Description

[Detailed Description of the Invention] This invention relates to an improvement of an automobile bumper attachment device.

A bumper is attached laterally to the front or rear of an automobile to protect the body in the event of a collision. If the bumper is installed out of position with respect to the body, it will look bad. Particularly in automobiles that use a chassis frame, the body is attached to the chassis, and
Attach the bumper to the chassis. Therefore, misalignment between the body and the bumper is likely to occur. It is necessary to tighten the bumper while checking the front and rear, left and right, and top and bottom positions between the bumper and the body. The bumper is fastened to the chassis frame via a retaining piece, but
Since the holding piece is fastened to the back of the bumper, it is difficult to insert a spanner into it after it is attached to the chassis frame.
Therefore, especially if there is a left-right misalignment between the holding piece and the body, the holding piece must be removed from the chassis frame and adjusted again, making the assembly work troublesome.

In view of the above, the present invention has been made to improve the bumper mounting and position adjustment so that the embodiment of the present invention will be described below with reference to the drawings.

A holding piece 2 is provided which has a substantially T-shaped bent piece 1 with the upper and lower front ends thereof bent in opposite directions to the left and right. A long hole 3 whose major diameter coincides with the longitudinal direction of the vehicle body is provided at the rear of the holding piece 2, and a bolt 4 is passed through the long hole 3 and fastened to the left and right chassis frames 5 or the body 6.
Then, the upper and lower surfaces of the bumper 7 are aligned with both bent pieces 1 of the holding piece 2, and the bumper 7 is fastened with bolts 9 into long holes 8 provided in the bent pieces 1 whose major diameters coincide with the left-right direction of the vehicle body. A notch hole 10 is provided in the lower surface of the bumper 7 on the same central axis as the upper bolt 9 mounting hole.

The effect will be explained.

The bumper 7 is attached to the chassis frame 5 or the body 6 via the holding piece 2 with the bolts 4 and 9.
After temporarily assembling the body 6, adjust the position to make sure it is not misaligned with the body 6. In that case, if the bumper 7 is misaligned in its front and rear and up and down positions, it can be adjusted by loosening the bolts 4 and moving the holding pieces 2.
Also, if the bumper 7 is misaligned from side to side, loosen the bolts 9 to adjust it. The bolts 4 can be worked on by inserting a wrench from below even after the bumper 7 is temporarily assembled. Also, a wrench is inserted into the bolt 9 from the inside, and a notch hole 10 in the bumper 7 is inserted into the bolt 9.
You can insert a box spanner and tighten it. In this way, the assembly and position adjustment of the bumper 7 can be easily performed.

As explained above, this invention provides a holding piece that is approximately T-shaped and has its front end top and bottom bent in opposite directions left and right to form a bent piece. Tighten the bolts inserted through the matching long holes to the chassis frame or body, and at the same time, drill long holes whose long diameters match the left and right direction of the vehicle body in the upper and lower bent pieces of the front part of the above-mentioned holding piece. The top and bottom of the bumper, which has notched holes on the same central axis as the upper bolt mounting holes, are fastened with bolts inserted through the long holes, so the position can be adjusted even after the bumper has been temporarily assembled. . In particular, the bumper and the holding piece are easy to adjust because a spanner can be inserted into the lower side from the inside, and a box spanner can be inserted into the upper side through the cutout hole. In this way, it is possible to tighten while looking at the position relative to the body, up and down, left and right, and front and rear, which simplifies assembly adjustment and improves work efficiency. Further, the holding piece can be made inexpensive by press-forming a steel plate.
