リフターを装着し、それによって、荷役作業の省力化、
迅速化を図ったものが知られている。Generally, in a freight vehicle, cargo is loaded and unloaded between the ground and the vehicle's loading platform by vertically raising and lowering a gate member held horizontally at the rear of the truck's loading platform, and when not in use, the gate A gate lifter is installed that makes the member stand up almost vertically and uses the gate member as a tailgate, thereby saving labor in cargo handling work.
There are known methods that are designed to speed up the process.
ところが、大型車両に装着するゲートリフターでは、そ
のゲート部材の重量が大きくなり、手動による起倒操作
が困難になるという不具合があった。However, gate lifters installed on large vehicles have a problem in that the weight of the gate member becomes large, making it difficult to raise and lower the gate manually.
本考案はかかる点に鑑みてなされたもので、簡単な構造
でもって、ゲート部材の起倒動作が確実にかつ安全に行

部材７の昇降が行われる。In FIG. 1, reference numeral 1 denotes a gate lifter, and a pair of guide columns 6 are installed on the left and right sides of the rear of the loading platform of a vehicle 2 along the sides of the loading platform, and a runner 4 is installed in the guiding columns 6.
A gate member 7, which is substantially horizontal in the open state, is rotatably attached to the lower end of the runner 4 via a bracket 5.6. Reference numeral 8 denotes a wire with one end fixed to the upper end of the runner 4, and the other end connected to a hydraulic cylinder (not shown) disposed laterally between the lower ends of both in-house supports O via an upper pulley 9 and a lower pulley 10. (omitted). The gate member 7 is raised and lowered by the operation of the rear hydraulic cylinder.

。Further, an upper roller 11, a middle roller 12, and a lower roller 13 are each rotatably pivotally attached to the runner 4, and are configured to assist the vertical movement of the runner 4. The lower roller 13 prevents the runner 4 from being pressed against the guide column B due to the backward force generated on the runner 4 when the gate member 7 is automatically raised, and also prevents the launch 4 from being pressed against the guide post B due to an overload applied to the front side. It also acts as an auxiliary roller when the roller is bent.

The stopper pieces 22 and 23 are fixed to the vehicle 2 in a substantially horizontal direction, and are constantly biased to rotate in the input direction by the plate members 14a and 15a, and have locking pieces 18c and 19c protruding from the plate members 14a and 15a. The rotation range of the locking piece 18C119c, that is, the hook member 18.19, is restricted by a stop port 26 (only the left side is shown) screwed onto a substantially vertical member 24.25.

れがないからである。With the above configuration, in order to carry out cargo handling work with the gate member 7 substantially horizontal, as shown in FIG.
This can be done by bringing the locking piece 18c into contact with the head of the stop bolt 26 (the same applies to the right hook member 19). In this state, the hook members 18, 19 are connected to the engagement pins 14C%15C! of the arm members 14.15. This is because there is no risk of it being consistent.

いるので、ゲート部材７は起立位置に固縛される。In order to automatically raise the gate member 7 after the cargo handling operation is completed, the arm members 14 and 15 are first rotated forward to the position B shown in chain lines in FIG. In this state, when the gate member 7 is raised, the retaining pins 14C, 15C of the arm members 14.15! first engages with the notches 18a, 19a of the hook member 18, 19, and then the retaining pin 14C
115c is guided through the notches 18a and 19a and is secured to the rete hook portions 18b and 19b (see chain line C in FIG. 2). Furthermore, when the gate member 7 is raised, the hook member 18.
19 (springs 20, 21) arm member 14
．． 15, that is, the upward displacement of the gate member 7 is determined by the shaft 16.
The left arm member 14 side end of is located at the lower end of the elongated hole 7a,
Since the hook portions 18b, 19b of the hook members 1B, 19 are engaged with the engagement pins 14c, 15c of the arm members 14.15, the gate member 7 is secured in the upright position.
