Drawer storage with magnetic connectors

Abstract

A tray unit includes a main body including at least one storage space and a wall structure surrounding the at least one storage space. The wall structure includes a bottom wall and a sidewall surrounding the bottom wall to define the at least one storage space. The tray unit further includes a magnet arranged with the wall structure at a location along a perimeter of the main body.

1 . A tray unit comprising:
 a main body that includes at least one storage space and a wall structure surrounding the at least one storage space, the wall structure comprising a bottom wall and a sidewall surrounding the bottom wall to define the at least one storage space; and   a magnet arranged with the wall structure at a location along a perimeter of the main body.   
     
     
         2 . The tray unit of  claim 1 , further comprising a plurality of storage spaces separated from each other by the wall structure. 
     
     
         3 . The tray unit of  claim 1 , wherein the magnet comprises:
 a first magnet arranged with a first side of the main body; and   a second magnet arranged with a second side of the main body opposite to the first side.   
     
     
         4 . The tray unit of  claim 1 , wherein the magnet comprises a first surface having a first polarity and a second surface having a second polarity. 
     
     
         5 . The tray unit of  claim 1 , wherein the magnet is removable and reinsertable to allow one of the first and second surfaces thereof to face outwardly from the perimeter of the main body. 
     
     
         6 . The tray unit of  claim 1 , wherein the wall structure comprises a recess configured to receive and hold the magnet at the location along the perimeter of the main body. 
     
     
         7 . The tray unit of  claim 6 , wherein the recess is configured to receive and hold the magnet so that the magnet does not protrude outwardly from the perimeter of the main body. 
     
     
         8 . The tray unit of  claim 6 , further comprising a magnet cover configured to cover the magnet. 
     
     
         9 . The tray unit of  claim 8 , wherein the magnet cover comprises a marking for indicating a polarity. 
     
     
         10 . The tray unit of  claim 8 , wherein the magnet cover comprises a magnet cap. 
     
     
         11 . The tray unit of  claim 10 , wherein the main body further includes a strip formed around the perimeter thereof and comprising an opening exposing the recess,
 wherein the magnet cap is inserted into the opening of the strip to cover the magnet.   
     
     
         12 . The tray unit of  claim 8 , wherein the magnet cover comprises a strip formed around the perimeter of the main body to cover the magnet. 
     
     
         13 . The tray unit of  claim 12 , wherein the strip comprises a covering portion located correspondingly to the magnet. 
     
     
         14 . The tray unit of  claim 13 , wherein the strip is removable. 
     
     
         15 . The tray unit of  claim 1 , further comprising a protective cover configured to cover an upper surface of the bottom wall. 
     
     
         16 . The tray unit of  claim 15 , wherein the protective cover comprises a protrusion formed on a bottom surface thereof to engage a recess formed correspondingly thereto on an upper surface of the bottom wall. 
     
     
         17 . A drawer storage assembly comprising the tray unit of  claim 1 . 
     
     
         18 . The drawer storage assembly of  claim 17 , wherein the tray unit is a first tray unit, and the drawer storage assembly further comprises a second tray unit magnetically attached to the first tray unit. 
     
     
         19 . The drawer storage assembly of  claim 18 , wherein the second tray unit comprises:
 a main body that includes at least one storage space and a wall structure surrounding the at least one storage space, the wall structure of the second tray unit comprising a bottom wall and a sidewall surrounding the bottom wall to define the at least one storage space; and   a magnet arranged with the wall structure of the second tray unit at a location along a perimeter of the main body of the second tray unit.   
     
     
         20 . The drawer storage assembly of  claim 19 , wherein a number of the storage spaces of the first tray unit is different from that of the second tray unit.
