  • Patent number: 5161263
    Abstract: An articulable training toilet apparatus for use in cooperation with a supporting toilet seat of a conventional toilet, and which can alternatively be used as a stand alone toilet on independent ground and table surfaces. A seat having an outer peripheral edge and an inner peripheral edge which defines a waste passage aperture, is operably attached to one or more leg members. The leg members are positionable between a fully deployed position, which serve to elevate the seat above a surface so as to enable usage of the appratus as a stand alone toilet, and a fully retracted position which enables the apparatus to be used in operable cooperation with a supporting toilet seat of a conventional toilet. Restraining members are attached to the leg members so as to facilitate aligned and secured cooperation with the conventional supporting toilet seat, when the apparatus is used in association therewith.

  • Patent number: 4556253
    Abstract: Lightweight chair from a single unitary die-cut and scored generally rectangular blank of sheet material which is collapsible for easy storing and carrying, and which pops open for easy set-up. The lower 10-20% of the blank has a plurality of flaps gulable to the inner face of adjoining sidewall panels to form a reinforced base perimeter. Half of the blank forms the chair base sidewalls, and the remaining upper half forms a pair of adjoining seat/back panels which are delineated from the sidewalls by a set of generally W-shaped score lines. An assembly tab at one end is fastened to the opposite side of the other end of the blank to form in cross-section an enclosed polygon, preferably a modified hexagon of unequal sides. A first of the pair of seat/back panel assemblies is folded down with one or more tabs or flaps frictionally engaging one or more of the sidewall panels.
