This present invention with the new added structure improvements to a single spring hinge for automatically keeping a toilet seat open and raised in an upright vertical position at all times.

the previous single spring hinge which a patent had already been granted by the U.S. PTO (Publication Number U.S. Pat. No. 4,751,765 A (Application Filed Number U.S. Ser. No. 06/938,604) which mainly utilizes the tension adjustment stand, made of metal or plastic composite material, to preserve the original intended functions,
the spring hinge which includes a first member, a second member, a spring, a spring seat, a tensile adjustment seat, a tensile adjustment pin, a shaft, and two holding heads.

The holding heads each include a hollow hat and a set of slots radially extending to form a set of claws fixed inside the hollow hat, the central portion of the slots being inwardly concave and an opening whose diameter is slightly smaller than the diameter of the shaft.

Thus, the shaft penetrating through the opening is pressed and secured by the claws so as to prevent any withdrawal of the shaft from the opening.

The application relates to a seat device and a toilet. The seat device comprises a seat having an opening, a spray pipe having a nozzle and a blocking door pivotally mounted in the seat and used for blocking the opening; the blocking door is mounted in the seat through a pivot shaft, and the blocking door is capable of rotating around the pivot shaft; the nozzle has a storage state in which the nozzle is stored in a pipe body and an extension state in which the nozzle extends out of the pipe body; when the nozzle is in the storage state, the blocking door at least partially blocks in the opening; when the nozzle is in the extension state, the nozzle holds up the blocking door to make it rotate and open the opening, and the nozzle extends out of the opening. According to the seat device and the toilet disclosed by the application, the blocking door is pivotally mounted in the seat, and in both opening and closing processes of the seat, the blocking door can block the opening of the seat, so that a structure is simplified, convenient mounting is realized, and a function of preventing water dripping is provided.

An assembly of cooperatively hinged nested toilet seats of sizes downwardly graduated from smaller to larger, from a smallest top seat to a largest bottom first seat. Each of the relatively smaller seats nests within a declining inner seat contour of a relatively larger seat below it. An extension of the declining inner seat contour of each seat defines a downward seat flange, which is configured to extend within the rim of the toilet bowl when the seat is lowered. Each successively smaller seat has a downward seat flange which is configured, when the seat is lowered, to nest within and engage the inner perimeter of the seat opening defined by the downward seat flange of the seat below it. The cross-sectional profile of each of the nested toilet seats comprises the downward seat flange, which transitions into the declining inner seat contour, which transitions into a middle seat contour, which in turn transitions into an outer seat contour.

A toilet cover plate includes a cover plate body, including a channel and a body recess disposed on a top surface of the cover plate body and connected with the channel. The toilet cover plate also includes a flip cover disposed on the cover plate body and pivotally mounted in the body recess. When the flip cover is in an initial state, the flip cover is received in the body recess and covers an opening of the channel. The toilet cover plate also includes a holding mechanism disposed between the flip cover and the cover plate body and configured to keep the flip cover received in the body recess.

A lid and seat assembly for a plumbing fixture includes a housing, a lid, and a seat. The housing includes a generally planar front surface and a generally planar rear surface. The lid is pivotably coupled to the housing. The seat is pivotably coupled to the housing. The front surface and the rear surface meet at a first edge located at a first end of the housing and at a second edge at a second end of the housing. The front surface, the rear surface, the first common edge, and the second common edge cooperatively define a continuous surface profile configured to facilitate single-wipe cleaning of the housing.
