[0018]
As shown in FIG. 1, the clip 1 is formed of, for example, a synthetic resin injection molded product or the like, and has a holder portion 10 for holding a linear body such as a hose or a wire harness. This holder part 10 has an opening 10a in which a part of a cylindrical wall part is cut out along the axial direction, and the edge of the opening 10a is widened outward to facilitate the introduction of a linear body. Yes. That is, the linear body is configured such that a portion to be fixed is pushed from the opening 10 a and is elastically held by the holder 10 to be held.
[0019]
One end of the fixed portion 11 is connected to a part of the outer periphery of the holder portion 10 along the axial direction. The fixing portion 11 extends outward with respect to the holder portion 10, and an insertion port 14 for the bracket 2 is formed at the protruding end portion. The fixed portion 11 includes a bottom wall 15a, both side walls 15b rising from both sides of the bottom wall 15a, a protruding portion 15c that bends inward from the upper end of the both side walls 15b, and an opening formed between the protruding portions 15c. 16 and has a box shape with an upper surface and an end surface opened as a whole.
[0020]
And the guide groove 17 which receives the front-end | tip part of the bracket 2 is formed of the both-sides edge part of the bottom wall 15a, both-side wall 15b, and the protrusion part 15c. The bracket 2 is inserted into the guide groove 17 at both side edges and inserted from the insertion port 14. Accordingly, the bracket 2 can move in the directions of arrows A and B in FIG. 1, but is not movable in the vertical direction in FIG.
[0021]
On the other hand, a cantilever-like engagement piece 12 having a fixed end on the insertion port 14 side is formed in a punched shape at the center portion of the bottom wall 15a of the fixed portion 11, and the engagement piece 12 includes An engagement protrusion 19 and an operation protrusion 13 are provided. As shown in FIGS. 1 and 2, the engagement protrusion 19 includes an inclined surface 19 a that protrudes toward the opening surface 16 toward the free end of the engagement piece 12, and a substantially upper portion of the inclined surface 19 a. And a stepped portion 18 that falls vertically.
[0022]
Further, an operation protrusion 13 is provided in the middle of the free end of the engagement piece 12 in the width direction so as to protrude in a plate shape at a position across the inclined surface 19 a and the stepped portion 18. The operation protrusion 13 protrudes in a substantially vertical direction with respect to the bottom wall 15a through the opening surface 16, and is easily operated by pushing a finger or the like.
[0023]
The bracket 2 is formed of a plate-like member such as metal, and a base end portion (not shown) is fixed to a predetermined place such as a car body of an automobile with a bolt or the like, and the clip 1 is attached to a distal end portion. A rectangular engagement hole 21 is formed at a position at a predetermined distance from the end edge at the distal end portion. Further, a notch 22 that reaches the engagement hole 21 from the end edge is formed at the center in the width direction of the tip of the bracket 2.
[0024]
Next, the usage method of this linear body fixing tool is demonstrated.
First, the base end portion of the bracket 2 is fixed to a predetermined location such as a vehicle body (not shown) with a bolt or the like. And the front-end | tip part of the bracket 2 is inserted toward the arrow A direction of FIG. At this time, both side edges of the bracket 2 are sandwiched between the guide grooves 17, and the bracket 2 is slidable in the insertion direction and fixed in a direction perpendicular to the insertion direction.
[0025]
If the insertion is continued, the leading edge of the bracket 2 will eventually come into contact with the inclined surface 19a. At this time, since the bracket 2 is fixed in a direction orthogonal to the insertion direction, the engagement piece 12 which is cantilevered by being pushed by the tip edge of the bracket 2 bends downward. When the engagement protrusion 19 of the engagement piece 12 gets over the inner edge 23 of the engagement hole 21 of the bracket 2, the deflection returns due to the elasticity of the engagement piece 12, and the step 18 engages with the inner edge 23. Accordingly, the bracket 2 is prevented from coming off from the clip 1. At this time, the operation protrusion 13 of the engagement piece 12 moves through the cut portion 22 communicating with the engagement hole 21, and is positioned in the cut portion 22 in the engaged state, thereby contributing to prevention of rattling of the clip 1. To do. Thus, attachment of the clip 1 to the bracket 2 is achieved.
[0026]
Next, a portion to be fixed of a linear body such as a hose or a wire harness is inserted into the holder portion 10 of the clip 1 through the opening 10a, and the linear body is elastically held in the holder portion 10. Thus, the linear body can be fixed to a predetermined location such as a vehicle body via the clip 1 and the bracket 2. In addition, the linear body can be previously held in the holder portion 10 of the clip 1, and the clip 1 can be inserted into the bracket 2 and fixed in that state.
[0027]
Further, when it is necessary to remove a linear body such as a hose or a wire harness at the time of maintenance of a vehicle or the like, the linear protrusion is held on the operation projection 13 while being held in the holder portion 10 of the clip 1. When the finger is applied and pulled in the direction of arrow C in FIG. 2, as shown in FIG. 3, the engagement piece 12 that is cantilevered is bent again, and the engagement protrusion 19 comes out of the engagement hole 21, 18 and the engagement hole 21 are disengaged, and the bracket 2 can be extracted in the arrow B direction. Thus, the linear body can be removed by a one-touch operation. Further, after the maintenance is completed, the linear body can be fixed with one touch by inserting the clip 1 into the bracket 2 again as described above. Therefore, the linear body can be attached and detached easily and quickly, thereby eliminating the possibility of damaging the linear body.
[0028]
FIG. 4 is a side sectional view showing a linear body fixing device according to another embodiment of the present invention with a clip attached to a bracket. In the following description of the embodiment, the same reference numerals are given to substantially the same parts as those in the above embodiment, and the description thereof will be omitted or simplified.
[0029]
In this embodiment, although the engagement hole 21 is formed in the front-end | tip part of the bracket 2, the above-mentioned notch part is not provided. That is, the engagement hole 21 is a hole that is completely surrounded by a peripheral edge without an open portion directed toward the tip edge. Then, the engagement piece 12 of the clip 3 extends in parallel to the bottom wall 15a of the fixed portion 11 from the peripheral wall of the holder portion 10, and the imaginary portion of FIG. It is possible to bend as shown by the line. Further, on the lower surface of the engagement piece 12, an engagement protrusion 19 that protrudes toward the bottom wall 15 a of the fixing portion 11 and engages with the engagement hole 21 of the bracket 2 is formed. On the upper surface, an operation protrusion 13 is formed that protrudes in a direction opposite to the engagement protrusion 19 and substantially perpendicular to the engagement piece 12. Note that the guide groove into which the bracket 2 is inserted is configured by a frame-shaped insertion portion including a bottom wall 15a of the fixing portion 11, both side walls (not shown), and an upper wall 15d. Further, when viewed in plan, the engagement piece 12 has a shape in which the upper wall 15d is cut out in a U shape to form a cantilever shape.
[0030]
According to this embodiment, when the distal end portion of the bracket 2 is inserted into the frame-shaped insertion portion from the insertion port 14 of the fixing portion 11, the engagement protrusion 19 of the engagement piece 12 is pressed against the upper surface of the bracket 2, After the engagement piece 12 bends upward, when the engagement protrusion 19 fits into the engagement hole 21, the return is elastically restored, and the deflection is restored. The bracket 2 is prevented from coming off by engaging with the inner edge 23. Therefore, the clip 3 can be fixed to the bracket 2 and a linear body (not shown) can be held and fixed to the holder portion 10.
[0031]
Further, when the clip 3 is detached from the bracket 2 and the linear body is removed, a finger is put on the operation projection 13 and pulled in the direction of arrow D, and the engagement piece 12 is bent as shown by an imaginary line in the figure. That's fine. As a result, the engagement protrusion 19 is disengaged from the engagement hole 21 and the bracket 2 can be pulled out.
[0032]
In this embodiment, since the operation protrusion 13 is formed on the surface opposite to the engagement protrusion 19, it is not necessary to provide a notch in the bracket 2, so that the processing of the bracket 2 is facilitated and the strength of the bracket 2 is increased. Can be prevented from decreasing.
[0033]
FIG. 5 is a side cross-sectional view showing still another embodiment of the linear body fixture according to the present invention in a state where a clip is attached to a bracket.
[0034]
This linear body fixture has basically the same structure as the embodiment shown in FIGS. 1 to 3 except that the engagement hole 21 of the bracket 2 is not provided with a notch that reaches the tip edge. The point and the operation protrusion 13 of the engagement piece 12 are formed in the free end of the engagement piece 12, and the engagement protrusion 19 is formed in the intermediate part of the engagement piece 12. FIG. That is, the engagement piece 12 of the clip 4 has a cantilever shape formed in a punched shape on the bottom wall 15 a of the fixing portion 11, and the operation protrusion 13 stands substantially vertically from the free end of the engagement piece 12. The engaging piece 12 is bent as indicated by an imaginary line in the drawing by pulling the operating projection 13 in the direction of arrow C in the drawing. Further, the engagement protrusion 19 is formed at the intermediate portion in the length direction of the engagement piece 12 away from the operation protrusion 13 toward the proximal end side, and the engagement protrusion 19 is fitted into the engagement hole 21 of the bracket 2. In the combined state, the operation protrusion 13 is in a position where it does not interfere with the bracket 2. The structure of the guide groove or the like for receiving the bracket 2 is the same as that of the embodiment shown in FIGS.
[0035]
In this linear body fixture, since the operation protrusion 13 is provided at a position where it does not interfere with the bracket 2, it is not necessary to provide a cut portion extending from the engagement hole 21 of the bracket 2 to the tip edge of the bracket 2. Similarly to the embodiment, the bracket 2 can be easily processed and the strength of the bracket 2 can be prevented from being lowered.
[0036]
FIG. 6 is a plan view showing a further embodiment of the linear body fixing device according to the present invention with the clip removed from the bracket.
[0037]
This linear body fixture also has substantially the same structure as the embodiment shown in FIGS. The only difference is that the notch 22 extending from the engagement hole 21 of the bracket 2 to the leading edge of the bracket 2 is formed eccentrically toward one side from the middle in the width direction of the bracket 2, and In addition, the operation protrusion 13 of the clip 1 is also formed eccentrically toward any side from the middle in the width direction of the engagement piece 12.
[0038]
That is, the operation protrusion 13 can be inserted into the cut portion 22 of the bracket 2 only when the bracket 2 is inserted into the guide groove from the insertion port 14 and the front and back of the clip 1 are directed in a certain direction. As a result, the assembly direction of the clip 1 with respect to the bracket 2 is determined, and the clip 1 cannot be fixed by turning the front and back of the clip 1 upside down. Therefore, the clip 1 can be fixed only in a state where the front and back of the clip 1 are directed to the bracket 2 in a specific direction, and an assembly error of the clip 1 can be prevented. For this reason, even when the holder part 10 is connected to the fixed part 11 at various angles, the holder part 10 can be surely arranged at a predetermined position. It is possible to avoid inconveniences such as being unable to fix or shifting the fixing position of the linear body.
[0039]
As described above, in the present invention, the holder portion 10 can be connected to the fixing portion 11 at various angles and positions. For example, the holder portion 10 can be connected to the bottom surface 15a of the fixing portion 11 with one peripheral surface of the holder portion 10. You may connect so that a part may contact | connect.
[0040]
