Definitions

  • the invention relates to an appliance having shelving.
  • the invention may include appliances in which the shelving is moveable.
  • a recent United Nations Population Division report identified that globally the number of older persons (60 years or older) will more than triple by 2050. Because the current target market does not address the growing global aging community, it does not address those most likely to be impaired in movements of daily living, like reaching into the refrigerator for something cold to drink.
  • a recent American with Disabilities report stated that in the population 15 years old and older, 2.2 million people used a wheelchair. Another 6.4 million used some sort of ambulatory aid such as a cane, crutches, or walker. It also identified that 18 million individuals have difficulty grasping a small object. Whether these people are single homeowners or living with someone else, these statistics point to a need to address universal design in both lifting and moving on a daily basis within private homes.
  • the target market also misses those who need appliances for campers, recreational vehicles, boat, ship, dorm, "state-subsidized,” military, assisted living, multiunit and other limited space users, for example.
  • the increasingly available partially prepared items to "speed cook” have also impacted appliance storage and use. With the increasing use of the microwave, the axis of the "kitchen triangle” has shifted to include that appliance also. Decreasing the space between the swinging door shelves and the body of the appliance storage would assist in maximizing spatial use of smaller kitchen appliances.
  • an appliance having shelving in which the outer door is disconnectably connected to the inner shelving.
