A fastening assembly is configured to couple a toilet seat hinge to a toilet bowl by a threaded shaft. The fastening assembly includes a fastening nut including a clamping portion having a resilient protrusion configured to allow axial movement of the fastening nut relative to the threaded shaft without rotation therebetween. The resilient protrusion has threads configured to engage the threaded shaft. The fastening nut includes a drive portion in which the clamping portion extends therefrom. The drive portion has a first segment coupled to a second segment by a shear segment. At least the first segment is configured to be engaged by a tool for the tool to rotate the fastening nut relative to the threaded shaft such that the shear segment fractures at a predetermined torque applied to the first segment relative to the second segment.

The disclosure discloses a toilet seat assembly installation structure convenient for disassembly and assembly, which comprises fixing members fixedly installed on a toilet seat; a hinge base including hinge portions and installation portions, the hinge portions hinging with a cover plate, the installation portions engaging with the fixing members; and snap-in connection members configured to detachably and position-limitedly installed on the installation portions along a vertical direction so that the snap-in connection members are fixedly engaged with the fixing members, or to detachably and position-limitedly installed on the fixing members along the vertical direction so that the snap-in connection members are fixedly engaged with the installation portions. The toilet seat assembly installation structure is easy to operate, can be dissembled and assembled by inserting/removing the hinge base into/from the fixing members, and is stable and reliable.

A method and apparatus for mounting a toilet seat hinge to a toilet pan uses an adhesive. The adhesivised surface of the hinge is held clear of the pan until correct positioning is established. Thereafter the adhesivised surface is displaced directly into contact with the pan.

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.

A raised toilet seat has a front part (2) and two wings (3, 4) of which the ends are, before the raised seat is fitted, separated by a gap. The wings (3, 4) at their free ends bear, in the case of one of them (3), a channel section equipped with notches (9, 10), and, in the case of the other (4), an opening (12) to accept the channel section, and ridges (13, 14, 15, 16) to retain the notches (9, 10).

A toilet seat support device that can be used as the basic chassis to construct a portable toilet, such as a composting toilet for camping use. The device is configured with suitable fixtures for other components, such as a toilet seat, a waste collection bucket, detachable legs, and other devices to be rapidly mounted onto the chassis, or disassembled for transport or storage.
