Abstract:
1. A spring-loaded shelf for an existing cooler used for storing a plurality of items, for selectively raising said items as the cooler becomes emptied of the items, so that a user may retrieve one of said items without reaching deeply within the confines of the cooler, said spring-loaded shelf comprising: a base having a first lateral side, a second lateral side, a third side, and a fourth side; a platform which overlays the base, said platform having a first lateral side, a second lateral side, a third lateral side, and a fourth side, said platform for supporting said items; two scissor-type linkages which pivotally attach the platform to the base, each scissor-type linkage comprising a first arm and a second arm, each having a top, a bottom, and a center, wherein the top of each arm is slidably mounted to the platform, the bottom of each arm is slidably mounted to the base, and the center of the first arm is pivotally attached to the center of the second arm at a hinged junction; and a lifting mechanism having two spring assemblies and two tracks for automatically raising the platform with respect to the base upon the scissor-type linkages as said items are selectively removed therefrom, thereby obviating the need for a user to reach deeply within the confines of the cooler in order to retrieve one of said items.
