Description

[Detailed description of the invention] This invention was created for the purpose of preventing the rotary lid from malfunctioning in a trash can with a rotary lid made of a molded product. In a garbage box with a rotary lid, which is formed by removably covering a lid frame 3 with a lid 2 rotatably fixed on a shaft, shaft pins protruding from both side walls of the lid frame 3 are formed on the short shaft 4. In addition, a pipe 5 was loosely fitted into the shaft hole 6 of the rotary lid 2, and the length of the pipe 5 was set to maintain a constant distance between both side walls of the lid frame 3, and the rotary lid 2 was loosely fitted into the pipe 5. This is a device for preventing faulty rotation of a rotary lid in a garbage box with a rotary lid, which is fitted and held on the short shaft 4 of the lid frame 3 in the above-mentioned state.

Conventionally, a garbage can with a rotating lid has a rotating lid A as shown in Fig. 1.
Since the inner wall C portion of the lid frame B that rotatably pivots the rotary lid A and the inner wall C of the lid frame B is curved in the direction shown by the arrow,
Since the rotary lid A is pressed against the lid without leaving an appropriate gap, there is a drawback that the rotary lid A cannot be rotated smoothly.

As one means to eliminate this drawback, we have prepared this lid frame B in advance.
The width of the rotary lid A is narrowed by taking the dimension narrowed by the curvature of the inner wall C of the lid. Even if this could be done, the gap between the inner wall C of the lid frame B and the inner wall C of the lid frame B becomes wider toward both ends of the rotary lid A, resulting in an unsightly result in which the inside of the trash can can be seen through the gap, which is not practical.

This invention solves the above-mentioned drawbacks of conventional products with an extremely simple structure, and includes a pair of short shafts protruding on the same line from inside both side walls of the lid frame that pivots the rotating lid, and A shaft hole is drilled at the shaft stop of the rotary lid, and a pipe with a diameter that can be loosely fitted into the shaft hole of the rotary lid is prepared, and the length of this pipe is such that the proper spacing between both side walls of the lid frame can be maintained. While loosely fitting the shaft hole of the rotary lid into this pipe, fit both ends of the pipe to the short shaft of the lid frame, and use this pipe to connect the rotary lid and the shaft rod for rotation of the lid frame. At the same time, the two side walls of the lid frame act as supports to prevent the two side walls of the rotary lid from coming into pressure contact with the two side walls of the rotary lid, causing rotation failure.

Therefore, this invention has the advantage that the rotation failure of the rotary lid, which was a drawback of the conventional product, can be completely eliminated by simply adding one pipe.

In addition, when assembling, the shaft pin end is not lengthened as in conventional products, but is protruded from the short shaft, and while the pipe is loosely fitted into the shaft hole of the rotary lid, both ends of the pipe are connected to the short shaft of the lid frame. It is a practical device that is extremely easy to work with and can be commercially available at low cost since it is forcefully fitted and held.

Embodiment The trash can 1 is comprised of a trash can 1 having a desired volume, a rotary lid 2 formed into a chevron-shaped side surface, and a lid frame 3. The lid frame 3 is removably covered with the trash can 1.

Both side walls of this lid frame 3 are formed into a chevron shape to match the shape of the rotary lid 2, and a short shaft 4 is provided protruding on the same line inside the both side walls.

Further, a shaft hole 6 is bored in the same line on both side walls of the rotary lid 2.

A separate pipe 5 is prepared, and the diameter of this pipe is the diameter of the shaft hole 6 of the rotary lid 2.
The length is such that when the rotary lid 2 is placed between both side walls of the lid frame 3, the gap between the two is appropriate. Shape it to a length that will act as a support.

The shaft hole 6 of the rotary lid 2 is loosely fitted into this pipe 5, and in this state, the short shaft 4 of the lid frame 3 is fitted and held in both end holes of the pipe 5, and the pipe 5 is rotated with the support. Used for both shaft purposes.
