Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to means for automatically opening and closing a trash can lid fixed to the back of a door of a storage having a front opening door by opening and closing the door. It is. 2. Description of the Related Art Conventionally, several such techniques have been proposed. For example, Japanese Utility Model Publication No. 55-11714,
-75301, actual opening 60-12503, etc.,
A drawback common to all cases is that the trash can is attached to the storage box partly on the door side and the other part is mounted on the inner wall of the storage box. Or use something easy to cut like a string.
The trash can body is attached to the back of the door, and the lid and the lid opening / closing member are attached to the inner wall of the storage, so if the doors are not in the correct position when the door is closed, the lid will not open or close properly or the lid will be eccentric It cannot be sealed. [0003] The trash can can be used by three simple operations of (the trash can is stored with the lid closed). Therefore, it is necessary to have a strong and hard-to-break structure. Complex structures, such as those known in the art, are fragile and costly, so they must be simpler, more durable, cheaper and fully functional. It is desirable that it can be installed only by specialists who require difficult installation operations and can be installed by general housewives. [0004] A trash can and a lid are integrated by a rotating shaft, and a function of opening the lid by a spring or a weight is provided. The lid is fixed to the back surface of the door, and the door is fixed. When opened and closed, the lid was automatically opened and closed by the top plate or lower plate of the hangar. DESCRIPTION OF THE PREFERRED EMBODIMENTS A trash can lid fixed to the back of a storage door has a function of opening by a hinge, a spring, a weight, and the like. Either a top plate such as a sink bottom installed at a position, or a lower plate such as a bottom plate of the storage bin installed at a lower position of the trash can, the lid against a force such as a spring or a weight. Is closed, and when the door is opened, the trash can comes out integrally with the door, and the lid is configured to be opened by the force of the spring, the weight, or the like such that the front is on the opening side. Embodiments of the present invention will be described with reference to the drawings based on embodiments. In the partially cutaway front view of FIG. 1 and the top view of FIG. 2, the lid 4 of the trash can 3 fixed to the back of the door 2 that opens forward by the hinge 1 is a rotating shaft 5.
About to be opened by the force of the spring 6. The spring plate 7 fixed to the lid 4 contacts the bottom surface of the sink 8 and presses the lid 4 in a sealing direction. FIG. 3 shows a state in which the door 2 is opened. The trash can 3 fixed to the door 2 comes out integrally with the door 2. At this time, the lid 4 sealed at the bottom of the sink 8 via the spring plate 7 is opened,
It is opened by the force of the spring 6 so that the front side is on the open side.
After throwing the trash into the trash can 3, when the door 2 starts to close, the lid 4
1 starts to close by hitting the bottom surface of the sink 8, and when the door 2 is closed to the end, returns to the state of FIGS. 1 and 2, and the lid 4 is closed by the spring plate 7. When there is no sink 8 or when the sink 8 and the lid 4 are separated, another plate may be installed instead of the bottom surface of the sink 8. As shown in FIG. 4, the spring 6 can be replaced by a weight 9 having the same force. [0007] In the second embodiment shown in FIG.
Is fixed to the door 2A, and the lid 4A is about to be opened by the force of the spring 6A about the rotation shaft 5A. Lid 4
A third rotating shaft 12 is provided at the lower end of the connecting rod 11 connected by the second rotating shaft 10 near the rotating shaft 5A of A, and is rotatably connected to the U-shaped lever 13. The U-shaped lever 13 is rotatable about a fourth rotation shaft 14 protruding from the lower surface of the trash can 3A at substantially the center thereof. The other end of the U-shaped lever 13 has a hemispherical scalloped shape, and is entirely made of a resilient material. Figure 5 shows the door closed.
The U-shaped lever 13 hits the bottom plate of the storage and rotates clockwise to close the lid 4A. As shown in FIG. 6, when the door 2A is opened, the trash can 3A comes out of the storage, so that the U-shaped lever 13 rotates counterclockwise by the force of the spring 6A, and the front of the lid 4A is open. Opened like. Door 2
When the user begins to close A, the scoop-shaped portion of the U-shaped lever 13 is rotated clockwise by the bottom plate of the storage, and the lid 4 is closed.
A is closed. At this time, the lid 4A is sealed by the elasticity of the dogleg-shaped lever. The spring 6A can be replaced by a weight 9 as in the first embodiment. [0010] The present invention is configured as described above, and has the following effects. When the door of the storage is opened (the trash box comes out with the lid open), the trash is discarded, and when the door is closed (the trash box is stored with the lid closed), the trash disposal operation is easy.
It can be performed in a short time. Since the whole structure is simple and durable,
Hard to break and cheap. [0012] Since the whole is integrated, it is easy to attach it to the back surface of the storage. Since the lid is sealed, odor does not leak.
