Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a loading platform for a truck, and particularly to a loading platform suitable for loading long materials.

[Prior Art and its Problems] When loading long materials such as steel materials and lumber, battens have traditionally been placed on the floor of the loading platform. FIG. 4 shows a side view of a conventional truck loaded with such long materials A. Battens 43 are placed on the floor surface 42 of the loading platform 41 of the truck 40 at predetermined intervals, and the long materials A are stacked on the battens 43 in a stacked state. The batten 43 is used to insert the fork of a forklift when loading or unloading the long material A onto or off the loading platform 41 using a forklift or the like. The long materials loaded in this manner are wrapped around ropes to prevent the cargo from collapsing, and then transported to the destination.

However, the batten 43 is
2 at predetermined intervals, and the long material A is the batten 4.
3, the supporting area is small and the loading condition is unstable. Furthermore, even though the load of the entire cargo is applied to the long material at the lowest tier, the support thereof is performed by the batten 43, so that an excessive load acts on the part where the batten 43 contacts.
Therefore, there is a problem in that the portion of the lowermost elongated material in contact with the batten 43 is dented, damaged, or even deformed due to long-term loading.

SUMMARY OF THE INVENTION An object of the present invention is to provide a truck platform that allows long materials to be loaded stably and without damage.

[Means for Solving the Problems] In order to achieve the above object, the present invention is provided with a support arm that supports at least one end of the long material and is movable up and down on the floor surface on which the long material is loaded. It is characterized by the presence of

[Function] Since the present invention is constructed as described above, the support arm supports the long material so that there is a gap between it and the floor of the loading platform by rising, and the supporting arm supports the long material onto the loading platform by descending. Lower it so that it touches the floor.

[Example] Hereinafter, the present invention will be specifically described with reference to an illustrative example.

FIG. 1 is a side view of an embodiment of the present invention, FIG. 2 is a perspective view of its main parts, and FIG. 3 is a side view of the device in a conveyed state. A truck 1 is constructed by connecting a loading platform 3 to the rear of a driver's seat 2. In reality, gates are provided on both sides and the rear of the floor surface 4, but these are omitted. The long material A is loaded on the floor surface 4 of the loading platform 3, and the long material A is transported. This floor surface 4
A support arm 5 is provided so as to be movable up and down.
The support arm 5 is provided on the driver's seat 2 side of the loading platform 3, and supports one end side of the elongated material A.
Further, a drive box 6 is attached to the lower surface of the loading platform 3, and the support arm 5 is raised and lowered by the operation of drive members (not shown) such as a motor and gears provided in the drive box 6. It's summery. Reference numeral 7 denotes a handle for raising and lowering the support arm 5, and the support arm 5 can be raised and lowered manually. The support arm 5 is provided on the side of the driver's seat 2, and as it rises, the elongated material A is supported such that the end on the driver's seat side is higher than the floor surface 4 of the loading platform 3. Therefore, the long material A and the floor surface 4 of the loading platform 3
Since a gap is formed between the forklift and the forklift, the fork of the forklift can be inserted, and the long material A can be loaded and unloaded. Also, the support arm 5
3, the long material A comes to be supported by the entire floor surface 4 of the loading platform 3 as shown in FIG. Therefore, not only is it possible to have a wide bearing area and stable loading, but also stable transportation is possible by tightening the rope 10 using the gates 9 provided on the sides and rear of the floor 4. becomes. Moreover,
The load on the long material A at the bottom tier is also received by the entire floor surface 4, and damage, denting, and deformation thereof can be prevented.

FIG. 2 shows the state in which the support arm 5 is attached.
As shown in the figure, the support arm 5 is disposed in a direction perpendicular to the longitudinal direction of the loading platform 3, and is provided in a groove 8 formed in the loading platform 3 so as to be freely retractable. Groove 8
The load is set to be somewhat larger than the diameter of the support arm 5, and the support arm 5 is housed in the groove 8 when the support arm 5 is lowered to its lowest position. Therefore, in this state, the support arm 5 does not protrude from the floor surface 4 of the loading platform 3, and the elongated material A is placed entirely on the floor surface 4.

The present invention is not limited to the above-mentioned embodiments and can be modified in various ways. For example, a plurality of support arms 5 may be provided at predetermined intervals on the loading platform 3 to support the elongated material A at a plurality of locations. Further, it may be provided in a direction parallel to the longitudinal direction of the loading platform 3 or in a direction diagonally intersecting it.
Furthermore, the support arm 5 may be provided on the rear side of the loading platform, and may be raised and lowered automatically.

[Effects of the invention] As described above, the present invention is equipped with a support arm that can be raised and lowered from the floor of the loading platform, making it easier to load long materials,
It is effective in that unloading can be carried out smoothly, long materials can be loaded stably, and damage to the materials can be prevented.
