Description

[Detailed description of the invention] This invention relates to a coupling band, and more specifically,
The present invention relates to a non-returnable coupling band that exhibits the same fastening force as a palm type coupling band by using a simple hooking jig, although it is a split type coupling band that is easy to manufacture.

Split-type binding bands have various advantages such as being easy to manufacture, inexpensive, and can be used over the object to be fastened from the outside, but they tend to lack fastening force and are inferior to palm-to-hand type binding bands. In addition, the detents of both the split type and palm type binding bands cannot be said to be perfect, so although various efforts have been made, they are still far from perfect and various problems remain. There is a double-wound band type coupling band to improve these drawbacks, but this requires a large amount of material cost, the tightening margin is not constant during tightening, and the tightening force tends to be unstable. Although sufficient in terms of detents, there are many drawbacks in other respects.

This invention was made in view of the above points, and its purpose is to have a locking hole at one end,
A tunnel-shaped guide fixing part into which the one end can be inserted and crushed with a hammer etc. on the upper surface of the other end, and a locking fulcrum part provided close to the guide fixing part and inside the guide fixing part. a band-shaped member having;
The band-shaped member is curved into a ring shape so that the guiding and fixing part faces outward, and is wound around a part to be fastened such as a rubber tube, and one end of the band-shaped member is inserted through the guiding and fixing part and pulled out. It has an engaging protrusion in the middle that engages with the locking hole portion provided at one end of the pulled out band-shaped member, a lower end is formed as a fulcrum that abuts the locking fulcrum portion, and the other end uses the lower end as a fulcrum. Another object of the present invention is to provide a coupling band comprising a tightening tool formed on a lever portion that can be rotated in a direction in which the diameter of the band member is reduced.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the front view of the coupling band 10 before use shown in FIG. 1, a locking hole 14 is transparently provided in the center of the left end surface of a flat steel strip member 12 extending horizontally in the left-right direction.
A base 16 is fixed to the upper surface of the strip member 12 near the right end. The base 16 is a short member having the same width as the strip member 12, and its left and right ends are spot welded to the strip member.On the upper surface of the base 16, there is a tunnel-shaped strip member at one location on the left. A guide fixing part 18 having a height that allows the guide fixing part 12 to be inserted is provided, and this guide fixing part 1
A guide fixing part 20, also in the shape of a tunnel, is provided on the right side of the guide member 8 at a height that allows the two strip members 12 to be inserted therethrough. At the center of the upper surface of the guide fixing parts 18 and 20, there is a hole 2 with a burr protruding downward.
2 is installed transparently.

To use the coupling band 10 having the above configuration, after wrapping the left end of the band member 12 around a rubber tube or the like in the counterclockwise rotating direction (that is, so that the guide and fixing parts 18 and 20 face outward), It passes through the right guide fixing part 20 and then the left guide fixing part 18 and extends to the left of the base 16. Next, the strip member 1
2, and insert the locking protrusion 24 of the hooking jig 26, which is a fastening tool, into the locking hole 14 provided therethrough from below. The overall shape of the hooking jig 26 is a vertically long plate-like body 2
A locking protrusion 24 that engages with the locking hole 14 is protruded diagonally upward to the right from near the bottom of the hooking jig 26, and the lower end of the hooking jig 26 touches the left end surface of the base 16, which is the locking fulcrum. The band member 12 is tightened by pressing the lever portion at the tip of the hooking jig 26 and pulling the locking hole portion 14 to the left by lever action. When the hooking jig 26 has completely fallen to the left and is in contact with the band-shaped member 12, as shown in FIG. conduct. Next, remove the hooking jig 26, pull up the left edge of the strip member 12, insert the left edge of the strip member 12 into the right guide fixing part 20 from the left, and then insert the left edge of the strip member 12 into the right guide fixing part 20.
The upper surface of the band member 12 is struck with a hammer to cut off the band member 12 that protrudes significantly from the guide and fixing part 20. Note that the locking fulcrum of the hooking jig 26 may be the left end of the guide fixing portion 18.

In another embodiment, there may be only one guiding and fixing part. Further, the locking hole portion 14 can be replaced by another locking portion, such as a recess cut into the side surface of the band-shaped member, and the hole or burr provided in the guide and fixing portion is not necessarily required. By arranging not only one but several locking holes 14 vertically, it is possible to select the most appropriate locking hole and exert sufficient tightening force.

In this way, the present invention overcomes the drawback of the split type coupling band that the tightening force is low and can exert the same fastening force as the palm type coupling band, which is an advantage of the split type and palm type. We can provide a bonding band that combines these functions.

Further, the locking protrusion of the tightening tool is engaged with the locking hole at one end of the band-shaped member, and the tightening tool is tightened using the principle of leverage, so that it can be firmly tightened. In addition, since only a locking hole is formed at the other end, it does not get in the way when passing through the guide and fixing part. Further, since the guide fixing portion can be crushed to fix the band while the coupling band is in a tightened state, the coupling band can be easily fixed and will not loosen during fixation.

Further, since the fastener is removed after the fastener is tightened, the configuration of the band-like member is simplified, and the fastener can be used many times. For this reason, it has significant effects, such as being different from conventional systems in which the lever portion is fixed integrally.

Although various preferred embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to each of the above-mentioned embodiments, and many modifications may be made without departing from the spirit of the invention. Of course, modifications can be made.
