Abstract

PURPOSE:To limit the corrugated deformation of a bumper guard and as well to eliminate a gap between the guard and a bumper front wall, by resiliently contacting and locking the end of a bumper guard upper wall to a flange. CONSTITUTION:Since the end of a bumper guard upper wall 2b which is received in a groove 4 in a bumper front wall 1a, is resiliently contacted with and locked to a flange part 5, the upper wall 2b is precisely aligned with the front wall 2b with no parting gap between the end of the upper wall 2b and the flange 5, thereby the appearance of the bumper guard is made satisfactory. Further, the end of the upper wall 2b tends to be chronogically corrugated, but is limited to deform by the frange 5 on the upper side surface of the groove 4 and the lower side surface of the groove 4. Accordingly, the end of the bumper guard upper wall 2b is prevented from being corrugated, greatly.

Description

[Detailed description of the invention] The present invention relates to a bumper guard mounting structure.

Even on the back of an automobile bumper, a bumper guard is installed on the front wall of the bumper in order to avoid permanent deformation of the bumper and damage to its appearance in the event of a minor collision with a metal bumper. There are n.

Figure 1 shows the usage state of a bumper equipped with such a bumper guard 7. Two bumper guards made of elastic material such as rubber or resin are installed on the front wall /a of the metal bumper. . As shown in FIG. 2, this bumper guard 2 is formed into a substantially U-shaped section, and has a lip 2a protruding from the center of the rear surface of the entire bumper front wall. fi
Bolts in several places. Tighten nuts 3 and remove the terminals of the upper wall λb and lower wall 2C of the bread and burger joints? It is brought into contact with the front wall of the bumper.

By arranging two bumper guards in front of the bumper in this way, the bumper guard cushions the bumper guard with its own elasticity in the event of a minor car collision, and prevents elastic deformation from repeating later and completely damaging the exterior. This can be avoided and is also very advantageous in terms of pedestrian safety measures.

However, in such a conventional configuration, since the bumper guard 2 is made of an elastic material such as rubber or resin as described above, it expands and contracts due to changes in outside temperature. The i direction increases in the horizontal direction [4ru. For this reason, the upper and lower walls 2b of the bumper guard λ
, 2Q are wavy and deformed over time as shown in FIG. 3, and the upper and lower walls -2b.

The end of 2C is hanging down 9, it is floating and a gap is created between the bumper front wall / &, especially the bumper guard earthen wall 2
Part b was easily noticeable, and this gap was large and conspicuous, deteriorating the overall appearance and lowering the overall sense of quality.

In view of such conventional problems, the present invention can completely prevent the waving deformation of the end of the upper wall of the bumper guard, which is most visible from the outside, and also prevent the undulating deformation of the end of the upper wall of the bumper guard and the front wall of the bumper. Is there a bumper guard mounting structure that eliminates gaps? The entire purpose is to provide
6 Therefore, in the uninvention, a jaw is entirely formed in a portion of the front wall of the bumper that corresponds to at least the end of the upper wall of the bumper guard, and the end of the upper wall of the bumper guard is elastically abutted and locked to this jaw. We are trying to regulate the saka-uchi deformation.

Hereinafter, embodiments of the present invention will be described with reference to the drawings and the same parts as the conventional structure. I will attach and explain it.

That is, as shown in FIG. 4, the non-invention b is a bumper guard having a U-shaped cross section made of an elastic material such as rubber or resin on the outer surface of the front wall/a of the bumper. There are bolts that protrude on the part or fall in multiple places on the boo 2a part. It has a structure in which it is installed by tightening nuts 3, and there is a part of the bumper front wall/a corresponding to the end of the bumper guard upper wall 2b that has a slightly wider thickness and width at the end of the bumper guard upper wall 2b. Set up 4t and hit the jaw! Sound is formed, and the end of the bumper guard upper wall-2bcD is accommodated in the bay≠, and the end of the earthen wall is placed in the jaw S! It is in ballistic contact and is locked.

If the structure of the above embodiment is used, the bumper guard upper wall-2b
The end of the bumper guard is accommodated in the groove of the front wall of the bumper, and since the end of the bumper guard upper wall 2b is resiliently engaged with the jaw j, the end of the bumper guard upper wall 2b is There is no parting gap between the bumper guard top wall 2b and the bumper front wall 2b, and the bumper front wall 2b and the bumper front wall 2 are tightly aligned, resulting in a good-looking appearance.

In addition, the end of the bumper guard upper wall 2b tends to become wavy and deformed over time, but a part of this upper wall end has a groove ≠ the jaw on the upper side! The deformation is regulated by the lodging side and n1,
There is no possibility that the end portion of the bumper guard upper wall 2b will be greatly wavy and deformed, thereby deteriorating its appearance.

The embodiment shown in FIG. 5 uses reinforcement 6t bolts on the pan/<-gil wall/a. The nut 7 is fixed, and the snap part 2d protruding from the rear side of the bumper guard λ is fully inserted into the mounting hole 6b provided on the front wall 6a of this reinforcement 6, and the snap part 2d is fully inserted and engaged to attach it to the upper wall of the bumper guard. 2bf is supported by the soil wall 6C of the reinforcement B on the lower side, and the end of the bumper guard upper wall 2b? The jaw formed on the front bumper wall/a! It comes into contact with and is locked.

Therefore, even in the case of this embodiment, the upward movement of the end of the bumper guard upper wall 2b is 0, and the downward slope is 0. Moreover, the reinforcement upper wall 6C can suppress the waving deformation of the end of the bumper guard upper wall 2b over time. This can be controlled by the upper reinforcement wall 6C.

In some cases, the end of the bumper guard lower wall 2C may also be attached to the lower side of the bumper front fi/a. It is also possible to form a jaw part to restrict hanging deformation or undulating deformation.

As described above, according to the invention, the end of the upper wall of the bumper guard, which is most visible from the outside, extends below the jaw of the front wall of the bumper and comes into elastic contact with the jaw.

There is a molding error in the bumper guard because it is locked.

Even if shrinkage occurs, it is possible to avoid a parting gap between the end of the upper wall of the bumper guard and the front wall of the bumper, and the wavy diamond shape of the end of the upper wall of the bumper guard can be controlled by this jaw. Since it can be made into a tray, it does not make the appearance unpleasant, and it has a great practical effect of improving the quality of the tray.
