DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door trim mounted on the interior side of an automobile door.

[0002]

2. Description of the Related Art Conventional door trims for automobiles include, for example, Japanese Utility Model Laid-Open No. 01-165726 or Japanese Utility Model Laid-Open No. 02-6.
No. 8063 or Japanese Utility Model Laid-Open No. 03-110911.

[0003] The technology disclosed in these publications discloses a trim main body having an armrest portion which covers an inner panel constituting a door from the vehicle interior side and protrudes into the vehicle interior side and has a flat upper surface, and an armrest of the trim main body. It is at least constituted by a pull handle member which is inserted through an opening formed in the upper surface of the unit and which is turned by hand and pulled to close the door. The pull handle member is arranged on the trim main body by screwing a screw for inserting a through hole formed in the bottom of the pull handle member into a nut of a bracket fixed to an inner panel of a door or the like. Be done.

[0004]

However, in order to screw the screw into the nut of the bracket as described above, the tip of the screw is not visible at the bottom of the pull handle member. To engage the hole,
So-called blind work is performed depending on intuition, and improvement in workability is desired.

In addition, if the size of the opening for inserting the pull handle member of the trim main body is increased to reduce the cost of the manufacturing process, the pull handle member can be freely moved back and forth and left and right within the insertion opening. This makes it difficult for the position of the through hole for the screw of the pull handle member to be inserted to match the position of the prepared hole of the bracket nut, which may cause a rise in cost in terms of the number of man-hours required for installation, and improves workability. Is desired.

Further, when a rotational force caused by the screwing of the screw is applied to the pull handle member, the force acts on the opening for inserting the pull handle member of the trim main body, thereby deforming the shape of the opening or removing the fiber material. Repair work such as pulling may be required.

Accordingly, an object of the present invention is to provide an automobile door trim which remarkably improves the workability of attaching a pull handle member to a door and reduces the horizontal rotational force applied to the pull handle member and transmits it to a trim main body. And

[0008]

According to a first aspect of the present invention, there is provided a trim main body having an armrest portion which covers an inner panel constituting a door from a vehicle interior side and projects to the vehicle interior side. And a bottomed substantially cylindrical pull handle member inserted through an opening formed on an upper surface of an armrest portion of the trim main body, the door trim for an automobile comprising at least a bottom portion of the pull handle member. Is formed with a screwing portion for screwing and supporting the door, and in the vicinity of the screwing portion, can prevent the horizontal rotation of the pull handle member and guide the holding position of the pull handle member. And a guide means that can be provided.

According to a second aspect of the present invention, there is provided an automobile door trim according to the first aspect, wherein the guide means is fixed to a rib formed on a bottom portion of the pull handle member and the door. And a slit having a dimension as small as possible with a gap formed when the rib is inserted.

According to a third aspect of the present invention, there is provided the door trim for an automobile according to the second aspect, wherein a chamfered portion is formed at an opening of the slit so as to guide a tip portion of the rib into the slit. It is characterized by becoming.

According to a fourth aspect of the present invention, there is provided the door trim for an automobile according to the second or third aspect, wherein the bracket is formed with a pilot hole of the screw portion and the slit. It is characterized by.

According to a fifth aspect of the present invention, there is provided the door trim for an automobile according to the second or third aspect, wherein the screw portion is formed at one position on a bottom portion of the pull handle member. The rib is located on the front side of the threaded portion.

[0013]

As is clear from the above, according to the first aspect of the present invention, even if a horizontal rotational force is applied to the pull handle member by the guide means, the rotational force can be eliminated. The transmission of the rotational force to the trim main body can be reduced. Further, by guiding the holding position of the pull handle member by the guide means, the workability of attaching the pull handle member to the door can be remarkably improved despite the blind work.

According to the second aspect of the present invention, the rib formed on the bottom of the pull handle member is inserted into the slit formed on the bracket fixed to the door, and is inserted into the slit. Since the gap between the slit and the slit is formed as small as possible, even if a horizontal rotational force is applied by the pull handle member, the position of the rib formed integrally with the pull handle member is reduced. It does not move and the rotational force is eliminated, so that the trim main body and the like are not affected.

According to the third aspect of the present invention, even if the opening of the trim main body is large and it is difficult for the through hole of the pull handle member to match the pilot hole of the bracket, the trim of the pull handle member may be used. If it moves to a large extent, it will hit the chamfer of the opening of the slit, so it is extremely easy to insert the rib into the slit along the chamfer,
After inserting the rib into the slit, the position is the matching position of the through hole of the pull handle member and the prepared hole of the bracket, so if you insert the screwing tool into the through hole, it will match the screwing position as it is Therefore, the mounting operation becomes remarkably easy.

According to the fourth aspect of the present invention, since the pilot hole of the threaded portion and the slit are integrally formed in the bracket itself capable of determining the position of the pull handle member, the dimensional tolerance is also increased. Since it can be performed in the bracket, dimensional deviation is hardly caused.

According to the fifth aspect of the present invention, the input to rotate the pull handle member in the horizontal direction at the time of the door closing operation can be dispersed.

The lower hole 1 is formed by a U-shaped portion 13a which is sandwiched and fixed.
The nut 13 is supported on the same axis as the screw 2. A screw 14 is screwed into the nut 13 through the pilot hole 12,
The pull handle member 3 is fixed to the bracket 8.

The trim main body 2 is composed of a wood core material (a wood chip hardened with a synthetic resin) 2a and a surface material 2b made of polyvinyl chloride which covers the surface.
This is a cloth-made decorative member which is pressed and supported in the concave groove 21 of the trim main body 2. The lower trim 16 is a PP
It is made of C (filler-filled polypropylene) synthetic resin.

The operation of the above-described door trim 1 will be described below.

First, the door trim 1 in which the trim main body 2 and the lower trim 16 are integrally joined is fixed to the inner panel INR of the door by appropriate means, and then the pull handle member 3 is attached. At this time, the screw 14 is connected to the nut 1 by the rib 7 and the slit 9 of the pull handle member 3.
Even if a horizontal rotational force (arrow B in FIG. 2) due to screwing is applied to the pull handle member 3, the rotational force can be eliminated, so that the rotational force of the screw 14 is transmitted to the trim main body 2. There will be no. For this reason, the opening 4a for inserting the pull handle member 3 of the trim main body 2 is not pressed in the horizontal direction, and the shape of the opening 4a is not deformed, so that a repair work is not required.

That is, when the rib 7 formed on the bottom 5 of the pull handle member 3 is inserted into the slit 9 of the bracket 8 formed on the lower trim 16, the rib 7 is inserted between the rib 7 and the slit 9. Are formed as small as possible, so that even if a horizontal rotational force (arrow B in FIG. 2) is applied by the pull handle member 3,
The front and rear surfaces of the pull handle member 3 and the front and rear surfaces of the slit 9 come into contact with each other, so that the rib 7 formed integrally with the pull handle member 3
Does not move, the rotational force is eliminated, and the trim main body 2 and the like are not affected.

The rib 7 and the slit 9 as guide means allow the pull handle member 3 to be held by simply inserting the rib 7 into the slit 9 as shown by an arrow C in FIG. Can be guided,
In spite of the blind work, the workability of attaching the pull handle member 3 to the door can be significantly improved.

The pull handle member 3 of the trim body 2
Even if the size of the opening for insertion is increased to reduce the cost of the manufacturing process, the position of the through hole 12 for inserting the screw 14 of the pull handle member 3 and the position of the nut 13 of the bracket 8 can be easily matched. The cost can be reduced in terms of man-hours for mounting work.

A door hinge (not shown) is located on the front side FR of the door, and the center of rotation O of the door is located on the front side FR of the vehicle.
When the door is closed, the input in the direction of arrow D in FIG. 3 tends to act on the front FR portion of the vehicle on the pull handle member 3 fixed to the screw 14 on the bracket 8 at one location on the bottom 5. However, since the surface of the rib 7 on the vehicle interior RM side and the surface of the slit 9 on the exterior OS side are engaged to disperse the input to rotate the pull handle member 3 in the horizontal direction, Like the above, the trim main body 2 and the like are not affected.

Even if the opening 4a of the trim main body 2 is larger than the size of the pull handle member 3 and the through hole 6 of the pull handle member 3 and the pilot hole 12 of the bracket 8 are difficult to match, When the rib 7 of the handle member 3 is moved to a certain extent, the chamfered portion 1 of the opening 10 of the slit 9 is moved.
It is extremely easy to insert the ribs 7 into the slits 9 along the chamfers 11, 11 because the bumps 1 and 11 are hit.
Since that position is the position where the through hole 6 of the pull handle member 3 and the prepared hole 12 of the bracket 8 match, if the screw 14 which is a “screw tool” is inserted into the through hole 6, it is the screwed position as it is. Since the holes are aligned with the central axes of the pilot hole 12 and the nut 13, the mounting operation is remarkably easy.

A screw 1 is provided on the upper surface 8a of the bracket 8 on which the position of the pull handle member 3 can be determined.
Since the pilot hole 12 and the slit 9 are integrally formed, the dimensional tolerance can be made in the bracket 8, so that the dimensional deviation hardly occurs.

Further, in the above-described embodiment, the rib 7 is provided on the front side FR of the vehicle with respect to the through hole 6. However, as shown by the dotted lines in FIGS. Similarly, a rib 7 'may be provided on the rear side RR. In this case, the pull handle member 3 can be shared on the left and right sides of the vehicle. At this time, the side wall 8 of the bracket 8 on the vehicle rear side RR
The position of the pull handle member 3 is such that the side wall 8c of the vehicle rear side RR and the rib 7 'do not engage with each other by positioning the c on the vehicle front side FR with respect to the rib 7' on the vehicle rear side RR. This is desirable for mounting work or for positioning the front reference.
