The horizontal holding member 30 is stored near both ends of the second cross member 56 of the rear gate 26 when not mounted.
[0041]
Next, the operation of the rear gate device 12 will be described.
[0042]
First, the operation of loading the transported motorcycle 20B on the carrier 14 will be described.
[0043]
The rear gate 26 is normally closed except for loading and unloading operations, and is stored near the rear end 14A of the loading platform 14. Further, the gate slider 18 is held at the upper limit position.
[0044]
First, the operator releases the lock mechanism 58 of the rear gate 26, operates the elevating switch 68 to extend the cylinder mechanism 28, rotates the rear gate 26 backward, and the road plate member 22 and the motorcycle mounting member 52 The rotation of the rear gate 26 is stopped when the rear gate 26 is inclined upward slightly behind the horizontal.
[0045]
Here, the horizontal holding member 30 housed in the rear gate 26 is taken out, and the hooks 30B at both ends are engaged with the hook 34B of the slider 34 and the hook 56A of the rear gate 26.
[0046]
In this state, if the cylinder mechanism 28 is slightly extended until the horizontal holding member 30 is tensioned by operating the elevation switch 68, the road plate member 22 and the motorcycle mounting member 52 are substantially in a horizontal state.
[0047]
Next, the elevation switch 68 is operated, the cylinder mechanism 28 is contracted, the gate slider 18 is slightly raised, and the movable member 42 of the movable stopper mechanism 40 is separated upward from the receiving member 50. Here, the manual lever 48 is operated to retract the distal end portion 42B of the movable member 42 against the urging force of the spring 44. The retracted state of the movable member 42 is maintained by the cam mechanism 46.
[0048]
When the cylinder mechanism 28 is further extended by operating the elevation switch 68 in this state, the gate slider 18 is lowered, and the rear gate 26 is held in a state where the road plate member 22 and the motorcycle mounting member 52 are held in a substantially horizontal posture. Descend. When the gate slider 18 or a part of the rear gate 26 is grounded, the elevating switch 68 is operated to stop the lowering of the rear gate 26. As a result, the road plate member 22 and the motorcycle mounting member 52 come into contact with or close to the ground 24 in a substantially horizontal posture.
[0049]
The operator pushes the transported motorcycle 20B by human power to get on the motorcycle mounted member 52 and places the stand of the transported motorcycle 20B so as to be in contact with the striped steel plate 52A (see FIG. 1). . This operation is easy even when the transported motorcycle 20B is heavy because the motorcycle mounted member 52 is in contact with or in contact with the ground 24 in a substantially horizontal posture.
[0050]
Next, after operating the manual lever 48 to protrude the distal end portion 42B of the movable member 42, the lift switch 68 is operated to contract the cylinder mechanism 28 and raise the gate slider 18.
[0051]
When the distal end portion 42B abuts on the guide rail 16, the movable member 42 is guided by the inner peripheral surface of the guide rail 16 on the side surface and retracts against the urging force of the spring 44, and the gate slider 18 rises to near the upper limit position. Then, the distal end portion 42B of the movable member 42 re-projects. When the slide bar 36 comes into contact with the fixed stopper 38, the elevation switch 68 is operated to stop the elevation.
[0052]
Thereby, the motorcycle mounted member 52 is held in a substantially horizontal state and rises to the vicinity of the rear end floor surface 14B of the carrier 14.
[0053]
Here, the gate slider 18 is slightly lowered by operating the elevation switch 68, and the distal end portion 42 </ b> B of the movable member 42 is brought into contact with the receiving member 50.
[0054]
In this state, the worker pushes the transported motorcycle 20 </ b> B by human power and loads the motorcycle 20 on the loading platform 14 from above the motorcycle mounted member 52. Since the motorcycle mounted member 52 is held in a substantially horizontal state near the rear end floor surface 14C of the loading platform 14, the loading operation is easy even when the transported motorcycle 20B is heavy. Further, the transported motorcycle 20B is mounted at a predetermined position on the carrier 14.
[0055]
Next, the elevation switch 68 is operated to slightly raise the gate slider 18 so that the distal end portion 42B of the movable member 42 is separated upward from the receiving member 50. At this point, the movable member 42 is retracted by operating the manual lever 48, and further, the elevating switch 68 is operated to lower the rear gate 26 until it touches the ground 24.
[0056]
Thereafter, the loading operation of the transported motorcycle 20B is similarly repeated. After all the transported motorcycles 20B are mounted on the carrier 14, the transported motorcycles 20B are fastened to the carrier 14. Further, with the gate slider 18 held at the upper limit position, the gate slider 18 is slightly rotated in the direction of the closed position to move the hooks 30B at both ends of the horizontal holding member 30 from the hook 34B of the slider 34 and the hook 56A of the rear gate 26. Then, the horizontal holding member 30 is stored in a predetermined storage position of the rear gate 26.
[0057]
Further, the elevation switch 68 is operated to rotate the gate slider 18 to the closed position, housed in the rear end 14A of the carrier 14, and fixed to the closed position by the lock mechanism 58.
[0058]
Thereby, the loading operation of the transported motorcycle 20B is completed, and the automobile transport vehicle 10 can run. In the case of unloading, the unloading operation of the transported motorcycle 20B may be performed in the reverse procedure using the horizontal holding and raising and lowering of the motorcycle mounted member 52.
[0059]
The rear gate 26 has a structure in which the motorcycle mounted member 52 is disposed between the two road plate members 22. The motorcycle mounted member 52 is shorter in length than the road plate member 22 and is further expanded. Low aerodynamic resistance due to the structure using metal as the main member. Note that, although a part of the motorcycle mounted member 52 is closed by the striped steel plate 52A, the effect is small since the closed area is limited to a part.
[0060]
Next, the operation of the rear gate device 12 in the loading operation of the transported automobile 20A will be described.
[0061]
The operator first releases the lock mechanism 58 of the rear gate 26 in the closed position, then operates the elevating switch 68 to extend the cylinder mechanism 28, and the wheel 60 of the free end 22 </ b> B of the road plate member 22 touches the ground 24. The rear gate 26 is rotated backward until the rear gate 26 rotates.
[0062]
Next, the auxiliary road plate member 66 is manually turned back and placed on the ground 24 so as to be farthest rearward from the road plate member 22 (to the extent permitted by the elongated hole 64A of the engaging member 64).
[0063]
As shown in FIG. 10, loading and unloading operations are normally performed by the transported automobile 20A running on the auxiliary road plate member 66 and the road plate member 22 in this state.
[0064]
However, as shown in FIG. 11, when the transported four-wheeled vehicle 20 </ b> A is a low-down vehicle, the lower front portion of the vehicle may interfere with the upper surface of the inclined road plate member 22.
[0065]
When loading such a lowdown vehicle, first, the elevation switch 68 is operated to contract the cylinder mechanism 28 to slightly raise the gate slider 18, and the movable member 42 of the movable stopper mechanism 40 is received from the receiving member 50. Separate upward. Further, the user operates the manual lever 48 to hold the distal end portion 42B of the movable member 42 in the retracted state against the urging force of the spring 44.
[0066]
In this state, when the elevation switch 68 is operated to extend the cylinder mechanism 28, the rear gate 26 swings, and the base end 22A of the road plate member 22 is lowered. As the base end 22A descends, the free end 22B moves slightly backward, but can move without sliding on the ground because the wheels 60 roll. Further, since the engaging member 64 has the elongated hole 64A, even if the free end 22B of the road plate member 22 horizontally moves rearward, the auxiliary road plate member 66 does not move rearward in conjunction therewith. .
[0067]
When the base end 22A of the road plate member 22 descends to the vicinity of the ground 24 and the road plate member 22 assumes a substantially horizontal posture, the elevating switch 68 is operated to stop the extension of the cylinder mechanism 28.
[0068]
Next, as shown in FIG. 12, the transported four-wheeled vehicle 20 </ b> A rides on the road plate member 22 from the auxiliary road plate member 66 by self-propelled driving.
[0069]
The road plate member 22 is in a substantially horizontal state, and furthermore, the level difference at the time of entry by the auxiliary road plate member 66 is reduced, so that even if the transported automobile 20A is a low-down vehicle, the lower front end of the vehicle is a road. It is possible to get on without interfering with the upper surface of the plate member 22.
[0070]
Next, the side brake (not shown) of the transported automobile 20A is applied, the manual lever 48 is further operated to cause the distal end portion 42B of the movable member 42 to protrude, and then the elevation switch 68 is operated to operate the cylinder mechanism. When the gate slider 18 is contracted, the gate slider 18 is guided by the guide rail 16 and rises, and the base end 22A of the road plate member 22 also rises.
[0071]
As shown in FIG. 13, when the base end 22A of the road plate member 22 rises, the transported four-wheeled motor vehicle 20A tilts upward and forward with the contact portion between the rear wheel and the auxiliary road plate member 66 as a fulcrum. To rise.
[0072]
When the distal end portion 42B abuts on the guide rail 16, the movable member 42 is guided by the inner peripheral surface of the guide rail 16 on the side surface and retracts against the urging force of the spring 44, and the gate slider 18 rises to near the upper limit position. Then, the distal end portion 42B of the movable member 42 re-projects. When the slide bar 36 comes into contact with the fixed stopper 38, the elevation switch 68 is operated to stop the elevation. The base end 22A of the road plate member 22 rises to near the rear end floor surface 14C of the loading platform 14.
[0073]
Here, the gate slider 18 is slightly lowered by operating the elevation switch 68, and the distal end portion 42 </ b> B of the movable member 42 is brought into contact with the receiving member 50.
[0074]
As the base end 22A of the road plate member 22 rises, the free end 22B of the road plate member 22 moves forward, but the wheel 60 rolls, so that the free end 22B does not slide on the ground. The auxiliary road plate member 66 does not move forward in conjunction with the forward movement of the free end 22B of the road plate member 22 because of having the long hole 64A.
[0075]
After releasing the side brake of the transported automobile 20A, the transported automobile 20A is loaded on the carrier 14 by self-propelled and mounted at a predetermined position on the carrier 14. Since the base end 22A of the road plate member 22 is located near the rear end floor surface 14C of the loading platform 14, the transported four-wheeled motor vehicle 20A can get in without interfering with the loading platform 14.
[0076]
Next, the elevation switch 68 is operated to slightly raise the gate slider 18,
The distal end portion 42B of the movable member 42 is separated from the receiving member 50. In this state, the movable member 42 is retracted by operating the manual lever 48, and further, the elevation switch 68 is operated to lower the base end 22 </ b> A of the road plate member 22 to the vicinity of the ground 24.
[0077]
Thereafter, similarly, the loading operation of the transported automobile 20A is repeated. When all of the transported automobiles 20A have been mounted on the platform 14, the transported automobiles 20A mounted on the platform are secured to the platform 14.
[0078]
Further, in a state where the gate slider 18 is held at the upper limit position, the lift switch 68 is operated to rotate the gate slider 18 to the closed position and housed in the rear end 14 </ b> A of the loading platform 14, and the lock mechanism 58 holds the gate slider 18 at the closed position.
