Description

  The present invention relates to a body belt, a backpack, a rucksack, a shoulder bag, a golf bag, and other shoulder belts that are used to hang a garment around the waist of a garment. Pants hanging belts, nursing belts and rescue belts that lift and support the body, and body belts that contact the body such as seat belts used to fix the body to the seat This is related to the belt.)

  When wearing any body belt such as a body belt or shoulder belt, the body belt compresses the skin and gives it a tight feeling, causing it to feel stuffy and painful, sometimes inducing injuries such as skin touch To do.

In order to relieve the compression load transmitted from the body belt to the skin, it is well known that the body belt is folded back twice via a metal fitting, and the contact area between the body belt and the skin is doubled to distribute the pressure load. (For example, see Patent Document 1).
In addition, it is also well known that a patch that also serves as a non-slip body is attached to a part of the body belt as a means for dispersing the compression load (see, for example, Patent Document 2).

  In order to make the garment belt lightweight and slim, it seems that a cloth garment belt that is strong and difficult to stretch like a polyester fiber cloth and can be freely deformed along the undulations of the skin (skeleton) is suitable. The accessories do not seem suitable.

  The cloth garment belt 20 ″ is highly flexible, deforms along the undulation of the skin, and increases the contact area with the skin, so that the compression load is dispersed and more breathable than the leather belt. There are also advantages such as richness, crampedness and sultry.

  However, when the cloth belt 20 ″ is worn for a long time, it gradually plastically deforms along the undulations of the skin 10, the width is reduced, the compressive load tends to concentrate, the shape collapses and becomes undesirably ( Fig. 4-a) has the disadvantage that it lacks durability.

  In terms of durability, it is better to wear a fitting that does not lose its shape, but the fitting 20 'that does not lose its shape is not easily deformed according to the undulation of the skin (Fig. 4-b), and the compression load (X Y) concentrates on the skin 10 locally, leaving a worn mark on the skin 10 that induces skin touch.

  Therefore, the present invention distributes the compressive load to the skin 10 and does not cause stuffiness or pain even if it is worn for a long time, does not leave a wear mark on the skin, and does not induce injury such as skin touch. The purpose is to obtain a pressure-distribution-type garment belt that is lightweight, slim and gentle to the skin without being deformed when worn for a long time.

  The body belt according to the present invention has (a) an elongation at break of 60% or more, an elongation of 15%, an elastic recovery after elongation of 90% or more, a single fiber fineness of 200 dtex or more, and a stress at 10% elongation of 10%. Woven and knitted using a monofilament elastic yarn of 0.1 cN / dtex to 0.8 cN / dtex, (b) Stress (F) at 10% elongation in the length direction is 50 (N / 5 cm) or more, A first feature is that the elastic woven / knitted fabric 21 is 600 (N / 5 cm) or less.

  The second feature of the accessory belt according to the present invention is that, in addition to the first feature, (b) the stress (F) at 10% elongation in the length direction is 50 (N / 5 cm) or more, The elastic woven / knitted fabric 21 having a length of 600 (N / 5 cm) or less forms a part in the length direction, and (c) the total width of the portion constituting the elastic woven / knitted fabric 21 is 20 mm or more.

The third feature of the accessory belt according to the present invention is that, in addition to the second feature, (d) an intermediate portion in the length direction of the accessory belt 20 is constituted by an elastic woven / knitted fabric 21;
(E) The both end portions before and after the intermediate portion are constituted by a proof band 22 having a stress (F) at the time of 10% elongation in the length direction of 600 (N / 5 cm) or more.

  In addition to any of the first, second, and third features, the fourth feature of the accessory belt according to the present invention is that (f) a plurality of intermediate portions in the length direction of the accessory belt 20 are provided. The partial pressure elastic woven and knitted fabrics 21a and 21b are divided.

  In addition to any of the first, second, third, and fourth features, the fifth feature of the accessory belt according to the present invention is (g) gripping metal fittings 23 and 24 at both ends of the accessory belt 20. (H) One gripping fitting 23 is provided with an insertion port 25 through which the body belt 20 is inserted, and (i) the body belt 20 passes through the insertion port 25 and the other side is inserted. Folded back to the gripping metal 24, (j) The body belt 20 is doubled between the gripping metal 23 and the gripping metal 24 at both ends.

  The sixth feature of the accessory belt according to the present invention is that, in addition to any of the first, second, third, fourth and fifth features, (k) the elastic woven knitted fabric 21 is a warp knitted fabric. In that point.

  The seventh feature of the garment belt according to the present invention is that, in addition to the sixth feature, (l) an elastic woven or knitted fabric 21 is composed of a front fabric 12 comprising a front yarn 11 and a back fabric 14 comprising a back yarn 13. Are connected by a connecting yarn 15 and are knitted and knitted integrally, and (m) a monofilament elastic yarn is knitted into one of the front cloth 12 and the back cloth 14.

The eighth feature of the accessory belt according to the present invention is that, in addition to the seventh feature, (n) one front yarn 11a adjacent to the left and right in the course direction C is integrated with the adjacent left front yarn 11b. The chain stitch 18a and the chain stitch 18b integrated with the adjacent right surface yarn 11c are alternately formed every several courses. (O) The chain stitch 18a and the chain stitch 18b are wale. A chain stitch row 19 following the zigzag is formed in the direction W, and (p) an opening 17 having an opening area of 1 mm ² or more surrounded by the chain stitch row 19 following the zigzag is formed in the top cloth 12 (q ) A monofilament elastic yarn is knitted into the backing cloth 14.

A woven or knitted fabric using elastic yarns such as polyurethane whose stress at 10% elongation is less than 0.1 cN / dtex stretches greatly even when a slight load is applied like a sock's mouth. The length is not kept constant, the dimensions are unstable, and it cannot be used for an accessory belt.
If an inelastic yarn is used in combination to suppress the stretchability of the elastic yarn, the entire body belt is deformed due to the permanent distortion of the inelastic yarn, resulting in a loss of shape.

In that respect, in the present invention, the stress at the time of 10% elongation of the elastic yarn is 0.1 cN / dtex or more, the fineness thereof is thick and at least 200 dtex, and the stress at the time of 10% elongation of the woven / knitted fabric is 50 (N / Since it is 5 cm) or more, it does not greatly expand and contract even when subjected to a compression load.
And since the stress at the time of 10% expansion | extension of the woven / knitted fabric is 600 N / 5 cm or less, it deform | transforms according to the undulation of the skin body 10, a contact area with skin body spreads, and a compressive load is disperse | distributed uniformly and is transmitted to the skin body 10. .

If a part and an intermediate part in the length direction of the garment belt 20 are constituted by the elastic woven / knitted fabric 21 (FIG. 1-a), the entire garment belt greatly expands and contracts even when elastic yarns that are easily stretchable are used. , There will be no problems that would interfere with wearing.
In this way, if a part and an intermediate part of the length of the garment belt 20 are constituted by the elastic woven / knitted fabric 21, the elastic woven / knitted fabric 21 can relieve the elongation stress acting on the load bearing belt 22. Further, the deformation of the load bearing belt 22 can be suppressed.

  When the intermediate portion is constituted by a plurality of divided partial pressure elastic woven fabrics 21a and 21b (FIG. 1B), the contact portions of the partial pressure elastic woven fabrics 21a and 21b according to the undulations of the skin. It is possible to change the pressure load widely and evenly, and even when the stress at the time of 10% elongation of the elastic woven fabrics 21a and 21b exceeds 500 (N / 5 cm), it is difficult to give a rough feeling.

  When the accessory belt 20 is folded back to the insertion opening 25 of one of the gripping fittings 23 and 24 attached to both ends of the accessory belt 20 through the attachment belt 20 (FIG. 1-c), The length from the gripping bracket 23 to the gripping bracket 24 of the folded two-piece body belt can be freely changed according to the undulation of the skin to be crimped (FIG. 2), and these partial pressure elastic knitting The compression load acting on the skin from the fabrics 21a and 21b can be made uniform.

  When the elastic knitted fabric is a warp knitted fabric, the elastic woven fabric is easy to expand and contract even from its stitch structure, and even when the single fiber fineness of the elastic yarn is 1000 dtex or more, the garment belt 20 can be easily adapted to the skin. I can do it.

  The elastic knitted and knitted fabric 21 is integrally woven and knitted by connecting the front cloth 12 as the front thread 11 and the back cloth 14 as the back thread 13 with the connecting thread 15, and either the front cloth 12 or the back cloth 14 is connected. When the monofilament elastic yarn is knitted, the breathability of the elastic woven knitted fabric 21 is increased and the feeling of stuffiness is not given, and the compressive load is dispersed from the front cloth 12 and the back cloth 14 to act evenly on the skin and cushioning properties. Therefore, it is possible to obtain an accessory belt 20 that is difficult to be worn and has a gentle skin.

In particular, in the course direction C, one chain yarn 11a adjacent to the left and right is integrated with the adjacent left surface yarn 11b, and the chain stitch 18b integrated with the adjacent right surface yarn 11c is several courses. The chain stitches 18a and the chain stitches 18b are alternately and repeatedly formed to form a chain stitch row 19 following the zigzag in the wale direction W, and the opening area surrounded by the chain stitch row 19 following the zigzag is 1 mm. ^The elastic woven or knitted fabric 21 (FIG. 3) in which ^two or more openings 17 are formed in the front cloth 12 has high breathability and is integrally formed with the back cloth 14 that is elastically deformed. Even if the front cloth 12 is easily deformed, the accessory belt 20 is not easily deformed.

  Thus, according to the present invention, the compressive load is dispersed and transmitted to the skin 10, and even if it is worn for a long time, it does not feel stuffy or painful, there is no trace of wear on the skin, and it causes injuries such as skin touch. A pressure-distribution-type garment belt that is lightweight, slim, and gentle on the skin can be obtained without inducing, causing long-lasting wear and no loss of shape.

The “woven / knitted fabric” in the present invention includes both woven fabrics and knitted fabrics.
In the woven fabric, the elastic yarn is applied so that the elastic yarn continues in the length direction of the garment belt.
The elastic yarn can be used as a covered yarn in which it is covered with a non-elastic yarn, for example, a polyester fiber multifilament yarn wrapped around the elastic yarn.
The warp knitted fabric may be used with its wale direction W oriented in the length direction of the accessory belt.
Since the warp knitted fabric has stretchability due to its stitch structure, even if an elastic yarn is used together with a non-elastic yarn such as a polyester fiber multifilament yarn, the stretchability of the elastic yarn is not particularly impaired thereby.

  In particular, no particular tension (external force) acts during wearing in the width direction of the accessory belt, which is the course direction C of the warp knitted fabric. Accordingly, a yarn knitted so as to continue longer in the course direction C than the wale direction W, for example, an insertion yarn knitted to connect adjacent chain stitch rows in the course direction C without forming a knit loop. Inelastic yarns can be used.

However, this does not mean that the elastic yarn should not be used for the insertion yarn, but only for the knitting yarn forming the knit loop.
This is because, when an elastic yarn is used as an insertion yarn, it is zigzag-continuous in the wale direction W, so that the elastic elasticity changes in the wale direction W like an extension coil spring (helical spring).

FIG. 3 shows a specific example of an elastic woven knitted fabric 21 knitted by a double raschel warp knitting machine.
The elastic knitted knitted fabric 21 is formed by integrally knitting a front cloth 12 constituting the front yarn 11 and a back cloth 14 constituting the back yarn 13 by connecting yarns 15 that do not constitute the front cloth 12 and the back cloth 14. A gap layer 16 having a layer thickness of 0.3 mm or more is formed between the front cloth 12 and the back cloth 14 and separated by the connecting thread 15.
In the course direction C, one of the front yarns 11a adjacent to the left and right is composed of a chain stitch 18a integrated with the adjacent left front yarn 11b and a chain stitch 18b integrated with the adjacent right front yarn 11c by several courses. It is formed alternately every other time.
The chain stitch 18a and the chain stitch 18b form a chain stitch row 19 following the zigzag in the wale direction W, and the front cloth 12 has an opening area of 1 mm ² or more surrounded by the chain stitch row 19 following the zigzag. An opening 17 is formed.
The back yarn 13 includes a ground knitting yarn 13a that forms a chain stitch row 19 following the wale direction W, and a chain stitch row 19 and a chain stitch row 19 that are adjacent to each other in the course direction C without forming a stitch (knit loop). It is comprised by the insertion thread 13b which connects between.
The lining fabric 14 includes a ground knitting yarn 13a that forms a chain stitch row 19 following the wale direction W, and a chain stitch row 19 and a chain stitch row 19 that are adjacent to each other in the course direction C without forming a stitch (knit loop). They are knitted into a plain woven fabric by inserting yarns 13b that connect them.

The elastic yarn is used for the ground knitting yarn 13a and the insertion yarn 13b.
The elastic yarn has a single fiber fineness of 200 dtex or more, preferably 500 dtex or more, and a stress at 10% elongation of preferably 0.15 cN / dtex to 0.6 cN / dtex. ) Depending on the tension that a normal synthetic fiber having a single fiber fineness of 1.1 to 10.0 dtex, which constitutes a normal synthetic fiber filament yarn such as nylon, polypropylene fiber or polyester fiber, is subjected to the weaving process. A thick monofilament elastic yarn exhibiting an elongation rate that allows expansion and contraction is used so that the knitting is not hindered by expanding and contracting during the weaving and knitting process.
As such an elastic yarn, a heat-fusible core-sheath composite polyether ester elasticity in which a polyether ester is a core component polymer and a heat-fusible polymer having a melting point lower than that of the core component polymer is a sheath component polymer. It is desirable to use yarn (for example, Toyobo Co., Ltd. product name: Diaflora).

  The stress (F) at the time of 10% elongation of the elastic woven / knitted fabric 21 is set to 70 to 400 (N / 5 cm) depending on the type and fineness of the inelastic yarn using both the kind and fineness of the elastic yarn and the woven / knitted density. It is desirable to do.

For the load-bearing belt 22, a leather belt or a cloth belt used in a conventional body belt can be applied.
1 and 2 show an accessory belt 20 used for the bag 27.
As the gripping brackets 22 and 23, those conventionally used for bags can be used.
The bag 27 and the holding fittings 22 and 23 are connected by a load-bearing band 26.
