Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container suitable for transporting waste and the like. 2. Description of the Related Art A container for transporting household garbage or industrial waste to a waste transporter, a waste disposal site, or the like has a structure in which a bottom cover of a container body is freely openable and closable. ing. This type of conventional container is a type of waste that is stored in a container when the container is suspended by a crane or the like and the bottom cover is unlocked or the bottom cover is opened by manually operating a handle or the like. Is transferred to a truck or a predetermined place. [0003] However, in the above-mentioned conventional container, when the bottom cover is opened, the waste inside the container is vigorously discharged, and particularly in the case of dangerous garbage, the work is dangerous. There is a problem that accompanies. [0004] The present invention has been made in view of such problems, and an object of the present invention is to provide a container which can transfer contents very safely. According to the present invention, there is provided a container body, a double-opening bottom cover provided on the container body so as to be openable and closable, and a vertically sliding pair of opposing side surfaces of the container body. A pair of slide members, which are freely provided and have lower ends forming leg portions, connect the pair of slide members and the bottom cover, and open the bottom cover as the slide members move downward. And a lock mechanism that is provided on a pair of side surfaces of the container body and engages with the slide member to fix the slide member to the container body at a position where the bottom cover is closed. It is characterized by the following. According to a preferred aspect of the present invention, there is provided a container capable of remotely opening the lock mechanism with a wire or the like. According to the present invention, the container body is transferred to a predetermined position by a crane or the like while the slide member is fixed by the lock mechanism, and the container body is temporarily lowered at the place where the contents are discharged. Then, when the lock mechanism is released and the container body is again caught by a crane or the like, only the container body is caught upward with the lower end portion forming the leg of the slide member landing. Along with this, the connecting member connecting the slide member and the bottom lid gradually opens the bottom lid, so that the opening operation of the bottom lid is interlocked with the fishing operation of the container body.
Therefore, when the bottom cover is opened, the worker does not need to stay near the container, and danger is avoided. If the lock mechanism is configured to be released from a remote place by a wire or the like, the unlocking operation can be performed at a remote place, thereby further reducing the risk of work. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a container according to an embodiment of the present invention in a grounded state, and FIG. 2 is a perspective view of the container with a bottom cover opened. At the bottom of the box-shaped container body 1 having an open upper part, double-opening bottom lids 2 and 3 are attached by a hinge 4 or the like so as to be opened and closed. Legs 5 are attached to the bottom lids 2 and 3, respectively. A slide member 6 is provided on a pair of side surfaces of the container body 1. The slide member 6 is shown in FIG.
As shown in the section taken along the line AA of FIG. 1, the roller 8 slides up and down by a roller 8 that moves along a guide rail 7 formed on the inner wall of the container body 1. The lower end of the guide rail 7 constitutes a leg. The upper end of the slide member 7 and the engaging portions 9 projecting outward at the ends of both side edges of the bottom lids 2 and 3 are connected by bar-shaped connecting members 10 respectively. A flange 11 protruding outward is formed at the upper end of the slide member 6. On the other hand, at the center of the upper edge of the side surface of the container body 1 where the slide member 6 is provided, a lock mechanism 12 which engages with the flange 11 of the slide member 6 is formed. Details of the lock mechanism 12 are shown in FIGS. That is, a pair of levers 14 are rotatably supported by a pair of support portions 13 extending from the container body 1. A lock plate 15 is rotatably supported by the pair of levers 14. A handle 16 is fixed to the lock plate 15. Further, a pair of support projections 17 extending from the container body 1 are provided protruding slightly below the lock plate 15. On both sides of the lock mechanism 12 of the container body 1, there are provided ridges 18 extending horizontally. A pair of handles 19 for connecting the both side surfaces of the container body 1 are mounted on the projections 18. At the upper central position of each handle 19, a crane engaging portion 20 for catching the container by a crane or the like is provided. According to the container of this embodiment constructed as described above, when the container is grounded as shown in FIG. 1, the lower end of the slide member 6 is grounded. On the other hand, it is pushed up to the top position. As a result, as shown in FIG. 4, a gap is formed between the lower surface of the flange portion 11 of the slide member 6 and the upper surface of the support protrusion 17. When the handle 16 is pushed down to a substantially horizontal position, the lever 14 swings. By the operation and the rotation operation of the lock plate 15, the edge of the lock plate 15 enters between the flange portion 11 and the support protrusion 17. As a result, the slide member 6 enters a locked state in which the downward movement of the slide member 6 is prevented. In this locked state, the container is
Even if it is caught, etc., since the slide member 6 does not move downward, the bottom lids 2 and 3 maintain a closed state. When the container is moved to a predetermined position by the crane 21 and is once lowered to a lower position, and the handle 16 is raised by an operation opposite to the above-described locking operation, the locking plate 15 is moved to the flange 11 as shown in FIG. Since the slide member 6 comes off from the space between the slide member 6 and the support protrusion 17, the slide member 6 can freely move downward. When the container is caught by the crane 21 in this state, as shown in FIG. 2, only the slide member 6 remains without being caught, so that the lower end of the connecting member 10 is opened outward, and the bottom cover is interlocked with this. A few will be released. As shown in FIGS. 4 and 5, it is desirable to provide a stopper 22 on the upper end surface of the slide member 6 which rotates outward in this plane. By rotating the stopper 22 outward by 90 ° as shown by the arrow in FIG. 4, the possibility of the lock mechanism 12 being unlocked during transfer in the locked state can be reduced. If the surface on which the container is arranged has irregularities, it is expected that the lower end of the slide member 6 will be in a floating state. In this case, a sufficient gap cannot be secured between the flange 11 and the support protrusion 17, and the lock mechanism 12 is hard to lock. For this reason, for example, as shown in FIG.
Is provided, and is made to protrude slightly downward, so that the slide member 6 is always pushed upward, so that it can be easily locked in any situation. Further, as shown in FIG.
If the tip of the wire 24 is fixed to the handle 16 and the wire 24 is pulled out from the container via the pulley 25 or the like, the lock can be remotely released by pulling the wire 24. For this reason, work safety is further improved. In the above embodiment, the contents of the container are not particularly mentioned, but the contents are waste,
Any material such as a raw material may be used. As described above, according to the present invention,
With the slide member fixed by the lock mechanism, the container body is transferred to a predetermined position by a crane or the like, and the lock mechanism is released while the container body is temporarily lowered at the place where the contents are discharged, and then the crane or the like is again released. When you catch the container body with
With the lower end portion forming the leg of the slide member landing, only the container body is lifted upward, and the connecting member connecting the slide member and the bottom cover gradually opens the bottom cover. As described above, since the opening operation of the bottom cover is interlocked with the fishing operation of the container body, the worker does not need to stay near the container when the bottom cover is opened, so that danger is avoided.
