On the outer surface of the position, a large diameter shaft piece 18 having a threaded portion 17 at the tip is projected and a large diameter and slightly longer than the thickness of the column 5 are protrudingly provided. The received receiving member 2 is interposed between the upper portions of the left and right columns 5 and 5 of the column member 1 and a mounting bracket 2 provided at the left and right rear ends thereof.
As shown in FIG. 3, reference numeral 0 is rotatably attached to a mounting bracket 9 provided on the columns 5, 5 by a pivot shaft 21 composed of bolts and nuts.

In this embodiment, a turn buckle mechanism is shown as the angle adjusting mechanism 3. The turn buckle mechanism has an operation hole 21 at the center and a screw hole having a different helical direction at both ends as is well known. With the operation part piece 22 which had,
The angle adjusting mechanism is composed of a pair of connecting pieces 25 and 26 having screw shafts 23 and 24 having different helical directions respectively screwed into screw holes at both ends of the operation piece 22. 3 is rotatably connected to a support fitting 8 provided at the upper end of the support column 5 via a pivot shaft 27, and the other end of the other connecting piece 26 is received. Screw portion 17 of shaft piece 18 of support shaft 19 provided on member 2
The nut 28 is screwed onto the nut so as to be rotatably pivoted.

FIG. 6 is an exploded perspective view of a mounting means 4 for mounting the support member 1 to a protective partition member 45 installed on the back of the driver's seat box 42.
An attachment plate 31 erected on the horizontal rail 6 provided on the support member 1 and having a horizontally long through hole 30 in the center, a U-shaped bend, a threaded part 32 at both ends, and a vertical rail of the partition member 45. A holding nut 33 whose both ends are inserted into the through hole 30 and a lock nut 35 which is screwed to the screw portion 32 via a washer 34 so as to hold the holding member 44 with the mounting plate 31. The mounting means 4 is provided at each position of the horizontal beam 6 intersecting with the vertical beam 44 of the partition member 55 when the support member 1 stands upright on the front portion of the loading platform 41.

In use, as shown in FIGS. 9 and 10, a pillar member is provided at the front of the loading platform 41 so as to overlap with a partition member 45 provided on the back of the driver's seat box 42 of the light truck 40. 1 and the mounting means 4
The support member 5 is mounted on the partition member 45 by the above operation.

In this case, the height position of the column member 1 is adjusted by rotating the rotating operation piece 12 in the height adjusting mechanism 7.

The inclination angle of the receiving member 2 is adjusted by the angle adjusting mechanism 3 in accordance with the length of the long object P loaded on the light truck 40. That is, the operation rod is inserted into the operation hole 21 in the state shown in FIG.
9 to adjust the distance between the long object P and the loading platform 5 as shown in FIG.
1 is set to an angle that can match the inclination angle α of the long object P.

As described above, it is necessary that the rear end of the long object P is engaged with the rear end corner of the loading platform 51 and the front portion of the long object P is supported on the surface of the receiving member 2. The long object P is bound to the receiving member 2 by a rope or the like so as not to collapse as in the related art.

In the above, when the long object P is not loaded and not used, the nut part 28 is connected to the thread part 1 of the shaft piece 18.
7, and after removing one connecting piece 26 of the angle adjusting mechanism 3 from the shaft piece 18, the receiving member 2 is rotated clockwise in the drawing from the state of the imaginary line shown in FIG. Then, as shown by the solid line in FIG. 8, the support shaft 19 abuts on the rear surface of the column 5, and the receiving member 2 comes into contact with the cross bar 6, the receiving member 2 overlaps the rear surface of the column member 1, and the angle is adjusted. The mechanism 3 hangs down around the pivot pin 27 as a fulcrum, and overlaps the outer surface of the column 5 and is folded flat.

[0017]

As described above, according to the present invention, when a long object longer than the entire length of the carrier is loaded on a light truck, the front of the long object protruding toward the upper part of the ceiling of the driver's seat box of the light truck. Because the part is supported on the receiving member surface in a superposed state,
It is possible to maintain a stable loading state and also to maintain operational safety without being affected by vertical vibration of a long object as in the related art even in an operating state. Further, there is an advantage that the mounting means can easily perform the mounting and dismounting operations of the support member on the light truck.

According to the second and sixth aspects of the present invention, when the one end of the angle adjusting mechanism is removed from the receiving member when not in use, the receiving member and the angle adjusting mechanism can be folded flat with respect to the support member. You can do it without getting in the way.

According to the third aspect of the present invention, the height of the support member can be conveniently adjusted according to the length of the long object or the height of the driver's seat box.

According to the structure of the fifth aspect, it is convenient to remove the angle adjusting mechanism, and according to the structure of the seventh aspect, the support member can be securely and stably mounted on the light truck. . Further, according to the configuration of the eighth aspect, there is an advantage that the height adjustment operation can be easily performed.
