DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of a band body of the present invention will be specifically described below by reference to the drawings.

In the band body of the invention, as shown in FIGS. 1 to 3 , a multifilament 3 which is synthetic fiber of polyamide, polyester, or the like is used as a warp yarn 2 at opposite side edge portions of the band body 1 . As the warp yarn 2 at a center portion, a wire rod 4 molded by using thermoplastic resin such as polyamide, polyacetal, polypropylene, and polybutyrene terephthalate and having a thickness in a range of 0.5 to 2.0 mm and preferably in a range of 0.8 to 1.5 mm is used. As the wire rod 4 , a hollow pipe wire rod 5 which is liable to be deformed is used, for example. The pipe wire rod 5 is woven by a needle loom by using a weft yarn 7 of double pick made of durable monofilament 6 which is a synthetic fiber of polyamide, polyester, or the like, thereby providing different types of woven fabrics together. FIG. 2 is a schematic diagram wherein the woven fabric is rough and the multifilament 3 has a diameter smaller than that of actual multifilament 3 shown in FIG. 1 .

In the band body 1 , flexible and resilient woven fabrics 10 with a desirable touch and appearance can be formed by the multifilaments 3 woven into the opposite longitudinal edge portions, and a rigid resilient woven fabric 11 is formed of the pipe wire rods 5 woven as the warp yarns 2 into the center portion of the band body 1 . Therefore, the band body 1 has at opposite longitudinal edge portions thereof the resilient woven fabrics 10 which are flexible, have a desirable touch, and are thicker than the rigid resilient woven fabric 11 at the center portion, and has at the center portion of the band body 1 the resilient woven fabric 11 which has a strong resilient force and is rigid.

Furthermore, a relationship between the pipe wire rod 5 used as the warp yarn 2 of the rigid resilient woven fabric 11 at the center portion and the monofilament 6 used as the weft yarn 7 of double pick will be described below. As shown in FIGS. 4 to 6 , in the band body 1 , by tightening the monofilament 6 to strongly fasten the pipe wire rod 5 woven as the warp yarn 2 in the center portion, the pipe wire rod 5 is pressed by the monofilament 6 to easily wind upward and downward as shown in FIG. 5 , thereby forming an uneven face 13 on a surface of the rigid resilient woven fabric 11 , and allowing the band body 1 to be easily held. At the same time, by tightening the monofilament 6 as the weft yarn 7 , upward and downward winding of the flexible resilient woven fabrics 10 at opposite longitudinal edge portions is larger than that of the rigid resilient woven fabric 11 , and thus, the flexible resilient woven fabrics 10 are woven to be thicker than the rigid resilient woven fabric 11 . As a result, the opposite longitudinal edge portions of the band body 1 are thick and have desirable appearance and touch, and the rigid resilient woven fabric 11 formed at the center portion of the band body 1 has a strong resilience.

In an embodiment shown in FIG. 7 , a monofilament 8 molded by using thermoplastic resin is used as the wire rod 4 which is used as the warp yarn 2 of the rigid resilient woven fabric 11 formed at the center portion of the band body 1 , and the multifilament 3 which is synthetic fiber is used as the warp yarn 2 in the opposite longitudinal edge portions similarly to the above embodiment. The band body 1 is completed by forming the flexible resilient woven fabrics 10 at the opposite longitudinal edge portions of the band body 1 and weaving the rigid resilient woven fabric 11 at the center portion of the band body 1 . In this band body 1 , similarly to the above embodiment, the opposite longitudinal edge portions are woven to be thick and have a desirable touch and appearance and the rigid resilient woven fabric 11 at the center portion has a strong resilience.

An embodiment shown in FIG. 8 is suitable for a band body 1 with a large width. By weaving the opposite longitudinal edge portions and the center portion of the band body 1 by using the multifilament 3 which is synthetic fiber as the warp yarn 2 , the flexible resilient woven fabrics 10 are formed. Between adjacent pair of the flexible resilient woven fabrics 10 , the rigid resilient woven fabrics 11 are formed by using the wire rod 4 made of thermoplastic resin as the warp yarn 2 , thereby disposing different types of woven fabrics side by side. As the wire rod 4 used as the warp yarn 2 , the hollow pipe wire rod 5 may be used, and the monofilament 8 also may be used.

Next, a manner wherein the band body 1 is used will be described. As shown in FIGS. 9 to 11 , the band body 1 is used as a pull tab 20 of a slide fastener slider 24 . The pull tab 20 has a rotatable connecting ring 15 at its one end. After putting opposite ends of the double folded band body 1 together and inserting the opposite ends into a connecting end stop 14 which has a vertical sectional shape of an angular U and is made of metal, the connecting end stop 14 is pressed from upside and downside to pierce and fix the band body 1 with a piercing tooth portion 27 projecting from an inside of the connecting end stop 14 .

In the pull tab 20 , a bent end portion of the band body 1 is maintained in a properly curved state due to resilience of the rigid resilient woven fabric 11 , thereby forming a space portion 28 . Therefore, a finger can be easily inserted through the space portion 28 in a pulling operation of the pull tab 20 . Also, because the uneven face 13 is formed on a surface of the band body 1 and the monofilament 6 is easily caught by the finger as shown in FIG. 11 , the band body 1 is easy to hold, thereby suppressing slippage and facilitating the operation.

In a manner of usage as shown in FIGS. 12 and 13 , the band body 1 is used as a strap 21 of a cordless telephone 25 as shown in FIG. 14 , of a camera, a transistor radio, or a folding umbrella. With the opposite ends of the double folded band body 1 being put together, the connecting end stop 14 which has a vertical sectional shape of an angular U of thermoplastic resin is integrally molded to attach the band body 1 to the connecting end stop 14 . At this time, the connecting ring 15 which is formed of a looped string is attached to a tip end of the connecting end stop 14 .

In this strap 21 , the resilient space portion 28 is formed at the bent end portion of the band body 1 by the rigid resilient woven fabric 11 . The shape curved to a proper degree is maintained for a long time, and the strap 21 can be conveniently handled.

A manner of usage shown in FIG. 15 shows a case wherein the band body 1 is used as a securing belt 23 . The securing belt 23 is used as a collar 26 of a pet, a wrist watch strap, or the like, for example. In use, a buckle 17 is attached to end portions of the band body 1 such that the end portions can be engaged with and disengaged from each other. Because the band body 1 in use includes the flexible resilient woven fabrics 10 at opposite longitudinal edge portions, the band body 1 has a desirable touch and is suitable for the collar 26 .

In a manner of usage shown in FIG. 16 , the band body 1 is used as a shoulder strap 22 of a shoulder bag, or the band body 1 in a large size is used as the shoulder strap 22 of a golf bag, and the like. Opposite ends of the band body 1 are respectively fixed to a connecting member 16 . A body of the connecting member 16 has a vertical sectional shape of an angular U, and a swivel hook 18 which can be pivoted vertically and laterally is pivotally supported on a tip end portion of the connecting member 16 . The band body 1 is clamped by and fixed to the connecting member 16 and is used by freely hooking the swivel hook 18 of the connecting member 16 in an article to which the strap is to be attached. In this case, because the band body 1 has thick, flexible, and resilient woven fabrics 10 on the opposite longitudinal edge portions, the band body 1 has a desirable touch and provides an extremely comfortable feeling.

Because the monofilaments 6 molded of thermoplastic resin are used as the wire rods 5 as the warp yarns 2 woven into the center portion of the band body 1 to form the rigid resilient woven fabric 11 , a diameter of the monofilaments 6 can be slightly decreased. Therefore, the band body 1 is suitable for a thin band body and has a proper degree of resilience, and the resilience of the band body 1 can be maintained for a long time.

Because the thickness of each the flexible resilient woven fabric 10 formed at each of the opposite longitudinal edge portions of the band body 1 is larger than the thickness of the rigid resilient woven fabric 11 at the center portion of the band body 1 , the opposite longitudinal edge portions are thicker than the center portion of the band body so that the band body 1 with a comfortable touch can be obtained.

The diameter of the wire rod 5 woven into the center portion as the warp yarn 2 is in a range of 0.5 to 2.0 mm. This diameter is a minimum diameter of the wire rod used for the band body, and thus, a desirable resilience can be applied to the band body.

As the wire rods 5 woven into the center portion as the warp yarns 2 and the monofilament 6 woven into the center portion as the weft yarn 7 are respectively made of colorless transparent or translucent material, the band body 1 which is decoratively excellent and unique can be easily obtained.

As the multifilaments 3 which are the same as the multifilaments used as the warp yarns 2 at the opposite longitudinal edge portions are woven as the warp yarns 2 disposed in the rigid resilient woven fabrics 11 at the center portion so as to form the flexible resilient woven fabrics 10 , the flexible resilient woven fabric 10 similar to the woven fabrics 10 at the opposite longitudinal edge portions is formed at the center portion of the band body 1 . Therefore, the band body 1 is suitable for a large band body, and the band body 1 which has a desirable touch and a large width can be easily obtained.

The pipe wire rods 5 woven into the band body 1 as the warp yarns 2 are pressed by the monofilament 6 woven as the weft yarn 7 so as to form an uneven face 13 on a surface of the rigid resilient woven fabric 11 , so that the band body 1 is easy to hold and is convenient for handling and use.

As fluorescent pigment or luminous pigment is applied to an inside of the pipe wire rod 5 woven into the band body 1 as the warp yarn 2 , a fluorescent or luminous function can be easily applied to the pipe wire rod 5 used in the band body 1 , and the decoratively beautiful band body can be obtained.

As fluorescent pigment or luminous pigment is mixed into the monofilaments 6 woven into the band body 1 as the warp yarn 2 , a fluorescent or luminous function can be easily applied to the monofilaments 6 used in the band body 1 , and the decoratively beautiful band body can be obtained.

The band body 1 can be easily and effectively used as a pull tab 20 of a slide fastener slider, a strap 21 to be held for carrying an article, or a securing belt 23 . As described above, the effects exhibited by the invention are extremely remarkable.
