Description
BACKGROUND OF THE INVENTION

The present invention relates to accessing kitchen storage, and in particular to a stool to access top shelves of kitchen pantry cupboards, and the like.


The top shelves of kitchen pantry cupboards are the most under-utilized and neglected space in households the world over. Solutions like swiveling shelves; fixed or collapsible step stools; grabbing tools/tongs and even ladders leave much to be desired based on quick accessibility, storage and cost.


BRIEF SUMMARY OF THE INVENTION

The present invention addresses the above and other needs by providing a folding kitchen stool making use of an unrecognized and unused space between the inner surface of a ground level kitchen pantry cupboard door and the cupboard. The folding kitchen stool may be stored in a pocket on the inner surface of the door, or hung behind the cupboard door using a docking bracket in the unused space out of sight, but available when needed and rapidly unfolded. After use, the folding kitchen stool may be returned to the pocket or folded and again hung from the door. The docking bracket may be placed over the top edge of other doors and the folding kitchen stool is hooked on to it until needed anywhere in the house.


In accordance with another aspect of the invention, there is provided a folding stool which is stored in a pocket on an inner surface of a cupboard door. The stool includes left and right folding legs. The right folding legs are widely spaced apart leaving a gap for the left folding legs to overlap the right folding legs when the stool is folded for storing. The pocket provides a mouth which accepts the left folding legs to store the folded stool.


In accordance with another aspect of the invention, there is provided a folding stool stored in a pocket behind a cupboard door of a floor level cupboard, out of sight, but immediately available and easily expanded for use. The stool does not add any strain on hinges of the cupboard door, and can be lifted off the pocket to be used anywhere else or even re-inserted in to another pocket installed on a different cupboard door.


In accordance with another aspect of the invention, there is provided a folding stool which is supported by four folding legs. Being foldable, it is convenient to install complete units under each difficult-to-reach shelf.


In accordance with another aspect of the invention, there is provided a method for storing a folding stool. The method includes: placing a docking bracket on the upper edge of a chosen door, lifting a rear strut up; pushing the rear legs forwards and upwards to rest against the bottom of the top; and folding the front legs down and backwards over the rear legs; lifting the folded stool up by the brace of the two rear legs and hooking on to the docking bracket.


In accordance with still another aspect of the invention, there is provided a method for deploying a folding stool. The method includes: folding the rear legs away from the top; making sure that the rear strut is pushed and locked down below the horizontal level to achieve stability; folding the front legs away from the top; and making the front strut meet the rear strut to provide stability.
