Description

[Technical Field]

[0001] The present invention relates to a removable privacy panel that can be attached to an existing mesh fence to block views from outside. [Background technology]

[0002] Conventionally, privacy fences have been known that provide a certain degree of shielding and transparency to prevent the inside of a building or site from being seen from the outside, thereby protecting privacy and improving crime prevention. For example, a privacy fence made up of structural members arranged in the vertical and horizontal directions and lattice members arranged in parallel at predetermined intervals in the longitudinal direction on the front side of the structural members is known (see Patent Document 1). However, the Confucius surface blocks light, reducing light transmittance to less than 50%, which makes the site dark and creates a feeling of oppression similar to that of an airtight fence, reducing the comfort of the space. To address this issue, a privacy fence has been developed that uses a transparent or translucent light-transmitting material for the lattice material and allows it to slide from one end in the longitudinal direction (see Patent Document 2). Also, a lattice-shaped wire mesh fence has been developed in which a desired number of plate-shaped privacy panels are attached to the fence body in a detachable manner with bolts and nuts (see Patent Document 3). On the other hand, privacy fences have the drawback of being difficult to install and expensive to construct. Therefore, a mesh fence has been developed that consists of mesh panels made of vertical and horizontal wires and posts, and a fastening mechanism between the mesh panels and posts has been developed to simplify and facilitate the work, thereby reducing construction costs (Patent Document 4). However, while mesh fences are easy to install, inexpensive, and ideal for ensuring sunlight and ventilation, they can also block out other people from entering the property or house, making it difficult to ensure privacy if the property is small. On the other hand, privacy fences can ensure privacy, but they are expensive to install and make the property dark, creating a feeling of oppression. To address this issue, a removable hanger-type fence cover has been proposed (Patent Document 5), in which long sheets of veneer are arranged vertically, a batten is placed on the backside, and the fence cover, which has a hanging device attached to the batten, is hung on the batten of a metal fence or the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-36298 [Patent Document 2] Patent No. 5108340 [Patent Document 3] Publication No. 6-50613 [Patent Document 4] Patent No. 2747758 [Patent Document 5] Patent No. 6095609 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the fence cover described in Patent Document 5, the height at which it is attached to the metal fence bars is fixed depending on the vertical position at which the bars on the back are attached, which can result in a large gap between the base on which the metal fence is installed and the bottom end of the fence cover, as well as the problem that the fence cover is prone to coming off. In view of the above circumstances, the present invention aims to provide a removable privacy panel that can be hung on any horizontal strip of an existing mesh fence, can be firmly and easily fixed, and can also be easily removed, allowing the advantages of both a mesh fence and a privacy fence to be enjoyed as needed. [Means for solving the problem]

[0005] The removable privacy panel of the present invention comprises a pair of rectangular pillar members arranged side by side at a fixed interval, and a plurality of plate-like members arranged vertically, horizontally or diagonally between the rectangular pillar members, and is equipped with a privacy panel having longitudinal grooves formed on the back side opposite the front side of the rectangular pillar member on which the plate-like members are installed, and a hanging device that slides freely along each of the grooves and hooks onto horizontal lines, and is characterized in that the privacy panel is arranged side by side on top of a mesh fence that is erected and supported by pillar members with a plurality of horizontal lines that intersect with a plurality of vertical lines, and the hanging device that is hooked onto one of the horizontal lines of the mesh fence is fixed into the groove, thereby transforming the mesh fence into a privacy fence. The privacy panel is easy to assemble or can be produced in a factory. Simply place it on top of an existing mesh fence, slide the fasteners attached to the grooves of the rectangular pillars, and secure it in place so that it hooks onto one of the horizontal strips of the mesh fence. Installation is simple and convenient. It is also easy to remove, allowing it to be transformed into a privacy fence as needed. Furthermore, the groove is uniformly formed from the top to the bottom of the rectangular post member and has an opening width narrower than the width of the bottom surface, and the hanging device has a sliding part that engages with the opening edge of the groove and slides freely, and a hanging part that extends from the sliding part in an inverted U shape and hangs on the horizontal wire, the sliding part having a hole for fixing to the groove, and the hanging part having a screw hole on the opposing surface forming the inverted U for engaging the hung horizontal wire, so that the hanging device can be fixed in the desired position without coming off the groove, making it easy to install the privacy panel. Also, if the hanging device is engaged with the horizontal wire of the mesh fence with a screw, there is no risk of the privacy panel coming off the mesh fence and flying away. The panel has a height of approximately 600 mm to 1800 mm and a width of approximately 1000 mm to 2000 mm, and the plate-like member can be made of artificial wood or an aluminum alloy plate with multiple hollow portions formed in the longitudinal direction and coated with thermoplastic resin. Because privacy panels are exposed to the elements, they are prone to distortion and dimensional inaccuracies over time. Long plate-shaped components are particularly susceptible to these influences, and there is a risk of them breaking or separating from the rectangular column components. Therefore, if aluminum alloy, which is lightweight and highly weather-resistant, is used for the plate-shaped components and coated with a tough resin, they will be less susceptible to deterioration and will have a longer lifespan. Furthermore, if the rectangular column member is a hollow aluminum alloy member having an opening at the top end, one of whose sides is wider than the other by the thickness of the plate-like member, and an engaging portion that fits into the opening is formed on the back surface, and the plate-like member is provided with a lid with a canopy portion that covers the joint surface that abuts against the one side of the rectangular column member, the privacy panel will be lightweight and have a long lifespan. The privacy panel is superimposed on the mesh fence by abutting each of the square pillar members on the base on which the mesh fence is erected, and the sliding parts are slid into each of the grooves, and at least two of the hanging parts are hooked onto any one of the horizontal lines of the mesh fence and fixed to each of the grooves, and the hanging parts can be engaged with the horizontal lines with screws inserted into the screw holes of each of the hanging parts.This means that no large gaps are created between the base, such as a concrete block on which the mesh fence is installed, and the lower end of the privacy panel, and the privacy panel can be reliably supported by the mesh fence. [Effects of the Invention]

[0006] With the removable privacy panel of the present invention, a mesh fence can be easily transformed into a privacy fence simply by sliding a fastener into the groove provided in each of the square pillar members on both sides and hooking and fixing it to any horizontal strip of an existing mesh fence. Furthermore, if the privacy panel is large, it can be constructed using a plate-shaped member made of aluminum alloy coated with a thermoplastic resin such as ionomer, which will not deteriorate over the long term as it is strong and weather-resistant.

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the detachable privacy fence connecting member of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an example of a privacy panel of this embodiment, where FIG. 1(a) is a front view and FIG. 1(b) is a top view. As shown in an example in Figure 1, the privacy panel 1 has five plate-like members 3 arranged in parallel horizontally with a certain gap G between them, in front of each of a pair of parallel rectangular pillar members 2 arranged at a certain distance. The panels are then fixed to the rectangular pillar members 2 with screws so that their edges are flush with the wooden ends of the rectangular pillar members 2. The rectangular column member 2 is a hollow member made of aluminum alloy, and a lid 4 is fitted over the opening at the top end. Furthermore, a groove (not shown in the drawing) 5 having a uniform cross-sectional shape is formed on the rear side (back surface) of the prismatic member 2 to which the plate-like member 3 is fixed. The rectangular column member 2 used in this embodiment has a length of 800 mm and a thickness of 20 mm×450 mm, but the length may be, for example, 600 mm or 1800 mm. In addition, in this embodiment, five plate-like members 3 having a width of 120 mm and a length of approximately 1000 mm to 2000 mm are used, and are arranged with a gap G of 38 mm between them, but the dimensions do not necessarily have to be limited to those shown here. Furthermore, the arrangement of the plate-like members 3 does not have to be limited to the horizontal direction, but may be vertical, or may be arranged vertically and horizontally in a grid pattern, or may be diagonal. Furthermore, an arrangement combining these may also be used. Here, the privacy panel 1 of this embodiment may be made into a set of the necessary components, delivered to the construction site, and assembled on-site, or the finished product may be assembled in a factory and delivered to the site. The privacy panel 1 may be installed singly where needed, or may be placed side by side according to the length of the existing mesh fence, with the rectangular pillar members 2 of each privacy panel 1 in close contact with each other, and multiple fasteners 6 slid into the grooves 5 of each rectangular pillar member 2 to fasten to any horizontal strip of the mesh fence, thereby firmly securing each privacy panel 1 to the mesh fence.

[0009] Figure 2 shows an example of a rectangular column member, where Figure 2(a) is a perspective view and Figure 2(b) is a view showing an example of an upper end opening of the rectangular column member in an adjacently installed privacy panel. 2, the rectangular columnar member 2 of this embodiment is formed from a hollow aluminum alloy member, and the width of one of the two side surfaces, 2c, is larger than the width of the other side surface, 2d, by the thickness of the plate-like member 3. An opening 2d is provided at the upper end. Here, the front 2a and back 2b of the rectangular pillar member 2 are 20 mm wide, one side 2c is 45 mm wide, and the other wider side 2d is 56 mm wide. Therefore, the edges of the plate-like members 3 abut against the wider side 2d, so that the wide side surfaces 2d of adjacent privacy panels 1 can be fitted together perfectly without any gaps. In this embodiment, the rectangular pillar member 2 has sides with different widths, with one side being the wider side 2d, but the widths of the sides may be the same. However, care must be taken to ensure that the edges of the plate-like members are installed flush with the edge of the rectangular pillar member. If they are not flush, gaps will sometimes appear between the privacy panels and sometimes not, which will not look good. A groove 5 is formed on the back surface 2b on which the privacy panel 1 is installed. The groove 5 is formed across the entire width of the rear surface 2b, over a 2.8 mm portion of the side surface 2c (and side surface 2d). Here, the bottom width BW of the groove 5 is set to 18.4 mm, the opening width OW to 14.4 mm, and the depth to 2.0 mm. Since the opening width OW is narrower than the bottom width BW, the fastener 6 is engaged with the opening periphery 5E of the groove 5 and can slide freely up and down without coming off the groove 5. Here, in this embodiment, the groove 5 is provided with an opening periphery 5E narrower than the bottom width BW, but the opening periphery 5E is not necessarily required. However, if the opening periphery 5E is provided, the fastener 6 will not come off the groove 5, making the work easier. The numerical values ​​shown here are merely examples and are not necessarily limited to these values.

[0010] Figure 3 shows other examples of privacy panels, where Figure 3(a) shows a privacy panel in which plate-shaped members are arranged vertically, Figure 3(b) shows a privacy panel in which plate-shaped members of different widths are arranged horizontally, Figure 3(c) shows a privacy panel in which plate-shaped members are arranged vertically and horizontally in a grid pattern, Figure 3(d) shows a privacy panel in which plate-shaped members are arranged diagonally, and Figure 3(e) shows a privacy panel in which the top row has plate-shaped members arranged as shown in Figure 3(d) and the middle and bottom rows have plate-shaped members arranged as shown in Figure 1(a). The privacy panels are placed alongside the almost completely transparent mesh fence, with the aim of preventing the interior from being seen from the outside, but they must be able to withstand the wind pressure of the strong winds that are expected to blow during the season. Also, since humidity increases when air circulation is restricted, it is necessary to allow some air circulation. Therefore, rather than completely concealing the interior, some gaps are necessary. Therefore, it is necessary to make it difficult to see inside from the outside, while leaving some gaps and also considering aesthetics.

[0011] Taking these points into consideration, Figures 3(a) to 3(e) show examples of arrangements in which plate-like members are arranged vertically, horizontally, and diagonally between rectangular columnar members, but the present invention is not necessarily limited to these examples. However, the size of the privacy panel 1 is assumed to be approximately 600mm to 1800mm in height and 1000mm to 2000mm in width. Therefore, the length of the rectangular column member is approximately 600mm to 1800mm, and the length of the plate-like member is approximately 1000mm to 2000mm. Furthermore, in order to make one of the two side surfaces of the rectangular pillar member 2 wider than the other, it is necessary to form the panel from a metal material or resin. The privacy panel 1 is exposed to the outside air, so it is preferable to use an aluminum alloy, which has high weather resistance and is resistant to deformation, discoloration, deterioration, and other changes in quality. Artificial wood can be used for the plate-shaped member 3, but if the length is about 2000 mm, it is preferable to use an aluminum alloy plate with multiple hollow sections formed in the cross section and coated with thermoplastic resin, from the standpoint of weight and strength. The aluminum alloy plate-like member 3 used in this embodiment is a rectangular parallelepiped formed by die-casting, with four spaces formed inside and the outer periphery coated with ionomer resin. Ionomer resins have excellent colorability, strong mechanical properties, elasticity and flexibility, resistance to cracks and fissures, and good abrasion resistance, making them suitable for use as components of fences exposed to the outdoors. For example, there is a product with a width of 120 mm, a thickness of 12 mm, an aluminum alloy portion having a thickness of 1.2 mm, a space partition having a thickness of 0.9 mm, and an ionomer resin coating having a thickness of 1.2 mm, but there is no need to be limited to these numerical values.

[0012] 4A and 4B are diagrams showing the rear surface of the lid of the prismatic member, with FIG. 4A being a perspective view and FIG. 4B being a plan view. The lid portion 4 shown in Figure 4 has a portion 4a that closes the opening of the rectangular column member 2 to prevent rain and foreign objects from entering the interior, and a canopy portion 4b that covers from above the area where the plate-like member 3 abuts against and is fixed to the wide side surface 2d of the rectangular column member 2. The portion 4a that closes the opening has an engagement portion 4c formed on the back surface thereof that fits into the opening 2d to make it difficult for the lid 4 to come off, and an eave portion 4b extends from that portion. The lid 4 may be made of stainless steel or may be molded from resin. Here, the lid portion 4 of this embodiment includes a portion 4a that closes the opening and an eave portion 4b, but the eave portion 4b is not necessarily required.

[0013] FIG. 5 shows an example of a fastener, where FIG. 5(a) is a front view, FIG. 5(b) and (c) are left and right side views, FIG. 5(d) is a plan view, and FIG. 5(e) is a perspective view. As shown in Figure 5, the fastener 6 has a sliding portion 6a that slides freely in the groove 5, and a hanging portion 6b that extends from the sliding portion 6a in an inverted U shape and hooks onto the wire, and the width of the sliding portion 6a is smaller than the bottom width BW of the groove 5 and larger than the opening width OW. The sliding portion 6a has a hole 6X, which can be fixed at any position in the groove 5 with a screw to secure the hook 6. The hook 6b also has a screw hole 6Y on each of its opposing inverted U-shaped surfaces, and the screw hole 6y on one surface is internally threaded. Therefore, by inserting a male screw into the screw hole 6Y, the hook 6b can be fixed so that it does not come off the wire W to which it is hooked.

[0014] FIG. 6 is a view showing the side surface and opening of the prismatic member to which the fastener is fixed. In FIG. 6, the broken lines indicate the bottom surface and opening edge 5E of the groove 5, which are not shown in the drawing. As shown in Figure 6, the sliding portion 6a is engaged with the opening edge 5E of the groove 5, so the hanging device 6 can move freely up and down along the groove 5 on the back surface 2b of the rectangular pillar member 2 without coming off the groove 5. Therefore, it can be hung on any horizontal wire W of the mesh fence. After the hanging portion 6b is hung on the horizontal wire W of the mesh fence, the sliding portion 6a is fixed to the groove 5 with a screw or the like. Furthermore, a screw is inserted into the hanging portion 6b to lock the hanging portion 6b so that it does not come off the horizontal wire W. In this way, the hanging device 6 is engaged with the opening edge 5E and slides freely without coming off the groove 5, so the square pillar member 2 of the privacy panel 1 can be erected on a base such as a concrete block on which a mesh fence is erected, and the hanging device 6 can be fixed in a position where it can be hooked onto one of the horizontal wires W. Therefore, the privacy panel 1 can be installed without creating a gap between the square pillar member 2 and the base. Here, the number of fasteners 6 to be installed does not need to be limited to one in the same groove 5, but one or more may be installed in each groove 5 of each rectangular column member 2 and hung on different horizontal wires W. If they are installed, for example, on the upper and lower tiers of each rectangular column member 2, the privacy panel 1 can be more firmly fixed to the mesh fence. The privacy panel 1 of this embodiment is relatively lightweight even though the plate-like member 3 is long, since it is made of aluminum alloy, and can be easily attached to the mesh fence. [Industrial Applicability]

[0015] Existing mesh fences can be easily and inexpensively transformed into privacy fences or reverted to mesh fences by simply using them as they are. [Explanation of symbols]
