Description

The present invention is a main material on the surface of fabrics, knitted fabrics, nonwoven fabrics, paper, and fibers used for decorating indoor spaces such as ceilings, wall surfaces, windows, indoor partition surfaces, and the exterior surfaces of indoor ornaments such as furniture and joinery Used for gripping and tensioning flexible decorative fabrics (hereinafter collectively referred to as “decorative fabrics”) such as artificial leather, synthetic leather with a plastic coating as the main material, and natural leather. Used as a part of a sitting frame of a vehicle seat, an office chair, a chaise longue, a sitting chair, a wheelchair, etc. The present invention relates to a cloth spring seat , a partition, and the like which are arranged and stretched with a decorative ground between the two locking rods.

  As a method of stretching the decoration area on the sitting frame, there is a push groove that pushes the edge of the decoration area on the sitting frame, and the edge that presses and locks the edge of the decoration area into the pushing groove together with a thin press fitting Edge press-fitting method (for example, refer to Patent Document 1), double the seat frame to be locked at its edge, press-fit the edge of the decorative fabric into the push groove of one of the frames, and lock it, A double locking method in which the other frame is overlapped with the frame to be locked and the decoration is sandwiched between the frames (see, for example, Patent Document 2), and the pushing groove of the frame for locking the edge of the decoration And the edge of the decorative area is a cylindrical bag edge having an internal cavity, a wedge is inserted into the cavity of the cylindrical bag edge inserted into the dovetail groove, and the cylinder is inserted in the groove cavity inside the dovetail groove. Dovetail type in which the edge of the bag is inflated with a wedge (for example, see Patent Document 3), The edge of the land and the tubular bag edge, a pipe insertion method to insert a pipe forming part of the sag frame to its interior cavity (e.g., see Patent Document 4) it is known.

Japanese Patent Laid-Open No. 2006-110004, FIG. Japanese Patent Laid-Open No. 2006-110000, FIG. Japanese Patent Laid-Open No. 11-137609 (Japanese Patent No. 3486728), FIG. Japanese Patent Laid-Open No. 2003-189981, FIG.

In the above-mentioned edge press-fitting method (see Patent Document 1), it is necessary to fix the press-fitting rod to the seat frame in order to prevent the press-fitting rod from coming out from the pushing groove. However, since a thick press-fit rod and a bulky seat frame that do not break are required, it is impossible to reduce the weight of the seat by the edge press-fitting method and make it slim.
In the double locking method (see Patent Document 2), two frame members are required to sandwich the edge of the decorative fabric. More difficult than the case of the edge press-fitting method.

  In the dovetail method (see Patent Document 3), a metal pipe is used for the sitting frame, and if the dovetail is attached to it, it becomes easy to bend and becomes unstable in strength, and the decoration is strongly tensioned and tensioned. Especially when bending pipes with dovetails, the dovetails are deformed and blocked, so the dovetails form a sitting frame that folds from the backrest to the waist. I can't do it.

  In the above-described pipe insertion method (see Patent Document 4), the pipe (sitting frame) is wrapped in the cylindrical bag edge to be inserted, so that when the pipe is screwed to the body frame of the sitting tool, only the pipe is used. Screw holes must also be drilled in the decorative ground (tubular bag edge), and the decorative ground can be easily released from the screw holes. I can't get it. In the pipe insertion method, it is difficult to construct a sitting frame that is bent from the backrest portion to the waistrest portion as in the case of the dovetail method.

Therefore, the present invention is able to bend the pipe and continue from the backrest part to the waist-mounted part, tension the ornamental area strongly and firmly, and it is light and easy to handle, the appearance is slim and design-like Another object is to obtain a new cloth spring seat and a partition .

In order to achieve the above object, the following matters were confirmed as a result of observing the bent portions of the hoses and pipes that were cracked and broken due to a large change in cross section when bent.
(1) The circular pipe 50 is deformed in the same way on the outer peripheral surface side and the inner peripheral surface side of the bend curve generated by bending, the width T is widened, the cross section is a flat plate, the flat outer peripheral surface side portion 51 and the flat plate The inner peripheral surface side portion 52 is overlapped to form a flat double sectional structure (FIG. 13-d).
(2) The left and right side end portions 53 and 53 of the flat double sectional structure are formed with a gap 55 larger than the central portion 54 between the left and right side end portions 53 and 53, and the side end 56 is A C-shaped cross section is formed to surround the gap 55, and the side end 56 of the surrounding C-shaped cross section serves as a flange that prevents the gap 55 from being crushed (FIG. 13-d).
(3) The side end 56 of the C-shaped cross section serving as the flange is further deformed into a flat plate, and when the surrounding gap 55 disappears, a crack is generated at the bent portion, and the circular pipe 50 is broken. To do.

Based on the observation results, the following findings were obtained.
(1) If the left and right end portions 63 of the original circular pipe 50 before being bent and deformed into the left and right end portions 53 are connected by a flat neutral member 64, the width S of the circular pipe 50 is obtained. Is difficult to spread even when bent (FIG. 13-c).
(2) If the left and right end portions 63 of the circular pipe 50 are connected by a flat neutral member 64, the inner cavity of the circular pipe 50 is divided into two upper and lower semicircular cavities 65 and is not easily crushed. (FIG. 13-c).
(3) If the left and right end portions 63, 63 of the original circular pipe 50 before being bent and deformed to be deformed are reinforced and thickened, the side end is bent and deformed into a C-shaped cross section. Since 56 becomes more difficult to be deformed into a flat plate, cracks are unlikely to occur at the bent portion and it is difficult to break.
(4) Since the left and right end portions 63 and 63 of the original circular pipe before being bent and deformed to the left and right end portions 53 are portions that are difficult to deform into flat plates, they are adjacent to the left and right end portions 63 and 63. If the dovetail grooves 66 and 66 are provided in the dovetail grooves 66 and 66, the dovetail grooves 66 and 66 are hardly deformed (FIG. 13-c).
(5) If the left and right ends 63 and 63 of the circular pipe are connected by a neutral member 64 (FIG. 13-c) and the left and right ends 63 and 63 are made thick, Since only the arcuate portions 61 and 61 between the thickened left and right end portions 63 and 63 are formed, if the circular pipe 50 is formed into an elliptical pipe and the curvature radius of the arcuate portions 61 and 61 is increased, the arcuate portion 61 is obtained. -Even if 61 deforms into a flat plate, it does not deform as much as the left, and the deformation of the cross section of the entire pipe becomes inconspicuous.

  Based on the above knowledge, the present invention makes the cross section of the pipe used for the locking rod 14 elliptical, and connects the left and right end portions of the major axis XX with the neutral plate 35 (64). The internal cavity 12 is vertically divided into two parts, and the left and right side ends 36 (63) are thickened, and the dovetail groove 11 (13) is provided in the thickened left and right side ends 36 (63) to make it easy to bend the pipe. The width (S) of the arcuate portion 61 of the pipe peripheral surface facing the plate 35 is reduced, and even when the arcuate portion 61 is deformed into a flat plate when the pipe is bent, the arcuate portion 61 is completed so as not to be noticeable.

Therefore, Kakaritome桿14 according to the present invention, two dovetail grooves 11, 11 opened toward the elliptical outer (a) cross section forms an oval shape, the major axis axis X direction of its short diameter shaft Y is disposed only on the major axis axis X-X symmetrically boundary, the cross-section of dovetail 11 including the groove cavity 13 in the inner portion, the upper and lower symmetrical forms the boundary of the major axis shaft X, (b 2) The two cavities 12 partitioned by the neutral plate 35 connecting the left and right dovetail grooves 11 and the dovetail groove 11 between the left and right dovetail grooves 11 and the dovetail groove 11 are symmetrically short with respect to the major axis X. is disposed diameter shaft on Y-Y, the two cross-section of each cavity 12 is a first feature that forms a left-right symmetrical to the boundary of the short-diameter shaft Y.

FIG.

In addition to the above, the cloth spring seat according to the present invention has a point that the intermediate portion 28 of the connecting member 15 has a mountain shape that bulges away from the tensioning surface 29 of the decorative fabric. Also good .

In addition to the above, the cloth spring seat according to the present invention has a point that the connecting members 15 and 15 are joined to the waist portion 25 and the support leg portion 27 with the intermediate portions 28 and 28 facing each other. May be .

Cloth spring seat device according to the present invention, the decorative fabric on one side of the edge 21A is engaged with the outside of the dovetail 11aA of one Kakaritome桿14A in two Kakaritome桿disposed in parallel It can also be said that the edge 21B on the other side of the decorative area is locked to the dovetail groove 11bB on the outer side of the other locking rod 14B in the two locking rods. One side from the outer dovetail groove 11 a to the inner dovetail groove 11 b of each locking rod 14 may have a point where the decorative material 17 is covered.

The cloth spring seat according to the present invention includes : (a) a dovetail groove 11bA inside one locking rod 14A in two locking rods arranged in parallel; A backup ground 30 is stretched between the dovetail groove 11aB inside the other one of the locking rods 14B, and (b) the edge 21 'of the backup ground 30 extends along the edge 21'. (C) The cylindrical bag edge 18 'is inserted into the dovetail groove 11bA (11aB) inside the locking rod, and (d) ) A wedge 20 'is inserted into the cavity 19' of the inserted cylindrical bag edge 18 ', and (e) the cavity 19' is inserted into the dovetail groove 13 'by the inserted wedge 20'. puffy with, and sometimes even as the edge 21 of the backup area 30 'is engaged with the Kakaritome桿14 engaged with the dovetail groove 11.

In the cloth spring seat according to the present invention, in addition to the above , the flexible decorative fabric 17 has a breaking elongation of 60 (%) or more and an elastic recovery rate after 15% elongation of 90 (%) or more. An elastic woven knitted fabric having a certain elastic yarn, and a stress (F) at the time of 10% elongation of the elastic woven knitted fabric (17) in the width direction of the cloth spring seat where the two hooks 14 and 14 face each other (F) ( (Unit: N / 5 cm) may have a point where 50 ≦ F ≦ 600 (N / 5 cm).

The partition according to the present invention, the roll screen, the roman shade, the hanging curtain or the lever tension is characterized by using the above-described locking rod 14.

  In the locking rod 14 according to the present invention, the two dovetail grooves 11a and 11b have the minor axis Y on the major axis XX, which is a neutral surface that does not expand and contract when the locking rod 14 is bent in the length direction. Since they are arranged symmetrically at the border, the cross-sectional shape is not deformed at the bent portion 22, and the groove width G is not narrowed so that it is not difficult to insert the tubular bag edge 18 of the decorative fabric.

Since the dovetail 11 which continues in the length direction is formed in the latching rod 14 according to the present invention, a cylindrical bag edge 18 having a cavity 19 is attached to the end edge 21 to attach the decorative ground 17 to the dovetail. 11, when a wedge rod 20 is inserted into the cavity 19 of the inserted cylindrical bag edge 18 and inflated in the groove cavity 13 of the dovetail, the edge 21 of the decorative fabric 17 is engaged with the dovetail 11, Even if the decoration place 17 is pulled strongly, it does not come off from the locking rod 14.
In addition, the locking rod 14 is light and heat-insulating because it has an internal cavity 12, is hard to condense, has an elliptical cross-sectional shape, and has a rounded outer surface that is soft to the touch and has a decorative texture. It is suitable for indoor decoration members that are easy to touch the skin, such as indoor partitions and furniture used.

The locking rod 14 according to the present invention has an elliptical cross section even if there is a cavity 12 inside, and a neutral plate 35 between the left and right dovetail grooves 11a and 11b located on the major axis XX. Therefore, even if it is bent in the length direction of the locking rod, the width (major diameter W) does not increase, and the left and right side ends 36 of the internal cavities 12 and 12 constitute a flange perpendicular to the major axis X. Therefore, even if the locking rod is bent in the length direction, the radius of curvature of the bent portion 22 is unlikely to be small, and the bent portion 22 is bent smoothly without being angular (FIG. 3).

The outer peripheral surface portion 41 and the inner peripheral surface portion 42 of the locking rod facing the neutral plate 35 with the inner cavity 12 in between are joined to the left and right side ends 36 and 36 that form a flange perpendicular to the long axis X. Even when the outer peripheral surface portion 41 and the inner peripheral surface portion 42 protrude in an arcuate shape when the beam Q is formed and its width Q is 0.4 to 1.2 times the major axis W, The protrusion height P does not increase to the left (FIG. 1).
Therefore, when the locking rod 14 is bent according to the curved surface of the interior decoration, even if the outer peripheral surface portion 41 and the inner peripheral surface portion 42 protruding in an arcuate shape at the bent portion 22 are deformed into a flat plate, Deformation is hardly noticeable (FIGS. 13A and 13B).
On the other hand, even if it is almost inconspicuous, since the outer peripheral surface 41 and the inner peripheral surface 42 can be deformed into a flat plate at the bent portion 22 during bending, it can be bent without difficulty. .

  As described above, according to the present invention, the edge 21 of the decorative material 17 can be securely locked, and the decorative material locking rod 14 that can be easily bent according to the curved surface on which the decorative material 17 is stretched is obtained. .

In the cloth spring seat according to the present invention, the locking rod 14 is a part of the seat frame, and the major axis X is arranged in the width direction of the seat so that the tension of the stretched decorative fabric 17 is increased. Acts parallel to the major axis X. Therefore, the locking bar 14 does not bend due to the tension transmitted from the decorative ground 17, and the decorative ground 17 can be strongly tensioned between the locking bars .

In the present invention, upon the intermediate portion 28 of the connecting member 15 to the chevron shape that bulges in a direction away from the ornamental locations Zhang設面29 also sinks decoration areas 17 receives the body pressure, limb is connected The material 15 does not feel pain.

In the present invention, each of Koshino portion 25 and the support leg portion 27 of the seat member frame, when the coupling member 15, 15 facing each other and an intermediate portion 28, 28 is joined, by receiving the body pressure locking Even if the collar 14 bends, the connecting material 15 of the waist portion 25 and the connecting material 15 of the support leg portion 27 that are facing each other are abutted against each other, so that there is no further bending (FIG. 4), and the material is elastic. Even with the lacking locking rod 14 made of hard plastic or aluminum, the bending that occurs during use can be kept within the elastic limit, and by using hard plastic or aluminum, the locking rod 14 can be reduced in weight and rusted. It is possible to obtain the locking rod 14 that does not generate.

In the present invention, the edge 21A on one side of the decorative fabric is locked to the dovetail groove 11aA on the outer side of one of the two locking rods 14A, and the edge 21B on the other side of the decorative fabric is locked to the other one of the two. Since the outer dovetail groove 11bB of one of the locking rods 14B is locked, one side from the outer dovetail groove 11a of each of the locking rods 14 and 14 to the inner dovetail groove 11b is covered with the decorative ground 17 Therefore, it is not necessary to apply metal plating or coating to the locking rod 14, and the manufacturing cost of the cloth spring seat can be suppressed (FIG. 2).
Since the locking dovetail 14 of the present invention is provided with the dovetail grooves 11 and 11 symmetrically on the left and right sides, the outer dovetail groove 11aA and the other side of the dowel groove 14a and 14 are connected so as to cover one side of the locking rod 14 and 14. When the decorative ground 17 is stretched between the outer dovetail groove 11bB of the anchor rod 14B, a lumbar support or a backup ground can be stretched between the remaining inner dovetail groove 11bA and the inner dovetail groove 11aB. .

And the dovetail groove 11bA inside the one lock rod 14A in the two lock rods and the dovetail groove 11aB inside the other one lock rod 14B in the two lock rods In the case where the backup ground 30 is stretched between, the decorative ground 17 stretched between the outer dovetail groove 11aA of the one side locking rod 14A and the outer dovetail groove 11bB of the other one side locking rod 14B. There is no need to be particularly tense, and the decorative fabric 17 can be made of a fabric or plastic film that is easy to stretch even though it has excellent decorative properties, and the design design of the fabric spring seat is free (see FIG. 2. FIG. 6).
In addition, there is a gap in which a functional filling 37 such as a cushioning material or a heat insulating material can be inserted between the outer surface 17 and the backup place 30, so that the cloth spring seat having excellent functionality can be provided by the filling 37. Can be obtained (FIG. 2).

In the present invention , an elastic woven or knitted fabric having a stress (F) at 10% elongation of 50 ≦ F ≦ 600 (N / 5 cm) is used as the decorative fabric 17, and the acting direction of the stress (F) at 10% elongation is defined as the cloth. upon stretched toward the width direction of the spring seat member is never loose or depression occurs in the Zhang設面29, Zhang設面29 is kept elastically smooth, excellent cushioning A cloth spring seat is obtained.
As such, when using the elastic decorative fabric 17 that elastically expands and contracts in the width direction of the cloth spring seat, the vertebra part that is desired to be strongly tensioned, or the front half part that is biased toward the leg side of the waistrest part is used. The elastic decorative ground is cut so that the width is narrow, and it is stretched between two locking rods that are arranged with a constant width (interval) between the left and right sides. While it is strongly tensioned so that it receives weight and does not sink, it is relatively easy to sink in other parts, and the elastic decoration is deformed according to the undulating shape of the body, and the body pressure applied from the body is elastic It is possible to obtain a body pressure dispersion type cloth spring seat that is evenly distributed throughout.

The elastic woven or knitted fabric can also be used for the lumbar support or the backup place 30.
When used for the lumbar support or the backup ground 30 as such, in particular, a decoration that is stretched between the dovetail groove 11aA on the outer side of the locking rod 14A on one side and the dovetail groove 11bB on the outer side of the locking rod 14B on the other side. When using for the lumbar support which suppresses the bending | flexion of the ground 17, the elastic woven / knitted fabric which is hard to stretch | stretch the stress (F) at the time of 10% elongation of 150 (N / 5cm) or more is used.

An elastic yarn having an elongation at break of 60 (%) or more and an elastic recovery rate after elongation of 15% of 90 (%) or more constituting the elastic woven or knitted fabric has a polyether ester as a core component polymer, Uses heat-sealable core-sheath composite polyether-based ester elastic yarn (fineness: 2080 dtex, Toyobo Co., Ltd., product name: Diaflora) using a heat-sealable polymer having a melting point lower than that of the core component polymer as the sheath component polymer. I can do it.
The elastic woven knitted fabric may be a woven fabric using an elastic yarn as either a warp or a weft, or a knitted fabric (warp knitting / weft knitting) using an elastic yarn as either a knitting yarn or an insertion yarn. They may be woven or doubly knitted, or may be a woolen fabric having surface pile napping.
