Abstract
Abstract A kitchen cabinet is disclosed which includes a pivot support for supporting a plurality of kitchen cabinet shelves so that the shelves may pivot about a horizontal axis outwardly and downwardly toward the user to an access position for gaining access to the shelves. The shelves are returned to the storage position by pivoting the shelves back up into the storage position. A pivotable and foldable door having upper and lower panels is pivotably supported from the ceiling. The door is actuated by means of mechanical linkages interconnecting the shelving and the door. As the shelving is pivoted from the storage position into the access position, the door, which covers the front side of the shelving, is pivoted upwardly and away from the shelving to permit access thereto. The lower section of the door includes a linkage for folding the lower panel up toward the underside of the upper panel. A shelf stabilizing linkage is provided which maintains the shelving in the horizontal position while it pivots between the storage and access positions. The kitchen cabinet is readily hung from a vertical wall by means of a horizontal mounting bar affixed to the studs thereof. Hangers serve to hang the pivotable support for the shelving from the mounting bar. The pivotable support for the door structure is affixed to the ceiling.

Claim 1
Independent Claim
221 words
In a kitchen cabinet for supporting items and having a door structure for closing off access to the shelf structure: shelf means for providing a generally horizontal platform for supporting items to be stored thereon; shelf pivot means for connecting said shelf means to a support structure and for pivotably supporting said shelf means relative to the support structure and for pivoting of said shelf means outwardly and downwardly about a generally horizontal pivot axis of said shelf pivot means toward the user to a lower access position for permitting ready access thereto for the user; door means for movement relative to said shelf means for closing off access to said shelf means when said shelf means is in the elevated storage position and for opening thereof to permit access to said shelf means when said shelf means is pivoted into said lower access position; and door actuating means operatively associated with said shelf means and said door means for actuation of said door means in concert with pivoting movement of said shelf means between said storage and access positions for closing said door means over said shelf means when said shelf means is pivoted into said storage position and for opening said door means for access to said shelf means when said shelf means is pivoted into said access position.
Claim 2
Dependent Claim
221 words
In a kitchen cabinet for supporting items and having a door structure for closing off access to the shelf structure: shelf means for providing a generally horizontal platform for supporting items to be stored thereon; shelf pivot means for connecting said shelf means to a support structure and for pivotably supporting said shelf means relative to the support structure and for pivoting of said shelf means outwardly and downwardly about a generally horizontal pivot axis of said shelf pivot means toward the user to a lower access position for permitting ready access thereto for the user; door means for movement relative to said shelf means for closing off access to said shelf means when said shelf means is in the elevated storage position and for opening thereof to permit access to said shelf means when said shelf means is pivoted into said lower access position; and door actuating means operatively associated with said shelf means and said door means for actuation of said door means in concert with pivoting movement of said shelf means between said storage and access positions for closing said door means over said shelf means when said shelf means is pivoted into said storage position and for opening said door means for access to said shelf means when said shelf means is pivoted into said access position.
Claim 3
Dependent Claim
86 words
The apparatus of claim 1 wherein said door actuating means includes a door pivot means for pivoting said door means about a horizontal pivot axis and for pivoting said door means outwardly and upwardly about said door pivot axis into an access position for permitting access to said shelf means when said shelf means is pivoted into said access position and for pivoting said door means inwardly and downwardly for closing over said shelf means when said shelf means is pivoted upwardly into said storage position.
Claim 4
Dependent Claim
98 words
