Description

[Detailed description of the invention] This invention attaches the upper garnish to a part of the instrument panel with screws, and also connects the screw insertion opening provided in the upper garnish to a blind cover. This relates to a garnish mounting structure closed with a garnish.

As shown in Figure 8, there is an instrument 1-
There is one in which the second part of the panel 1 is covered with an upper garnish 2 formed separately. This upper garnish 2 is provided with a mounting protrusion 2a that protrudes downward as shown in FIG.
Four parts 2b for installing screws are formed on the second part. Moreover,
A bracket 3 is fixed to a part of the instrument panel 1, and a mounting protrusion 2a is attached to the bracket 3 with screws 4.
is fixed. The head 4a of this screw 4 is disposed within the screw disposing recess 2b, so that the appearance of the screw 4 may be spoiled. A structure similar to this type of mounting structure is disclosed in Japanese Patent Application Laid-open No. 1851-126 (1983).

Also, the above-mentioned screw placement recess 2b is made shallower.

When tightening workability of screw 4 is improved, head 4a of screw 4
may protrude from the soil surface of Upper Carnish 2. In this case, the appearance of the installation will be poor, so
As shown in Figure 0, the bottom surface 2C side of the screw installation recess 2b.
There is one in which a protrusion 2d forming a part of the part is embossed near the part so as not to spoil the appearance.

However, in the above-mentioned mounting structure, the screw mounting recess 2b
-1 is open on one side, so this screw installation recess 2
It was easy for fine dust to accumulate on b, which was not very desirable.

In view of this, conventionally, as shown in FIG. 11, a plate-shaped mounting bracket 5 is disposed below the upper garnish 2, and both ends of this mounting bracket 50 are fixed to the lower surface of the upper garnish 2. A bent protrusion 5a projecting downward is provided at the middle part of the bracket 5, and this bent protrusion 5a is fixed to the bracket 3 with screws 4, and at the same time, the upper garnish 2 is provided opposite to the bent protrusion 5a. A carnish mounting structure has been considered in which a screw insertion opening 6 is provided and the screw insertion opening 6 is closed with a blind cover 7 made of synthetic resin.

In this configuration, since the screw insertion opening 6 is opened by the blind cover 7, even if dust or the like accumulates on the bent protrusion 5a, this part will not be visible and the appearance will not deteriorate.

Moon - Mingfu - Everyone trying to leave - Saleson, however,
The work of screwing the bent protrusion 5a to the bracket 3 is done downward through the small screw insertion opening 6, so it is very difficult to align the screw 4 with the small screw hole 3a in a predetermined direction. Since the sides of the bent protrusion 5a are open, there is a risk that the screw 4 may come off the tightening tool (not shown) and fall from the side of the bent protrusion 5a during screw fastening work. In order to prevent this screw 4 from falling, the conventional method of tightening was to magnetize the tip of the tool and attach the screw to this tip, thereby preventing the screw from falling. Even if such a tool is used, the screw 4 may come into contact with the screw insertion opening 6 of the bubble sealing bracket 1-5 or the blind lid 7.

There was a risk that the product would fall from the side of the bent protrusion 5a.

Further, the blind M7 is fitted and fixed in the screw insertion opening 6 by locking the integral locking claws 7a, 71) on the edges of the screw insertion opening 6, but the locking claw 7a.

Since the length of 7b cannot be made long enough, the claws 7a and 7 are attached to the retainer 1.
It was not possible to provide a large amount of engagement with the edge of the screw insertion opening 6, and the locking claws 7a, 7b were loosely engaged with the edge of the screw insertion opening 6, making them easy to come off. Moreover, since the locking claws 7a, 7b are short, the locking claws 7a, 7b may be bent by a force of -1 or more than the allowable stress during the installation work of the blind cover 7, and may be permanently deformed. In this case, the locking claw 7a,
7b hardly bites into the edge of the screw insertion opening 6, so the blind cover 7 easily comes off. Furthermore, when the blind lid 7 is heated to a high temperature by direct sunlight, the synthetic resin blind lid 7 softens, so that the locking claws 7a and 7b are prevented from biting into the edge of the screw insertion opening 6. There was a problem that the screws became loose and easily came off.So, this invention has been developed to prevent screws from coming off the tool and falling into the screw insertion recess during screw tightening work. , the screws do not fall from the sides of the mounting bracket, their positions do not shift much, and the screws can be immediately re-aligned to the specified positions, and the strength and rigidity of the bubble sealing bracket 1- can be increased. The locking claws of the blind cover, that is, the claws for snap fins 1 to 1, can be made sufficiently long to prevent permanent deformation of the snap fit claws when the blind cover is fitted into the screw insertion opening, and the snap fit claws can be made sufficiently long. The object of the present invention is to provide a garnish mounting structure that can be pushed in the biting direction against a locking piece on the edge of an opening for screw insertion.

Recess To achieve this purpose, the present invention provides an upper garnish provided at the upper part of the instrument panel, and a plate-shaped recess provided on the lower surface of the upper garnish.
The bracket is fixed, and a bent protrusion that protrudes downward is provided at the middle part of the bracket 1-, and a screw is inserted into the bent protrusion-1 of the upper garnish. An opening 1) is provided for the mounting bracket 1.
- is fixed to the instrument panel with a screw provided in a screw installation recess on the bending protrusion, and the screw insertion opening is closed with a blind lid; A side wall facing one side is provided on the side of the protrusion, a locking piece is provided on the upper garnish that protrudes toward the outside of the side wall, and snap fins 1 to 1 provided on the blind lid are provided with a locking piece protruding toward the outside of the side wall. The garnish mounting structure is characterized in that the garnish is engaged with the locking piece and is brought into contact with the side wall so as not to be bent in a direction away from the locking piece.
