Abstract
A shelving apparatus is provided having a first set of cross members and a second set of cross members which are adapted to slidably couple with one another to form an adjustable shelf. Both sets of cross members have single or plurality of corresponding projecting and female surfaces such that the male surfaces of the first set of cross members are slidably received by the female surface of the second set of cross members. The cross members, which are formed from light-weight material, have a cavity therein which assists in making the shelving apparatus strong and light weight. A support bracket is also provided for additional strength for the shelving apparatus.
Claims15
An adjustable shelving apparatus for use with organization systems, the shelving apparatus comprising:
- a first set of cross members having a length defined by a first end and a second end and comprising at least two cross members each having a first engaging profile defined by a first female surface having at least one female component formed therein and a first male surface, the first female surface extending substantially the length of the cross member, wherein the first female surface defining a substantially enclosed first cavity, said first cavity having a dimension greater than a longitudinally opening therein, the first cavity extending substantially the length of the cross member, the at least two cross members held in parallel spaced apart alignment by a connecting member transverse to the at least two cross members and integral and fixedly connected with the first ends;
- a second set of cross members having a length defined by a first end and a second end and comprising at least two cross members each having a second engaging profile defined by a second female surface having at least one female component therein and a second male surface, the second female surface extending substantially the length of the cross member, wherein the second female surface defining a substantially enclosed second cavity, said second cavity having a dimension greater than a longitudinally opening therein, the second cavity extending substantially the length of the cross member, the at least two cross members held in parallel spaced apart alignment by a connecting member transverse to the at least two cross members and integral and fixedly connected with the second ends;
- where the first male surface of at least one of the first set of cross members substantially corresponding to the second female surface and is adjustably and slidably received within the second female surface of at least one of the second set of cross members;
- and
- where the second male surface of at least one of the second set of cross members substantially corresponding to the first female surface and is adjustably and slidably received within the first female surface of at least one of the first set of cross members,
- wherein the engagement of the male surface and the female surface prevents the engaged surfaces from disengaging laterally.
