Abstract:
A storage carousel is disclosed which includes multiple vertically displaced carousel frames ( 1 ) independently rotatable on a common axis ( 6 ). Each of the carousel frames has ridges ( 5 ) for removable mounting a plurality of storage bins ( 9, 10, 11  and  12 ) in side-by-side relationship for access by a user.

Description:
FIELD OF THE INVENTION 
     This invention relates to storage apparatus. More particularly although not exclusively it discloses an improved space efficient stand for storage bins. 
     BACKGROUND TO THE INVENTION 
     Existing storage bins, such as for example “Dexion” type bins, are normally mounted on racks against a wall or other fixed surface. Such arrangement is not spatially efficient as access room has to be maintained around all sides of the rack to reach each bin. Also persons wishing to access the contents of various bins have to continually move across the fixed rows of racks. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of this invention to ameliorate the aforementioned disadvantages and accordingly a storage apparatus is disclosed which includes multiple vertically displaced carousels independently rotatable on a common axis, each of said carousels having means for removably mounting a plurality of storage bins in side-by-side relationship for access by a user. 
     Preferably said means for mounting said storage bins comprises a ridge or upstanding edge of a carousel frame which engages in slots on said bins. 
     It is further preferred that said carousel frame is rectangular with a central hub to receive said axis. 
     It is further preferred that said bins are arranged adjacently along sides of said carousel frames. 
     It is further preferred that said carousel frame includes turning handles extending out from the corners of said frame. 
     It is further preferred that said carousels are adapted to mount a range of sizes of said bins.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring first to  FIG. 1  the carousel frame may comprise a rectangular sheet metal box-like structure  1  with a central hub  2  and arms  3  with handles  4  extending out from the corners. The edges of the frame are defined by upstanding ridges  5  along each side. As described later the size of the ridges  5  may vary in height in accordance with the storage bins to be fitted. 
     In use the carousel frame  1  is rotatably mounted on a base comprising an upright axis  6  and horizontal stabilising arms  7  as shown in  FIG. 2 . The hub  2  is fitted over the axis  6  with the two components being sized so that the carousel frame is held in a horizontal configuration but is still able to rotate freely about said axis on rollers  8 . With the addition of suitable low friction spacer rings or bearings  8 A between them a series of independently rotatable carousel frames  8 B can thus be mounted, one above the other, on the axis  6  as shown in  FIG. 3 . These carousel frames preferably decrease in size from the bottom to the top of the axis. 
     As best shown in  FIGS. 3 and 4  the frame with the highest ridge  5  is, with this embodiment, located at the bottom where it mounts the largest bins  9  around the periphery. Successively higher carousels may be reduced in size and adapted to mount smaller bins  10 ,  11  and  12 . 
     The currently preferred form of bin is best shown schematically in  FIG. 4  from the front and in  FIG. 5  from the rear. It may comprise an open top  13  which slopes down to a low front panel  14  to thereby form a storage container for small items which is easily accessed by a user. The bin is also formed with downwardly extending tongue  15  across the upper back panel. This tongue forms a slot  16  which engages the aforementioned side ridges of the carousel frames so that a series of bins can be mounted side-by-side as shown in  FIG. 4 . With this embodiment the largest bins are located on the lowermost frame. They decrease progressively in size toward the top. Each carousel frame is also independently rotatable using the aforementioned handles  4 . This reduces space requirements and enables a user to easily access all bins from the one location. 
     With the second embodiment of the invention shown in  FIGS. 6 and 7  the main components which correspond in function to those of the first embodiment are identified by the same numbers which however are primed (′) to distinguish them. There is an upright rectangular sheet metal frame  17  with horizontal spaced apart support members  18 . A vertical axis  6 ′ extends the height of the frame  17  and passes through each of the horizontal support members. With the addition of suitable bearings (not shown) a series of independently rotatable carousel frames  8 B′ are mounted—one between each set of adjacent support members. As with the first embodiment the size of the bins  9 ′ generally decreases in size toward the top of the frame as the number mounted on each carousel increases. Preferably as shown with this embodiment the lower two carousels are formed with corner flaps  19  and end flaps  20 . This enables additional smaller bins  21 ,  22  to be mounted alongside the larger bins on these carousels. 
     A modified form of wedge shaped bin for use with the aforementioned carousels is shown in  FIG. 8 . The rectangular bins as shown for example in  FIG. 5  are inefficient when arranged in a circular or polygonal manner as they leave unused space at the front between the sides of adjacent bins. With the wedge shaped bin of  FIG. 8  the front angled panels  23  are together wider than the back panel  24  so that the sides  25  are angled inwardly toward the rear. This reduces or substantially eliminates gaps between adjacent bins and maximises the storage space of the carousel. As with the rectangular bins described earlier there is a downwardly extending tongue  26  and slot  27  formed across the upper edge of the back panel  24  for engaging the carousel frame. 
     It will thus be appreciated that this invention at least in the form of the embodiment described provides a novel and improved form of holder for storage bins. Clearly however the example disclosed is only the currently preferred form of the invention and a variety of modifications may be made which would be apparent to a person skilled in the art. 
     For example:— 
     
         
         
           
             The size, shape and configuration of the bins may be changed according to design preference. 
             The design of the carousel support frames may also change according to installation requirements. They may for example be circular rectangular, or any other shape as required. 
             The invention is not limited to any specific material for constructing the bins and carousel frames although plastic and/or metal is currently preferred. 
             Each carousel may be injection moulded, with the storage bins formed as part of the carousel, or removable. 
             The size of the complete storage carousel may vary according to individual requirements. 
             The storage bins may be fixed to the carousels for safety. 
             The carousels may be supplied individually, with their own central axis, such that they are in a modular form and can be built as required.
