Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a U-shaped clip assembly.

U-shaped clips are used to secure multiple wires at specific locations, such as when securing spring wires to beds, easy chairs, automobile seats, etc.

FIG. 1 is a perspective view showing the wire secured using a U-shaped clip. In the figure, 1 is a peripheral wire, 2 is a spring wire, and 3 is a U-shaped clip for fixing the peripheral wire 1 and the spring wire 2.

FIG. 2 is a perspective view showing a U-shaped clip 3a of a conventional U-shaped clip assembly, and FIG. 3 is a sectional view thereof. This U-shaped clip 3a is made of a U-shaped curved plate such as a thin sheet metal, and has a curved portion 4 and legs 5a and 5b extending from the curved portion 4.
When the U-shaped clip 3a is in the fastened state, the leg 5a
is adapted to fit between the legs 5b.

FIG. 4 shows a conventional U-shaped clip assembly. In this U-shaped clip assembly,
A plurality of U-shaped clips 3a are arranged in a line adjacent to each other, and a holding member 6 made of a flexible material or the like is adhered to each curved portion 4 of the U-shaped clips 3a. are integrally formed. However, in this U-shaped clip assembly, since the adhesive area between the curved portion 4 and the holding member 6 is large, the radius of curvature of the bent portion 6a of the holding member 6 located between the U-shaped clips 3a is small, and the radius of curvature of the bent portion 6a of the holding member 6 located between the U-shaped clips 3a is small. The force holding the U-shaped clip assembly in a fixed configuration is weak. For this reason, when inserting the U-shaped clip assembly into a tightening device, the U-shaped clip 3a often falls sideways, as shown in Figure 5, which is a problem that tends to reduce the efficiency of tightening work. be. On the other hand, as shown in FIG. 6, when the adhesive area between the curved portion 4 and the holding member 6 is reduced, the adhesive strength becomes weaker, making it difficult to tighten the U-shaped clip assembly when transporting the U-shaped clip assembly. As shown in FIG. 7, the U-shaped clip 3a may come off from the holding member 6 when it is inserted into a mounting device, which is another problem that tends to reduce the efficiency of the tightening operation. Furthermore, when tightening the wire etc. with the U-shaped clip 3a using the tightening device,
When a person moves while using a bed or the like, the inner surface of the U-shaped clip 3a and the surface of the wire etc. rub against each other, which tends to generate unpleasant metal friction noise.

This invention was made to solve the above-mentioned problems, and is a U-shaped clip assembly that does not reduce the efficiency of tightening work and does not generate unpleasant metal friction noises during tightening or use. The purpose is to provide three-dimensionality.

In order to achieve this object, in the present invention, the semi-adhesive angle of the holding member is set to 12.5 to 50 degrees, and a thin layer made of a material that does not generate frictional noise with metal is provided on the inner surface of the plate.

Fig. 8 is a diagram showing a U-shaped clip assembly according to the present invention, Fig. 9 is a perspective view showing the U-shaped clip 3b of the U-shaped clip assembly shown in Fig. 8, and Fig. 10 is a sectional view. be. In this U-shaped clip assembly, the U-shaped clip 3b is drawn from the center of curvature O of the curved portion 4 of the U-shaped clip 3b.
The angle formed by the center line l ₁ and the line l ₂ connecting the center of curvature O and the point where the holding member 6 separates from the curved portion 4, that is, the semi-adhesion angle θ, is set to 12.5 to 50 degrees. Further, on the inner surface of the plate, a thin layer 7 made of a material such as vinyl chloride, rubber, paper, felt, fake leather, etc. that does not cause frictional noise with metal is provided.

In this way, since the semi-adhesive angle θ is set to 12.5 to 50 degrees, it is possible to maintain a good balance between the retention of the form of the U-shaped clip assembly and the adhesive force between the U-shaped clip 3b and the holding member 6. That is, since the radius of curvature of the bent portion 6a becomes larger, the holding member 6
The force for holding the U-shaped clip assembly in a predetermined fixed configuration is strong, and the U-shaped clip 3b will not fall sideways, such as when inserting the U-shaped clip assembly into a tightening device. In addition, since the adhesive area between the curved part 4 and the holding member 6 is quite wide, the adhesive force between the curved part 4 and the holding member 6 is strong, and the U-shaped clip assembly can be tightened when the U-shaped clip assembly is transported. The U-shaped clip 3b does not come off from the holding member 6 when it is inserted into the device. Furthermore, since the thin layer 7 is provided on the inner surface of the plate, when the U-shaped clip 3b is fastened, the plate does not directly contact the wire, but the thin layer 7 comes into contact with the wire.

As explained above, in the U-shaped clip assembly according to the present invention, the U-shaped clip does not fall sideways when the U-shaped clip assembly is inserted into the tightening device, and the U-shaped clip assembly When transporting a solid object or inserting the U-shaped clip assembly into a tightening device, the U-shaped clip does not come off from the holding member, so the efficiency of the tightening work can be greatly improved. moreover,
The plate of the U-shaped clip does not come into direct contact with the wire, etc., but the thin layer does, so when tightening the wire, etc. with the U-shaped clip using a tightening device, there is no need for people to use the device on a bed, etc. There is no unpleasant metal friction noise when the metal is moved. As described above, the effects of this invention are remarkable.
