Description

[Detailed Description of the Invention] This invention relates to a lid opening/closing device for garbage collection boxes installed in urban areas, housing complexes, etc.

In this type of collection box, several households jointly put their garbage in, and the collection truck that makes regular rounds lifts the storage box with a crane, opens the bottom plate, and loads the garbage into the collection truck. It uses a transshipment system, and is widely used because it is efficient at collecting garbage, but it is large and usually made of metal. Therefore, the lid for opening and closing the garbage inlet is also large and heavy, making the garbage loading operation that involves opening and closing the lid a nuisance.

In view of this, the present inventor first proposed a foot-operated lid opening/closing device in which the lid can be opened and closed by pressing a foot pedal (see Publication No. 1973-6731).
However, it had the disadvantage of a very complicated structure.

Therefore, the object of this invention is to provide a lid opening/closing device for a collection box that has a simple configuration and allows easy loading of garbage. The gist of this is that the stopper rod is rotatably attached to the lid that is pivotally supported on the main body of the collection box, and the stopper rod is engaged with the lid depending on the degree of opening of the lid. It has a locking plate having a matching groove, a stopper lever release plate that is released by pushing upward the stopper rod that is locked in the engagement groove of the locking plate, and a push button that pushes up the stopper lever release plate. The lid opening/closing device includes a device for pushing up a release plate. Therefore, when the lid body is opened to a desired opening degree by hand, the stopper rod is engaged with the engagement groove, and the lid body is held at the desired opening degree.
Garbage can be thrown in, and after the garbage has been thrown in, when the push button of the release plate pushing device is pressed, the stopper lever release plate moves and the stopper rod locked in the engagement groove is removed. Therefore, the lid is closed by its own weight. That is, it is easy to maintain the lid in an open state and operate it when closed, and the structure is simple, so that the above-mentioned problems can be achieved.

Examples of this invention will be described below with reference to the drawings.

In FIG. 1, a bottom cover (not shown) is pivotally supported on the bottom of the collection box body 1, and when the lock mechanism is removed, the bottom cover is configured to rotate around the support shaft and open the bottom. .

A hook part 2 for hoisting the collection box is provided on the upper surface of the collection box main body 1, and an input port 3 is provided on both sides of the hook part 2.

Each of the lids 4, 4 is disposed in the inlet 3, and one end of the lids 4, 4 is rotatably supported on the collection box body 1.

The lid opening/closing devices 5, 5 open and close the lids 4, 4, and are composed of a stopper lever 6, a locking plate 7, a stopper lever release plate 8, and a release plate push-up device 9. (See Figures 2 and 3) One end of the stopper lever 6 is rotatably attached to the back surface of the lid 4, and the other end is attached to a locking plate 7 as described below.
It is arranged in a sliding space 11 formed by the upper surface and the inner surface of the edge 10 of the inlet 3, and the other end of the stopper rod 6 moves within this space 11 as the lid 4 is opened and closed. .

The locking plate 7 has fixing parts 12, 12 at both ends fixed to the edge 10 of the input port 3, and the other end of the stopper rod 6 is locked to the upper end of the locking plate 7 according to the degree of opening of the lid 4. An engagement groove 13 is provided. In this embodiment, three engagement grooves 13 are provided,
As the lid body 4 is opened and closed, the other end of the stopper lever 6 moves within the space 11, and is locked in the engagement groove 13 by the weight of the stopper rod 6, so that the lid body 4 is held at that opening degree.

The stopper lever release plate 8 is disposed parallel to the locking plate 7, and is moved upward by a release plate pushing device 9 described below, and the stopper lever 6 is locked in the engagement groove 13 at its upper end. to disengage it.

The release plate push-up device 9 moves the stopper lever release plate 8 upward, and is formed on a protrusion 14 provided on the locking plate 7 and the stopper lever release plate 8 so that the protrusion 14 is inserted. and a long hole 15,
The long hole 15 has an inclination α with respect to the horizontal direction. Push button 1 of this release plate pushing device 9
The tip of 6 is fixed to the bent end portion 17 of the stopper lever release plate 8, and the head 18 side protrudes outside the collection box body 1, and the back surface of the head 18 and the collection box A return spring 20 covered by a protective cover 19 is arranged between the main body 1 and the main body 1.

Therefore, when the pushbutton 16 is pressed, the stopper lever release plate 8 is released as shown by the two-dot chain line in FIG.
moves obliquely upward along the elongated hole 15, and
When the push button 16 is released, the spring pressure of the return spring 20 releases the stopper lever release plate 8.
And the push button 16 is returned to its original position.

In addition, in this embodiment, the release plate pushing device 9
The locking plate 7 is provided with a protrusion 14, and the stopper lever release plate 8 is formed with a long hole 15;
Alternatively, the long hole 15 may be formed in the stopper lever release plate 8, and the protrusion 4 may be provided in the stopper lever release plate 8.

In the above configuration, when the lid body 4 is opened to a desired opening degree by hand, the other end of the stopper rod 6 moves within the sliding space 11, and the locking plate 7 corresponds to the opening degree.
The lid body 4 is locked in the engagement groove 13 of the stopper rod 6.
The opening is maintained at the desired degree.

Then, when the push button 16 is pressed after the garbage has been input, the stopper lever release plate 8 is released from the elongated hole 1.
5 and move upward along 2 to 2 and 3.
As shown by the dotted chain line, the stopper rod 6 that is engaged with the engagement groove 13 of the engagement plate 7 is pushed up and disengaged, and the lid 4 closes under its own weight, preventing the lid 4 from opening and closing. It's easy to do.

As described above, this invention provides a stopper lever, a locking plate having an engagement groove in which the stopper rod engages, a stopper lever release plate that disengages the stopper rod, and a stopper lever release plate that moves the stopper lever upward. Since the device is constructed with a release plate pushing device that pushes up the device, the structure is simple, and the lid body can be opened and closed easily, so that the work of putting in the garbage can be done easily.

Further, this invention can be applied to conventional garbage collection boxes whose lids are opened and closed by hand by attaching a predetermined stopper rod or the like without making any major design changes.
