rod-shaped body 2 is set to a length of approximately 1734 mm or 880 mm, the end face 21 is 36 x 35 mm in size, the depth of the groove 20 portion of the concave cross section is 12 mm, and the opening width of the concave opening 22 is set to approximately 22 mm. However, these values ​​are just examples and can be set arbitrarily.

[0012] Figure 4 shows an example of the blade of this embodiment. The blade 6 shown in Figure 4 is an example of a strip made of synthetic resin, approximately 40 mm wide and 420 mm long, with notches 6a on both sides near the ends. These notches 6a are configured to accommodate projections 51b provided on the short side 51a of the rectangular hole 51 of the blade locking member 5, which will be described later.

[0013] Figure 5 shows an example of the first engaging member of this embodiment, where Figure 5(a) is a front view, Figure 5(b) is a left side view, Figure 5(c) is a right side view, Figure 5(d) is a top view, and Figure 5(e) is a bottom view. As shown in Figure 5, the first engaging member 3 of this embodiment is an L-shaped member in which two planar members of the same size as the end face 21 of the rod-shaped body 1 are perpendicular to each other. A protruding portion 33 with approximately the same width as the groove 20 of the concave cross-section of the rod-shaped body 1 is provided perpendicularly from one planar member 31 toward the other planar member 32, and a protruding member 33 with approximately the same width as the groove 20 of the concave cross-section of the rod-shaped body 1 is provided perpendicularly from the other planar member 32 toward the opposite direction from the one planar member 31. This member is made of synthetic resin. Therefore, the protruding members 33 can be inserted into the grooves 20 of the concave cross-sections of each of the orthogonal rod-shaped bodies 1, and the planar members 31 and 32 can be brought into contact with the end faces 21 of the rod-shaped bodies 1 to secure the rod-shaped bodies 1 to each other.

[0014] Figure 6 shows an example of the second engaging member of this embodiment, where Figure 6(a) is a front view, Figure 6(b) is a left and right side view, and Figure 5(c) is a top view. As shown in Figure 6, the second engaging member 4 in this embodiment is a synthetic resin member in which a pair of L-shaped members, each having a narrower width than the width of the groove 20 in the concave cross-section of the intermediate rod-shaped body 2, are perpendicular to each other. The two L-shaped members are arranged with one flat plate member 41 in series and the other flat plate members 42 in parallel, and the distance between the parallel flat plate members 42 is the same as the distance D between the grooves formed on both sides of the intermediate rod-shaped body 2, and the two are fixed together. Therefore, the intermediate rod-shaped body 2 and the lateral rod-shaped body 1 can be engaged by inserting the other flat plate portion 42 of the second engaging member 2 into each of the grooves 20 in the concave cross-section on both sides of the intermediate rod-shaped body 2 at the abutment point between the intermediate rod-shaped body 2 and the lateral rod-shaped body 1, and by pressing one of the flat plate portions 41, which is in series with the groove 20 in the concave cross-section of the lateral rod-shaped body 1, against it.

[0015] Figure 7 shows the blade locking member of this embodiment that locks both ends of the blade, where Figure 7(a) is a front view, Figure 7(b) is a back view, Figure 7(c) is a front view, and Figure 7(d) is a side view. The blade locking member 5, shown as an example in Figure 7, is a synthetic resin member having a width and height that fits into the grooves 20 of the concave cross-section of the vertical rod-shaped body 1 and the intermediate rod-shaped body 2. On both sides, protrusions 55 are formed in the longitudinal direction that fit into recesses 20a (described later) formed in the longitudinal direction on the inner surface of the groove 20 of the concave cross-section. The upper parts of both sides where the protruding ridges 55 are formed are bent downwards, forming a concave cross-section with an open surface at the bottom. The top surface 56 is provided with multiple rectangular holes 51 for securing the blade 6. Here, the length of the blade locking member 5 is set to approximately 1 / 4 of the fence height, You can make it longer or shorter than this, or you can cut a longer piece to adjust it to the desired length. Each of the rectangular holes 51 is formed at an angle that intersects with the protrusions 55, and multiple holes are arranged at equal intervals at a predetermined angle with respect to the longitudinal direction of the blade locking member 5. Here, the angle formed by the holes is set to less than 20 degrees. While the angle and position of the holes are limited by the length of the longer side of the rectangular hole, they can be arbitrarily set depending on the desired level of ventilation and light blocking. The angle can also be set to 0 degrees. Screw holes 57 are provided between the rectangular holes 51, and after fitting the blade locking member 5 into the groove 20 of the concave cross-section, screwing it in allows multiple blades 6 locked to the blade locking member 5 to be fixed together to the rod-shaped body 1 and the intermediate rod-shaped body 2.

[0016] Figure 8 shows a cross-section of a rectangular hole provided in the blade locking member. Figure 8(a) is a cross-sectional view of the rectangular hole from the short side, Figure 8(b) is a cross-sectional view of the rectangular hole from the long side, and Figure 8(c) shows the state in which the notch portion of the blade is locked into the rectangular hole. As shown in Figure 8, the rectangular hole 51 is formed at a position slightly higher than the opening surface 54 of the blade locking member, and a projection 51b is formed on the short side 51a of the hole 51, facing inward. Therefore, when the tip of the blade 6 is inserted into the rectangular hole 51, the short side 51a of the hole bends, causing the projection 51b to engage with the notch 6a, and the blade 6 is firmly fixed to the blade locking member 5.

[0017] Figure 9 shows the connection configuration of the four corners by the first connecting member. As shown in Figure 9, the surface of the vertical rod-shaped body 1 with the groove 20 in its concave cross-section is positioned inward, one flat member 31 of the first engaging member 3 is brought into contact with the end face 21 of the rod-shaped body 1, and the protruding member 33 perpendicular to the flat member 31 is inserted into the groove 20 in the concave cross-section of the vertical rod-shaped body 1. A screw is then inserted into the screw hole 33a of the protruding member 33 and screwed into the groove 20 in the concave cross-section of the vertical rod-shaped body 1. Next, the other flat member 32 of the first engaging member 3 is brought into contact with the end face 21 of the lateral rod-shaped body 1, and the protruding member 33 perpendicular to the other flat member 32 is inserted into the groove 20 of the concave cross-section of the lateral rod-shaped body 1. A screw is then inserted into the screw hole 33a of the protruding member 33 and screwed into the groove 20 of the concave cross-section of the lateral rod-shaped body 1. In this way, the four corners of the frame 7 can be joined simply, easily, and securely.

[0018] Figure 10 shows the connection configuration between the intermediate rod-shaped body and the lateral rod-shaped body by the second connecting member. As shown in Figure 10, the intermediate rod-shaped body 2 is positioned with the sides of the concave cross-section groove 20 facing left and right. The flat plate members 42 of the second engaging member 4, which are arranged in parallel and opposite directions, are inserted into the grooves 20 of the concave cross-section on each side, and screws are inserted into the screw holes 33a of each flat plate member 42 to screw them to the intermediate rod-shaped body 2. Then, the flat plate members 41, which are arranged in series, are fitted into the grooves 20 of the concave cross-section of the lateral rod-shaped body 1, and screws are inserted into the screw holes 33a of each flat plate member 41 to screw them in place. This allows the intermediate rod-shaped body 2 to be easily, readily, and reliably connected to the lateral rod-shaped body 1 of the frame 7. The procedure for assembling the fence 10 is as follows: a blade 6 is horizontally secured in each of the rectangular holes of a pair of blade locking members 5, and each blade locking member 5 is fitted into the groove 20 of the concave cross-section of the vertical rod-shaped body 1 and the groove 20 of the concave cross-section of one of the intermediate rod-shaped bodies 2, thereby screwing each blade locking member 5 into the groove 20 of the concave cross-section. Furthermore, a blade 6 is secured in each of another pair of blade locking members 5, and each blade locking member 5 is fitted into the groove 20 of the concave cross-section of the vertical rod-shaped body 1 and the groove 20 of the other concave cross-section of the intermediate rod-shaped body 2, thereby screwing each blade locking member 5 into the groove 20 of the concave cross-section. Then, the upper and lower ends of the intermediate rod-shaped body 2 and the vertical rod-shaped bodies 1 on both sides thereof are attached to the horizontal rod-shaped body 1 using the first attachment member 3 and the second attachment member 4, thereby efficiently assembling the fence 10.

[0019] Figure 11 is a cross-sectional view showing the blade locking member fitted into the groove. Figure 11(a) is a cross-sectional view showing the blade locking member fitted into the groove of the rod-shaped body, and Figure 11(b) is a cross-sectional view showing the blade locking member fitted into the grooves on both sides of the intermediate rod-shaped body. As shown in Figure 11, the left and right vertical rod-shaped bodies 1 that constitute the frame 7 are hollow rectangular timbers with concave cross-sectional grooves 20 having a predetermined opening width W and depth formed on one side in the vertical direction. The vertical intermediate rod-shaped body 2, positioned between the left and right rod-shaped bodies 1, has concave cross-sectional grooves 20 formed on both sides in the vertical direction via a narrow central opening 24. On both sides of the inner surface of the groove 20 in each concave cross-section, a recess 20a is formed in the longitudinal direction. The blade locking member 5 is a member of a predetermined length with a concave cross-section, having approximately the same width and height as the groove 20 of the concave cross-section, and has protrusions 55 formed in the longitudinal direction on the outer sides of both sides. Multiple rectangular holes 51 for locking the tip of the blade 6 are formed on the surface at an angle to the protrusions 55 and at equal intervals. When the blade locking member 5, which holds multiple blades 6, is pushed into the groove 20 with a concave cross-section, the protrusions 55 fit into the recesses 20a on the inner surface of the groove, so that the blade locking member 5 fits securely into the groove 20 with a concave cross-section of the rod-shaped body 1 or the intermediate rod-shaped body 2. Therefore, by inserting screws into the screw holes 57 provided between the rectangular holes 51 of the blade locking member 5 and screwing them in, the blades 6 can be securely fixed to the frame 7. [Industrial applicability]

[0020] This method is effective for easily and efficiently assembling border fences, which have multiple blades arranged at predetermined intervals horizontally within a rectangular frame, and louver fences, which have multiple blades arranged at predetermined intervals at an angle, by hand using mass-produced frame components and blades from a factory.
