Description

  The present invention relates to a bundling band safety block for bundling cables and releasing the bundling and a bundling band with a safety block.

The binding band is used to bind cables during wiring work in a machine room or cabinet of communication cables. The binding band is a band-shaped band surface with a sawtooth-shaped locking groove and a banding hole formed in one end of the band with a locking claw. , And the band tip is inserted into the through hole, and the locking claw is engaged with the locking groove to bind the band. Once the locking claw is engaged with the locking groove, it can be engaged only in the tightening direction for reducing the diameter of the tightening ring, but it cannot be loosened.
Therefore, once binding is performed with the binding band, the binding cannot be released (see Patent Document 1).

However, if the process of adding or removing installed cables occurs, a process of cutting and re-binding the binding band occurs. Nippers etc. are used to cut the binding band, but at this time, the cutting edge of the nipper is inserted between the cable and the binding band to make a gap, so that the cutting edge of the nipper is difficult to enter. There was a risk of damaging the bundled cables and cutting them incorrectly.

  Therefore, the present invention pays attention to the above-mentioned conventional problems, and provides a safety band for a binding band and a binding band with a safety block that can easily cut the binding band without damaging the cables and without cutting erroneously. Objective.

In order to achieve the above object, a safety band for a binding band according to the present invention has an insertion hole that can be attached to a binding band for binding cables, and binds to the outer surface of the cables in a binding state of the cables. A spacer for forming a space between the band and the spacer , the spacer comprising a pedestal that abuts against the outer surface of the cables, and a projecting piece that is erected from the pedestal and that is provided with the band insertion hole. It is a feature.

Before Symbol protrusion may be provided a pair spaced apart.
The spacer may have a U shape in which a projecting piece is erected from the opposite edge of the rectangular pedestal.
A binding band with a safety block according to the present invention is characterized in that, in a binding band for binding cables, the safety block is inserted into the binding band.

  By inserting the binding band safety block according to the present invention through the binding band, a gap is formed between the upper surface of the base and the binding band. As a result, the bundling band through which the safety block is inserted always has the gap at the time of bundling with the cable, so that a cutting edge such as a nipper can be easily inserted into the gap, and the bundling band can be easily cut, Since the pedestal is present on the lower surface of the cutting edge, it is possible to avoid damaging cables and cutting errors when cutting the binding band.

Hereinafter, the best embodiment of a safety band for a binding band and a binding band with a safety block according to the present invention will be described in detail with reference to the drawings.
FIG. 1 to FIG. 5 show schematic views of a binding band safety block 10 according to the embodiment (FIG. 1, front view, FIG. 2, bottom view, FIG. 3, side view, FIG. 4, plan view, FIG. 5, cross section) Figure).

  The binding band safety block 10 is made of 66 nylon. As can be seen from FIGS. 1 and 3, the pair of spacers 14 having a triangular shape and a rectangular shape when viewed from the side are rectangular block bases. The spacer 14 is connected to the edge of the block pedestal 12 so as to face each other to form a U-shape as a whole, and has a front-rear and left-right symmetric structure.

  Rectangular binding band insertion holes 16 are formed in the upper portions of the spacers 14 (see FIGS. 3, 4, and 5). The binding band insertion hole 16 has such a dimension that a band portion 24 of a binding band 22 described later can be inserted. The direction in which the binding band insertion hole 16 is formed is the same as the direction in which the spacers 14 face each other. The lower surface of the binding band insertion hole 16 is a binding band support portion 18 (see FIGS. 1 and 5), which is higher than the upper surface of the block pedestal 12, and supports a binding band 22 described later from below when binding. Play a role. In this embodiment, the block pedestal 12 and the spacer 14 have a structure in which the inside is hollowed out from both side surfaces while leaving a constant thickness as a whole (see FIGS. 2 and 5).

  On the other hand, a schematic view of a binding band used in this example is shown in FIG. FIG. 7 is a cross-sectional view of a binding band used in this embodiment. The binding band 22 is made of 66 nylon and is composed of a band portion 24 and an engaging portion 34 as shown in FIG. 6, and the other end of the band tip portion 26 is joined to the engaging portion 34. On the band surface of the band portion 24, a large number of sawtooth-shaped locking grooves 28 from the band tip portion 26 to the engaging portion 34 are arranged in a line (see FIG. 7). The locking groove 28 has an inclined surface 30 on the band distal end portion 26 side, and an engaging claw holding portion 32 having a vertical cut surface on the engaging portion 34 side. The band portion 24 can be elastically bent in the band surface direction. The engaging portion 34 includes an engaging arm 36, an engaging arm support frame 38, an engaging arm support portion 40, a locking claw 42, and a binding band insertion hole 44. The engagement arm 36 is supported by the engagement arm support frame 38 and the engagement arm support portion 40 and can be rotated by a certain angle with the engagement arm support portion 40 as an axis, but returns to its original position by a restoring force. Yes. Further, a locking claw 42 is disposed at the tip of the engagement arm 36, and the locking claw 42 is positioned in a direction opposite to the insertion side of the band portion 24 of the binding band insertion hole 44 from the engagement arm support portion 40, The binding band insertion hole 44 is inserted. The binding band insertion hole 44 is formed in a rectangular shape so that the band portion 24 can be inserted and the locking claw 42 and the locking groove 28 of the band portion 24 can interfere with each other. The locking claw holding portion 32 comes into contact with the tip of the locking claw 42 when the binding band 22 is bound. Further, the length of the locking claw holding portion 32 in the depth direction with respect to the band surface is approximately the same as the length in which the tip of the locking claw 42 enters the binding band insertion hole 44.

  With the above configuration, the operation and effect of the binding band safety block and the binding band with safety block according to the present embodiment will be described with reference to FIGS. FIG. 8 is a schematic view when the binding band is inserted through the binding band safety block according to the present invention, and FIG. 9 is a schematic view when the binding band with the safety block according to the present invention is bound to the object to be bound. .

  First, the binding band 22 is inserted into the binding band safety block 10 according to the present embodiment (see FIG. 8). Then, since the height of the binding band support 18 viewed from the block pedestal is higher than the upper surface of the block pedestal 12, a gap 20, which is a separated space, is formed between the binding band 22 and the upper surface of the block pedestal 12. In this state, the binding band 22 is bound to the binding object 46 such that the binding object 46 such as a cable comes to the lower surface of the block pedestal 12 of the binding band safety block 10. In order to perform the binding, the entire band portion 24 is bent, and the binding band 22 is inserted from the band tip portion 26 into the binding band insertion hole 44 to form a ring by the binding band 22. At this time, when the binding band 22 is inserted into the binding band insertion hole 44, the inclined surface 30 of the locking groove 28 and the locking claw 42 come into contact with each other. While the locking claw 42 urges the inclined surface 30 and rotates around the engaging arm support portion 40 according to the height of the inclined surface 30, the locking claw 42 causes the band portion 24 to engage with the engaging portion 34. The locking claw 42 encounters the locking claw holding portion 32 when passing through the apex of the inclined surface 30, and the locking claw 42 is a trough portion of the locking groove 28 by the restoring force of the engagement arm 36. Abut. Since the locking grooves 28 are arranged in a line on the band surface, the above-described process is performed until the objects to be bound 46 are bundled while the ring diameter is reduced each time the locking claws 42 pass through the locking grooves 28. Repeatedly, when the object to be bound 46 is stopped at a predetermined position where it can be bound, the locking claw 42 is locked by contacting the locking claw holding part 32 by the tensile stress caused by the binding and the elastic repulsive force of the band part 24. The claw 42 and the locking groove 28 engage with each other, and the bundling work to the bundled object 46 by the bundling band 22 is completed.

  At this time, the binding band 22 and the binding band support portion 18 come into contact with each other, and the binding band support portion 18 is loaded from the binding band 18 in the direction of the lower surface of the block pedestal 12 and in the direction away from the block pedestal 12. However, the binding band support portion 18 is supported by the block pedestal 12 and the spacer 14, and the binding band safety lock 10 according to the present invention including them is a rigid structure, and is not deformed even with the above-described load. Therefore, the gap 20 remains (see FIG. 9).

  Because of the above-described action, it is not necessary to pry a blade edge such as a nipper between the binding band 22 and the object to be bound 46, and the binding band can be easily cut by inserting the blade edge into the gap 20. be able to. In addition, since the block pedestal 12 is located under the cutting edge, it is possible to prevent the object to be bound 46 such as a cable from being damaged when the binding band 22 is cut, and to avoid erroneous cutting. Further, since the binding band 22 is inserted into the binding band insertion hole 44 of the binding band safety block 10, there is no fear that the binding band 22 is detached from the binding band safety block 10 after binding and the binding is loosened. Furthermore, the bundling according to the present embodiment creates a gap 48 as a new space between the bundling band 22 and the outer surface of the object to be bundled 46 on both sides of the bundling band safety block 10 as well as the gap 20. (Refer to FIG. 9) Even when the installation work of the laying cable occurs after bundling, the cable related to the extension can be inserted into the gap, and can be applied to the suspension of the laying cable. Further, in this embodiment, when the inner band dimension of the binding band insertion hole 44 and the cross-sectional dimension of the band part 24 of the binding band 22 are made substantially the same, the binding band insertion hole 44 is inserted into the band part 24 of the binding band 22. Frictional force is generated. As a result, the binding band safety block 10 does not move freely with respect to the binding band 22, so there is no fear that the binding band safety block 10 will be separated from the binding band 22 during operation.

  In the present embodiment, the spacer 14 has a structure in which the spacer 14 is hollowed out from both sides while keeping a constant thickness for the sake of weight reduction (see FIG. 5), but this is not necessarily performed. Further, the gap 20 is sufficient if it has a width of about several millimeters into which a cutting edge such as a nipper can be inserted. Therefore, the binding band support portion 18 only needs to be several millimeters higher than the upper surface of the block base 12.

  In this embodiment, a U-shaped structure using a pair of spacers is used, but a structure using only one spacer can also be implemented. That is, the safety block has an inverted T-shaped structure in which a spacer is joined to the center of the upper surface of the block base. Then, the binding band 22 is inserted into the binding band insertion hole formed in the upper part of the spacer of the safety block in the same manner as described above, the lower surface of the block base is brought into contact with the object to be bound 46, and the binding band 22 is covered in this state. A bundle 46 is bound. Since a gap is formed on both sides of the spacer after bundling and there is a block base 12 at the lower part of the gap, the object to be bound 46 is held by a cutting edge such as a nipper when cutting the bundling band 22 as in the previous embodiment. It can prevent hurting and accidental cutting.

  In this embodiment, 66 nylon is used as a material. However, the material itself may be any material as long as it becomes a rigid body when used in the safety block according to the present invention, and other materials such as 6 nylon and 46 nylon. Polyethylene, polypropylene, fluororesin, polyacetal, etc. can also be used. Of course, the binding band safety block 10 need not be made of the same material as the binding band 22.

  The present invention can be used for manufacturing a safety band for a binding band and a binding band with a safety block that can easily cut the binding band without damaging cables and without being cut erroneously.
