Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating the principle of the present invention.

Left and right headlight lenses 2 of an automobile 1
The suction discs 3 are respectively sucked to the centers of the headlights (hereinafter referred to as headlights), and then the cords 4 of the same length are extended toward the shaft 6 of the front stand 5 (see FIG. 2). On the other hand, a screen 7 is installed on the shaft 6 so as to be rotatable and fixable via a boss 8 (see FIG. 3) symmetrically with respect to both wings.
A hook 9 is attached to the boss 8 at the center of the boss 8, and an extended end 4 e of the cord 4 is connected to the hook 9. Here, the extended end 4e of the string body 4 may be connected to the left-right symmetric position of the screen 7 without intersecting in the middle as shown by a two-dot chain line (in the drawing, the position is symmetric from the center. It may be open).

After the setting, the stand 5 is set back so that the tension of the right and left cords 4 is balanced, and the line connecting the front of the headlight 2 and the screen 7 are set.
A line 11 extending parallel to the irradiation surface 10 from the midpoint of the screen 7 and the midpoint 12 of the headlight 2 coincides with each other. In this state, the relationship between the screen 7 and the shaft 6 of the stand 5 is fixed (the boss 8 is fixed to the shaft 6 by turning the clamp handle 13 (see FIG. 3) of the boss 8), and the preparation for the illumination position inspection is completed. . Here, a ball bearing or a roller bearing may be interposed in order to further ensure the rotational relationship between the shaft 6 of the stand 5 and the screen 7.

Next, this embodiment will be described in detail with reference to FIG. The extension end 4e of the cord body 4 extending from the suction disk 3 (see FIG. 1) sucked to the headlight 2 is connected to a locking piece 14 fitted to the shaft 6 of the stand 5. The positional relationship between the locking pieces 14 and the irradiation surface 10 of the screen 7 is such that the bisector 11 of the angle θ formed by both the locking pieces 14 (see FIG. 1) is perpendicular to the irradiation surface 10 of the screen 7. I am trying to be.

On the other hand, the shaft 6 of the stand 5 has a screen 7 with scales 15 and pointers 32 symmetrically on both sides thereof.
The bracket 16 is attached by a bracket 16 via a support rod 32. The bracket 16 forms a split clamp 17 and can be tightened and loosened by turning a clamp handle 13. Therefore, with the clamp handle 13 of the bracket 16 loosened (the screen 7 becomes rotatable about the shaft 6), the stand 5 is retracted, and the tension of the cord 4 extending from the headlight 2 is balanced. When the front surface line of the headlight 2 is set in parallel with the irradiation surface 10 of the screen 7, and a line extending in a direction perpendicular to the irradiation surface 10 from the midpoint of the screen 7 (the axis of the shaft), Then, the intermediate point 12 of the headlight 2 coincides, and the preparation of the inspection certificate for the illumination position is completed. The curved mirror 18 attached to the top of the shaft 6 of the stand 5
Is for roughly grasping the setting situation of the automobile 1 to be inspected.

A more specific example will be described with reference to FIGS. Adsorbing the suction disc 3 to the headlight 2 of the vehicle and extending the cord 4 of the same length from it is the same as in the above-described example.

A locking piece 14 for connecting the extended end 4e of the cord 4
The lower part is integrated with the lower boss 8 ′, the boss 8 ′ is fixed to the shaft 6 by a set bolt (not shown), and the bracket 16 is loosened by the clamp handle 13. It is loosely fitted to the shaft 6.

The string 4 extending from the suction disk 3 adsorbed to the headlight 2 is connected to the two locking pieces 14, and the stand 5 is retracted so that its tension is balanced.
Only 4 'rotates around the shaft 6. Therefore, in this example, since the front line of the headlight 2 and the irradiation surface 10 (see FIG. 1) of the screen 7 are not parallel at this stage, the following operation is performed.

That is, the indicator 19 is directed from the rear surface of the upper bracket 16 supporting the screen 7 toward the locking piece 14.
And a position adjusting rod 21 extends downward from the front surface via the block 20.
Passes through a screw box 22 for adjusting the screen position provided on the lower boss 8 ′ in the middle thereof, and a support tube 23 of the screen 7 is integrally provided at the end.

As shown in FIG. 4, the screw box 22 for adjusting the screen position is connected to the male screw 24 from the lower boss 8 '.
A male screw 24 is rotatably fitted to the arm 25 and screwed into a female screw 26 of the position adjusting rod 21. A knob 27 is fixed to one end of the male screw 24. The rotation of the position adjusting rod 21 is caused by the forward and reverse rotation of the screen 27, and as a result, the screen 7 is rotated.
Position can be adjusted.

As shown in FIG. 5, the locking piece 14 is provided with a hole 28 fitted into the shaft 6 and a small hole 29 connecting the cord 4 on a line passing through the center thereof.
The inclined side 30 is formed at a position beyond the center of the line. The two locking pieces 14 thus formed are vertically symmetrical (one is turned upside down), fitted to the shaft, and the small hole 29 is connected to the extension end 4e of the cord 4 extending from the left and right headlights 2. When the tension is balanced, the corner 31 sandwiching the inclined side 30 coincides with a line extending at a right angle from the midpoint between the headlights 2.

Accordingly, by rotating the screen position adjusting knob 27 so that the corner portion 31 sandwiching the inclined side 30 and the index 19 vertically provided from the upper bracket 16 coincide with each other, the front line of the headlight 2 is aligned with the front line. Screen 7
The center of the shaft 6 coincides with a line extending parallel to the irradiation surface 10 and extending perpendicularly from an intermediate point between the headlights 2.

When setting the inspection tool, the height of the headlights 2 of the automobile 1 and the height of the screen 7 of the tool must be matched. This height adjustment is performed by loosening the clamp handle 13 of the bracket 16. After the adjustment, the collar of the shaft 6 (not shown)
Abut on the lower boss 8 ′ and set bolt (not shown)
Fix with. In addition, in each of the above embodiments, the four-leg stand is used. However, it is more convenient to use the stand with casters.
