せる。To explain the operation of the embodiment of the invention configured as above, first, when the locking device is engaged, as shown by the solid line in FIG. of the torsion coil spring 1 by raising the handle 10 up until it comes into close contact with the engaging member 6.
By rotating counterclockwise around the support shaft 9 against the elastic force of the torsion coil spring 5, the locking pawl 5 is rotated counterclockwise through the link 11 against the elastic force of the torsion coil spring 8. Then, rotate it clockwise about the shaft rod 7 so that the locking pawl 5 does not come into contact with the engaging member 6, and further raise the cargo receiving platform 3 until it becomes almost vertical. By raising the locking claw 5 up to this point, the tip of the locking claw 5 is fitted into the recess 6a of the engaging member 6.
その後、ハンドル10を支軸9を中心にして時計方向に

ロックが終了する。Thereafter, when the handle 10 is rotated clockwise around the support shaft 9, the locking pawl 5 is rotated counterclockwise around the shaft rod 7 via the link 11, and at a point in FIG. As shown by the chain line, when the handle 10 is inserted into the recess 6a of the engagement member 6 and further rotated, the edge of the handle 10 comes into contact with the locking metal fitting 16, as shown in FIG.
The locking pawl 5 reliably engages with the engaging member 6, and the loading platform 3 is completely locked.

ル10が係止金具16に当接する位置までは、ハンドル
10の時計方向の回動に対して係止爪5も時計方向に回
動するようになる。In the middle of closing the loading platform 3, before the edge of the handle 10 comes into contact with the locking metal fitting 16, a straight line ( 4 and 5), link 11 turns over, i.e.
In the figure, the center of the pin 14 is located on the left side with respect to the above-mentioned line XX, but in FIG. 4, the center of the pin 14 is located on the right side with respect to the line XX, From the position where the center of the pin 14 overlaps on the aforementioned X-X line to the position where the handle 10 abuts the locking metal fitting 16, the locking pawl 5 also rotates clockwise as the handle 10 rotates clockwise. I come to do it.

とする。As a result, when a force is applied to the loading platform 3 in the opening direction when the loading platform 3 is in the closed state shown in FIG. The pawl 5 attempts to rotate clockwise around the shaft 7, but the force is transmitted to the handle 10 via the link 11, causing the handle 10 to rotate clockwise around the support shaft 9. try to make it happen.
ところが、該ハンドル10は係止金具16に当接して時
計方向への回動が抑止されているために、前記係止爪5
は回動することなく、荷受台3を閉鎖状態に保持するこ
とができる。However, since the handle 10 comes into contact with the locking metal fitting 16 and is prevented from rotating clockwise, the locking claw 5
can hold the loading platform 3 in a closed state without rotating.

ある。Further, in the above-mentioned embodiment, the handle 10 and the locking pawl 5 are connected via the link 11, and are configured to rotate in mutually opposite directions, so that the recessed portion 6a facing upward is formed. By making it possible to engage the locking pawl 5 into the engagement member 6 by rotating the handle 10 downward, the locking device can be easily installed at a high position relative to the road surface. However, the present invention is not limited to this, and the locking claw 5 may be rotated by directly fixing the handle to the locking claw 5 or the shaft rod 7. ○ As described in detail above, the loading platform locking device according to this invention has a locking claw rotatably provided on the loading platform, and a recess into which the locking claw is fitted, facing upward. This hydraulic cylinder device not only reliably holds the loading platform in an upright position when the loading platform is not in use, but also drives the loading platform up and down. Alternatively, it is possible to reliably prevent the runner from descending relative to the column in the event of oil leakage from hydraulic piping or the like, or due to vibrations caused by running the vehicle.
