  First, the present invention will be described with reference to the drawings. FIG. 1 shows the entire typical belt of the present invention. The belt of the present invention can be broadly divided into a belt-like locking portion (A) and an opening (C) that extends from one end of the locking portion (A) and through which the end of the locking portion (A) can pass. It is comprised from the opening part (B) which has. Both the locking part (A) and the opening part (B) are formed of a hook-and-loop fastener, and a hook-like engagement element and a loop-like engagement element are mixed (coexisted) on one side (the same as this). A surface fastener having a hook-like engagement element and a loop-like engagement element mixed on the surface may be referred to as a hook / loop mixed surface fastener). Such a hook-and-loop engaging element and a hook-and-loop engaging element on the surface are sold under the trade name of Free Magic (registered trademark) by Kuraray Fastening Co., Ltd. Such a known hook / loop mixed surface fastener can be used in the present invention.

In the hook-and-loop fastener in which the hook-shaped engagement element and the loop-shaped engagement element are mixed on the same surface, the loop-shaped engagement element is more preferably 0.1 than the height of the hook-shaped engagement element. 1 mm higher, the number of hook-like engagement elements and the number of loop-like engagement elements in the range of 30:70 to 70:30, and the total element density of the loop-like engagement elements and the hook-like engagement elements is 20 It is a hook-and-loop mixed surface fastener that is in a range of ˜150 pieces / cm ² . By being a hook-and-loop mixed surface fastener, the engaging portion (A) turned back through the opening (C) is fixed by the engagement of the engaging elements facing each other before and after the turn-back, and is bound. Fixing, connection fixing, etc. will be completed.

The hook / loop mixed surface fastener is preferably a woven fabric formed of polyester fibers, and particularly has a high core component, preferably a heat-fusible polyester fiber, preferably a ground weft constituting the woven fabric. From a polyester resin having a melting point (for example, polyethylene terephthalate having substantially no copolymer component) and a polyester resin having a sheath component having a low melting point (for example, polyethylene terephthalate copolymerized with 15 to 25 mol% of isophthalic acid) And the warp yarn and the engagement element yarn are made of a polyester resin having a high melting point (for example, polyethylene terephthalate substantially free of a copolymer component), and at the stage of producing the hook-and-loop fastener, Surface fasteners that are made by melting and shrinking the resin component and fusing and fixing the surface fastener constituent yarn are Compared with the hook-and-loop fastener used for the hook-and-loop fastener, the hook-and-loop fastener is flexible because there is no need to apply a backcoat resin, such as polyurethane resin or acrylic resin, to fix the hook-and-loop fastener fibers to the back of the hook-and-loop fastener is there. Further, even if the object to be bound or connected using the band of the present invention is a small-diameter rod-like object, it is suitable for the band of the present invention because it is easy to wind without the backcoat resin.

As shown in FIG. 1, the opening (B) is provided with a folded portion (D), and by folding back the hook-and-loop fastener of the folded portion (D), the opening (B) on the side far from the locking portion (A) is provided. The engaging element existing in the vicinity of the side of the opening (C) can be covered with the folded portion (D). That is, by covering the engaging element existing in the vicinity of the side of the opening (C) on the side farther from the locking part (A) with the folded part (D), the belt is looped to bind the objects to be bound. When the engaging part (A) is inserted into the opening (C), the engaging element present on the surface of the engaging part (A) and the engaging element present on the surface near the opening (C) Can prevent unnecessary engagement. In particular, when the locking part (A) is inserted into the opening (C) or when the inserted locking part (A) is pulled out, the locking of the opening (C) existing on the surface of the opening (B) Since the engaging element existing in the vicinity of the side far from the portion (A) easily causes unnecessary engagement with the engaging element existing on the surface of the locking portion (A), an opening is provided to prevent this. The folded portion (D) folded to form (C) covers the engaging element existing in the vicinity of the side of the opening (C) on the side far from the locking portion (A), and exists on the opposite surface. The covering state is fixed by engaging the engaging elements.

In the belt of the present invention, the length and width (W _A shown in FIG. 2) of the locking portion (A) vary greatly depending on the thickness and number of the objects to be bound, etc. A range of a part (A) length of 5 to 80 cm and a width (W _A ) of 0.6 to 5 cm is employed. Further, the width of the opening (B) (W _B shown in FIG. 2) is preferably 1.5 to 3.0 times the width of the locking portion (A). On the other hand, when it exceeds 3 times, only the width of the surface fastener to be used is increased and there is almost no merit.

FIG. 2 schematically shows the opening (B) of the belt of the present invention, and the opening (B) has a substantially U-shaped cut, leaving a side far from the locking portion (A). (S) is inserted. The portion surrounded by the cut line (S) is lifted and folded at the folding line (E) shown in FIG. 2, and the folding portion (D) is turned on as shown in FIG. It adheres to the surface it has. As a result, as shown in FIG. 1, the engaging element existing in the vicinity of the side of the opening (C) on the side far from the locking portion (A) is covered with the folded portion (D).

As a result, the engaging element of the locking portion (A) turned back at the opening (C) is engaged with the exposed engaging element, and the bundled state and the connected state become stronger, which is preferable. . In FIGS. 2 to 4, the description of the engagement elements existing on the surface fastener surface is omitted.

The cut line (S) is preferably substantially U-shaped as shown in FIG. 2 or a substantially arcuate shape because it has both punchability and penetrability to the opening (C) of the locking portion (A). In this case, the term “substantially” may be a state close to that even if the shape is not perfect. Further, it may be H-shaped as shown in FIG. In the case of the H-shape, the hook-and-loop fastener is folded at both folding lines (E) shown in FIG. 3 to cover only the engaging element near the side of the opening (C) on the side far from the locking portion (A). In addition, the engagement element in the vicinity of the side of the opening (C) on the side close to the locking portion (A) can be covered, which is preferable because unnecessary engagement can be easily prevented at the time of binding / release.

Further, when the opening (B) as shown in FIG. 4 has a structure that can be folded in the middle of its length, the opening (B) is folded in the middle of the opening (B), By engaging the engaging elements on the surface of B), the opening (B) becomes a laminated state of the two surface fasteners, so that the strength of the opening (B), particularly in the vicinity of the opening (C) is improved, It is possible to prevent the hook-and-loop fastener from tearing or spreading the tear from the opening (C). As shown in FIG. 4, when folded in the middle of the opening (B), the folded portion reinforces the opening (B). It is described as a reinforcing part (R). And the part turned back in order to form this reinforcement part (R) is described as the return line (R _E ).

When the opening (B) as shown in FIG. 4 is folded and the opening (B) of the hook-and-loop fastener that has folded the entire opening (B) is covered with the reinforcing portion (R) corresponding to the folded portion. Needs to be provided with an opening (R _C ) corresponding to the opening (C) also in the reinforcing portion (R) of the folded surface fastener. In that case, the opening (R _C ) is wider than the opening (C) before being folded back, and in particular, as shown in FIG. 4, it is a folded surface near the side of the opening (C) on the side farther from the locking portion (A). It is preferable to provide a wide opening (R _C ) so that there are no fastener engaging elements. Further, even if the portion E in FIG. 4 is cut, the opening (R _C ) and the opening (C) substantially overlap each other, and at least the vicinity of the opening (C) on the side far from the locking portion (A) is the opening ( B) The effect of the present invention may be slightly reduced if the surface is folded.

The size of the opening (C) is not particularly limited as long as it can pass the locking portion (A). However, as shown in FIG. 2, the width (W _C ) is the width of the locking portion (A). _A range of 1.05 to 1.5 times (W _A ) is preferable.

FIG. 5 is a perspective view of the case where about 20 rod-like bodies are bundled using the band of the present invention. The band of the present invention is wound around about 20 rod-shaped bodies so that the hook / loop mixed surface is on the front side, and the end of the engaging portion (A) that has been turned around is the opening (C) ), And is folded at the opening (C), and the binding is completed by engaging the engaging elements on the surface before and after the folding. At this time, since the engaging element is covered with the folded portion (D) on the folded side of the opening (C), when the locking portion (A) is passed through the opening (C), the locking portion (A) Thus, unnecessary engagement does not occur when tightening by pulling, and workability is improved, and an appropriate degree of tightening can be easily adjusted, and can be freely selected.
Furthermore, since the opening is reinforced by the folded portion (D), it is possible to prevent the hook-and-loop fastener from tearing or spreading from the opening (C).

Further, as shown in FIG. 6, the band of the present invention is fixed to one of the rod-like bodies (or cord-like objects) to be bound by using the folded portion (D), and the locking portion (A ) Can be wound and bound together. By using such a method, the band can be fixed to the surface of the rod-shaped body even after the binding is released, and the problem of the loss of the band that is likely to occur when the binding is released can be solved. Moreover, the feature point of the band of the present invention, that is, it is possible to prevent unnecessary engagement from occurring at the time of binding, is not impaired. As such a use form, the case where the band of the present invention is used for bundling electric cords can be cited. For example, when using the electric cord of a mobile type personal computer, the band of the present invention is fixed to one place of the electric wire cord as shown in FIG. 6, and when carrying the personal computer, bundle the removed electric wire cord, In the state of being bundled, it is suitable for use in a method of binding with the band of the present invention as shown in FIG.

FIG. 7 shows how to use the band when the sheet is fixed to the frame using the band of the present invention. That is, the band of the present invention is wound around the frame (F), the locking part (A) is passed through the opening (C), and the locking part (A) passed through is further provided in the hole provided in the sheet (T). The sheet (T) can be fixed to the frame (F) by engaging the engaging elements of the engaging portions before and after turning back. Examples of such a sheet include a curing sheet covering a construction site, a projection screen, a sheet serving as a signboard, a tent fixed to a column, and an agricultural sheet.

The belt of the present invention can be easily manufactured by punching the hook-and-loop mixed surface fastener having a width wider than the width of the opening (B) into the belt shape of the present invention. At that time, it is possible to make a cut that allows the opening (C) to be formed, or to make a cut separately from the punching.

Thus, the belt of the present invention can prevent unnecessary engagement elements from being engaged with each other at the time of bundling or coupling, and is excellent in workability. Moreover, tearing of the hook-and-loop fastener from the opening (C) can be prevented.
The belt of the present invention is extremely excellent as a rod-like body, particularly as a binding cord for bundling electric wire cords, or as a connecting band for attaching a sheet or the like to a frame.
