[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a license plate mounting base on which a license plate of an automobile can be mounted at a desired inclination angle.
[0002]
[Prior art]
Conventionally, the number plate mounting structure for automobiles is a structure in which the number plate is applied to the center surface of the front bumper or rear bumper and fixed directly with bolts and nuts, or L-shaped on the front bumper or rear bumper. Widely adopted is a structure in which a plurality of short stays that are refracted into a shape are projected, and the four corners of the back of the number plate are applied to the tip surfaces of these stays and fixed with bolts and nuts. Yes.
[0003]
[Problems to be solved by the invention]
However, according to the license plate mounting structure as described above, the former has a mounting structure in which the four-side periphery of the license plate protrudes from the front bumper and the rear bumper, and the latter has a mounting structure protruding from the stay. As a result, the corners of the license plate are easily bent due to collisions with other objects, and the appearance of the license plate is notably damaged, and the number displayed on the license plate is difficult to recognize due to the bending. Will occur.
[0004]
Furthermore, the front bumper and rear bumper are curved in a convex arc shape in the length and width directions from the viewpoint of automobile design. For this reason, a flat recess is formed in the lower central part of the bumper in the longitudinal direction, and a license plate is installed in the recess. In this structure, the license plate is immersed in the recess. It becomes difficult to confirm the number of the license plate from the oblique side.
[0005]
In addition, when the surface on which the license plate is mounted is curved in a gentle convex arc shape as described above, or when the vertical width of the flat recess on which the license plate is mounted is narrower than the vertical width of the license plate Since the number plate is fixed with bolts and nuts only on both sides at the top end of the license plate, the license plate is suspended downward from the fixed part. In the same way as above, there are problems such as the appearance being damaged.
[0006]
Furthermore, the license plate is mounted at a low height, such as a bumper of an automobile, and when checking the license plate, the license plate is always in an attitude of overlooking the license plate. However, since the license plate is mounted vertically, the license plate number display direction and the direction of viewing the license plate do not face each other, and it may be difficult to confirm the number at a glance.
[0007]
The present invention has been made in view of the above-described problems. The object of the present invention is to allow the license plate to be firmly attached in a stable state without being broken or recessed, and the bumper. The plate mounting surface can be easily and accurately mounted even if the plate mounting surface is curved in a convex arc shape, and the license plate is tilted upward and obliquely at a desired angle. It is in providing a mounting plate for a license plate that can be used.
[0008]
[Means for Solving the Problems]
To achieve the above object, the license plate mounting base of the present invention, as described in claim 1, is a horizontally-long rectangular license plate mounting plate that is inclined forward from the upper end toward the lower end. It consists of a peripheral frame that protrudes rearward from the four-side periphery of this license plate mounting plate, and an upper frame portion that protrudes rearward from the upper end of the license plate mounting plate in this peripheral frame is formed in a narrow frame portion The lower edge frame portion protruding rearward from the lower end is formed into a wide frame portion, and the both side frame portions connected between both ends of the upper and lower frame portions are gradually moved from the upper end toward the lower end. It is formed in a vertically elongated trapezoidal shape, and the rear end surface of the peripheral frame is mounted on a mounting surface formed by the central portion of the bumper, and is fixed by a bolt .
[0009]
In the pedestal for mounting the license plate, the invention according to claim 2 is such that the size (area) of the inclined mounting surface of the license plate mounting plate is greater than the size of the license plate, and the upper and lower portions are A pair of bolt insertion holes is provided, and the invention according to claim 3 is characterized in that the license plate mounting plate and the peripheral frame are integrally formed of a hard synthetic resin. The invention according to claim 4 is characterized in that a string-like packing is detachably attached to the protruding end of the peripheral frame over the entire periphery.
[0010]
[Action]
The rear end surface of the peripheral frame that protrudes rearward from the four-side periphery of the license plate mounting plate is applied to the front face of the center of the front bumper, rear bumper, etc. (hereinafter referred to as the mounting surface), and the bolts provided on the mounting plate are inserted The bolt is inserted through the hole and fixed by being inserted into a mounting hole or a screw hole provided at the center of a front bumper, a rear bumper or the like. In this mounting state, the license plate mounting plate is inclined obliquely upward toward the front. Therefore, when the license plate is mounted on the front surface of the mounting plate, the license plate faces the person who confirms the number. The number on the license plate can be recognized at a glance. The number plate may be attached to the front surface of the attachment plate on the pedestal at the same time as the pedestal is attached to the mounting surface.
[0011]
In addition, it can also be attached to the mounting surface in a state where the pedestal is turned upside down and the license plate mounting plate is inclined obliquely downward. In any case, by attaching the string-like packing to the rear end of the peripheral frame of the pedestal over the entire circumference, the rear end of the peripheral frame can be accurately attached to the mounting surface via the string-like packing. In addition to being able to be fixed, it is possible to prevent the pedestal mounting surface of the front bumper and the rear bumper from being scratched by the rear end surface of the peripheral frame of the pedestal by this string packing.
