Motorized Upper and Lower Storage Shelves

Abstract

A storage VBS with opposing side walls, a top, a bottom, a back with an open or openable front, houses moveable upper and lower adjustable shelving boxes. The shelving boxes are moveably motorized and controlled sequentially. An upper shelf is made accessible by driving an upper shelving box out of the VBS and then adjusting the shelf height for storage or retrieval of an item. The upper shelving box must be returned to the VBS prior to operating the lower shelving

What is claimed is: 
     
         1 . A lower vertical box system comprising:
 a vertical box structure;   a motorized platform;
 said motorized platforms horizontally moves a shelving box from inside of said vertical box structure to an outside extended position; 
 said shelving box is positioned with an open front and at least one shelf; 
 said shelving box is vertically adjusted while in said outside position; 
 said adjusted means is controlled with a push button 
   
     
     
         2 . The lower box system of  claim 1  wherein said shelving box is moveably attached to said motorized platform. 
     
     
         3 . The lower box system of  claim 1  wherein said shelving box is guided vertically with a pair of roller bearings sited in vertical channels mounted on opposing sides of said boxed shelving wherein said roller bearing is mounted to a first end of a pivot member and the other end is pivotally mounted to said motorized platform. 
     
     
         4 . The lower box system of  claim 1  wherein vertical movement of said shelving box is driven by a linear actuator located vertically at an outer back side of said shelving box wherein a stationary end of said linear actuator is mounted to said motorized platform, a moveable ram end of said linear actuator is connected to a horizontal bar member, said horizontal bar member having pulleys mounted at each end, said pulleys support coated stainless steel cables used as lifting connectors having one end connected to the top surface of said motorized platform, said other end connected to a bottom back side of said shelving box forming a cable pulley system for raising and lowering said shelving box, said cable pulley system raises and lowers said shelving box at a 2 to 1 ratio compared to stroke of said linear motor. 
     
     
         5 . The lower box system of  claim 1  wherein sequences for activating said motorized platform and shelving box are controlled with switch means comprises a first switch for selectively connecting said linear actuator to a source of electrical energy. 
     
     
         6 . The lower box system of  claim 1  wherein materials to build said lower box system can be from the group consisting of wood, metals or plastic depending on a type of application, whether for kitchen use, to store and retrieve food items, garage use, or manufacturing assembly.
