[Prior Art]

 FIG. 13 shows a perspective view of the structure of the hose clip so far. In this figure, the clip body 50 is provided with an annular clamp portion 52 for clamping a hose (not shown) by its elasticity, and gripping pieces 54 formed at both ends of the clamp portion 52, respectively. . On the other hand, the holder 60 has a U-shaped holding portion 62.

Both gripping pieces 54 of the clip body 50 are aligned so as to be in the same position against each other against the elasticity of the clamp portion 52, and the holding portion 62 of the holder 60 is put on this. Then, the holder 60 is temporarily fixed by caulking the holding portion 62. In this state, the clamp portion 52 of the clip body 50 is held to have a maximum diameter. When the hose is clamped by the clamp portion 52 of the clip body 50, the holder 60 is removed from both gripping pieces 54 of the clip body 50. As a result, the clamp portion 52 is deformed by its elasticity in the direction of decreasing the diameter, and clamps the hose.

[0004]

[Problems to be solved by the device]

 In the hose clip shown in FIG. 13, due to variations in the strength (plate thickness or hardness) of the holding portion 62 of the holder 60 or the caulking force, etc., the gripping pieces 54 of the clip body 50 can be used to hold the holder 60. May come off easily or, on the contrary, may be difficult to remove. Therefore, the holder 60 may come off during transportation of the hose clip, or a large force may be required to remove the holder 60 when the hose is clamped.

The technical problem of the present invention is to reduce the production cost, to easily disengage the holder from the clip body with a small force when clamping the hose, and to clip the clip during transportation. It is to prevent the holder from coming off easily from the main body.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the hose clip of this invention has the following structure. That is, the clip body is provided with an annular clamp portion having a clamping force for clamping the hose due to its elasticity, and gripping pieces bent at both ends of the clamp portion, respectively, and is separate from the clip body. In a hose clip of the type in which the holder holds the clamp part in a state of being close to the maximum diameter against the tightening force, the holder is made of a single wire and both ends of the clip body are The holder is provided with engaging portions that can be engaged with each other, and this holder is attached to the clip body in a state in which one of the engaging portions has an elastic force in a direction to remove it from the gripping piece of the clip body. ing.

[0007]

[Action]

 According to the above construction, when the hose is clamped, both gripping pieces of the clip body are grasped by a tool such as a pliers, and the clamp part is once brought to the maximum diameter state. As a result, one engaging portion of the holder is disengaged from the gripping piece of the clip body by the elastic force of the holder. Therefore, the clamp portion in this state can be reduced in diameter based on the tightening force and can clamp the hose. Also, unless the clamp part of the clip body is once made to have the maximum diameter, the engaging part of the holder does not come off from the gripping piece of the clip body, and therefore the holder does not come off from the clip body during transportation of hose clips. .

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. Example 1 FIG. 2 shows a front view of the hose clip, FIG. 3 shows a left side view of FIG. 2, and FIG. 4 shows a right side view of FIG. In these drawings, a metal clip body 10 includes an annular clamp portion 12 and gripping pieces 14, 15 bent at both ends thereof. The clamp portion 12 has a clamping force for clamping a predetermined hose due to the elasticity of the clip body 10. The both gripping pieces 14 and 15 are connected to each other in the state shown in the drawing by a holder 20 formed of a single wire material such as a metal wire. As a result, the clamp portion 12 is held at a diameter slightly smaller than the maximum diameter against the tightening force.

Therefore, the structure of both gripping pieces 14 and 15 of the clip body 10 and the holder 20 will be described in more detail. First, FIG. 5 shows a part of FIG. 2 in an enlarged sectional view, FIG. 6 shows a part of the clip body 10 before attaching the holder 20 in a perspective view, and FIG. 7 shows the holder 20 in an enlarged plan view. Has been done. As is clear from these drawings, both the gripping pieces 14 and 15 are bent outward of the clamp portion 12. The one gripping piece 14 is located on the opposite side of the other gripping piece 15 through the opening 16 formed in the clip body 10, and both ends of the clamp part 12 are in a state of intersecting with each other. . When the clamp portion 12 is in the free state (state of the minimum diameter), both gripping pieces 14 and 15 are separated from each other by a predetermined distance as shown in FIG. An arcuate recess 14a is formed on both edges of the gripping piece 14, and a downward projecting piece 15a is integrally formed on the other gripping piece 15.

On the other hand, the holder 20 is formed by bending one wire (elastic material) as shown in FIG. 7 as described above. In other words, this holder 20 has the shape shown in FIG. 7 (A) in its free state, and by applying an external force in the direction in which both ends of the wire rod cross each other, FIG. 7 (B) shows. Elastically deforms like. In the state of FIG. 7B, the holder 20 is formed with a pair of left and right engaging portions 22 and 23 each having a loop shape. Of the engaging portions 22 and 23 of the holder 20, the engaging portion 22 that is formed by being surrounded by both ends of the wire rod further expands both end portions of the wire rod in the arrow direction of FIG. 7B. In this state, the clip body 10 is attached to one gripping piece 14 of the clip body 10. The engaging portion 22 is located at the concave portion 14a of the gripping piece 14, and strongly tightens the gripping piece 14 by the returning elastic force of the holder 20 to return to the state of FIG. 7 (A). At this time, the holder 20 is positioned substantially at right angles to the grip piece 14. The other engaging portion 23 of the holder 20 can be engaged with the projecting piece 15a formed on the gripping piece 15 of the clip body 10 from below.

In the holder 20, first, the engaging portion 22 is assembled to the gripping piece 14 of the clip body 10 as described above. After that, both gripping pieces 14 and 15 of the clip body 10 are made to approach each other against the tightening force of the clamp portion 12, and the engaging portion 23 of the holder 20 is engaged with the projecting piece 15a of the gripping piece 15 as shown in FIG. Let As a result, the clamp portion 12 is held in a state close to the maximum diameter as described above.

As described above, the holder 20 is elastically bent from a state substantially perpendicular to the gripping piece 14, and the engaging portion 23 thereof is engaged with the projecting piece 15 a of the gripping piece 15. Therefore, the engaging portion 24 is constantly exerted by the elastic force in the direction of removing it from the projecting piece 15a. However, the clamping force of the clamp portion 12 received by the holder 20 is large, and the engaging state of the engaging portion 23 with respect to the projecting piece 15a is maintained by this clamping force.

FIG. 1 is a perspective view showing a part of the clip body 10 to which the holder 20 is attached. In this drawing, the clamp portion 12 has the maximum diameter by grasping the tip end portions of the both gripping pieces 14 and 15 with a tool such as pliers and applying a force in the direction of the arrow. That is, when the two gripping pieces 14 and 15 are relatively close to each other to reach the state shown by the virtual line in FIG. At this moment, the engaging portion 23 disengages from the projecting piece 15a of the gripping piece 15, and the clamping portion 12 has its diameter reduced by the tightening force. Even in this state, the engaging portion 22 of the holder 20 remains attached to the grip piece 14.

When clamping the hose, it is sufficient to apply a force to both gripping pieces 14 and 15 of the clip body 10 in the arrow direction of FIG. 1 as described above. Therefore, the clamping work can be completed with a small force without the need for special dedicated tools. The holder 20 cannot be detached from the clip body 10 unless a force is applied to both gripping pieces 14 and 15 of the clip body 10 so that the clamp portion 12 has the maximum diameter. Therefore, it is possible to avoid a situation in which the holder 20 comes off the clip body 10 during transportation and the subsequent clamping work becomes difficult.

Embodiment 2 In the embodiment shown in FIG. 8, the gripping piece 15 of the clip body 10 is integrally formed with the upward protruding piece 15b. Therefore, the holder 20 is elastically bent from a state substantially perpendicular to the gripping piece 14, and the engaging portion 23 thereof is engaged with the projecting piece 15b of the gripping piece 15 from above. Therefore, if a force is applied to bring the gripping pieces 14 and 15 closer to each other, the engaging portion 23 of the holder 20 is disengaged upward from the projecting piece 15b due to the elasticity of the holder 20. In the second embodiment, the parts which are considered to have the same or equivalent configurations as those of the first embodiment are designated by the same reference numerals in the drawings, and the duplicated description will be omitted. Further, the same concept is applied to the following embodiments, and a duplicate description will be omitted.

Embodiment 3 In the embodiment shown in FIGS. 9 and 10, the engagement relationship between the gripping pieces 14 and 15 of the clip body 10 and the holder 20 is set to be opposite to that of the above-mentioned embodiments. ing. That is, in this embodiment, the engaging portion 22 of the holder 20 is assembled to the projecting piece 15b of the one gripping piece 15 in the clip body 10, and the holder 20 is fitted to the recess 14b of the other gripping piece 14. The engaging portion 23 of is engaged. Therefore, when a force is applied to bring the gripping pieces 14 and 15 of the clip body 10 closer to each other, the engaging portion 23 of the clip 20 is disengaged upward from the gripping piece 14 due to the elasticity of the holder 20.

Embodiment 4 In the embodiment shown in FIGS. 11 and 12, the engaging portion 23A of the holder 20 is rotated with respect to the pair of brackets 15c formed on both sides of the gripping piece 15 in the clip body 10. It is movably connected. The engaging portion 22A of the holder 20 is engaged with the other gripping piece 14 from above. Moreover, the holder 20 is formed with an arm portion 28 extended from one of the engaging portions 23A and locked to one side portion of the grip piece 15. As a result, the holder 20 is also given an elastic force in the direction of disengaging the engaging portion 22A from the gripping piece 14.
