US Patent 11045054 Cover device, toilet cover assembly and toilet

A cover device that mounts to a body of a toilet is provided. The cover device includes a cover rotatably mounted to the toilet, a spring coupled to a sleeve of the cover, and a damper coupled to the sleeve of the cover and having a bearing coupled to the spring. The cover is designed to rotate upward relative to the body of the toilet to a generally vertical position to place the spring in a relaxed position. The cover is designed to rotate downward relative to the body of the toilet to a generally horizontal position to place the spring in a compressed position, thereby allowing a maximum elastic force in the spring in the compressed position to rotatably adjust the cover upward relative to the toilet.
