[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for an assist grip that supports a body by an occupant gripping the interior of an automobile.
[0002]
[Prior art]
As this type of conventional mounting structure, for example, there is one shown in JP-A-7-96790.
The conventional mounting structure is not specifically shown, but through holes are formed at both ends of the assist grip, bolts are inserted from the through holes, and the front ends of the bolts are nuts from the back side of the vehicle body panel. The assist grip is attached to the vehicle body panel by tightening with the bolt.
[0003]
[Problems to be solved by the invention]
For this reason, in the conventional mounting structure, not only the bolt, nut and assist grip must be managed separately, but also the problem that complicated bolt and nut turning work is required when installing the assist grip. Had a point.
[0004]
[Means for Solving the Problems]
The present invention was developed in order to effectively solve the problems of the conventional mounting structure, and the invention according to claim 1 is directed to a base member and a pin that support the assist grip so that the assist grip can swing. An attachment structure for attaching to a vehicle body panel via a member, wherein the base member is pivotally supported by an insertion hole portion into which the pin member is inserted, an elastic engagement leg portion to be engaged with the attachment hole of the vehicle body panel, and an assist grip. The pin member has a head portion and a shaft portion that is completely inserted into the insertion hole portion and restricts inward bending of the elastic locking leg portion, while the base member and the pin member are Between the pin member and the assist grip, there is provided a means for temporarily fixing both the members before completely inserting the shaft portion of the pin member into the insertion hole portion of the base member. Insertion into the insertion hole While blocking, it was adopted a structure that by pressing only the pin member into the fitting direction provided with means for fitting the shaft portion into the fitting hole.
[0005]
According to a second aspect of the present invention, on the premise of the first aspect, the contact portion of the pin member and the assist grip is substantially orthogonal to the insertion direction of the shaft portion of the pin member, or the head portion of the pin member As the pin is pressed, a configuration is adopted in which the pin member is inclined so as to float up in the direction opposite to the insertion direction of the shaft portion.
[0006]
The invention described in claim 3 is based on the premise of claims 1 and 2 and adopts a configuration in which the head of the pin member is elastically pressed against the assist grip by a spring.
[0007]
Therefore, in the invention according to the first aspect, since the assist grip is attached using the base member and the pin member instead of the bolt and nut, the attachment work is easier than the conventional one. In addition, since the base member and the pin member can be temporarily fixed, it is very convenient in terms of management and handling. In addition, in the temporarily fixed state of both members, the shaft portion of the pin member due to the swing of the assist grip Is prevented from being completely inserted into the insertion hole, and if the head of the pin member is pressed, it is not restrained by the assist grip. Thus, the shaft portion of the pin member can be completely inserted into the insertion hole portion, and the assist grip can be securely attached to the vehicle body panel side via the elastic locking leg portion.
[0008]
In addition to this, the contact portion of the pin member and the assist grip is substantially orthogonal to the insertion direction of the shaft portion of the pin member, or the pin member has its shaft portion. No matter how much the assist grip is rotated, the rotation is stopped and the insertion hole portion of the shaft portion of the pin member by the assist grip is inclined so as to float up in the direction opposite to the insertion direction of the pin. Therefore, the shaft portion of the pin member is never completely inserted into the insertion hole by mistake.
[0009]
In addition to this, the head of the pin member is covered with the assist grip because the head of the pin member is elastically pressed toward the assist grip by the spring. Therefore, the pin member can be prevented from falling off from the base member during conveyance and handling, and the shaft portion of the pin member can be prevented from being pushed into the insertion hole portion by colliding with another member.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail on the basis of a preferred embodiment shown in the drawings. The assist grip mounting structure according to the embodiment is different from the conventional one and supports the assist grip so that the assist grip can swing. It attaches to a vehicle body panel via the base member and pin member made from a synthetic resin.
[0011]
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 swung 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.
[0012]
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 for locking to the wall edge of the mounting hole of the vehicle body panel is formed on the wall surface through the slit 15, and the first lock hole 16 a and the second lock are formed in the vertical direction of the other opposing wall surface. When the hole 16b is formed and a pair of shaft support portions 17 are formed on the upper edge of the main body 12, and the shaft is supported by the corresponding recess 2 of the assist grip 1 via the shaft 32, one base member 11 is formed. A cylindrical damper 33 is mounted between the shaft support portions 17, and a torsion spring 31 is mounted between the shaft support portions 17 of the other base member 11.
[0013]
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. A pair of elastic pieces 26 are provided via a connecting portion 27, and a first dowel 28a and a second dowel 28b are integrally formed on an outer surface sandwiching the connecting portion 27 of the elastic piece 26.
[0014]
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 swing to the non-use position by providing the contact portion 3 that contacts the contact portion 3, the contact portion 3 is contacted with the side surface of the head 22 of the pin member 21, and the swing is performed. The shaft portion 23 of the pin member 21 is prevented from being automatically inserted into the insertion hole portion 13 by the swinging of the assist grip 1. Note that the same effect can be obtained even if the contact portion 3 is slightly inclined without being completely orthogonal to the insertion direction.
[0015]
Therefore, when the assist grip 1 is attached to the vehicle body panel P using such a base member 11 and the pin member 21, the shaft portion 23 of the pin member 21 together with the elastic piece 26 is attached to the base as shown in FIG. When inserted into the insertion hole 13 of the member 11, each of the second dowels 28 b formed on the elastic piece 26 of the pin member 21 obtains the deflection 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, the pin member 21 is formed at both ends of the assist grip 1 as shown in FIG. The base member 11 is pivotally supported by the recessed portion 2 through the pivot 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. Further, the head 22 of the pin member 21 to which the torsion spring 31 is attached is elastically pressed by the torsion spring 31 toward the concave portion 2 of the assist grip 1, so that the head 22 of the pin member 21 is supported by the assist grip 1. The pin member 21 can be prevented from falling off from the base member 11 during conveyance and handling, and the shaft portion 23 of the pin member 21 can be brought into the insertion hole portion 13 by colliding with another member. It can also be prevented from being pushed in.
[0016]
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 swings in the biased direction. Since this is stopped, the pin member 21 is prevented from being completely inserted into the insertion hole 13.
[0017]
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 from the first lock hole 16a on the base member 11 side by obtaining the deflection of the elastic piece 26, and this second dowel 28b is now second 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 without coming off, and at the same time as shown in FIG. The restriction wall 25 of the pin member 21 is positioned on the back side of the pair of elastic locking legs 14 to prevent the elastic locking legs 14 from bending inward, so that the base member 11 is mounted on the vehicle body panel P. Assist grip 1 is final because it is firmly fixed to the side And thus attached to the vehicle body panel P side.
[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 fitted into the fitting hole portion 13 of the base member 11, and the roof lining 34 and the assist grip 1 are joined 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 swing to the non-use position, the swing is stopped, and the shaft portion 23 of the pin member 21 can be prevented from being automatically inserted into the insertion hole portion 13. Is possible.
[0020]
In these cases, the abutment portion 3 abuts against the head portion 22 of the pin member 21 in a state substantially orthogonal to the insertion direction of the shaft portion 23 of the pin member 21 with respect to the insertion hole portion 13, and the assist grip 1 is attached. On the contrary, 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 as shown in FIG. Similarly, the pin member 21 can be lifted from the base member 11 at the inclination angles of the respective tapered shapes, and similarly, the swing of the assist grip 1 in the urging direction can be stopped. In this case, even if the pin member 21 is lifted, the head portion 22 collides with the wall surface on the opposite side of the contact portion 3 and stops, so that the pin member 21 does not fall off.
[0021]
【The invention's effect】
As described above, according to the present invention, by adopting the above configuration, the assist grip is attached using the base member and the pin member instead of the bolt and nut, so that the attachment work is easier than the conventional one. In addition, since the base member and the pin member can be temporarily fixed, it is very convenient in terms of management and handling. In addition, in the temporarily fixed state of both members, the shaft portion of the pin member due to the swing of the assist grip Is prevented from being completely inserted into the insertion hole, and if the head of the pin member is pressed, it is not restrained by the assist grip. Thus, the shaft portion of the pin member can be completely inserted into the insertion hole portion, and the assist grip can be securely attached to the vehicle body panel side via the elastic locking leg portion.
