Description

[Detailed Description of the Invention] This invention relates to a loading platform for a transport vehicle or the like, in which side plates can be fixed vertically or horizontally to a bottom plate.

The loading platform of a lumber carrier, etc. must be loaded with a load that is longer than the length of the loading platform, so the rear side plate is moved from its normal position perpendicular to the bottom plate to a horizontal position where it falls backwards and becomes flush with the bottom plate. It is now possible to change the fixed state. For this reason, conventionally, connecting rods protruding from the rear side plate are provided at both ends of the rear side plate in contact with the bottom plate, and these connecting rods are fitted into vertical or horizontal guide frames provided on the bottom plate side and then bolted. There was a loading platform with a rear side plate that was removably fixed. However, in a cargo platform with such a structure, a tool is required to remove the bolts each time the fixed position of the rear side plate is changed, and in addition, the heavy rear side plate must be manually supported while the connecting rods are removed. The work was cumbersome because it had to be pulled out from the guide frame and fitted into the other guide frame.

This idea was developed in view of the above circumstances, and it supports the movement of the side plate when the connecting rod is pulled out from one guide frame and then fitted into the other guide frame, and also supports the movement of the connecting rod when the connecting rod is inserted into the other guide frame. By providing a side plate support that can fix the movement of the side plate when fitted into the guide frame, tools are not required when changing the fixing position of the side plate.
Moreover, it is an object of the present invention to provide a loading platform for a transport vehicle or the like that is easy to work with.

An embodiment of this invention will be described based on the drawings. In Figure 1, a loading platform 1 for a transport vehicle etc. is attached to a rear side plate 2.
The case where the can be fixed vertically or horizontally is shown. The rear side plate 2 consists of a frame made of square timber, and the bottom plate 3
The end portions of the frame body, which are both ends on the side in contact with, respectively protrude to form a connecting rod 4. The bottom plate 3 is provided with vertical and horizontal guide frames 5 and 6, respectively, at both rear ends thereof, into which the connecting rod 4 is fitted. The vertical guide frame 5 holds the rear side plate 2 in the vertical direction with respect to the bottom plate 3 by fitting the connecting rod 4 therein, and the horizontal guide frame 6 holds the rear side plate 2 vertically with respect to the bottom plate 3 by fitting the connecting rod 4 thereinto. 2 is held horizontally with respect to the bottom plate 2. The side plate support 7 consists of a side plate bracket 8, a bottom plate bracket 9, and a set shaft 10, as shown in FIGS. 2-5. The side plate bracket 8 is connected to the connecting rod 4 of the rear side plate 2.
The bottom plate bracket 9 is provided at the rear end of the bottom plate 3 and at a corresponding position inside the two bottom plate brackets 8 so as to project therefrom. The set shaft 10 has a handle 11 at one end.
A stopper 13 is provided to adjustably limit the length of the shaft portion 12 by screwing a double nut into a threaded portion formed at the other end.
The bottom plate bracket 9 is provided with a bearing 14 in the direction of the rotation center axis when the rear side plate 2 moves from the vertical direction to the horizontal direction. The shaft portion 12 of the set shaft 10 is rotatably and slidably fitted into this bearing 14 with the handle 11 facing inward, so that the stopper 13 side of the shaft portion 10 can protrude outward. . Further, on the handle 11 side, which is the inside of the bottom plate bracket 9, there is provided a protrusion 15 that protrudes downward further inward than the end face of the bearing 14, and when the handle 11 is rotated downward and is engaged with this protrusion 15, the shaft portion 12 The outward protrusion is returned by the protrusion of the protrusion 15. The side plate bracket 8 has an elongated hole 1 in which the bearing position can slide.
6 is provided, and this elongated hole 16 is fitted into the shaft portion 12 of the set shaft 10 protruding from the bottom plate bracket 9. This elongated hole 16 is provided in a direction such that the bearing position moves parallel to the connecting rod 4, and
When fitted into the vertical or horizontal guide frames 5, 6, the bearing position of the fitted set shaft 10 is adjusted to be the position closest to the rear side plate 2 of this elongated hole 16. By sliding the bearing position of the set shaft 10 toward the end of the connecting rod 4, rotating it, and returning it to its original position, the connecting rod 4 can be moved to one of the guide frames 5.
Alternatively, the hole has a length such that it can be pulled out from the guide frame 6 or rotated 90 degrees and fitted into the other guide frame 6 or 5. Further, on the outer end surface of the elongated hole 16 where the stopper 13 engages, only the bearing position closest to the rear side plate 2 is recessed inward to form a step 17, and when the set shaft 10 is in this recessed bearing position, Rotate the handle 11 downward until the protrusion 15
It is designed so that it can be locked.

When the loading platform 1 of the transport vehicle or the like of this invention constructed as described above is used with the rear side plate 2 in a vertical position, as shown in FIGS. 2 and 3, the handle of the set shaft 10 is Rotate 11 downward and remove protrusion 1
5, the stopper 1 of the set shaft 10
3 is blocked by the step 17 of the side plate bracket 8, there is no fear that the connecting rod 4 fitted into the vertical guide frame 5 will come off, and the rear side plate 2 is fixed vertically. When using the rear side plate 2 in a horizontal position, first rotate the handle 11 of the set shaft 10 upward to release the latch of the protrusion 15, as shown in FIGS. 4 and 5. Te, Stoppa 13
Push it out so that it protrudes outward, and stopper 1
3 is no longer blocked by the stage 17, and the bearing position on the elongated hole 16 of the set shaft 10 can be moved. Therefore, as shown in Figs. 6 to 8, the rear side plate 2 is pulled upward, the connecting rod 4 is pulled out from the vertical guide frame 5, and the rear side plate 2 is rotated 90 degrees at the bearing position of the set shaft 10 at that time. and push the rear side plate 2 forward to move the connecting rod 4 into the horizontal guide frame 6.
It can be inserted into. Then, rotate the handle 11 of the set shaft 10 downward again to remove the protrusion 15.
By locking the rear side plate 2, the rear side plate 2 can be fixed horizontally.

As explained above, when changing the fixing position of the rear side plate 2 of the loading platform of a transport vehicle or the like of this invention, the fixation can be released by simply rotating the handle 11 of the set shaft 10, so no tools are required. Moreover, when the rear side plate 2 is pulled up, rotated, and pushed in, the side plate bracket 8 is attached to the shaft portion 12 of the set shaft 10.
Since the elongated hole 16 is supported for rotation and sliding, the work becomes easier.

This invention is not limited to the rear side plate 2 of the loading platform 1, but can also be applied to both side plates and, if necessary, to the front side plate.
