The following describes the embodiment of the invention with reference to the drawings.

Figures 1 to 10 show one embodiment of the present invention. In the figures, reference numeral 1 indicates an object to be held. Reference numeral 2 indicates a fastener that surrounds and holds the object 1.

The fastener 2 comprises a band-shaped portion 3 that is flexible at least in a portion of its length (over the entire length in the illustrated embodiment) and surrounds the object to be held 1, and a fastening portion 4 provided on the base end 3a side of the band-shaped portion 3. The fastening portion 4 has an insertion passage 4a through which the band-shaped portion 3 is inserted from its tip 3b, and an engaging portion 4b that engages with the inserted band-shaped portion 3 and restricts movement of the band-shaped portion 3 in the direction opposite to the insertion direction. Thus, the band-shaped portion 3 has multiple engaged portions 3c that engage with the engaging portions 4b, arranged in a line in the longitudinal direction of the band-shaped portion 3.

Here, the belt-like portion 3 is curved and folded back at the middle, with both ends facing each other with a gap between them. The belt-like portion 3 is then formed with an indicator 3d that indicates the folding position for folding the belt-like portion 3 so that the tip 3b of the belt-like portion 3 faces the insertion path 4a and inserting the tip 3b of the belt-like portion 3 into the insertion path 4a. In other words, the relative positions of the tip 3b, the insertion path 4a, and the indicator 3d are determined so that the tip 3b of the belt-like portion 3 faces the insertion path 4a by folding the belt-like portion 3 at the indicator 3d position.

In detail, the insertion path 4a is located farther away (farther away) from the curved portion 3e of the band-shaped portion 3 than the tip 3b of the band-shaped portion 3. The display portion 3d is formed between the curved portion 3e and the base end 3a of the band-shaped portion 3. The display portion 3d is provided so that when the band-shaped portion 3 is bent at the position of the display portion 3d and the band-shaped portion 3 starts to be inserted from its tip 3b into the insertion path 4a, the angle 3f (see FIG. 9) made by the tip 3b side and the base end 3a side of the band-shaped portion 3 becomes an acute angle.

More specifically, the tip portion 3g of the band-shaped portion 3 is bent and inclined inward (i.e., toward the side where the base end 3a of the band-shaped portion 3 is located). The engaged portion 3c is formed on the inner surface of the band-shaped portion 3, and the engaging portion 4b is formed on the side of the insertion path 4a where the base end 3a of the band-shaped portion 3 is located.

Specifically, the object to be held 1 is made of long material such as wiring or piping, and multiple pieces of these are bundled together by wrapping the fastener 2 around them, or the long material is secured to the fixed part (not shown) by wrapping the fastener 2 around the long material. However, the object to be held 1 is not limited to long materials, and can be anything that can be wrapped around the fastener 2. Note that in Figures 5 to 9, multiple pieces of wiring are simplified and shown as cylinders to represent the object to be held 1.

The fastener 2 is made of synthetic resin and is integrally formed from the synthetic resin. However, the fastener 2 may be made of other materials such as fibers and metals in part or in whole, or may be formed by combining a plurality of members. Here, the band-shaped portion 3 has flexibility throughout, as described above. The band-shaped portion 3 has a wide portion 3h that is wider than adjacent portions in the longitudinal direction of the band-shaped portion 3, and the boundary portion between the adjacent portions and the wide portion 3h becomes the display portion 3d. In the illustrated embodiment, the wide portion 3h is located between the curved portion 3e and the base end 3a of the band-shaped portion 3, closer to the base end 3a, and the display portion 3d is the end of the wide portion 3h on the curved portion 3e side. The engaged portion 3c is provided over most of the longitudinal direction of the band-shaped portion 3. In the illustrated embodiment, the engaged portion 3c is provided except for the tip portion 3g, the wide portion 3h, and the portion between the wide portion 3h and the base end 3a. A reinforcing rib 3i extending in the longitudinal direction of the band-shaped portion 3 is provided in the portion where the engaged portion 3c is provided (more specifically, the portion where the engaged portion 3c is provided and part of the tip portion 3g).

The fastening portion 4 is formed in a substantially rectangular parallelepiped shape. The fastening portion 4 is provided so that one surface 4c is flush with the inner surface of the band-shaped portion 3. The insertion passage 4a is provided so as to penetrate the fastening portion 4 in the plate thickness direction of the base end portion of the band-shaped portion 3, and in this insertion passage 4a, an entrance 4d through which the band-shaped portion 3 is inserted is provided on the one surface 4c side (i.e., the side where the tip 3b of the band-shaped portion 3 is located). The engagement portion 4b is provided within this insertion passage 4a. In the illustrated embodiment, a protrusion 4e having a tip portion on the back side of the entrance 4d of the insertion passage 4a is provided on the side of the insertion passage 4a where the base end 3a of the band-shaped portion 3 is located, and the engagement portion 4b is formed at the tip portion of the protrusion 4e.

Next, the effect of the fastener 2 having the above configuration will be described. The fastener 2 has a belt-shaped portion 3, which surrounds and holds the object to be held 1. The belt-shaped portion 3 is curved and folded back at the middle, and both ends are formed to face each other with a gap between them. The belt-shaped portion 3 is provided with an indicator 3d, and when the belt-shaped portion 3 is folded at the position of the indicator 3d, the tip 3b of the belt-shaped portion 3 faces the insertion path 4a of the fastening portion 4 provided on the base end 3a side of the belt-shaped portion 3, and enters the insertion path 4a as it is. In other words, by folding the belt-shaped portion 3 at the position of the indicator 3d provided on the belt-shaped portion 3, the tip 3b of the belt-shaped portion 3 can be easily aligned and inserted into the insertion path 4a of the fastening portion 4, which is easy to work with. In particular, since it can be operated with one hand, the belt-shaped portion 3 can be deformed into a loop even when the object to be held 1 is held together with another hand.

Here, when the band-shaped portion 3 is folded at the position of the display portion 3d and inserted into the insertion path 4a, it is desirable to be able to insert it as it is until the tip 3b of the band-shaped portion 3 protrudes from the insertion path 4a. In the illustrated embodiment, the tip portion 3g of the band-shaped portion 3 is formed in a tapered shape (a shape that becomes narrower toward the tip 3b), and the tip portion 3g is not provided with an engaged portion 3c, so that the band-shaped portion 3 can be easily inserted until the tip 3b protrudes from the insertion path 4a, and the protruding tip 3b can be pinched and pulled with the fingers.

The fastening portion 4 (more specifically, the insertion path 4a) is provided with an engaging portion 4b, which engages with an engaged portion 3c provided on the belt-shaped portion 3, preventing the belt-shaped portion 3 from slipping out of the insertion path 4a and holding the held object 1.

In addition, since the insertion path 4a (i.e., the fastening portion 4) is located farther away from the curved portion 3e of the belt-shaped portion 3 than the tip 3b of the belt-shaped portion 3, it is easy to grasp the fastening portion 4 and wrap the tip 3b side around the back side of the held object 1 (see Figure 5).

In addition, the tip 3g of the strip 3 is bent and inclined inward. Therefore, when the strip 3 is bent at the position of the display 3d, the tip 3b of the strip 3 can easily enter the insertion path 4a.

When the band-shaped portion 3 is folded at the position of the display portion 3d and the band-shaped portion 3 is inserted from its tip 3b into the insertion path 4a, the angle 3f formed by the tip 3b side and the base end 3a side of the band-shaped portion 3 is an acute angle, and when the band-shaped portion 3 is folded further, the angle 3f changes to a right angle. This allows the band-shaped portion 3 to be smoothly inserted into the insertion path 4a. In addition to the angle 3f being an acute angle, the tip portion of the protrusion 4e and the engagement portion 4b are provided in the insertion path 4a on the side of the base end 3a of the band-shaped portion 3, further back than the entrance 4d, so that the protrusion 4e and the engagement portion 4b are less likely to interfere with the entry of the tip 3b of the band-shaped portion 3 into the insertion path 4a (see FIG. 9).

The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the band portion 3 may be flexible over the entire length, but may have some portions that are not flexible.

The belt-shaped portion 3 does not have a shape that is easily bent at the position of the indicator 3d compared to other portions, but the indicator 3d may have a shape that is easily bent by forming a narrow portion where the width of the belt-shaped portion 3 is narrower than both adjacent sides, or a thin portion where the thickness of the belt-shaped portion 3 is thin, and the position of the indicator 3d may be made easier to recognize by applying a conspicuous color to the indicator 3d. In the fastener 2 shown in Figures 11 and 12, the indicator 3d is formed of a narrow portion 3j and a thin portion 3m formed by a horizontal groove 3k extending in the width direction. The portion with the indicator 3d can pass through the insertion path 4a, and if an engaged portion 3c is provided beyond the portion with the indicator 3d, the belt-shaped portion 3 can be tightened even more tightly.

In addition, the tip portion 3g of the band portion 3 is bent and inclined inward, but it does not have to be bent inward.
