FIG. 5 is a diagram showing a method of storing a truck using the truck lifting device, and FIG. 6 is a diagram showing the movement of the hook hook 16 and the rear wheel in the truck climbing the truck lifting device. In addition, "*" in FIG. 5 indicates the handle of the operator in that state.
When the truck 10 is stored, first, the additional slope 90 of the truck lifting device 20 is rotated to be in the unfolded state.
Next, the connector 53 of the vehicle locking body 50 is removed from the connection receiver 2A, and the slope 30 is tilted downward. In this state, the rear end of the additional slope 90 and the intermediate portion of the extending portion 52 of the vehicle locking body 50 where the footboard 100 is provided are in contact with the ground.

Next, as shown in FIG. 5( a ), the operating handle 14 of the truck 10 is held, the front wheels 11 of the truck 10 are put on the additional slope 90 side, and pushed up along the slope 30 . As described above, the additional slope 90 has a guide shape whose width gradually narrows toward the second slope portion 30B, and the additional slope wall portion 91 is provided at the side end. Guided by the slope 90, the user can smoothly reach the second slope portion 30B.
In addition, since the trolley 10 placed on the slope 30 is in a state in which the second slope portion 30B is lightly sandwiched from both sides by the clamping portions 17, this suppresses the trolley 10 from wobbling left and right while traveling on the slope 30, You can proceed with the storage work safely. In addition, since the distance between the left rear wheel 12 and the right rear wheel 13 of the truck 10 is larger than the width of the additional slope 90 and the slope 30, the rear wheels 12 and 13 do not ride on the slope 30, and the rear wheels 12 and 13 do not ride on the slope 30 at least until the footboard 100 is crossed. rolls on the ground.

As shown in FIG. 5(b), as the height difference between the front wheels 11 and the rear wheels 12 and 13 of the cart 10 being pushed up gradually increases, the hook hooking portion 16 faces slightly upward from the horizontal. . When the front wheel 11 reaches the front end side of the second slope portion 30B, the rear wheel starts to ride on the footboard 100. - 特許庁As a result, the rear wheels of the carriage 10 are lifted, and the inclination of the carriage 10 is slightly moderated.
As shown in FIG. 5(c), when the carriage 10 is further advanced, the hook hooking portion 16 approaches the front hook 70. As shown in FIG. At this time, the rear wheels reach the top of the footboard 100, so that the rear wheels of the truck 10 are further lifted, and the inclination of the truck 10 becomes slightly gentler. Therefore, the hook hooking portion 16 is oriented more horizontally than in the state shown in FIG.
As shown in FIG. 5(d), the carriage 10 is advanced further, the rear wheels 12 and 13 begin to descend from the footboard 100, and the front wheels 11 advance to the first slope portion 30A, which is steeper than the second slope portion 30B. Then, the carriage 10 is steeply tilted, and the hook hooking portion 16 rotates in the vertical direction and is received by the upper front hook 70 (see FIG. 6). In this way, when the hook hooking part 16 approaches the front hook 70, the rear wheel rides over the footboard 100, so that the hook hooking part 16 naturally slips into the front hook 70 from below and is easily engaged. be able to.
When the hook hooking portion 16 and the front hook 70 are engaged with each other, the carriage 10 will not move backward even if the operator releases the operating handle 14.例文帳に追加Further, as described above, the front hook 70 is provided with the protective material 72 between the pair of key claws 71 . As a result, the contact area between the front hook 70 and the hook hooking portion 16 is increased compared to when the protective material 72 is not provided, and the hook hooking portion 16 is less likely to be damaged.

Next, as shown in FIG. 5( e ), the operator holds the handle 92 of the additional slope 90 and lifts the slope 30 .
When the hook hooking portion 16 is engaged with the front hook 70 , the front wheel 11 of the truck 10 is on the first slope portion 30A ahead of the weight hinge 60 . Therefore, when the slope 30 is lifted, the force of the front wheel 11 pushing the first slope portion 30A downward increases due to the moment balance. As a result, the operator's operating force is reduced, and it can be easily lifted.
Further, by providing the handle 92 on the additional slope 90 instead of the second slope portion 30B, the distance from the fulcrum (weight hinge 60) to the handle 92 increases, and the slope 30 can be lifted more easily by the principle of leverage. , the burden on workers can be reduced.
The operator connects the connector 53 of the vehicle locking body 50 to the connection receiver 2A while the slope 30 is lifted. Thereby, the truck 10 is held substantially horizontally. Therefore, it is possible to store the cart 10 while the hose container containing the fire hose and the materials and equipment such as the portable pump are placed on the carrier 15 .
Then, as shown in FIG. 5(f), the additional slope 90 is rotated downward to be in the retracted state. By setting the storage state, the additional slope 90 does not protrude from the rear end of the vehicle, and the slope 30 can be stored in the storage room 2.例文帳に追加

FIG. 7 is a diagram showing a method of deploying a truck using a truck lifting device. In addition, "*" in FIG. 7 indicates the handle of the operator in that state.
When deploying the carriage 10, first, as shown in FIG. 7(b), the additional slope 90 of the carriage lifting device 20 is rotated from the state shown in FIG. 7(a) to the deployed state.
Next, as shown in FIG. 7(c), the connector 53 of the vehicle locking body 50 is removed from the connection receiver 2A, and the slope 30 is tilted downward. In this state, the rear end of the additional slope 90 and the intermediate portion of the extending portion 52 of the vehicle locking body 50 where the footboard 100 is provided are in contact with the ground.
Next, as shown in FIG. 7(d), the operation handle 14 of the truck 10 is held, the rear wheels 12 and 13 of the truck 10 are slightly lifted, and the hook hooks 16 are removed from the front hooks 70. Then, as shown in FIG.
Then, as shown in FIGS. 7(e) and 7(f), the carriage 10 is pulled out rearward along the slope 30 . Since the trolley 10 placed on the slope 30 as described above is in a state in which the second slope portion 30B is lightly sandwiched from both sides by the clamping portions 17, the trolley 10 that is retreating on the slope 30 is suppressed from wobbling from side to side, can be safely deployed.

Thus, by using the trolley lifting device 20 of the present invention, even a heavy trolley 10 weighing several tens of kg or more can be loaded and unloaded from the vehicle by one person.
