Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a vehicle carrying deck which is attached to a truck or a trailer and is used for carrying a vehicle, and particularly to the rear of a lower deck. The present invention relates to a vehicle transport deck provided with a rocking deck for rocking up and down, which rocks vertically between vehicle frames of a loading platform.

(Prior Art) Generally, a vehicle transport deck is designed to load a large number of vehicles, and is attached to a rear portion of a truck or a trailer so as to transport the vehicles. When loading the vehicle, a road board called a boarding board is placed between the deck and the ground, and when the vehicle is loaded, the road board is removed and stored in a predetermined place.

To install the road plate, it is necessary to match the width of the wheels of the vehicle on which the road plate is to be loaded, and to remove the road plate, the road plate must be carried to a predetermined location. The work efficiency of loading is poor and there is a problem in ensuring safety.

Therefore, for example, Japanese Unexamined Patent Publication (Kokai) No. 60-244638 discloses a vehicle transporting deck in which the lower deck is formed so as to be swingable up and down so as to swing up and down to solve the above problems. In this type of vehicle transport deck, the license plate is usually attached to a license plate attachment plate attached to the rear end of the swing deck.

(Problems to be solved by the invention) However, since the rear end of the rocking deck contacts the ground when the vehicle is put in, if the mounting position of the license plate mounting plate is low, it will damage the ground. In addition, if the mounting position is high, the vehicle may come into contact with the lower surface of the vehicle and get damaged when the vehicle enters the vehicle.

As a method of solving this, it is conceivable that the license plate mounting plate has a structure that can be rotated around a horizontal axis so that the license plate mounting plate can be tilted down when the vehicle is put in. The license plate mounting plate must be operated separately from the operation, and the work is not easy, and if the operation is forgotten, the license plate mounting plate may be damaged.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle transport deck that is easy to operate and does not have a risk of damage to the license plate mounting plate due to forgetting the operation.

[Constitution of device]

(Means for Solving the Problem) As a means for achieving the above-mentioned object, the present invention provides a vehicle-moving rocker mounted between the vehicle frames of the rear deck of the lower deck so as to be vertically swingable around the front end as a fulcrum. A moving deck, a number plate mounting plate mounted on the rear end of the swing deck, swinging about a horizontal axis from a substantially vertical state to a substantially horizontal state, and located on the upper side of the swing deck; At the both ends of the deck in the width direction, each is provided so as to be rotatable around a vertical axis by a required angle, and is rotated to the lock side to position the lock arm on the vehicle frame. And a pair of stoppers that allow the rocking arm to rock downward by rotating the rocking arm downward and rotating the lock arm to the lock release side to retract the lock arm from the vehicle frame. ,this Both the stoppers are interlocked via the license plate mounting plate, and when one of the stoppers is rotated to the lock side, the license plate mounting plate is brought into a substantially vertical state, and
And an interlocking mechanism for setting the license plate mounting plate in a substantially horizontal state when the stopper is rotated to the unlocking side.

(Operation) In the vehicle transport deck according to the present invention, the pair of stoppers for locking and unlocking the rocking deck and the license plate mounting plate mounted on the rear end of the rocking deck form the interlocking mechanism. Are connected through. For this reason, if one of the stoppers is rotated to the lock side, the license plate mounting plate is brought into a substantially vertical state, the other stopper is rotated to the lock side, and the one stopper is locked. When it is rotated to the release side, the license plate mounting plate swings to a substantially horizontal state and is positioned on the upper surface side of the swing deck, and the other stopper rotates to the lock release side. Therefore, it is possible to prevent the license plate mounting plate from being damaged only by performing the original operation of the stopper without being aware of the tilting operation of the license plate mounting plate, and the operation will not be forgotten. Further, since both stoppers are interlocked with each other, it is only necessary to operate one of the stoppers, and the operation itself of the stopper becomes easy.
