Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for mounting a member to be mounted on a mounting panel, and more particularly to a clip which can be mounted by pressing a mounting hole.

[0002]

2. Description of the Related Art Clips of this kind are classified into single members as shown in FIG.
Are roughly divided into two members. The former clip 50 is composed of a head portion 51 and a shaft portion 52, and is provided with a hole locking flange 53 in multiple vertical stages with respect to the shaft portion 52.
The clip 50 is attached to the mounting panel P
Is mounted on the mounting panel P by pushing the shaft portion 52 into the mounting holes M1 and P1. In the mounting operation, the shaft 52 is pushed into the mounting holes M1 and P1 with the swinging displacement of the flange 53, and the mounting is completed when the head 51 hits the member M to be mounted. On the other hand, the latter clip 60 is a female member 61 having a cylindrical body 62 penetrating vertically and a flange 66 provided on the upper and outer circumferences of the body 62, and the flange 60 and the body 62. And a male member 65 having a shaft 67 that can be inserted. The body portion 62 is divided into a plurality of swinging pieces 64 by a vertical slit, and a locking claw 6 provided at a protruding end of the swinging piece 64 is provided.
4a. The shaft portion 67 has a main retaining groove 69 provided at a substantially intermediate peripheral portion and a temporary retaining concave portion 68 provided at a peripheral portion of the distal end. From the temporarily fixed state in which the claw 64a is engaged with the temporarily fixed concave portion 68 (the state in which the swinging piece 64 is not expanded and deformed), the claw 64a is further engaged with the permanent groove 69 as shown in FIG. Therefore, after the clip 60 is inserted into the mounting holes M1 and P1 in the temporarily fixed state, the mounting member M is mounted on the mounting panel P by pushing the male member 65 into the body 62. In the mounting operation, the shaft portion 67 is pushed into the body portion 62 with the swinging displacement of the swinging piece 64, and
The mounting is completed when 9 engages with the locking claw 64a.

[0003]

The above-described clip 50
The fixing or locking force (hereinafter, referred to as a fixed holding force) is proportional to the swing displacement of the flange 53 with respect to the hole diameter of the mounting holes M1, P1, and the stronger the flange 53 is, the larger the hole diameter and the thicker. Becomes However, in this structure, the difference between the pushing force of the shaft portion 52 to the mounting holes M1, P1 and the pulling force is small,
If the pressing force is designed to be small in order to improve the mounting property, the fixed holding force is also reduced. Also, the mounting hole M
1, the fluctuation of the fixed holding force due to the variation in the hole diameter of P1 becomes remarkable. In the mounting operation, there is a possibility that the head 51 may not be in close contact with the mounted member M in the mounted state, due to lack of moderation at the end of the insertion of the shaft portion 52.

The fixed holding force of the clip 60 is proportional to the amount of displacement of the rocking piece 64 with respect to the diameter of the mounting holes M1, P1, and the force of engagement between the locking groove 69 and the locking claw 64a. at the same time,
The male member 65 is switched from the temporarily fixed state to the fully locked state with the swing of the rocking piece 64, and the displacement of the rocking piece 64 in the diameter reducing direction is restricted by the presence of the shaft 67 in the fully locked state. Therefore, the above-mentioned moderation feeling is excellent, and the fixed holding force can be made larger than the pressing force. However, in this structure, for example, if the member to be mounted M is a vehicle ceiling trim material or a side trim material, and the specification is such that a plurality of members can be mounted to a roof panel or a side panel serving as the mounting panel P, the clip 60 is If the clip 60 is simply inserted into the mounting holes M1 and P1 from the temporarily fixed state, it will fall out or tilt, so each clip 60 must be inserted into the mounting holes M1 and P1 in order and immediately pushed to the final locking state. That is, in the mounting operation, the clips 60 are temporarily fixed to the mounting holes M1, P1, and thereafter, the clips 60 cannot be permanently fixed, so that the operation procedure and the like are restricted. Further, in this structure, when the amount of radial expansion displacement of the rocking piece 64 is increased and the fixed holding force is further strengthened, the pushing force of the male member 65 is increased and the workability is deteriorated. In addition, when the thickness of the member to be mounted M or the thickness of the mounting panel P is different, the amount of displacement of the rocking piece 64 changes and the fixed holding force also fluctuates.

[0005] An object of the present invention is to solve the above-mentioned problems. Specifically, it has the advantages of both clips 50 and 60 described above, and at the same time,
The object of the present invention is to eliminate all of the problems of the present invention, and to realize a clip excellent in handleability, mounting workability, versatility and fixed holding force. Other objects will be clarified sequentially in the following description.

[0006]

In order to achieve the above object, the present invention is, as shown in the drawings, used for attaching a member to be attached 2 to a panel 3, and includes a tubular body 11 vertically penetrated and A female member 10 having a flange portion 12 provided on the upper and outer circumferences of the body portion 11, wherein the body portion 11 is prevented from falling out of the mounting hole 3 a of the panel 3, a large head 21 and the body portion 11 In the clip 1 comprising the male member 20 having the shaft portion 22 which is inserted so as to be able to be prevented from being pulled out, the female member 10 is provided so as to protrude around the body 11 so as to protrude from the panel 3.
The mounting claw 14 is reduced in diameter into the body while being pressed against the mounting hole 3a, and is restored and engageable when passing through the mounting hole 3a.
a, and a locking claw 15 provided on the distal end side of the body 11, wherein the male member 20 is connected to the body 1 of the shaft 22.
Among the shaft parts inserted into the first part 1, the upper shaft part 22a has an outer diameter that regulates the diameter of the mounting claw 14a, and the lower shaft part 22b engages with the locking claw 15 26 is formed.

According to the above-described clip structure, the female member 10
The body 11 has the mounting holes 2 of the member 2 to be mounted and the panel 3.
a, 3a to prevent it from falling off. During the insertion process,
The attachment claw 14a passes through the attachment hole while being reduced in diameter into the body with the insertion of the body 11 into the attachment hole, and when completely passed, is elastically restored and engaged with the hole edge of the attachment hole 3a. You. Thereafter, the male member 20 is pressed into the body 11 and the locking claw 1 is pressed.
5 is prevented from coming off by the engagement of the engaged portion 26. In the pressing process, the upper shaft portion 22a advances in the body while being in contact with the inner periphery of the body 11, and the engaged portion 26 engages with the locking claw 15 with a sense of moderation. The advantage of this structure is that the mounting claws 14a
When the female member 10 is mounted, the diameter of the mounting claw 14a is reduced to the inside of the body portion 11 when the male member 20 is pushed in. The pressing force can be kept small even if the output amount is increased and the fixing force to the panel side is increased. The male member 20 is
Since the engaged portion 26 is formed in the lower shaft portion 22b of the shaft portion 22, the insertion into the body portion 11 is more difficult than in the embodiment having the permanent retaining groove 69 in the middle of the shaft portion as shown in FIG. It is possible to provide the engaged portion 26 in a plurality of steps as described in claim 2 and the like.

The above invention is more preferably embodied as in claims 2 to 5. First, a plurality of the engaged portions 26 are formed at substantially equal intervals along the axial direction, and a portion at an appropriate position according to the thickness or the like of the attached member 2 is used as the engaging portion. It is configured to engage with the pawl 15. This has the advantage that, even if the members to be mounted 2 have different thicknesses, as shown in FIG. 5, they can be mounted on the panel 3 with the same fixed holding force, thereby providing versatility. Second, the engaged portion 26 is provided between the flanges 25 having an outer diameter substantially equal to the inner diameter of the body 11 and on the uppermost flange 25. This is because the versatility is realized by the simple structure of the flange 25 and the trunk 1
1 so that stable and strong engagement with the locking claw 15 can be obtained. Third, the mounting claw 14a is defined in the body 11 through a substantially U-shaped slit 16 and has a base end 14a.
b is provided on the free end side of the swinging piece 14 having a thickness smaller than the thickness of the body 11, and the mounting hole 3a of the panel 3 is provided with a diameter reduction into the body 11 through the swing of the base end 14b. It can be pushed into This is because even when the amount of protrusion of the mounting claw 14a is increased to increase the fixing force to the panel 3, the presence of the base end 14b in which the swinging piece 14 becomes thinner causes the body 11
It can be easily swung into the inside, so that it can be easily attached to the panel 3. Fourth, the male member 20 is connected to the inner diameter side of the flange portion 12 of the female member 10 via a small fragile portion 13,
The fragile portion 13 makes the mounting claw 14a the mounting hole 3 of the panel 3.
In this configuration, the cutting force is stronger than the pressing force at the time of press-fitting engagement with a, and can be cut with a pressing force slightly larger than the pressing force. This is not only because the female and male members 10 and 20 are integrally formed via the fragile portion 13, which is excellent in management and handling. Mounting hole 3a of panel 3 by pressing operation
At the same time, the mounting member 2 can be mounted on the panel 3 through the engagement between the engaged portion 26 and the locking claw 15 by the continuous pressing operation of the male member 20. In this case, since the male member 20 is connected to the inner diameter side of the female member 10 via the fragile portion 13, the male member 20 is reliably pushed into the body 11 along with the cutting of the fragile portion 13.

In the following description, the clip structure will be described in detail, and then use examples and operations will be referred to.

(Clip Structure) The clip 1 of the embodiment is
It is an injection-molded product made of plastic, in which a female member 10 and a male member 20 are integrally formed with a fragile portion 13 interposed therebetween.
Although enlarged in the drawing, the female member 1
0 is about 10 to 15 mm, male member 20 is 15 to 20 mm,
It is as small as about 25 mm to 30 mm in all dimensions. However, the size is appropriately changed.

The female member 10 has a rough outline formed by a cylindrical body 11 and a flange 12 protruding from the upper and outer periphery of the body 11. The body 11 has a pair of swinging pieces 14 provided around and facing each other, and a locking claw 15 provided inside the distal end. Each swinging piece 14 has a body 1
2, is defined by a substantially U-shaped slit 16 provided at the corresponding portion, and protrudes outward as approaching the flange portion 12 from below as shown in FIG. 14a. That is, the slit 16
Is located at the upper end side from the lower side than the upper and lower middle of the trunk 11,
The U-shaped intermediate piece approaches the flange 12 and the two pieces are arranged vertically. The rocking piece 14 is located in the slit 16, and the lower base end 14 b is formed to be thinner than the thickness of the body 11, so that the rocking piece 14 is easily rocked and displaced. The locking claw 15 is provided in a state in which the inside of the distal end located directly below the swinging piece 14 in the periphery of the distal end of the body 11 protrudes toward the inner diameter side. The locking claw 15 is provided with the vertical grooves 1 provided on both sides.
7, and can be slightly displaced by swinging through a body portion between the vertical grooves 17. The flange portion 12 has a slightly underfilled portion corresponding to the slit 16 and a body portion 11.
And an inner diameter or an inner diameter that is substantially continuous. A small piece-shaped fragile portion 13 protrudes from the inside diameter at a position dividing the periphery into three equal parts, and is connected to the male member 20 via the fragile portion 13. Reference numeral 18 denotes a hole or an opening.

The male member 20 has a head portion 21 and a shaft portion 22 inserted into the body portion 11. The head 21 is formed in a circular shape larger than the mounting hole 2 a of the mounted member 2.
The shaft portion 22 is a portion where the upper shaft portion 22a of the shaft portion inserted into the body portion 11 regulates the reduction of the diameter of the mounting claw 14a into the body portion 11, and the lower shaft portion 22b is the portion where the locking claw 15 And an engaged portion 26 that engages with the second member. The upper shaft portion 22a has a cross section of a substantially cross shape as shown in FIG. 3 (a), and is constituted by four regulating pieces 23 extending vertically in a state of projecting left, right, front and rear. As shown in FIG. 2, each restriction piece 23 includes a lower vertical portion 23 a having a lower portion, a taper portion 23 b having a diameter gradually increasing upward from the lower vertical portion 23 a, and an upper portion connected to the lower surface of the head 21. And a large-diameter vertical portion 23c. The large-diameter vertical portion 23c is a portion that regulates the inside diameter reduction of the mounting claw 14a. The small-diameter vertical portion 23a is connected to the lower shaft portion 22b. The lower shaft portion 22b has a plurality of flanges 25 provided in multiple stages along the vertical direction. Each flange 25 is formed in a circular shape having an outer diameter equal to or slightly smaller than the inner diameter of the body 11. The portion between the flange portions 25 is a small diameter portion corresponding to the flange diameter, and the small diameter portion becomes the engaged portion 26 to be engaged with the locking claw 15. In this embodiment, the flange 25 is 4
The locking claw 15 is a total of the three engaged portions 26 between the flange portions 25 and the engaged portion 26 that is a small-diameter portion on the uppermost flange portion 25. It is composed of four places. Note that the flange 25 may be provided with a slit in a part of a circle to facilitate elastic displacement. The lowermost side of the lower shaft portion 22b is a cylindrical connecting portion 22c having a smaller diameter than the flange portion 25. The connecting portion 22c is connected to the flange portion 12 of the female member 10.
Is inserted into the inner diameter of the housing with play, and the peripheral portion is connected to the fragile portion 13 described above. Therefore, the male member 20
Is erected on the center of the hole of the body 11 and the flange 12 while being connected and supported by the female member 10 via the fragile portion 13.

(Example of Use and Operation) FIGS. 4 and 5 show an operation procedure when the member to be mounted is mounted on the panel using the clip. The clip 1 in FIG.
The thickness of the base end 14b of the rocking piece 14 is the same as that of the body 11, but is substantially the same. In this example, the member to be mounted 2 is a ceiling trim material of a vehicle, a panel 3
Assumes a vehicle roof panel. However, in the present invention, the attached member 2 and the panel 3 may be other than this.
Further, the member to be mounted 2 is not limited to a single member such as a ceiling trim material, but may be a plurality of members. Attached member 2 and panel 3
May be in a mode in which members such as spacers are interposed between surfaces in contact with each other, or the like.

The member to be mounted 2 is placed on the panel 3 and positioned so that the mounting hole 2a coincides with the mounting hole 3a. From this state, the operator inserts the clip 1 into the mounting holes 2a, 3a as shown in FIG. In this case, for example, the head 21 of the male member 20 is picked, and the distal end of the female member 10 is attached to the mounting hole 2.
a, 3a and pressed in the direction of the arrow. Then, the female member 10 falls down until the rocking piece 14 hits the mounting hole 3a, and then the rocking piece 14 passes through the mounting hole 3a while reducing the diameter of the rocking piece 14 into the body portion 11 by the pressing force F1. The original shape is restored, and the mounting claw 14a engages with the edge of the mounting hole 3a as shown in FIG. In this engagement structure, the shaft 22
Is not inserted into the body 11 yet, and the diameter of the rocking piece 14 inward is not restricted. Therefore, even if the amount of protrusion of the mounting claw 14a is increased, it can be engaged with a relatively weak pressing force F1. On the other hand, although the female member 10 is attached to the panel 3 through the engagement between the attachment claw 14a and the attachment hole 3a, the fixing force is weak because the swinging piece 14 can be reduced in diameter into the body portion 11. However, in this mounting state, even when the mounting member 2 is under the panel 3 like a ceiling trim material and the clip 1 is in a suspended state, once the mounting claw 14a is engaged with the mounting hole 3a, Even if you release your hand, it will not accidentally come off the mounting hole 3a. Therefore, when a large number of clips 1 are used, it is also possible to perform the following fixing work after setting each of the clips 1 in the state shown in FIG. 4B.

The operator moves the male member 2 from the state shown in FIG.
When 0 is pressed with the pressing force F2, the fragile portion 13 is cut, and the cut causes the shaft portion 22 to fall into the body portion 11, whereby the lowermost flange portion 25 is regulated by the locking claw 15 as shown in FIG. You. The pressing force F2 here is a force for cutting the fragile portion 13, and is set to be larger than the above-described pressing force F1.
When the male member 20 is further pushed in the direction of the arrow from the state of FIG. 4C, the lowermost flange 25 as shown in FIG.
The locking claw 1 is oscillated and displaced like the flange 25 on it.
Go over 5 in order. The pressing force F3 is a force by which the flange 25 gets over the locking claw 15, and is set to be smaller than the pressing force F2. However, as the pressing force F3,
When the fixed holding force is further increased, it may be set to be larger than the pressing force F2. In any case, the operator can feel a click when the flange 25 goes over the locking claw 15. Then, when the head 21 comes into contact with the member 2 to be mounted, the mounting operation of the corresponding clip 1 is completed. FIG. 5A shows a state where the member to be attached 2 is attached to the panel 3 with the clip 1 in this manner.
In this example, the locking claw 15 is engaged with the engaged portion 26 on the uppermost flange 25.

By the way, the thickness of the attached member 2 depends on the target member and is T1 in FIG. 5 (a) and FIG. 5 (b).
As in the example of T2, the plate thickness may be partially different, such as T1 and T2, even for the same member. The above-described clip 1 can fix the attached member 2 to the panel 3 with the same fixed holding force even in such a case.
That is, in this structure, a plurality of engaged portions 26 are formed between the flange portions 25 provided in the upper and lower multi-stages, the upper diameter portion of the uppermost flange portion 25 and the lower diameter portion of the lowermost flange portion 25 are smaller. In addition, since the locking claw 15 is provided inside the distal end of the body portion 11 and is engaged with an arbitrary portion of the engaged portion 26, the locking claw 15 is affected by the thickness of the attached member 2. Thus, the fixed holding force of the clip 1 can be obtained, and the versatility is excellent. Further, in terms of versatility, if the flange portion 12 of the female member 10 is smaller than the mounting hole 2a of the mounted member 2, the female thickness is not affected by the plate thickness of the mounted member 2 as is apparent from FIG. Since the fixing force of the member 10 to the panel 3 and the engaging force of the engaged portion 26 and the engaging claw 15 can be always obtained at substantially the same level, the versatility of the invention can be improved in addition to the plurality of configurations of the engaged portion 26 described above. Can be more enhanced.

[0017]

As described above, in the clip of the present invention, when the female member is attached to the panel, the diameter of the mounting claw is reduced inside the body portion, and the diameter of the clip cannot be reduced into the body portion by pressing the male member. Therefore, the pressing force can be reduced even if the amount of protrusion of the mounting claw is increased and the fixing force to the panel side is increased, and the male member forms the engaged portion on the lower shaft portion of the shaft portion. As a result, the insertability into the body is excellent, and the engaged portion can be provided in a plurality of stages. Thereby, the product of the present invention has the advantages of the single member clip of FIG. 6 and the clip composed of the male and female members, and can further improve the handling, the mounting workability, the versatility, and the fixed holding force. .
