Description

[0001]
[Industrial applications]
The present invention relates to a binding device, and more particularly, to a binding device configured separately from a binding band.
[0002]
[Prior art]
FIG. 9 shows a conventional binding device A. The tying member A is used together with a flat synthetic resin band 100, and the band 100 is inserted into two places of the synthetic resin body 1 at an interval without having a large play space. Each of the through holes 2 and 2 has a width as large as possible, and a pair of locking claws 3 and 3 which are inclined to protrude into the respective holes of the through holes 2 and 2 respectively protrude. These locking claws 3 are provided on a metal frame 5 having a connecting portion 4, and the frame 5 is opened between two through holes 2 in the body 1. It is inserted and held in the mounting hole.
[0003]
With reference to FIGS. 9 and 10 to 13, a description will be given of a case where a power cable C mounted on a cable rack B is bound using a conventional binding device A.
[0004]
As shown in FIG. 9, the band (splat) 100 pulled out from the reel R as shown in FIG. 10 is cut by sensuously arranging the approximate length of the length required for bundling. It is inserted into one through hole (for example, the left through hole) 2 as shown by an arrow a and inserted as shown in FIG. Thus, one end 110 of the band 100 inserted into the left through-hole 2 is locked by the locking claw 3 in the through-hole 2 and moves in the insertion direction indicated by the arrow a in FIG. Will not move in the withdrawal direction. Before or after the one end 110 of the band 100 is inserted into the through hole 2 on the left side, the band 100 is wrapped around the cable rack B and the power cable C in a crossover manner as shown in FIG. The end portion 120 is inserted into the through hole 2 on the right side as shown by an arrow b in FIG. 9 and inserted as shown in FIG. In this manner, the other end portion 120 of the band 100 inserted into the right through-hole 2 is locked by the locking claw 3 in the through-hole 2, and in the insertion direction indicated by the arrow b in FIG. It moves but does not move in the withdrawal direction. After the other end 120 of the band 100 is pulled to tighten the band 100, the excess portion 130 of the band 100 protruding from the body A is cut off as shown in FIG.
[0005]
[Problems to be solved by the invention]
As described above, the conventional tying tool A separates the one end 110 and the other end 120 of the band 100 cut with the approximate length into separate through holes 2 and 2 respectively. It is used in such a procedure that the end portions 110 and 120 are inserted and then sequentially locked by the locking claws 3 and 3 to prevent the end portions 110 and 120 from coming off.
[0006]
For this reason, as shown in FIG. 10, the band 100 pulled out from the reel R and cut may be too long or too short. If the band 100 is too long, the surplus portion 130 cut off after bundling is wastefully discarded and too short. In such a case, the other end portion 120 cannot be inserted into the through hole 2 of the body 1 so that bundling becomes impossible. I do. Then, since the belt 100 is cut with a sense of approximate length, it is often too long and the surplus portion 130 is wasted.
[0007]
Also, if the two through holes 2, 2 of the body 1 are too wide, the retaining action of the locking claws 3, 3 will not be reliably exhibited, and the through holes 2, 2 will make the band 100 so large a play space. It is required to have a size that can be inserted without having a space. For this reason, there has been a problem that the operation of inserting the one end 110 or the other end 120 of the band 100 into the through holes 2 has to be a troublesome operation.
[0008]
The present invention has been made in view of the above circumstances, eliminates the need to cut the band with an approximate length and eliminates the situation that binding becomes impossible, An object of the present invention is to provide a binding device that can securely and securely bind without generating any portion, and that can easily insert a band into a through hole of a body.
[0009]
[Means for Solving the Problems]
A binding device according to the present invention includes a pair of elastic metal projections that project into the through-holes and have elasticity in a body having a through-hole large enough to allow a double-stacked binding band to be inserted. Claws are provided in opposition to each other, and the pair of locking claws are tapered and inclined in the hole, and a mutual interval between tip portions of the pair of locking claws that can be locked to the band body. However, when the band is single, the width of the band is such that it can be loosely inserted, and the width is slightly smaller than the double overlapping thickness.
[0010]
In the tying device having this configuration, the body is formed of a synthetic resin molded body, a mounting hole is formed in the body across the through hole, and a locking claw is inserted and held in the mounting hole. The opening formed by the cut and raised trace of the locking claw in the metal frame is connected to the through hole and is not smaller than the through hole. Can be provided.
[0011]
[Action]
In the binding device of the present invention, the distal end of the binding band pulled out from the reel into the through hole of the body along the direction from the distal end of the pair of locking claws to the base end thereof, that is, the direction in which the pair of locking claws extend toward the end. After the part is inserted and loosely inserted, the band is pulled out from the through-hole for a long time and wrapped around a tied body such as a power cable. By inserting the pair of locking claws in the direction of tapering and inserting them into the through hole that has already been inserted, the tip of the band is slightly projected from the body. The band is overlapped doubly and inserted.
[0012]
In the above-described state in which the bands are overlapped doubly and are inserted into the through holes, a pair of metal locking claws is separately locked to each of the overlapped bands. Since these locking claws are tapered and inclined, 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 at the beginning of insertion into the through hole is pulled and tightened It is possible to slide and move the body. Accordingly, the band is tightened by pulling the insertion start side of the band into the through-hole, and thereafter, the band is cut and the cut end is aligned with the above-mentioned tip to perform binding.
[0013]
In performing such a binding operation, the operation of inserting the front end of the band into the through hole of the body at the first stage is a work of loosely inserting the front end of the band into the large through hole. Easy to do. Also, since the band is cut for the first time after the binding is completed, the length of the band pulled out from the reel may be too short or too long, so that the surplus part must be discarded or the binding becomes impossible. There is no.
[0014]
In addition, if the body, the locking claw, and the metal frame having the locking claw are configured as described above , the body is reinforced by the metal frame, so that a large tightening force is applied. In addition to this, when the body is molded with synthetic resin, only the body needs to be molded, which facilitates the molding. In addition, the metal frame is assembled to the body, and the Assembling of the pawl becomes easy.
[0015]
【Example】
FIG. 1 is an exploded perspective view of a binding device A according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the binding device A according to the embodiment. Since the body 10 of the binding device A is made of a synthetic resin molded body made of nylon, acetal resin, or the like, it is tough and has excellent weather resistance. The body 10 is formed in a trapezoidal shape, has a rectangular through hole 11 extending from the front surface to the rear surface, and has a mounting hole 12 formed on both left and right sides and across the through hole 11. are doing. As can be seen from FIG. 2, the through-hole 11 is large enough to allow the double-stacked binding band 100 to be inserted without having a large play space. The inclined side surfaces 13, 13 of the body 10 are provided with uneven surfaces 14, 14, and if the uneven surfaces 14, 14 are grasped by hand during the binding operation, the uneven surfaces 14, 14 can be used. The hand is less likely to slip due to the stopping action and the inclination of the side surfaces 13 and 13. In addition, the rear surface of the body 10 is a recessed surface 15 so that conformability with a body to be bound, which will be described later, is enhanced.
[0016]
A metal frame 30 is inserted and held in the mounting hole 12 of the body 10. The frame 30 of this embodiment is made of a metal, for example, stainless steel, which has a very low possibility of rusting and can maintain the required strength for a long period of time. The frame body 30 is formed in a U-shape by a rectangular substrate portion 31 and a pair of side plate portions 32, 32 raised from both ends of the substrate portion 31. A pair of locking claws 33, 33 having elasticity by cutting and raising the substrate portion 31 are formed to face each other. The pair of locking claws 33, 33 have a symmetrical shape, are tapered and inclined, and as shown in an enlarged view in FIG. Biting teeth are provided. Further, as can be seen in FIG. 2, the mutual interval T between the tips 34, 34 of the pair of locking claws 33, 33 is slightly smaller than the double overlapping thickness t2 of the binding band 100. In addition, compared to the thickness t1 of a single (single) band 100, the width is narrower than twice but nearly double. The length and width of the rectangular opening 35 formed by the cut and raised traces of the locking claws 33 in the substrate portion 31 are longer than the length and width of the through hole 11 of the body 10 described above.
[0017]
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 from FIG. 2, when the frame 30 is inserted into the mounting hole 12, the opening 35 of the frame 30 completely includes the through hole 11 of the body 10. In the binding device A thus configured, the pair of locking claws 33, 33 protrude symmetrically into the through hole 11 of the body 10 in an inclined posture.
[0018]
Next, the binding operation will be described.
[0019]
As shown in FIG. 3, the binding tool A is inserted into the distal end portion 140 of the binding band 100 made of synthetic resin drawn from the reel R as shown by an arrow d using the through hole 11 (see FIG. 2). In other words, the distal end portion 140 of the band body 100 extends in the direction from the distal ends of the pair of locking claws 33, 33 of the tying member A to the base end thereof, that is, along the flared direction X of the pair of locking claws 33, 33. It is inserted into the through hole 11. This work is performed on the through-hole 11 having a size that allows the double-stacked binding band 100 to be inserted without having a large play space. This is a very easy operation of loosely inserting the connector 11 into the connector.
[0020]
Thereafter, the belt 100 is pulled out from the through-hole 11 (see FIG. 2) long, and as shown in FIG. 4, the bundled body, for example, the power cable C in the illustrated example and a cable rack B on which the power cable C is mounted are cross-hung. Around the shape. The front end 140 of the band 100 wound around the power cable C and the cable rack B faces the through hole 11 (see FIG. 2) into which the band 100 has already been inserted as shown in FIG. Then, the tip 140 of the band 100 is inserted into the through hole 11 (see FIG. 2) by inserting the tip 140 into the through-hole 11 (see FIG. 2) in the tapering direction Y of the pair of locking claws 33. It is made to protrude slightly from the body 10. By doing so, the band is overlapped and inserted into the through hole 11 (see FIG. 2), and a pair of locking claws 33, 33 is inserted into each of the double overlapped band 100. The tip portions 34, 34 are individually locked. The protruding length of the front end 140 of the band 100 from the body 10 is, for example, such that the front end 140 is slightly It is sufficient that the length is set so as not to be separated from the device, and it is desired that the length be set in consideration of safety. In a state where the tips 34, 34 of the pair of locking claws 33, 33 are separately locked to the doubly overlapped strips 100, respectively, the direction in which the tip 140 of the strip 100 is pulled out, that is, the pair of Although the tying member A does not move in the tapering direction Y (see FIG. 5) of the locking claws 33, 33, the direction in which the band 100 on the insertion start side into the through hole 11 (see FIG. 2) is pulled and tightened. It is possible to slide and move the binding device A to (arrow e in FIG. 6). Accordingly, the concave and convex surfaces 14, 14 of the body 10 are grasped with one hand, and the other hand is used to pull the insertion start side into the through hole 11 (see FIG. 2) of the band 100 as shown in FIG. The band 100 is tightened, and thereafter, the band 100 is cut as shown in FIG.
[0021]
FIG. 8 illustrates a locked state between the pair of locking claws 33, 33 and the band 100 after the binding. As shown in the figure, the edge-like tips 34, 34 of the pair of locking claws 33, 33 bite into each of the doubly-overlapping strips 100 to prevent falling off.
[0022]
In this embodiment, since the body 10 is formed of acetal resin, the body 10 is excellent in weather resistance, maintains high strength for a long period of time, and has a pair of locking claws made of stainless steel that is less likely to rust. Since it is made, it does not easily occur that it rusts with time and the retaining action is impaired. From these facts, according to the binding device of this embodiment, an effect that stable binding strength is maintained for a long time is exhibited.
[0023]
In the present invention, in addition to the above-described power cable C and cable rack B, the object to be bound includes electric cables installed indoors and outdoors, and articles handled in other industrial fields such as transport and packaging.
[0024]
【The invention's effect】
When the binding operation is performed using the binding device of the present invention, the band may be cut out after the binding is completed by aligning the band with the tip of the band protruding from the body. There is no need to sensibly approximate and cut the length. Therefore, the length of the band does not become too short or too long, so that the surplus portion cannot be discarded or binding becomes impossible. In addition, since the operation of inserting the front end of the band into the through hole of the body at the initial stage of the binding is a work of loosely inserting the large through hole, the binding operation can be performed easily and easily.
[0025]
Since the body be previously molded volume di synthetic resin is reinforced by a metal frame, it becomes possible to exert a large clamping force, also, molding or body, the body It is easy to assemble the locking claw with the hook.
