Description

  The present invention relates to furniture in which a base part covered with a knit cover is formed of cardboard.

  Reference 1 describes an assembly chair in which a sheet of cardboard paper or the like is used to fold a seat, a backrest, an armrest, a leg, or the like so that the chair can be folded and assembled.

JP 2005-21199 A

  However, although this chair can be formed as a three-dimensional object with a single paperboard, it is formed in a complicated shape by combining a large number of mountain folds and valley folds, so the shape of the assembly member and the manufacturing process become complicated. Moreover, the size of the chair after manufacture is determined, and it does not have a size adjusting function such as reducing the size according to the installation space.

  An object of the present invention is to provide a knitted furniture having a base portion made of cardboard that is easy to manufacture and can be sized.

  The knitted furniture of the present invention comprises a base part in which a strip-shaped cardboard is wound in a roll shape to a desired size, and a bag-like knitted cover part in which a closed surface is formed on one side and an opening part is formed on the other side. The base portion is covered with a cover portion.

  The knit cover portion includes a cylindrical surface in which a bag-like tissue is arranged on the periphery of the opening and a closed surface formed by a plurality of triangles, and a string member that can be tied is inserted into the bag-like tissue. It is characterized by that.

  Furthermore, the cylindrical surface and the closed surface of the knit cover part are non-sewn knits formed by a flat knitting machine.

  According to the present invention, a base can be easily formed by winding a strip of corrugated cardboard in a roll shape, and the knit cover has elasticity so that it can be mounted even if the size of the base changes according to the user's preference. .

  According to the present invention, by providing a bag-like structure at the periphery of the opening of the knit cover portion, the knit cover can be fixed to the base by inserting elastic yarns such as rubber yarn or string members after formation. In addition, by forming a closed surface formed of a plurality of triangles, it is possible to make close contact with the upper surface of the base that is circular.

  According to the present invention, the knit cover portion can be formed without sewing, and the formed stitch has an even stretchability.

It is a whole photograph of the chair which is an example of the present invention. It is a bottom face photograph of the chair which is an example of the present invention. It is a figure of a part of pattern of the knit cover part of the chair which is an Example of this invention.

  FIG. 1 is an overall photograph of a chair 1 as an embodiment of the present invention. FIG. 2 is a photograph of the bottom surface facing the closed surface 3 of FIG. 1 is installed with the closed surface 3 with the top 9 near the center as a seating surface and the bottom surface 7 shown in FIG. 2 on the floor side. A chair 1 composed of a knit cover 2, a base 4 formed by winding a strip of cardboard in a roll shape, and a string 6 inserted and tied into a bag-like tissue 5 at the end of an opening connected to the cylindrical surface 8. Is shown. Knit furniture can be used in a variety of fields, but especially for furniture, such as chairs, tables, and pedestals, you can easily adjust the cylinder diameter to change the size or change the cover. Suitable as a possible product.

  In this embodiment, a chair as a knit furniture will be described as an example. The chair 1 shown in the photograph in FIGS. 1 and 2, after preparing the base 4, separately covers the knit cover part 2 formed without sewing using a flat knitting machine, and the peripheral edge of the opening of the knit cover part 2. A string 6 is inserted into and tied to the bag-like tissue 5 provided in.

  The base 4 is formed by winding a strip-shaped cardboard in a roll shape so as to have a cylinder diameter desired by the user. The cylinder diameter of the base 4 can be easily adjusted according to the number of turns. Also, it is not necessary to use special tools. Here, the type of cardboard is single-sided cardboard. Single-sided cardboard is slightly weaker than double-sided cardboard, but can be easily bent without creases and is very easy to wind. Further, the height of the single-sided cardboard can be adjusted in the height direction, and can be freely changed according to the cylinder diameter of the seating surface. Because it is a cardboard material, it can be easily cut with a cutter.

  In order to increase the cylinder diameter with a single-sided cardboard having a limited length, a cylindrical core may be used at the center of the cylinder diameter. Since it is covered with the knit cover part 2, there is no problem of appearance. The string 6 and the stretchable thread can be inserted into the bag-like tissue 5 located on the bottom surface of the chair 1, and the knit cover portion 2 can be tied and fixed so as not to move. In this embodiment, the string 6 is inserted, but a rubber thread having high stretch strength may be used.

  FIG. 3 is a diagram of a part of the pattern of the knit cover portion 2 of the chair 1 as an embodiment of the present invention. This is a single-sided display. Actually, the same material overlaps the front and rear two layers, and at the time of formation, a cylindrical knitted fabric is formed in which both ends thereof are connected. The knit cover part 2 is knitted in the direction of the arrow shown in the drawing. First, using a flat knitting machine having at least a pair of front and back needle beds, the bag-like tissue 5 provided on the periphery of the opening is knitted to the front and rear needle beds, and then the bag-like tissue 5 is formed both front and rear. Therefore, it becomes a state of 4 layers, and the space which can penetrate the string 6 and the rubber thread can be formed in a cylindrical shape. The number of knitting needles that can be used for knitting of each layer is halved, and the stitches formed with respect to the stitches on the cylindrical surface 8 are increased. Subsequently, a circular knitting is performed using the front and rear needle beds to form the cylindrical surface 8.

  Furthermore, in order to form the closed surface 3, it is knitted toward the top 9. Twelve closing surfaces 3 are collected including triangles not shown in the figure. Triangle tops 9 converge toward the center of the closing surface 3 by providing multiple stitches at a plurality of locations in the direction of the wale and successively reducing the knitting width and regularly setting the position where the reduction is performed. It looks like this. Here, since the number of reductions and the position are the same, each triangle is an isosceles triangle. All the triangles have the same height from the base, and if the ratio of the height to the base is high, the number of triangles may be increased. If the height ratio is low, the number of triangles can be reduced. Both can make the closed surface 3 flat.

  Finally, after the apex 9 of the triangle converges and the knitting width is reduced to about 2 to 10 stitches, the bind off process is completed. The knit cover part 2 is knitted without sewing, and the joining of each triangle is only the formation of double stitches by reduction, so that the stretch of the stitches is not hindered by sewing with a sewing machine or the like. Even if the cylinder diameter of the base 4 is changed, the closing surface 3 is in close contact with the upper surface of the base 4 having a circular shape, and the string member inserted through the bag-like tissue 5 located on the bottom surface 7 of the cylindrical surface 8 connected thereto is tied up. Thus, the deviation can be eliminated. In this embodiment, cotton yarn is used to form the knit cover portion 2, but if stretchable yarn is used, the fit can be further enhanced.

  In the present embodiment, the knitted structure of the knit cover part 2 is formed of a structure in which the front and back stitches alternate in the wale direction and the course direction. In this structure, the unevenness can be expressed well, but of course, a tense structure, a rib structure, a mesh structure, or a knitted jacquard structure or an intarsia structure may be used. Since it is formed using a flat knitting machine, such as reversible formation, pockets for storing objects, and combinations with different gauges and different materials, it can be used for various types of knitwear and accessories.

  The chair 1 formed in the present embodiment may be made of a recyclable material such as cardboard or thread, and if cardboard is seen, it may be disposed as recycled paper. Further, if the cover part is damaged, it becomes an ecological product that can be used by replacing only the cover part. The material of the base 4 is cardboard, so there is a limit in strength compared to metal and reinforced plastic, but since it is wound in multiple layers, the strength is increased compared to those with space made of the same material . In addition, it is stable when sitting because of its moderate weight.
