[0002]

[Prior Art]

 Conventionally, a reel having flanges at both ends of a cylindrical body has been known as an instrument used for storing and drawing out a bundle of electric wire rings. However, this reel type has a large weight and is inconvenient to handle for reuse after all the electric wires have been used up. In order to eliminate this inconvenience of handling, a band type is known in which a frame that holds both sides of the wire bundle is formed with steel bars, and the band is attached and fixed to the frame so that it is lightweight and convenient to carry. ing. It is also conceivable to use a wire harness bundle stopper that uses a somewhat rigid analogue instead of the frame.

However, even with this band type, the frame is bulky and it is difficult to work while transporting a plurality of electric wires, and after the electric wires are used, the frame remains and is discarded. It was expensive and bulky, and its handling was a bit cumbersome. In addition, in the case of a wire ring bundle stopper that uses a somewhat rigid analogue instead of the above frame, if the square ring is specially attached and used as a stop, the attachment of this square ring is complicated and the square ring The ring was expensive to manufacture and was a waste to throw away.

[Problems to be solved by the device]

 The present invention has been made in view of the actual situation of the above-mentioned prior art, and it is easy to work while transporting objects to be fastened such as a plurality of bundles of electric wires in a small size and light weight. An object of the present invention is to provide a stopper for a portable wire bundle or the like, which is easy to handle after using all the electric wires and the like and which is inexpensive.

[0005]

[Means for Solving the Problems]

 The fastener such as a bundle of electric wires of the present invention is composed of a plurality of flexible band members and two rectangular ring rings that wrap and clamp the other end of the band member around the object to be fastened. And a take-out wheel having a plurality of tightening portions formed thereon, the one square ring is integrally formed with the take-out ring, and the other square ring has a locking portion projecting from one side surface, A long hole into which the locking portion is fitted is provided in the take-out wheel to form the tightening portion. A more reliable tightening can be achieved by providing the band member from a synthetic resin on a mounting ring formed in a slightly rigid and substantially ring shape, or by fixing the band member and locking the band member at its end. Also, if the take-out ring, the square ring and the mounting ring are made of the same material at a time, the number of manufacturing steps can be reduced.

[0006]

[Action]

 According to the present invention, as described above, a fastener such as a bundle of electric wires is formed by integrally molding one of the square ring and the take-out ring, and the other square ring has a locking portion protruding from one side surface. However, it is composed of a tightening portion formed by forming a long hole in the take-out wheel into which the engaging portion is fitted. Therefore, it is possible to easily pull out the wire from the large-sized take-out wheel without breaking the bundle of wires, and even with a bundle of small-diameter wires, pull the band material and bring them into close contact with each other. Since the strips come close to each other and are clamped and clamped, it is possible to maintain a firm tightening. Moreover, since the band is well along the outside of the bundle of electric wires, and the mounting ring and the take-out ring are formed in a substantially annular shape, they are not bulky, and the bundle of electric wires bundled with a stopper is as bulky as when the stopper is not used. Since it is heavy, there is no problem in transporting multiple wire bundles for work because it is the same as when there is no stopper. When the wire is finished, the strip is flexible and can be made small, or it can be pulled out to change the contact state of the square ring and remove the strip from the unloading wheel. It can also be rolled into small pieces with a ring and flexible material.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 to 4 are views for explaining an embodiment of a stopper such as an electric wire bundle according to the present invention. In the figure, reference numeral 1 denotes a fastener such as a bundle of electric wires, and a mounting ring 2 made of synthetic resin in a slightly rigid and substantially ring shape, and a plurality of flexible band members 3 mounted on the mounting ring 2. And a take-out wheel 5 formed with a tightening portion 4 for holding the other end of the band member 3, and the tightening portion 4 is provided on the take-out wheel 5 with a square ring 6 provided on the take-out wheel 5. It is composed of a rectangular ring 8 having a locking portion 9 that fits into the long hole 7 provided. The mounting ring 2 is made of a synthetic resin in this embodiment in the form of a plate having an annular shape with an opening in the center, and grooves 2a are provided at a plurality of central positions so that the band 3 can be mounted. Although this band member 3 is adhered, its shape and mounting method are not particularly limited, and any suitable method such as fitting, tying, sewing, adhering, or tacking may be adopted. The strip material 3 is formed of synthetic resin, leather, cloth or the like into an elongated tape shape or a band shape, and has flexibility such that it can be freely bent.

The take-out wheel 5 on which the tightening portion 4 is formed is made of a material having a little flexibility such as a synthetic resin into an annular shape having an appropriate width with an opening in the central portion, and an electric wire is pulled from the opening in the central portion. It is formed to be larger than the mounting ring 2 so as to project. The take-out wheel 5 is provided with a plurality of one square ring 6 forming the tightening portion 4, and a long hole 7 near the ring 6. Further, as shown in FIG. 3, the other rectangular ring 8 is formed of a synthetic resin or the like similarly to the take-out ring, and a locking portion 9 is formed by obliquely projecting from one side of the main body portion 8a. A rod portion 9a is formed at the tip of the locking portion 9 in a direction intersecting the axis, and the rod portion 9a is fitted along the long side of the long hole 7 and rotated by 90 ° to form a square ring 8a. Mount the eject ring 5 so that it does not come out straight. The square ring 8 can be formed simultaneously with the mounting ring 2 and the take-out ring 5. Simultaneous molding in this way has a great effect on cost reduction.

Since the tightening portion 4 of the present invention is configured as described above, the locking portion 9 of the square ring 8 is taken out and fitted into the long hole 7 of the ring 5, and the square ring 8 is attached. The wire loop bundle 10 attached to the wire 2 is placed on the wire loop 10 and the take-out wheel 5 is placed on the wire loop bundle 10, and as shown in FIG. When the leading end 3a is passed and the leading end is pulled and tightened to the outside of the take-out ring 5, the locking portion 9 moves in the long hole 7 and the square ring 8 also moves. When the applied force is stopped, the square annulus 8 moves in the opposite direction, the sides of the square annulus 6 and 8 destined for each pair are brought together in a jointed manner, and the upper annulus 8 moves. It retreats with respect to the lower ring 7 to form a shift shape, which is a vertically joined shape, and clamps the fitting portion of the band member 3. In this way, the tightening action is extremely strong and absolutely reliable. This is the result of the annular rings 6 and 8 being rectangular and having a narrower confined space in parallel to the circular shape. On the other hand, if a circular space is used instead, the contact area with the inner wall becomes smaller. Since the pressure contact becomes very weak and uncertain, the joining force of the annulus is naturally weak and the band clamp is likely to loosen. It can be easily separated from the take-out wheel by loosening the tension of the strip and releasing the joint ring when the electric wire is finished.

In the above embodiment, an example in which the band member is attached to the mounting wheel has been described, but the band members may be bonded to each other without using the mounting wheel, or may not be bonded. Further, although the example in which the mounting ring, the take-out ring and the square ring are simultaneously molded has been described, they may be molded separately or from different materials. Furthermore, although the example in which the other square ring is fitted into the long hole and stopped is shown, the way to stop the other square ring is not limited to this example. You may attach so that it may be covered with a square ring. Further, one end of the strip material may be attached to the attachment ring in a tightenable manner. Other various modifications can be implemented without departing from the spirit of the present invention.

[Effect of the device]

 Since the stopper of the present invention is configured by the take-out ring having the take-out ring, the band member and the tightening portion, the electric wire can be easily pulled out from the large-sized take-out ring without breaking the bundle of electric wires. The ring-ring joining force and the tightening force that accompanies it are very strong, and the tightening of the wire bundle is not loose at all. Moreover, the stopper is not bulky, and the wire bundle bundled with the stopper has the same weight and bulk as when the stopper is not used.Therefore, even when transporting multiple wire bundles for work, stop the stopper. It's as easy as without the ingredients. After all the wires have been used, they can be divided into loops and bands, which makes them easy to handle and can be reused, or they can be discarded because they are low cost.
