Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement of a clip that is inserted into a temporary fixing portion of a hose tightening band (hereinafter referred to as a hose band).

[Prior Art] As shown in FIG. 9, the temporary fixing part 9 of the hose band 1 which has a conventional temporary fixing function has a flange part 4 at one end of the annular main body, and a locking claw 8 on the support frame 7 at the other end. A clip 22 is inserted into the temporary fixing portion 9 to prevent the temporary fixing from coming off. As shown in FIG. 10, this clip 22 is made of metal or resin and is formed into a U-shape, and as shown in FIG.
Both open ends 22A, 22A are caulked and inserted as shown in FIG. 9.

[Problems to be solved by the invention] However, since the above-described conventional clip 22 caulks the opening ends 22A, 22A,
There was a problem that attaching the clip 22 was troublesome. Furthermore, when the temporary fixing is removed, there is a danger that the clip 22 will fly off, and the diameter of the main body of the hose band 1 that has been removed from the temporary fixing is reduced, making it impossible to insert it into the hose.

Therefore, the object of this invention was to solve the above-mentioned problems of conventional clips in hose bands. To provide a clip for a hose band which can maintain an enlarged diameter state and can be used as a hose band.

[Means for Solving the Problems] The means of the present invention for achieving the above-mentioned problems is such that the main body is a spring material formed in an annular shape with opposite ends for tightening the hose, and the main body is temporarily fixed in an enlarged diameter state. The hose band has a temporary fixing portion formed by a flange provided at one end of the main body and a locking claw of a support frame provided at the other end, and the flange portion is locked to the locking claw to be in a temporarily fixed state. The clip is inserted into the temporary fixing part of the main body, and is made of a strong material that can withstand the spring force of the main body and has a certain degree of deflection characteristics, and is formed into a cylindrical shape surrounding the outer shape of the temporary fixing part forming member, and has an inner side. The clip for the hose band temporary fixing part is provided with a retaining part that comes into contact with a part of the temporary fixing part forming member to prevent the clip from coming off.

[Function] The clip inserted into the temporary fixing part is prevented from coming off by the retaining part, and when the temporary fixing part comes off, the flange part comes into contact with one side of the inside of the clip, and the inside of the clip is The support frame comes into contact with the opposing surface, and further movement of the flange portion and the support frame is stopped.

Further, when the temporary fixing is removed, the clip is subjected to a spring force in the opposite direction by the flange portion and the support frame, and the retaining portion bites into the temporary fixing portion forming member, and since the clip is cylindrical, it does not come off.

[Example] Next, an example of the present invention will be described based on FIGS. 1 to 8.

In FIG. 1, a hose band 1 provided with a temporary fixing part 9 and a clip 12 inserted into the temporary fixing part 9 are shown. The hose band 1 has a narrow protruding piece 3 at one end, and a notch 5 for inserting the protruding piece 3 at the other end.
The main body 2 is a receiving piece 6 having an annular shape with both ends facing each other, and a spring material for tightening the hose, in this example a band-shaped spring. In addition, 1
0 and 10 are punched holes in the main body 2. A small flange portion 4 is bent outward at the tip of the protruding piece 3, and a frame-shaped support frame 7 is formed at the tip of the receiving piece 6.
is bent outward. A locking pawl 8 is formed at the upper end of the support frame 7 by bending it downward from the upper end on the back surface of the support frame (the surface opposite to the surface facing the flange portion).
The lower end of the locking pawl 8 and the upper end of the flange portion 4 can be locked. The temporary fixing part 9 consists of the flange part 4 and the locking claw 8 of the support frame 7.

The main body 2 of the hose band 1 in the temporary state is enlarged in diameter, and the hose band 1 when inserted into the hose is
is in this state (see hose band 1 in Figure 1). In addition, hose band 1 after removing the temporary fixing
As shown in Fig. 2, due to the spring force of the main body 2,
The hose 19 has a small diameter, and the spring force tightens the hose 19 to the connecting pipe 20 as shown in FIG.

The clip 12 is made of a strong material, such as polypropylene, which can withstand the spring force of the main body 2 and has a certain degree of flexibility, and is formed into a cylindrical shape surrounding the outer shape of the temporary fixing portion 9 forming member. That is, as shown in FIGS. 4 to 6, the clip 12 of this example
A flat plate part 13 that covers the surface of the support frame 7 (the surface facing the flange part), a bent side plate part 14 that covers the side and back surfaces, the locking claw 8 in a locked state, and the flange part 4
It is integrally formed into a cylindrical shape with a convex planar cross section. The center of the lower end of the flat plate part 13 is notched to form an insertion groove 16 for the protruding piece 3, and an inclined retaining part 17 protruding outward is formed at the center of the upper end of the inner surface. The protruding plate part 15 has a protruding lower end that is elongated downwardly than the flat plate part 13, and the lower end is connected to the main body receiving piece 6.
The projecting plate portion 1 can be inserted into the notch portion 5 of the
The lower portion of the inner surface of the flange 5 is formed into a thick wall portion 18 so as to be able to abut and support the locked flange portion 4 when it comes off.

As shown in FIG. 7, the clip 12 of this example is placed on the temporarily fixed hose band 1 support frame 7 and inserted so as to surround the support frame 7, the locking claw 8, and the flange portion 4. . When inserting clip 12,
The retaining portion 17 contacts the support frame 7, but by press-fitting the clip 12, the flat plate portion 13 of the clip 12 is bent, allowing the clip to pass through the support frame 7. The inserted clip 12 has the lower end of the protruding plate part 15 connected to the receiving piece 6.
into the notch 5 and into the insertion groove 1 of the flat plate part 13.
6 is inserted into the protruding piece 3, and the retaining portion 17 abuts the upper bent portion of the locking pawl 8, so that the fixing property is good and normally it does not come off.

As shown in FIG. 8, when the locking pawl 8 and the flange portion 4 come off due to the action of an external force, the support frame 7 moves together with the locking pawl 8 in the direction of arrow L, and the flange portion 4 moves in the direction of arrow R, but the support frame 7 touches the inner surface of the flat plate part 13 of the clip 12,
The flange portion 4 is received in contact with the inner surface of the protruding plate portion 15, particularly the thick portion 18, and the expanded diameter state of the main body 2 is maintained. Since the locking pawl 8 is provided on the opposite side of the spring-acting support frame 7, it does not participate in contact with the inner surface of the clip 12. In addition, as shown in FIG. 8, the clip 12 of this example is designed so that the upper end of the flange portion 4 which has been temporarily removed comes into contact with the upper end of the thick portion 18 on the inner surface of the protruding plate portion 15. The spring action of 4 is stopped at this part.

The clip 12 with the flange portion 4 removed is in a somewhat deformed and tensioned state because the support frame 7 and the flange portion 4 act as springs in opposite directions within the cylinder, but the support frame 7 is cylindrical and made of strong material. and the flange portion 4 can be sufficiently received. In addition, when the flange portion 4 of the clip 12 comes off, the support frame 7 and the flange portion 4 move in the opposite direction, so that the retaining portion 17 of the flat plate portion 13 of the clip 12 is attached to the locking claw 8.
Clip 12 that bites into the inside of the upper end bend
Strengthen the prevention of removal.

Thus, the hose band 1 with the clip 12 inserted therein can be inserted into the hose 19 because the main body 2 maintains its enlarged diameter state even after the temporary fixing part 9 is removed. After the main body 2 is inserted into the hose 19, the clip 12 inserted into the hose band 1 can be easily removed by pulling strongly upward with pliers or the like. With the temporarily fastened hose band 1 from which the clip 12 has been removed, the flange portion 4 can be removed from the locking claw 8 and the hose 19 can be fastened to the connecting pipe 20 in the same manner as in the prior art.

[Effects of the invention] Even if an external force is applied to the temporarily fastened portion of the hose band during product transportation or before the hose clip is inserted into the hose during the assembly process, it will not easily come off.

Even if an external force is applied and the temporary fixing part comes off, the hose clip maintains its enlarged diameter state, so the hose clip can be inserted into the hose without having to be replaced.
