2. Description of the Related Art Conventionally, a reel having a cylindrical body having flanges at both ends has been known as an instrument used for storing and drawing 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 with a steel bar is formed and the band is attached and fixed to the frame so that it is lightweight and convenient to carry. There is. In addition, a stopper for the bundle of electric wires, which uses a somewhat hard analog instead of the frame, is conceivable.

However, even with this band system, the frame is bulky and it is difficult to work while transporting a plurality of electric wires, and the frame remains after the electric wires have been used and must be 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 hard analog instead of the above frame, if the square ring is specially attached to form a stop, the attachment of the square ring is complicated and the square ring is complicated. The ring was expensive to manufacture, so it was a waste to throw it away.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances of the prior art, and is small in size and light in weight, and works while carrying objects to be fastened such as a bundle of electric wires. It is an object of the present invention to provide a stopper for a portable wire ring bundle or the like that is easy to handle, and that can easily handle the stopper after all the electric wires and the like have been used and that is inexpensive.

[0005]

SUMMARY OF THE INVENTION A stopper for a bundle of electric wires or the like according to the present invention comprises a plurality of flexible band members and the other end of the band member which is wound around an object to be fastened. And a take-out wheel having a plurality of tightening portions formed of two square wheel rings to be stopped, the one square wheel ring is integrally formed with the take-out wheel, and the other square wheel ring is projected from one side surface. It is characterized in that it has a locking portion, and 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 that is slightly hard and formed in a substantially ring shape, or by fixing the band member and locking the band member at its end. Further, if the take-out wheel, the square wheel ring, and the mounting ring are made of the same material at a time, the number of manufacturing steps can be reduced.

[0006]

As described above, according to the present invention, a stopper such as a bundle of electric wire rings is formed by integrally molding one square ring with the take-out ring,
The other square ring has a locking part that protrudes from the surface of one side,
It is composed of a tightening portion formed by providing a long hole in the take-out wheel into which the locking portion is fitted. Therefore, the wire can be easily pulled out from the large-sized take-out wheel without breaking the wire bundle.
Even with a small-diameter wire bundle, by pulling the band material and bringing it into close contact, the square ring and the band material strongly approach and clamp the band material, so that a strong tightening can be maintained. Moreover, since the band runs 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, it is 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 when carrying a plurality of 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 rolled up small, or the strip can be pulled out to change the contact state of the rectangular ring and remove the strip from the strip. It can also be rolled up into a ring and a flexible strip that can be broken down into small pieces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 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 a bundle of electric wires according to the present invention. In the figure, reference numeral 1 is a fastener such as a bundle of electric wire rings, and a mounting ring 2 formed of synthetic resin in a slightly rigid and substantially annular 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 and a rectangular ring 6 provided on the take-out wheel 5. It is composed of a rectangular ring 8 having a locking portion 9 that fits in the elongated hole 7. The mounting ring 2 is made of a synthetic resin in this embodiment in the form of a plate whose center is open, and is provided with grooves 2a at a plurality of central positions so that the band 3 can be mounted. Although this band member 3 is bonded, its shape and mounting method are not particularly limited, and any suitable method such as fitting, tying, sewing, bonding, or tacking may be adopted. The band member 3 is formed of synthetic resin, leather, cloth, or the like in 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 synthetic resin into an annular shape having an appropriate width with the central portion opened, and the electric wire is drawn out from the opening in the central portion. Thus, it is formed larger than the mounting ring 2. The take-out wheel 5 is provided with a plurality of one-sided rectangular ring 6 forming the tightening portion 4, and an elongated hole 7 in the vicinity of 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 elongated hole 9
The square ring 8 is attached to the extraction ring 5 by rotating it by 0 ° so as not to come out straight. The square ring 8 can be formed simultaneously with the attachment 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 constructed as described above, the locking portion 9 of the square ring 8 is fitted into the elongated hole 7 of the take-out ring 5 to attach the square ring 8 to the mounting ring. The electric wire ring bundle 10 is placed on the stretched band member 3 attached to 2, and the take-out ring 5 is placed on the electric wire ring bundle 10, and the band member 3 is placed between the square ring rings 6 and 8 as shown in FIG.
When the leading end 3a of the above is passed through and the 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, 8 addressed to the pair are brought together to form a joint, and the upper annulus 8 moves downward. It retreats with respect to the ring 7 on the side to form a vertically displaced joint, and clamps the fitting portion of the strip 3. In this way, the tightening action is extremely strong and absolutely reliable. This is a result that the ring rings 6 and 8 are angular and have a narrowed space in parallel to the circular shape as compared with the circular shape. On the other hand, if a circular space is used instead, the contact portion with the inner wall becomes smaller, Since the pressure contact becomes very uncertain and uncertain, the joining force of the annulus is naturally weak and the band clamp is apt to become loose. It should be noted that when the electric wire is finished, the tension of the strip is released, the joint ring is opened, and the strip is removed, whereby the strip can be easily separated.

In the above embodiment, an example in which the band member is attached to the mounting ring has been described, but the band members may be bonded to each other without using the mounting ring, or may not be bonded.
Further, although the mounting ring, the take-out wheel, and the square ring are described as being simultaneously molded, they may be molded separately or from different raw materials. Furthermore, although the other square ring is shown as an example in which it is fitted into the long hole and stopped, the method of stopping 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 may be made without departing from the spirit of the present invention.

[0011]

[Effect of the Invention] Since the stopper of the present invention is constituted by the take-out ring having the take-out ring, the band member and the tightening portion, the electric wire can be attached to the large take-out ring without breaking the bundle of electric wires. It can be easily pulled out, and the ring-ring joining force and the tightening force that accompanies it are extremely 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. It's as easy as without the ingredients.
After all the electric wires have been used, they can be divided into a ring and a band, and can be reused because they are easy to handle, or they can be discarded because they are inexpensive.
