Two polymeric, cylindrical, and tubular bushings that each have an inner surface defining inner diameter, an outer surface defining an outer diameter, an upper end, a lower end opposing the upper end of the bushing, a bushing length separating the upper and lower ends of the bushing, and a bushing channel defined by the inner surface of the bushing and spanning the bushing length, disposed, respectively, within bowl bores defined by a toilet bowl, and with a threaded screw, coupled to a toilet seat, disposed within the bushing channel and coupled to the inner surface of the bushing, wherein the bushings prevent inadvertent loosening of the toilet seat when attached to the toilet bowl.

This application discloses a cover device, a toilet cover assembly and a toilet, the cover device including a cover (2), at least one shaft sleeve (2-1, 2-2) provided on one end of the cover (2), the cover device further including at least one helical spring (5-1, 5-2) and at least one damper (4-1, 4-2); an outer end of the at least one helical spring (5-1, 5-2) is fixedly connected to the at least one shaft sleeve, such that the cover (2) applies a compression force to the at least one helical spring (5-1, 5-2) when rotating downward; and a bearing of the at least one damper (4-1, 4-2) penetrates through the center of the at least one helical spring (5-1, 5-2) and is fixedly connected to an inner end of the helical spring (5-1, 5-2), and an outer cylinder part of the at least one damper (4-1, 4-2) is fixedly connected to the at least one shaft sleeve (2-1, 2-2), such that the at least one damper (4-1, 4-2) resists against elastic force release of the at least one helical spring (5-1, 5-2), wherein the rated elastic force of the at least one helical spring (5-1, 5-2) is larger than the gravity of the cover (2). This invention makes the cover rise up automatically and slowly without use of electricity, which not only is simple in structure, but also is safe and saves energy.

A toilet cover base includes a base body; a base side plate connected to a side of the base body; a pipeline arrangement groove disposed in the base body and configured to accommodate at least one pipeline; a pipeline through groove disposed in the base side plate and configured to allow the at least one pipeline to pass through; and a trim cover removably installed in the pipeline through groove.

A fastening system for a toilet seat and/or cover includes a bolt, a nut, a hinge, and a retainer. The nut is coupled to the bolt and includes a locking member defining a plurality of teeth. The hinge is disposed between a head of the bolt and the nut. The retainer is configured to engage with the locking member and the hinge. The fastening system is configured to detachably couple a toilet seat to a toilet body. The fastening system is configured to be installed onto the toilet body from a single side of the toilet body.

A toilet flange and method for installing a toilet is disclosed. The toilet flange assembly comprises a toilet flange portion and a support portion. The toilet flange and support are adapted to be permanently connected to each other using a self-locking mechanism. The support comprises a rectangular or square support base and an inner cavity with two studs or bolts to attach the support to the toilet. The toilet flange may further comprise a cylindrical section, an upper rim section and a cap to prevent the falling of debris into the waste water pipe. The cap can be easily broken up and removed before installing the toilet. The toilet flange may be used in either new or existing toilet installations to allow better toilet stabilization and easy installation of floor tiles.
