Description

本発明は、詰め物の漏出防止構造を備えた布団、及びマチ布片とサポート布片とを多重縫合する縫製装置に関する。 The present invention relates to a futon having a leakage prevention structure for padding, and a sewing device for multiple stitching a gusset cloth piece and a support cloth piece.

布団には、表側生地と裏側生地とを夫々の周縁部に沿って縫い合わせることにより形成した袋体の内部空間に、羽毛、羊毛、及び綿等の繊維状詰め物を充填したものがある。袋体の内部空間に詰め物を充填した布団には、詰め物の偏りを抑制し、且つ内部空間の高さを確保するため、袋体の内部にマチ布(マチテープ)を縫い付けて複数の空間を区画形成し、夫々の空間に詰め物を充填したものがある。このような布団は、例えば立体キルトや二層式キルトと呼ばれている。
袋体の内部にマチ布を縫い付けた布団では、布団の使用に伴ってマチ布と側生地とを縫い合わせている糸に張力が掛かり、側生地の縫い目穴が拡がってしまうことがある。縫い目穴が拡がってしまうと、内部空間に充填された詰め物が縫い目穴を通じて布団の外部に漏れ出てしまう不都合が生じ得た。
出願人は、拡開された縫い目穴を通じて詰め物が布団の外部に漏れ出てしまう不都合を抑制するため、マチ布の一側端部を二つ折りにし、二つ折り部分を側生地の内面に縫い付けた布団を開発した(特許文献1を参照)。
Some futons are filled with fibrous fillings such as feathers, wool, and cotton in the internal space of the bag formed by sewing the front side fabric and the back side fabric along the peripheral edges of each. A gusset cloth (gusset tape) is sewn inside the bag to create multiple spaces in the futon, which is filled with stuffing in the internal space of the bag, in order to suppress the bias of the stuffing and secure the height of the internal space. Some have been partitioned and each space has been filled with padding. Such futons are called, for example, three-dimensional quilts or two-layer quilts.
In a futon in which a gusset cloth is sewn inside the bag body, tension is applied to the thread that sews the gusset cloth and the side cloth with the use of the futon, and the seam hole of the side cloth may expand. If the seam holes are widened, there may be a problem that the padding filled in the internal space leaks to the outside of the futon through the seam holes.
The applicant folds one end of the gusset cloth in half and sew the folded part to the inner surface of the side fabric in order to prevent the padding from leaking out of the futon through the widened seam holes. A futon was developed (see Patent Document 1).

As a result, tension is applied to the thread 7 with the use of the futon 1, and the seam holes 2b of the side fabric 2 (front side fabric 2A, back side fabric 2B) are shown in FIG. 4 (b) from the state shown in FIG. 4 (a). Even if it is expanded to the state, the seam holes 2b are closed by the support cloth pieces 6 (6A, 6B), so that the inconvenience that the padding 8 filled in the internal space SP leaks to the outside of the bag body 3 can be suppressed.

<第1実施形態に係る布団1の詳細>
図1に示す布団1は平面視で四角形状をしており、例えば横方向(幅方向)の長さが150cm乃至230cm、縦方向の長さが200cm乃至230cmである。
布団1は、表側生地2Aと裏側生地2Bの周縁部2a同士を縫い合わせた袋体3を備えている。表側生地2A、及び裏側生地2Bは、布団1のサイズに縫い代を加えたサイズの四角形状の布地によって作製されており、適度な通気性及び柔軟性を備えた布地[例えば絹、ウール、綿、合成繊維(ポリエステル、ナイロン等)、又はこれらの混合繊維の布地]が用いられている。
表側生地2A、及び裏側生地2Bに適度な通気性及び柔軟性を備えた布地を使用する理由は、布団1の外から外力(例えば、人の体重や積層収納時における他の布団の重量)が加わったときに布団1の破裂を防いだり、寝床内環境(就寝中における布団1の内部温度、及び内部湿度)を最適な範囲(例えば温度:32℃乃至34℃、湿度:45%乃至55%)に維持するためである。
<Details of Futon 1 according to the First Embodiment>
The futon 1 shown in FIG. 1 has a quadrangular shape in a plan view, and for example, the length in the horizontal direction (width direction) is 150 cm to 230 cm, and the length in the vertical direction is 200 cm to 230 cm.
The futon 1 includes a bag body 3 in which the peripheral portions 2a of the front side fabric 2A and the back side fabric 2B are sewn together. The front side fabric 2A and the back side fabric 2B are made of a square cloth having a size obtained by adding a seam allowance to the size of the cloth 1, and have appropriate breathability and flexibility [for example, silk, wool, cotton, etc. Synthetic fibers (polyester, nylon, etc.) or mixed fiber fabrics of these] are used.
The reason for using a fabric having appropriate breathability and flexibility for the front side fabric 2A and the back side fabric 2B is that an external force (for example, the weight of a person or the weight of another futon at the time of laminated storage) is applied from the outside of the futon 1. Prevents the futon 1 from bursting when added, and keeps the environment inside the bed (internal temperature and humidity of the futon 1 while sleeping) in the optimum range (for example, temperature: 32 ° C to 34 ° C, humidity: 45% to 55%). ) To maintain.

表側生地2Aと裏側生地2Bとの間には通気性を備えたマチ布4が縫い付けられており、袋体3の内部には複数の空間SPが区画形成されている。図1の布団1において、マチ布4は、横方向に間隔を空けて2つ、縦方向に間隔を空けて3つ縫い付けられている。図1に示す布団1において、マチ布4の高さは、例えば5cm乃至15cmである。
袋体3の内部は、各マチ布4によって12個の空間SPに区画され、図3に示すように、各空間SPには繊維系の詰め物8が充填される。繊維系の詰め物8としては、例えば、羽毛(ダック、グース、マザーグース)、羊毛、綿毛、人工羽毛、又は合成繊維(ポリエステル等)製の綿を用いることができる。
A gusset cloth 4 having breathability is sewn between the front side cloth 2A and the back side cloth 2B, and a plurality of space SPs are partitioned inside the bag body 3. In the futon 1 of FIG. 1, two gusset cloths 4 are sewn at intervals in the horizontal direction and three at intervals in the vertical direction. In the futon 1 shown in FIG. 1, the height of the gusset cloth 4 is, for example, 5 cm to 15 cm.
The inside of the bag body 3 is divided into 12 space SPs by each gusset cloth 4, and as shown in FIG. 3, each space SP is filled with a fiber-based padding 8. As the fiber-based padding 8, for example, down feathers (duck, goose, mother goose), wool, fluff, artificial feathers, or synthetic fiber (polyester or the like) cotton can be used.

マチ布4は、詰め物8の移動は制限し、且つ通気性を備えた布地によって作製することが望ましい。その理由は、詰め物8の移動を制限することにより、夫々の空間SP同士の間で詰め物8の充填量が偏る不都合を抑制できるためである。また、マチ布4が通気性を有することにより当該マチ布4を通じて空気が流通し、夫々の空間SPにおいて温度や湿度が均されるためである。
本実施形態において、マチ布4は、視認可能な大きさの網目(例えば110メッシュ程度の網目)を有する網目織りの帯状布地によって作製されている。なお、マチ布4は、網目織りの帯状布地以外の布地によって作製してもよい。
It is desirable that the gusset cloth 4 is made of a cloth that restricts the movement of the padding 8 and has breathability. The reason is that by restricting the movement of the filling 8, it is possible to suppress the inconvenience that the filling amount of the filling 8 is biased between the respective space SPs. Further, since the gusset cloth 4 has air permeability, air flows through the gusset cloth 4 and the temperature and humidity are leveled in each space SP.
In the present embodiment, the gusset cloth 4 is made of a mesh-woven strip fabric having a mesh having a visually recognizable size (for example, a mesh of about 110 mesh). The gusset cloth 4 may be made of a cloth other than the mesh-woven band-shaped cloth.

The loop of the needle thread 7U is hooked on the tip (sword tip) 105 of the hook 105 that rotates around the bobbin 104 (state of FIG. 10B). As the hook 105 rotates, the loop of the needle thread 7U becomes larger (state of FIG. 10C), and the bobbin thread 7D is arranged inside the loop of the needle thread 7U (state of FIG. 10D). After that, the loop of the needle thread 7U is disengaged from the sword tip 105, and the needle thread 7U is pulled as the mobile sewing unit 102 runs on its own (state in FIG. 10E). Then, the intersecting portions of the needle thread 7U and the bobbin thread 7D are accommodated inside the overlapped cloth pieces 2, 5 and 6 and are sewn multiple times (state in FIG. 10F).
After that, the operations of FIGS. 10A to 10E are repeated.

図10A乃至図10Fの説明から理解されるように、本実施形態の布団1を製造するにあたり、マチ布片5とサポート布片6と側生地2とを多重縫合しているため、多重縫合箇所について必要な厚さを容易に確保できる。その結果、上糸7Uと下糸7Dの張力調整が容易になり、上糸7Uと下糸7Dの交差部分を多重縫合箇所の厚みの中に容易に収められる。その結果、縫い付け作業の効率化が図れる。 As can be understood from the explanations of FIGS. 10A to 10F, in manufacturing the futon 1 of the present embodiment, the gusset cloth piece 5, the support cloth piece 6, and the side cloth 2 are sewn multiple times. The required thickness can be easily secured. As a result, the tension of the needle thread 7U and the bobbin thread 7D can be easily adjusted, and the intersecting portion of the needle thread 7U and the bobbin thread 7D can be easily accommodated in the thickness of the multiple stitched portion. As a result, the efficiency of sewing work can be improved.
