Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved attachment structure for an assistant grip that facilitates attachment.

[0002]

2. Description of the Related Art As shown in FIG. 9, an assistant grip 100 for an occupant is mounted on the interior ceiling of a vehicle. This assistant grip 100 is provided with mounting portions 102 curved in an arc shape on both sides of a grip portion 101. A screw 104 is inserted into a mounting hole 103 provided in the mounting portion 102 and is screwed to a ceiling portion 105. There is.
To screw the assistant grip 100 to the ceiling portion 105, the screw 104 is inserted into the mounting hole 103, is positioned on the ceiling portion 105, and the screw 104 is screwed.

[0003]

However, as shown in FIG. 10, the mounting hole 103 is different from the mounting hole 106 provided in the ceiling 105 in terms of the hole pitch L.
The diameter is formed large in consideration of the deviation from 06. For this reason, as shown in FIG.
There is a possibility that the screw 104 may rattle and the screw 104 may fall off during the assembling work with the screw 104 inserted in the mounting hole 103, as shown in the arrow of FIG. So, conventionally,
As shown in FIG. 12, the paper washer 1 is attached to the shaft of the screw 104.
No. 07 is attached, and the paper washer 107 is engaged with the end surface of the assistant grip 100, so that the screw 1
We are trying to prevent 04 from falling out.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide an attachment structure for an assistant grip which can prevent a screw from falling off.

[0005]

In order to solve the above problems, the present invention provides an assistant grip mounting structure in which a screw is inserted through the mounting holes formed at both ends and screwed to a wall surface. There is a thin rib that projects inward.

Further, according to the present invention, there is provided a rib in a direction substantially orthogonal to a line connecting the mounting holes.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

1 to 5, a vehicle body 1 of an automobile
On the right and left sides of the indoor ceiling portion 2, arc-shaped assistant grips 3 are attached.

The assistant grip 3 has a central grip portion 3a and mounting portions 3b provided on both sides of the grip portion 3a.
And mounting holes 5 for screwing to the ceiling 2 with screws 4 are formed in the mounting portions 3b. The mounting hole 5 is formed of a large diameter portion 5a for locking the head 4a of the screw 4 and a small diameter portion 5b for inserting the shaft portion 4b of the screw 4. As shown in FIG. 5, the small-diameter portion 5b of the mounting hole 5 has a pair of ribs 6 on the tip side thereof in a direction substantially orthogonal to the line connecting the mounting holes 5 and toward the central axis. Is projected. Since the ribs 6 are provided in a direction substantially orthogonal to the hole pitch of the mounting holes 5, the screw 4 can be moved in the direction of the hole pitch to absorb an error in the mounting position on the ceiling portion 2 side. it can. Rib 6 above
Is a thin-walled tongue-shaped member integrally formed with the assistant grip 3. The distance m between the ribs 6 is, as shown in FIGS.
It is formed to be smaller than the diameter n of b (m <n), and the shaft portion 4b of the screw 4 is held between these ribs 6.

Next, the assistant grip 3 having the above structure.
The procedure for attaching the camera to the ceiling 2 will be described. First, the screw 4 is inserted into the attachment hole 5 of the assistant grip 3, and the shaft portion 4b of the screw 4 is held by the rib 6 of the small diameter portion 5b of the attachment hole 5. Then, the assistant grip 3 is arranged on the ceiling part 2, and the screw 4 is screwed into the nut 7 provided on the back surface side of the ceiling part 2 to fix the assistant grip 3 to the wall surface 2 a of the ceiling part 2. In this way, assistant grip 3
Since the screw 4 is prevented from falling off from the mounting hole 5, the workability of mounting the assistant grip 3 can be improved.

Ribs 6 provided on the small diameter portion 5b of the mounting hole 5.
As shown in FIG. 7, by tightening the screw 4, the space between the wall surface 2a of the ceiling portion 2 and the screw 4 is crushed and deformed, and is accommodated in the small diameter portion 5b.

The rib 6 may be provided at the base end portion of the small diameter portion 5b of the mounting hole 5, as shown in FIG.

According to the above embodiment, the rib 6 prevents the screw 4 from falling off, so that the assistant grip 3
Can be easily mounted. Further, since the rib 6 is integrally formed with the assistant grip 3, the cost and man-hours are not increased. Since the rib 6 enters into the screw thread of the screw 4 and is locked, the screw 4 can be securely temporarily fixed. Furthermore, since the rib 6 holds the shaft portion 4b of the screw 4 by bending toward the tip side of the small diameter portion 5b of the mounting hole 5, no force acts in the direction in which the screw 4 is removed. Therefore, the screw 4 can be reliably held.
Since the ribs 6 are provided in a direction substantially orthogonal to the line connecting the mounting holes 5, that is, in a direction orthogonal to the hole pitch, even when the position of the ceiling portion 2 is displaced from the mounting holes. The shaft portion 4b of the screw 4 can be held.

[0014]

As described above, according to the assistant grip mounting structure of the present invention, the following effects can be obtained.

In the first aspect of the present invention, in the attachment structure of the assistant grip in which screws are inserted into the attachment holes formed at both ends and screwed to the wall surface, the attachment holes are provided with thin ribs protruding inward. Therefore, there is no risk that the screws will fall off during the installation work of the assistant grip. In the second aspect, since the ribs are provided in the direction substantially orthogonal to the line connecting the mounting holes, the position of the screw can be adjusted in the hole pitch direction of the mounting holes.
