BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting tool used, for example, when mounting a wire harness for in-vehicle wiring of an automobile on a vehicle body.

[0002]

2. Description of the Related Art The structure of a conventional fixture of this type is shown in FIG. Reference numeral 11 is an anchor member, and 12 is a substrate having a hole 13 into which the anchor member 11 is inserted. In this example, the anchor member 11 is formed integrally with the attachment plate 14 that is fixed to the wire harness (not shown) by tape winding.

The anchor member 11 has elastic locking pieces 16 extending obliquely upward from the lower ends of the pillar pieces 15 on both sides, and locking shoulders 17 are provided outside the upper ends of the elastic locking pieces 16. Has been formed. On the other hand, the hole 13 of the substrate 12 is formed in such a size that the locking shoulder portion 17 of the elastic locking piece 16 is caught on the edge of the back surface side of the anchor member 11 when the anchor member 11 is inserted.

When the anchor member 11 is inserted into the hole 13, the hole 13
6, the opening of the elastic locking piece 16 is narrowed as shown in FIG. 6, and after passing through the hole 13, the elastic locking piece 16 is widened as shown in FIG. It gets caught on the back edge.
As a result, the anchor member 11 cannot be pulled out of the hole 13 and is attached to the substrate 12.

The conventional mounting tool is easy to mount but difficult to remove. When attaching a wire harness to a vehicle body or the like, it may be necessary to remove it for various reasons after once attaching it. In such a case, it is possible to narrow the elastic locking piece of the anchor member and pull out the anchor member by inserting a hand or a jig on the back surface side of the substrate, but if this is not possible,
There is no method other than forcibly pulling out the anchor member, and there is a problem that the anchor member or the hole is damaged.

DISCLOSURE OF THE INVENTION The present invention provides a fixture which solves the above-mentioned problems, and comprises a anchor member and a substrate having a hole into which the anchor member is inserted. The anchor member has elastic locking pieces that extend obliquely upward from the lower ends of the pillar pieces on both sides, and has locking shoulders outside the upper ends of the elastic locking pieces. In the fixture, which is formed in such a size that the locking shoulder portion of the elastic locking piece is hooked on the edge on the back surface side when the anchor member is inserted, the edge of the hole on the back surface side of the board is , A guide piece that narrows the opening of the elastic locking piece to an opening that can pass through the hole is formed at a position that is circumferentially displaced from the position where the locking shoulder is caught when the anchor member is properly inserted. It is characterized by

[0007]

With this structure, when it becomes necessary to remove the anchor member, if the anchor member is twisted in the circumferential direction of the hole, the opening of the elastic locking piece is narrowed by the guide piece, so that the anchor member can be pulled out without difficulty. It becomes possible.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention. In FIG. 1, the same parts as those in FIG. 5 described above are designated by the same reference numerals. That is, the structure of the anchor member 11 and the substrate 12
The point that the hole 13 is formed is the same as the conventional one.

The feature of this attachment is that a pair of guide pieces 18 are formed at the edge of the hole 13 on the back surface side of the substrate 12. The guide piece 18 is formed on the edge of the hole 13 at a position deviated by approximately 90 ° in the circumferential direction from the position where the locking shoulder 17 is caught when the anchor member 11 is properly inserted. The distance between the facing surfaces of the pair of guide pieces 18 is the same as the inner diameter of the hole 13, or
It is smaller than that.

When the anchor member 11 is inserted into the hole 13, as shown in FIG.
As described above, the locking shoulder portion 17 of the elastic locking piece 16 is hooked on the rear surface side edge of the hole 13. This state is the same as the conventional mounting state shown in FIG. When it is necessary to remove the anchor member from this state, the anchor member 11 is twisted in the circumferential direction of the hole 13 by approximately 90 °. Then, as shown in FIG. 3, the elastic locking piece 16 is narrowed by the guide piece 18 to the same width as the inner diameter of the hole 13. Therefore, if the anchor member 11 is pulled in this state, it can be easily removed.

FIG. 4 shows another embodiment of the present invention. In this embodiment, a sufficiently large auxiliary hole 21 is formed in the substrate 12 so that the anchor member 11 is not caught even when the anchor member 11 is inserted, and a rotation preventing recess 22 is formed at the edge of the auxiliary hole 21. Then, the auxiliary ring 23 is attached to the auxiliary hole 21.

The outer diameter of the auxiliary ring 23 is almost the same as that of the auxiliary hole 21.
24 are formed. Further, the projecting piece 24 has a claw 25 that is hooked on the upper and lower surfaces of the substrate 12 when inserted into the recess 22. Therefore, when the auxiliary ring 23 is attached to the auxiliary hole 21 of the substrate 12, the auxiliary ring 23 is attached to the substrate by the action of the protruding piece 24 and the claw 25.
It does not come off from 12, and also does not rotate with respect to the substrate 12.

The auxiliary ring 23 is formed with a hole 13 into which the locking shoulder portion 17 of the elastic locking piece 16 is hooked when the anchor member 11 is inserted.
18 are formed. That is, this embodiment has a structure in which the anchor member insertion hole 13 and the guide piece 18 are formed in the substrate 12 via the auxiliary ring 23. Therefore, the anchor member 11
Can be attached and detached in the same manner as in the above embodiment. This embodiment is effective when the guide piece 18 cannot be directly formed on the substrate 12.

[0014]

As described above, according to the fixture of the present invention, after the anchor member is inserted into the hole of the base plate, when it becomes necessary to remove the anchor member, the anchor member is twisted in the circumferential direction of the hole. There is an advantage that the member can be easily removed from the substrate.
