DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport container capable of storing and transporting dust and the like.

[0002]

2. Description of the Related Art In general, a refuse collection vehicle is configured such that a refuse input box provided with an appropriate refuse loading device is tiltably connected to a rear opening of a refuse storage box. In such a garbage collection vehicle, there is known a garbage collection vehicle provided with a reversing device capable of lifting and reversing a transport container facing below an input port of a trash input box. By lifting and inverting the dust, the dust and the like stored in the transport container are discharged to the dust input box through the input port, and loaded into the dust storage box via the dust loading device (for example, Japanese Utility Model Publication No. Sho 62-43923). Reference).

A transfer container that can be inverted by the reversing device is composed of a plastic container body having an open upper surface, a pair of front and rear casters rotatably supported by the container body, and one peripheral wall of the container body. It consists of a pivot mounted with its end protruding beyond both ends of its peripheral wall. The above-described reversing device is configured so as to pinch and lift both protruding ends of the pivot shaft attached to the transport container.

[0004]

However, since such a transport container must support the weight of the container body and the load such as dust contained in the container via the pivot shaft, it is necessary to support the pivot shaft. A thick supporting portion is formed on one peripheral wall of the container body. For this reason, the container body cannot adopt a low-cost molding method in which the thickness is constant, for example, a rotational molding method or a blow molding method, and an injection molding method in which the thickness of the peripheral wall can be changed. However, there is a drawback that the cost increases due to the necessity of molding. In addition, since the supporting portion of the pivot shaft is formed of the same material as the container body, that is, plastic, there is a problem that the supporting portion is damaged when repeatedly lifted by the reversing device.

The present invention has been made in view of the above-mentioned problems, and is intended to reduce the cost of a plastic container molded by a rotational molding method or the like to a reversing device requiring a pivot shaft. An object of the present invention is to provide a transport container that can be used.

[0006]

According to a first aspect of the present invention, there is provided a transport container according to the present invention, comprising at least a plastic container body having an open upper surface, and a caster rotatably supported by the container body. A metal reinforcing plate having an L-shaped cross section is fixed to the front surface or the back surface of a pair of adjacent corners of the container body, and a metal saddle is provided on the surface side of one peripheral wall forming the pair of corners. And a pivot shaft is attached via this saddle.

According to a second aspect of the present invention, there is provided a transport container according to the present invention, comprising at least a plastic container main body having an open upper surface, and a caster rotatably supported by the container main body. A metal reinforcing plate having an L-shaped cross section is fixed to the front surface or the back surface of the pair of corner portions, and a metal saddle is welded to the reinforcing plate on the front surface side of one peripheral wall forming the pair of corner portions. It is fixed and integrated, and a pivot is attached via this saddle.

Further, in the transport container according to the third aspect of the present invention, the metal reinforcing plate having an L-shaped cross section of the transport container according to the second aspect is vertically short.

[0009]

A metal reinforcing plate is fixed to a pair of adjacent corners of a plastic container main body constituting a transport container, and a pivot shaft is connected via at least a pair of metal saddles connected and fixed to the reinforcing plate. Installed.

As a result, a plastic container can be easily
In addition, the pivot shaft can be firmly attached, and dust and the like can be discharged using a reversing device that requires the pivot shaft.

The reinforcing plate 14 is long in the vertical direction, but if the upper and bottom portions of the container body are reinforced, a metal reinforcing material having a short L-shaped cross section in the vertical direction of a portion to which the saddle 16 is fixed is provided. It may be.

In the above example, the saddle 16 is fixed to the reinforcing plate 14 with rivets or bolts and nuts. However, the saddle 16 may be fixed by welding as shown in FIG. In this case, the reinforcing plate 14 only needs to be large enough to fix the saddle 16 by welding, and is preferably a metal reinforcing member having an L-shaped cross section whose vertical direction is short. The reinforcing plate 14 and the saddle 16 fixed by welding are integrally connected to each other via rivets or bolts and nuts with the support plate 15 sandwiching the corners of the peripheral walls 111 and 112 of the container body 11.

In these embodiments, the metal saddle 16 is also provided at the center of the surface of one peripheral wall 111 of the container body 11.
A is provided, but when the capacity of the container body 111 is small,
It is not necessary.

In these embodiments, the pivot shaft 13 is attached via the saddle 16 to the container body 11 having the upper surface opened, and the transport container B corresponding to the above-described reversing device requiring the pivot shaft is provided. However, the pivot shaft 13 may be attached to the transport container B1 applicable to the reversing device 3 shown in FIG. 6 so as to correspond to a reversing device requiring the pivot shaft 13.
