Toilet seat assembly having a lifting device and one way damping hinges

A suction cup assembly comprises of:

• a first suction cup, having a suction bell and a base,
• an elongated shaft, having a top and bottom ends wherein said bottom end of said shaft being fixedly connected to said base of said first suction cup,
• a release strip, having a first and second ends wherein said first end being connected to an exterior surface of said suction bell adjacent to a bottom planar surface of said suction bell, and
• an attaching means for attaching said suction cup assembly to a first planar surface of a first object;
• wherein:
• said first suction cup capable of being depressed to a vacuum state when said bottom planar surface of said suction bell of said first suction cup being pressed against a second planar surface of a second object;
• and
• said release strip capable of venting off said vacuum when said release strip being pulled by force.

A one-way damping hinge assembly comprises of

• a first sleeve fixedly connected to a rotator,
• a second sleeve fixedly connected to a stator,
• a third sleeve fit within said first sleeve, having a locking means for interlocking said first and third sleeves,
• a shaft fit within said second and third sleeves to form a rotational axis of said rotator, and at least
• a compressed elastic insert fit between interior and exterior circumferential surfaces of said second sleeve and shaft respectively, which generates a resistant torque during rotation of said shaft,
• wherein:
• said third sleeve having a ratchet means for performing a positive engagement between said third sleeve and said shaft when said rotator rotates in a first direction, so that said rotator, said third sleeve and said shaft rotate simultaneously under said resistant torque in said first direction;
• and
• said ratchet means performing no engagement between said third sleeve and said shaft when said rotator rotates in a second direction opposed to said first direction, so that said shaft remains stationary while rotator and said third sleeve rotate together freely without encountering said resistant torque in said second direction

A one-way damping hinge assembly comprises of:

• a first sleeve fixedly connected to a rotator,
• a second sleeve fixedly connected to a stator,
• a third sleeve fit within said second sleeve,
• a shaft fit within said first and third sleeves to form a rotational axis of said rotator, which has a locking means for interlocking said shaft and said first sleeve, and at least a compressed elastic insert fit between interior and exterior circumferential surfaces of said second and third sleeves respectively, which generates a resistant torque during rotation of said third sleeve,
• wherein:
• said third sleeve having a ratchet means for performing a positive engagement between said third sleeve and said shaft when said rotator rotates in a first direction, so that said rotator, said shaft and said third sleeve rotate simultaneously under said resistant torque in said first direction;
• and
• said ratchet means performing no engagement between said third sleeve and said shaft when said rotator rotates in a second direction opposed to said first direction, so that said third sleeve remains stationary while said rotator and said shaft rotate together freely without encountering said resistant torque in said second direction.
