Abstract
Abstract A horizontal seat member defining a central vertical opening therethrough is provided for stationary support from the open upper end of a toilet bowl. The seat member includes front, rear and opposite side portions and defines an upper seat surface which is upwardly concave in a front-to-rear extending direction for more readily conforming to the lower torso configuration of a person having his or her legs bent sharply in positions similar to those assumed when the person is in a squatting position. The forward extremity of the seat member includes a depending portion terminating downwardly in a forwardly and horizontally directed footrest portion for support of the user's feet and the seat member has a hinged cover operatively associated therewith, the cover including first and second sections thereof pivotally joined together along adjacent marginal portions and being swingable between a raised upstanding open position with the cover sections substantially coplanar and a lowered horizontal position with the cover sections relatively oppositely inclined downwardly toward the adjacent marginal edges thereof to more closely conform to the concave seat member. The cover includes structure thereon for releasably retaining the cover sections in the coplanar position thereof.
