Abstract
A freezer tip out bin includes a stationary portion, a rotating portion pivotally coupled to the stationary portion, and a biased actuator coupled to the rotating portion.
Description




BACKGROUND OF THE INVENTION




This invention relates generally to tip out bins, and, more specifically, to a tip out bin for a freezer.




Known refrigerators include a cabinet housing including an outer case and one or more inner liners therein that defines a fresh food compartment and a freezer compartment. The fresh food compartment and freezer compartments are closed by separate access doors hingedly attached to the case. A number of storage shelves, baskets, and drawers are employed in the fresh food compartment to organize food. See, for example, U.S. Pat. No. 5,729,997. One such food storage feature is commonly known as a freezer tip out bin that is intended to store frozen foods therein. Conventional freezer tip out bins are, however, disadvantaged in several respects.




For example, some tip out bins are relatively difficult to tip out. Further, due to efforts to facilitate tipping out a bin, some tip out bins tip out too easily causing freezer owners to constantly close an accidentally tipped out bin.




BRIEF DESCRIPTION OF THE INVENTION




In one aspect, a freezer tip out bin is provided. The freezer tip out bin includes a stationary portion, a rotating portion pivotally coupled to the stationary portion, and a biased actuator coupled to the rotating portion.




In another aspect, a freezer tip out bin includes a stationary portion including an opening positioned in a raised portion of the stationary portion, the raised portion having a substantially elongated oval shape and a substantially arcuate cross-section. The freezer tip out bin also includes a rotating portion pivotally coupled to the stationary portion; the rotating portion includes at least one sidewall including a cavity unitary with a side wall support member extending out from an inner wall of the sidewall and down from an upper surface of the sidewall. The freezer tip out also includes a biased actuator coupled to the sidewall and positioned in the cavity, and the opening is sized to receive the biased actuator.




In still another aspect, a refrigerator is provided. The refrigerator includes a fresh food portion, a freezer portion proximate the fresh food portion, a door pivotally mounted to the freezer portion, and a tip out bin mounted to the door. The tip out bin includes a stationary portion, a rotating portion pivotally coupled to the stationary portion, and biased actuator coupled to the rotating portion.

108


,


110


may be formed by bending and welding a sheet of a suitable metal, such as steel. The illustrative embodiment includes two separate liners


108


,


110


as it is a relatively large capacity unit and separate liners add strength and are easier to maintain within manufacturing tolerances. In smaller refrigerators, a single liner is formed and a mullion spans between opposite sides of the liner to divide it into a freezer compartment and a fresh food compartment.




A breaker strip


112


extends between a case front flange and outer front edges of liners


108


,


110


. Breaker strip

The insulation in the space between liners


108


,


110


is covered by another strip of suitable resilient material, which also commonly is referred to as a mullion


114


. Mullion


114


also preferably is formed of an extruded ABS material. Breaker strip


112


and mullion


114


form a front face, and extend completely around inner peripheral edges of case


106


and vertically between liners


108


,


110


. Mullion


114


, insulation between compartments, and a spaced wall of liners separating compartments, sometimes are collectively referred to herein as a center mullion wall


116


.




Shelves


118


and slide-out storage drawers


120


, sometimes referred to as storage pans, normally are provided in fresh food compartment


102


to support items being stored therein. A bottom drawer or pan


122


is commonly referred to as a crisper drawer and is intended for storage of fruit and vegetables. It is understood, however, that the present invention may be employed in any of storage pans


120


in addition to, or in lieu of, pan


122


.




Refrigerator


100
