Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bumper structure, and particularly to masking countermeasures during painting.

[0002]

[Prior art]

 Generally, when forming an unpainted part on the bumper or painting two or more colors, the painted surface is masked before painting. For example, a bumper structure in which a masking jig is mounted and coating is performed by bending the masking jig as disclosed in Japanese Utility Model Laid-Open No. 64-39870, so that a vertical bar (vertical rib) is formed. The parts that do not require painting are covered and spray-painted.

[0003]

[Problems to be solved by the device]

 However, in the above bumper structure, there is no structure to share a masking jig, so it is necessary to create a masking jig for each unneeded portion with a different length, and it is necessary to create many types of masking jigs. There was a problem.

Further, as shown in FIG. 5 of the above publication, the masking jig having the vertical ribs has a structure in which the upper and lower ends of the masking jig come into contact with the bumper edges and the horizontal rails (horizontal ribs) in the air passage. Therefore, when removing the masking jig after painting, there is a problem that the upper and lower ends of the masking jig are likely to damage the edges of the air passages and the painted surface of the lateral ribs.

The present invention has been made in view of the above points, and makes it possible to use a common masking jig even when masking vertical ribs having different heights, and at the time of removing the masking jig. The purpose is to make it difficult to damage the painted surface of the bumper.

[0006]

Means for Solving the Problems In order to achieve the above-mentioned object, a solution means devised by the present invention is that a plurality of vertical ribs extending in the vertical direction are installed in an opening, and the vertical ribs are coated with a masking jig during coating. Targeting a bumper structure where the masking is mounted, the plurality of vertical ribs are formed so that the masking target is mounted on the lower part and the masking tool is mounted, and the masking target has a substantially constant length. A bulging step portion, which is provided above the masked portion and bulges outward from the masked portion, is provided.

[0007]

[Action]

 With the above configuration, in the present invention, the plurality of vertical ribs are provided on the masked portion so that the masked portion having a substantially constant length is formed, and the vertical ribs are positioned outward of the masked portion. Since each bulging step has a bulging step, the bulging step serves as a dimension adjustment part that allows masking jigs with the same vertical length to be mounted on vertical ribs with different heights, so that the heights differ. It is possible to attach masking jigs with the same vertical length to the vertical ribs.

Further, since the bulging step portion is formed on the vertical rib, a dimensional margin can be provided for removing the masking jig by the amount of the bulging step portion. The painted surface near the upper and lower ends is less likely to be damaged.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a front portion of a vehicle to which a bumper mounting structure according to an embodiment of the present invention is applied. In the present embodiment, the case where the bumper is attached to the front portion of the vehicle body will be described, but the present invention is also applicable to the case where the bumper is attached to the rear portion of the vehicle body.

In the figure, an opening 3 is formed in the center of the bumper 1, and one horizontal rib 5 and a plurality of vertical ribs 7, 7 are laid in a grid pattern in the opening 3. .

As shown in FIG. 2, the horizontal ribs 5 are arranged downward from the center of the opening 3 in the vertical direction, whereby the vertical ribs 7 are located above the horizontal ribs 5 and are slightly longer than the upper vertical ribs 7A. And the lower vertical ribs 7B which are slightly shorter than the horizontal ribs 5, and the upper vertical ribs 7A and the lower vertical ribs 7B having different heights are both unpainted parts, and the masking jig 9 is used for painting. Is installed.

As shown in FIG. 3, as a feature of the present invention, a plurality of upper vertical ribs 7A and lower vertical ribs 7B include a masked portion 11 to which the masking jig 9 below is mounted and a masked portion 11 to be masked. Each of the masking portions 11 and the bulging step portion 13 is provided. The bulging step portion 13 is provided so that the masked portion 11 having a substantially constant length is formed, and the bulging step portion 13 is different between the upper vertical rib 7A and the lower vertical rib 7B having different heights. Are set to have different heights. Further, the bulging step portion 13 bulges outward from the masked portion 11 so that the surface thereof is flush with the surface of the masking jig 9 when the masking jig 9 is mounted on the masked portion 11. It is formed out.

On the other hand, as shown in FIG. 2, the masking jig 9 is formed in a U-shape in plan view so as to cover the masked portions 11 of the upper vertical ribs 7A and the lower vertical ribs 7B. Locking claws 15 projecting toward the inner surface are formed at the left and right edge portions.

In each masking jig 9, the locking claws 15 are locked to the end portions 7a of the upper vertical ribs 7A and the end portions 7a of the lower vertical ribs 7B, respectively, so that the upper vertical ribs 7A are covered. The masking portion 11 and the masked portion 11 of the lower vertical rib 7B are mounted.

Next, the coating procedure of the bumper 1 will be described. As shown in FIG. 4, the masking jig having the same vertical length is used for the upper vertical rib 7A and the lower vertical rib 7B having different heights. The tool 9 is attached. Then, as shown on the upper vertical rib 7A side in the figure, the bumper 1 is coated by spray coating with the coating gun 17.

Since the bulging step portions 13 are formed on the upper vertical ribs 7A and the lower vertical ribs 7B, the masking jig 9 can be removed by a dimensional margin corresponding to the bulging step portions 13. As shown on the side of the middle and lower vertical ribs 7B, after the coating is finished, the masking jig 9a can be removed by inclining it obliquely upward, and the openings near the upper and lower ends of the upper vertical rib 7A and the lower vertical rib 7B can be opened. The masking jig 9 is removed without damaging the edge of the portion 3 or the coated surface of the lateral rib 5.

As described above, according to the present invention, the plurality of vertical ribs 7 are provided on the masked portion 11 so that the masked portion 11 having a substantially constant length is formed. Since the bulging step portion 13 that bulges outward from the masked portion 11 is provided, the bulging step portion 13 has upper and lower vertical ribs 7A and lower vertical ribs 7B having different vertical lengths. The masking jig 9 serves as a dimension adjusting portion for mounting the same masking jig 9, and the upper and lower vertical ribs 7A and 7B having different heights can use the masking jig 9 having the same vertical length. The masking jig 9 can be shared.

Further, due to the bulged step portion 13, there is a dimensional allowance in removing the masking jig 9, and it is possible to prevent the painted surface of the bumper 1 from being damaged when the masking jig 9 is removed.

Since the bulging step portion 13 is located in the depth direction of the opening 3 of the bumper 1 and the bumper 1 is considerably lower than the eye position of the person, it is difficult for the person to enter the eye. The bulging step portion 13 does not adversely affect the appearance.
