[Effect]

Next, how to use the trash can configured as described above will be explained.

Now, when the pedal 9 is depressed from the state where the lid 10 is closed as shown in FIG. 7a, the inner box 6 is moved as shown in FIG. is rotated. Based on this rotation, the rear opening edge of the inner box 6 pushes up the cam piece 11 and opens the lid 10. At this time, the actuating member 12 attached to the rear surface 10a of the lid 10 is kept suspended by its own weight.

When the lid 10 is opened to the upright position with the pedal 9 fully depressed, the lid 10 further rotates rearward with the momentum with which it has been rotating. When the lid 10 is in the position shown in FIG.
comes into contact with the rear surface 10a of the lid 10, and the actuating member 12 tilts forward. At this time, the lower end of the actuating member 12,
That is, the engaging portion 12a of the actuating member 12 is in contact with the rear surface of the inner box 6 below the engaging protrusion 8 of the inner box 6.

Then, with the lid 10 fully open,
When the pedal 9 is released, the inner box 6 returns to its original state due to its own weight, making it possible to store garbage. When the inner box 6 returns to its original state, the engaging portion 12a of the operating member 12
slides upward on the rear surface of the engaging protrusion 8 of the inner box 6 and comes into contact with the rear surface of the inner box 6 above the engaging protrusion 8, as shown in FIG. 7d.

When the actuating member 12 slides on the engagement protrusion 8 described above, if a slight pressing force is to be applied to the rear surface 10a of the lid 10, this pressing force can be suppressed by giving the actuating member 12 some flexibility. The pressure is not strong enough to rotate the lid 10 in the closing direction, and the lid 10 is held completely open.

Next, when the pedal 9 is depressed again to close the lid 10, the inner box 6 rotates in the same manner as described above. Then, the engaging portion 12a of the actuating member 12 comes into contact with the engaging protrusion 8 of the inner box 6, which is moving upward, as shown in FIG. 7e. Subsequently, the actuating member 12 is pushed upward by the engaging protrusion 8 and applies a force to the rear surface 10a of the lid 10 via the abutting portion 14 in the direction of closing the lid 10. As a result, the lid 10 rotates in the closing direction, and after passing the vertical position, the lid 10 is rotated in the closing direction, and after passing the vertical position,
It rotates and closes under its own weight as shown in .

After closing, the inner box 6 and the operating member 12 also return to their original states and wait for the opening/closing operation by depressing the pedal 9 again.

Note that the present invention is not limited to the above-mentioned embodiment. For example, as shown in FIG. After formation,
It may also be applied to a structure in which the rotation regulating member 17 is bent in an L-shape at the front. In this case, if the same pedal operation as described above is performed, the engaging portion 12a of the actuating member 12 is
have the same effect to open and close the lid 10. Moreover, in this case, for some reason, the operating member 1
The shaft 13 that supports the actuating member 12 becomes hard.
Even if the lid 10 does not rotate smoothly and is already tilted when the lid 10 is closed as shown in FIG. This restricts further forward rotation. Therefore, even if the pedal 9 is depressed in the state shown in FIG. 10a and the inner box 6 rotates rearward as shown in FIG. I am going to be
As a result, the engaging portion 12a of the actuating member 12 and the inner box 6
The engaging protrusion 8 does not engage with the engaging protrusion 8 when the lid 10 is open. Therefore, there is no fear that the lid 10 will not open.

Further, as shown in FIG. 11, the upper end of the actuating member 12 is bent into an L-shape to form a protruding piece 18, and the rear side of the upper surface 18a of the protruding piece 18 is used as an abutting part. may be brought into contact with the rear surface 10a of the lid 10.

Furthermore, as shown in FIGS. 12a and 12b, the actuating member 12 is rotatably supported on the rear surface 10a of the lid 10 at a position slightly upward when the lid 10 is closed, and is provided to protrude to form an engaging protrusion 19, and its upper end is used as an abutting part. Then, as the lid 10 rotates as shown in FIG. 12b, the actuating member 12 is tilted so that the contact portion of the engaging protrusion 19 comes into contact with the rear opening edge of the outer box 1. You can do it like this.

〔Effect of the invention〕

As described in detail above, the garbage can lid opening/closing mechanism of the present invention requires only one step of stepping on the pedal without using any hands.
By repeating a simple operation, you can hold the lid in the open and closed positions even if you take your foot off, making it easy and sanitary to open and close the trash can lid. has.
