Although the assist grip 1 can swing between the non-use position and the use position by rotatably supporting the first shaft support 17 via the shaft 32, the assist grip 1 has a torsion. With the spring pressure of the spring 31,
It is always urged toward the unused position. 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
It refers to the position where it turns from the unused position and projects toward the room.

As shown in FIG. 2, the base member 11 defines an insertion hole 13 into which a shaft 23 of a pin member 21 described later is inserted.
A pair of elastic locking legs 14 are formed on one of the opposing wall surfaces of the lower part through slits 15 to be engaged with the rims of the mounting holes of the vehicle body panel, and a first lock is formed on the other opposing wall surface in the vertical direction. Forming a hole 16a and a second lock hole 16b, and
When a pair of shaft supports 17 are formed on the upper edge of the main body 12 and are supported by the corresponding concave portion 2 of the assist grip 1 via the shaft 32, a cylinder is provided between the shaft supports 17 of one base member 11. A torsion spring 31 is mounted between the shaft supports 17 of the other base member 11.

As shown in FIG. 3, the pin member 21 has a head portion 22 and a shaft portion 23. Particularly, the shaft portion 23 is fitted into the fitting holes 13 of the base member 11 on both sides thereof. And a pair of regulating walls 25 for regulating the inward bending of the pair of elastic locking legs 14 inside the guide rib 24, and a head 22 on the outside of the guide rib 24. A pair of elastic pieces 26 hanging down from the lower surface
The first dowel 28a and the second dowel 28b are integrally formed on the outer surface of the elastic piece 26 with the connecting portion 27 interposed therebetween.

Further, as shown in FIG. 4, the recessed portion 2 of the assist grip 1 is set in a state perpendicular to the fitting direction of the shaft portion 23 of the pin member 21 into the fitting hole 13.
When the assist grip 1 attempts to swing to the non-use position by providing the contact portion 3 which contacts the side surface of the head member 22 of the pin member 21, the contact portion 3 contacts the side surface of the head member 22 of the pin member 21. Upon contact, the swing is stopped, and the swing of the assist grip 1 prevents the shaft portion 23 of the pin member 21 from automatically fitting into the fitting hole 13. The same effect can be obtained even if the contact part 3 is not completely perpendicular to the fitting direction but is slightly inclined.

Therefore, when the assist grip 1 is mounted on the vehicle body panel P using the base member 11 and the pin member 21, the shaft 23 of the pin member 21 is connected to the elastic piece 26 as shown in FIG. When they are fitted together into the fitting holes 13 of the base member 11, each of the second dowels 28 b formed on the elastic piece 26 of the pin member 21 obtains the bending of the elastic piece 26 and forms on the wall surface of the base member 11. The first lock hole 16a is engaged with the
After such a state is obtained, the base member 11 can be rotated via the shaft supporting portions 17 into the concave portions 2 formed at both ends of the assist grip 1 after obtaining such a state, as shown in FIG. To support. In this case, as described above, the cylindrical damper 3 is provided between the shaft support portions 17 of the one base member 11.
3 is mounted, and a torsion spring 31 is mounted between the shaft supports 17 of the other base member 11. or,
The head 22 of the pin member 21 on which the torsion spring 31 is mounted is elastically pressed by the torsion spring 31 toward the recess 2 of the assist grip 1, so that the head 22 of the pin member 21 is covered by the assist grip 1. As a result, the pin member 21 can be prevented from falling off from the base member 11 during transportation or handling, and the shaft portion 23 of the pin member 21 is pushed into the fitting hole portion 13 while colliding with another. Can also be prevented.

Then, this time, the center portion of the assist grip 1 is gripped, and the main body 12 of each base member 11 which is pivotally supported at both ends is attached to the vehicle body panel P from the front end thereof. 7, the pair of elastic locking legs 14 are bent inward on each side to pass through the mounting hole H, and then elastically locked to the edge of the mounting hole H, as shown in FIG. 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 of the assist grip 1 contacts the side of the head 22 of the pin member 21 temporarily fixed to the base member 11 and swings in the biased direction. Is stopped, the pin member 21 is prevented from being completely fitted into the fitting hole 13.

Therefore, finally, the head 22 of the pin member 21

The restriction wall 25 of the pin member 21 is located on the back side of the fourth member 4 to prevent the elastic locking leg 14 from bending inward.
Since the base member 11 is firmly fixed to the vehicle body panel P side, the assist grip 1 is finally attached to the vehicle body panel P side.

In the above-described embodiment, the roof lining 34 is fixed to the vehicle body panel P in advance, and the assist grip 1 is attached via the base member 11 and the pin member 21 later. However, 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 installed on the roof lining 34 side. The base member 11 is locked in 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 13 of the base member 11, and the roof lining 34, the assist grip 1, May be optionally attached to the vehicle body panel P depending on the implementation.

The contact portion 3 formed on the side of the concave portion 2 of the assist grip 1 is not limited to the one described above. For example, as shown in FIG. As shown in FIG. 2B, the groove 2 is formed on the side of the head 22 of the pin member 21.

When it is attempted to swing to the non-use position, the swing can be stopped to prevent the shaft portion 23 of the pin member 21 from automatically fitting into the fitting hole portion 13. It is.

In these cases, the shaft 2 of the pin member 21
The contact portion 3 comes into contact with the head portion 22 of the pin member 21 in a state that is substantially perpendicular to the direction in which the assist grip 1 is inserted into the insertion hole portion 13, thereby stopping the swing of the assist grip 1 in the biasing direction. Conversely, as shown in FIG. 13, a downward tapered shape is given to the side surface of the head 22 of the pin member 21 and an upward tapered shape is given to the contact portion 3 so that the pin member is inclined at an inclination angle of each taper shape. Similarly, it is possible to stop the swing of the assist grip 1 in the biasing direction by causing the base 21 to float from the base member 11. In this case, even if the pin member 21 rises, the head member 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]

As described above, according to the present invention, the assist grip is mounted by using the base member and the pin member instead of the bolt and the nut by adopting the above configuration. The mounting work becomes easy, and the base member and the pin member can be temporarily fixed, which makes it very convenient for management and handling. Since the insertion of the shaft of the pin member into the insertion hole is prevented, the shaft of the pin member is prevented from being completely inserted into the insertion hole by mistake, and if the head of the pin member is pressed, the assist is provided.
