The support member 40 is formed in a stepped shape in the upper portion of the guide plate 53a, and then the support member 40 is seated on the locking portion 55, and then caught.

That is, the locking portion 55 is the support member 40 is mounted, after the band body 10 is a force to open both sides to the opposite side of the tightening direction is acting,

In this case, the coupling member 30 and the supporting member 40 are lifted upward and subjected to a force to rotate.

In order to prevent this, the locking portion 55 supports the upper surface of the supporting member 40 to prevent the supporting member 40 from moving upward, thereby supporting the supporting member 40 at the locking portion 55. At the same time prevents

By fixing and supporting the supporting member 40, the tightening force by the coupling member 30 and the supporting member 40 is transmitted to the guide member 50 to tighten the band body 10.

Hereinafter, as illustrated in FIGS. 3 and 4, the band body 10 is bound to the bending object through interaction with the coupling member 30, the supporting member 40, and the guide member 50 according to the present invention. This operation will be described.

First, a plurality of coupling members 30 are connected to the one supporting member 40,

The coupling member of the coupling member 30 and the supporting member 40 connected as described above may be pivoted using the support rod 20 as the rotation axis.

In this case, the supporting member 40 is positioned at one end of the coupling member 30, that is, at the other end of the band main body 10,

When both sides of the band body 10 are pulled or pushed by applying a constant force in a direction in which both sides of the band body 10 are tightened, that is, both sides of the band body 10 face each other, both sides of the band body 10 are close to each other ( In this case, the operation of pulling or pushing the band body 10 is to use the following support knob (80).

At this time, if the support member 40 and the coupling member 30 is rotated by pressing the support rod 20 as the rotation axis from the upper direction to the lower direction,

The supporting member 40 is passed to the rear end of the guide portion 53 of the guide member 50, the bolt 31 of the coupling member 30 is inserted into the guide portion 53 of the guide member 50 ,

When the external force is removed in this state, the band body 10 is opened by elasticity, and the supporting member 40 is mounted on the locking portion 55, and the supporting member 40 is supported by the locking portion 55. do.

In this case, however, the supporting member 40 may be directly mounted to the locking portion 55 while being passed to the rear end of the guide portion 53 of the guide member 50.

Next, when the bolt 31 and the nut 33 which are the coupling member 30 are tightened, the guide member connected to the other side of the band main body 10 at one end of the bolt 31 on which the supporting member 40 is mounted. On the other end of the bolt 31 connected to the support rod 20, the band main body 10 can bind the banding object by pulling and tightening one side of the bond main body in a direction facing each other.

In this process, the bolt 31 as the coupling member 30 is guided by the guide portion 53 of the guide member 50 and is stably supported.

Furthermore, as shown in FIGS. 1 to 4, in the binding band according to the present invention, a close contact member 60 is provided between both bottom surfaces of the band body 10 and the banding object.

The band body 10 is arranged between a space between both side portions of the band body 10 and the band body 10 which is not in contact with the band object, and a lower surface portion of the band body 10 and a banding object. It acts to give a binding force in the space between the two sides of.

The contact member 60 for this purpose is a flexible member 61 in contact with the bending object, and

It is connected to the upper portion of the flexible member 61, is arranged on the lower surface of both sides of the band body 10 is made of a reinforcing member (63) for supporting the flexible member (61).

First of all, the flexible member 61 is preferably made of rubber or a member having a constant elasticity such as an elastomer.

However, when the band body 10 is tightened, both side portions of the band body 10 move in a direction close to each other,

The flexible member 61 is a space between both side portions of the band body 10 due to friction between a lower surface of both side portions of the band body 10 and a banding object due to the characteristics of the material. There is a problem that the space is raised or lifted up without being pushed or overlapped completely.

Therefore, in the present invention, the reinforcing member 63 is introduced to solve the problem of using only the flexible member 61 as described above.

The movement will take place.

Therefore, the flexible member 61 is maintained in close contact with the bending object, thereby solving the problem that the flexible member 61 is pushed or overlapped as described above, so that both sides of the band body 10 are fixed. It is possible to ensure the strengthening of the binding force in the space between the parts.

Meanwhile, when the adhesive member 60 is introduced as shown in FIGS. 1 to 4, the adhesive member 60 does not surround the entire bending object.

The space between the two side portions of the band body 10 and a size that can cover only a predetermined region of the lower surface portion of both sides of the band body 10 is produced.

In this case, the close contact member 60 is positioned at the correct position, that is, the space between both sides of the band main body 10 and arranged in a virtual center line, and then the close contact member 60 when tightening the band main body 10. ) Is not fixed and can be out of position,

In addition, when the flow range of the contact member 60 is increased, the binding force in the space between the both sides of the bond body may be a problem.

Therefore, in the present invention, when the band body 10 is tightened, the contact member 60 is in the correct position during the operation of tightening the band body 10 by introducing a positioning means 70 for precisely positioning the contact member 60. It is desirable to be able to arrange to.

The positioning means 70 for this purpose is formed on the body 51 of the guide member 50 and the reinforcing member 63 of the contact member 60,

A positioning pin 71 connected to the reinforcing member 63 of the contact member 60;

It is connected to the body 51 of the guide member 50, it is formed to correspond to the positioning pin 71 and comprises a positioning hole (73) into which the positioning pin 71 is inserted.

That is, the positioning means 70 is inserted into the positioning hole 73 formed on the guide member 50, the positioning pin 71 formed on the contact member 60 side when tightening the band body 10. ,

At this time, it is preferable that one end of the positioning pin 71 is connected to the center line or half of the reinforcing member 63 based on the width direction, or to be connected to a position adjacent to the center line.

This means that the connection point of the positioning pin 71 is located between both sides of the band body 10 in any case when the band body 10 is completely tightened.

In this case, when the connecting point of the reinforcing member 63 and the positioning pin 71 is formed on or near the center line of the reinforcing member 63 as described above.

Since the close contact member 60 is naturally arranged in the correct position, it may not take extra effort or care to position the close contact member 60 when the band body 10 is tightened. Can be guaranteed.

Furthermore, as shown in Figures 1 to 4, the guide member 50 according to the present invention is further provided with a support handle 80,

When the support member 40 is pushed or pulled in the direction in which the other side of the band main body 10 is tightened in order to mount the support member 40 to the locking portion 55 of the guide member 50, the operator holds the support handle 80. The operation is made convenient by allowing the force to be applied by holding the.

The support handle 80 is connected to the guide member 50, more precisely the front end of the guide plate 53a of the guide 53,

Among the guide plates 53a, the guide plates 53a are connected to two guide plates 53a positioned at an intermediate point along the longitudinal direction of the band body 10.

Therefore, in order to pivot the coupling member 30 and the supporting member 40 to mount the supporting member 40 on the engaging portion 55, the support handle 80 is held by the worker, and then the band body ( The supporting member 40 is pulled or pushed in the direction opposite to the support handle 80 while pushing or pulling by applying a force in the direction of clamping the other side of 10). By this operation, the supporting member 40 may be easily mounted to the locking portion 55.

At this time, pushing or pulling the support handle 80 is in accordance with the direction to hold the worker support handle 80,

This means that it is possible to conveniently perform the work according to the work direction determined by the work situation or the status of the worker.
