Abstract:
1. A toilet seat for detachably mounting on a toilet bowl having a toilet platform; comprising: a bowl seat having a seating portion and a mounting portion; and a seat hinge mechanism, comprising: two spaced apart retention bases adapted for securely mounting at said toilet platform of said toilet bowl; and two spaced apart joint members provided at said mounting portion of said bowl seat, wherein said joint members are detachably engaged with said retention bases respectively for detachably mounting bowl seat on said toilet platform of said toilet bowl in a tool-less manner, wherein each of said joint members comprises a pivot body pivotally mounting to said mounting portion of said bowl seat and base body which is integrally extended from said pivot body and is detachably coupled said respective retention base, such that when said base bodies are coupled with said retention bases respectively, said bowl seat is pivotally and selectively folded on top of said toilet platform of said toilet bowl, wherein each of said joint members further comprises a plurality of resilient arms spacedly extending to define a locking cavity therebetween and to detachably engage with said respective retention base such that each of resilient arms provides an urging force against said retention base when said joint member is mounted to said retention base to retain said bowl seat in position, wherein each of said retention bases comprises an elongated shaft body and an enlarged head body which is integrally and upwardly extended from said shaft body and is arranged in such a manner that when said joint member is coupled with said retention base, said head body is slidably passed through said locking cavity until said resilient arms are engaged with said shaft body to releasably lock up said joint member with said retention base, wherein each of said resilient arms has an enlarged engaging end defining an upper slanted guiding surface and a lower slanted guiding surface, wherein when each of said retention bases is engaged with said respective joint member, said head body of each of said retention bases is guided to slide at said lower slanted guiding surfaces to slightly and outwardly bend said resilient arms until said engaging ends of said resilient arms engage with said shaft body such that said head body is slid through said locking cavity, and when each of said retention bases is disengaged with said respective joint member, said head body is guided to slide at said upper guiding surfaces to slightly and outwardly bend said resilient arms to allow said head body of each of said retention bases being slid out of said locking cavity, wherein said base body comprises an outer surrounding wall and an inner wall defining an adjustment cavity therebetween, wherein said resilient arms are integrally formed at said inner wall that each of said resilient arms is adapted to slightly bend towards said adjustment cavity to adjust a size of said locking cavity so as to apply said urging force against said retention base, wherein each of said joint members further comprises a locking cap pivotally coupling with said base body to enclose said locking cavity and a locking wall which is integrally extended from said locking cap and is arranged in such a manner that when said locking cap is pivotally folded to enclose said locking cavity, said locking wall is slid into said adjustment cavity to restrict a movement of each of said resilient arms so as to prevent said retention bases from being disengaged with said joint members, wherein said locking further comprises a living hinge which extends into a integrally formed slot locating between said pivot body and said base body, said living hinge allows pivotal movements of said locking cap, wherein said bowl seat comprises a seat panel defining said seating portion thereon and a seat cover pivotally connecting to said seat panel via said seat hinge mechanism such that said seat panel and said seat cover are selectively and pivotally folded with respect to said toilet platform of said toilet bowl, wherein said seat hinge mechanism further comprises two panel joints spacedly and integrally extended from said seat panel and two cover joints spacedly and integrally extended from said seat cover to couple with said panel joints respectively, wherein said pivot body of each of said joint members is mounted between said panel joint and said cover joint via a pivot axle.
