FIG. 7 shows a perspective view of the upper portion of the box type pallet. As shown in the figure, fork insertion holes (12) through which forks of a forklift truck can be inserted and removed are formed at both sides of the front plate (10a) and the rear plate (10c) of the box body (10). You. Further, a positioning member (13) at the time of stacking, which also serves as a hanger, is mounted slightly inside the four corners at the upper end of the box body (10) so as to project substantially upward. This positioning member (13) can be used not only as a hanging fitting when hoisting by a crane or the like, but also when positioning a plurality of box-type pallets as shown in the phantom line in FIG. Material (13)
Of the upper pallet, the front leg (31) and the side legs (3
2) and the inside of the four corners formed by the rear legs (33) respectively, all four horizontal positionings are achieved.

In FIG. 1, (80) is a string for remotely operating the operating lever (54), (81) is for guiding the operating direction of the operating lever (54), and for restricting the operating amount. Is a guide member.

When this box type pallet is used for temporary storage of waste in a factory, for example, a bottom cover (2
0) is closed, the stopper (61) is set to the open restriction state as shown by the solid line in FIG. 6, and the stopper (61) is placed in the factory in that state. Then, the waste generated in the factory is stored in the pallet through the upper opening of the box-type pallet. At the time of storage, in this box-type pallet, since the positioning members (13) are attached to the four corners at the upper end of the box body (10), the work of storing waste can be performed smoothly. That is, if the positioning member is attached near the center of the front plate and the rear plate, the waste comes into contact with the positioning member to hinder the storage of the waste, but in this pallet, the positioning member (13) is used. Is located in the corner,
The waste hardly touches the positioning member (13) during storage, and the waste can be stored smoothly.

Next, when the waste stored in the box-type pallet is loaded on the bed of the truck for discharging to the outside of the factory, the stopper (61) is rotated to open it as shown by an imaginary line in FIG. After setting to the allowable state, the fork of the forklift truck is inserted into the fork insertion hole (12) of the box type pallet and the box type pallet is lifted above the truck bed. The operating lever (54) is connected to the cord (80).
Open the bottom lid (20) by pulling backwards through. In this case, the lower end of the connection lever (52) is rotatably attached to the upper end of the hook (51), and the rotation of the connection lever (52) causes the hook (51) to rotate in the disengagement direction. Due to the lever action defined by the connecting lever (52) and the like, a large rotational force can be generated on the hook (51) even with a small operating force. Therefore, the load of the bottom lid (20) and the waste is applied to the hook (51), and the hook (51) and the hook receiving metal fitting (2).
2) Even if a large frictional force is generated between
The engagement between the two can be released smoothly. Therefore, even when the Bucks type pallet is suspended, the bottom lid (20) can be opened, and the operability when opening the bottom lid can be favorably ensured. However, when the bottom lid (20) is opened, it is not always necessary to suspend the pallet, and the bottom lid (20) is unlocked while the pallet is placed on the truck bed to lift the pallet. However, the bottom lid (20) may be opened.

Thus, when the bottom lid (20) is opened,
The waste stored in the box-type pallet is dropped from the lower end opening of the box body (10), and the bottom lid (2
It slides down the upper surface of 0) and is loaded on the truck bed. At this time, since the guide plates (21) and (21) are attached to both side edges of the upper surface of the bottom lid (20),
The guide plates (21) (21) prevent the waste from being scattered, so that the waste can be accurately guided to a desired position on the loading platform.

Further, while the hitting metal fittings (40) are attached to the rear portions on both sides of the lower surface of the bottom lid (20), the hitting metal fittings (40)
Since the stopper plate (41) that receives the welding is welded to the lower end of the box body (10) and the rear leg (33) at two locations, the hitting metal fitting (40) comes into contact with the bottom of the stopper plate (41). When the load of the lid (20) and the waste is applied, the load is distributed to the lower end of the box body (10) and the rear leg part (33). For this reason, local concentration of the load is avoided, premature deterioration of the bottom lid supporting portion such as the stopper plate (41) is prevented, and the durability performance is improved. Moreover, since the buffer member (42) such as hard urethane rubber is attached to the contact area of the stopper plate (41) with the hitting metal fitting (40), the buffer member (42) is attached.
As a result, the impact force on the stopper plate (41) at the time of contact of the hitting metal piece (40) is alleviated, and from this point as well, the stopper plate (41) is prevented from premature deterioration and the durability is further improved.

After the waste is loaded on the loading platform of the truck, the box-type pallet is once lowered on the loading platform and the bottom lid (20) is closed as described above, and then returned to a predetermined position. .

In the treatment of such waste,
When a crane is used instead of the forklift truck, the hook of the crane may be hooked on the positioning member (13) at the upper end of the box-type pallet to raise and lower the pallet and move it horizontally.

On the other hand, when the position of the box-type pallet placed in the factory is changed by using, for example, a forklift truck, the hook (51) of the box-type pallet, the connecting lever (52), and the operation of the box-type pallet during operation Even if the bottom cover opening mechanism such as the lever (54) and the connecting rod (55) accidentally comes into contact with the operator's body or peripheral equipment, the stopper (61) is in the bottom cover opening regulation state shown by the solid line in FIG. Once you have set, it is prevented from actuation of the bottom lid opening mechanism, bottom lid (20) is prevented from inadvertent opening of.
In this case, a member interlocking with the hook (52), for example, an operation

is there. Therefore, in the present invention, the hook (52)
A stopper that can regulate the operation of the members that interlock with
It is only necessary that the stopper is attached,
It is not limited to a specific one.

In the above embodiment, the box type pallet is used for waste treatment, but the present invention is not limited to this, and it can be used for conveying small items such as parts.

[0034]

As described above, according to the box type pallet of the present invention, for example, one end portion of the stopper is rotatably attached to the rear position of the operation lever of the box body via the support shaft, and the stopper is provided. The operation of the engagement body can be set by freely setting the switch between the lever operation regulation state that intervenes between the operation lever and the support shaft and the lever operation permission state where the stopper is pulled out between the operation lever and the support shaft.
Since it is configured to be restricted, it is possible to set the stopper to the lever operation restricted state, such as when the operation of the engaging body is restricted.
By setting, even if the operating member such as an operation lever, in contact inadvertently the body of the operator and peripherals, which
Is restricted et actuation is, while the bottom lid is prevented from inadvertent opening of sets stopper lever operation permission state
For example, if the operation lever is operated, the bottom cover can be opened without any trouble by setting the engagement member in a state in which the operation of the engagement member is allowed.

Further, a deformed fan-shaped stopper is used, and the short side portion of the stopper is arranged on the side of the intervention direction between the operation lever and the support shaft, and the long side portion is arranged on the side opposite to the intervention direction. In this case, even if vibration or the like occurs in the lever operation restriction state, the vibration causes the stopper to shift in the intervention direction due to its own weight. At this time, the operation lever is pushed forward along the arc portion of the stopper to more reliably regulate the opening of the bottom lid. In this way, the lever operation restriction state by the stopper is not released even with respect to vibration and the like, and sufficient safety is provided.
