Description

  TECHNICAL FIELD The present invention relates to an aluminum plate member for producing a knitted fabric by combining a plurality of members.

  Conventionally, as a work that brings out a Japanese-style flavor, for example, when knitting a rattan or a tapestry, it is known to use a bamboo ladder as a bamboo work. In particular, so-called Hiratake higashi etc. which use the skin side of bamboo as a design surface of bamboo work are often used. A bamboo arch is curved in an arc shape in the width direction because it is formed by dividing a cylindrical bamboo in the fiber direction, so the design surface is three-dimensional and gives an aesthetic appearance. Moreover, when producing one bamboo work, the thing of uniform width and thickness is preferred for the bamboo stick used for this.

  And, as a bamboo work woven with a bamboo ladder, for example, a weir having a bottomed shape opened upward and capable of containing a plant is disclosed (Patent Document 1).

  However, in the thing of the said patent document 1, since the bamboo elbow is curving, it becomes concave shape in the opposite surface (back surface) of a design surface. Therefore, for example, when the back surface is turned inward and the container is knitted, the stored item or the like may be clogged or caught in the recess. In addition, since a bamboo stick is manufactured using a natural material, bamboo, and cutting it further, it requires skilled technology to uniformly adjust the width and thickness.

  The present invention has been made in view of such a point, and an object thereof is to devise the shape of a material so as to make it possible to eliminate a defect due to the concave portion of the bamboo hinge while making the imitation of the bamboo hinge made of another material. It is in.

FIG. 7 is a view corresponding to FIG. 6 (3) according to Embodiment 2 of the present invention.

  Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its applications or its uses.

(Embodiment 1)
As shown in FIG. 1, an aluminum plate material for knitting having a long shape and flexibility in its length direction (hereinafter simply referred to as aluminum plate material) 10 is, for example, as shown in FIG. It is a material for producing a knitted fabric such as a bag K shown.

  The aluminum plate member 10 has a flat surface 11 formed to extend flat on one side, and an arc on the other side opposite to the flat surface 11 so that the center in the width direction bulges relative to the flat surface 11 An arc surface 12 is drawn and extended.

  Further, vertical wall surfaces 13 are provided at both ends in the width direction. The cross-sectional shape of the flat surface 11, the arc surface 12 and the vertical wall surface 13 is configured such that the center in the width direction is relatively thick and the both sides in the width direction are thin. The depression angles of the flat surface 11, the arc surface 12 and the vertical wall surface 13 are respectively chamfered with a slight curved surface.

  And although color does not appear in a drawing, aluminum board material 10 is dyed the whole surface in the dark blue.

  In the first embodiment, the width is set to 3 mm, the maximum thickness of the central portion in the width direction is set to 0.3 mm, and an arc surface of the arc surface 12 is drawn with a curve having a radius of 15 mm. This dimension is merely an example, and may be any dimension depending on the size, shape, etc. of the knitted fabric to be produced. However, if it is too thick, it will be difficult to bend when knitted, and if it is too thin, it will be easy to bend but the shape maintainability will deteriorate, so it is preferable to set the width to 2 mm to 20 mm and the thickness to 0.3 mm to 0.5 mm.

  Although the detailed structure will be described later, the surface of the aluminum plate 10 is provided with an alumite-treated alumite layer 20, and the surface of the alumite layer 20 is provided with a dyed treatment layer 30. The pore 22 is sealed in a state in which the pores 22 are impregnated with the dye (see FIG. 6).

  Next, a state in which a plurality of aluminum plate members 10 are combined to produce a knitted fabric will be described. In the following, the aluminum plate member 10 extending in the vertical direction shown in the enlarged view of FIG. 3 will be described as the vertical plate member 10 a and the one extending in the horizontal direction as the horizontal plate member 10 b.

  As shown in FIG. 2 and FIG. 3, a plurality of aluminum plate members 10 having the same width and thickness are mesh-knitted to produce a weir K as a knitted fabric. Mesh knitting is, for example, a technique generally used as a knitting method such as bamboo work using a bamboo hibera. Specifically, the vertical plate 10a and the horizontal plate 10b are made to cross at right angles, and several or more yarns are cut. It is a technique of knitting while closing eyes like alternately. You can make a mesh pattern by shifting your eyes for each row. Here, an example is shown in which three yarns are woven so as to go beyond three, but the number of excesses and the number of yarns may be changed as appropriate.

  At this time, the vertical plate member 10a and the horizontal plate member 10b are knitted such that the arc surface 12 is the front side, that is, the design surface of the weir K, and the flat surface 11 is the reverse side, that is, the inner surface of the weir K.

  Then, as shown in FIG. 4, on the front side, the circular arc surface 12 crosses in the vertical and horizontal directions to form a mesh pattern, so that natural shadows are produced as if they were woven with a natural bamboo ladder and three-dimensional Create an aesthetic appearance.

  On the other hand, on the back side, the flat surface 11 crosses lengthwise and crosswise to form a mesh pattern. By the way, in the case of a bamboo cub, due to the nature produced by breaking natural bamboo along a fiber, the surface of the skin swells and the opposite surface (back side) has a concave shape. And usually, when a bulging surface is used as a design surface, the back surface is knitted using a concave surface. In this case, for example, when the knitted fabric is a basket such as an accessory case, there is a risk that the stored accessory or the like may be clogged in the recess, may be caught in the edge of the recess, or may lack stability.

  As such, according to the present invention, since both the vertical plate 10a and the horizontal plate 10b have the flat surface 11 on the back side, in the manufactured knitted fabric such as a rattan, the contents stored in the same may be clogged or caught. Can be reduced, and the stability of the contents can be improved.

  That is, by using an aluminum material to simulate a bamboo tooth, the degree of freedom in processing is improved, and the dimensions can be easily made uniform. In addition, since the degree of freedom in the shape is also improved, it is possible to form the flat surface 11 by eliminating the recess formed in the bamboo ladder, and the functionality is improved. On the one hand, it is possible to embody the natural shadow by the bamboo hig by means of the circular arc surface 12.

  In addition, if the thickness of the aluminum plate 10 is uniformly reduced, there is a concern that the aluminum plate 10 may be broken or broken when it is bent for weaving. In the present invention, the center in the width direction is relatively Because of the thick cross-sectional bow shape, high strength can be achieved as compared to the case of uniformly thin formation.

  Furthermore, since the entire surface of the aluminum plate material 10 is dyed with the dye 30x (details described later) for indigo dyeing, the modern impression of metal and the Japanese impression of indigo that is a traditional Japanese color Together, it can produce a stylish texture.

  Next, a method of manufacturing the aluminum plate member 10 and a detailed structure thereof will be described based on FIGS. 5 and 6. The alumite layer 20 and the micropores 22 shown in FIG. 6 are not shown in an actual size ratio but are exaggerated for clarity. Also, in practice, the boundary between the material 10x of the aluminum plate member 10 and the alumite layer 20 is not clearly distinguished by lines, and the alumite layer 20 is not represented by an even thickness. For convenience of explanation, it shall be distinguished by a line.

  As shown in the first step S1 of FIG. 5, the surface of the material 10x of the pretreated aluminum plate material 10 is alumite-treated to form an alumite layer 20 on the surface of the material 10x. The formation method of the alumite layer 20 uses a well-known method. For example, an alumite layer 20, which is an oxide film, is formed on the surface of the material 10x by an alumite treatment in which the material 10x is used as an anode in a bath of electrolyte solution and current is passed between the anode and the negative electrode. When the alumite layer 20 is formed in this manner, as shown in FIG. 6A, a large number of micropores 22 opened in the surface of the alumite layer 20 are formed. The micropores 22 are pores with a diameter of nanometer, for example, about 5 to 20 nm in diameter.

  In addition, as a condition of alumite processing, when processing temperature is low, the necessary alumite layer 20 is hard to be formed. On the other hand, when the treatment temperature is high, the hardness is reduced and the film is easily scratched. Therefore, treatment at normal temperature is preferable, and 15 ° C. to 30 ° C. is more preferable. If the treatment time is too short, the necessary alumite layer 20 is difficult to form. On the other hand, when the treatment time is long, the film thickness of the alumite layer 20 to be attached is increased, and the corners of the aluminum plate 10 are easily chipped. It is preferable to do. The thickness of the alumite layer 20 is 3 μm to 25 μm, preferably 5 μm to 20 μm, because the corner is chipped if the thickness is too large and the hardness is insufficient for the alumite layer 20 if it is too thin. preferable.

  Next, in the second step S2, the fine holes 22 are subjected to a dyeing process in which a dye 30x for twill dyeing is inserted. Specifically, for example, the material 10 x having the alumite layer 20 formed on the surface is subjected to a dyeing process by immersion treatment in which the material 30 x is immersed in a tank where the dye 30 x is stored for a predetermined time. As a result, as shown in FIG. 6 (2), the dye 30 x enters each of the micropores 22, and the dyed layer 30 is formed on the surface of the alumite layer 20.

  As described above, since the dye 30x can be introduced into the micropores 22 and subjected to the dyeing process, the aluminum plate member 10 dyed in a desired color can be obtained. In particular, by using the dye 30x for indigo dyeing, it is possible to exude a Japanese-likeness while being made of metal, and to embody the texture that blends traditional and modern.

  As the dye 30x for eyebrow dyeing, it is possible to use natural leaf green leaves, chemically synthesized indigo dye, and the like. The method of the staining treatment is not limited to the immersion treatment described above, and any other method may be used as long as it can be stained. In addition, the dye 30x is not limited to the use for indigo dyeing.

  Next, in the third step S3, the fine pores 22 of the alumite layer 20 having the dyed layer 30 formed on the surface, that is, the alumite layer 20 in which the dye 30x is intruded by the dyeing process, are sealed. By performing the sealing process, as shown in FIG. 6 (3), the opening of the micropore 22 is closed.

  In this sealing process, a large number of micropores 22 opened toward the surface side are closed from the surface side. Specifically, there may be mentioned, for example, a known water vapor method, a boiling water method, a hydration treatment such as a nickel acetate method, and the like. Hydrates generated by such hydration treatment block the openings of the micropores 22.

  Since the opening of the micropores 22 is closed in the state where the dye 30x enters the micropores 22 of the alumite layer 20 by such sealing treatment, the aluminum plate member 10 which is hard to lose color is obtained.

  During the dyeing process described in the second step S2, the dye 30x not only enters the fine pores 22 but also adheres to the surface part between the fine pores 22, but after the sealing process is performed, that part May not leave dye 30x. However, since the micropores 22 of the alumite layer 20 are innumerably dispersed on the surface of the aluminum plate member 10 in nanometer units, the dye 30x is made to enter the micropores 22 of the alumite layer 20 to perform sealing treatment. Thus, the entire surface of the aluminum plate 10 appears as if it were dyed. Therefore, in the present invention, the dye 30x attached to the surface portion between the micropores 22 may or may not be left, and any state is referred to as the dyed layer 30.

  By using a plurality of aluminum plate members 10 obtained in this manner, the front and back sides are aligned and knitted to obtain a three-dimensional pattern by the circular arc surface 12 on one side, and a flat surface on the other side. A flat pattern by 11 is obtained. Further, for example, when the accessory case or the like is knitted with the arc surface 12 side as a design surface, a three-dimensional pattern in which a plurality of combined arcs are drawn appears on the outside. In addition, since the inner side is a flat surface, it is possible to reduce clogging and sticking of the contents and to improve the stability of the contents. Moreover, when tapestry and a coaster are knitted, it is possible to secure a large contact area with respect to the installation surface by setting the surface on the wall side (mounting side) to the flat surface 11 and to stabilize the installation state. it can.

  In the present embodiment, an example in which the plurality of aluminum plate members 10 are knitted by mesh is described, but the present invention can be applied to any other knitting method. For example, it may be used for sixth knitting, fourth knitting, crochet knitting, turtle shell knitting, ring opening knitting, yarn knitting, twist knitting, chrysanthemum knitting, etc. It may be used for hemp leaf knitting, crutch knitting, etc. However, in order to take advantage of the circular arc surface 12 and the flat surface 11, it is preferable to align and knit the front and back.

  In addition, examples of the knitted fabric to which the aluminum plate material 10 is applied include other handicrafts, crafts, ornaments, daily goods, and the like. Specifically, it can be applied to, for example, a rattan, a figurine, a rug, a picture, a drawing, a picture frame, a flower vase and the like.

Second Embodiment
The second embodiment will be described based on FIG. In the description of the second embodiment, only the portions different from the first embodiment will be described, and the description of the same portions will be omitted.

  In the second embodiment, in order to improve the slip of the aluminum plate member 101, the lubricating layer 50 is provided on the outermost surface of the aluminum plate member 101 which is the outermost side. The lubricating layer 50 is provided to coat the surface of the alumite layer 20 by, for example, applying or spraying a lubricant such as a silicon-based lubricant on the surface of the alumite layer 20.

  Instead of applying or spraying a lubricant on the surface of the alumite layer 20 to form the lubricating layer 50, the lubricating layer 50 may be formed by another method. Specifically, for example, the lubricating layer 50 may be formed simultaneously with the formation of the alumite layer 20 by immersing in an alumite treatment solution containing a lubricant such as a silicon-based lubricant. In addition, it is possible to form the lubricating layer 50 at the time of sealing treatment, for example, by including a lubricant such as a silicone-based lubricant in the treatment liquid to be sealed.

  By providing the lubricating layer 50 on the outermost surface of the aluminum plate member 101 as described above, the sliding of the aluminum plate member 101 is improved, so that it becomes easy to knit smoothly and the surface of the aluminum plate member 101 is also less likely to be damaged.

(Other embodiments)
In the first and second embodiments, the alumite layer 20 is provided by subjecting the material 10x of the aluminum plate 10 or 101 to an alumite treatment, and the dye is allowed to enter the fine pores 22 of the alumite layer 20 to provide the dyed layer 30 Although the pore-sealing treatment for closing the micropores 22 was performed later, the present invention is not limited to this. For example, the material 10x of the aluminum plate members 10 and 101 may be anodized to form an aluminum plate member without sealing treatment. When it is desired to dye a knitted fabric manufactured using this, it can be dyed by a method such as spraying a dye on the surface of the knitted fabric with a spray or soaking in a dyeing solution.

  Furthermore, after using a material 10x of a plate material made of aluminum which is not anodized, the material is knitted by alumite treatment so that the micropores 22 are formed, and the dye 30x is made to enter the micropores 22. After that, the micropores 22 may be sealed by sealing. This method is suitable when it is a relatively simple knit and can be effectively subjected to alumite treatment and dyeing treatment even after knitting.

  In the above embodiment, although the plurality of aluminum plate members 10 are described as having the same width and the same thickness in both the vertical plate members 10a and the horizontal plate members 10b, the plurality of aluminum plate members 10 do not necessarily have the same dimensions. A plurality of aluminum plate members 10 may be combined and knitted.

  Further, the aluminum plate members 10 and 101 may be pure aluminum materials, but aluminum alloys are also included in the present invention. The aluminum alloy is not particularly limited. For example, aluminum alloys such as A6000 series such as A6063 which is a typical extruded alloy, A1000 series, and A5000 series can be applied.
