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. In FIGS. 1 and 2, the refuse collection box includes a box body 1, left and right lid support legs 2, and a lid 3. The box body 1 includes a pair of left and right side frames 4 and 4 formed by bending a metal pipe or the like into a U-shape, and a shaped steel member and the like formed on the same plane on the bottom side between the left and right side frames 4 and 4. A frame 7 is composed of front, rear, left, and right lower frame rods 5 and upper, lower, left, right, and upper frame rods 6 laid in parallel above the lower frame rod 5 between the left and right side frames 4. A front wall plate 8, a rear wall plate 9, left and right side wall plates 10 and 11, a top wall plate 12 having an arc-shaped cross section, and a bottom wall plate 13 are respectively stretched over and fixed by screws or welding. A garbage bag inlet / outlet 14 is formed between the left and right side wall plates 10 and 11 between the front of the upper wall plate 12 and the upper end of the front wall plate 8.

The front wall plate 8 is composed of 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.
8a is fixed, and the front center wall plate 8b is detachably attached. If the front center wall plate 8b is made of a mesh plate material, it is easy for the collection vehicle to check the presence or absence of a garbage bag from outside, and natural ventilation so that odors from garbage do not accumulate in the box body 1. Can be performed. 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. Push in from above, and then the front center wall plate 8
b, hook portions 15 are provided on the left and right of the upper end.
5 is detachably hooked on the upper frame rod 6.

As shown in FIGS. 1, 2 and 4, inside the left and right side wall plates 10 and 11, the U-shaped side frame 4 is provided between the front and rear pillars 4a. The lid supporting leg 2 is pivotally supported on the upper frame rod 6 so as to be swingable in the front-rear direction about the axis 18. At the time of this shaft support, as shown in FIG. 5, 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 1 is mounted on the inner surface side of the shaft support plate 19.
8 is horizontally fixed in a cantilever manner by welding or the like. A screw 20 having a diameter smaller than the diameter of the shaft 18 is attached to the tip of the shaft 18 in a stepped manner. On the other hand, the lid support leg 2 is formed in an angle shape in which the two arms are connected at right angles, and a hub 2 is formed on the connection base.
1 and the hub 21 is attached to the shaft 18 by the copper bush 2.
2 is rotatably inserted through the small screw 20 of the shaft 18.
, A nut 25 is tightened via a washer 23 and a spring 24 for preventing loosening. A gap can be formed between the end face of the hub 21 and the washer 23 by interposing the washer 23 on the step portion of the stepped shaft 18,
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 stretched 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. Is established. The lid 3 is formed of a steel plate or the like to have an arc-shaped cross section along the inner surface side of the arc portion 4b of the U-shaped side frame 4,
The connecting pieces 26 are fixed by welding or the like before and after the inner surface near the left and right ends, respectively. Thus, the lid 3 is supported by the left and right lid support legs 2 by connecting each of the connecting pieces 26 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 33 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 can swing open and close around the shaft 18 between the open position shown by the imaginary line and the closed position shown by the solid line in FIG. is there. When the lid 3 is opened to a certain angle and its center of gravity is shifted rearward from the shaft 18, the lid 3 can be opened lightly by utilizing the own weight of the lid 3 thereafter. When the lid 3 is closed, the center of gravity is closed to a certain angle located forward of the shaft 18, and thereafter the lid 3 can be closed lightly by using its own weight as in the case of opening.

However, when the lid 3 is closed by utilizing its own weight, there is a risk 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. Therefore, between the upper end of the front wall plate 8 of the box body 1 and the front end 3a of the lid 3 in the closed state.
The box body 1 is formed so that a gap 27 for preventing finger pinching is formed.
A stopper 29 is provided between the cover 3 and the cover 3. For example, as shown in FIG. 1, the stopper 29 is attached to the front end of the upper frame rod 6 on which the lid supporting leg 2 is pivotally supported. A stopper 29 with a trapezoidal cross section is attached with screws, etc.
When the lid 3 is closed, the lid supporting leg 2 comes into contact with the upper surface of the stopper 29, 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 human finger. According to the dimension setting of the gap 27 of such a degree, it is possible to ensure the prevention of intrusion of dogs and cats. Incidentally, when the lid 3 is opened, the lid supporting legs 2 hit against the stoppers 31 attached to the rear ends of the upper frame rods 6 on the left and right sides, respectively, so that the lid 3 is not further opened.

Instead of mounting the stopper 29 for preventing finger pinching on the side of the upper frame rod 6, the stopper 29 may be mounted on the side of the lid supporting leg 2 so that the stopper 29 abuts on the upper frame rod 6 when closed. . As shown in FIG.
As 9, there are two types of stoppers 29 a with a difference in elevation.
When the stopper 29a made of rubber or a plastic material on the taller one wears with long-term use, a thin rubber film 32 is formed only on the upper surface on the shorter side. It is also possible to ensure that the stop function is exerted by the metal stopper 29b so that safety can be ensured over a long period of use .

[0014]

As described above, according to the present invention, a stopper is provided between the box body and the lid, and when the lid is closed, the stopper causes the front end of the lid and the upper end of the front wall plate of the box body to be closed. A gap for preventing finger pinching is formed between them, so the lid with a large load that can be opened and closed around its axis using its own weight, especially large garbage bins that can be stored in large quantities, can be safely closed. be able to. Further, the odor generated from the garbage in the garbage bag can be released from the garbage through the gap to the outside of the box without being trapped in the box main body, which is advantageous in this respect.
