Cabinet door mounting

Claim 2

In an appliance cabinet having a front access opening therein and a door pivotally mounted to said cabinet movable for closing and opening said access opening; a sector bracket secured to said door adjacent a vertical edge thereof and having a terminal end extending within said cabinet, a cam surface on the upper edge of said sector bracket adjacent said door, a plurality of door retaining detent recesses also in the upper surface of said sector bracket located progressively away from said door toward said terminal end, means pivotally mounted on the terminal end of said sector bracket providing an additional detent recess, said means pivoting into a position out of interfering engagement with the front surface of said cabinet when said door is moved to a closed position, stop means on said pivotally mounted means engaging said sector bracket when said pivotally mounted means is rotated forming a continuation of said sector bracket providing an additional detent recess, and a spring biased detent member mounted on the inner surface of said cabinet adjacent the access opening in alignment with said sector bracket continually engaging the upper surface thereof, said detent member engaging said recesses releasably holding said door in one of a plurality of open positions and engaging said cam surface continually urging the door toward the cabinet when the door is in its closed position, said detent member engaging said pivotal means and rotating the same during opening movement of said door to a downwardly extending position adjacent the front surface of said cabinet until said detent engages said additional recess retaining the door fully open.

Claim 3

In an appliance cabinet of the type having an access opening in the front vertical surface thereof and a door pivotally journalled at its lower edge relative to the front access opening; a pair of sector brackets secured to said door adjacent the opposite vertical edges thereof and each having a terminal end extending within said cabinet through vertically formed slots therein, a cam surface on the upper edge of said sector brackets adjacent said door, a first door retaining detent recess formed in the upper surface of each of said sector brackets, a second detent recess formed in each of said sector brackets inwardly of said first recess, means pivotally mounted on the terminal ends of said sector brackets providing a third detent recess and pivoting out of interfering engagement with the front vertical surface of said cabinet when said door is closed, stop means on said pivotally mounted means engaging said sector bracket when said pivotally mounted means is rotated forming a continuation of said sector bracket providing a third detent recess, and a spring biased detent assembly secured to the inner surface of said cabinet adjacent each side of the access opening whereby a detent member is continuously biased into sliding engagement with the upper surface of each of said sector brackets, said detents engaging said first recesses to retain said door in a partially opening position whereby said door forms a sliding surface for conveying articles into the cabinet through said access opening, said detents engaging said second recesses releasably retaining said door in a further open position whereby said door forms a shelf for the placement of articles thereon prior to insertion within the cabinet and while removing articles therefrom, said detents engaging said pivotal means and rotating the same during opening movement of said door to a third downwardly extending position adjacent the front vertical surface of said cabinet until said detents engage the third recess in said pivotal means thereby retaining the door fully open, said detents engaging said cam surfaces to urge said door toward said cabinet when said door is moved to a fully closed position.

Claim 4

In an appliance cabinet of the type having an access opening in the front vertical surface thereof and a door pivotally journalled at its lower edge relative to the front access opening; a pair of sector brackets secured to said door adjacent the opposite vertical edges thereof and each having a terminal end extending within said cabinet through vertically formed slots therein, a cam surface on the upper edge of said sector brackets adjacent said door, a first door retaining detent recess formed in the upper surface of each of said sector brackets, a second detent recess formed in each of said sector brackets inwardly of said first recess, means pivotally mounted on the terminal ends of said sector brackets providing a third detent recess and pivoting out of interfering engagement with the front vertical surface of said cabinet when said door is closed, stop means on said pivotally mounted means engaging said sector bracket when said pivotally mounted means is rotated forming a continuation of said sector bracket providing a third detent recess, and a spring biased detent assembly secured to the inner surface of said cabinet adjacent each side of the access opening whereby a detent member is continuously biased into sliding engagement with the upper surface of each of said sector brackets, said detents engaging said first recesses to retain said door in a partially opening position whereby said door forms a sliding surface for conveying articles into the cabinet through said access opening, said detents engaging said second recesses releasably retaining said door in a further open position whereby said door forms a shelf for the placement of articles thereon prior to insertion within the cabinet and while removing articles therefrom, said detents engaging said pivotal means and rotating the same during opening movement of said door to a third downwardly extending position adjacent the front vertical surface of said cabinet until said detents engage the third recess in said pivotal means thereby retaining the door fully open, said detents engaging said cam surfaces to urge said door toward said cabinet when said door is moved to a fully closed position.
