[0004]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a wiring and piping clip which can be molded at a time and which is easy to produce, and a method for producing the clip.

[0005]

According to the clip for wiring and piping according to the present invention, one or a plurality of wires or pipes to be gripped by a holding member formed of a strip-shaped metal plate via an elastic body. In a clip for wiring and piping in which a gripping portion and a support portion fixed to a support at an end thereof are formed,
The elastic body is formed in a plurality of pillars extending in the width direction of the band-shaped bracket, and a gap is provided between adjacent pillars, and the grip portion of the bracket is gripped after the elastic body is formed. It is formed by molding into a shape that matches the external shape of the body.

[0006] The width of the gripping portion of the object to be gripped is made smaller as the gripping side of the object to be gripped approaches the object to be gripped.

Further, according to the method of manufacturing a clip for wiring and piping of the present invention, a grip for gripping a single or a plurality of wires or pipes through a resilient body is provided on a metal fitting formed of a strip-shaped metal plate. In a method for manufacturing a clip for wiring and piping having a portion and a support portion fixed to a support at an end thereof, a metal fitting processing step of processing a metal fitting into a plate shape, and forming a plurality of the metal fittings on the plate surface And an elastic body forming step of integrally forming an elastic body wrapping the metal fitting in the width direction of the band, and a shape in which the gripping part of the metal fitting integrally formed with the elastic body matches the outer shape of the object to be gripped. And a gripping part forming step of forming the same.

Therefore, according to the present invention, the elastic member can be formed by arranging the plate-like surfaces of the metal fittings in a molding die so as to face each other.
A large number of molds can be formed at once with a small mold. In addition, the elastic body that grips the object to be gripped is formed by a plurality of columnar bodies, and a gap is provided between adjacent columnar bodies, so that the gripped portion can be easily formed into an arc shape, and the stress of the elastic body is reduced. Can be reduced. Then, the object to be gripped from the columnar fitting,
That is, it is preferable to form the inner width narrower, because it can correspond to a smaller diameter. Since the forming of the gripping portion is the final step, it is possible to cope with various kinds of clips having different tube diameters and supporting dimensions from the state of the elastic body being formed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a clip C1 according to an embodiment of the present invention. The bracket 1 formed of a strip-shaped steel plate is provided with screw insertion holes 2A and 2B at both ends thereof for fixing to a support (not shown), and supports S1 and S2.
Are formed. Although the illustrated screw insertion hole 2A is formed as a long hole and can be adjusted, it may not be a long hole.

An elastic body 3 to be described later is integrally formed with the grip portion indicated by the reference character H, and the shape of the elastic body 3 is formed in an arc shape in accordance with the outer shape of a wiring or a pipe, which is a gripped body (not shown). This molding is performed after the elastic body 3 is integrally molded.

Further, both end support portions S1 and S2 of the metal fitting 1 are formed in an open state by springback,
At the time of fixation to the support, it is brought into close contact by tightening the screws, and the object to be grasped is grasped.

The elastic body 3 has a prismatic shape extending in the width direction of the metal fitting 1 formed of a strip-shaped steel plate, and a plurality of, for example, six columnar bodies formed around the edge of the metal fitting 1. 4
In the embodiment shown in FIG. 1, these pillars 4 are connected to each other by a connecting portion 5. And the connecting part 5
The width in the circumferential direction of the gripping object side, that is, the inner side, becomes narrower as approaching the gripping object, and is formed so as to be easily formed into an arc shape.

It is preferable that a hole 6 is provided in the metal fitting 1 as shown in FIG. 4 because the elastic body 3 and the metal fitting 1 are securely fixed and the columnar body 4 of the elastic body 3 is connected to each other. .

In the embodiment shown in FIG. 2, the shape of the elastic body 3A is different, and the width of the metal fitting 1 is fixed by only the columnar body 4, and is not connected to each other or connected only by the metal fitting width. ing. Therefore, it can be more easily formed into an arc shape.

FIG. 3 shows a columnar body 4B of the elastic body 3B.
In this embodiment, the shape is wider than that of the above-described embodiment, and three lines are formed.

Next, the manufacturing method will be described. First, the metal fitting 1 shown in FIG. 4 is plate-shaped, and the screw insertion holes 2A, 2B and the like are subjected to, for example, blank piercing (metal fitting processing step).

Then, as shown in FIG. 5, a plurality of plate-shaped fittings 1, 11 in the illustrated example,
Then, the elastic body 3 is formed by arranging the plate-shaped surfaces so as to face each other, and the metal fitting 1 and the elastic body 3 are integrally formed (elastic body forming step).

In this manner, as shown in FIG. 6, the metal fitting 1 and the elastic body 3 are taken out of the mold 10 in a state D in which they are integrally formed, and the gripping portion H is formed into a predetermined shape shown in FIG. .

This manufacturing method employs a clip C having an integrated shape of the elastic bodies 3C and 3D as shown in FIG. 7 or FIG.
4. Also applicable to C5 molding.

[0020]

The present invention is configured as described above,
The following effects are obtained. (1) Since a large number of pieces can be molded simultaneously, productivity is improved. (2) When the columnar elastic body is formed by wrapping the metal fittings, no bonding is required. (3) The elastic body is formed of a plurality of columnar bodies having a gap between each other, so that even with a small pipe diameter, the generation of stress due to bending is small and can be easily formed. In particular, if the inner diameter side of the columnar body is formed narrow, interference can be prevented, and a smaller diameter can be accommodated. (4) Since the forming of the gripping portion is a post-processing, it is possible to cope with clips having various pipe diameters and different supporting dimensions.
