Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a two-piece clip that is used when, for example, an automobile equipment is attached to a vehicle body panel.
[0002]
[Prior art]
A conventional two-piece clip of this kind is shown in US Pat. No. 5,560,575.
The conventional two-piece clip was developed for the purpose of attaching a coat hook, which is a car equipment, to a vehicle body panel. The base member is integrally provided with a base member fixed to the vehicle body panel and a coat hook body. The former base member is a convex member that is elastically engaged with an elastic locking leg portion that is locked to a mounting hole of the vehicle body panel and a concave portion of the pin member that will be described later. The latter pin member has a shaft portion inserted into the insertion hole portion of the base member, and a first concave portion and a second concave portion that engage with the convex portion of the base member with a certain interval. It has the composition which has.
[0003]
When using this two-piece clip to attach the coat hook to the vehicle body panel side, first, when the shaft part of the pin member is inserted into the insertion hole part of the base member, the convex part on the base member side is on the pin member side. Since both members are temporarily fixed by engaging with the first recess, the elastic locking leg portion of the base member is then locked in the mounting hole formed in the vehicle body panel in this temporarily fixed state. Then, after fixing the base member to the vehicle body panel side, if the shaft portion of the pin member is completely inserted into the insertion hole portion of the base member, then the convex portion on the base member side is now the second concave portion on the pin member side. Since the pin member is permanently fixed to the base member, the coat hook is attached to the vehicle body panel side.
[0004]
[Problems to be solved by the invention]
For this reason, in the conventional two-piece clip, it is possible to attach the coat hook to the vehicle body panel side using the temporarily fixed state and the final fixed state of the base member and the pin member. Since the engagement force between the both members in the temporarily fixed state and the final fixed state is the same, if the engagement force between the concave portion and the convex portion is reduced, the insertion work to the insertion hole portion of the base member of the shaft portion of the pin member is performed. On the other hand, the engagement force between the pin member and the base member in the fully-fastened state also decreases, the pin member comes out of the base member, and the coat hook mounting state becomes unstable. If the engaging force of the convex portion is increased, the engaging force will not be insufficient, so that the pin member is prevented from coming out of the base member, and the coat hook mounting state is stabilized. , There was a dislike fitted operation for fitting hole portion of the base member of the shaft portion of the pin member is difficult.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to a preferred embodiment. A two-piece clip according to the embodiment includes a base member made of a synthetic resin and a pin member. It is characterized by being attached to a vehicle body panel.
[0010]
Specifically, as shown in FIG. 1, first, recesses 2 for accommodating the base member 11 together with the pin member 21 are formed at both ends of the assist grip 1. A support portion 17 of the base member 11 to be described later is pivotally supported in the recess 2 via a shaft 32 so that the assist grip 1 can be rotated between a non-use position and a use position. The assist grip 1 is always elastically biased toward the non-use position by the spring pressure of the torsion spring 31. Here, the non-use position of the assist grip 1 is a parallel position along the wall surface of the automobile, and the use position is a position that is rotated from the non-use position and protrudes in the indoor direction.
[0011]
Further, as shown in FIG. 2, the base member 11 defines a fitting hole portion 13 into which a shaft portion 23 of the pin member 21 described later is fitted inside the main body 12, and is opposed to a lower portion of the main body 12. A pair of elastic locking legs 14 that are locked to the wall edge of the mounting hole of the vehicle body panel are formed on the wall surface through the slit 15 and communicated with the fitting hole 13 in the vertical direction of the other opposing wall surface. The lock hole 16a and the second lock hole 16b are formed at regular intervals, and a pair of shaft support portions 17 are formed on the upper edge of the main body 12, and the shaft 32 is provided in the corresponding recess 2 of the assist grip 1. When the shaft member is pivotally supported, a cylindrical damper 33 is mounted between the shaft support portions 17 of one base member 11, and a torsion spring 31 is mounted between the shaft support portions 17 of the other base member 11. Yes.
[0012]
As shown in FIG. 3, the pin member 21 has a head portion 22 and a shaft portion 23, and in particular, with respect to the shaft portion 23, guide ribs for fitting into the fitting hole portions 13 of the base member 11 on both sides thereof. 24, and a pair of restriction walls 25 for restricting inward bending of the pair of elastic locking legs 14 are provided inside the guide rib 24, and the guide rib 24 is suspended from the lower surface of the head 22 outside the guide rib 24. The first dowels 28a and the second dowels 28b are formed on the outer surface sandwiching the connecting portions 27 of the respective elastic pieces 26 at regular intervals. It has a configuration.
[0013]
Further, as shown in FIG. 4, the recess 2 of the assist grip 1 has a state perpendicular to the insertion direction of the shaft portion 23 of the pin member 21 with respect to the insertion hole portion 13, and the side surface of the head portion 22 of the pin member 21. When the assist grip 1 tries to rotate to the non-use position by providing the abutting portion 3 that abuts on the head, the abutting portion 3 abuts against the side surface of the head 22 of the pin member 21 and rotates. The shaft portion 23 of the pin member 21 is prevented from being automatically inserted into the insertion hole portion 13 by the rotation of the assist grip 1.
[0014]
Therefore, when the assist grip 1 is attached to the vehicle body panel P using the base member 11 and the pin member 21, the shaft portion 23 of the pin member 21 is attached together with the pair of elastic pieces 26 as shown in FIG. When the base member 11 is inserted into the insertion hole 13, each of the second dowels 28 b formed on the elastic piece 26 of the pin member 21 obtains bending of the elastic piece 26 and is formed on the wall surface of the base member 11. Since the pin member 21 is temporarily fixed to the base member 11 by engaging with the first lock hole 16a with a light force, both ends of the assist grip 1 are obtained as shown in FIG. The base member 11 is pivotally supported by the concave portion 2 formed in the portion via the pivotal support portion 17 so as to be rotatable. In this case, as described above, the cylindrical damper 33 is mounted between the shaft support portions 17 of the one base member 11, and the torsion spring 31 is mounted between the shaft support portions 17 of the other base member 11. Shall.
[0015]
Then, this time, the center portion of the assist grip 1 is gripped, and the main body 12 of each base member 11 pivotally supported at both ends is pushed into the mounting hole H formed in the vehicle body panel P from the front end side. And, as shown in FIG. 7, on each side, the pair of elastic locking legs 14 bend inward and pass through the mounting hole H, and then elastically lock to the hole edge of the mounting hole H. As a result, the assist grip 1 is temporarily attached to the vehicle body panel P. In this temporarily attached state, the contact portion 3 on the assist grip 1 side contacts the side surface of the head 22 of the pin member 21 temporarily fixed to the base member 11 and rotates in the biased direction. Therefore, the pin member 21 is prevented from being completely inserted into the insertion hole 13 by mistake.
[0016]
Therefore, finally, when the head portion 22 of the pin member 21 is pressed with a finger and the shaft portion 23 is completely inserted into the insertion hole portion 13, the elastic member 26 on the pin member 21 side is formed as shown in FIG. Each of the second dowels 28b is bent by the elastic piece 26 and is disengaged from the first lock hole 16a on the base member 11 side. As shown in FIG. While engaging with the lock hole 16b, the first dowel 28a is engaged with the first lock hole 16a, and the pin member 21 and the base member 11 are finally fixed. As shown in FIG. The restriction wall 25 of the pin member 21 is positioned on the back surface side of the locking leg portion 14 to prevent the elastic locking leg portion 14 from being bent inward, so that the base member 11 is firmly attached to the vehicle body panel P side. Since it is fixed, the assist grip 1 is finally on the body panel P side. And thus attached.
[0017]
In addition, when the both members 11 and 21 are in the fully-fastened state, the two dowels 28a and 28b are engaged with the corresponding lock holes 16a and 16b at two locations, so that both the members 11 and 21 are connected. When removing, it is necessary to bend the two dowels 28a and 28b at the same time with a large force, and as a result of this strong engagement force, a reliable full stop state of both members 11 and 21 can be obtained. The attached state of the grip 1 is also stable. However, in order to obtain a temporarily fixed state, only one second dowel 28b is obtained by bending the elastic piece 26 and engaged with the first lock hole 16a. Therefore, the fitting operation can be performed with a small force.
[0018]
In the embodiment described above, the roof lining 34 is fixed to the vehicle body panel P side in advance, and the assist grip 1 is attached later via the base member 11 and the pin member 21. As shown in FIG. 11, a claw 18 for temporarily fixing the roof lining 34 is provided on the outer peripheral surface of the main body 12 of the base member 11, and the assist grip 1 is first assembled on the roof lining 34 side. Is engaged with the mounting hole H of the vehicle body panel P, and finally the shaft portion 23 of the pin member 21 is completely inserted into the insertion hole portion 13 of the base member 11 so that the roof lining 34 and the assist grip 1 are brought together. It is optional depending on the implementation to be mounted on the vehicle body panel P.
[0019]
Further, the contact portion 3 formed on the concave portion 2 side of the assist grip 1 is not limited to the above-described one, and for example, as shown in FIG. As shown in FIG. 5B, a concave groove 29 is formed on the side surface of the head portion 22 of the pin member 21, and the protruding contact portion 3 is inserted into the concave groove 29. As shown in FIG. 3C, a through hole 30 is formed in the head portion 22 of the pin member 21, and the abutting portion 3 is inserted into the through hole 30 to assist the grip. When 1 tries to rotate to a non-use position, it can also be set as the structure which stops the rotation and prevents that the axial part 23 of the pin member 21 fits into the insertion hole part 13 automatically. It is.
[0020]
In these cases, the abutment portion 3 abuts against the side surface of the head portion 22 of the pin member 21 in a state orthogonal to the insertion direction of the shaft portion 23 of the pin member 21 with respect to the insertion hole portion 13. However, conversely, as shown in FIG. 13, a downward taper shape is applied to the side surface of the head portion 22 of the pin member 21 and an upward taper shape is applied to the contact portion 3. Thus, the rotation of the assist grip 1 with respect to the urging direction can be similarly stopped by causing the pin member 21 to rise from the base member 11 at the inclination angles of the respective tapered shapes.
[0021]
【The invention's effect】
As described above, according to the present invention, by adopting the above configuration, when the shaft portion of the pin member is fitted together with the elastic piece in the fitting hole portion of the base member, the elastic piece is bent and the first lock on the base member side is obtained. The second dowel on the pin member side is engaged with the hole, and the base member and the pin member are temporarily fixed. Therefore, the temporary fixing operation can be easily performed, while the shaft portion of the pin member is attached to the insertion hole portion of the base member. When it is further inserted, the second dowel on the pin member side is engaged with the second lock hole on the base member side, and at the same time, the first dowel on the pin member side is engaged with the first lock hole on the base member side. Thus, the base member and the pin member are finally fixed with a large engagement force.
