It is known that a mechanism and a hood that is stretched over the stanchion are provided so that the hood can be opened and closed by moving the stanchion along the rail while bending and extending the link mechanism.

[0003]

[Problems to be solved by the device]

 Freight vehicles with hoods are generally of the fixed type in which the hood is fixed, or the open / closed type in which the hood is opened and closed. You may not be able to pass through or enter or leave the factory if there is a vehicle height restriction such as at the entrance of a car.

The present invention allows the height of the hood to be changed so that even when the vehicle height is restricted, it is possible to enter and exit a structure such as a passage or a factory without trouble.

[0005]

[Means for solving the problem and action]

 For this reason, the present invention is, therefore, constructed by connecting the necessary number of panels in the height direction on the tilt and connecting them, and in the fixed type, the leg ends of the columns that are juxtaposed to the fixed type are attached, and in the open and closed type. In this case, a rail is horizontally attached to a panel, and a runner that engages movably with the rail is movably supported by a pillar provided at a leg end, and the pillars are linked by a link so that they can extend and contract. .

According to the present invention, in both the fixed type and the openable type, the hood height is stretched step by step by replenishing the panels or removing the panels. In the fixed type, the support leg end is usually attached to the panel by inserting the support leg end into a tubular mounting portion provided on the panel so that the support leg can be removed. Such a mounting portion may be provided for each panel, or may be provided only for the uppermost panel. In the former case where the mounting part is provided for each panel, the tension at the height of the hood is usually set by removing the support leg end from the uppermost panel where the support leg end is attached. This is done either by adding additional panels, or by removing the required number of panels in order from the top, adjusting the height, and then inserting the ends of the supporting column legs into the mounting portions of the uppermost panel.

In the latter type in which the mounting portion is provided only on the uppermost panel, the height of the hood is adjusted by first removing the uppermost panel having the mounting portion, and then adding or removing the panels. This is done by reconnecting the panels with mountings on them and mounting the strut leg ends. In this case, the support columns are also removed from the panel, but it is possible to remove the top panel with the support columns attached, that is, with the hood attached. When the top panel is removed with the hood attached, the columns can be fixed to the panel by welding or the like.

In the open / close type, rails are attached to each panel or only to the uppermost panel. In this case, as for the method of adjusting the height of the hood, as with the fixed type described above, after removing the runner from the rail and removing the columns, add or remove the panels and then pass the runner through the rail of the top panel. Adopting a method of attaching the support pillars, then removing the top panel with the rails and then the rails, and then removing the panels without adding the panels, and then connecting the panels with rails to the top step and attaching the support pillars. In addition to this, a method of attaching and detaching the panel with the hood attached to the top panel together with the hood can also be adopted, but preferably it extends horizontally toward the cabin at the torii or toward the cargo bed side. Attach the evacuation rail so that it can be moved up and down, move the stanchion to the evacuation rail, fold the hood, and then join the panels, or Performs removed, then the method for moving the post after the level by lifting the retracted rails connected in accordance with the uppermost panel of the rail is employed. In this case, the panels can be removed and re-added simply by folding the hood and retracting it on the retracting rail, and there is no need to remove the hood. When the retract rail is provided so as to extend toward the cargo bed side, the panel side rail connected to this is shortened, excluding the portion corresponding to the retract rail.

Further, when the retracting rail is provided toward the cabin, it is folded so as not to obstruct the entrance and exit of the cabin when unnecessary. In another invention, a frame is mounted on a tilt so that the frame can be moved up and down so that the height can be adjusted, and the leg ends of the columns are fixed to the frame, or rails are mounted horizontally so that the frame can travel. The supporting runners that support the matching runners are movably supported, and the supporting pillars are linked by links so that they can expand and contract.

In the present invention, by raising and lowering the frame, the height of the hood can be changed steplessly to any height, and the adjustment can be performed while the hood is attached. The raising and lowering of the frame in the present invention is preferably performed manually by using a boosting mechanism such as a jack or automatically by using power.
