[2] Embodiments of the open/close receiving device and the container including the open/close receiving device of the present invention will be further described including forms other than the above.

(1) The open/close receiving device of the present invention includes a cover portion, an open/close lid, and a drive mechanism.

(2) The cover part has an opening for receiving an object such as dirt.

The opening is opened upward, and it is desirable that the whole is opened upward in order to make it difficult to see the lower inside from the diagonally upper side of the opening.

Objects such as dirt are received downward from the opening of the cover.

The opening may have, for example, a rectangular shape, or a rectangular shape having a slightly outwardly convex rounded shape, but is not limited thereto.

The cover part is located, for example, at the upper part of the container (for example, the upper part of the entire container or the upper part of the part of the container) having the container that stores the object such as filth. The received object such as filth can be accommodated in the accommodating portion located below the opening, but is not limited to this.

The cover and the outer shell of the container can be made of, for example, synthetic resin, but are not limited to this.

In a predetermined horizontal direction (preferably in the front direction, that is, a horizontal direction orthogonal to the direction in which an object such as filth is thrown into the opening), the width of the cover or the width of the container is 1. It is preferably 1 to 1.8 times. It is more preferably 1.1 to 1.6 times.

In addition, the cover part is removable from other parts (for example, the cover part constitutes a part of the container such as the upper part of the container, and the other part of the container such as the lower part of the container). It can be attached to and detached from a portion), but is not necessarily limited to this.

The cover part, the container, or other object has a chute (a downward slope) for guiding an object, such as filth, which is located below the opening part and received downward from the opening part, to the accommodation part or other required place below. A guide part such as a guideway) can be provided.

Such a guide portion such as a chute prevents (blocks) a required portion such as a storage portion that stores an object such as dirt from being visible from above the cover portion when the opening portion is open. Can be

In addition, when the cover part is removable from other parts, the height of the cover part is suppressed (for example, in order to increase the capacity by increasing the height of the accommodating part or the like to be coupled downward). In addition, the entire length of the slope of the guide part such as the chute (downward slope guide path) is made as long as possible to reliably guide the object to the required place and prevent the lower required place from being visible from above the cover through the opening. In order to increase the height, the lower portion of the guide portion may project below the cover portion. In this case, when the cover part is attached to another part, the predetermined part receives a predetermined action such as pressing due to the attachment, the inclination angle of the guide part such as the chute becomes large, and the lower part protrudes below the cover part. When the cover is removed when the cover is in use and the cover is removed, the angle of inclination of the guide such as the chute is small (including reverse tilt) or horizontal so that it does not project downward from the cover due to the balance of its own weight, etc. It can be made movable so that it can be placed on a horizontal plane.

(3) The open/close lid includes a lid that opens and closes the opening.

The outer portion of the lid portion with respect to the cover portion in a state in which the opening is closed has an outwardly convex curved shape such as upward (for example, a curved plate shape, particularly, a curved plate shape having a substantially constant thickness). The opening can be opened and closed by rotating a predetermined angle (for example, forward rotation and reverse rotation at a predetermined angle) about a rotation axis located on the inner side of the lid.

The lid portion is lower than the height position of the upper surface portion of the cover portion (preferably, the opening portion in the upper surface portion of the cover portion is in any state such as the opened and closed states and the opening/closing process). Lower than the height of the outer circumference). The lid is opened/closed when the luggage is placed on the cover near the opening, or when the lid is accidentally or intentionally prevented from being opened/closed. This is to avoid causing a failure or the like.

The shape of the lid portion of the outer portion with respect to the cover portion when the opening is closed is, for example, a shape corresponding to a predetermined central angle portion of the outwardly convex cylindrical curved surface (for example, a curved plate shape), and For example, the lid part can rotate forward and backward about a horizontal rotation axis that is located, for example, corresponding to the center axis of the cylindrical curved surface. Alternatively, for example, the lid portion can rotate forward and backward around a horizontal rotation axis that is located below and has a shape corresponding to a part of a spherical surface (for example, a curved plate shape) and that corresponds to the central axis of the cylindrical curved surface. Can be something. However, it is not limited to these. The rotation axis located on the inner side of the lid is not necessarily horizontal.

The opening/closing lid may have, for example, a lid portion and a structural portion for rotatably supporting the lid portion, or may be the lid portion itself.

The opening/closing lid body, when receiving an object such as dirt downward from the opening of the cover while the opening of the lid is open, the received object reaches a required portion such as the accommodation section of the container. It does not hurt to do. Regarding this, it is necessary that not only the lid portion itself is not harmed, but also portions other than the lid portion are not harmed. For example, when the opening/closing lid body has a structural portion that supports the lid portion with respect to a rotation support structure centering on a rotation axis such as a rotation shaft, such a structural portion is provided on both sides in the width direction of the opening. By providing the support plate or the like, it is possible to prevent the object received from the opening of the cover from reaching the required portion such as the storage portion of the container.

(4) The drive mechanism is for driving the opening/closing lid to open and close the opening with the lid, and is provided in the cover. In addition, it is not always necessary that the entire drive mechanism is provided in the cover portion.

The drive mechanism may be provided with a power source, or may be provided separately. In order to prevent the width of the cover portion from increasing, it is desirable that the drive mechanism (particularly, the drive mechanism including the power source) be located behind (or in front of) the opening in the cover portion.

As the power source, for example, an electric motor and a necessary speed reducer can be used, but the power source is not limited thereto. For example, a signal input from a signal generating unit such as a sensor or various switches provided on the cover or the like for detecting an object or the like is rotated forward by a predetermined rotation angle (or a predetermined number of rotations) to open the lid via a drive mechanism. It is possible to use various electric motors provided with a control circuit that controls to rotate in a reverse direction after a lapse of a predetermined time so as to close the lid via the drive mechanism and a required reduction gear.

As an example of the drive mechanism, the power source and the opening/closing lid are connected directly or via the swing arm, and the swing arm is rotated by a predetermined angle to open the lid, and the swing arm is rotated in the opposite direction by a predetermined angle. By doing so, the lid can be closed. It is also possible to alternately repeat the open state and the closed state by rotating the lid portion in a fixed direction by 90 degrees, for example.

It is preferable that a torque limiter is interposed between the opening/closing lids of the drive mechanism to prevent damage to the power source and other drive mechanisms due to an excessive load.
