  • Patent number: 6012180
    Abstract: A pair of compound leaf springs are formed to hold a commode seat in the up position. The leaf springs have a primary curve for spring lifting power, a second curve to reduce friction between the seat and spring when the seat is lowered, and a third curve to act as a spring washer to hold the leaf spring in place between the seat and commode. By holding the seat in the up position unless a user wishes to lower it, the seat is less apt to be soiled when the commode is used for urination.
