Description

[Technical field]

[0001] The present invention relates to a gap-adjusting spacer made of round bamboo, and in particular to a gap-adjusting spacer used in a bamboo blind fence unit in which multiple round bamboos are arranged side by side in the vertical direction. [Background technology]

[0002] Traditionally, bamboo fences have been installed in gardens and on sites for the purposes of fencing, dividing areas, screening areas, and preventing intrusions, and in recent years, artificial bamboo fences that mimic the texture of natural bamboo have been widely used to decorate indoor and outdoor garden walls, fences, corridors, etc. The artificial bamboo panels and round bamboo used in artificial bamboo fences are made from weather-resistant synthetic resin, and are finished in a way that compares favorably with natural bamboo in terms of shape and color. In addition, because they are made from synthetic resin, they have the advantage of being less susceptible to corrosion, discoloration, and insect damage than natural bamboo.

[0003] As an artificial bamboo fence that can be constructed more easily, one that uses artificial bamboo panels called "Real Fit," which more realistically reproduces the delicateness and shading unique to bamboo, is on sale (see, for example, Non-Patent Document 1). Also, an artificial bamboo panel with a bamboo pattern on the front panel that is suitable for small-scale and diverse production has been disclosed (see, for example, Patent Document 1).

[0004] As shown in Figure 6, the above artificial bamboo fences are called Kenninji-gaki 60, Misu-gaki 61, Otsu-gaki 62, Shimizu-gaki 63, Yotsume-gaki 64, Kinkakuji-gaki 65, Ryoanji-gaki 66, etc., depending on their design. For example, Kenninji-gaki 60 is a panel-like design that looks like natural bamboo cut into pieces about 4 cm wide lined up without any gaps, and is a fence designed to block views, making it an elegant bamboo fence that will brighten up the scenery of ordinary homes and commercial facilities.

[0006] [Non-Patent Document 1] "Real Fit (Globen Co., Ltd.)" [Searched on July 5, 2022], Internet<URL:http: / / www.globen.co.jp / product-a / take.html> Summary of the Invention [Problem to be solved by the invention]

[0007] By the way, a bamboo fence called Misare-gaki is a type of bamboo fence made by stacking round bamboo stalks, each with a diameter of 22 mm, one by one, and is characterized by the fact that small gaps are created at the bamboo joints, allowing a slight see-through of what is behind. The round bamboo used for Misare-gaki is made of resin and is characterized by its joint-setting technique, and therefore the tolerance is adjusted during extrusion molding, but there is a limit to how constant the diameter of the resin round bamboo can be, and it is unavoidable that some round bamboo will have a tolerance (for example, a diameter of 21.5 to 22.5 mm).

[0008] In such cases, when trying to arrange multiple bamboo pieces vertically, the resulting height (e.g. 590mm) often differs from the desired height (e.g. 600mm). Also, when bamboo pieces with different diameters are used, the bamboo pieces are not arranged at equal intervals vertically, which impairs the design.

[0009] To solve this problem, currently the height is adjusted by fixing both ends of the bamboo with screws to a C-channel with a roughly C-shaped cross section into which the ends are inserted. Since there is no fastening at both ends, which do not originally have standoffs, the kumiko tend to sag, and there was a need for auxiliary parts that would allow for height adjustment. However, adjusting the height of the bamboo by fixing with screws is time-consuming and requires high skill, which makes the installation of the bamboo blind fence time-consuming and labor-intensive.

[0010] The present invention was made in consideration of the above problems, and aims to provide a gap adjustment spacer that can easily adjust the gap between round bamboos without hassle, even when installing an artificial bamboo fence consisting of multiple round bamboos lined up side by side. It also aims to provide an artificial bamboo fence unit that can stabilize the product dimensions after construction of the artificial bamboo fence unit (especially the bamboo blind fence unit). [Means for solving the problem]

[0011] In order to achieve the above-mentioned objective, the present invention is a gap adjustment spacer for round bamboo used in artificial bamboo fences to adjust the gap spacing between multiple round bamboos arranged side by side, the gap adjustment spacer having an approximately Y-shaped vertical cross section.

[0012] It is preferable that this gap adjustment spacer comprises a flat portion formed on one surface thereof, an insertion portion extending in a direction opposite to the flat portion and having a thickness enabling it to be inserted into the gap between the juxtaposed round bamboos, and a curved surface formed on the side of the insertion portion and having a curved shape that follows the curvature of the round bamboo.

[0013] In this round bamboo gap adjustment spacer, it is preferable that the flat surface be formed with a semi-cylindrical recess through which a banrobe, an artificial palm rope, can be inserted.

[0014] In order to achieve the above-mentioned object, the present invention provides an artificial bamboo fence unit comprising a number of posts erected from the ground, a C-channel having an approximately U-shaped horizontal cross section and attached in an up-down direction to the opposing faces of the posts, a furring strip suspended horizontally between the C-channels, a number of lattice members made of round plastic bamboo that are arranged in parallel on the furring strips and have both ends fixed to the C-channel, a number of standing members made of round plastic bamboo that are attached in an up-down direction to both ends of the lattice members, and a gap adjustment spacer for adjusting the gap spacing between the lattice members.

[0015] In this artificial bamboo fence unit, it is preferable that the gap adjustment spacers are inserted into the gaps on the left and right ends of the kumiko, which correspond to the locations where the uprights are attached.

[0016] In this artificial bamboo fence unit, it is preferable that the gap adjustment spacers are arranged at equal intervals. Effect of the Invention

[0017] This invention is a gap adjustment spacer for adjusting the gap between multiple round bamboos arranged side by side in an artificial bamboo fence, and the gap adjustment spacer has a vertical cross section that is approximately Y-shaped. By using this gap adjustment spacer, it can be easily installed during or after the bamboo fence unit is assembled. Even when installing an artificial bamboo fence consisting of multiple round bamboos arranged side by side, the gap between the round bamboos can be easily adjusted without any effort.

[0019] (Embodiment) The round bamboo gap adjustment spacer (hereinafter referred to as the gap adjustment spacer) according to the embodiment of the present invention will be described with reference to the drawings. An artificial bamboo fence is made by fixing artificial bamboo (artificial bamboo panels or artificial round bamboo) to posts erected from the ground, etc., and can create an emotional landscape while reproducing the fineness and flexibility of bamboo with plastic resin. In addition, an artificial bamboo fence can ensure the strength as a fence and the functionality as a shielding panel, and is an enclosure installed at the boundary between a house or a site and other things for the purpose of dividing it, hiding it, and preventing intrusion.

[0020] The artificial bamboo fence unit according to this embodiment is specifically a bamboo blind fence unit. This bamboo blind fence unit is a round bamboo type artificial bamboo fence that has both moderate shielding and high expandability, and is popular in both Japanese and Western styles for its moderate gaps that are partially created at the height of the nodes at the boundary between neighboring houses.

[0021] First, the overall structure of the blind fence unit according to the present invention will be described with reference to Fig. 1. The blind fence unit 10 includes a number of posts 11 erected from the ground, C-channels 12 that have a horizontal cross section of a roughly U-shape and are attached to the opposing faces of the posts 11 along the vertical direction, furring strips 13 that are suspended horizontally between the C-channels 12, a number of lattice members 14 that are resin round bamboos that are arranged in parallel on the furring strips 13 and whose both ends are supported by the C-channels 12 with screws or the like, a number of standing members 15 that are resin round bamboos that are attached to the front and back sides along the vertical direction at both ends of the lattice members 14, and a gap adjustment spacer S for adjusting the gap between the lattice members 14. The lattice members 14 and standing members 15 are resin round bamboos, and in the blind fence unit 10, those with a seventh dimension (diameter 22 mm) are used, and are called lattice members 14 (horizontal) or standing members 15 (vertical) depending on the direction. The final decoration is the Banrobe 16, an artificial palm rope made of polypropylene.

[0022] Next, the gap-adjusting spacer S used in the bamboo blind unit 10 will be described with reference to Fig. 2. The gap-adjusting spacer S is a member for adjusting the gap between multiple round bamboos (mutin pieces 14 in Fig. 1) arranged side by side in the horizontal direction. The material of the gap-adjusting spacer S is preferably soft polyvinyl chloride, which is lightweight and strong, and the color is preferably transparent so as not to stand out.

[0023] 2(a), the gap adjustment spacer S has a substantially Y-shaped vertical cross section, and comprises a flat portion S1 formed on one surface thereof, an insertion portion S2 extending in a direction opposite to the flat portion S1 and having a thickness allowing it to be inserted into the gap between adjacent kumiko (round bamboo) pieces 14, and a curved surface S3 formed on the side of the insertion portion S2 and conforming to the curvature of the round bamboo 14. It also comprises a recessed portion S4 having, for example, a semi-cylindrical shape through which the ban lobe 16 is inserted. Note that the surfaces of the curved surface S3 and the recessed portion S4 do not necessarily have to be curved, and for example, multiple flat surfaces may be arranged in a curved shape.

[0024] Next, the size of the gap adjustment spacer S will be described with reference to Fig. 3. The gap adjustment spacer S has a height of 16 mm and a width of 12 mm as seen from the front in Fig. 3(a), a thickness of the insertion portion S2 of 2 mm, and a depth of 16 mm as seen from the side in Fig. 3(b). The flat surface of the flat portion S1 has a width of 2 mm and a depth of 16 mm, and the recessed portion S4 is a semi-cylindrical recess with a radius of the semi-cylinder of, for example, 4±1 mm.

[0025] Next, a method of installing the bamboo blind unit 10 using the gap adjustment spacer S will be described with reference to FIG. 4. As mentioned above, the tolerance of the round bamboo 14 that constitutes the bamboo blind unit 10 is adjusted during extrusion molding, but there is a limit to making the diameter of the resin round bamboo 14 constant (diameter 22 mm), and some round bamboos have tolerances (for example, diameter 21.5 to 22.5 mm). In this case, if multiple kumiko 14 are arranged side by side, the height dimension of the bamboo fence will vary, and a surface will be created with a height dimension (for example, 590 mm) that deviates from the desired height (for example, 600 mm). In addition, the beautiful design of adjacent kumiko 14 arranged side by side at equal intervals in the vertical direction cannot be maintained.

[0026] Therefore, in this embodiment, at the time of construction, first, both ends of multiple muntins 14 are assembled into the C channel 12, and then the height size is adjusted using the gap adjustment spacer S, and the gap interval is adjusted to be constant. Specifically, if there is a deviation in the height dimension when the muntins 14 are arranged vertically in parallel during construction (for example, 10 mm), the height can be adjusted by +2 mm each time the gap adjustment spacer S is inserted, so the gap adjustment spacer S is inserted into the gap between adjacent muntins 14 according to the size of the deviation (for example, in the case of a deviation of 10 mm, five gap adjustment spacers S are inserted). During construction, the deviation in height between adjacent bamboo fences is a hassle for the construction craftsman and also makes the fence look bad. This was devised to reduce these problems.

[0027] In addition, Fig. 4(b) shows the case where one gap-adjusting spacer S is inserted between every two muntins 14. Also, as shown in Fig. 4(c), the gap-adjusting spacers S are inserted into the gaps on the left and right ends of the muntins 14 corresponding to the locations where the standing bars 15 are attached so that the gap-adjusting spacers S cannot be seen from the outside. Also, as shown in Fig. 4(a), the flat surface S1 of the gap-adjusting spacer S contacts the surface of the standing bar 15. In addition, since the gap-adjusting spacers S are made of soft polyvinyl chloride, they are not slippery and will not come off even if the bamboo fence panel is turned upside down or shaken after the bamboo blind unit 10 is completed.

[0028] Next, an example of installation of the blind fence unit 10 using the gap adjustment spacer S will be described with reference to Fig. 5. In the case shown in Fig. 5, the positions for inserting the gap adjustment spacer S are not decided at the construction site, but the positions for inserting the gap adjustment spacer S are made uniform from the beginning. Also, since the gap adjustment spacer S has a recessed portion S4, even if it is necessary to insert the ban rope 16 into the position where the gap adjustment spacer S is inserted, the ban rope 16 can be inserted as is.

[0029] As explained above, the gap-adjusting spacer S is used in an artificial bamboo fence to adjust the gap between multiple round bamboos arranged side by side, and has a generally Y-shaped vertical cross section with a flat section S1 formed on one side, an insertion section S2 that extends in the direction opposite the flat section S1 and has a thickness that allows it to be inserted into the gaps between the round bamboos 14 arranged side by side, and a curved surface S3 formed on the side of the insertion section S2 that follows the curvature of the round bamboos 14. With this configuration, the height dimension of the round bamboos 14 can be adjusted by inserting the gap-adjusting spacer S between the round bamboos 14.

[0030] In this case, (1) the gap adjustment spacer S is simply inserted into the gaps in the kumiko 14, which is extremely simple compared to the conventional work of fixing both ends of the kumiko 14 to the C channel 12 with screws to adjust the height. (2) The gap adjustment spacer S is made of soft polyvinyl chloride, so it is not slippery and will not come off during delivery. (3) The gap adjustment spacer S is transparent, so it is not noticeable. It can also be inserted into the gaps at both ends and under the channel. As a result, the product dimensions of the blind fence unit 10 are stabilized, a beautiful design is achieved, and the construction time for the blind fence unit 10 can be dramatically reduced compared to the conventional method.

[0031] In addition, the present invention is not limited to the configuration of the above embodiment, and various modifications are possible within the scope of the invention. For example, the gap adjustment spacer S can be used not only when multiple round bamboos are arranged in a vertical direction, but also when multiple round bamboos are arranged in a horizontal direction. Furthermore, the size of the gap adjustment spacer S is not necessarily limited to the above, and it goes without saying that it can be adjusted appropriately depending on the application.
