DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The specific contents of the present invention will be described below with reference to an embodiment of a waste disposal container shown in FIGS. The bottom plate, 8a and 8b indicate link plates, and 18 and 19 indicate fork claw insertion portions. The main body frame 1 is surrounded by four front walls 2.2 and side walls 3.3 of a metal plate to form a square, and has an upper surface open. The front wall 2 has, at the center of the upper end edge, a protruding portion 2a having a height substantially equal to the fork claw insertion portions 18 and 19, respectively.

Further, the bottom plates 6 and 7 are large enough to close the bottom opening of the main body frame 1 and are made of a pair of left and right metal plates of equal size. Each of the legs 4, 4 projecting at or near the bottom of the front wall 2, 2 on both the left and right sides, is bridged between the legs 4, 4, on the symmetric side, in parallel with the side walls 3, 3, respectively. The hinges 5a are formed by hinges 5a formed by the shafts 5 and 5 and are openably and closably attached to each other, and legs 6b 6b and 7b 7b are attached to their free ends.

The link plates 8a and 8b are respectively attached to the front walls 2 on both sides of the main body frame 1 at predetermined intervals in the horizontal direction with the pins 12 and 13 at the intermediate portions. It is rotatably mounted, and has a lower end portion therebelow, and is slidably held along the bottom plates 6, 7 from the mounting portion by the hinge mechanisms 5a, 5a to the open / close free end direction.

In this embodiment, the link plate 8a
The structure of the lower end of 8b, which is slidably held along the bottom plates 6 and 7 in the direction of the legs 6b, 6b and 7b, 7b of the free open / close end from the mounting portion by the hinge mechanism 5a, 5a, has the same bottom. Sliding contact holding bars 10 and 11 are bridged between the lower ends of the link plates 8a and 8a at symmetrical positions for holding the face plates 6 and 7, respectively.
Are always kept in sliding contact with each other.

However, as described above, the link plate 8 is not always required.
It is not necessary to extend the sliding contact holding bars 10 and 11 between the lower ends of the a and 8a. In addition, although not shown, for example, the link plate 8 at a symmetric position for holding the same bottom plate 6 or 7
At the lower ends of a 8a and 8b 8b, there are formed, for example, U-shaped supports for receiving the side edges 6a 6a and 7a 7a of the bottom plate 6 or 7, respectively. The bottom plates 6 and 7 may be held.

Further, the fork claw insertion portions 18 and 19 have a length slightly longer than the distance between the front walls 2 and 2 of the main body frame 1 and have a cylindrical shape large enough to allow the fork claw FP to be inserted therein. None, between the upper end portions of the link plates 8a, 8a and 8b, 8b at the symmetrical positions holding the same bottom plate 6 or 7, respectively, are connected via connecting fittings 14, 16 and pins 15, 17, respectively. The bottom plates 6 and 7 can be opened and closed by inserting the fork claws FP into the fork claw insertion portions 18 and 19 and changing the distance between the fork claws FP.

Further, when the bottom plates 6 and 7 are in a closed state, the pair of left and right link plates 8a and 8b is so arranged that the bottom opening of the container is not inadvertently opened.
A lock mechanism is provided between the lower end portions as necessary.
That is, the lock mechanism is attached to the lower end of one link plate 8b by integrally projecting the locking pin 9b outwardly by welding or the like coaxially with the sliding contact holding bar 11, and attaching the locking pin 9b to the other link plate 8a. At the lower end, a locking pin 9a is protruded toward the outside coaxially with the sliding contact holding bar 10, and a locking groove 2 capable of locking with the locking pin 9b described above.
The hook 20 having the first and operation pieces 22 is rotatably attached. 8c represents a stopper.

Therefore, when the bottom opening of the container is closed, the hook 20 is engaged with the locking pin 9b to lock the pair of link plates 8a and 8b (see FIG. 1), and the bottom opening of the container is opened. In doing so, the hook 20 is detached from the locking pin 9 to release the lock, so that the container bottom opening can be opened (see FIG. 2).

In the above arrangement, the fork claws FP are inserted into the pair of fork claw insertion portions 18 and 19, and the container is lifted by the forklift truck and moved to the destination. In this case, if the lock mechanism described above is applied to the container, it is necessary to release the lock mechanism in advance.

When emptying the waste loaded in the container, the projecting portions 2a are moved in the direction in which the left and right fork claws FP are attracted to each other by the driving force of the forklift.
2a, the fork claw F
The lower portions of the P and FP are mutually opened with the pins 12 and 13 as fulcrums, as shown by arrows in FIG. 3, whereby the pair of bottom plates 6 and 7 are pivotally opened downward with the hinge mechanisms 5a and 5a as fulcrums. And the bottom opening of the main body frame 1 in the container is opened, and the waste as the content falls.

Further, when the falling of the waste is completed, the fork lift side fork pawls FP are moved in the direction away from each other and returned to the original position, so that the bottom opening of the container becomes the bottom plates 6.7. Then, the container is moved back to the required place by the forklift and the operation is completed.

[0021]

As described above, according to the present invention, a rectangular main frame surrounded by front walls and side walls, and a bottom wall on both right and left sides of the front wall of the main frame, or near the bottom wall, is parallel to each side wall. A pair of bottom plates, which are openably and closably attached in a double-opening manner via hinge mechanisms formed on the front and the front wall surfaces on both sides of the main body frame, are provided with a pin at an intermediate portion at a predetermined interval in the horizontal direction. A hinge is attached to the front wall so as to be freely rotatable, and has a lower end portion below the lower end portion. A pair of left and right link plates positioned near the upper edge of the side wall, and a pair of fork claw insertion portions respectively attached between the link plate upper ends at symmetric positions holding the same bottom plate. Since the bottom plate is opened and closed by inserting the fork claws into the pair of fork claw insertion portions and changing the interval between the fork claws, the waste is well separated from the bottom of the container, and therefore, especially metal cutting. It is suitable for handling high-viscosity waste such as cutting chips generated by the above, and can be easily loaded with a forklift when loading the waste from the site to a transport truck or transporting it to a waste storage or disposal site. The bottom can be opened or closed, thus reducing working effort and significantly improving safety.

In the case where the lock mechanism is provided between the lower ends of the pair of left and right link plates when the bottom plate is closed, there is no danger of the bottom being opened carelessly during the operation. Further, in the case where a protrusion having the same height as the fork claw insertion portion is formed at the center of the upper edge of the front wall, not only stability is improved when a plurality of containers are stacked, but also a cylinder. The durability can be improved without crushing the fork claw insertion portion in the shape of a fork or damaging the body frame itself.
