DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view of a bumper guard according to this embodiment, and FIG. 2 is a perspective view showing a bumper guard body without a garnish and a side cover for decoration.
As shown in FIG. 2, the bumper guard body 1 has a horizontally elongated center member 2, a lower member 3 arranged in parallel below the center member 2, and two left and right side members 4 extending in the vertical direction. Is formed in a frame shape.

Each of the members 2, 3 and 4 is made of metal in order to ensure the required rigidity, the center member 2 is formed in a substantially U-shaped cross section, the lower member 3 is made of a circular pipe, and the side member 4 is made of a substantially cross section. It is L-shaped.
Then, the upper ends of the left and right side members 4 are superposed on the front surface and the side end surfaces of the center member 2, and the lower ends are superposed on the front surface of the lower member 3, and are joined by screwing with bolts 5 and nuts 6, respectively. (See the cross-sectional view of FIG. 3).

As shown in FIG. 2, each member 2 to 4 of the bumper guard main body 1 constructed as described above is provided with a mounting hole for mounting an attachment. That is, two circular through holes 7 are formed in parallel on the upper plate of the center member 2, and two mounting holes 8 are formed on the lower plate in correspondence with each of the through holes 7. Further, one mounting hole 9 is formed on each of the front surface and the side surface of the upper portion of the side member 4, and further, mounting holes 10 are formed at the left and right ends of the lower member 3 so as to extend horizontally in the radial direction. In this embodiment, the mounting holes 9 and 10 of the side member 4 and the lower member 3 also serve as through holes for the bolts 5 for joining the members.

On the upper surface of the center member 2 of the bumper guard body 1, a plurality of horizontally elongated flat plate-shaped garnishes 11 for decoration are stacked and elastically engaged with the edge of the upper plate of the center member 2. It can be attached by the claws 12 (see the sectional view of FIG. 4). The left and right side members 4 are covered with a box-shaped side cover 13 having a substantially U-shaped cross section, and a resin clip elastically engaged with a hole provided on the front surface of the side member 4 in a state of being covered from the front. 1
4 can be attached (see the sectional view of FIG. 3).

Therefore, in the bumper guard body 1, the upper surface of the center member 2 and the front and side surfaces of the side members 3 are covered with the garnish 11 and the side cover 13, and the through holes 7 and the mounting holes 9 and 10 are hidden. The garnisher 11 and the side cover 13 are made of resin so that a penetrating portion 15 (shown by a broken line in FIG. 1) necessary for mounting an attachment described below can be easily cut off. As shown in the sectional view of FIG. 5, the bumper guard main body 1 has bolts 26 attached to brackets 29 whose upper ends of the side members 4 extend forward from a vehicle body frame (not shown) through holes in the front bumper 28. And the nut 27.

FIG. 6 exemplifies four types of attachments used by being mounted on the bumper guard body 1.
The attachment shown in (A) is a grille guard 16 made of a circular pipe for protecting the front grille. The left and right ends extend in such a length as to reach the front fender panel and are folded back in a U shape to protect the headlight. 16a
It is a wide type with a mounting bracket 17 welded to each of its folded end portions, and the center 2
A nut 18 is provided at the end of the upright leg portion 16b of the book.

The attachment (B) is a bush bar 19 for protecting the front grill formed by bending a circular pipe into a substantially gate shape, and nuts 20 are provided at both ends thereof. The attachment (C) is a lamp guard 21 for protecting the fog lamp, which is formed by bending a pipe in a U-shape in a horizontal direction, and mounting brackets 22 are welded to both ends thereof. Further, the attachment (D) is a side sill guard 23 formed by bending the pipe into a substantially L-shaped plane so as to wrap around from the left and right front portions of the front bumper to the lower edge of the fender, and a mounting bracket 24 is welded to one end thereof.

As shown in the sectional view of FIG. 7 and the phantom line of FIG. 2, the two upright legs 16b at the center of the grill guard 16 are inserted into the two through holes on the outside of the center member 2. At the same time, the center member 2 is fastened to the center member 2 by a bolt 25 screwed into the nut 18 through the mounting hole 8, and as shown by the cross-sectional view of FIG.
The mounting brackets 17 at the left and right folded end portions are abutted against the front surface and the side surface of the side member 4, and the mounting holes 9 are provided.
It is attached to the bumper guard body 1 by being fastened together with the side member 4 by the above-mentioned member joining bolts 5 and nuts 6 which are passed through. The bush bar 19 is mounted using the two through holes 7 and the mounting holes 8 on the inner side of the center member 2. The mounting mode is the grill guard 16
This is the same as the upright leg 16b.

On the other hand, the lamp guard 21 includes the side member 4
It is mounted by using the mounting hole 9 and the mounting hole 10 of the lower member 3, but the manner of mounting the side member 4 is similar to that of the folded end portion of the grill guard 16. As shown in the cross-sectional view of FIG. 9 and the phantom line of FIG. 2, with respect to the lower member 3, the mounting bracket 22 is inserted into the cylindrical hole of the lower member 3 and the above-described member joining bolt 5 and nut 6 are joined. It is attached by tightening together. Further, the side sill guard 23 is similar to the manner of attaching the lamp guard 21 to the lower member 3. (A) of FIG.
(D) shows a bumper guard equipped with each of the above attachments.

When mounting the attachment to the bumper guard main body 1, the garnish 11 is attached in advance, but it is desirable that the side cover 13 is attached later. In that case, the garnish 11 and the side cover 13 are attached.
The mounting portion 15 shown by the broken line in FIG. 1 is cut off in accordance with the attachment to be mounted.

As described above, the bumper guard of this embodiment can be used by itself, and is based on the frame-shaped bumper guard main body 1, and there are several different designs prepared in advance. By properly installing the attachment, it is possible to diversify the variations of bumper guard design. The appearance of the garnish 11 and the side cover 13 can be improved by covering the attachment portion of the attachment and the unused through holes 7 and the mounting holes 9 and 10 with the garnish 11 and the side cover 13. As a result, the processing can be easily performed.

In this embodiment, the bumper guard body 1
Since the attachment of the attachment can be attached and detached by screwing, the attachment once attached can be replaced with another attachment.
In that case, the garnish 11 or the side cover 13 can be replaced with a new one as needed. Also,
The attachment of the attachment to the side member 4 and the lower member 3 is effective in reducing the number of parts because the bolts 5 and the nuts 6 for joining the members are jointly tightened.

The present invention is not limited to the illustrated embodiment, but can be modified as appropriate without departing from the scope of the invention. For example, the component members of the bumper guard body 1 may be integrally formed as a whole, or may be joined by welding instead of bolts and nuts. Further, when attaching the attachment to the center member 2, the through hole 7 is omitted and the bracket is bolted like the attachment to the side member 4.
You may change to the form fixed by a nut.

[0020]

As described in detail above, according to the present invention,
Since the attachment can be attached to the frame-shaped bumper guard body, it is possible to diversify the design variations based on the bumper guard body, so it is possible to change the design by replacing the entire bumper guard. The bumper guard can be provided at low cost. Further, by providing the garnish or the side cover, it is possible to improve the appearance by hiding the mounting hole and the attachment, which have not been mounted, and hiding the mounting portion.
