[Industrial applications]

 This invention relates to a hose clip.

[0002]

[Prior Art]

 Various hoses are installed in the engine room of automobiles for supplying and discharging brake oil. Conventionally, metal hose clips have been used to connect these hoses, and simple tightening work has been performed by utilizing their spring properties. Here, the hose band is in a state where its diameter is reduced by its own spring action in the natural state (reduced diameter state), so if the hose band was transported to the site in its natural state, do not open the hose on the spot. The workability is poor. Therefore, it is required that the diameter of the hose be set so that it can be fitted into the hose as it is. Conventionally, there are two methods for maintaining the expanded state. One is a holder type such as Japanese Utility Model Laid-Open No. 64-29591, and the other is a holderless type that does not have such a holder and has a hose clip itself with a holding function. is there. Both of the above-mentioned types have a knob piece for expanding the diameter by bending both ends of the clip body outward at a substantially right angle. In the holderless type, both knob pieces themselves have detachable holding means.

[0003]

[Problems to be solved by the device]

 However, since such a knob piece is provided exclusively for expanding and deforming the clip body, it is rarely used after the hose is clamped except when repair or replacement of the hose occurs, and the hose of the hose is not used. After clamping, the tab itself is often a useless protrusion that is not normally used. And because of this protrusion, the surrounding space is always restricted, and when trying to mount the peripheral members after connecting the hose, in order to avoid interference with this, An extra space must be set around the hose clip in advance. In addition, the protrusions may interfere with the work and damage the members. This must be taken into consideration especially in hose clips applied in a narrow space such as an engine room.

Therefore, an object of the present invention is to provide a hose clip in which an unnecessary protruding portion is shortened as much as possible after the hose is clamped.

[0005]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object is formed by bending a substantially annular shape by a strip-shaped leaf spring material, and both ends thereof are bent outward and along substantially the circumferential direction. The clip body with the locking portion is formed, and the lower surface of the base portion is a locking groove that engages with both of the locking portions in the expanded state in order to hold the clip body in the expanded state. The holder is formed by opening both ends thereof, and the fixed operation piece is provided upright on the upper surface of the base in a direction orthogonal to the locking groove, and the movable operation piece that can face the fixed operation piece. The movable operation piece has a lower portion which is inserted from one end side of the locking groove, and a side edge of the locking portion in the locking groove is pushed by a pinching operation of the fixed operation piece and the movable operation piece. Push the body out of the holder to dissociate And it is characterized in that comprising a slider having a pressing piece.

[0006]

[Action]

 With the clip body expanded, insert both locking parts into the locking grooves of the holder and engage. As a result, the clip body is held in the expanded state. Before loading at the hose connection site, insert the slider pressing piece into the locking groove and integrate the clip body and slider with the movable operating piece and fixed operating piece facing each other. deep. Then, temporarily fit the entire hose clip to the mouth of the hose. When the fixed operation piece and the movable operation piece are operated to be pinched, the side edge of the locking portion is pushed by the pressing piece, and as a result, the clip body is pushed out and disengaged from the holder. As a result, the clip body returns to the reduced diameter state by its own spring force and the hose is tightened.

【Example】

 Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. The hose clip C of this example will be described as being used as a hose for supplying / discharging brake oil of an automobile, but it goes without saying that the applicable hose should not be limited to this. As shown in FIG. 2, the hose clip C of this example is composed of three members, a clip body 1, a holder 2 and a slider 3.

First, the clip body 1 will be described. The clip body 1 is formed by bending a strip-shaped leaf spring material into an annular shape, and a plurality of triangular windows 4 (two locations are opened in FIG. 2) on the peripheral surface. The installed example is shown). The triangular window 4 is a device for uniformly clamping the hose H, but since it is a well-known technique, its explanation is omitted. One end of the clip body 1 is a projecting piece 5 that is equally narrowed from both sides over a predetermined length range from the tip, and has a same curvature along the circumferential direction of the clip body 1. It extends so as to form a surface. However, the tip portion thereof bends outward obliquely upward, and then extends substantially along the circumferential direction again to form the first locking portion 6. A receiving groove 7 formed wider than the projecting piece 5 is opened at the other end side of the clip body 1 so that the projecting piece 5 is received in the central portion thereof and forms substantially the same peripheral surface as this. The tip portion of the portion where the receiving groove 7 is formed is bent obliquely upward to the outside similarly to the first locking portion 6, and is then extended again substantially along the circumferential direction. It is 8.

Next, the holder 2 will be described. The holder 2 is integrally formed of a synthetic resin material, and as shown in FIG. 1, a holder 9 formed to be wider than the width of the clip body 1 is used. Have A channel-shaped locking groove 10 is formed on the lower surface of the base portion 9 along the longitudinal direction (left-right direction in FIG. 1), and the locking groove 10 is formed on both sides of the clip body 1 in the expanded state. It serves to hold the clip body 1 in the expanded state by engaging with the locking portions 6 and 8, and has openings on the lower surface side and both end sides of the base portion 9, respectively. On the other hand, a fixed operation piece 11 is erected on the upper surface of the base 9 at one end side thereof over the entire width of the base 9. A guide groove 12 is provided on the upper surface of the base portion 9 for guiding a knob operation of the slider 3 described below. The guide groove 12 is provided right above the locking groove 10 along the locking groove 10 so as to communicate with the locking groove 10. One end side (opposite to the fixing operation piece 11) is open and the other end side is open. Has reached the fixed operation piece 11.

Finally, the slider 3 will be described. Like the holder 2, the slider 3 is also integrally formed of a synthetic resin material and has a movable operation piece 13 facing the fixed operation piece. A push piece 14 for pushing the clip body 1 out of the holder 2 extends forward from the lower surface of the movable operation piece 13, and the push piece 14 fits into the locking groove 10 and is located in the locking groove 10. It plays the role of pushing out the locking parts 6 and 8 that are stored and pushing out the clip body 1. The movable operating piece 13 and the pressing piece 14 are connected by a connecting piece 15 as shown in FIG. 1. The connecting piece 15 is formed narrower than the locking groove 10, and both the fixed and movable operating pieces 11, During the knob operation of 13, the knob operation is guided by sliding along the locking groove 10.

The hose clip C of the present embodiment configured as described above is carried to the work site for connecting the hose H by attaching the holder 2 and the slider 3 to the clip body 1 in the expanded diameter state. . In order to obtain such a form, first, the diameter of the clip body 1 is expanded, and both the locking portions 6 and 8 are inserted from one side of the locking groove 10 of the holder 2 and stored inside (the diameter expanding operation is performed. , Dedicated equipment.). At this time, the clip body 1 is inserted into the end of the holder 2 near the fixing operation piece 11. Next, the pressing piece 14 of the slider 3 is inserted into the locking groove 10, and the holder 2 and the slider 3 are integrated as shown in FIG.

At the connection work site, the hose clip C in the expanded diameter state is inserted into the mouth portion of the hose H 1 (as shown in FIG. 3), and is then fitted into the pipe P to be connected as it is. Then, when the fixed operation piece 11 and the movable operation piece 13 are picked up and the movable operation piece 13 is brought closer to the fixed operation piece 11 side (state of imaginary line in FIG. 1), the pressing piece 14 is engaged with the locking groove. In order to push the locking portions 6 and 8 in the clip 10, the clip body 1 is displaced along the locking groove 10 and is pushed out and disengaged from the clip body 1 when the knob operation is completed. Then, the clip body 1 returns to the reduced diameter state by its own spring force and tightens the hose H (state shown by an imaginary line in FIG. 1, see FIG. 4). As shown in these figures, after tightening the hose H, the locking portions 6 and 8 only slightly project, and the surrounding space is not damaged. Therefore, it becomes possible to allow a margin in the arrangement setting of the peripheral members to be mounted after this. In particular, since both locking portions 6 and 8 are extended in the circumferential direction, there is little fear of injury during the work of mounting the peripheral parts, and the work can be carried out smoothly and safely. Further, in this example, when the holder 2 and the slider 3 are separated from the clip body 1, no special work for separation is required, and it is possible by simply squeezing the operation pieces 11 and 13, so that the workability is excellent. It can be said that it is suitable for line work.

When the hose H needs to be repaired or replaced, the both locking portions 6 and 8 are slightly protruding, but they are protruded to the extent necessary for being pinched by a tool (plier or the like). Therefore, the diameter expansion operation is not made difficult.

[0014]

[Effect of the device]

 The effects of the present invention are as follows. The hose clip consists of a clip body for tightening the hose and a holder and a slider for holding and releasing the expanded state.When the hose is tightened, the holder and slider are clipped together. Since it has been separated from the above, unlike the past, no more protrusions than necessary are left after tightening the hose. As a result, a space around the clip can be secured, and the arrangement of the members around the clip can be afforded. In addition, it does not hinder the work of attaching peripheral members, which is useful from a work aspect.
