20110214942 | Assist Lift - The lift assembly eliminates the need for unsightly items such as step ladders, stools etc. in the personal kitchen area. It provides safe, easy access to upper areas that are difficult to reach. The lift assembly has a step that extends automatically by a convenient and simple toe tap to the cabinet kick panel located at the bottom of all standard kitchen cabinets. Upon extension, the step raises to a height of up to ten inches. Once a person has stepped off the step a load sensor first triggers the automatic lowering of the step and then urges the front movable section of the telescoping frame to retract back under the cabinet where it is out of sight and ready for use again. No unsightly ladders, no tripping over step stools. | 09-08-2011 |
