Roll-out shelving system

Abstract

This disclosure provides a shelving system comprising a first shelf member fixedly on shelf support members and a second shelf member positioned above the first shelf member and movably mounted on the shelf support members. Further, sliding means are provided for horizontally moving the second shelf member on a top surface of the shelf support members such that the second shelf member moves out of a vertically stacked alignment with respect to the first shelf member. Also, locking means are provided for detachably locking the second shelf member with the first shelf member after a predefined amount of the horizontal movement permitted to the second shelf member

The following is claimed: 
     
         1 . A shelving system comprising:
 a first shelf member fixedly on shelf support members;   a second shelf member positioned above the first shelf member and movably mounted on the shelf support members,   sliding means for horizontally moving the second shelf member on a top surface of the shelf support members such that the second shelf member moves out of a vertically stacked alignment with respect to the first shelf member; and   locking means for detachably locking the second shelf member with the first shelf member after a predefined amount of the horizontal movement permitted to the second shelf member.   
     
     
         2 . The shelving system of  claim 1 , wherein the first shelf member and the second shelf member are selected from the group consisting of shelving members, hanging rods, drawers, bins, and combinations thereof. 
     
     
         3 . The shelving system of  claim 1 , wherein the sliding means are selected from a group of tracks, pulleys, rollers, and combinations thereof. 
     
     
         4 . The shelving system of  claim 1 , wherein the locking means are selected from a group of hook type locking member, spring-biased locking members, and combinations thereof. 
     
     
         5 . The shelving system of  claim 1 , wherein the locking means include a series of locking slots disposed at various points along the side edges of the first shelf member to allow for customization of a shelf size of the second shelf member. 
     
     
         6 . The shelving system of  claim 1 , wherein the second shelf member is adapted to horizontally move from a retracted position to an extended position. 
     
     
         7 . The shelving system of  claim 6 , wherein the second shelf member includes a back cover which slides or arrives over the first shelf members to complete a shelf surface during the extended position of the second shelf member. 
     
     
         8 . The shelving system of  claim 6 , wherein the second shelf member includes spring members, and wherein when the locking means are disengaged, the spring members automatically return at their initial rest position under the bias of internal spring structures associated with spring members, so as to return the second shelf members to the retracted position. 
     
     
         9 . The shelving system of  claim 1 , wherein each of the shelf support members includes a support arm and a mounting hook, and wherein the support arm provides support for mounting of the first shelf member and the second shelf member, and the mounting hook mounts the shelf support members on mounting slots of a mounting frame. 
     
     
         10 . The shelving system of  claim 9 , wherein the sliding means are mounted on the top surface of the support arms of the shelf support members. 
     
     
         11 . The shelving system of  claim 10 , wherein the sliding means are connected to the support arms by a connecting structure. 
     
     
         12 . The shelving system of  claim 11 , wherein the connecting structure is a channel extending from the shelf support members to the sliding means. 
     
     
         13 . The shelving system of  claim 11 , wherein the connecting structure defines a substantially U-shaped or i-shaped configuration.
