Description

  INDUSTRIAL APPLICABILITY The present invention is applied to a load support member for a chair such as a backrest of a chair or a tension member stretched on a seat, or a blindfold member for a panel, and used to form a part of various furniture. The present invention relates to a furniture fabric.

For example, in a chair, when sitting, the surface where the seated person's body contacts, that is, the backrest surface that supports the body and the seating surface of the seat body are knitted or woven into a mesh shape to form an elastic structure. There is one configured by stretching a tension member made of a fabric (see, for example, Patent Documents 1 and 2).
Such a tension material supports the upper part of the back as compared with the lower part supporting the lower part of the back, for example, the amount of backward deflection that is elastically deformed by the load of the body when the seated person leans on the backrest. When the upper side is enlarged, it is possible to obtain an appropriate breathability as well as a comfortable sitting comfort.

  However, in the backrest of the chair described in the above-mentioned Patent Document 1, a mesh-like tension material composed of a uniform density is stretched on the backrest frame that forms a frame shape. If the lower part has an appropriate amount of bending, the upper side will be greatly bent backwards. Conversely, if the upper part of the tensioner is set to have an appropriate amount of bending, the lower side will be bent too much. Cannot be obtained.

  Further, in the backrest described in Patent Document 2, a belt-like mesh portion (low elastic portion) facing in the left-right direction is formed on the entire surface of the fabric constituting the upholstery material (backrest sheet body). Since the mesh parts are alternately arranged in the vertical direction and knitted in a plurality of stages, the amount of flexure of the entire tension material is substantially uniform, and the rear side of the upper side compared to the lower side It is not possible to improve the sitting comfort by increasing the amount of bending.

Further, the upholstery material is formed by composing long yarns in a mesh shape, and its own elastic deformation force is uniform in any part of the entire fabric surface.
For this reason, when this upholstery is applied to the backrest surface of the backrest of a chair or the seating surface of a seat, for example, the support strength against the load of the seated person's back, buttocks, and parts where the feet touch each other is different. With a tension material having a uniform deformation force, a preferred seating feeling corresponding to each part of the body cannot be obtained.

  In order to solve such problems, as a chair previously filed by the present applicant and already published, a backrest upholstery material is given a strong elastic resistance to the waist of a seated person who requires a strong support force. There is one configured to be able to do this (Patent Document 3).

  The upholstery material stretched on the backrest of the chair described in Patent Document 3 is completely divided into a mesh-like ground structure in an elastic fabric and a strip that is denser than the ground structure, and has a strong bearing force. Is configured to correspond to the portion corresponding to the waist portion of the seated person, and the ground tissue to correspond to the other portions.

JP 2003-135200 A JP 2006-094995 A JP 2009-112360 A

  However, in the upholstery material described in Patent Document 3, since the mesh-like ground structure and the strip portion denser than the ground structure are adjacent to each other, the seated person corresponds to the vicinity of the waist. Therefore, the difference in elastic support force at the boundary between the ground tissue and the strip is extremely large, and a comfortable seating feeling cannot be obtained.

  In addition, when the elastic fabric is applied as a blindfold member for a panel, there is a large difference in permeability between the ground structure and the strip portion. There is a problem that the blindfold effect cannot be exhibited properly.

  The present invention has been made in view of the above problems, and when applied as a load support member for a chair, while being able to obtain a comfortable sitting comfort, when applied as a blindfold member for a panel, An object of the present invention is to provide a furniture fabric that can appropriately exhibit a blindfold effect.

According to the present invention, the above problem is solved as follows.
(1) For furniture made of a fabric of a ground structure composed of a plurality of warps or wefts each consisting of at least one of single yarn or thick twisted yarn and composed in a lattice shape with warps and wefts respectively configured In the fabric, a plurality of weft strip portions wider than the wefts are arranged in the fabric, spaced apart from one end to the other end in the warp direction of the fabric, and these warp directions are mutually The interval between the weft strips adjacent to each other is gradually decreased from one end in the warp direction to the other end, and then gradually increased from the smallest portion to the other end. To form.

(2) In the above paragraph (1), by increasing the width of the weft strips by increasing the number of thick wefts constituting the weft strips in the arrangement interval between the weft strips By gradually reducing the width from one end to the other end in the warp direction of the fabric, and then reducing the number of the thick wefts from the smallest portion to narrow the width of the weft strip , Gradually increase.

(3) In the above item (1), the arrangement interval between the weft strips is reduced from one end to the other end in the warp direction of the fabric by reducing the number of meshes between the adjacent weft strips. The number of eyes is gradually reduced toward the other end, and then the number of eyes is increased from the smallest portion so as to gradually increase toward the other end side.

(4) In any one of the above items (1) to (3), the pattern of the array pattern formed by the plurality of weft strips is continuously repeated at least once in the warp direction of the fabric.

According to the invention described in claim 1, the weft strip portion having a width wider than the weft is applied from one end to the other end side in the warp direction of the fabric on the ground structure formed in a lattice shape by the warps and the weft. A plurality of spaced apart arrangements of weft bands adjacent to each other in the warp direction are gradually reduced from one end to the other end side in the warp direction of the fabric, and then the minimum. Gradually increased from the part to the other end side, in other words, gradually decreased from one end or the other end in the warp direction to the inward direction, for example, as a load support member for a chair, When the vicinity of the part where the arrangement interval between the weft strips is small is used as the back of the hip or the buttocks of the seat, the difference in elastic support force between the part of the ground tissue and the part of the weft strip Get a comfortable sitting without feeling uncomfortable It can be.
Moreover, when applied as a blindfold member for a panel, the portion of the weft strip is provided over a wide area, so that the blindfold effect can be appropriately exhibited.

  According to the invention described in claim 2, the arrangement interval between the weft strips is increased by increasing the number of thick wefts constituting the weft strips and by increasing the width of the weft strips. By gradually decreasing the length from one end of the warp direction to the other end side, then reducing the number of thick wefts from the smallest part and narrowing the width of the weft strip, the other end The width of the weft strip is changed by increasing or decreasing the number of repetitions of the same operation in the process of manufacturing the fabric. It is possible to easily form an array pattern by the weft strips on the surface of the ground texture.

  According to the invention described in claim 3, the arrangement interval between the weft strips is reduced from one end to the other end in the warp direction of the fabric by reducing the number of meshes of the texture between adjacent weft strips. By gradually decreasing the size as it goes and increasing the number of eyes from the smallest part, the size gradually increases toward the other end, so in the fabric manufacturing process, An array pattern with a plurality of weft strips can be easily formed on the surface of the ground structure only by reducing or increasing the number of eyes in the longitudinal direction.

  According to the invention described in claim 4, by forming the pattern of the array pattern formed by a plurality of weft strips repeatedly in the warp direction of the fabric at least once, it can be applied to a large piece of furniture. However, it can be easily applied.

FIG. 7 is a partially enlarged front view showing a mesh composed of warps and wefts constituting the texture of the fabric, and FIG. 7 shows warps and wefts constituting the texture in the corner frame B part of FIG. It is a schematic diagram which partially enlarges and shows a composition state with a strip.

  As shown in FIG. 4, the upholstery material 16 is composed of a ground structure 17 a in which an elastic fabric 17 is composed in a lattice shape with warps 18 and wefts 19.

The warps 18 and the wefts 19 are formed in a lattice shape with substantially the same width, thereby forming a ground structure 17a having a uniform eye.
As shown in FIG. 6, when the warps 18 and the wefts 19 are formed in a lattice pattern, the ground structure 17 a has, for example, a 2 mm-wide warp 18 and a 2 mm-wide weft 19 of 2 mm each. When the composition is formed in a lattice form with a space, a square eye with a length of 2 mm and a latitude is uniformly formed in the center of the lattice.

As shown in FIGS. 1 and 4, the weft 19 extending in the left-right direction has a weft strip 20 wider than the weft 19 in the warp direction, that is, in the vertical direction of the backrest 12. The backrest 12 is formed so as to extend in the left-right direction.
The weft strip portion 20 is configured more densely than the ground structure 17a.

The weft band ridges 20 is moved away from one another in the warp direction of the fabric are arrayed, the arrangement interval d _1, d ₂ ···· d _n weft band ridges 20 adjacent to these warp directions once gradually smaller as the direction from the front end of the upper end from the lower or seat support 7 of the backrest 12 to the position corresponding to the waist of the seated person at a substantially central portion of the rear, made gradually larger from the site became its minimum d _n as Do arrangement interval _{d n, d n + 1 ····} , in other words, it has the form as the arrangement interval of the weft band ridges 20 together toward the upper and lower ends of the backrest 12 inwardly is small, Further, as shown in FIG. 5, by projecting these weft strips 20 onto the surface of the ground structure 17a, an array formed by a plurality of weft strips 20 on the surface of the ground structure 17a. A pattern (hereinafter referred to as a horizontal pattern) is formed.

The horizontal pattern can be repeatedly formed at least once in the warp direction of the fabric according to the size of the backrest 16 of the chair to be applied.
The arrangement of the plurality of weft strip portions 20 can stably support the back of the seated person.

In the case of forming the weft band portion 20, in the composition of the weft 19 in the ground structure 17a to be described later, the combination of the fine warp 21 and the thick weft 23, the thick weft 23 of the ground structure 17a is used. It is carried out by composing into a knot weave structure that can protrude like a wrinkle from the surface.
As a result, the weft strip portion 20 can be protruded with a step on the surface of the ground texture 17a as a strip-shaped step portion.

That is, in order to compose the fabric texture 17a, as shown in FIG. 7, the warp 18 is composed of a plurality of single yarns 21, for example, four fine warp yarns 21a to 21d and a plurality of thick twisted yarns. 22, for example, four thick warps 22a to 22d, and two fine warps 21a to 21d are arranged on both sides of each of these thick warps 22a to 22d.
On the other hand, the weft 19 is composed of a plurality of thick twisted yarns 23, for example, three thick wefts 23a to 23c.
In addition, a plurality of single yarns 24, for example, three transparent fine weft yarns 24a to 24c are used as reinforcing yarns in the lattice gap that becomes the eye holes between the wefts 19 adjacent to each other in the warp direction. It is arranged.

Next, the composition state of the ground tissue 17a in the fabric will be described.
For the fine warp yarns 21a arranged outside one of the four fine warp yarns 21a to 21d constituting the warp 18, the three fine weft yarns 24a to 24c are three thick weft yarns. It is organized in a plain weave state over 3 through 23a-23c.
For the fine warp yarns 21d arranged on the other outer side, three fine weft yarns 24a to 24c and three thick weft yarns 23a to 23c are organized in a plain weave state.

For the four thick warps 22a to 22d constituting the warp 18, the three fine wefts 24a to 24c and the three thick wefts 23a to 23c are alternately organized in a plain weave state. The two outer thick warps 22a and 22d in the four thick warps 22a to 22d are respectively compared to the inner two thin warps 21b and 21d in the four thin warps 21a to 21d. Organized in a woven state.
As a result, the fabric texture 17a is composed in a lattice pattern with the warps 18 and the wefts 19, and the warp 18 after the composition is displaced in the weft direction, or the wefts 19 are displaced in the warp direction. It is structured so that the lattice form can be securely held.

In order to form the wefts 19 constituting the fabric texture 17a of the upholstery material 16 on the weft bands 20 that can partially protrude from the surface of the texture 17a, for example, in the wefts 19 shown in FIG. Two thick wefts 23 are overlapped on both sides in the warp direction, and these thick wefts 23 are supplemented with fine wefts 24 as reinforcing yarns as needed during the weft 19 weaving process. However, it is performed by composing with a thick weave 23 together with a thick weft 23 constituting the weft 19.
Also, equivalent sequences distance d _1, d ₂ ···· d _n between the weft band ridges 20 adjacent to the warp direction from each other, the seated person's waist from the upper end of the backrest 12 at the substantially central portion of the lower position to gradually smaller as toward to the width s _1, s ₂ ···· s _n of the weft Obijo unit 20, the partially increase the number of Futoshite weft 23 at the same time, Nukitaijo 20 This is done by gradually decreasing the number of eyes in the warp direction between them.
Furthermore, the arrangement interval between the Nukitaijo portion 20 with minimal d _n, and the arrangement interval of the weft band ridges 20 between the width of Nukitai strip portion 20 from the widest s _n sites d _n, d _{n + 1} · In order to gradually increase the diameter, the number of thick wefts 23 is partially reduced, and at the same time, the number of meshes in the longitudinal direction of the ground structure 17a between the weft strips 20 is gradually increased.
In this case, for example, in an upper part of the backrest 12, the arrangement intervals d ₁ and d ₂ between the weft strips 20 are wide and the widths s ₁ and s _{2 of} the weft strips 20 are narrow and almost equal. In addition, by reducing only the number of meshes in the longitudinal direction of the ground structure 17a between the weft strips 20 adjacent to each other in the warp direction, it is also possible to partially reduce the array interval between the weft strips 20 partly. is there.

In the above-described embodiment, the tension material stretched on the backrest of the chair has been described as an example. However, the present invention is also applicable to a large-sized panel such as a tension material stretched on a seat body or a large panel. It is also possible to do.
When the seat body, the arrangement interval d _1, d ₂ ···· d _n of each weft Obijo 20 together to form the widthwise corrugation pattern, from the front end of the seat body of the seated person at a substantially central portion of the rear arranged once to become gradually smaller as toward the portion corresponding to the buttocks, subsequent arrangement interval d _n, arranged so that progressively increasing the d n _{+ 1} · · · ·, in other words, from the front and rear ends of the seat support By arranging so that the arrangement interval between the weft strips 20 becomes smaller toward the inward corresponding to the seated person's buttocks in the substantially central part, the seated person's buttocks can be stably supported.
In the case of a large furniture blindfold member, it can be easily applied by forming a horizontal pattern at least several times continuously in the warp direction of the fabric according to the size, and the blindfold effect can be achieved. It can be demonstrated appropriately.
