Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a U-shaped clip assembly including a plurality of U-shaped clips for tightening and fixing elongated members, for example, two wires, and particularly to a U-shaped clip assembly that is integrally provided with a plurality of U-shaped clips for tightening and fixing two wires. This invention relates to an improved U-shaped clip assembly.

2. Description of the Related Art Fixing multiple wires at predetermined locations, such as fixing spring wires in beds, easy chairs, car seats, etc., is often done when assembling various products.

For fixing wires, etc., clips curved into a U-shape have been widely used.

FIG. 1 is an explanatory diagram showing the state in which the U-shaped clip is attached.

In the figure, 1 is a spring wire, 2 is a wire to which the spring wire 1 is attached, and 3 is a U-shaped clip for fastening the spring wire 1 and the wire 2 together.

The configuration of a conventional U-shaped clip will be briefly described below.

FIG. 2 is a perspective view of the U-shaped clip disclosed in Japanese Patent Publication No. 48-30960, and FIG. 3 is a longitudinal sectional view of the U-shaped clip shown in FIG.

Figure 4 also shows the U-shaped clip proposed by the applicant.
That is, Japanese Patent Application No. 52-6744 C Japanese Patent Application No. 53-939
No. 2) Perspective view of the U-shaped clip described in the specification, No. 5
The figure is a longitudinal sectional view of the U-shaped clip shown in FIG. 4.

The U-shaped clip shown in FIGS. 2 and 3 is made of thin sheet metal and has a curved portion 4, that is, an arched mid-height portion, and a pair of extension portions 5, 6 extending slightly outwardly from the curved portion 4. The tip of the extension part 5 has two legs 7 and 8 by cutting out the central part.
The tip of one long section 6 is cut out on both sides to form a single leg 9 in the center.

When the clip is tightened, the single leg 9 fits between the two legs 7 and 8.

In addition, the U-shaped clip shown in FIGS. 4 and 5 has a thin layer 10 made of a material that does not produce fricative noise, such as vinyl chloride, rubber, or paper, on the inner surface of the U-shaped clip made of thin sheet metal shown in FIGS. 2 and 3. , felt, fake leather, etc., and have the effect of preventing frictional sounds, or squeaks, caused by contact with a predetermined wire.

The U-shaped clip shown in FIGS. 2 and 3 or 4 and 5 described above is usually used in an assembly as shown in FIG.

As shown in the figure, such a U-shaped assembly consists of U-shaped clips arranged in a row adjacent to each other so that their top and bottom shapes are the same. It is integrally constituted by a single holding member, such as a flexible material 11, which is bonded to one surface via an adhesive.

7 and 9 are side views each showing an example of a conventional U-shaped clip assembly.

In the assembly shown in FIG. 7, the adhesive area 12 of the adhesive part between the curved part 4 of the U-shaped clip and the flexible material 11 is small, and therefore the adhesive strength is weak, so that it may be difficult to transport or assemble the assembly. When inserting a three-dimensional object into a predetermined tightening device, there is a problem in that the U-shaped clip tends to come off as shown by the arrow 12a in FIG. 8, which tends to reduce tightening efficiency.

In addition, in the assembly shown in FIG. 9, contrary to the assembly shown in FIG. The force holding the assembly in a fixed configuration is weak, i.e. the micro-bends 13 of the flexible material 11 located between the clips.
These clips tend to bend in the direction of arrow 14, so when inserting them into a fastening device, etc.
As shown in Figure 5, the bolts often fall sideways, which is a problem that tends to reduce the efficiency of the tightening work.

The present invention has been made in view of the actual state of the prior art, and its purpose is to provide a U-shaped clip assembly that can prevent the U-shaped clip from coming off and improve tightening efficiency. It is about providing.

Hereinafter, the U-shaped clip assembly of the present invention will be explained in detail based on the drawings.

FIG. 11 is a side view showing one embodiment of the assembly of the present invention.

The clips constituting this assembly are similar to the clips shown in Figs. 2 and 3 above or the clips shown in Figs. 4 and 5, and the holding members for holding these clips are the same as those shown in Figs. It is made of the same material as the flexible material 11.

However, in the present invention, the bonding range between the clip and the flexible material 11 is specified as described below.

First, as shown in FIG. 11, when a U-shaped clip is placed so that its curved portion 4 is positioned upward, and cut parallel to its open side surface 16, that is, in a direction parallel to the plane of FIG. Imagine a plane formed by

A circle 17 shown by a broken line is included in this plane, and a circle inscribed in the curved portion 4, 18 is the center point of this circle 17.

That is, this center point 18 is the center of curvature of the curved portion.

19 is the highest point of the curved part 4, and 20 shown by a chain line is the center point 18 of the circle 17 mentioned above and the point 1 on the curved part 4.
This is the fourth straight line connecting 9.

Similarly, 21 and 22 shown by chain lines are on the plane that includes the circle 17. and the second and third straight lines passing through the center point 18 of the circle 17, and the second and third straight lines 2 1.2
2 and the first straight line 20, the respective angles 23 and 24
are almost equal.

Furthermore, these angles 23.24 are between 12.5° and 50°.
i.e., the second straight line 21 and the third straight line 21
The angle 25 formed by the straight line 22 is set within the range of 25° to 100°.

Then, the assembly of the present invention is assembled into the virtual second,
Third straight line 21. The flexible material 11 is bonded only to the outer surface of the curved portion 4, which is formed by moving the arcuate portion 26 of the curved portion 4 surrounded by the curved portion 22 in a direction perpendicular to the plane of FIG. 11. be.

In the U-shaped clip assembly constructed in this way,
The inventors have found that the adhesive force between the clip and the flexible material 11 and the force that holds the assembly together are well balanced.

As described above, according to the U-shaped clip assembly of the present invention, two wires passing through the center of curvature of the curved portion of the U-shaped clip, for example, the center point of the inscribed circle, are drawn at an angle of 25° to 100°. When a straight line is imagined, only the outer surface of the curved part formed by moving the arcuate part of the curved part surrounded by these two straight lines in a direction perpendicular to the open side surface of the U-shaped clip has flexibility. The parts are glued together, making it easy to transport. Alternatively, there is no risk of the clip coming off when inserted into the tightening device, and at the same time, the form of this assembly is maintained well, so there is no risk of the clip falling sideways, which has the remarkable effect of significantly improving tightening work efficiency. play.
