[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding band made of synthetic resin which has high binding strength by utilizing the tensile strength of the band itself and can be unwound.

[0002]

2. Description of the Related Art A tying band made of a synthetic resin is used for bundling electric wiring and the like and cannot be unwound once tied. There is a type in which the rod can be stored and untied when the rod is used. The present invention belongs to the latter, but a binding band of a type capable of unwinding the binding movably supports a movable claw projecting into a through hole in the head, and an operation piece behind the movable claw. In many cases, the operating piece is operated to separate the movable claw from the teeth of the band body when unwinding.

[0003] The type in which the binding is unwound as described above has a movable claw that can swing, so that the number of claws provided on the movable claw is one, and at most two. Since it is configured to be swingable by an operation piece from outside, the binding strength is not so strong, and it is not suitable for applications requiring a large strength.

[0004]

[Problems to be Solved by the Invention] On the other hand, when a large number of protective sheets (curing sheets for construction work) stretched around a scaffold at a construction work site are fixed to a support, they are provided at the edges of the protective sheets. This is tied to the eyelet through a rope. About 20 such eyelets are provided per sheet even for a small protective sheet, and about 50 pieces per sheet for a large protective sheet. It is quite complicated. Also,
The inner diameter of this eyelet is generally small, and the smallest standard has a diameter of only 10 mm.In particular, in a place where there is wind, the work of inserting a rope through the eyelet and tying it to a predetermined shape and a predetermined strength Requires considerable skill and requires a long time.

[0005] In particular, few unskilled workers have learned a special tying method having a high binding strength used in this connection work. In addition, there is hardly any foreign worker who is unfamiliar with this kind of work, which has recently been increasing at construction sites, and who can connect this eyelet with a rope. Therefore, we examined a method of binding by using other methods without using a rope between the eyelet and the strut or between the eyelets, and found that a synthetic resin binding band used for binding electric wires etc. We paid attention to. However, the period in which the protective sheet is tied with the rope is a period during which there is a risk that dangerous substances may fall or jump out, and it is necessary to remove the protective sheet when construction proceeds to some extent. On the other hand, this protective sheet must meet the safety standards established so that when building materials or carpentry tools fall from high places, they do not hit the surrounding pedestrians. The bond strength must also be quite large. In the case of bundling ordinary protective sheets, it is said that the strength supported by one rope needs to be about 100 kg.

As described above, it is clear that the binding strength of the protection sheet used at the construction site by the rope requires a considerably large force, and it is possible to insert the protection sheet into an eyelet having an inner diameter of about 10 mm. It has become clear that the binding band that can be unwound cannot exhibit its strength at all. This type of binding band is composed of a head having a swinging movable claw and a band extending from the head, and this band is inserted into a through hole in the head to form this band. This is a mechanism that meshes with the movable teeth in the head and binds them to the teeth that are set, and the binding force is obtained by the engagement force of one and at most two movable claws. Therefore, the binding strength due to the engaging force is much lower than the tensile strength of the band itself.

[0007] In view of the above problems, the present invention is to improve the binding strength of the binding band, which is an essential weakness of the binding band, while exhibiting the simple binding property of the binding band. It is an object of the present invention to provide a binding band that can exhibit the tensile strength of the band itself.

[0008]

In order to achieve the above object, a binding band according to the present invention is provided with a head at one end of a band body having a plurality of teeth continuous in a longitudinal direction, and the head has a head. Two through holes for inserting the band body from the other end are arranged side by side in the longitudinal direction of the band body, and a movable claw that meshes with the teeth so that the teeth can be unwound is provided inside the first through hole near the band body. 2
A slit for engaging and disengaging the band body is opened on the side of the through hole, and a fixed claw that meshes with the teeth is provided on the inner side.
A peripheral bone is protruded between the exit of the through hole and the entrance of the second through hole.
The band body is inserted into the first through hole and the second through hole,
U-shaped formed between the outlet of the through hole and the inlet of the second through hole
When the folded part of the band body folded back is tightened
A configuration which is adapted to abut a pressing state inside the folded portion in the circumferential bone.

[0009]

[Operation] Since the binding band of the present invention has the above configuration, the orbital bone projecting between the exit of the first through hole and the entrance of the second through hole is folded back into a U-shape. By pressing against the inside of the folded portion of the band body in a pressed state and locking it over the entire width of the band body, it is possible to exert a strong binding strength using the tensile strength of the band body itself, Since the meshing force of the portion where the teeth formed on the band body and the movable claw and the fixed claw formed on the head mesh with each other is supplementarily added, it is possible to obtain a very high binding strength while enabling the binding state to be unwound. Can be.

[0010]

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. FIGS. 1 to 3 show an embodiment of the binding band 1 of the present invention, in which a band body 2 is formed with continuous teeth 3 in its longitudinal direction, and a head 4 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 a movable claw 7 and a fixed claw 8 that mesh with the teeth 3 are formed inside the first through hole 5 and the second through hole 6, respectively. Between the outlet 9 of the first through-hole 5 and the inlet 10 of the second through-hole 6, there is a revolving bone 11 which abuts against the inside of the folded portion of the band body 2 folded in a U-shape in a pressed state. Is formed.

Movable claw 7 formed inside first through hole 5
When the band body 2 is inserted through the first through hole 5, an operating piece 12 is formed on the back surface of the movable claw 7 so as to mesh with the teeth 3 of the band body 2 and to allow the movable claw 7 to swing. The movable pawl 7 can be separated from the meshing portion with the teeth 3. When the operation piece 12 is pressed by a finger and pressed in the direction of the band body 2, the movable claw 7 is unwound from the meshing state and separates from the teeth 3, and the band body 2 smoothly passes through the first through hole 5. Will be able to do it.

A fixing claw 8 is provided inside the second through hole 6 to engage with the teeth 3 of the band 2, and the band 2 is fitted to and removed from the side of the second through hole 6. The band 13 is formed with the second slit of the head 4.
It can be unwound from the through hole 6. Further, when the band body 2 is folded back into a U-shape from the outlet 9 of the first through hole 5 to the inlet 10 of the second through hole 6 and is inserted, the band body 2 is pressed against the inside of the folded portion, and A revolving bone 11 for locking the band body 2 over its entire width is provided between the outlet 9 of the first through-hole 5 and the entrance 10 of the second through-hole 6 to constitute this locking portion. Thus, the band 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, which is brought into contact with the orbiting bone 11 in a pressed state and locked, the first
The movable claw 7 and the fixed claw 8 provided inside the through hole 5 and the second through hole 6, respectively, can also use the meshing force of the portion meshing with the teeth 3 of the band body 2 in an auxiliary manner, so that the binding state is unwound. A binding band 1 with extremely strong binding strength while enabling
It can be.

When this binding band 1 is used, as shown in FIGS. 4 and 5, the tip of the orbiting bone 11 is folded back in a U-shape in order to sufficiently exert the tensile strength of the band body 2 itself. Abut the inside of the folded part of the band body 2
When the locking is performed in such a state that the deepest portion 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, and the tensile strength of the band body 2 itself can be effectively used. can do.

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, The band body 2 is folded back and inserted through the second through hole 6, and the teeth 3 of the band body 2 are engaged with the fixed 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 to temporarily unwind the meshing state of this portion, and the direction in which the band body 2 is inserted. Pull back slightly in the opposite direction of
Abuts against the inside of the folded portion of the band body 2 folded in a U-shape in a pressed state, and releases the hand from the operation piece 12 in a state of locking the band body 2 at the width thereof. ,
The movable pawl 7 inside the first through hole 5 and the teeth 3 of the band body 2 are engaged.

In this manner, the orbiting bone 11 abuts against the inside of the folded portion of the band body 2 folded in a U-shape in a pressed state, so that the tensile strength of the band body 2 itself can be effectively exerted. Since the band body 2 can be locked, the binding and unwinding can be repeated any number of times,
The tensile strength of the band body 2 itself can be sufficiently brought out.

In this embodiment, as shown in FIG.
In order to ensure that the teeth 3 of the band 2 inserted into the through hole 5 and the movable claws 7 mesh with each other, the width of the first through hole 5 in the longitudinal direction of the binding band 2 is equivalent to the thickness of the band 2. There is formed a reduction step 14 that reduces the size to the maximum. Further, the second through hole 6
A guide inclined surface 15 is formed in the inner part of the second through hole 6 facing the slit 13 of the second embodiment, and the teeth 3 of the band body 2 inserted into the second through hole 6 are securely connected to the fixed claws 8. The band body 2 is guided in the direction of the fixed claw 8 so as to mesh with each other.
The surrounding projection 16 adjacent to the slit 13 is formed to prevent the band body 2 from accidentally falling out of the second through hole 6.
