Abstract

PURPOSE:To firmly and surely bundle material to be bundled, such as electric power cables, by a bundling band pulled out of a reel without occurrence of an excessive part in the band and to ensure an easy insertion of a top part of the band into a body of a bundling tool. CONSTITUTION:In a bundling tool A, the size of a through hole 11 of a body 10 is determined so as to permit a band 100 lapped doubly to be inserted through the through hole. A pair of metallic fastening claws 33, 33 having a resiliency are protrusively provided in the through hole 11 opposedly to each other. A distance T between top parts 34, 34 of the paired fastening claws 33, 33 is determined to permit the onefold band 100 to be loosely fitted and to be slightly smaller than a thickness t2 of the twofold band 100.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding tool, and more particularly to a binding tool constructed separately from a binding band.

[0002]

2. Description of the Related Art FIG. 9 shows a conventional binding tool A. This binding tool A is used together with a flat synthetic resin strip 100, and the synthetic resin body 1 is inserted into the two spaced apart portions of the strip 100 without a large play space. The through holes 2 and 2 are as wide as possible, and a pair of locking claws 3 and 3 that are inclined in a divergent manner are respectively projected into the holes of the through holes 2 and 2.
The locking claws 3, 3 are provided on a metal frame body 5 having a connecting portion 4, and the frame body 5 is the body 1 described above.
Is inserted and held in a mounting hole formed between the two through holes 2, 2.

With reference to FIGS. 9 and 10 to 13, a case will be described in which a conventional binding tool A is used to bind a power cable C mounted on a cable rack B.

As shown in FIG. 10, a strip (splat) 100 pulled out from a reel R is cut by sensationally estimating the length required for bundling, and then cut. 11 is inserted into one of the through holes 2 (for example, the left through hole) 2 as shown by the arrow a and inserted as shown in FIG. In this way, the one end 110 of the strip 100 inserted into the left through hole 2 is locked by the locking claw 3 in the through hole 2 and moves in the inserting direction shown by the arrow a in FIG. Does not move in the pulling direction. Before or after inserting the one end portion 110 of the strip 100 into the through hole 2 on the left side, as shown in FIG. 11, the strip 100 is hung around the cable rack B and the power cable C in a form such as a side rack. The end portion 120 is inserted into the right through hole 2 as shown by the arrow b in FIG. 9 and inserted as shown in FIG. In this way, the other end 120 of the strip 100 inserted into the right through hole 2 is locked by the locking claw 3 in the through hole 2,
Although it moves in the inserting direction shown by the arrow b in FIG. 9, it does not move in the extracting direction. After pulling the other end 120 of the strip 100 to tighten the strip 100, the surplus portion 130 of the strip 100 protruding from the body A is cut off as shown in FIG.

[0005]

As described above,
In the conventional binding tool A, one end portion 110 and the other end portion 120 of the strip 100, which is cut to have a rough length, are separately inserted into the corresponding through holes 2 and 2, and those end portions are cut. The locking claws 3 and 3 are used to sequentially lock 110 and 120 to prevent them from coming off.

Therefore, as shown in FIG. 10, the strip 100 that is pulled out from the reel R and cut may be too long or too short. If it is too long, the excess portion 130 to be cut off after binding is wastefully discarded. If it is too short, the other end 120 cannot be inserted into the through hole 2 of the body 1 to make it impossible to bind it, or even if it is inserted, the portion protruding from the body 1 cannot be secured and the tightening is tight. I will not be able to. And the strip 100
Is cut with a sense of the approximate length, and in many cases, the excess portion 130 is wasted because it is too long.

If the two through holes 2 and 2 of the body 1 are too wide, the retaining action of the locking claws 3 cannot be reliably exerted. It is required that the area be large enough to be inserted without having a large play space. Therefore, there is also a problem that the work of inserting the one end portion 110 and the other end portion 120 of the strip 100 into the through holes 2 and 2 must be a troublesome work.

The present invention has been made in view of the above circumstances, and eliminates the need to cut the strips with an estimate of the length of the strip, thereby eliminating the situation in which the straps cannot be bound together. An object of the present invention is to provide a binding tool that can firmly and surely bind the body without generating an excess portion and that can easily insert the band into the through hole of the body.

[0009]

The tie according to the present invention comprises:
A pair of metal locking claws protruding into the hole of the through hole and having elasticity are provided in a body having a through hole having a size capable of inserting the doubled band for binding. The pair of locking claws are slanted in a constricted manner in the hole, and the mutual intervals of the tip portions of the pair of locking claws that can be locked to the strip are equal to those of the strip. The weight is such that it can be loosely inserted, and it is slightly narrower than the double overlapping thickness.

In the tying member having this structure, a mounting hole is formed in the body so as to cross the through hole, and the locking claw is cut and raised on the U-shaped metal frame body held by being inserted into the mounting hole. And the opening formed by the cut and raised trace of the locking claw in the frame communicates with the through hole and has a size not smaller than the through hole. be able to.

[0011]

In the tying member of the present invention, the tying band pulled out from the reel into the through hole of the body along the direction from the tip of the pair of locking claws to the base end thereof, that is, along the diverging direction of the pair of locking claws. After inserting the tip of the body and inserting it loosely, pull out the band from the through hole and wrap it around a bound object such as an electric cable, and wrap the tip of the band wrapped around the bound object. By inserting the pair of engaging claws into the through holes, through which the strip has already been inserted, in the direction of constriction of the locking claws and inserting the strip, the tip of the strip is slightly projected from the body. The strips are doubly overlapped and inserted into the through holes.

In the above-mentioned state in which the strips are overlapped doubly and are inserted into the through holes, a pair of metal engaging claws are engaged with each of the doubly overlapped strips. Since these locking claws are inclined in a tapered shape, the body does not move in the direction in which the tip of the band is pulled out, but the direction in which the band on the insertion start side of the through hole is pulled and tightened. It is possible to move the body by sliding. Therefore, binding is performed by pulling the insertion start side of the band into the through hole to tighten the band, and then cutting the band and aligning the cut end with the tip.

When performing such a binding operation,
The operation of inserting the front end of the band into the through hole of the body at the initial stage is a work of loosely inserting the front end of the band into the large through hole, and therefore can be performed easily and easily. Also, since the band is cut for the first time when the binding is completed, the length of the band drawn from the reel may become excessive or insufficient, and the excess part may have to be discarded or the binding may become impossible. There is no.

If the body, the locking claw, and the metal frame body having the locking claw are configured as described in claim 2, the body is reinforced by the metal frame body. Not only is it possible to apply a large tightening force, but when molding the body with synthetic resin, it is only necessary to mold the body, which facilitates molding. Also, a metal frame is attached to the body. As a result, the pair of locking claws can be easily assembled to the body.

1 is an exploded perspective view of a binding tool A according to an embodiment of the present invention, and FIG. 2 is a sectional view of the binding tool A according to the embodiment. Since the body 10 of the binding tool A is made of a synthetic resin molded body made of nylon or acetal resin,
It is tough and has excellent weather resistance. The body 10 is formed in a trapezoidal shape, and has a rectangular through hole 11 extending from the front surface to the back surface thereof, and a mounting hole 12 extending across the left and right side surfaces and crossing the through hole 11. is doing. As can be seen in FIG. 2, the through hole 11 has an area large enough to allow the binding band 100, which is doubly overlapped, to be inserted without having a large play space. In addition, the inclined side surfaces 13 of the body 10 have concave and convex surfaces 14 and 14.
Is provided, and the uneven surfaces 14 and 14 are provided at the time of binding work.
If the hand is gripped by the hand, it is made difficult for the hand to slip due to the anti-slip action of the uneven surfaces 14 and 14 and the inclination of the side surfaces 13 and 13. In addition, the back surface of the body 10 is a recessed surface 15 so that the conformability with a body to be bound to be described later can be improved.

A metal frame 30 is inserted and held in the mounting hole 12 of the body 10. The frame body 30 of this embodiment is made of a metal, such as stainless steel, which has a very low risk of rusting and can maintain the required strength for a long period of time. The frame body 30 includes a rectangular substrate portion 31 and a pair of side plate portions 3 that are erected from both ends of the substrate portion 31.
2 and 32 are formed in a U shape. And
By cutting and raising the substrate portion 31, a pair of locking claws 33, 33 having elasticity are formed to face each other. The pair of locking claws 33, 33 have a symmetrical shape and are inclined in a tapered shape, and as shown in an enlarged view in FIG. Equipped with the teeth of the bite. Then, as can be seen in FIG. 2, the pair of locking claws 3
The mutual interval T between the tip portions 34, 34 of 3, 33 is slightly narrower than the double overlapping thickness t2 of the binding band 100, and the single (single) band 100 is used. The thickness is smaller than twice the thickness t1 but is almost twice as large. The rectangular opening 35 formed by the cut-and-raised traces of the locking claws 33, 33 in the base plate portion 31 is longer in length and width than the length and width of the through hole 11 of the body 10 described above.

The frame 30 is inserted and held in the mounting hole 12 of the body 10 by means such as press fitting. As can be seen in FIG. 2, when the frame body 30 is inserted into the mounting hole 12, the frame body 3
The opening 0 of 0 completely includes the through hole 11 of the body 10. In the binding tool A configured in this way, the pair of locking claws 33, 33 project inwardly and symmetrically into the hole of the through hole 11 of the body 10.

Next, the binding work will be described.

As shown in FIG. 3, the binding tool A is inserted into the front end portion 140 of the binding band 100 made of synthetic resin pulled out from the reel R as shown by an arrow d using the through hole 11 (see FIG. 2). In other words, the tip end portion 140 of the band 100 extends in the direction from the tip end of the pair of locking claws 33, 33 of the binding tool A to the base end thereof, that is, along the diverging direction X of the pair of locking claws 33, 33. It is inserted into the through hole 11. This operation is an operation performed on the through hole 11 which is wide enough to allow the bundling strips 100 that are doubly overlapped to be inserted without having a large play space.
This is an extremely easy work of loosely fitting the 40 into the through hole 11.

After this, the strip 100 is pulled out from the through hole 11 (see FIG. 2) for a long time, and as shown in FIG. 4, it is bound to a bound object, for example, the power cable C shown in the figure and the cable rack B on which it is mounted. It hangs around in the shape of a pillow. The front end portion 140 of the strip 100 wound around the power cable C and the cable rack B is made to face the through hole 11 (see FIG. 2) in which the strip 100 has already been inserted as shown in FIG. To
By inserting the tip end portion 140 of the band 100 into the through hole 11 (see FIG. 2) in the constriction direction Y of the pair of locking claws 33, 33 and inserting the tip end portion 140 of the band 100.
Slightly protrude from the body 10. In this way, the strips are inserted in the through holes 11 (see FIG. 2) so as to be overlapped with each other twice, and the pair of locking claws 33 and 33 are provided on each of the overlapped strips 100. Tip 3
4, 34 are locked separately. Tip 140 of band 100
The length of protrusion of the
The length of the locking claw 33 should be such that the tip 140 does not separate from the locking claw 33 even if the biting position of the locking claw 33 against the locking claw 33 is slightly shifted while it is still biting. It is desirable to put it. In the state in which the tip portions 34, 34 of the pair of locking claws 33, 33 are individually locked to the double overlapping belt bodies 100, respectively, the tip portion 140 of the belt body 100 is pulled out, that is, In the direction Y (see FIG. 5) in which the locking claws 33, 33 are tapered, the binding tool A is used.
Although it does not move, the direction of pulling and tightening the band 100 on the insertion start side into the through hole 11 (see FIG. 2) (see FIG. 6).
The binding A can be slid and moved to the arrow e). Therefore, the uneven surfaces 14, 14 of the body 10
7 with one hand, and the other hand is used to tighten the band 100 by pulling the insertion start side of the band 100 into the through hole 11 (see FIG. 2) as shown in FIG.
Cut the strip 100 and cut the end 150
Are aligned with the above-mentioned tip portion 140 to perform binding.

FIG. 8 shows a pair of locking claws 33 after binding.
33 shows the locked state between 33 and the band 100. As shown in the figure, the edge-shaped tip portions 3 of the pair of locking claws 33, 33.
The strips 4, 34 are bite into each of the overlapped strips 100 to prevent the strips 100 from falling out.

In this embodiment, since the body 10 is made of acetal resin, it has excellent weather resistance, the body 10 maintains high strength for a long time, and the pair of locking claws are less likely to rust. Since it is made of stainless steel, it is unlikely that it will rust over time and its retaining function will be impaired. From the above, according to the binding tool of this embodiment, an action of maintaining stable binding strength for a long period of time is exhibited.

In the present invention, the pair of locking claws 33, 33
May be embedded in the body 10 when the body 10 is molded. In addition to the power cable C and the cable rack B described above, the bundled object includes an electric cable installed indoors and outdoors and other industrial fields such as handling items in the fields of transportation and packaging.

[0024]

When a binding operation is performed using the binding tool of the present invention, it is sufficient to align the tip of the band protruding from the body and cut the band after the binding is completed. It is no longer necessary to cut the tying band by sensuously estimating its length. Therefore, the length of the strip does not become excessive or insufficient, and the surplus portion is forced to be discarded, and the binding is not impossible.
Further, since the work of inserting the tip end portion of the band into the through hole of the body at the initial stage of binding is a work of loosely fitting and inserting into the large through hole, the binding work can be performed easily and easily.

According to the second aspect of the present invention, even if the body is molded of synthetic resin, the body is reinforced by the metal frame body, so that a large tightening force is exerted. Moreover, the body can be easily molded and the locking claws can be easily attached to the body.
