Abstract:
A powered auxiliary toilet seat lift that fits about the sides and front of a toilet stool having an upper orifice for vertical motion of an auxiliary toilet seat to aid ingress and egress of disabled and infirm persons on the auxiliary toilet seat for use of the toilet stool, comprising in combination:a U-shaped casement having similar side elements interconnected by a forward end plate to extending rearwardly the forward end plate to define a medial void to fit about the vertical surface of the toilet stool, said casement having coplanar vertical height substantially the same as the height of the toilet stool and the side elements being peripherally defined to enclose similar internal side chambers; a laterally opposed first pair of compound jackscrews pivotally carried in the rearward portion of the internal side chamber of each side element and a laterally opposed second pair of compound jackscrews carried in the forward portion of the internal side chamber of each side element, all said jack screws being extendable spacedly above the upper portion of the casement; powering mechanism associated with each jackscrew carried in the internal side chambers of the side elements, each said powering mechanism including an electrically powered motor driving the associated jackscrew through a transmission for rotary motion of the jackscrew to move the upper portion of each jackscrew vertically; toilet seat structure having a rigid planar base substantially co-extensive with the upper portion of the casement, said base pivotally supported on the upper portions of the laterally opposed pairs of jackscrews for limited vertical motion above the casement responsive to jackscrew motion, defining a medial orifice, geometrically, similar to the shape of the upper orifice of the toilet stool and defined vertically above the upper orifice of the toilet stool when the casement is positioned about sides and front of the toilet stool, and an auxiliary toilet seat pivotally carried for motion in a vertical plane to rest on the upper surface of the base and be pivoted in an upward and rearward direction therefrom; control apparatus to determine vertical and tilting motion of the toilet seat structure relative to the casement having at least one controller with at least two switches to start and stop jackscrew motion to determine up and down vertical motion of the toilet seat structure between a lower use position immediately above the upper portion of the casement and an upper entry and exit position spacedly above the casement.
