WIPO Patent Application WO/2003/101269
Kind Code:
A1
Abstract:
An opening/closing device (31) for a toilet seat or toilet lid has a swing shaft (17) provided on a swing center line (C) of a toilet seat (3) or toilet lid (4) that swings around base end portions (3 , 4 ), respectively, and rises. The device comprises an opening/closing unit (5) indirectly fixed to a toilet bowl main body (30); an output shaft (12) that is provided on the swing center line (C), one end portion of which shaft being removably connected to the swing shaft (17) of the opening/closing control unit (5) and the other end portion being detachably connected to the base end portion (3 ) of the toilet seat (3); and a toilet seat transmission unit (9) containing a twist spring (13) that urges the output shaft (12) in an opening direction of the toilet seat (3). The opening/closing device (31) for the toilet seat or toilet lid is relatively small in size and able to stably hold the toilet seat or toilet lid in a raised position. Commonality of structural parts can be achieved depending on the magnitude of torque caused by the own weight of the toilet seat or toilet lid.
