Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a fastener for holding automobile carpets, wire harnesses, etc.

(Prior Art) An example of this type of fastener is shown in FIG. The one shown is a fastener for holding the wire harness W. This one has an overhang piece 30 for tying up the wire harness W. Also,
The main body 31 is formed in a cylindrical shape and can be inserted into a screw shaft 32 protruding from a fixed surface. Furthermore, inside the main body 31, a pair of locking claws 33 that can be engaged with the screw shaft 32 are provided.

(Problems to be solved by the invention) However, the above example is difficult to remove. This is because, since the fastener is engaged with the screw shaft 33, the entire fastener must be rotated in order to be removed. However, in the case of a type that holds a long object such as a wire harness W, as in this example,
This is because it cannot be rotated as it is.

Therefore, the only way to remove it is to cut the taping or forcefully pull it out. In this case, the locking claw 33 may be destroyed.
It also means that it cannot be reused. Further, re-taping is accompanied by significant difficulty.

Therefore, an object of the present invention is to provide a new fastener that can be easily separated from the body even while holding an object.

(Means for solving the problem) In order to achieve the above object, the present invention has a holding part for the object to be held, and by engaging with a locking shaft provided upright on the body side. This is a type of fastener that engages an object to be held with a body, and an insertion hole into which the locking shaft can be loosely inserted is coaxially formed from the lower surface of a cylindrical clip body that opens upward. At the same time, at least a pair of locking pieces that can be elastically engaged with the locking shaft are provided inside the clip body with an insertion hole in between, and the locking pieces are inserted inside the clip body as the clip is pushed in. The cap body, which is expanded to disengage from the locking shaft, is incorporated in a manner that prevents it from coming off.

(Function) Therefore, according to the above configuration, when the clip body is pushed into the locking shaft, the locking piece engages with the locking shaft, and as a result, the clip body and the object to be held are attached to the body. Fixed against. Further, the cap body is always housed in the clip body and engaged in a manner that prevents it from coming off.

On the other hand, when it becomes necessary to remove the fastener from the body, the cap body is further pushed in from its normal state. By doing so, the cap presses the locking pieces and bends and deforms them in the expansion direction. Therefore, the locking piece releases its engagement with the locking shaft. Thus, once the engagement with the locking shaft is released, the clip body can be easily pulled out from the locking shaft.

(Example) Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings.

The fastener C1 of the first embodiment consists of two members, a clip body 1 and a cap body 2, each made of a synthetic resin material.

First, to explain the clip body 1, the entire clip body is formed into a cylindrical shape, and a mounting piece 3 (holding part) for attaching the object to be held (wire harness W in this embodiment) is integrally formed at the lower end of the clip body 1. has been done. This attachment piece 3 is formed to a predetermined length,
The wire harness W can be tied down over an appropriate range.

The inside of the cap body 2 has a hollow part 4 that opens upward.
It can house a cap body 2, which will be described later.
Further, a window portion 5 passes through the side surface of the clip body 1. On the other hand, from the lower surface of the clip body 1, an insertion hole 7 into which a locking shaft 6 (a stud bolt in this embodiment) can be loosely inserted is coaxially passed through and communicated with the hollow part 4. are doing. A pair of locking pieces 8 are provided in the hollow portion 4 with the insertion hole 7 interposed therebetween along the opening direction of the window portion 5 .
Both locking pieces 8 are allowed to be elastically deformed in the direction of expansion, and each has a claw piece 9 integrally formed in the center of its opposing surface, so that it can be freely engaged with and detached from the locking shaft 6. Can be elastically engaged. In the natural state, both locking pieces 8 are slightly flared at their distal ends. This is because the surface on the distal end side (above the claw piece 9) of the locking piece 8 is used as the pressure contact surface 10, so that the lower surface of the cap body 2 can easily slide into contact with the same surface.

Furthermore, at a predetermined height position on the inner wall surface of the hollow portion 4, at least one protrusion 11 is integrally formed to protrude substantially perpendicularly to both the locking pieces 8.

The cap body 2 has a size that can be fitted into the hollow portion 4, and is formed in a cylindrical shape that opens only on the lower surface side. The lower cylindrical portion 12 is formed thin and can be slightly deformed. Moreover, two locking grooves 13u and 13l are recessed in the upper and lower sides of the outer periphery of the cylindrical portion 12 along the circumferential direction.
They can respectively engage with the protrusions 11 on the clip body 1 side. And, it is always locked with the lower locking groove 13l. At this time, the top surface of the cap body 2 is substantially flush with the top surface of the clip body 1.

Next, an example of actual operation of the fastener of this example will be explained. First, the wire harness W is tied to the attachment piece 3 of the clip body 1. Under this condition, hold the clip body 1, place the insertion hole 7 on the locking shaft 6, and push it firmly until the lower surface of the clip body B contacts the body B. By doing this, both claw pieces 9 engage with the locking shaft 6, so that the clip body 1 is fixed to the body B, and as a result, the wire harness W is fixed to the body B.
It will be securely fixed to. In this state, although the distal end side of the locking shaft 6 enters the cylindrical portion 12 of the cap body 2, there is a predetermined distance from the upper surface of the cylindrical portion 12.

Conversely, the work of removing the fastener is done as follows.

In this case, first push the top surface of the cap body 2 using a suitable tool such as a screwdriver to push down the entire cap body 2. Then, since the lower end of the cap body 2 comes into sliding contact along the pressing surfaces 10 of both locking pieces 8, both locking pieces 8 are pushed apart against the elastic force. By doing this, the engagement between the claw piece 9 and the locking shaft 6 is disengaged, and the projection 11 changes its engagement position from the lower locking groove 13l to the upper locking groove 13u. Therefore, this engagement can prevent the cap body 2 from coming off against the elastic reaction force of both locking pieces 8 acting on the cap body 2. In other words,
The disengaged state with respect to the locking shaft 6 is maintained. Thus, by lifting the fastener C1, it can be pulled out directly above the locking shaft 6. Therefore, even if the locking shaft 6 is a screw shaft, the fastener C1
Since it can be removed without rotating the fastener, it is particularly effective in the case of a long wire harness W (or pipe, etc.) where it is difficult to rotate the fastener.

After removing it, push the cap body 2 back to its original position with the tip of a screwdriver, etc., and the clasp will tighten.
C1 can be used again.

Although this example shows a case in which the wire harness W is attached to the locking shaft 6 in advance and then engaged with the locking shaft 6, the attachment work may be performed after the wire harness W is attached to the locking shaft 6. .

The one in Figure 4 is the fastener of the second embodiment of the present invention.
This indicates C2. This is particularly suitable for fixing a carpet, and has a presser piece 14 formed along the entire circumference at the upper edge of the clip body 1.

Note that the other configurations are substantially the same as those of the first embodiment, and the same effects as those of the first embodiment can be achieved.

Further, as an example of the locking shaft 6, it may be of the type shown in FIG. 5 or FIG. 6.

(Effect of the invention) As is clear from the above explanation, according to the present invention, the object to be held can be securely fixed to the body,
Moreover, since the engagement with the locking shaft can be released by simply pushing the cap body, the work of removing the fastener is extremely easy.
