Patent ID: 7377500

Claim:
A combination comprising: at least one shock absorbing device, a moving body, and a movement restricting part, wherein said at least at least one shock absorbing device comprises a cylinder enclosing a viscous fluid, a piston rod, a piston slidably situated in the cylinder to divide an interior of the cylinder in two axially separated parts and connected to the piston rod, said piston including an orifice communicating the two parts, an inner member integrally connected with the piston rod, and an outer member disposed about an outer perimeter of the inner member to be axially movable with respect to the inner member, said inner and outer members being arranged to define a gap therebetween through which the viscous fluid can flow so that the gap is reduced as an amount that the inner member protrudes into the outer member increases to thereby form a variable orifice, and a spring disposed between the inner and outer members to urge the inner and outer members away from each other, said movement restricting part restricts movement of the moving body by contacting with the moving body, one of the cylinder and the piston rod being fixed to the moving body such that the other of the cylinder and the piston rod slightly projects outwardly from the moving body, said moving body is at least one of a toilet cover and a toilet seat, and said movement restricting part is at least one of a toilet main body and the toilet seat contacting the toilet cover, and a plurality of said shock absorbing devices is arranged to be spaced apart from each other, and is attached to said at least one of the toilet cover and the toilet seat as the moving body without connecting to the movement restricting part to absorb shocks by rotational movements of the toilet cover and the toilet seat against the movement restricting part.
