Rotary shelf system

Abstract

A shelf system is shown and described. In one embodiment, the system is for use with a post having at least one aperture. The system comprises a first head and a second head configured to mount to the post. The system also includes a collar configured to encircle the post and rest on the first and second heads. The collar may engage a shelf or may be integral with a shelf. The collar has an inner track configured to contact the first head and an outer track configured to contact the second head. The collar is configured to allow the shelf to rotate around the post from a first rest-position and return to the first-rest position without encountering a second rest-position.

1 . A shelf system for use with a post having at least one aperture, said system comprising:
 a first head configured to mount to said post;   a second head configured to mount to said post; and   a collar configured to encircle said post and rest on said first head and said second head when said heads are mounted to said post, wherein said collar has an inner track configured to contact said first head and an outer track configured to contact said second head.   
   
   
       2 . The system of  claim 1 , wherein said first head is configured to be offset from said post a first distance, and wherein said second head is configured to be offset from said post a second distance that is greater than said first distance. 
   
   
       3 . The system of  claim 2 , wherein said first distance is selected to allow said first head to engagably support said inner track, and said second distance is selected to allow said second head to engagably support said outer track. 
   
   
       4 . The system of  claim 1 , wherein said inner track of said collar includes an inner indent, and wherein said outer track of said collar includes an outer indent. 
   
   
       5 . The system of  claim 4 , wherein said inner indent is shaped to engagably receive said first head, and wherein said outer indent is shaped to engagably receive said second head. 
   
   
       6 . The system of  claim 5 , wherein said inner indent and said outer indent are configured to create a single rest position for said collar, and wherein the remainder of said inner track and said outer track are substantially flat, thereby allowing said collar to rotate around said post 360 degrees and return to said single rest position without encountering a second rest-position. 
   
   
       7 . The system of  claim 4 , wherein said outer indent is substantially opposite said inner indent. 
   
   
       8 . The system of  claim 4 , wherein said inner indent has a first slope and said outer indent has a second slope, wherein said first slope and said second slope are configured to allow said inner indent to rest on said first head as said outer indent rests on said second head, thereby allowing for smooth and even force distribution as said collar rotates into and out of said rest position. 
   
   
       9 . The system of  claim 1 , wherein said first head, said second head, or both, include a curved portion. 
   
   
       10 . The system of  claim 1 , wherein said first head, said second head, or both, include rollers. 
   
   
       11 . The system of  claim 1 , wherein said first head and said second head are configured to mount to said post by connecting to each other. 
   
   
       12 . The system of  claim 11 , wherein said first head and said second head connect to each other by connecting said first head to one end of a pin and connecting said second head at the opposite end of said pin. 
   
   
       13 . The system of  claim 11 , wherein said first head and said second head connect to each other by having either said first head or said second head fixedly mounted to one end of a pin, and having the other head define an aperture sized to receive said pin, wherein said heads connect by positioning said pin within said aperture. 
   
   
       14 . The system of  claim 11 , wherein said first head is attached to a first pin, and wherein said second head is attached to a second pin, and wherein said first pin and said second pin connect within said post. 
   
   
       15 . The system of  claim 1 , wherein said first head and said second head are configured to mount to said post by threadably engaging said at least one aperture. 
   
   
       16 . The system of  claim 1 , further including at least one additional head configured to engage said collar. 
   
   
       17 . A shelf system for use with a post having at least one aperture, said system comprising:
 (a) a first head configured to mount to said post and be offset from said post a first distance;   (b) a second head configured to mount to said post and be offset from said post a second distance that is greater than said first distance; and   (c) a collar configured to encircle said post and rest on said first head and said second head when said heads are mounted to said post, wherein said collar has
 (i) a substantially circular inner track configured to rest on said first head, said inner track including an inner indent shaped to receive said first head, and 
 (ii) an outer track substantially coaxial with said inner track, said outer track configured to rest on said second head and including an outer indent shaped to receive said second head. 
   
   
   
       18 . The system of  claim 17 , wherein said inner indent is shaped and positioned to engagably receive said first head as said outer indent receives said second head, thereby establishing a first rest position and allowing said collar to rotate around said post 360 degrees and return to said single rest position without encountering a second rest-position. 
   
   
       19 . A rotary shelf system comprising:
 (a) a post;   (b) a first head mounted to said post and offset from said post a first distance;   (c) a second head mounted to said post and offset from said post a second distance greater than said first distance;   (d) a substantially circular shaped collar encircling said post, said collar having a top and a bottom,
 wherein said bottom of said collar defines an inner track and an outer track substantially coaxial with said inner track, and 
 wherein said inner track rests on said first head and said outer track rests on said second head; and 
   (e) a shelf connected to said collar.   
   
   
       20 . The system of  claim 19 , wherein said inner track includes an inner indent and said outer track includes an outer indent, wherein said inner indent and said outer indent are shaped and positioned to engagably receive said first head and said second head at substantially the same time, thereby establishing a first rest position and allowing said collar to rotate around said post 360 degrees and return to said single rest position without encountering a second rest-position.
