Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a binding band that can be used for binding electric wires and other wires, strips, etc., for binding the opening of bags, and for other purposes.

[Prior Art] Conventionally, various bands used for bundling electric wires and other wires, strips, etc. are made by winding a strip around the wire or strip and locking the strip by locking teeth in a through hole in a locking head. It is integrally molded to lock the insert part of. These are, for example, Utility Model Publication No. 4947, Utility Model Publication No. 51-
Publication No. 6373, Special Publication No. 10074, Special Publication No. 1983
The one disclosed in Publication No. -48424 is known.

[Problems that the invention attempts to solve] However, with these conventional cable ties,
Since the through hole of the insert part of the locking head is opened in a direction perpendicular to the longitudinal direction of the strip,
As shown in FIG. 22, when the insert portion is passed through the locking head, the insert portion has a shape substantially perpendicular to the longitudinal direction of the strip. Therefore, a dead space was created in the interior A near the penetrating portion, and the objects to be bound could not be sufficiently tightened. Further, when the band is tightened strongly, there are problems in that the object to be tied is easily damaged due to the group of teeth on the inside of the band body.

Further, as a method for eliminating the dead space described above, there is a resin binding band described in Japanese Utility Model Application No. 154269/1983.

However, although this band can be evaluated in terms of eliminating dead space in the bundled state, the teeth formed on the band body protrude toward the inner or outer periphery, so it may cause damage to the items to be bound or other items due to tightening. Not only is this undesirable as there is a high risk of causing abrasions, but when the insert portion is pulled during binding, the locking pawl in the head will be pressed more than necessary, which may damage the locking pawl.

This is because, as is well known, this type of cable tie is
For small ones, the external dimensions of the head are 3 mm x 4 mm x 5.
mm, and the locking pawl formed inside this small head is naturally extremely small, so especially near the base of the locking pawl, the stress limit of the material that forms it is near. This is simply because it is always designed.

Furthermore, as another conventional example, a binding device in which a group of teeth is formed on the side surface of the band base has been proposed, as seen in Japanese Utility Model Application No. 51-62986.

However, since the tooth group of this binding tool is exposed laterally, there is a high risk of damaging other items, and there is also a risk of damaging the locking pawl as in the conventional example mentioned above. Because there is a large clearance between the dimension of the through-hole in the head in the direction of the locking claw and the dimension in the width direction of the band body, if the band body enters diagonally with respect to the head, or If the band body is shaken in its width direction, there is a risk that the band body and the locking pawl may become disengaged.

This phenomenon is likely to occur not only when the locking claws are formed on the front and back sides of the band body, but also when the locking claws are formed on the side surface of the band body.

This is because the band body has greater rigidity in the width direction than in the thickness direction, so the posture of the band body can easily change even with a slight force.

As described above, each of the conventional examples has had many problems, but no means to solve them all at once has been found to date.

Therefore, the present invention eliminates dead space, does not damage other items, prevents excessive force from being applied to the locking pawl, and in addition, ensures reliable engagement. The purpose is to provide a cable tie that can solve problems at the same time.

[Means for Solving the Problem] The present invention for achieving this object includes a head having a through hole and a locking pawl facing into the hole, and a head extending from one end of the head and having a locking claw extending from one end of the head. It consists of a band base disposed in a position substantially parallel to the band base, and a band insert portion provided with a group of teeth that engage with the locking pawl within the through hole, and the group of teeth is arranged in a groove formed on the side surface of the band insert portion. and each tip of the tooth group is positioned so as not to protrude from the rib formed by providing the groove, while the locking pawl is provided at a position corresponding to the tooth group, and A binding band characterized by having a side wall formed by providing a through hole in the head at a position that guides the rib of the band insert part and near the locking claw. be.

Note that the band base and band insert of the present invention refer to those formed into one piece, or
Refers to both of those formed separately.

[Example] To explain the present invention with reference to the drawings, in FIGS. 1 to 4, one end of the band base 3 of the belt-like band 1 has a flat plate parallel to the longitudinal direction of the band base 3. A head 2 is formed. Furthermore, tooth groups 5 are formed on both sides of the band insert section 4 which is formed from the head section 2 through the band base section 3.

This tooth group 5 is arranged in grooves 4c formed on both sides of the band insert part 4, and the tip of each tooth is
Rib 4 formed by providing groove 4c
It is located at the same level as or lower than the end faces of a and 4b.

Furthermore, a through hole 6 is formed in the head part 2 in parallel to the band base part 3 and passing through the band insert part 4. Furthermore, a locking pawl 7 that engages with the tooth group 5 is disposed within the through hole 6.

On the other hand, by forming the through hole 6,
A side wall 2a is formed on the head 2 and serves as a support.
This position guides the end surfaces of the ribs 4a and 4b, and is located near the locking pawl 7.

Note that a repeating member 8 for releasing the locking of the locking pawl 7 extends behind the locking pawl. The binding band thus formed is integrally molded, for example, with plastic or the like. In the figure, 9 is a hole located at the fulcrum of the locking pawl 7 to relieve stress at the fulcrum.

5 and 6 are other embodiments of the present invention,
This embodiment is the same as that shown in FIG. 1 except that the position of the head 2 is reversed.

Further, as the repeat member 8 attached to the locking pawl 7 of the head 2, as shown in FIGS.
Alternatively, the locking pawl 7 may be opened by extending the repeating member 8 outward from the holder 8 or by extending the repeating member 8 outwardly or protruding at right angles to the head 2 as shown in FIG. Alternatively, as shown in FIG. 8, a notch may be formed in the plane direction of the figure, and the repeat member 8 may be exposed from there. Furthermore, as shown in FIG. 9, a curved elastic material 10 is placed between each of the locking claws 7,
Press this curved elastic material 10 (from the right side in Fig. 9)
The locking pawl 7 may be opened by doing this. Moreover, the tenth illustrated example shows a case where the repeat member 8 is not provided.

The band 1, the head 2, and others are all integrally molded from plastic, etc., as described above, but the materials used include polyamide,
Polypropylene and other thermoplastic resins, particularly those with high flexibility, are preferred.

Therefore, wires, strips, etc. are bound with the belt-like band 1,
When the band insert part 4 is passed through the through hole 6 of the head 2, the teeth 5 of the band insert part 4 are engaged with the locking claws 7 as shown in FIG. Since the ribs 4a and 4b are guided by the side wall 2a of the head 2, the band insert portion 4 does not swing from side to side within the head 2.
There is no rattling.

Therefore, since no overload is applied to the locking claw 7,
Breakage of the locking pawl 7 can be prevented, and since it does not rattle, there is no fear that the locking pawl 7 and the teeth 5 will come out of engagement. Furthermore, as shown in FIGS. 12 and 13, the belt-shaped band 1 and the head 2 are oriented in almost the same direction, and are securely bound without creating a dead space as in the conventional case.

In addition, the teeth 5 do not protrude from the ribs 4a and 4b, and there are no other sharp parts on the band base 3 or the band insert 4, so there is no possibility of damaging the objects to be bound or other articles. Nor.

Fig. 12 shows the case where the cable tie shown in the example shown in Fig. 1 is used, with the end of the band insert part 4 protruding outside, and Fig. 13 shows the case where the cable tie shown in the example shown in Fig. 5 is used, and the end of the band insert part 4 is exposed. The end of number 4 is inside.

In addition, the band insert part 4 and the band base part 3
Since it will not damage other things, if you attach a holder etc. (not shown) to hold the wristwatch near the center of the cable tie (near the bottom of Figures 12 and 13), you can secure the wristwatch. It can also be used as a band, and can be used in place of a wristwatch to hold, for example, the line number of an electric wire or the identification number of an infant at a maternity hospital.

On the other hand, if we explain another embodiment in which the above-mentioned binding band is suitable as a wrist watch band, the head 2 of the band base 3, the band insert part 4, and other structures are the same as those of the first illustrated example. In this example, this is divided into two approximately near the center, and a wristwatch holder is formed at each end of the two halves.

That is, FIGS. 14 to 16 show the band base 3 side of the binding band, and a hole 11 is formed at the bisected end into which the band attachment core rods on both sides of the wristwatch are inserted. The end of the band insert part 4 side, which serves as a holding part for the wristwatch, also has a head part 2 at its end, as shown in FIGS. 17 to 19.
A hole 11' similar to that on the side is formed.
The head portion 2 and the band insert portion 4 are connected as shown in FIG. 20, but there is no difference from the previous embodiment. For example, the state in which it is wrapped around the arm is the 21st
It will look like the figure. 12 indicates a wristwatch. Note that, as described above, in this embodiment as well, the wristwatch 1
2 may be replaced by the wire number of the electric wire or the infant's identification number at the maternity hospital.

[Effects of the invention] As described above, according to the invention of the present application, it is possible to tighten uniformly and reliably without creating a dead space unlike the conventional method and without damaging the objects to be bound, and the engagement is reliable. , you don't have to worry about it coming off.

Furthermore, since no overload is applied to the locking pawl, the locking pawl is prevented from being damaged, and its use can be expanded to include, for example, a watch band that is difficult to lock and release. It is something.
