Abstract
An attractive, sturdy revolving shelf unit which provides for efficient storage space for books, magazines, or wine bottles etc. Each shelf is characterized by an L-patterned arrangement of vertical supports between shelves which permit efficient storage and provide strength. Methods employed in manufacturing the storage units provide for easy adaptation to different sizes of the storage unit and variation in the size of the L-pattern to accommodate different storage items.
Claims14
A revolving storage shelf unit comprising:
- at least three shelf panels including a bottom shelf panel and a top shelf panel;
- said shelf panels being square planar members, each having four corners and four edges;
- a cover panel;
- a plurality of vertical support members vertically interspacing adjacent shelf panels and defining storage bins, each of said vertical support member having an axis and two planar ends substantially perpendicular to said axis,
- each of said vertical support members includes
- an insert for receiving screw type fasteners in one of said ends axially mounted with said axis, and
- an anchor bolt type fastener in the other one of said ends axially mounted with said axis,
- said anchor bolt type fastener having a wood screw type end and a machine type screw end, said machine screw type end matching said insert for receiving machine screw type fasteners;
- said vertical support members interspacing the same shelf panels constituting a set of vertical support members;
- each set of vertical support members being arranged in "L" patterns, said "L" patterns extending from each corner of a shelf panel with the long side of each L parallel to and proximal to one edge of said shelf panel and extending to a point on said edge, the base of said L extending inward from said edge at said point, the base of the "L" at a first corner along with the long side of an "L" at a second, adjacent corner defining one of said storage bins,
- said "L" patterns of different shelf panels being coaxially arranged, and corresponding vertical support members of said "L" patterns of different shelf panels being axially aligned;
- said cover panel including means for receiving screw type fasteners in locations corresponding to the arrangement of said vertical support members;
- wherein said panels having openings for passing said screw type fasteners in locations corresponding to the arrangement of said vertical support members;
- said bottom panel having openings for receiving screw type fasteners in locations corresponding to the arrangement of said vertical support member;
- said top shelf panel being mounted between said cover panel and the highest set of vertical support members in said shelf unit,
- additional shelf panels being mounted between vertically adjacent sets of vertical support members, and
- said bottom panel being attached to the lowest set of vertical support members;
- a base secured to the bottom of said bottom shelf panel in a freely rotating manner.

A method to manufacture a storage unit, which storage unit comprises one shelf panel, a cover panel, bottom shelf panel, and a plurality of vertical support members;
- which method comprises
- providing said cover panel with inserts for receiving screw type fasteners, said inserts being placed on the underside of said cover panel in a pattern of four L-shaped subpatterns at the four corners of the cover panel, oriented with the side of the L along the edge of the panel and the base extending inward from an interior point along the edge;
- providing each of said vertical support members at one of said ends with axially mounted insert for receiving screw type fasteners, attaching an hanger bolt having a wood screw type end and a machine screw type end, with said wood screw type end to said vertical support member providing cavities in the shelf panels in a pattern of four L-shaped subpatterns at the four corners of the shelf panels, oriented with the side of the L along the edge of the panel and the base extending inward from an interior point along the edge, and of such dimensions as to accommodate said machine screw type end of said hanger bolt,
- said anchor bolt constituting a first screw type fastener;
- providing cavities in said bottom shelf panel in a pattern of four L-shaped subpatterns at the four corners of the shelf panels, oriented with the side of the L along the edge of the panel and the base extending inward from an interior point along the edge, and of such dimensions as to accommodate a second type of screw type fasteners;
- placing said shelf panel over the underside of said cover panel with said cavities in said shelf panel aligned with said inserts in the underside of said cover panel;
- attaching said vertical support members with said first type of screw type fasteners through said cavities in said shelf panel to said inserts in said cover panel;
- placing said bottom shelf panel over said vertical support members with said cavities in said bottom panel aligned with said inserts in said vertical support members and attaching said bottom panel with a second type of screw type fasteners to said inserts of said support members.
5 more elements
A method to manufacture a storage unit, which storage unit comprises at least two shelf panels, a cover panel, a bottom shelf panel, and a plurality of sets of vertical support members,
- said method comprising the steps of:
- providing said cover panel with inserts for receiving a first type of screw type fasteners, said inserts being placed on the underside of said cover panel in a pattern of four L-shaped subpatterns at the four corners of the cover panel, oriented with the side of the L along the edge of the panel and the base extending inward from an interior point along the edge;
- providing each of said said vertical support members with an insert for receiving a first screw type fasteners,
- said insert being axially mounted in one end of said vertical support members;
- attaching an anchor bolt having a wood screw type end and a machine screw type end to the other end of said vertical support members with the machine screw type end extending from said vertical support member,
- said hanger bold constituting a first screw type fastener;
- providing cavities in the shelf panels in a pattern of four L-shaped subpatterns at the four corners of the shelf panels, oriented with the side of the L along the edge of the panel and the base extending inward from an interior point along the edge, and of such dimensions as to accommodate said first type of screw type fasteners;
- providing cavities in said bottom shelf panel in a pattern of four L-shaped subpatterns at the four corners of the shelf panels, oriented with the side of the L along the edge of the panel and the base extending inward from an interior point along the edge, and of such dimensions as to accommodate a second type of screw type fasteners;
- placing a first one of said shelf panels over the underside of said cover panel with said cavities in said first shelf panel aligned with said inserts in the underside of said cover panel and attaching the vertical support members of a set of vertical support members with said first screw type fasteners through said cavities in said first shelf panel to said inserts in said cover panel;
- placing another one of said shelf panels over said support members with said cavities in said another shelf panel aligned with said inserts in said vertical support members and attaching another set of vertical support members with said attached first screw type fasteners through said cavities of said another shelf panel to said inserts of said previously mounted vertical support members;
- and
- repeating the steps of attaching a set of vertical support members and placing a another one of said shelf panels until all sets of vertical support members of the storage unit are installed;
- placing said bottom shelf panel over the last mounted vertical support members with said cavities in said bottom shelf panel aligned with said inserts in said last mounted vertical support members and securing said bottom panel with a second type of screw type fasteners to said inserts of said support members.
