<p>A toilet seat control device (1) for automatically raising a toilet seat having a hinge assembly with a housing (2) for mounting on a toilet bowl (30) and a pivot shaft (3) for attachment to a toilet seat (31) rotatably mounted on the housing (2). A torsion spring (17) mounted between the pivot shaft (3) and housing (2) urges the seat (31) to a raised position. The seat (31) can be held in a lowered position adjacent the bowl (30) ready for use by a lock formed by a spring-loaded ball (9) which engages a complementary socket (8) in the pivot shaft (3). Preferably, release means for the lock incorporates a time delay device to automatically disengage the lock after a preset time. In this way the toilet seat (31) can be held down to facilitate use, but is always released for return to the raised position when not in use.</p> |
