Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle having an expandable / contractible packing box.

[0002]

2. Description of the Related Art Conventionally, as one form of a vehicle equipped with an expandable / contractible luggage box, a movable side luggage box forming body is provided in a fixed side luggage box forming body fixed to a vehicle body frame, and Is equipped with an advancing / retreating actuation mechanism,
There is one in which the advancing / retracting position can be freely changed between a housing position housed in the fixed-side packing box forming body and a projecting position protruding outward from the fixed-side packing box forming body. The fixed-side floor portion of the fixed-side cargo box forming body includes a fixed-side floor portion forming body, a support frame body that supports the fixed-side floor portion forming body so that the fixed-side floor portion forming body can be raised and lowered, and the support frame body and the fixed-side floor. And a tilting actuation mechanism interposed between the part forming body.

In this way, by operating the advancing / retreating operation mechanism, the movable-side load box forming body is advanced to the projecting position, and in this state, the falling operation mechanism is operated to move the fixed-side floor forming body. The fixed side floor forming body can be made to lie down so as to be flush with the movable side floor forming body of the movable side cargo box forming body.

Further, by operating the fall-down actuating mechanism to erect the fixed-side floor forming member, in the same state, the advancing / retreating actuating mechanism is actuated so that the movable-side floor forming member interferes with the accommodation position. I am able to retreat without.

[0005]

However, in the above-mentioned vehicle, the operation for moving the movable-side packing box forming body forward and backward by the forward-backward movement mechanism and the operation for moving the fixed-side floor portion forming body forward by the fall-down operating mechanism are performed. Since it is necessary to carry out the steps one by one, there is a problem that it takes time to expand and contract the packing box.

In addition, in the operation of the advancing / retreating operation mechanism and the fallen operation mechanism, if the operator makes a mistake in the operation procedure, the movable-side packing box forming body and the fixed-side floor forming body collide with each other, and either or both of them are damaged. There is a problem that it is done.

Therefore, if the detection means and the control means are provided so that the forward / backward movement mechanism and the fall-down movement mechanism are properly operated, respectively, the manufacturing cost of the vehicle increases accordingly.

[0008]

Therefore, in the present invention, a movable-side load box forming body is provided in a fixed-side load box forming body fixed to a vehicle body frame, and the movable-side load box forming body is the fixed-side load box forming body. In a vehicle equipped with a retractable storage box housed in the forming body, and an expansion / contraction type storage box that can be moved back and forth between the fixed side storage box forming body and the projecting position protruding outward from the fixed side storage box forming body,
The fixed-side floor portion of the fixed-side cargo box forming body includes a fixed-side floor portion forming body and a support frame that supports the fixed-side floor portion forming body so that the fixed-side floor portion forming body can be tilted up and down. The body is arranged to fall down in conjunction with the advancing operation of the movable side cargo box forming body to the projecting position, and to stand up in conjunction with the retracting movement of the movable side packing box forming body to the accommodation position. The present invention provides a vehicle equipped with an expandable / contractible luggage box.

The present invention is also characterized by the following configurations.

In the fixed-side floor part forming body, one side edge portion on the side opposite to the side on which the movable-side load box forming body projects is pivotally supported on the support frame body, and the other side edge is centered on the same side edge portion. The part is flipped upward from the support frame to be in an upright position, and the rest position is laid down on the support frame to be in a standing position. An advancing / retreating operation mechanism is provided between the support frame and the movable side cargo box forming body, and the advancing / retreating operating mechanism enables the advancing / retreating slide operation of the movable side cargo box forming body between the projecting position and the accommodation position. At the same time, an interlocking mechanism is provided between the movable-side load box forming body and the fixed-side floor forming body, and the interlocking mechanism causes the movable-side loading box forming body to move forward and the fixed-side floor forming body to fall. And the backward movement of the movable-side packing box forming body and the standing movement of the fixed-side floor forming body.

The fixed-side floor part forming body in the use position in a recumbent position on the support frame and the movable-side floor part of the movable-side packing box forming body are flush with each other, and the inside of the movable-side floor part is the same. A push-up action portion that acts to push up the tip edge portion of the fixed-side floor forming body is provided at the edge portion.
