DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the refuse collection box according to the present invention will be described with reference to the drawings. The basic structure of the refuse collection box is substantially the same as that shown in FIGS. 7 and 8, and includes a box main body 1, left and right lid support legs 2, and a lid 3. As shown in FIGS. 1 and 2, the box body 1 has a pair of left and right side frames 4 and 4 formed by bending a metal pipe material or the like into a U-shape, and the same bottom side between the left and right side frames 4 and 4. A front, rear, left and right lower frame rod 5 made of a shaped steel material or the like formed in a planar shape, and a front, rear, left, right upper frame rod 6 laid in parallel above the lower frame rod 5 between the left and right side frames 4. And a front wall plate 8, a rear wall plate 9, left and right side wall plates 10 and 11, a top wall plate 1 having an arc-shaped cross section.
The left and right side wall plates 10 and 11 are stretched and fixed by screws, welding, or the like.
A garbage bag inlet / outlet 14 is formed between the front of the upper wall plate 12 and the upper end of the front wall plate 8 therebetween.

The front wall plate 8 includes front left and right wall plates 8a and 8a made of blind plates, and a front center wall plate 8b made of a mesh plate material.
The front left and right wall plates 8a and 8a are fixed to the front upper and lower frame rods 6 and 5, and the front center wall plate 8b is detachably attached. The front central wall plate 8b is made of a mesh plate material so that the collection truck can easily check the presence or absence of a garbage bag from the outside, and it is natural that the odor from the garbage does not accumulate in the box body 1. This is to provide ventilation. The reason why the front center wall plate 8b is made detachable is to facilitate the cleaning operation inside the box body 1. As an attaching / detaching means, for example, as shown in FIG. 6, an L-shaped piece 16 is attached to the lower frame rod 5, and a horizontal rail 17 at the lower end of the front center wall plate 8b is attached to the upper side surface of the L-shaped piece 16. Pushing in from above, hook portions 15 are further provided on the left and right of the upper end of the front center wall plate 8b, and the hook portions 15 are detachably hooked on the upper frame rod 6.

As shown in FIGS. 3 and 4, inside each of the left and right side wall plates 10 and 11, a bridge is provided between the front and rear pillars 4a constituting the U-shaped side frame 4. The lid supporting leg 2 is pivotally supported on the left and right upper frame rods 6 so as to be swingable in the front-rear direction about a shaft 18. Fig. 5
As shown in the figure, a shaft support plate 19 is vertically fixed near the center in the front-rear direction of the upper frame rod 6 by welding or the like, and the shaft 18 is horizontally fixed to the inner surface side of the shaft support plate 19 in a cantilever manner by welding or the like. I do. The axis 1
A screw 20 having a diameter smaller than the shaft diameter is provided in a stepped shape at the tip of the shaft 8. On the other hand, the lid supporting leg 2 is formed in an angle shape in which the two arms are connected at right angles, and a hub 21 is formed at the connection base thereof. The hub 21 is rotatably connected to the shaft 18 via a copper bush 22. The small-diameter screw 20 of the shaft 18 is inserted into the washer 23 and the spring 2 for locking.
Then, the nut 25 is tightened through 4. The stepped shaft 1
8 with the washer 23 interposed therebetween.
A gap can be formed between the end face 1 and the washer 23, and the lid supporting leg 2 can swing lightly with low friction in combination with the interposition of the copper bush 22.

The lid 3 for opening and closing the access opening 14 is integrally formed between the distal ends of the left and right lid support legs 2.2 pivotally supported inside the left and right side wall plates 10 and 11 as described above. It is stretched over. The lid 3 is formed of a steel plate or the like into a circular cross section along the inner surface side of the arc portion 4b of the U-shaped side frame 4, and a connecting piece 25 is welded before and after the inner surface near the left and right ends. It is fixed with. Thus, the lid 3 is supported by the left and right lid support legs 2 by connecting each of the connecting pieces 25 of the lid 3 to the bent portions 2a at the respective ends of the left and right lid support legs 2 with rivets or the like. A handle 34 is attached to the outer surface of the lid 3 near the front end. The lid supporting leg 2 may be formed of, for example, a fan-shaped plate or the like, instead of being formed in an angle shape by two arms.

In this case, the lid 3 is opened and closed around the shaft 18 through the swinging movement of the lid supporting leg 2 in the forward and backward directions, as shown by the phantom line in FIG. 2 and the closed position as shown by the solid line in FIG. It is free to move. When the lid 3 is opened to a certain angle and its center of gravity is shifted backward from the shaft 18, the lid 3 can be opened lightly using its own weight. When the lid 3 is closed, if its center of gravity is closed to a certain angle located in front of the shaft 18, the lid 3 can be closed using its own weight thereafter.

When the lid 3 is opened, there is a danger that a finger may be pinched between the front end 3a of the lid 3 and the upper end of the front wall plate 8. To prevent this, close the front ends of the left and right upper frame rods 6 near the front end. Is a stopper 26 having a trapezoidal cross section made of a rubber material or the like having excellent cushioning properties.
When the lid 3 is closed, the lid supporting leg 2 comes into contact with the upper surface of the stopper 26 so that a gap 27 is formed between the front end 3a of the lid 3 and the upper end of the front wall plate 8. The gap 27 is set to about 1 to 2 cm, which is slightly larger than the thickness of a normal person's finger. When the lid 3 is opened, the lid supporting legs 2 hit the stoppers 28 attached to the rear ends of the left and right upper frame rods 6 so that the lid 3 cannot be opened any more.

However, when the lid 3 is opened and closed, there is a concern that the garbage bag P in the box body 1 may be caught in the lid supporting leg 2. Therefore,
The left and right upper frame rods 6 are provided on the left and right sides of the inside of the box main body 1 so as to separate the garbage bag intrusion prevention wall 30 made of a metal mesh plate, punching metal, or a blind wall plate from the lid supporting leg 2 and the inside of the box main body 1.
Are fixed to each by welding or bolts. In addition, a garbage bag intrusion prevention wall 31 made of the same plate material as described above is provided behind the inside of the box body 1 so that the garbage bag P is not caught in the rear end portion 3b of the lid 3 when the lid 3 is opened and closed. Is fixed to the rear upper frame rod 6 by welding or bolts so as to separate at least the rear end 3b of the lid 3 in the open position from the inside of the box body 1. However, the heights of the left and right and rear refuse bag intrusion prevention walls 30 and 31 are set so as not to interfere with the inner surface of the lid 3.

When the garbage bag intrusion prevention walls 30 are provided on the left and right inside the box body 1 as described above, as shown in FIG. 3, between the left and right garbage bag intrusion prevention walls 30 and the left and right side wall plates 10. Each of the lid support legs 2 can secure the lid support leg storage space 32 that swings back and forth without interfering with the garbage bag P in the box body 1, and the garbage bag can be prevented from being caught by the lid support leg 2. Further, a garbage bag intrusion prevention wall 31 is also provided inside the box body 1 behind.
