FIGS. 5 and 6 are re-spectively plan views showing essential parts of the present invention; and FIG. 7 is a sectional view showing a conventional example.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be described in detail in connection with embodiments shown in the drawings.
In ~IGS. 1 and 2, reference numeral 1 designates a level for a vertical collimator for a head lamp (herein-after referred to as level 1). This level 1 is to measure level by the bubble tube 2 similarly to the conventional example but in the present invention, the bubble tube 2 is mounted on a sub-base 3, and the sub-base 3 is mounted on a main bed 6 through a setting elevating portion 4 and an adjusting elevating portion 5.
,, , ~

The setting elevating portion 4 is provided so that one end on the detection side of the bubble tube 2 mounted on the sub-bed 3 may be moved up and down, and is composed of an adjusting screw 4a which extends through the sub~bed 3 and is threadedly mounted on the main bed 6, and a coil spring 4b in a compressed state held between the sub-bed 3 and main bed 6.
The adjusting elevating portion 5 has a structure approximately similar to the former and is provided on the other end on the detection side of the bubble tube 2.
An adjusting screw Sa is provided with a display portion 7 whose head is enlarged into a disk-like configuration and on which graduations are provided.
FIG. 3 shows the operation and effect of the level 1 constructed as described above. When the level 1 is used for the purpose of measuri~g.~ levelness of a ground level on which an automobile is placed and at a position in which the main bed 6 is mounted, for example, a housing for a head lamp is not horizontal, the adjusting screw 5a of the adjusting elevating portion 5 is rotated in a suitable direction so that the display portion 7 is placed i.n registration with 'O'.
In this condition, the bubble tube 2 does not naturally display level. Therefore, the adjusting screw 4a of the setting elevating portion 4 is rotated in a ' ~, , suitable direction till the bubble tube 2 indicates level.
With the aforementioned arrangement, the l.evel 1 indicates levelness of the ground level irrespective of an inclination of a location in which the main bed 6 is mounted, thus achieving the object.
FIG. 4 shows a second embodiment of the present invention In the previous embodiment, the sub-bed 3 and the main bed 6 are mounted by two elevating portions, the setting elevating portion 4 and the adjusting elevating portion 5. On the other hand, in the second embodiment, one end of the bubble tube 2 of the sub-bed 3 of the level 11 is supported, for example, by a shaft 8 so as to change an inclination in a direction of sensitivity of the bubble tube 2, and in the adjusting elevating portion 5 provided on the other end thereof, an adjusting screw 15a and a disk-like display portion 17 are divisionally formed so that rotation and fixation of the display portion 17 to the adjusting screw 15a may be freely made.
In the level 11 constructed as described above, under the mounting condition similar to that as described in the previous embodiment, fixation be~.ween the adjusting screw 15a and the display portion 17 is first re].eased, under which condition9 adjustment of the adjusting screw 15a is made so as to cause the bubble tube 2 to indicate level, and thereafter the display portion i7 is fixed so that the -: ~

display portion 17 indicates lol.
FIGS. 5 and 6 show means for causing the level 1 or 11 to display a degree of inclination which constitutes another subject matter of the present invention. In FIG.
5, the bubble tube 2 is provided with graduations every 0.2, for example, in positive and negative directions other than graduations indicative of level, and a degree of inclination can be read merely by observing the bubble tube 2. In FIG. 6, the bubble tube 2 is merely provided with graduations indicative of level, and the display portions 7, 17 are provided with graduations every 0.2, for example.
The adjusting screws 5a and 15a are rotated ln a suitable direc~ion to cause the bubble tube 2 to indicate level, and a displacement from the '0' posltion of the display portions 7 and 17 is read so as not to read a degree of inclination, whereby when the level 1 is used as a colli-matorfor a head lamp, judgement of a deviation or decision of amount and direction of adjustment may be easily made to improve workability.
It is to be noted that the display means shown in ~IGS. 5 and 6 may be combined with either first or second embodiment as described above.
As described above, the bubble tube oE the level is mounted on the sub-bed, and the sub-bed and the main bed may be inclined in displaying a predetermined value .: '.: ' ' , ~ : :
