A toilet includes a body, a lid assembly, and a hinge assembly. The body includes a bowl and a body top surface. The body top surface is contiguous with the bowl. The lid assembly includes a lid. The lid is configured to cover the bowl. The hinge assembly is operable between a first position and a second position. The hinge assembly includes a mounting base coupler, a lid coupler, a first hinge member, and a second hinge member. The mounting base coupler is coupled to the body top surface. The lid coupler is coupled to the lid. The first hinge member is coupled to the mounting base coupler and the lid coupler. The second hinge member is coupled to the mounting base coupler and the lid coupler. The lid covers the bowl when the hinge assembly is in the second position.

A joint arrangement for the pivotable mounting of a lid, a seat or a seat/lid fitting about a pivot axis on a ceramic sanitary article, which joint arrangement comprises an elongate fastening element which is intended to be arranged on the sanitary article, a bearing element having a passage bore through which the fastening element is intended to engage, and a damper element which damps the pivoting movement and has a connecting element, which likewise has a passage bore into which the fastening element engages or through which said fastening element engages and which fits on the bearing element in the assembled position, wherein the bearing element has a retaining portion which receives the connecting element in a form-fitting manner.

A quick-release and quick-installation hinge assembly includes a hinge to which a toilet lid is rotatably connected, a key plate fixed on a toilet bowl, and a limiting member. The hinge is fixedly provided with a hinge base fitted with the key plate. The hinge base and the key plate are in insertion fit in a lateral direction. The limiting member is provided with an inserting portion. The key plate is provided with an inserting hole that is in insertion fit with the inserting portion for position limitation. The inserting portion is fitted with the inserting hole for position limitation to prevent the hinge base and the key plate from being separated from each other in the lateral direction. The inserting portion penetrates through the inserting hole. The quick-release and quick-installation hinge assembly realizes a stable convenient connection structure between the hinge base of the hinge and the key plate.

A friction hinge with its motion restricted in one pivoting direction includes a support member, a restricting module, and a pivot member. The restricting module is mounted on the support member. The restricting module has an air flow opening. The pivot member is pivotable relative to the support member and the restricting module. A regulating chamber is defined between the pivot member and the restricting module. When the pivot member is pivoted in one direction, a pressure in the regulating chamber is increased and the restricting module is actuated to reduce size of the air flow opening, increasing the resistance to pivoting of the pivot member in this pivoting direction.

A sitting toilet cover plate support capable of being quickly released and assembled comprising a cover plate support, a rotating shaft, a first hinge, a second hinge, a support cover, a screw rod, a lining ring and an opening nut; an isosceles trapezoid hole is formed in the cover plate support, and a guide groove limiting hole is formed in the top edge of the isosceles trapezoid hole; the rotating shaft is provided with ribs capable of limiting the cover plate support, and an annular groove capable of limiting the hinge is formed in the guide groove limiting hole; the first hinge and the second hinge are respectively arranged on the two sides of the guide groove limiting hole; the first hinge and the second hinge are both 6-shaped hinges.
