Figures 1(A)-(C) and FIGS. 2(A) to 2(C) are explanatory diagrams of the operation of the freight vehicle according to the embodiment of the present invention. Figures 1 and 2 , 1 is the chassis frame, 2 is the subframe, 3 is the lift frame, and 5 is the The body 6 is a guide rail consisting of a channel. With the chassis frame 1 above The subframe 2 constitutes the vehicle body. The lift frame 3 above is tilted toward the rear end. It has a bent portion 9 bent downward. Further, the guide rail 6 is connected to the sub-assembly. It has a front part lower than the frame 2 and a rear part higher than the subframe 2.

0010 The lift frame 3 rolls in the groove of the guide rail 6 consisting of the channel. When sliding from the front to the rear, the rollers 10 and stays 14 move backward. When it tilts and slides from the back to the front, it becomes horizontal. Ma In addition, the lift frame 3 slides along guide rollers 7 provided at the rear of the vehicle body. It is now possible to The lower end of the bent portion 9 at the rear end of the lift frame 3 is As shown in Figure 1(C), slide the lift frame 3 backward as much as possible and tilt it. When it is in the up position, it is almost in contact with the ground. And as shown in Figure 3 A slide cylinder whose tip is pivotally connected to a shaft 11 that pivotally supports the roller 10. The tube of the frame 12 is pivotally connected to the subframe 2. And on shaft 11 The stay 14 is attached. The slide cylinder 12 above is a lift frame 3 serves as a lift frame drive means for sliding the frame in the front and back direction.

[0011] The body 5 slides on the lift frame 3 with the structure shown in FIG. That's what I do. That is, one end is fixed to the front end of the lift frame 3, and the other end is fixed to the front end of the lift frame 3. A chain 19 fixed to the rear end of the lift frame 3 is attached to the front end of the body 5. A driving sprocket 18 provided on the body 5 and an idler 20 pivotally supported on the body 5, It is wound around 21. The sprocket 18 is fixed to the drive shaft 23. Ru. Further, the pair of idlers 20 and 21 are swingably attached to the drive shaft 23. It is attached to a bracket 38 that is attached. The sprocket 18 is A hydraulic motor (not shown) fixed to the drive shaft 23 drives the drive shaft 23. is driven. Therefore, the sprocket 18 is driven by the hydraulic motor. By running the chain along the chain 19, the lift frame including the bent part 9 is removed. The body 5 can slide over the entirety of the room 3. At the bend 9 A bracket 38 to which a pair of idlers 20 and 21 are attached swings along the Thus, the body 5 can smoothly slide on the bending portion 9. Above sprocket 1 8, idlers 20, 21, chain 19, and the above hydraulic motor etc. to drive the body. constitutes a means.

0012 Further, as shown in FIGS. 1 and 2, a roller 29 is provided at the rear end of the body 5. Ru.

[0013] The freight vehicle having the above configuration is loaded with cargo, such as a car, as follows.

[0014] First, assuming that this truck is in the state shown in Figure 1(A), the slide cylinder 12 and slide the lift frame 3 backward along the subframe 2. let Then, the lift frame 3 slides backward along the guide rail 6. to tilt the lift frame 3 backward by lifting the front side of the lift frame 3. The state shown in FIG. 1(B) is then changed to the state shown in FIG. 1(C).

[0015] Next, the hydraulic motor fixed to the body 5 is driven, and the hydraulic motor installed at the front end of the body 5 is driven. A chain 1 in which a driving sprocket 18 is stretched along a lift frame 3. 9, as shown in Figures 2(A),(B),(C), Move the body 5 together with the proket 18, bracket 38, etc. along the lift frame 3. Slide it backwards. A pair of idlers 20, 2 are installed along the bending portion 9. The bracket 38 to which the body 5 is attached swings, and the front end of the body 5 smoothly moves into the above position. It can descend along the bend 9. At this time, the roller 29 at the rear end of the body 5 is on the ground. The body 5 is smoothly retreated from the ground by touching the ground.

[0016] When the body 5 is lowered the most along the bending part 9 of the lift frame 3, the The situation will be as shown in (C). In this state, body 5 is lowered almost horizontally to the ground. It is. Then, a car is loaded onto body 5. The body 5 is compared to the case where the rear end of the lift frame 3 is not bent. , the total length when the body 5 is lowered can be shortened.

[0017] In this way, in order to load the car onto the almost horizontal body 5, the driver The car moves forward until it reaches the front edge of body 5 without any sense of anxiety. This allows the car to be easily mounted on the body. In addition, the driver automatically When getting out of the car, there is no danger as the body 5 is almost horizontal on the ground. The driver can get out of the car at any time. In addition, automobiles or other When loading and securing cargo onto this horizontal body, the body 5 must be in a horizontal position. This makes it easy to secure the baggage, and there is no fear of the baggage coming loose. In addition, since cargo is loaded onto the horizontal body, it can be loaded not only from the rear but also from the side. Even cargo can be easily loaded onto the body 5.

[0018] Next, the hydraulic motor fixed to the body 5 is driven to drive the sprocket 18 and the chain. The body 5 is first raised along the bending part 9 via the horn 19, and then the lift frame is raised. slide it forward along beam 3. At this time, the weight of the car lifts the car. The lower end of the bent portion 9 of the frame 3 is in contact with the ground, and the bent portion 9 of the lift frame 3 is supported. It acts as a member and prevents the vehicle from rolling backwards.

[0019] After the body 5 is sufficiently advanced onto the lift frame 3, the slide cylinder 12 Extend the lift frame 3 and slide the guide rail 6 forward. lower the front side of the lift frame 3 to return the lift frame 3 to a horizontal state. 1(A).

[0020] In the above embodiment, the body 5 was lowered almost horizontally to the ground, but the lift frame 3 A stopper or the like for the body 5 is provided on the bent portion 9 of the body 5, and the body 5 may be stopped in the middle of the bent portion 9. In this case, the luggage is attached to the body. The overall length of the truck during loading can be shortened due to the presence of the bent portion 9. In addition to this effect, it can be made even shorter.

[0021] Further, as shown in FIG. 5(B), the floor surface of the body may be tapered. this In this case, the overall length of the truck can be shortened when cargo is loaded onto the body.

[0022]

[Effect of the idea]

As is clear from the above explanation, the freight vehicle of the present invention is driven by a lift frame. means to slide the lift frame rearward and Slide the front guided part of the arm along the guide rail where the rear part is raised, and Tilt the lift frame backwards and drive the body onto this lift frame. The body is slid by the moving means and lowered along the bend, until the body is almost on the ground. Either lower it horizontally or bring the body close to horizontal to the ground. Therefore, cargo can be loaded onto the body which is in a nearly horizontal position.

[0023] Therefore, according to this invention, luggage can be easily loaded onto the vehicle body. In both cases, the driver does not have to worry at all because the vehicle can be placed on a nearly horizontal body. You can easily place the vehicle on the body without feeling uncomfortable, and the front end of the body The vehicle can be moved forward to the limit. Also, if the driver is on the body of the vehicle, When disembarking, the body is placed almost horizontally on the ground, so there is no risk of any danger. There is no fault. In addition, since you only need to secure the cargo to the body in a nearly horizontal position, you can easily secure it. It can be done easily. Also, place the body close to horizontal on the ground. This makes it easy to load cargo from the side.

[0024] Also, since the body is lowered along the bend of the lift frame, the lift Compared to when the rear end of the frame is not bent, the overall length when the body is lowered is It can be made shorter. Then, by simply bringing the body close to horizontal to the ground, When stopping the front end of the lift frame in the middle of the bend of the lift frame, the load should be The overall length when loaded onto a vehicle can be further shortened.
