Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a roof opening/closing device that opens and closes when loading and unloading cargo onto a truck platform.

《Prior art》 The conventional truck loading platform roof opening/closing device is
As shown in the figure, since the roof part and the side flaps are integrated, the side flaps stand diagonally upward when the roof is opened.

<<Problems to be solved by the invention>> When loading and unloading cargo from a truck platform, the top of the platform must be left wide open.
Particularly when working with a crane, opening the roof is an essential condition.

However, when the roof of a conventional truck bed is tilted further backward from an upright position,
As shown in Fig. 4, the side flaps stand diagonally upward, making the roof high and making it impossible to load and unload cargo in low-lying workplaces.

Furthermore, if the side fan portions were to stand up, there was a risk that the truck would fall if it was exposed to strong winds.

Therefore, in view of the above points, the present invention is designed so that even when the roof is fully opened, the side flaps can be kept substantially horizontal using a simple mechanism.

<Means for Solving the Problems> In order to solve the above problems, the present invention is such that a center frame 3 is constructed between the gate-shaped frames 1 installed in front and rear of the truck loading platform 2, and the left and right sides of the center frame 3 are In a truck loading platform in which a roof member 4 is pivotally supported 5 so as to be openable and closable by an opening/closing means, a side fan member 6 is rotatably connected to the roof member 4, and the side fan member 6 and the upper part of the portal frame 1 are connected to each other. A supporting member 8 is provided in between, and when the roof member 4 is opened, the upper part of the roof is opened with the side fan member 6 being in a substantially horizontal state.

<<Operation>> Next, the operation of the present invention will be explained based on the drawings.
When the rod 15 of the cylinder 12 is extended, the roof member 4 rotates upward about the shaft support 5.

On the other hand, since the side fan member 6 which is connected to the roof member 4 by a pivot 7 has a support member 8 pivotally attached 9 to its lower side, it rotates upward together with the roof member 4 while raising the support member 8.

When the roof member 4 stands upright as shown in FIG. 1, the side fan member 6 is supported from below by the support member 8 to maintain its horizontal position.

In addition, when the piston rod 15 is further protruded and the roof member 4 is tilted backwards as shown in FIG. Since the substantially L-shaped support member 8 pivotably mounted 9 stands up and does not tilt any further backward, the upward rotation of the side fan member 6 is restricted by the support member 8, leaving the upper part of the roof open. This will keep it approximately horizontal.

Therefore, in two stages: when the roof member 4 is upright and when it is tilted further backward, the side fan member 6 maintains a substantially horizontal state with the roof upper part open.

<<Embodiment>> The embodiment of the present invention will be described below based on the drawings. In FIGS. A center frame 3 is installed between the frames 1.

Reference numeral 4 denotes a roof member whose base end is pivotally supported 5 on both sides of the center frame 3 so as to be openable and closable, and a side fan member 6 is rotatably supported 7 on the other end.

Reference numeral 8 denotes a substantially L-shaped support rod whose long end is pivoted 9 to the side fan member 6 and whose short end is pivoted 11 to a bracket 10 provided on the portal frame 1.

Reference numeral 12 denotes a hydraulic cylinder whose base end is pivoted 14 to a bracket 13 provided on the portal frame 1 so as to be able to raise and lower, and the tip of the cylinder rod 15 is pivoted 17 to a bracket 16 provided on the roof member 4. has been done.

FIG. 3 shows the device of the present invention mounted on a horizontal stand 18 that is provided on the center frame 1 and moves left and right from the center.

= Effect of the invention = According to the invention, when the roof member 4 stands upright,
Even when the vehicle is tilted further backward, the side fan member 6 maintains a substantially horizontal position, so the roof does not become too high and cargo can be loaded and unloaded even in warehouses, factories, etc. with low ceilings. Additionally, since the upper part of the roof is open, cargo can be loaded and unloaded using a crane outdoors.

In addition, there are fewer surfaces exposed to gusts of wind, making it a highly safe and useful device.
