Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a resin flange formed on a resin member for attaching the resin member to an immovable portion.

(Prior Art) Conventionally, when attaching a resin member to an immovable portion, a flange is often formed on the resin member and the resin member is attached to the immovable portion via the flange.

An under cover of an automobile is known as a resin member that is attached to the non-moving part via this flange. As shown in FIG. 4, the under cover is arranged substantially below a glove box 3 provided in a lower portion of an instrument panel 1 in front of a passenger seat of a vehicle, and on the side thereof, a lower portion of a center console 2 is provided. The backbone 5 is located.

As shown in FIG. 5, the undercover 4 is a thin plate made of resin and has a through hole 3 for screwing the upper part of the undercover 4 to the lower part of the glove box 3.
0,30, a flange 7 for fixing a lower portion of the under cover 4 with a resin clip to a dash panel 8 disposed in the lower part of the glove box 3 shown in FIG. 6, and the under cover for the backbone 5, which is a stationary portion. And a flange 6 for fixing a resin clip to the four side portions.
The flanges 6 and 7 are provided at the ends of the under cover 4 and project downward at a substantially right angle to the under cover 4, and through holes 6a and 7a are formed at substantially the centers thereof. .

Here, reference numeral 9 in FIG. 6 indicates a wheel house, and 10
Shows a trim and 11 shows a front fender panel.

When the under cover 4 is fixed to the glove box 3, the dash panel 8 and the backbone 5, all the through holes 30, 30, 6a, 7a should be aligned with the mounting parts (holes) of the mating parts. Since the fastening work must be performed while supporting the under cover 4, workability is extremely poor. Therefore, in order to improve the workability, the above-mentioned resin clip serving as the locking portion is sub-assembled, that is, temporarily attached to the flanges 6 and 7.

This resin clip is shown in detail in FIGS. 7 to 9.

FIG. 7 shows the mounting holes formed in the backbone 5,
It is a figure showing the state where the resin clip 15 was put together.

The resin casing 15a, which forms the outer shell of the resin clip 15,
It is arranged in the through hole 6a of the flange 6, and is sub-assembled, that is, temporarily attached to the flange 6 with the adhesive 16 or the like in a state where the peripheral portion of the through hole 6a is sandwiched between the left and right ends in the drawing. A through hole 15e is formed substantially in the center of the resin casing 15a, and the through hole 15e is composed of a cylindrical hollow portion 15c and a conical hollow portion 15d continuous with the hollow portion 15c. ing. A slidable pin 15b is arranged in the through hole 15e.
The shape inside 15e follows the through hole 15e.

Then, when the portion of the resin casing 15a projecting from the surface 6b of the flange 6 on the backbone 5 side is inserted into the mounting hole formed in the backbone 5, the pin 15b is pushed to the backbone 5 side. Then, since the tip portion of the resin casing 15a rides on the thick portion 15f on the tip side of the pin 15b, the portion of the resin casing 15a protruding inward of the backbone 5 swells and the flange 6, that is, the undercover 4 is attached to the backbone 5 side. Fixed to.

When the under cover 4 is removed from the backbone 5, the pin 15b is further pushed to the backbone 5 side. Then, as shown in FIG. 9, the pin 15b
Since the tip end portion of the resin casing 15a comes to the narrow portion of, the portion of the resin casing 15a protruding inward of the backbone 5 returns to its original state, and the under cover 4 becomes free with respect to the backbone 5 side.

In this way, the resin clip 15 that is attached and detached to and from the backbone 5 with one touch is temporarily attached to the flange 6, so that the fastening operation is extremely easy.

By the way, when attaching and detaching the flange 7 to and from the dash panel 8,
The same is done by the resin clip 15.

(Problems to be Solved by the Invention) By the way, as shown in FIG. 6, the undercover 4 is provided between the undercover 4 and the backbone 5 in order to improve its appearance. The space between the trim and 10 is very narrow. Therefore, in order to attach the undercover 4 to the above-mentioned portion, the undercover 4 is slid between the backbone 5 and the trim 10 so as not to contact the backbone 5 and the trim 10, and the predetermined position, that is, the resin clip 15. The resin clip 15 must be moved to a position facing the hole on the non-moving part side into which the resin clip 15 is inserted. However, as described above, the space between the backbone 5 and the flange 6 is extremely narrowed, and the resin clip 15 is temporarily attached to the flange 6 in advance in order to improve workability. Since it protrudes further outward than the surface 6b, the tip of the resin clip 15 interferes with the side surface of the backbone 5 in some cases, damaging the backbone 5, and there is a fear that the appearance is deteriorated.

An object of the present invention is to attach a resin member to an immovable portion, and at the time of setting the resin member, a locking member protruding from a surface of the flange on the immovable portion side does not interfere with the immovable portion. To provide.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the resin member mounting flange of the present invention is formed integrally with the resin member, and the resin member is provided between the flange and the resin member. Until the locking part reaches the mounting hole formed in the immovable part by laterally moving the locking part so that the locking part does not come into contact with the immovable part, and the locking part is attached to the mounting hole. On the other hand, when it is inserted and fixed, the resin hinge is formed so that the flange can be bent so as to come into contact with the immovable portion.

(Operation) According to the present invention, the flange is formed integrally with the resin member,
The resin hinge formed between the flange and the resin member is
Until the locking portion reaches the mounting hole formed in the non-moving portion by laterally moving the resin member, the locking portion is retracted so as not to contact the non-moving portion, and the locking portion is set in the mounting hole. When it is inserted and fixed with respect to, the flange is bent so as to come into contact with the immovable portion.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an undercover to which a mounting flange according to an embodiment of the present invention is applied. In the drawing, the same functions and functions as those of the above-described conventional art are designated by the same reference numerals, and the description thereof will be repeated. I will omit it because it does.

The first difference between the resin member mounting flange of this embodiment and that of the prior art is that a resin hinge 21 that can bend the flange 20 is provided between the flange 20 and the undercover 4. The resin hinge 21 is provided in parallel with the longitudinal direction of the backbone 5 as a mating member to be fixed (the direction of arrow A in FIG. 1), and the flange 20 swings around the resin hinge 21 as a fulcrum. It is free.

Therefore, until the undercover 4 is moved laterally until the resin clip 15 as the locking portion reaches the mounting hole formed in the backbone 5 as the non-moving portion, as shown in FIG. , So that it does not contact (interfere) with the side surface of the backbone 5 indicated by the dotted line.
20 is swung with the resin hinge 21 as a fulcrum to retract. Then, the contact of the resin clip 15 with the backbone 5 is avoided, so that there is no fear of damaging the backbone 5,
The under cover 4 can be smoothly set in a predetermined position.

Then, when the setting of the under cover 4 to the predetermined position is completed, as shown in FIG. 3, the retracted state is released to a position similar to that of the conventional technique, that is, a position substantially perpendicular to the under cover 4. If the flange 20 is returned, the flange
A portion of the resin casing 15a protruding from the surface 20b on the backbone 5 side of 20 can be inserted into a mounting hole formed in the backbone 5.

As described above, according to this embodiment, when the undercover 4 is attached to the backbone 5, the flange 20 can be swung and retracted with the resin hinge 21 as the fulcrum. It is possible to avoid the interference of the tip of the resin clip 15 protruding from the surface 20b on the backbone 5 side of 20 with the backbone 5.

The under cover 4 and the rung 20 are integrally molded with resin, and at the time of molding, the flange 20 is molded so as to be flush with the flat surface portion of the under cover 4, as shown in FIG. Therefore, it can be manufactured at low cost.

The second difference between the flange 20 of the present embodiment and that of the prior art is that, as shown in FIG. 1, the engagement piece 22 is provided on the side surface of the flange 20 and the engagement piece 22 is provided on the flat surface portion of the under cover 4. The point is that each locking hole 23 for locking 22 is formed.
The locking piece 22 is attachable / detachable to / from the locking hole 23, and is locked when the flange 20 is pivotally retracted with the resin hinge 21 as a fulcrum so that the tip of the resin clip 15 does not contact the backbone 5. It can be locked in the hole 23.

Therefore, until the undercover 4 is moved laterally until the resin clip 15 reaches the attachment hole formed in the backbone 5, as shown in FIG.
If it is locked with respect to, the interference of the tip of the resin clip 15 with the backbone 5 can be avoided.

Then, when the setting of the under cover 4 at the predetermined position is completed, as shown in FIG.
When the locked state is released, the flange 20 is returned to the same position as in the prior art, that is, the position in contact with the under cover 4, and the preparation for mounting the flange 20 is completed.

As described above, according to this embodiment, when the undercover 4 is set to attach the undercover 4 to the backbone 5, the engaging piece 22 is engaged with the engaging hole 23 so that the resin clip Backbone 5 at the tip of 15
Since it is possible to avoid interference with, it is not necessary to continue retracting the flange 20 by hand or the like, and workability is further improved.

The present invention is not limited to the above embodiment,
Various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the resin member is the undercover of the automobile, and the immovable portion is the backbone. However, the invention is not limited to the member. Further, it is not limited to automobile parts.

Further, in the above embodiment, the locking portion is a resin clip, but it is not limited to the resin clip,
In short, any locking part may be used as long as it can be inserted into the mounting hole formed in the immovable part and protrudes from the surface of the flange on the immovable part side.

As described above, according to the resin member mounting flange of the present invention, the flange is integrally formed with the resin member, and the resin member is laterally moved between the flange and the resin member. Until the locking portion reaches the mounting hole formed in the non-moving portion, the locking portion is retracted so as not to contact the non-moving portion, and the locking portion is inserted into the mounting hole. When fixing, since the resin hinge is formed so that the flange can be bent so as to be in contact with the stationary portion, when setting the resin member for mounting the resin member on the stationary portion, from the surface of the flange on the stationary portion side. The protruding locking part does not interfere with the immovable part, which may damage the immovable part,
There is no fear of spoiling the appearance.
