Will be configured.

Next, the operation of this embodiment will be described.
In a normal state, that is, when the outer lid 2 is closed, the pair of inner lids 3, 3 is closed. Also the cam body
31 is in a state where its minor axis direction is oriented in a substantially horizontal direction.

When the pedal 6a is depressed, the pedal shaft 6 rotates clockwise around the axis, so that the opening / closing bar 9 rises and the outer lid 2 opens. While the pedal shaft 6 is rotating, the one-way clutch 31a idles, so that the cam body 31 cannot rotate.

Then, with the outer lid 2 open, dust is placed on the pair of closed inner lids 3, 3.

When the pedal 6a is released, the weight of the outer lid 2 and the weight of the opening / closing bar 9 and the force of being pulled by the spring 8 cause the opening / closing bar 9 to descend. Since the pedal shaft 6 rotates counterclockwise while the open / close bar 9 is descending, the one-way clutch 31a rotates together with the cam body 31. At this time, the cam follower 33 that is in contact with the cam body 31 is
The rotation of 31 moves outward along the groove 5c. The outward movement of the cam follower 33 is performed until the cam body 31 rotates about 90 ° from the normal, that is, until the minor axis direction of the cam body 31 faces the substantially vertical direction.

When the cam follower 33 moves outward, the pair of links 35, 35 open about the support shaft 34, and the transmission member 36 swings about the rotation shaft 37 as a center of rotation. Inner lids 3 and 3 open in a substantially horizontal direction. At this time, the dust placed on the pair of inner lids 3,3 easily falls inside the dust storage portion.

Further, when the pedal shaft 6 rotates and the cam body 31 rotates about 90 ° or more than usual, the cam follower 33 moves into the groove.
When the cam body 31 rotates about 180 ° from the normal direction as it moves inward along 6c, the inward movement of the cam follower 33 ends, and the pair of inner lids 3 and 3 are completely closed. The state is entered, and the series of operations ends.

As described above, in this embodiment, since the pair of inner lids 3, 3 are operated in the substantially horizontal direction by the opening / closing means, the pair of inner lids 3 and 3 are operated.
The dead space created by opening and closing 3,3 can be reduced, and as a result, a sufficient amount of garbage can be stored.

In this embodiment, the cam body 31 is the transmission member 36.
Since the pair of inner lids 3 and 3 are operated via the subordinate transmission member 38 and the groove 6c regulates the open position and the closed position of the pair of inner lids, the pair of inner lids 3 and 3 is not opened. It is possible to reduce the sound generated when the ends of the inner lids 3, 3 come into contact with each other when closed.

[0055]

In the waste container according to the first aspect of the present invention, since the pair of inner lids are operated in a substantially horizontal direction by the opening / closing means, the dead space formed by opening / closing the pair of inner lids can be reduced. As a result, a sufficient amount of garbage can be stored.

According to a second aspect of the present invention, in addition to the effect of the first aspect, the cam body operates the pair of inner lids via the transmission member, and the position restricting member serves to open the pair of inner lids. Since the position of the inner lid is regulated, the sound generated when the ends of the inner lid hit each other when the pair of inner lids is closed can be reduced.
