Both doors 27 are of a double door type, and a vertical front edge 28 of the round bar member 24a of the side frame 24 is connected to a vertical one side edge 29 of the round bar member 27a of the door 27 via a pair of upper and lower hinges 31, respectively. It is connected and rotates horizontally.

Next, the structure of the hinge 31 will be described in detail. The hinge 31 has a substantially cylindrical main body side bearing portion 32 rotatably fitted to the front edge 28 of the side frame 24 on one side, and is rotatably fitted to the side edge 29 of the door 27. A substantially cylindrical door-side bearing portion 33 is provided on the other side. As described above, the hinge 31 has two vertical rotation shafts, and thereby allows the opened door 27 to be rotated to a position overlapping the outside of the side frame 24 in parallel. Also, the hinge 31
Is composed of a pair of hinge members 36 and 37 which are divided by a plane including the both rotary shafts. These hinge members
36 and 37 are fixed to each other at a position between the bearing portions 32 and 33 by a bolt 38 and a nut 39 which are fasteners. When the door 27 is attached to the main body frame 25, both parts of the pair of hinge members 36 and 37, which become the bearing portions 32 and 33, are fitted to the front edge 28 of the side frame 24 and the side edge 29 of the door 27, while the door 27 is attached. The hinge members 36 and 37 may be fixed to each other by the bolt 38 and the nut 39.

Further, a stopper receiving portion 41 is formed on the lower edge of the main body side bearing portion 32 so as to project. On the other hand, a substantially semi-cylindrical stopper piece 42 is fixed by welding to the front edge 28 of the side frame 24 located below the main body side bearing portion 32,
A rotation stopper 43 is formed on the upper edge of the stopper piece 42 so as to project therefrom. The rotation stopper 43 is located on the same circumference about the rotation axis of the stopper receiving portion 41 and the main body side bearing portion 32, and when the door 27 is closed, the stopper receiving portion is formed.
41 hits and regulates the angle of the hinge 31. That is, in this regulated state, the rotary shaft of the door side bearing portion 33 is located on the plane including the rotary shafts of the main body side bearing portions 32 of the left and right hinges 31.

The main body side bearing portion 32 is a front edge of the side frame 24.
Although it is movable up and down with respect to 28, the lower limit position is defined by the stopper piece 42. This stopper piece 42
The position where the main body side bearing portion 32 abuts on the lower end is the lower limit position. On the other hand, the hinge 31 and the door 27 are located on the upper side of the upper door side bearing portion 33 and the lower side of the lower door side bearing portion 33, respectively, and are fixed to the side edge 29 of the door 27 by welding. Positions in the vertical direction are fixed to each other by a semi-cylindrical stopper piece 44.

Further, the upper and lower hinges 31 are fixed to each other by a connecting plate 46. Further, at the lower edges of both doors 27, stopper pins 47 are provided so as to project downward. Meanwhile, the loading platform
The front edge of 21 is provided with a pair of left and right pin insertion portions 48 into which the stop pins 47 are inserted from above when the door 27 is closed. Further, a bar 51 is pivotally attached to the horizontal rail 27c of the one door 27. On the other hand, the horizontal bar 27c of both doors 27 has the bar
Hooks 52 and 53 on which 51 is hooked from above are respectively provided.

Next, the operation of the above configuration will be described. When opening the door 27, turn the bar 51 to hook

After removing from the pin insertion portion 48 of the loading platform 21, the door 27 is rotated horizontally. This rotation is rotation of the main body side bearing portion 32 of the hinge 31 with respect to the front edge 28 of the side frame 24 and rotation of the side edge 29 of the door 27 with respect to the door side bearing portion 33 of the hinge 31. Hinge 31
Is a closed position shown by the solid line in FIG. 2 with respect to the front edge 28 of the side frame 24, that is, from the position where the door 27 is in the front opening of the main body frame 25 and is orthogonal to the side frame 24 to the position shown by the chain line. Angle α
(About 245 ° in this embodiment). At the position shown by the chain line, the side edge 29 of the door 27 is caught on the outer surface of the side frame 24, and the hinge 31 cannot be rotated any more. It will be opened at 25 °. However, even in this state, the door 27 can be further turned toward the side surface frame 24 around the door side bearing portion 33 of the hinge 31. Then, by rotating the door 27 around the door-side bearing portion 33 by an angle β, the door 27 is placed in parallel with the outer surface of the side frame 24.

In this way, articles can be taken in and out of the pallet with both doors 27 opened. Further, the door 27 may be left open even when the article is stored.

When closing the door 27, the door 27 is rotated in the opposite direction. At this time, the side edge 29 of the door 27 is rotated with respect to the door side bearing portion 33 of the hinge 31, and the front edge 28 of the side frame 24 is rotated.
The main body side bearing portion 32 of the hinge 31 is rotated with respect to. In the main body side bearing portion 32, the stopper receiving portion 41 has a front edge of the side frame 24.
It can be rotated to the position where it abuts the rotation stopper 43 fixed to 28. In this position, the hinge 31 is located at the front opening of the main body frame 25 and orthogonal to the side frame 24. Thus, the angle of the hinge 31 when the door 27 is closed is regulated. In addition, the door 27
Is temporarily lifted, and the retaining pin 47 is inserted into the pin insertion portion 48 of the loading platform 21 from above. As a result, the door 27 is also held in the front opening of the main body frame 25 at a position orthogonal to the side frame 24. Further, as shown by the solid line in FIG. 3, when the barbs 51 are turned to be disengaged from the hooks 52 and are hooked on the hooks 53, both doors 27 are securely held in a closed state.

As described above, according to the structure of the above-described embodiment, the hinge 31 has two rotating shafts, so that the open door 27 can be stacked in parallel with the outer surface of the side frame 24. As a result, as shown in FIG. 4, even if the door 27 is opened, the door 27
The 27 does not get in the way, and you can arrange multiple palettes without gaps. Therefore, more palettes can be arranged in a fixed space, and the space for placing the palettes can be saved.

Further, since the angle of the hinge 31 when closed is regulated by the stopper receiving portion 41 and the rotation stopper 43, even though the hinge 31 has two rotating shafts, the stop pin 47 and the bar 51 are provided. Together with this, the angle of the closed door 27 can be surely regulated, and the door 27 can be made orthogonal to the side frame 24, so that the door 27 can be prevented from being closed in a state in which it is delusionally inclined. Furthermore, since the pair of upper and lower hinges 31 are fixed to each other by the connecting plate 46, when the door 27 is opened and closed, the door 27 is twisted up and down even though the hinge 31 has two rotating shafts. This can be prevented and the door 27 can be stably opened and closed.

Further, the hinge 31 is divided into two parts, and a pair of hinge members 36 and 37 constituting the hinge 31 are attached to a bolt 38.
Since they are fixed to each other with the nut 39 and the nut 39, the hinge 31 can be retrofitted to the main body frame 25 and the door 27.
The combination of 25, door 27, and hinge 31 can be freely set.
Therefore, versatility in manufacturing is enhanced and cost can be reduced.

The present invention is not limited to the above embodiment, and various modifications can be made. For example,
In the above-mentioned embodiment, the pair of hinge members 36 and 37 are fixed by one set of bolts 38 and nuts 39, but they may be fixed by two sets of bolts and nuts, and fasteners other than bolts and nuts are used. You may fix it. Further, as described above, it is more advantageous to manufacture the hinge by fixing the pair of hinge members with bolts or nuts, but
The hinge may be assembled in advance to the body frame or the door by using welding or the like. Furthermore, in the above-described embodiment, the stopper receiving portion 41 and the rotation stopper 43 regulate the angle of the hinge 31 so as to be orthogonal to the side frame 24 when the door 27 is closed, but the angle is not limited to this, and, for example, The hinge may be slightly forward.
