DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a light truck having a loading platform 2.
At the rear end, a tailgate elevating device 3 used for loading and unloading luggage is provided. The tailgate elevating device 3 is detachable from the loading platform 2 by means described later.

The tailgate elevating device 3 has a gate-shaped tailgate 4 and an elevating table 5 on which a container C containing luggage is placed so as to be able to ascend and descend via an elevating frame 6. The elevating table 5 and the elevating frame 6 are vertically moved by being driven by a motor 7 driven by a battery (not shown) as a power source, and the elevating operation is performed by a control box 8 and an operation switch 9. Also, three upper and lower limit switches 10 are provided in the vertical movement range of the vertical frame 6, and the vertical platform 5 is located at the lowermost position, the height position of the loading platform which is the uppermost position, and any position between them. Are controlled to stop automatically when they are at the position of.

The tailgate elevating device 3 can be moved back and forth with respect to the carrier 2 together with the tailgate elevating device 3, and can be fixed and released by inserting and removing fixing pins 12 at the front end of the carrier 2. -A fixing frame 11 is provided. The tailgate elevating device 3 is attached to the carrier 2 when it is used, and can be removed when it is unnecessary.

The tailgate elevating device 3 is moved by a pair of left and right removably attached to the lower end of the elevating frame 6 so that the elevating table 5 and the elevating frame 6 are lowered to the lowermost position and grounded. The caster 14 and a pair of left and right casters 14 respectively attached to the lower end of a moving auxiliary arm 13 which is detachably provided on the left and right sides of the distal end of the moving / fixing frame 11, move forward and backward with respect to the carrier 2. By moving, the tip of the moving / fixing frame 11 is attached to and detached from the carrier 2 by inserting and removing the fixing pins 12.

The tailgate lifting / lowering device 3 having such a configuration.
In order to load the container C containing the luggage on the bed 2 of the light truck or to unload the container C loaded on the bed 2, the tailgate elevating device 3 is moved by four casters 14 as shown in FIG. The moving / fixing frame 11 is fitted to the carrier 2 by being moved, and the fixing pins 12 are inserted between the tip of the moving / fixing frame 11 and the carrier 2 to be fixed. Thereafter, the moving auxiliary arm 13 is removed together with the casters 14, and the casters 14 at the lower end of the elevating frame 6 are also removed to bring them into the use state shown in FIG.

When the container C is loaded on the loading platform 2, the operation switch 9 is operated to lower the lifting platform 5 to the lowermost position, that is, the grounding position, and the container C is loaded on the lifting platform 5; The lifting platform 5 is raised by the operation, raised to the same height as the loading platform 2 and stopped, and the container C is loaded on the loading platform 2. The labor required for the worker to perform the loading operation by conventionally lifting the container C from the ground to the height of the loading platform 2 or higher is greatly reduced.

When lowering the container C loaded on the loading platform 2 to the ground, the lifting platform 5 is lifted, raised to the same height as the loading platform 2 and stopped, and the container C on the loading platform 2 is placed on the lifting platform 5. And lift platform 5 down to the ground,
To the ground. Further, the container C on the carrier 2 may be transferred to a carrier of another carrier.

When it is not necessary to load the container C on the loading platform 2 of the light truck 1 or to unload the container C loaded on the loading platform 2, that is, when the tailgate lifting / lowering device 3 is not required, the fixing pins 12 are removed. Move
The connection between the tip of the fixing frame 11 and the carrier 2 is released, and the moving auxiliary arm 13 is attached to the moving / fixing frame 11.
And the tailgate elevating device 3 is moved with the caster 14 attached to the lower end of the elevating frame 6, removed in the state of FIG. 2 and the light truck 1 is mounted without the tailgate elevating device 3. use.

[0018]

As described above, according to the tailgate lifting / lowering device for a transport vehicle of the present invention, the following effects can be obtained.

[0019] The tailgate elevating device has a frame that can be fixed to and released from the loading platform. It can be attached to the loading platform when the tailgate lifting device is used, and can be removed when unnecessary. The device can be easily and easily attached to the carrier of the transport vehicle used and used to load and unload cargo. In addition, when the tailgate elevating device is not required, it can be easily and easily removed, so that no load is imposed on the traveling vehicle.

[0020] Since the tailgate lifting device is provided with moving wheels, it is moved back and forth with respect to the loading platform, and the frame attached to the tailgate lifting device is attached to and detached from the loading platform,
When the tailgate lifting / lowering device is attached to / detached from the carrier of the transport vehicle, the tailgate lifting / lowering device can be moved back and forth by the moving wheels, so that the tailgate lifting / lowering device can be fitted to and removed from the carrier in a short time.
