Multi-tiered rotating shelf system

Abstract

A multi-tiered shelf system is provided. The multi-tiered shelf system includes a base, a lower shelf, an upper shelf and a mast. The base is configured to support the multi-tiered shelf system on a surface. The upper shelf is located a first distance from the surface. The mast extends between the lower shelf and the upper shelf. At least one of the upper and lower shelves is configured to be rotatable relative to the base and configured to separate into a plurality of shelf sections. At least one of the shelf sections is movable to a second distance from the surface.

1 . A multi-tiered shelf system comprising:
 a base configured to support the multi-tiered shelf system on a surface;   a lower shelf;   an upper shelf located a first distance from the surface; and   a mast extending between the lower shelf and the upper shelf;   at least one of the upper and lower shelves configured to be rotatable relative to the base and configured to separate into a plurality of shelf sections, at least one of the shelf sections movable to a second distance from the surface.   
   
   
       2 . The multi-tiered shelf system of  claim 1  wherein the upper shelf is separable into a plurality of shelf sections. 
   
   
       3 . The multi-tiered shelf system of  claim 2  wherein the upper tier is separable into two halves. 
   
   
       4 . The multi-tiered shelf system of  claim 1  wherein each of the shelf sections are independently rotatable and vertically adjustable. 
   
   
       5 . The multi-tiered shelf system of  claim 1  wherein both of the upper and lower shelves are independently rotatable with respect to the surface. 
   
   
       6 . The multi-tiered shelf system of  claim 1  wherein the relative positions of the upper and lower shelves are releasably secured with respect to one another. 
   
   
       7 . The multi-tiered shelf system of  claim 1  further comprising at least one cam lock to releasably secure at least one of the shelf sections. 
   
   
       8 . A multi-tiered shelf system comprising:
 a base configured to support the multi-tiered shelf system on a surface;   an upper shelf located a first distance from the surface and configured to be separable into a plurality of shelf sections; and   a mast extending between the base and the upper shelf, the plurality of shelf sections being operably coupled to the mast to permit at least one of the shelf sections to be vertically and rotationally adjustable about the mast relative to the other shelf sections without removing the at least one shelf section from the mast.   
   
   
       9 . The multi-tiered shelf system of  claim 8  wherein the upper tier is separable into two halves. 
   
   
       10 . The multi-tiered shelf system of  claim 8  wherein each of the shelf sections are independently rotatable and vertically adjustable. 
   
   
       11 . The multi-tiered shelf system of  claim 8  wherein the relative positions of the shelf sections are releasably secured with respect to one another. 
   
   
       12 . The multi-tiered shelf system of  claim 8  further comprising at least one cam lock to releasably secure at least one of the shelf sections. 
   
   
       13 . A multi-tiered shelf system comprising:
 a base configured to support the multi-tiered shelf system on a surface;   a mast having a fixed portion and a movable shaft portion, the movable shaft portion being releasably secured to the fixed portion;   a lower shelf operably coupled to the mast; and   an upper shelf operably coupled to the mast,   at least one of the upper and lower shelves configured to separate into a plurality of shelf sections such that at least one of the shelf sections is movable vertically and rotationally about the mast relative to the other shelf sections.   
   
   
       14 . The multi-tiered shelf system of  claim 13  wherein the upper shelf is separable into a plurality of shelf sections. 
   
   
       15 . The multi-tiered shelf system of  claim 14  wherein the upper shelf is separable into two halves. 
   
   
       16 . The multi-tiered shelf system of  claim 13  wherein each of the shelf sections are independently rotatable and vertically adjustable. 
   
   
       17 . The multi-tiered shelf system of  claim 13  wherein both of the upper and lower shelves are independently rotatable with respect to the surface. 
   
   
       18 . The multi-tiered shelf system of  claim 13  wherein the relative positions of the upper and lower shelves are releasably secured with respect to one another. 
   
   
       19 . The multi-tiered shelf system of  claim 13  further comprising at least one cam lock to releasably secure at least one of the shelf sections. 
   
   
       20 . The multi-tiered shelf system of  claim 13  wherein the movable shaft portion extends from within the fixed portion. 
   
   
       21 . The multi-tiered shelf system of  claim 20  further comprising at least one cam lock to releasably secure the movable shaft portion relative to the fixed portion.
