[Industrial applications]

 The present invention relates to a binding band made of synthetic resin, which has a high binding strength by utilizing the tensile strength of the band body itself and can be unwound.

[0002]

[Prior Art]

 The synthetic resin binding band is a type that cannot be untied once it is used for binding electrical wiring, etc., and a rod-shaped body is temporarily bound and stored on a shelf in a warehouse. There is a type in which the binding can be unwound when using this rod-shaped body. The present invention belongs to the latter, but this type of binding band that can untie the binding supports the movable claw protruding into the through hole of the head so that it can be swung and operated behind the movable claw. In many cases, the piece is made to project, and when unwinding, the operating piece is operated to move the movable claw away from the teeth of the band body.

[0003] Thus, in the type of releasing the binding, the movable claw is swingable, so that the number of claws provided on the movable claw is one, and at most two claws are provided. The binding strength is not so strong because it is structured so that it can be rocked by an operating piece from the outside, and it was not suitable for applications requiring high strength.

[Problems to be solved by the device]

 On the other hand, when fixing a large number of protective sheets (curing sheets for construction work) stretched around the scaffolding at the construction site to the columns, tie them through the eyelets provided at the edge of the protective sheet with ropes. There is. Even with a small protective sheet, about 20 such eyelets are provided per sheet, and with a large protective sheet, there are as many as about 50 per sheet. It's quite complicated. In addition, the inner diameter of this eyelet is generally small, and the smallest standard is only 10 mm.Therefore, especially in a place where there is wind, the rope is inserted into the eyelet with a predetermined shape and a predetermined strength. The work of tying to requires a lot of skill and requires a long time.

In particular, there are few unskilled workers who have learned the special knotting method with high binding strength used in this connecting work. Moreover, there is almost no foreign worker who is unfamiliar with this type of work, which is increasing in the number of construction sites recently, who can connect the eyelets with a rope. Therefore, when we examined a method of binding by using other methods, instead of using a rope for the work to connect the eyelets and the pillars or to connect the eyelets to each other, we found that the binding made of synthetic resin used for binding electric wires, etc. Focused on the band. However, while the protective sheet is tied with this rope, there is a risk that dangerous materials may fall outside or jump out, and this protective sheet needs to be removed when the construction progresses to some extent. is there. On the other hand, when this building sheet or carpenter's tool falls from a high place, this protective sheet must meet the safety standards that prevent passersby from hitting those fallen objects. The rope tie strength should also be fairly strong. It is said that about 100 kg of strength to be supported by a single rope is required in the case of binding ordinary protective sheets.

As described above, it is clear that a considerable amount of force is required to bind the protective sheet rope used at the construction site with a rope, and it is possible to insert it into an eyelet having an inner diameter of about 10 mm. It was clarified that the unfastenable binding band could not exert its strength at all. This type of binding band consists of a head with a swingable movable claw, and a band body extended from this head, and this band body is inserted into the through hole of the head and attached to this band body. It is a mechanism that binds the formed teeth by meshing with the movable claws inside the head, and the binding force is obtained by the meshing force of one movable claw and at most two movable claws. .. Therefore, the binding strength due to the meshing force is much weaker than the tensile strength of the band body itself.

In view of the above problems, the present invention improves the binding strength due to the meshing force, which is an essential weakness of the binding band, while demonstrating the simple binding property of the binding band. The purpose of the present invention is to provide a binding band capable of exerting the tensile strength of the band body itself.

[0008]

[Means for Solving the Problems]

 To achieve the above object, the binding band according to the present invention is provided with a head at one end of a band body having a number of teeth continuous in the longitudinal direction, and the band body is inserted from the other end into the head. The two through holes are arranged side by side in the longitudinal direction of the band body, and the first through hole near the band body is provided with a movable claw capable of uncoupling with the tooth so that the second through hole is located laterally. A slit for inserting and removing the band body is opened on the inside, and a fixing claw that meshes with the tooth is provided inside, and is folded back in a U shape between the outlet of the first through hole and the inlet of the second through hole. In addition, a circumscribing bone that abuts in a pressed state is projectingly provided inside the folded portion of the band body.

[0009]

[Work]

 Since the binding band of the present invention has the above structure, the orbiting bone projecting between the outlet of the first through hole and the inlet of the second through hole is folded back in a U shape to fold the band body. By abutting against the inside of the return part in a pressed state and locking this over the entire width of this band body, it is possible to exert a strong binding strength by utilizing the tensile strength of the band body itself. Since the meshing force of the part where the teeth formed on the body and the movable claws and fixed claws formed on the head mesh with each other is added, it is possible to obtain a very high bundling strength while allowing the bundling state to be unwound. it can.

[0010]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of a binding band 1 of the present invention, in which a band body 2 has teeth 3 continuous in the longitudinal direction thereof, and a head provided at one end of the band body 2. The first through hole 5 and the second through hole 6 through which the band body 2 is inserted, and the movable claw 7 and the fixed claw 8 that mesh with the teeth 3 are formed inside the band 4. In addition, between the outlet 9 of the first through hole 5 and the inlet 10 of the second through hole 6, there is a circumscribing bone 11 that abuts against the inside of the folded portion of the U-shaped folded band body 2 in a pressed state. Has been formed.

The movable claw 7 formed inside the first through hole 5 meshes with the teeth 3 of the band body 2 when the band body 2 is inserted into the first through hole 5, and at the same time, the movable claw 7 is formed. An operation piece 12 is formed on the back surface of the movable member 7 so that it can be swung, and the movable claw 7 can be separated from the meshing portion with the tooth 3. When the operating piece 12 is pressed with a finger and pressed toward the band body 2, the movable claw 7 is unwound from the meshed state and separated from the tooth 3, and the band body 2 rubs the first through hole 5 smoothly. You will be able to escape.

A fixing claw 8 that meshes with the teeth 3 of the band body 2 is provided inside the second through hole 6, and the band body 2 is fitted into and removed from the side of the second through hole 6. A slit 13 is formed so as to allow the band body 2 to be unwound from the second through hole 6 of the head 4. Further, when the band body 2 is folded back in a U-shape and inserted from the outlet 9 of the first through hole 5 to the inlet 10 of the second through hole 6, the band body 2 is pressed against the inside of the folded portion, A circumscribing bone 11 for locking the band body 2 over its entire width is provided so as to project between the outlet 9 of the first through hole 5 and the inlet 10 of the second through hole 6, and constitutes this locking portion. By doing so, the band body 2 can be bound by utilizing the tensile strength of the band body 2 itself.

As described above, in addition to the tensile strength of the band body 2 itself that is abutted and locked to the orbiting bone 11 in a pressed state, it is provided inside the first through hole 5 and the second through hole 6, respectively. Since the movable claw 7 and the fixed claw 8 can also use the meshing force of the part of the band body 2 that meshes with the teeth 3 as an auxiliary, the banding band 1 has an extremely strong banding strength while allowing the binding state to be unwound. be able to.

When this binding band 1 is used, the tip of the circumscribing bone 11 is folded back in a U shape in order to sufficiently exert the tensile strength of the band body 2 itself as shown in FIGS. 4 and 5. When the movable claw 7 and the fixed claw 8 are brought into contact with the inside of the folded portion of the band body 2 and locked so that the deepest portion thereof is pressed, the load on the portion where the movable claw 7 and the fixed claw 8 mesh with the teeth 3 can be reduced. In addition to this, the tensile strength of the band body 2 itself can be effectively utilized.

Therefore, when using the binding band 1, first, the band body 2 is inserted from the other end into the first through hole 5 of the head 4 formed at one end of the band body 2, and then The band body 2 is folded back and inserted into the second through hole 6, and the teeth 3 of the band body 2 are meshed with the fixing claws 8 formed inside the second through hole 6. Then, the operation piece 12 on the back surface of the movable claw 7 formed inside the first through hole 5 is pressed toward the band body 2 side to temporarily release the meshing state of this portion, and the band body 2 is inserted. Pulling back slightly in the opposite direction, the orbiting bone 11 abuts against the inside of the folded portion of the band body 2 folded back in a U-shape in a pressed state, and locks it with the width of the band body 2. In this state, the hand is released from the operation piece 12, and the movable claw 7 inside the first through hole 5 and the tooth 3 of the band body 2 are engaged with each other.

In this way, the circumscribing bone 11 is pressed against the inside of the folded portion of the band body 2 folded back in a U shape, and the tensile strength of the band body 2 itself can be effectively exerted. Since the band body 2 can be locked by the above, the binding and unwinding can be repeated any number of times, while the tensile strength of the band body 2 itself can be sufficiently drawn out.

In the present embodiment, as shown in FIG. 6, the first through hole 5 is bound so that the teeth 3 of the band body 2 inserted into the first through hole 5 and the movable claw 7 are surely meshed with each other. A reduction step 14 is formed to reduce the width of the band 2 in the longitudinal direction to the amount corresponding to the thickness of the band body 2. Further, an inner inclined surface 15 is formed in the inner part of the second through hole 6 facing the slit 13 of the second through hole 6, and the tooth of the band body 2 inserted into the second through hole 6 is formed. The second through hole 6 of the band body 2 is formed by guiding the band body 2 in the direction of the fixed nail 8 so that the fixed piece 3 surely meshes with the fixed claw 8 and forming the surrounding projection 16 adjacent to the slit 13. It prevents accidental dropouts.
