BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a canopy opening and closing device for a vehicle packing box in which an opening opening above a packing box mounted on a vehicle frame is opened and closed by a canopy.

[0002]

2. Description of the Related Art Generally, in such a canopy opening / closing device for a vehicle packing box, a hinge is provided on an upper surface of a side wall of the packing box.
The left and right canopies are respectively opened and closed with the rotation of the arm supported by the hinge. In this case, since the size of the packing box itself in the vehicle width direction is set to the full range of the standard, the hinge needs to be provided on the upper surface of the side wall of the packing box on the inner side of the vehicle body than the outer surface of the side wall.

[0003]

However, when opening the canopy as described above, if the arm is rotated outward from the packing box with the hinge as a fulcrum, the rotation locus of the canopy is determined by the side wall of the packing box. It is a large one that protrudes outward by the length of the arm.

Further, since the fulcrum (hinge) of the arm is located on the inner side of the vehicle body on the upper surface of the side wall of the packing box, when the canopy is opened, the arm is positioned on the outer surface of the side wall of the upper surface of the packing box. The contact is restricted from further rotation, and the canopy at the open position protrudes outside the side wall of the packing box, which is an obstacle.

The present invention has been made in view of such a point, and an object of the present invention is to make it possible to open and close the canopy effectively by two foldable arms so that the canopy pivots. To minimize the amount of overhang to the outside, and to make the canopy in the open position fall down along the outer wall of the packing box so that it does not get in the way without protruding outside the side wall of the packing box. It is.

[0006]

In order to achieve the above object, the present invention divides the canopy into an outer canopy portion located on the side wall side and an inner canopy portion located on the center side of the packing box. By opening and closing the outer part and the inner part of the canopy with separate arms, the opening and closing operation of the canopy is performed.

[0007] Specifically, a solution taken by the present invention is that an opening opening the upper surface of a packing box mounted on a vehicle frame is divided into two parts on the left and right sides. It is assumed that a canopy opening / closing device for a vehicle luggage box is opened and closed by being opened and closed by opening and closing an opening position. A hinge is provided on the inner side of the upper side wall of the packing box on the inner side of the side wall with respect to the outer side surface of the packing box, and the hinge opens and closes an outer portion of a canopy covering a portion of the opening located on the side wall side of the packing box. A base end of the first arm for operation is supported, and a tip end of the first arm opens and closes a canopy inner portion that covers a portion of the opening located on the center side of the packing box. The base end of the second arm for rotation is rotatably supported. The length of the first arm is set such that when the canopy is opened, the tip of the first arm abuts on the upper surface of the side wall of the packing box, and the end thereof is located immediately outside the outer surface of the side wall of the packing box. . A state in which the first arm is in contact with the upper surface of the side wall of the packing box when the canopy is opened, on a rotation support portion that rotatably supports the base end of the second arm with respect to the distal end of the first arm. A first stopper that regulates the rotation range of the second arm so that the second arm falls down on the vertical line along the outer surface of the side wall of the packing box, and the first arm contacts the upper surface of the side wall of the packing box when the canopy is closed. It is assumed that a second stopper that regulates a rotation range of the second arm is provided so that the second arm is positioned on an extension of the first arm in a substantially horizontal state in contact with the second arm.

[0008]

With the above arrangement, in the present invention, when the canopy is opened, the first arm supported by the hinge on the inner side of the vehicle body with respect to the outer surface of the side wall on the upper surface of the side surface of the packing box rotates. The outer portion of the canopy located on the side wall side of the first arm is moved in the canopy opening direction, and the second arm rotatably supported by the tip of the first arm with the rotation of the first arm.
The second arm is positioned so as to be on an extension of the first arm.
With the rotation range restricted by the stopper, the canopy is moved in the canopy opening direction, and the inner portion of the canopy located at the center of the packing box is moved in the canopy opening direction together with the second arm. Then, when the first arm further pivots outwardly of the packing box beyond a vertical line passing through the center of rotation of the hinge, the second arm pivots to a pivoting range regulated by the first stopper. Thereafter, the first arm abuts against the upper surface of the side wall of the packing box to restrict the further rotation of the first arm. In this state, the opening of the outer portion of the canopy is completed, and the second arm is rotated by the first stopper. The canopy falls down in a state where the movement is restricted, and the opening of the inner part of the canopy is completed. The opening operation is completed with the inner part of the canopy bent.

In this case, the rotation range regulated by the first stopper of the second arm is set such that the second arm falls down on a vertical line while the first arm is in contact with the upper surface of the side wall of the packing box. As a result, when the canopy is opened, the inner portion of the canopy is opened along the outer surface of the side wall of the packing box. Further, the length of the first arm is set such that the tip of the first arm when the first arm comes into contact with the upper surface of the side wall of the packing box is located just outside the outer surface of the side wall of the packing box. The arm and canopy inner portion will lie down as close as possible to the outer side wall surface of the packing box.

On the other hand, when the canopy is closed, the outer portion of the canopy is moved in the canopy closing direction by rotating the first arm, and the second arm is rotated by the first stopper with the rotation of the first arm. In the restricted state, the canopy is moved in the canopy closing direction, and the inner portion of the canopy is moved together with the second arm in the canopy closing direction. Then, when the first arm rotates further inward of the packing box over a vertical line passing through the rotation center of the hinge, the second arm rotates to a rotation range regulated by the second stopper. Thereafter, the first arm is rotated until the second arm is positioned substantially horizontally, for example, in a state where the second arm is positioned on an extension of the first arm, and in this state, the closing of the outer canopy portion and the inner canopy portion are both completed, The canopy completes the closing operation with the first arm and the second arm positioned on an extension of the first arm, with the canopy outer portion and the canopy inner portion both horizontal.

[0011]

As described above, according to the canopy opening / closing device for a vehicle luggage box of the present invention, the second arm is positioned on the extension of the first arm when the canopy is closed, and the first arm is placed on the luggage box when the canopy is opened. The second arm is made to fall down on the vertical line along the outer surface of the side wall of the packing box while being in contact with the upper surface of the side wall of the packing box. The cantilever can be made compact so that the rotation trajectory of the canopy is small with a small amount of outward protrusion, and the second arm can be attached to the outer surface of the side wall of the packing box together with the inside of the canopy so that the canopy does not interfere. Can fall down as far as possible.
