  • Toilet attachment with easily detachable seat
    Patent number: 5666672
    Abstract: A toilet accessory (10) having readily detachable toilet seat (14) and toilet lid (16). A hinge shaft (74) is supported by a pair of posts (72) to protrude away from the housing (12). The hinge portions of the toilet seat and the toilet lid are provided with elastic collars (84) of C-shaped cross-section and are snap-fitted on the hinge shaft (74). When the toilet seat and the toilet lid are to be removed for washing or cleaning, they can be readily dismounted only by pulling with hands. To re-install, the hinge portions readily snap-fit on the hinge shaft by bringing the elastic collars (84) in contact with the hinge shaft (74) and by pressing down the hinge portions. Since the hinge shaft (74) and the posts (72) are exposed out of the housing (12), they can be easily accessed for cleaning.
