Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an improvement in a food garnish structure.

[0002]

2. Description of the Related Art For example, FIG. 1 of Japanese Unexamined Utility Model Publication No. Sho 63-57179 entitled "Drainage structure of a lid garnish for an automobile" shows a lid garnish 3 (symbols are those described in the gazette. The same applies hereinafter). The lid garnish 3 is attached to the rear edge of the hood (lid) 1. That is, since it is difficult to obtain continuity to the windshield 2 from a bonnet (lid) 1 formed by pressing a metal plate, the lid garnish 3 whose shape is freely determined by resin molding is attached to the bonnet (lid). 1) A structure that is retrofitted to the trailing edge is widely used.

[0003] Incidentally, the lid garnish 3 undergoes a large thermal expansion under the scorching sun, and may come into contact with the fender garnish 4, 4 or the like. In order to avoid this, if a large allowance for expansion is expected, a large gap is generated between the fender garnishes 4 and 4 in cold weather, which is not preferable.

FIG. 1 of Japanese Patent Application Laid-Open No. 5-96935, entitled "Cowl Looper Structure", shows a cowl looper 12 divided into left and right sides. However, by inserting the pin 36 into the through hole 24 (see paragraph 4 of the publication, paragraph number [0017]) formed in the middle part in the vehicle width direction, the cowl louver light 14 is expanded and contracted along the long hole 26, By inserting a pin 48 into a long hole 46 provided in the cowl louver right 14, the cowl louver left 16 is expanded and contracted along the long hole 28, thereby adopting a structure. Since the long hole 46 extends in the front-rear direction of the vehicle body, it acts as a simple round hole in the vehicle width direction.

[0005]

The problem to be solved by the present invention is as follows.
In the cowl louver structure disclosed in Japanese Patent No. 96935, a structure divided into two parts is used for convenience. However, thermal expansion and contraction is the same as sliding right and left starting from the center in the vehicle width direction. Therefore, the same problem as in Japanese Utility Model Laid-Open No. 63-57179 occurs.

Accordingly, an object of the present invention is to provide a hood garnish structure capable of absorbing thermal expansion and contraction so as not to interfere with accessories such as fender garnish.

[0007]

According to a first aspect of the present invention, there is provided a hood garnish to be retrofitted to a trailing edge of a hood, wherein the hood garnish is detachably fixed to the hood by a plurality of attachment mechanisms. The left and right ends are fixed to the hood and divided at the center of the vehicle width.
The garnish is composed of a right garnish body, and these left and right garnish bodies are thermally expanded and contracted to the center of the vehicle width.

Since the hood garnish is fixed at both ends and divided at the center, there is no possibility that the hood garnish protrudes from the left and right ends of the hood, and the inconvenience that the hood cannot be opened can be solved.

According to a second aspect of the present invention, the mounting mechanism includes an elongated slot hole extending in the direction of thermal expansion and contraction, and a flange portion bulging out from the lower surfaces of the left and right garnish bodies so as to be substantially parallel to the hood. A hairpin hole formed in the flange,
A locking member inserted from the opening of the hairpin hole and the tip of which engages with the slot hole, and wherein the flange portion has a front opening flange portion facing the front of the vehicle and an opening facing the rear of the vehicle. And a rear opening flange portion.

When a wax or a rag is applied, a force in the front-rear direction of the vehicle body is applied to the hood garnish. In the present invention, the locking member is provided with the one in the rear direction of the vehicle and the one in the front of the vehicle, so that the hood garnish does not come off by applying wax or a rag, and the hood garnish does not come off during traveling. It is also possible to avoid occurrence of inconvenience such as deviation.

[0011] Claim 3 is that the left and right garnish main bodies are
A large number of dimples are integrally formed at the time of molding so that the cross section has a substantially wavy shape.

The bending rigidity of a corrugated sheet is much higher than that of a flat sheet. By forming a large number of dimples integrally on the left and right garnish main body and making the cross section almost wavy,
Increase bending rigidity and bending rigidity. If the rigidity of the left and right garnish bodies is low, they will bend during assembly and the assembling work will be troublesome, but according to the present invention, the rigidity is high so that the left and right garnish bodies can be easily assembled. Can,
The assembly workability is improved.
