Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding band, and more particularly, to a binding band in which another member can be attached to a member to be bound without excessive load.

[0002]

2. Description of the Related Art Conventionally, a so-called binding band has been used when two or more members, particularly, a linear member are bundled.

[0003] When binding a wire harness of an electric wire bundle, for example, a band portion is wrapped around the outer periphery of the wire harness, and the band portion is inserted into an engaging portion formed at a base portion of the band portion. By inserting and pulling out the distal end, the band is prevented from moving in the returning direction, and the wire harness is bound in a tight state.

[0004]

However, in such a conventional binding band, the outer periphery of a wire harness or the like is tightened substantially evenly by the band portion.

For this reason, for example, when assembling the wire harness with a tube member for which a hollow space needs to be secured, the band portion is wound around the outer periphery of the tube member together with the wire harness as usual. When this is done, the hollow space of the tube member is crushed, and the function of the tube member cannot be secured.

On the other hand, if it is attempted to bind the wire harness together with the wire harness while securing the hollow space of the tube member, the wire harness cannot be bound with a required tightening force.

For this reason, when assembling the tube member along the wire harness, separately from the binding of the wire harness itself, a tape is wound and fixed or the binding band is loosened so as not to crush the tube member. It has to be wound around and fixed, so that the operation cannot be performed easily and quickly, and unnecessary materials are also increased, which is a factor of high cost.

[0008] Therefore, the present invention, without tightening,
It is an object of the present invention to improve the workability and reduce the cost by enabling another member to be assembled along the member to be bound.

[0009]

Means for Solving the Problems A first method for solving the above problems is described below.
The present invention comprises a flexible band portion formed in a long length, and a locking portion provided at a base end portion of the band portion and engaging with the inverted band portion to lock the movement. A binding band for binding the member by winding the band portion around the outer periphery of the member and locking the locking portion at the locking portion at the base end portion, wherein the locking portion is formed from the base end portion of the band portion or the base end portion. One or two or more curved portions having a strength that bends in the extending direction of the band portion and maintains the curved shape even when the band portion is bound before the locking position of the band portion It is characterized by the following.

According to the present invention, even when the band is wound around the member to be bound and bound by a necessary tightening force, the band from the base end portion of the band to the locking position by the locking portion is required. One or more bends maintain a curved shape. Therefore, a tube member or the like required to secure a hollow space can be inserted and held in the curved portion, and can be assembled to a non-tied member such as a wire harness without depending on another material or another process. .

A second aspect of the present invention for solving the above-mentioned problems is characterized in that, in addition to the configuration of the above-mentioned first aspect, the curved portion is formed in a curved shape in which a part is opened.

According to the present invention, it is possible to insert the tube member or the like into a state where the tube member or the like is inserted from the opening of the curved portion. Therefore, a member to be tied, such as a wire harness, can be bound with the tube member kept in a state of being moved along without a complicated operation of inserting a long tube member from the distal end.

[0013] Here, the curved portion of the present invention means having a shape that is curved in the extending direction of the band portion.
Any shape including a sharply bent shape may be used as long as a space for inserting and holding another member adjacent to the binding space by the band portion can be secured.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 and 2 are views showing one embodiment of a binding band according to the present invention.

In FIG. 1, reference numeral 10 denotes a binding band formed by molding a resin material. The binding band 10 is formed to be long and flexible and has a sawtooth-shaped engaging groove 11a on one surface side. An engraved band portion 11, an insertion hole 12 a through which the inverted band portion 11 connected to the base end portion of the band portion 11 is inserted from the distal end portion, and the insertion hole 12.

By inserting and pulling out the wire harness W, the engaging claw 12b of the locking portion 12 can be engaged with the engaging groove 11a of the band portion 11 at a position where the wire harness W is tightened, and the band portion 11 moves in the returning direction. And a state in which the wire harness is tightly bundled can be maintained.

The binding band 10 is, for example, a tube member (assembly member) shown in FIG. 2 in which it is necessary to secure a hollow space from the engagement groove 11a of the band portion 11 to the locking portion 12 side.
In order to be able to completely accommodate T, a curved portion 13 having a curved shape which is curved in the extending direction of the band portion 11 and is opened with the diameter D of the tube member T is integrally formed. The wire harness W is formed so as to have a thickness t2 which is thicker than the thickness t1 of the other portions so that the wire harness W has a strength to maintain a curved shape without being greatly deformed even when a tensile force is applied. I have. In addition, this bending part 13
It is needless to say that not only the thickness may be secured to secure the strength but also a different material including a resin material may be used.

Therefore, as shown in FIG. 2, even when the band portion 11 is wrapped around the wire harness W and locked by the locking portion 12, as shown in FIG. The tube member can be inserted and held without being crushed, and the tube member can be assembled along the T together with the binding of the wire harness W using only the binding band 10.

In this case, the operation and effect of the present embodiment can be obtained in the same manner, and an operation of inserting the distal end into the curved portion 33 is required. The detachment of the tube member T can be reliably prevented.

Further, as a third other mode of the present embodiment, as shown in FIG. 4, the curved portion 43 is formed so as to open at an interval twice as large as the diameter D of the tube member T. In this case, the two tube members T can be inserted and held by the bending portion 43 and can be assembled in a state of being parallel to the wire harness W. The interval between the openings of the curved portion may be designed according to the convenience of the number of tube members T to be assembled.

Next, FIG. 5 is a view showing a second embodiment of the binding band according to the present invention. In addition, since the present embodiment is configured substantially in the same manner as the above-described embodiment, the same components are denoted by the same reference numerals, and the characteristic portions will be described.

In FIG. 5, the binding band 10 has a band portion 11 set to be longer than the outer periphery of the wire harness W.
The wire harness W is tied by forming the first wire 1a and locking it to the locking portion 12.

The binding band 10 is separated from the engagement groove 11a of the band portion 11 to the engagement portion 12 so as to be at a half interval of the outer periphery of the wire harness W, and between them. A pair of bending portions 13 are provided.

Therefore, as shown in FIG. 5, when the wire harness W is tightly bound, as shown in FIG.
The tube member T can be inserted and held in each of the pair of curved portions 13 and assembled in a state along both sides of the wire harness W (a positional relationship facing the outer periphery).

As described above, in this embodiment, in addition to the functions and effects of the above-described embodiment, two tube members T
Can be assembled along both sides of the wire harness W. Therefore, the tube member T can be easily attached to the wire harness W by designing the formation position and the number of the curved portions 13 in accordance with the wiring path of the tube member T to the wire harness W.

In this embodiment, the two curved portions 13
Will be described so as to be on both sides of the wire harness W. Needless to say, the present invention is not limited to this. The above-described bending portion 13 may be provided.
