Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container box suitable for storing, transporting, transshipping, etc. various kinds of collected resources and industrial wastes, or raw materials and by-products in various industries. .

[0002]

2. Description of the Related Art As a container box of this kind, the present applicant has previously disclosed in Japanese Patent Application Laid-Open No. Hei 6-127605.
Disclosed is a container box in which contents can be easily stored, transported, and unloaded. This is shown in FIG.
A drop opening is provided at the bottom of the box 100, and a pair of doors 106 are pivotally supported at the opening, and the door 1 is moved by the legs 105 of the box.
06, a pair of guide rails 109 is supported, and a pair of rolling wheels provided with a shaft 111 are engaged with the guide rails in parallel, and a rolling element 112 provided on the shaft is placed below the door. Contact and support.

Further, sprocket shafts 114a and 114b are supported near both ends of the guide rails in parallel with the shaft 111, and the upper side of the sprockets provided at both ends of the sprocket shaft is on one shaft, and the lower side is on the other shaft. , Respectively. With such a configuration,
Hang the container box containing the waste, etc. with a crane or forklift, transport it to a position above the loading platform such as a truck, open the bottom of the box, drop the storage product onto the loading platform, and load it. Is what you use.

[0004] In such a conventional container box, the bottom surface of the box body is opened downward, and the stored items are dropped directly below the bottom. Therefore, when the container box is moved, a hanging string is hung on a hook provided on the box body, and the hanging string is lifted by a crane or a forklift to be moved above the loading platform. For this reason, it is necessary to secure a rotation space below the container box for the bottom surface of the box to rotate and open, and the container box must be held high by that much, Moreover, the fork of the forklift cannot be inserted into the lower side to be supported high.

[0005] Further, if there are obstacles such as fences and other structures, various devices, luggage, and implants between the truck and the cargo bed, the container box passes over the cargo box and rises above the truck bed. In order to reach it, the container box had to be suspended and held at a considerable height and moved, and there was a drawback that a normal-sized forklift was useless. On the other hand, since a crane truck or the like cannot make a small turn, it is much more mobile than a forklift, and there is a possibility that the advantages of the container box cannot be exhibited.

[0006]

SUMMARY OF THE INVENTION It is a first object of the present invention to disclose a container box which does not need to be moved to a position directly above a loading platform or the like by discharging stored items in a lateral direction.

A second object of the present invention is to disclose a container box which can be supported and transported at a higher height than in the prior art by being able to support and move around the bottom with a forklift.

[0008]

A first gist of the present invention is that a half of an inner bottom surface of a box is a fixed slope descending from a lower edge of a first side wall of the box, and the lower edge is close to a lower edge of the slope. The other half of the bottom surface of the box is formed by a movable bottom plate having a center of rotation parallel to the edge and rotatable up and down by a predetermined angle, and all or below a third side wall facing the first side wall. The half portion is formed as a swinging wall which is vertically suspended so as to be swingable with the upper end edge as a center of rotation, and is movable along a second side wall of the box and a fourth side wall opposed to the second side wall. A pair of guide rails are provided near a position sandwiching the bottom plate, a pair of rolling wheels interconnected by a shaft are engaged with the guide rail, and the rolling member provided on the shaft or the shaft is moved to the movable bottom plate. By contacting from below, the movable bottom plate is supported at the upper limit position, The vicinity of the lower end of the swinging wall is detachably engaged with the free end of the movable bottom plate at the upper limit position, and the winding transmission wheels are provided near both ends of the pair of guide rails. While winding, one of a pair of winding transmission wheels opposed to each other across the movable bottom plate is connected by a winding transmission shaft parallel to the shaft and supported so as to be integrally rotatable, A container box, wherein a wrapping transmission strip is connected to the shaft.

The container box according to the first aspect includes:
The movable bottom plate and the rocking wall are engaged with each other to form a box container, which is placed in an appropriate place and used as a storage box, a trash box, or a collection box, and the box body is full of grains, empty cans, earth and sand, and the like. Then, this is moved to the destination, and when the wrapping transmission shaft is driven to rotate, the rolling wheel moves on the guide rail. Then, the shaft connected to the wrapping transmission strip also moves, and the rolling element provided on the shaft rolls toward the lower side of the fixed slope while supporting the movable bottom plate, and deviates from the back surface of the movable bottom plate. Leads to. At that time, since the movable bottom plate loses the support by the rolling elements, it rotates downward by a predetermined angle due to its own weight to form a slope.

It is desirable that the slope formed by the movable bottom plate is set so as to be equal to or more steep than the slope of the fixed slope. At the same time as the movable bottom plate rotates downward, the lower end of the swinging wall is released from the engagement with the free end of the movable bottom plate, and is pushed outward by the weight of the contents. Thus, the contents in the box body fall laterally to the rocking wall side along the slope formed by the fixed slope and the movable bottom plate. As a means for moving the container box, a crane, a forklift, or the like can be used. However, since the contents do not drop directly below the box, there is no inconvenience even if the fork of the forklift is supported from below by the box. As a result, even if the height of the fork is the same, it can be supported at least by a height corresponding to the height of the box, as compared with the case where the conventional container box is suspended and moved.

[0011] The rotation of the drive shaft can be easily turned on the shaft end of the drive shaft by a lever handle detachable at one end. In particular, it is desirable for safety to connect the lever handle to the drive shaft via a ratchet so as to switch the ratchet pawl to prevent the handle from reversing. The engagement means between the lower edge of the swinging wall and the free edge of the movable bottom plate preferably has a configuration in which the swinging wall is disengaged from the engaged state by the lowering operation of the movable bottom plate. The movable bottom plate can prevent the swinging wall from rotating outward, such as a projection projecting in the direction and a hole or ring loosely fitted in the projection, and the movable bottom plate can be easily rotated by rotating downward. It is only necessary that the locked state can be released. Of course, a known manual fastening means may be manually operated and disengaged every time the work is performed.

A second gist of the present invention is to rotate the bottom surface of the box up and down by a predetermined angle with a center of rotation close to and parallel to the lower edge of the first side wall of the box. A swinging plate formed by a movable bottom plate which is inclined at its lower limit position, and which is vertically suspended so that all or a lower half of a third side wall opposed to the first side wall can swing around an upper end edge. A pair of guide rails are provided near the position sandwiching the movable bottom plate along a second side wall of the box and a fourth side wall opposed to the second side wall, and are connected to each other by a shaft. The movable bottom plate is supported at the upper limit position by engaging the shaft or the rolling element provided on the shaft from below with the pair of rolling wheels engaged with each other. Near the lower edge of the swing wall to the free edge of the movable bottom plate A pair of wrapping transmission wheels that are removably locked and provided with wrapping transmission wheels near both ends of the pair of guide rails to wind the wrapping transmission strip, and that face each other across the movable bottom plate. Wherein one of the pairs is connected by a winding transmission shaft parallel to the shaft and supported so as to be able to rotate integrally, and the winding transmission strip is connected to the shaft. .

In the case of the container box according to the first aspect, the movable bottom plate forms a part of the bottom surface of the box, whereas the container box according to the second aspect includes:
The entire bottom surface of the box is constituted by a movable bottom plate. Other configurations are basically the same. However, as a means for supporting the movable bottom plate from below and holding the inside of the box in a closed state by directly contacting the rolling member with the plane of the movable bottom plate, when the rolling member is moved downward by the movable bottom plate The movable bottom plate does not open unless it moves to a position where it does not obstruct the operation. When the movable bottom plate forms the entire bottom surface of the box, the end portions of the pair of guide rails on the first side wall side are provided at positions protruding outward from the first side wall, and the shaft is formed on the first side wall. If it is possible to deviate outside one side wall, the rolling element can deviate from the bottom surface of the movable bottom plate.

On the lower surface of the movable bottom plate, for example, a step forming body made of, for example, a rectangular block or a block provided with a slope near one end of the block is protruded downward, and a rolling element is used to form the step forming body. The movable bottom plate is configured to support the movable bottom plate via the movable bottom plate. The movable bottom plate is configured to be separated from the step forming body near the pivot portion of the movable bottom plate. Further, the distance between the movable bottom plate surface and the rolling element contact surface of the step forming body (step difference) ) Is set so as to be much larger than the diameter of the rolling element, it is not always necessary to provide the guide rail on one side so as to protrude from the third side wall as described above.

[0015] The container box according to the first and second aspects of the present invention is provided with a hook provided on the peripheral portion of the box body, where the content portion is to be dropped even when the container box is suspended and supported by a hanging string such as a wire. It is not necessary to go to the position directly above, and the turning distance of the movable bottom plate downward is shorter than the conventional one, so for example, using a forklift,
The contents can be moved over a high fence to the bed of a truck stopped on the road, and the contents can be discharged at a lower position. Furthermore, if a forklift fork insertion gap is provided below the box bottom plate, the forklift can be transported very safely and suspended even if the box weight center is significantly biased by the contents. Compared to
Can be supported and moved to a high position.

In the case where the entire surface of the box is a movable bottom plate and the rolling elements are directly contacted with and supported by the movable bottom surface, the rolling elements 22 can deviate from the movable bottom plate 5 as shown in FIG. It is necessary to provide the guide rail 18 so as to protrude (18a) outside the first side wall 7. Thereby, the departure space 30 of the rolling element 22 can be provided above the guide rail protrusion 18a.

[0028]

[Effect] Since the container box of the present invention can drop the contents below the side surface, a transportation means such as a forklift lifts the container box just above a position to be dropped due to an obstacle such as a fence. Even when it is not possible to go, it is possible to reload or drop contents while supporting the container box on the obstacle, and in the past it was necessary to avoid obstacles and make a large detour However, the container box of the present application can quickly and efficiently carry out processing such as reloading.

Further, since the contents do not fall directly below the bottom surface, there is an advantage that the fork can be inserted and supported below the box. In this manner, if a forklift is used, the container box can be held higher by at least an amount corresponding to the height of the box body, and obstacles can be avoided without difficulty. Moreover, if a fork insertion portion is provided as in the embodiment, the support and traveling of the box body are remarkably stable, and the operability of work is much better than the case where the fork is hung with a hanging string such as a wire. Excellent safety.
