DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIGS. 1-5 shows the structure of the chair of this invention, and the structure after FIG. 6 shows the structure of a mesh place.
[0018]
As shown in FIGS. 1 to 5, this chair basically includes a seat (1) and a backrest (2).
The seat (1) is composed of a frame (3) made of a hard material having a rectangular frame shape in plan view and a mesh ground (4) stretched.
[0019]
As shown in FIGS. 4 and 5, the mesh base (4) has an inserted piece (5) made of a soft material at its peripheral edge, and the outer surface of the frame (3) from above the frame (3). After the cover is covered, the peripheral edge is folded back inward and the inserted piece (5) is reversed to enter the circumferential holding groove (6) provided on the lower surface of the outer peripheral part of the frame (3). Inserting and tightening the fastening frame (7) from below the frame (3) with fastening means such as a set screw (8), the insertion piece (5) is surely inserted into the holding groove (6). The frame (3) is attached with tension applied.
[0020]
Further, when the fastening frame (7) is fastened to the frame (3), the standing piece (9) provided on the fastening frame (7) is used to fold the inwardly folded portion of the mesh ground (4) into the frame (3 ) Is pushed into a gutter supporting groove (10) provided on the lower surface of the mesh), whereby further tension is applied to the mesh base (4).
[0021]
Similarly to the seat (1), the backrest (2) is composed of a frame (11) made of a hard material having a square frame shape in front view and a mesh ground (12) stretched.
[0022]
Since the mesh ground (12) is stretched to the frame (11) in the same manner as the mesh ground (4) in the seat (1), detailed description thereof is omitted.
[0023]
The mesh ground (4) for the seat (1) is basically composed of a warp yarn group (14) composed of a large number of warp yarns (13) having high tension, as schematically shown in FIG. Then, the elastic yarn group (16) made up of the required number of elastic yarns (15) and the Moor yarn group (18) made up of the required number of molding yarns (17) are alternately entangled so as to be almost orthogonal to the warp yarn group (14). A woven or knitted fabric consisting of weft yarn (weft) group (19).
[0024]
In this example, the elastic yarn group (16) is composed of four elastic yarns (15), and the molding yarn group (18) is composed of two molding yarns (17).
The warp yarn (13) is preferably a 500-denier polyester multifilament.
[0025]
As the elastic yarn (15), it is preferable to use a polyether ester elastic yarn, and its thickness is preferably 100 to 3000 denier and 5 to 50% at a drying shrinkage of 150 ° C.
[0026]
The molding yarn (17) is a polyester-based core yarn entangled with a filament-processed yarn, and preferably has a thickness of 3.5 to 5 in terms of hair count.
[0027]
The mole yarn (17) is preferably made to appear more on the surface side than the warp yarn (13) at a ratio of, for example, 3: 1. It is preferable that the elastic yarn (15) appears on the surface side at a ratio of 1: 1 with respect to the warp yarn (13), that is, the front and back are equal.
[0028]
In FIG. 6, the mesh fabric (4) is shown schematically as a woven fabric structure, but it is more preferable to actually use a knitted fabric structure as will be described later.
[0029]
The mesh fabric (4) thus formed is stretched on the frame (3) of the seat (1) as described above so that the warp yarn (13) faces in the front-rear direction. A feeling can be obtained and the frictional force of the surface can be increased.
[0030]
As schematically shown in FIG. 7, the mesh fabric (12) for the backrest (2) is arranged from the elastic yarn group (16) in the mesh fabric (4) for the seat (1) shown in FIG. The two elastic yarns (15) are deleted, and the rest is the same as the gap.
[0031]
In other words, in the mesh fabric (12), the two elastic yarns (15) in the elastic yarn group (16 ') are separated from each other and two molding yarns arranged close to each other ( 17) It is arranged so as to be close to the molding yarn group (18) consisting of (17).
[0032]
Since the other structure in the mesh ground (12) is the same as that in the mesh ground (4), the same constituent members are designated by the same reference numerals and are not illustrated in detail and will not be described in detail.
[0033]
By stretching this mesh fabric (12) on the frame (11) of the backrest (2) with the warp yarn (13) facing up and down, the stretching force in the left-right direction can be applied to the seat (1). The backrest (2) having slightly the same effect as the seat (1) is obtained.
[0034]
FIG. 8 schematically shows an example when the mesh fabric (4) for the seat (1) is knitted.
In this example, the warp yarn (13) is composed of three types of knitting yarns of chain yarn (20), first mesh knitting yarn (21) and second mesh knitting yarn (22) as shown in FIG. And using a Raschel machine with a warp insertion device to warp the warp knitting structure shown in FIG. 9 to form a mesh turtle shell structure (23) as schematically shown in FIG. The elastic yarn group (16) consisting of four elastic yarns (15) similar to those shown in FIG. 6 is arranged on the straight portion (23a) in the vertical direction so as to be separated from each other, and the mesh turtle shell tissue (23) A mesh fabric (4) having a knitted fabric as shown in FIG. 10 by inserting a molding yarn group (18) composed of two molding yarns (17) and (17) into the inclined portion (23b) of each as a weft yarn. Is forming.
[0035]
As the reinforcing chain yarn (20), for example, a 100 denier polyester filament is preferably used, but an elastic yarn may be used in order to provide stretchability.
The first mesh knitting yarn (21) and the second mesh knitting yarn (22) are preferably made of 500 denier polyester multifilament.
As the molding yarn (17), it is preferable to use the same one as described above.
[0036]
As the mesh ground (12) for the backrest (2), the two elastics in the middle of the elastic yarn group (16) intersecting with the straight portion (23a) of the mesh turtle shell tissue (23) from the configuration shown in FIG. It is better to use the same thread from which the threads (15) and (15) have been deleted.
[0037]
As in the case of the woven fabric, the knitted mesh fabric (4) is also arranged so that the warp yarn (13) faces the front and rear direction of the seat (1), and the knitted mesh fabric (12) is also warp yarn (13 ) Is attached to each frame (3) and (11) as described above so that the back of the backrest (2) faces in the vertical direction.
[0038]
In the backrest (2), the mesh fabric (12) has a smaller number of weft elastic threads (15) than the mesh fabric (4) for the seat (1). This is because it is excellent in design as a mesh that a large load as in (1) is not applied, and that the gap in the mesh is increased to improve the visibility in the front-rear direction.
[0039]
As described above, the mesh fabric (4) (12) is preferably a knitted fabric in which the warp yarn (13) is knitted into a mesh turtle shell structure, but the knitted structure is not limited to this, and other knitted fabrics may be used. Organizations can also be employed.
[0040]
Further, the number of elastic yarns and molding yarns alternately arranged as weft yarns can be freely determined, and various designs can be obtained by changing them.
[0041]
【The invention's effect】
According to the present invention, the following effects can be achieved.
[Claim 1] The mesh ground stretched on the seat or the backrest provides high tension in the longitudinal direction of the seat or in the vertical direction of the backrest, and in the lateral direction perpendicular thereto, As a result, sufficient stretchability can be obtained, so that a good seating feeling can be obtained.
Also, since the morse yarn is entangled with the warp yarn, weft misalignment and fraying are less likely to occur with respect to the warp yarn, and the morse yarn accentuates and prevents the design from becoming monotonous. With this combination, a beautiful mesh structure can be exhibited.
In addition, by exposing the Mole yarn to the surface of the mesh ground, it is possible to obtain a sufficient frictional force to hold the seated person and to make the surface soft, especially when the Mole yarn is seated or backrested. By facing in the left-right direction, it is possible to prevent the seated person's buttocks from sliding in the front-rear direction or the seated person's back in the up-down direction.
[0042]
Claim 2: The width of the portion of the molding yarn appearing on the surface of the mesh base is increased, the portion of the molding yarn is emphasized to exhibit a horizontal stripe, the appearance can be improved, and the frictional force of the mesh base surface can be increased. .
[0043]
Claim 3: The frictional force on the surface of the mesh can be increased and the surface of the seat or the back can be made soft.
[0044]
Claim 4: The void portion of the mesh ground can be formed and can be seen through the mesh ground.
[0045]
Claim 5: The void portion of the mesh ground can be made large.
[0046]
Claim 6: The vertical tension of the mesh can be increased.
[0047]
Claim 7: Sufficient elastic force can be given to the width direction of a mesh ground.
[0048]
Claim 8: Sufficient frictional force and soft feeling can be imparted to the surface of the mesh ground.
[0049]
Claim 9: It is possible to reliably prevent the warp and weft from being displaced and frayed by warping and entanglement of the morse yarn with the slanted portion of the mesh turtle shell structure, and the slanted portion of the mesh turtle shell structure includes the morse yarn. The mesh area can be shaped into a beautiful houndstooth mesh pattern due to the horizontal stripes of the required width and the straight part of the vertical direction of the mesh tortoise shell structure, which balances strength and elasticity. A mesh chair with good design and excellent design can be provided.
[0050]
Claim 10: With such a structure, the seat increases in strength, but the visibility is deteriorated. On the other hand, the backrest decreases in strength, but the visibility is improved.
This means that the seat will receive almost the entire weight of the seated person, so that a high strength is required, and it is rather preferable that the fine structure below the seat cannot be clearly seen from the seating surface. However, because it does not apply as much load as the seat, it may be weaker than the seat in terms of strength. On the other hand, as a feature of the mesh chair, it meets the requirement that good visibility through the backrest is desired. Convenient.
